Description
Technical Field
[0001] This invention relates to the field of bolt installation technology, and in particular to a hole-aligning tool and method for mounting plates. Background Technology
[0002] In power tower erection, numerous components are connected by bolts. However, high-tower operations pose significant risks, and rotating large bolts at heights is extremely difficult. Therefore, mechanical climbing equipment is often used to automate bolt tightening, as illustrated in patent application CN116279878A. However, when installing bolts between adjacent mounting plates in high towers, the mounting holes often align but are not perfectly aligned. Since the bolt and mounting hole dimensions are typically quite close, this makes it difficult for the bolt to pass through multiple mounting plates, hindering subsequent connection, installation, and fixation. Therefore, a tool and method for aligning mounting plates during high-tower operations is needed. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hole-aligning tool and method for mounting plates.
[0004] To solve the above problems, the present invention adopts the following technical solution: A mounting plate alignment tool includes a wedge structure for inserting and aligning holes, a vision structure for locating holes, an action component for controlling the movement of the wedge structure, a housing, and a controller. The wedge structure is slidably disposed inside the housing, with one end extending out of the housing. The controller and the action component are fixedly disposed inside the housing. The vision structure is disposed on the outside of the housing and is communicatively connected to the controller. The action component is drively connected to the wedge structure and is used to control the reciprocating motion of the wedge structure. The action structure is also communicatively connected to the controller. The vision structure is correspondingly disposed to the wedge structure, facing the direction of the outward extension movement of the wedge structure. The housing also has a clamping structure that cooperates with an external robotic arm.
[0005] Furthermore, the actuation component includes a motor; the motor is connected to the wedge structure via a gear set and a lead screw structure; wherein one gear in the gear set is coaxially fixed with the lead screw in the lead screw structure, and the wedge structure is threadedly engaged with the lead screw; both ends of the lead screw are rotatably connected to the outer casing.
[0006] Furthermore, the wedge structure includes a tensioning top wedge and a tensioning flap; wherein the upper and lower sides of the tensioning top wedge are set as inclined surfaces, so that one end of the tensioning top wedge forms a tip with a small cross-sectional area; tensioning flaps that slide and engage with the inclined surfaces are respectively provided on the upper and lower inclined surfaces of the tensioning top wedge; the tensioning top wedge and the lead screw are threaded together, and the tensioning top wedge passes through the front end plate in the outer shell; one end of the tensioning flap is inserted into a sliding hole provided inside the front end plate of the outer shell, the depth direction of the sliding hole is perpendicular to the movement direction of the tensioning top wedge; the other end of the tensioning flap is set as a tip.
[0007] Furthermore, the upper and lower inclined surfaces of the tensioning wedge are respectively provided with sliding grooves, and the tensioning flap is provided with sliding protrusions that cooperate with the sliding grooves, with the sliding protrusions embedded in the sliding grooves.
[0008] Furthermore, the tensioning flap is also provided with a connecting post that can be inserted into the front end plate. The front end plate is provided with a connecting hole corresponding to the connecting post. A second spring is also provided in the connecting hole, and the second spring pushes the tensioning flap against the tensioning wedge.
[0009] Furthermore, the outer shell is also provided with a slot for limiting the sliding of the wedge structure, and a groove block that mates with the slot is provided on the side where the wedge structure fits into the outer shell.
[0010] Furthermore, the wedge-shaped structure also includes a latch, which is elongated and embedded in a strip-shaped lock hole on the side of the tensioning wedge. The end of the latch away from the tip of the tensioning wedge is set as an outwardly inclined slope, which serves as a groove block that mates with the slot. The other end of the latch is set as an L-shaped bent structure. When the latch is in contact with the bottom of the lock hole, the slope extends out of the lock hole to mate with the slot, and the bent structure is hidden inside the lock hole.
[0011] Furthermore, the vision structure includes at least three lasers and a camera; the lasers are fixedly mounted on the housing, and the laser irradiation direction is parallel to the length direction of the lead screw; the lasers are arranged around the tension wedge; the camera faces the area irradiated by the lasers, and the camera is rotatably connected to the housing.
[0012] Furthermore, the clamping structure includes a universal coupling, a flexible front end, and a flexible handle; both ends of the universal coupling are connected to the flexible front end and the flexible handle respectively, the flexible front end is also fixedly connected to the outer shell, and the flexible handle is used for clamping with an external robotic arm; a first spring is also provided between the outer shell and the flexible handle; an inwardly extending clamping plate is provided inside the outer shell, the clamping plate is fixedly connected to the flexible front end, and the clamping plate also abuts against one end of the first spring, the first spring being sleeved between the flexible front end and the universal coupling.
[0013] A hole-setting method, based on the aforementioned hole-setting tool, includes the following steps: Step 1: An external robotic arm holds the alignment tool and moves it to the location near the mounting hole; Step 2: The controller activates the laser in the vision structure, irradiates the area, and forms the laser irradiation area on the mounting plate; Step 3: The camera captures an image of the laser-irradiated area on the mounting plate and determines whether the mounting hole is located within the line area of the laser-irradiated area. If it is located within the line area of the irradiated area, proceed to the next step; otherwise, adjust the movement position of the robot arm and return to Step 1. Step 4: The controller controls the movement of the motor in the motion assembly, controlling the tension wedge in the wedge structure to penetrate deeper into the mounting hole; Step 5: The side of the ramp surface of the latch tongue on the side of the tension wedge moves to the edge of the slot and is pressed down by the outer shell as it continues to move. One end of the bent structure in the latch tongue is lifted up due to the lever action and abuts against the mounting plate. Step 6: The camera acquires an image and detects that the latch is raised, indicating that the hole alignment operation on the mounting plate has been completed. The tension wedge is then retracted, and the process ends.
[0014] The beneficial effects of this invention are as follows: By setting up a movable wedge structure, in conjunction with motion components and vision structures, the system can automatically align the mounting holes on multiple mounting plates, facilitating subsequent bolt installation, avoiding manual intervention, and improving the safety of high-altitude operations. By setting a wedge structure including a tensioning top wedge and a tensioning flap, on the one hand, the end of the tensioning top wedge can easily enter the mounting hole, and on the other hand, in conjunction with the tensioning flap, it can abut against the edge of the mounting hole as much as possible, so that the mounting hole can be better aligned. By setting a locking tongue with a slot, it can both match the sliding direction of the tension wedge and lift the locking tongue after it has moved to a set stroke, thus preventing the tension wedge from moving forward. By setting the clamping structure including a universal coupling, a flexible front end and a flexible handle, and in conjunction with the first spring, it has the ability to bend and deform elastically. This allows for correction even when the threaded hole is not directly aligned, through the bending deformation generated by the entire clamping structure, making it easier to complete the alignment of the mounting hole. In addition, it can also play a certain role in elastic buffering when the wedge structure goes too deep into the mounting hole. By employing a hole-aligning method, the alignment of mounting holes on different mounting plates can be completed during high-altitude operations. Attached Figure Description

Detailed Implementation
[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0019] Example 1: like Figures 1-7As shown, a mounting plate alignment tool includes a wedge structure 1 for inserting and aligning holes, a vision structure 2 for positioning holes, an action component 3 for controlling the movement of the wedge structure 1, a housing 4, and a controller 5. The wedge structure 1 is slidably disposed inside the housing 4, with one end extending out of the housing 4. The controller 5 and the action component 3 are fixedly disposed inside the housing 4, with the controller 5 located near the lower part of the housing 4, and the action component 3 and the wedge structure 1 located near the upper part of the housing 4. The vision structure 2 is disposed on the outside of the housing 4 and is communicatively connected to the controller 5. The action component 3 is drively connected to the wedge structure 1 and is used to control the reciprocating motion of the wedge structure 1. The action structure is also communicatively connected to the controller 5. The vision structure 2 is correspondingly disposed to the wedge structure 1, with the vision structure 2 facing the direction of the outward extension movement of the wedge structure 1. The housing 4 is also provided with a clamping structure 6 that cooperates with an external robotic arm for gripping. When the wedge structure 1 is driven by the action component 3 and inserted into the mounting hole on the mounting plate, it can align the mounting holes between two or more mounting plates, making it easier to insert bolts and complete the threaded connection of the power tower.
[0020] The actuation component 3 includes a motor 31. The motor 31 is connected to the wedge structure 1 via a gear set 32 and a lead screw structure 33. The gear set 32 is located between the lead screw structure 33 and the motor 31, and is used to transmit the torque of the motor 31 to the lead screw structure 33. The gear set 32 includes three gears. One gear is coaxially fixed with the lead screw in the lead screw structure 33, another gear is driven on the front end plate 41, and the last gear is located on the output shaft of the motor 31. The gear on the front end plate 41 meshes with the other two gears to achieve transmission. The wedge structure 1 is threaded to the lead screw. The two ends of the lead screw are rotatably connected to the outer casing 4. In this example, the front end and rear end of the outer casing 4 are respectively provided with two parallel front end plates 41 and rear end plates 42. The lead screw is rotatably arranged between the front end plates 41 and the rear end plates 42. Through the meshing of the three gears in the gear set 32, the motor 31 drives the lead screw to rotate. After the lead screw rotates, it can drive the wedge structure 1 on the lead screw to reciprocate, completing the hole-aligning action.
[0021] The wedge structure 1 includes a tensioning wedge 11 and a tensioning flap 12. The upper and lower sides of the tensioning wedge 11 are set as inclined surfaces, so that one end of the tensioning wedge 11 forms a small-section "I"-shaped tip for easy insertion into the mounting hole. In this example, the tip of the tensioning wedge 11 faces the mounting hole of the mounting plate outside the outer casing 4. Tensioning flaps 12 are respectively provided on the upper and lower inclined surfaces of the tensioning wedge 11, which slide in conjunction with the inclined surfaces. The tensioning flaps 12 are used to prevent the tensioning wedge 11 from going too deep into the mounting hole when aligned, thus preventing damage to the edge of the mounting hole. The tensioning wedge 11 is threaded into the lead screw, and the end of the tensioning wedge 11 also protrudes through the front end plate 41 in the outer casing 4. The tensioning flaps 12... The other end is provided with a sliding structure that engages with a sliding hole 411 inside the front end plate 41 of the outer casing 4, so that the tensioning flap 12 also slides in engagement with the sliding hole 411 and slides along the depth direction of the sliding hole 411. The depth direction of the sliding hole 411 is perpendicular to the movement direction of the tensioning wedge 11, so that the tensioning flap 12 only moves up and down within the sliding hole 411 and does not move in the movement direction of the tensioning wedge 11. When the tensioning wedge 11 extends outward from the outer casing 4, the tensioning flaps 12 on the upper and lower sides of the tensioning wedge 11 move into the sliding hole 411 respectively, and conversely, the tensioning flaps 12 move towards the center line of the tensioning wedge 11. The other end of the tensioning flap 12 is provided with a pointed tip, which facilitates the tensioning flap 12 to enter the mounting hole on the mounting plate. The tensioning flap 12 is also provided with a connecting post 122 that inserts into the front end plate 41. The front end plate 41 is provided with a connecting hole 412 corresponding to the connecting post 122. A second spring 413 is also provided in the connecting hole 412. The second spring 413 pushes the tensioning flap 12 against the tensioning wedge 11, so that the tensioning flap 12 is kept in close contact with the upper and lower inclined surfaces of the tensioning wedge 11. In order to make the tensioning flap 12 fit the tensioning wedge 11 better, the side of the tensioning flap 12 facing the tensioning wedge 11 is also set as an inclined surface. Sliding grooves 111 are respectively provided on the upper and lower inclined surfaces of the tensioning wedge 11. A sliding protrusion 121 that cooperates with the sliding groove 111 is provided on the tensioning flap 12, and the sliding protrusion 121 is embedded in the sliding groove 111.
[0022] The outer shell 4 is also provided with a slot 43 for limiting the sliding of the wedge structure 1. The length direction of the slot 43 is consistent with the movement direction of the tensioning wedge 11. A groove block that cooperates with the slot 43 is provided on the side where the wedge structure 1 fits with the outer shell 4. The groove block is restricted to slide in the slot 43, which on the one hand prevents the wedge structure 1 from shaking up and down, and on the other hand prevents the groove block from leaving the area where the slot 43 is located, thereby limiting the movement range of the tensioning wedge 11.
[0023] The wedge structure 1 also includes a latch 13, which is elongated and fitted into an elongated locking hole 112 on the side of the tensioning wedge 11. One end of the latch 13 away from the tip of the tensioning wedge 11 is configured as an outwardly convex ramp 131, which in this example serves as a groove block that mates with the slot 43 on the outer casing 4. The other end of the latch 13 is configured as an L-shaped bent structure 132. When the latch 13 is in contact with the bottom of the locking hole 112, the ramp 131 extends out of the locking hole 112 and... The slot 43 fits, and the bent structure 132 is hidden inside the lock hole 112. At this time, the bent structure 132 in the latch 13 will not affect the wedge structure 1 from penetrating into the mounting hole. When the ramp surface 131 in the latch 13 moves to the end of the slot 43 on the outer shell 4, as the tension wedge 11 continues to move, the latch 13 is pressed down by the inner wall of the outer shell 4. At this time, the bent structure 132 at the other end of the latch 13 is lifted by the leverage force, which acts to hold against the edge of the mounting hole and prevent the tension wedge 11 from penetrating too deeply into the mounting hole. It should be noted that the position of the bent structure 132 in the latch 13 in the length direction of the tension wedge 11 corresponds to the end of the tensioning flap 12. The latch 13 can form a mutual cooperation with the tensioning flap 12 to prevent the tension wedge 11 from penetrating too deeply into the mounting hole and damaging the mounting hole structure. The latch 13 has a locking post on the back side of the side with the ramp 131, and a corresponding locking hole is provided in the locking hole 112 of the tension wedge 11. This allows the locking post to engage with the locking hole when the latch 13 is pressed down on the ramp 131, enhancing the load-bearing capacity of the latch 13 and ensuring it abuts against the edge of the mounting hole. In this example, a rotating shaft for rotatable connection is also provided inside the locking hole of the latch and the tension wedge. The rotating shaft passes through the latch and connects to the two side walls of the locking hole.
[0024] The visual structure 2 includes at least three lasers 21 and a camera 22. The lines connecting the irradiation points of the three or more lasers 21 can form a pattern. Based on the positional relationship between the pattern and the mounting holes, it is possible to determine whether the wedge structure 1 is initially aligned with the mounting holes. The lasers 21 are fixedly mounted on the housing 4, and the irradiation direction of the lasers 21 is parallel to the length direction of the lead screw. In this example, the lasers 21 irradiate towards the direction in which the tensioning wedge 11 extends out of the housing 4. The lasers 21 are arranged around the tensioning wedge 11, so that the irradiation points of the lasers 21 can surround the tensioning wedge 11. The camera 22 faces the irradiation point of the lasers 21. The camera 22 is rotatably connected to the housing 4, facilitating the adjustment of the camera 22's angle to adapt to the different distance requirements when the tensioning wedge 11 is used to align mounting holes of different diameters, ensuring that the camera 22 always faces the irradiation point of the lasers 21 on the mounting plate. In this example, the camera 22 is located on the outer side of the housing 4, near the lower part, for easy connection to the controller 5 located at the lower end inside the housing 4.
[0025] The clamping structure 6 includes a universal coupling 61, a flexible front end 62, and a flexible handle 63. Both ends of the universal coupling 61 are connected to the flexible front end 62 and the flexible handle 63, respectively. The flexible front end 62 is also fixedly connected to the outer shell 4. The flexible handle 63 is used for clamping with an external robotic arm. A first spring 64 is also provided between the outer shell 4 and the flexible handle 63. An inwardly extending clamping plate 44 is provided inside the outer shell 4. The clamping plate 44 is fixedly connected to the flexible front end 62 and abuts against one end of the first spring 64. The first spring 64 is fitted between the flexible front end 62 and the universal coupling 61. This allows for some correction through the bending deformation of the clamping structure 6 even when not directly aligned with the threaded hole, facilitating the alignment of the mounting hole. Additionally, it provides some elastic buffering when the wedge structure 1 extends excessively into the mounting hole. In this example, the clamping structure 6 passes through the rear end plate 42 of the outer shell 4 and enters the interior of the outer shell 4. It should be noted that the opening on the outer shell 4 is larger than the insertion surface of the clamping structure 6, thus providing space for the bending of the clamping structure 6. The flexible handle 63 includes two parts: one part is a flexible rod for connecting with the universal coupling 61, and the other part is a rigid T-shaped rod for clamping with the external robot arm, facilitating the robot arm to clamp the T-shaped rod stably without twisting.
[0026] Two photoelectric sensors 34 for detecting position are respectively provided on the corresponding positions of the lead screw structure 33 in the action component 3. A corresponding light shield 35 is also provided on the lead screw nut fixedly connected to the tension wedge 11 in the lead screw structure 33. The light shield 35, together with the photoelectric sensors 34, is used to control the maximum and minimum stroke of the tension wedge 11 to prevent the lead screw structure 33 from rotating excessively, causing the lead screw nut to reach both ends of the lead screw and damage other components at both ends.
[0027] A hole-setting method, based on the aforementioned hole-setting tool, includes the following steps: Step 1: An external robotic arm holds the hole-aligning tool and moves it to the location near the mounting hole; this step is usually achieved by existing tower climbing mechanical platforms, such as the device shown in the patent application publication number CN116279878A mentioned in the background art. Step 2: The controller activates the laser in the vision structure, irradiates the area, and forms the laser irradiation area on the mounting plate; Step 3: The camera captures an image of the laser-irradiated area on the mounting plate and determines whether the mounting hole is located within the line area of the laser-irradiated area. If it is located within the line area of the irradiated area, proceed to the next step; otherwise, adjust the movement position of the robotic arm and return to Step 1. It should be noted that the image recognition of the camera image uses existing recognition methods, such as relying on a trained image recognition model to complete the process. Step 4: The controller controls the movement of the motor in the motion assembly, controlling the tension wedge in the wedge structure to penetrate deeper into the mounting hole; Step 5: The side of the ramp surface of the latch tongue on the side of the tension wedge moves to the edge of the slot and is pressed down by the outer shell as it continues to move. One end of the bent structure in the latch tongue is lifted up due to the lever action and abuts against the mounting plate. Step 6: The camera acquires an image and detects that the latch is raised, indicating that the hole alignment operation on the mounting plate has been completed. The tension wedge is then retracted, and the process ends.
[0028] During implementation, a movable wedge structure, in conjunction with motion components and a vision system, automatically aligns mounting holes on multiple mounting plates, facilitating subsequent bolt installation, eliminating manual intervention, and improving safety during high-altitude operations. The wedge structure, including a tension wedge and a tensioning flap, allows the end of the tension wedge to easily enter the mounting hole, while the tensioning flap, in conjunction with the wedge, maximizes contact with the edge of the mounting hole, ensuring better alignment. A locking tongue with a slot allows it to move in the direction of the tension wedge's slide and, after reaching a set travel distance, to lift the locking tongue, preventing further movement. A clamping structure, including a universal coupling, a flexible front end, and a flexible handle, along with a first spring, provides elastic bending deformation. This allows for correction even when not directly aligned with the threaded hole, facilitating mounting hole alignment. It also provides a buffer when the wedge structure extends excessively into the mounting hole. Finally, a hole-aligning method is used to align mounting holes on different mounting plates during high-altitude operations.
[0029] The above description is merely a specific example of the present invention and does not constitute any limitation on the present invention. Obviously, those skilled in the art, after understanding the content and principles of the present invention, may make various modifications and changes in form and detail without departing from the principles and structure of the present invention; however, these modifications and changes based on the spirit of the present invention are still within the scope of protection of the claims of the present invention.

A method for aligning holes, characterized in that, Based on the hole-setting tool according to any one of claims 1 to 6, the hole-setting method includes the following steps: Step 1: An external robotic arm holds the alignment tool and moves it to the location near the mounting hole; Step 2: The controller (5) controls the laser (21) in the vision structure (2) to start, irradiate the laser, and form the laser irradiation area on the mounting plate; Step 3: The camera (22) acquires an image of the laser irradiation area on the mounting plate and determines whether the mounting hole is located within the line area of the irradiation area of the laser (21). If it is located within the line area of the irradiation area, proceed to the next step; otherwise, adjust the movement position of the robot arm and return to step 1. Step 4: The controller (5) controls the movement of the motor (31) in the action assembly (3) to control the tension wedge (11) in the wedge structure (1) to penetrate into the mounting hole; Step 5: The side of the ramp surface (131) of the locking tongue (13) on the side of the tension wedge (11) moves to the edge of the slot (43) and is pressed down by the outer shell (4) as it continues to move. One end of the bent structure (132) in the locking tongue (13) is lifted up due to the lever action and abuts against the mounting plate. Step 6: The camera (22) acquires an image and detects that the latch (13) is raised, which proves that the hole alignment operation on the mounting plate has been completed. The tension wedge (11) is retracted, and the step ends.
