Description

Technical Field

[0001] This utility model relates to the technical field of spring testing equipment, and in particular to a spring testing equipment for spring production. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. It is generally made of spring steel and is widely used in the mechanical field and daily life. After production, springs need to undergo axial pressure testing to check whether they meet industry standards. If the spring quality is substandard, it is easy to be damaged after use, which may lead to equipment damage and pose certain safety hazards.

[0003] However, springs are prone to lateral bending during pressure testing. When subjected to pressure, springs may bend laterally or become unstable, resulting in uneven distribution of test force and even damage to the spring or equipment. They may not be compressed in the vertical direction, thus affecting the test results. In addition, if a spring bends laterally, it may pop out, causing injury to the equipment or test personnel.

[0004] Therefore, how to provide a spring testing device for spring production is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a spring testing device for spring production. The device uses a second driving assembly to drive a clamping plate on a clamping mechanism to fix the outer coil of the spring.

Therefore, the spring under pressure can only undergo axial compression, ensuring a uniform distribution of the test force, preventing the spring from becoming unstable due to lateral bending, ensuring the accuracy of the test results, avoiding spring damage, and improving the safety of spring testing. This addresses the problems mentioned in the background art.

The inner surface of the third sliding groove 21 is adapted to the clamping plate 13. A set of brackets 22 is fixedly connected to the lower surface of the fixed plate 1.

[0024] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the fixing mechanism includes a connecting frame 6, a connecting plate 7, a wedge block 8, a guide groove 9, a guide slider 10, a limiting block 11, a second groove 12, a clamping plate 13, and a second driving assembly. The connecting frame 6 is fixedly connected to the lower surface of the sliding plate 5, the connecting plate 7 is fixedly connected to the lower end of the connecting frame 6, the guide groove 9 is disposed inside the wedge block 8, the guide slider 10 is slidably connected inside the wedge block 8, the clamping plate 13 is fixedly connected to the lower end of the wedge block 8, and the limiting block 11 is fixedly connected to the wedge block 8. The second driving assembly includes a second driving motor 17 and a second screw... The second drive motor 17 is fixedly connected to the upper surface of the sliding plate 5, the second threaded rod 18 is fixedly connected to the output end of the second drive motor 17, the connecting ring 20 is threadedly connected to the second threaded rod 18, the connecting rod 19 is fixedly connected to the outer surface of the connecting ring 20, the end of the connecting rod 19 away from the connecting ring 20 is fixedly connected to the guide slider 10, the inclined surface of the wedge block 8 is slidably connected to the connecting rod 19, the interior of the connecting plate 7 is rotatably connected to the second threaded rod 18, and the interior of the sliding plate 5 is rotatably connected to the second threaded rod 18.

[0025] Working principle: The spring to be tested is placed on the fixed plate 1, so that the spring is located between multiple clamping plates 13. The second drive motor 17 is started, and its output end drives the second threaded rod 18 to rotate. Since the connecting ring 20 is threadedly connected to the second threaded rod 18, the connecting ring 20 will move along the axial direction of the second threaded rod 18. When the connecting ring 20 moves, it drives the guide slider 10 to slide in the guide groove 9 through the connecting rod 19, thereby pushing the wedge block 8 to move. While the wedge block 8 slides on the lower surface of the sliding plate 5 and the upper surface of the connecting plate 7, its inclined surface slides in cooperation with the connecting rod 19, and the clamping plate 13 slides along the second sliding groove 12. Finally, multiple clamping plates 13 converge towards the center, firmly clamping and fixing the spring, limiting the lateral bending of the spring during testing. The first drive motor 16 is started, and its output end drives the first threaded rod 15 to rotate. One of the first sliders 4 is threadedly connected to the first threaded rod 15, and the other first slider 4 is slidably connected to the guide rod 14. The sliding plate 5 moves up and down along the first sliding groove 3 of the column 2 with the first slider 4. The sliding plate 5 drives the fixing mechanism and the spring to move up and down, thereby performing compression or tension testing on the spring to determine whether the elasticity, strength and other properties of the spring meet the requirements.
