[0027] Before describing the embodiments of this utility model in detail, the application environment of this utility model will be described first. The technology of this utility model is mainly applied to the field of automotive design and manufacturing technology. This utility model is used to solve the problem that the existing installation equipment for MacPherson strut brakes and shock absorbers in passenger cars has high equipment costs, resulting in high production and manufacturing costs.

[0028] Please combine Figures 1 to 3 As shown, this utility model provides an auxiliary installation device for a MacPherson strut brake and shock absorber.

[0029] In an exemplary embodiment of this utility model, the auxiliary installation device for the MacPherson strut brake 101 and shock absorber 102 includes: an assembly table 1, which has a positioning groove for positioning and installing the brake 101, enabling quick positioning and installation of the brake 101 and the assembly table 1; a positioning mechanism 2, which is disposed on the assembly table 1 and is used to position and install the shock absorber 102, and the shock absorber 102 and the brake 101 are connected by a connector 5; a limiting mechanism 3, which is disposed on the assembly table 1 and is used to limit the brake 101 along its own circumferential and axial directions; and an anti-rotation mechanism 4, which is disposed on the assembly table 1 and is used to limit the connection 5 from rotating along its own circumferential direction when the shock absorber 102 and the brake 101 are connected by the connector 5.

[0030] In this embodiment, the brake 101 and the shock absorber 102 are respectively provided with holes for the connecting member 5 to pass through. The connecting member 5 includes, but is not limited to, bolts. In this embodiment, the connecting member 5 is a bolt as an example to illustrate the specific solution. Specifically, the shock absorber 102 is positioned and installed on the assembly table 1 by the positioning mechanism 2, so that the through hole on the shock absorber 102 can be quickly aligned with the through hole on the brake 101. After the alignment is completed, the shock absorber 102 is pressed and fixed on the assembly table 1 by the positioning mechanism 2. The brake 101 is limited along its own circumference and axial direction by the limiting mechanism 3, thereby preventing the brake 101 from rotating and tipping over during the assembly process of the shock absorber 102 and the brake 101. When the shock absorber 102 and the brake 101 are connected by the connecting member 5, the anti-rotation mechanism 4 cooperates with the connecting member 5 to limit the connecting member 5 from rotating along its own circumference, so as to prevent the connecting member 5 from rotating with the nut when the nut is tightened. The auxiliary installation device for the MacPherson strut brake 101 and shock absorber 102 shown in this embodiment has a simple structure, is easy and convenient to operate, has low equipment cost, and a short design and manufacturing cycle, thereby effectively reducing production and manufacturing costs.

[0031] In an exemplary embodiment of the present invention, the anti-rotation mechanism 4 includes a base 401, a slide 402, and a sleeve 403. The base 401 is connected to the assembly table 1, the slide 402 is slidably disposed on the base 401, and the sleeve 403 is disposed at one end of the slide 402 along the length direction. The sleeve 403 is used to detachably connect with the connector 5 to restrict the rotation of the connector 5.

[0032] In this embodiment, the height of the base 401 extends along the axial direction of the brake 101, such that the height of the slide 402 on the base 401 is flush with the height of the connection point between the shock absorber 102 and the brake 101 via the connector 5, thereby ensuring that the height of the sleeve 403 on the slide 402 is consistent with that of the connector 5; the base 401 is provided with a slide rail 401a, which extends along the length of the base 401, and the slide 402 is provided with a slider 402c, which slides slidably with the slide rail 401a. The sliding rail 401a and the slider 402c have good wear resistance and can be used for a long time without being easily damaged. By moving the sliding table 402, the sleeve 403 is brought close to the connector 5 and engages with the nut of the connector 5, so that the nut of the connector 5 enters the sleeve 403. The nut of the connector 5 has a polygonal structure, and the sleeve 403 is provided with a polygonal groove that matches the shape of the nut, which can effectively restrict the connector 5 from rotating around its own circumference, so that the connector 5 will not rotate with the nut during the locking process.

[0033] In an exemplary embodiment of the present invention, the anti-rotation mechanism 4 further includes a locking component for locking and fixing the slide 402 to the base 401.

[0034] In this embodiment, the locking assembly includes, but is not limited to, a strip groove provided on the base 401, and a locking member rotatably provided on the slide 402. The locking member is provided with a handle and a locking part. The locking part has an irregular structure. When the extension direction of the handle is parallel to the length direction of the slide 402, the locking part and the strip groove are in clearance fit. When it is necessary to lock the position of the slide 402 and the base 401, the handle is rotated so that the extension direction of the handle is perpendicular to the length direction of the slide 402. At this time, the locking part and the strip groove are in interference fit, thereby locking and fixing the slide 402 on the base 401.

[0035] In an exemplary embodiment of the present invention, the locking assembly includes a locking arm 405, which is connected to and slides synchronously with the slide table 402. The base 401 is provided with a plurality of locking positions 404a. When the locking arm 405 slides to one of the locking positions 404a, it locks and engages with the locking position 404a.

[0036] For example, the base 401 is provided with two locking positions 404a. The locking positions 404a include a first locking position close to the brake 101 and a second locking position away from the brake 101. When the brake 101 is assembled with the shock absorber 102, the slide 402 is moved toward the brake 101, so that the sleeve 403 engages with the connector 5. At this time, the locking arm 405 engages with the first locking position, thereby fixing the slide 402 in the working state. When the brake 101 and the shock absorber 102 are assembled, the locking arm 405 is unlocked from the first locking position, and the slide 402 is reset to the initial state. At this time, the locking arm 405 engages with the second locking position, thereby locking the slide 402 in the initial state.

[0037] In this embodiment, the locking assembly further includes a locking block 404, which is disposed on the base 401. A locking position 404a is disposed on the locking block 404, and the locking position 404a is a locking hole disposed on the locking block 404. A locking pin 405a is disposed on the locking arm 405. The locking pin 405a cooperates with the locking hole pin hole to fix the slide table 402 and the base 401. The locking arm 405 extends along the width direction of the slide table 402 and is slidably connected to the locking block 404. A through hole is opened on the locking arm 405 corresponding to the locking position 404a. The through hole is used to pass through the locking pin 405a. The locking pin 405a is used to cooperate with the locking position 404a with clearance. A limiting part is provided at one end of the locking pin 405a along the axial direction. The diameter of the limiting part is larger than the diameter of the locking position 404a and the through hole.

[0038] In an exemplary embodiment of the present invention, two blocks 404b are provided on the base 401 along the sliding direction of the slide table 402, and a locking arm 405 is slidably connected to the base 401 between the two blocks 404b, with a locking position 404a located between the two blocks 404b.

[0039] In this embodiment, the stop block 404b is used to block the locking arm 405. Since the locking arm 405 is connected to the slide table 402 and moves synchronously with the slide table 402, the stop block 404b blocks the locking arm 405, thereby limiting the movement stroke of the slide table 402 and preventing the slide table 402 from derailing from the slide rail 401a.

[0040] In an exemplary embodiment of the present invention, the slide table 402 is provided with an operating component 402a, which is used to transmit power to push the slide table 402 to move along the length direction of the slide table 402.

[0041] In this embodiment, the operating component 402a includes, but is not limited to, a cylindrical handle. The cylindrical handle is threadedly connected to the slide 402. The cylindrical handle facilitates manual gripping of the handle to push the slide 402 to the working position or pull it back to the initial position. The driving force used to drive the operating component 402a to move the slide 402 includes, but is not limited to, manual drive, cylinder drive, hydraulic drive, or servo drive.

[0042] In an exemplary embodiment of the present invention, a reinforcing member 402b is provided on the slide table 402.

[0043] In this embodiment, the bolt connection holes for installing the locking arm 405 and the handle are provided on the slide table 402, which affects the structural strength of the slide table 402. In this embodiment of the utility model, a reinforcing plate is provided on the slide table 402, thereby effectively improving the structural strength of the slide table 402 and thus increasing the service life of the anti-rotation mechanism 4.

[0044] In another exemplary embodiment of the present invention, the assembly table 1 is provided with a positioning groove, which is used to position and install the brake 101.

[0045] In this embodiment, the positioning groove is a contour groove designed according to the shape of the brake 101. Through the contour groove provided on the assembly table 1, the brake 101 and the assembly table 1 can be quickly positioned and assembled, effectively improving work efficiency.

[0046] In an exemplary embodiment of the present invention, the positioning mechanism 2 includes a positioning seat 201, a positioning block 202 and a positioning locking member. The positioning seat 201 is disposed on the assembly table 1. The positioning block 202 is hinged to the positioning seat 201. A space for installing the shock absorber 102 is provided between the positioning block 202 and the positioning seat 201. The positioning block 202 is locked to the positioning seat 201 by the positioning locking member.

[0047] In this embodiment, an arc-shaped mounting space for installing the shock absorber 102 is provided between the positioning block 202 and the positioning seat 201. The arc-shaped mounting space can effectively increase the contact area between the positioning block 202 and the shock absorber 102, increase the friction between the positioning block 202 and the shock absorber 102, and prevent the shock absorber 102 from rotating or moving between itself and the positioning mechanism 2 during installation. The positioning block 202 is hinged to the positioning seat 201, thereby allowing the arc-shaped mounting space for installing the shock absorber 102 between the positioning block 202 and the positioning seat 201 to be easily opened or closed, facilitating the installation of the shock absorber 102. The positioning locking component includes, but is not limited to, bolts. The positioning block 202 is connected and fixed to the positioning seat 201 through the positioning locking component, which can easily realize the locking and unlocking of the positioning block 202 and the positioning seat 201.

[0048] In an exemplary embodiment of the present invention, the limiting mechanism 3 includes a circumferential limiting component 301, which is hinged to the assembly table 1 and is used to abut against the brake 101.

[0049] In this embodiment, after the brake 101 is positioned and installed on the assembly table 1, the circumferential limiting component 301 hinged on the assembly table 1 rotates to abut against the brake 101, thereby effectively preventing the brake 101 from rotating on the assembly table 1 during the assembly process with the shock absorber 102.

[0050] In an exemplary embodiment of the present invention, the limiting mechanism 3 further includes an axial limiting component 302. One end of the axial limiting component 302 is hinged to the assembly table 1, and the other end of the axial limiting component 302 can be pressed against the top surface of the brake 101 to press and fix the brake 101 onto the assembly table 1.

[0051] In this embodiment, the brake 101 is pressed and fixed onto the assembly table 1 by the axial limiting component 302 provided on the assembly table 1, thereby preventing the brake 101 from tipping over on the assembly table 1 during the assembly process of the shock absorber 102. The axial limiting component 302 includes, but is not limited to, a quick-clamping device. The quick-clamping device shown in this embodiment includes a fixed base, a pressure block, and a wrench. The fixed base is provided on the assembly table 1 and has a hinge point for connecting with the pressure block and the wrench. One end of the pressure block is hinged to the fixed base, and the other end is used to contact and clamp the brake 101. The wrench is a component that provides operating torque, and the wrench and the pressure block form a certain lever relationship. By operating the wrench, the lifting and lowering control of the pressure block can be realized. When the quick-clamping device is not working, the pressure block is in a higher position, maintaining a certain distance from the brake 101. The wrench is in a naturally hanging or easily operable position. Operation process: The operator holds the wrench and pulls it downward (or according to the design direction). Because the wrench is hinged to the fixed base, and the pressure block is also hinged to the fixed base, the movement of the wrench will cause the pressure block to rotate around the hinge point. As the wrench continues to be turned, the pressure block gradually descends and contacts the brake 101. Due to the leverage effect created by the wrench, the operator can relatively easily apply sufficient pressure to firmly press the brake 101 onto the assembly table 1. When the pressure block reaches the pressed position, the wrench and pressure block can be locked in the current position by a locking mechanism (such as a locking pin, spring lock, etc.) to prevent accidental loosening. When it is necessary to release the brake 101, the operator only needs to reverse the operation of the wrench (i.e., turn it upwards) to make the pressure block gradually rise and move away from the brake 101.

[0052] The working principle is as follows: First, the brake 101 is installed in the positioning slot of the assembly table 1. The shock absorber 102 is then positioned on the assembly table 1 by the positioning mechanism 2, allowing the shock absorber 102 to quickly align with the brake 101 installed on the assembly table 1 and connect via the connector 5. The limiting mechanism 3 limits the brake 101 along its circumference and axial direction, thus preventing the brake 101 from rotating or tipping over during assembly. The anti-rotation mechanism 4, in cooperation with the connector 5, restricts the connector 5 from rotating along its circumference, preventing it from rotating with the nut during tightening. This utility model demonstrates a MacPherson strut brake 101 and shock absorber 102 auxiliary installation device with a simple structure, easy and convenient operation, low equipment cost, and short design and manufacturing cycle, thereby effectively reducing production costs.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
