Description

Technical Field

[0001] This utility model relates to the field of shock absorber tower clamping technology, and in particular to a processing clamping fixture for shock absorber towers of new energy vehicles. Background Technology

[0002] A shock absorber tower, also known as a damper tower or shock absorber tower, is part of a car's suspension system. Its main function is to secure one end (usually the top) of the shock absorber, thereby helping the shock absorber work more effectively. Shock absorber towers are typically located at the front and rear of the vehicle body and work in conjunction with the shock absorbers to improve vehicle stability and ride comfort.

[0003] The design and quality of shock absorber towers have a significant impact on a vehicle's handling performance. High-quality shock absorber towers can enhance body rigidity, reduce body twisting and deformation during driving, thereby improving overall vehicle stability and driving experience. Furthermore, some high-performance vehicles may use reinforced shock absorber towers or retrofitted towers to further enhance handling performance.

[0004] See appendix Figure 1 Appendix Figure 2 The diagram shows the structure of a shock absorber tower for a new energy vehicle. The shock absorber tower includes a main body, a top cover at the bottom of the main body, a positioning circle in the center of the top cover, and connecting edges and skirts on the edges of the main body. A five-axis machining center is needed to machine the planes and holes on the top cover.

[0005] Since the shock absorber tower is made of aluminum alloy, if no anti-deformation measures are taken during processing and it is directly clamped in the machining center, the shock absorber tower will be squeezed and deformed during clamping due to the limitations of the special material, which will affect the normal processing of the top cover's plane and holes.

[0006] Therefore, there is an urgent need for a processing fixture for shock absorber towers of new energy vehicles, which can effectively clamp and fix the shock absorber towers during the processing, prevent extrusion deformation, and improve the processing quality of the plane and holes of the top cover. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a processing fixture for shock absorber towers of new energy vehicles, which solves the problem that when shock absorber towers are clamped without any anti-deformation measures, the shock absorber towers are squeezed and deformed, affecting the normal processing of the top cover plane and holes.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A processing fixture for a shock absorber tower of a new energy vehicle includes a connecting plate, on which a base is detachably mounted. One end of the base is provided with two first mounting columns, and each of the two first mounting columns is provided with a first clamping drive cylinder. The output end of the first clamping drive cylinder is provided with a first pressure arm, which is used to apply a downward clamping force to the top cover.

[0010] The other end of the base is provided with two second mounting posts, and each of the two second mounting posts is provided with a second clamping drive cylinder. The output end of the second clamping drive cylinder is provided with a second pressure arm, which is used to apply a downward clamping force to the connecting edge.

[0011] The base is provided with a mounting platform between the two first mounting columns and the second mounting column, and the mounting platform is provided with a support unit in the direction of action of the first pressure arm and the second pressure arm.

[0012] The mounting platform is provided with a positioning post at the position of the positioning circle, and a positioning plate is provided on the positioning post. The positioning plate is conical.

[0013] The mounting platform is provided with at least one clamping drive cylinder on one side of the skirt. The output end of the clamping drive cylinder is provided with a clamping arm. The mounting platform is provided with multiple first supports at the positions corresponding to the clamping arms. The clamping arms and the first supports exert opposite forces on the skirt.

[0014] Furthermore, the support unit includes two second supports located below the first pressure arm and two support columns located below the second pressure arm.

[0015] Furthermore, the mounting platform is provided with a support drive cylinder between the two first mounting columns, and the output end of the support drive cylinder is provided with a support fork, and the support fork is provided with a V-shaped socket.

[0016] Furthermore, the mounting platform is also equipped with multiple third supports on one side of the clamping drive cylinder.

[0017] Furthermore, the first mounting post and the second mounting post are located on a virtual isosceles trapezoid.

[0018] Furthermore, the base is symmetrically provided with multiple limiting rods, and one end of each limiting rod is provided with a limiting head.

[0019] Furthermore, the connecting plate is provided with a T-shaped connecting groove, and the base and the connecting plate are bolted together through the T-shaped connecting groove.

[0020] Furthermore, a fourth support is inclinedly provided on both sides of the mounting platform, and the direction of movement of the fourth support is perpendicular to the connecting edge.

[0021] In summary, the beneficial technical effects of this utility model are as follows:

[0022] The first clamping drive cylinder, the second clamping drive cylinder, and the clamping drive cylinder respectively drive the first pressure arm, the second pressure arm, and the clamping arm to achieve inward clamping force on the top and sides of the shock absorber tower on the mounting platform. At the same time, the first support, the second support, the third support, the fourth support, and the support column on the mounting platform can provide inward support force on the shock absorber tower. This effectively fixes the shock absorber tower while avoiding squeezing deformation, further ensuring the quality of the top cover plane and hole processing. Attached Figure Description

[0035] The present invention will now be described clearly and completely with reference to the embodiments.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] See appendix Figure 1 Appendix Figure 2 The diagram shows the structure of a shock absorber tower for a new energy vehicle. The shock absorber tower includes a body 1, which is a hollow structure made of aluminum alloy. The body 1 has a top cover 2, a positioning circle 3 in the center of the top cover 2, a connecting edge 4 on the edge of the body 1, and a skirt 5 at one end of the body 1. The body 1 has multiple intersecting reinforcing ribs 6 and vertically arranged reinforcing columns 7 inside. Now, it is necessary to fix the shock absorber tower on a five-axis machining center to machine the plane and holes of the top cover 2.

[0039] See appendix Figure 3-11The image shows a processing fixture for a shock absorber tower of a new energy vehicle, including a connecting plate 8. The connecting plate 8 has multiple T-shaped connecting slots 30, and the connecting plate 8 is bolted to a base 9 through the T-shaped connecting slots 30. Two first mounting columns 10 are installed at one end of the base 9, and two second mounting columns 11 are provided at the other end of the base 9. The two first mounting columns 10 and the two mounting columns 11 are located on a virtual isosceles trapezoid. Each of the two first mounting columns 10 is provided with a first clamping drive cylinder 12. The output end of the first clamping drive cylinder 12 is provided with a first pressure arm 14, which is used to apply a downward clamping force to the top cover 2. Each of the two second mounting columns 11 is provided with a second clamping drive cylinder 13. The output end of the second clamping drive cylinder 13 is provided with a second pressure arm 15, which is used to apply a downward clamping force to the connecting edge 4.

[0040] It should be noted that both the first clamping drive cylinder 12 and the second clamping drive cylinder 13 are HSL series rotary cylinders.

[0041] The base 9 is located inside the virtual isosceles trapezoid where the first mounting column 10 and the second mounting column 11 are located. A positioning column 17 is located in the center of the mounting platform 16. A positioning plate 18 is elastically provided on the positioning column 17. The positioning plate 18 has a conical structure. In use, the entire shock absorber tower is mounted on the mounting platform 16 by cooperating with the positioning circle 3 of the top cover 2 through the positioning plate 18. A clamping drive cylinder 19 is provided on one side of the mounting platform 16 located on the skirt 5. A clamping arm 191 is provided at the output end of the clamping drive cylinder 19. A first support 20 is provided on the mounting platform 16 at the position corresponding to the clamping arm 191. The skirt 5 is clamped and fixed by the interaction force between the clamping arm 191 and the first support 20.

[0042] The mounting platform 16 is located below the first pressure arm 14 and is equipped with a second support 21. At the same time, a support column 22 is located below the second pressure arm 15. The support column is fixed to the base 9 by a connecting rod. The second support 21 can abut against the corresponding reinforcing rib 6 from the inside of the body 1 to provide an outward support force for the entire top cover 2. The support column 22 abuts against the bottom side of the connecting edge 4. This support force counteracts the downward clamping force of the first pressure arm 14 and the second pressure arm 15, thereby preventing the deformation of the top cover 2 and the connecting edge 4.

[0043] Therefore, it can be seen that the clamping drive cylinder 19 and the first support 20 cooperate to clamp and fix the skirt 5. The first pressing drive cylinder 12 drives the first pressing arm 14 and cooperates with the second support 21 to clamp and fix the top cover 2. The second pressing drive cylinder 13 drives the second pressing arm 15 and cooperates with the support column 22 to clamp and fix the connecting edge 4. This not only achieves the fixation of the entire shock absorber tower during the processing, but also avoids extrusion deformation and ensures the quality of the top cover 2's plane and hole processing.

[0044] Furthermore, the mounting platform 16 is provided with a support drive cylinder 25 between the two first mounting columns 10. The output end of the support drive cylinder 25 is provided with a support fork 26, and the support fork 26 is provided with a V-shaped socket 27. When the shock absorber tower is mounted on the mounting platform 16, the reinforcing column 7 inside the body 1 is inserted into the V-shaped socket 27. The support drive cylinder 25 drives the support fork 26 to apply an upward support force to the reinforcing column 7, and cooperates with the first pressing drive cylinder 12 and the second pressing drive cylinder 13 to further improve the stability of the shock absorber tower.

[0045] Further details can be found in the appendix. Figure 1 As can be seen, most of the structure of the entire shock absorber tower is concentrated on the side close to the clamping drive cylinder 19. Therefore, the mounting platform 16 is also arranged with multiple third supports 23 on the side of the clamping drive cylinder 19. The support area of ​​the shock absorber tower is increased by multiple third supports 23, which can prevent the clamping force from concentrating under the action of the clamping drive cylinder 19, causing the body 1 to deflect downward.

[0046] Furthermore, the mounting platform 16 is provided with fourth supports 24 on both sides at an angle. The fourth supports 24 can provide a vertical support force to the connecting edge 4 of the inclined part on the main body 1, thereby improving stability.

[0047] Furthermore, the base 9 is symmetrically provided with multiple limiting rods 28 on both sides of the width direction of the shock absorber tower. Each limiting rod 28 has a limiting head 29 at its end. The limiting head 29 can limit the left and right directions of the shock absorber tower and improve the reference for mounting on the mounting platform 16.

[0048] It should be noted that, in order to better control the action sequence of the first clamping drive cylinder 12, the second clamping drive cylinder 13, the clamping drive cylinder 19, the first support 20, the second support 21, the third support 23 and the fourth support 24, this utility model needs to be used in conjunction with a hydraulic sequence valve to control the action sequence.

[0049] In use, the first clamping drive cylinder 12 and the second clamping drive cylinder 13 drive the first pressure arm 14 and the second pressure arm 15 to rotate outward, and the clamping drive cylinder 19 drives the clamping arm 191 to open outward. Then, the entire shock absorber tower is mounted on the mounting platform 16 through the cooperation of the positioning circle 3 and the positioning plate 18 on the top cover 2. Next, the first clamping drive cylinder 12 and the second clamping drive cylinder 13 drive the first pressure arm 14 and the second pressure arm 15 to apply downward clamping force to the top cover 2 and the connecting edge 4, respectively. At the same time, the clamping drive cylinder 19 controls the clamping arm 191 to apply inward clamping force to the skirt 5. Then, the first support 20, the second support 21, the third support 23 and the fourth support 24 are activated in sequence through the sequence valve to provide support force from the inside to the outside to the skirt 5, the top cover 2 and the connecting edge 4, respectively. At this time, the entire shock absorber tower is fixed under the interaction of internal and external forces.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
