Automatic cutting pick machining and welding device of coal mining machine

Abstract

The invention relates to the technical field of cutting picks, and discloses an automatic cutting pick machining and welding device of a coal mining machine. The automatic cutting pick machining and welding device comprises a shell, wherein a movable frame is slidably connected to the upper part of an inner cavity of the shell, telescopic columns are fixedly connected between the movable frame andthe top wall of the inner cavity of the shell, and symmetrical movable parts are slidably connected to the inner cavity of the movable frame; and connecting rods are movably connected between the movable parts and the side wall of the inner cavity of the shell, and symmetrical positioning toothed plates are slidably connected to the lower portion of the inner cavity of the shell. According to theautomatic cutting pick machining and welding device of the coal mining machine, the movable parts are driven by the movable frame to descend, the positioning toothed plates at the two sides are automatically folded to limit a welding part under the action of the connecting rods and push rods, and welding heads are driven by the rotating rod to automatically deflect to the welding part for welding, so that the welding part can be conveniently, stably and rapidly limited, the welding speed of the welding part is effectively improved, and the air health of a machining place is effectively guaranteed.

Description

Technical field [0001] The present invention relates to the field of truncation techniques, and is specifically a cutting machine of a coal-proof automatic processing welding device. Background technique [0002] The truncation is one of the lifting parts of the coal and the roadway. It is the main tool of the coal and crushed coal. Its performance is directly affected to the production capacity of coal mining machinery. The current cutting process The hard alloy truncing tip and the medium carbon alloy steel truncate body need to be welded together, and the general trunking welding device is not convenient for rapid and stable limits for the welds, and welded After being positioned, it is necessary to manually use the solder gun to weld the connecting portion. The operation process will result in slower welding speed, low processing rate, and the solder smoking generated during welding is generally unreaches directly to the processing place. In space, when the amount of welding ...

[0002] The pick is one of the vulnerable parts in coal mining and roadway excavation machinery. It is the main tool for falling coal and crushing coal. Its performance directly affects the production capacity of coal mining machinery. At present, the pick is in the process of processing It is necessary to weld the hard alloy pick tip and the medium carbon alloy steel pick body together, but the general pick processing and welding device is not convenient to quickly and stably limit the welded parts during use, and the welded parts After being positioned, it is necessary to manually use a welding torch to weld the connection part. The slow operation process will lead to slow welding speed and low processing speed. In addition, the welding smoke generated during welding will generally escape directly to the processing site without treatment. In the space, when the processing volume of welding parts is large, the amount of welding fume inside the processing site will continue to rise, which will damage the air quality and affect the physical and mental health of users

[0003] Aiming at the deficiencies of the prior art, the present invention provides an automatic pick processing and welding device for a shearer, which is capable of conveniently and automatically performing stable and fast position limitation on welded parts, effectively improving the welding speed of welded parts, and effectively It has the advantages of ensuring the air health in the processing place, and solves the problem that the pick processing and welding device of the general coal shearer is inconvenient to quickly and stably limit the welding parts, the welding speed is slow, and the welding in the processing place is not convenient. The problem that smoking is likely to have a bad impact on the user's physical and mental health
