    • 专利摘要:
    A gear finishing machine has a base (1) with an upright (2) which has guides (3) for a vertical slide (4). The movement of the slide is controlled by an electric motor (5) through gears (6, 7) and a screwed rod (8). The finishing tool (14) is mounted on a horizontal axis (41) above the workpiece (20). The finishing tool is driven from an electric motor (25), through a belt drive (26) and cardan shaft (27). This method of driving eliminates the need for bevel gears which are difficult to adjust for zero backlash. It also keeps the driving mechanism clear of swarf during the machining operation.

    专利说明:

    The invention relates to mechanical engineering, in particular, to machines intended for the finishing of the tooth profiles of spur gears, for example, shaving, honing, fine plastic deformation, and the like. A gear-shaping mill is known for finishing the tooth profiles of cylindrical gears under conditions of free rolling with a gear tool containing a frame with a stand on which a guide with a device for setting the axial angle between the tool located in the tool head is mounted with vertical movement. with a horizontal axis of rotation, and a gear wheel to be machined, mounted in the centers of the front and back of the headstock located on the frame with the possibility of adjusting the distance between them (1 this machine design does not allow for automatic approach and removal of the workpiece due to the absence of free passage under the tool, in addition, the responsible guides are placed in the area of chip hit and are at risk of rapid wear. Purpose of the invention - expansion of the technological capabilities of the machine and improvement of its operating conditions. The goal is achieved by the fact that the machine containing the frame with the stand, on the guide A vertical caliper with a device for setting the axial angle between the tool located in the tool head with a horizontal axis of rotation and the gear wheel mounted in the center of the front and rear heads located on the frame with the possibility of adjusting the distance between them, The device for setting the axle angle between the tool, the instrument and the gear to be machined is a carriage made of two parts, the upper part of which is fixed and a support and is guided yuschu vytsolnennuyu as part of an arc in Torah to rotatably around the tool axis of rotation is set lower portion of the carriage comprising a torsion th guide, wherein r iozmo -nostyu rotation around an axis set nortikapnoy toolholder. FIG. 1 shows the proposed machine; FIG. 2 is a view A of FIG. one; in fig. 3 - machine, option; FIG. 4 is a view B in FIG. 3; in Fig.5 is a diagram of the installation of the tool relative to the processed gear; in fig. 6 - circular guide, made in the tool head, cut. On the machine stand 1, a stand 2 is rigidly mounted, on a vertical guide 3 of which a support 4 is movably mounted, driven from a stepper motor 5 mounted on a stand 2, via cylindrical gear 6 and 7, a lead screw 8 and a uterine nut 9, rigidly connected to the caliper 4, on the lower side of which the carriage 10 is mounted. In the lower part of the carriage, the tool head 12 is rotatably mounted in a circular guide 11 around the vertical axis H. In the tool head 12, disk tool 13. On the machine bed 1, the machine is installed in the longitudinal guides 14 of the front 15 and rear 16 headstocks, which are equipped with pins 17 and 18 with centers for mounting and clamping the workpiece 19. To be able to install long parts of the gear shafts rear head 16 located adjacent to the pillar 2 can be displaced into the recess 20 made in the pillar 2. For machining the gear wheel 19, the tool 13 is fed in the direction C and is engaged with the gear wheel 19. The tool 13 is rotated from the shaft 21 The driver 22, located on the rack 2, through the pulley of the belt drive 23, the propeller shaft 24 and the cylindrical gear 25, 26. In the rack 2 there is an opening 27 through which the propeller shaft 24 passes. In FIG. 3 and 4 depict a variant of the layout of the machine parts for machining long shafts-gears. On the side of the frame 28 is rigidly mounted vertical stand 29 with the console 30, on which are located
    311
    guides 31 along which the caliper 4 moves,
    The arrangement of the stand 29 next to the machine bed 28 provides the possibility of using the entire length of the machine bed for the guides 14 of the heads 15 and 16, which allows machining of long parts. In this case, automatic approach and removal of the part is possible from the free longitudinal side of the bed 28.
    The process of processing tooth profiles on the machine. This is done when the tool axis F is installed at an angle t to the axis of the gear wheel D being machined, and the tool 13 can rotate around the horizontal axis N, which is perpendicular to the vertical axis of the tool 13 and the horizontal axis m of the gear wheel 19,
    The ability to rotate and install the tool 13 is provided by making the carriage in two parts: the upper part 32 is rigidly mounted on the support 4, and its lower part 33, on which the tool head 12 is placed in the circular guide 11, is installed in the circular guide 34, made as part of an arc that allows the tool to rotate around the N axis.
    At the free end of the spindle 35, a spindle screw rotation mechanism (not shown) can be fitted with a screw installed on it, which interacts with the corresponding segment of the worm wheel installed in the lower part of the mounting carriage 33 (the worm wheel and the worm are not shown). The same applies to the devices for clamping the lower part of the mounting carriage in the desired position. Since the tool head 12 is rotatably mounted in a circular guide 11, made in the lower part 33 of the carriage 10, it is possible to adjust the crossing angle j of the axes (Fig. 5). between the tool axis F and the part axis M.
    The presence of the drive shaft 24 provides kinematic communication when the position of the tool axis F relative to the engine axis 22 due to different sizes of machining064
    parts and vertical tool movements during each machining cycle.
    In order to avoid the tool head 12 sagging in the circular guide, in the latter there is provided a rolling bearing 37 preloaded by spring 36 (Fig. 6). The outer ring of the ball bearing 37 rests on the retaining ring 38 installed in the undercut 33 of the carriage 10. The inside of the bearing 37 is mounted in the support ring 39, which is centered by the undercut 40 with the centering ring 41 on which the tool head 12 is mounted.
    J
    Concentric to the recess 40 in the support ring 39 there is a recess 42, against which the end of the spring 36 mounted on the sleeve with shoulder 43 rests. The spring force is controlled by a screw 44 installed in the threaded hole of the sleeve 43. To ensure constant contact of the upper end surface P of the tool head 12 and the lower end surface Q of the lower part 33, in the bearing 37, there should be no axial play, which is provided by the preliminary stress of the spring 36, the force of which must be greater than its own weight heads 12 with tool 13 and propeller shaft 24.
    In the annular groove 45 of the lower part 33 there are screws 46 with nuts 47 and washers 48 for securing the tool head 12 in the required angular position T -. The tool is brought to the part and the tool is retracted using a stepper motor 5 with an adjustable rotational speed.
    To hold the caliper 4 in a certain position, devices (not shown) are provided, for example, hydraulic clamping devices.
    Thus, placing the guides 3, 1, 1 and 34 above the location of the workpiece 19 and the tool 13 ensures their protection from chips, and setting the axis of the gears to be machined is always at the same height, regardless of their diameters, allows automatic supply and removal of parts in the processing area.
