Description

Technical Field

[0001] The present invention relates to the technical field of electrical and mechanical equipment, and particularly to a quick coupling mechanism for a expanding shaft. Background Art

[0002] In a stator production line, a quick coupling mechanism for an expanding shaft is commonly used to complete functions such as mold installation and opening / closing. The existing expanding shaft coupling mechanism uses threaded connections, which are complex in installation and disassembly, time-consuming for mold replacement, and require high adjustment accuracy, affecting the stability of mold opening and closing. Therefore, the existing expanding shaft coupling mechanism has disadvantages such as inconvenient operation and long mold replacement time. Summary of the Invention

[0003] The object of the present invention is to propose a quick coupling mechanism for an expanding shaft to solve the above technical problems.

[0004] The technical solution of the present invention is: a quick coupling mechanism for an expanding shaft, characterized in that: it is provided with a connecting shaft, a power source, a locking plate, and an expanding shaft. The connecting shaft is provided at the lower end of the output shaft of the power source. The connecting shaft is provided with a slot for slidably inserting the locking plate. The bottom of the locking plate is provided with a tapered hole, and a spring pin is provided at the corresponding position of the connecting shaft for positioning. An annular groove is provided at the upper end of the expanding shaft, and large and small waist-shaped holes are respectively provided at the corresponding positions of the locking plate for loosening and coupling cooperation, having the advantages of simple structure, convenient adjustment, reliable action, and quick mold replacement.
