Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic clutch assembly, in particular to a clamp tool for electromagnetic clutch assembly. Background Art

[0002] The electromagnetic clutch is a friction clutch that generates a clamping force through electromagnetic force. It controls the clutch of the mechanical transmission device through electromagnetic force and electrostatic force, and can transmit power over a long distance. When assembling the electromagnetic clutch, the electromagnetic clutch housing needs to be fixed, and the stator is placed in a predetermined position of the housing. The stator usually has an electromagnetic coil, and the rotor is then placed opposite the stator. A certain gap is usually maintained between the two, and the friction plate group is installed on the rotor or stator.

[0003] After searching, it was found that a Chinese patent with publication number CN218425723U published a fixture for electromagnetic clutch production. This document can limit and fix the end cover of the electromagnetic clutch. However, when assembling the electromagnetic clutch, the electromagnetic clutch housing needs to be fixed. The electromagnetic clutch housing is generally annular. The existing fixture uses a clamping groove for fixing. Such a design is difficult to adapt to the curved surface characteristics of the annular housing. The operator needs to spend more time and energy to adjust and fix the position of the housing during the assembly process, resulting in low assembly efficiency. In view of this, a fixture for electromagnetic clutch assembly is designed. Utility Model Content

[0009] Furthermore, a plurality of penetrating strip grooves are equidistantly formed on the top of the positioning box in a circumferential manner, and the outer surface of the connecting rod is slidably connected to the inner side wall of the strip groove.

[0010] Furthermore, one end of the thrust spring abuts against the sliding block, and the other end of the thrust spring abuts against the inner wall of the fixing frame.

[0011] Furthermore, guide grooves are provided on both the front and rear sides of the fixing frame, and both the front and rear sides of the sliding block are fixedly connected with limit rods, and the outer surface of the limit rod is slidably connected to the inside of the guide grooves.
