Description

TECHNICAL FIELD

[0002] The gear box body adopts welding type in the production process, which can improve the machining precision, compact structure and mechanical properties, but has the problem of difficult machining. The difficulty of machining mainly lies in the large amount of machining and the deformation caused by thermal expansion and cold contraction in the welding process.

[0003] The existing related patent, patent application number CN202311418202.3 "a gear box welding device", has the characteristics of "two groups of sliding rails are fixed on the vertical and horizontal welding plates, the joint seam is located between the two groups of sliding rails, the connecting plate and the fixing frame slide along the sliding rails forward and backward through the sliding block, the operator holds the operating rod, and pushes and pulls it towards the joint seam or away from it to control the distance between the end of the welding rod and the joint seam. The operating rod can drive the welding rod to move forward and backward along the joint seam. When the end of the welding rod contacts the joint seam, the welding core in the welding rod is melted to produce high temperature. The air pump pumps compressed gas into the blowing channel through the hose. After the compressed gas enters the chute, the air pressure in the chute increases. The airflow passes through each blowing hole and blows towards the joint seam. The airflow speed in the blowing hole closest to the sliding block is the largest. The airflow contacts the right side of the vertical welding plate and the upper surface of the horizontal welding plate during the blowing process and exchanges heat. The vertical welding plate and the horizontal welding plate near the welding point are cooled to reduce the thermal deformation effect and improve the welding precision. The sliding block can block the blowing holes above and to the right of the welding rod to avoid the airflow directly blowing towards the welding point, reduce the influence on the welding, and improve the welding quality." But it still has some shortcomings, such as in the welding process, the welding agent particles are easy to be stuck in the chute or other limiting structures, the limiting structure includes limiting column, the welding agent particles stuck in the limiting structure are easy to cause structure wear and damage, and the high temperature in the relative movement process may also cause the welding agent to melt and further damage the limiting structure, thus a gear box welding device is proposed.
