Description

Technical Field

[0001] The invention relates to the technical field of grinding, and in particular to a large-scale equipment for deburring, chamfering, polishing and surface grinding. Background Art

[0002] After the initial processing, the edge of the plate or flat mechanical parts not only has burrs, but the outer edge of the part needs to be chamfered and rounded before overall polishing. In particular, the cutting edges of the plates that are cut by laser cutting, gas cutting, and stamping will produce cutting edges, welding slag, burrs and other excess attachments that need to be removed by grinding before polishing, and grinding is difficult. Among them, the operator first needs to use a grinder to manually grind and remove burrs, and then use the grinder to grind and chamfer the outer edge of the plate or flat mechanical parts. However, the chamfering process is extremely time-consuming and labor-intensive. The different proficiency and techniques of each worker result in inconsistent chamfering positions and inaccurate control of the chamfering angle, which causes errors in mechanical parts and is not beautiful. After the manual chamfering is completed, the surface needs to be polished by a grinder.

The manual grinding method can no longer complete the processing of large chamfers efficiently and with high quality, so it needs to be improved. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1 and Figure 2 As shown, the present invention discloses a large-scale deburring, chamfering, polishing and plane grinding equipment, which includes a conveyor belt assembly 10, a frame 20, a deburring, chamfering, polishing and grinding device 30 and at least one set of plane grinding devices 40. The conveyor belt assembly 10 is used to convey the workpiece, wherein the conveyor belt assembly 10 includes a roller in the same plane and a conveyor belt tensioned on the roller, and the workpiece is placed on the surface of the conveyor belt facing upward, so that the surface to be processed of the workpiece faces the deburring, chamfering, polishing and grinding device 30 and at least one set of plane grinding devices 40.

[0038] The frame 20 is a rigid frame structure, which spans over the conveyor belt assembly 10. The deburring, chamfering, polishing and grinding device 30 and at least one set of surface grinding devices 40 are installed on the frame 20 and protrude and extend toward the conveyor belt assembly 10 to grind the workpiece located on the conveyor belt assembly 10. The frame 20 includes a support frame 21 located on both sides of the conveyor belt assembly 10 and a rigid beam 22 connected to the support frame 21.

The deburring, chamfering, polishing and grinding device 30 and at least one set of surface grinding devices 40 are installed on the rigid beam 22, which is convenient for installation and adjustment.

[0039] The deburring, chamfering, polishing and grinding device 30 is movably mounted on the frame 20, and the sliding direction of the deburring, chamfering, polishing and grinding device 30 is obliquely intersected with the conveying direction of the conveyor belt assembly 10.

The deburring, chamfering, polishing and grinding device 30 slides along the frame 20 to move away from or approach the conveyor belt assembly 10, so that the deburring, chamfering, polishing and grinding device 30 polishes the workpiece when it is close to the conveyor belt assembly 10. Among them, the plane grinding wheel 35 can grind the edge and surface of the workpiece.

[0040] When the grinding surface of the plane grinding wheel 35 is parallel to the surface to be processed of the workpiece, the plane grinding wheel 35 grinds the surface of the workpiece.

Optionally, the workpiece is set as a plate-shaped plate, wherein the plate can be processed into a preset shape by laser cutting, gas cutting, etc., and accordingly, welding slag and burrs are formed on the edge of the plate. The deburring, chamfering, polishing and grinding device 30 grinds burrs, welding slag and sharp edges formed by cutting of the plate by adjusting the angle of the grinding surface and the grinding direction, and the grinding effect is good.

The sliding direction of the plane grinding device 40 is obliquely intersected with the conveying direction of the conveyor belt assembly 10, and the plane grinding device 40 includes a grinding wheel 45 that rolls relative to the workpiece.

[0042] The plane grinding device 40 slides along the frame 20 to move away from or approach the conveyor belt assembly 10, so that the plane grinding device 40 grinds the workpiece when it is close to the conveyor belt assembly 10. The grinding wheel 45 can grind the surface of the workpiece. When the grinding wheel 45 rotates, the grinding wheel 45 grinds the surface of the workpiece. The plane grinding device 40 is used as a post-process of the deburring, chamfering and polishing device 30, and performs comprehensive grinding on the surface of the workpiece without dead angles to improve the grinding quality of the workpiece surface.

[0043] The deburring, chamfering, polishing and grinding device 30 and at least one group of plane grinding devices 40 move toward the conveyor belt assembly 10 and grind the workpiece. The workpiece moves with the conveyor belt assembly 10 so that the whole workpiece is continuously ground by the deburring, chamfering, polishing and grinding device 30 and at least one group of plane grinding devices 40, with a wide grinding range and good stability. The deburring, chamfering, polishing and grinding device 30 is a plane grinding wheel 35, and is located in the output direction of the conveyor belt assembly 10, grinding the burrs on the edge of the workpiece and the upward surface. At least one group of plane grinding devices 40 finely grinds the surface of the workpiece in turn, and the grinding effect is good. Among them, the "upper" and "lower" directions appearing in this application are the orientations of the surface equipment when it is installed on the ground, and the "front" and "backward" directions appearing in this application are the orientations of the surface conveying direction.

The first lifting assembly 32 is used to drive the first grinding support 36 and the grinding assembly 33 to move as a whole, so that the plane grinding wheel 35 can approach or move away from the conveyor belt assembly 10, thereby grinding the workpiece conveyed by the conveyor belt assembly 10.

[0046] The grinding assembly 33 is provided with a rotating plane grinding wheel 35, and each plane grinding wheel 35 can rotate under the drive of the grinding assembly 33 to grind the surface of the workpiece. The grinding assemblies 33 are distributed at intervals on the first grinding bracket 36 to form multiple continuous grinding planes.

Optionally, the grinding assemblies 33 are distributed in two or more rows along the first grinding bracket 36, and the rotation axes of the plane grinding wheels 35 installed in each row of the grinding assemblies 33 are in the same plane. Among them, the plane where each row of grinding assemblies 33 is located intersects the conveying direction of the conveyor belt vertically or obliquely to expand the grinding range of the grinding assembly 33 on the workpiece. Arranging multiple rows of grinding assemblies 33 can achieve non-dead angle grinding of large-area plates, with a wide grinding range and good effect. Furthermore, the adjacent two rows of grinding assemblies 33 are staggered to form a complementary grinding effect, thereby improving the stability and comprehensiveness of the workpiece grinding quality. Optionally, the grinding assembly 33 includes a grinding motor installed on the first grinding bracket 36 and a grinding connector installed on the output end of the grinding motor, and the plane grinding wheel 35 is installed on the grinding connector.

Optionally, the driving assembly includes a driving belt 342, a tensioning pulley 343 installed on the first grinding bracket 36, and an assembly motor 341 that drives and connects the driving belt 342, and two or more grinding components 33 are driven and connected through the driving belt 342 to achieve synchronous movement. The assembly motor 341 drives the driving belt 342 to rotate, so that the driving belt 342 drives the grinding component 33 to rotate. The tensioning pulley 343 is used to adjust the driving tension between the driving belt 342 and the grinding component 33, and the linkage effect is good.

[0048] In order to adapt to plates of different thicknesses and shapes and to adjust the mutual grinding pressure between the plane grinding wheel 35 and the workpiece, the lifting direction of the first lifting assembly 32 is perpendicular to the conveying direction of the conveyor belt assembly 10.
