[0002] As a key component of both appearance and function, the installation dimensions and quality of automotive lights directly affect the overall appearance and quality of the vehicle. Manufacturing plants use automotive light opening gauges as inspection tools. For example, a patent publication (CN204944362U) describes an automotive taillight opening gauge. While existing automotive light opening gauges initially achieve positional fixation after positioning, they are prone to slight positional shifts during subsequent inspections, especially when checking for movement or measuring gaps in matching areas. They are even more difficult to maintain a stable position when subjected to external forces or their own weight. Furthermore, the operation of existing automotive light opening gauges is relatively complex. Utility Model Content

[0003] This utility model proposes an improved automotive lamp opening inspection fixture with an improved connection and positioning structure, which solves the problems of poor positioning stability and insufficient ease of operation of existing automotive lamp opening inspection fixtures.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A car light opening inspection tool includes an inspection tool body adapted to the outline of a car taillight. The inspection tool body is divided into a concave end and a convex end according to its structural shape. The concave end of the inspection tool body is connected to a number of magnetic suction components, and the convex end of the inspection tool body is provided with a number of measuring ports. The inner wall of the measuring port is fixedly connected to a mounting base.

[0006] An adjustable connecting plate is connected to the lower end of the mounting base, and a movable groove is provided inside the connecting plate. A hook is installed inside the movable groove via a rotating shaft, and an anti-loosening mechanism is integrated inside the hook.

[0007] An adjustment plate is fixedly connected to the side of the connecting plate, and a knob screw for locking the relative position of the inspection fixture body and the car lamp to be inspected is provided inside the adjustment plate.

[0008] Preferably, the magnetic attractor is a permanent magnet, and the magnetic attractor is connected to the concave end of the fixture body by a countersunk bolt.

[0009] Preferably, a limiting block is fixedly connected to the lower end of the mounting base, and an adjustment groove adapted to the limiting block is provided inside the connecting plate, and the connecting plate is sleeved on the outside of the limiting block through the adjustment groove.

[0010] Preferably, the anti-loosening mechanism includes a slide, an adjusting block, a baffle, a tension spring, and a spring cavity, and the adjusting block is fixedly connected to the outer end of the rotating shaft, and the hook has a spring cavity inside that is adapted to the adjusting block.

[0011] Preferably, the spring cavity has slides on both sides, and the bottom of the adjusting block is fixedly connected to a baffle that matches the slide. The adjusting block is fitted inside the spring cavity and the slide through the baffle.

[0012] Preferably, a tension spring is provided inside the spring cavity, with one end of the tension spring connected to the adjusting block and the other end of the tension spring connected to the bottom of the spring cavity.

[0013] Preferably, the end of the hook away from the pivot is provided as a corner transition structure, and the outer surface of the hook is plated with a hard chromium layer, the thickness of which is 0.05-0.1mm.

[0014] Preferably, the adjustment plate has a threaded hole inside that matches the knob screw, and the knob screw is connected inside the threaded hole.

[0015] Preferably, the movable end of the knob screw is embedded with a clamp plate for a movable connection.

[0016] Preferably, a buffer block is connected to the concave end of the inspection fixture body, and a number of positioning rods are connected to the outer side of the buffer block located at the side end of the magnetic suction component.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This automotive lamp opening gauge has a hook pin installed inside the movable slot via a rotating shaft. The hook pin is elastically connected to the gap in the lamp connection opening, ensuring a tight fit between the gauge body and the lamp. This prevents the hook pin from loosening or shifting during measurement, ensuring measurement accuracy. At the same time, during the inspection process, the threaded knob is rotated to further clamp the gauge. By rotating the threaded knob, the relative position of the gauge body and the hook pin can be locked and fixed, ensuring that the gauge body remains stable during the inspection process.

[0019] 2. Align the positioning rod with the positioning reference on the vehicle body to achieve the initial positioning of the fixture. The magnetic part at the concave end will quickly attract the metal substrate of the car lamp, so that the fixture is initially fixed on the surface of the car lamp. Push the hook to make its corner transition end contact and fit with the opening edge of the car lamp, making the installation and operation of the fixture body more convenient.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4 This utility model provides a technical solution: an automotive lamp opening inspection tool, including an inspection tool body 1. The overall shape of the inspection tool body 1 is adapted to the outline of the automotive taillight, and the inspection tool body 1 is divided into a concave end and a convex end according to its structural shape. Several sets of magnetic suction parts 4 are connected to the concave end of the inspection tool body 1, and several sets of measuring ports 2 are provided on the convex end of the inspection tool body 1. A mounting base 3 is fixedly connected to the inner wall of the measuring port 2. An adjustable connecting plate 5 is connected to the lower end of the mounting base 3, and a movable groove 6 is opened inside the connecting plate 5. A hook pin 8 is installed inside the movable groove 6 through a rotating shaft 7, and an anti-loosening mechanism is integrated inside the hook pin 8. An adjusting plate 9 is fixedly connected to the side end of the connecting plate 5, and a knob screw 10 is passed through the adjusting plate 9. The knob screw 10 is used to lock and fix the relative position of the inspection tool body 1 and the automotive lamp to be inspected.

[0027] Reference Figure 1 The magnetic suction component 4 is a permanent magnet, and the magnetic suction component 4 is detachably connected to the concave end of the inspection fixture body 1 by countersunk bolts. The lower end of the mounting base 3 is fixedly connected to the limiting block 11, and the connecting plate 5 has an adjustment groove 12 adapted to the limiting block 11 inside. The connecting plate 5 is sleeved on the outside of the limiting block 11 through the adjustment groove 12.

[0028] Reference Figure 2 , Figure 4The anti-loosening mechanism includes a slide rail 13, an adjusting block 14, a baffle 15, a tension spring 16, and a spring cavity 17. The adjusting block 14 is fixedly connected to the outer end of the rotating shaft 7. The hook pin 8 has a spring cavity 17 that matches the adjusting block 14. The slide rail 13 is provided on both sides inside the spring cavity 17. The baffle 15 that matches the slide rail 13 is fixedly connected to the bottom of the adjusting block 14. The adjusting block 14 is sleeved inside the spring cavity 17 and the slide rail 13 through the baffle 15. The tension spring 16 is provided inside the spring cavity 17. One end of the tension spring 16 is connected to the adjusting block 14, and the other end of the tension spring 16 is connected to the bottom of the spring cavity 17.

[0029] Reference Figure 3 , Figure 4 The end of the hook pin 8 away from the rotating shaft 7 is set as a corner transition structure, and the outer surface of the hook pin 8 is plated with a hard chrome layer with a thickness of 0.05-0.1mm. The adjusting plate 9 has a threaded hole 18 that matches the knob screw 10, and the knob screw 10 is connected to the inside of the threaded hole 18. The movable end of the knob screw 10 is embedded with a clamping plate 19 for movable connection. The concave end of the fixture body 1 is connected to a buffer block 21, and the outer side of the buffer block 21 is connected to several sets of positioning rods 22 on the side end of the magnetic suction part 4 for quick positioning to ensure the accuracy of the fixture installation position.

[0030] Using the above structure, when the fixture body 1 is securely installed and positioned, the concave end of the fixture body 1 is first oriented towards the part to be inspected on the taillight of the car. The positioning rod 22 is aligned with the positioning reference on the car body to achieve the initial positioning of the fixture. At this time, the magnetic suction part 4 at the concave end will quickly attract the metal substrate of the car lamp, so that the fixture is initially fixed on the surface of the car lamp. The buffer block 21 fits against the surface of the car lamp to avoid collision damage to the car lamp during the installation process. In this way, the fixture is quickly positioned and installed, laying the foundation for accurate measurement.

[0031] In use, when adjusting and measuring using the fixture body 1, according to the specific position of the opening to be inspected, first push the hook pin 8 to rotate around the rotating shaft 7 in the movable groove 6. The corner transition end of the hook pin 8 contacts and fits against the edge of the opening of the car light. Then, by rotating the knob screw 10 on the adjusting plate 9, the knob screw 10 pushes the clamping plate 19 towards the fixture body 1 through the engagement of the threaded hole 18, until the clamping plate 19 is tightly abutted against the side of the fixture body 1. The engagement of the adjusting groove 12 and the limiting block 11 ensures the accuracy of the adjustment direction, thus completing the locking and fixing of the relative position of the fixture body 1 and the hook pin 8. During this process, the tension spring 16 in the anti-loosening mechanism is always in a stretched state, generating a stable tension on the rotating shaft 7 through the adjusting block 14. During the measurement process, the adjusting block 14 is fitted inside the spring cavity 17 and the slide rail 13 through the baffle 15 to ensure the accuracy of the pulling direction. The adjusting block 14 and the baffle 15 always move along the inner wall of the slide rail 13 to prevent the hook pin 8 from becoming loose or shifting during the measurement process. After the hook pin 8 is in contact with the edge of the car lamp opening, the mounting seat 3 at the measuring port 2 is used as a reference. A special measuring tool (such as a gap gauge or surface difference gauge) is used to check the gap between the hook pin 8 and the edge of the car lamp opening. At the same time, the surface difference data of the opening part is obtained by combining the fit between the inspection fixture body 1 and the surface of the car lamp. In this way, the gap surface difference of the matching area is checked to see if it is consistent with the DTS design technical specifications. By measuring the gap surface difference, it is determined whether the state of the inspected product meets the production requirements.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
