In the representation of the present disclosure, "a group" means two or more, unless otherwise clearly and specifically defined.

[0028] In order to clearly describe the present disclosure, components not related to the description are omitted, and the same reference numerals are given to the same or similar components throughout the specification.

[0029] Throughout the specification, when a device is said to be "connected" to another device, this includes not only the case of "direct connection" but also the case of "indirect connection" by placing other elements therebetween. In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0030] Although the terms first, second, etc. are used to represent various elements in this article in some examples, these elements should not be limited by these terms.

Terms defined in commonly used dictionaries are additionally interpreted as having meanings consistent with relevant technical literature and the message of the present disclosure, and shall not be overly interpreted as ideal or very formal meanings unless defined.

[0033] When the operator uses the detector to inspect the inside of the part to be tested, because the detector's harness is made of soft materials and has cables inside, the operator cannot accurately adjust the direction of the detector's detection head and insert the detector's detection head into the part to be tested, and cannot accurately control the detection head of the detector to move to a specified height and rotate to a specified angle. Ultimately, the operator cannot accurately obtain the specific location of the detection point, which in turn makes subsequent maintenance ineffective.

[0034] Based on the above problems, a positioning device is provided in the embodiment of the present disclosure, so that the operator can use the positioning device to accurately adjust the direction of the detection head and insert the detection head into the part to be measured. At the same time, the angle of the direction of the detection head and the depth of the detection head inserted into the part to be measured can be determined by the angle scale set on the scale member, so that the operator can determine the exact position of the detection point through the two data of angle and depth, thereby improving the efficiency and accuracy of detection.

[0035] Figure 1 , which is a schematic cross-sectional view of the overall structure of the positioning device in an embodiment of the present disclosure. Figure 2 FIG. 1 is a cross-sectional schematic diagram of the overall structure of the positioning device in the embodiment of the present disclosure in conjunction with the detector; Figure 1 and Figure 2 In the example, the positioning device includes a sleeve 10 , a scale member 20 and an indicator 30 .

[0036] The sleeve 10 includes a lumen 101 extending along an axis between the two ends of the sleeve 10, and an operation port 102 and a detection port 103 respectively arranged at the proximal end and the distal end of the two ends and connected to the lumen 101. It can be understood that the operation port 102 is for the wire harness 51 of the detector 50 to pass through, and the detection port 103 is for the wire harness 51 of the detector 50 to pass out. Exemplarily, the aperture of the lumen 101 is larger than the wire diameter of the wire harness 51 of the detector 50. Exemplarily, the sleeve 10 is implemented as being made of a hard material, such as an aluminum alloy. This is to avoid the sleeve 10 from bending due to its large length, which ultimately leads to inaccurate measurement results.

[0037] Figure 3 The figure shows a schematic top view of the overall structure of the positioning device in the embodiment of the present disclosure. Figure 1 and Figure 3In the example, the scale member 20 can be coaxially fixed and sleeved on the sleeve 10 so as to be relatively rotatable. The wall surface of the scale member 20 facing the operation port 102 is provided with an angle scale 21. Exemplarily, the scale member 20 is implemented as a measuring disk. The scale member 20 and the sleeve 10 are connected by a rotating member 40. For example, the rotating member 40 is implemented as a pair of annular baffles 41. The pair of annular baffles 41 are respectively coaxially fixed (for example, welded) and sleeved on the sleeve 10, and the scale member 20 is sleeved on the sleeve 10 and is located between and fits the pair of annular baffles 41. In this way, the position where the scale member 20 and the sleeve 10 rotate relative to each other is limited by the pair of annular baffles 41, so that the scale member 20 and the sleeve 10 can only rotate relative to each other, and displacement in other directions cannot occur. Thereby ensuring the accuracy of the measurement. Further illustratively, the scale member 20 forms a mounting hole along the extending direction of the axis. The sleeve 10 is inserted into the mounting hole. The annular baffle 41 has a avoidance hole that matches the size of the mounting hole.

[0038] In another embodiment, the pair of annular baffles 41 can also be integrally formed with the sleeve 10, that is, a groove is arranged around the outer edge of the sleeve 10, the scale member 20 is sleeved in the groove, and the size of the mounting hole is adapted to the size of the groove to avoid inaccurate measurement results caused by axial offset between the scale member 20 and the sleeve 10.

[0039] In another embodiment, the scale member 20 forms a mounting hole along the extension direction of the axis. The rotating member 40 is implemented as a bearing, the bearing is coaxially arranged in the mounting hole, and the sleeve 10 is coaxially arranged in the inner ring of the bearing. For example, the outer diameter of the bearing is interference-fitted with the mounting hole, and the sleeve 10 is sleeved in the inner ring of the bearing in an interference-fit manner.

[0040] Exemplarily, the length of the sleeve 10 is adjustable. For example, the sleeve 10 includes a plurality of sub-tubes spliced ​​along the axial direction, and the interiors of the plurality of sub-tubes are connected. In this way, the operator can adjust the length of the sleeve 10 by splicing different numbers of the sub-tubes. Secondly, the operator adjusts the distance between the detection port 103 and the scale member 20 in the axial direction by placing the scale member 20 at different positions of the sub-tubes through the rotating member 40. Thereby, the positions at different depths in the part to be tested can be detected. Preferably, the scale member 20 is arranged at the sub-tube corresponding to the proximal end.

[0041] Exemplarily, the sub-tube includes a sub-tube cavity extending along an axis between the two ends of the sub-tube. That is to say, the tube cavity 101 is composed of a plurality of the sub-tube cavities connected to each other. Exemplarily, the connection method is implemented as a screw connection; the outer edge surface of one end of the sub-tube forms an external thread, and the inner wall of the other end forms an internal thread that matches the external thread. Exemplarily, each of the sub-tubes has the same length and the outer edge surface is provided with a length scale distributed along the axis direction (not shown in the figure). In another embodiment, the splicing method can also be implemented as plug-in or bonding.

[0042] In another embodiment, the sleeve 10 includes an inner tube and an outer tube. The scale member 20 is coaxially 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 scale member 20. In this way, the operator can adjust the distance between the detection port 103 and the scale member 20 in the axial direction by rotating the outer tube forward and backward so that the inner tube gradually shrinks to or extends out of the outer tube. Thus, positions at different distances can be detected. Exemplarily, the inner tube includes an inner tube cavity, the outer tube includes an outer tube cavity, and the tube cavity 101 is composed of the inner tube cavity and the outer tube cavity connected. It can be understood by those skilled in the art that the positions of the inner tube and the outer tube can be interchanged, that is, the scale member 20 is coaxially fixedly sleeved on the outer tube, and the inner tube is coaxially threadedly coupled to the inner tube; the detection port 103 is formed at the end of the inner tube away from the scale member 20.

[0043] exist Figure 1 In the example, a fixed connection portion 11 is provided at the end of the sleeve 10 corresponding to the detection port 103. Exemplarily, the fixed connection portion 11 is implemented as a clamping port formed by a depression of the distal wall surface of the sleeve 10 along the axial direction. Further exemplarily, the size of the clamping port is adapted to the size of the detection head 52 of the detector 50 so that the detection head 52 will not fall off from the clamping port during the detection process. In another embodiment, a rubber pad (not shown in the figure) is provided on the wall surface of the clamping port. This prevents the detection head 52 of the detector 50 from being worn due to repeated clamping in the clamping port.

[0044] exist Figure 1 and Figure 3In the example, the indicating portion 30 is provided on the surface of the sleeve 10, and the scale line aligned along the angle scale 21 changes with the rotation of the sleeve 10. The fixed connection portion 11 and the indicating portion 30 are aligned or deviated by a preset angle along the axis. Exemplarily, the indicating portion 30 is provided on the outer surface of the sleeve 10 between the operating port 102 and the scale member 20. In this way, it is convenient for the operator to compare the indicating portion 30 with the angle scale 21 of the scale member 20, thereby improving the measurement efficiency. Exemplarily, the indicating portion 30 is implemented as an indicating block convexly provided on the surface of the sleeve 10. For example, the indicating block is implemented in the shape of an arrow and the surface is red.

[0045] Through the above arrangement, the operator can operate the sleeve 10 so that the fixed connection part 11 of the sleeve 10 can accurately adjust the direction of the detection head 52 and the insertion of the detection head 52 into the part to be measured. At the same time, the angle of the direction of the detection head 52 and the depth of the detection head 52 inserted into the part to be measured can be determined by the angle scale 21 set on the scale member 20, so that the operator can determine the exact position of the point to be measured through the angle and depth, thereby improving the efficiency and accuracy of the detection.

[0046] In another embodiment, the indicating portion 30 may also be formed on an annular baffle 41 that is in contact with the wall surface of the scale member 20 facing the operation port 102 .

[0047] In another embodiment, the indicator portion 30 is implemented as an indicator groove formed on the outer surface of the sleeve 10 or the wall surface of the scale member 20 facing the operation port 102 .

[0048] Figure 4 Shown in FIG. 1 is a schematic diagram of the overall structure of a detection device in yet another embodiment of the present disclosure.

[0049] In another embodiment of the present disclosure, a detection device 100 is provided, comprising the positioning device and a detector 50. The detector 50 comprises a wire harness 51 and a detection head 52. The wire harness 51 is passed through the lumen 101. The detection head 52 is clamped on the fixed connection portion 11.

[0050] When the operator uses the detector 50 for detection, the scale member 20 is attached to the surface of the part to be detected 200 and the detection port 103 of the sleeve 10 is inserted into the part to be detected 200. When the operator does not rotate the sleeve 10, the indicator 30 is aligned with a first value of the angle scale 21, such as the zero scale line. When the sleeve 10 rotates and drives the indicator 30 and the detection head 52 to rotate to a point to be detected, the indicator 30 is aligned with a second value of the angle scale 21. At this time, if the fixed connection part 11 and the indicator 30 are aligned along the axis, the angle where the second value is located is the angular direction of the point to be detected; if the fixed connection part 11 and the indicator 30 deviate from the preset angle along the axis, the difference between the second value and the preset angle is the angular direction of the point to be detected; and then the depth of the sleeve 10 inserted into the part to be detected 200 can be recorded to determine the specific position of the point to be detected, so as to facilitate the accurate positioning of the position in the later stage and improve the efficiency of the later maintenance.

[0051] Exemplarily, when it is necessary to image the detection point for detection, the detector 50 is implemented as a detector, and the detection head 52 is implemented as a camera. In another embodiment, if it is only necessary to detect whether the detection point is concave, the detector 50 is implemented as an ultrasonic instrument, and the detection head 52 is implemented as a device capable of generating and receiving ultrasonic waves.

[0052] In summary, a positioning device and a detection device thereof are provided in an embodiment of the present disclosure, wherein the positioning device comprises a sleeve, a scale and an indication portion. The sleeve comprises a lumen extending along an axis between the two ends of the sleeve, and an operation port and a detection port respectively arranged at the proximal end and the distal end of the two ends and connected to the lumen; a fixed connection portion is provided at the end of the sleeve corresponding to the detection port. The scale can be relatively rotatably coaxially fixedly sleeved on the sleeve; an angle scale is provided on the wall of the scale facing the operation port. The indication portion is provided on the surface of the sleeve, and the scale line aligned along the angle scale changes with the rotation of the sleeve. The fixed connection portion and the indication portion are aligned or deviated by a preset angle along the axis. The detection device comprises the positioning device, a wiring harness and a detection head. The wiring harness is passed through the lumen. The detection head is clamped on the fixed connection portion. Through the above arrangement, the operator can operate the sleeve so that the fixed connection part of the sleeve can accurately adjust the direction of the detection head and the insertion of the detection head into the part to be measured. At the same time, the angle of the direction of the detection head and the depth of the detection head inserted into the part to be measured can be determined by the angle scale set on the scale member, so that the operator can determine the exact position of the detection point through the angle and depth, thereby improving the efficiency and accuracy of the detection.

[0053] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure.
