[0031] In order to clearly illustrate the present disclosure, devices irrelevant to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0032] Throughout the specification, when it is said that a device is "connected" to another device, this includes not only the case of "direct connection", but also the case of "indirect connection" in which other elements are placed in between.

[0036] When using an industrial detector to inspect the inside of a part, since the detector wire harness is made of a soft material and the inside is a cable, the operator cannot accurately control the movement of the detection head of the detector to a specified height and rotate it by a specified angle, resulting in the inability to efficiently and accurately detect the internal condition of the part to be tested.

[0037] Based on the above problems, in the embodiments of the present disclosure, a positioning component is provided. By passing the wire harness of the detector through the lumen of the sleeve, and clamping the detection head of the detector in the fixed connection part at the end of the sleeve, the detection head of the detector can be driven to rotate when the positioning component rotates, and at the same time, when the sleeve moves up and down, the detection head of the detector can also be driven to move up and down.

[0038] Figure 1 Shown is a cross-sectional schematic diagram of the overall structure of the positioning component in the embodiments of the present disclosure. Figure 2 Shown is a cross-sectional schematic diagram of the overall structure of the cooperation between the positioning component and the detector in the embodiments of the present disclosure. In Figure 1 and Figure 2 In the example, the positioning component includes a sleeve 1O and a measuring member 20. The sleeve 1O includes a lumen 1O1 extending along an axis between two ends of the sleeve 1O, and an operation port 102 and a detection port 103 respectively provided at the proximal end and the distal end of the two ends and communicating with the lumen 1O1. Exemplarily, the operation port 102 is for the wire harness 41 of the detector 40 to penetrate, and the detection port 103 is for the wire harness 41 of the detector 40 to penetrate out. Exemplarily, the aperture of the lumen 1O1 is larger than the wire diameter of the wire harness 41 of the detector 40. Exemplarily, the sleeve 1O is implemented to be made of a rigid material to prevent the sleeve 1O from bending due to its large length.

[0039] Exemplarily, the length of the sleeve 1O is adjustable. For example, the sleeve 1O includes a plurality of sub-tubes spliced along the axial direction, and the interiors of the plurality of sub-tubes communicate. That is to say, the sub-tube includes a sub-tube lumen extending along an axis between two ends of the sub-tube, and the lumen 1O1 is composed of the communication of a plurality of sub-tube lumens. Exemplarily, the splicing method is implemented as a screw connection; that is, an external thread is formed on the outer edge surface of one end of the sub-tube, and an internal thread matching the external thread is formed on the inner wall of the other end. Exemplarily, the length of each sub-tube is the same and the outer edge surface is provided with length scales distributed along the axial direction. In another embodiment, the splicing method is implemented as plugging or bonding.

[0040] Combined with Figure 1 and Figure 2As can be seen from the example, a fixed connection portion 104 is provided at the end of the sleeve 1O corresponding to the detection port 103. Exemplarily, the fixed connection portion 104 is implemented as a card slot extending along the axial direction from the wall surface of the end of the sleeve 1O corresponding to the detection port 103. Further exemplarily, the size of the card slot is adapted to the size of the detection head 42 of the detector 40, so that the detection head 42 can be clamped in the card slot. In another embodiment, a rubber pad (not shown in the figure) is provided on the wall surface of the card slot. To prevent the detection head 42 of the detector 40 from being worn due to being repeatedly clamped in the card slot.

[0041] In Figure 1 and Figure 2 the example, the measuring member 20 is coaxially sleeved with the sleeve 1O. An angular scale is provided on the wall surface of the measuring member 20 facing the operation port 102 ( Figure 4 in). Among them, the fixed connection portion 104 is aligned with a preset scale line in the angular scale along the axial direction. Exemplarily, the preset scale line is implemented as the 0-degree scale line in the angular scale. Exemplarily, the measuring member 20 extends along the axial direction to form a first mounting hole 201, and the aperture of the first mounting hole 201 is adapted to the pipe diameter of the sleeve 1O. The sleeve 1O is coaxially and fixedly sleeved in the first mounting hole 201. In another embodiment, the preset scale line is implemented as a scale line of other degrees.

[0042] Through the above settings, when the operator uses the positioning assembly, the wire harness 41 of the detector 40 is inserted into the lumen 1O1 from the operation port 102, passes through the lumen 1O1 from the detection port 103, and the detection head 42 at the end of the wire harness 41 is clamped in the fixed connection portion 104 at the end of the sleeve 1O. Thus, when the positioning assembly rotates, it can drive the detection head 42 of the detector 40 to rotate, and when the operator drives the sleeve 1O to move up and down, it can also drive the detection head 42 of the detector 40 to move up and down.

[0043] Figure 3 As shown in Figure 1 is an enlarged view of A in. Combining Figure 1 and Figure 3 the example shows that the distance between the measuring member 20 and the detection port is adjustable. Exemplarily, the measuring member 20 is slidably sleeved on the sleeve 1O along the axial direction. The positioning assembly includes a fastener 30 (such as a bolt), and the fastener 30 is threadedly connected to the measuring member 20 in a direction perpendicular to the axial direction; and when the fastener 30 abuts against the sleeve 1O, the measuring member 20 is fixed to the sleeve 1O.

[0044] In this way, when it is necessary to adjust the distance between the measuring member 20 and the detection port, the operator makes the fastener 30 not abut against the sleeve 1O. After adding / removing a specified number of sub-tubes at the sub-tube at the proximal end, the measuring member 20 is slid in the direction close to / away from the proximal end to the sub-tube at the proximal end again. Then, the fastener 30 is made not to abut against the sleeve 1O again, so as to adjust the distance between the measuring member 20 and the detection port without taking out the positioning assembly from the inside of the part to be measured, so as to be able to detect the detection points at different depths inside the part to be measured, thereby improving the detection efficiency. Exemplarily, the end face of the fastener 30 abutting against the sleeve 1O is provided with a rubber pad (not shown in the figure) to prevent the metal fastener 30 from damaging the sleeve 1O. At the same time, rubber products can improve the fixing force between the fastener and the sleeve 1O. The measuring member 20 is also slidably sleeved on the sleeve 1O in a rotatable manner, so that the fixed connection portion can be aligned with any scale line in the angle scale.

[0045] In another embodiment, the sleeve 1O includes an inner tube and an outer tube; the measuring member 20 is coaxially and fixedly sleeved on the inner tube, and the outer tube is coaxially threadedly coupled to the inner tube; the detection port 103 is formed at the end of the outer tube away from the measuring member 20. In this way, the operator can rotate the outer tube forward and backward, and the inner tube gradually retracts into or extends out of the outer tube. At the same time, due to the self-locking property of the thread, the distance between the detection port 103 and the measuring member 20 along the axial direction is adjusted and maintained. Exemplarily, the inner tube includes an inner tube cavity, the outer tube includes an outer tube cavity, and the tube cavity 1O1 is formed by communicating the inner tube cavity and the outer tube cavity.

[0046] Figure 4 Shown is a top view schematic diagram of the measuring member in the embodiment of the present disclosure. In Figure 4 the example, the measuring member 20 includes an adjusting cylinder 21 and a measuring disk 22; the adjusting cylinder 21 is coaxially and fixedly sleeved with the sleeve, the measuring disk 22 is coaxially arranged on the adjusting cylinder 21, and the angle scale is formed on the wall surface of the measuring disk 22 facing the operation port. Exemplarily, the fastener is threadedly coupled to the adjusting cylinder 21 in a direction perpendicular to the axial direction, and the first mounting hole 201 is formed in the adjusting cylinder 21. And when the fastener abuts against the sleeve, the measuring member 20 is fixed to the sleeve. Exemplarily, by replacing the adjusting cylinder 21 with different outer diameters, the adjusting cylinder 21 is adapted to the size of the insertion port of the part to be measured to prevent the positioning assembly from shifting from the part to be measured. In another embodiment, the adjusting cylinder 21 and the measuring disk 22 can also be integrally formed to improve the integrity and overall strength of the measuring member 20.

[0047] Figure 5 The figure shows a cross-sectional schematic view of the detection device placed inside the part to be measured in another embodiment of the present disclosure. Figure 6 The figure shows a top view schematic of the detection device placed inside the part to be measured in another embodiment of the present disclosure. In Figure 5 and Figure 6 the example, the detection device includes the positioning assembly, the detector 40, and the marking portion 50. The detector 40 includes a wire harness 41 and a detection head 42. The wire harness 41 is threaded through the lumen 1O1, and the detection head 42 is clamped to the fixed connection portion 104. The marking portion 50 is provided on the part to be measured 100 and aligned with the preset scale line. For example, the marking portion 50 is provided on the wall surface of the part to be measured 100 facing the measuring disc 22. So as to facilitate aligning the marking portion 50 with the preset scale line.

[0048] Exemplarily, the lower wall surface of the measuring disc 22 and the upper wall surface of the part to be measured 100 in contact therewith are both parallel to the horizontal plane, so as to avoid the inclination of the sleeve deviating from the vertical direction due to the inclination of one of the lower wall surface of the measuring disc 22 or the upper wall surface of the part to be measured 100, and finally avoid the occurrence of inaccurate measurement results.

[0049] Exemplarily, when it is necessary to image the detection point for detection, the detector 40 is implemented as an endoscope, and the detection head 42 is implemented as including a camera. In another embodiment, when only the depression of the detection point needs to be detected, the detector 40 is implemented as an ultrasonic instrument, and the detection head 42 is implemented as a device capable of generating and receiving ultrasonic waves.

[0050] In summary, the present disclosure provides a positioning component and its detection device in an embodiment. The positioning component includes a sleeve and a measuring member. The sleeve includes a lumen extending along an axis between two ends of the sleeve, and an operation port and a detection port respectively provided at a proximal end and a distal end of the two ends and communicating with the lumen; a fixed connection portion is provided at the end of the sleeve corresponding to the detection port. The measuring member is coaxially sleeved with the sleeve; an angular scale is provided on the wall surface of the measuring member facing the operation port. Among them, the fixed connection portion is aligned with a preset scale line in the angular scale along the axis direction. The detection device includes the positioning component, a detector and a marking portion. The detector includes a wire harness and a detection head. The wire harness is passed through the lumen, and the detection head is clamped in the fixed connection portion. The marking portion is provided on the part to be measured and aligned with the preset scale line. Through the above settings, when the operator uses the positioning component, the wire harness of the detector is inserted into the lumen from the operation port, passes through the lumen from the detection port, and the detection head at the end of the wire harness is clamped in the fixed connection portion at the end of the sleeve. Thus, when the positioning component rotates, it can drive the detection head of the detector to rotate, and when the operator drives the sleeve to move up and down, it can also drive the detection head of the detector to move up and down.
