Description

Technical Field

[0001] The utility model relates to the technical field of composite plate production, in particular to an impact device for strength detection of composite plates for vehicles. Background Art

[0002] In order to meet the quality inspection requirements, automotive composite panels need to be sampled. The sampled panels need to be impact tested to detect the strength of the panels. Generally, the panels are placed under the punching machine, and the two ends of the panels are fixed. The bottom of the middle part of the panel is not supported. The output end of the punching machine punches the panel until it breaks and records the resistance during punching to determine whether the panel meets the strength requirements.

[0003] A pressure plate is needed to fix the plate. Both ends of the plate need to be fixed, and the pressure plate is tightened with bolts. The application range of composite plates is wide, and different usage scenarios require composite plates of different sizes and thicknesses. Therefore, the thickness of the plate to be tested is not fixed. Each time the thickness of the plate needs to be measured, the data needs to be input into the punching machine to adjust the punching force, which reduces the work efficiency of the stamping experiment. Utility Model Content

[0004] The purpose of this application is to provide an impact device for testing the strength of a composite panel for a vehicle, so as to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, the outer walls of the plurality of counterweights facing the movable plate are each provided with a hole, wherein a light sensor is installed in the hole, and the light sensor is connected to the external impact component via an electrical signal. Magnetic plates are fixedly installed on the outer walls of the support platform on both sides away from the movable plate, and the counterweight is installed between the two magnetic plates, with the outer walls on both sides adsorbed to the magnetic plates.

[0009] The beneficial effects of the utility model are as follows: by providing a counterweight block and a movable plate, the push plate pushes the plate, and the spikes on the counterweight block utilize the inertia of the plate to pierce the end of the plate, thereby quickly fixing the plate.

[0014] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0015] like Figure 1-3 The impact device shown in the figure is used for testing the strength of automotive composite panels, including a slide 1 and a support platform 3. The support platform 3 is installed on one side of the slide 1. A movable plate 2 is movably installed between the support platform 3 and the slide 1. A plurality of counterweights 4 are installed on the side of the support platform 3 away from the movable plate 2. The plurality of counterweights 4 are stacked. A plurality of spikes 10 are fixedly installed on the outer wall of the counterweight 4 facing the movable plate 2. The counterweight 4 is made of iron metal. The surfaces of the slide 1, the movable plate 2 and the support platform 3 are coated with an anti-static coating. An impact component is installed directly above the movable plate 2.

[0016] Cylinders 1 (5) are installed on both sides of the bottom of the movable plate 2. One cylinder 1 (5) is fixedly mounted on the bottom of the slide 1, and the other cylinder 1 (5) is fixedly mounted on the bottom of the support platform 3. The output ends of both cylinders 1 (5) are fixedly connected to one side of the movable plate 2. Cylinder 2 (6) is fixedly mounted on the side of the bottom of the slide 1 away from the movable plate 2. A push plate 7 is installed on the outside of one end of the slide 1, and the output end of cylinder 2 (6) is fixedly connected to the push plate 7.

[0017] The counterweights 4 have holes on their outer walls facing the movable plate 2. Light sensors 8 are installed in these holes and are electrically connected to the external impact assembly. Magnetic plates 9 are fixedly mounted on the outer walls of the support platform 3, facing away from the movable plate 2. The counterweights 4 are mounted between these two magnetic plates 9, with the outer walls on both sides adsorbed to the plates.

[0018] Example: Place the composite plate that needs to be impact tested on the slide 1. There is a certain distance between the push plate 7 and the end of the slide 1. Fit the end of the plate to the outer wall of the push plate 7. Then the operator starts the cylinder 2 6. The cylinder 2 6 recycles the output end to drive the push plate 7 to move. The push plate 7 quickly pushes the plate. When the push plate 7 moves to the end of the slide 1, it will hit the end. After the push plate 7 hits the end of the slide 1, the push plate 7 stops. The plate will continue to slide due to inertia. After passing the moving plate 2, the end of the plate will hit the spike 10 on the counterweight 4, so that the plate is fixed. The application range of composite plates is relatively wide. Different usage scenarios require composite plates of different sizes and thicknesses. Therefore, the thickness of the plates for impact tests on the slide 1 and the support platform 3 is not consistent. If the thickness is inconsistent, the force of the stamping assembly to stamp the plate also needs to be adjusted. Therefore, once the sheet material is secured by the detector on the counterweight 4, it will also block the light sensors 8 on the outer wall of the counterweight 4. When the counterweights 4 are stacked, the control terminal of the stamping assembly can determine the sheet material's thickness range based on the number of blocked light sensors 8. The punching force of the stamping assembly can then be adjusted. The counterweight 4 is fixed by magnetic plates 9, making it easy to assemble and disassemble.

[0019] After the plate is fixed by the spikes 10, the cylinder 15 drives the movable plate 2 forward, separating it from the slide 1 and the support 3, making the bottom of the plate at the position of the movable plate 2 hollow. After the punching machine adjusts the punching force, it punches the plate. The output end of the punching machine will impact the plate until it breaks and record the resistance during the punching to determine whether the plate strength is qualified. After the plate is punched and broken, the movable plate 2 is driven by the cylinder 15 to reset and move between the slide 1 and the support 3. At the same time, the broken plate between the slide 1 and the support 3 will be pushed by the movable plate 2 and fall to the bottom of the movable plate 2. It plays the role of automatically recovering the plate.

[0020] It should be noted that the parts not covered in the present invention are the same as the existing technology or can be implemented by using the existing technology; the various drives in the present invention can be implemented by using corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structure in the drawings.

[0021] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
