[0026] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0027] like Figure 1-7 The shock absorbing fixture shown in the figure includes a driver 2, which is used to drive the entire fixture to achieve clamping and releasing actions. The movable end of the driver 2 is connected to a telescopic component 3, which is used to transfer the action direction of the driver 2 to a vertical direction. The specific structure of the telescopic component 3 includes an inclined upper connecting rod 301 and a lower connecting rod 302. The upper connecting rod 301 is equal in length and parallel to the lower connecting rod 302. The upper end of the upper connecting rod 301 is also hinged with an upper turning handle 303. The upper end of the lower connecting rod 302 is The lower end of the lower connecting rod 302 is hinged to the middle part of the upper rotating handle 304, and the lower end of the upper connecting rod 301 is hinged to the middle part of the lower rotating handle 304. The upper connecting rod 301 and the upper rotating handle 303 are hinged to a lower swing arm 306. The lower end of the lower swing arm 306 and the upper end of the lower rotating handle 304 are jointly rotatably connected to a clamping plate 4. The axis of the rotational connection between the lower swing arm 306 and the clamping plate 4 is parallel to the axis of the rotational connection between the lower rotating handle 304 and the clamping plate 4. The lower end of the lower handle 304 of the lower connecting rod 302 is hinged with an upper swing arm 305, and the upper end of the upper swing arm 305 and the lower end of the upper handle 303 are rotatably connected to another clamping plate 4. Similarly, the axis of the rotational connection between the upper swing arm 305 and the other clamping plate 4 is parallel to the axis of the rotational connection between the upper handle 303 and the clamping plate 4, but not in the same line. Usually, the length of the upper handle 303, the lower handle 304, the upper swing arm 305 and the lower swing arm 306 is The length of the upper connecting rod 301 is half of the length of the upper turning handle 303, the length of the lower connecting rod 302 is half of the length of the lower turning handle 304, the lower end of the upper connecting rod 301 is hinged in the middle of the lower turning handle 304, and the upper end of the lower connecting rod 302 is hinged in the middle of the upper turning handle 303. Therefore, the middle area surrounded by the upper connecting rod 301, the lower connecting rod 302, the upper turning handle 303 and the lower turning handle 304 is a rhombus, and the upper and lower end points of the rhombus can be maintained in the same vertical direction.

[0028] Each clamping plate 4 includes a pair of limiting plates 401. Normally, at least the opposite sides of the limiting plates 401 are parallel to each other to achieve a uniform limiting effect. The two limiting plates 401 are fixedly connected to a force plate 402 on one side facing away from the telescopic component 3. The force plate 402 is the part that directly contacts the inner wall of the shock absorber. Because the shock absorber is mostly a rotating body, the side of the force plate 402 facing away from the telescopic component 3 is a convex cylindrical surface, which can better fit the inner wall of the shock absorber. An upper rotating shaft 403 and a lower rotating shaft 404 with parallel axes are also provided between the two limiting plates 401. The two rotating shafts can usually be directly fixed to the limiting plates 401. The upper rotating shaft 403 is close to the upper end of the force plate 402 and is used for contacting with the lower handle 304 or the upper swing arm 305. The upper end is rotatably connected, and the lower rotating shaft 404 is close to the lower end of the force plate 402, which is used to be rotatably connected with the lower end of the lower handle 304 or the lower swing arm 306, so that the two clamping plates 4 can remain parallel in the vertical direction. The upper end of the force plate 402 has a clamping plate 405 and the lower end has a supporting plate 406, both of which can contact the end face of the shock absorber sleeved outside the force plate 402, and the supporting plate 406 can provide a pre-positioning effect when the shock absorber is placed, and the clamping plate 405 can suppress the clamped shock absorber from moving upward when subjected to force. The distance that the supporting plate 406 exceeds the cylindrical surface of the force plate 402 is greater than the distance that the clamping plate 405 exceeds the cylindrical surface of the force plate 402, ensuring that the clamping plate 405 can pass through the shock absorber and be held by the supporting plate 406.

[0029] The upper end of the upper connecting rod 301 and the lower end of the lower connecting rod 302 are driven independently by the driver 2. Specifically, the driver 2 includes an upper tractor 210 and a lower tractor 220. The upper tractor 210 and the lower tractor 220 both use cylinders. The lower ends of the upper tractor 210 and the lower tractor 220 are commonly connected to a base 1. The base 1 is fixedly arranged, for example, fixedly connected to a frame. The upper tractor 210 includes a first cylinder 21 fixedly connected to the base 1. 1, a front telescopic rod 212 is movably connected in the first cylinder 211 to form a cylinder structure, and an upper linkage shaft 213 is fixedly connected to the upper end of the front telescopic rod 212 to form a rotation pair with the upper connecting rod 301, the upper rotating handle 303 and the upper end of the lower swing arm 306. The end of the upper linkage shaft 213 passes through the lower swing arm 306, the upper rotating handle 303 and the upper connecting rod 301 and is fixedly connected to a rear limiting ring 214 to ensure that the lower swing arm 306, the upper rotating handle 303 and the upper connecting rod 301 are in a state of rotation. The connecting rod 301 is plugged into the upper linkage shaft 213 to ensure the stability of the connection. The lower tractor 220 includes a second cylinder 221 fixedly connected to the base 1. The second cylinder 221 is movably connected with a rear telescopic rod 222 to form another cylinder structure. The upper end of the rear telescopic rod 222 is fixedly connected with a lower linkage shaft 223 to form a rotation pair with the lower connecting rod 302, the lower rotating handle 304 and the lower end of the upper swing arm 305. The end of the lower linkage shaft 223 passes through the lower rotating handle 304. 4 and the outer side surface behind the lower connecting rod 302 is provided with a front limiting ring 224, which is also used to ensure the plugging stability of the lower turning handle 304 and the lower connecting rod 302 and the lower linkage shaft 223. Since each component has a certain thickness and the upper turning handle 303 is located between the lower connecting rod 302 and the upper swing arm 305, the front limiting ring 224 also needs to be located between the upper swing arm 305 and the lower connecting rod 302 to ensure the stability of the spacing between the upper swing arm 305 and the lower connecting rod 302.

[0030] Working principle: In the initial state, the two splints 4 are in the closest position, and the distance between the farthest ends of the two clamping plates 405 is smaller than the inner diameter of the shock absorber, and can pass through the center hole of the shock absorber until the lower end of the shock absorber contacts the support plate 406. At this time, the shock absorber will be sleeved outside the two force plates 402, and then the driver 2 is started to make the upper linkage shaft 213 and the lower linkage shaft 223 move away from each other, and the telescopic assembly 3 will stretch in the horizontal direction to make the two splints 4 move away from each other until they contact the inner wall of the center hole of the shock absorber and apply an outward expansion force to clamp the shock absorber. When the shock absorber is assembled or tested, the telescopic assembly 3 is retracted again. Since the upper linkage shaft 213 and the lower linkage shaft 223 can move up or down synchronously, the splint 4 can be automatically separated from the shock absorber.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
