Description

Technical Field

[0001] The utility model belongs to the technical field of processing fixture equipment, in particular to a forged wheel hub processing fixture. Background Art

[0002] With the development of society and the popularization of automobiles, automobile wheels, as an indispensable part of automobiles, are divided into two production methods during the production process: forged wheels and cast wheels. The performance of forged wheels is better than that of cast wheels, but in the production process of forged wheels, the wheels need to be clamped and fixed for processing, which requires the use of a forged wheel processing fixture.

[0003] A Chinese patent application with authorization announcement number CN219930194U discloses an adjustable clamp for heat treatment of forged wheel hubs, including a wheel hub support disc, four cylinder guide column sleeves and a center positioning guide column sleeve, an electromagnetic control valve connected to the tail end of the center positioning guide column sleeve is arranged in the middle of the bottom end of the wheel hub support disc, a pneumatic sliding slider is movably installed inside the center positioning guide column sleeve, a smooth connecting rod slidably connected to the center positioning guide column sleeve is arranged at one end of the pneumatic sliding slider, and a wheel hub limiting pressure plate is fixedly arranged at one end of the smooth connecting rod. The utility model arranges a center positioning guide column sleeve and four cylinder guide column sleeves on the wheel hub support disc, and controls the air source through the electromagnetic control valve and the electromagnetic valve, so as to conveniently control the height of the wheel hub limiting pressure plate and the opening degree of the pneumatic limiting rod, so as to better clamp forged wheel hubs of different sizes, and arranges an undercut connecting plate and an extension strip, which helps to ensure the firmness and comprehensiveness of clamping and is easy to use.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned adjustable fixture for heat treatment of forged wheel hubs will cause different wheel hubs, which will result in different wheel rim sizes. The center positioning guide column sleeve will cause subsequent shaking problems when it is used for wheel rims of different sizes.

[0006] 2. When the adjustable clamp for heat treatment of forged wheel hub is put on the center positioning guide post sleeve, the extended pressure strip will cause inconvenience in putting on the wheel hub.

[0007] To this end, we provide a forged wheel hub processing fixture to solve the above-mentioned problems. Utility Model Content

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0034] Specifically, the outer wall of the fixed column 201 of the fixed component 2 is installed in a circular shape with the fixed high temperature spring 202 to fully fix and clamp the inside of the wheel rim, and the outer wall of the fixed column 201 is fixedly connected to the fixed high temperature spring 202 to fix the fixed high temperature spring 202 to avoid shaking of the fixed high temperature spring 202, and the moving end of the fixed high temperature spring 202 is fixedly connected to the fixed plate 203, and the fixed plate 203 has a fixing effect.

[0035] Furthermore, the upper side wall of the fixing seat 1 is fixedly connected to the fixing column 201 to fix the fixing column 201, which is convenient for fixing the wheel hub, and the lower side wall of the fixing plate 203 is slidably connected to the fixing seat 1 to facilitate the movement of the fixing plate 203, so as to better fix the wheel hub.

[0036] The operation process of this embodiment is: the fixing plate 203 is contracted toward the inner circle, and then the fixed high-temperature spring 202 is contracted, so as to change the space occupied by the fixing column 201 and the outer wall of the fixing plate 203, so as to facilitate the wheel rim of the hub to be put on the fixing column 201. After loosening the fixing plate 203, the fixed high-temperature spring rebounds 202, which will cause the fixing plate 203 to expand outward to adapt to wheel rims of different sizes, so as to effectively fix the wheel hub and avoid subsequent shaking. Specific embodiment 2

[0038] See also Figure 1 , Figure 2 and Figure 4 On the basis of the first specific embodiment, a limiting assembly 3 is installed on the upper side wall of the fixing seat 1.
