Description

Technical Field

[0001] This utility model relates to the field of automotive lamp lens module testing technology, and in particular to a general tooling for automotive lamp lens modules. Background Technology

[0002] Currently, after the automotive headlight lens module is assembled, a fixture needs to be designed according to the mounting hole size to secure it to the vehicle for a series of optical, electronic, and heat resistance tests, referencing the vehicle's mounting location. Especially during light distribution testing, because the module fixture cannot accommodate dimming motors, screws, ball joints, or other dimming structures, the lens module can only adjust the light pattern by adding shims. However, light distribution testing has extremely high requirements, and relying on shims cannot achieve the optimal light pattern for testing. This inaccurate adjustment of the light pattern during lens module light distribution testing may introduce errors in the test results. Furthermore, since the module size varies for each project, corresponding mounting fixtures must be designed for different projects. These fixtures cannot be shared between different projects, significantly increasing the workload for designers. After all tests are completed, the non-interchangeable fixtures for that project become idle, resulting in substantial asset waste. Additionally, changing to different sized lens modules takes a long time, negatively impacting testing efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a universal tooling for automotive lamp lens modules. It can meet the installation and testing of lens modules of different sizes, has a fast adjustment speed, is easy to adjust the light shape, and has higher testing accuracy.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A general tooling for automotive headlight lens modules includes a base plate and two side plates that are laterally slidably mounted on the base plate, with two sliders slidably mounted on each side plate vertically.

[0006] Each slider has a protruding mounting part at its front end, and the mounting part has a screw mounting hole for locking and mounting the lens module. A spring is coaxially arranged at the front end of the screw mounting hole.

[0007] Furthermore, a horizontal groove is provided on the base plate, and the bottom ends of the two side plates are slidably assembled in the groove.

[0008] Furthermore, the slide groove has two first screw adjustment holes opened laterally, and a first locking screw suitable for locking the side plate is slidably inserted into each of the two first screw adjustment holes.

[0009] Furthermore, each of the side plates is provided with two vertically arranged second screw adjustment holes, and a second locking screw suitable for locking the slider is slidably inserted into each second screw adjustment hole.

[0010] Furthermore, each slider is locked by two flush second locking screws, and the two flush second locking screws are locked together by a long strip washer.

[0011] Furthermore, the front end face of the mounting part is provided with a spring hole groove coaxial with the screw mounting hole, and one end of the spring is embedded and fixed in the spring hole groove.

[0012] Furthermore, the depth of the spring hole groove is 5mm.

[0013] Furthermore, handles are provided on both sides of the base plate.

[0014] Furthermore, scales are provided on both the surface of the base plate and the side of the side plate.

[0015] Furthermore, the side plate is L-shaped.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model uses two side plates that can slide laterally and four sliders that can slide up and down on the two side plates to flexibly adjust the lateral distance between the two side plates and the vertical distance between each pair of sliders. Combined with the screw mounting holes on the mounting mating part at the front end of the slider, the lens module can be installed.

Detailed Implementation

[0026] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] like Figure 1-5 As shown, in this embodiment, a universal tooling for automotive headlight lens modules is provided, which mainly consists of a base plate 1, two side plates 2, and four sliders 3. The base plate 1 has handles 7 on both sides for easy movement and placement. The two side plates 2 are slidably mounted laterally on the base plate 1, and the four sliders 3 are vertically slidably mounted on the two side plates 2 in pairs. Each slider 3 also has a protruding mounting part 30 at its front end for easy installation and testing of the lens module. Each mounting part 30 has a screw mounting hole 301 for locking the lens module in place, and a spring 6 is coaxially mounted at the front end of the screw mounting hole 301.

[0028] refer to Figure 3 , 5 As shown, in this embodiment, a high-strength spring 6 is provided at the front end of the screw mounting hole 301, so that when the lens module 9 is installed and tested, it can be locked with the screw mounting holes 301 on the four mounting mating parts 30 by four locking screws 90. The four locking screws 90 will compress the spring 6. The locking distance of a single locking screw 90 can be adjusted according to optical requirements to control the compression of the spring 6, thereby adjusting the beam shape position to meet the test requirements. This makes it more convenient and faster to adjust to a suitable beam shape, achieves precise beam shape adjustment, and is conducive to high standard test accuracy.

[0029] It is worth mentioning that a spring hole groove 302 coaxial with the screw mounting hole 301 is provided on the front end face of the mounting part 30. One end of the spring 6 is embedded and fixed in the spring hole groove 302, and the depth of the spring hole groove 302 is 5mm. The exposed length of the spring 6 is 8-10mm, and the compression is not less than 5mm. This is beneficial for the precise adjustment of the light shape during testing.

[0030] Specifically, in this embodiment, a sliding groove 10 is laterally provided on the base plate 1, and the two side plates 2 are L-shaped with their bottom ends slidably fitted into the sliding groove 10 to ensure the sliding stability and mechanical precision of the side plates 2. At the same time, in order to lock the side plates 2, two first screw adjustment holes 11 are laterally provided on the sliding groove 10. First locking screws 4 suitable for locking the side plates 2 are slidably inserted into both first screw adjustment holes 11. When the two side plates 2 slide and adjust, the first locking screws 4 will slide along in the first screw adjustment holes 11. When the two side plates 2 slide into place, the position of the side plates 2 can be fixed by tightening the first locking screws 4 from below. Wafers can also be added to enhance the locking stability and strength.

[0031] Specifically, in this embodiment, each side plate 2 has two vertically arranged second screw adjustment holes 20. A second locking screw 5, suitable for locking the slider 3, slides through each second screw adjustment hole 20. Each slider 3 is locked by two flush second locking screws 5, which are also locked together by a long strip washer 50 to ensure consistent locking and straightness of the sliding. When the slider 3 slides up and down, the second locking screws 5 slide within the second screw adjustment holes 20. Once the slider 3 is in position, tightening the second locking screws 5 fixes the position of the slider 3.

[0032] Through the above design, this embodiment uses two side plates 2 that can slide laterally and four sliders 3 that can slide up and down on the two side plates 2. The lateral distance between the two side plates 2 and the vertical distance between each pair of sliders 3 can be flexibly adjusted. Combined with the screw mounting holes 301 on the mounting mating part 30 at the front end of the slider 3, the lens module can be installed. In this way, the installation and testing of lens modules of different sizes can be realized. It can meet the positioning and installation of lens modules with a maximum installation size of 300mm in the horizontal direction and 120mm in the vertical direction. This facilitates the work of designers, improves the efficiency of installation and testing, and has a wider range of applications.

[0033] In addition, to facilitate quick and easy adjustment, scales 8 are provided on the surface of the base plate 1 and the side of the side plate 2 in this embodiment. This allows for rapid horizontal and vertical adjustment to meet the installation requirements of the lens module, enabling quick and easy positioning and movement to the desired size, saving labor and improving efficiency.

[0034] refer to Figure 1-4As shown, taking the test lens module 9 in this embodiment as an example, first, the two side plates 2 and the four sliders 3 are aligned to the zero position, that is... Figure 1 , 2 In the current state, the horizontal distance between the four sliders 3 screw mounting holes 301 is W1, and the vertical distance is H1. The horizontal distance between the mounting holes of the lens module 9 to be installed and tested is W2, and the vertical distance is H2. Then, the two side plates 2 are slid horizontally to the left and right sides by a distance of (W2-W1) / 2, and the screws are tightened to fix the side plates 2. The four sliders 3 are slid vertically up and down by a distance of (H2-H1) / 2, and the screws are tightened to fix the sliders 2. In this way, the sliders can be quickly positioned and moved to the required size, which is convenient and fast.
