Problems solved by technology

[0002] In the lathe tailstock in the prior art, the telescopic movement of the sleeve is regulated by the rotation of the screw. After loading the top, we need to shake the sleeve out by rotating the hand wheel. The extension speed of the entire sleeve depends on the handwheel. The speed of shaking and the pitch of the screw, the sleeve protrudes from the innermost end to the longest, and the time spent in the middle is relatively long, unless it is very fast shaking, otherwise it is difficult to shake out the sleeve quickly, so the working efficiency Low, labor-intensive, in many emergency situations can not be adjusted to the length of the required sleeve immediately

Embodiment Construction

[0012] Such as figure 1 As shown, it includes a sleeve, a nut 3, a screw 2, a top 9 and a hand wheel 1. The nut 3 is fixedly installed in the sleeve. There is a threaded hole in the middle of the nut 3. The screw 2 passes through the threaded hole in the middle of the nut 3 and extends In the sleeve, the top 9 is installed at the front end of the sleeve, the rear end of the top 9 is against one side of the screw, and the handwheel 1 is fixedly installed on the outer end of the screw 2. The sleeve includes a first sleeve 5 And the second sleeve 4, movable assembly between the first sleeve 5 and the second sleeve 4, the outer ends of the first sleeve 5 and the second sleeve 4 are respectively provided with a convex portion 6, and the two convex portions 6 is bent outward, and an extrusion cavity is formed between the opposite surfaces of the two convex parts 6. An arc-shaped positioning groove 13 is provided on the opposite surfaces of the tail ends of the two convex parts 6, an...

Abstract

The invention discloses a movable tailstock sleeve, which comprises a sleeve, a nut, a screw rod, a tip and a hand wheel. The nut is fixedly installed in the sleeve, and a threaded hole is arranged in the middle of the nut. The screw rod passes through the threaded hole in the middle of the nut and It extends into the sleeve, the tip is installed in the front end of the sleeve, the rear end of the tip is against one side of the screw, and the hand wheel is fixedly installed on the outer end of the screw. The sleeve includes a first sleeve and a second The sleeve, the first sleeve and the second sleeve are movable assembled, and the outer ends of the first sleeve and the second sleeve are respectively provided with a convex part, and the two convex parts are bent outward, and the opposite sides of the two convex parts An extrusion cavity is formed between the surfaces, and an arc-shaped positioning groove is provided on the opposite surfaces of the tail ends of the two convex parts. The tailstock sleeve of the present invention can realize movable extrusion, so that the rear end of the sleeve can be separated from the engagement section of the screw rod, realize rapid sliding of the sleeve, increase the extension speed of the inner sleeve of the tailstock, and improve work efficiency.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a movable tailstock sleeve. Background technique [0002] In the lathe tailstock in the prior art, the telescopic movement of the sleeve is regulated by the rotation of the screw. After loading the top, we need to shake the sleeve out by rotating the hand wheel. The extension speed of the entire sleeve depends on the handwheel. The speed of shaking and the pitch of the screw, the sleeve protrudes from the innermost end to the longest, and the time spent in the middle is relatively long, unless it is very fast shaking, otherwise it is difficult to shake out the sleeve quickly, so the working efficiency Low, labor-intensive, in many emergency situations can not be adjusted to the length of the required sleeve immediately. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a movable tailstock sleeve, which ca...
