A movable plate 200 is movably mounted on the second support block 120, and the second movable plate 300 is movably mounted on the third support block 130. During inspection, the product 400 is attached to the first support block 110, the second support block 120 and the third support block 130, and the positioning pin 114 passes through the positioning hole 410 to position and fix the product 400. The first movable plate 200 moves under the action of external force so that the first detection column 210 passes through the first detection hole 122 and the first processing hole 420. The second movable plate 300 moves under the action of external force so that the second detection column 310 passes through the second detection hole 132 and the second processing hole 430.
[0025] In this application, the first support block 110, the second support block 120 and the third support block 130 are used to place the product 400, and the positions and structures of the three support blocks are designed according to the shape of the product 400, that is, the three support blocks are combined into a contoured structure of the product 400, and the positioning pin 114 is installed on the first support block 110 according to the position of the positioning hole 410 on the product 400. The diameter of the first detection column 210 is processed according to the aperture of the first processing hole 420, and the diameter of the second detection column 310 is processed according to the aperture of the second processing hole 430 to ensure that the first detection column 210 can just pass through the first processing hole 420 and the second detection column 310 can just pass through the second processing hole 430. During inspection, the product 400 is placed on the first support block 110, the second support block 120 and the third support block 130, and the positioning pin 114 is inserted into the positioning hole 140 to quickly locate the position of the product 400, and the product 400 is pressed as much as possible, and then the product 400 is observed to see whether it fits with the first support block 110, the second support block 120 and the third support block 130.

If the first inspection column 210 can smoothly pass through the first processing hole 420 and the second inspection column 310 can smoothly pass through the second processing hole 430, it means that the position and aperture of the first processing hole 420 and the second processing hole 430 on the product 400 meet the standard.

The second support block 120 and the third support block 130 are respectively disposed on either side of the first support block 110. The second support block 120 and the third support block 130 are both close to the first support block 110 so that the product 400 can be placed on the first support block 110, the second support block 120, and the third support block 130.
[0027] like Figure 1As shown, the first support block 110 is provided with a first detection surface 111, a second detection surface 112, and a third detection surface 113. The first detection surface 111 is connected to the second detection surface 112 and the third detection surface 113 on both sides, and the positioning pin 114 is fixed to the first detection surface 111. The first detection surface 111 is arranged obliquely with respect to the upper surface 101, and the second detection surface 112 and the third detection surface 113 are both arranged perpendicular to the upper surface 101.
[0028] The second support block 120 is provided with a fourth detection surface 121, on which the first detection hole 122 is provided. The third support block 130 is provided with a fifth detection surface 131, on which the second detection hole 132 is provided. The fourth detection surface 121 and the fifth detection surface 131 are both arranged perpendicular to the upper surface 101. Optionally, the first detection surface 111, the second detection surface 112, the third detection surface 113, the fourth detection surface 121, and the fifth detection surface 131 are smooth planes, inclined surfaces, or curved surfaces. The first detection surface 111, the second detection surface 112, the third detection surface 113, the fourth detection surface 121, and the fifth detection surface 131 cooperate to form a contour of the product 30, ensuring that when the product 400 is qualified, the inner surface of the product 400 can fit on each detection surface.
[0029] The first detection column 210 and the second detection column 310 are both parallel to the upper surface 101. The first movable plate 200 and the second movable plate 300 can move in a horizontal direction.
[0030] The first end of the first detection post 210 is fixedly mounted on the first movable plate 200, and the second end of the first detection post 210 is inserted into the first detection hole 122. The first end of the second detection post 310 is fixedly mounted on the second movable plate 300, and the second end of the second detection post is inserted into the second detection hole 132. The first machined hole 420 corresponds to the first detection hole 122, and the second machined hole 430 corresponds to the second detection hole 132. The first detection post 210 and the second detection post 310 are used to detect the first machined hole 420 and the second machined hole 430, respectively.
[0031] The first movable panel 200 is connected to the second support block 120 via a first elastic component 220. The first end of the first elastic component 220 is fixedly connected to the first movable panel 200, and the second end of the first elastic component 220 is fixedly connected to the second support block 120. The second movable panel 300 is connected to the third support block 130 via a second elastic component 320. The first end of the second elastic component 320 is fixedly connected to the second movable panel 300, and the second end of the second elastic component 320 is fixedly connected to the third support block 130. The first movable panel 200 and the second movable panel 300 are mounted on the second support block 120 and the third support block 130 for horizontal movement. When an operator pushes the first movable panel 200 and the second movable panel 300 outward, the first movable panel 200 and the second movable panel 300 move toward the support blocks, compressing the first elastic component 220 and the second elastic component 320. When the operator releases the movable panels, the first movable panel 200 returns to its original position under the action of the first elastic component 220, and the second movable panel 300 returns to its original position under the action of the second elastic component 320. Optionally, a group of first elastic components 220 and two first detection columns 210 are provided on the first movable plate 200 , and a group of second elastic components 320 and two second detection columns 310 are provided on the second movable plate 300 .
[0032] The first elastic component 220 and the second elastic component 320 each include a pin, a spring, and a plug. The two ends of the spring are fixedly connected to the pin and the plug, respectively. The first end of the spring is fixedly mounted to the first movable plate 200 or the second movable plate 300 via the plug, and the second end of the spring is fixedly mounted to the second support block 120 or the third support block 130 via the pin. The first end of the spring is fixed to the plug, which is fixedly mounted to the first movable plate 200 or the second movable plate 300, and the second end of the spring is fixed to the pin, which is fixedly mounted to the second support block 120 or the third support block 130.
[0033] The operating method of the hole position detection fixture in this application includes the following steps:
[0034] Step 1: Place the product 400 on the first support block 110 , the second support block 120 , and the third support block 130 , and insert the positioning pin 114 through the positioning hole 410 on the product 400 ;
[0035] Step 2: Press the product 400 toward the support block so that the inner surface of the product 400 fits as closely as possible to the test surfaces. If the inner surface of the product 400 does not fit the test surfaces, the shape of the product 400 is determined to be unqualified.
[0036] Step 3: If the shape of the product is qualified, the operator pushes the first movable plate 200 and the second movable plate 300 outward, and the first detection column 210 and the second detection column 310 move synchronously. If the first detection column 210 can smoothly pass through the first processing hole 420 on the product 400, and the second detection column 310 can smoothly pass through the second processing hole 430 on the product 400, the product 400 is judged to be a qualified product. Otherwise, it is judged that the size or position of the processing hole does not meet the requirements.
[0037] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
