Description
Technical Field
[0001] This utility model relates to the technical field of fixed tooling for automobile shock absorber production, specifically to a tooling for shock absorber production. Background Technology
[0002] Automotive shock absorbers are the core components of automotive suspension systems. They are vibration damping devices whose main function is to attenuate vibrations caused by road impacts, thereby improving ride comfort and handling safety. Among them, electronically controlled shock absorbers are widely used in the automotive manufacturing industry because they can adjust the vehicle's suspension damping force in real time through an electronic control system, thereby improving dynamic balance, driving comfort, and handling stability.
[0003] The existing fixed tooling for the production of electronically controlled shock absorbers is mainly divided into three categories: single-specification fixed tooling, simple adjustable tooling, and automated accompanying tooling. However, single-specification fixed tooling is adapted to the specifications of the shock absorbers one by one and cannot be adjusted; simple adjustable tooling has a simple structure and a limited range of adaptability; while automated accompanying tooling is mostly custom-made and lacks flexibility.
[0004] Most of the fixed fixtures used in the production of the aforementioned electronically controlled shock absorbers are rigidly fixed and lack modular, flexible, and compatible integrated designs, resulting in poor versatility and causing many inconveniences to the production of electronically controlled shock absorbers. Utility Model Content
[0005] The purpose of this utility model is to provide a tooling for the production of shock absorbers, so as to solve the technical problem that most existing fixed tooling for the production of electronically controlled shock absorbers adopts rigid fixing, lacks modular, flexible and compatible integrated design, and has poor versatility.
[0006] This utility model proposes a tooling for the production of shock absorbers, including a reference component and a limiting component. The limiting component is detachably mounted on the reference component and is used to limit and fix the shock absorber.
[0007] The limiting component includes a top block, a guide arc surface, two sets of clamping arms, and an elastic element;
[0008] The top block is movably disposed at one end of the clamping arm to limit the clamping arm. Two sets of clamping arms are arranged opposite to each other. Each set of clamping arms can move around the fixed end. The guide arc surface is opened on the side wall where the top block contacts the clamping arm to assist the clamping arm in moving.
[0009] One end of each of the two sets of clamping arms is connected by the elastic element. When the shock absorber is placed between the two sets of clamping arms, the elastic element provides clamping force to the clamping arms.
[0010] Preferably, the limiting component further includes a fixing plate, which supports the top block and the clamping arm, and the fixing plate is provided with a guide rail that cooperates with the top block to guide and limit the top block.
[0011] Preferably, the limiting component further includes rollers, which are movably disposed at both ends of the clamping arm and protrude from the ends of the clamping arm.
[0012] Preferably, the elastic element is a spring.
[0013] Preferably, the reference component includes a base, a quick-release sleeve, and a support column base. The quick-release sleeve is disposed on the base and is used to install the support column base. One end of the support column base is detachably disposed inside the quick-release sleeve, and the other end is provided with a positioning groove that matches the shock absorber.
[0014] Preferably, the reference component further includes a guide frame, which is disposed on the base, and the limiting component is slidably sleeved on the guide frame.
[0015] Preferably, the reference assembly further includes a connecting rod and a top cover placement column. The connecting rod is detachably mounted on the guide frame to support the top cover placement column, and the top cover placement column is detachably mounted on the connecting rod.
[0016] Preferably, the reference assembly further includes a placement platform and a coil clamping fixture, which are respectively disposed on the base. The placement platform is used to temporarily store pre-installed valve components, and the coil clamping fixture is used to precisely press-fit the shock absorber electromagnetic coil.
[0017] Preferably, the reference component further includes a force detection unit, which is disposed on the base and electrically connected to the coil clamping fixture, for real-time acquisition and display of pressing force data.
[0018] Compared with the prior art, this utility model has at least the following advantages: In this utility model, the clamping cavity is formed by the cooperation of two sets of clamping arms to achieve radial clamping of the shock absorber cylinder. When the clamping arms clamp and fix the shock absorber cylinder, one end of the two sets of clamping arms compresses the elastic element, and the elastic element generates elastic force to act on the two sets of clamping arms, thereby providing continuous clamping force for the clamping arms. The clamping arms are elastically connected by the elastic element, which can flexibly fix the shock absorber. The guide arc surface can control different opening angles of the clamping arms, thereby facilitating the adaptation to shock absorber cylinders of different specifications. This achieves adaptive clamping for shock absorbers with different outer diameters, without the need for manual adjustment of the clamping amplitude, and has high versatility. Furthermore, the modular design of the limiting components also facilitates later maintenance and replacement. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The preferred embodiments described below are merely examples, and other obvious variations will be apparent to those skilled in the art. The basic principles of this invention as defined in the following description can be applied to other implementations, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this invention.
[0027] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.
[0028] As mentioned in the background art, this application proposes a tooling for shock absorber production, used to fix electronically controlled shock absorbers of different specifications during production line processing. Since electronically controlled shock absorbers need to be fixed in place during production line processing to facilitate transportation and processing, most existing fixed tooling for electronically controlled shock absorber production adopts rigid fixing, lacks modular, flexible and compatible integrated design, and has poor versatility, causing many inconveniences to the production of electronically controlled shock absorbers. Therefore, a tooling for shock absorber production is needed to fix electronically controlled shock absorbers of different specifications.
[0029] Specifically, please refer to, for example Figures 1 to 4 As shown in the figure, this embodiment proposes a tooling for the production of shock absorbers, including a reference component 1 and a limiting component 2. The limiting component 2 is detachably mounted on the reference component 1 and is used to limit and fix the shock absorber.
[0030] The limiting component 2 includes a top block 202, a guide arc surface 203, two sets of clamping arms 204 and an elastic element 206.
[0031] The top block 202 is movably disposed at one end of the clamping arm 204 to limit the clamping arm 204. Two sets of clamping arms 204 are arranged opposite to each other. Each set of clamping arms 204 can move around the fixed end 207. The guide arc surface 203 is formed on the side wall where the top block 202 contacts the clamping arm 204 to assist the clamping arm 204 in moving.
[0032] One end of each of the two sets of clamping arms 204 is connected by the elastic element 206. When the shock absorber is placed between the two sets of clamping arms 204, the elastic element 206 provides clamping force to the clamping arms 204.
[0033] Specifically, the opposing surfaces of the two sets of clamping arms 204 are arc-shaped surfaces that match the shock absorber cylinder body. The two work together to form a clamping cavity, achieving radial clamping of the shock absorber cylinder body. One end of the two sets of clamping arms 204 is connected by an elastic element 206, and the other end is an open end, which facilitates the insertion of the shock absorber. When the clamping arms 204 clamp and fix the shock absorber cylinder body, one end of the two sets of clamping arms 204 compresses the elastic element 206. The elastic element 206 generates elastic force that acts on the two sets of clamping arms 204, thereby providing continuous clamping force for the clamping arms 204, realizing adaptive clamping for shock absorbers with different outer diameters without the need for manual adjustment of the clamping amplitude.
[0034] Furthermore, the top block 202 is fixed to the fixing plate 201 by bolts, forming a block on one end of the two sets of clamping arms 204 where the elastic element 206 is provided, so that the clamping arms 204 can open and close within a specified stroke. While adapting to different specifications of shock absorber cylinders, it avoids the opening end of the clamping arm 204 from being over-opened and causing excessive compression to the elastic element 206. The opening of the guide arc surface 203, in conjunction with the clamping arm 204, can control different opening angles of the clamping arm 204, thus facilitating the adaptation to different specifications of shock absorber cylinders.
[0035] Furthermore, polyurethane buffer pads can be attached to the opposing surfaces of the two sets of clamping arms 204 to prevent scratches on the cylinder surface.
[0036] like Figures 1 to 4 As shown, in this embodiment, the limiting component 2 further includes a fixing plate 201, which is used to support the top block 202 and the clamping arm 204, and the fixing plate 201 is provided with a guide rail that cooperates with the top block 202 to guide and limit the top block 202.
[0037] Specifically, the guide rails on the fixed plate 201 guide and limit the top block 202, ensuring the straightness of the top block 202's movement and preventing deviation, so that the top block 202 has the same limiting effect on the two sets of clamping arms 204 on both sides.
[0038] like Figures 3 to 4 As shown, in this embodiment, the limiting component 2 further includes rollers 205, which are movably disposed at both ends of the clamping arm 204 and protrude from the end of the clamping arm 204.
[0039] Specifically, the roller 205 protruding from one end of the clamping arm 204 can prevent one end of the clamping arm 204 from directly contacting the top block 202, thereby ensuring that the clamping arm 204 can move smoothly along the guide arc surface 203. The roller 205 protruding from the other end of the clamping arm 204 can prevent the other end of the clamping arm 204 from directly contacting the shock absorber cylinder, thereby facilitating the insertion of the shock absorber cylinder between the clamping arms 204 and playing a guiding role.
[0040] like Figure 4 As shown, in this embodiment, the elastic element 206 is a spring.
[0041] Specifically, in this embodiment, the elastic element 206 is preferably a spring. Springs are standard parts, easy to obtain, and have low production costs and relatively low prices. While ensuring that a stable clamping force can be provided, they are also conducive to reducing the tooling manufacturing cost.
[0042] like Figures 1 to 2As shown, in this embodiment, the reference component 1 includes a base 101, a quick-release sleeve 102, and a support column 103. The quick-release sleeve 102 is disposed on the base 101 and is used to install the support column 103. One end of the support column 103 is detachably disposed inside the quick-release sleeve 102, and the other end is provided with a positioning groove that matches the shock absorber.
[0043] Specifically, when installing the shock absorber, one end of the shock absorber can be inserted into the positioning slot. The positioning slot is equipped with a positioning pin, which locks and fixes the positioning slot to the shock absorber. The support column 103 supports the shock absorber, so that the shock absorber is at the working point height, which facilitates subsequent processing.
[0044] Furthermore, since the support column 103 and the quick-release sleeve 102 are detachably connected, when the specifications of the shock absorber change, replacing the support column 103 will allow the shock absorber of different specifications to be at the appropriate height.
[0045] like Figures 1 to 2 As shown, in this embodiment, the reference component 1 further includes a guide frame 104, which is disposed on the base 101, and the limiting component 2 is slidably sleeved on the guide frame 104.
[0046] Specifically, the guide frame 104 provides vertical sliding guidance for the limiting component 2, ensuring the movement accuracy and stability of the limiting component 2.
[0047] like Figures 1 to 2 As shown, in this embodiment, the reference component 1 further includes a connecting rod 105 and a top cover placement column 106. The connecting rod 105 is detachably mounted on the guide frame 104 to support the top cover placement column 106, and the top cover placement column 106 is detachably mounted on the connecting rod 105.
[0048] Specifically, the top cover placement column 106 is used for temporary placement and pre-installation positioning of the shock absorber top cover, to avoid loss or damage to the top cover, improve assembly efficiency, and the detachable structure facilitates subsequent uniform replacement according to the specifications of the shock absorber top cover, further enhancing the tooling function and versatility.
[0049] like Figures 1 to 2 As shown, in this embodiment, the reference component 1 further includes a placement platform 107 and a coil clamping fixture 108. The placement platform 107 and the coil clamping fixture 108 are respectively disposed on the base 101. The placement platform 107 is used to temporarily store pre-installed valve components, and the coil clamping fixture 108 is used to precisely press-fit the shock absorber electromagnetic coil.
[0050] Specifically, the placement table 107 is used to store pre-assembled valve parts, which facilitates subsequent assembly. The coil clamping fixture 108 is used to precisely press the electromagnetic coil of the electronically controlled shock absorber, further expanding the function of the fixture and facilitating subsequent production processes.
[0051] like Figures 1 to 2 As shown, in this embodiment, the reference component 1 further includes a force detection unit 109, which is disposed on the base 101 and electrically connected to the coil clamping fixture 108. It is used to collect and display the pressing force data in real time, further expanding the function of the fixture and facilitating subsequent production processes.
[0052] Specifically, the force detection unit 109 is an FID force display module (abbreviated as FID, no specific full Chinese name, industry common code, used for real-time force detection and display), with a range of 0-20kN, an accuracy of 0.5%FS, and an over-tolerance audible and visual alarm function. It is integrated on the base 101 and electrically connected to the coil clamping fixture 108. It collects and displays the pressing force data in real time, realizing traceable control of process parameters.
[0053] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0054] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
