[0023] Embodiment: A fixing device for detecting automobile headlights, such as Figure 1-Figure 3As shown, it includes a headlight light pattern test machine body 1, a headlight light pattern test board 101, a supporting base plate 2, a headlight placement seat 3, a lifting cylinder 4 and a limit rod 5. The upper inner part of the headlight light pattern test machine body 1 is a test platform for testing the light pattern and intensity of the headlight body 100, wherein the rear part of the test platform is movably provided with a headlight light pattern test board 101, and the headlight light pattern test board 101 is slidably provided on the test platform, and the light intensity of each mode at different distances from the headlight body 100 is achieved by sliding the headlight light pattern test board 101 back and forth; the front part of the test platform is provided with a supporting base plate 2, and the headlight placement seat 3 and the lifting cylinder 4 are provided on the supporting base plate 2 through a movable component, and the headlight placement seat 3 and the lifting cylinder 4 are provided. There are two cylinders 4 respectively, and the movable end of the piston rod of the lifting cylinder 4 is connected to the limiting rod 5. The limiting rod 5 is used to limit the headlamp body 100 placed on the headlight placement seat 3. The end of the limiting rod 5 away from the piston rod of the lifting cylinder 4 is made of soft material. The setting of the soft material can effectively avoid scratches or other physical damage to the surface of the headlamp body 100 during the fixation process, thereby ensuring the integrity of the headlamp body 100. In addition, the detachable connection between the limiting rod 5 and the piston rod of the lifting cylinder 4 makes it easy to select a limiting rod 5 suitable for the shape and size of the headlamp body 100. Therefore, the shape of the limiting rod 5 is not limited, thereby effectively limiting headlamp bodies 100 of different sizes and shapes on the headlight placement seat 3.

[0024] like Figure 3 As shown, the moving assembly includes an electric slide rail 21 installed on the supporting base plate 2 and a mounting plate 22 slidably installed on the electric slide rail 21. The headlight holder 3 and the lifting cylinder 4 are both installed on the mounting plate 22, and the two lifting cylinders 4 are symmetrically installed on both sides of the center line of the mounting plate 22. The two headlight holders 3 are symmetrically installed on both sides of the mounting plate 22 with the lifting cylinder 4 as the center. The headlight holder 3 and the mounting plate 22 are detachably connected to facilitate replacement of the headlight holder 3 suitable for the vehicle body, thereby allowing users to select a suitable headlight holder 3 for replacement according to different vehicle models or headlight types, greatly enhancing the applicability of the device.

[0025] like Figure 2 and Figure 4As shown, the left and right sides of the front of the test platform of the headlight type test machine body 1 are installed with vertical frames 6, a horizontal plate 8 is slidably set between the two vertical frames 6, and two two-way cylinders 9 are slidably set on the horizontal plate 8. The movable end of the piston rod of the two-way cylinder 9 is connected with a clamping block 10, which is used to clamp the headlight body 100. The connection between the clamping block 10 and the piston rod of the two-way cylinder 9 is a movable connection to facilitate the replacement of the clamping block 10 that adapts to the shape of the headlight body 100. The movable connection design between the clamping block 10 and the piston rod of the two-way cylinder 9 is practical. Now, according to actual needs, the clamping blocks 10 of different shapes can be quickly replaced to adapt to various types of headlight fixing requirements. A soft pad 1001 is provided on the side of the clamping block 10 that contacts the headlight body 100. The provision of the soft pad 1001 can not only increase the friction between the clamping block 10 and the headlight body 100, but also avoid rigid contact between the clamping block 10 and the headlight body 100, thereby preventing the clamping block 10 from causing physical damage to the headlight body 100 when clamping the headlight body 100, thereby ensuring the integrity of the headlight body 100.

[0026] like Figure 4 As shown, an electric telescopic rod 11 is provided in the vertical frame 6, and the movable end of the electric telescopic rod 11 is fixedly connected to the horizontal plate 8. The electric telescopic rod 11 is used to drive the horizontal plate 8 to rise and fall along the slide groove in the vertical frame 6, thereby driving the two-way cylinder 9 and the clamping block 10 to rise and fall, thereby clamping the headlight body 100.

[0027] like Figure 2 and Figure 3 As shown, a positioning block 7 is provided on the front outer wall of the headlight placement seat 3 to provide positioning information for the clamping block 10 to clamp the headlight body 100. The positioning block 7 cooperates with the control unit installed on the main body 1 of the headlight light type tester to ensure the accurate position of the headlight body 100 during the test process, reduce errors caused by human factors; at the same time, improve the degree of automation, shorten the detection cycle, and improve work efficiency.

[0028] When in use, first extend the piston rod of the lifting cylinder 4 upward to move the limiting rod 5 upward, then place the two large headlight bodies 100 to be tested on the headlight placement seat 3, the piston rod of the lifting cylinder 4 contracts downward, and the limiting rod 5 moves down until it is away from the end of the piston rod of the lifting cylinder 4 and abuts against the headlight body 100, thereby preliminarily positioning the headlight body 100 on the headlight placement seat 3; after the headlight body 100 is placed in place, the positioning block 7 on one side of the headlight placement seat 3 sends the position information of the headlight placement seat 3 to the control unit, and the control unit controls the electric slide rail 21 to drive the mounting plate 22 to move horizontally, until the headlight body 100 placed on the headlight placement seat 3 moves to just below the two-way cylinder 9, thereby moving the headlight body 100 to just below the two-way cylinder 9, thereby ensuring that the clamping block 1 0 can accurately clamp the headlamp body 100 to avoid measurement errors caused by position offset; then the electric telescopic rod 11 contracts downward, thereby driving the cross plate 8 and the two-way cylinder 9 and the clamping block 10 located on the cross plate 8 to move downward, until the cross plate 8 moves down to an appropriate position, and the clamping block 10 is driven to move closer to the headlamp body 100 through the telescopic function of the piston rod of the two-way cylinder 9 until the headlamp body 100 is completely clamped, thereby fixing the headlamp body 100, thereby providing convenient conditions for the illumination, intensity and air tightness testing of the headlamp body 100; then, the operator can start the car light type tester main body 1 through the control panel, and the car light type test board 101 at the rear of the test platform starts to work, so as to realize accurate testing of the illumination mode, intensity and air tightness of the headlamp.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
