[0039] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0042] Furthermore, it is required that the application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0043] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0044] The embodiment of the present application provides a detection device. Figures 1 to 12 The detection device 10 provided in the embodiment of the present application includes: a first base 11, a second base 12, a moving part 13, a linear drive 14 and a detection component 15.

[0045] The second base body 12 is connected to the first base body 11 so as to rotate about the rotation axis 16. One of the second base body 12 and the movable member 13 is provided with a slide groove 121, and the other is provided with an inlay 131, which is embedded in the slide groove 121. The linear drive 14 is mounted on the first base body 11 and is in driving connection with the movable member 13. The linear drive 14 is capable of driving the movable member 13 to move, so as to apply a torque to the second base body 12 through the mating connection of the slide groove 121 and the inlay 131, so as to rotate the second base body 12 about the rotation axis 16.

[0046] refer to Figures 3 to 5 For example, the second base 12 is provided with a slide groove 121, and the moving member 13 is provided with an inlay 131. The linear drive 14 drives the moving member 13 provided with the inlay 131 to rise and fall, so that the second base 12 rotates around the rotating shaft 16.

[0047] Similarly, reference Figure 6 and Figure 7 The second base body 12 is provided with an inlay 131, and the moving member 13 is provided with a slide groove 121. The linear drive 14 can drive the moving member 13 provided with the slide groove 121 to rise and fall, so that the second base body 12 rotates around the rotating shaft 16.

[0048] The detection assembly 15 is disposed on the second base 12. It should be noted that the detection assembly 15 is a combination of components within the detection device 10 that perform detection functions. For example, if the detection device 10 is a flaw detector, the detection assembly 15 includes a radiation source and a detector. Of course, in other embodiments, the detection assembly 15 may also include other components, which are not listed here.

[0049] In this manner, in the embodiment of the present application, the second base body 12 is rotatably connected to the first base body 11 about the rotation axis 16. The linear actuator 14, by driving the movable member 13 to move, applies torque to the second base body 12 through the matingly connected slide slots 121 and inlays 131, causing the second base body 12 to rotate about the rotation axis 16. This eliminates the need for a rotary actuator at the rotation axis to drive the rotation of the second base body 12. Thus, by eliminating the rotary actuator used to drive the rotation of the second base body, the problem of the rotary actuator being easily damaged by bending moments can be resolved.

[0050] refer to Figures 3 to 7 In some embodiments, the movable member 13 can move along a first direction relative to the first base body 11. Specifically, the linear drive 14 installed on the first base body 11 can be used to drive the movable member 13 to move along the first direction relative to the first base body 11. The inlay 131 can move along a second direction relative to the slide groove 121, and the second direction is not parallel to the first direction. Specifically, the slide groove 121 extends along the second direction so that the inlay 131 embedded in the slide groove 121 moves along the second direction relative to the slide groove 121. Exemplarily, the angle between the second direction and the first direction is greater than or equal to 45 degrees and less than or equal to 90 degrees (that is, the angle value range is [45°, 90°]). In this way, the torque applied to the second base body 12 to rotate the second base body 12 around the rotating shaft 16 can be larger.

[0051] refer to Figure 3 In some embodiments, the linear drive 14 includes a rotary drive element 141, a threaded rod 142, and a threaded sleeve 143. Exemplarily, the rotary drive element 141 is a rotary motor or a hydraulic motor. The rotary drive element 141 is drivingly connected to the threaded rod 142, the threaded sleeve 143 is threadedly connected to the threaded rod 142, the threaded sleeve 143 is slidingly connected to the first seat 11, and the moving member 13 is connected to the threaded sleeve 143. In this way, in the process of the rotary drive element 141 driving the threaded rod 142 to rotate, the threaded sleeve 143 can be restricted from rotating so that the threaded sleeve 143 moves along the axial direction of the threaded rod 142, thereby driving the moving member 13 to move.

[0052] Exemplarily, threaded rod 142 is a screw, and threaded sleeve 143 is a nut. In some embodiments, a ball bearing is disposed between the screw and nut, so that the screw, nut, and ball bearings form a ball screw mechanism. Of course, in other embodiments, threaded rod 142 is provided with external threads, and threaded sleeve 143 is provided with internal threads, and the external threads and the internal threads are threadedly connected, thus forming a screw-nut mechanism.

[0053] refer to Figure 3In some embodiments, the linear actuator 14 further includes a first sliding fitting member 144 and a second sliding fitting member 145 that are slidably connected. The first sliding fitting member 144 is connected to the first base 11, and the threaded sleeve 143 is connected to the second sliding fitting member 145. For example, the threaded sleeve 143 is connected to the moving member 13, and the moving member 13 is connected to the second sliding fitting member 145, so that the threaded sleeve 143 is indirectly connected to the second sliding fitting member 145 via the moving member 13. In this way, the threaded sleeve 143 can be slidably guided by the connection between the threaded sleeve 143 and the second sliding fitting member 145 to prevent the threaded sleeve 143 from rotating with the threaded rod 142.

[0054] In some embodiments, the first sliding fitting member 144 is a slide rail, and the second sliding fitting member 145 is a slide seat.

[0055] In other embodiments, the linear drive 14 may be a linear motor, a hydraulic cylinder, or a pneumatic cylinder.

[0056] refer to Figure 1 、 Figure 2 、 Figure 8 and Figure 9 In some embodiments, the detection assembly 15 includes a ray source 151 and a detector 152 that are arranged opposite to each other, and in the direction of the connection between the ray source 151 and the detector 152, the rotating shaft 16 is located between the ray source 151 and the detector 152.

[0057] Exemplarily, the workpiece to be inspected can be arranged between the ray source 151 and the detector 152. The ray source 151 can emit rays, which can penetrate the workpiece and be received by the detector 152. The detector 152 can generate an image based on the received rays, and thus, it can be determined whether the workpiece is qualified based on the generated image. During the inspection process, it is sometimes necessary to adjust the angle of the acquired image. Therefore, the ray source 151 and the detector 152 can be rotated synchronously by driving the second base 12 to rotate, so as to adjust the ray source 151 and the detector 152 to a suitable angle. It should be noted that the ray source 151 and the detector 152 can be implemented based on existing technologies, and therefore the specific structure and working principle of the ray source 151 and the detector 152 will not be elaborated in the embodiments of the present application.

[0058] Combine Figure 10In some embodiments, the detection assembly 15 further includes a touch detection device 153. The touch detection device 153 includes a third base 1531, a cover 1532, and a position offset detector 1533. The third base 1531 is connected to the second base 12, the detector 152 is connected to the third base 1531, and the cover 1532 is located on the side of the detector 152 facing away from the third base 1531. The cover 1532 is elastically supported on the third base 1531, and the position offset detector 1533 is used to detect whether the cover 1532 moves relative to the third base 1531. In this way, if the cover 1532 is accidentally touched, the position offset detector 1533 can detect the movement of the cover 1532 relative to the third base 1531, so that the next action can be performed.

[0059] For example, the position deviation detector 1533 is connected to an audible and visual alarm. When the position deviation detector 1533 detects movement of the cover body 1532 relative to the third base body 1531, the position deviation detector 1533 turns on the power supply circuit of the audible and visual alarm, thereby causing the audible and visual alarm to operate and issue an alarm message, thereby alerting on-site personnel.

[0060] For example, the position shift detector 1533 is connected to the power supply circuit of the detection device 10. When the position shift detector 1533 detects that the cover 1532 moves relative to the third base 1531, the position shift detector 1533 short-circuits the power supply circuit, thereby shutting down the detection device 10.

[0061] refer to Figure 10 In some embodiments, the touch detection device 153 further includes a connecting post 1534 and an elastic element 1535. The connecting post 1534 is disposed through the third base 1531, one end of the connecting post 1534 is connected to the cover 1532, the elastic element 1535 is sleeved outside the connecting post 1534, and a stopper 15341 is provided on the end of the connecting post 1534 facing away from the cover 1532. The elastic element 1535 is sandwiched between the cover 1532 and the third base 1531, and the third base 1531 is sandwiched between the elastic element 1535 and the stopper 15341.

[0062] In this way, combined Figure 10 When the cover 1532 is accidentally touched, the cover 1532 moves toward the direction close to the detector 152. When the force of the accidental touch disappears, the cover 1532 moves away from the detector 152 under the elastic force of the elastic element 1535 and returns to its original position.

[0063] In some embodiments, the position offset detector 1533 includes a light emitter 15331 and a light receiver 15332, which are arranged opposite each other. The light emitter 15331 can emit a light signal toward the light receiver 15332. The cover 1532 is connected to a baffle 15321. When the cover 1532 is touched, the baffle 15321 moves with the cover 1532 to a blocking position between the light emitter 15331 and the light receiver 15332.

[0064] It should be noted that, combined with Figure 11 When the cover 1532 is in a normal position, the light transmitter 15331 sends a light signal to the light receiver 15332, which can be received by the light receiver 15332. Figure 12 When the cover 1532 is touched, the blocking piece 15321 moves with the cover 1532 to a blocking position between the light emitter 15331 and the light receiver 15332. The light signal emitted by the light emitter 15331 toward the light receiver 15332 cannot be received by the light receiver 15332. In this way, whether the cover 1532 moves relative to the third base 1531 can be determined by whether the light receiver 15332 detects the light signal.

[0065] For example, in some embodiments, the position offset detector 1533 may be a travel switch or a micro switch. When the cover 1532 is touched, a triggering portion of the travel switch or micro switch is triggered, thereby determining whether the cover 1532 is moving relative to the third base 1531.

[0066] Illustratively, a position offset detector 1533 is provided at a corner of the cover body 1532 , so as to improve the accuracy of detecting whether the cover body 1532 moves relative to the third base body 1531 .

[0067] For example, in this solution, the detector protection mechanism can consist of springs, a carbon fiber protective cover, a photoelectric switch, and a detector fixture. The carbon fiber protective cover is supported on the detector surface by four springs. When a workpiece is manually operated and collides with the protective cover, the cover will move and trigger the photoelectric limit switches (i.e., position deviation detectors 1533) located at the four corners, causing the device to stop, thus preventing further movement of the workpiece from damaging the detector.

[0068] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0069] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the embodiments of the present application, and the scope of the embodiments of the present application is defined by the appended claims and their equivalents.
