Drilling mechanism for automatic processing machine for erhu tuning pegs

Abstract

The invention discloses a drilling mechanism for an automatic processing machine for erhu tuning pegs. The mechanism comprises friction wheel equipment, drilling equipment and detection equipment; the friction wheel equipment comprises a friction wheel driving motor and a driving friction wheel; the drilling equipment comprises a drilling equipment mounting plate, two linear guide rails, a screw nut and a drilling equipment feeding motor are arranged on the drilling equipment mounting plate, the drilling equipment feeding motor can drive the screw nut to drive a support mounting seat to move on the two linear guide rails, and a bit driving motor provided with a bit is arranged on the support mounting seat through a bit driving motor support; and the detection equipment comprises a photoelectric reflection sensor fixed through a sensor support. With the mechanism, tuning peg blanks can be drilled automatically, manual operation is not required, and the labor intensity is low; angles of the tuning peg blanks can be detected and adjusted automatically, tuning peg planes are perpendicular to the bit, and the bit is prevented from being damaged; and the drilling depth can be controlled automatically, drilling actions are reliable, positions are accurate, and the precision is high.

Description

technical field [0001] The invention relates to a drilling mechanism controlled by PLC, which is used for punching pegs in the automatic processing of erhu pegs. 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 drilling operation of the erhu peg, because there is not a kind of drilling mechanism specially used for punching the erhu peg on the market, it is therefore basically all done by semi-mechanical and semi-manual at present. This backward erhu peg drilling method not only requires a large number of drillers, but also has high labor intensity and high processing cost, and it is difficult to guarantee the processing quality of the drilling, the processing consistency is poor, it is easy to scrap, and the processing efficiency is low.

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 drilling process of the erhu peg, because there is no special drilling mechanism for punching the erhu peg on the market, so it is basically completed by half-machine and half-manual at present.

This backward drilling method of erhu pegs not only requires a large number of drillers, but also has high labor intensity and high processing cost, and it is difficult to guarantee the processing quality of the drilling, the processing consistency is poor, it is easy to scrap, and the processing efficiency is low.
