Description
Title of the invention: Laser level indicator without physical adjustment and its method of assembly and processing Technical field of the invention The present invention relates to the technical field of level indicators and more particularly to an indicator level laser without physical adjustment and a method of assembly and processing thereof.
Background of the invention [0002] A laser level indicator is a device capable of guiding the laser beam emitted by the laser emitting device in its telescopic tube, thus allowing the laser beam to be emitted in the direction of the collimation axis. Laser level indicators are used whenever it is necessary to obtain precise verticals and horizontal lines. The vertical laser beam emitted by the laser emitting device can be refracted and rotated in the laser level indicator, to be emitted in different horizontal directions of the same axis, at different times. Laser beams emitted at different times form a laser collimation plane which is parallel to the horizontal plane. When the frequency of rotation is high enough, the human eye can perceive a laser plane. Laser level indicators are widely used in the fields of surveying, engineering and construction.
In the prior art, most of the traditional laser level indicators sold have an integrated base, with different mounting positions. Various components must be mounted on the aforementioned base, which considerably increases the assembly difficulties. Therefore, the slightest assembly error can affect the accuracy of the laser collimation plane formed by the laser level. On the other hand, the finished product can only function normally after a complicated adjustment. Moreover, since all the mounting positions on the base are created at the same time, mismatches between the mounting positions and the components inevitably lead to assembly errors. Worse still, assembly errors and processing errors of the components themselves can add up, leading to reduced standard reference accuracy of the laser collimation plane formed by the laser level indicator.
Summary of the invention The object of the present invention is to solve the drawbacks of the state of the art by proposing a laser level indicator without physical adjustment, as well as a method of assembling and processing that. -this.

As shown in Figures 1 to 9, the present invention discloses a laser level indicator without physical adjustment which comprises a base assembly 10 and a cover assembly 20, knowing that the base assembly 10 and the cover assembly 20 are fixedly connected. The base assembly 10 further comprises a base chassis 11. M connecting rods 12 are fixed to the base chassis 11, m being an integer greater than or equal to 3.

The rigid nut column 22 projects outwards from the covering body 21 and is connected to the connecting rod 12 by a screw.
A light emitting mechanism mounting seat 30 is fixed to the base frame 11, and a light emitting mechanism 40 is connected to the light emitting mechanism mounting seat 30 by screws. The light-emitting mechanism mounting seat 30 is provided with n convex mounting blocks 31, where n is an integer greater than or equal to 3. The convex mounting block 31 is provided with a first screw hole 311, and this first screw hole 311 extends through the base frame 11. The light emitting mechanism 40 comprises a light source support envelope 41 and a light source 42 which is fixed in the light source support envelope 4L Preferably, the light source 42 is a laser diode. An annular protruding mounting portion 44 is attached to a face of the mounting disc 43 which is remote from the light emitting face of the light source 42. An inner ring of the annular protruding mounting portion 44 is spaced from the light source support envelope 41, thereby preventing the light source support envelope 41 from interfering with further processing. Second screw holes 441 are formed in the annular projecting mounting portion 44. The second screw hole 441 also extends through the mounting disc 43 and matches the first screw hole 311.

The light source 42 in the light emitting mechanism 40 emits fine light beams towards the refraction mechanism 60 located above, and the rotation mechanism drives the refraction mechanism 60 in rotation. The rotating refraction mechanism 60 refracts the fine light beams toward the periphery of the horizontal plane, thereby forming a laser collimation plane which is parallel to the horizontal plane.
According to the present invention, the base assembly 10 and the cover assembly 20 can be preassembled, which avoids assembling all the components at the same time. This effectively reduces assembly difficulties. The base assembly 10 and the cover assembly 20 are rigidly connected and are further provided with processing support elements to facilitate subsequent processing. Therefore, the accuracy of the present invention can be increased significantly.

All the convex mounting blocks 31 are distributed in a circle of diameter P, with P> 27 mm. The height of the annular protruding mounting part 44 which extends from the mounting disc 43 is 0.5 to 1 mm, the diameter of the outer ring of the annular protruding mounting part 44 being greater than or equal to 27 mm. The projecting height of the convex mounting block 31 and the annular projecting mounting portion 44 is 3.5 to 4 mm. This design allows for a supporting element for the subsequent surface milling process which does not interfere with the assembly of other components and can be easily processed. The formula for calculating the outside diameter of the surface to be treated is j = i / tank, where i is the processing precision of the milling machine, j is the outside diameter of the surface to be treated, and k is the precision of processing and shaping. When using a milling machine with an accuracy of 0.005 mm, the rotation diameter of the cutter or the rotation diameter of the processing surface must be greater than or equal to 27 mm, the requirement for processing accuracy and formatting being 0 <k <37 ”.
In this embodiment, the rotation mechanism comprises a hollow rotary shaft 51, and a rotary disc 52 is fixed to one end of the hollow rotary shaft 51 which is located near the base assembly 10. The other end of the hollow rotary shaft 51 is the outlet end of the rotation mechanism. The hollow rotary shaft 51 is installed in the ball joint shaft 212 by means of a bearing 53. The rotation mechanism further comprises a rotary drive motor 54, and the output end of the motor d the rotary drive 54 is connected to the rotary disc 52 by a belt 55. The rotary drive motor 54 drives the hollow rotary shaft 51 in rotation via the belt 55, thereby allowing the refractive mechanism 60 to the hollow rotary shaft 51 to rotate together.
In this embodiment, the radius of the column-shaped internal cavity of the hollow rotary shaft 51 is defined by R, and the radius of the light beam emitted by the light source 42 is defined by r, knowing that r <R. With this design, it is possible to prevent the shape and / or the direction of the light beam emitted by the light source 42 from being influenced by the hollow rotary shaft 51.
In this embodiment, a magnetic coding disc 521 is fixed to the rotating disc 52, and a photoelectric sensor is arranged in the covering body 21. The detection part of the photoelectric sensor is located opposite screw of the magnetic coding disc 521. The magnetic coding disc 521 is provided with black and white interphase lines, thus making it possible to transmit to the photoelectric sensor, pulse signals generated using a rotary coding disc 62. In this way, it is possible to monitor and regulate the rotation speed of the rotating disc.
In this embodiment, the spherical end of the ball joint shaft 212 is connected to a spherical limitation block 71, and a clamping plate 72 is arranged between the spherical limitation block 71 and the covering body 21.

A method of assembling and processing the laser level indicator without physical adjustment comprises the following steps:
Step 1: making the base frame 11, the covering body 21 and the light emitting mechanism 40, by a machining process, where the base frame 11, the covering body 21 and the emitting mechanism light 40 are respectively provided with mounting positions for pre-assembly;
Step 2: fixing of the x level axis bubble 13, of the y level bubble 14 and of the z level bubble 15 in the base frame 11, where the bubble d the x-axis 13, the y-axis bubble 14 and the z-axis bubble 15 are level adjustment mechanisms;
Step 3: setting up the base frame 11 in a milling machine, and leveling the base frame 11 using the axis level bubble x 13, the axis level bubble y 14 and the z-level level bubble 15; then, treatment of the end surfaces of the connecting rods 12 and those of the convex mounting blocks 31, by a milling process, thus making it possible to ensure that the end surfaces of the connecting rods 12 and those of the blocks convex mounting 31 are parallel to the xy plane, that the end surfaces of all connecting rods 12 are coplanar, and that the end surfaces of all convex mounting blocks 31 are coplanar, that is, say allowing the level adjustment mechanisms to act directly on the convex mounting blocks 31 and on the connecting rods 12, thereby avoiding adjustment failures of the convex mounting blocks 31 and the connecting rods 12 which are caused by different factors;
Step 4: tightening the light emitting mechanism 40 in a rotary calibration device and setting up a CCD screen, at a distance ranging from 80 to 120 m relative to the light emitting mechanism 40; driving the light emitting mechanism 40 so that it rotates in the rotary calibration device, and adjusting the position of the light emitting mechanism 40, until the projection of the light emitting mechanism 40 in rotation, on the CCD screen is changed from a circle to a point, the CCD screen obtaining precise images from a connected computer, and the milling machine processing the end surface of the annular protruding mounting part 44 of the mechanism light emitter 40 having an adjusted angle, thereby ensuring that the end surface of the annular protruding mounting portion 44 is parallel to the xy plane, and that the end surface of the annular protruding mounting portion 44 is perpendicular to the optical axis of the light beam emitted by the light source 42;
Step 5: fixing the ball joint shaft 212 in the ball joint mounting seat 211, and fixing the rigid nut columns 22 in the covering body 21, using a sealing adhesive ; then, fixing of the covering body 21 in the milling machine, due to the interaction between the ball joint shaft 212 and the clamping device, and treatment of the end surfaces of the rigid nut columns 22, by a milling process, thus ensuring that the end surfaces of the rigid nut columns 22 are parallel to the xy plane, that the center of the axis of the ball joint shaft 212 is perpendicular to the end surfaces of the rigid nut columns, and that the surfaces d the end of all the rigid nut columns are coplanar;
Step 6: Solid fixing of the end surfaces of the convex mounting blocks 31 to the end surface of the annular projecting mounting part 44, and fixing of the light emitting mechanism 40 in the mechanism mounting seat light emitter 30, using screws; next, installation of the rotation mechanism in the ball joint shaft 212, and fixing of the refraction mechanism 60 at the outlet end of the rotation mechanism; solid fixing of the end surfaces of the connecting rods 12 to the end surfaces of the rigid nut column 22, and fixing of the covering body 21 in the base frame 11, using screws, thus allowing the mechanism to level adjustment to effectively adjust the laser beam emitted by the present invention.
In the present invention, the level adjustment mechanisms are fixed in the base frame 11, before the end surfaces of the convex mounting blocks 31 in the light emitting mechanism mounting seat 30 are treated. . Thus, the result of the adjustment of the level adjustment mechanism can be directly returned to the convex mounting blocks 31, thus preventing the accumulation of assembly and processing errors. As a result, large assembly errors can be effectively avoided. Likewise, the end surfaces of the light-emitting mechanism 40 and of the covering body 21 are treated after the assembly of their semi-finished products. Since the errors of each position can be reduced significantly, the present invention can be used directly, without adjustments, and it is possible to achieve higher precision of the laser collimation plane emitted according to the present invention.
To further improve the precision of the light emitting mechanism 40 adjusted by the level adjustment mechanisms, steps 3 and 4 of this embodiment provide that the diameter of the end surface of the convex mounting block 31 is defined by p, and that the edge length of the cutter in the milling machine is defined by L, knowing that p <L. The width of the end surface of the annular projecting mounting part 44 is defined by q, and q <L. Thanks to this design, the convex mounting blocks 31 and the annular projecting mounting part 44 can be produced in the same cut, thus protecting the precision of the end surface from being subjected the consequences due to a combined surface formed by multiple cuts.
During steps 3, 4 and 5 of this embodiment, the outside diameter of the surface to be treated can be provided in accordance with the formula j = i / tank, where i is the processing precision of the milling machine , which is normally 0.01 mm or 0.005 mm, j is the outside diameter of the surface to be treated and is also the rotational diameter of the cutter or that of the surface to be treated, and k is the processing precision and shaping.
