Mechanical tool for achieving different-angle grinding of multiple cutters at a time

Abstract

The invention provides a mechanical tool for achieving different-angle grinding of multiple cutters at a time and belongs to the technical field of grinding and polishing devices. The mechanical tool for achieving the different-angle grinding of the multiple cutters at a time comprises a base plate, supports, rotary shafts and rotary shaft angle adjusting mechanisms. The base plate is of a rectangular plate structure, and the supports are fixedly installed at two ends of the base plate. Shaft sleeves matched with rotary shafts in number are embedded into the supports, and the rotary shafts are installed in the shaft sleeves in a matched. Cutter supporting seats are arranged at the middle positions of the rotary shafts, rotor blades to be grinded are installed on the cutter supporting seats, and the installing positions of the rotor blades are limited through positioning plates. Each rotary shaft angle adjusting mechanism is installed at one end of the corresponding rotary shaft and is located on the outer sides of the supports. The mechanical tool is matched with a common vertical driller to achieve the function of achieving different-angle grinding of the multiple cutters at a time, shortens a cutter grinding period, reduces the maintenance cost, also ensures the consistency of the grinding sizes of the multiple cutters and further facilitates subsequent cutter installation and debugging works.

Description

technical field [0001] The invention relates to a tool grinding tool, in particular to a mechanical tool capable of grinding multiple tools at different angles at one time on an ordinary vertical grinder, and belongs to the technical field of grinding and polishing equipment. Background technique [0002] The first-level shredder and the second-level shredder are the core components of the equipment. Among them, the second-level shredder directly affects the working efficiency of the shredder. The ability of the second-level shredder to destroy paper is 150 kg / Hour. Due to the high-speed operation of the secondary shredder, the high utilization rate and easy wear and tear, it needs to be repaired after about 80 hours of paper cutting (about 20 working days in normal operation). [0003] The secondary crushing knife of the banknote shredder is a rotor knife structure, including a group of rotor blades uniformly arranged along the circumferential direction (the structure of ...

AI Technical Summary

Problems solved by technology

[0003] The secondary crushing knife of the banknote shredder is a rotor knife structure, including a group of rotor blades uniformly arranged along the circumferential direction (the structure of the rotor blades is shown in the attached figure 1 As shown), in view of the problem of grinding the edge 1-1 of the rotor blade 1 of the secondary shredder in the banknote shredder, if the conventional grinding method is used to grind each rotor blade edge separately, not only the work efficiency is low, but the Moreover, it is difficult to ensure the consistency of the tool grinding angle, which is not conducive to the subsequent tool installation and debugging work; if the tool group is repaired by returning to the original factory for repair, there are defects such as long maintenance period and high maintenance cost
