Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating of automotive parts, specifically a fixture for electrophoretic coating of automotive parts. Background Technology

[0002] Electrophoretic coating is a coating method that uses an electric field to cause charged paint particles to move directionally in the electric field and deposit on the surface of a workpiece. This method has a high degree of automation, stable coating quality, and significant paint savings, and is therefore widely used in many fields such as automobiles, home appliances, and building materials. To facilitate the clamping of automotive parts, fixtures are needed. The "Holder for Electrophoretic Coating of Automotive Parts" disclosed in application number "CN202321973503.8" is also an increasingly mature technology. It "provides installation conditions for the hook and the locking mechanism through the mounting mechanism; the hook is used to hang the item; the elastic mechanism is used to close the opening of the hook; and the return spring pushes the slider to press the item on the hook against the locking mechanism, reducing the shaking of the item." The present invention addresses the problem of items easily swinging when hung on existing clamps for electrophoretic coating of automotive parts. However, the clamp still has the following drawbacks: While the clamp, with its hook and return spring, does facilitate the clamping of automotive parts, the clamping force provided by the return spring alone is insufficient to stably hold larger automotive parts, posing a risk of parts falling off. Therefore, it is necessary to provide a clamp that facilitates stable clamping of automotive parts and enhances practicality. In addition, the current clamp is not easy to adjust its height according to the size and diameter of the automotive parts, which may result in parts not being fully submerged in the electrophoretic coating pool. Therefore, it is necessary to provide a clamp that is height-adjustable, suitable for electrophoretic coating of parts of different sizes, and enhances versatility. Utility Model Content

[0003] This utility model provides a fixture for electrophoretic coating of automotive parts, aiming to solve the problem that existing fixtures are not convenient for stably clamping and height-adjusting automotive parts of different sizes.

A first motor 102 is mounted on the back of the mounting plate 101. A rotating plate 103 is mounted on the output end of the first motor 102. Several transmission arms 104 are hinged to the surface of the rotating plate 103. Several guide grooves 105 are opened on the surface of the mounting plate 101. Guide blocks 106 are slidably connected inside the several guide grooves 105. An arc plate 107 is fixedly connected to the upper end of the guide block 106. Several conical nails 108 are fixedly connected to the inner wall of the arc plate 107. The lifting assembly 200 includes a connecting shaft 201 installed between two clamping assemblies 100. A support plate 202 is fixedly connected to the upper end of the connecting shaft 201. A positioning groove 203 is provided on the upper end of the support plate 202.

A toothed plate 206 is meshed inside the positioning groove 203 between the first gear 204 and the second gear 205. A transmission mechanism 207 is installed at one end of the second gear 205.

[0015] In one specific embodiment, the clamping assembly 100, in conjunction with the lifting assembly 200, not only facilitates multi-angle stable clamping of automotive parts, thus enhancing the practicality of the fixture, but also allows for height adjustment of automotive parts of different sizes through the interplay of these structures, facilitating omnidirectional electrophoretic coating operations and enhancing the fixture's versatility. In use, two automotive parts are first placed between several arc-shaped plates 107 on the surface of the mounting plates 101 at both ends of the connecting shaft 201. Then, the first motor 102 is started, causing the rotating plate 103 to rotate clockwise or counterclockwise, which in turn causes several transmission arms 104 to extend and retract, thereby enabling the guide block 106 and the arc-shaped plates 107 on its surface to be clamped. By pulling or supporting, several arc-shaped plates 107 can clamp automotive parts. The conical nails 108 on the inner wall of the arc-shaped plates 107 not only increase the clamping stability of the arc-shaped plates 107 for automotive parts, but also reduce the contact area to ensure all-round electrophoretic coating operation. At the same time, the transmission mechanism 207 is activated to rotate the second gear 205 clockwise or counterclockwise. The toothed plate 206 meshes with the first gear 204 and the second gear 205, thereby controlling the support plate 202 to rise and fall along the positioning groove 203 between the first gear 204 and the second gear 205. This allows for adjustment of the height of the connecting shaft 201 and the clamping components 100 at both ends, thereby enhancing the versatility of the fixture.
