Description

A commutator sheet die

technical field

The invention belongs to the technical field of commutator manufacturing, and in particular relates to a commutator sheet-arranging die.

Background technique

The commutator is the main component in the motor, and it is mainly composed of an inner bush, a bakelite main body around the inner bush and a copper bar commutator segment arranged around the bakelite main body. When the commutator is manufactured, it is necessary to arrange the commutator pieces on the plastic core of the commutator on the commutator arranging machine. Insert the commutator piece to the designated position. Each time a commutator piece is inserted, the plastic core of the commutator must rotate a certain angle, and then insert the next piece of commutator piece until all the commutator pieces of the plastic core are inserted into the commutator piece. In the above series of processes, how to achieve accurate positioning of each step is the key to improving processing efficiency and reducing scrap rate.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the present invention provides a commutator sheet-arranging die.

The present invention is realized by the following technical solutions: a commutator sheet arranging die, including a frame, a turntable, and a guide block; the frame is formed by integrally connecting a seat shell, a connecting neck, and a limit platform from top to bottom; The limit platform is located above the turntable in a horizontally rotatable manner on the top of the seat shell; the limit platform is provided with a jack that penetrates up and down; a guide block is inserted into the jack. When working, the mold is installed on the tablet machine. Fix the plastic core of the chip arrangement in the center of the turntable, fine-tune the angle of the turntable so that the alignment block is aligned with the hole of the plastic core of the chip alignment up and down, and the head of the chip alignment machine carries the commutator piece from the center of the alignment block and inserts it into the plastic core of the alignment block, and Push down in place to complete the insertion of a commutator segment. Then the turntable rotates at a certain angle, and enters the next working cycle until the holes of the plastic core of the arrangement are fully inserted. Remove the plastic cores and replace them with new plastic cores.

Further, in the above-mentioned commutator chip arrangement mold, a vertical main shaft is fixed in the center of the turntable and extends downward into the seat shell; a worm gear is sleeved on the main shaft; the worm gear is meshed with the worm; The drive motor is preferably a servo motor, which can ensure the precision and controllability of the rotation of the turntable.

Further, in the above-mentioned commutator sheet-arranging die, the surface of the turntable is provided with a sunken circular sinking platform; the sinking platform is fixed with a group of upwardly convex positioning columns. The plastic core is inserted into the sinking table to ensure the accuracy of its position, and the positioning column is aligned with the hole on the plastic core body to ensure that the angle of each insertion is very accurate. Therefore, for the same type of chip-arranged plastic cores, only the angle calibration needs to be performed during the first chip-arrangement, thus greatly improving the work efficiency.

Preferably, in the above-mentioned commutator sheet arranging die, there are 4 positioning columns in total, which are distributed in a circular array around the center of the sinking platform.

Further, in the above-mentioned commutator sheet-arranging die, the guide block is composed of a panel, a clamping block, and a guide nozzle from top to bottom; the guide block is provided with guide holes up and down, and the upper end face of the guide hole is located in the panel range. , the lower end face of the guide hole is located within the range of the guide nozzle. When the guide block is matched with the limit platform, the panel is placed on the limit platform, and the clamping block is inserted into the jack, thereby ensuring the accurate position of the guide block. In addition, in order to adapt to different types of plastic cores, the corresponding guide block can be replaced to meet the requirements of use, so it has good versatility.

Preferably, in the above-mentioned commutator sheet arranging die, the guide hole is in the shape of a funnel, and the upper end face of the guide hole is located in the large and the lower end face is small.

Preferably, in the above-mentioned commutator sheet arranging die, the two sides of the socket are periodically arranged in a circular zigzag shape; the side surface of the clamping block matches the shape of the socket; the length of the socket is greater than the length of the clamping block. In this way, the guide block can be moved laterally by a fixed distance according to the positioning needs, while ensuring that the guide block will not be displaced due to vibration.

Beneficial effects: Compared with the prior art, the commutator chip arrangement die provided by the present invention has reasonable design, convenient operation, strong adaptability, can be accurately positioned in the film arrangement operation, significantly improves the work efficiency, and reduces the defective product rate .
