Mechanism for machining key grooves in blockage holes of printing plate rollers

Abstract

The invention relates to a mechanism for machining key grooves in blockage holes of printing plate rollers. The mechanism comprises a broaching machine, a broaching shaft, a broaching tool, a broaching machine connection shaft and a plate roller clamp. One end of the broaching tool is fixedly connected with the broaching shaft through the broaching machine connection shaft, and the other end of the broaching tool penetrates through the center of the plate roller clamp. A broaching tool traveling guide groove is formed in the center of the plate roller clamp. The broaching tool penetrates through the broaching tool traveling guide groove to make contact with plate roller workpieces to be machined. One end of the plate roller clamp is fixedly connected with the broaching machine, and a workbench and a baffle are arranged at the other end of the plate roller clamp. The workbench is located below the baffle. The plate roller workpieces are arranged on the workbench in the axial direction of the plate roller clamp. Limiting blocks are arranged between the plate roller workpieces. The baffle abuts against the top ends of the plate roller workpieces. One end of the piston rod is fixed to the lower surface of the workbench, and the other end of the piston rod is connected to the air cylinder. Compared with the prior art, by the adoption of the mechanism for machining the key grooves in the blockage holes of the printing plate rollers, key groove broaching can be conducted on the blockage holes of the multiple plate rollers at a time, the working efficiency is high, the machining precision is high, operation is easy, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of printing plate roller processing, and relates to a key groove processing mechanism, in particular to a key groove processing mechanism used for printing plate roller blocking holes. Background technique [0002] During the processing of printing plate rollers, each printing plate roller is equipped with keyways of different specifications due to the difference in printing equipment of customers. Usually, the keyway processing process of the printing plate roller is placed after the plug is welded, and the keyway is planed in the blocked hole of the processed plate roller with a planer. But can only process the keyway in one blocking hole at a time, the processing and loading and unloading time of a single keyway need four minutes, and the same printing plate roller needs to be processed twice, and this has just reduced working efficiency greatly. At the same time, the key planing process needs to be oper...

AI Technical Summary

Problems solved by technology

But only one keyway in the plug hole can be processed at a time, and the processing and loading and unloading time of a single keyway takes four minutes, and the same printing plate roller needs to be processed twice, which greatly reduces the work efficiency

At the same time, the key planing process needs to be operated by professional technicians, and the knives used for keyway processing are grinded by the technicians themselves, but because the technical proficiency of each technician is very different, this makes the grinding tool There is a large difference in precision, resulting in a large deviation in the depth and width of the processed keyway, and the uniformity of the keyway size is poor, which will directly affect the normal use of printing plate roller products and bring greater economic benefits to enterprises and customers. loss
