However, in the automobile welding workshop, the parts of the stamped parts are mainly welded by resistance welding to weld the assembled parts. In the welding process, welding slag splashes everywhere and possibly splashes to a gear or a rack to cause damage, so the gear and the rack are generally arranged in the same horizontal direction, as shown in fig. 2, the gear and the rack are not arranged up and down, and the meshing part of the gear and the rack is designed with the shielding slag to the greatest extent.
Because of the structural limitation, the structure of the conveying trolley is that the motor is arranged above, the gear is arranged below, the gear needs to be arranged on the motor, and the gear is pressed on an output shaft of the motor through a bolt in most of the prior art. However, in a welding workshop, along with the overlong operation time, a small amount of welding slag is inevitably attached to the meshing surface of the gear rack, the service life of the gear is shortened, the gear rack can be blocked in operation and has impact oscillation, the connection between the gear and the motor shaft is realized only through one bolt, although elastic pads are arranged on the bolts, the bolt loosening phenomenon still occurs, and finally the gear is separated from the output shaft of the motor, so that the equipment failure is caused, the production is delayed, and huge economic loss is caused.
In the face of the above problems: 1. in a welding workshop of a white automobile body of an automobile, sparks splash, and welding slag particles can bypass the protective cover and adhere to the meshing surface of the gear and the rack. 2. In the middle and later period of the project, due to the fact that the meshing surface is not smooth, impact shock exists all the time during conveying, and bolts are loosened. 3. After the bolt is loosened, the gear is installed below the motor, and the loosening phenomenon is not easy to find by naked eyes of workshop maintenance personnel. If the bolt loosens and is free of development, the gear can fall off finally, so that the unpowered control of the equipment is caused, and a huge safety accident is caused. In addition, welding slag particles have large and small sizes and cannot be isolated in hundreds of percent, and the problem of gear looseness of the reciprocating conveying trolley in a welding workshop needs to be solved under the working condition, so that under the technical background, an anti-loosening safety device is developed and used for the reciprocating conveying trolley.
