Description
Technical Field
The invention relates to a tool for cold welding, in particular to an electric spark surfacing repair machine.
Background
The electric spark deposition surfacing welding belongs to the category of cold welding, the discharge of micro-electric arcs is utilized to continuously deposit and bead weld materials on a welded workpiece product in the form of a micro molten pool, the heat input quantity in the welding process is low, the temperature rise of the workpiece product is small, the heat influence on the workpiece product cannot be achieved by the traditional arc welding, and particularly, the repairing effect on aluminum alloy is obvious.
The working mode of the existing electric spark overlaying welding gun is that a straight welding rod (welding material) is clamped on a chuck of the welding gun (the chuck is the chuck of a small electric drill), the chuck of the welding gun is driven by a small motor inside the welding gun to rotate at a high speed, and welding current is conducted to the chuck by a welding machine through a lead and an electric brush and is conducted to the welding rod through the chuck. The rotating welding rod and the pulsed welding current form high-frequency discharge between the welding rod and the workpiece to form micro arcs, and the micro arcs form micro molten pools to deposit the welding rod on a workpiece product in a micro melting point mode to form welding.
The welding machine is mainly used for cold welding repair, mold repair, casting defects and the like, and is manually held during working, so that the welding gun is not too large in size, inconvenient to hold due to large-size operation, incapable of welding in narrow gaps and small spaces, inflexible, and not too heavy in weight.
The current situation is that the motor of the electric spark overlaying welding gun is arranged at the inner rear end of the welding gun, the welding gun chuck is driven to rotate through the transmission shaft, the size of the welding gun is reduced for control, the motor is a motor with a small selected diameter, the general diameter is smaller than 40mm, the output torque force relative to the small motor is very small, but during welding, the motor drives the transmission shaft through the shaft coupling to drive the chuck arranged at the front end of the shaft to rotate, the annular carbon brush sleeve is pushed and pressed by the spring on the shaft to be tightly attached to the rear end face of the chuck, the carbon brush is tightly attached to the chuck in friction, great resistance is generated, and during welding, the welding rod and a workpiece discharge friction are generated, the generated resistance is generated during rotation of the connector between the transmission shaft and the motor, the output power of the motor is greatly consumed, and the rotating speed is reduced. Particularly, after the welding gun is used for a period of time, due to the fact that multiple parts are discharged, the friction surface is not smooth, or dust is involved in the welding gun, resistance is larger, the rotating speed is reduced, normal work cannot be achieved, the service life of the motor is seriously shortened, the motor needs to be frequently replaced twice a month, the problem is serious, which always troubles the performance and stability of the welding gun of the electric spark surfacing repair machine, and the industry is urgently needed to break through, so that the problems are solved.
Therefore, it is necessary to improve the existing welding gun, to solve the contradiction between the small welding gun volume and the large motor torque, and more importantly, to prolong the service life of the motor, reduce the frequency of replacing the motor, and reduce the welding gun volume, which is the power and starting point completed by this patent.
