Description
Technical Field
[0001] This invention relates to the field of automotive parts inspection, and specifically to an inspection tool suitable for general automotive information main units. Background Technology
[0002] In the field of automotive electronic system integration, the general information host, as the core terminal for vehicle function control, directly affects equipment stability and overall vehicle assembly quality through its installation accuracy. However, the following technical problems exist in the actual assembly process:
[0003] Due to differences in dashboard structures across different vehicle models, universal head units often encounter issues such as misalignment of mounting holes and bracket failure during cross-platform adaptation. Existing solutions rely on manual adjustments, leading to the need for re-drilling holes or replacing custom brackets, resulting in high rates of rework in batches.
[0004] The current testing method involves using go / no-go gauges to individually test each mounting hole and using calipers to measure the thickness of the relevant brackets. Due to the large number of batches, the testing is cumbersome, time-consuming, labor-intensive, and inefficient.
[0005] In summary, a fixture suitable for general automotive information hosts is proposed to solve the problems mentioned in the background art. Summary of the Invention

By setting a hole position detection device and a bracket thickness detection device, the tooling can perform batch inspection of general information main units, which is convenient, fast and improves work efficiency.
[0007] A fixture for a universal automotive information host includes a mounting base plate with a positioning block on the mounting base plate. The positioning block has a mounting groove that matches the mounting surface protrusion of the universal information host. The mounting base plate also includes a clamping device and a detection device. The clamping device is located to the side of the universal information host where there is no detection position, and the detection device is located to the side of the universal information host where there is a detection position and performs detection on the universal information host.

The first and second detection devices are located on the right side of the general-purpose information host, and the third and fourth detection devices are located on the left side of the general-purpose information host.
[0011] Further specifying, the detection device includes a detection base and detection components. The detection base is detachably mounted on the mounting base plate. The detection components of the first, second, and third detection devices are all pins. The pins are mounted on the detection base. The right end of the pin is provided with a handle, and the left end is provided with a detection head. The size of the detection head matches the size of the hole to be tested.

Detailed Implementation
[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Example:
[0022] like Figures 1-3As shown, a gauge suitable for a universal automotive information host includes a mounting base plate 1, a positioning block 2 on the mounting base plate 1, and a mounting groove 4 on the positioning block 2 that matches the protrusion 3 on the mounting surface of the universal information host 9. The mounting base plate 1 is equipped with a clamping device and a detection device. The clamping device includes a first clamp 5, a second clamp 6, a main limiting block 7, and a side limiting block 8. The first clamp 5 and the second clamp 6 are located at the rear end face and left end face of the universal information host 9, respectively. The main limiting block 7 and the side limiting block 8 are located at the front end face and right end face of the positioning block 2, respectively. When the first clamp 5 clamps, it presses against... The rear end face of the general-purpose information host 9 is positioned, and the front end face of the general-purpose information host 9 abuts against the main limiting block 7 for limiting. When the second clamp 6 is clamped, it abuts against the left end face of the general-purpose information host 9, and the right end face of the general-purpose information host 9 abuts against the column-side limiting block 8. There are four detection devices, including a detection base 14 and a detection component 15, namely a first detection device 10, a second detection device 11, a third detection device 12, and a fourth detection device 13. The first detection device 10, the second detection device 11, and the third detection device 12 are all hole position detection devices, and the fourth detection device 13 is a bracket thickness detection device. The first detection device 10 and the second detection device 11 are located on the right side of the general-purpose information host 9, and the third detection device 12 and the fourth detection device 13 are located on the left side of the general-purpose information host 9. The detection base 14 is detachably mounted on the mounting base plate 1. The detection components 15 of the first detection device 10, the second detection device 11, and the third detection device 12 are all pins. The detection base 14 is provided with through holes, and the pins are mounted on the detection base 14 through the through holes. The right end of the pin is provided with a handle, and the left end is provided with a detection head. The size of the detection head matches the size of the hole to be tested. During testing, it is pushed by hand. The fourth testing device 13 uses a chuck as its testing component. The chuck's testing area has a slot 16, the width of which matches the thickness of the bracket to be tested. During testing, if the chuck's slot can hold the bracket, it indicates that the bracket's thickness is acceptable. The mounting base 1 also has a universal no-go gauge mounting seat 17, which contains go and no-go gauges. The mounting base 1 also has two handles 18 and three reference blocks 19. The two handles 18 are installed on the left and right sides of the mounting base 1, facilitating the lifting and movement of the inspection fixture.
[0023] In use, first use go / no-go gauges to check the size of the through holes of the test bases of the first test device 10, the second test device 11, and the third test device 12. If the go gauge passes through but the no-go gauge does not, it is considered qualified; otherwise, it is considered unqualified. After the test, place the go / no-go gauges on the go / no-go gauge mounting base 17, open the first clamp 5, the second clamp 6, and all the test components 15, clean the information universal host 9, align the protrusion 3 on the mounting surface with the mounting groove 4 of the mounting block 2, and then tighten the first clamp 5 and the second clamp 6. After tightening, perform the test by checking the hole position and thickness to check the test items of the information universal host 9.
[0024] The upper planes and hole centers of the three reference blocks 19 are used as the inspection references for the fixture, and the surface quality requirement is Ra0.8. The tolerance requirements for the reference surface are ±0.05mm, the positional tolerance of the reference hole is ±0.03mm, the relative positional tolerance of the reference hole is ±0.03mm, and the parallelism and perpendicularity of the reference surface are <0.05 / 1000. At the same time, during acceptance, the construction surfaces and lines of the three reference blocks can also be used, and the coordinate system of the fixture can be established by rotating and repositioning one of them as the reference point.
