Horizontal pushing type safety chuck

Abstract

The invention relates to a horizontal pushing type safety chuck, and belongs to the technical field of clamping equipment in the curling industry. The safety chuck comprises a guide shaft, a bearing assembly, a pushing disc assembly and a mounting flange, wherein the guide shaft is provided with a guide groove; the bearing assembly is provided with a clamping opening for bearing a rolling crankshaft, a clamping block slides into the clamping opening in the axial direction of the guide shaft along the guide groove to clamp the rolling crankshaft, and slides out of the clamping opening along theguide groove to open the clamping opening to place the to-be-clamped rolling crankshaft; the mounting flange is rotationally arranged on the guide shaft in a sleeving mode, and a first deviation piece is matched with a second deviation piece on the pushing disc assembly; when the guide shaft is rotated, relative rotation of the pushing disc assembly and the mounting flange is converted into translational sliding of the pushing disc assembly in the axial direction of the guide shaft, and the clamping block is guided to automatically reset to clamp the rolling crankshaft. The design and machining of the bearing assembly and the clamping block are particularly simple, the cost and the machining time are saved, and meanwhile, the placement depth of the rolling crankshaft cannot be influencedby a horizontal pushing type clamping mode.

Description

technical field [0001] The invention relates to the technical field of clamping equipment in the curling industry, in particular to a flat-push safety chuck. Background technique [0002] In the coiling industry, the clamping of the coiling shaft is generally to use the inclined push type safety chuck. Its working principle is: turn the safety chuck to the designated position, open the safety chuck by pushing it obliquely, put the coiled shaft with coiled material into the clamping mouth of the safety chuck, and then close the safety chuck manually or through the drive shaft Drive the winding shaft to rotate together to reset; when the coil material needs to be replaced, turn the safety chuck to the designated position again, open the safety chuck to replace the new shaft. [0003] There are following defects in this inclined push type safety chuck: [0004] 1. The safety chuck and the coiling shaft have certain matching requirements. When the inclined push type design is ...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the defects of the prior art, especially for the problem that the oblique push type design is difficult and affects the depth of the curling shaft, the present invention provides a flat push type safety chuck. The main body of the push plate drives the clamping block along the guide The guide groove of the shaft slides out or slides into the clamping opening, so as to place the coiling shaft or clamp the coiling shaft, the processing design is simple, and the insertion depth of the coiling shaft is not affected
