Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a backlight testing fixture for automotive parts. Background Technology

[0002] Backlight testing of automotive components is a testing method used to evaluate the quality of interior and exterior lighting components in automobiles, ensuring the visibility and functionality of these components in actual use. This test is particularly suitable for backlit parts such as dashboards, control panels, door trim panels, and center consoles.

[0003] The existing announcement number CN213665706U, entitled "A Backlight Testing Fixture for Automotive Parts," includes horizontal guide rails, scales, vertical supports, L-shaped guide rails, a horizontal support, a fixing plate, and L-shaped clamps. Two scales are mounted on the two horizontal guide rails, and two vertical supports are installed on the two guide rails, perpendicular to them. Two L-shaped guide rails are vertically mounted within the two vertical supports, with their front ends positioned within the horizontal supports. A fixing plate is mounted at the other end of the horizontal support, and each fixing plate has four L-shaped clamps, which can easily clamp and fix parts of various shapes. Combined with the scales on the guide rails, the distance between the sample and the test lens can be adjusted to accurately fix the sample in the required position before backlight testing, obtaining relatively accurate backlight parameters. It features a simple structure, accuracy, high efficiency, and strong versatility.

[0004] However, the aforementioned automotive parts backlight testing fixture uses an L-shaped clamp to squeeze and hold automotive parts for backlight testing. However, the clamping spacing and clamping range of the L-shaped clamp are limited. The automotive parts to be tested have diverse shapes, which makes it impossible to adjust the clamping position according to the actual shape of the automotive parts later, affecting the clamping requirements and range of different types of automotive parts. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a backlight testing fixture for automotive parts.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a backlight testing fixture for automotive parts, including a slide, a translation component, and a pressing component. The slide has horizontally opened slide tracks on both sides, and the bottom end of the slide is fixedly assembled by fixing screws. Translation components are provided on both sides of the slide, and a pressing component is vertically arranged at the end of each translation component. Each translation component includes a horizontal plate, one end of which is fixed with a slider, which is horizontally slidably assembled in the slide track of the slide. A pull-out frame is horizontally fixed at the other end of the horizontal plate. The pressing component includes a slide frame, a perforated strip, and a sliding hole block. The slide frame is vertically arranged above the slide, and a perforated strip is horizontally fixed at the bottom end of the slide frame. The perforated strip is horizontally slidably assembled in the pull-out frame. The sliding hole block is vertically slidably assembled in the slide frame, and a pressing rod is horizontally slidably assembled through the sliding hole block. A rubber block is horizontally fixed at one end of the pressing rod, and a third spring is horizontally sleeved on the outside of the pressing rod, with both ends of the third spring fixed to the end of the pressing rod and the sliding hole block, respectively.

[0007] As a preferred embodiment, scale strips are horizontally fixed on both sides of the top surface of the carriage, and multiple perforated plates are vertically fixed on the outer side of the scale strips along the horizontal direction.

[0008] As a preferred embodiment, an indicator plate is fixed to the top of the outer vertical end face of the slider, and a hole block is horizontally fixed to the outer vertical end face of the slider, with a lifting rod vertically sliding through the hole block.

[0009] As a preferred embodiment, a first spring is vertically sleeved on the outside of the lifting rod, with the two ends of the first spring fixed to the end of the lifting rod and the hole block, respectively, and the top end of the lifting rod inserted into the hole plate.

[0010] As a preferred embodiment, a positioning rod is vertically inserted through the top surface of the pull-out frame, and a second spring is vertically sleeved on the outside of the positioning rod, with the two ends of the second spring fixed to the end of the positioning rod and the top surface of the pull-out frame, respectively.

[0011] As a preferred embodiment, the perforated strip has multiple slots that run horizontally and vertically through it, and the slots on the perforated strip are engaged with the positioning rod.

[0012] As a preferred embodiment, an adjusting screw is installed on the top surface of the sliding frame with a vertical thread, and the bottom end of the adjusting screw is rotatably connected to the top surface of the sliding block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When conducting backlight testing on automotive parts, depending on the shape and structure of the automotive parts to be tested, the horizontal plate on the transverse translation component moves laterally on both sides of the slide to adjust the clamping position of the automotive parts in the X-axis direction. Then, the hole strip on the pressure component is pulled laterally in the pull-out frame to adjust the clamping position of the automotive parts in the Y-axis direction. Then, the vertical adjustment sliding block moves vertically in the slide frame to adjust the clamping position of the automotive parts in the Z-axis direction. Finally, the pressure rod moves horizontally in the sliding block to squeeze and clamp the automotive parts to maintain stability. Thus, it is possible to squeeze and clamp the automotive parts to maintain stability according to the actual shape of the automotive parts, expanding the clamping requirements and scope for backlight testing of different types of automotive parts.

[0026] like Figures 1 to 5As shown, a backlight testing fixture for automotive parts includes a slide 1, a translation component 2, and a pressing component 3. The slide 1 has horizontally opened slide tracks on both sides, and its bottom end is fixedly assembled by fixing screws 13. Translation components 2 are provided on both sides of the slide 1, and a pressing component 3 is vertically arranged at the end of each translation component 2. The translation component 2 includes a horizontal plate 21, with a slider 22 fixed to one end of the horizontal plate 21. The slider 22 is horizontally slidably assembled in the slide track of the slide 1. The other end is horizontally fixed with a pull-out frame 23. The pressing component 3 includes a sliding frame 31, a perforated strip 32, and a sliding block 34. The sliding frame 31 is vertically arranged above the slide frame 1, and the bottom end of the sliding frame 31 is horizontally fixed with a perforated strip 32. The perforated strip 32 is horizontally slidably assembled in the pull-out frame 23. The sliding block 34 is vertically slidably assembled in the sliding frame 31, and a pressing rod 35 is horizontally slidably assembled through the sliding block 34. One end of the pressing rod 35 is horizontally fixed with a rubber block 352, and the pressing rod 35... A third spring 351 is horizontally sleeved on the outside of component 5, and the two ends of the third spring 351 are fixed to the end of the pressure rod 35 and the sliding block 34, respectively. During the backlight test of automotive parts, depending on the shape and structure of the automotive parts to be tested, the horizontal plate 21 on the transverse translation component 2 moves laterally on both sides of the slide 1 to adjust the clamping position of the automotive parts in the X-axis direction. Then, the hole strip 32 on the pressure rod 3 is pulled to move laterally in the pull-out frame 23 to adjust the clamping position of the automotive parts in the Y-axis direction. Then, the sliding block 34 is vertically adjusted to move vertically in the slide frame 31 to adjust the clamping position of the automotive parts in the Z-axis direction. Then, the pressure rod 35 moves horizontally in the sliding block 34 to squeeze and clamp the automotive parts to keep them stable. This allows for the squeezing and clamping of automotive parts to keep them stable according to the actual shape of the automotive parts, expanding the clamping requirements and range for backlight testing of different types of automotive parts.

[0027] In one embodiment, such as Figure 3 and 4As shown, scale bars 11 are horizontally fixed on both sides of the top surface of the slide 1, and multiple perforated plates 12 are vertically fixed on the outer side of the scale bars 11 along the horizontal direction. An indicator plate 221 is fixed to the top of the outer vertical end face of the slider 22, and a perforated block 222 is horizontally fixed on the outer vertical end face of the slider 22. A lifting rod 223 is vertically slidably inserted into the perforated block 222. A first spring 224 is vertically sleeved on the outside of the lifting rod 223. The two ends of the first spring 224 are respectively fixed to the end of the lifting rod 223 and the perforated block 222. The top end of the lifting rod 223 is inserted into the perforated plate 12. During use, the horizontal plate 21 on the transverse translation component 2 is on the slide 1. When the horizontal movement adjusts the clamping position of the car parts in the X-axis direction, the lifting rod 223 is pulled vertically in the hole block 222, causing the top of the lifting rod 223 to be pulled out of the hole plate 12. Then, the slider 22 slides in the slide rails on both sides of the slide 1. According to the scale bar 11 indicated by the indicator plate 221, the lifting rod 223 is released. Under the deformation force of the first spring 224, the top of the lifting rod 223 is pushed into the hole plate 12, limiting and maintaining the position of the translation member 2 on the slide 1. The horizontal plate 21 on the translation member 2 moves horizontally on both sides of the slide 1, adjusting the clamping position of the car parts in the X-axis direction.

[0028] In one embodiment, such as Figure 4 and 5 As shown, a positioning rod 24 is vertically inserted through the top surface of the pull-out frame 23, and a second spring 25 is vertically sleeved on the outside of the positioning rod 24. The two ends of the second spring 25 are respectively fixed to the end of the positioning rod 24 and the top surface of the pull-out frame 23. Multiple slots are vertically and horizontally inserted through the perforated strip 32, and the slots on the perforated strip 32 are engaged with the positioning rod 24. In use, pulling the positioning rod 24 on the pull-out frame 23 moves vertically, causing the second spring 25 to deform. Then, pulling the perforated strip 32 on the pulling abutment 3 moves horizontally in the pull-out frame 23. When the positioning rod 24 is released, under the deformation force of the second spring 25, the positioning rod 24 is pushed into the slot on the perforated strip 32, and the horizontal movement adjusts the clamping position of the car parts in the Y-axis direction.

[0029] In one embodiment, such as Figure 5 As shown, an adjusting screw 33 is vertically threaded through the top surface of the slide frame 31, and the bottom end of the adjusting screw 33 is rotatably connected to the top surface of the sliding hole block 34. During use, the vertical adjustment sliding hole block 34 moves vertically in the slide frame 31. Rotating the adjusting screw 33 on the top surface of the slide frame 31 moves vertically, pushing the sliding hole block 34 to move vertically in the slide frame 31, adjusting the clamping position of the car parts in the Z-axis direction.

[0030] In this embodiment, during backlight testing of automotive parts, depending on the shape and structure of the automotive parts to be tested, the horizontal plate 21 on the transverse translation component 2 moves laterally on both sides of the slide 1. When adjusting the clamping position of the automotive parts in the X-axis direction, the lifting rod 223 is pulled vertically in the hole block 222, causing the top of the lifting rod 223 to be pulled out of the hole plate 12. Then, the slider 22 moves in the slide rails on both sides of the slide 1. According to the scale bar 11 indicated by the indicator plate 221, the lifting rod 223 is released. Under the deformation force of the first spring 224, the top of the lifting rod 223 is pushed into the hole plate 12, limiting and maintaining the position of the translation component 2 on the slide 1. The horizontal plate 21 on the transverse translation component 2 moves laterally on both sides of the slide 1, adjusting the clamping position of the automotive parts in the X-axis direction. Then, the lifting rod 223 is pulled vertically in the hole block 222, causing the top of the lifting rod 223 to be pushed into the hole plate 12. The perforated strip 32 on the pressing component 3 moves laterally within the pull-out frame 23, pulling the positioning rod 24 on the pull-out frame 23 to move vertically, causing the second spring 25 to deform. Then, the perforated strip 32 on the pressing component 3 moves laterally within the pull-out frame 23. The positioning rod 24 is released, and under the deformation force of the second spring 25, it is pushed into the slot on the perforated strip 32. This lateral movement adjusts the clamping position of the automotive parts in the Y-axis direction. Then, the sliding block 34 is vertically adjusted within the sliding frame 31. The adjusting screw 33 on the top surface of the sliding frame 31 is rotated vertically, pushing the sliding block 34 to move vertically within the sliding frame 31, adjusting the clamping position of the automotive parts in the Z-axis direction. Finally, the pressing rod 35 moves horizontally within the sliding block 34, squeezing and clamping the automotive parts to maintain stability.

[0031] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
