[0007] Furthermore, the front bumper positioning and clamping assembly includes a fixed frame fixedly mounted on a support rod; a bumper bottom support block is provided at the lower part of the fixed frame, the bumper bottom support block is inclined and its inclination angle is adjustable to match the front bumper of the corresponding vehicle; a bumper middle clamping block is provided in the middle of the fixed frame, the bumper middle clamping block is vertically mounted and can be adjusted horizontally, inserted into the middle of the bumper and abutting against the bumper; an upper bumper clamping block is provided at the upper part of the fixed frame, the upper bumper clamping block is horizontally mounted and matches the upper part of the vehicle's front bumper for clamping.
[0008] Furthermore, the vehicle body positioning clamping assembly is disposed on the upper part of the front bumper positioning clamping assembly, including a positioning frame fixed on a support rod, a horizontal positioning pin and a vertical positioning pin disposed in the middle of the positioning frame, which respectively match the positioning holes on the vertical and horizontal positions of the vehicle body; an upper body clamping block is disposed on the upper part of the positioning frame, the upper body clamping block is horizontally disposed, matches the upper part of the vehicle body, and can clamp.
[0009] Furthermore, the bottom support block, the middle clamping block, the upper clamping block, and the upper clamping block of the vehicle body are all connected to the support rod through a guide mechanism, allowing the position of the clamping blocks to be adjusted.
[0010] Furthermore, the bottom support block, middle clamping block, upper clamping block, and upper body clamping block of the bumper are all symmetrically arranged and made of rubber.
[0011] Furthermore, the horizontal and vertical positioning pins are symmetrically arranged, with the two horizontal positioning pins employing 4-way positioning and 2-way positioning respectively, and the vertical positioning pins all employing 2-way positioning.
[0012] This invention enables the controllable and adjustable gap between the front bumper and the car body, saving time on adjusting the dimensions of various parts, shortening the project development cycle, and ensuring customer quality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1 As shown, a car front bumper positioning device is provided. The device is provided with a base 1, a support rod 2 and a positioning clamping assembly. The base is provided with four movable wheels, and the movable wheels are provided with a braking device. The support rod 2 is fixed on the base 1, and the positioning clamping assembly is provided on the support rod. The positioning clamping assembly includes a body positioning clamping assembly and a front bumper body positioning clamping assembly arranged vertically.
[0026] The front bumper positioning and clamping assembly includes a fixed frame fixedly mounted on a support rod. A bumper bottom support block 3 is provided at the lower part of the fixed frame. The bumper bottom support block is inclined, and its inclination angle is adjustable to match the front bumper of the corresponding vehicle. A bumper middle clamping block 4 is provided in the middle of the fixed frame. The bumper middle clamping block is vertically positioned and can be adjusted horizontally, inserting into the middle of the bumper and abutting against it. An upper bumper clamping block 5 is provided at the upper part of the fixed frame. The upper bumper clamping block is horizontally positioned and matches the upper part of the front bumper of the vehicle for clamping.
[0027] The vehicle body positioning clamping assembly is located on the upper part of the front bumper positioning clamping assembly, including a positioning frame fixed on a support rod. Horizontal positioning pins 6 and 7 and a vertical positioning pin 9 are provided in the middle of the positioning frame, respectively matching the positioning holes on the vertical and horizontal positions of the vehicle body. An upper body clamping block 8 is provided on the upper part of the positioning frame. The upper body clamping block is horizontally positioned and matches the upper part of the vehicle body for clamping.
[0028] The bottom bumper support block 3, the middle bumper clamping block 4, the upper bumper clamping block 5, and the upper body clamping block 8 are all connected to the support rod via a guide mechanism, allowing for adjustment of the clamping block positions. The bottom bumper support block 3, the middle bumper clamping block 4, the upper bumper clamping block 5, and the upper body clamping block 8 are all symmetrically arranged and made of rubber.
[0029] The horizontal and vertical positioning pins are symmetrically arranged. The two horizontal positioning pins adopt 4-way positioning and 2-way positioning respectively, and the vertical positioning pins all adopt 2-way positioning.
[0030] like Figure 2-3 As shown, the device first clamps the car bumper, fixing the front bumper to the device to secure it in the XYZ directions. Then, the device holding the bumper is moved to the front of the vehicle body, aligning it with the positioning holes on the vehicle body to achieve XZ-direction positioning. After positioning, subsequent tightening operations are performed.
[0031] like Figure 4-6 As shown, the device is positioned and clamped to the front bumper of the car by three components: the bottom support block 3, the middle clamping block 4, and the upper clamping block 5. The bottom support block 3 is set at an inclined angle to support the bottom; the middle clamping block 4 holds the bumper in the middle, and the upper clamping block 5 clamps the top securely.
[0032] like Figure 7-9 As shown, the device positions and clamps the vehicle body. Horizontal positioning pins 6 and 7 position the vehicle body in the Z and Y directions, respectively (four-way and two-way positioning). Vertical positioning pin 9 positions the vehicle body in the X direction. The entire vehicle body is then positioned using the upper clamping block 8. After all positioning adjustments are confirmed, the device is finally tightened.
[0033] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
