Embodiments of the present disclosure can be executed independently of each other, or can be executed together in a mutually dependent relationship.

[0038] With reference to Figs. 1 to 3 , the present application discloses a rapid detection method for inter-hole position degree,

[0039] In example one, there are only four holes 11 of the same specification on the workpiece 5, and only the position degree between the four holes 11 needs to be detected. Therefore, four detection needles (not shown in the figure) and a detection plate 1 are included. The detection needles and the detection plate 1 are processed according to the following steps and the workpiece 5 is detected:

[0040] First, the hole diameter D1±S of the hole 11 to be detected and the position size between the holes 11 to be detected and the position degree tolerance A between the holes 11 to be detected are obtained by processing the drawing. For example, the hole diameter of the hole 11 to be detected is marked as 7mm±0.2 on the processing drawing, the position degree tolerance between the holes 11 to be detected is 0.3mm, D1=7mm, S=0.2mm, and A=0.3mm,

[0041] Second, the diameter of the detection needle and the hole diameter of the detection hole 21 are calculated. The diameter of the detection needle is D1-S, and the hole diameter of the detection hole 21 is D1+S+A. Therefore, the diameter of the detection needle is 7-0.2=6.8mm, and the hole diameter of the detection hole 21 is 7+0.2+0.3=7.5mm,

[0042] Three, according to the diameter of the detection needle one, the detection needle one is processed, the reference detection surface 2 is processed on the detection plate 1, and the detection hole one 21 is processed on the reference detection surface 2 according to the position size between the to-be-detected hole one 11 and the hole diameter size of the detection hole one 21, and the reference detection surface 2 is precisely milled, the precision is high, and the detection requirements are met. The flat side of the workpiece 5 and the reference detection surface 2 is also a reference surface. Four, the workpiece 5 is placed on the detection plate 1, and the to-be-detected hole one 11 on the workpiece 5 is overlapped with the corresponding detection hole one 21. All to-be-detected holes one 11 and the corresponding detection hole one 21 are inserted with detection needles one. If the detection needle one can be smoothly inserted into each to-be-detected hole one 11 and the corresponding detection hole one 21, it means that the workpiece 5 is qualified; if the detection needle one cannot be inserted into the corresponding detection hole one 21 through a to-be-detected hole one 11, it means that the workpiece 5 is unqualified.

[0043] In the embodiment, the workpiece 5 also has four to-be-detected holes two 12 of another specification, and the position tolerance between the four to-be-detected holes two 12 also needs to be detected. Therefore, four detection needles two (not shown in the figure) are also included. The detection needles two and the detection plate 1 are processed according to the following steps, and the detection of the workpiece 5 is performed.

[0044] In step one, the hole diameter D2 of the to-be-detected hole two 12 also needs to be obtained through the processing drawing

[0045] ±E, the position size between the to-be-detected hole two 12 and the position tolerance B between the to-be-detected hole two 12, the hole diameter value of the to-be-detected hole two 12 is 5mm±0.2, the position tolerance between the to-be-detected hole two 12 is 0.2mm, D2=5mm, E=0.2mm, B=0.2mm,

[0046] In step two, the diameter of the detection needle two and the hole diameter of the detection hole two 22 are calculated, so that the diameter of the detection needle two is D2-E, and the hole diameter of the detection hole two 22 is D2+E+B. The diameter of the detection needle two is 5-0.2=4.8mm; the hole diameter of the detection hole two 22 is 5+0.2+0.2=5.4mm,

[0047] In step three, the detection needle two is processed according to the diameter of the detection needle two, and the detection hole two 22 is processed on the reference detection surface 2 according to the position size between the to-be-detected hole two 12 and the hole diameter size of the detection hole two 22,

[0048] In step four, the to-be-detected hole two 12 on the workpiece 5 is overlapped with the corresponding detection hole two 22, and all to-be-detected holes two 12 and the corresponding detection hole two 22 are inserted with detection needles two. If the detection needle two can be smoothly inserted into each to-be-detected hole two 12 and the corresponding detection hole two 22, it means that the workpiece 5 is qualified; if the detection needle two cannot be inserted into the corresponding detection hole one 21 through a to-be-detected hole two 12, it means that the workpiece 5 is unqualified.

[0049] In the third embodiment, the position tolerance A between the first detection hole 11, the second detection hole 12 and the first detection hole 11 and the second detection hole 12 needs to be detected simultaneously,

[0050] Thus in step one, A=0.3mm is obtained by processing the drawing,

[0051] Thus in step two, the hole diameter of the third detection hole 23 also needs to be calculated, and the hole diameter of the third detection hole 23 is D2+S+A, that is, 5+0.2+0.3=5.5mm

[0052] Thus in step three, the third detection hole 23 is processed on the reference detection surface 2 according to the position size of the second detection hole 12 and the hole diameter size of the third detection hole 23,

[0053] Thus in step four, the first detection hole 11 on the workpiece 5 is overlapped with the corresponding first detection hole 21, and the second detection hole 12 on the workpiece 5 is overlapped with the corresponding third detection hole 23, all the first detection holes 11 and the corresponding first detection holes 21 are inserted with the detection needle one, and all the second detection holes 12 and the corresponding third detection holes 23 are inserted with the detection needle two, if the detection needle one can be smoothly inserted into each first detection hole 11 and the corresponding first detection hole 21, and the detection needle two can be smoothly inserted into each second detection hole 12 and the corresponding third detection hole 23, it means that the workpiece 5 is qualified; if the detection needle one cannot be inserted into the corresponding first detection hole 21 through a certain first detection hole 11, or the detection needle two cannot be inserted into the corresponding third detection hole 23 through a certain second detection hole 12, it means that the workpiece 5 is unqualified.

[0054] In the above, the hole diameter of the detection hole is precisely processed according to the required size on the processing drawing of the workpiece 5, the diameter of the detection needle is also accurate, the tolerance of the detection needle and the detection hole can be ignored, and the relative position tolerance of the detection hole is ensured by the accuracy of the processing equipment. The position tolerance accuracy of the processing equipment for processing the detection hole is much greater than the accuracy requirement of the position tolerance between the detection holes, so the position tolerance between the detection holes can be ignored.

[0055] As shown in the figure, the reference detection surface 2 is provided with a protrusion one 3, the second detection hole 22 is arranged on the protrusion one 3, the reference detection surface 2 is provided with a protrusion two 4, and the third detection hole 23 is arranged on the protrusion two 4. Because there is a gap below the area where the second detection hole 12 of the workpiece 5 is located, the distance between the second detection hole 12 and the second detection hole 22 or the third detection hole 23 can be avoided by the protrusion, so that the length of the detection needle two is increased.

[0056] In order to facilitate the alignment position, the reference detection surface 2 is provided with the outline 5 of the product, the detection holes are located in the outline 5, the shape of the outline 5 is the shape of the workpiece 5, and thus the workpiece 5 is placed in the outline 5, so that the to-be-detected hole is aligned with the corresponding detection hole, and the workpiece 5 is quickly aligned.

[0057] The above describes in detail the quick detection method of the hole position degree provided by the embodiment of the present application, and the principle and implementation mode of the present application are described by using specific examples; the above embodiment is only used for helping to understand the method of the present application and the core idea; meanwhile, for the general technical personnel in the field, the specific implementation mode and the application range will be changed according to the idea of the present application, and the above description should not be understood as the limitation of the present application.
