The words "first", "second" and similar words used in the specification and claims of the utility model patent application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not necessarily indicate quantity restrictions. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0031] The utility model provides a U-shaped part gap measuring device, which is used in the parts gap measuring process. The utility model does not limit the type of the U-shaped part, but the structure of the U-shaped part gap measuring device is particularly suitable for measuring the internal gap or height of the U-shaped part.

[0032] In general, the U-shaped gap measuring device proposed in the present invention mainly includes a base 1, a support base 2, and a clamp unit. Figure 1 , which shows the arrangement relationship among the base 1, the support base 2 and the clamping unit.

[0033] In order to achieve the purpose of one-time rapid measurement of U-shaped parts, the problem in the background technology that the U-shaped parts are complex in shape, especially those located in the internal position that are difficult to directly observe and detect, and need to be disassembled or turned over, and the internal gap is not easy to measure directly, and some special tools are needed for measurement. However, the existing manual tool structure is not clever enough and has poor flexibility. In order to obtain accurate results, multiple measurements are required, but this may have a certain impact on the use of U-shaped parts, and also cause errors in the measurement results. For this reason, in the technical solution provided in this embodiment, the support seat 2 and the go / no-go gauge 7 are used on the base 1 to measure the gap position of the product. At the same time, the clamping effect of the spacing clamp 4 ensures the stability of the product to be tested during the detection process, as well as the position accuracy, effectively achieving one-time measurement and ensuring the accuracy of the measurement results without damaging the product.

[0034] like Figure 1 As shown, a support seat 2 for placing the product to be tested is installed on the base 1. Since the product is U-shaped and the middle position needs to be measured, only the structures at both ends can be used to achieve support and serve as a reference. Therefore, the support seat 2 is arranged in an inverted T-shaped structure, including a horizontal end and a vertical end 6 located on the central axis of the horizontal end, wherein a mounting table 3 is formed on the horizontal end to support the two ends of the bottom of the product to be tested, and the middle vertical end 6 is arranged below the middle position of the product to be tested, and chamfers 9 are arranged around the top of the vertical end 6. The installation can protect the inner structural surface of the product.

[0035] In order to be able to detect the internal gap in the middle position of the product, on the one hand, the height of the vertical end 6 does not exceed the height of the inner surface of the product to be detected. After installation, the gap difference between the top of the vertical end 6 and the inner surface of the product to be detected is required to be equal to the detection range of the go / no-go gauge 7; on the other hand, a limiting column 8 is set at the position corresponding to the through hole of the product on the installation table 3. The height of the limiting column 8 is greater than the height setting of the through hole of the through-hole product, which can prevent the product from moving and falling after installation. In addition, the outer diameter of the limiting column 8 is not greater than the inner diameter of the through hole of the product to be detected, which facilitates the alignment installation while avoiding damage to the through hole of the product.

[0036] It should be specifically explained that after the product is installed, it is necessary to further fix the product to ensure that the product will not change and affect the measurement result when the go / no-go gauge 7 is measured. Therefore, two sets of clamp units are installed at one end of the side of the base 1 close to the support base 2. The clamp unit includes a clamp base 11, a clamp 4, and a reference block 10. The clamp base 11 is installed on one side of the base 1 close to the horizontal end of the support base 2. The connecting seat of the clamp 4 is installed on the clamp base 11. When clamped, the end portion is located directly above the product to be tested. The reference block 10 is vertically fixed to the base 11. The direct pressure is arranged on the part of the product to be inspected which is located on the mounting table 3, and the top is abutted against the abutting end of the clamp 4, wherein the bottom of the reference block 10 is provided with a groove which is clamped on the part of the limiting column 8 which protrudes out of the product to be inspected. Since the outer diameter of the reference block 10 is larger than the outer diameter of the limiting column 8, when the clamp unit is pressed on both sides of the product to be inspected at the detection gap position through the clamp 4, the surface of the product will not be damaged, and a buffering and protective effect will be played. In addition, the go / no-go gauge 7 is arranged on one side of the base 1 close to the support seat 2 through a mounting frame for easy taking.

[0037] As mentioned above, the through holes to be inspected at both ends of the product are used as the positioning positions of the support base 2, and the through holes of the product to be inspected are manually operated using the positioning pins 5 installed on the base 1.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
