Abstract

Use: in the repair of fillets, grooves dovetail compressor disks. SUMMARY OF THE INVENTION 1 The device comprises a device for mounting and rotating the product, a slider with a tool, a mechanism for fixing the position of the grooves of the product, comprising a guide sleeve stationary relative to the slider and a fixing element spring-loaded relative to it with a drive of its truncated cone. Using the aforementioned drive, the locking element is lowered to the position of contact of the surface of the locking head with the working surfaces of the groove along the cone forming part. 10 il.

Description

The invention relates to mechanical engineering and machine-tool construction and is intended for use in the repair of devices having a multi-phase structure, for example, in the repair of filings of grooves of dovetail compressor disks.

The purpose of the invention is to improve the processing accuracy of dovetail type slots.

This goal is achieved by the fact that the mechanism for fixing the position of the grooves of the product is provided with a locking head made in the form of a truncated cone and fixed on the locking element,

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view along arrow A in FIG. 1 in FIG. 3 — machined groove; in fig. 4 - the relative position of the surfaces of the groove and the locking head at the moment of insertion of the latter into the groove; on

FIG. 5 - the relative position of the surfaces of the groove and the locking head at the time of turning the product; in fig. 6 - the relative position of the surfaces of the groove and the locking head in the fixed position of the disk; in fig. 7 is a section BB in FIG. 6; Fig. 8 shows the relative position of the device for mounting and rotating the product, the tool; in fig. 9 is a view along arrow B in FIG. 8; FIG. 10 is a view along arrow D of FIG. eight.

A device for machining grooves of products includes a slider 1 with a tool 2 - draw, a device 3 for mounting and rotating an article, such as a disk 4, a mechanism for fixing the position of the grooves 5 of the product placed on the slider and intended for contacting with the grooves 5.

The product contains a guide sleeve 6 that is fixed relative to the slide and a locking element 7 spring-loaded relative to it, with its movement being driven. The guide sleeve 6 is installed in the hole 8 of the slide and secured with screws 9, and the drive for moving the locking element 7 includes a spring 10, a lever 11 with an axis of rotation 12 fixed to the bracket 13, a bolt 14 connected to the lever 11 via an axis 15, a nut 16 and spherical 17 and conical 18 washers. In the slider 1 there is additionally made a longitudinal groove 19, in which the fixing element 7 is mounted and the tool 2 is fixed. The fixing mechanism of the grooves 5 of the product is provided with a fixing head 20 in the form of a truncated cone and fixed on the fixing element 7. The longitudinal axis 21 of the fixing element 7 and the axis 22 devices for mounting and rotating the product are placed in the plane of symmetry of the tool and are perpendicular to each other. The reciprocating movement of the locking element is limited by the adjusting 23 and the counter 24 screws.

In the initial (unlocked) position between the end surface 25 of the fixing head 20 and the bottom surface 26 of the groove 5 there is some gap e, and between the working surface 27 of the fixing head 20 and the working surfaces 28 of the groove 5 there is a gap 5i. The gaps d and 5i are provided with screws 23 and 24. In the fixed position between the surfaces 25 and 26, a certain gap 5g forms, defined by the ratio

di d + h

where h is the stroke of the fixing head 20, while the working surface 27 of the fixing head 20 contacts with the working surfaces 28 of the groove 5 along the generatrix of the cone.

The device works as follows.

The compressor disk is mounted on the shaft of the device 3 for mounting and rotating the product with the possibility of angular movement. The working slide of the horizontal extension machine through the cartridge provides the movement of the slide 3 with the mechanism for fixing the position of the grooves 5 of the disk 4.

The spring-loaded locking element 7, moving along the guide sleeve 6, is inserted into the groove 5 with a hand drive with some gaps d and di. With the help of the said hand drive the locking element is lowered until the contact surface 27 of the locking head 20 with the work surfaces 28 of the groove 5 forming a cone. In the case of non-contact surfaces 27 and 28

forming a cone, the rotation of the disk 2 compressor using a manual drive. Groove 5 is fixed. The compressor disk 2 with the fixed groove 5 is fixed on the shaft of the device 3 for

setting and turning the disc 4, then the locking element is released with the help of a manual drive. Groove 5 is ready for finalization with a wire.
