[0002] In the production process of automobile body painting, the electrophoresis process is an indispensable part. Electrophoresis is a kind of electroplating coating technology, which evenly deposits the electrophoresis coating on the surface of the automobile body. The electrophoresis coating can provide good adhesion and corrosion resistance; electrophoresis generally adopts a continuous full-immersion treatment method. In order to realize the tilting, turning and other actions of the vehicle body in the tank body, it is necessary to ensure that the vehicle body is fixedly connected with the skid body carrying the vehicle body; at present, the locking method between the vehicle body and the skid body mostly adopts an eccentric lock structure. However, in the eccentric lock structure, the electrophoresis paint is very easy to enter the gap between the pin shaft and the bushing, and it is necessary to clean the eccentric lock structure regularly; how to develop a locking mechanism for the vehicle body and the skid body with a simple structure and no need for maintenance is a problem that needs to be solved on site. Summary of the Invention
[0003] The utility model provides a vehicle body locking mechanism on an electrophoresis skid body, realizing the maintenance-free of the locking mechanism.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A vehicle body locking mechanism on an automobile painting electrophoresis skid body includes an automobile body shell and an electrophoresis skid body plate. The automobile body shell is arranged on the body keel upright posts, and the body keel upright posts are arranged at intervals on the bottom frame beam of the automobile body. A support frame body is arranged on the electrophoresis skid body plate, and the automobile body shell is placed on the support frame body; on the electrophoresis skid body plate directly below the bottom frame beam of the automobile body, a locking mechanism support upright plate frame is arranged, a pin shaft is arranged on the locking mechanism support upright plate frame, a swing arm is hinged on the pin shaft, the middle part of the swing arm is hinged on the pin shaft, a locking hook is connected to the inner side end of the swing arm, the locking hook is movably matched with the bottom frame beam of the automobile body, and a heavy hammer is arranged at the outer side end of the swing arm.
[0006] An electric push rod is arranged on the electrophoresis skid body plate directly below the heavy hammer, and the upward extending shaft of the electric push rod is movably abutted against the heavy hammer.
[0007] The utility model has a simple structure and is convenient to operate, and can be applicable to various working states of the electrophoresis skid body plate. Description of the Drawings
[0008] Figure 1 It is a schematic structural diagram of the locking state of the utility model in the main view direction;
[0009] Figure 2It is a schematic structural diagram of the unlocking state of the present utility model in the front view direction;
[0010] Figure 3 It is a schematic structural diagram of the present utility model in the side view direction. Specific embodiments
[0011] The present utility model will be described in detail below with reference to the accompanying drawings:
[0012] A body locking mechanism on an automotive painting electrophoresis sled body includes an automotive body shell 3 and an electrophoresis sled plate 1. The automotive body shell 3 is arranged on a body keel column 9, and the body keel column 9 is spacedly arranged on a bottom frame beam 8 of the automotive body. A support frame body 2 is arranged on the electrophoresis sled plate 1, and the automotive body shell 3 is placed on the support frame body 2; A locking mechanism support vertical plate frame 4 is arranged on the electrophoresis sled plate 1 directly below the bottom frame beam 8 of the automotive body. A pin shaft 5 is arranged on the locking mechanism support vertical plate frame 4, and a swing arm 6 is hinged on the pin shaft 5. The middle of the swing arm 6 is hinged on the pin shaft 5. A locking hook 7 is connected to the inner end of the swing arm 6, and the locking hook 7 is movably matched with the bottom frame beam 8 of the automotive body. A weight 10 is arranged at the outer end of the swing arm 6. When the weight 10 rises, the swing arm 6 rotates clockwise, and the locking hook 7 disengages from the bottom frame beam 8 of the automotive body. When the weight 10 falls, the swing arm 6 rotates counterclockwise, and the locking hook 7 is buckled on the bottom frame beam 8 of the automotive body.
[0013] An electric push rod 11 is arranged on the electrophoresis sled plate 1 directly below the weight 10, and the shaft extending upward of the electric push rod 11 is movably abutted against the weight 10.
[0014] The construction and working steps of the body locking mechanism on the automotive painting electrophoresis sled body are as follows:
[0015] First step: Four groups of support frame bodies 2 are arranged on the electrophoresis sled plate 1, the automotive body shell 3 is placed on the support frame body 2, a pair of locking mechanism support vertical plate frames 4 are arranged at the front and rear positions of the electrophoresis sled plate 1, a pin shaft 5 is arranged on the locking mechanism support vertical plate frame 4, a swing arm 6 is hinged on the pin shaft 5, a locking hook 7 is arranged at one end of the swing arm 6, a weight 10 is arranged at the other end of the rotating shaft 5, and an electric push rod 11 is arranged below the weight 10;
[0016] Second step: Start the electric push rod 11, make the output shaft extending upward of the electric push rod 11 abut against the weight 10, make the weight 10 rise, the rising swing of the weight 10 makes the swing arm 6 swing around the pin shaft 5, and the locking hook 7 is moved to the inner end position; Through hoisting, the automotive body shell 3 is placed on the support frame body 2, so that the bottom frame beam 8 of the automotive body is arranged directly above the locking mechanism support vertical plate frame 4;
[0017] Step 3: Start the electric push rod 11 again to retract the output shaft that extends upward of the electric push rod 11. The weight 10 loses support and falls downward. The falling and swinging of the weight 10 causes the swing arm 6 to swing reversely around the pin shaft 5, enabling the locking hook 7 to be latched onto the bottom frame beam 8 of the vehicle body. The weight of the weight 10 ensures the locking force between the locking hook 7 and the bottom frame beam 8 of the vehicle body. The four locking mechanisms act simultaneously to achieve the locking of the vehicle body shell 3 and the electrophoresis sled plate 1.
[0018] Step 4: After the electrophoresis of the vehicle body shell 3 is completed, control the output shaft of the electric push rod 11 to extend, jack up the weight 10, cause the swing arm 6 to swing around the pin shaft 5, and release the latching and locking between the locking hook 7 and the bottom frame beam 8 of the vehicle body.
