Description

Technical Field

[0001] This application relates to the technical field of shock absorber production equipment, and more specifically, to a shock absorber press-fitting device. Background Art

[0002] A shock absorber is a device used to suppress vibrations and plays an important role in the automotive suspension system. The main function of a shock absorber is to rapidly attenuate vehicle body vibrations, improving the ride comfort and smoothness of the vehicle. During vehicle operation, the shock absorber helps control the contact between the wheels and the ground, reducing the impact caused by uneven road surfaces, while maintaining good contact between the tires and the ground, enhancing the vehicle's handling stability.

[0003] The processing of shock absorbers requires placing shock absorber components such as bushings, oil seal washers, oil seals, and dust seals at the opening of the shock absorber body, and then press-fitting these components into the shock absorber body to achieve an interference fit. Existing processing equipment needs to take out the shock absorber body with the shock absorber components placed on it from the press-fitting station after the press-fitting is completed, place another shock absorber component, and then put it back into the press-fitting station for press-fitting again. Press-fitting multiple shock absorber accessories requires repeatedly moving the shock absorber and the time consumed for fixing the shock absorber in the press-fitting station each time is relatively long, resulting in a low assembly efficiency of the shock absorber. Summary of the Utility Model

[0004] The purpose of this application is to provide a shock absorber press-fitting device for the above problems, which can improve the assembly efficiency of the shock absorber and thus improve the above problems.

[0005] This application is achieved by the following technical solutions:

[0006] In some embodiments, this application provides a shock absorber press-fitting device, which includes a chassis, a press-fitting mechanism, and a positioning mechanism; the chassis has a first opening, the height direction of the chassis is the first direction, and the width direction of the chassis is the second direction; the press-fitting mechanism is arranged inside the chassis, and the press-fitting mechanism includes a first driving member and a press-fitting member; the positioning mechanism, arranged inside the chassis, includes a second driving member and a positioning seat, the positioning seat is used to fix the shock absorber, and the second driving member drives the positioning seat to rotate axially in the second direction to face the press-fitting member or face the first opening; wherein, the first opening faces the feeding position for installing shock absorber accessories on the shock absorber, the projection of the press-fitting member along the first direction falls on the positioning seat, and the first driving member drives the press-fitting member to move up and down along the first direction to press the shock absorber components placed on the shock absorber fixed on the positioning seat into the shock absorber for press-fitting.

[0007] In the technical solution of the embodiment of the present application, the pressing mechanism and the positioning mechanism are both arranged inside the chassis. The pressing mechanism includes a first driving member and a pressing member; the positioning mechanism includes a second driving member and a positioning seat for fixing the shock absorber. The second driving member drives the positioning seat to flip axially in the second direction to face the pressing member or face the first opening; the positioning mechanism has a pressing state and a loading state. When the positioning seat faces the pressing member, the positioning mechanism is in the pressing state. In the pressing state, the height direction of the positioning seat is parallel to the first direction, and the height direction of the shock absorber fixed on the positioning seat is also parallel to the first direction; when the positioning seat faces the first opening, the positioning mechanism is in the loading state. Wherein, the projection of the pressing member in the first direction falls on the positioning seat, and the first driving member drives the pressing member to move up and down in the first direction to press the shock absorber component placed on the shock absorber fixed on the positioning seat into the shock absorber for pressing; in the actual use process of the shock absorber pressing device provided by the present application, the positioning seat is in the loading state, the shock absorber is fixed upside down on the positioning seat, and then the shock absorber component is placed at the opening of the shock absorber. The second driving member drives the positioning seat to flip, and the positioning seat switches from the loading state to the pressing state. The positioning seat drives the shock absorber to flip so that the shock absorber faces the pressing member. The pressing member moves towards the shock absorber in the first direction under the drive of the first driving member. The pressing member contacts the shock absorber component, and then the pressing member continues to move until the shock absorber component is pressed into the shock absorber. The second driving member drives the pressing member to move away from the shock absorber in the first direction, and the pressing member disengages from the shock absorber. The pressing mechanism completes a pressing operation. Another shock absorber component is placed at the opening of the shock absorber manually or mechanically. The positioning mechanism and the pressing mechanism repeat the above steps until all the required shock absorber components are pressed into the shock absorber. The positioning seat is in the loading state, and the shock absorber is removed from the positioning seat for subsequent assembly operations. The shock absorber pressing device provided by the present application has only a short shock absorber flipping interval between multiple pressing operations, and only one shock absorber disassembly and assembly process, eliminating the process of repeatedly disassembling and assembling the shock absorber required in the existing assembly technology, simplifying the process flow, saving the time required for repeatedly disassembling and assembling the shock absorber, and accelerating the assembly efficiency of the shock absorber.

[0008] In some embodiments, the pressing member includes a first part and a second part. The surface of the first part facing away from the first driving member in the first direction is the first surface; the second part is connected to the first surface, and a first hole is provided on the surface of the second part facing away from the first part in the first direction. The first hole is for the shock absorber to extend into, and the bottom wall of the first hole is used to squeeze the shock absorber component placed in the shock absorber for pressing.

[0009] In the technical solution of the embodiment of the present application, during the pressing process, the shock absorber extends into the first hole, the bottom wall of the first hole squeezes the shock absorber component placed in the shock absorber, and the side wall of the first hole restricts the extension of the shock absorber component, so that the shock absorber component can contract into the opening of the shock absorber under extrusion.

[0010] In some embodiments, the number of the second parts is multiple, and the multiple second parts are arranged on the first surface along the second direction. From any one end to the other end of the sequentially arranged multiple second parts, the aperture of the first hole increases or decreases sequentially.

[0011] In the technical solution of the embodiment of the present application, from any one end to the other end of the sequentially arranged multiple second parts, the aperture of the first hole increases or decreases sequentially. Since the sizes and material extension degrees of different shock-absorbing components are different, a second part with a size adapted to the pressing requirement of a certain first hole among the multiple second parts can be selected according to the pressing requirements of different shock-absorbing components, improving the versatility of the pressed parts.

[0012] In some embodiments, the pressing mechanism further includes a movable assembly. The movable assembly is arranged between the first driving member and the pressed part. The movable assembly includes a slide rail, a slider and a third driving member. The slide rail extends along the second direction, the slide rail is slidably matched with the slider, and the slider is connected to the first part; the third driving member makes any one of the multiple first parts face the shock absorber by driving the slider to slide along the slide rail.

[0013] In the technical solution of the embodiment of the present application, the slide rail is slidably matched with the slider, and the slider is connected to the first part; the third driving member makes any one of the multiple first parts face the shock absorber by driving the slider to slide along the slide rail, so that the aperture of the first hole of the second part facing the shock absorber can meet the pressing requirements of the shock-absorbing accessories to be pressed on the shock absorber this time. By mechanically replacing the second part, on the one hand, the replacement speed of the second part is relatively fast and it faces the shock absorber, and on the other hand, the risk that workers' hands and other limbs are scratched or bruised by components such as the pressed parts when they reach into the chassis is reduced.

[0014] In some embodiments, the pressing mechanism further includes a transmission belt and a transmission assembly. The transmission assembly includes a pulley and a lead screw. The lead screw is rotatably arranged in the chassis, the lead screw extends along the first direction, the pulley is fixedly sleeved on the lead screw, and the pulley is connected to the output end of the first driving member through the transmission belt; the pressed part is provided with a threaded hole for meshing with the lead screw, and the lead screw passes through the threaded hole of the pressed part.

[0015] In the technical solution of the embodiment of the present application, the press-fitting mechanism further includes a transmission belt and a transmission assembly. The transmission assembly includes a pulley and a lead screw. The lead screw is rotatably arranged in the chassis, and the pulley is fixedly sleeved on the lead screw. The pulley is connected to the output end of the first driving member through the transmission belt. The transmission belt can stably drive the pulley to rotate while having a certain elasticity itself, which can mitigate impacts and vibrations, reduce noise, and provide smooth power output. In addition, in case of overload, the transmission belt will slip on the pulley, thus preventing other components from being damaged due to overload; the press-fitting member is provided with a threaded hole for meshing with the lead screw, and the lead screw passes through the threaded hole of the press-fitting member. The lead screw rotates synchronously with the pulley, and the rotation of the lead screw drives the press-fitting member to rise or fall along the lead screw. The transmission effect between the lead screw and the threaded hole is stable, the structure is relatively simple, which is convenient for installation and maintenance, and reduces the maintenance cost.

[0016] In some embodiments, the number of the transmission assemblies is multiple. The multiple transmission assemblies are divided into two groups and are respectively arranged on opposite sides of the press-fitting member along the second direction. The number of any one group of the transmission assemblies in the two groups is the same as that of the other group; the number of the threaded holes on the press-fitting member is multiple, and the multiple threaded holes correspond to the lead screws of the multiple transmission assemblies one by one.

[0017] In the technical solution of the embodiment of the present application, the multiple transmission assemblies are divided into two groups and are respectively arranged on opposite sides of the press-fitting member along the second direction. The multiple lead screws are meshed with the multiple threaded holes of the press-fitting member, restricting the axial rotation of the press-fitting member around any one lead screw. The number of any one group of the transmission assemblies in the two groups is the same as that of the other group, and the positions of the two groups of transmission assemblies correspond to each other one by one, so that the magnitudes of the forces that drive the press-fitting member to rise or fall from the lead screws at opposite ends of the press-fitting member along the second direction are similar or the same, reducing the risk of the press-fitting member tilting or flipping due to uneven force.

[0018] In some embodiments, a plurality of limiting shafts are further arranged inside the chassis. The limiting shafts extend along the first direction, and the limiting shafts are fixedly connected to the chassis; the press-fitting member is provided with a plurality of limiting holes for the limiting shafts to pass through. The plurality of limiting holes correspond to the plurality of limiting shafts one by one, and the hole walls of the limiting holes are in contact with the outer peripheral surfaces of the limiting shafts.

[0019] In the technical solution of the embodiment of the present application, a plurality of limiting shafts are further arranged inside the chassis. The limiting shafts extend along the first direction; the press-fitting member is provided with a plurality of limiting holes for the limiting shafts to pass through. The plurality of limiting holes correspond to the plurality of limiting shafts one by one, and the hole walls of the limiting holes are in contact with the outer peripheral surfaces of the limiting shafts. The cooperation between the limiting shafts and the limiting holes can limit the moving direction of the press-fitting member, reducing the risk of the press-fitting member deviating from the first direction during the moving process.

[0020] In some embodiments, the positioning mechanism also includes a shell, a gear and a rack. The shell is arranged on the bottom wall of the chassis, and the gear and the rack are meshed; the second driving member, the gear, the rack and the positioning seat are all arranged on the inner side of the shell. The top wall of the shell is provided with a second opening. The positioning seat is used to fix one end of the shock absorber through the second opening and extends out of the shell. The other end of the positioning seat is fixedly connected to the gear, and the gear is rotatably connected to the shell. The rack is connected to the output end of the second driving member, and the second driving member drives the rack to move to drive the gear to rotate axially in the second direction.

[0021] In the technical solution of the embodiment of the present application, the shell is arranged on the bottom wall of the chassis, and the gear and the rack are meshed; the second driving member, the gear, the rack and the positioning seat are all arranged on the inner side of the shell, and the shell can protect the working process of the second driving member, the gear, the rack and the positioning seat from being affected by the external environment. The top wall of the shell is provided with a second opening, and the positioning seat is used to fix one end of the shock absorber through the second opening and extend out of the shell, so that the shell will not block the connection or disassembly of the shock absorber and the positioning seat, and the other end of the positioning seat is fixedly connected to the gear, and the gear is rotatably connected to the shell, so that the position of the gear can always be kept facing the press-fitted part, and the rack is connected to the output end of the second driving member, and the second driving member drives the rack to move to drive the gear to rotate axially in the second direction. The transmission effect of the gear and the rack is stable, the structure is simple, and it is easy to install and maintain, which reduces the maintenance cost.

[0022] In some embodiments, the positioning mechanism further includes a first positioning member, the first positioning member is fixedly connected to the housing, and the first positioning member is in contact with a positioning seat facing the press-fitting member.

[0023] In the technical solution of the embodiment of the present application, the first positioning member is fixedly connected to the shell, and the first positioning member contacts the positioning seat facing the press-fitted part. When the positioning seat rotates to face the press-fitted part, the first positioning member contacts the positioning seat, restricting the positioning seat from continuing to rotate, so that the shock absorber fixed on the positioning seat can face the press-fitted part.

[0024] In some embodiments, a second positioning member is also provided on the inner side of the chassis, and the second positioning member is fixedly connected to the inner wall of the chassis facing the first opening. In the first direction, the second positioning member is located between the press-fit member and the positioning seat, and the second positioning member contacts the press-fit member of the press-fit shock absorber.

[0025] In the technical solution of the embodiment of the present application, a second positioning piece is also provided on the inner side of the chassis, and the second positioning piece is located between the press-fit piece and the positioning seat. When the press-fit piece presses the shock-absorbing component completely into the shock absorber, the second positioning piece contacts the press-fit piece, and the second positioning piece prevents the press-fitting machine from continuing to squeeze the shock absorber, thereby reducing the probability of damage to the shock absorber caused by excessive squeezing of the shock absorber by the press-fit piece.

[0043] According to some embodiments of the present application, optionally, as Figures 1 to 6 shown, the present application provides a shock absorber 1 press-fitting device. The shock absorber 1 press-fitting device includes a chassis 2, a press-fitting mechanism 3, and a positioning mechanism 4. The chassis 2 has a first opening 20. The height direction of the chassis 2 is the first direction X, and the width direction of the chassis 2 is the second direction Y. The press-fitting mechanism 3 is disposed inside the chassis 2. The press-fitting mechanism 3 includes a first driving member 30 and a press-fitting member 31. The positioning mechanism 4 is disposed inside the chassis 2. The positioning mechanism 4 includes a second driving member 40 and a positioning seat 41. The positioning seat 41 is used to fix the shock absorber 1. The second driving member 40 drives the positioning seat 41 to flip axially along the second direction Y to face the press-fitting member 31 or face the first opening 20. Wherein, the projection of the press-fitting member 31 along the first direction X falls on the positioning seat 41. The first driving member 30 drives the press-fitting member 31 to move up and down along the first direction X to press the shock absorber component placed on the shock absorber 1 fixed on the positioning seat 41 into the shock absorber 1 for press-fitting.

[0044] The chassis 2 is disposed on the ground or a working platform.

[0045] Taking the chassis 2 as an example, the bottom mentioned in this application is the part of the chassis 2 close to the ground or the working platform, and the top mentioned in this application is the part of the chassis 2 away from the ground or the working platform.

[0046] The X direction shown in the figure is the first direction.

[0047] The Y direction shown in the figure is the second direction.

[0048] The first opening 20 is disposed on the side wall of the chassis 2 parallel to the first direction X and the second direction Y.

[0049] The press-fitting mechanism 3 is disposed at the top inside the chassis 2, and the positioning mechanism 4 is disposed at the bottom inside the chassis 2.

[0050] Press-fitting is a process used in the machinery manufacturing industry for assembling cylindrical interference fit mating parts. The key to this technology is to apply a thrust greater than the press-fitting force to complete the assembly of parts.

[0051] The shock absorber 1 is in an inverted state when fixed to the positioning seat 41.

[0052] The positioning seat 41 can be a sleeve. The shock absorber 1 is inserted into the positioning seat 41, and the outer peripheral surface of the shock absorber 1 fits against the inner wall of the positioning seat 41. The structure is simple, the positioning seat 41 has a good fixing effect on the shock absorber 1, and the operation of plugging and unplugging for disassembly and assembly is relatively simple. Alternatively, the positioning seat 41 can be a plug shaft with a convex ring on the outside. The positioning seat 41 is inserted into the shock absorber 1 and supports the shock absorber 1 through the convex ring. The outer peripheral surface of the positioner fits against the inner wall of the shock absorber 1. The structure is simple, the positioning seat 41 has a good fixing effect on the shock absorber 1, and the operation of plugging and unplugging for disassembly and assembly is relatively simple.

[0053] The press-fitting mechanism 3 and the positioning mechanism 4 are both arranged inside the chassis 2. The press-fitting mechanism 3 includes a first driving member 30 and a press-fitting member 31; the positioning mechanism 4 includes a second driving member 40 and a positioning seat 41. The positioning seat 41 is used to fix the shock absorber 1, and the second driving member 40 drives the positioning seat 41 to flip axially along the second direction Y to face the press-fitting member 31 or face the first opening 20; the positioning mechanism 4 has a press-fitting state and a loading state. When the positioning seat 41 faces the press-fitting member 31, the positioning mechanism 4 is in the press-fitting state. In the press-fitting state, the height direction of the positioning seat 41 is parallel to the first direction X, and the height direction of the shock absorber 1 fixed on the positioning seat 41 is also parallel to the first direction X; when the positioning seat 41 faces the first opening 20, the positioning mechanism 4 is in the loading state. Among them, the projection of the press-fitting member 31 along the first direction X falls on the positioning seat 41, and the first driving member 30 drives the press-fitting member 31 to move up and down along the first direction X to press the shock-absorbing component placed on the shock absorber 1 fixed on the positioning seat 41 into the shock absorber 1 for press-fitting; in the actual use process of the shock absorber 1 press-fitting device provided by the present application, the positioning seat 41 is in the loading state, the shock absorber 1 is fixed upside down on the positioning seat 41, and then the shock-absorbing component is placed at the opening of the shock absorber 1. The second driving member 40 drives the positioning seat 41 to flip, and the positioning seat 41 switches from the loading state to the press-fitting state. The positioning seat 41 drives the shock absorber 1 to flip so that the shock absorber 1 faces the press-fitting member 31. The press-fitting member 31 moves along the first direction X towards the shock absorber 1 under the drive of the first driving member 30. The press-fitting member 31 contacts the shock-absorbing component, and then the press-fitting member 31 continues to move until the shock-absorbing component is pressed into the shock absorber 1. The second driving member 40 drives the press-fitting member 31 to move away from the shock absorber 1 along the first direction X, and the press-fitting member 31 disengages from the shock absorber 1. The press-fitting mechanism 3 completes a press-fitting operation. Another shock-absorbing component is placed at the opening of the shock absorber 1 manually or mechanically. The positioning mechanism 4 and the press-fitting mechanism 3 repeat the above steps until all the required shock-absorbing components are pressed into the shock absorber 1. The positioning seat 41 is in the loading state, and the shock absorber 1 is removed from the positioning seat 41 for subsequent assembly operations. The shock absorber 1 press-fitting device provided by the present application can press-fit different shock-absorbing accessories, and there is only a short flipping interval of the shock absorber 1 between multiple press-fitting operations, and there is only one disassembly and assembly process of the shock absorber 1, which omits the process of repeatedly disassembling and assembling the shock absorber 1 required in the existing assembly technology, simplifies the process flow, saves the time required for repeatedly disassembling and assembling the shock absorber 1, and improves the assembly efficiency of the shock absorber 1.

[0054] The angle between the axis of the positioning seat 41 in the loading state and the axis of the positioning seat 41 in the press-fitting state does not exceed 30°, so that when the positioning seat 41 is in the loading state, the shock-absorbing component placed on the shock absorber 1 is not easy to slide off.

[0055] According to some embodiments of the present application, optionally, such as Figures 1 to 7As shown, the press-fitting part 31 includes a first part 310 and a second part 311. The surface of the first part 310 facing away from the first driving part 30 in the first direction X is the first surface 3100. The second part 311 is connected to the first surface 3100. A first hole 3110 is provided on the surface of the second part 311 facing away from the first part 310 in the first direction X. The shock absorber 1 is configured to extend into the first hole 3110, and the bottom wall of the first hole 3110 is used to squeeze the shock-absorbing component placed on the shock absorber 1 for press-fitting.

[0056] The side wall of the first hole 3110 can be in contact with the outer peripheral surface of the shock-absorbing component. The side wall of the first hole 3110 can limit the displacement of the shock-absorbing component while pressing the shock-absorbing component towards the opening of the shock absorber 1, causing the shock-absorbing component to deform uniformly.

[0057] During the press-fitting process, the shock absorber 1 extends into the first hole 3110. The bottom wall of the first hole 3110 squeezes the shock-absorbing component placed on the shock absorber 1, and the side wall of the first hole 3110 restricts the extension of the shock-absorbing component, enabling the shock-absorbing component to contract into the opening of the shock absorber 1 under extrusion.

[0058] According to some embodiments of the present application, optionally, as Figures 1 to 7 shown, the number of the second parts 311 is multiple. The multiple second parts 311 are arranged on the first surface 3100 along the second direction Y. Starting from any one end to the other end of the sequentially arranged multiple second parts 311, the aperture of the first hole 3110 increases or decreases in sequence.

[0059] The number of the multiple second parts 311 can be three, four, five, six, seven, eight, nine, ten or more.

[0060] Starting from any one end to the other end of the sequentially arranged multiple second parts 311, the aperture of the first hole 3110 increases or decreases in sequence. Since the sizes and material extension degrees of different shock-absorbing components are different, a second part 311 with a first hole 3110 size adapted to the requirements can be selected from the multiple second parts 311 according to the press-fitting requirements of different shock-absorbing components, improving the versatility of the press-fitting part 31.

[0061] According to some embodiments of the present application, optionally, as Figures 3 to 6 shown, the press-fitting mechanism 3 further includes a movable component 32. The movable component 32 is arranged between the first driving part 30 and the press-fitting part 31. The movable component 32 includes a slide rail 320, a slider 321 and a third driving part 322. The slide rail 320 extends along the second direction Y. The slide rail 320 is slidably engaged with the slider 321. The slider 321 is connected to the first part 310. The third driving part 322 makes any one of the multiple first parts 310 face the shock absorber 1 by driving the slider 321 to slide along the slide rail 320.

[0062] The number of the sliding blocks 321 can be multiple. The multiple sliding blocks 321 are arranged along the second direction Y and are disposed on the first part 310. During the press-fitting process of the press-fitting part 31, the reaction force received by the first part 310 via the second part 311 can be applied to the slide rail 320 through the multiple sliding blocks 321, so that the force applied by a single sliding block 321 to the slide rail 320 is reduced, thereby reducing the risk that the slide rail 320 is locally deformed or damaged due to excessive pressure applied by a certain sliding block 321.

[0063] A position sensor can be arranged on the first surface 3100. The position sensor can timely measure the positions of the respective second parts 311. The third driving member 322 can timely adjust the positions of the sliding blocks 321 according to the measurement results of the position sensor, so that the first holes 3110 of the required second parts 311 can be directly opposite to the shock absorber 1.

[0064] The slide rail 320 is in sliding fit with the sliding block 321, and the sliding block 321 is connected to the first part 310; the third driving member 322 slides the sliding block 321 along the slide rail 320 to make any second part 311 in the multiple first parts 310 directly opposite to the shock absorber 1, so that the aperture of the first hole 3110 of the second part 311 directly opposite to the shock absorber 1 can meet the press-fitting requirements of the shock absorber fittings for this press-fitting on the shock absorber 1. By mechanically replacing the second part 311, on the one hand, the replacement speed of the second part 311 is relatively fast and it is directly opposite to the shock absorber 1, and on the other hand, the risk that a worker's hands and other limbs are scratched or bruised by components such as the press-fitting part 31 when reaching into the chassis 2 is reduced.

[0065] According to some embodiments of the present application, optionally, as Figures 2 to 4 shown, the press-fitting mechanism 3 further includes a transmission belt 33 and a transmission assembly 34. The transmission assembly 34 includes a pulley 340 and a lead screw 341. The lead screw 341 is rotatably arranged in the chassis 2. The lead screw 341 extends along the first direction X. The pulley 340 is fixedly sleeved on the lead screw 341. The pulley 340 is connected to the output end of the first driving member 30 through the transmission belt 33; the press-fitting part 31 is provided with a threaded hole for meshing with the lead screw 341, and the lead screw 341 passes through the threaded hole of the press-fitting part 31.

[0066] The pulley 340 can be arranged at the end of the lead screw 341, so that the length of the part of the lead screw 341 that can be in contact with the press-fitting part 31 is relatively long, the size of the movable path of the press-fitting part 31 in the first direction X is relatively long, and the press-fitting part 31 can press-fit a shock absorber 1 with a relatively long length.

[0067] The pressing mechanism 3 further includes a transmission belt 33 and a transmission assembly 34. The transmission assembly 34 includes a pulley 340 and a lead screw 341. The lead screw 341 is rotatably arranged in the chassis 2. The pulley 340 is fixedly sleeved on the lead screw 341. The pulley 340 is connected to the output end of the first driving member 30 through the transmission belt 33. The transmission belt 33 can stably drive the pulley 340 to rotate and has a certain elasticity itself, which can relieve shock and vibration, reduce noise, and provide stable power output. In addition, in case of overload, the transmission belt 33 will slip on the pulley 340, thus preventing other components from being damaged due to overload. The pressing member 31 is provided with a threaded hole for meshing with the lead screw 341. The lead screw 341 passes through the threaded hole of the pressing member 31. The lead screw 341 rotates synchronously with the pulley 340. The rotation of the lead screw 341 drives the pressing member 31 to rise or fall along the lead screw 341. The transmission effect between the lead screw 341 and the threaded hole is stable, the structure is relatively simple, convenient for installation and maintenance, and the maintenance cost is reduced.

[0068] According to some embodiments of the present application, optionally, as Figures 2 to 6 shown, the number of the transmission assemblies 34 is multiple. The multiple transmission assemblies 34 are divided into two groups and are respectively arranged on two opposite sides of the pressing member 31 along the second direction Y. The number of any one of the two groups of transmission assemblies 34 is the same as that of the other group of transmission assemblies 34. The number of the threaded holes on the pressing member 31 is multiple, and the multiple threaded holes correspond to the lead screws 341 of the multiple transmission assemblies 34 one by one.

[0069] The number of the multiple transmission assemblies 34 can be two, four, six or more.

[0070] The multiple transmission assemblies 34 are divided into two groups and are respectively arranged on two opposite sides of the pressing member 31 along the second direction Y. The multiple lead screws 341 are meshed with the multiple threaded holes of the pressing member 31, restricting the axial rotation of the pressing member 31 around any one of the lead screws 341. The number of any one of the two groups of transmission assemblies 34 is the same as that of the other group of transmission assemblies 34, and the positions of the two groups of transmission assemblies 34 correspond one by one, so that the magnitudes of the forces driving the pressing member 31 to rise or fall from the lead screws 341 at the two opposite ends of the pressing member 31 along the second direction Y are similar or the same, reducing the risk of the pressing member 31 tilting or flipping due to uneven force.

[0071] According to some embodiments of the present application, optionally, as Figures 1 to 6 shown, a plurality of limiting shafts 21 are further arranged inside the chassis 2. The limiting shafts 21 extend along the first direction X, and the limiting shafts 21 are fixedly connected to the chassis 2. The pressing member 31 is provided with a plurality of limiting holes for the limiting shafts 21 to pass through. The plurality of limiting holes correspond to the plurality of limiting shafts 21 one by one, and the hole wall of the limiting hole is attached to the outer peripheral surface of the limiting shaft 21.

[0072] The number of the plurality of orientation axes 21 can be two, three, four, five, six, seven, eight, nine, ten or more.

[0073] The number of the plurality of orientation holes can be two, three, four, five, six, seven, eight, nine, ten or more.

[0074] A plurality of orientation axes 21 are further arranged inside the chassis 2, and the orientation axes 21 extend along the first direction X; the pressing member 31 is provided with a plurality of orientation holes for the orientation axes 21 to pass through, the plurality of orientation holes correspond to the plurality of orientation axes 21 one by one, the hole wall of the orientation hole fits the outer peripheral surface of the orientation axis 21, and the cooperation between the orientation axis 21 and the orientation hole can limit the moving direction of the pressing member 31 and reduce the risk that the pressing member 31 deviates from the first direction X during movement.

[0075] According to some embodiments of the present application, optionally, as Figures 1 to 2 、 Figure 4 and Figure 8 shown, the positioning mechanism 4 further includes a housing 42, a gear 43 and a rack 44. The housing 42 is arranged on the bottom wall of the chassis 2, and the gear 43 meshes with the rack 44; the second driving member 40, the gear 43, the rack 44 and the positioning seat 41 are all arranged inside the housing 42. A second opening 420 is formed in the top wall of the housing 42. The positioning seat 41 is used to fix one end of the shock absorber 1 to pass through the second opening 420 and extend out of the housing 42. The other end of the positioning seat 41 is fixedly connected to the gear 43. The gear 43 is rotatably connected to the housing 42. The rack 44 is connected to the output end of the second driving member 40. The second driving member 40 drives the rack 44 to move to drive the gear 43 to rotate axially in the second direction Y.

[0076] In the first direction X, there is a gap between the bottom edge of the first opening 20 and the bottom wall of the chassis 2, and the dimension of the housing 42 in the first direction X is not greater than the dimension of this gap.

[0077] The housing 42 is disposed on the bottom wall of the chassis 2, and the gear 43 meshes with the rack 44; the second driving member 40, the gear 43, the rack 44, and the positioning seat 41 are all disposed inside the housing 42. The housing 42 can protect the working process of the second driving member 40, the gear 43, the rack 44, and the positioning seat 41 from the influence of the external environment. A second opening 420 is formed in the top wall of the housing 42. The positioning seat 41 is used to fix one end of the shock absorber 1 to pass through the second opening 420 and extend out of the housing 42, so that the housing 42 does not block the connection or disassembly of the shock absorber 1 and the positioning seat 41. The other end of the positioning seat 41 is fixedly connected to the gear 43. The gear 43 is rotatably connected to the housing 42, so that the position of the gear 43 can always be directly opposite to the press-fitting member 31. The rack 44 is connected to the output end of the second driving member 40. The second driving member 40 drives the rack 44 to move to drive the gear 43 to rotate axially in the second direction Y. The cooperation and transmission effect between the gear 43 and the rack 44 is stable, the structure is simple, it is convenient for installation and maintenance, and the maintenance cost is reduced.

[0078] According to some embodiments of the present application, optionally, as Figure 4 and Figure 8 shown, the positioning mechanism 4 further includes a first positioning member 45. The first positioning member 45 is fixedly connected to the housing 42, and the first positioning member 45 contacts the positioning seat 41 facing the press-fitting member 31.

[0079] The surface of the first positioning member 45 in contact with the positioning seat 41 can be adapted to the outer peripheral surface of the positioning seat 41.

[0080] The first positioning member 45 is fixedly connected to the housing 42, and the first positioning member 45 contacts the positioning seat 41 facing the press-fitting member 31. When the positioning seat 41 rotates to face the press-fitting member 31, the first positioning member 45 contacts the positioning seat 41 to limit the positioning seat 41 from continuing to rotate, so that the shock absorber 1 fixed on the positioning seat 41 can face the press-fitting member 31.

[0081] According to some embodiments of the present application, optionally, as Figure 4 and Figure 8 shown, a second positioning member 22 is further disposed inside the chassis 2. The second positioning member 22 is fixedly connected to the inner wall of the chassis 2 facing the first opening 20. In the first direction X, the second positioning member 22 is located between the press-fitting member 31 and the positioning seat 41, and the second positioning member 22 contacts the press-fitting member 31 for pressing the shock absorber 1.

[0082] The number of the second positioning members 22 can be multiple. The multiple second positioning members 22 are arranged along the second direction Y. The multiple second positioning members 22 can provide multiple fulcrums for the press-fitting member 31 of the shock absorber 1. The extrusion force of the press-fitting member 31 can be evenly dispersed to the multiple second positioning members 22, reducing the risk of damage to the second positioning member 22 or local deformation and damage of the press-fitting member 31 caused by excessive extrusion force between the press-fitting member 31 and a single second positioning member 22.

[0083] A second positioning member 22 is further provided inside the chassis 2. The second positioning member 22 is located between the press-fitting member 31 and the positioning seat 41. When the press-fitting member 31 completely presses the shock-absorbing component into the shock absorber 1, the second positioning member 22 contacts the press-fitting member 31, and the second positioning member 22 blocks the press-fitting machine from continuing to squeeze the shock absorber 1, reducing the probability of damage to the shock absorber 1 caused by excessive squeezing of the shock absorber 1 by the press-fitting member 31.

[0084] Although the present application has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
