Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a robotic arm for all-around plasma spraying. Background Technology

[0002] Plasma spraying is a thermal spraying process that forms a coating on a material surface by heating particles to high temperatures and accelerating their spraying onto the substrate. This technology utilizes a high-energy heat source to melt fine particles and rapidly cool and solidify them, forming layered coatings. The main techniques of plasma spraying include flame spraying, plasma spraying, high-velocity oxygen fuel (HVOF) spraying, vacuum plasma spraying, arc metallization, and explosive gun spraying. Among these, flame spraying, HVOF spraying, and plasma spraying are particularly common in the preparation of bioactive bioceramic coatings. When applying composite coatings to mechanical parts (rollers, flat parts, contact surfaces, etc.), combined with advanced machining capabilities, various metal, ceramic, and polymer materials can be effectively combined, giving equipment parts unique functions such as anti-sticking, wear resistance, anti-slip, insulation, corrosion resistance, heat insulation, and self-lubrication, effectively improving component performance and lifespan. To ensure comprehensive coating of mechanical parts, a robotic arm for all-around plasma spraying is typically used.

[0003] In practical use, existing plasma omnidirectional spraying robots typically have the plasma spray gun fixed to the robot arm. When the plasma spray gun needs to be replaced or maintained, it is difficult to install and disassemble it quickly. In addition, the plasma spray gun needs to be connected to the plasma equipment and spraying equipment during use. The connection requires various pipes or wires. Most of these connections are placed directly on the ground. When the omnidirectional robot arm moves, the plasma spray gun will rub against the ground continuously, which can easily cause damage and does not improve the safety of spraying.

[0016] (III) Beneficial Effects

[0017] This utility model provides a robotic arm for omnidirectional plasma spraying, which has the following beneficial effects:

[0018] 1. This omnidirectional plasma spraying robot, through the setting of limiting components and quick-installation components, allows for the removal and disassembly of the plasma spray gun body when replacing or maintaining it. By turning the handwheel, the adjusting rod rotates, moving the adjusting block backward, thus removing the plasma spray gun body. During installation, the plasma spray gun body is inserted into the limiting component, and turning the handwheel rotates the adjusting rod, pushing the adjusting block to fix the plasma spray gun body in place. This achieves convenient and quick installation, avoiding the difficulty of quick installation and disassembly when the plasma spray gun is fixed on the robot arm and needs to be replaced or maintained, thereby helping to reduce the time cost of installation and disassembly.

This omnidirectional plasma spraying robot, through the setting of support columns, adjusting balls, limiting components, and limiting abutments, binds the external pipes or lines connected to the plasma spraying gun together during use, locking them in the limiting half ring and the limiting upper ring. Tightening the limiting bolt allows the limiting abutment to press against the surface of the external pipes or lines. If the limiting direction needs to be adjusted, the adjusting ball can be adjusted to change its orientation, thereby achieving the function of fixing the pipes and lines, avoiding the pipes or lines being placed directly on the ground, which would cause friction and damage, and helping to improve the safety of spraying.
