[0002] With the rapid expansion of the automotive market, especially the new energy vehicle market, the demand for vehicle-mounted camera mounts has also increased significantly. Vehicles have long service lives and experience frequent vibrations during high-speed driving, so vehicle-mounted products require extensive vibration testing during new product verification and mass production. Therefore, these products have high precision requirements. As suspension components, vehicle-mounted camera mounts need to withstand even greater vibration forces, necessitating inspection of their contours and positions after production. These dimensional inspections typically utilize gauges, employing feeler gauges or position pins to measure the mounts on the gauges. Current measurement methods often involve multiple gauges to complete different inspection items, resulting in low efficiency. Furthermore, issues such as improper storage of inspection tools and tool damage frequently occur, severely impacting product inspection accuracy and gauge maintenance costs. Utility Model Content

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1 to 7 A vehicle-mounted camera bracket inspection tool includes a base 1 and an insert 2. The insert 2 is embedded in the upper end of the base 1, and the end face of the insert 2 away from the base 1 is the same as the outline of the bracket to be inspected. When the insert 2 is damaged, it can be removed from the base 1 separately for convenient daily maintenance and replacement. The insert 2 has a positioning block 3 at the corresponding position of the outline of the bracket to be inspected. The positioning block 3 is integrally formed with the insert 2, ensuring high strength and accuracy. A first support seat 4 is provided on one side of the insert 2, and a detachable feeler gauge 5 is provided at the upper end of the first support seat 4. A second support seat 6 is provided on one side of the insert 2, and a detection pin 7 is inserted into the second support seat 6. The feeler gauge 5 and the detection pin 7 are simple to store and reliably fixed, which can prevent the inspection tools from being lost or damaged. The base 1 has handling handles 8 on both sides and foot pads 9 at the lower end of the base 1.

[0029] Furthermore, the detection pin 7 includes a cylindrical detection end 701 and a handheld end 702, wherein the detection end 701 is detachably disposed at one end of the handheld end 702; the diameter of the detection end 701 is equal to the diameter of the hole to be detected on the bracket minus its positional tolerance; the top of the second support 6 is provided with a plug hole 10, the diameter of which is slightly larger than that of the detection end 701.

[0030] Furthermore, a magnetic block 401 is provided at the top of the first support base 4, and the feeler gauge 5 is made of ferromagnetic material. When the feeler gauge 5 is not in use, it can be adsorbed onto the upper end of the first support base 4, making storage simple and convenient. The second support base 6 includes a magnetic base plate 601 and a fixing base 602 fixed on the base plate 601. The insertion hole 10 passes through the fixing base 602 and is perpendicular to the base plate 601. The detection end 701 is made of ferromagnetic material. When the detection pin 7 is not in use, it can be inserted into the fixing base 602 and magnetically attracted to the upper end of the base plate 601, which can prevent the detection pin 7 from shaking, falling off, or being worn.

[0031] Further, see Figures 4 to 5One end of the handheld end 702 is provided with a connection hole 11 for insertion into the detection end 701. A spring pin 12 is provided on one side of the inner wall of the connection hole 11. The detection end 701 is provided with a circular arc groove 13 on the side connected to the handheld end 702. After the spring pin 12 is released, the detection end 701 of the detection pin 7 can be removed from the handheld end 702, which not only reduces the cost of maintenance and replacement, but also allows for the replacement of detection ends 701 of different sizes, increasing the versatility of the detection pin 7. One side of the base plate 601 is provided with a table surface that contacts the handheld end 702. The outer wall of the handheld end 702 is provided with a recessed positioning hole 14 at the corresponding position of the spring pin 12. The inspector can identify the position of the spring pin 12 through the positioning hole 14, thereby accurately aligning the spring pin 12 with the base plate 601 and releasing the restriction of the spring pin 12 through the magnetic attraction of the base plate 601.

[0032] Furthermore, the positioning blocks 3 are arranged in an L-shape, including a first positioning block 301 disposed on one side of the bracket to be tested, and a second positioning block 302 disposed on the adjacent side of the bracket to be tested.

[0033] Further, see Figure 2 The insert 2 has an upper limit mark 15 and a lower limit mark 16 on both sides of the outline of the bracket to be inspected. The distance from the upper limit mark 15 and the lower limit mark 16 to the outline of the bracket is equal to the one-sided tolerance of the bracket outline. The inspector can intuitively and quickly confirm whether the overall outline of the bracket exceeds the upper and lower limits by using the marks. The insert 2 has a specification indicator 17 at the upper limit mark 15 and the lower limit mark 16 respectively. By using the indicator 17, the inspector can confirm whether the inspection range on the inspection tool is consistent with the product specifications, which can facilitate routine inspection and confirmation.

[0034] The working principle of this utility model:

[0035] See Figures 6 to 7During bracket inspection, first confirm the bracket outline and the upper limit mark 15 and lower limit mark 16 on the insert 2 to ensure the bracket is correctly positioned. Then, place the bracket on the insert 2, with one side of the bracket abutting against the first positioning block 301 and the adjacent side abutting against the second positioning block 302. After placing the bracket, the inspector can use the upper limit mark 15 and lower limit mark 16 to confirm whether the bracket's outline exceeds the specifications. When inspecting the outline of the bracket's end face, the inspector removes the feeler gauge 5 from the first support base 4 and inserts it into the gap between the bracket and the insert 2. The feeler gauge 5 should be able to be inserted to a certain degree. If the position of the hole on the bracket is not qualified, the other way around is qualified. When testing the position of the hole on the bracket, the tester removes the test pin 7 from the second support 6 and inserts the test pin 7 into the hole to be tested on the bracket. If the test end 701 can be inserted, it is qualified; otherwise, it is unqualified. After the test is completed, the feeler gauge 5 can be magnetically attached to the upper end of the first support 4, and the test pin 7 can be inserted into the second support 6 for fixation. When the test end 701 of the test pin 7 is damaged, the positioning hole 14 of the handheld end 702 is oriented towards the base plate 601 and in contact with the base plate 601. Then the test end 701 is removed from the handheld end 702, so that a new test end 701 can be replaced.
