Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically a gauge for measuring the tolerance range of a vehicle lighting assembly. Background Technology

[0002] In the automobile manufacturing process, the headlight assembly, as an important appearance and functional component, has a crucial impact on the assembly quality, appearance coordination, and lighting performance of the entire vehicle due to its dimensional accuracy and tolerance control. Precise tolerance control ensures that the headlight assembly fits well with surrounding components when installed on the vehicle body, avoiding problems such as excessive or insufficient gaps or inconsistent surface differences, thereby improving the overall quality and aesthetics of the vehicle. Traditional inspection fixtures are often complex in structure and cumbersome in operation, requiring technicians to spend a lot of time installing, adjusting, and measuring the headlights, increasing their workload. Moreover, they mostly rely on manual fixed-point measurements, resulting in a small measurement range and incomplete data. Therefore, this utility model proposes an inspection fixture for measuring the tolerance range of the headlight assembly to solve the above problems. Utility Model Content

[0020] A base 1 has a monitor 2 fixedly mounted on its top. A workbench 3 is fixedly mounted on the top of the base 1. A gantry 4 is fixedly mounted on the top of the workbench 3. A first motor 5 is mounted on the side of the gantry 4. A drive rod 6 is fixedly mounted on the side of the gantry 4. A movable block 7 is slidably mounted on the side of the drive rod 6. A simulated screw is provided on the top of the movable block 7. A connecting block 8 is fixedly connected to the bottom of the movable block 7. A rotating wheel 9 is rotatably mounted on the bottom of the connecting block 8. A turbine groove 17 is provided on the bottom of the rotating wheel 9. A sliding column 18 is fixedly connected to the top of the positioning plate 10. The sliding column 18 is slidably disposed in the sliding groove 11. By adjusting and rotating the rotating wheel 9, the sliding column 18 drives the positioning plate to slide and clamp and limit the headlight body 16 under the sliding cooperation of the turbine groove 17 and the sliding column 18.

[0021] A positioning plate 10 is slidably connected to the bottom of the rotating wheel 9. A spiral rod 19 is inserted into the side of the positioning plate 10. The top of the spiral rod 19 is inserted into the side of the connecting block 8. A detection hole 20 is opened on the side of the positioning plate 10. With the detection hole 20, the handheld measuring device 26 can perform point measurement on the part clamped by the positioning plate 10 to obtain more comprehensive data.

[0022] The top of the workbench 3 is provided with a slide groove 11, and a movable frame 12 is slidably connected to the top of the slide groove 11. A square block 13 is fixedly connected to the side of the movable frame 12, and simulated screws are also provided on the side of the movable frame 12. A movable base 14 is slidably provided on the side of the square block 13, and a compression spring 15 is fixedly connected to the side of the movable base 14. Under the pull of the compression spring 15, the movable base 14 will clamp and limit the bottom of the headlight body 16.

[0023] The drive rod 6 is synchronously connected to the output shaft of the first motor 5. The headlight body 16 is placed on the top of the movable base 14. The limit bracket 21 is fixedly installed on the top of the worktable 3. The end of the drive rod 6 away from the mast 4 is fixedly connected to the mounting base 22. The second motor 23 is fixedly installed on the top of the mounting base 22. The first motor 5 drives the drive rod 6 to rotate, and precisely controls the distance of the movable block 7 moving on the side of the drive rod 6. The distance between the movable block 7 and the detection base 25 is controlled to ensure that when the detection base 25 drives the measuring device 26 to move and detect, there will be no deviation in the relative position with the headlight body 16, thereby improving the accuracy of the acquired data.

[0024] A transmission screw 24 is synchronously installed at one end of the output end of the second motor 23, which passes through the mounting base 22. The transmission screw 24 is built into the inner side of the limit bracket 21. A test seat 25 is slidably arranged on the side of the transmission screw 24, and a measuring device 26 is installed on the side of the test seat 25. The test seat 25 is connected to the monitor 2 via a communication line. The measuring device 26 slides up and down under the drive of the transmission screw 24, which can perform comprehensive tolerance range measurement on the surface of the vehicle headlight. The test seat 25 inputs the test data into the monitor 2 via the communication line, making the reading of the test data more accurate and ensuring the quality of the product.

[0025] In practical use: First, adjust the spatial posture of the headlight according to the surface that the headlight needs to detect, and then place it on top of the movable base 14. Under the action of the compression spring 15, the movable base 14 slides on the side of the square block 13 and initially clamps and limits the bottom of the headlight body 16. Then, use simulated screws to fix the movable frame 12 to the headlight body 16. Second, move the movable frame 12 and the headlight body 16 to the position below the movable seat. Use the simulated screws on the top of the movable seat to fix the movable seat to the top of the headlight body 16. Then rotate the rotating wheel 9, and the turbine groove 17 slides against the top of the positioning plate 10. The column 18 slides, allowing the positioning plate 10 to slide on the side of the U-shaped rod 19 and fix the top position of the headlight body 16. After the headlight body 16 is clamped and fixed, the first motor 5 is started. The first motor 5 drives the drive rod 6 to rotate, precisely controlling the moving block 7 to move a distance on the side of the drive rod 6, which can transport the headlight body to the detection range of the measuring device 26. The second motor 23 is started, driving the transmission screw 24 to rotate, causing the measuring device 26 to slide up and down on the side of the transmission screw 24, which can perform comprehensive tolerance range measurement on the headlight surface. The test seat 25 inputs the detection data into the monitor 2 through the communication line.
