Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spring testing machines, in particular to a spring shock-absorbing durability testing machine. Background Art
[0002] The spring testing machine is an instrument specially used to test springs. After the spring is manufactured, its performance will be tested, such as its durability. This testing machine is used to test the tolerance of the spring when it is subjected to force and deformation.
[0003] The spring has the ability to deform. When testing the durability of the spring, the spring will be compressed and then contacted and compressed to observe whether the spring can completely return to its original position and check the durability of the spring. Conventional testing machines use a screw to drive the pressure plate to move down and press down on the top of the spring to squeeze the spring. This method will cause the spring to always be under a constant force pressure. When the spring is in use, it often bounces back and forth under a load-bearing state, and the force it is subjected to changes in a short period of time. The ordinary screw-driven pressure plate pressing down spring testing method cannot apply a large force to the spring in a short period of time, resulting in a difference between the testing environment and the actual use environment of the spring.

The pillar 4 can be disassembled by rotating the pillar 4, which is convenient for removing and replacing the pillar 4. The spring is sleeved on the outside of the pillar 4 to simply limit the spring to prevent it from tipping over. The bearing seat 2 supports the bottom end of the spring, and the top end of the spring contacts the base 10. After the base 10 moves down, the spring is deformed and compressed, and the durability of the spring is tested. The screw 8 is used to assemble the base frame 1 and the side seat 6. Conversely, the base can be disassembled. Frame 1, side seat 6, after disassembling the bottom frame 1 and side seat 6, the side seat 6 is in a free fall state. At this time, the top of the side seat 6 is centered on the screw rod 9, and a group of counterweights are sleeved. The side seat 6 is manually lifted, and then the side seat 6 is released to make it fall freely. A variable force is applied to the spring for a short time, so that the spring simulates the force and deformation in the actual use environment, which is convenient for more thorough testing of the durability of the spring. The sleeve 15 is made of rubber material and is used to simply protect the central hollow counterweight sleeved on the outside of the top rod 13 and the top column 14. The top rod 13 and the top column 14 rotate with each other, and the top rod 13 and the top column 14 are extended to sleeve more groups of counterweights.

The spring is sleeved on the outside of the support 4, and a simple limit is imposed on the spring to prevent it from tipping over. The bearing seat 2 supports the bottom end of the spring, and the top end of the spring contacts the base 10. After the base 10 moves down, the spring is deformed and compressed, and the durability of the spring is tested. The screw 8 is used to assemble the base frame 1 and the side seat 6. Conversely, the base frame 1 and the side seat 6 can be disassembled. After disassembling the base frame 1 and the side seat 6, the side seat 6 is in a free fall state. At this time, a group of counterweights are sleeved on the top of the side seat 6 with the screw 9 as the center. The side seat 6 is manually supported, and then the side seat 6 is released to allow it to fall freely. A variable force is applied to the spring for a short time, allowing the spring to simulate a real In the actual use environment, the force and deformation it is subjected to are convenient for more thorough testing of the durability of the spring. The sleeve 15 is made of rubber material and is used to simply protect the central hollow counterweight block sleeved on the outside of the top rod 13 and the top column 14. The top rod 13 and the top column 14 rotate, and the top rod 13 and the top column 14 are extended to sleeve more groups of counterweight blocks. Conversely, the top rod 13 and the top column 14 are shortened to sleeve a small number of counterweight blocks, which is more flexible and convenient to use. By rotating the screw rod 9, the screw rod 9 moves downward, causing the base 10 to move downward and press on the top of the spring, applying a constant force to the spring to test the durability of the spring. When the base 10 moves downward, one of the side blocks 11 moves with the slide 12 to make the base 10 more stable when displaced.
