Description

Technical Field

[0001] The utility model relates to the technical field of detection tooling, in particular to an EPP bumper detection tooling. Background Art

[0002] Bumpers are installed at the front and rear ends of the car. They not only have decorative functions, but more importantly, they are safety devices that absorb and mitigate external impact, protect the car body and protect the safety of the passengers. Existing bumpers generally add EPP material bumper foam inside to fill the bumper to enhance its impact resistance and absorption capacity. EPP material bumpers need to be tested before leaving the factory.

[0003] In order to facilitate the inspection of EPP material automobile bumpers, the existing technology has made many improvements to the EPP bumper inspection tooling. For example, the patent publication number CN213986042U discloses an EPP bumper mechanical strength inspection tooling, including a detection base plate, a detection slope and a bumper. A fastening slide is provided on the top of the detection base plate. A fastening screw is rotated at the center of the two ends of the fastening slide. Two sets of fastening sliders are slid inside the fastening slide. The fastening screw thread passes through the fastening slider and the end rotates through the detection base plate. The fastening screw end A knob is fixed on the top, a fastening plate is fixed on the top center of the fastening slider, a track groove is cooperatively arranged on the detection bottom plate and the detection slope surface, a partition is fixed on the center of the track groove, and a roller groove is opened at the bottom center of the two groups of areas of the track groove separated by the partition, and a roller is arranged inside the roller groove. Through the above method, the utility model can use the knob to drive the fastening screw to rotate, and under the cooperation of the fastening screw and the two groups of fastening sliders with opposite rotation directions, the two groups of fastening sliders are driven to move toward each other, so that the two groups of fastening plates are fixed to the two sides of the bumper to achieve the positioning of the bumper.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, the bumper is impacted by falling an impact plate, thereby realizing the impact detection of the bumper. However, in reality, after the bumper is installed on the car, its exposed positions are likely to be hit. When the bumper is impact-tested in the above-mentioned comparative documents, the impact detection can only be performed on one position of the bumper, thereby reducing the accuracy of the detection result. Therefore, there is an urgent need in this field to improve the EPP bumper detection tooling to solve the defects of the existing technology. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example: See attached Figures 1 to 5 , This embodiment provides an EPP bumper testing tool, including a testing platform 1 and a bumper body 2 to be tested placed on the testing platform 1, two symmetrical clamping plates 3 are provided on the upper surface of the testing platform 1, and a first driving unit 4 for driving the two clamping plates 3 to move toward or away from each other is provided on one side of the testing platform 1, an inverted U-shaped moving frame 5 is provided between the opposite sides of the testing platform 1, a second driving unit 6 for driving the moving frame 5 to move along the testing platform 1 is provided on the opposite side of the testing platform 1, a telescopic device 7 is provided on the top of the moving frame 5, and a third driving unit 8 for driving the telescopic device 7 to move along the moving frame 5 is provided on the side of the moving frame 5, an electric-controlled magnet seat 9 is fixedly installed on the telescopic lower end of the telescopic device 7, and an impact member 10 for performing impact detection on the bumper body 2 is magnetically attracted on the lower surface of the electric-controlled magnet seat 9, an end limiting unit 11 for limiting the two ends of the bumper body 2 is provided between the clamping plate 3 and the testing platform 1, and a main controller 12 for controlling the overall device is fixedly installed on the side of the moving frame 5.

[0027] Specifically, when it is necessary to perform an impact test on the bumper body 2 with EPP material added, the bumper body 2 is placed near the middle position on the test platform 1, and the first drive unit 4 is started by the main controller 12. The first drive unit 4 drives the two clamping plates 3 to move relative to each other. When the clamping plates 3 move, the end limit units 11 are driven to push the bumper body 2 to move. The cooperation of the two clamping plates 3 and the end limit units 11 pushes the bumper body 2 to the middle position of the test platform 1 and limits its position. There is no need to clamp it. As long as the bumper body 2 can be limited, the second drive unit 6 is started by the main controller 12. The second drive unit 6 drives the mobile frame 5 to move along the test platform 1 and drives the mobile frame 5 to a position where the bumper body 2 is adapted. By controlling the third drive unit 8, the telescopic device 7 can be driven to move along the inner top wall of the mobile frame 5. The position of the telescopic device 7 is adjusted according to the required impact detection position of the bumper body 2. After the position of the telescopic device 7 is adjusted, the telescopic lower end of the telescopic device 7 moves downward, the electric-controlled magnetic seat 9 is opened, and the impact member 10 is adsorbed on the lower surface of the electric-controlled magnetic seat 9. The impact member 10 of appropriate weight is selected according to the impact force required for the detection. At the same time, the starting height of the impact member 10 is controlled by telescopic control of the telescopic device 7 according to the impact force required for detection. After the adjustment is completed, the electric-controlled magnetic seat 9 is closed, and the impact member 10 falls freely to perform impact detection on the bumper body 2. At the same time, the two clamping plates 3 and the movable frame 5 play a protective effect to prevent the impact member 10 from rolling down. Through the above-mentioned settings, bumper bodies 2 of different sizes can be impact detected, and the position and impact force of the impact detection of the bumper body 2 can be adjusted to improve the accuracy of the detection results of the impact detection of the bumper body 2.

[0028] The first driving unit 4 includes a first driving motor 13 fixedly mounted on one side of the detection platform 1, and the lower sides of the two clamping plates 3 are fixedly connected to the first sliding blocks 14. The upper surface of the detection platform 1 is provided with a first sliding groove 15 adapted to the first sliding block 14. The first sliding groove 15 is rotatably connected to a bidirectional screw rod 16 with one end fixedly mounted on the output end of the first driving motor 13. The bidirectional screw rod 16 passes through the two first sliding blocks 14 and is threadedly connected to the first sliding block 14.

[0029] Specifically, when the first drive motor 13 is started, the output end of the first drive motor 13 drives the bidirectional screw 16 to rotate. The threads on the side of the bidirectional screw 16 are symmetrical and in opposite directions. When the bidirectional screw 16 rotates, it drives the two first sliding blocks 14 to slide toward or away from each other in the first sliding groove 15, and then the two first sliding blocks 14 drive the corresponding clamping plates 3 to move toward or away from each other.

[0030] The second drive unit 6 includes two second drive motors 17 fixedly mounted on the sides of the detection platform 1, and second sliding blocks 18 are fixedly mounted on the sides of both ends of the mobile frame 5. Second sliding grooves 19 adapted to the second sliding blocks 18 are opened on the opposite sides of the detection platform 1. A first screw rod 20 with one end fixedly mounted on the output end of the second drive motor 17 is rotatably connected in the second sliding groove 19. The first screw rod 20 passes through the second sliding block 18 and is threadedly connected to the second sliding block 18.

[0031] Specifically, the two second drive motors 17 are synchronous motors. When the second drive motors 17 are started, the output end of the second drive motor 17 drives the first screw rod 20 to rotate. When the first screw rod 20 rotates, it drives the second sliding block 18 to slide in the second sliding groove 19. The two second sliding blocks 18 drive the movable frame 5 to slide along the side of the detection platform 1.

[0032] The third driving unit 8 includes a third driving motor 21 fixedly mounted on one side of the mobile frame 5, a third sliding block 22 fixedly mounted on the upper end of the telescopic device 7, a third sliding groove 23 adapted to the third sliding block 22 is opened on the inner top wall of the mobile frame 5, and a second screw rod 24 with one end fixedly mounted on the output end of the third driving motor 21 is rotatably connected in the third sliding groove 23, and the second screw rod 24 passes through the third sliding block 22 and is threadedly connected to the third sliding block 22.

[0033] Specifically, when the third drive motor 21 is started, the output end of the third drive motor 21 drives the second screw rod 24 to rotate. When the second screw rod 24 rotates, it drives the third sliding block 22 to slide in the third sliding groove 23. When the third sliding block 22 moves, it drives the telescopic device 7 to move along the inner top wall of the movable frame 5.

[0034] The end limit unit 11 includes two symmetrical fixed blocks 25 arranged on the upper surface of the detection platform 1, and a moving column 26 is passed through the two fixed blocks 25. The opposite ends of the two moving columns 26 are fixedly connected with a clamping plate 27. A spring 29 is fixedly connected between the clamping plate 27 and the fixed block 25 and is sleeved on the side of the moving column 26. A wedge plate 30 is provided on the side of a clamping plate 3, and the side surface is adapted to the end of the moving column 26.

[0035] Specifically, when the two clamping plates 3 move relative to each other, the inclined surface of the wedge plate 30 squeezes the moving column 26, and the two moving columns 26 move toward each other at the same time. At this time, the spring 29 is stretched, and the moving column 26 drives the elastic clamping plate 27 to push the end of the bumper body 2 toward the center position of the test platform 1 and limit it. When the two clamping plates 3 move away from each other, due to the contraction of the spring 29, the two clamping plates 27 return to the starting position, which facilitates the centering and limiting of the bumper body 2.

[0036] A fourth sliding block 31 is fixedly connected to the lower side of the fixed block 25, a fourth sliding groove 32 adapted to the fourth sliding block 31 is provided on the upper surface of the detection platform 1, and a first opening groove 34 is provided on the side of the detection platform 1. A first adjusting rod 33 with one end extending into the first opening groove 34 is rotatably connected in the fourth sliding groove 32, the first adjusting rod 33 passes through the fourth sliding block 31 and is threadedly connected to the fourth sliding block 31, and a first limiting nut 35 is threadedly connected to the side of one end of the first adjusting rod 33 located in the first opening groove 34.

[0037] Specifically, when impact detection is required for bumper bodies 2 of different sizes, the position of the fixed block 25 needs to be adjusted. When the position of the fixed block 25 needs to be adjusted, the first adjusting rod 33 is rotated. When the first adjusting rod 33 rotates, the fourth sliding block 31 is driven to slide in the fourth sliding groove 32. The fourth sliding block 31 drives the fixed block 25 to move. When the fixed block 25 moves to the appropriate position, the first limiting nut 35 is tightened to limit and fix the position of the first adjusting rod 33, thereby improving the applicability of the overall device.

[0038] A fifth sliding block 36 is fixedly connected to one end of the wedge plate 30, a fifth sliding groove 37 adapted to the fifth sliding block 36 is opened on the side of a clamping plate 3, a second opening groove 39 is opened at one end of a clamping plate 3, a second adjusting rod 38 with one end extending into the second opening groove 39 is rotatably connected in the fifth sliding groove 37, the second adjusting rod 38 passes through the fifth sliding block 36 and is threadedly connected to the fifth sliding block 36, and a second limiting nut 40 is threadedly connected to the side of one end of the second adjusting rod 38 located in the second opening groove 39.

[0039] Specifically, when it is necessary to perform impact detection on bumper bodies 2 of different sizes, the position of the wedge plate 30 needs to be adjusted to a position that is compatible with the fixed block 25 and the movable column 26. When the position of the wedge plate 30 needs to be adjusted, the second adjusting rod 38 is rotated. When the second adjusting rod 38 rotates, the fifth sliding block 36 is driven to slide in the fifth sliding groove 37. The fifth sliding block 36 drives the wedge plate 30 to move along the clamping plate 3. After the position of the wedge plate 30 is adjusted to a suitable position, the second limit nut 40 is tightened to limit the position of the second adjusting rod 38, thereby improving the applicability of the overall device.
