[0018] 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 scope of protection of the present utility model.

[0019] Please see Figure 1-6 This utility model provides a technical solution: a vehicle body tilting mechanism, including a walking frame assembly 1, a rotating shaft 2, a bracket 3, a conductive copper brush assembly 4, and a locking assembly 6; The walking frame assembly 1 serves as the main load-bearing structure of the equipment, including a walking frame 101, a sleeve 102, and a mounting base 106. The walking frame 101 is welded from square tubes or steel sections, and has high rigidity and torsional resistance. The lower end of the walking frame 101 is provided with a groove that mates with the friction wheel of the roller bed. A motor-driven friction wheel is provided on one side of the production line, which directly drives the walking frame 101 to move through friction, thereby pushing the entire tilting mechanism forward or backward. The sleeve 102 is fixed to the inner side of the walking frame 101. The rotating shaft 2 passes through the sleeve 102 and is rotatably connected to the sleeve 102 by a bearing. The outer side of the walking frame 101 is provided with a mounting seat 106 for installing the locking assembly 6. The bracket 3 is installed on the outer side of the pivot 2, and the upper end of the bracket 3 is used to support the skid that carries the vehicle body. One end of the rotating shaft 2 is connected to the rotating wheel 5. One end of the rotating wheel 5 is symmetrically fixed with guide plates 10. The two guide plates 10 are adapted to the size of the Y-shaped tilting frame of the external tilting motor. When it reaches the tilting station, the tilting wheel on the external tilting motor is inserted between the two guide plates 10. The external tilting motor controls the rotation of the tilting wheel, which in turn drives the rotating wheel 5 and the rotating shaft 2 to rotate, thereby realizing the tilting of the vehicle body. The external tilting motor will move together with this tilting mechanism until it leaves the tilting area, at which point the tilting wheel separates from the guide plate 10. The conductive copper brush assembly 4 is symmetrically installed on both sides of the end face of the rotating wheel 5 to ensure that the electrophoresis current is smoothly delivered to the car body; The locking assembly 6 includes two parallel locking plates 601. A retaining wheel 603 is provided on one side of the upper end between the two locking plates 601. A fixed plate 7 is fixed on the outer side of the rotating shaft 2. The fixed plate 7 is located on one side of the rotating wheel 5. A notch is provided on the fixed plate 7, and the retaining wheel 603 is fitted into the notch. One side of the locking plate 601 is an arc-shaped structure that matches the outer circle of the fixed plate 7. A pin 602 is passed through the other side of the upper end between the two locking plates 601. The pin 602 is rotatably connected in the mounting base 106. After entering the flipping station, the locking plate 601 is controlled to rotate around the pin 602 by the opening mechanism on one side of the production line, so that the retaining wheel 603 is separated from the fixed plate 7, thereby allowing the external flipping motor to control the rotation of the rotating shaft 2. When it is about to leave the flipping area, the retaining wheel 603 is reset by the locking mechanism to prevent the rotating shaft 2 from being accidentally unlocked when not flipping, thus improving production safety.

[0020] To prevent the traveling frame 101 from directly colliding with other traveling frames 101 or equipment during its movement, buffer bars 104 are installed at both ends of the traveling frame 101.

[0021] To ensure the stability of the movement of the walking frame assembly 1, a guide wheel 103 is provided below the buffer rod 104. The guide wheel 103 is installed at both ends of the walking frame 101 and moves along a preset track.

[0022] To prevent liquid in the electric pool from splashing onto the conductive copper brush assembly 4 and affecting its conductivity, a water baffle 105 is provided on one side of the walking frame 101, and the water baffle 105 is located above the sleeve 102.

[0023] To further ensure the walking stability of the walking frame assembly 1, a driven wheel 8 is provided at the other end of the rotating shaft 2, and the driven wheel 8 moves along the guide rail on the production line.

[0024] To accurately sense the position of the flipping mechanism, a T-shaped sensing plate 604 is installed on the upper side of one side of the locking plate 601. The upper end of the T-shaped sensing plate 604 is higher than the top of the locking plate 601. A corresponding proximity switch, photoelectric sensor or RFID reader is set on one side of the production line. When the T-shaped sensing plate 604 is sensed, the signal is sent to the central PLC controller to start a series of flipping actions.

[0025] In order to adjust the position and height of the T-shaped sensing plate 604 according to the position of the inductive switches on different production lines, thereby ensuring sensing accuracy, the lower end of the T-shaped sensing plate 604 is symmetrically provided with vertical strip holes 605. A fixing plate 606 is fixed on one side of the locking plate 601. The fixing plate 606 has horizontal strip holes 607 perpendicular to the direction of the vertical strip holes 605. The same bolt passes through the horizontal strip holes 607 and the vertical strip holes 605 for fixing. By adjusting the position of the bolt in the horizontal strip holes 607 and the vertical strip holes 605, the position and height of the T-shaped sensing plate 604 can be changed.

[0026] To avoid the impact of humid environment on the conductive copper brush assembly 4 and extend its service life, an insulating plate 11 is installed on the guide plate 10, and an insulating box 9 is fixed on the insulating plate 11. The conductive copper brush assembly 4 is installed in the insulating box 9.

[0027] In order to position the rotating wheel 5 when the flipping mechanism is not working, multiple toothed structures are evenly distributed on the outer surface of the rotating wheel 5, which are used to cooperate with the external ratchet locking wheel to limit its movement.

[0028] In use: The initial state of the flipping mechanism is the locked state. The flipping machine carrying the white body is driven by the external friction wheel and runs along the track to the flipping station at the entrance of the electrophoresis tank. The sensor next to the track detects the equipment in place through the sensing T-shaped sensing plate 604 and sends a signal to the PLC. The PLC first controls the opening device located on one side of the production line to rotate the locking plate 601, pulling the chuck 603 out of the notch on the outer fixing plate 7 of the rotating shaft 2. It confirms the "unlocking successful" signal and sends feedback. As the flipping mechanism moves, the Y-shaped flipping frame on the external flipping motor enters horizontally between the two guide plates 10 at one end of the rotating wheel 5. Then, the PLC starts the external flipping motor, which controls the Y-shaped flipping frame to rotate, thereby driving the rotating wheel 5 to rotate, which in turn drives the rotating shaft 2 to rotate slowly and precisely (e.g., 0° -> 90° -> 180°), so that the car body is immersed in the electrophoresis tank at the optimal angle. During this process, the external flipping motor moves synchronously with the flipping mechanism. After electrophoresis, the external flipping motor rotates in the opposite direction to lift the car body out and rotate it to 45° for draining. After draining, it flips to a horizontal position. Once in place, the PLC controls the closing device on one side of the production line to operate, controlling the locking plate 601 to rotate in the opposite direction, locking the jack 603 into the notch on the fixed plate 7, confirming "locking successful". Finally, the external friction wheel restarts, transporting the locked flipping mechanism to the next process. Throughout the process, all key actions are detected and fed back by sensors, forming a safety interlock.
