Abstract

The invention relates to the field of machining equipment, in particular to a grinding machine tail seat structure. The grinding machine tail seat structure comprises a casing, a sleeve and a center, wherein the sleeve is arranged in the casing, the center is arranged at one end of the sleeve, the tail part of the casing is provided with a rotating shaft, a shaft sleeve linked with the rotating shaft is connected onto the rotating shaft in a sleeving way, the grinding machine tail seat structure also comprises a shifting rod, one end of the shifting rod is fixedly arranged at the shaft sleeve, the other end of the shifting rod is fixedly arranged at the sleeve, a handle is also arranged on the rotating shaft, the tail part of the casing is provided with a lead screw, one end of the lead screw is embedded into the casing and is connected with the other end of the sleeve, the other end of the lead screw is arranged at the outside of the casing and is connected with the handle, a screw nut and a spring are connected onto the lead screw in a sleeving way, the screw nut is fixedly arranged on the casing through a pin element, one end of the spring is fixedly arranged at the screw nut, and the other end of the spring is fixedly arranged at the lead screw. The grinding machine tail seat structure adopting the technical scheme has the advantage that the pre-tightening force can be automatically adjusted.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a grinder tailstock structure. Background technique [0002] The tailstock of the grinding machine mainly uses the tip installed on the tailstock and the tip of the grinding machine headstock to support the workpiece together, so as to realize the accurate positioning of the workpiece. When grinding, the tailstock is fastened on the inclined surface of the workbench with L-shaped screws. [0003] One of the biggest problems in the existing tailstock is that the pretightening force of the tailstock tip to the workpiece cannot be automatically adjusted. Since the workpiece will elongate due to thermal expansion during the grinding process, and the preload of the tip is fixed at this time, it is easy to cause bending deformation of the workpiece and excessive wear of the tip. Contents of the invention [0004] The invention aims to provide a grinder tail stock structure which ...
