As shown in fig. 1 and 2, the gas spring testing device of the utility model comprises a bearing seat 1 with a rectangular structure, a door-shaped bracket 2 is arranged on the top surface of the bearing seat 1, a transmission screw 3 vertically penetrates through the center of the top wall of the door-shaped bracket 2, and the upper end of the transmission screw 3 is in transmission connection with a bidirectional motor 4, so that the transmission screw 3 is driven to rotate forward or reversely along the axis of the transmission screw by the bidirectional motor 4.
A lifting sleeve 5 positioned at the inner side of the portal-shaped bracket 2 is sleeved on the transmission screw 3 in a screwed manner (namely, the lifting sleeve 5 is sleeved on the transmission screw 3 below the cross brace of the portal-shaped bracket 2 in a screwed manner), the length of the lifting sleeve 5 is slightly longer than that of the transmission screw 3 at the inner side of the portal-shaped bracket 2, so that when the upper end of the lifting sleeve 5 sleeved on the transmission screw 3 is propped against the lower surface of the cross brace of the portal-shaped bracket 2, the lower end of the lifting sleeve 5 is still lower than the lower end of the transmission screw 3; at this time, an upper pressing block 6 (as shown in fig. 3) may be fixedly connected to the lower end of the lifting sleeve 5, where the upper pressing block 6 has a plate structure vertically fixedly connected to the lower end surface of the lifting sleeve 5, and is used to push down the gas spring 7 located right below the lifting sleeve 5 under the pushing of the lifting sleeve 5.
In order to ensure that the driving screw 3 can drive the lifting sleeve 5 to ascend or descend when rotating forwards or reversely, instead of the lifting sleeve 5 rotating along with the driving screw 3, a positioning guide plate 8 is horizontally connected to the outer edge of the upper pressing block 6, at least one group of guide rods 9 parallel to the axis of the lifting sleeve 5 are arranged on the positioning guide plate 8 in a penetrating manner, of course, the guide rods 9 are fixedly connected to the bearing seat 1 or the door-shaped bracket 2, specifically, as shown in fig. 3, holes are formed in the central positions of the positioning guide plates 8, the upper pressing block 6 is fixedly embedded in the holes, a pair of through holes are symmetrically formed in the positioning guide plates 8 positioned on the left side and the right side of the upper pressing block 6, the guide rods 9 are vertically and fixedly connected to two groups of transverse support lower surfaces of the door-shaped bracket 2, the lengths of the two groups of guide rods 9 are larger than those of the lifting sleeve 5, and the two corresponding through holes on the self-positioning guide plates 8 penetrate, so that when the driving screw 3 rotates, the positioning guide plates 8 connected to the lower ends of the lifting sleeve 5 are subjected to blocking action of the two guide rods 9, and the driving screw 3 does not rotate along with the driving screw 3.
In addition, a pad 10 is further disposed on the top surface of the bearing seat 1 inside the door-shaped bracket 2, and the pad 10 is a hard plate body and is generally made of metal materials (such as steel, iron, etc.), and is horizontally attached to the top surface of the bearing seat 1 for increasing the supporting strength of the top surface of the bearing seat 1. As shown in fig. 4, a lower pressing block 12 which is matched with the upper pressing block 6 is connected to the backing plate 10 through a pressure sensor 11; at the same time, a sensor panel 13 should be further disposed on the side wall of the portal frame 2, and a signal input end of the sensor panel 13 is electrically connected to a signal output end of the pressure sensor 11, so that a pressure signal of the pressure sensor 11 can be received in real time and displayed on the sensor panel 13.

Further, since the two end faces of the air spring 7 are of the arc-shaped structures, an arc-shaped upper clamping groove 18 (shown in fig. 3) can be formed in the bottom face of the upper pressing block 6, and an arc-shaped lower clamping groove 19 (shown in fig. 4) corresponding to the arc-shaped upper clamping groove 18 in an adapting manner is formed in the top face of the lower pressing block 12, so that the air spring 7 needing to be subjected to pressure test can be firmly clamped between the upper pressing block 6 and the lower pressing block 12 through the arc-shaped upper clamping groove 18 and the arc-shaped lower clamping groove 19, and the air spring 7 can be more stably moved downwards by the upper pressing block 6. Of course, the arc-shaped upper clamping groove 18 and the arc-shaped lower clamping groove 19 are positioned on the axis of the lifting sleeve 5, so that the air spring 7 clamped between the arc-shaped upper clamping groove 18 and the arc-shaped lower clamping groove 19 can be applied with pressure along the axis direction when the lifting sleeve 5 moves downwards, the air spring 7 can be ensured to be stressed and compressed along the axis direction of the air spring 7, and the elasticity of the air spring 7 can be accurately measured; meanwhile, the pressure sensor 11 should be disposed at a position right below the arc-shaped lower clamping groove 19, so as to ensure that the pressure sensor 11 can accurately monitor the stress variation of the pressing block 12 (namely, the stress variation of the gas spring 7).
When the device is used, the transmission screw rod 3 is driven to rotate forward or reversely through the bidirectional motor 4 according to the length of the gas spring 7 to be tested, so that the height position of the upper pressing block 6 is adjusted, the gas spring 7 can be clamped between the upper pressing block 6 and the lower pressing block 12, and the gas spring 7 is ensured to be positioned on the axis of the lifting sleeve 5; then driving an electric cylinder 16 in a mounting cavity 15 of the bearing seat 1 to move, pushing a horizontal supporting plate 17 downwards to prop the horizontal supporting plate 17 on the ground, and propping up the whole bearing seat 1 to lift up universal mute wheels 14 at four corners of the bottom surface of the bearing seat 1 off the ground, so that the horizontal supporting plate 17 is ensured to firmly prop up the whole bearing seat 1; then, the air spring 7 can be clamped between the upper pressing block 6 and the lower pressing block 12, and the bidirectional motor 4 is driven to rotate again to push the upper pressing block 6 downwards, so that the lower air spring 7 performs pressure test. After the test is completed, the bidirectional motor 4 is driven reversely, so that the upper pressing block 6 moves upwards, and the air spring 7 is taken out.
