Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to a novel car bracket inspection tool. Background Technology

[0002] With the continuous expansion of the automotive market, especially the rapid growth of the new energy vehicle market, the demand for windshield brackets for cars is also increasing rapidly. Windshield brackets are generally located above the center of the windshield, with one side contacting the windshield and the other side housing a camera, switch buttons, and a cover. Due to the large number of components assembled with the windshield bracket, and the constant vibrations experienced by the car during high-speed operation, the precision requirements for the windshield bracket are high. Currently, after production, windshield brackets require detailed contour inspection, including size, hole size, and the relative position of end faces. This requires different inspection tools, and currently, switching between different fixtures is often time-consuming, inefficient, and prone to causing secondary damage to the windshield bracket. Go-stop blocks are suitable for inspecting the contour of lateral holes, but they are easily damaged or lost during normal storage, affecting inspection accuracy and the cost of using the fixtures. Utility Model Content

[0003] This utility model relates to a novel car bracket inspection tool. The entire tool has a simple structure, accurate and reliable testing, and the parts that frequently come into contact with the bracket can be replaced individually, reducing usage costs. The stop block has excellent strength and is not easily tipped over when stored in the storage box, preventing damage from impacts or friction and significantly extending its service life. The testing range markings have a prompting and error-proof function, improving testing efficiency and accuracy. The feeler gauge can be magnetically attached to the upper end of the bracket, making it convenient and reliable to store and less likely to be lost.

[0004] The technical solution of this utility model is as follows:

[0005] A novel car bracket inspection tool includes a base and an insert disposed on the upper end of the base. The top end face of the insert is identical to the contour of the bracket to be inspected. The insert has a positioning block at the edge of the side contour of the bracket to be inspected. The base has a support on one side of the insert, and a detachable feeler gauge is disposed at the upper end of the support. The base has a storage box on the other side of the insert, and a stop block is disposed inside the storage box. The base has handles on both sides and support feet at the bottom.

[0006] The stop block includes a through end, a stop end, and a handheld end arranged in a straight line, which are integrally formed; the through end is slightly smaller than the hole to be tested on the bracket, and the stop end is slightly larger than the hole to be tested on the bracket.

[0007] Wherein, the radial cross-sectional dimension of the handheld end is larger than that of the stop end, and the sum of the lengths of the through end and the stop end is smaller than that of the handheld end.

[0008] The end face of the through end that is furthest from the stop end has the same bottom morphology as the hole to be tested on the bracket.

[0009] The positioning block includes a first positioning block, a second positioning block, and a third positioning block, which are integrally formed with the insert; the first positioning block and the second positioning block are located on the same side of the bracket to be tested, and the first positioning block, the second positioning block, and the third positioning block are arranged in an L-shape.

[0010] The distance between the first positioning block and the second positioning block is less than the side profile length of the bracket to be tested and greater than or equal to 1 / 2 of the side profile length.

[0011] The ends of the first, second, and third positioning blocks near the bracket to be tested are provided with rounded corners.

[0012] The feeler gauge is magnetically attached to the upper end of the support.

[0013] The insert has a detection range mark at the detection position of the feeler gauge.

[0014] The surface of the insert is provided with an upper limit profile line and a lower limit profile line, and the distance from the upper limit profile line and the lower limit profile line to the bracket profile is equal to the one-sided tolerance of the bracket profile.

[0015] This utility model has the following beneficial effects:

[0016] 1. Compared with the original car bracket inspection tool, the present invention has a simple structure and accurate and reliable inspection; the outline of the side hole can be detected by the stop block. The stop block has good strength and is not easy to tip over when stored in the storage box, which can avoid the stop block being damaged by impact or friction, and the service life is significantly improved.

[0017] 2. The first positioning block, the second positioning block and the third positioning block of this utility model are integrally formed with the insert, which has better strength, is not easy to deform, and ensures the detection accuracy. The distance between the first positioning block and the second positioning block is less than the side contour length of the bracket to be tested and greater than or equal to 1 / 2 of the side contour length, which can prevent the bracket from tilting to one side when it is in place and ensure the alignment accuracy of the bracket.

[0018] 3. The ends of the first positioning block, the second positioning block and the third positioning block of this utility model are provided with rounded corners. The rounded corners can enhance the deformation resistance of the corners of the positioning blocks and prevent corner impacts from causing bulging, which would affect the positioning of the bracket. At the same time, the rounded corners can significantly reduce the contact area at the ends and reduce the risk of misalignment caused by foreign objects remaining at the ends.

[0019] 4. As a component that frequently comes into contact with the bracket, the insert of this utility model can be disassembled, repaired and replaced separately, which can reduce the cost of use; as a positioning and support component, the insert requires additional anodizing and sandblasting treatment. Separate production and processing of the insert can not only reduce material costs, but also ensure processing accuracy.

[0020] 5. The detection range markings of this utility model have a prompting and error-proof function. Operators can quickly find the position to be detected by the detection range markings, thus improving detection efficiency. In addition, when the feeler gauge is inserted for detection, it must be located within the detection range markings to avoid detection errors caused by feeler gauge misalignment.

[0021] 6. The feeler gauge of this utility model can be magnetically attached to the upper end of the support, so it does not need to be placed in a separate storage box. It is convenient and reliable to store and is not easy to lose. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] See Figures 1 to 5 A novel car bracket inspection fixture includes a base 1 and an insert 2 disposed on the upper end of the base 1. The car brackets listed in this embodiment are as follows: Figure 2As shown, it includes a side hole 13; the top end face of the insert 2 is the same as the outline of the bracket to be tested, and the insert 2 is provided with a positioning block 3 at the edge of the side outline of the bracket to be tested; the base 1 is provided with a support 4 on one side of the insert 2, and a detachable feeler gauge 5 is provided at the upper end of the support 4; the base 1 is provided with a storage box 6 on the other side of the insert 2, and a stop block 7 is provided in the storage box 6. The outline of the side hole 13 of the bracket can be detected by the stop block 7. The stop block 7 is not easy to tip over when stored in the storage box 6, and can avoid the stop block 7 from being damaged by impact or friction; the base 1 is provided with handles 8 on both sides, and the base 1 is provided with support feet 9 at the bottom. The support feet 9 are preferably made of rubber, which has a good cushioning effect.

[0031] Further, see Figure 5 The stop block 7 includes a through end 701, a stop end 702, and a handle end 703 arranged in a straight line. The through end 701, stop end 702, and handle end 703 are integrally formed, giving the stop block 7 good strength and preventing deformation during use. The through end 701 is slightly smaller than the inspection hole on the bracket, and the stop end 702 is slightly larger than the inspection hole on the bracket. The radial cross-sectional dimension of the handle end 703 is larger than that of the stop end 702. The through end 701 and the stop end... The sum of the lengths of 702 and 703 is less than that of the handheld end 703. When the stop block 7 is placed in the storage box 6, the weight of the handheld end 703 is greater than that of the through end 701 and the stop end 702, which can ensure that the through end 701 and the stop end 702 are suspended in the air, thus avoiding damage to the through end 701 and the stop end 702 from impact and friction. The end face of the through end 701 that is away from the stop end 702 has the same bottom morphology as the hole to be tested on the bracket. In this way, the through end 701 can penetrate as deeply as possible into the side hole 13, thereby improving the detection range.

[0032] Furthermore, the positioning block 3 includes a first positioning block 301, a second positioning block 302, and a third positioning block 303. The first positioning block 301, the second positioning block 302, and the third positioning block 303 are integrally formed with the insert 2, resulting in better strength, less deformation, and guaranteed detection accuracy. The first positioning block 301 and the second positioning block 302 are located on the same side of the bracket to be tested, and the first positioning block 301, the second positioning block 302, and the third positioning block 303 are arranged in an L-shape. The first positioning block 301 and the second positioning block 302... The spacing of 302 is less than the side profile length of the bracket to be tested and greater than or equal to 1 / 2 of the side profile length. The wider spacing can prevent the bracket from tilting to one side when it is in place, and can ensure the positioning accuracy of the bracket. The ends of the first positioning block 301, the second positioning block 302 and the third positioning block 303 near the bracket to be tested are provided with rounded corners. The rounded corners can enhance the deformation resistance of the corners of the positioning blocks 3, prevent corner impacts from causing bulging, and affect the positioning of the bracket. At the same time, the rounded corners can significantly reduce the contact area at the ends, reducing the risk of misalignment caused by foreign objects remaining at the ends.

[0033] Furthermore, the feeler gauge 5 is magnetically attached to the upper end of the support 4, so the feeler gauge 5 does not need to be placed in a separate storage box, making storage convenient and reliable, and less likely to be lost.

[0034] Furthermore, insert 2, as a positioning and support component, requires additional anodizing and sandblasting treatment. When insert 2 is damaged, it can be disassembled and replaced separately, reducing usage costs. In addition, separately manufacturing insert 2 not only reduces material costs but also ensures machining accuracy. Insert 2 has a detection range mark 10 at the detection position of feeler gauge 5. The detection range mark 10 has a prompting and error-proofing function, allowing operators to quickly locate the position to be tested. In addition, when feeler gauge 5 is inserted for testing, it must be within the detection range mark 10 to avoid detection errors caused by feeler gauge 5 misalignment. The surface of insert 2 is provided with an upper limit contour line 11 and a lower limit contour line 12. The distance from the upper limit contour line 11 and the lower limit contour line 12 to the bracket contour is equal to the one-sided tolerance of the bracket contour.

[0035] The working principle of this utility model:

[0036] See Figure 2 During bracket testing, the bracket is first placed on insert 2, with one side of the bracket abutting against the first positioning block 301 and the second positioning block 302, and the other adjacent side of the bracket abutting against the third positioning block 303. After positioning the bracket, the overall outline of the bracket is checked by passing the upper limit outline 11 and the lower limit outline 12. The outer edge of the bracket must fall between the upper limit outline 11 and the lower limit outline 12. When checking the outline of the bracket end face, the test range mark 10 is first located, and then the distance from the bracket to insert 2 is measured with feeler gauge 5. If the feeler gauge 5 does not pass through, it is qualified; otherwise, it is unqualified. When checking the outline of the side hole 13 of the bracket, the handheld end 703 of the stop block 7 is held for testing. If the through end 701 can be inserted and the stop end 702 cannot be inserted, it is qualified; otherwise, it is unqualified. After the test is completed, the stop block 7 is stored in the storage box 6, and the feeler gauge 5 is attached to the upper end of the support 4.
