Description

Technical Field

[0001] The invention relates to the technical field of positioning fixtures for motor production and assembly, and in particular to a positioning fixture for motor production and assembly. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. When the motor is assembled at the end cover, the housing needs to be positioned and clamped.

[0003] A motor refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, the generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electric energy. The present invention relates to a positioning fixture for motor production and assembly.

[0004] Patent No.: CN210704504U discloses a positioning fixture for motor production and assembly. The positioning mechanism of this design includes a pneumatic push rod, a clamping block, and a transmission screw. The limit plate for fixing the motor seat is placed in the middle of the mounting table surface. When in use, the transmission screw is driven to rotate by an external motor to move the clamping block to one side of the motor seat using a slide rail under the action of the distance adjustment plate. The extension and retraction of the pneumatic push rod drives the clamping block to deflect to limit the position of the motor seat. The motor drives the transmission screw to rotate to achieve rapid movement of the distance adjustment plate position and the pneumatic push rod is used to push the clamping block to deflect to achieve clamping and quick disengagement operations. This can effectively reduce the overall debugging time of the clamping operation during assembly, meet the needs of multiple positioning and clamping operations during one assembly, and has a good use effect.

[0005] However, the above patent still has the following shortcomings: the above design is not convenient for clamping the motor assembly, and the motor is clamped directly by using clamps on both sides.
