Description

Technical Field

[0001] This invention relates to the field of tooling and fixture technology, and more specifically, to a tooling and fixture for assembling an automobile chassis. Background Technology

[0002] Welding of the front subframe of an automobile chassis is a critical step in automobile manufacturing. As an important component connecting the suspension, steering, and other systems, the front subframe plays a role in distributing loads and improving handling stability. Currently, when welding the main body parts of an automobile chassis, the parts must be fixed in place before welding can be carried out.

[0003] However, traditional car chassis lack a structure that can automatically adapt to the shape of the car chassis during assembly. In other words, existing technology can only use clamps with fixed structures to hold the car chassis. Due to unsuitable width, the area of ​​the car chassis covered by the clamps is too large, and it is impossible to reduce the area of ​​the car chassis not being clamped by structural contraction. This causes the clamps to cover the car chassis assembly, thus affecting the scope of the car chassis assembly and causing unnecessary impacts on the car chassis assembly process.

[0004] To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0005] This invention provides a tooling fixture for assembling an automobile chassis, in order to solve the technical problem mentioned in the background art that the lack of a structure that can automatically correspond to the shape of the automobile chassis during assembly affects the assembly range of the automobile chassis.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tooling fixture for assembling an automobile chassis, comprising a base, a processing table fixedly mounted on the top of the base, and clamping plates slidably mounted on both sides of the processing table. A top-support clamping mechanism is provided inside the clamping plate, and a release mechanism is provided at the bottom of the clamping plate. The top-support clamping mechanism and the release mechanism can bring the clamp composed of multiple supporting components close to and fit against the surface of the automobile chassis, and form a lock by reverse squeezing the clamp through the area of ​​the automobile chassis surface. The part that is not squeezed is pulled back and removed, so that only the part in contact with the surface of the automobile chassis is clamped stably.

[0007] In a preferred embodiment, the top support clamping mechanism includes a motor fixedly installed inside the base. A first gear is fixedly installed at the output end of the motor. The first gear is arranged in a vertical position. A second gear meshes with the top of the first gear. Rotary rods are fixedly installed on both sides of the second gear. The rotary rods are rotatably installed inside the processing table. Threaded grooves are opened on both sides of the rotary rods. Clamping plates are threadedly connected to both sides of the rotary rods respectively.

[0008] In a preferred embodiment, multiple sleeves are slidably installed on the inner walls of the two clamping plates, the multiple sleeves are arranged horizontally, and sliding push rods are slidably installed on the inner walls of the multiple sleeves. A pad is fixedly installed on one side of the multiple sliding push rods, the multiple pads are arranged vertically, and a support spring is fixedly installed on the other side of the multiple sliding push rods. The multiple support springs are located inside the sleeves.

[0009] In a preferred embodiment, one end of each of the plurality of sleeves is provided with a top pad block, one side of each of the plurality of top pad blocks is fixedly installed with a pressure pad spring, one end of each of the plurality of pressure pad springs is fixedly installed with a rear top cylinder, the rear top cylinder is fixedly installed on the outer wall of the sleeve, and the rear top cylinder is slidably installed on the inner wall of the clamping plate.

[0010] In a preferred embodiment, pull ropes are fixedly installed on the outer walls of the plurality of rear top cylinders, the pull ropes extend outward from the outside of the clamping plate, the outer walls of the plurality of pull ropes are provided with rollers, the outer walls of the plurality of rollers are fixedly installed with positioning plates, the plurality of positioning plates are arranged horizontally, the plurality of positioning plates are staggered from each other, and the bottom of the plurality of pull ropes is fixedly installed with a heavy pull block.

[0011] In a preferred embodiment, push springs are fixedly installed on both sides of the inner side of the top pad block, and limit blocks are fixedly installed on one side of each of the two push springs. The two limit blocks are slidably installed on both sides of the top pad block and are arranged symmetrically. Openings are provided on both sides of the rear top cylinder, and the openings cooperate with the limit blocks. A slot is provided on one side of each of the two openings, and the two slots are opened on the inner wall of the clamping plate. The slots cooperate with the limit blocks.

[0012] In a preferred embodiment, the release mechanism includes top pressure strips located on the outer walls of a plurality of rear top cylinders, the outer walls of the plurality of top pressure strips being in contact with the outer walls of the plurality of rear top cylinders, a pull frame being fixedly installed on one side of the plurality of top pressure strips, a lifting plate being fixedly installed at the bottom of the pull frame, and the lifting plate being slidably installed on the bottom inner wall of the clamping plate.

[0013] In a preferred embodiment, the lifting plate is horizontally positioned, with a slot on one side and a locking plate at the bottom. The locking plate engages with the slot on the lifting plate, and a support plate is provided on one side of the locking plate. The support plate is fixedly installed on the outer wall of the base, and the outer wall of the support plate is in contact with the outer wall of the locking plate.

[0014] The technical effects and advantages of this invention are as follows: The top support clamping mechanism and release mechanism of this invention use two clamping plates to drive multiple sleeves, sliding push rods and pads to approach and fit against the car chassis. When they are subjected to the reverse pressure of the car chassis surface, they stop and lock. The remaining sliding push rods and pads are pulled back after extending to their ends, thereby detaching from the car chassis. This results in only the clamped parts of the car chassis having supported pads, while the uncontacted parts retract to reduce the area of ​​the car chassis that is not clamped, thus avoiding unnecessary impact on the assembly range of the car chassis.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0024] Traditional automotive chassis assembly lacks a structure that automatically adapts to the shape of the chassis. Existing technology relies solely on fixed clamps to hold the chassis. However, inappropriate clamp widths result in excessive coverage of the chassis by the clamps, and the un-clamped area cannot be reduced through structural contraction. This obstruction hinders chassis assembly, affecting the assembly process and causing unnecessary disruptions. To address this issue, the following technical solution is proposed: Refer to the instruction manual appendix Figures 1-7 A type of tooling fixture for assembling automobile chassis, such as Figure 1 and Figure 2 As shown, the system includes a base 1, a processing table 2 fixedly mounted on the top of the base 1, and clamping plates 3 slidably mounted on both sides of the processing table 2. The clamping plate 3 has a top support clamping mechanism 4 inside and a release mechanism 5 at the bottom of the clamping plate 3. The top support clamping mechanism 4 and the release mechanism 5 can bring the clamp composed of multiple support components close to the surface of the car chassis, and form a lock by reverse squeezing the clamp through the area of ​​the car chassis surface. The part that is not squeezed is pulled back and removed, so only the part in contact with the surface of the car chassis is clamped stably.

[0025] like Figure 2 and Figure 3 As shown, the top support clamping mechanism 4 includes a motor 41 fixedly installed inside the base 1. A first gear 42 is fixedly installed at the output end of the motor 41. The first gear 42 is set in a vertical position. A second gear 43 meshes with the top of the first gear 42. Rotary rods 44 are fixedly installed on both sides of the second gear 43. The rotating rods 44 are rotatably installed inside the processing table 2. Threaded grooves are opened on both sides of the rotating rods 44. A clamping plate 3 is threadedly connected to both sides of the rotating rods 44 respectively. When the motor 41 starts, it drives the first gear 42 to rotate, which in turn drives the second gear 43 to rotate the rotating rod 44. The rotating rod 44 then drives the clamping plates 3 on both sides to move closer together and clamp the car chassis.

[0026] like Figure 3 and Figure 4 As shown, multiple sleeves 45 are slidably installed on the inner walls of the two clamping plates 3 respectively. The multiple sleeves 45 are set in a horizontal state. Sliding push rods 46 are slidably installed on the inner walls of the multiple sleeves 45. A pad 47 is fixedly installed on one side of the multiple sliding push rods 46. The multiple pads 47 are arranged vertically. A support spring 48 is fixedly installed on the other side of the multiple sliding push rods 46. The multiple support springs 48 are located inside the sleeves 45. The two clamping plates 3 drive multiple sleeves 45, sliding push rods 46 and pads 47 to approach and fit against the car chassis. The sliding push rods 46, which are subjected to the reverse pressure of the car chassis surface, move backward to compress the support springs 48.

[0027] like Figure 4 and Figure 5 As shown, one end of a plurality of sleeves 45 is provided with a top pad 49, a pressure pad spring 410 is fixedly installed on one side of the plurality of top pads 49, a rear top cylinder 411 is fixedly installed on one end of the plurality of pressure pad springs 410, the rear top cylinder 411 is fixedly installed on the outer wall of the sleeve 45, and the rear top cylinder 411 is slidably installed on the inner wall of the clamp plate 3. As the sliding push rod 46 moves backward, the support spring 48 presses the top pad block 49 to move backward simultaneously and compresses the pressure pad spring 410, thereby causing the top pad block 49 to move backward within the rear top cylinder 411.

[0028] like Figure 4 and Figure 5 As shown, multiple rear top cylinders 411 are fixedly installed with pull ropes 412 on their outer walls. The pull ropes 412 extend out of the outside of the clamp plate 3. The outer walls of the multiple pull ropes 412 are provided with rotating wheels 413. The outer walls of the multiple rotating wheels 413 are fixedly installed with positioning plates 414. The multiple positioning plates 414 are set in a horizontal state and are staggered with each other. The bottom of the multiple pull ropes 412 is fixedly installed with heavy pull blocks 415. Multiple heavy pull blocks 415 pull the rear top cylinder 411 through the pull rope 412 and the rotating wheel 413, and the rear top cylinder 411 that is not locked moves backward synchronously.

[0029] like Figure 4 and Figure 5 As shown, push springs 416 are fixedly installed on both sides of the inside of the top pad block 49. Limiting blocks 417 are fixedly installed on one side of the two push springs 416. The two limiting blocks 417 are slidably installed on both sides of the top pad block 49. The two limiting blocks 417 are arranged symmetrically. Openings are opened on both sides of the rear top cylinder 411. The openings cooperate with the limiting blocks 417. A slot 418 is provided on one side of the two openings. The two slots 418 are opened on the inner wall of the clamp plate 3. The slots 418 cooperate with the limiting blocks 417. At this time, the pushing spring 416 inside the top pad 49 drives the top limiting block 417 to extend. After the top limiting blocks 417 on both sides extend, the top cylinder 411 is locked into the slot 418 to lock the top pad 49 and the rear top cylinder 411.

[0030] like Figure 6 and Figure 7 As shown, the release mechanism 5 includes top pressure strips 51 located on the outer walls of multiple rear top cylinders 411. The outer walls of the multiple top pressure strips 51 are in contact with the outer walls of the multiple rear top cylinders 411. A pull frame 52 is fixedly installed on one side of the multiple top pressure strips 51. A lifting plate 53 is fixedly installed at the bottom of the pull frame 52. The lifting plate 53 is slidably installed on the bottom inner wall of the clamp plate 3. The lifting plate 53 drives the pulling frame 52 to keep the multiple top pressure strips 51 in position, and the multiple top pressure strips 51 press against the multiple rear top cylinders 411.

[0031] like Figure 6 and Figure 7 As shown, the lifting plate 53 is set in a horizontal state. A slot is provided on one side of the lifting plate 53. A locking plate 54 is provided at the bottom of the lifting plate 53. The locking plate 54 cooperates with the slot of the lifting plate 53. A support plate 55 is provided on one side of the locking plate 54. The support plate 55 is fixedly installed on the outer wall of the base 1. The outer wall of the support plate 55 is in contact with the outer wall of the locking plate 54. The lifting plate 53 is fixed by the locking plate 54. After the clamp plate 3 approaches the outer wall of the base 1, the locking plate 54 is squeezed and moves downward near the outer wall of the support plate 55, that is, the locking plate 54 is released from the slot of the lifting plate 53.

[0032] In practical implementation, the motor 41 starts, driving the first gear 42 to rotate, which in turn drives the second gear 43 to rotate the rotating rod 44. The rotating rod 44 then drives the clamping plates 3 on both sides to move closer together and clamp the car chassis. At this time, the two clamping plates 3 drive multiple sleeves 45, sliding push rods 46, and pads 47 to move closer and fit against the car chassis. The sliding push rods 46, which are subjected to the reverse pressure from the surface of the car chassis, move backward and compress the support springs 48. When the sliding push rods 46 move backward, the support springs 48 press against the top pads 49 and move backward simultaneously, pressing down. When the compression pad spring 410 is applied, the lifting plate 53 is first fixed by the locking plate 54, which then drives the pull frame 52 to keep the multiple top pressure strips 51 in position. The multiple top pressure strips 51 press against the multiple rear top cylinders 411, so that the top pad block 49 moves backward in the rear top cylinder 411. At this time, the pushing spring 416 in the top pad block 49 drives the top limiting block 417 to extend. The top limiting blocks 417 on both sides extend out of the rear top cylinder 411 and are inserted into the slot 418 to lock the top pad block 49 and the rear top cylinder 411. Multiple heavy pull blocks 415 pull the top cylinder 411 through the pull rope 412 and the rotating wheel 413. The un-clamped top cylinder 411 moves backward synchronously. The un-clamped top cylinder 411 drives multiple sleeves 45, sliding push rods 46 and pads 47 to move backward and withdraw synchronously. This results in only the clamping positions of the pads 47 on the car chassis being supported, while the non-contacting positions shrink to reduce the area of ​​the car chassis that is not clamped, thus avoiding unnecessary impact on the assembly range of the car chassis.
