[0038] In related technologies, the inspection of holes to be measured on parts, such as the position and diameter of holes on sensors, is often performed using a three-dimensional coordinate measuring machine (CMM). This machine uses a probe to repeatedly move and measure multiple coordinate values at multiple points on the hole to be measured. These coordinate values are then processed by a processor to determine whether the position and diameter of the hole to be measured are acceptable. These CMMs are complex in structure, expensive, and difficult to operate, which impacts the efficiency of hole inspection.
[0039] In view of this, the present disclosure provides a detection device, which is mainly used to detect the circumferential position of the hole to be tested of the part to be tested and whether the aperture is qualified. The detection device has a simple structure, low cost, and is easy to operate, which is conducive to improving the detection efficiency of the hole to be tested of the part.
[0040] Figure 1 Schematic diagram of the structure of the detection device of the embodiment of the present disclosure. Figure 1 The detection device of the embodiment of the present disclosure includes a device body 11 and an eccentric positioning member 12.
[0041] The device body 11 is provided with a rotational engagement portion 102 for rotationally engaging with the mounting portion of the part to be tested, and a detection hole 103 located on the periphery of the rotational engagement portion 102. Thus, when the mounting portion of the part to be tested is attached to the rotational engagement portion 102, the part to be tested can rotate about the center of the rotational engagement portion 102. Furthermore, the part to be tested is provided with an eccentric positioning hole, eccentrically positioned relative to the center of the mounting portion, and a detection hole located on the periphery of the eccentric positioning hole.
[0042] For example, Figure 2 and Figure 3 The structure diagram of the part to be tested 900 in different viewing angles of the embodiment of the present disclosure is shown in FIG. Figure 2 and Figure 3 In the illustrated sensor, the mounting portion 91 may be one end of the sensor, and the eccentric positioning hole 903 may be a countersunk hole located at the other end of the sensor. The center of the eccentric positioning hole 903 is offset from the center of the sensor end, and the two are eccentrically arranged. The middle portion of the sensor protrudes radially outward and is provided with a test hole 9201 located outside the eccentric positioning hole 903.
[0043] Optionally, see Figure 1 The rotational fitting portion 102 includes a rotational positioning hole for sleeved on the outside of the mounting portion 91. Thus, when the mounting portion 91 of the part to be tested 900 is mounted to the rotational positioning hole, the part to be tested 900 can rotate around the center of the rotational positioning hole.
[0044] Optionally, the rotational engagement portion 102 is located on the standing surface of the device body 11. Thus, when the part to be tested 900 is mounted on the rotational engagement portion 102, the part to be tested 900 is directly mounted on the standing surface, making it convenient to arrange other components from the side (e.g., the front or rear side) of the standing surface, and making it convenient for a user to perform relevant inspection operations from the side (e.g., the front side) of the standing surface while standing.
[0045] The axis of the eccentric positioning member 12 is eccentrically arranged relative to the axis of the rotating matching portion 102, and is arranged on the device body 11 so as to be movable axially toward / away from the eccentric positioning hole 903, and has an eccentric positioning portion 121 that cooperates with the eccentric positioning hole 903 when moving closer.
[0046] Therefore, after the mounting portion 91 of the part to be tested 900 is mounted on the rotational fitting portion 102 , the part to be tested 900 may be rotated to align the eccentric positioning hole 903 of the part to be tested 900 with the eccentric positioning portion 121 .
[0047] At this time, the eccentric positioning member 12 is moved closer to the rotational engagement portion 102. If the eccentric positioning hole 903 and the eccentric positioning portion 121 are not aligned, the eccentric positioning portion 121 cannot be smoothly inserted into the eccentric positioning hole 903. In this case, the part to be tested 900 can be rotated accordingly until the eccentric positioning portion 121 can be smoothly inserted into the eccentric positioning hole 903. Because the center of the eccentric positioning portion 121 is eccentric relative to the center of the rotational engagement portion 102, the part to be tested 900 is stopped from rotating and can remain stable, and cannot continue to rotate about the axis of the rotational engagement portion 102.
[0048] Furthermore, the circumferential position of the detection hole 103 in the circumferential direction of the eccentric positioning portion 121 is consistent with the circumferential position of the hole to be tested 9201 with qualified positioning accuracy in the circumferential direction of the eccentric positioning hole 903. In other words, after the eccentric positioning hole 903 of a qualified part is positioned by the eccentric positioning portion 121, the circumferential position of the hole to be tested 9201 with qualified positioning accuracy on the qualified part is consistent with the circumferential position of the detection hole 103, and the hole to be tested 9201 and the detection hole 103 of the qualified part will overlap and be in electrical communication with each other. Therefore, if the circumferential position of the hole to be tested 9201 of the part to be tested 900 is qualified, the circumferential position of the hole to be tested 9201 of the part to be tested 900 positioned by the eccentric positioning portion 121 will also overlap with the circumferential position of the detection hole 103, and the hole to be tested 9201 and the detection hole 103 will be in electrical communication with each other. On the contrary, if the circumferential position of the hole to be measured 9201 of the part to be measured 900 is unqualified, the circumferential position of the hole to be measured 9201 of the part to be measured 900 positioned by the eccentric positioning portion 121 will be staggered with the circumferential position of the detection hole 103, and the hole to be measured 9201 and the detection hole 103 will not be conductive.
[0049] Therefore, whether the hole to be tested 9201 of the part to be tested 900 positioned by the eccentric positioning member 12 is in continuity with the detection hole 103 can reflect whether the circumferential position accuracy of the hole to be tested 9201 is qualified. The above-mentioned detection device has a simple structure and low cost. During the detection process, after the eccentric positioning member 121 is operated to engage with the eccentric positioning hole 903, it is only necessary to observe whether the hole to be tested 9201 is in continuity with the detection hole 103 to determine whether the circumferential position accuracy of the hole to be tested 9201 is qualified. This is convenient to operate and helps improve detection efficiency.
[0050] Figure 4 yes Figure 1 Schematic diagram of the top view of the central part of the structure. Figure 1 and Figure 4 The device body 11 is provided with a first guide slide portion 104 extending in a straight line and slidingly cooperating with the eccentric positioning member 12. Thus, when the eccentric positioning member 12 moves along the extension direction of the first guide slide portion 104, the eccentric positioning member 12 is unlikely to deviate.
[0051] Optionally, the first guide portion 104 is configured as a first sliding hole, the eccentric positioning member 12 is slidably engaged in the first sliding hole, and a first anti-slip portion 122 is provided at one end of the eccentric positioning member 12 facing away from the rotational engagement portion 102 to prevent the eccentric positioning member 12 from slipping out of the first sliding hole. Thus, when the eccentric positioning member 12 moves closer to the rotational engagement portion 102, the eccentric positioning member 12 is unlikely to slip out of the first sliding hole.
[0052] Optionally, see Figure 1 There are multiple detection holes 103, and the circumferential positional accuracy of the multiple detection holes 103 along the circumference of the eccentric positioning portion 121 corresponds one-to-one with the circumferential positional accuracy of the multiple test holes 9201 that have passed the test. Therefore, by observing whether the multiple test holes 9201 are electrically connected to the multiple detection holes 103 in a one-to-one correspondence, it can be determined whether the circumferential positional accuracy of the multiple test holes 9201 meets the requirements.
[0053] Figure 5 Schematic diagram of the structure of the detection axis of the embodiment of the present disclosure. Figure 3 and Figure 5 , the detection device also includes a detection shaft 13. The detection shaft 13 includes a detection head 131, and the outer diameter of the detection head 131 is configured to allow it to be plugged into and matched with the hole to be measured 9201 with a qualified aperture. In other words, when the hole to be measured 9201 with a qualified aperture on a qualified part is inserted by the detection head 131, the detection head 131 can be smoothly plugged into the hole to be measured 9201 with a qualified aperture on the qualified part. Therefore, when the aperture of the hole to be measured 9201 of the part to be measured 900 is detected, if the detection head 131 can be inserted into the hole to be measured 9201 of the part to be measured 900, it means that the aperture of the hole to be measured 9201 of the part to be measured 900 is qualified. On the contrary, if the detection head 131 cannot be inserted into the hole to be measured 9201 of the part to be measured 900, it means that the inner diameter of the hole to be measured 9201 of the part to be measured 900 is too small and the processing is unqualified.
[0054] Optionally, the outer diameter of the detection head 131 is further configured to allow for plug-in engagement with the detection hole 103. Thus, when testing the circumferential position of the hole 9201 to be tested, the detection head 131 can be directly inserted through the hole 9201 to be tested of the part 900 to be tested and into the detection hole 103. If the detection head 131 is successfully inserted, it indicates that the detection hole 103 and the hole 9201 to be tested of the part 900 to be tested are electrically connected, and the circumferential position of the hole 9201 to be tested is qualified. Conversely, if the detection head 131 cannot be successfully inserted, it indicates that the detection hole 103 and the hole 9201 to be tested of the part 900 to be tested are not electrically connected, and the circumferential position of the hole 9201 to be tested is unqualified. Therefore, the user can directly insert the detection shaft 13 while standing. According to the insertion status of the detection shaft 13, that is, whether it is inserted into the hole to be measured 9201 and whether it passes through the hole to be measured 9201 and is inserted into the detection hole 103, it can be judged whether the aperture of the hole to be measured 9201 and the circumferential position of the hole to be measured 9201 are qualified. One insertion action can detect multiple parameters of the hole to be measured 9201, and the detection efficiency is high.
[0055] Optionally, the detection shaft 13 further includes a gripping portion 132. The gripping portion 132 is detachably connected to the detection head 131. Thus, a user can insert or remove the detection shaft 13 by gripping the gripping portion 132 and applying pressure or tension thereto. Furthermore, the detection head 131 can be easily replaced and maintained.
[0056] Optionally, the cross-section of the grip portion 132 is a regular polygon. Thus, when a user grips the grip portion 132, the friction between the user's hand and the grip portion 132 is relatively large, making it difficult for the user's hand to separate from the grip portion 132 while gripping and driving the grip portion 132 to move.
[0057] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, any equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be encompassed by the scope of protection of this disclosure.
