[0002] Nowadays, many precision products / parts no longer use traditional straight up and down holes. Instead, inclined holes may be opened on some planes. When measuring the position and size of the inclined holes, projection measurement cannot be used because they are not straight holes. However, if they are not measured, when the size and position of the inclined holes do not meet the standards, assembly problems will occur.

[0003] The Chinese utility model patent with authorization announcement number CN219342140U discloses an inclined hole detection auxiliary device, a fixing component and an angle adjustment component; the fixing component is used to fix the product to be detected, and the angle adjustment component has an inclined surface at a first angle; the fixing component is arranged on the inclined surface of the angle adjustment component so that the inclined hole of the product to be detected is parallel to the vertical direction. Among them, the fixed parts include a base, a pressure block, a stop block, a guide block, a guide rod, an elastic element and a limit piece; the pressure block is movably arranged on the base, the stop block and the guide block are fixedly arranged on the base, the pressure block and the stop block can be used to place the product to be detected, one end of the guide rod is connected with the pressure block, the guide rod passes through the guide block and is connected with the pressure block, the elastic element is sleeved on the guide rod between the guide block and the pressure block, the pressure block is used to contact with the product to be detected, the product to be detected is fixed by the pressure block and the stop block to ensure that it does not move during the detection process, thereby improving the accuracy of inclined hole detection; through the utility model, it can be ensured that the inclined hole opened on the product to be detected is always in the vertical direction during the two-dimensional projection detection process, so that it is a vertical hole relative to the two-dimensional projection detection device, thereby improving the accuracy of inclined hole detection.

[0004] However, the fixed parts used to position the product have a complex structure, many parts, and are not convenient to operate. Fig.10 The part 1 to be inspected with obliquely punched precision microholes shown in the figure is provided with a plurality of circular obliquely punched precision microholes 11, and the obliquely punched precision microholes 11 are all inclined from the inside to the outside. When the above-mentioned oblique hole detection auxiliary device is used for the obliquely punched precision microholes 11, it is necessary to continuously loosen the limiter so that the guide rod can slide relative to the guide block, so that the pressure block no longer presses the part 1 to be inspected, and then adjust the angle of the part 1 to be inspected so that the next obliquely punched precision microhole 11 is in a vertical state, and then lock the limiter so that the pressure block presses the part 1 to be inspected for later inspection. Since the number of parts 1 to be inspected is large, it is necessary to continuously adjust the parts of the fixed component, continuously loosen the pressure block, adjust the angle of the part 1 to be inspected, and then adjust the pressure block to press the part 1 to be inspected, which is extremely inconvenient to operate.

[0028] The utility model is further described below in conjunction with specific embodiments and drawings.

[0029] See Figure 1-9 As shown, an oblique punching precision micro-hole detection jig can be used to detect a porous product 1 to be detected, wherein the product 1 to be detected is provided with a plurality of oblique punching precision micro-holes 11 inclined from the inside to the outside, and all the oblique punching precision micro-holes 11 are distributed in a circle.

[0030] The utility model oblique punching precision micro-hole detection fixture includes a base 2 and a first limit block 3 and a second limit block 4 installed on the inclined surface 20 at the upper end of the base 2, wherein a limit space 200 for limiting the product 1 to be detected is formed between the first limit block 3 and the second limit block 4. Since the first limit block 3 and the second limit block 4 are installed on the inclined surface 20, the first limit block 3 and the second limit block 4 are also distributed in an inclined manner, so that the limit space 200 is also in an inclined state. When the product 1 to be detected is placed in the limit space 200, the product 1 to be detected is in an inclined state, and at least one oblique punching precision microhole 11 of the product 1 to be detected is in a vertical direction, so as to realize the detection of the oblique punching precision microhole 11.

[0031] In order to be able to more conveniently control other obliquely punched precision microholes 11 of the product 1 to be inspected that are not originally in the vertical direction to be able to move quickly to the vertical direction, the following design is also made: a rotatable turntable 5 is also provided on the base 2, and the turntable 5 is located below the first limit block 3 and the second limit block 4 and is placed at the bottom of the limit space 200; when the product 1 to be inspected is placed in the limit space 200 and is supported on the upper end surface of the turntable 5, the product 1 to be inspected can be driven to rotate by rotating the turntable 5, so that the other obliquely punched precision microhole 11 is in the vertical direction. That is to say, the utility model carries the product 1 to be inspected through the turntable 5, the first limit block 3 and the second limit block 4, and can limit the product 1 to be inspected. It has a simple structure, few parts, and is easy to operate. After the obliquely punched precision microholes 11 of the product 1 to be inspected that are in the vertical direction are inspected, when it is necessary to inspect other obliquely punched precision microholes 11 of the product 1 to be inspected that are not originally in the vertical direction, the turntable 5 can be directly driven to drive the product 1 to be inspected to rotate in the limiting space 200, so that the next obliquely punched precision microhole 11 of the product 1 to be inspected is in the vertical direction, so as to realize the inspection. The operation steps are very few, and only the turntable 5 needs to be rotated. It is extremely convenient to operate, and the time is short and the efficiency is high, so that all the obliquely punched precision microholes 11 of the product 1 to be inspected can be quickly inspected, which can greatly improve the inspection efficiency and make the utility model have strong market competitiveness.

[0032] The turntable 5 is provided with a through hole 51 penetrating the upper and lower end surfaces in the middle, the vertically obliquely punched precision micro-hole 11 is located above the through hole 51, and the extension line 111 of the obliquely punched precision micro-hole 11 can pass through the through hole 51. In addition, the base 2 is also provided with an inner hole 21 penetrating the upper and lower ends, and the inner hole 21 is located below the through hole 51.

Among them, the diameter of the movable groove 22 is slightly larger than the diameter of the turntable 5. While being able to limit the turntable 5, a certain space is required to allow the turntable 5 to rotate relative to the movable groove 22. Among them, the movable groove 22 is formed by adding the third limit block 6 and the fourth limit block 7, so that when a larger or smaller turntable is used later, the third limit block 6 and the fourth limit block 7 with the third curved surface 61 and the fourth curved surface 71 of different sizes can be replaced, so that the third limit block 6 and the fourth limit block 7 can adapt to the turntable of larger or smaller size to meet different usage requirements.

[0036] The opposing surfaces of the first limiting block 3 and the second limiting block 4 are also provided with a first limiting concave arc surface 31 and a second limiting concave arc surface 41, and the limiting space 200 is formed between the first limiting concave arc surface 31 and the second limiting concave arc surface 41. The outer side surface of the product 1 to be detected does not contact at least one of the first limiting concave arc surface 31 and the second limiting concave arc surface 41, so that the product 1 to be detected can rotate in the limiting space 200.

[0037] The upper ends of the opposite surfaces of the first limit block 3 and the second limit block 4 are respectively provided with a first inclined surface 32 and a second inclined surface 42, and the first inclined surface 32 and the second inclined surface 42 are respectively connected to the first limit concave arc surface 31 and the second limit concave arc surface 41, which can better highlight the first limit concave arc surface 31 and the second limit concave arc surface 41, and then can better reveal the product 1 to be inspected, so that the product 1 to be inspected can be better assembled and it is more convenient to use.

[0040] The contact area between the upper end of the turntable 5 and the product 1 to be detected is provided with a rough surface for friction. When the product 1 to be detected is placed in the limited space and on the rough surface of the upper end of the turntable 5, when the turntable 5 rotates, the product 1 to be detected can be driven to rotate synchronously more smoothly, and then the product 1 to be detected can be driven to rotate smoothly, so as to achieve better detection efficiency.

[0041] To sum up, the utility model carries the product 1 to be inspected through the turntable 5, the first limit block 3 and the second limit block 4, and can limit the product 1 to be inspected. It has a simple structure, few parts, and is easy to operate. After inspecting the obliquely punched precision microholes 11 of the product 1 to be inspected that are in the vertical direction, when it is necessary to inspect other obliquely punched precision microholes 11 of the product 1 to be inspected that are not originally in the vertical direction, the turntable 5 can be directly driven to drive the product 1 to be inspected to rotate in the limiting space 200, so that the next obliquely punched precision microhole 11 of the product 1 to be inspected is in the vertical direction, so as to realize the inspection. The operation steps are very few, and only the turntable 5 needs to be rotated. The operation is extremely convenient, short in time, and highly efficient, so that all the obliquely punched precision microholes 11 of the product 1 to be inspected can be quickly inspected, which can greatly improve the inspection efficiency and make the utility model have strong market competitiveness.
