[0044] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] The present application discloses a detection device for detecting a target position of a component. The target position may be a hole structure or other structure on the component. The hole structure may be a threaded hole.

[0046] Among them, refer to Figure 1 and Figure 2 The detection device includes a bracket 100, a driving assembly 200, a plurality of detection heads 400 and a connecting rod 300 arranged in the same number as the detection heads 400, wherein the driving assembly 200 is arranged on the bracket 100, and the driving assembly 200 has a driving portion that can slide axially relative to the bracket 100; the plurality of detection heads 400 are arranged around a preset axis and are all movably connected to the bracket 100; the connecting rods 300 arranged in the same number as the detection heads 400 are arranged around the preset axis, one end of each connecting rod 300 is rotatably connected to the driving portion, and the other end is rotatably connected to the corresponding connecting rod 300, wherein the axial direction of the preset axis is consistent with the driving direction of the driving portion; wherein each detection head 400 is suitable for the driving portion to move toward a position of the preset axis through the driving force of the connecting rod 300.

[0047] The preset axis can be understood as a virtual axis located at the center of each detection head 400 and the connecting rod 300; when the detection device detects the target position of the component, the target position is exactly on the path of the preset axis. If the target position is a threaded hole, the preset axis is exactly the center axis of the threaded hole.

[0048] Specifically, if the driving part of the driving assembly 200 moves in the direction of approaching the component along the preset axis, the driving part drives the ends of each connecting rod 300 to move synchronously, each connecting rod 300 rotates relative to the driving part and the detection head 400, and drives each detection head 400 to slide or rotate relative to the bracket 100, and each detection head 400 moves synchronously toward a position of the preset axis, thereby, the overall spacing between each detection head 400 is reduced, and the overall detection range of each detection head 400 is reduced, so that threaded holes with smaller hole positions can be detected. If the driving part of the driving assembly 200 moves in the direction of moving away from the component along the preset axis, the driving part drives the ends of each connecting rod 300 to move synchronously, each connecting rod 300 rotates relative to the driving part and the detection head 400, and drives each detection head 400 to slide or rotate relative to the bracket 100. Because the sizes of the above-mentioned identical components are consistent and the connection positions with other components are consistent, each detection head 400 moves synchronously away from the preset axis, thereby, the overall spacing between each detection head 400 is increased, and the overall detection range of each detection head 400 is increased, so that threaded holes with larger hole positions can be detected.

[0049] As can be seen from the above, compared with the existing detection device, which is only suitable for detecting threaded holes of one size. However, in the present application, the overall spacing between the detection heads 400 can be adjusted by manipulating the drive assembly 200, so that the detection device can be adapted to the detection of threaded holes of various sizes when used. Obviously, compared with the prior art that requires the configuration of multiple types of detection devices, the present application only requires one type of detection device to complete the detection of multiple threaded holes, saving costs.

[0050] In one possible embodiment, referring to Figure 2 and Figure 3 , each detection head 400 is arranged on the bracket 100 in an inclined and sliding manner relative to the preset axis, and the head of each detection head 400 is arranged at a position facing the preset axis, that is, all facing the target position of the component to be assembled. Specifically, the driving part of the driving assembly 200 moves in a direction close to the component along the preset axis, and each connecting rod 300 pushes the connected detection head 400 to slide along the bracket 100 in an inclined manner toward the component, thereby, the overall spacing between each detection head 400 is reduced, and the overall detection range of each detection head 400 is reduced, so that threaded holes with smaller hole positions can be detected. Conversely, the driving part of the driving assembly 200 moves in a direction away from the component along the preset axis, and each connecting rod 300 pulls the connected detection head 400 to slide along the bracket 100 in an inclined manner toward the component, thereby, the overall spacing between each detection head 400 is increased, and the overall detection range of each detection head 400 is increased, so that threaded holes with smaller hole positions can be detected.

[0051] It can be understood that each detection head 400 is slidably arranged on the bracket 100. With this arrangement, during the adjustment of the overall spacing of each detection head 400, each detection head 400 is always oriented toward a position of a preset axis. More specifically, each detection head 400 always remains oriented toward the threaded hole of the component. Therefore, after the overall distance adjustment of each detection head 400 is completed, there is no need to adjust the spacing between the detection device and the component to ensure that the detection head 400 can be oriented toward the threaded hole. Therefore, the detection device is more convenient to use.

[0052] Instead of the detection head 400 being slidably disposed on the bracket 100, in other possible embodiments, each detection head 400 is rotatably disposed on the bracket 100 (not shown in the figure), and the rotation center axis is perpendicular to the preset axis. Specifically, the driving portion of the driving assembly 200 moves in the direction of the preset axis close to the component, and each connecting rod 300 pushes the head of the connected detection head 400 to move toward the preset axis, thereby, the overall spacing between each detection head 400 is reduced, and the overall detection range of each detection head 400 is reduced, so that threaded holes with smaller hole positions can be detected. Conversely, the driving portion of the driving assembly 200 moves in the direction of the preset axis away from the component, and each connecting rod 300 pulls the head of the connected detection head 400 to move away from the preset axis, thereby, the overall spacing between each detection head 400 is increased, and the overall detection range of each detection head 400 is increased, so that threaded holes with smaller hole positions can be detected. It should be noted here that after the detection head 400 is adjusted, the orientation position of each detection head 400 on the preset axis changes. Therefore, after the position adjustment of the detection head 400 is completed, it is also necessary to adjust the distance between the detection device and the component so that the orientation position of each detection head 400 is exactly located at the threaded hole of the component.

[0053] In order to enable each detection head 400 to be tilted and slidably set on the bracket 100 facing the component, in a further embodiment, the detection device also includes a plurality of first guide rail structures 500, and the first guide rail structures 500 are provided in equal number as the detection heads 400, and are arranged in sequence around the bracket 100, and each detection head 400 is respectively set on the first guide rail structure 500, and each detection head 400 is slidably set on the bracket 100 through the first guide rail structure 500.

[0054] Specifically, a plurality of positioning and mounting surfaces 131 are arranged at intervals around the preset axis on the side of the bracket 100. The positioning and mounting surfaces 131 are arranged in the same number as the detection head 400, and each positioning and mounting surface 131 is arranged to extend obliquely toward a position of the preset axis. The first guide rail structure 500 includes a first guide rail 510 and a first guide rail seat 520. The first guide rail seat 520 is fixedly arranged on the positioning and mounting surface 131 along the extension direction of the positioning and mounting surface 131. The first guide rail seat 520 is slidably arranged on the first guide rail 510, and the detection head 400 is connected to the first guide rail seat 520.

[0055] As can be seen from the above, the detection head 400 is slidably set on the first guide rail 510 by using the first guide rail seat 520, and is thereby slidably set on the bracket 100. Because the accuracy between the first guide rail 510 and the first guide rail seat 520 is relatively high, the first detection head 400 always accurately maintains a position setting toward the preset axis during the sliding process relative to the bracket 100. More specifically, the detection head 400 always accurately maintains facing the threaded hole so as to be able to better detect the threaded hole. In addition, the bracket 100 is provided with a positioning mounting surface 131, and the first guide rail structure 500 is accurately assembled on the bracket 100 through the positioning mounting surface 131, thereby ensuring that the detection head 400 can accurately slide relative to the bracket 100, thereby ensuring the matching accuracy between each detection head 400, so as to accurately adjust the overall distance of each detection head 400.

[0056] In some embodiments, the bracket 100 is provided with a first stopper 132 and a second stopper 133 at intervals. The first stopper 132 is a protrusion provided on the bracket 100, and the protrusion is located on the side of the end of the first guide rail 510 close to the component. Thus, the first stopper 132 limits the detection head 400 from sliding excessively toward the product by limiting the first guide rail seat 520. Meanwhile, the second stopper 133 is a screw provided on the bracket 100, and the screw is located at the end of the first guide rail 510 away from the component, and is provided toward the first guide rail seat 520. Thus, the second stopper 133 limits the detection head 400 from sliding excessively away from the product by limiting the first guide rail seat 520. In summary, it can be seen that through the provision of the first stopper 132 and the second stopper 133, the first stopper 132 and the second stopper 133 enable the detection head 400 to slide within a set range, or more precisely, enable the detection head 400 to move within a controllable range, which is conducive to the adjustment of the overall position of the detection head 400.

[0057] In practical applications, in order to achieve synchronous driving of each connecting rod 300, the axial movement of the driving part can be achieved manually, such as manually adjusting the screw 210 to enable the driving part to generate an axial driving force; or, the axial movement of the driving part can be achieved automatically, such as switching the rotational driving force of a linear motor, electric push rod, cylinder or rotary motor into a linear driving force, etc., to automatically achieve the axial driving force of the driving part.

[0058] In one possible embodiment, referring to Figures 1 to 3The drive assembly 200 includes a screw rod 210, a nut sliding seat 220 and an operating handle 230, wherein the screw rod 210 is arranged along the direction of the preset axis and is rotatably connected to the bracket 100, and the central axis of the screw rod 210 coincides with or is arranged in parallel with the preset axis. The nut sliding seat 220 is slidably arranged on the inner side of the bracket 100 along the axial direction of the preset axis, and the inner end of the screw rod 210 is threadedly connected to the nut sliding seat 220, and the central part of the nut sliding seat 220 is the above-mentioned driving part. The ends of each connecting rod 300 are located around the threaded seat and are rotatably connected to the side of the nut mounting seat. The operating handle 230 is fixedly connected to the outer end of the screw rod 210, and the operating handle 230 can be operated to control the forward or reverse rotation of the screw rod 210.

[0059] In the specific application process, the staff controls the screw rod 210 to rotate forward or backward by operating the handle 230, and the screw rod 210 drives the nut sliding seat 220 to move along the axial direction of the screw rod 210, and the nut sliding seat 220 drives each connecting rod 300 to move, so as to drive the overall spacing of each detection head 400 to increase or decrease, so as to adapt to the detection of threaded holes of various sizes. It can be understood that, with the drive assembly 200 of the above structure, when the user stops rotating the screw rod 210, the nut sliding seat 220 can maintain the corresponding position of the screw rod 210, thereby ensuring that each connecting rod 300 remains in the adjusted position, and then each detection head 400 remains in the adjusted position. It can be seen that the drive assembly 200 has a self-locking function so that the detection head 400 can be maintained in the adjusted position. In addition, the thread of the screw rod 210 is dense enough, and the adjustment accuracy of the drive assembly 200 is high.

[0060] Further, refer to Figure 3 and Figure 4 The detection device further includes a locking assembly 700, which includes a clamping seat 710 and a locking member 720. The clamping seat 710 is fixed to the outer side of the bracket 100 by screws. The clamping seat 710 is provided with a clamping hole 711 for the screw rod 210 to pass through, and a notch 712 connected to the clamping hole 711 is provided on the side of the clamping seat 710. The tension of the notch 712 can be contracted to reduce the size of the clamping hole 711, so that the clamping seat 710 can clamp the screw rod 210. The locking member 720 is a bolt, which is threadedly connected to the clamping seat 710 at both sides of the notch 712. The staff can tighten the bolts to shrink the notch 712 of the clamping seat 710 to clamp the screw rod 210. Specifically, through the setting of the locking assembly 700, after the position adjustment of the detection head 400 is completed, the user can manually tighten the locking member 720, the tension of the notch 712 of the clamping seat 710 is contracted, and the clamping hole 711 of the clamping seat 710 is reduced to clamp the screw rod 210. When the clamping seat 710 clamps the screw rod 210, the rotation of the screw rod 210 can be restricted, thereby keeping the detection head 400 in the adjusted position.

[0061] In another possible embodiment, the drive assembly 200 includes a screw rod 210, a nut sliding seat 220 and a driving member (not shown in the figure), wherein the screw rod 210 is arranged along the direction of the preset axis and is rotatably connected to the bracket 100, and the central axis of the screw rod 210 coincides with or is arranged in parallel with the preset axis. The nut sliding seat 220 is slidably arranged on the inner side of the bracket 100 along the axial direction of the preset axis, the inner end of the screw rod 210 is threadedly connected to the nut sliding seat 220, and the central part of the nut sliding seat 220 is the above-mentioned driving part. The ends of each connecting rod 300 are located around the threaded seat and are rotatably connected to the side of the nut mounting seat. The driving member is fixedly arranged on the bracket 100, and the driving shaft of the driving member is transmission-connected to the outer end of the screw rod 210, for example, by a coupling connection, a gear assembly connection or a gear toothed belt connection. During the specific application process, the driving member automatically drives the screw rod 210 to rotate forward or reversely, and the screw rod 210 drives the nut sliding seat 220 to move along the axial direction of the screw rod 210. The nut sliding seat 220 drives each connecting rod 300 to move, so as to drive the overall spacing of each detection head 400 to increase or decrease, thereby adapting to the detection of threaded holes of various sizes.

[0062] In some embodiments, reference Figure 2 and Figure 3 The bracket 100 includes a first mounting portion 110, a second mounting portion 130 and a plurality of connecting rods 300. The first mounting portion 110 and the second mounting portion 130 are arranged at intervals along the direction of the preset axis, and a guide space for accommodating the nut sliding seat 220 is defined between the first mounting portion 110 and the second mounting portion 130. A plurality of support rods 120 are located around the nut sliding seat 220, one end of the support rod 120 is connected to the first mounting portion 110, and the other end is connected to the second mounting portion 130. The nut sliding seat 220 is slidably arranged between the connecting rods 300 along the axial direction of the preset axis. The outer end of the screw rod 210 is rotatably inserted into the first mounting portion 110, and is extended toward the side of the first mounting portion 110 away from the second mounting portion 130. The inner end of the screw rod 210 is inserted into the nut sliding seat 220 and is rotatably connected to the second mounting seat 130. The locking assembly 700 and the operating handle 230 are mounted on a side of the first mounting portion 110 away from the second mounting portion 130, and the detection heads 400 are arranged around the second mounting portion 130. It can be understood that the bracket 100 adopts the above-mentioned structural form, and the driving assembly 200 is compactly mounted on the bracket 100, which saves the space occupied by the detection head 400. Therefore, the detection device can be flexibly applied in a limited application space.

[0063] Furthermore, two connecting rods 300 are connected between each nut sliding seat 220 and each detection head 400 to ensure that the nut sliding seat 220 stably drives the detection head 400 to rotate or slide through the two connecting rods 300. Specifically, a plurality of protrusions 221 are arranged at intervals around the nut sliding seat 220, one end of a connecting rod 300 is rotationally connected to one side of the protrusion 221 in the circumferential direction and the other end is rotationally connected to one side of the detection head 400, one end of another connecting rod 300 is rotationally connected to the other side of the protrusion 221 in the circumferential direction and the other end is rotationally connected to the other side of the detection head 400, thereby, when the nut sliding seat 220 slides along the preset axis, the detection head 300 can be driven to slide stably through the two connecting rods 300. It can be understood that the nut sliding seat 220 adopts the above-mentioned structural form, and the two connecting rods 300 are respectively connected to the two sides of the protrusion 221 and the two sides of the detection head 400. The two connecting rods 300 can be conveniently connected to the nut sliding seat 220 and the detection head 400, and the whole is compactly assembled together, avoiding the detection device from occupying too much space.

[0064] In some embodiments, reference Figure 1 and Figure 5 The detection device further includes an annular light source 900, which is disposed on the bracket 100 and is located at the head position of the detection head 400. The central axis of the annular light source 900 coincides with the preset axis. The annular light source 900 is used to illuminate the target position of the component, for example, the annular light source 900 is used to illuminate the threaded hole of the component. It can be understood that when the detection head 400 is detecting the threaded hole, the lighting device can illuminate the threaded hole, so that the detection head 400 can clearly observe the internal situation of the threaded hole, thereby accurately detecting defects in the threaded hole.

[0065] The annular light source 900 may refer to an integrally formed annular light source 900 , or may be an annular light source 900 formed by arranging a plurality of sub-light sources in an annular shape.

[0066] Of course, if the detection head 400 has its own light source, when the detection head 400 detects the threaded hole, the light source of the detection head 400 illuminates the threaded hole, and there is no need to set the above-mentioned annular light source 900 for illuminating the threaded hole.

[0067] Furthermore, the detection device further includes a housing 800, which defines a communicating accommodation cavity and a light-through hole 810, wherein the detection head 400, the bracket 100, the connecting rod 300 and other components are all arranged in the accommodation cavity, each detection head 400 is arranged toward the light-through hole 810, the preset axis is arranged to coincide with the central axis of the light-through hole 810, and the annular light source 900 is arranged in the light-through hole 810. It can be understood that, through the arrangement of the housing 800, other components can be arranged in the accommodation cavity inside the housing 800, thereby ensuring the overall aesthetics; at the same time, the housing 800 facilitates the arrangement of the annular light source 900 by arranging the light-through hole 810, and the annular light source 900 is effectively protected.

[0068] The present application also discloses a hole structure detection device, including the above-mentioned detection device.

[0069] Among them, the detection device is equivalent to an execution end of the hole structure detection equipment, and the hole structure detection equipment also includes other structures such as manipulators, which are not limited in this application.

[0070] It is understandable that the hole structure detection device adopts the above detection device. Figure 1 and Figure 2 If the driving part of the driving assembly 200 moves in the direction of the preset axis approaching the component, the driving part drives the ends of each connecting rod 300 to move synchronously, each connecting rod 300 rotates relative to the driving part and the detection head 400, and drives each detection head 400 to slide or rotate relative to the bracket 100, and each detection head 400 moves synchronously toward a position of the preset axis, thereby, the overall spacing between each detection head 400 is reduced, and the overall detection range of each detection head 400 is reduced, so that threaded holes with smaller hole positions can be detected. If the driving part of the driving assembly 200 moves in the direction of the preset axis away from the component, the driving part drives the ends of each connecting rod 300 to move synchronously, each connecting rod 300 rotates relative to the driving part and the detection head 400, and drives each detection head 400 to slide or rotate relative to the bracket 100, and each detection head 400 moves synchronously away from the preset axis, thereby, the overall spacing between each detection head 400 is increased, and the overall detection range of each detection head 400 is increased, so that threaded holes with larger hole positions can be detected. It can be seen that the hole structure detection equipment adopts the above-mentioned detection device and can be adapted to the detection of threaded holes of various sizes.

[0071] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
