Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing fixtures, specifically an inspection tool for automotive headlight beam assemblies. Background Technology

[0002] The integrated die-casting process for automotive parts is becoming increasingly mature. Traditionally, headlight crossbeam assemblies were formed by separately inspecting multiple components and then assembling the qualified parts. Current integrated die-casting processes combine the headlight crossbeam bracket and beam into a single unit. Because the bracket has holes (for bolt connections), the flatness of the end faces near these holes needs to be checked to ensure a proper fit between the nuts and the bracket surface. Simultaneously, the flatness of the bracket surface must be inspected. Existing inspection fixtures are designed for individual components and are unsuitable for effectively inspecting the entire assembly.

[0003] Therefore, it is necessary to provide a fixture for automotive headlight beam assembly. Utility Model Content

[0004] This utility model provides an inspection tool for automotive headlight crossbeam assembly, which effectively solves the problem of lack of inspection of crossbeam supports in existing crossbeam inspection.

[0005] The technical solution adopted in this utility model is: A fixture for automotive headlight beam assemblies includes a frame, and further includes several positioning components and clamping components mounted on the frame for positioning the product, a go gauge, a face inspection plate, and a movable inspection pin mounted on the frame. The movable inspection pin includes a pin and a disc mounted on the pin. The positioning components are provided with positioning holes that mate with the pin. A gap is formed between the lower end face of the disc and the product. The upper end face of the positioning components is flush with the bracket end face of a qualified product. The go gauge is used to check whether the gap is qualified. The face inspection plate is used to check whether the upper end face of the positioning components is flush with the upper end face of the product.

[0006] Furthermore, the frame is also equipped with a magnet, the face detection plate is made of magnetic metal, and the face detection plate is placed on the magnet.

[0007] Furthermore, the frame is also provided with a plastic clip for fixing the go gauge, and the plastic clip is provided with a slot for fixing the go gauge.

[0008] Furthermore, the clamping assembly includes a first-end clamping member, an end-end clamping member, and a bracket clamping member. The first-end clamping member includes a first support, a first carrier seat, a first quick clamp, and a first clamping block on the first quick clamp, all mounted on the frame. The end-end clamping member includes a second support, a side positioning plate, a second quick clamp, and a second clamping block on the second quick clamp, all mounted on the frame.

[0009] Furthermore, the bracket clamping component includes a No. 3 support mounted on the frame, a fixed block mounted on the No. 3 support, a rotating plate rotatably mounted on the fixed block, a No. 1 column and a No. 2 column slidably mounted on the rotating plate, a No. 1 positioning boss mounted on the No. 1 column, a No. 2 positioning boss mounted on the No. 2 column, a No. 1 spring sleeved on the No. 1 column, a No. 2 spring sleeved on the No. 2 column, a No. 1 limiting head mounted on the upper end of the No. 1 column, and a No. 2 limiting head mounted on the No. 2 column. The two ends of the No. 1 spring abut against the rotating plate and the No. 1 positioning boss respectively, the two ends of the No. 2 spring abut against the No. 2 positioning boss and the rotating plate respectively, and the No. 1 positioning boss abuts against the upper end face of the bracket.

[0010] Furthermore, the gauge includes a column and two detection cylinders, a first detection cylinder and a second detection cylinder, located at both ends of the column. The diameter of the first detection cylinder is larger than the diameter of the second detection cylinder. If the first detection cylinder cannot be inserted into the gap and the second detection cylinder can completely pass through the gap, then the gap is qualified.

[0011] Furthermore, the frame includes a support plate, a handle on the support plate, a frame, casters at the four corners of the lower end of the frame, support columns at the four corners of the upper end of the frame, and side baffles on the frame for lateral positioning of the support plate, wherein the support plate is supported by the support columns.

[0012] The beneficial effects of the utility model are: it can use the surface inspection plate to detect the flatness of the end face of the product bracket, and at the same time, it can use the go gauge and the movable inspection pin to detect whether the bracket surface around the product hole is flat.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a car headlight beam assembly inspection fixture includes a frame 1, and further includes several positioning components 2 and clamping components 3, a gauge 4, a surface inspection plate 5, and a movable inspection pin 6 mounted on the frame 1 for positioning the product. The movable inspection pin 6 includes a pin 61 and a disc 62 mounted on the pin 61. The positioning components 2 are provided with positioning holes that mate with the pin 61. A gap 300 is formed between the lower end face of the disc 62 and the product. The upper end face of the positioning components 2 is flush with the end face of the bracket 200 of the qualified product. The gauge 4 is used to detect whether the gap 300 is qualified. The surface inspection plate 5 is used to detect whether the upper end face of the positioning components 2 is flush with the upper end face of the product.

[0021] It should be noted that the product (automotive headlight crossbeam assembly) includes a beam 100 and a bracket 200 mounted on the beam 100. The upper surface of the positioning component 2 is flush with the upper surface of the standard bracket 200. The bracket 200 has holes. To ensure that the nuts fit snugly against the end face of the bracket 200 when the holes are assembled with bolts and nuts, it is necessary to check whether the end faces around the holes are flat (sloping planes). The lower surface of the disc 62 is a sloping flat surface. The movable detection pin 6 is not fixed to any structure.

[0022] In actual use, after positioning the product using the positioning component 2, clamping the product using the clamping component 3, then inserting the movable detection pin 6 into the through hole of the product bracket 200, so that the pin 61 extends into the positioning hole to achieve the positioning of the pin 61. At this time, the lower end of the disc 62 forms a gap 300 with the product. Then, the width dimension of the gap 300 is checked using the go gauge 4. Then, the side plane of the face detection plate 5 is held so that the side plane of the face detection plate 5 simultaneously contacts the end face of the product bracket 200 and the end face of the positioning component 2. Whether the side plane can simultaneously and completely fit with the upper end face of the bracket 200 and the upper end face of the positioning component 2, if they cannot fit simultaneously, the flatness of the upper end face of the product bracket 200 is unqualified.

[0023] In the above design, the flatness of the end face of the product bracket 200 can be detected by the surface inspection plate 5, and the surface of the bracket 200 around the product hole can be checked by the go gauge 4 and the movable inspection pin 6.

[0024] Specifically: such as Figure 1 As shown, a magnet 8 is also provided on the frame 1, and the face detection plate 5 is made of magnetic metal, such as iron. The face detection plate 5 is placed on the magnet 8.

[0025] In actual use, when it is necessary to perform a surface flatness test, the surface test plate 5 is removed from the magnet 8 for testing. After the test is completed, the surface test plate 5 is placed back on the magnet 8.

[0026] In the above design, the design of magnet 8 and the design of metal surface detection plate 5 facilitate the storage of surface detection plate 5 and facilitate quick access to surface detection plate 5.

[0027] Specifically: such as Figure 2 As shown, the frame 1 is also provided with a plastic clip 7 for fixing the go gauge 4, and the plastic clip 7 is provided with a slot for fixing the go gauge 4.

[0028] In actual use, the go gauge 4 is fixed by the slot. When the go gauge 4 needs to be taken out, it is simply taken out of the slot.

[0029] In the above design, the structural design and specific implementation of the plastic clip 7 facilitate the storage of the gauge 4.

[0030] Specifically: such as Figure 1 and Figure 2 As shown, the clamping assembly 3 includes a first-end clamping member 31, an end-end clamping member 32, and a bracket clamping member 33. The first-end clamping member 31 includes a first support 311, a first carrier 312, a first quick clamp 313, and a first clamping block 314, all mounted on the frame 1. The end-end clamping member 32 includes a second support 321, a side positioning plate 322, a second quick clamp 323, all mounted on the side of the second support 321, and a second clamping block 324, all mounted on the second quick clamp 323.

[0031] In actual use, the product is supported by positioning component 2 and support 311. Then, the first quick clamp 313 drives the first clamp block 314 to press the first end of beam 100 onto support 311. Then, the second quick clamp 323 drives the second clamp block 324 to press the end of beam 100 onto one side of support 321.

[0032] In the above design, the structural design and specific implementation of the clamping component 3 can effectively clamp the product.

[0033] Specifically: such as Figure 2 As shown, the bracket clamping component 33 includes a third support 331 mounted on the frame 1, a fixing block 332 mounted on the third support 331, a rotating plate 333 rotatably mounted on the fixing block 332, a first post 334 and a second post 335 slidably mounted on the rotating plate 333, a first positioning boss 336 mounted on the first post 334, a second positioning boss 337 mounted on the second post 335, a first spring 338 sleeved on the first post 334, a second spring 339 sleeved on the second post 335, a first limiting head mounted on the upper end of the first post 334, and a second limiting head mounted on the second post 335. The two ends of the first spring 338 abut against the rotating plate 333 and the first positioning boss 336, respectively. The two ends of the second spring 339 abut against the second positioning boss 337 and the rotating plate 333, respectively. The first positioning boss 336 abuts against the upper surface of the bracket 200.

[0034] It should be noted that a locking element is provided between the fixed block 332 and the rotating plate 333. The locking element can be inserted into the fixed block 332 and the rotating plate 333 to lock the fixed block 332 and the rotating plate 333.

[0035] In actual use, before the product is placed on the positioning component 2, the rotating plate 333 opens. When it is necessary to clamp the product using the clamping component 3 of the bracket 200, the rotating plate 333 is rotated toward the upper surface of the bracket 200, so that the lower ends of the first post 334 and the second post 335 extend into the two holes of the bracket 200 respectively. The first positioning boss 336 and the second positioning boss 337 abut against the upper surface of the bracket 200 around the two holes respectively. During this process, since the rotating plate 333 has not yet reached the predetermined angle, the first spring 338 and the second spring 339 will be compressed until the rotating plate 333 rotates to the predetermined position, and then the locking component locks the fixing block 332 to the rotating plate 333.

[0036] In the above design, the structural design and specific implementation of the bracket clamping member 33 can effectively achieve the clamping of the bracket 200, and the first spring 338 and the second spring 339 are used to buffer the bracket 200 during clamping.

[0037] Specifically: such as Figure 4 As shown, the gauge 4 includes a column 41 and a first detection cylinder 42 and a second detection cylinder 43 disposed at both ends of the column 41. The diameter of the first detection cylinder 42 is larger than the diameter of the second detection cylinder 43. If the first detection cylinder 42 cannot be inserted into the gap 300 and the second detection cylinder 43 can completely pass through the gap 300, then the gap 300 is qualified.

[0038] In actual use, when gap 300 needs to be tested, hold the cylinder 41, first use the first testing cylinder 42 to insert into the gap 300 for testing, and then use the second testing cylinder 43 to insert into the gap 300 for testing. If the first testing cylinder 42 cannot be inserted into the gap 300 and the second testing cylinder 43 can completely pass through the gap 300, then the gap 300 is qualified; otherwise, it is unqualified.

[0039] In the above design, the structural design and specific implementation of the gauge 4 enable rapid detection of the gap 300.

[0040] Specifically: such as Figure 1 As shown, the frame 1 includes a support plate 11, a handle 12 disposed on the support plate 11, a frame 13, casters 14 disposed at the four corners of the lower end of the frame 13, support columns disposed at the four corners of the upper end of the frame 13, and side baffles 15 disposed on the frame 13 for laterally limiting the support plate 11. The support plate 11 is supported by the support columns.

[0041] In actual use, the frame 13 is pushed so that the casters 14 move the entire frame 1. When the support plate 11 needs to be replaced, the handle 12 is held to remove the support plate 11 from the support column. The support plate 11 is circumferentially positioned by the side baffle 15.

[0042] In the above design, the structural design and specific implementation of the frame 1 facilitate the movement of the entire inspection fixture and the replacement of the support plate 11.

[0043] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
