A support column is fixedly connected to the middle of the bottom end of the shell, and a support plate is fixedly connected to the top of the support column. Baffles are fixedly connected to both ends of the shell, and through holes are opened inside the baffles. A clamping assembly is provided inside the shell, which includes a hydraulic workpiece, a rotating shaft, a clamping component, and a metal gasket. Solid waste collection boxes are fixedly connected to both sides inside the shell, and a sliding block is provided on one side of the solid waste collection box. In the technical solution provided by this utility model, by adjusting the position of the hydraulic workpiece, the fixture can clamp workpieces of various types, thereby facilitating electrophoretic coating treatment on various clamped workpieces and greatly reducing production costs.

[0003] In the prior art, including the aforementioned patents, automotive parts are mostly positioned using suspension points during electrophoretic coating production. However, due to factors such as liquid flow during electrophoresis, the parts are prone to shaking, affecting positioning accuracy. This method is not very adaptable to parts with irregular shapes or large size differences. Replacing different parts may require replacing or adjusting a large number of suspension components, which is cumbersome. Therefore, it is necessary to design a fixture for electrophoretic coating production of automotive parts that reduces the influence of fluid. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for electrophoretic coating production of automotive parts, so as to solve the problems of fluid influence and part size differences mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for electrophoretic coating production of automotive parts, comprising a frame, an operating frame fixedly connected inside the frame, a cylinder mounted on the outer wall of the operating frame, a drag chain fixedly connected to the output end of the cylinder, an air jet gun assembly mounted on one end of the drag chain, a support frame mounted at the bottom of the operating frame, a clamping assembly mounted on the outer wall of the support frame, a base fixedly connected inside the frame, and an electrophoretic coating pool provided on the top of the base.

[0006] Furthermore, two sets of cable chains are installed on the outer walls of both sides of the operating frame, and the other end of the cable chains is connected to the operating frame.

[0007] Furthermore, the jet gun assembly is mounted obliquely above the clamping assembly, and the jet gun assemblies are symmetrical to each other along the operating frame.

[0008] Furthermore, the clamping assembly is located above the electrophoretic pool, and the rotating support surface of the clamping assembly is lower than the horizontal plane of the electrophoretic pool, and the interior of the electrophoretic pool is filled with acidic electrophoretic coating.

[0009] Furthermore, the clamping assembly includes a clamping seat, a support shaft, an electric telescopic rod, a connecting shaft, and a limiting gripper. The clamping seat is installed at the bottom of the operating frame. The support shaft is slidably installed inside the clamping seat. The electric telescopic rod is provided on the outer wall of the support shaft. The output end of the electric telescopic rod is fixedly connected to the connecting shaft. The limiting gripper is connected to the bottom rotating shaft of the clamping seat.

[0010] Furthermore, the outer wall of the support frame is provided with a sliding groove, and the support shaft passes through the sliding groove.

[0011] Furthermore, one end of the electric telescopic rod is connected to the limiting gripper via a connecting shaft, and the limiting gripper has a rotatable angle of 60°.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the fixture for electrophoretic coating production of automotive parts is reasonable and has the following advantages:

[0013] (1) The automotive parts are clamped and fixed by clamping components. The gripper type fixture is used instead of the suspension type fixture. The limit gripper can clamp and position the parts from multiple directions. The gripper position and force can be precisely adjusted according to the shape and size of the parts to ensure the stability of the parts during the electrophoresis process and ensure the uniformity and quality of the coating. For example, for complex automotive interior parts, the gripper type fixture can better fit the contour and position them. At the same time, a more compact layout can be adopted, and more fixtures can be arranged in a limited space to increase the part processing volume per unit area and improve the space utilization of the production line. It is especially suitable for the scenario of dense coating of small parts. The gripper structure can be flexibly adjusted and combined to quickly adapt to automotive parts of different shapes and sizes. By changing the gripper head or adjusting the limit gripper angle, the electrophoretic coating needs of various parts can be met, improving the versatility and flexibility of the production line. The gripper type fixture can be well adapted to different parts such as automotive engine hoods and doors.

[0014] (2) By using the clamping assembly for clamping operation, the movement is relatively simple and the wear of the gripping parts is small. The extension and retraction of the electric telescopic rod can drive the limit gripping to rotate, making the clamping method simpler. The gripping structure is easier to clean and protect, reducing electrophoretic fluid corrosion, extending the service life of the clamp, and reducing maintenance costs. At the same time, an air gun assembly is also set on the top, which can pneumatically clean automotive parts and also clean the limit gripping, reducing the accumulation of electrophoretic fluid.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A fixture for electrophoretic coating production of automotive parts includes a frame 1, an operating frame 2 fixedly connected inside the frame 1, a cylinder 3 mounted on the outer wall of the operating frame 2, a drag chain 4 fixedly connected to the output end of the cylinder 3, an air jet gun assembly 5 mounted on one end of the drag chain 4, a support frame 6 mounted at the bottom of the operating frame 2, a clamping assembly 7 mounted on the outer wall of the support frame 6, a base 8 fixedly connected inside the frame 1, and an electrophoretic coating pool 9 disposed on the top of the base 8.

[0025] The above structure clamps and fixes automotive parts through clamping component 7, and uses a gripper-type clamp instead of a suspension clamp. The limiting gripper 705 can clamp and position the parts from multiple directions. The gripper position and force can be precisely adjusted according to the shape and size of the parts to ensure the stability of the parts during the electrophoresis process and to ensure the uniformity and quality of the coating.

[0026] Furthermore, two sets of drag chains 4 are installed on the outer walls of both sides of the operating frame 2, and the other end of the drag chain 4 is connected to the operating frame 2. The jet gun assembly 5 is installed obliquely above the clamping assembly 7, and the jet gun assembly 5 is symmetrical to each other along the operating frame 2. The clamping assembly 7 is located above the electric pool 9. After the clamping assembly 7 is rotated, the support surface is lower than the horizontal plane of the electric pool 9, and the inside of the electric pool 9 is filled with acidic electrophoretic coating.

[0027] The above structure can adopt a more compact layout, which can arrange more fixtures in a limited space, increase the amount of parts processed per unit area, and improve the space utilization of the production line. It is especially suitable for scenarios where small parts are densely painted. The gripping structure can be flexibly adjusted and combined, and can quickly adapt to automotive parts of different shapes and sizes.

[0028] Furthermore, the clamping assembly 7 includes a clamping seat 701, a support shaft 702, an electric telescopic rod 703, a connecting shaft 704, and a limiting gripper 705. The clamping seat 701 is installed at the bottom of the operating frame 2. The support shaft 702 is slidably installed inside the clamping seat 701. The electric telescopic rod 703 is provided on the outer wall of the support shaft 702. The output end of the electric telescopic rod 703 is fixedly connected to the connecting shaft 704. The bottom rotating shaft of the clamping seat 701 is connected to the limiting gripper 705. The outer wall of the support frame 6 is provided with a sliding groove, and the support shaft 702 passes through the sliding groove. One end of the electric telescopic rod 703 is connected to the limiting gripper 705 through the connecting shaft 704, and the rotatable angle of the limiting gripper 705 is 60 degrees.

[0029] The above structure can meet the electrophoretic coating needs of various parts by changing the gripper head or adjusting the 705 angle of the limiting gripper, thereby improving the versatility and flexibility of the production line. Different parts such as car engine hoods and car doors can be well adapted to the gripper fixture.

[0030] Working principle: In use, firstly, the clamping operation is performed by using the clamping component 7, which is relatively simple and has less wear on the gripping parts. The extension and retraction of the electric telescopic rod 703 can drive the limit gripper 705 to rotate, making the clamping method simpler. The extension and retraction of the electric telescopic rod 703 drives the support shaft 702 and the connecting shaft 704 to move, so that the limit gripper 705 rotates along the rotating shaft, thereby grabbing the car parts that are stuck on the previous conveyor belt. The two sides are set to prevent shaking during the gripping process.

[0031] Secondly, the clamping assembly 7 clamps and fixes the automotive parts, using a gripper-type clamp instead of a suspension clamp. The limiting gripper 705 can clamp and position the parts from multiple directions. The gripper position and force can be precisely adjusted according to the shape and size of the parts to ensure the stability of the parts during the electrophoresis process, ensuring the uniformity and quality of the coating. For example, for complex automotive interior parts, the gripper-type clamp can better fit their contours and position them. At the same time, a more compact layout can be adopted, allowing more clamps to be arranged in a limited space, increasing the amount of parts that can be processed per unit area.

[0032] Finally, cylinder 3 drives the drag chain 4 to move, thereby driving the jet gun assembly 5 to adjust and clean the surface of the limit gripper 705. It is connected to an external pneumatic system to perform airflow cleaning, making the gripper structure easier to clean and protect, reducing electrophoretic fluid corrosion, extending the service life of the clamp, and reducing maintenance costs. At the same time, the jet gun assembly 5 is also set above, which can perform pneumatic cleaning of automotive parts and also clean the limit gripper 705, reducing the accumulation of electrophoretic fluid.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
