Description

(5TH DEVICE FOR PREVENTION OF FLEXIBLE BENDING OF PARTS HAVING A FORM OF BODIES OF ROTATION

V

This invention relates to metalworking, in particular, to machining non-rigid parts on lathes.

A device is known that is made in the form of a horizontal abutment cutter located on the opposite side, one end of which is clamped by an elastic element, and at the other end of the abutment is installed with the possibility of turning (roller 1).

The disadvantage of the device is that it does not ensure the elimination of deflections of non-rigid conical shaped parts that occur during their processing.

The aim of the invention is to improve the processing accuracy of conical parts.

This goal is achieved by the fact that the proposed device is equipped with brackets mounted on the frame and guides for bushings with stops and rollers, the ends of which are hingedly mounted on one bracket, and: on the other, they are installed with possibility of movement.

FIG. 1 shows the device, a general view; in fig. 2 - the same cross section.

The device contains two brackets 1, attached to the frame of the machine slats 2. One bracket is fixed near the front of the headstock, and the other near the back headstock of the machine. The brackets are interconnected by two cylindrical longitudinal guides 3 located in different planes. Guides 3 with one bracket are connected by a hinge, and with another freely, which allows you to adjust the guiding of the guides due to their displacement along the groove, performed by the bracket, and fix it with an iinta C at a certain taper angle of the workpiece. Bearing 5 is attached to the caliper of the machine and is made in the form of a bracket with two through 3956 windows. The guides 3 are mounted with the possibility of moving through them the bushings 6, inserted into the through windows of the support 5, for a horizontal stop 1 located on the opposite side of the tool, and an additional stop 8, which presses the product from above and prevents the part from deflection from cutting force P. stops 7, 8 are installed rollers 9, the adjustment of which to the corresponding diameter of the part is carried out by ring nut 10 and fixed by screw 11. The device operates as follows. When machining the workpiece, the stops and rollers 9 are adjusted to the appropriate diameter with a nut 10 and secured with a screw 11. When the taper parts are drilled, the device works in conjunction with a copy rule. Additionally, the guides 3 are adjusted, which are mounted parallel to the generatrix of the conical part by displacing them along a groove made in the bracket 1, and are fixed with a screw. Bearing 5 moving together with the caliper, leads stops 7 8 with rollers 9 after the cut and prevents deflection of the workpiece. The proposed device allows an increase in the machining accuracy of non-rigid conical parts by eliminating the deflections of the parts. The invention of the device for preventing pro- bending of parts in the form of rotation bodies, comprising a support mounted on a support with windows in which sleeves with supports and rollers are placed, characterized in that, in order to improve the accuracy of parts with conical generators, the device provided with brackets mounted on the frame and guides for bushings with stops and rollers, the ends of which are hinged on one bracket, and mounted on the other with a possibility of movement.
