[0025] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] The utility model provides an electric vehicle front suspension subassembly auxiliary tool with an error-proofing function, which includes a tooling platform 1 and a support portion. The tooling platform 1 is slidably connected to the support portion. The support portion includes a bottom plate 2 and a first support column 3 distributed in a rectangular shape on the bottom plate 2. A second support column 4 corresponding to the first support column 3 is provided at the bottom of the tooling platform 1. The second support column 4 passes through the top of the first support column 3 and is slidably connected to the first support column 3 up and down.

[0027] The two first support columns 3 on the same side of the base plate 2 are connected by a connecting assembly, and the second support column moves up and down through the connecting assembly. The connecting assembly includes a roller screw 5, a first connecting rod 6, and a second connecting rod 7. The first connecting rod 6 and the second connecting rod 7 are located at both ends of the roller screw 5. The two ends of the first connecting rod 6 are connected to the second support column 4 and the roller screw 5. The threads at both ends of the roller screw 5 are rotated in opposite directions. Both ends of the roller screw 5 are provided with connecting blocks 14 corresponding to the threads. The upper and lower ends of the first connecting rod 6 are respectively hinged to the second support column 4 and the connecting block 14. The roller screw 5 is provided with parallel guide rods 15, and the connecting block 14 is slidably connected to the guide rod 15. The first connecting rod 6 and the second connecting rod 7 are respectively located at the upper and lower ends of the connecting block 14. The roller screw 5 drives the first connecting rod 6 and the second connecting rod 7 at both ends to perform linear motion;

[0028] The bottom of the base plate 2 is provided with a limiting assembly slidably connected to the second connecting rod 7 .

[0029] In this embodiment, a first placement rack 8 and a second placement rack 9 are provided on the tooling stand 1 . The first placement rack 8 is symmetrically arranged on both sides of the tooling stand 1 , and the second placement rack 9 is symmetrically arranged on both ends of the tooling stand 1 .

[0030] In this embodiment, the first placement rack 8 and the second placement rack 9 are arranged on the same horizontal plane. The top of the first placement rack 8 is provided with a contoured surface corresponding to the bottom end of the front and rear sides of the front suspension. The first placement rack 8 and the second placement rack 9 are provided with retaining edges that cooperate with the front suspension and the left and right lower control arms.

[0031] In this embodiment, positioning columns 10 corresponding to the second placement racks 9 are provided at both ends of the tooling stand 1 .

[0032] In this embodiment, a support seat 11 corresponding to the first placement rack 8 and the second placement rack 9 is provided on the tooling stand 1, and the first placement rack 8, the second placement rack 9 and the support seat 11 are movably connected and fixed by a first positioning pin 12 and a second positioning pin 13.

[0033] In this embodiment, a notch is provided on the top of the support seat 11 corresponding to the bottom of the first placement rack 8 and the second placement rack 9. The bottoms of the first placement rack 8 and the second placement rack 9 are inserted into the notch and fixed by the first positioning pin 12 and the second positioning pin 13.

[0034] In this embodiment, the first positioning pin 12 is located above the second positioning pin 13 .

[0035] In this embodiment, the limiting assembly includes a slide plate 16 and a support plate 17. The support plate 17 is located below the base plate 2. The inner end of the slide plate 16 is inclined and the other end is connected to 17 by a third connecting rod 18. The slide plate 16 is connected to the top of the base plate 2 by a spring 19. The base plate 2 is provided with a groove corresponding to the inclined portion of the slide plate 16. When the slide plate 16 slides downward under pressure, the inclined portion moves into the groove.

[0036] In this embodiment, a roller is provided at the bottom of the base plate 2, a push handle is provided on one side of the first support column 3, and the roller has a locking structure.

[0037] When used in this embodiment, the assembler places the front suspension assembly on the designated position of the tooling stand. The first placement rack 8 and the second placement rack 9 effectively support the front suspension assembly and can effectively lift it during subassembly. The front swing arm and other parts are sequentially subassembled on the front suspension assembly. The front swing arm is limited by the first placement rack 8 and the second placement rack 9. If the front swing arm is misassembled to the left or right, it cannot be placed in place on the tooling. The tooling is transported to the designated assembly position of the production line by the pusher. The locking structure locks the roller, and the motor drives the roller screw 5 to rotate. The rotation of the roller screw 5 drives the connecting blocks 14 at both ends to move along the guide The rod 15 moves to both sides, and the connecting block 14 drives the first connecting rod 6 to rotate during the movement. The first connecting rod 6 supports the second support column 4 upward so that the second support column 4 moves upward along the direction of the first support column 3, thereby driving the front suspension on the tooling platform 1 to move upward. At the same time, the second connecting rod 7 starts to slide along the slide plate 16, squeezing the slide plate 16. The slide plate 16 drives the support plate 17 downward through the third connecting rod 18. The support plate 17 touches the ground to further limit the tooling. When it rises to an appropriate height, the positioning column 10 is aligned with the positioning hole of the vehicle body and the bolts are tightened to connect the front suspension assembly and the vehicle body.

[0038] After completion, the motor drives the roller screw 5 to flip, the tooling platform 1 starts to descend, and the second connecting rod 7 no longer squeezes the slide 16. The slide 16 returns upward under the action of the spring 19, and the support plate 17 no longer supports the ground. The roller is unlocked and the tooling is moved;

[0039] When the first placement rack 8 and the second placement rack 9 are not needed for assembling other products, the first positioning pin 12 is taken out, the first placement rack 8 and the second placement rack 9 are rotated ninety degrees around the second positioning pin 13, and then the first positioning pin 12 is inserted into the corresponding positioning hole in the support seat 11. The first positioning pin 12 is located above the rotated first placement rack 8 and the second placement rack 9 to limit and fix the first placement rack 8 and the second placement rack 9.

[0040] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
