Trimming machine for end faces of pins

Abstract

The invention discloses a trimming machine for the end faces of pins. The trimming machine comprises a machine table, a graphite pin feeding device arranged on the machine table, a first feeding guide trough, a second feeding guide trough, a polishing device, a receiving disc and a linear pushing device. The first feeding guide trough and the second feeding guide trough are arranged on the machine table. The first end of the second feeding guide trough is in butt joint with the second end of the first feeding guide trough. The polishing device is arranged above the second end of the second feeding guide trough. The receiving disc is arranged on the machine table. The linear pushing device is arranged on the outer side of the first end of the second feeding guide trough. A conductive block electrically connected with a driving switch of the linear pushing device is arranged on the inner side wall and the inner bottom wall of the first end of the second feeding guide trough. According to the trimming machine, through connection achieved when the graphite pins are in contact with the conductive block and disconnection achieved when the graphite pins are not in contact with the conductive block, the pushing end of the linear pushing device is driven to push the graphite pins on the second feeding guide trough to forwards move, and then the aim of polishing the graphite pins is achieved. The whole working process is full automatic, manual polishing is avoided, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a graphite boat accessory processing device, in particular to a pin end face trimming machine. Background technique [0002] The stop pins for graphite boats are generally made of graphite materials. After lathe processing, there are redundant and unremoved protruding parts at the tail. This protruding part will affect the normal use of the stop pins, so the protruding parts must be removed. , to ensure that the end face of the stop pin is flat. The current way to remove such protruding parts is to remove them one by one by hand with a spatula, but this removal method is time-consuming and laborious, and reduces production efficiency. [0003] And also there is not a kind of device that can remove the protruding part of the stop pin end quickly at present. Contents of the invention [0004] The object of the present invention is to address the deficiencies and defects of the prior art and provide a pin end face trimmer, whi...
