[0006] The spring quality testing device provided in this application adopts the following technical solution: it includes a base plate, an operating table is fixedly connected to the top of the base plate, and a testing device is fixedly connected to the top of the operating table;
[0007] The bottom of the operating table is connected to a motor, the top output end of the motor is fixedly connected to a rotating column, the top of the rotating column is fixedly connected to a rotating disk, the top of the rotating disk is provided with an arc-shaped sliding groove, the inner wall of the arc-shaped sliding groove is slidably connected to a sliding column, and a gripper is provided above the sliding column.
[0008] Optionally, a testing table is fixedly connected to the top of the operating table, and a moving groove is provided on the top of the testing table.
[0009] Optionally, a sliding block is fixedly connected to the top of the sliding column, the outer wall of the sliding block is slidably connected to the inner wall of the moving groove, and the top of the sliding block is fixedly connected to the bottom of the gripper.
[0010] Optionally, the number of arc-shaped sliding grooves is several, and the several arc-shaped sliding grooves are arranged in a circular array; the number of grippers is several, and the several grippers are arranged in a circular array.
[0011] Optionally, a sealing box is fixedly connected to the top of the operating table, and a push plate is slidably connected to the inner wall of the sealing box.
[0012] Optionally, an air intake check valve is fixedly connected to the right side of the push plate, a connecting pipe is fixedly connected to the left side of the sealing box, and an air jet is fixedly connected to the bottom of the connecting pipe on the side away from the sealing box.
[0013] Optionally, there are several sliding columns arranged in a circular array. A movable rod is fixedly connected to the outer wall of the sliding column on the right side, and the side of the movable rod away from the sliding column is fixedly connected to the right side of the push plate.
[0014] In summary, this application includes the following beneficial technical effects:
[0015] 1. This utility model is equipped with components such as a motor, a rotating disk, and an arc-shaped sliding groove. When the motor drives the rotating disk to rotate, the arc-shaped sliding groove drives the sliding column to slide, causing multiple grippers arranged in a ring array to move closer or further away synchronously. It can accommodate springs of different diameters. During the clamping process, the dual guiding effect of the sliding column and the arc-shaped sliding groove, as well as the sliding block and the moving groove, ensures that the grippers move smoothly and achieves a firm fixation of the spring. This avoids spring displacement and misalignment during testing, thus ensuring the accuracy of the test data.
[0016] 2. This utility model, by incorporating components such as a sealed box, a push plate, and an air inlet check valve, allows several sliding columns to move outwards after the spring test is completed and the spring is removed. The restart of motor one causes these sliding columns to move synchronously, with the rightmost sliding column driving a moving rod. Simultaneously, the moving rod drives the push plate to slide to the right, filling the sealed box with gas. The reciprocating movement of the sliding columns causes the push plate to blow the gas from the sealed box through a connecting pipe from the air jet head, cleaning any residue remaining on the top of the testing table. This eliminates the need for manual intervention, improving cleaning efficiency and ensuring the cleanliness of the testing table surface. It provides a stable reference surface for subsequent spring testing, effectively enhancing testing accuracy. Attached Figure Description

[0024] In this embodiment, a motor 2 is connected to the bottom of the operating table 11. A rotating column 21 is fixedly connected to the top output end of the motor 2. A rotating disk 211 is fixedly connected to the top of the rotating column 21. An arc-shaped sliding groove 212 is provided on the top of the rotating disk 211. The arc-shaped sliding groove 212 can drive several grippers 24 to synchronously contract or extend when it rotates. A sliding column 23 is slidably connected to the inner wall of the arc-shaped sliding groove 212. A gripper 24 is provided above the sliding column 23.
[0025] Please see Figure 4 As shown, a sealing box 3 is fixedly connected to the top of the operating table 11, and a push plate 31 is slidably connected to the inner wall of the sealing box 3.
[0026] Please see Figure 2 As shown, a testing table 22 is fixedly connected to the top of the operating table 11. A moving groove 221 is provided on the top of the testing table 22. The moving groove 221 can restrict the sliding block 231 and prevent it from shifting or misaligning.
[0027] Please see Figure 4 As shown, an intake check valve 311 is fixedly connected to the right side of the push plate 31. The intake check valve 311 is closed when the push plate 31 moves to the left and open when the push plate 31 moves to the right. A connecting pipe 33 is fixedly connected to the left side of the sealed box 3. An air jet head 34 is fixedly connected to the bottom of the side of the connecting pipe 33 away from the sealed box 3. The sealed box 3 and the push plate 31 are sealed together.
[0028] Please see Figure 3 As shown, a sliding block 231 is fixedly connected to the top of the sliding column 23. The outer wall of the sliding block 231 is slidably connected to the inner wall of the moving groove 221. The top of the sliding block 231 is fixedly connected to the bottom of the gripper 24.
[0029] Please see Figure 4 As shown, there are several sliding columns 23 arranged in a circular array. A moving rod 32 is fixedly connected to the outer wall of the sliding column 23 on the right side. The side of the moving rod 32 away from the sliding column 23 is fixedly connected to the right side of the push plate 31.
[0030] Please see Figure 2 As shown, there are several arc-shaped sliding grooves 212, which are arranged in a circular array. There are also several grippers 24, which are arranged in a circular array.
[0031] The implementation principle of the spring quality testing device in this application embodiment is as follows: After placing the spring to be tested in the clamping area on the testing table 22, the motor 2 is started. The output end of the motor 2 drives the rotating column 21 and the rotating disk 211 to rotate. When the rotating disk 211 rotates, the arc-shaped sliding groove 212 at its top guides the sliding column 23, causing the sliding column 23 to slide along the inner wall of the arc-shaped sliding groove 212. At the same time, the sliding block 231 at the top of the sliding column 23 slides synchronously in the moving groove 221 of the testing table 22. Since the multiple grippers 24 are arranged in a circular array and correspond to the sliding column 23, the sliding of the sliding column 23 will drive the grippers 24 to move towards the center or away from the outside synchronously. When the grippers 24 are in close contact with the outer wall of the spring, the spring can be stably clamped and fixed, which facilitates subsequent testing operations. After the spring testing is completed... After removal, restarting motor 2 causes several sliding columns 23 to move outward. At this time, the rightmost sliding column 23 will drive the moving rod 32 to move synchronously. While moving, the moving rod 32 will drive the push plate 31 to slide to the right. At this time, the air intake check valve 311 is open, filling the sealed box 3 with gas. When the rightmost sliding column 23 retracts inward, it will drive the moving rod 32 to move synchronously to the left. While moving to the left, the moving rod 32 will drive the push plate 31 to push the gas in the sealed box 3 to move. At this time, the air intake check valve 311 is closed. The reciprocating movement of several sliding columns 23 will cause the push plate 31 to blow the gas in the sealed box 3 out of the jet head 34 through the connecting pipe 33, cleaning the residue remaining on the top of the test table 22.
[0032] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
