Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a high-strength compression and tension spring. Background Technique

[0002] A spring is usually wound by spring wire. When a spring is subjected to an external force, it will deform and store energy; when the external force disappears, the spring will return to its original state by virtue of its own elasticity and release energy. It is the most common type of spring and can be divided into compression springs, tension springs and torsion springs.

[0003] In the existing spring production, it is necessary to conduct endurance pressure tests on them to detect whether they meet the standards. When conducting large-scale inspections, different springs need to be tested. During the test, tensile and compression tests are carried out. After the tensile test is completed, the compression test is uniformly carried out. The process is very troublesome and time-consuming. Therefore, a high-strength compression and tension spring is needed. Content of the Utility Model

After the tensile test is completed, the compression test is uniformly carried out. The process is very troublesome and time-consuming. To achieve the above purpose, the utility model provides the following technical solution: A high-strength compression and tension spring, including a fixed circular block, a disassembly component is arranged on the top of the fixed circular block. The disassembly component includes a positioning block, the positioning block is fixedly connected to the top of the fixed circular block, a moving rod is movably connected to one side of the positioning block, the other end of the moving rod is fixedly connected to a clamping plate, a chute is opened on one side of the clamping plate, and a first fixing bolt is movably connected inside the clamping plate. The setting of the disassembly component is that after the placement plate is placed into the placement groove from one side of the positioning block, the clamping plate on one side is moved towards the placement plate through the first fixing bolt, the moving rod moves into the positioning block, and then the placement plate is fixed. When disassembling, just operate in the reverse direction, effectively conduct the tensile strength test on the spring body, ensure the strength and endurance of the spring body. Then, when it is necessary to conduct a compression test on the spring body, disassemble the hook part to compress the spring body, which is more convenient and efficient and improves the working efficiency of testing the spring body.

[0005] Further preferably, a spring body is fixedly connected to the bottom of the fixed circular block, and a second fixing bolt is movably connected to the top of the positioning block. The second fixing bolt fixes and limits the placement plate after it is placed, ensuring that the placement plate will not slide out and affect the tensile and compression tests of the spring body, and improving the overall stability.

[0006] Further preferably, a groove is opened on the top of the positioning block, and a placement groove is opened on the top of the positioning block. The groove enables the clamping plate to move on the top to fit the whole.

[0007] Further preferably, a convex block is slidably connected to the inner wall of the chute. A connection hole is formed at the top of the convex block. The convex block can be fixed and limited in the chute to ensure that it will not fall off during the stretching process, and the connection hole is adapted to the fixing bolt II to maintain stability.

[0008] Further preferably, a placement plate is fixedly connected to one side of the convex block. A position block is fixedly connected to the top of the placement plate. A hook is fixedly connected to the top of the position block. The hook drives the fixed round block at the bottom to stretch the spring body, which is more convenient.

After placing the placement plate into the placement groove from one side of the position block, the clamping plate on one side is moved towards the placement plate through the fixing bolt I, and the moving rod moves into the positioning block, and then the placement plate is fixed. During disassembly, the reverse operation can be performed, effectively testing the stretching degree of the spring body, ensuring the strength and endurance of the spring body. When it is necessary to perform a compression test on the spring body later, the hook part is disassembled to compress the spring body, which is more convenient and efficient, improving the working efficiency of testing the spring body.
