Description

Technical Field

[0001] The utility model belongs to the technical field of nylon wheel processing, in particular to a tooling fixture for a nylon wheel. Background Art

[0002] Nylon wheels are pulleys made of nylon plastic. They have good wear resistance, acid and alkali resistance, chemical stability, mechanical strength and light weight. They are widely used in the industrial field in mechanical transmission devices and tire manufacturing industries.

[0003] At present, the Chinese utility model with publication number: CN207077208U discloses a nylon wheel fixture, including: a fixed fixture and a movable fixture, the fixed fixture and the movable fixture are in the shape of a disc, the inner surface of the fixed fixture is evenly distributed with a plurality of first bosses, the first bosses are provided with positioning pins, the inner surface of the movable fixture is evenly distributed with a plurality of second bosses, the second bosses are provided with positioning holes corresponding to the positioning pins and passing through the movable fixture. The nylon wheel fixture of the utility model can ensure that the nylon wheel is not subjected to radial and axial external forces during machining and clamping, ensure the dimensional stability and consistency of the nylon wheel before and after processing, and finally ensure the dimensional accuracy of the nylon wheel.

[0004] In the existing nylon wheel processing process, tooling and clamps are required to fix the nylon wheels. However, since the factory will process different types of nylon wheels, it is necessary to replace different types of tooling and clamps according to the nylon wheel model, which affects the processing efficiency of the nylon wheel. At the same time, since the nylon material has a certain elasticity, the nylon wheel is easily deformed laterally when it is subjected to force processing. After the clamping process, the nylon wheel unloads the force and returns to its original shape, which will cause the concentricity of the processing to change, and the original processing size cannot be guaranteed, and the yield rate of the produced nylon wheels is low.

[0014] The utility model is further configured as follows: a gasket is bonded to one side of the extrusion plate away from the sliding ring.

[0015] By adopting the above technical solution, the friction between the contact surfaces on both sides of the extrusion plate and the nylon wheel is improved.

[0016] The utility model is further configured as follows: a protective net is provided on one side of the jacking plate close to the surface of the central axis.
