Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a rotary clamping mechanism for processing wear-resistant coatings by thermal spraying on metal surfaces. Background Technology

[0002] In the complex operating systems of modern industry, metal materials serve as fundamental building blocks. Whether it's the precision transmission components that operate at continuous high speeds in the machinery manufacturing industry, the internal components of engines that withstand enormous pressure and frequent friction in the automotive industry, or the key structural parts of aircraft facing extreme temperatures and airflow impacts in the aerospace field, metal components all bear core functions. Thermal spraying technology, as an advanced surface engineering technology, provides an effective solution for improving the wear resistance of metal materials. This technology uses a high-temperature heat source to heat the wear-resistant material to a molten state and sprays it onto the surface of the metal substrate at high speed, thereby forming a wear-resistant coating that is tightly bonded to the substrate. This coating not only significantly improves the wear resistance of metal components but also enhances their corrosion resistance and high-temperature resistance, greatly expanding the application range and service life of metal materials.

[0003] The rotary clamping mechanism for thermal spraying wear-resistant coatings on metal surfaces consists of a base, a rotating shaft, clamping components, a drive device, a positioning device, and a control system. It allows the workpiece to rotate at a uniform and stable speed, ensuring the spray gun maintains a suitable distance and angle with the workpiece surface at different positions. This ensures uniform wear-resistant coating thickness and improves the coating's wear resistance and protective performance. However, to fully utilize the advantages of thermal spraying technology, traditional fixing and simple rotation methods struggle to maintain a stable distance and angle between the spray gun and the workpiece surface during the thermal spraying process when dealing with metal workpieces of varying sizes. Existing technologies use laser rangefinders to monitor the distance and angle between the spray gun and the workpiece surface in real time to maintain a stable distance and angle. However, if workpieces of different sizes cannot be fixed during the thermal spraying process, only workpieces within a specific size range can be processed, leading to reduced actual equipment operating time and lower equipment utilization. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rotary clamping mechanism for processing wear-resistant coatings by thermal spraying on metal surfaces. It aims to improve the problem in the prior art that if workpieces of different sizes cannot be fixed during the thermal spraying process, only workpieces within a specific size range can be processed, resulting in reduced actual operating time and lower equipment utilization.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rotary clamping mechanism for processing wear-resistant coatings by thermal spraying on metal surfaces, comprising a support platform, a motor fixedly connected to the top left side of the support platform, a bevel gear fixedly connected to the output end of the motor, a bevel gear two meshing with the outer wall of the bevel gear one, a rotating shaft two fixedly connected to the middle of the bevel gear two, the right side of the rotating shaft two rotatably connected to the top left side of the support platform, a mounting plate fixedly connected to the left side of the rotating shaft two, and a support frame fixedly connected to the top of the mounting plate.
