The position offset increases the stability of the turntable 7 during operation, thereby increasing the stability of the headlight bracket. A placement groove 9 is provided on one side of the turntable 7, and a connecting block 10 is installed in the inner cavity of the placement groove 9. The size of the placement groove 9 is larger than that of the connecting block 10. A bracket group 11 is provided on the top of the connecting block 10. The connecting block 10 can support the bracket group 11, and the bracket group 11 can clamp and fix headlights of different angles and widths, thereby facilitating replacement by the staff and accelerating the rate at which the staff detects the luminous performance of the headlight. A connecting shell 12 is bolted to one side of the connecting block 10, and a limiting mechanism 13 is provided on one side of the connecting shell 12. With the cooperation of the limiting mechanism 13 and the connecting shell 12, the connecting block 10 can be fixed in the inside of the placement groove 9, so that the staff can replace the bracket group 11 faster, and there is no need for the staff to fix the bracket group 11 with screws and nuts, which accelerates the rate at which the staff detects the luminous performance of the headlight and reduces the workload of the staff, thereby increasing the use effect of the headlight bracket.
[0023] The guide mechanism 8 includes a support block 81, one side of which is bolted to the top of the base 1, the top of the support block 81 is slidably connected to the bottom of the turntable 7, a guide groove 82 is provided on one side of the support block 81, and the shape of the support block 81 is hollow, and the shape of the support block 81 corresponds to the shape of the guide groove 82, and a mounting block 83 is slidably connected to the surface of the guide groove 82, and one side of the mounting block 83 is bolted to the bottom of the turntable 7. Under the action of the rotating shaft 5, the turntable 7 can drive the support block 81 to rotate inside the guide groove 82. At the same time, under the support of the support block 81, the turntable 7 can be more stably rotated, which effectively prevents the turntable 7 from being offset during operation and prevents the situation where it cannot be detected, thereby increasing the stability of the headlight bracket.
[0024] The limiting mechanism 13 includes a moving rod 131, one side of the moving rod 131 is slidably connected to one side of the connecting shell 12, the surface of the moving rod 131 is slidably connected to one side of the turntable 7, a slider 132 is fixed to one side of the moving rod 131, the surface of the slider 132 is slidably connected to the inner cavity of the connecting shell 12, a compression spring 133 is fixed to one side of the slider 132, one side of the compression spring 133 is fixedly connected to the inner cavity of the connecting shell 12, under the action of the moving rod 131, the slider 132 compresses the compression spring 133, so that the slider 132 can enter the interior of the connecting shell 12, so that the staff can take the connecting block 10 out of the inner cavity of the placement groove 9, thereby facilitating the work. The staff replaces the bracket group 11, which speeds up the rate at which the staff replaces the bracket group 11. At the same time, under the action of the rebound of the compression spring 133, the slider 132 can fit tightly with the inner cavity of the turntable 7, so that the bracket group 11 can rotate with the turntable 7, so that the staff can fix the headlights of different shapes and angles in advance, thereby increasing the use effect of the bracket. The inner cavity of the connecting shell 12 is fixed with a guide rod 14, and the surface of the guide rod 14 is slidably connected with the inner cavity of the slider 132. The guide rod 14 is located at the center of the compression spring 133, which effectively prevents the compression spring 133 from being displaced during operation, thereby increasing the stability of the headlight bracket.
[0025] Working principle: First, the staff needs to install the bracket group 11 used in advance inside the placement groove 9, and use the moving rod 131 to make the slider 132 compress the compression spring 133, so that the slider 132 enters the interior of the connecting shell 12, and then the connecting block 10 drives the bracket group 11 into the inner cavity of the placement groove 9. Under the action of the compression spring 133 rebounding, the slider 132 can return to its original position and fit tightly with the inner cavity of the turntable 7, so that the bracket group 11 can rotate with the turntable 7. When it is necessary to detect the headlights of different widths and angles, the staff uses the stepper motor 2 to make the first spur gear 3 drive the second spur gear 4 to rotate, and the second spur gear 4 drives the bearing seat 6 to rotate through the rotating shaft 5, and rotates the headlight to be detected to the detection point, which speeds up the staff's detection rate. At the same time, the turntable 7 drives the mounting block 83 to rotate inside the guide groove 82, and with the support of the support block 81, the turntable 7 can be effectively prevented from being offset. When all the headlights are detected, the staff can close the device.
