Method and apparatus for realizing rapid axial feed on precise machine tool

Abstract

The invention relates to a device for realizing quick axial feed on a precision machine tool. A tailstock of a tailstock mandrel 12 is fixed on a sliding guide rail of the machine tool, and the tailstock mandrel is provided with an axle hole 11 and does axial reciprocating rectilinear motion along the axle hole. A spanner 13 consists of two sections of rotatable connecting rods, wherein one section is fixed at the tail of the tailstock mandrel, and the other section is fixed at the side of the axial hole; and a T-shaped push-pull sliding block 10 and a C-shaped guide groove 9 are connected to the axial hole, the other end of the C-shaped guide groove is fixed with a tool holder 6 through a bolt, and the tool holder is provided with a turning tool 8. A collar 2 to be processed is arranged in a spring collet 1 and tightened, the turning tool 8 is axially close to the collar, the spanner is pulled to drive the turning tool to axially contact the collar, a vehicular chamfer angle is turned to the required size to finish processing amount, the spanner is pulled reversely to make the turning tool leave the collar, and the processed collar is removed. Rotary feed of a screw rod of a small splint is changed into linear quick feed, so as to achieve the aim of quickly processing bearing collars in bulk; and the device has the advantages that the device has a simple and practicable structure, can improve production efficiency greatly, and reduce work intensity.

Description

technical field [0001] The invention belongs to the technical field, in particular to a method and device for realizing rapid axial feed on a precision machine tool. Background technique [0002] For the chamfering and groove processing of the bearing ring, it is usually done on the C0520 precision machine tool. Processing method see figure 1 , the processing process is: [0003] 1. Put the ferrule (2) to be processed into the collet (1) and tighten it; [0004] 2. Fix the large supporting plate (3) in an appropriate position, turn the large supporting plate screw (7) so that the turning tool (8) mounted on the tool holder (6) is radially close to the ferrule (2); [0005] 3. Rotate the small pallet screw (5) to drive the turning tool (8) on the small pallet (4) and the tool holder (6) to axially contact the ferrule (2), and chamfer the corner to the required size to complete the processing amount; [0006] 4. Rotate the small pallet screw (5) in reverse to make the turn...

AI Technical Summary

Problems solved by technology

[0009] In the above processing process, there must be enough space in the ferrule processing area, so that the small pallet (4) must move to the right as far as possible when the ferrule is loaded and unloaded, because the hand wheel of the small pallet screw (5) rotates once circle, the small pallet (4) only travels the pitch distance of one lead screw, so it takes many circles of rotation to exit the working area, which will increase labor intensity and processing time
