Self-tightening and position-adjustable tailstock for grinder

Abstract

A self-tightening and position-adjustable tailstock for a grinder comprises a sleeve which is arranged inside a tailstock case body and is provided with a Morse tapered hole. The self-tightening and position-adjustable tailstock is characterized in that a longitudinal guide slot is arranged on the surface of the sleeve; the guide slot is connected with a guide key arranged inside the tailstock case body so as to be enabled to slide along the guide key; the non-working end of the tailstock case body is fixedly connected with a cylinder; the piston rod of the cylinder penetrates through the centers of a front end closure and a back end closure; and one end of the piston rod is provided with an external thread and inserted into the inner hole of the sleeve. After the adoption of the self-tightening and position-adjustable tailstock for the grinder, provided by the invention, a reciprocating movement of the sleeve is executed by the cylinder on the tail part of the device so as to drive a tip do the reciprocating movement to tighten and loose a workpiece; the cylinder instead of a manual wrenching handle is used as an executing component, so that the automatic control of equipment can be easily realized; and the self-tightening and position-adjustable tailstock for the grinder is provided with a hand wheel regulating device, so that the axial extension and retraction of the tailstock sleeve can be conveniently regulated.

Description

technical field [0001] The patent of the present invention relates to the tail stock used for top tightening at the tail of the grinding machine. Background technique [0002] The common grinding machine used for processing the rubber roller of laser printers uses the manual operation handle to tighten and loosen the tailstock of the workpiece when it is used for the tightening function of the workpiece. The function of the specific mechanism is: the sleeve is tightened by the compression spring, and the tip cooperates with the sleeve through the Morse taper, and the tip is used to tighten one end of the workpiece. The handle of the tailstock is connected with the sleeve through the lever, and when the handle is pulled at an angle, the sleeve can be moved back and forth by driving the lever, so as to realize the process of loosening and tightening the workpiece. [0003] The tailstock of an ordinary grinder does not have the function of adjusting the clamping range of the c...

AI Technical Summary

Problems solved by technology

[0003] The tailstock of an ordinary grinder does not have the function of adjusting the clamping range of the condition with the hand wheel. If the length of the workpiece changes, you must loosen the compression bolts between the tailstock and the worktable, and then move the tailstock to a suitable position and then lock it. Bolts require a lot of adjustment work, and the preparation time before processing is long, which is a waste of time and manpower

[0004] The jacking force of the ordinary tailstock is provided by a compression spring, and the jacking force cannot be adjusted. For the grinding of slender workpieces, excessive jacking force can easily cause the workpiece to bend and deform.

[0005] The existing grinding machine tailstock workpiece tightening and loosening action devices are all manually operated, which does not meet the requirements for automatic control;

[0006] The steps of adjusting the clamping range between the tailstock and its headstock on the existing grinder are cumbersome, and the length of the rubber roller of the printer varies according to the design requirements of different upstream manufacturers. Adjust the position according to the change to adapt to the appropriate tightening force;

[0007] The jacking force of the tailstock of ordinary grinders is guaranteed by the compression spring, and the jacking force is too large. When tightening the slender parts such as the rubber roller of the printer, it will often cause bending deformation, and the jacking force cannot be adjusted.
