Magnetic shoe press-fitting clamp for motor stator

Abstract

The invention discloses a magnetic shoe press-fitting clamp for a motor stator. The clamp comprises a supporting plate; a supporting screw rod is in threaded connection with the lower end of the supporting plat; the upper end of the supporting plate is connected with a base plate and a shell locating block by cylindrical locating pins; the shell locating block is fixedly connected with a motor shell; a T-shaped magnetic shoe locating bracket is clamped between the shell locating block and the base plate; a locating sleeve extending into the shell locating block and the motor shell is arranged at the upper part of the magnetic shoe locating bracket; thus, a lug boss for the motor shell to limit a magnetic shoe can be saved; waterproofness and airtightness of a motor product can be improved; moreover, good-looking appearance is realized; various dimensional requirements of the motor stator are easily guaranteed; high production efficiency is realized; during a magnetic shoe press-fitting process, breaking of the magnetic shoe is hard to cause; magnetic shoe glue can be filled just after the overall process is finished.

Description

technical field [0001] The invention relates to the field of press-fitting of motor stators, in particular to a jig for press-fitting magnetic tiles of motor stators. Background technique [0002] At present, in the press-fitting process of the stator magnetic tile of the wiper motor, the magnetic tile is made of iron epoxy Y32, the length is 32mm, the arch height is 12.5mm, the thickness is 4.8mm, and the width is 34mm. The magnetic tile clamp adopts 65Mn steel wire bending U-shaped Shape, diameter Φ2mm, after pressing the stator magnetic tile, ensure that the distance between the end face of the magnetic tile and the end of the casing: 19.5mm, the magnetic tile fits the inner wall of the casing, and the size of the opening is consistent with the bottom. Disadvantages of traditional tooling and fixtures: Firstly, two magnetic tile limit bosses are required to be punched with a punch at the bottom of the motor housing; the magnetic tile glue is coated with A and B glue by ha...

Problems solved by technology

Disadvantages of traditional tooling and fixtures: firstly, two magnetic tile limit bosses are required to be punched on the bottom of the motor casing; the magnetic tile glue is coated with A and B glue by hand, and then the magnetic tile is gently glued into the motor casing wall, it is not easy to ensure the consistency of the size of the bottom and the port, the adhesion is uneven, and it is easy to cause the armature to touch the magnetic tile during the action; the production efficiency is low, and the size is not easy to guarantee
