Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts detection, in particular to a device for detecting the anti-bending strength of automobile parts. Background Art
[0002] A car is a complex electromechanical hybrid system comprised of tens of thousands of components. These components are diverse, yet each performs its own unique function within the vehicle. Typically, auto parts manufacturers test their components after production to ensure quality and reliability. Automakers also test the performance of components after installation into the vehicle. Auto parts primarily consist of eight major components: steering system components, running system components, electrical and instrument system components, lighting, modification components, engine components, transmission system components, and brake system components. The vehicle frame generally consists of longitudinal beams and cross beams. Cross beams primarily ensure torsional rigidity, withstand longitudinal loads, and support key components within the vehicle. This requires sufficient strength in the design of cross beams, and their bending resistance is tested after production.
[0003] Since some rod-like structures of the vehicle crossbeam are of different lengths, these rod-like structures need to be placed on pads for easy fixation during testing. In addition, the distance between the two pads needs to be adjusted according to the length of the rod-like structure to be tested for better testing. Since the pads are mostly made of metal and are heavy, manual control is time-consuming and labor-intensive, and it is difficult to control the distance accuracy between the two pads.
[0004] To this end, the utility model provides a device for detecting the bending strength of automobile parts to solve the above problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the utility model provides a device for testing the bending strength of automobile parts, which solves the above problems. By starting the cylinder, the movement of the docking block can be controlled. When the docking block moves upward, the action of the connecting rod can make the two assembly plates move away from each other on both sides of the operating plate, and then drive the installation plate to move together to complete the distance adjustment. Since the cross plate slides inside the cross slide block, the stability of the assembly plate and the cross plate can be ensured. When the cylinder moves the docking block downward, the two assembly plates are brought closer to each other. The roller can reduce the friction resistance when the cross plate and the assembly plate move, making their movement more stable. The reinforcing rib plate is used to strengthen and reinforce the operating plate; the component to be tested is placed on the V-shaped pad. Due to the special structure of the V-shaped pad, objects of different widths can be placed. Then, by rotating the swivel, the screw can be driven to rotate, and the screw will move downward, and drive the slider to move downward to press the arc pressure block on the object to be tested to press it tightly and fix it. Then, the press is started to perform the bending strength test.
[0006] The top of the driving member is mounted on a link ram, and the link ram is located adjacent the drive member, and the bottom of the driving member is mounted on a link ram of the driving member.
[0007] Furthermore, a reinforcing rib plate is fixedly connected to one side of the operating panel.
[0008] By adopting the above technical solution, the operation panel is strengthened.
[0009] Furthermore, the downward pressing and fixing assembly includes a limiting sliding rod, and one end of the limiting sliding rod is fixedly connected to the top plate.
[0010] By adopting the above technical solution, other components can be installed.
[0011] Furthermore, the top plate is internally threadedly connected to a screw, one end of the screw is rotatably connected to a slider, both ends of the slider are internally slidably connected to the outer wall of the limiting slide rod, and the bottom of the slider is fixedly connected to an arc-shaped pressure block.
[0012] By adopting the above technical solution, the parts to be inspected can be pressed and fixed.
[0013] Furthermore, one end of the screw is fixedly connected to a swivel.
[0014] By adopting the above technical solution, it is easy to drive the screw to rotate.
[0015] Furthermore, a V-shaped pad is fixedly connected to the top of the mounting plate, and the downward pressing and fixing assembly also includes a press, which is fixedly installed on the outer side of the operating panel.
[0016] By adopting the above technical solution, parts to be inspected of different widths can be placed.

[0019] 1. This automotive parts bending strength testing device can control the movement of the docking block by activating the cylinder. When the docking block moves upward, the two assembly plates can move away from each other on both sides of the operating plate through the action of the connecting rod, and then the mounting plates can be driven to move together to complete the distance adjustment.
[0020] 2. The device for testing the bending strength of automobile parts places the part to be tested on a V-shaped pad. Due to the special structure of the V-shaped pad, objects of different widths can be placed. Then, by rotating the swivel, the screw can be driven to rotate.

[0028] The present application will be further described in detail below through the accompanying drawings and examples.
[0029] Reference Figures 1 to 4 The embodiment of the present application provides a device for testing the bending strength of automobile parts, comprising an operating panel 1, a distance adjustment assembly 2 provided on one side of the operating panel 1, and a downward pressing fixing assembly 3 provided on the top of the operating panel 1; the distance adjustment assembly 2 includes a longitudinal chute block 21, which is fixedly connected to one side of the operating panel 1, and a docking block 23 is slidably connected to the interior of the longitudinal chute block 21; a cylinder 22 is fixedly installed on one side of the operating panel 1, and the movable end of the cylinder 22 is fixedly connected to the docking block 23; a transverse chute block 26 is fixedly connected to the top of the operating panel 1, and a connecting rod 24 is rotatably connected to one side of the docking block 23, and one end of the connecting rod 24 is rotatably connected to an assembly plate 25; a transverse plate 27 is fixedly connected to one side of the assembly plate 25, and one side of the transverse plate 27 is slidably connected to the interior of the transverse chute block 26; a roller 28 is fixedly installed on the bottom of the transverse plate 27, and a mounting plate 29 is fixedly connected to the transverse plate 27 and the top of the assembly plate 25. A reinforcing rib plate 210 is fixedly connected to one side of the operating panel 1.
[0030] During specific implementation: by starting the cylinder 22, the docking block 23 can be controlled to move on the longitudinal slide block 21. When the docking block 23 moves upward, the two assembly plates 25 can be moved to the two sides of the operating plate 1 away from each other through the action of the connecting rod 24, and then the mounting plate 29 can be driven to move together to complete the distance adjustment. Since the cross plate 27 slides inside the cross slide block 26, the stability of the assembly plate 25 and the cross plate 27 when moving can be ensured. When the cylinder 22 makes the docking block 23 move downward, the two assembly plates 25 will be closer to each other. The roller 28 can reduce the friction resistance when the cross plate 27 and the assembly plate 25 move, making it more stable when moving. The reinforcing rib plate 210 is used to strengthen the operating plate 1, and the cylinder 22 is used to control the distance change accuracy for better control.
[0031] Reference Figures 1 to 4 In one aspect of this embodiment, the downward pressing and fixing assembly 3 includes a limiting slide 31, one end of which is fixedly connected to a top plate 32. A screw 33 is internally threadedly connected to the top plate 32, and one end of the screw 33 is rotatably connected to a slider 35. The interior ends of the slider 35 are slidably connected to the outer wall of the limiting slide 31, and the bottom of the slider 35 is fixedly connected to an arc-shaped pressure block 36. One end of the screw 33 is fixedly connected to a swivel 34. A V-shaped pad 37 is fixedly connected to the top of the mounting plate 29. The downward pressing and fixing assembly 3 also includes a press 38, which is fixedly mounted on the outside of the operating panel 1.
[0032] During specific implementation: the part to be tested is placed on the V-shaped pad 37. Due to the special structure of the V-shaped pad 37, objects of different widths can be placed. Then, by rotating the swivel 34, the screw 33 can be driven to rotate. The screw 33 will then move downward and drive the slider 35 to move downward together to press the arc-shaped pressure block 36 on the object to be tested to tighten it and fix it. After that, the press 38 is started to test the bending strength.
[0033] All electrical equipment in this solution are powered by external power supplies.
[0034] Working principle: By starting the cylinder 22, the docking block 23 can be controlled to move on the longitudinal slide block 21. When the docking block 23 moves upward, the two assembly plates 25 can be moved to the two sides of the operating plate 1 away from each other through the action of the connecting rod 24, and then the mounting plate 29 can be driven to move together to complete the distance adjustment. Since the cross plate 27 slides inside the cross slide block 26, the stability of the assembly plate 25 and the cross plate 27 when moving can be ensured. When the cylinder 22 makes the docking block 23 move downward, the two assembly plates 25 will be brought closer to each other, and the roller 28 can reduce the movement of the cross plate 27 and the assembly plate 25. The friction resistance during movement makes it move more smoothly. The reinforcing rib plate 210 is used to strengthen the operating panel 1, and the cylinder 22 is used to control the distance change accuracy for better control. The part to be tested is placed on the V-shaped pad 37. Due to the special structure of the V-shaped pad 37, objects of different widths can be placed. Then, by rotating the swivel 34, the screw 33 can be driven to rotate. The screw 33 will then move downward and drive the slider 35 to move downward together. Pressing the arc-shaped pressing block 36 on the object to be tested can fix it, and then starting the press 38 can perform a bending strength test.
