Description

Technical Field

[0001] This invention belongs to the field of automotive painting technology, specifically relating to a flexible protective sleeve disassembly and assembly device for a painting robot's handshake. Background Technology

[0002] Existing commercial vehicle cab painting lines utilize robotic spraying. To prevent paint contamination of the robot's pipes and wiring during the spraying process, their routing is often internal. The handshake, as a flexible moving component of the painting robot, has multiple gear mechanisms internally. During movement, the internal pipes and wiring are highly susceptible to friction and interference with these gear mechanisms, leading to damage. Therefore, existing painting robots incorporate flexible protective sleeves within the handshake cavity to protect the pipes and wiring. Currently, these flexible protective sleeves are typically installed and removed manually without tools, which is not only inefficient but also poses a threat to employee occupational safety due to the lubricant and mechanical components inside the handshake.

[0003] During installation, the worker first holds the inner mounting interface of the flexible protective sleeve of the hand shaft and inserts it into the inner end of the hand shaft cavity. After the inner installation is completed, the outer interface is then tightened to the outer end of the hand shaft. The disassembly process is the reverse of the installation process: first, the fasteners on the outer end of the hand shaft are removed, and then the protective sleeve is pulled directly out of the hand shaft cavity. The hand shaft cavity is narrow, making it difficult to see inside, which is not easy to operate. Existing technology takes a long time each time, and it also has many gear mechanisms and is soaked in a large amount of lubricant, resulting in a harsh operating environment that is harmful to occupational health. Summary of the Invention

[0004] The purpose of this invention is to provide a flexible protective sleeve disassembly and assembly device for the hand shaft of a spraying robot, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A flexible protective sleeve disassembly and assembly device for a spraying robot handshake includes an upper connecting flange, a hand-tightening screw, a rotating boss, a connecting main board, a lower connecting flange, a connecting main rod, a tool head, a disc knob, a tool stroke adjusting screw, a conical top rod adjusting screw, a conical top rod, and a traction pin assembly.

[0007] The upper connecting flange and the connecting main plate are connected by screws. The rotating boss head is inserted into the middle hole of the upper connecting flange. The lower connecting flange and the connecting main plate are connected by screws. The connecting main rod is connected to the lower connecting flange and the tool head respectively. The traction pin assembly is set on the tool head, forming the main body of the device.

[0008] One end of the conical top rod adjusting screw is inserted into the tool stroke adjusting screw, and the other end is inserted into the conical top rod. The disc knob is connected to the other end of the tool stroke adjusting screw, forming the screw assembly part.

[0009] After inserting the lead screw assembly into the main body of the device via the rotating boss, the stroke of the lead screw assembly is adjusted by rotating the boss and using hexagonal bolts.

[0010] Furthermore, the inner cavity of the rotating boss is provided with an internal thread, and three threaded holes are evenly distributed on the side of the rotating boss. A hand-tightening screw is installed in each threaded hole, and each threaded hole communicates with the inner cavity of the rotating boss.

[0011] Furthermore, there are four spacer bolts on the outer periphery of the motherboard, and each spacer bolt has a star-shaped handle.

[0012] Furthermore, it also includes a T-shaped guide plate, which is connected to the side wall of the main board, and a guide pin is provided on the T-shaped guide plate.

[0013] Furthermore, the main connecting rod and the lower connecting flange are connected by a flat key.

[0014] Furthermore, the traction pin assembly includes a traction pin, a threaded hole on the side of the traction pin, a traction pin limiting screw installed in the threaded hole, a threaded hole pre-drilled on the side of the tool head for installing a spring limiting screw, and a compression spring installed between the traction pin limiting screw and the spring limiting screw.

[0015] The beneficial effects of this invention are:

[0016] The problem addressed by this invention is that existing methods for assembling and disassembling the flexible protective sleeve of the spraying robot's handshake are time-consuming, involve harsh operating environments, and pose occupational health hazards. It enables rapid assembly and disassembly of the flexible protective sleeve for the spraying robot's handshake, improving maintenance efficiency and preventing occupational health hazards to employees during maintenance.
