Notching press positioning device for motor punching

Abstract

The invention discloses a notching press positioning device for a motor punching sheet, belongs to the technical field of notching presses, and aims to solve the problems that the stability of the motor punching sheet is reduced and normal notching is not facilitated due to the fact that the existing motor punching sheet and a placing table are easy to shift, and the positioning device cannot be used for positioning the motor punching sheet when the positioning device is used for fixing the motor punching sheet. The motor punching sheet is disc-shaped, so that the stability is low during fixing; through the underlay assembly, the transmission mechanism and the lifting assembly, the deck plate is connected with the underlay assembly, and the bottom box is connected with the transmission mechanism and the lifting assembly; according to the motor punching sheet triangular positioning device, a pressing block and a rubber air cushion are extruded, air in the rubber air cushion is extruded into a telescopic air pipe to enable the telescopic air pipe to extend, accordingly, an inserting rod moves and is inserted into a locking hole, triangular fixing of a to-be-machined motor punching sheet is achieved, a triangular positioning piece is not prone to loosening, and the working efficiency is improved. The stability of the to-be-processed motor punching sheet during processing is indirectly improved, and the processing quality is improved.

Description

technical field [0001] The invention relates to the technical field of punching machines, in particular to a punching machine positioning device for motor punching. Background technique [0002] The punching machine is a special equipment for single-slot punching for punching the slot holes of the motor rotor or stator silicon steel sheet. The die for punching the motor rotor or the stator silicon steel sheet is installed on the lower plane of the punch (ie, the slider). The eccentric crankshaft rotates to drive the punch to reciprocate up and down, and drive the upper die to reciprocate up and down. The silicon steel sheet (punching sheet) that needs to be punched is installed on the indexing device with intermittent motion, and the silicon steel sheet is rotated according to the requirements of the servo program through the indexing device. When the upper die moves downwards, the punching sheet does not rotate to punch the slot holes. When the upper die moves upwards and ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a punching machine positioning device for motor punching, which solves the problem that the current positioning device in the background technology is prone to displacement between the motor punching sheet and the placement table when the motor punching sheet is fixed. position phenomenon, resulting in a decrease in the stability of the motor punching, which is not conducive to the normal operation of the punching groove, and when the motor punching is fixed by the positioning device, because the motor punching is in the shape of a disc, the stability during fixing is low. Secondly, in the process of grooving, the waste chips generated are not conducive to collection. After working for a long time, there will be more waste chips on the surface of the table, which will affect the progress of the work.
