Description

Technical Field

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

[0002] With the booming car modification market, people are paying more and more attention to aluminum alloy wheels with anti-loosening ring structures, resulting in a growing demand for anti-loosening ring wheels. In the manufacturing process of anti-loosening rings, just like in wheel manufacturing, an anti-loosening ring is attached to a tool and painted together with the wheel. However, since anti-loosening ring products are similar to ring-shaped products, the space in the middle is not utilized and is wasted. Therefore, for manufacturers, improving production efficiency is an urgent issue that needs to be addressed.

[0003] Therefore, an improved aluminum alloy wheel hub anti-detachment ring spraying fixture is needed to make full use of the space of the spraying fixture, with a simple structure, convenient operation, and reusability, thereby improving the production efficiency of the anti-detachment ring.

[0004] The purpose of this invention is to provide an improved aluminum alloy wheel hub anti-detachment ring spraying fixture, which makes full use of the space of the anti-detachment ring spraying fixture, improves the efficiency of existing aluminum alloy wheel hub anti-detachment ring spraying, and thus greatly reduces the production cost of anti-detachment rings.

[0005] The technical solution of this utility model:

[0006] An improved aluminum alloy wheel hub anti-detachment ring spraying fixture includes a central ring, a support beam, and a pin. The central ring has a positioning groove and a central hole, the support beam has a through hole and an end face, and the pin has a pin cap and a pin rod. The positioning groove of the support beam and the central ring are clearance fit, the end face of the support beam contacts the bottom of the positioning groove of the central ring, the through hole on the support beam corresponds to the stepped hole on the anti-detachment ring, the through hole on the support beam and the pin rod are clearance fit, and the anti-detachment ring has a stepped hole.

[0007] Furthermore, the support beam and the central ring are welded together to ensure that the axis of the central hole of the central ring is aligned with the central axis of the through hole of the support beam.

[0008] Furthermore, the wall thickness of the central ring should be 5-10mm. If it is too thin, it is easy to deform and will not provide support during use.

[0009] Furthermore, the central ring is provided with four positioning slots, which are evenly distributed around the central ring.

[0010] Furthermore, the central ring is cylindrical, the bottom surface of the positioning groove of the central ring is flat, and the diameter of the central hole must meet the on-site production requirements and match the spraying line.

[0011] Furthermore, the support beam has multiple through holes, each corresponding to a stepped hole in an anti-detachment ring of a different size.

[0012] Furthermore, the through holes on the support beam and the pin rod are clearance fit, with a clearance of 0.5-2mm, which facilitates disassembly.

[0013] Furthermore, the positioning grooves of the support beam and the central ring are clearance fits, with a clearance of 0.2-1mm.

[0014] Furthermore, the end face of the support beam contacts the bottom of the positioning groove of the central ring and is then welded firmly to ensure that the welding is completed.

[0015] Furthermore, the pin and the stepped hole of the anti-detachment ring are fitted with a clearance of 0.5-2mm.

[0016] Furthermore, the through holes on the support beam correspond to the stepped holes on the anti-detachment ring, allowing the pin to pass through the anti-detachment ring and the support beam, with the axis of the anti-detachment ring coinciding with the axis of the central ring.

[0017] When using, the gap between adjacent anti-detachment rings should be greater than 10mm to ensure the coating effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this utility model realizes the placement of multiple anti-detachment rings on a tooling for spraying, which doubles the spraying efficiency, is simple to install and manufacture, can be reused, saves resources, reduces the input of consumables, greatly reduces the production and manufacturing cost of anti-detachment ring spraying, and improves production efficiency and quality.
