[0002] An automobile bumper is a safety device that absorbs and reduces the impact force from the outside world and protects the front and rear parts of the vehicle body. Many years ago, the front and rear bumpers of automobiles were made of steel plates stamped into channel steel, riveted or welded to the longitudinal beams of the vehicle frame, and there was a relatively large gap with the vehicle body, looking very unsightly. At the same time, the automobile bumper is located in most areas in the front and rear of the vehicle, and is designed on the surface to avoid the impact of external damage to the vehicle on the vehicle safety system. They have the ability to reduce the injuries of the driver and passengers during a high-speed collision. Now, more and more are designed for pedestrian protection. Therefore, when assembling the bumper, a corresponding positioning device is required.

[0003] However, when the existing positioning device is in use, since it does not have the function of synchronously clamping the bumper, the clamping efficiency will be affected, so that the bumper cannot be quickly positioned and assembled. At the same time, since the positioning device does not have the function of height adjustment, it does not have the ability to adjust the clamping height of the bumper according to the height of the vehicle, which will affect the general use of the positioning device. For this reason, we provide a positioning device for assembling an automobile front bumper to solve the above problems. Summary of the Utility Model

Detailed Description of the Preferred Embodiments

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0029] Embodiment 1. Please refer to Figures 1 to 7 , the present utility model is a positioning device for assembling the front bumper of an automobile. By synchronously driving two clamping plates 4 to move through an adjusting plate 3, rapid positioning of the bumper is achieved. At the same time, a lifting column 203 moves along the inside of a telescopic ring column 5 to adjust the height of a stroke frame 2.

[0030] Specifically, a bottom plate 1; a stroke frame 2 is arranged directly above the bottom plate 1. Two symmetrically arranged clamping plates 4 are arranged on the left part of the stroke frame 2. Two vertically symmetrically arranged stroke openings 201 are formed through the side surface of the stroke frame 2 corresponding to the clamping plates 4. A circular opening 204 is formed inside the stroke frame 2 between the two stroke openings 201. An adjusting plate 3 is arranged at the position corresponding to the circular opening 204 on the right side of the stroke opening 201. A toothed plate 6 rotating inside the circular opening 204 is arranged on the left side of the adjusting plate 3. Slide plates 401 respectively arranged in a staggered manner inside the stroke openings 201 are fixed to the right end faces of the clamping plates 4. Rack bars 403 sliding inside the stroke openings 201 are fixed to the opposite end faces of the two slide plates 401, and the rack bars 403 are engaged with the toothed plate 6. Telescopic ring columns 5 are arranged at the front and rear parts between the stroke frame 2 and the bottom plate 1. Two lifting columns 203 respectively sliding and inserted inside the telescopic ring columns 5 are fixed to the lower end face of the stroke frame 2.

[0031] The operation process of this embodiment is as follows: Through the setting and use of the above structure, when installing the front bumper of an automobile, the bumper is arranged between the two clamping plates 4, and the adjusting plate 3 is rotated. Thus, the adjusting plate 3 can drive the two rack bars 403 to move relatively through the toothed plate 6, controlling the two clamping plates 4 to clamp the bumper. In this way, when installing the bumper, the situation of hand shaking during the process will not occur. At the same time, when adjusting the clamping height of the bumper, by controlling the lifting column 203 to move upward along the inside of the telescopic ring column 5, the lifting column 203 will drive the stroke frame 2 to move upward. And with the coordinated use of the stroke frame 2 and the clamping plates 4, the stroke frame 2 will drive the bumper to move upward through the clamping plates 4, thereby realizing the adjustment of the assembly height of the bumper.

[0032] Further, square openings 202 are provided at both front and rear ends of the stroke frame 2 corresponding to the positions of the stroke openings 201. The shape of the square openings 202 is the same as the shape and size of the end face of the rack 403. Positioning plates 402 are fixed to the end faces of the slide plate 401 passing through the stroke openings 201. A metal ring 206 is fixed to the right end face of the stroke frame 2, and a magnetic ring 301 adsorbed to the metal ring 206 is fixed to the left end face of the adjusting plate 3. In order to ensure the stability of the clamping plate 4 after position adjustment, the adjusting plate 3 can be loosened. Thus, the magnetic ring 301 on the adjusting plate 3 will be adsorbed to the metal ring 206, so as to ensure that the adjusting plate 3 and the magnetic plate will not rotate and move randomly, and thus ensure that the two clamping plates 4 will not move relatively or oppositely randomly.

[0033] Example 2. Please refer to Figure 2 and Figure 3 , on the basis of Example 1, the cylinder 504 is used to push the stroke frame 2 to move up and down, so as to realize the automatic lifting of the stroke frame 2.

[0034] Specifically, rail strips 101 are fixed to the upper end face of the bottom plate 1 corresponding to the positions of the telescopic ring columns 5. Sliders 501 slidably clamped on the rail strips 101 are fixed to the lower end faces of the telescopic ring columns 5. A support plate 502 is fixed at the position between the two sliders 501. A cylinder 504 with a piston end fixedly connected to the bottom end of the stroke frame 2 is fixed to the upper end face of the support plate 502. A push rod 503 is fixed at the position between the right end faces of the two telescopic ring columns 5.

[0035] The operation process of this embodiment is as follows: In order to be able to automatically adjust the movement of the stroke frame 2, the cylinder 504 can be controlled to work. Thus, the cylinder 504 will push the stroke frame 2 to move upward, and the stroke frame 2 will drive the lifting column 203 to slide inside the telescopic ring column 5. At the same time, when it is necessary to push the stroke frame 2 to move, the push rod 503 can be directly controlled to move, and the push rod 503 will directly push the telescopic ring column 5 to move. Thus, the telescopic ring column 5 will drive the slider 501 to move along the rail strip 101.

[0036] Example 3. Please refer to Figure 3 , Figure 4 and Figure 5 , on the basis of Example 1, the pull plate 303 is linked with the convex rod 604 through the notch 304, so as to realize the convenient control of the rotation of the toothed plate 6.

[0037] Specifically, rotation holes 205 communicating with the interior of the circular opening 204 are formed in the left and right end faces of the travel frame 2. A rotating rod 601 rotatably positioned inside the rotation hole 205 is fixed in the middle of the toothed plate 6. A limiting hole 603 is formed in the end face of the rotating rod 601 to the right of the toothed plate 6, and a movable hole 602 is formed in the inner end face of the limiting hole 603. A movable rod 302 passing through the interior of the limiting hole 603 is fixed to the left end face of the adjusting plate 3. A pulling plate 303 slidably positioned inside the movable hole 602 is fixed to the end face of the movable rod 302. A spring 305 sleeved on the movable rod 302 is fixed to the end face of the pulling plate 303. Four convex rods 604 arranged in a circumferential and evenly distributed manner are fixed to the inner side surface of the movable hole 602. The pulling plate 303 is sleeved on the convex rods 604 through a notch 304 formed on the circumferential side thereof.

[0038] The operation process of this embodiment is as follows: When the adjusting plate 3 is pulled, the adjusting plate 3 drives the movable rod 302 and the pulling plate 303 to slide inside the movable hole 602 and the limiting hole 603, and the pulling plate 303 compresses the spring 305. Thus, the adjusting plate 3 is disengaged from the end face of the travel frame 2. Therefore, after the adjusting plate 3 is controlled to rotate, since the pulling plate 303 is connected to the convex rod 604 through the notch 304, when the pulling plate 303 is driven by the adjusting plate 3 to rotate, the adjusting plate 3 drives the toothed plate 6 to rotate through the pulling plate 303 and the convex rod 604.
