[0001] The utility model belongs to the technical field of automobile parts processing, and particularly relates to an automatic punching device for an automobile front bumper. Background Technique
[0002] An automobile bumper is a safety device that absorbs and mitigates external impact forces 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, with a relatively large gap from the vehicle body, looking very unsightly. At the same time, the automobile bumper is located in most areas in front of and behind 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 injury of passengers and drivers during high-speed collisions. Now, more and more are designed for pedestrian protection. In order to facilitate the installation of the bumper, punching treatment needs to be carried out on the bumper, and thus corresponding punching devices will be used.
[0003] However, when the existing punching device punches the bumper, due to the lack of the function of positioning and clamping the bumper, during the punching process, the position of the bumper cannot be guaranteed to be stable. Therefore, the bumper is prone to deflection during the punching process. At the same time, it does not have the function of adjusting the punching position, so it will affect the comprehensiveness of punching the bumper. For this reason, we provide an automatic punching device for an automobile front bumper to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide an automatic punching device for an automobile front bumper, which clamps the bumper through two positioning clamping plates to ensure the stability of the bumper during the punching process. At the same time, the movement of the lifting cylinder driven by the lead screw can punch the bumper at multiple points, improving the comprehensiveness of punching.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.
[0028] Embodiment 1, please refer toFigures 1 to 6 , the utility model is an automatic punching device for the front bumper of an automobile. The bumper is clamped by two positioning clamping plates 301 to ensure the stability of the bumper during the punching process. At the same time, the lead screw 4 drives the movement of the lifting cylinder 5, and multiple points of punching can be performed on the bumper to improve the comprehensiveness of punching.
[0029] Specifically, there is a frame 1; a processing block 2 is arranged on the bottom surface inside the frame 1. A notch 201 is opened on the upper end surface of the processing block 2. Strip-shaped plates 3 are arranged on the front and rear end surfaces of the processing block 2. Positioning clamping plates 301 are fixed at the left and right parts of the upper end surface of the strip-shaped plate 3. A lifting cylinder 5 is arranged inside the frame 1 directly above the processing block 2. A punching rod 501 is fixed at the piston end of the lifting cylinder 5. A lead screw 4 is rotatably arranged inside the frame 1 behind the lifting cylinder 5. A motor 6 fixedly connected to the left end surface of the lead screw 4 is fixed at the left end of the frame 1. A ball seat 401 is sleeved on the periphery of the lead screw 4. A moving ring block 502 rotatably arranged on the ball seat 401 is fixed at the rear end surface of the lifting cylinder 5.
[0030] The operation process of this embodiment is as follows: Through the setting and use of the above structure, when punching the front bumper of an automobile is required, the two positioning clamping plates 301 are moved in opposite directions to the processing block 2, so that the distance length between the two positioning clamping plates 301 can be adjusted. At this time, the bumper is arranged at the upper end surface position of the processing block 2 between the two positioning clamping plates 301, and then the positioning clamping plates 301 are loosened. Then the two positioning clamping plates 301 will retract relatively, so that the positioning clamping plates 301 clamp the bumper at the upper end surface position of the processing block 2 to ensure the stability of punching. At the same time, when punching the bumper, the motor 6 is controlled to work. Thus, the motor 6 will directly drive the lead screw 4 to rotate, and then the lead screw 4 will move the lifting cylinder 5, so that the lifting cylinder 5 will drive the punching rod 501 to move in the left and right directions. Therefore, when punching, the lifting cylinder 5 will push the punching rod 501 to punch the bumper, and at the same time, the movement of the lifting cylinder 5 can improve the comprehensiveness of punching.
[0031] Furthermore, a ring groove 504 is opened in the middle of the inner side of the moving ring block 502. A ring plate 402 rotatably arranged inside the ring groove 504 is fixed on the periphery of the ball seat 401. When the lead screw 4 drives the ball seat 401 to move, the ball seat 401 will drive the ring plate 402 to rotate and move inside the ring groove 504, and the ring plate 402 will drive the moving ring block 502 to move, thereby driving the lifting cylinder 5 to move.
[0032] Further, a limiting rod 105 is fixed between the left and right side surfaces inside the frame 1 above the lead screw 4. A limiting ring block 503 sleeved on the limiting rod 105 is fixed to the rear end surface of the lifting cylinder 5. A strip-shaped opening 101 is formed in the upper end surface of the frame 1, and the upper end surface of the lifting cylinder 5 is located in the strip-shaped opening 101. When the lifting cylinder 5 moves inside the frame 1, the lifting cylinder 5 will drive the limiting ring block 503 to slide on the limiting rod 105. At the same time, the limiting rod 105 will limit the limiting ring block 503 to ensure that the lifting cylinder 5 can stably slide inside the frame 1.
[0033] Example 2, please refer to Figure 2 and Figure 6 , on the basis of Example 1, by the operation of the transverse cylinder 104, the processing block 2 is moved in the front-back direction, so as to control the bumper to slide in the front-back direction.
[0034] Specifically, square plates 102 are fixed to the lower parts of the front and rear sides of the frame 1. Positioning rods 103 are fixed to the left and right parts between the two square plates 102. The transverse cylinder 104 is fixed to the rear end surface of the square plate 102 behind the frame 1, and the piston end of the transverse cylinder 104 is fixedly connected to the rear end surface of the processing block 2. The end surface of the processing block 2 is sleeved on the positioning rod 103 through a positioning hole 204 formed therethrough.
[0035] The operation process of this embodiment is as follows: when it is necessary to control the front and rear positions of the bumper, the transverse cylinder 104 can be controlled to work. Then, the transverse cylinder 104 will push the processing block 2 to slide in the front-back direction inside the frame 1. At the same time, the positioning rod 103 is located in the positioning hole 204 to limit the processing block 2 and ensure that the processing block 2 stably slides inside the frame 1.
[0036] Example 3, please refer to Figure 1 , Figure 4 and Figure 6 , on the basis of Example 1, by the pushing of the spring 303 on the circular plate 304, it is ensured that the positioning clamping plate 301 stably clamps the bumper.
[0037] Specifically, two symmetrically arranged moving holes 203 are formed inside the processing block 2. Stopping holes 202 communicating with the inside of the moving holes 203 are formed in the front and rear end surfaces of the processing block 2. Moving rods 302 slidably passing through the inside of the stopping holes 202 are fixed to the end surfaces of the strip-shaped plate 3 opposite to the end surface of the processing block 2. Circular plates 304 slidably located inside the moving holes 203 are fixed to the other end surfaces of the moving rods 302. Springs 303 sleeved on the moving rods 302 are fixed to the opposite end surfaces of the two circular plates 304 in the front-back direction, and one end of each spring 303 abuts against the inner end surface of the moving hole 203.
[0038] The operation process of this embodiment is as follows: Move the strip plate 3 in the direction opposite to the processing block 2. The strip plate 3 will drive the moving rod 302 to slide in the blocking hole 202, and thereby drive the circular plate 304 to move inside the moving hole 203. Furthermore, the circular plate 304 will compress the spring 303. Therefore, after the bumper is positioned between the two positioning clamping plates 301 at the front and rear, the strip plate 3 can be released at this time. Then, the spring 303 will push the circular plate 304 to move back to its original position, thereby driving the positioning clamping plate 301 to clamp the bumper.
