[0002] A gas spring is an industrial component that can provide support, cushioning, braking, height adjustment, and angle adjustment.

[0003] When a gas spring is dropped from a height onto the ground, check if its joints are loose.

[0004] Inspection work is usually carried out manually, which requires people to keep going back and forth, increasing the physical labor intensity of the operators. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gas spring testing fixture that can reduce the physical labor intensity of operators while improving work efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A gas spring testing fixture includes a fixture body, the fixture body including a housing, four guide rods fixedly disposed on the top of the housing, a sliding plate slidably sleeved on the four guide rods, a connecting rope fixedly disposed on the bottom of the sliding plate, and the other end of the connecting rope passing through the housing and connected to a gas spring.

[0008] The top of the housing is equipped with a test assembly;

[0009] The test assembly includes a vertical plate, on which a sliding block is slidably mounted. A solenoid valve is fixedly mounted at one end of the sliding block. The solenoid valve is always located directly above the sliding plate. The sliding plate is lifted or released by activating or deactivating the solenoid valve.

[0010] In a preferred embodiment, the present invention can be further configured such that the test component further includes a moving mechanism, which drives the sliding block to move.

[0011] The moving mechanism includes a first fixed rod, which is fixed to the top of the housing. A screw is rotatably sleeved on the outer circumferential surface of the first fixed rod. The screw passes through the sliding block and is threadedly connected to the sliding block.

[0012] A placement plate is fixedly installed on the top of the upright plate, and a motor is fixedly installed on the top of the placement plate. The output end of the motor passes through the placement plate and is fixed to one end of the screw.

[0013] In a preferred embodiment, the present invention can be further configured such that: a first through hole is provided on one side of the upright plate, the sliding block passes through the first through hole, and the sliding block is slidably connected to the upright plate.

[0014] In a preferred embodiment, the present invention can be further configured such that a rubber plate is slidably sleeved on the lower half of the outer peripheral surface of each guide rod.

[0015] Each of the guide rods is fitted with a spring on its outer circumference, and the two ends of the spring are respectively fixed to the bottom of the corresponding rubber plate and the top of the housing;

[0016] When all four springs are in their natural state, the four rubber plates are on the same horizontal plane.

[0017] In a preferred embodiment, the present invention can be further configured such that: one side of the housing is open, and a contact plate is placed at the bottom of the inner wall of the housing.

[0018] In a preferred embodiment, the present invention can be further configured such that: two first sliding grooves are symmetrically formed on one side of the housing, and the tops of the two first sliding grooves penetrate the bottom of the inner wall of the housing;

[0019] Two placement blocks are symmetrically arranged at the bottom of the contact plate, and the placement blocks are located in the corresponding first groove;

[0020] Each of the two placement blocks is provided with a handle at one end near the opening of the housing.

[0021] In a preferred embodiment, the present invention can be further configured such that: a second placement groove is provided on the side of the contact plate near the back plate of the housing, and a magnet is provided in the second placement groove.

[0022] In summary, this utility model has at least one of the following beneficial technical effects:

[0023] 1. By setting up a testing component, a sliding plate is moved by a solenoid valve, and the sliding plate moves the connecting rope. When the solenoid valve is opened, the gas spring is suspended in the upper half of the housing. When the solenoid valve is closed, the gas spring falls to the bottom of the inner wall of the housing, thereby detecting the quality of the gas spring. The mechanized component replaces manual inspection, reducing the physical labor intensity of operators and improving work efficiency.

[0024] 2. By setting rubber blocks on all four guide rods and installing springs between the rubber blocks and the housing, the contact between the sliding plate and the housing is prevented through the rubber blocks and springs. This not only reduces the impact force generated by the sliding plate falling, but also improves the service life of the housing and the sliding plate.

[0025] 3. By incorporating a first chute and a placement block, operators can more easily and quickly change contact plates of different hardness, making the testing more comprehensive.

[0026] 4. By providing a second placement groove on one side of the contact plate, and placing a magnet in the second placement groove, the position of the contact plate is more fixed. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example:

[0032] Reference Figure 1-Figure 2 As shown, the present invention discloses a gas spring 51 testing fixture, including a fixture body 1, which includes a housing 11. The housing 11 has an opening on one side.

[0033] Four guide rods 12 are fixedly mounted on the top of the housing 11. A sliding plate 13 is slidably mounted on the four guide rods 12. A connecting rope 14 is fixedly mounted on the bottom of the sliding plate 13, and the other end of the connecting rope 14 passes through the housing 11 and is connected to a gas spring 51. The opening at the top of the housing 11 is large enough to allow the gas spring 51 to pass through the opening at the top of the housing 11 and move to the top of the housing 11.

[0034] A test assembly 2 is mounted on the top of the housing 11. The test assembly 2 includes a vertical plate 21, on which a sliding block 22 is slidably mounted. A first through hole 4 is provided on one side of the vertical plate 21, through which the sliding block 22 passes, and the sliding block 22 is slidably connected to the vertical plate 21. A solenoid valve 23 is fixedly mounted on one end of the sliding block 22, and the solenoid valve 23 is always located directly above the sliding plate 13. The solenoid valve 23 does not contact the four guide rods 12 during movement.

[0035] Test component 2 also includes a moving mechanism 3, which drives the sliding block 22 to move.

[0036] The moving mechanism 3 includes a first fixed rod 31, which is fixed to the top of the housing 11. A screw 32 is rotatably sleeved on the outer circumferential surface of the first fixed rod 31. The screw 32 passes through the sliding block 22 and is threadedly connected to the sliding block 22.

[0037] A placement plate 33 is fixedly installed on the top of the upright plate 21, and a motor 34 is fixedly installed on the top of the placement plate 33. The output end of the motor 34 passes through the placement plate 33 and is fixed to one end of the screw 32.

[0038] The sliding plate 13 is raised or lowered by activating or deactivating the solenoid valve 23. The sliding plate 13 is made of a material that is easily attracted by magnets, such as iron.

[0039] A rubber plate 5 is slidably fitted onto the lower half of the outer circumference of each guide rod 12. A spring 51 is fitted onto the outer circumference of each guide rod 12, with both ends of the spring 51 fixed to the bottom of the corresponding rubber plate 5 and the top of the housing 11, respectively. When all four springs 51 are in their natural state, the four rubber plates 5 are on the same horizontal plane.

[0040] A contact plate 6 is placed at the bottom of the inner wall of the housing 11. Two first sliding grooves 7 are symmetrically formed on one side of the housing 11, and the tops of the two first sliding grooves 7 penetrate the bottom of the inner wall of the housing 11. Two placement blocks 71 are symmetrically arranged at the bottom of the contact plate 6, and the placement blocks 71 are located in the corresponding first sliding grooves 7. A handle 72 is provided at the end of each placement block 71 near the opening side of the housing 11.

[0041] A second placement groove 8 is provided on the side of the contact plate 6 near the back plate of the housing 11, and a magnet 81 is provided in the second placement groove 8. The back plate of the housing 11 is also made of a material that is easily attracted by magnets.

[0042] The implementation principle of the above embodiments is as follows:

[0043] Before starting the test, the operator first places the contact plate 6 in the appropriate position. After the two placement blocks 71 are placed in the corresponding first slide groove 7, the operator pushes the contact plate 6 forcefully so that the side of the contact plate 6 away from the opening of the housing 11 contacts the back plate of the housing 11, so that the magnet 81 attracts the back plate, thereby further fixing the position of the contact plate 6.

[0044] The operator connects one end of the connecting rope 14 to one end of the gas spring 51 to be tested. At this time, the sliding plate 13 is in contact with the four rubber plates 5.

[0045] Next, the operator connects the power supply and starts the solenoid valve 23 and the motor 34. The motor 34 starts to rotate, which drives the screw 32 to rotate. The screw 32 drives the sliding block 22 to move, and the sliding block 22 drives the solenoid valve 23 to move towards the sliding plate 13.

[0046] When the solenoid valve 23 comes into contact with the sliding plate 13, the sliding plate 13 is attracted by the solenoid valve 23.

[0047] Under the control of the PLC (not shown in the figure), the PLC is electrically connected to the motor 34 and the solenoid valve 23.

[0048] Motor 34 begins to reverse. After motor 34 drives sliding block 22 to its initial position, sliding block 22 drives solenoid valve 23 to its initial position. Solenoid valve 23 then drives sliding plate 13 to move, positioning sliding plate 13 directly above housing 11. At this time, connecting rope 14 is taut, and gas spring 51 is suspended above the interior of housing 11.

[0049] Next, the PLC closes the solenoid valve 23, and under its own gravity, the sliding plate 13 moves downward and the gas spring 51 also moves downward.

[0050] The gas spring 51 contacts the contact plate 6. The sliding plate 13 contacts the four rubber blocks. It should be noted that when the sliding plate 13 contacts the four rubber blocks and the gas spring 51 lies flat on the contact plate 6, the connecting rope 14 is in a slack state.

[0051] The drop resistance of the gas spring 51 was observed through repeated experiments. Alternatively, the contact plate 6 was replaced to test the drop resistance of the gas spring 51 after it came into contact with objects of different hardness.

[0052] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
