A Grinding Mechanism for Erhu Tuddle Automatic Processing Machine

Abstract

The invention discloses a grinding mechanism applied to an automatic processing machine of an erhu tuning peg. The grinding mechanism is composed of a grinding device and a connecting shaft device, wherein the connecting shaft device comprises a connecting rod, a tuning peg blank rotary drive motor is connected to the bottom end, a drive air cylinder of the connecting shaft device is connected to the lower part, and a driving wheel of the connecting shaft device is disposed on the top end; and the grinding device comprises a grinding device slide plate which is driven by a grinding head feeding motor, a grinding head drive motor is disposed on the lower surface of the grinding device slide plate, and the grinding head drive motor is transmitted by a belt and connected to a shaped grinding head. According to the invention, the shaped grinding head can automatically enter or leave a grinding station during grinding, and a linear displacement sensor is disposed to control a grinding size, so automatic grinding is achieved, manual operations are not needed, and labor strength is low; and grinding actions are reliable, and the circular face of the processed tuning peg has high accuracy. According to the invention, a protective cover is disposed on the shaped grinding head; an air draft device is connected to the end; and wood bits generated during the grinding can be absorbed during grinding processing, so healthy and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to a grinding mechanism controlled by PLC, which is used for grinding the peripheral surface of the peg when the erhu peg is automatically processed. Background technique [0002] The existing erhu peg processing is basically a single-process manual operation, such as the grinding, punching and cutting of the peg. These processes not only cannot be indexed, but must all be completed manually one by one. [0003] Especially the grinding process of the erhu peg, because there is not a kind of grinding mechanism specially used for grinding the peripheral surface of the erhu peg on the market, so it is basically completed by semi-mechanical and semi-manual at present. This backward grinding method of the peripheral surface of the peg shaft not only requires a large number of operators, but also has high labor intensity and high processing cost, and it is difficult to guarantee the grinding quality of the peripheral surface of the peg ...

Problems solved by technology

[0002] The existing erhu peg processing is basically a single-process manual operation, such as peg grinding, punching and cutting. These processes cannot be indexed, and must be completed manually one by one.

[0003] Especially for the grinding process of the erhu peg, since there is no special grinding mechanism on the market for grinding the peripheral surface of the erhu peg, it is basically completed by half-machine and half-manual.

This backward grinding method of the peripheral surface of the peg shaft not only requires a large number of operators, but also has high labor intensity and high processing cost, and it is difficult to guarantee the grinding quality of the peripheral surface of the peg shaft, the processing consistency is poor, it is easy to scrap, and the processing efficiency is low.

In addition, a large amount of wood chips will be produced in the grinding process. If these wood chips are scattered in the workshop for a long time, it will not only pollute the environment, but also cause harm to the health of the workers.
