Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular relates to a beam reinforcement plate resistance strength detector for processing automobile parts. Background Art

[0002] The crossbeam reinforcement plate is a reinforcement component of the automobile crossbeam. It is used to improve the strength and rigidity of the automobile crossbeam, so as to cooperate with the automobile crossbeam to ensure the torsional rigidity of the frame, bear the load, disperse and absorb the impact force when the vehicle is hit, and improve the safety of the vehicle. The resistance strength detection of the crossbeam reinforcement plate is an important project in the production and processing of automobile parts. The existing automobile crossbeam reinforcement plate resistance strength detection device is mainly based on the pressure mechanism to press the crossbeam reinforcement plate from top to bottom to detect the compression resistance of the crossbeam reinforcement plate. For example, the automobile crossbeam reinforcement plate detection device announced as CN217716202U, CN116558967B, etc. are all like this; however, the vehicle safety issue is particularly important when the car is hit. In fact, the direction of the car being hit is usually from the lateral direction around the car body, and it is rare to be squeezed vertically from top to bottom. Therefore, it is necessary to detect the bending strength of the crossbeam reinforcement plate by lateral pressure, which has an important guiding role in studying the safety of the car when it is hit. Summary of the invention

[0003] The purpose of the present invention is to provide a beam reinforcement plate resistance strength detector for automobile parts processing to solve the problem that the existing detection device proposed in the above background technology lacks lateral pressure to detect the bending strength of the beam reinforcement plate.

[0004] The present invention is achieved through the following technical solutions:

[0005] A beam reinforcement plate resistance strength detector for automobile parts processing comprises a detection platform, on the surface of the detection platform are arranged a first support platform, a second support platform and a third support platform spaced from left to right, a clamp for clamping and fixing the left end of the beam reinforcement plate is arranged on the top of the first support platform, the second support platform is used to support the right end of the beam reinforcement plate, and a hydraulic cylinder for applying lateral pressure to the right end of the beam reinforcement plate is arranged on the top of the third support platform, and the right end of the beam reinforcement plate is laterally pressed by the hydraulic cylinder to simulate the lateral force of the beam reinforcement plate when the automobile is subjected to a lateral impact, so as to detect the bending resistance of the beam reinforcement plate;

[0006] A 3D line laser profile sensor for measuring the deformation of the beam reinforcement plate is arranged above the table top of the test bench. When the hydraulic cylinder applies lateral pressure to the beam reinforcement plate, the 3D line laser profile sensor can be used to perform high-precision dimensional measurement and morphological analysis on the beam reinforcement plate after the force is applied. The 3D line laser profile sensor acquires the three-dimensional information of the surface of the beam reinforcement plate by emitting a laser beam and receiving a reflected signal to measure the deformation of the beam reinforcement plate. The 3D line laser profile sensor can capture the slight changes on the surface of the beam reinforcement plate and can evaluate its bending resistance according to the deformation of the beam reinforcement plate after the force is applied.

[0007] An arc-shaped slide groove is provided on the right end surface of the testing bench, and multiple bolts are installed in the arc-shaped slide groove. The third support platform is detachably mounted on the surface of the testing bench by the bolts, and the lateral pressure direction of the hydraulic cylinder on the right end of the beam reinforcement plate can be adjusted by adjusting the fixed position of the third support platform on the surface along the arc-shaped slide groove, thereby simulating the lateral force direction of the beam reinforcement plate when the car is subjected to a lateral impact, and can detect the bending resistance of the beam reinforcement plate when it is subjected to force in different directions.

[0008] Furthermore, two linear slide grooves are provided on the left end surface of the detection platform and are spaced apart along the front-to-back direction. Two bolts are installed in each linear slide groove. The first support platform is detachably mounted on the surface of the detection platform by bolts, and the distance between the first support platform and the second support platform can be adjusted by adjusting the fixed position of the first support platform on the surface along the linear slide groove, so as to be suitable for detecting beam reinforcement plates of different lengths.

[0010] Furthermore, a U-shaped limit plate is fixedly provided on the top of the second support platform, and the right end of the beam reinforcement plate can be inserted into the U-shaped limit plate to limit the beam reinforcement plate to prevent the right end of the beam reinforcement plate from deflecting too much at an angle during lateral pressure, especially to prevent the hydraulic cylinder and the right end of the beam reinforcement plate from accidentally slipping when the hydraulic cylinder applies lateral pressure to the right end of the beam reinforcement plate, causing the beam reinforcement plate to deflect at a large angle.

[0011] Furthermore, the inner side wall of the square box, the inner side wall of the horizontal clamping plate, the inner side wall of the vertical clamping plate and the inner side wall of the U-shaped limiting plate are all fixedly provided with a rubber pad layer, and each rubber pad layer can have an anti-slip property.

[0012] Furthermore, a push plate is fixed to the outer end of the piston rod of the hydraulic cylinder, and an arc-shaped groove is opened on the left side wall of the push plate. When lateral pressure is applied to the right end of the beam reinforcement plate, the hydraulic cylinder pushes the push plate to move laterally so that the push plate contacts the right end of the beam reinforcement plate. The right end of the beam reinforcement plate can extend into the arc-shaped groove on the left side wall of the push plate. A rubber sleeve is provided on the left side of the push plate for wrapping the right end of the beam reinforcement plate, which can reduce slipping and improve the stability of lateral pressure.

[0013] Furthermore, a protective cover is provided on the table top of the testing bench. The protective cover is a square box structure with an opening facing downward. The rear end bottom and the left and right end bottoms of the protective cover are fixed on the table top. The front side wall of the protective cover is an openable and closable door leaf structure.

[0014] Furthermore, the left side wall, right side wall and front door leaf of the protective cover are all made of transparent plates, which facilitates the perspective viewing of the interior of the protective cover when testing the resistance strength of the crossbeam reinforcement plate.

[0015] Furthermore, a ball screw linear module is installed on the inner top of the protective cover, and a 3D line laser contour sensor is installed on the slider of the ball screw linear module.

During the process of applying lateral pressure to the beam reinforcement plate, the 3D line laser contour sensor can be controlled to move in the left and right directions to perform high-precision size measurement and morphology analysis of the beam reinforcement plate between the first support platform and the second support platform, without being limited to a certain point on the beam reinforcement plate.

[0016] Furthermore, a plurality of angle scale lines with equal angle distribution are arranged on the right end table top of the detection table on the outside of the arc-shaped slide groove, a 0° mark is marked on the right side of the middle angle scale line, and 90° marks are marked on the outside of the angle scale lines at both ends, respectively.

The position of the third support platform can be adjusted to adjust the lateral pressure angle on the right end of the cross beam reinforcement plate. Starting the hydraulic cylinder can apply pressure to the right end of the cross beam reinforcement plate. Under the lateral extrusion pressure, the cross beam reinforcement plate is deformed. The 3D line laser profile sensor can perform high-precision dimensional measurement and morphological analysis on the cross beam reinforcement plate. The 3D line laser profile sensor is used to capture slight changes on the surface of the cross beam reinforcement plate, and its bending resistance can be evaluated based on the deformation of the cross beam reinforcement plate after being subjected to force. The lateral pressure direction of the hydraulic cylinder on the right end of the cross beam reinforcement plate can be adjusted by adjusting the fixed position of the third support platform on the table along the arc-shaped slide groove, thereby simulating the lateral force direction of the cross beam reinforcement plate when the automobile is subjected to a lateral impact, and can detect the bending resistance of the cross beam reinforcement plate when it is subjected to force in different directions.
