Abstract

The utility model relates to a tailstock box hole wearing and tearing compensation structure, including box, sleeve and the tight subassembly that expands, the sleeve is flexible removal in the box, and the tight subassembly cover that expands is established between box and sleeve, and the tight subassembly that expands includes gland and the cover that expands, and the gland wears to establish on the sleeve and establishes the one end at the box through the screw, and the cover that expands wears to establish between box and sleeve and with the gland butt, the utility model discloses an increase the tight subassembly that expands between box and sleeve, the hole shrinkage of the cover that expands is controlled through the locking force of control screw to change the clearance size between the cover that expands and the sleeve, realize box and telescopic wearing and tearing compensation, prolong the life of tailstock, the box keeps higher cooperation precision with the sleeve, improves processingquality.

Description

Tailstock box body hole abrasion compensation structure

Technical Field

The utility model relates to a metal cutting machine tool field indicates a tailstock box hole wearing and tearing compensation structure especially.

Background

As can be seen from fig. 6 to 7, the conventional tailstock mainly comprises a box body, a sleeve and the like, the box body and the sleeve are in clearance fit and slide, and are driven by hydraulic pressure or air pressure to have a telescopic function, and after the box body and the sleeve are used for a long time, the clearance is larger and larger, so that the fit precision of the box body and the sleeve is lower and lower, the processing quality is affected, the tailstock needs to be frequently replaced, and the service life of the tailstock is short.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides an extension tailstock box hole wearing and tearing compensation structure of life.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a tailstock box body hole wearing and tearing compensation structure, includes box, sleeve and the tight subassembly that expands, the sleeve is flexible removal in the box, the tight subassembly cover that expands is established between box and sleeve, the tight subassembly that expands includes the gland and the cover that expands, the gland is worn to establish on the sleeve and is established the one end at the box through the screw, the cover that expands is worn to establish between box and sleeve and with the gland butt.

Preferably, the sleeve is connected with a processing mechanism.

Preferably, the gland ring is provided with a plurality of through holes corresponding to the positions of the mounting holes of the box body.

Preferably, the end face of the gland is provided with a convex part, and the convex part is inserted into the box body and abutted against the expansion sleeve.

The beneficial effects of the utility model reside in that: the utility model discloses an increase the tight subassembly that expands between box and sleeve, the hole shrinkage of the cover that expands is controlled to locking force through control screw to the clearance size between cover and the sleeve that expands is changed, realizes box and telescopic wearing and tearing compensation, prolongs the life of tailstock, and box and sleeve keep higher cooperation precision, improve processingquality.

Detailed Description

Referring to fig. 1-5, the present invention relates to a tailstock box 1 hole wear compensation structure, which comprises a box 1, a sleeve 2 and an expansion assembly, wherein the box 1 is provided with a through hole, the sleeve 2 is inserted into the through hole, the sleeve 2 is connected to a processing mechanism 5, the sleeve 2 is driven to move in a telescopic manner by hydraulic pressure or pneumatic pressure, one end of the through hole is provided with a circle of limiting groove, one end surface of the box 1 is provided with a plurality of mounting holes, the expansion assembly comprises a gland 3 and an expansion sleeve 4, the expansion sleeve 4 is sleeved outside the sleeve 2, the expansion sleeve 4 is arranged in the limiting groove, the gland 3 is provided with a plurality of through holes 31 corresponding to the mounting holes, the gland 3 is connected with the mounting holes by screws passing through the through holes 31, the end surface of the gland 3 is provided with a convex portion 32, the convex portion 32 is inserted into the through hole and abutted to the expansion sleeve 4, the depth of insertion of convex part 32 is adjusted to the locking force through control screw for 4 deformations of cover expand, change the hole shrinkage of the cover 4 that expands, thereby change the clearance of expanding cover 4 and sleeve 2, compensation sleeve 2 causes the clearance variation between sleeve 2 and the perforation because of the motion friction, makes sleeve 2 and box 1 keep higher cooperation precision, prolongs the life of tailstock, improves processingquality.

The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
