Description

Technical Field

[0001] This utility model relates to the field of automotive parts spraying tooling technology, and in particular to a spraying tooling for an aluminum alloy wheel hub anti-detachment ring. Background Technology

[0002] With increasing attention being paid to aluminum alloy wheels with anti-slip ring structures, the demand for such wheels is growing. However, due to the small demand and the fact that the anti-slip ring structure itself makes it impossible to automate the painting process, traditional anti-slip ring manufacturing often relies on manual painting, which is extremely inefficient, inconsistent, and significantly increases production costs. There is an urgent need to solve this problem.

[0003] Therefore, a spraying fixture for anti-detachment rings on aluminum alloy wheels is needed, which eliminates manual spraying, meets the requirements of the anti-detachment ring spraying process, has a simple structure, is adjustable, easy to operate, and can be reused, thereby reducing the production cost of wheels. Utility Model Content

[0004] The purpose of this invention is to provide a spraying fixture for anti-detachment rings on aluminum alloy wheels. This fixture replaces the original manual spraying process, improving the low efficiency of existing anti-detachment ring spraying on aluminum alloy wheels and thus greatly reducing the production cost of the wheels.

[0005] This utility model is implemented as follows:

[0006] A spraying fixture for an aluminum alloy wheel hub anti-detachment ring includes a bushing, a support beam, a locating pin, and a nut. The bushing is cylindrical and has a groove, an outer recess, and an inner recess. The support beam has a through hole, a support beam cap, a mating surface, a rod body, and threads. The locating pin has a locating head and a locating rod. The anti-detachment ring has a stepped hole.

[0007] During assembly, first place the support beam into the groove of the bushing, then place the support beam cap on the support beam into the inner recess of the bushing. The mating surface of the support beam should fit against the bottom surface of the inner recess of the bushing. Then, connect the support beam and the bushing together with the nut, ensuring that the axis of the central hole of the bushing is aligned with the central axis of the through hole of the support beam.

[0008] Furthermore, the outer and inner recesses of the bushing are coaxial, and the axes of multiple recesses are on the same plane.

[0009] Furthermore, the thread of the support beam and the diameter of the rod body are clearance fit with the groove of the bushing, with a clearance of 0.5-2mm.

[0010] Furthermore, the diameter of the support beam cap is larger than the width of the groove on the bushing to prevent the support beam from falling off.

[0011] Furthermore, the length of the rod body on the support beam is less than the wall thickness D of the bushing, while the total length L of the thread length on the support beam and the rod body length is greater than the wall thickness D of the bushing, ensuring that the nut can be tightened.

[0012] Furthermore, the positioning rod of the positioning pin and the through hole on the support beam and the stepped hole of the anti-detachment ring are all clearance fit. The diameter of the positioning head of the positioning pin is smaller than the diameter A of the stepped hole of the anti-detachment ring, but larger than the diameter B, thus playing a limiting role.

[0013] When in use, place the anti-detachment ring on the spraying fixture, align the through hole on the support beam with the stepped hole on the anti-detachment ring, and finally pass the positioning pin through the stepped hole of the anti-detachment ring and the through hole of the support beam in sequence to limit the anti-detachment ring on the fixture. Finally, place the fixture on the painting line for spraying operation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention enables the anti-detachment ring to be automatically sprayed on a spraying line. It has a simple structure, is easy to install and manufacture. Different spraying fixtures can be designed and manufactured according to the different sizes of the anti-detachment rings. It is reusable, saves resources, improves spraying efficiency, eliminates manual spraying, reduces the input of consumables, greatly reduces the production and manufacturing cost of anti-detachment ring spraying, and improves production efficiency and quality.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a spraying fixture for an aluminum alloy wheel hub anti-detachment ring includes a bushing 1, a support beam 2, a positioning pin 3, and a nut 4. The bushing 1 is cylindrical and has a groove 1-1, an outer recess 1-2, and an inner recess 1-3. The support beam 2 has a through hole 2-1, a support beam cap 2-2, a mating surface 2-3, a rod body 2-4, and a thread 2-5. The positioning pin 3 has a positioning head 3-1 and a positioning rod 3-2. The anti-detachment ring 5 has a stepped hole 5-1.

[0027] During assembly, first place the support beam 2 into the slot 1-1 of the bushing 1, and place the support beam cap 2-2 on the support beam 2 into the inner recess 1-3 of the bushing 1. The mating surface 2-3 of the support beam 2 should fit against the bottom surface of the inner recess 1-3 of the bushing 1. Then, connect the support beam 2 and the bushing 1 together with the nut 4 to ensure that the axis of the central hole of the bushing 1 is consistent with the direction of the central axis of the support beam through hole 2-1.

[0028] Furthermore, the outer recess 1-2 and the inner recess 1-3 of the bushing 1 are coaxial, and the axes of the multiple recesses are on the same plane.

[0029] Furthermore, the diameter of the thread 2-5 of the support beam 2 and the diameter of the rod body 2-4 are clearance fits with the groove 1-1 of the bushing 1, with a clearance of 0.5-2mm.

[0030] Furthermore, the diameter of the support beam cap 2-2 is larger than the width of the groove 1-1 on the bushing 1 to prevent the support beam 2 from falling off.

[0031] Furthermore, the length of the rod body 2-4 on the support beam 2 is less than the wall thickness D of the bushing 1, while the total length L of the thread 2-5 on the support beam 2 and the rod body 2-4 is greater than the wall thickness D of the bushing 1, ensuring that the nut 4 can be locked.

[0032] Furthermore, the positioning rod 3-2 of the positioning pin 3 is clearance-fitted with the through hole 2-1 on the support beam 2 and the stepped hole 5-1 of the anti-detachment ring 5. The diameter of the positioning head 3-1 of the positioning pin 3 is smaller than the large diameter A of the stepped hole 5-1 of the anti-detachment ring, but larger than the small diameter B of the stepped hole 5-1 of the anti-detachment ring, thus playing a limiting role.

[0033] When in use, place the anti-detachment ring 5 on the spraying fixture. The through hole 2-1 on the support beam 2 corresponds to the stepped hole 5-1 on the anti-detachment ring. Finally, the positioning pin 3 passes through the stepped hole 5-1 of the anti-detachment ring and the through hole 2-1 of the support beam in sequence to limit the anti-detachment ring 5 on the fixture. Finally, place the fixture on the painting line for spraying operation.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
