Through the electrophoretic process, a uniform and dense coating film can be formed on the surface of the torsion bar, which plays a role in corrosion prevention and aesthetics.

[0003] In existing technologies, since most suspension torsion bars are made of steel and aluminum, different materials often require different electrophoretic coating tanks during the electrophoretic process.

[0026] The high-pressure nozzle 11 can be used to rinse the bottom of the module box 3 and the second main connecting pipe 23 and the second auxiliary connecting pipe 24 at the bottom when the module box 3 is replaced according to different materials of the suspension torsion bar. This is to avoid the mutual contamination of the electrophoretic solution residues of different materials, which would affect the electrophoretic processing effect of the suspension torsion bars of different materials. The modular design of the module box 3 and the two buffer tanks 5 containing steel and aluminum electrophoretic solutions respectively can be adapted to the quick replacement of the module box 3 for suspension torsion bars of different materials, so as to improve the electrophoretic processing effect of the suspension torsion bars.

[0027] Please see Figures 3-4 In this embodiment, a bearing base 1 is installed at the lower end of the base box 2. The lower ends of the CNC module 6 and the buffer tank 5 are connected to the inner wall of the lower end of the bearing base 1. The CNC module 6 is located between the two sets of buffer tanks 5. The bearing base 1 can provide stable support and bearing for the base box 2 to prevent it from tipping over during use. Support frames 8 are fixed to the inner walls of the left and right ends of the base box 2. Three sets of equidistant auxiliary rollers 9 are rotatably installed in the support frame 8. Two sets of pneumatic locking pins 22 are symmetrically distributed at the front and back at the edge of the support frame 8. The support frame 8 can rotate to support and install the auxiliary rollers 9.

[0028] Please see Figures 4-6 In this embodiment, the module box 3 is set inside the base box 2. Three sets of equally spaced sliding grooves 18 are opened at the left and right ends of the module box 3. Pin grooves 19 are symmetrically distributed at the left and right edges of the module box 3. The pin grooves 19 and the pneumatic locking pins 22 can assist in the left and right direction of the module box 3 after it is installed in the base box 3 by hoisting it along the outer wall of the auxiliary rollers 9. The sliding grooves 18 are adapted to the auxiliary rollers 9, and the pneumatic locking pins 22 are adapted to the pin grooves 19. The auxiliary rollers 9 can assist in the module box 3 to be hoisted out of the base box 2 for replacement. The front end of the base box 2 is provided with a first groove 7. The inner wall of the first groove 7 is hinged with two sets of door panels 4 symmetrically distributed on the left and right. The upper four corner edges of the module box 3 are fixed with hangers 20. The hangers 20 can facilitate the user to use a forklift to lift the module box 3.

[0029] Please see Figures 4-7In this embodiment, a limiting plate 10 is installed at the upper end of the base box 2. The inner wall of the limiting plate 10 fits against the outer wall of the module box 3. The limiting plate 10 can assist in the lifting and replacement of the module box 3, thereby further improving the stability and convenience of the module box 3 during lifting and replacement. The sewage pipe 13 and the first main connecting pipe 16 are located between two sets of ramps 12. The first auxiliary connecting pipe 15 and the second main connecting pipe 23 are connected by quick-release flanges. The first main connecting pipe 16 and the second auxiliary connecting pipe 24 are connected by quick-release flanges. The connection of the first auxiliary connecting pipe 15, the second main connecting pipe 23, the first main connecting pipe 16 and the second auxiliary connecting pipe 24 by quick-release flanges makes it convenient for users to connect and install the replacement module box 3 and the base box 2.

[0030] In this utility model, the CNC module 6 is connected to the liquid supply system, circulation system, and temperature control system via an auxiliary connecting pipe 17. The two sets of buffer tanks 5 respectively store steel electrophoresis solution and aluminum electrophoresis solution. The specific implementation scheme is as follows:

[0031] When processing steel suspension torsion bars, the special module box 3 is first hoisted above the base box 2. At the same time, it slides into the base box 2 through the sliding groove 18 and the auxiliary roller 9 in the base box 2 and is positioned by the limiting plate 10. After the sliding installation is in place, the pneumatic locking pin 22 extends into the pin groove 19 to complete the mechanical fixation. Then, the door panel 4 is opened, and the first auxiliary connecting pipe 15 and the second main connecting pipe 23, the first main connecting pipe 16 and the second auxiliary connecting pipe 24 are connected by manual operation of the quick-release flange so that the buffer tank containing steel electrophoretic liquid is connected to the module box 3. The CNC module 6 controls the buffer tank 5 containing steel electrophoretic liquid to inject the special electrophoretic liquid into the module box 3 through the pipeline. Then, the suspension torsion bar that needs to be electrophoretically processed is placed into the module groove through the suspension frame. At the same time, the electrode 21 is energized to form a uniform coating on the surface of the steel or aluminum torsion bar in the electrophoretic liquid.

[0032] When processing aluminum suspension torsion bars, first pump the steel special electrophoretic solution in the control module box 3 into the buffer tank 5 in reverse through the second main connecting pipe 23 and the first auxiliary connecting pipe 15. Then disconnect the quick-release flange, loosen the pneumatic locking pin 22, and move the steel module box 3 out along the auxiliary roller 9 through the hanger 20 and store it. At the same time, re-lift the aluminum adapter module box 3 and repeat the above operation of the installation process.

[0033] When hoisting the steel adapter module box 3, a cleaning fluid is sprayed into the module box 2 through the high-pressure nozzle 11 to clean the steel adapter electrophoresis fluid remaining on the pipeline of the steel adapter module box 3, so as to avoid cross-contamination between the steel adapter electrophoresis fluid and the subsequent aluminum adapter electrophoresis fluid. The waste liquid will flow into the drain pipe 13 along the two sets of ramps 12 and be discharged and collected.

[0034] Through the above steps, the high-pressure nozzle 11 can flush the bottom of the module box 3 and the second main connecting pipe 23 and the second auxiliary connecting pipe 24 at the bottom when the module box 3 is replaced according to the different materials of the suspension torsion rods. This is to avoid the mutual contamination of the electrophoretic solution residues of different materials, which would affect the electrophoretic processing effect of the suspension torsion rods of different materials. The modular design of the module box 3 and the two buffer tanks 5 containing steel and aluminum electrophoretic solutions respectively can be adapted to the quick replacement of the module box 3 for suspension torsion rods of different materials, thereby improving the electrophoretic processing effect of the suspension torsion rods. This solves the problem that the electrophoretic pool in the existing electrophoresis device is difficult to be quickly replaced according to the processing needs of different materials, and that the electrophoretic solution is easy to contaminate each other during replacement.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
