[0033] The following is a detailed description through specific embodiments.

[0034] like Figures 1 to 3 As shown, an embodiment of the utility model provides an assembly mechanism of a shock absorber, which is used for compressing a spring when assembling the shock absorber, and includes a base 100, a fixing assembly 200, a clamping assembly 300 and a guide assembly 400. The fixing assembly 200 is fixedly connected to the base 100 and is used to fix the spring of the shock absorber; the guide assembly 400 includes a guide column 410, which is mounted thereon perpendicular to the base 100, and the clamping assembly 300 is slidably connected to the guide column 410 and slides along the axial direction of the guide column 410.

[0035] In this embodiment, the fixing assembly 200 includes a fixing member 210, and a fixing through hole 211 is opened on the fixing member 210. The opening direction of the fixing through hole 211 is perpendicular to the base 100, and is used to accommodate the spring of the shock absorber. The diameter of the fixing through hole 211 is set to be slightly larger than or equal to the diameter of the spring to prevent the spring from moving. The height of the fixing member 210 needs to be set higher to play the role of fixing the piston rod and the lower part of the spring, and the inner wall of the fixing through hole 211 is used to limit the spring and the piston rod to prevent radial displacement.

[0036] In this embodiment, a through slot 212 is further provided on the fixing member 210, one end of the through slot 212 is connected to the fixing through hole 211, and the other end penetrates the side wall of the fixing member 210. The through slot 212 is designed to facilitate the piston rod to enter the fixing through hole 211 from the side. If there is no through slot 212, the piston rod needs to be inserted into the fixing through hole 211 from top to bottom, which requires a relatively high height of the assembly mechanism.

[0037] In this embodiment, the width of the through slot 212 is smaller than the width of the fixing through hole 211. Specifically, the fixing through hole 211 is a circular hole with a diameter of 12.5 cm, the through slot 212 intersects with the fixing through hole 211, and the fixing member 210 is divided into two parts by the through slot 212 and the fixing through hole 211. The overall outer shape of the fixing member 210 is a quadrangular prism with a square bottom surface, the side length of the square is 20.5 cm, the height of the quadrangular prism is 14 cm, and the width of the through slot 212 is 7 cm.

[0038] In this embodiment, the fixing assembly 200 further includes a fixing member mounting seat 220, which is fixed on the base 100, and the fixing member 210 is detachably connected to the fixing member mounting seat 220. The fixing member mounting seat 220 is a frame, which is mounted on the fixing member 210 and wraps the outer side of the fixing member 210 to fix the fixing member 210. The fixing member mounting seat 220 plays a role in strengthening the anti-displacement ability of the fixing member 210. The fixing member mounting seat 220 is provided with a horizontal bar on the through groove 212 for connecting the two parts of the fixing member 210. When the spring is compressed, it may collide with the fixing member 210 on one side, and the horizontal bar can strengthen the anti-collision ability of the fixing member 210.

[0039] In the present embodiment, the clamping assembly 300 includes at least one clamping mechanism 310, and the clamping mechanism 310 includes a guide 311, a clamping arm 312 and an extrusion member 313. One end of the guide 311 is fixedly connected to the clamping arm 312, and the other end is slidably connected to the guide column 410. The extrusion member 313 is fixedly connected to one end of the clamping arm 312 toward the fixed assembly 200, and a limited slot is provided on the extrusion member 313. Specifically, two clamping mechanisms 310 are provided in the embodiment of the utility model, wherein the clamping arm 312 of one clamping mechanism 310 is a long arm with a length of 50 cm; the clamping arm 312 of the other clamping mechanism 310 is a short arm with a length of 45 cm. The extrusion member 313 is an elastic pad, and the overall height of the extrusion member 313 is 6.2 cm, and a groove is provided at the bottom of the extrusion member 313. The depth of the bottom groove of the extrusion member 313 connected to the long arm is 4 cm, and the bottom groove of the other extrusion member 313 connected to the broken arm is 3 cm. The cantilever of the shock absorber is usually curved and generally horizontal. When the shock absorber is assembled, the extrusion piece 313 of the broken arm presses the higher part of the cantilever downward, and the extrusion piece 313 of the long arm presses the lower part of the cantilever downward. The clamping arm 312 is a pneumatic arm, and the clamping mechanism 310 is also provided with a pressure gauge inspection device for detecting whether the air pressure of the clamping arm 312 is in the correct working state, so as to control the force and distance of pressing the cantilever.

[0040] Specifically, an installation space is formed between the two clamping arms 312. When the extrusion piece 313 moves downward to extrude the cantilever, the upper end of the piston rod enters the installation space. When the cantilever moves to a preset position, the cantilever is fixedly connected to the piston rod, and the fixed connection point between the cantilever and the piston rod is located in the installation space.

[0041] In the present embodiment, two mounting holes 3111 are provided on the guide member 311, and the mounting holes 3111 are respectively arranged at the two ends of the guide member 311. The clamping arm 312 passes through one of the mounting holes 3111 and is fixedly connected to the guide member 311, and the other mounting hole 3111 is used to be sleeved on the guide post 410. Specifically, the guide member 311 moves up and down with the clamping arm 312, and the other mounting hole 3111 plays a role in guiding the moving direction of the clamping arm 312 when it moves up and down on the guide post 410. The moving direction of the clamping arm 312 is consistent with the axial direction of the guide post 410. In the embodiment of the utility model, two guide posts 410, two clamping arms 312 and four guide members 311 are provided, and two guide rings are allocated to each guide post 410 and the clamping arm 312 to limit the moving directions of the two clamping arms 312 to be consistent.

[0042] In this embodiment, the clamping assembly 300 further includes a transmission mechanism 500, which includes a transmission member 510 and a crossbeam 520. The two sides of the crossbeam 520 are respectively fixedly connected to the clamping mechanism 310 and the transmission member 510, and are used to transmit the force carried by the transmission member 510 to the clamping mechanism 310. One end of the transmission member 510 is connected to a device that provides pressure, such as a cylinder or hydraulic equipment, and the other end is fixedly connected to the crossbeam 520, and is used to transmit the pressure received downward to the crossbeam 520. The length of the crossbeam 520 is 36 cm. The two clamping arms 312 in the embodiment of the utility model are respectively fixedly connected to the two ends of the crossbeam 520 to ensure that they move up and down with the crossbeam 520 at the same time.

[0043] In this embodiment, the transmission mechanism 500 further includes a limiter 530, which is fixedly connected to the base 100, and has a limit hole 531 formed thereon, through which the transmission member 510 passes and slides, for limiting the moving direction of the transmission member 510 to up and down movement.

[0044] In this embodiment, the guide assembly 400 further includes a support column 420, which is disposed on the side of the guide column 410. The support column 420 includes a vertical column and a horizontal column which are perpendicular to each other and connected to each other at the ends. The vertical column is fixedly connected to the base 100, and the horizontal column is fixedly connected to the side of the guide column 410, so as to increase the structural strength of the guide column 410.

[0045] The working principle of this embodiment is described below: Figures 1 to 3 As shown, a device providing pressure, such as a cylinder or hydraulic equipment, is located above the assembly mechanism of the shock absorber to provide driving force. The clamping arms 312 are located on both sides to guide the extrusion pieces 313 to press the cantilever downward. The arched groove at the bottom of the extrusion piece 313 is convenient for fixing the cantilever to prevent the cantilever from shaking. The design of the extrusion pieces 313 distributed on both sides prevents the cantilever from swinging left and right when pressed. The fixing through hole 211 is located at the bottom to fix the spring to prevent the position of the spring from changing when the spring is compressed. A barometer inspection device is used to detect whether the air pressure of the clamping arm 312 is in the correct working state.

[0046] The assembly mechanism of the shock absorber is used as follows: first, the spring is passed through the piston rod, and the piston rod is moved to the fixed through hole 211 through the through slot 212, and then the spring is placed in the fixed through hole 211 to fix the position of the piston rod and the spring. Then, the cantilever is installed on the piston rod, and the extrusion pieces 313 on both sides are driven by gas to contact the two ends of the cantilever and press down to a preset position, leaving a space in the middle. After the upper end of the piston rod passes through the center hole of the cantilever, the cantilever is fixed with an electric gun and a nut. After the extrusion piece 313 rises, the assembled shock absorber can be removed, and an assembly operation is completed.

[0047] It improves the efficiency and quality of employees' assembly of shock absorbers, and reduces their labor intensity and safety hazards. Excess materials at the production site are used for splicing to make a fixing 210 that matches the spring. A cylinder or hydraulic equipment is installed at the upper end of the assembly mechanism to provide driving force. Gas is used as the driving energy source, which is clean and efficient. Compared with the traditional method of pressing the cantilever with one hand and tightening the nut with the other hand, employees using the assembly mechanism can use both hands to tighten the nut, and no auxiliary personnel are required to complete the assembly. The air pressure of the clamping arm 312 is detected by the barometer inspection equipment, and the nut tightening operation is performed on the basis of ensuring effective clamping.

[0048] In summary, the embodiment of the utility model can first fix the piston rod and the spring in position through the fixing assembly 200, then guide the pressing assembly 300 to squeeze the cantilever to a preset position through the guide assembly 400, and finally fix the piston rod and the cantilever to complete the assembly. The pressing assembly 300 can be driven by a cylinder, changing the traditional manual pressing method to machine-driven pressing, and the efficiency of employees assembling the shock absorber is improved; the fixing assembly 200 prevents the spring from popping out, avoids safety accidents caused by exhaustion during manual pressing, reduces the safety hazards of misoperation, and improves the safety factor of the operator.

[0049] Furthermore, the fixing assembly 200 includes a fixing member 210 and a fixing member mounting seat 220. The fixing member 210 and the fixing member mounting seat 220 are detachably connected, and the corresponding fixing member 210 can be replaced according to different diameters of the piston rod and the spring.

[0050] The fixing member 210 is provided with a fixing through hole 211 and a through slot 212, which are used for the piston rod to move into the fixing through hole 211 through the through slot 212 after the spring is sleeved on the piston rod, and the spring slides down into the fixing through hole 211 and is fixed.

[0051] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
