In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] like Figures 1 to 3 As shown, this utility model provides a product testing fixture. Some specific embodiments are described below, including a support plate 1. The support plate 1 is used to install a fixing and positioning device 2, a longitudinal detection device 3, and an oblique detection device 4. The positioning device 2 is used to fix the product, which facilitates fixing the position of the product and makes it easier for subsequent testing.

[0035] In some embodiments, a plurality of positioning devices 2 are installed on the support plate 1 to prevent the product from shaking on the support plate 1. The plurality of positioning devices 2 can ensure that the position of the product is uniquely determined, and the position and angle of the product remain unchanged after each product change. The positioning device 2 includes a positioning post 201 installed on the support plate 1 and a first quick clamp 202 that cooperates with the positioning post 201.

[0036] In some embodiments, the positioning post 201 is mounted on the support plate 1 via a fixing plate 205. The positioning post 201 is vertically upward and is used to insert into the longitudinal hole of the product for positioning. The clamping end of the first quick clamp 202 is movably connected to a first pressing arm 203. The end of the first pressing arm 203 is provided with a first clearance groove 204, which can accommodate the top of the positioning post 201. In use, after the product is inserted into the positioning post 201, the first quick clamp 202 presses down the first pressing arm 203, so that the upper end of the positioning post 201 passes into the first clearance groove 204. The first pressing arm 203 presses down and fixes the product at the periphery of the positioning post 201.

[0037] A longitudinal detection device 3 is installed on the support plate 1. The longitudinal detection device 3 is used to detect whether the position and angle of the longitudinal hole to be tested are qualified. The longitudinal detection device 3 includes a detection plate 301 installed on the support plate 1, a second quick clamp 302 and a detection pin 303 that cooperate with the detection plate 301. The clamping end of the second quick clamp 302 is movably connected to a second pressing arm 304, and the end of the second pressing arm 304 is provided with a second clearance groove 305. A positioning hole 306 is provided on the detection plate 301, and the detection pin 303 can pass through the second clearance groove 305 and enter the positioning hole 306.

[0038] In use, the second quick clamp 302 is used to press down the second pressing arm 304, so that the second clearance groove 305 is above the longitudinal hole to be tested. The test pin 303 is then passed through the second clearance groove 305 and enters the longitudinal hole to be tested to reach the positioning hole 306. If the test pin 303 can successfully reach the positioning hole 306, it means that the longitudinal hole to be tested at that position of the product is qualified; otherwise, it is unqualified.

[0039] An oblique detection device 4 is installed on the support plate 1. The oblique detection device 4 is used to detect whether the position and angle of the oblique test hole are qualified. The oblique detection device 4 includes a support member 401, which is fixedly installed on the support plate 1. The top of the support member 401 is provided with a bending part 402. Multiple detection rods 403 are slidably installed on the bending part 402, so that the detection rods 403 can extend and retract on the bending part 402. The sliding installation method is a conventional technical means and will not be described in detail here.

[0040] Multiple detection rods 403 each have an enlarged head 404 at one end, and a spring 405 is fitted between the enlarged head 404 and the bent portion 402, so that after the detection rod 403 is extended obliquely downwards, it can be reset by the reaction force of the spring 405. In this specific embodiment, the angle between the bent portion and the support member 401 is an obtuse angle, so that the detection rod 403 is directly facing the oblique hole to be tested. In use, the other end of the detection rod 403 is inserted into the oblique hole to be tested by pressing the detection rod 403. If it can be smoothly inserted into the oblique hole to be tested, it means that the oblique hole to be tested is qualified; otherwise, it is unqualified.

[0041] More specifically, there are multiple detection rods 403, and their diameters are at least partially different, used to detect oblique holes of different diameters. In this specific embodiment, there are two detection rods 403, and the two detection rods 403 correspond to two oblique holes of different diameters, with one large and one small diameter matching the diameters of the corresponding two oblique holes of different diameters.

[0042] In some other specific embodiments, the first quick clamp 202 includes a first base 2021, a first hand arm 2022, a first movable arm 2023, and a first connecting arm 2024. The first base 2021 is mounted on the support plate 1. The first hand arm 2022 and the first movable arm 2023 are both hinged to the first base 2021. The two ends of the first connecting arm 2024 are respectively hinged to the first hand arm 2022 and the first movable arm 2023. The first hand arm 2022 can drive the first movable arm 2023 to perform downward or upward movements through the first connecting arm 2024.

[0043] The first pressing arm 203 is movably connected to the first movable arm 2023. Specifically, the first movable arm 2023 is provided with a first strip hole 2025. The first pressing arm 203 is connected to the first movable arm 2023 by two bolts passing through the first strip hole 2025. By adjusting the installation position of the two bolts in the first strip hole 2025, the installation position of the first pressing arm 203 on the first movable arm 2023 can be adjusted, thereby adjusting the extension length of the first pressing arm 203. This ensures that the first clearance groove 204 of the first pressing arm 203 is aligned with the positioning post 201, so that the two sides of the first clearance groove 204 can press down and fix the product located on the periphery of the positioning post 201.

[0044] The second quick clamp 302 includes a second base 3021, a second hand arm 3022, a second movable arm 3023, and a second connecting arm 3024. The second base 3021 is mounted on the support plate 1. The second hand arm 3022 and the second movable arm 3023 are both hinged to the second base 3021. The two ends of the second connecting arm 3024 are respectively hinged to the second hand arm 3022 and the second movable arm 3023. The second hand arm 3022 can drive the second movable arm 3023 to perform downward or upward movements through the second connecting arm 3024.

[0045] The second pressing arm 304 is movably connected to the second movable arm 3023. The second movable arm 3023 is provided with a second strip hole 3025. The second pressing arm 304 is connected to the second movable arm 3023 by multiple bolts passing through the second strip hole 3025. By adjusting the installation position of the two bolts in the second strip hole 3025, the installation position of the second pressing arm 304 on the second movable arm 3023 can be adjusted, thereby adjusting the extension length of the second pressing arm 304. This ensures that the second relief groove 305 of the second pressing arm 304 is directly aligned with the longitudinal hole to be inspected, so that both sides of the second relief groove 305 can press down on the periphery of the longitudinal hole to be inspected, ensuring a more stable product position and facilitating inspection.

[0046] In addition, to improve the convenience of the support plate 1, a support block 5 is installed under the support plate 1, allowing the support plate 1 to be placed on a workbench. A handle 6 is installed on the side of the support plate 1 for easy repositioning.

[0047] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
