Description

Technical Field

[0001] The invention relates to the technical field of plasma spraying, in particular to a plasma gun automatic spraying device. Background Art

[0002] With the increasing demand for high-performance materials in the industrial manufacturing field, surface treatment technology plays a key role in improving the service life, wear resistance and corrosion resistance of materials. Traditional spraying methods are inefficient and have unstable quality, making it difficult to meet the growing market demand.

[0003] At present, there are some plasma spraying equipment on the market, mainly including manual plasma spraying equipment, semi-automatic plasma spraying equipment and fully automatic plasma spraying equipment. Among them, manual plasma spraying equipment manually adjusts the spraying angle, distance and spraying path to treat the workpiece surface. It is suitable for workpieces of various shapes and is often used in small batch production or processes that require flexible adjustment; semi-automatic plasma spraying equipment usually includes an automatically controlled spray gun position adjustment system and a manually operated workpiece clamping device. However, the above equipment has the following shortcomings in actual use:

[0004] On the one hand, in the existing plasma spraying technology, traditional manual equipment is completely dependent on manual operation, and operators need to frequently adjust and monitor, which increases labor intensity and operating difficulty, thereby reducing work efficiency. Operators need to spend a lot of time adjusting and moving the spray gun, making it difficult to achieve continuous and rapid spraying. Moreover, manual operation is easily affected by factors such as fatigue and emotions, and the speed will gradually slow down after working for a period of time, further reducing production efficiency.

[0005] On the other hand, the spraying quality is unstable. Different operators have different technical levels and operating habits, which makes it difficult to maintain consistent spraying thickness and uniformity. Even for the same operator, the operation at different times may fluctuate, affecting the stability of product quality.

[0006] In addition, manual operation is harmful to the health of operators. Plasma spraying generates high temperature, dust and harmful gases. Operators exposed to such an environment for a long time are prone to occupational health problems such as respiratory diseases and skin diseases. At the same time, manual operation is labor-intensive and can easily cause physical injuries such as muscle strain.

[0007] In summary, the research and development and improvement of the current plasma spraying equipment with complex spraying operation and unstable spraying quality has become a research and development direction that technical personnel in this field need to solve urgently. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a plasma gun automatic spraying device that can accurately control the spraying process without manual intervention, thereby improving production efficiency and consistency of spraying quality.
