    A grinding head has at least one expandable grinding tube mounted on an expansion cone. The expansion cone is carried by, and is rotatable with, an expansion rod which is coupled for rotation with a driven part of the head. The expansion rod and cone are movable by means of a ram to cause expansion and contraction of the grinding tube. The connection between the ram and expansion cone via the expansion rod includes helical coupling means whereby to cause a step-down in the effective stroke of the ram as applied to the expansion cone, which enables high accuracy in the expansion and contraction of the grinding tube.

    The invention relates to the final machining of parts and can be used to fine-tune the holes. A device for final machining of parts is known, comprising a base bearing rotatably mounted tool head with a rotating assembly and an expanding rod with its displacement unit connected to the cylinder kinematically. . However, the known device does not provide the products with the required accuracy. The purpose of the invention is to provide high precision machining by improving the operation of the displacing rod displacement unit. The goal is achieved by the fact that the cylinder is located coaxially with the tool head, and its kinematic connection with the displacing rod displacement unit is carried out through the turbulence supplied with the bearing and the rollers and the stem with the helical surface, the coupling is installed with the possibility of rotation and translational movement and is connected with the strut by means of a bearing, and with the rod and the node of rotation there are tools. Hoist, Noah head - through the rollers. Moreover, the instrumental head is mounted with the possibility of adjusting the angular position relative to the node of rotation. The tool holder is installed with the possibility of rotation relative to the movement unit of the expanding rod. In addition, the rotation unit is provided with segments for axially fastening the tool head. FIG. 1 shows the device, a general view} on. 2 - upper part of the axial section; in fig. 3 - head, middle part, axial section; in fig. 4 - head, bottom part, axial section; in fig. 5 - section aa 2; in fig. 6 is a section BB in FIG. 3; in fig. 7 is a section on BB in FIG. 8- raz G-4; in fig. in fig. four; in fig. 9 is a sectional view in FIG. in fig. four. . The device consists of a tool head, including a tool 1, mounted on the expanding rod 2 and made in. as a tube, one end of which is covered with diamond
    crumbs and interacts with the workpiece 3, and the other by means of an external cone 4 and a nut 5 is fixed in the tool holder b installed with the washer 7 and the ring 8 on the bearing 9. The nut 10 BEARING: 9 is fixed in the pipe 11. The tool head is attached to the node of its rotation consisting of a housing 12, bearing on bearings 13 and 14, a hollow shaft 15, on the upper end of which a pulley is mounted, 16. A torque from the pulley 16 is transmitted to the hollow shaft 15 by a key 17. Axial mounting of the pulley 16 on the stem 15 performed by 18. A tapered bore is made at the lower end of the empty shaft 15, in which the intermediate shaft 19 is fixed. Fastening is carried out with a nut 20, which interacts with the intermediate shaft 19 through balls 21, which are filled through a hole in nut 20 that is plugged with a plug 22. The screw 23 stops the angular movement 20 relative to the intermediate shaft 19. The twisting moment from the hollow shaft 15 to the intermediate shaft 19 is transmitted by a pin 24. Radial slots 25 are made on the intermediate shaft 19. The screws 26 are tightened, possibly partially eliminated it curvature of the intermediate shaft 19. At the lower end of the intermediate shaft 19 cut grooves into which are embedded segments 27, binding in the axial direction of the pipe 11 and the intermediate shaft 19 with the toolholder assembly of its rotation. The ring 28 mounted on the intermediate shaft 19 ,. using rings 29 prevents segments 27 from falling out. The torque from the intermediate shaft 19 of the tool head is transmitted through the keyway and the pin 30 fixed by the elastic insert 31 on the axially movable sleeve 32, the lower end of which is designed as an internal gear with a small tooth interacting with the external gear of the pipe 11. In the coupled state, the sleeve 32 is held by the spring 33. The axial movement of the expanding rod. 2 is carried out by its displacement unit consisting of a hollow screw.
    .34 associated with an expanding rod 2 of the tool head with a screw 35. A hollow screw 34 interacts with a nut that has been cut in the internal cavity of pipe 11. The displacing rod displacing unit is kinematically connected to a cylinder 36 installed coaxially with a toolhead through a rod 37, a glass 38 and the coupling 39 with the bearing 40 and the rollers 41 and 42, planted on the axis 43 and 44, respectively. Clip 41
    enters the longitudinal groove of the hollow shaft 15. The rollers 42 are in contact with a flat screw surface made in the upper part of the rod 45. A thread 45 in its middle part 5 the rod 45 contacts with a nut 46 fixed in the hole of the intermediate shaft 19. The lower end of the rod 45 is made multi-faceted and enters the hole of the hollow screw 34 Q of the movement unit of the expansion rod. The device is attached to the base 47 by means of the housing 12 and screws 48.
    The device works as follows.
    S The rotation from the pulley 16 is transmitted to the hollow shaft 15, the intermediate shaft 19, the sleeve 32, the pipe 11 and the tool 1. The rotating tool 1 is inserted into the hole of the workpiece 3. The sleeve 39 rotates with the rollers 41 and 42 simultaneously with the hollow shaft 15 and rod 45, hollow screw 34 and expansion rod 2. Next, the tool is expanded
    5 1 in such a way that it is all the time in contact with the surface of the workpiece 3. For this, pressure is applied to the cylinder 36. The rod 37 moves downward, communicates the movement of the coupling 39. Due to the contact of the rollers 42 with the gentle screw surface of the upper part of the rod 45, the hollow screw 34 rotates. As a result, the expansion rod 2 moves axially downwards, which leads to an increase 1. After the rod 37 is moved to a predetermined amount, the processing is stopped, the rod 37 returns to its original position, the diameter
    0 of tool 1 is reduced and it is output from the machined hole. Part 3 is replaced and the processing cycle can start over.
    With the device design allows
    change the final diameter of the tool. To do this, the tool head is stopped, the sleeve 32 is raised, the toothed rims of the sleeve 32 and the pipe 11 are disengaged, after which the pipe 11 is turned to the required value. The expansion rod 2 moves, which leads to a change in the diameter of the tool 1.
    5 Location of the cylinder coaxially with the tool head and performing its kinematic connection with the unit for displacing the expanding rod through the coupling with the bearing and rollers
    0 and a rod with a helical surface, as well as providing the possibility of adjusting the angular position of the tool head relative to the rotation unit, allows to increase
    5 processing accuracy.
