Technical Field
[0001] This utility model relates to the technical field of belt sanding devices, specifically a belt sanding device for welding seams for robots. Background Technology
[0002] Weld seam grinding is a processing method that uses abrasive belts as grinding tools to treat the surface of weld seams. In modern industrial production, weld seam grinding is a key step in metal processing and manufacturing, and its quality directly affects the structural strength, appearance quality, and service life of products. Traditional weld seam grinding methods, such as manual grinding or simple mechanical grinding, can meet basic requirements to a certain extent, but they have shortcomings and are difficult to adapt to the development trends of precision and environmental protection in modern industry.
[0003] Traditional manual grinding relies on human operation, which is not only labor-intensive but also slow, making it difficult to meet the needs of large-scale production. Furthermore, manual grinding is susceptible to factors such as operator skill level and fatigue, leading to inconsistent grinding quality. Weld grinding requires high precision, which traditional methods struggle to control, easily resulting in over- or under-grinding and affecting weld quality. Moreover, traditional grinding methods are inadequate for welds with complex shapes or in special locations. In addition, the welding grinding process generates a large amount of metal waste; if not collected and disposed of promptly, it will not only cause environmental pollution but may also pose a threat to the health of operators.

[0034] Furthermore, this embodiment incorporates an adjusting cylinder 424 connected to a connecting column and a moving block 425 to facilitate the adjustment of the position of the workpiece to be ground. Combined with a limiting plate 426 and a positioning rod 427, the workpiece can be stably placed on the supporting steel frame 422, facilitating grinding and collection operations. Simultaneously, a blower 4210 delivers air to an air blowing head 4213 via an air delivery telescopic pipe 4211 and a connecting pipe 4212. The airflow from the air blowing head 4213 rapidly blows the waste generated during the grinding process into the collection pool 421, achieving automatic waste collection.
[0035] In use, the device mainly consists of a support base 1, a controller 2, a mounting base 3, a rotating base 31, a protective shell 11, and a belt abrasion collection assembly 4. The belt abrasion collection assembly 4 is further subdivided into a belt abrasion section 41 and an air blowing collection section 42, which work together to complete the abrasion and waste collection tasks.
[0036] First, the robotic arm body 411 is fixedly mounted on the rotating base 31. The rotating base 31 can drive the robotic arm body 411 to rotate, thereby adjusting the grinding angle to adapt to the grinding requirements of different weld seams. The grinding mechanism mounting base 412 is fixedly mounted on the mounting end of the robotic arm body 411, providing a mounting base for the triangular support frame 413. The triangular support frame 413 is fixed to the grinding mechanism mounting base 412 by fixing bolts, providing stable support for components such as the servo motor 414.

[0037] Rotary wheel 417 and rotary wheel 418 are connected by a synchronous belt 419 to form a transmission system. When the servo motor 414 rotates, it drives rotary wheel 418 to rotate synchronously through the transmission system. Three sets of mounting limit wheels 4110 are installed on the inner wall of rotary wheel 418 via a connecting rotating shaft, located at the triangular mounting points of the triangular support frame 413. The grinding belt 4111 is connected to the outer wall of the mounting limit wheels 4110. When rotary wheel 418 rotates, it drives the grinding belt 4111 to move, thus grinding the weld seam.
[0038] Furthermore, a collection pool 421 is located on top of the support base 1, between the protective shells 11, and is used to collect waste generated during the grinding process. A supporting steel frame 422 is fixedly installed on the inner wall of the collection pool 421, and its top is provided with evenly spaced sliding holes 423 to support the workpiece to be ground and allow waste to pass through. An adjusting cylinder 424 is fixedly installed on top of the supporting steel frame 422, and its connecting end is connected to the moving block 425 via a connecting column.

A limiting plate 426 is fixedly installed on the top of the moving block 425, and positioning rods 427 are evenly spaced on the top of the limiting plate 426 to fix the position of the workpiece to be ground.
[0039] Furthermore, the blower 4210 is located on the outside of the support base 1, and its connection port is connected to an air supply expansion pipe 4211. The other end of the air supply expansion pipe 4211 is connected to a connecting pipe 4212, which is placed inside the pipe mounting groove 429 of the triangular mounting plate 428. Air blowing heads 4213 are evenly spaced and connected to the outer wall of the connecting pipe 4212, extending below the triangular mounting plate 428 and positioned diagonally above the supporting steel frame 422. When the blower 4210 operates, air is delivered to the air blowing heads 4213 through the air supply expansion pipe 4211 and the connecting pipe 4212. The airflow from the air blowing heads 4213 blows the waste generated during the grinding process into the collection pool 421, thus collecting the waste.
[0040] Workflow: The workpiece to be ground is placed on the supporting steel frame 422. The position of the workpiece is adjusted by adjusting the cylinder 424 and the moving block 425 to ensure the contact accuracy between the workpiece and the grinding belt 4111. Next, the grinding process: The servo motor 414 is started, driving the grinding belt 4111 through the transmission system to grind the weld seam. Simultaneously, the blower 4210 is started, blowing the waste generated during the grinding process into the collection tank 421 through the air blowing system. Post-grinding treatment: After grinding is completed, the servo motor 414 and blower 4210 are turned off, the ground workpiece is removed, and the waste in the collection tank 421 is cleaned.
