Description

Technical Field

[0001] The utility model relates to the technical field related to automobile parts processing, in particular to an automobile spring safety assembly device. Background Art

[0002] The shock absorber is an indispensable component in the vehicle suspension system. Its main function is to slow down the expansion and compression speed of the spring and absorb the vibration caused by it. When the spring is deformed, it can stabilize quickly, thereby improving the riding comfort of the driver and passengers. The components of the shock absorber include the shock absorber cylinder, shock absorber piston, shock absorber spring, etc.

[0003] During the assembly process of the shock absorber, the lower cover needs to be supported, and then the spring is placed on the outside of the piston, and the upper cover is driven down by the pressure device. The staff then installs the bolts on the upper cover to complete the assembly of the spring. However, since the loading and unloading of the shock absorber are all done manually, it is inevitable that the shock absorber cylinder will not be installed properly during manual loading, resulting in the cylinder being skewed. If the spring is installed in this case, it is easy to cause the shock absorber to deform and be damaged, and the shock absorber with a skewed cylinder is extremely easy to pop out and cause impact damage to the staff.

[0022] (2) The hydraulic cylinder drives the T-shaped pressure plate to descend, so that the T-shaped pressure plate squeezes the upper cover and compresses the spring. Then, the worker can install the bolt on the piston through the working port on the T-shaped pressure plate to complete the installation of the spring. Since the installation of the bolt is also manually operated, during the descent of the T-shaped pressure plate, the two ends of the rotating rod will rotate on the ear plate and the protective plate at the bottom of the T-shaped pressure plate respectively. At this time, the inclined rotating rod will drive the two sets of protective plates to approach each other, so that the spring is shielded when the spring is compressed. In this way, the worker can avoid being too close to the spring when installing the bolt, and avoid the deformation of the spring causing the worker's clothes or skin to be pinched, thereby further improving the safety of the spring assembly process.
