A Clamping and Indexing Mechanism for Erhu Tuddle Automatic Processing Machine

Abstract

The invention discloses a clamping indexing mechanism used for an automatic machining machine of an erhu tuning peg. The clamping indexing mechanism comprises an indexing plate arranged on a machining table-board, and the lower end of a rotary shaft of the indexing plate is connected with a stepping electric motor; four sets of clamping devices are arranged on the upper plate of the indexing plate, and each clamping device is composed of the following components such as a fast clamping head, a fast clamping head pressing rod, a spring, a connecting screw and a pressing head; four sets of rotating plate devices are arranged on the lower plate of the indexing plate, and each rotating plate device is composed of the following components such as a tuning peg rotating plate, a locating pin, a friction driven wheel, a connecting shaft device driven wheel and a photoelectric sensor; and the four sets of clamping devices are in one-to-one correspondence with the four sets of rotating plate devices, and four stations capable of rotating by turns are formed. According to the clamping indexing mechanism, automatic indexing of machining of the erhu tuning peg is achieved, and the four stations can conduct continuous automatic machining; the fast clamping heads are used as the clamping devices, clamping is reliable, efficiency is high, and labor intensity is low; and because of the rotating plate devices and the photoelectric sensors, when a tuning peg workblank is clamped, clamping is more reliable and not prone to making mistakes.

Description

Technical field [0001] The invention relates to a clamping and indexing mechanism controlled by a PLC, which is used for the clamping and automatic indexing of the pegs when the pegs of the erhu are automatically processed. Background technique [0002] The existing erhu peg processing is basically a single-process manual operation, such as the grinding, drilling and cutting of the pegs. These processes must be completed one by one manually and cannot be indexed. This processing method is not only inefficient in processing , Poor product consistency, high labor intensity, and high processing cost. [0003] Although there are some indexing mechanisms for processing in the market today, these indexing mechanisms are not specifically used to process erhu pegs. These indexing mechanisms neither have a clamping device for clamping the pegs nor a sensor for detecting whether there is a peg on the station. Therefore, not only the pegs to be processed cannot be effectively fixed on this ...

AI Technical Summary

Problems solved by technology

Therefore, not only the peg to be processed cannot be effectively fixed on this type of mechanism, but also the presence or absence of the peg on the station is entirely judged by humans, which is very error-prone and difficult to guarantee the processing quality
