Description

Technical Field

[0001] This invention relates to the field of detection technology, and specifically to a fixing device and a rotating device. Background Technology

[0002] During the inspection process of testing equipment, optical inspection is typically performed on the workpiece using a configured inspection probe to obtain relevant information about the workpiece. The inspection probe is generally fixed in a preset position (such as on the machine base of the inspection equipment), and the relative position between the workpiece and the probe is adjusted by controlling the movement of the workpiece to complete the inspection operation. However, existing optical probes generally suffer from problems such as insecure installation, poor stability, and poor connection between the probe body and the wiring harness, which are largely related to the method of fixing the inspection probe. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide a fixing device and a rotating device using the fixing device, so as to achieve the purpose of stably fixing the detection probe.

[0011] The first pressing member and the first limiting member are arranged around the axis of the first channel. The first pressing member is used to cooperate with the first limiting member to clamp or release the probe body that passes through the first channel.

[0012] In one embodiment, the first pressing member has a connecting end and an opening end that are circumferentially opposite each other, and the connecting end of the first pressing member is integrally connected with the first limiting member;

[0013] A first locking structure is provided between the opening and closing end of the first pressing member and the first limiting member. The first locking structure is used to lock the opening and closing end of the first pressing member to the first limiting member in a separable manner.

[0014] In one embodiment, the second fixing mechanism includes:

[0015] A second positioning element, connected to the positioning connection mechanism, has a cutout structure that extends radially and penetrates the second positioning element axially; and

[0016] The second pressing member is inserted into the cut structure to form a second channel with the second positioning member. The second channel is used for the probe wire harness to pass through the second fixing mechanism. The second pressing member is configured to move radially within the cut structure to press or release the probe wire harness.

[0017] In one embodiment, a second locking structure is provided between the second positioning member and the second pressing member, the second locking structure being used to detachably lock the second pressing member and the second positioning member together.

[0018] In one embodiment, the first fixing mechanism and / or the second fixing mechanism are configured to connect the corresponding ends of the positioning coupling mechanism in a manner that allows for axial position adjustment relative to the positioning coupling mechanism.

[0019] In one embodiment, the positioning connection mechanism includes at least two connecting rods extending axially, and the first fixing mechanism and the second fixing mechanism are respectively connected to the connecting rods in a manner that allows them to move relative to each other axially; the at least two connecting rods are arranged at intervals in a manner that allows them to circumferentially surround the probe body and the probe harness.

[0020] In one embodiment, a position adjustment mechanism is further included, the position adjustment mechanism comprising:

[0021] The third positioning element has a third channel extending axially, and the first fixing mechanism passes through the third channel; and

[0022] An adjusting member is mounted on the third positioning member in a manner that allows it to move radially relative to the third positioning member, so as to support and push the first fixing mechanism to move, thereby realizing the position adjustment of the first fixing mechanism within the third channel.

[0023] In one embodiment, the number of adjusting members is set to at least two, and the at least two adjusting members include at least one first adjusting member and at least one second adjusting member;

[0024] The first adjusting member and the second adjusting member move in directions that are orthogonal to each other, or the first adjusting member and the second adjusting member are arranged radially opposite to each other.

[0025] In one embodiment, a wire harness protection mechanism is further included, arranged axially on the side of the second fixing mechanism opposite to the first fixing mechanism; the wire harness protection mechanism has a fourth channel arranged radially through it, the fourth channel being used for the probe wire harness to pass through the wire harness protection mechanism.

[0026] According to a second aspect, one embodiment provides a rotating device, comprising:

[0027] Support components;

[0028] A fixing member is used to fix a detection probe having a probe body and a probe wire harness, wherein the fixing member adopts the fixing device described in the first aspect;

[0029] A support member has a fifth channel extending axially, and a fixing member is arranged through the fifth channel and fixed to the support member; and

[0030] A driving member is fixed to the support member, and the power end of the driving member is coupled to the bearing member. The driving member is configured to drive the bearing member to rotate the fixing member around the axis of the fifth channel.

[0031] In one embodiment, the system further includes a second limiting member and a third limiting member. The second limiting member is fixed to the support member, and the third limiting member is fixed to the carrier member. The third limiting member is capable of abutting against the second limiting member when the carrier member rotates to a preset position, thereby preventing the carrier member from rotating; and / or

[0032] It also includes a first detection element and a second detection element. The first detection element is fixed to the support element, and the second detection element is fixed to the carrier element. The first detection element and the second detection element cooperate with each other to sense and obtain the position information of the carrier element.

[0033] The fixing device according to the above embodiment includes a positioning and connecting mechanism, a first fixing mechanism for fixing the probe body, and a second fixing mechanism for fixing the probe wiring harness. One end of the positioning and connecting mechanism is connected to the first fixing mechanism in the axial direction, and the other end is connected to the second fixing mechanism, so that the first fixing mechanism and the second fixing mechanism are axially spaced and fixedly connected. By using the positioning and connecting mechanism to fix the two fixing mechanisms in an axially spaced manner, a constant axial distance can be maintained between the two fixing mechanisms. By positioning and fixing the probe body and the wiring harness respectively through the two fixing mechanisms, a two-point fixing of the probe can be achieved. This ensures the stability and firmness of the probe fixing and avoids problems such as poor contact or even separation between the probe body and the wiring harness due to wire harness pulling or tangling. At the same time, the wiring harness protection mechanism, etc., prevents wire tangling while allowing the probe to rotate. Attached Figure Description

[0046] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0047] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0048] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0049] The terms “axial,” “radial,” and “circumferential” used in this article are three different directions defined based on the structural contour of the fixing device itself or when the fixing device is used to position and fix the detection probe. “Axial” can be understood as the length direction of the fixing device, or the direction of the axis of the probe body (or the extension direction of the axis of the probe body). Correspondingly, “radial” refers to the direction perpendicular to “axial”, and “circumferential” refers to the direction around “axial”.

[0050] The fixing device provided in this application utilizes a positioning and connecting mechanism to fix a first fixing mechanism and a second fixing mechanism, allowing them to be axially spaced relative to each other. This enables the first fixing mechanism to position and fix the probe body of the detection probe, and the second fixing mechanism to position and fix the probe wiring harness, achieving a two-point positioning and fixing of the detection probe. While ensuring the detection probe is firmly fixed, it effectively avoids the influence of factors such as pulling or twisting of the wiring harness on the connection structure between the probe body and the probe wiring harness, preventing problems such as poor connection between the wiring harness and the body, or even detachment.

[0051] In addition, by optimizing the structure of the fixing device, it is possible to ensure that the probe body has a certain rotational movement without wire entanglement, so as to solve the fixing and wire winding problems of long straight detection probes and meet different detection needs.

[0052] Please see Figures 1 to 5 and combined Figure 6 and Figure 7 One embodiment provides a fixing device that can be used to position and fix long and straight detection probes; the fixing device includes a first fixing mechanism 10, a second fixing mechanism 20, a positioning and connecting mechanism 30, and a wire harness protection mechanism 40, which are described in detail below.

[0053] Please see Figures 1 to 3 and combined Figure 6 and Figure 7The first fixing mechanism 10 is mainly used to position and fix the probe body a (hereinafter referred to as probe body a) of the detection probe. In one embodiment, the first fixing mechanism 10 adopts an integral structure, including an integrally formed first positioning member 11, a first limiting member 12, and a first pressing member 13. The outline of the first positioning member 11 is roughly cylindrical, and a through hole structure is provided axially on the first positioning member 11. For ease of distinction and description, this through hole structure is defined as the first channel 10a. The first limiting member 12 and the first pressing member 13 are arranged axially on one side of the first positioning member 11 (e.g., arranged on...). The first positioning member 11 is axially opposite to the second fixing mechanism 20, and the two face each other around the axis of the first channel 10a to form another through hole structure coaxially communicating with the first channel 10a between them; wherein, the first limiting member 12 is fixedly connected to the first positioning member 11, and the first pressing member 13 is structurally separated from the first positioning member 11; specifically, the first pressing member 13 has two opposite ends in the circumferential direction, one end of which is a connecting end that is integrated with the first limiting member 12, and the other end is an opening and closing end that can move and open relative to the first limiting member 12.

[0054] When the probe body a passes through the through hole structure formed by the first limiting member 12 and the first pressing member 13 through the first channel 10a, the opening and closing end of the first pressing member 13 can be fixed to the first limiting member 12 by locking members such as screws or other fixing structures (such as buckle structures). Thus, the probe body a is clamped and fixed by the cooperation of the first pressing member 13 and the second limiting member 12, thereby completing the assembly and fixation of the probe body a on the first fixing mechanism 10. The probe body a can be released or the tightness of the probe body a can be adjusted by changing the relative position (such as the distance) between the opening and closing end of the first pressing member 13 and the first limiting member 12.

[0055] It should be noted that by arranging the first limiting member 12 and the first pressing member 13 axially on one side of the first positioning member 11, it is also beneficial to extend the connection distance between the probe body a and the first fixing mechanism 10, thereby improving the stability of the probe body a being clamped and fixed. In addition, in specific implementations, the dimensions of the first channel 10a (such as the inner diameter, the cross-sectional profile shape of the hole, etc.) can be close to or the same as those of the probe body a, so that the probe body a can be adapted and combined with the first positioning member 11 and even the first fixing mechanism 10 through the first channel 10a, further enhancing the stability and firmness of the probe body a being fixed.

[0056] In another embodiment, the first fixing mechanism 10 can also be a split structure, such as the first limiting member 12 and the first positioning member 11 being integrally formed, or being fixed together by means of fasteners such as screws; while the first pressing member 13 is a separable structure from both the first positioning member 11 and the first limiting member 12. When it is necessary to fix the probe body a to the first positioning member 11, the connecting end and the opening end of the first pressing member 13 are fixed to the first limiting member 12 by means of relevant fasteners or fixing structures, thereby achieving the clamping and fixing of the probe body a.

[0057] In other embodiments, the first limiting member 12 and the first pressing member 13 may be omitted. Instead, fasteners such as locking screws can replace the functions of the first limiting member 12 and the first pressing member 13 by using a channel that is radially provided on the first positioning member 11 and passes through the first channel 10a. That is, the fastener is rotatably screwed into the radial channel of the first positioning member 11. By tightening the fastener, the end of the fastener presses against the probe body a that passes through the first channel 10a, which can also achieve the fixation or release of the probe body a.

[0058] Please see Figures 1 to 3 and combined Figure 6 and Figure 7 The second fixing mechanism 20 and the first fixing mechanism 10 are arranged axially at intervals. Specifically, the second fixing mechanism 20 is arranged axially on the side of the first positioning member 11 facing away from the first limiting member 12 (together with the first pressing member 13). When the probe body a is fixed to the first fixing mechanism 10 by passing through the first fixing mechanism 10, the probe harness b of the detection probe (hereinafter referred to as probe harness b; based on the difference in the type of detection probe, probe harness b can specifically refer to the optical fiber bundle, cable bundle, etc. connected to the probe body a) can be positioned and fixed by the second fixing mechanism 20, so that the part where the probe harness b is connected to the probe body a is located between the second fixing mechanism 20 and the first fixing mechanism 10, thereby realizing the two-point fixation of the detection probe.

[0059] In one embodiment, please refer to Figures 1 to 3 The second fixing mechanism 20 includes a second positioning member 21 and a second pressing member 22. The second positioning member 21 has a roughly disc-shaped outline and a cut structure 20a is provided on the second positioning member 21. The cut structure 20a is provided through the second positioning member 21 axially and extends from the outline edge of the second positioning member 21 to a position close to the geometric center of the second positioning member 21. The outer outline of the second pressing member 22 is roughly the same as the shape of the cut structure 20a. It is inserted into the cut structure 20a in a way that allows it to move radially within the cut structure 20a, thereby forming a through-hole structure distributed axially between the second pressing member 22 and the second positioning member 21. For ease of distinction and description, this through-hole structure is defined as the second channel 20b.

[0060] With the probe harness b positioned so that it passes through the second fixing mechanism 20 via the second channel 20b, the size of the second channel 20b can be adjusted by manipulating the second pressing member 22 within the cut structure 20a. This allows for clamping and fixing of the probe harness b by applying pressure, or loosening and releasing the probe harness b, and adjusting the tightness of its fixation. In practice, fasteners such as screws or other fixing structures (such as clips) can be used to maintain the connection between the second pressing member 22 and the second positioning member 21.

[0061] In other embodiments, without considering the structural complexity of the fixing device and the ability to meet the fixing requirements of a specific scenario, the structure of the second fixing mechanism 20 can also be selected and configured with reference to the first fixing mechanism 10; all such details will not be elaborated further.

[0062] Please see Figures 1 to 3 and combined Figure 6 and Figure 7 The positioning and connecting mechanism 30 extends a certain length in the axial direction. One end of the mechanism is connected to the first fixing mechanism 10 (specifically, the first positioning member 11), and the other end is connected to the second fixing mechanism 20 (specifically, the second positioning member 21). On the one hand, the positioning and connecting mechanism 30 ensures that the first fixing mechanism 10 and the second fixing mechanism 20 maintain a suitable distance in the axial direction to achieve two-point fixing of the detection probe. On the other hand, the positioning and connecting mechanism 30 fixes the first fixing mechanism 10 and the second fixing mechanism 20 into one unit to avoid affecting the fixing effect of the detection probe due to relative positional displacement between the two after the detection probe is fixed.

[0063] In one embodiment, please refer to Figures 1 to 3 The positioning and connecting mechanism 30 includes two connecting rods 31 extending axially. One end of each connecting rod 31 is connected to a first positioning member 11, and the other end is connected to a second positioning member 21. When the detection probe is fixed to the first fixing mechanism 10 and the second fixing mechanism 20, the two connecting rods 31 are arranged at intervals around the probe body a and the probe wire harness b in the circumferential direction. In a specific implementation, a first fixing hole 10b for fixing the end of the connecting rod 31 can be provided on the outer periphery of the first positioning member 11 at the first channel 10a. The first fixing hole 10b can be configured as a threaded hole structure to realize the disassembly, assembly, or adjustment of the connecting rod 31 and the first fixing mechanism 20 by screwing. On the outer periphery of the second positioning member 21 at the second channel 20b, a second fixing hole 20c for fixing the other end of the connecting rod 31 can be provided. The second fixing hole 20c can be configured as a through stepped hole structure, and the corresponding end of the connecting rod 31 is adapted to the contour shape of the second fixing hole 20c.

[0064] When the first fixing mechanism 10 and the second fixing mechanism 20 are fixedly connected by the connecting rod 31, one end of the connecting rod 31 can be inserted into the first fixing hole 10b, and the depth of the connecting rod 31 inserted into the first fixing hole 10b can be adjusted by rotating the connecting rod 31 or the first positioning member 11; while the other end of the connecting rod 31 is arranged through the second fixing hole 20c. Utilizing the structural matching relationship between this end and the second fixing hole 20c, and with the cooperation of fastening accessories such as nuts, the connecting rod 31 is finally locked between the first fixing mechanism 10 and the second fixing mechanism 20, and a suitable axial distance is maintained between them (it should be noted that this axial distance is determined by the depth of the connecting rod 31 inserted into the first fixing hole 10b). Of course, in specific implementations, the number of connecting rods 31 can also be set to three, four, or other numbers. It is best that multiple connecting rods 31 are spaced apart and evenly arranged around the detection probe or the first channel 10a, which is beneficial to maintaining the structural stability after the first fixing mechanism 10 and the second fixing mechanism 20 are fixedly connected.

[0065] In other embodiments, the first fixing hole 10b can also be configured as a smooth blind hole structure, so that the end of the connecting rod 31 can be inserted into the first fixing hole 10b at a fixed depth, thereby combining and fixing the two fixing mechanisms at a fixed distance. Alternatively, the positioning connection mechanism 30 can also adopt other structural constructions, such as strip-shaped plates, etc. For this type of positioning connection mechanism 30, it can be connected to the first fixing mechanism 10 and the second fixing mechanism 20 in a detachable manner such as screws or buckles. In all these cases, the key point is to ensure that the first fixing mechanism 10 and the second fixing mechanism 20 can be fixedly connected as one unit, and that the distance or relative position between the two fixing mechanisms can remain stable in a certain state (such as after the detection probe is fixed).

[0066] Based on this, by using the first fixing mechanism 10 and the second fixing mechanism 20 to position and fix the probe body a and the probe wire harness b respectively, the connection position of the detection probe components (such as the weak point where the probe wire harness b is connected to the probe body a) is located between the two fixing mechanisms, forming a two-point fixation of the detection probe; and by using the positioning connection mechanism 30 to fix the two fixing mechanisms, it can be ensured that the fixed part of the detection probe maintains good structural stability.

[0067] On the one hand, it can position and fix the detection probe in a preset position, such as on an optical inspection device, ensuring the structural stability and firmness of the detection probe after it is fixedly installed. On the other hand, based on the structural combination relationship between the first fixing mechanism 10, the second fixing mechanism 20 and the positioning connection mechanism 30, the fixing device (such as the first fixing mechanism 10) can also be installed on the rotating mechanism. The rotating mechanism can be used to control the fixing device and the detection probe to rotate relative to the detection object, thereby meeting specific detection requirements. In this scenario, since the end of the probe harness b connected to the probe body a is fixed to the probe body a by the fixing device, when other parts of the probe harness b are entangled, pulled, twisted or other changes occur, the connection between the probe harness b and the probe body a can always maintain good structural stability, and it is not easy for problems such as poor connection or even separation of the probe harness b and the probe body a to occur.

[0068] In one embodiment, please refer to Figure 2 A first locking structure is provided between the opening and closing ends of the first limiting member 12 and the first pressing member 13. The first locking structure is mainly used to lock the opening and closing ends of the first pressing member 13 to the first limiting member 12 in a separable manner. Specifically, the first locking structure includes a third fixing hole 10c and a fourth fixing hole (not shown in the figure). The third fixing hole 10c is provided to pass through the opening and closing ends of the first pressing member 13 in the direction (such as radial or circumferential) where the first limiting member 12 and the first pressing member 13 face each other. The fourth fixing hole is provided at the position of the first limiting member 12 corresponding to the third fixing hole 10c. In this way, with the cooperation of fasteners such as screws, the first locking structure can be used to lock the first pressing member 13 to the first limiting member 12, or the relative position between the opening and closing ends of the first pressing member 13 and the first limiting member 12 can be adjusted by tightening the fasteners inserted into the fourth fixing hole, thereby realizing the adjustment of the tightness of the probe body a. Of course, depending on actual needs, the first locking structure can also adopt other structural forms, such as setting a bayonet structure on the first limiting member 12 and setting a buckle structure at the opening and closing end of the first pressing member 13, and fixing the first limiting member 12 and the first pressing member 13 through the buckle connection.

[0069] In one embodiment, please refer to Figure 3A second locking structure is provided between the second positioning member 21 and the second pressing member 22. The second locking structure is mainly used to lock the second pressing member 22 in the cut structure 20a in a detachable manner. Specifically, the first locking structure includes a fifth fixing hole 20d and a sixth fixing hole 20e. The fifth fixing hole 20d is provided on both sides of the cut of the second positioning member 21 in the cut structure 20a. The outline of the second pressing member 22 is roughly T-shaped. The sixth fixing hole 20e is provided through both ends of the transverse part of the second pressing member 22. Thus, with the cooperation of fasteners such as screws, the second locking structure can lock the second positioning member 21 and the second pressing member 22 into one piece. The size of the second channel 20b can be adjusted by the difference in the depth of the fasteners inserted into the fifth fixing hole 20d.

[0070] Please see Figure 1 and Figure 4 and combined Figure 6 One embodiment of the fixing device further includes a wire harness protection mechanism 40, which is axially arranged on the side of the second fixing mechanism 20 facing away from the first fixing mechanism 10, and the wire harness protection mechanism 40 and the second fixing mechanism 20 maintain a certain distance. It can also be understood that, with regard to the probe wire harness b, the wire harness protection mechanism 40 and the second fixing mechanism 20 are located at different positions of the probe wire harness b. The wire harness protection mechanism 40 can be used to fix the probe wire harness b or change the extension direction of the probe wire harness b. When the main body of the fixing device (i.e., the first fixing mechanism 10, the second fixing mechanism 20 and the positioning connection mechanism 30) is fixedly mounted on the rotating mechanism so that the main body of the fixing device can drive the probe body a and part of the probe wire harness b to rotate relative to the detection object, the cooperation between the wire harness protection mechanism 40 and the second fixing mechanism 20 can prevent the wire harness part located between the two or the wire harness part between the wire harness protection mechanism 40 and the probe body a from getting tangled.

[0071] Specifically, the wire harness protection mechanism 40 has a fourth channel 40a, which is radially disposed through the wire harness protection mechanism 40. The fourth channel 40a can be used to change the direction of the probe wire harness b's extension. For example, the probe wire harness b extending axially from the second fixing mechanism 20 can change to radial extension after passing through the fourth channel 40a, or the probe wire harness b can be simultaneously fixed to the wire harness protection mechanism 40. Thus, by using the wire harness protection mechanism 40 to change and / or fix the extension direction of the probe wire harness b, the probe wire harness b can be prevented from... To prevent wire entanglement, in a specific implementation, to ensure that the probe wire harness b can be smoothly introduced into the fourth channel 40a and pass through the wire harness protection mechanism 40 from the fourth channel 40a, a notch 40b is also provided on the wire harness protection mechanism 40 to extend axially. This notch 40b is connected to the fourth channel 40a so that the probe wire harness b can be introduced into the fourth channel 40a after passing through the notch 40b. This allows the probe wire harness b to maintain a sufficient contact distance with the wire harness protection mechanism 40, creating favorable conditions for effectively avoiding wire entanglement.

[0072] It should be noted that, Figure 1 The bold dashed line in the figure represents the extended arrangement path or direction of probe harness b when it passes through harness protection mechanism 40.

[0073] Please see Figure 1 and Figure 5 and combined Figure 6 and Figure 7 One embodiment of the fixing device also includes a position adjustment mechanism 50, which is mainly used to fix the main body of the fixing device (together with the detection probe) on the rotating mechanism to ensure that the rotation center of the detection probe (specifically, probe body a) is consistent with the rotation center of the rotating mechanism, thereby ensuring that the detection probe has the ability to rotate at a certain angle relative to the detection object to meet the detection requirements.

[0074] The position adjustment mechanism 50 includes a third positioning member 51, a first adjusting member 52, and a second adjusting member 53. The third positioning member 51 can be coupled to the power end of the rotating mechanism. A third channel 50a is provided axially through the first positioning member 50, and the first fixing mechanism 10 is arranged through or through the third channel 50a. The first adjusting member 52 and the second adjusting member 53 are installed on the third positioning member 51 in a manner that allows them to move radially relative to the third positioning member 51, and the movement directions of the two adjusting members are orthogonal to each other. Specifically, the first positioning member 51 is provided with through-hole structures that extend radially and penetrate to the third channel 50a. The first adjusting member 52 and the second adjusting member 53 are installed on the third positioning member 51 by screwing through the corresponding through-hole structures.

[0075] Taking the first adjusting member 52 as an example, when the first adjusting member 52 is screwed on and moved radially relative to the third positioning member 51 toward the center of the third channel 50a, the end of the first adjusting member 52 located in the third channel 50a can abut against and push the first fixing mechanism 10 (along with the second fixing mechanism 20, the positioning connecting mechanism 30, the probe body a, and the probe wire harness b, etc.) to move in the same direction. This changes the position of the first fixing mechanism 10 in the third channel 50a. By using the two adjusting members in different directions, the rotation center of the first fixing mechanism 10 (or the probe body a), the rotation center of the third positioning member 51, and the rotation center of the rotating mechanism can be kept consistent, avoiding an increase in the probability of wire tangling due to the near-eccentric rotation of the probe body a. Conversely, when the first adjusting member 52 (and / or the second adjusting member 53) is screwed on and gradually moved away from the first fixing mechanism 10 radially, the main body of the fixing device can be released, so that the main body of the fixing device and the position adjusting mechanism 50 can be disassembled and reassembled.

[0076] In another embodiment, the first adjusting member 52 and the second adjusting member 53 may also be arranged radially opposite to each other, so that they can resist and push or release the resistance from the two opposite sides of the first fixing mechanism 10; or, the first adjusting member 52 and the second adjusting member 53 may also be arranged on one side of the third positioning member 51 in the axial direction, arranged radially opposite to each other, and mounted on the third positioning member 51 in an adjustable position, thereby clamping and fixing the first fixing mechanism 10 to the third positioning member 51.

[0077] In other embodiments, the first adjusting member 52 and the second adjusting member 53 may be selected, or multiple adjusting members similar to the first adjusting member 52 (or the second adjusting member 53) may be provided. The multiple adjusting members are arranged at intervals around the first fixing mechanism 10 (or the third channel 50a) in a circumferential direction, or arranged in pairs opposite each other, so as to achieve precise adjustment of the position of the first fixing mechanism 10 in the third channel 50a by utilizing the cooperation of the multiple adjusting members.

[0078] Please see Figure 6 and Figure 7 and combined Figures 1 to 5 This application embodiment also provides a rotating device that can be used to realize the rotation and position holding of the detection probe within the range of 0-360°. With the help of this rotating device, the detection probe has the ability to change and adjust the detection position (or orientation) relative to the detection object to meet different detection needs. The rotating device includes a support member 60, a fixing member, a bearing member 70, a driving member 80, and other components as needed. The following is a detailed description.

[0079] Please see Figure 6 and Figure 7The support member 60 is fixedly installed at a preset position (such as on a testing device or on a device around the testing device). The carrier member 70 has a fifth channel 70a that is axially through. The drive member 80 adopts a power output element such as a motor that can output rotational motion. The body of the drive member 80 is fixedly installed on the support member 60, and the power end of the drive member 80 is coupled to the carrier member 70. For example, the power coupling connection is made through a gear transmission assembly, so that the carrier member 70 can be driven to rotate relative to the support member 60 around the axis of the fifth channel 70a. The fixing member adopts the fixing device of any of the above embodiments. The fixing member is arranged through the fifth channel 70a and is fixedly connected to the carrier member 70.

[0080] Specifically, the positioning and connecting mechanism 30 and the detection probe are arranged through the fifth channel 70a, such that the first fixing mechanism 10 and the second fixing mechanism 20 are located on opposite sides of the first channel 70a or the carrier 70. In this case, the position adjustment mechanism 50 can be used to fix the device and the detection probe in an axial manner by stacking them, thereby completing the fixed assembly of the fixing device and the detection probe (at this time, the wire harness protection mechanism 40 is located at the end of the second fixing mechanism 20 away from the carrier 70). Simultaneously, the position of the main body of the fixing device and the detection probe is adjusted using the structural configuration of the position adjustment mechanism 50, ensuring that their axes are aligned with or coincide with the rotation center of the carrier 70. Of course, in embodiments where the position adjustment mechanism 50 is omitted, the first fixing mechanism 10 can also be directly fixed onto the carrier 70, ensuring that the rotation centers of both are aligned.

[0081] Taking the hole structure on the workpiece to be inspected as an example, in the specific application of the rotating device, after the detection probe is fixed, the probe body a can be inserted into the hole structure of the workpiece to be inspected, so that the signal transmitting and receiving end of the probe body a and the hole structure face each other radially; by controlling the driving component 80, the fixing device can drive the probe body a to rotate around the axis of the fifth channel 70 (or its own axis) in the hole structure (such as within the range of 0-360°), so as to achieve comprehensive detection of the hole structure and ensure the accuracy of the hole structure detection.

[0082] In one embodiment, please refer to Figure 7The rotating device also includes a second limiting member 90a and a third limiting member 90b. The second limiting member 90a is fixedly disposed at a certain position on the support member 60 (such as a 0° or 360° angle position) along the rotation trajectory of the carrier member 70, while the third limiting member 90b is fixedly disposed at the contour edge of the carrier member 70. When the driving member 80 drives the carrier member 70 to rotate the fixing device and the detection probe to a preset position (i.e., the position of the second limiting member 90a), the third limiting member 90b will abut against the second limiting member 90a. By acquiring the relevant signal at this time, the driving member 80 can be controlled to stop outputting power or change the power output direction (such as forward and reverse rotation) in a timely manner, thereby preventing the carrier member 70 and the like from continuing to rotate, so as to avoid problems such as invalid movement or wire entanglement.

[0083] In one embodiment, please refer to Figure 7 The rotating device also includes a first detection element 90c and a second detection element 90d. Multiple first detection elements 90c and 90d can be used. For example, multiple first detection elements 90c are arranged at intervals on the support 60 along the rotation trajectory of the carrier 70, while the second detection elements 90d are fixedly mounted on the carrier 70. When the carrier 70 drives the second detection elements 90d to rotate synchronously, the positional arrangement of the first detection elements 90c and their cooperation with the second detection elements 90d can be used to sense and acquire the positional information of the carrier 70 (or the signal transceiver of the probe body a), such as the angle or orientation information of the signal transceiver of the probe body a relative to the object being detected. Based on this, the cooperation of the first detection elements 90c and the second detection elements 90d facilitates precise control of the rotational stroke of the carrier 70 or the probe body a, meeting detection requirements. In specific implementations, the first detection elements 90c and 90d can be equipped with position sensing devices such as photoelectric sensors, depending on the actual situation.

[0084] It should be noted that, Figure 7 The thick solid line with an arrow in the middle represents the carrier 70 (or the rotation direction of the detection probe).

[0085] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
