Terms defined in commonly used dictionaries are additionally interpreted as having meanings consistent with relevant technical literature and the current message. Unless otherwise defined, they should not be overly interpreted as ideal or highly formalized meanings.

[0039] In related technologies, when inspecting a part, such as a sensor, the sensor is typically placed on a support base, with its center positioned by positioning posts on the support base. With this positioning method, when the inspection tool touches the peripheral portion of the part, the peripheral portion of the part can still move, affecting the inspection of the part.

[0040] In view of this, an embodiment of the present disclosure provides a positioning device for a detection device. After the positioning device of the present disclosure positions the part to be tested, the peripheral portion of the part to be tested having the part to be tested is difficult to move, which is conducive to the smooth detection of the part to be tested.

[0041] Figure 1 It is a structural diagram of a positioning device for detecting equipment according to an embodiment of the present disclosure. Figure 2 yes Figure 1 A top view of the central structure. Figure 1 and Figure 2 The positioning device for detecting equipment according to the embodiment of the present disclosure includes a device body 11 and at least one pressing assembly 12 .

[0042] The device body 11 is provided with a main positioning hole 102 for positioning the mounting portion of the part to be tested. Therefore, when the mounting portion of the part to be tested is installed in the main positioning hole 102, the mounting portion of the part to be tested can be placed within the main positioning hole 102, and the peripheral portion located outside the mounting portion is located outside the main positioning hole 102.

[0043] For example, Figure 3 and Figure 4 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 3and Figure 4 In the case of the sensor shown, the mounting portion 91 may be one end portion of the sensor, the convex portion at the middle position of the sensor is the peripheral portion 92, and the peripheral portion 92 is provided with a portion to be measured 9201, i.e., a hole to be measured. The detection tool may be a detection shaft for inserting into the hole to be measured with a qualified aperture, so that when the detection shaft can be inserted into the hole to be measured of the part to be measured 900, it can be detected that the aperture of the hole to be measured is qualified. When the detection shaft cannot be inserted into the hole to be measured of the part to be measured 900, it means that the aperture of the hole to be measured is too small, and the aperture of the hole to be measured is unqualified. In the related art, if only the central part of the sensor is supported and positioned by the positioning column, then when the detection shaft is inserted into the hole to be measured for detection, the peripheral portion 92 of the sensor is easy to move, affecting the insertion detection process of the detection shaft.

[0044] Optionally, see Figure 1 The main positioning hole 102 is located on the standing surface of the device body 11. Therefore, when the part to be tested 900 is mounted in the main positioning hole 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 convenient for the user to perform relevant inspection operations from the side (e.g., the front side) of the standing surface while standing.

[0045] See Figure 1 and Figure 2 , each of the clamping components 12 includes a clamping member 121 and an elastic member 122. The force transmission member 123 is movably arranged on the device body 11. The clamping member 121 is connected to the force transmission member 123 in a linkage movement with the clamping member 121, and is provided with an exposure port 12101, so that when it moves to the clamping position, the exposure port 12101 exposes the part to be tested 9201 and compresses the peripheral part 92, that is, the part to be tested 9201 is located inside the exposure port 12101 and is exposed by the exposure port 12101, and when it moves to the release position, the peripheral part 92 is released. The elastic member 122 is connected to the clamping member 121 and the device body 11 for transmitting force, and is used to provide the clamping member 121 with an elastic force to maintain it in the clamping position through the force transmission member 123.

[0046] Thus, when the pressing member 121 is in the pressing position, under the elastic force provided by the elastic member 122, the pressing member 121 presses the outer portion 92 of the part to be tested 900 against the device body 11, and places the part to be tested 9201 within the exposure opening 12101 and is exposed through the exposure opening 12101. Since the area around the part to be tested 9201 is pressed by the pressing member 121, when the testing tool is testing the part to be tested 9201, the area around the part to be tested 9201 is difficult to move, and the stability is high, which is conducive to improving the stability of the part to be tested 9201 during testing. After the testing of the part to be tested 900 is completed, the pressing member 121 can move to the release position to release the outer portion 92, thereby facilitating the unloading of the part to be tested 900.

[0047] In the above process, after the positioning device positions the part to be tested 900, the outer portion 92 of the part to be tested 900 having the part to be tested 9201 is pressed by the clamping member 121, and the outer portion 92 is difficult to move during the detection process, which is conducive to the smooth detection of the part to be tested 9201.

[0048] Optionally, each of the compression assemblies 12 further includes a force transmission member 123. The force transmission member 123 is movable along a predetermined direction and extends out of the device body 11, and the extending portion is interlockingly connected to the compression member 121. Both ends of the elastic member 122 are disposed against the side surfaces of the force transmission member 123 and the device body 11 facing away from the compression member 121.

[0049] Thus, the force transmission member 123 can move in conjunction with the movement of the pressing member 121, for example, move synchronously with the pressing member 121 as the pressing member 121 moves, and the elastic force of the elastic member 122 acting on the force transmission member 123 can act on the pressing member 121, thereby driving the pressing member 121 to reset and maintain it in the pressing position.

[0050] Optionally, the force transmission member 123 is movably and rotatably provided on the device body 11 , and in the released position, the pressing member 121 is attached to the device body 11 and is located outside the installation coverage area of ​​the part to be tested 900 on the device body 11 .

[0051] Therefore, when the part to be tested 900 is not installed on the device main body 11, the pressing member 121 is located in the released position, the pressing member 121 is attached to the device main body 11, and is located outside the installation coverage area of ​​the part to be tested 900 on the device main body 11. Therefore, the pressing member 121 avoids the installation coverage area of ​​the part to be tested 900 on the device main body 11, making it convenient for the part to be tested 900 to be installed on the device main body 11. After the part to be tested 900 is installed on the device body 11, the pressing member 121 is moved away from the device body 11, and the pressing member 121 is rotated so that the pressing member 121 extends into the installation covering area, and the exposed opening 12101 on the pressing member 121 is aligned with the part to be tested 9201. At this time, the pressing member 121 is released, and under the elastic force of the elastic member 122, the pressing member 121 presses the part to be tested 900 so that the exposed opening 12101 exposes the part to be tested 9201.

[0052] When the inspection of the part to be tested 900 is completed, the pressing member 121 is moved away from the part to be tested 900, and the pressing member 121 is rotated again in the direction opposite to the previous rotation direction, so that the pressing member 121 avoids the installation coverage area of ​​the part to be tested 900 on the equipment main body 11. At this time, the pressing member 121 is released, and under the elastic force of the elastic member 122, the pressing member 121 is again tightly attached to the device main body 11, thereby facilitating the loading and inspection of the next part to be tested 900.

[0053] Optionally, see Figure 1 There are multiple pressing assemblies 12, and the multiple pressing assemblies 12 are arranged at intervals along the circumference of the main positioning hole 102 to press the multiple test parts 9201 of the peripheral part 92 in a one-to-one correspondence.

[0054] Optionally, see Figure 1 and Figure 3 , the mounting portion 91 is rotatably engaged with the main positioning hole 102. Figure 3 and Figure 4 The part to be tested 900 is provided with an eccentric positioning hole 903 which is eccentrically arranged relative to the center of the mounting portion 91 .

[0055] See Figure 1 and Figure 4 The positioning device for detecting equipment further includes an eccentric positioning member 13. The eccentric positioning member 13 is movably provided on the device body 11 in a direction away from or approaching the eccentric positioning hole 903, and has an eccentric positioning portion 131 that cooperates with the eccentric positioning hole 903 when moving closer.

[0056] Therefore, when the part to be measured 900 is installed to the device body 11, the mounting portion 91 of the part to be measured 900 can be rotatably placed in the main positioning hole 102, and then the part to be measured 900 is rotated until the part to be measured 900 is rotated to a predetermined position, and the eccentric positioning member 13 is driven to move, so that the eccentric positioning portion 131 of the eccentric positioning member 13 is configured in the eccentric positioning hole 903. Since the center of the eccentric positioning portion 131 is eccentric to the center of the main positioning hole 102, that is, there is a deviation between the axis of the eccentric positioning member 13 and the axis of the main positioning hole 102, the part to be measured 900 cannot rotate after being positioned by the eccentric positioning member 13, which can position the part to be measured 900 and limit the rotation of the part to be measured 900.

[0057] Optionally, the eccentric positioning member 13 is disposed in the device body 11 so as to be axially movable toward and away from the eccentric positioning hole 903. Thus, the eccentric positioning member 13 can only be successfully inserted into the eccentric positioning hole 903 when the part to be tested 900 is rotated so that the eccentric positioning hole 903 of the part to be tested 900 is rotated to a circumferential position aligned with the eccentric positioning portion 131. Conversely, if the eccentric positioning hole 903 of the part to be tested 900 has not been rotated to a circumferential position aligned with the eccentric positioning portion 131, the eccentric positioning member 13 cannot be successfully inserted into the eccentric positioning hole 903 by axial movement. Therefore, during the positioning process of the part to be tested 900, whether the eccentric positioning portion 131 can be successfully inserted into the eccentric positioning hole 903 can be determined, thereby ensuring that the eccentric positioning hole 903 is positioned at the predetermined circumferential position after positioning.

[0058] See Figure 2 The device body 11 is provided with a first guide portion 103, such as a first sliding hole, which extends linearly and slides with the eccentric positioning member 13. This helps ensure that the eccentric positioning member 13 moves stably during movement and is unlikely to deviate.

[0059] Optionally, see Figure 1 and Figure 3, the mounting portion 91 is provided with a limiting positioning hole 9101. The positioning device for the detection equipment also includes a limiting positioning member 14. The limiting positioning member 14 is movably provided on the device body 11 in the direction of being far from / near the limiting positioning hole 9101, and is arranged on opposite sides of the main positioning hole 102 with the eccentric positioning member 13, and has a limiting positioning portion 141 that cooperates with the limiting positioning hole 9101 when moving closer. Therefore, after the eccentric positioning portion 131 positions the part to be measured 900, the limiting positioning member 14 is driven to move close to the limiting positioning hole 9101, so that the limiting positioning portion 141 is cooperated with the limiting positioning hole 9101, thereby limiting and positioning the part to be measured 900 from the other side of the part to be measured 900, and having a good positioning effect on the part to be measured 900.

[0060] Optionally, the limiting positioning member 14 is movably provided on the device body 11 in a direction away from or close to the limiting positioning hole 9101. Thus, after the eccentric positioning portion 131 positions the part to be measured 900, the limiting positioning member 14 is driven to move closer to the limiting positioning hole 9101, and the limiting positioning portion 141 can be inserted into the limiting positioning hole 9101, thereby achieving mutual cooperation with the limiting positioning hole 9101.

[0061] Optionally, see Figure 2 The device body 11 is provided with a second guide portion 104, i.e., a second slide hole, which extends linearly and slides with the position limiting member 14. This helps ensure that the position limiting member 14 moves stably during movement and is unlikely to deviate.

[0062] The present disclosure also provides a testing device, comprising the aforementioned positioning device and a testing component. The positioning device is used to position a part 900 to be tested. The testing component is used to detect a testing portion 9201 of the positioned part 900 to be tested. For example, when the testing portion 9201 is a hole to be tested, the testing component may be the aforementioned testing shaft. The ability of the testing shaft to be successfully inserted into the hole to be tested is then used to determine whether the hole diameter is acceptable.

[0063] 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.
