Cutting mechanism for automatic processing machine for Erhu tuning peg

Abstract

The invention discloses a cutting mechanism for an automatic processing machine for an Erhu tuning peg. The mechanism comprises a clamping device and a sawing device; the clamping device comprises a gas claw support mounted on two small linear guide rails; a gas claw controlled by a gas claw loosening and tightening cylinder is arranged on the gas claw support; the gas claw support is connected with a gas claw telescoping cylinder; the sawing device comprises a saw blade cutter support mounted on two large linear guide rails; a saw blade cutter driving motor is arranged at the back part of the saw blade cutter support; a saw blade cutter is arranged at the front part of the saw blade cutter support; the saw blade cutter driving motor controls the saw blade cutter through belt transmission; a screw nut is arranged between the two large linear guide rails; one end of the screw nut is connected with a sawing device feeding motor; and the bottom of the saw blade cutter support is connected with the screw nut. With the mechanism, the processed tuning peg located on an index plate can be clamped automatically, the cut tuning peg can be moved out of the cutting station, the cutting action can be controlled automatically, the mechanism is not required to be operated by persons, the labor intensity is low, the cutting action is reliable, and the precision of the tuning peg in the length direction is high.

Description

technical field [0001] The invention relates to a cutting mechanism controlled by PLC, which is used for the cutting process of the peg in the automatic processing of the erhu peg. 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 cutting process of the erhu peg, because there is not a kind of grinding mechanism that is specially used to cut off the redundant part of the erhu peg on the market, so it is basically done by semi-mechanical and semi-manual at present. This backward grinding method of the peripheral surface of the erhu peg 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 processing quality of the peg, the processing consistency is poor, it is ...

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 the cutting process of the erhu peg, since there is no special grinding mechanism on the market for cutting off the excess part of the erhu peg, it is basically done by half-machine and half-manual.

This backward grinding method of the peripheral surface of the erhu peg 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 processing quality of the peg, the processing consistency is poor, it is easy to scrap, and the processing efficiency is low.
