The workbench 2 is equipped with a synchronization component 5 at the top and a first motor 10 at the bottom. The synchronization component 5 includes a first rotating rod 504, a drive gear 505, a cylindrical cam 503, and a moving plate 509 in a limiting frame 502. The moving plate 509 is slidably connected to the reciprocating groove 507 of the cylindrical cam via a driven rod 506, which drives the cleaning blade 508 to reciprocate. The first motor 10 drives the first rotating rod 504 to rotate, and the cylindrical cam 503 pushes the driven rod 506 through the reciprocating groove 507, so that the moving plate 509 moves horizontally reciprocally within the limiting frame 502, and the cleaning blade 508 moves synchronously.

The concentric design of the limiting ring 24 and the limiting ring 21 ensures stability. The bidirectional lead screw structure ensures symmetrical clamping and prevents the workpiece from shaking during welding.
[0019] The inner wall of the connecting frame 7 is rotatably connected to the surface of the bidirectional lead screw 18; The cleaning knife 508 is made of cemented carbide, and its blade surface is coated with a wear-resistant coating. The wear-resistant coating is one of tungsten carbide, titanium nitride or diamond-like coating. The hardness of the cleaning knife 508 is not less than HRC60, and the blade thickness is 2-5mm. The tilt angle is 15°-30° to adapt to the surface cleaning needs of raw materials 8 of different materials. The bottom of the worktable 2 is fixedly connected to the support frame 1. The connecting frame 7 supports the bidirectional lead screw 18, and the cleaning blade 508 adopts a 15°-30° tilt angle design to adapt to various materials; The connecting frame 7 enhances the rigidity of the bidirectional lead screw 18 and reduces vibration. The tilted cutter head optimizes the cutting force, and the tungsten carbide coating is used to cope with high-hardness weld slag.
[0020] This metal component welding reinforcement device adopts a modular design, mainly including a workbench 2, a synchronization component 5, a welding system, a clamping mechanism, and a cleaning system, realizing the simultaneous operation of welding and slag removal. Its core functions are as follows: Synchronous welding and cleaning: Driven by a single motor, the welding head 26 and the cleaning blade 508 work together to clean the welding slag while welding, thus improving processing efficiency; Adaptive clamping: The bidirectional lead screw 18 drives the limit retaining ring 24 to adjust the clamping range, which is convenient for clamping metal parts after they are stacked. High wear-resistant cleaning: The 508 carbide cleaning blade, combined with a wear-resistant coating (tungsten carbide, titanium nitride, etc.), ensures long-term stable cleaning of high-hardness welding slag; In this invention, the first motor 10 drives the first rotating rod 504 to rotate via a coupling, which in turn drives the driving gear 505 and the cylindrical cam 503 to rotate synchronously. The reciprocating groove 507 of the cylindrical cam 503 cooperates with the driven rod 506 to convert the rotational motion into the horizontal reciprocating motion of the moving plate 509, so that the cleaning blade 508 continuously scrapes the surface of the workpiece. The driving gear 505 meshes with the driven gear 20, which drives the raw material 8 in the limiting ring 21 to rotate, thereby achieving uniform cleaning in the entire circumference.
[0021] This invention reduces energy consumption and space occupation by using a single motor to drive dual functions (rotating workpiece + cleaning). The reciprocating groove 507 design ensures stable stroke of the cleaning blade 508, avoiding missed cleaning or excessive wear. The welder 3 controls the height of the welding head 26 through the lifting device 25 to adapt to different welding thickness requirements. The control console 4 integrates current and speed adjustment functions to optimize welding parameters (such as penetration depth and uniformity of weld layer). This invention reduces the time wasted on welding and cleaning in traditional processes by performing welding and cleaning simultaneously. It is suitable for welding repair of various metals such as stainless steel and alloy steel. The second motor 11 drives the bidirectional lead screw 18, which causes the second L-shaped plates 22 on both sides to move the limiting rings 24 synchronously, clamping or releasing the limiting rings 21. The limiting rings 24 and 21 are concentrically arranged to ensure no radial runout when the workpiece rotates. The limiting plate 15 and the slide 14 cooperate to guide the workpiece and prevent welding vibration from causing it to shift. The cleaning blade 508 is made of cemented carbide with a hardness ≥ HRC60 and is coated with tungsten carbide / titanium nitride coating, which increases its life by more than 3 times. The blade thickness is 2-5mm and the tilt angle is 15°-30°, balancing cutting force and wear resistance, and is suitable for different materials (such as cast iron and high carbon steel). This invention improves efficiency by more than 30% compared to traditional step-by-step processes by performing welding and cleaning simultaneously. Real-time cleaning of weld slag avoids slag inclusion defects and enhances the bonding strength of the weld overlay. By adjusting the clamping mechanism, cleaning blade angle, and welding parameters, it can be extended to different industries (such as energy, shipbuilding, and heavy machinery). The modular design reduces manufacturing costs, and wear-resistant parts reduce long-term maintenance costs.
[0022] This invention has the following application scenarios: Shaft repair: weld overlay reinforcement of drive shafts in mining machinery and propulsion shafts in ships; Ring component machining: Surface repair of ring-shaped components such as gears and bearing housings; High-hardness surfacing: tungsten carbide surfacing and immediate cleaning of wear-resistant plates and rolls.
[0023] This invention simplifies the transmission structure by using a single motor to drive rotation, cleaning, and welding. The cylindrical cam-reciprocating groove mechanism achieves high-precision linear reciprocating motion, ensuring thorough cleaning. The symmetrical design of the bidirectional lead screw and limit circlip balances clamping speed and stability. The combination of carbide cutting tools and welding processes extends the life of key components. Through innovative mechanical structure and intelligent control, this device solves the pain points of low efficiency and slag affecting quality in traditional surfacing processes, making it suitable for the field of strengthening and repairing high-precision, high-strength metal parts.
