Technical Field

[0001] This utility model relates to the field of impact resistance testing technology, specifically to an impact resistance testing device for automotive exterior parts. Background Technology

[0002] Automotive exterior parts are external components that are bolted or clipped to the vehicle body, serving both decorative and protective functions. They primarily include front and rear bumpers and grilles. Automotive interior and exterior parts are typically made of non-metallic materials, with plastics being the most widely used. After production, automotive exterior parts usually undergo impact testing to ensure manufacturing quality, which requires the use of impact testing equipment.

[0003] For example, an impact testing device according to Chinese patent application number CN202321713020.4 can be used to perform impact testing on automotive exterior parts. The device includes a base, a bracket fixedly connected to the base, a support rod fixedly connected to the bracket, a rotating rod rotatably connected to the support rod, an impact hammer mounted on one end of the rotating rod, a placement plate fixedly connected to the base, two fixed seats fixedly connected to the placement plate, a fixing groove formed in the fixing seat, both ends of the fixing groove communicating with the outside, and a locking mechanism for locking the parts in the fixing groove on the fixing seat. This invention has the advantage of facilitating the operator's fixation of the workpiece.

[0004] However, in actual use, the position of the impact hammer of the above-mentioned device is fixed, and the car exterior parts are also locked in the fixed groove. Therefore, it is impossible to perform impact resistance testing on different parts of the car exterior parts, which has limitations. Utility Model Content

By moving a U-shaped moving plate horizontally along a slot, an electric push rod drives a stamping plate to rise and fall, thereby enabling impact resistance testing at any location on the automotive exterior parts. This improves the impact resistance testing effect and achieves comprehensive testing, effectively solving the problems in the background technology.

The piston rod of the electric push rod passes through the U-shaped moving plate and is fixedly connected to the top of the stamping plate, so that the electric push rod can drive the stamping plate to descend and perform anti-stamping test on the automotive exterior parts.

[0011] Preferably, a limiting rod is fixed between the two ends inside the other slot, and the front end of the U-shaped moving plate is slidably sleeved on the limiting rod to facilitate limiting the movement of the U-shaped moving plate.

[0012] Preferably, a motor is fixedly installed inside one end of the U-shaped support frame on the rear side, and the output shaft of the motor passes through the rear slot and is fixedly connected to one end of the threaded rod, so as to facilitate the motor to drive the threaded rod to rotate.

[0013] Preferably, the fixing component includes an L-shaped support frame, which is fixedly disposed at the center of one side of the top of the testing platform, and a lifting rod is provided through the top of the L-shaped support frame.

[0014] Preferably, a Z-shaped fixing frame is fixedly provided at the bottom end of the lifting rod, and one end of the Z-shaped fixing frame is in contact with the L-shaped support frame.

The main support plate on the front side is fixedly provided with a control panel for controlling the electric push rod and motor to work. The four corners of the bottom of the testing platform are fixedly provided with casters to facilitate the movement of this utility model.

[0016] Compared with the prior art, this utility model provides an impact resistance testing device for automotive exterior parts, which has the following beneficial effects:

[0017] 1. This utility model uses a U-shaped moving plate to move horizontally along the slot, while simultaneously driving the front end of the slot to slide horizontally along the limiting rod to limit the movement of the U-shaped moving plate. After moving to the appropriate position, the control panel is operated to control the electric push rod to drive the stamping plate to rise and fall, thereby realizing the anti-stamping test on any position on the automotive exterior parts, improving the anti-stamping test effect and achieving comprehensive testing.

The four corners of the bottom of the testing platform 1 are fixedly provided with moving wheels 9 to facilitate the movement of this utility model.

[0027] like Figure 1 , 2 As shown in Figure 4, fixing components 6 are fixedly provided on both the front and rear sides of the top of the testing platform 1 for clamping and fixing automotive exterior parts of different sizes. The fixing components 6 include an L-shaped support frame 61, which is fixedly located at the center of one side of the top of the testing platform 1. A lifting rod 64 is provided through the top of the L-shaped support frame 61. A Z-shaped fixing frame 63 is fixedly provided at the bottom of the lifting rod 64, and one end of the Z-shaped fixing frame 63 is in contact with the L-shaped support frame 61. A spring 62 is sleeved on the lifting rod 64, and both ends of the spring 62 are in contact with the top of the inside of the L-shaped support frame 61 and the top of the Z-shaped fixing frame 63, respectively, to facilitate lifting the Z-shaped fixing frame 63 to compress the spring 62.

[0028] By setting the fixing component 6, the automotive exterior parts that need to be tested for impact resistance are first picked up. Then, the Z-shaped fixing bracket 63 is manually moved, causing it to rise along the lifting rod 64 and against the L-shaped support bracket 61, while compressing the spring 62. The automotive exterior parts are then placed at the bottom of the two Z-shaped fixing brackets 63. After the operator releases the grip, the Z-shaped fixing bracket 63 will press and fix the top of the automotive exterior parts of different sizes along the lifting rod 64 under the elastic action of the spring 62, thereby ensuring the stability of the subsequent impact resistance test of the automotive exterior parts and improving the test quality.

[0029] like Figure 1-3As shown, a moving detection component 7 is provided between the two U-shaped support frames 2 for driving the stamping plate 4 to move, facilitating impact resistance testing at any position on the automotive exterior parts. The moving detection component 7 includes a U-shaped moving plate 73. Both U-shaped support frames 2 have slots 3 inside. The two ends of the U-shaped moving plate 73 are respectively located inside the two slots 3. A threaded rod 71 is connected between the two ends of one slot 3 via a bearing. The rear end of the U-shaped moving plate 73 is threadedly connected to the threaded rod 71. An electric push rod 5 is fixedly provided at the top of the U-shaped moving plate 73.

[0030] A limiting rod 72 is fixedly provided between the two ends of the other slot 3. The front end of the U-shaped moving plate 73 is slidably sleeved on the limiting rod 72 to limit the movement of the U-shaped moving plate 73. A motor 74 is fixedly provided inside one end of the rear U-shaped support frame 2. The output shaft of the motor 74 passes through the rear slot 3 and is fixedly connected to one end of the threaded rod 71 to facilitate the motor 74 driving the threaded rod 71 to rotate. A control panel 8 for controlling the operation of the electric push rod 5 and the motor 74 is fixedly provided on the front main support plate 11.

[0031] After the automotive exterior parts are clamped and fixed by the moving detection component 7, the control panel 8 controls the motor 74 in the drive slot to work. The motor 74 drives the threaded rod 71 inside the slot 3 to rotate. At the same time, the rotation of the threaded rod 71 drives the U-shaped moving plate 73 to move horizontally along the slot 3, and at the same time drives the front end of the slot 3 to slide horizontally along the limiting rod 72 to limit the movement of the U-shaped moving plate 73. After moving to the appropriate position, the control panel 8 controls the electric push rod 5 to drive the stamping plate 4 to rise and fall, thereby realizing the impact resistance test on any position on the automotive exterior parts, improving the impact resistance test effect and realizing comprehensive testing.
