When the external moving device for welding is moved, the welding push rod 372 is gradually extended so that the welding rod can continuously align with the guide rail. Welding action, the clamping branch chain 377 can clamp different types of welding torches, put the welding torches into the two clamping jaws 3773, and the arc surface of the inner side of the clamping support block 3774 can fit the outer side of the welding torch , control the two clamping jaws 3773 to clamp the welding torch, and the teeth on the inner side of the clamping jaws 3773 can increase the clamping effect of the welding torch. At this time, the clamping support block 3774 will automatically expand and contract under the action of the clamping spring 3775, so that Cooperate with the clamping jaws 3773 to securely fix different welding torches, and control the present invention to carry out welding actions. When the welding rod on the welding torch needs to be replaced, the fixing of the welding torch to the welding rod end will be released, and the welding rod end will follow the arc set on the clamping jaw 3773. The shaped guide block falls into the recovery frame 3777, and a new electrode is manually put into the welding torch. The recovery rod 3779 can flatten the end of the electrode in the recovery frame 3777, preventing the electrodes from accumulating in one place, and controlling the recovery push rod 3778 performs telescopic movement, the recovery rod 3779 can flatten the welding rod end of the recovery frame 3777, the cleaning and grinding mechanism 38 can clean up the welding slag at the bottom of the guide rail of the machine tool and the welding slag on the machine tools on both sides of the guide rail, and polish the electric slider 381 The height of the cleaning and grinding mechanism 38 can be adjusted, and the telescopic movement of the grinding push rod 382 can adjust the position of the grinding mechanism 38, so that the grinding inner plate 384 is in contact with the lower end outer surface of the machine tool guide rail. The scraper block provided on the bottom surface of the lower end of 383 is in contact with the top of the cleaning body and the machine tool. The movement of the motor slider 386 can adjust the position of the grinding disc 388, so that the grinding disc 388 moves to a suitable grinding position. When the external mobile device moves , control the grinding motor 385 to rotate, thereby driving the outer end to be an arc-shaped grinding disc 388 to polish the weld seam smoothly, and the scraping teeth of the grinding inner plate 384 can clean up the welding slag on the outer surface of the lower end of the machine tool guide rail. The grinding frame 383 is provided with The scraping block can clean up the welding slag on the top of the machine tool, and the cleaning body provided by the grinding frame 383 can clean up the welding slag scattered on both sides of the scraping block on the grinding frame 383, thereby eliminating the need for manual cleaning of welding slag and welding seam. It realizes the function of automatic welding and post-welding treatment of the guide rail of the EDM machine tool, and solves the problems that the welding slag will splash everywhere when the guide rail is welded and the welding angle of the guide rail is solved when the guide rail of the EDM machine tool is welded. Changes will lead to poor welding effect, the end of the electrode may stick to the machine tool when it is discarded, and the guide rail cannot be automatically processed after welding, etc., and the goal has been achieved.
