Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber processing equipment, in particular to a shock absorber spring pressure testing device. Background Art

[0002] Automobile shock absorbers are used to slow down the conversion of spring elastic potential energy into kinetic energy during the shock absorption process, thereby preventing subsequent continuous vibration after the spring buffering and preventing excessive shaking of the vehicle body. The detection of the degree of expansion and contraction of the shock absorber is particularly important and is an important indicator for detecting its strength.

[0003] In the prior art, a telescopic device is used for testing, that is, the shock absorber is tested at different degrees of telescopic expansion to detect whether it can withstand the degree of change in expansion and contraction. Positioning components are mainly set at both ends of the shock absorber spring to fix the spring, and then the spring is compressed through the telescopic device. Since the spring is long, it is easy to bend during the compression process. The bent spring pops out of the positioning component, resulting in low detection efficiency and low safety efficiency.

[0021] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0022] Please refer to Figure 1-Figure 3 The present embodiment discloses a shock absorber spring pressure testing device, comprising a base plate 1 and a first vertical plate 2 and a second vertical plate 3 spaced apart at the top of the base plate 1, a pressure tester 4 being provided on the side of the first vertical plate 2 opposite to the second vertical plate 3, two linear guide rods 5 being provided between the first vertical plate 2 and the second vertical plate 3, two spring positioning assemblies 6 being symmetrically provided on the two linear guide rods 5, the two spring positioning assemblies 6 being able to move relative to or toward each other on the linear guide rods 5, a telescopic assembly 7 being detachably connected between the two spring positioning assemblies 6, the spring being sleeved on the outside of the telescopic assembly 7, a linear pushing assembly 8 being further provided on the top of the base plate 1, the transmission end of the linear pushing assembly 8 passing through the second vertical plate 3 and being transmission-connected to the spring positioning assembly 6 near the second vertical plate 3.

[0023] During specific use, the telescopic assembly 7 can be removed first, and then the spring can be placed on the outside of the telescopic assembly 7. The telescopic assembly 7 can then be installed between the two spring positioning assemblies 6. The spring positioning assembly 6 close to the first vertical plate 2 can be pushed so that the two spring positioning assemblies 6 clamp the spring. Then, the linear push assembly 8 can be started. The linear push assembly 8 pushes the two spring positioning assemblies 6 and the telescopic assembly 7 with the spring toward the pressure tester 4, thereby performing a pressure test on the spring. During the test, the linear push assembly 8 can prevent the spring from bending, thereby avoiding the spring from popping out, and improving the safety during the test. In addition, a scale is set along the length of the outer side of the linear guide rod 5, so that the compression of the spring can be measured during the test.

[0024] In this embodiment, please refer to Figure 3 The spring positioning assembly 6 includes a positioning plate 61 and two connecting ears 62 disposed on either side of the positioning plate 61. A fixing portion 611 is provided on the side of the positioning plate 61 near the telescopic assembly 7, which mates with the end of the telescopic assembly 7. The two connecting ears 62 are provided with guide holes that mate with the two linear guide rods 5. Specifically, the positioning portion 611 is a threaded hole or a slot, and the end of the telescopic assembly 7 is provided with a threaded rod or a clip that mates with the threaded hole or slot. This simplifies installation, reduces installation time, and saves time and cost.

[0025] Please refer to Figure 2A spring positioning groove 612 is provided on one side of the positioning plate 61 close to the telescopic component 7, thereby improving the stability of the spring and reducing the risk of the spring being out of position during compression, thereby improving the accuracy of the measurement.

[0026] In this embodiment, the telescopic assembly 7 includes a sleeve 71 and a guide rod 72 with one end sleeved within the sleeve 71. The guide rod 72 is provided with a limit ring 73 at one end located within the sleeve 71. The limit ring 73 can rotate and move linearly within the sleeve 71. The end of the sleeve 71 away from the guide rod 72 and the end of the guide rod 72 away from the sleeve 71 are respectively connected to two spring positioning assemblies 6. In this way, during the spring extension and contraction process, the sleeve 71 and the guide rod 72 move relative to each other and contract.

[0027] In this embodiment, the linear actuator assembly 8 includes a mounting base 81 disposed on the base plate 1 and a linear drive unit 82 disposed on the mounting base 81. The output end of the linear drive unit 82 passes through the second vertical plate 3 and is in driving connection with the spring positioning assembly 6 adjacent to the second vertical plate 3. Specifically, the linear drive unit 82 is a ball screw drive pair, a pneumatic cylinder, an oil cylinder, or an electric push rod.

[0028] Preferably, a first reinforcing rib 811 is provided on a side of the mounting seat 81 away from the linear driving portion 82 , which increases the strength of the mounting seat 81 and prevents the mounting seat 81 from shifting during the compression process, thereby improving the accuracy of the detection.

[0029] In this embodiment, a second reinforcing rib 21 is provided on the side of the first vertical plate 2 away from the pressure tester 4, thereby improving the stability of the first vertical plate 2 and preventing the first vertical plate 2 from shifting during the compression process, thereby improving the accuracy of the detection.

[0030] To sum up, in this embodiment, a telescopic component 7 is arranged between the two spring positioning components 6. Since the spring is arranged on the outside of the telescopic component 7, it can better prevent the spring from bending during compression and avoid the spring from popping out, thereby improving the safety of the device and further improving the detection efficiency.
