Description

Technical Field

[0001] The utility model relates to the technical field related to automobile assembly equipment, in particular to an automobile transmission shaft disassembly and assembly platform. Background Art

[0002] The automobile drive shaft is an important component for transmitting power in the automobile transmission system. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle, so that the car can generate driving force. The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is very important. Generally, the drive shaft must be dynamically balanced before leaving the factory and adjusted on a balancing machine.

[0003] During the assembly process of the drive shaft, since the drive shaft is located under the vehicle chassis and the drive shaft is long and heavy, after the vehicle is lifted, it is necessary to use a lifting device to lift the drive shaft to the bottom of the vehicle chassis. When the universal joints at both ends of the drive shaft are assembled and fixed with bolts, position deviations are inevitable, which will result in the inability to align the mounting holes when tightening the bolts. After the lifting device lifts the drive shaft, it is inconvenient to fine-tune the drive shaft. If the lifting device is moved as a whole, the movement range will be too large. Therefore, the position of the lifting device needs to be adjusted multiple times, which is time-consuming and labor-intensive, affecting the assembly efficiency of the drive shaft. Utility Model Content

[0004] The purpose of the utility model is to provide a disassembly and assembly platform for an automobile transmission shaft, so as to solve the problem raised in the above-mentioned background technology that the universal joints at both ends of the transmission shaft will inevitably have position deviation when they are assembled and fixed with bolts, and it is inconvenient to fine-tune the transmission shaft after the lifting equipment lifts the transmission shaft.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an automobile transmission shaft disassembly and assembly platform, comprising a movable seat,

[0006] A plurality of casters are arranged at the bottom of the movable seat, a support plate is arranged above the movable seat, and a bracket is slidably connected above the support plate, and a limit seat is fixed at both ends of the top of the bracket, and an arc groove is opened on the limit seat;

[0015] In the above technical solution, two sets of screw rods can be used to drive the two sets of movable plates to move closer to or away from each other. When the two sets of movable plates move away from each other, the two ends of the support rod will rotate at the bottom of the movable plate and the support plate respectively, and will drive the support plate to rise to lift the transmission shaft, and the unthreaded sections on the two sets of screw rods can guide the two sets of movable plates respectively.
