Once the tension of the spring coil is within acceptable limits, testing stops. However, these technologies cannot detect the maximum tension of the spring coil or clearly determine its maximum tolerance range. Therefore, existing technologies have certain drawbacks.
[0003] In view of this, this utility model is proposed. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0018] like Figure 1 As shown, a spring coil tension testing device includes: An expansion device includes a partition plate 11. Two sets of threaded rods 19 are provided on the top wall of the partition plate 11. Each set of threaded rods 19 consists of two rods. The two threaded rods 19 are fixedly connected and their thread directions are opposite. A top cover 10 is fixedly installed on the top wall of the partition plate 11. A limiting frame 16 is fixedly installed on the top wall of the cavity of the top cover 10. A bottom plate 13 is provided below the partition plate 11. A worktable 22 is movably installed in the cavity of the bottom plate 13. The cleaning device includes a rotating rod 26, with a connecting rod 27 fixedly installed on both the left and right sides of the rotating rod 26. Two drive blocks 24 are provided below the worktable 22, and an electric cylinder 15 is provided below each of the two drive blocks 24. Four support rods 14 are fixedly installed in a circular array on the bottom wall of the base plate 13. A crossbar 25 is provided below the electric cylinder 15, and both ends of the crossbar 25 are fixedly connected to the corresponding support rods 14.
[0019] In practical use, the expansion device can drive the translation block 18 to move through two sets of threaded rods 19. The movement of the translation block 18 drives the drive rod 20 to move, and the movement of the drive rod 20 opens the spring coil to test the tension of the spring coil. The cleaning device can clean the top of the workbench 22 in time after the spring coil breaks, so as to facilitate the next operation quickly.
[0020] In summary, by setting up an expansion device and a cleaning device, the spring coil can be continuously expanded by the expansion device to test its tension, and the top wall of the workbench 22 can be quickly cleaned by the cleaning device, allowing for a quick start to the next operation.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom wall of the limiting frame 16 is in a cross-shaped hollow state, and a first motor 17 is fixedly installed on each of the two side walls of the top cover 10. Both first motors 17 are located in the cavity of the limiting frame 16, and the output ends of the two first motors 17 are fixedly connected to one end of the corresponding two groups.
[0022] Each of the four chambers of the limiting frame 16 is provided with a translation block 18, and each set of threaded rods 19 passes through two corresponding translation blocks 18. A drive rod 20 is fixedly installed on the bottom wall of each of the multiple translation blocks 18, and the inner side wall of the limiting frame 16 is in contact with the side wall of the translation block 18.
[0023] A through hole 21 is provided on the top wall of the partition plate 11. The through hole 21 is cross-shaped, and multiple drive rods 20 pass through the through hole 21. A baffle 12 is fixedly installed on the top wall of the base plate 13. The first motor 17 is electrically connected to the power supply and switch.
[0024] In practical use, when the output end of the first motor 17 rotates, it drives the threaded rod 19 to rotate. The rotation of the threaded rod 19 drives the translation block 18 to move. The translation block 18 cannot move due to the limitation of the limit frame 16. Since the thread directions of the two corresponding threaded rods 19 are opposite, the two corresponding translation blocks 18 can move away from or towards each other. The movement of the translation block 18 drives the drive rod 20 to move. Before use, all drive rods 20 are located inside the spring coil. The spring coil is continuously expanded by moving away from each other. During use, the operator needs to place the spring coil on the top wall of the workbench 22. As the workbench 22 moves, the front and rear side walls of the spring coil abut against the partition plate 11 and the workbench 22 respectively. This prevents the spring coil from detaching from the drive rod 20 due to elasticity during the expansion process. In the event of spring coil breakage, the baffle plate 12, partition plate 11 and workbench 22 can provide protection. The top cover 10 can limit the position of the limit frame 16 and also protect the threaded rod 19.
[0025] In summary, by setting up a top cover 10, a partition plate 11, a baffle 12, a limit frame 16, a first motor 17, a translation block 18, a threaded rod 19, a drive rod 20, and a worktable 22, the spring coil can be continuously expanded by moving the drive rod 20, thereby testing its tension. It can also prevent the spring coil from detaching from the drive rod 20 and protect against the breakage of the spring coil.
[0026] like Figure 5 and Figure 6 As shown, the electric cylinder 15 is fixedly installed on the top wall of the crossbar 25. The movable end of the electric cylinder 15 is fixedly connected to the bottom wall of the drive block 24. A vertical plate 23 is fixedly installed on the top wall of each of the two drive blocks 24, and a second motor 28 is fixedly installed on one side wall of one vertical plate 23.
[0027] The rotating rod 26 is fixedly installed on the bottom wall of the workbench 22, and the two connecting rods 27 pass through the corresponding driving block 24 and are movably connected to the passing part of the driving block 24.
[0028] The output end of the second motor 28 is fixedly connected to the connecting rod 27 on one side, while the connecting rod 27 on the other side is rotatably connected to the corresponding upright plate 23. Both the second motor 28 and the electric cylinder 15 are electrically connected to the power supply and switch.
[0029] In practical use, the support rod 14 can limit the horizontal bar 25, which in turn limits the electric cylinder 15. When the movable end of the electric cylinder 15 moves up and down, it drives the drive block 24 to move up and down. The up and down movement of the drive block 24 can then drive the rotating rod 26 to move up and down via the connecting rod 27. The up and down movement of the rotating rod 26 can then drive the worktable 22 to move up and down. When the worktable 22 is at the bottom, the operator can place the spring ring on the worktable 22. The rotation of the output end of the second motor 28 can then drive the connecting rod 27 to rotate. The rotation of the connecting rod 27 can then drive the rotating rod 26 to rotate. The rotation of the rotating rod 26 can then drive the worktable 22 to rotate. When the worktable 22 is at the bottom, debris on the top wall of the worktable 22 can be discharged. The operator can place a container under the worktable 22 to collect debris. The upright plate 23 can limit the movement of the second motor 28 and the connecting rod 27.
[0030] In summary, by setting up a support rod 14, an electric cylinder 15, a worktable 22, a vertical plate 23, a drive block 24, a crossbar 25, a rotating rod 26, a connecting rod 27, and a second motor 28, the worktable 22 can be moved up and down by the operation of the movable end of the electric cylinder 15 and the rotation of the output end of the second motor 28, thereby performing the operations of placing spring rings and removing debris.
