Description

Technical Field

[0001] This utility model belongs to the field of spraying tooling technology, and relates to a suspended spraying tooling for coating ball pin products. Background Technology

[0002] Ball joints, also known as ball heads, ball joints, etc., are important components in automotive steering tie rod connections, primarily used for hinges in steering mechanisms, such as the connection between the steering mechanism and the suspension. Corrosion protection of ball joints is crucial for improving vehicle safety. Commonly used anti-corrosion processes include hot-dip galvanizing, electroplating, and zinc diffusion. With the increasing application of chromium-free zinc-aluminum coating technology in the market, its advantages are becoming more widely recognized by manufacturers. Depending on the application requirements, when using environmentally friendly Dacromet coating, only the portion below the ball head needs to be coated. The existing Dacromet coating process for ball joints involves tumbling, partial spraying, ball head painting, and packaging. First, the product is tumbling, then the ball head is covered using specialized tooling, and the portion below the ball head is manually sprayed. After coating, the ball head is painted, and finally, it is packaged and shipped. This process is relatively complex and inefficient, necessitating improvements to the production process to increase efficiency and reduce costs. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a suspended spraying fixture for coating ball pin products, which solves the problems of relatively complicated and inefficient Dacromet coating processes for ball pin products.

[0004] The objective of this utility model can be achieved through the following technical solutions: A suspended spraying fixture for coating ball pin-type products is characterized by comprising a support tube, on which several connecting square tubes are slidably and detachably connected, and metal support frames are fixedly connected around the connecting square tubes. An annular perforated plate is fixedly connected to the upper end of the metal support frame, and several placement holes are formed on the annular perforated plate.

[0005] In the aforementioned suspended spraying fixture for coating ball pin-type products, the support tube has several through holes, and the through holes are equipped with pins.

[0006] In the aforementioned suspended spraying fixture for coating ball pin products, the upper end of the support tube is provided with a hook.

[0007] In the aforementioned suspended spraying fixture for coating ball pin-type products, the metal support frame is triangular.

[0008] In the aforementioned suspended spraying fixture for coating ball pin products, the connecting square tube is detachably sleeved on the support tube.

[0009] Compared with the prior art, the present invention has the following advantages: This fixture is specifically designed for suspended spraying of ball pin products. The aperture and spacing of the fixture can be adjusted according to the different sizes of ball pins, thereby achieving multi-layer dense placement during the suspended spraying process. Compared with the original partial manual spraying method, the suspended spraying process using the fixture shortens the production process and the production time of the Dacromet coating step, thus effectively improving production efficiency and significantly reducing production costs. At the same time, the automatic spraying process can eliminate the impact on human health during manual spraying, and work safety is effectively guaranteed. Attached Figure Description

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] like Figures 1 to 3 As shown, A suspended spraying fixture for coating ball pin-type products is characterized by comprising a support tube 2, on which a plurality of connecting square tubes 3 are slidably and detachably connected, and metal support frames 4 are fixedly connected around the connecting square tubes 3. An annular perforated plate 5 is fixedly connected to the upper end of the metal support frame 4, and a plurality of placement holes 6 are provided on the annular perforated plate 5.

[0014] In this embodiment, based on the length of the ball pin to be processed, the sliding connection square tube 3 is used to adjust the spacing of different annular perforated plates 5 on the fixture. The ball pin to be sprayed is placed on the placement hole 6. The hole diameter and spacing can be adjusted according to the size of the ball pin to be processed, so that the ball pin is placed as densely as possible to fill the entire fixture for hanging spraying. Then, the entire fixture is suspended to the automatic spraying production line for automatic spraying. Finally, the customer performs coating removal treatment on the ball head and sprays oil. This fixture is specially used for hanging spraying of ball pin products. The hole diameter and spacing of the fixture can be changed according to the ball pin of different sizes, so as to achieve multi-layer dense placement in the hanging spraying process. Compared with the original process of partial manual spraying, the process mode of hanging spraying through the fixture shortens the production process and the production time of Dacromet coating steps, thereby effectively improving production efficiency and significantly reducing production costs. At the same time, the automatic spraying process can eliminate the impact on human health during manual spraying, and the work safety is effectively guaranteed.

[0015] In this embodiment, the support tube 2 has several through holes 7, and each through hole 7 has a pin 8. The pin 8 is inserted into the through hole 7 to limit the height position of the connecting square tube 3.

[0016] In this embodiment, the upper end of the support tube 2 is provided with a hook 9.

[0017] In this embodiment, the metal support frame 4 is triangular.

[0018] In this embodiment, the connecting square tube 3 is detachably sleeved on the support tube 2.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
