Description

Technical Field

[0001] This invention relates to the field of suspension bracket positioning fixture technology, and more specifically to the assembly fixture for rear suspension process components. Background Technology

[0002] The rear suspension assembly of a car plays a role in supporting and fixing the driver and absorbing vibration. Due to the extension of car models, there are many types of connecting brackets for the rear suspension assembly when installing them with the car frame. In order to facilitate differentiation, it is necessary to make a differentiation list and manually distinguish them by marking each part. However, problems such as incorrect installation and poor assembly stability often occur.

[0003] A search revealed that invention publication CN 109807529 A discloses a welding fixture for a suspension bracket. The long side of an L-shaped pressure block is bent downwards to form a clamping flange, which faces the top surface of the platform. A pressure block is located directly behind the L-shaped pressure block, with one parallel side of its long side serving as the clamping end. This welding fixture can position and clamp the main component and two smaller components together for subsequent welding, thus ensuring welding accuracy and effectively overcoming the shortcomings of existing methods that cannot guarantee welding accuracy.

[0004] The aforementioned patent documents use the radial movement of pistons in multiple cylinders to clamp the suspension bracket, facilitating stable fixation. However, this technical solution cannot identify different models of suspension brackets. When fixing a specific model of suspension bracket according to order requirements, if other models of suspension brackets are incorrectly installed, it only clamps one position of the suspension bracket and cannot identify the incorrectly installed model. Therefore, this application proposes a foolproof tooling for rear suspension brackets to effectively distinguish rear suspension brackets and ensure assembly stability. Summary of the Invention

[0005] This invention proposes a rear suspension process assembly fixture, which solves the problems mentioned in the background art.

[0006] The technical solution of this invention is implemented as follows:

[0007] The rear suspension assembly fixture includes a base plate and fixture supports. Each side of the base plate has a fixture support, which supports the balance bracket of the suspension bracket for balancing purposes. The fixture supports are inverted T-shaped, and the top of the two inverted T-shapes has lifting plates facing away from each other, which are used to support the bottom plane of the balance bracket of the suspension bracket. Each side of the lifting plate has an upwardly protruding positioning pin, which positions the positioning pin with the mounting hole on the bottom plane of the balance bracket of the suspension bracket.

[0008] The tooling support is provided with a support beam frame located at the bottom of the lifting plate. A flipping arm rotates in the support beam frame. A foolproof fixing plate is provided on one side of the flipping arm between the support beam frame and the tooling support. A foolproof pin is provided on each side of the foolproof fixing plate, which can be adjusted radially to position the mounting hole in the inner side of the balance bracket of the suspension bracket. The other side of the flipping arm protrudes from the support beam frame to adapt to the bottom plane of the suspension bracket.

[0009] Furthermore, the side of the beam support away from the anti-foolproof fixing plate is flush with the side of the two lifting plates away from each other, which facilitates the formation of a vertical angle to adapt to the inner space of the balance support of the suspension bracket.

[0010] Furthermore, the tilting arm is L-shaped, with one side located in the beam support frame and the other side located away from the anti-foolproof fixing plate.

[0011] Furthermore, the tilting arm is located on one side of the beam support frame near the L-shaped angle by a rotating shaft, with both sides of the rotating shaft extending to the inside of the beam support frame and rotating therewith.

[0012] Furthermore, the beam support frame is provided with a movable opening, and the tilting arm is located on one side of the beam support frame and tilts within the movable opening.

[0013] Furthermore, the tilting arm is located on one side of the beam support frame with the same thickness as the beam support frame. When the tilting arm is rotated to be flush with the beam support frame, it facilitates the alignment of the plane of the anti-foolproof fixing plate with the plane of the beam support frame, thereby improving the positioning accuracy of the anti-foolproof pin on the anti-foolproof fixing plate with the mounting hole on the inner side of the balance bracket of the suspension bracket.

[0014] Furthermore, each of the two tooling supports has an opening on the opposite side that contacts the base plate, which provides installation space when the counterweight is installed on the side of the rotating arm away from the anti-foolproof fixing plate.

[0015] Furthermore, there is an movable channel between the beam support frame and the tooling support, and the anti-foolproof fixing plate is located in the movable channel, which facilitates the flipping arm to move the anti-foolproof fixing plate freely in the flipping arm and also restricts the degree of freedom of the rotating arm.

[0016] Furthermore, each of the two tooling supports has a clearance hole on its opposite side to accommodate the anti-misalignment pin, preventing the anti-misalignment pin from protruding after adjustment and causing rotational interference or collision and wear of the tooling support.

[0017] Furthermore, each side of the anti-foolproof fixing plate is threaded with a headless screw for threaded fastening of the anti-foolproof pin that is adjusted to a specified length.

[0018] The beneficial effects of the technical solution provided in this application are as follows:

[0019] 1. The assembly tooling for the rear suspension process uses the tooling support as the installation support base for the suspension bracket. The top of the tooling uses a lifting plate to make the top of the balance bracket of the suspension bracket flat and stable within the vertical angle. The mounting holes of the balance bracket are positioned by positioning pins, so that the supporting beam is flush with and perpendicular to the lifting plate, forming a 90-degree support component. This ensures that the inner side of the vertical angle of the balance bracket of the suspension bracket fits perfectly, facilitating installation.

[0020] 2. This rear suspension assembly fixture features a rotatable L-shaped tilting arm mounted on the support beam. The protruding side of the L-shape supports the bottom of the suspension bracket. The anti-misalignment plate on the tilting arm rotates with the arm until its flat surface is against the inner surface of the support beam. Anti-misalignment pins on the anti-misalignment plate ensure horizontal alignment and allow insertion into the mounting holes of the suspension bracket's balance bracket. Different suspension bracket models have different mounting hole orientations for the balance brackets. Users can adjust the orientation of the anti-misalignment pins according to the different suspension bracket models to facilitate rapid positioning of the suspension bracket and ensure quick identification of incorrectly assembled suspension brackets, thus improving production efficiency.

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1-5 The rear suspension assembly fixture includes a base plate 1 and fixture supports 2. A fixture support 2 is provided on each side of the base plate 1, providing support and balance for the installation of the suspension bracket's balance support, ensuring stability and safety during assembly. The fixture supports 2 are inverted T-shaped, with lifting plates 3 facing away from each other at the top of the two inverted T-shapes. The inverted T-shaped fixture supports 2 and lifting plates 3 can accurately position and support the bottom plane of the suspension bracket's balance support, ensuring assembly accuracy and quality. Each side of the lifting plates 3 has upward-protruding positioning pins 4, allowing the positioning pins 4 to accurately position the mounting holes on the bottom plane of the suspension bracket's balance support, improving assembly accuracy and efficiency, reducing assembly difficulty and the possibility of errors. This assembly fixture effectively supports the suspension bracket's balance support, making the assembly process more stable and efficient for workers.

[0032] The tooling support 2 is equipped with a support beam 5 located at the bottom of the lifting plate 3. A rotating arm 6 is rotatably mounted on the support beam 5. On one side of the rotating arm 6, there is a foolproof fixing plate 7 located between the support beam 5 and the tooling support 2. Each side of the foolproof fixing plate 7 is equipped with a radially adjustable foolproof pin 8, which positions the mounting hole in the inner side of the balance bracket of the suspension bracket. The radially adjustable foolproof pin 8 can position the mounting hole in the inner side of the balance bracket of the suspension bracket, ensuring the assembly accuracy and consistency of the tooling. The other side of the rotating arm 6 protrudes from the support beam 5 to fit and contact the bottom plane of the suspension bracket, thereby more stably supporting the balance bracket of the suspension bracket, improving assembly accuracy and safety. The support beam 5 provides additional support and stability, increasing the load-bearing capacity and service life of the tooling.

[0033] In this embodiment, the side of the supporting beam 5 away from the anti-foolproof fixing plate 7 is flush with the side of the two lifting plates 3 that are away from each other, which facilitates the formation of a vertical angle. This is used to adapt to the inner space of the balance bracket of the suspension bracket, improving the applicability and flexibility of the assembly. It can increase the stability of the assembly tooling, reduce shaking and errors during the assembly process, and the flush design of the supporting beam 5 and the lifting plates 3 makes the operation of the assembly tooling more convenient, reduces the labor intensity of the operators, and improves work efficiency.

[0034] In this embodiment, the tilting arm 6 is L-shaped, with one side located in the supporting beam frame 5 and the other side located away from the anti-foolproof fixing plate 7. Because the tilting arm 6 is L-shaped and one side is located in the supporting beam frame 5, the stability of the support can be increased, avoiding accidents caused by the instability of the support. The L-shaped tilting arm 6 can bear greater weight, thereby improving the load-bearing capacity of the support. Since one side of the tilting arm 6 is located in the supporting beam frame 5, the space occupied by the support can be reduced, making the support more compact.

[0035] In this embodiment, the tilting arm 6 is located on one side of the beam support frame 5 near the L-shaped angle. A pivot 14 is provided, with both sides of the pivot 14 extending into the inner sides of the beam support frame 5 and rotating therewith. Since the tilting arm 6 can rotate around the pivot 14, the flexibility of the support is improved. The design of the pivot 14 makes the rotation of the tilting arm 6 more convenient and stable, improving the convenience and accuracy of operation. Due to the design of the pivot 14, the tilting arm 6 can be more tightly integrated with the beam support frame 5, reducing the space occupied and improving the compactness of the support. By setting the pivot 14, the swaying of the tilting arm 6 can be reduced, and the stability of the support can be improved.

[0036] In this embodiment, the beam support frame 5 is provided with a movable opening 9. The tilting arm 6 is located on one side of the beam support frame 5 and tilts within the movable opening 9. The movable opening 9 allows the tilting arm 6 to tilt in different positions, improving the adaptability and flexibility of the tooling. The tilting arm 6 tilts within the movable opening 9 without occupying additional space, saving space on the assembly site. The movable opening 9 also makes the tilting of the tilting arm 6 more convenient, allowing operators to more easily adjust its position, thus improving operational convenience and efficiency. By adjusting the tilting position of the tilting arm 6, the position and angle of the tooling installation process can be better controlled, improving assembly accuracy and efficiency.

[0037] In this embodiment, the flip arm 6 is located on one side of the beam support frame 5 and has the same thickness as the beam support frame 5. When the flip arm 6 is rotated to be flush with the beam support frame 5, it facilitates the alignment of the plane of the anti-foolproof fixing plate 7 with the plane of the beam support frame 5, thereby improving the positioning accuracy of the anti-foolproof pin 8 on the anti-foolproof fixing plate 7 with the mounting hole on the inner side of the balance bracket of the suspension bracket.

[0038] In this embodiment, each of the two tooling supports 2 has an opening 10 on the opposite side that contacts the base plate 1. The opening 10 provides installation space when a counterweight is installed on the side of the flipping arm 6 away from the anti-foolproof fixing plate 7. By installing the counterweight, the balance and stability of the tooling support can be adjusted to adapt to different workpiece processing requirements. If the anti-foolproof plate side of the flipping arm 6 is too heavy and additional force is required when installing the suspension bracket, a counterweight can be installed here. The opening 10 is to provide a certain installation space for the counterweight.

[0039] In this embodiment, there is a movable channel 11 between the beam support 5 and the tooling support 2. The anti-foolproof fixing plate 7 is located in the movable channel 11, which facilitates the flipping arm 6 to move the anti-foolproof fixing plate 7 freely within the flipping arm 6. The movable channel 11 can ensure that the position and orientation of the anti-foolproof fixing plate 7 between the beam support 5 and the tooling support 2 meet the requirements. The free movement of the anti-foolproof fixing plate 7 in the movable channel 11 can reduce jamming and friction during the assembly process, reduce assembly difficulty, improve operation convenience, and restrict the degree of freedom of the flipping arm 6. The restriction effect can ensure the stability of the position and posture of the workpiece during the processing.

[0040] In this embodiment, each of the two tooling supports 2 has a clearance hole 12 on its opposite side to accommodate the anti-misalignment pin 8. This prevents the anti-misalignment pin 8 from protruding after adjustment, causing rotational interference or collision and wear with the tooling support 2, thereby extending the product's service life. It can also reduce surface wear and deformation of the anti-misalignment pin 8. The clearance hole 12 can ensure that the position and orientation of the anti-misalignment pin 8 on the tooling support 2 meet the requirements, thereby improving the accuracy and stability of the entire assembly. Since the collision between the anti-misalignment pin 8 and the tooling support 2 is effectively avoided, the maintenance cost and failure rate of the anti-misalignment pin 8 during use can be reduced, and the overall maintenance cost of the assembly tooling can be lowered.

[0041] In this embodiment, a headless screw 13 is threaded on each side of the anti-misalignment fixing plate 7. This headless screw is used to tighten the anti-misalignment pin 8, which is adjusted to a specified length. This ensures that the length of the anti-misalignment pin 8 meets the requirements, thereby improving the accuracy and stability of the entire assembly, shortening the assembly time, and increasing production efficiency. Using the headless screw 13 can simplify the assembly process, reduce the number of required parts and assembly steps, thereby reducing production costs. The thread tightening of the anti-misalignment pin 8 can prevent assembly failure of the suspension bracket due to loosening.

[0042] exist Figure 5 , Figure 6 and Figure 7 In the process, the diameter of the mounting hole on the side of the balance bracket of the suspension bracket should be larger than the outer diameter of the anti-misalignment pin 8. This is to facilitate the compensation of the movement trajectory of the anti-misalignment pin 8 around the rotating shaft 14 during the assembly process by utilizing the larger diameter of the mounting hole, thereby avoiding wear between the outer edge of the anti-misalignment pin 8 and the inner side of the mounting hole.

[0043] exist Figure 6 , Figure 7 In this case, the balance brackets of suspension bracket 1" and suspension bracket 2 are respectively installed on the tooling support 2. The mounting holes on the sides of the balance brackets of suspension bracket 1" and suspension bracket 2 are in different positions. When it is necessary to install and process a certain type of suspension bracket, it is only necessary to adjust the corresponding anti-misalignment pin 8 to extend it to achieve accurate assembly. This can not only identify the assembly errors of other types of suspension brackets and quickly replace the suspension brackets, but also ensure the accurate installation of the corresponding suspension brackets.

[0044] In this embodiment, the tilting arm 6 is provided with a foolproof fixing plate 7 on one side of the supporting beam frame 5. Normally, when the suspension bracket is not installed, the side of the tilting arm 6 is unbalanced, and the tilting arm 6 will tilt up. The foolproof pin 8 on the foolproof fixing plate 7 will simultaneously tilt into the moving channel 11. When the suspension bracket is installed, the tilting arm 6 will be pressed horizontally under its own weight, causing the foolproof pin 8 to be pushed out and locked into the mounting hole on the side of the balance bracket on the suspension bracket.

[0045] This assembly fixture effectively prevents mistaken mounting on the suspension bracket, is universally applicable to various products, facilitates product handling, requires no human intervention, and effectively improves work efficiency while reducing the labor intensity of assembly personnel.

[0046] The working principle of this embodiment is as follows:

[0047] (1) Installation preparation: Different models of suspension brackets have mounting holes in different directions on the side of the balance bracket. According to the mounting holes of the corresponding model of suspension bracket, adjust the anti-fool pin 8 by using the headless screw 13, adjust the length of the anti-fool pin 8 on one side to extend out, and adjust the remaining anti-fool pin 8 back until it is flush with the anti-fool fixing plate 7, and lock it with the headless screw 13.

[0048] (2) Installation: Align the top mounting hole of the balance bracket of the suspension bracket with the positioning pin 4. In addition, align the bottom of the suspension bracket with the protruding side of the flip arm 6. After alignment, place the suspension bracket so that the balance bracket on the suspension bracket is placed flat on the top of the lifting plate 3. Ensure that the vertical angle of the inner side of the balance bracket on the suspension bracket is attached to the 90-degree support formed between the beam frame 5 and the lifting plate 3. Through the gravity of the suspension bracket, the flip arm 6 of the suspension bracket is subjected to force and rotates in the beam frame 5 using the rotating shaft 14. The flip arm 6 drives the anti-foolproof fixing plate 7 to move synchronously. When the flip arm 6 is located on one side of the beam frame 5 and flips to be completely parallel to the beam frame 5, the plane of the anti-foolproof fixing plate 7 is flush with the inner plane of the beam frame 5. Then the anti-foolproof pin 8 on the anti-foolproof fixing plate 7 rotates from the movable channel 11 to be inserted into the side mounting hole of the balance bracket on the suspension bracket, thereby achieving the limiting of the suspension bracket of this model.

[0049] (3) Identify whether the suspension bracket is installed incorrectly: The mounting holes on the side of the balance bracket on suspension bracket 1" and suspension bracket 2" are not in the same position. If a misalignment pin 8 is set to extend to the position of the mounting hole on the side of the balance bracket on suspension bracket 1", the side mounting hole on the balance bracket on suspension bracket 1" is matched with the position of the misalignment pin 8 and can be installed smoothly. If the mounting hole on the side of the balance bracket on suspension bracket 2" is not matched with the position of the misalignment pin 8, the installation process of suspension bracket 2" will fail due to the misalignment of the misalignment pin 8. The operation is simple. The employee only needs to place the suspension bracket on the assembly fixture. If the model is matched, the assembly is successful. If the model is not matched, the assembly will fail. If the model is identified as a suspension bracket with an incorrect model, the corresponding model can be replaced to complete the assembly. The assembly fixture does not require external pneumatic, electric or human intervention support.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
