Description

Technical Field

[0001] This utility model relates to the field of power transmission tower processing technology, and in particular to an automatic positioning and locking robot for tower section connecting plates. Background Technology

[0002] In the fabrication of power transmission towers, the assembly accuracy of the tower section connecting plates directly affects the structural strength. Traditional methods rely on manual operation, which is inefficient and cannot meet the needs of large-scale production. Some production lines use robotic arms to replace manual labor, such as screw-tightening equipment. However, when changing tightening modules to accommodate different screw sizes, there are many steps involved, requiring workers to use tools. Space constraints further increase the operational difficulty, leading to longer equipment downtime and impacting overall production efficiency. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing technologies that require operators to use tools, where space constraints further increase the difficulty of operation, and to propose an automatic positioning and locking robot for tower section connecting plates.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic positioning and locking robot for tower section connecting plates includes a mounting base and a robotic arm mounted on one side of the mounting base;

[0006] The tightening module is located on one side of the robotic arm;

[0007] The mounting mechanism is used to install and fix the robotic arm and the tightening module. The mounting mechanism includes a fixed base fixedly disposed on one side of the robotic arm and an insert plate installed on one side of the mounting plate in the tightening module. The top and side wall of the fixed base are provided with the same slot. The insert plate is inserted into the inside of the slot. A rotating shaft is rotatably mounted on one side of the top of the fixed base. A flat abutment plate for abutting the insert plate is fixedly disposed on the outer wall of the rotating shaft.

[0008] The rotating shaft causes the flat plate to press against the insert plate, providing vertical constraint and achieving the initial positioning of the tightening module.

[0009] In one possible design, the mounting mechanism further includes two sliding semi-rings, and slide rails are provided at both ends on the other side of the top of the fixed base. The two sliding semi-rings are slidably connected to the outer walls of the two slide rails respectively.

[0010] In one possible design, the mounting mechanism further includes a fixed half-ring and a threaded cylinder. The fixed half-ring is fixedly mounted on the top of the side wall of the fixed seat. Two sliding half-rings close with the fixed half-ring to form a complete threaded ring. The threaded cylinder engages with the external thread of the rotating shaft through an internal thread. A threaded cavity is provided on one side of the threaded cylinder, and the threaded cylinder is threaded onto the outer wall of the threaded ring through the threaded cavity.

[0011] In one possible design, the outer wall of the threaded cylinder is provided with anti-slip texture so that the threaded cylinder can be manually rotated to complete the assembly and disassembly.

[0012] In one possible design, a limit block is fixedly provided at one end of the rotating shaft to limit the range of movement of the threaded cylinder.

[0013] In one possible design, the insert plate is a T-shaped steel component, and the slot is a T-shaped groove.

[0014] In this application, during actual use, the initial assembly of the tightening module is completed by inserting the insert plate on the side wall of the tightening module into the slot. Then, the shaft is rotated downward so that the flat plate on its outer wall abuts against the top of the insert plate, limiting the insert plate. Then, the two sliding half-rings can be moved inward to lock the shaft, and the two sliding half-rings and the fixed half-ring will form a complete threaded ring. Then, the threaded cylinder can be rotated to move and be threaded onto the outer wall of the threaded ring to achieve fixation, thereby achieving the assembly and fixation of the tightening module.

[0015] In this utility model, the automatic positioning and locking manipulator for tower section connecting plates provides vertical constraint through a flat abutment plate and forms axial locking between the threaded cylinder and the threaded ring, which can achieve stable installation of the tightening module and enable rapid disassembly and assembly, thereby reducing the downtime required for replacement.

[0016] In this utility model, the automatic positioning and locking manipulator for tower section connecting plates adopts a purely mechanical structure of sliding half-ring and threaded cylinder, which allows operators to complete disassembly and assembly without special tools, thus reducing maintenance costs.

[0017] In this invention, a flat abutment plate is used to provide vertical constraint during use, and an axial locking mechanism is formed by a threaded cylinder and a threaded ring to achieve stable installation and quick disassembly of the tightening module. By simplifying the operation process and reducing maintenance costs, the downtime required to replace the tightening module is shortened. Attached Figure Description

[0025] Mounting base 1 is fixed to the base of the power tower processing platform by bolts. The end of robotic arm 2 is connected to tightening module 3. Both are screw-locking robotic arms from Dongguan Jingxin Technology. Through the equipped vision system and intelligent capture, they can identify and position the tower section connecting plate, and at the same time cooperate with the tightening module to realize the screw-locking operation.

[0026] refer to Figure 2-3 The installation mechanism includes an insert plate 4 fixed to the side wall of the mounting plate in the tightening module 3. The insert plate 4 is a T-shaped steel component. The installation mechanism also consists of a fixed seat 8, a rotating shaft 6, a flat abutment plate 5, a sliding half-ring 12, a fixed half-ring 11, and a threaded cylinder 9. The fixed seat 8 is welded to the side wall of the robotic arm 2, and its top and side walls have T-shaped slots 7 for inserting the insert plate 4.

[0027] The rotating shaft 6 is mounted on the top of the fixed base 8 by rotation, and its surface is provided with a flat abutment 5 for pressing the insert plate 4 and limiting its position.

[0028] The mounting mechanism also includes two sets of sliding half-rings 12. Each set of sliding half-rings 12 is connected to the slide rail 10 via a linear bearing. The slide rail 10 is also a steel guide rail with a T-shaped cross-section. The fixed half-ring 11 is welded to the side wall of the fixed seat 8. Its inner diameter is the same as the inner diameter of the sliding half-ring 12 in the closed state, together forming a complete threaded ring.

[0029] The threaded cylinder 9 is threaded onto the outer wall of the rotating shaft 6, and a threaded cavity 13 is provided at one end, so that when the threaded cylinder 9 rotates, it is threaded onto the outer wall of the threaded ring through the threaded cavity 13, thereby achieving installation and fixation.

[0030] Specifically, the initial assembly of the tightening module 3 is completed by inserting the insert plate 4 on the side wall of the tightening module 3 into the slot 7. Then, the rotating shaft 6 is rotated downward so that the flat abutment plate 5 on its outer wall abuts against the top of the insert plate 4, limiting the insertion plate 4. Then, the two sliding half rings 12 can be moved inward to lock the rotating shaft 6. The two sliding half rings 12 and the fixed half ring 11 will form a complete threaded ring. Then, the threaded cylinder 9 can be rotated to move and be threaded onto the outer wall of the threaded ring to achieve fixation, thereby achieving the assembly and fixation of the tightening module 3.

[0031] This application can be used in the field of power transmission tower manufacturing, or in other fields applicable to this application.

[0032] In another embodiment: Reference Figure 4 An automatic positioning and locking robot for tower section connecting plates is applied to the field of power tower processing. The outer wall of the threaded cylinder 9 is provided with anti-slip texture 15 to facilitate manual rotation by the staff, and a limit block 14 is fixedly provided at one end of the rotating shaft 6 to limit the threaded cylinder 9.

[0033] However, as is well known to those skilled in the art, the working principles and wiring methods of the robotic arm 2 and the tightening module 3 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
