Commutator mica sheet and copper sheet mixed arrangement device

Abstract

A commutator mica sheet and copper sheet mixed arrangement device comprises a base, a sheet arrangement mold assembly, and a mold driving assembly. The mold body of the sheet arrangement mold assembly is internally sleeved with sheet inserting molds, and the front ends of the sheet inserting molds are each equipped with a copper sheet blocking column. A mica sheet slot is formed between every two adjacent copper sheet blocking columns. The inside of the sheet inserting molds is coaxially sleeved with a bracket mold, and a bracket blocking column is formed at the front end of the bracket mold. For sheet arrangement, mica sheets are inserted into the mica sheet slots first, and then, copper sheets are aligned with the copper sheet blocking columns, the copper sheets are pushed so as to push the sheet inserting molds to retract into mold cavity holes, and finally, the mica sheets are each clamped between two copper sheets. For sheet inserting, inserted sheets are pushed so as to push the bracket mold to retract, and sheet inserting is completed. The production efficiency is high, the yield of processing is improved, and the degree of automation of commutator sheet inserting production can be improved.

Description

technical field [0001] The invention relates to the technical field of automatic inserting machines, in particular to a commutator mica sheet and copper sheet mixed sheet arranging device. Background technique [0002] The commutator is a common accessory on the motor. The basic structure of the commutator is a ring surrounded by a plurality of contact pieces (also called copper pieces), which are respectively connected to each contact on the rotor. The two connected outside are called brushes, and only one of them is in contact with it. In order to ensure that the copper sheets are insulated from each other during production and assembly, when the copper sheets and bakelite powder are die-cast, mica sheets need to be inserted between each adjacent two copper sheets at intervals, and the copper sheets and the The mica sheet is inserted into the insert bracket as a transition process. [0003] The traditional commutator copper sheets are inserted in the copper sheet slots o...

AI Technical Summary

Problems solved by technology

[0003] The traditional commutator copper sheets are inserted into the copper sheet slots of the insert brackets, and the mica sheets are inserted between adjacent copper sheets, all of which are manually inserted one by one; manual assembly is used, and its production efficiency is very high. Low, high labor intensity, and the mica sheet is thin and brittle, it is easy to cause it to break when inserted, and the good rate of plugging is not high, which can no longer meet the needs of modern large-scale production
