Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic coating, in particular to an electrophoretic shielding device for automobile parts which is convenient for quick disassembly and assembly. Background Art

[0002] With the rapid development of the automobile industry, higher requirements are placed on the surface coating quality of automobile parts. As an efficient and environmentally friendly coating method, electrophoretic coating technology has been widely used in the field of automobile manufacturing. However, in the electrophoretic coating process, how to ensure that the non-coating area is effectively shielded to prevent the penetration of electrophoretic liquid has become an urgent problem to be solved. Traditional electrophoretic shielding devices for automobile parts usually adopt a fixed structure, and the installation and disassembly process is cumbersome and the work efficiency is low. In addition, due to the different shapes and sizes of different automobile parts, traditional shielding devices often cannot adapt to the diverse coating requirements, resulting in unstable coating quality and increased manufacturing costs.

[0003] When in use, some existing electrophoretic shielding devices prevent the electrophoretic fluid from entering the conductive area of ​​the workpiece by putting an isolation sleeve on the workpiece. However, the operator is required to put the isolation sleeve on the conductive area of ​​the workpiece very carefully and accurately. Since the shapes and sizes of the workpieces may be different, the positions and sizes of the conductive areas may also be different, which increases the complexity and difficulty of the operation and makes it impossible to quickly disassemble and assemble the isolation sleeve.

[0004] For example, a local electrophoresis shielding device is disclosed in the publication number CN215628362U. This patent realizes local shielding of the workpiece to be electrophoresed by means of a liquid-proof sleeve component on a clamp mechanism. The liquid-proof sleeve component is sealingly sleeved on the conductive area of ​​the workpiece to be electrophoresed, effectively preventing the electrophoresis liquid from entering the area.

[0005] Although the operation of sealing the liquid-proof cover component on the conductive area of ​​the workpiece to be electrophoresed can prevent the ingress of electrophoretic liquid, the liquid-proof cover component needs to be tightly fitted on the conductive area of ​​the workpiece to be electrophoresed to ensure that the electrophoretic liquid does not penetrate into the conductive area, which requires the operator to be very careful and precise when covering the conductive area. However, since the shapes and sizes of the workpiece to be electrophoresed may vary, the position and size of the conductive area may also vary, which increases the complexity and difficulty of the operation.

[0006] Therefore, it is necessary to invent an electrophoresis shielding device for automobile parts that is easy to quickly disassemble and assemble to solve the above problems. Utility Model Content

[0007] The utility model aims to provide an electrophoresis shielding device for automobile parts which is convenient for quick disassembly and assembly, so as to solve the problems in the above-mentioned technology.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electrophoretic shielding device for automobile parts that is easy to quickly disassemble and assemble, comprising a loading rack, rubber airbags are installed on both sides of the inner wall of the loading rack, a transfer rod is fixedly connected to the top of the loading rack, an air hose is arranged on the surface of the transfer rod, a pipe interface is fixedly connected to the top of the air hose, the bottom end of the air hose passes through the loading rack and is connected to the interior of the rubber airbag, an auxiliary mechanism is arranged between the two sides of the inner wall of the loading rack, and the auxiliary mechanism is arranged below the rubber airbag.

[0009] After being inflated, the rubber airbag can fit closely to the surface of automobile parts, forming an effective electrophoresis shield to prevent the infiltration of electrophoresis liquid and ensure the quality of electrophoresis.

[0010] Preferably, a mounting plate is fixedly connected to the top end of the transfer rod, and a limiting buckle is fixedly connected to the surface of the transfer rod.

[0011] The mounting plate facilitates the installation and fixation of the overall device, while the limiting buckle ensures that the position of the gas hose on the transfer rod is stable to prevent the hose from moving or falling off.

[0012] Preferably, the air circuit hose is snap-connected with a limit buckle, the limit buckles are provided in a plurality, and the plurality of limit buckles are distributed in a linear array from top to bottom.

[0013] The provision of multiple limit buckles increases the flexibility of fixation and is suitable for air hoses of different lengths.

[0014] Preferably, the auxiliary mechanism includes a bidirectional lead screw, a limiting slide rod and a limiting clamp plate, the bidirectional lead screw is rotatably connected between the two sides of the inner wall of the loading frame, and the limiting slide rod is fixedly connected between the two sides of the inner wall of the loading frame.

[0015] The auxiliary mechanism can quickly clamp or release parts to improve work efficiency.

[0016] Preferably, the bidirectional lead screw and the limit slide rod are both arranged through the limit clamp plate, the bidirectional lead screw is transmission-connected to the limit clamp plate, and the limit slide rod is slidingly connected to the limit clamp plate.

[0017] The rotation of the bidirectional lead screw will cause the two limit clamps to move toward or away from each other along the limit slide bar. During this process, the limit slide bar ensures that the movement of the limit clamps is smooth and linear to prevent them from deflecting.

[0018] Preferably, the number of the limiting clamps is set to two, and the two limiting clamps are symmetrically distributed about the center line of the loading frame.

[0019] The two limit clamps clamp the parts from both sides at the same time, with uniform clamping force, which can ensure that the parts are initially fixed.

[0020] Preferably, a rubber pad is fixedly connected to the surface of the limiting clamping plate, and the surface of the rubber pad is provided with anti-slip corrugations.

[0021] The rubber pad can increase the friction with the surface of the part to prevent the part from sliding, and the anti-slip corrugation further increases the friction to ensure the stability of the part when it is initially fixed.

[0022] Preferably, one end of the bidirectional lead screw extends to the outside of the loading frame and is fixedly connected to a rotating disk.

[0023] The rotating disk makes the rotation operation of the bidirectional lead screw more convenient. The operator can easily drive the movement of the limit clamp by rotating the rotating disk, thereby improving work efficiency.

[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] 1. By arranging rubber airbags on both sides of the inner wall of the loading rack, the parts can be tightly wrapped and clamped by the expansion of the rubber airbags, forming a closed electrophoresis environment, which can effectively prevent the infiltration of electrophoresis liquid, and the inflation and deflation of the rubber airbags are simple and convenient, which is conducive to improving work efficiency;

[0026] 2. By setting an auxiliary mechanism under the rubber airbag, the parts are initially clamped by using a combination of a bidirectional lead screw and a limit clamp to prevent the parts from moving, so as to facilitate the subsequent fixation of the parts by the expansion of the rubber airbag.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The utility model provides Figure 1-5 An electrophoretic shielding device for automobile parts that is easy to quickly disassemble and assemble is shown, comprising a loading rack 1, with rubber airbags 2 installed on both sides of the inner wall of the loading rack 1, a transfer rod 3 fixedly connected to the top of the loading rack 1, an air hose 4 provided on the surface of the transfer rod 3, a pipe interface 5 fixedly connected to the top of the air hose 4, the bottom end of the air hose 4 passes through the loading rack 1 and is connected to the inside of the rubber airbag 2, an auxiliary mechanism 6 is provided between the two sides of the inner wall of the loading rack 1, and the auxiliary mechanism 6 is provided below the rubber airbag 2.

[0036] In one aspect of the present embodiment, the top of the transfer rod 3 is fixedly connected to a mounting plate 7, the surface of the transfer rod 3 is fixedly connected to a limit buckle 8, the air hose 4 is clamped with the limit buckle 8, the number of the limit buckles 8 is set to multiple, and the multiple limit buckles 8 are distributed in a linear array from top to bottom, the auxiliary mechanism 6 includes a bidirectional lead screw 9, a limit slide bar 10 and a limit clamp plate 11, the bidirectional lead screw 9 is rotatably connected between the two sides of the inner wall of the loading frame 1, and the limit slide bar 10 is fixedly connected to the two sides of the inner wall of the loading frame 1 The two-way lead screw 9 and the limit slide 10 are both arranged through the limit clamp 11, the two-way lead screw 9 is transmission-connected with the limit clamp 11, the limit slide 10 is slidingly connected with the limit clamp 11, the number of the limit clamps 11 is set to two, the two limit clamps 11 are symmetrically distributed about the center line of the loading frame 1, a rubber pad 12 is fixedly connected to the surface of the limit clamp 11, and the surface of the rubber pad 12 is provided with anti-slip corrugations, one end of the two-way lead screw 9 extends to the outside of the loading frame 1 and is fixedly connected to a rotating disk 13.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-5When using the utility model, first, place the automobile parts to be electrophoresed between the two limit clamps 11 in the loading rack 1 to ensure that the parts are located below the rubber airbag 2. Then, the operator manually rotates the rotating disk 13, and the rotating disk 13 drives the bidirectional screw 9 to rotate. Since the bidirectional screw 9 and the limit clamps 11 are transmission-connected, the rotation of the bidirectional screw 9 causes the two limit clamps 11 to move toward or away from each other along the limit slide bar 10. In this process, the limit slide bar 10 ensures that the movement of the limit clamps 11 is smooth and linear to prevent it from deflecting.

[0039] When the two limit clamps 11 move toward each other, they will clamp the automobile parts. Since the limit clamps 11 have rubber pads 12 on their surfaces, the anti-skid corrugations on the rubber pads 12 can increase the friction with the surface of the parts to prevent the parts from moving. At the same time, the rubber pads 12 can also play a buffering role to protect the parts from damage.

[0040] Then, the pipe interface 5 is connected to an external air pump, and gas is introduced into the air hose 4 through the air pump and the pipe interface 5. The gas flows into the rubber airbag 2 through the air hose 4, so that the rubber airbag 2 expands and fits tightly to the surface of the part, thereby wrapping and clamping the part. After that, the rotating disk 13 is rotated in the opposite direction to make the two limit clamps 11 move in opposite directions, thereby releasing the clamping of the automobile part.

[0041] At this time, the automobile parts are firmly fixed by the two rubber airbags 2, forming a closed electrophoresis environment. Next, the loading rack 1 can be placed in the electrophoresis tank as a whole for electrophoresis treatment.

[0042] After the electrophoresis is completed, the loading rack 1 is first taken out as a whole, and then the gas in the rubber airbag 2 is pumped out by an air pump to shrink the airbag. After that, the operator can easily take out the automobile parts that have been electrophoresed from the loading rack 1.

[0043] During the whole process, due to the quick disassembly and assembly design, such as the bidirectional lead screw 9 driving the two limit clamps 11 to move and the rapid inflation and deflation of the rubber airbag 2, the operation of the whole device is simple and quick, which greatly improves the work efficiency.
