Device for sticking magnetic steel in casing

Abstract

The invention aims to provide a device for sticking a magnetic steel in a casing, which can prevent the magnetic steel from deviating so as to enable the assembly position of the magnetic steel to bemore accurate. In order to achieve the purpose, the invention adopts the following technical scheme: the auxiliary device for sticking a magnetic steel in a casing comprises a plurality of movable blocks; the plurality of movable blocks are annularly arranged at intervals; the movable block is fixed at the output end of a driving mechanism; the casing is arranged on the circumferential outer sideof the movable block in a sleeving mode and supported on a first supporting table; the movable blocks move towards the inner wall side of the casing under the action of the driving mechanism; the lower ends of the movable blocks extend outwards in the circumferential direction to form second supporting tables used for supporting the magnetic steel; the distance between the circumferential outer edge of the second supporting table and the circumferential outer walls of the movable block is smaller than the thickness of the magnetic steel; two check blocks are arranged on the circumferential outer wall of each movable block; the movable blocks are located on the upper side of the second supporting table, and the shape of the outer wall, located between the two check blocks, of each movable block is the same as that of the inner wall of the magnetic steel.

Description

technical field [0001] The invention relates to a magnetic steel sticking device in a casing. Background technique [0002] During the assembly of the motor, it is necessary to fix the magnetic steel on the inner wall of the casing. The magnetic steel is tile-shaped and fixed on the inner wall of the casing by glue. Due to the interaction between the magnets, the magnets will deviate from the set position, so that the quality of the motor will be deteriorated. [0003] Some motors have a certain angle requirement between the casing and the magnetic steel. There is usually a process hole on the casing of this type of motor (as a drainage hole, or as a lubricating oil injection hole), and the angle between the process hole and the magnetic steel needs to be determined. The position is now drawn with a pen on the inner wall of the magnetic steel, and then the edge of the magnetic steel is attached to the pen mark. The assembly accuracy of the magnetic steel is low, and the qua...
