Self-protected structure for rapidly fixing hydraulic tailstock and rejecting tip

Abstract

The invention discloses a self-protected structure for rapidly fixing a hydraulic tailstock and rejecting a tip. The self-protected structure for rapidly fixing the hydraulic tailstock and rejecting the tip comprises a tailstock body, a shaft sleeve, a mandrel, the tip, a push rod and a handle, wherein the mandrel comprises a front shaft and a rear shaft, the shaft sleeve is arranged inside the tailstock body, the mandrel is arranged inside the shaft sleeve, and the tip and the push rod are arranged in the middle of the mandrel; a bumper block is arranged at the front end of the push rod which is further provided with a front guide disk and a spring, and the handle is arranged on the tail portion of the tailstock body. According to the self-protected structure for rapidly fixing the hydraulic tailstock and rejecting the tip, the structure is simple, and the operation is convenient; the handle is additionally arranged to push the push rod, the push rod can push out the tip easily, and the push rod can reset automatically by means of the design of the spring on tail portion of the push rod; meanwhile, the bumper block is arranged on one end of the push rod, noise caused by collision of the push rod and the tip can be effectively reduced, the friction between the push rod and the tip can be reduced, and a good protective effect on the surfaces of the push rod and the tip is achieved; therefore, demands of current markets are better met.

Description

technical field [0001] The invention relates to a top structure, in particular to a fast fixed hydraulic tailstock retracting top structure with self-protection. Background technique [0002] With the rapid development of modern society, the upgrading of new products and new technologies is also gradually accelerating, thus putting forward higher requirements for the variety, machining accuracy and efficiency of machine tools. In today's world, all countries attach great importance to the machine tool industry, and are competing to develop mechatronics, high-quality, high-precision, and high-efficiency automated machine tools to accelerate the development of their own industries and national economies. The tailstock structure is an important part of the CNC machine tool, which directly affects the operation of the entire machine tool. [0003] The existing tailstock structure on the market has a relatively complicated structure, and most of them use the push rod to directly...

AI Technical Summary

Problems solved by technology

[0003] The existing tailstock structure on the market has a relatively complicated structure, and most of them use the push rod to directly hit the tip to withdraw the tip, which will not only cause damage to the surface of the tip, but also generate relatively large noise, and it will be in a noisy working environment for a long time , will have a certain degree of impact on the physical and mental health of employees. At the same time, although the existing tailstock structure can withdraw the top during use, its push rod cannot automatically retreat, so its operation is too It is cumbersome and seriously affects the efficiency of production, so the existing tailstock structure cannot really meet the needs of the current market
