Abstract
Description
Technical Field
[0001] This utility model relates to shock absorber assembly equipment, and in particular to a direct-acting spring compressor. Background Technology
[0002] During the assembly of the shock absorber, the spring is already fitted onto the shock absorber. At this time, the upper end of the spring is higher than the position of the shock absorber to be assembled, so that the spring needs to be compressed to expose the position of the shock absorber to be assembled for the operator to assemble. However, it is difficult to compress the spring directly by hand, and springs come in different thicknesses. Therefore, it is proposed to design a spring compressor for thick springs to reduce the assembly difficulty. Utility Model Content
[0003] In view of the technical problems existing in the background art, the present invention aims to provide a direct-acting spring compressor, in which a pressure plate presses down and a clamp pushes up, and the two work together to compress a coarse spring.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This direct-acting spring compressor includes a lower-pressure motor, a pressure plate, a buffer cylinder, and a clamp. The lower-pressure motor is driven and connected to the pressure plate. The pressure plate is raised and lowered. The pressure plate has an opening for the shock absorber body to pass through. The upper surface of the pressure plate is an operating table. The buffer cylinder is driven and connected to the clamp. The clamp is located below the pressure plate. The clamp has a positioning groove for positioning the shock absorber body. An accommodating space for accommodating the spring is formed between the clamp and the pressure plate.
[0005] In this design, the pressure plate is driven to press down by the downward motor. The air chamber in the cylinder compresses to buffer the further downward stroke of the pressure plate. The buffer cylinder applies an upward force to the clamp, and the bidirectional force reliably compresses the coarse spring. The shock absorber body passes through the opening for the operator to assemble, and the operating table is used to place the accessories.
[0006] Preferably, the pressure motor is mounted on the mounting plate, the mounting plate has guide posts on both sides, the pressure plate is connected to an upper guide sleeve, and the upper guide sleeve is sleeved on the guide posts.
[0007] In this design, the guide post and the upper guide sleeve work together to guide the lifting and lowering of the pressure plate.
[0008] Preferably, the clamp is mounted on a movable plate, the movable plate is connected to the buffer cylinder via a transmission, and lower guide sleeves are provided on both sides of the movable plate, the lower guide sleeves being sleeved on the guide post.
[0009] In this design, the guide post and the lower guide sleeve work together to guide the lifting and lowering of the moving plate.
[0010] Preferably, the fixture is provided with a mounting platform below it, the guide post is connected to the mounting platform, the mounting platform is provided with a feeding box, and the buffer cylinder is provided below the mounting platform.
[0011] In this design, the feed box holds the accessories for easy access.
[0012] Preferably, a limiting sleeve is provided below the pressure plate.
[0013] In this design, the limiting sleeve restricts the spring edge from shifting towards the opening, ensuring full contact between the spring and the pressure plate and preventing the spring edge from affecting the assembly of the components.
[0014] Preferably, the fixture includes a positioning seat and a positioning block, the positioning seat and the positioning block are detachably connected, and the positioning block is provided with the positioning groove.
[0015] In this solution, the positioning block is replaced to change the size of the positioning groove to adapt to shock absorbers of different specifications.
[0016] The beneficial effects of this utility model are as follows: the downward-pressing motor drives the pressure plate to press down, and the air chamber in the cylinder compresses to buffer the further downward stroke of the pressure plate. The buffer cylinder applies an upward force to the clamp, and the bidirectional force reliably compresses the coarse spring. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description
