Description

Grinder for surface burr treatment of sheet metal part Technical Field The invention belongs to the technical field of workpiece polishing, and particularly relates to a sheet metal part surface burr treatment grinder. Background In the current sheet metal part machining process, slag, flanging or sharp burrs are inevitably generated at the edges, the orifices and the cutting joints of the workpiece. Such burrs not only affect the appearance and assembly accuracy of the product, but may scratch operators and even interfere with subsequent spraying, welding or bending procedures, and must therefore be removed effectively. In order to improve the automatic deburring efficiency, various compound motion polishing devices have appeared in the prior art. For example, patent No. CN219666058U discloses a multi-grinding wheel deburring apparatus, which expands the polishing coverage to a certain extent by providing a plurality of grinding wheels and combining revolution and rotation motions, and is suitable for batch processing of symmetrical structures or regular hole systems. However, in practical application, all grinding wheels of the device are rigidly fixed below the grinding wheel frame, and the axial position, the mutual included angle and the mounting height of the grinding wheels are completely not adjustable. Although orbital motion may cause the wheel path to revolve around the workpiece a circle, achieving a spatially wide sweep, due to lack of attitude adaptation capability, "path-passing" is not equivalent to "effective grinding". On the one hand, when working with sheet metal parts with chamfer, bevel edge hole, concave steps or non-perpendicular cuts, the fixed vertically mounted grinding wheel is difficult to form an effective fit with the complex edge, often acts on the burr root only with point contact or local line contact, resulting in deviation of the grinding force direction from the optimal cutting path, a significant reduction in dehairing efficiency, and even inability to access the inside of the aperture or the transition area. On the other hand, the grinding wheels are generally arranged symmetrically around the center of the mounting plate, and only symmetrical structures (such as a central hole and uniformly distributed holes) distributed around the center of the workpiece can be covered efficiently. If the burr is located in the eccentric area (such as a single hole, an asymmetric notch or a special-shaped contour near one side edge), even if the revolution path passes through the area, the grinding wheel is often only scraped from the edge due to fixed radial position, the effective contact time is extremely short, the pressing depth is insufficient, the dehairing is incomplete, and local residues are formed. Such problems are particularly pronounced in dense shaped hole clusters or in custom small volume production. Disclosure of Invention In view of the foregoing, it is an object of the present invention to provide a sheet metal part surface burr treatment grinder, which solves the above-mentioned problems in the prior art. In order to solve the technical problems, the technical scheme of the invention is that the sheet metal part surface burr treatment grinder comprises a feeding belt and a treatment device, wherein the feeding belt is used for conveying a workpiece to be treated, the treatment device is positioned above the feeding belt and is used for deburring the workpiece on the feeding belt, the treatment device comprises a mounting plate, a surface treatment part is arranged on the mounting plate in a swinging manner and is provided with a driving part, the driving part starts the surface treatment part to perform deburring operation on the workpiece to be treated, and the surface treatment part swings on the mounting plate to adapt to surface contour fluctuation or edge height change of the workpiece. Preferably, the driving part comprises a control block, the control block is arranged on the mounting plate in a sliding way, the sliding path of the control block is arranged in an arc shape, the surface treatment part is arranged on the control block, and the surface treatment part is driven to swing relative to the mounting plate through the sliding of the control block along the arc path. The driving component comprises a driving bevel gear and a transmission bevel gear, the driving bevel gear is rotatably arranged on a mounting plate, the transmission bevel gear is rotatably arranged on a control block, the transmission bevel gear is in transmission connection with the surface treatment component, the sliding path of the control block is arranged in a circular arc shape by taking the rotation axis of the driving bevel gear as the center, the driving bevel gear and the transmission bevel gear are always meshed in the swinging process of the control block, and therefore power is continuously transmitted to the surface treatment component, and stable operation of the surfac
