Description

Technical Field

[0001] This utility model relates to the field of gas spring testing technology, specifically a gas spring testing workbench. Background Technology

[0002] A gas spring is an industrial component that provides support, cushioning, braking, height adjustment, and angle adjustment. Its principle involves filling a sealed pressure cylinder with inert gas or an oil-gas mixture, creating a pressure several times or even tens of times higher than atmospheric pressure. The piston rod's movement is achieved by utilizing the pressure difference generated when its cross-sectional area is smaller than the piston's cross-sectional area.

[0003] Patent publication number "CN212621411U" discloses "a gas spring strength testing device, including a frame, a testing cylinder, and a support plate. The testing cylinder is fixedly installed on the upper inner wall of the frame, and a stop block is fixedly connected to the output end of the testing cylinder. A slot is opened on the inner side wall of the frame, and a stop block is provided on the side wall of the support plate. A gas spring fixing device is provided on the upper part of the support plate. The gas spring fixing device includes a square plate, a fixing plate, a clamping plate, a threaded shaft, and a movable limiting plate. The square plate is welded to the upper part of the support plate, and the fixing plate is welded to the upper part of the support plate. The fixing plate has a threaded hole. The clamping plate is slidably disposed on the upper part of the support plate. A bearing seat is provided on the side wall of the clamping plate near the fixing plate. A handle is fixedly connected to one end of the threaded shaft, and the other end of the threaded shaft passes through the threaded hole on the fixing plate and is rotatably connected to the bearing seat. The movable limiting plate is detachably connected to the square plate by bolts."

[0004] In the aforementioned patent, when fixing the gas spring, it uses cylindrical gas springs clamped by parallel straight plates on both sides. In this clamping method, the contact area between the clamping plate and the gas spring is only a small point, which makes the gas spring clamping method relatively unstable, thus affecting subsequent testing steps.

[0005] Therefore, this utility model provides a gas spring testing workbench to solve the above problems. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a gas spring testing workbench. Compared with the prior art, it has the following advantages:

[0015] 1. This gas spring testing workbench, by rotating a knob, drives the first screw, causing the moving plate and clamping blocks to move. This allows for precise adjustment of the clamping block spacing, achieving stable clamping of the gas spring. The internal curvature of the clamping blocks matches the outer wall of the gas spring and features anti-slip grooves, greatly increasing the contact area and friction. This effectively solves the problem of insecure fixing caused by small contact area. The clamping blocks can be easily replaced for different specifications of gas springs, meeting diverse testing needs. Furthermore, frequent replacements are unnecessary when testing the same batch, improving testing efficiency.

[0016] 2. This gas spring testing workbench uses a laser rangefinder to detect the vertical changes of the synchronization plate, thereby detecting the stretching or compression distance of the gas spring. In conjunction with the pulling or compressing force output by the hydraulic cylinder, it can detect the stretching and compression distance of the gas spring under different external forces, thus realizing the testing of the gas spring performance.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1 to 6 This application provides a gas spring testing workbench, including a workbench 1. Vertical rods 5 are fixedly installed at the four corners of the top of the workbench 1. A top plate 4 is fixedly installed between the tops of the vertical rods 5. A testing component 3 is provided at the bottom of the top plate 4. A clamping component 2 is provided at the top of the workbench 1. A bottom hole 7 is opened inside the workbench 1. A gas spring 6 is inserted into the bottom hole 7. The clamping component 2 includes a movable plate 23. The movable plate 23 is slidably connected to the top of the workbench 1. An insert block 29 is fixedly installed on the inner side of the movable plate 23. An outer frame 27 is sleeved on the outer side of the insert block 29. A clamping block 21 is fixedly installed on the inner side of the outer frame 27. An anti-slip groove is opened inside the clamping block 21. The clamping block 21 fits against the outer side of the gas spring 6.

[0028] The insert 29 has a groove 210 inside, and a locking block 28 is slidably connected inside the groove 210. A spring 211 is fixedly installed between the locking block 28 and the inner wall of the groove 210. The side wall of the outer frame 27 has a slot 212, and the locking block 28 is inserted into the corresponding slot 212. The outer end of the locking block 28 is hemispherical, and the hemisphere of the outer end of the locking block 28 is located outside the outer frame 27. A fixed plate 22 is fixedly installed on the top of the workbench 1. A first screw 25 is screwed through the inside of the fixed plate 22. The inner end of the first screw 25 is rotatably connected to the outer side of the moving plate 23. A limit rod 24 is fixedly installed on the outer side of the moving plate 23. The limit rod 24 moves through the inside of the fixed plate 22. A knob 26 is fixedly installed on the outer end of the first screw 25.

[0029] In this embodiment, when fixing the gas spring 6, the first screw 25 is rotated by turning the knob 26. The rotation of the first screw 25 can drive the inner moving plate 23 to move left and right along the top of the workbench 1, thereby driving the inner clamping block 21 to move left and right. The gas spring 6 can be fixed by clamping the two sides of the gas spring 6 with the clamping blocks 21. After fixing, the lower end of the gas spring 6 is inserted into the bottom hole 7. The inner curvature of the clamping block 21 is the same as the outer curvature of the gas spring 6. The clamping block 21 is completely attached to the outer wall of the gas spring 6. The clamping effect is greatly improved by increasing the contact area. The anti-slip groove opened inside the clamping block 21 further improves the clamping stability, thereby solving the problem of weak fixing due to small contact.

[0030] Furthermore, when the gas spring 6 is fixed, the bottom of the gas spring 6 is flush with the bottom of the support leg of the industrial table 1, so that the bottom of the gas spring 6 contacts the ground, ensuring that the gas spring 6 will not move downward when it is squeezed.

[0031] When fixing a gas spring 6 that is not up to standard, by pressing the locking blocks 28 on both the upper and lower sides, the locking blocks 28 are pressed into the groove 210, which moves the locking blocks 28 into the groove 212, thereby releasing the fixation between the outer frame 27 and the insert block 29. With the help of the outer hemisphere, the insert block 29 can be moved out of the outer frame 27, thereby disassembling the clamping block 21. After disassembly, the outer frame 27 with a clamping block 21 of different specifications is replaced and reinstalled on the insert block 29. During installation, the locking blocks 28 are first squeezed. When they reach the groove 212, the spring 211 re-inserts the locking blocks 28 into the groove 212, thus replacing the clamping block 21. The replaceable clamping block 21 allows for the effective clamping of gas springs 6 of different specifications. Moreover, the specifications of gas springs 6 in the same batch are generally the same. Therefore, the clamping block 21 will not be replaced continuously during continuous testing. It is only necessary to replace the clamping block 21 when replacing a batch of gas springs 6.

[0032] Reference Figures 1 to 6In one aspect of this embodiment, the detection component 3 includes a hydraulic cylinder 31, which is fixedly mounted on the top of the top plate 4. The output end of the hydraulic cylinder 31 extends through the interior of the top plate 4. A lifting plate 32 is fixedly mounted at the bottom of the output end of the hydraulic cylinder 31. A connecting plate 33 is fixedly mounted at the bottom of the lifting plate 32. A second screw 34 is fixedly mounted on the front of the connecting plate 33. The second screw 34 is inserted into a hole at the top of the gas spring 6. A nut 35 is screwed onto the outside of the second screw 34 and fits against the top front of the gas spring 6. A synchronization plate 36 is fixedly mounted on the outside of the lifting plate 32. A laser rangefinder 37 is fixedly mounted at the bottom of the top plate 4 and is located directly above the synchronization plate 36.

[0033] In this embodiment, when testing the compression and tensile performance of the gas spring 6, the second screw 34 is inserted into the mounting hole at the top of the gas spring 6, and the connecting plate 33 is fixed to the top of the gas spring 6 by screwing the nut 35 onto the outside of the second screw 34. Then, the hydraulic cylinder 31 is extended and retracted, which drives the lifting plate 32 to move up and down. By moving the lifting plate 32 up and down, the gas spring 6 can be stretched or compressed. During stretching and compression, the laser rangefinder 37 detects the up and down changes of the synchronous plate 36, which can detect the stretching or compression distance of the gas spring 6. In conjunction with the pulling or compressing force output by the hydraulic cylinder 31, the compression distance of the gas spring 6 after stretching under different external forces can be detected, thereby realizing the testing of the performance of the gas spring 6. The pressure sensor is installed in the pipeline of the hydraulic system of the hydraulic cylinder 31. When the hydraulic rod works, the pressure sensor will convert the pressure signal it senses into an electrical signal, and then transmit the signal to the monitoring equipment or control system through cable or wireless transmission, so as to detect the magnitude of the force output by the hydraulic cylinder 31 in real time.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle: When fixing the gas spring 6, rotating the knob 26 drives the first screw 25 to rotate, causing the inner moving plate 23 to move left and right along the top of the workbench 1, thereby driving the inner clamping block 21 to move. The gas spring 6 is clamped by the clamping blocks 21 on both sides, and the lower end of the gas spring 6 is inserted into the bottom hole 7. The inner curvature of the clamping block 21 is consistent with the outer wall of the gas spring 6, increasing the contact area to improve the clamping effect. The internal anti-slip groove further stabilizes the clamping. When the gas spring 6 is fixed, the bottom is flush with the bottom of the bottom support leg of the industrial table 1 to prevent it from shifting downwards when squeezed. For gas springs 6 of different specifications, press the upper and lower side locking blocks 28 to move them into the locking slot 212, release the fixing of the outer frame 27 and the insert block 29, remove the insert block 29 to disassemble the clamping block 21, and replace the outer frame 27 of the clamping block 21 with one of different specifications. The clamp 28 is replaced by re-inserting the clamp 212 with the help of the spring 211. The clamp 21 only needs to be replaced when the batch of gas springs 6 is changed. When testing the performance of the gas spring 6, the second screw 34 is inserted into the mounting hole at the top of the gas spring 6, and the connecting plate 33 is fixed to the top of the gas spring 6 with the nut 35. The hydraulic cylinder 31 is extended and retracted to drive the lifting plate 32 to move up and down to stretch or compress the gas spring 6. The laser rangefinder 37 is used to detect the change of the synchronous plate 36 to obtain the stretching or compressing distance of the gas spring 6. The performance test is achieved by combining the output force of the hydraulic cylinder 31. At the same time, the pressure sensor is installed in the hydraulic system pipeline of the hydraulic cylinder 31 to convert the pressure signal into an electrical signal and transmit it to the monitoring equipment or control system to detect the magnitude of the output force of the hydraulic cylinder 31 in real time.
