Description
Technical Field
[0001] This utility model relates to the field of automotive engineering testing technology, specifically to a positioning and fixing fixture for vehicle body strength testing. Background Technology
[0002] Automotive engineering testing refers to the process of simulating real-world usage scenarios to test and evaluate various aspects of a vehicle's performance during its research, development, production, and quality control. Body strength testing is an important part of automotive body engineering testing. It mainly tests the stability and resilience of the body structure under external forces by simulating collisions, torsion, and tension, thereby assessing whether the body can ensure driving safety and providing a key basis for improving the overall quality of the vehicle.
[0003] Existing technologies often have the following problems when used:
[0004] In automotive engineering testing, the testing of vehicle body strength is particularly important, as it relates to the overall safety performance of the vehicle. In the testing of vehicle body strength, it is often necessary to conduct concentrated testing on the body structure of the car door and roof. However, the edges of the car door and roof structure usually have a certain curvature, making it difficult to adjust the fixing angle according to the curvature of the body edge during the positioning and fixing process. In addition, the width specifications of car door and roof structures vary, making it difficult to fully fix them for different width specifications of the body, resulting in poor universality of positioning and fixing tooling. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a positioning and fixing fixture for vehicle body strength testing, which can effectively solve the problems of difficulty in adjusting the fixing angle according to the curvature of the vehicle body edge and inconvenience in fully fixing different specifications and types of vehicle bodies, resulting in poor versatility of the positioning and fixing fixture.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a positioning and fixing fixture for vehicle body strength testing, including a fixing frame;
[0008] An adjustable positioning assembly is used to adjust the angle of positioning and fixing the vehicle body according to the curvature of the vehicle body. There are four adjustable positioning assemblies, which are evenly distributed on the outer surface of the fixed frame. Each adjustable positioning assembly includes an electric push rod fixedly installed on the outer surface of the fixed frame. The output end of the electric push rod passes through the fixed frame and is fixedly connected to a concave rotating seat. A T-shaped rotating block is rotatably connected to the concave rotating seat through a transition shaft. A clamping and fixing component is fixedly connected to the upper end face of the T-shaped rotating block.
[0009] The clamping and fixing components are used to fully clamp and fix the edges of the vehicle body.
[0010] Furthermore, the adjustable positioning component also includes a first low-speed motor fixedly installed on the outer wall of the concave rotating seat, and the output end of the first low-speed motor is fixedly connected to one end of the adapter shaft.
[0011] Furthermore, the clamping and fixing component includes a clamping base fixedly connected to the upper end face of the T-shaped rotating block. A bidirectional screw is rotatably connected to the side wall of the clamping base. Two guide blocks are threadedly connected to the bidirectional screw, and clamping plates are fixedly connected to the upper end faces of the two guide blocks.
[0012] Furthermore, the clamping and fixing component also includes a second low-speed motor fixedly installed on the outer wall of the clamping base. The output end of the second low-speed motor is fixedly connected to one end of the bidirectional screw. Limiting rollers are fixedly installed on the lower end faces of the two guide blocks. A limiting slide rail is fixedly connected to the upper end face of the clamping base. The limiting rollers match the inner side of the limiting slide rail.
[0013] Furthermore, a silicone pad is fixedly connected to one side of the clamp plate near the center of the bidirectional screw.
[0014] Furthermore, the outer surface of the limiting roller is provided with transverse anti-slip texture.
[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0016] This invention features an adjustable positioning component. By driving the T-shaped rotating block to rotate relative to the concave rotating seat at a certain angle, the clamping base and the clamping plate can rotate synchronously. This allows the clamping plate to be adjusted to a fixed angle that adapts to the curvature of the vehicle body edge, thus securing the edge of the vehicle body and ensuring the stability of the vehicle body positioning. Simultaneously, by controlling the electric push rod, the clamping base and the clamping plate can be moved closer to the center of the fixed frame, allowing the clamping plate to fully secure vehicle bodies of different widths and specifications. This effectively improves the versatility of the vehicle body positioning and fixing fixture. Furthermore, by driving the two clamping plates to move in opposite directions, the positioning, fixing, and release of the vehicle body can be achieved, further enhancing the ease of use of the vehicle body positioning and fixing fixture.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] The present invention will be further described below with reference to the embodiments.
[0024] Example: Refer to Figures 1 to 3 A positioning and fixing fixture for vehicle body strength testing includes a fixed frame 1 and adjustable positioning components. The adjustable positioning components are used to adjust the angle of positioning and fixing the vehicle body according to the curvature of the vehicle body. There are four adjustable positioning components, which are evenly distributed on the outer surface of the fixed frame 1. The adjustable positioning components include an electric push rod 2 fixedly installed on the outer surface of the fixed frame 1. The output end of the electric push rod 2 passes through the fixed frame 1 and is fixedly connected to a concave rotating seat 3. A T-shaped rotating block 5 is rotatably connected to the concave rotating seat 3 through a transition shaft 4. The adjustable positioning components also include a first low-speed motor 6 fixedly installed on the outer wall of the concave rotating seat 3. The output end of the first low-speed motor 6 is fixedly connected to one end of the transition shaft 4.
[0025] The No. 1 low-speed motor 6 drives the adapter shaft 4 and the T-shaped rotating block 5 to rotate at a certain angle, so that the clamping base 7 and the clamping plate can rotate synchronously, thereby allowing the clamping plate 10 to be adjusted to a fixed angle that adapts to the curvature of the vehicle body edge, and the clamping plate 10 is used to fix the vehicle body edge, which helps to ensure the stability of the vehicle body positioning and fixing.
[0026] Several electric push rods 2 are controlled to drive the clamping base 7 and the clamping plate 10 to move closer to the middle of the fixed frame 1, so that the clamping plate 10 can fully fix the body of different width specifications, thereby effectively improving the versatility of the body positioning and fixing fixture.
[0027] Reference Figures 1 to 3 The upper end face of the T-shaped rotating block 5 is fixedly connected to a clamping and fixing component. The clamping and fixing component is used to fully clamp and fix the edge of the vehicle body. The clamping and fixing component includes a clamping base 7 fixedly connected to the upper end face of the T-shaped rotating block 5. A bidirectional screw 8 is rotatably connected to the side wall of the clamping base 7. Two guide blocks 9 are threadedly connected to the bidirectional screw 8. A clamping plate 10 is fixedly connected to the upper end face of each of the two guide blocks 9. A silicone pad 14 is fixedly connected to one side of the clamping plate 10 near the center position of the bidirectional screw 8. The clamping and fixing component also includes a second low-speed motor 11 fixedly installed on the outer wall of the clamping base 7. The output end of the second low-speed motor 11 is fixedly connected to one end of the bidirectional screw 8. Limiting rollers 12 are fixedly installed on the lower end face of each of the two guide blocks 9. The outer surface of the limiting rollers 12 is provided with transverse anti-slip texture. A limiting slide rail 13 is fixedly connected to the upper end face of the clamping base 7. The limiting rollers 12 match the inner side of the limiting slide rail 13.
[0028] The bidirectional screw 8 is driven to rotate by the second low-speed motor 11, so that the two guide blocks 9 on the bidirectional screw 8 can drive the two clamping plates 10 to move in opposite directions, so as to fully clamp and fix the edge of the car body. After the test is completed, the bidirectional screw 8 can be driven to rotate in the opposite direction, so that the two clamping plates 10 move in opposite directions and release the fixation of the car body. This makes it easy to fix and release the car body, which helps to improve the ease of use of the car body positioning and fixing fixture.
[0029] The working principle of this utility model is as follows:
[0030] In use, first place the car body structure of the car door or roof inside the fixed frame 1, so that the center of the car body coincides with the center of the fixed frame 1. Then measure the curvature of the edge of the car body and control the No. 1 low-speed motor 6 to start. The No. 1 low-speed motor 6 drives the adapter shaft 4 and the T-shaped rotating block 5 to rotate a certain angle, so that the clamping base 7 and the clamping plate can rotate synchronously. This allows the clamping plate 10 to be adjusted to a fixed angle that adapts to the curvature of the edge of the car body, and the clamping plate 10 is used to fix the edge of the car body, which helps to ensure the stability of the car body positioning and fixing.
[0031] If the vehicle body to be tested has different width specifications, several electric push rods 2 can be controlled to drive the clamping base 7 and clamping plate 10 to move closer to the middle of the fixed frame 1, so that the clamping plate 10 can fully fix the vehicle body with different width specifications, thereby effectively improving the versatility of the vehicle body positioning and fixing fixture.
[0032] During the process of fixing the car body using clamping plate 10, the second low-speed motor 11 can be started, and the second low-speed motor 11 drives the bidirectional screw 8 to rotate, so that the two guide blocks 9 on the bidirectional screw 8 can drive the two clamping plates 10 to move in opposite directions, so as to fully clamp and fix the edge of the car body using the two clamping plates 10. After the test is completed, the bidirectional screw 8 can be driven to rotate in the opposite direction, so that the two clamping plates 10 move in opposite directions and release the fixation of the car body. This makes it easy to fix and release the car body, which helps to improve the ease of use of the car body positioning and fixing fixture.
[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
