DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 3 As shown, the utility model provides a vehicle shock absorber processing quality detection device, including a mounting frame 1, a pressure hydraulic cylinder 2 is installed on the top of the mounting frame 1, the telescopic end of the pressure hydraulic cylinder 2 is fixedly connected to a top frame 3, the inner wall of the top frame 3 is fixedly connected to a sleeve rod 4, and two sleeve plates 5 are sleeved on the sleeve rod 4, so that the two sleeve plates 5 can slide left and right on the two sleeve rods 4, the surfaces of the two sleeve plates 5 are sleeved with sleeve frames 6, and the bottom ends of the sleeve frames 6 are slidably connected to the mounting frame 1, so that the bottom ends of the sleeve frames 6 can only slide horizontally on the mounting frame 1, so that the sleeve plates 5 can slide up and down in the sleeve frames 6, and at the same time, the sleeve frames 6 will also drive the sleeve plates 5 to move together when moving horizontally, and two relative cylinders 7 are installed on the front side of the mounting frame 1, and the telescopic ends of the two cylinders 7 are respectively connected to the two sleeve frames 6, and the synchronous operation of the two cylinders 7 can make the two sleeve frames 6 approach each other, and drive the two sleeve plates 5 to approach together, and the adjacent side surfaces of the two sleeve frames 6 are fixedly connected to the first positioning column 10, and the adjacent side surfaces of the two sleeve plates 5 are fixedly connected to the There is a second positioning column 9. Through the setting of the above structure, when the shock absorber is positioned and fixed, it is only necessary to place the shock absorber between the two sleeve frames 6 so that the connecting heads at both ends of the shock absorber are aligned with the two first positioning columns 10 and the two second positioning columns 9 respectively. Then, the two cylinders 7 are controlled to operate synchronously to make the two sleeve frames 6 and the two sleeve plates 5 close to each other. Then, the two second positioning columns 9 and the two first positioning columns 10 are respectively inserted into the connecting heads at both ends of the shock absorber to complete the fixation of the shock absorber at both ends. There is no need for personnel to fix the two ends of the shock absorber separately. Finally, the pressure-applying hydraulic cylinder 2 is controlled to drive the top frame 3 to rise and fall, so that the lifting of the top frame 3 simultaneously drives the two sleeve plates 5 to slide in the two sleeve frames 6, thereby performing a tensile test on the shock absorber for the compression resistance and rate quality test of the shock absorber, and observing whether the shock absorber has abnormal noise, oil leakage, etc. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, a positioning seat 8 is fixedly connected to the front of the mounting frame 1, and two relative positioning plates 14 are elastically provided on the front of the positioning seat 8. A support seat 11 is fixedly connected to the lower part of the front of the positioning seat 8. The shock absorber can be quickly positioned by the positioning plate 14, which is beneficial to the subsequent fixation of the shock absorber. Through the setting of the support seat 11, the bottom of the shock absorber can be supported, so that the bottom end of the shock absorber can be positioned and fixed by the two first positioning columns 10.

[0021] like Figure 3 As shown, two mounting grooves 15 are provided on the front of the positioning seat 8, and the rear ends of the two positioning plates 14 are respectively hinged in the two mounting grooves 15, and a plurality of compression springs 16 are fixedly connected to the surfaces of the two positioning plates 14, and the other ends of the two groups of compression springs 16 are respectively fixedly connected to the inner side walls of the two mounting grooves 15. Through the arrangement of the above structure, the two positioning plates 14 can play a preliminary positioning effect on the shock absorber, without the need for personnel to continuously hold the shock absorber, and the two positioning plates 14 can be suitable for shock absorbers of different diameters, and when positioning the shock absorber, it only needs to be pushed directly between the two positioning plates 14. Since the front ends of the two positioning plates 14 are open outward, it is convenient for personnel to directly place the shock absorber, and after the shock absorber is detected, the second positioning column 9 and the first positioning column 10 are moved away from the shock absorber, and then the shock absorber is pulled outward.

[0022] like Figure 1 and Figure 2 As shown, two guide grooves 12 are provided on the mounting frame 1, and the inner wall of each guide groove 12 is fixedly connected with a guide rod 13, and the bottom ends of the two sleeve frames 6 are respectively sleeved on the two guide rods 13. Through the setting of the guide rods 13 and the guide grooves 12, the sleeve frames 6 can slide stably on the mounting frame 1, which has a limiting effect on the sleeve frames 6.

[0023] like Figure 1 and Figure 2 As shown, the second positioning column 9 and the first positioning column 10 are both semi-cylindrical, and the two second positioning columns 9 and the two first positioning columns 10 are staggered, and the two sleeve plates 5 and the two sleeve frames 6 are close to each other, so that the two second positioning columns 9 and the two first positioning columns 10 can be inserted into the connecting rings at both ends of the shock absorber for positioning, thereby ensuring the stability of the shock absorber after positioning, and there is no need for personnel to fix the two ends of the shock absorber separately.

[0024] like Figure 1 and Figure 2 As shown, the surfaces of the two sleeve plates 5 are inlaid with balls arranged at equal distances, and the sleeve plates 5 are slidably arranged in the sleeve frame 6 through the balls. The setting of the balls makes the sleeve plates 5 slide more smoothly in the sleeve frame 6, and reduces the sliding friction of the sleeve plates 5 in the sleeve frame 6, thereby ensuring the sliding stability of the sleeve plates 5 and reducing the degree of wear between the sleeve plates 5 and the sleeve frame 6.

[0025] The working principle and use process of the utility model: when the shock absorber is subjected to quality tensile testing, it is directly pushed between the two positioning plates 14 for positioning, and the bottom end of the shock absorber is also supported by the support seat 11 to effectively prevent it from tipping over, without the need for personnel to continuously hold it, and then the connecting heads at both ends of the shock absorber are respectively aligned with the two first positioning columns 10 and the two second positioning columns 9, and then the two cylinders 7 are controlled to operate synchronously to make the two sleeve frames 6 and the two sleeve plates 5 close to each other, so that the two second positioning columns 9 and the two first positioning columns 10 are respectively inserted into the connecting heads at both ends of the shock absorber, and the shock absorber can be quickly fixed at both ends. , there is no need for personnel to fix the two ends of the shock absorber separately, and finally control the pressure hydraulic cylinder 2 to drive the top frame 3 to rise and fall, so that the lifting of the top frame 3 simultaneously drives the two sleeve plates 5 to slide in the two sleeve frames 6, thereby performing a tensile test on the shock absorber for the compression resistance and rate quality test of the shock absorber. When the shock absorber completes the test, it is only necessary to use the operation of the two cylinders 7 to control the two sleeve plates 5 and the two sleeve frames 6 to move away from each other, and at the same time drive the two second positioning columns 9 and the two first positioning columns 10 to move away from each other, thereby releasing the positioning of the two ends of the shock absorber, without the need for other operations by personnel, and finally directly remove the shock absorber from the front of the positioning seat 8.
