Protector automatic assembly device with rivet spinning riveting function

Abstract

An automatic assembly device having a rivet spinning riveting function and used for protectors comprises a workbench, a rotary disk, a rotary disk driving mechanism, a retained workpiece detection mechanism, a rivet mounting mechanism, a protector base extracting and releasing mechanism, a workpiece absence detection mechanism, a static contact mounting mechanism, a rivet spinning riveting mechanism, a movable contact extracting and releasing mechanism, a movable contact prepressing mechanism, a movable contact compressing mechanism, an inserting piece extracting and releasing mechanism, an inserting piece press-fixing mechanism and a protector removing mechanism. The automatic assembly device is characterized in that the rivet spinning riveting mechanism comprises a spinning head driving reduction gearbox cantilever support fixing column, a spinning head driving motor, a spinning head driving reduction gearbox, a spinning head, a press block lifting cylinder, a press block left limiting seat, a press block right limiting seat, a static contact press block and a pair of cylinder column fixing bracket guide rods. The automatic assembly device has the advantages that labor resources are saved, the operating intensity is reduced, the assembly efficiency is increased, the assembly quality is guaranteed, and the requirement for industrial mass production of refrigeration compressor motor protectors can be met.

Description

technical field [0001] The invention belongs to the technical field of automatic installation equipment for electronic and electrical products, and in particular relates to an automatic assembly device for a protector with the function of spinning and riveting rivets. Background technique [0002] The aforementioned protector is the motor protector of the refrigeration compressor. The function of the motor protector of the refrigeration compressor is to provide effective protection for the temperature and overload of the motor of the refrigeration compressor. Its structure can be found in the "single-phase Overload protector for AC motor", this structure of refrigeration compressor motor protector and refrigeration compressor motor starter can be reasonably combined to form a "refrigeration compressor motor starter, protector", such as CN2606490Y (motor starter protector) , CN2606491Y (integrated motor starter and protector), CN102386815B (integrated motor starter and protec...

AI Technical Summary

Problems solved by technology

However, in the actual automatic installation process, the aforementioned static contacts need to be riveted to the protector base by rivets. However, because the material of the protector base is usually plastic, and because the overall volume or size of the protector base is relatively small Small, and because the volume of the rivet is significantly smaller than that of the dynamic and static contact pieces and the insert piece, if the rivet is used to rivet the static contact piece and the protector base by stamping, then it will be damaged under the impact force of the stamping. Damage to the base of the protector, such as cracks or even overall cracking
