Description

Technical Field

[0001] The invention relates to the field of special-shaped parts processing, and more specifically to a grinding device for processing special-shaped parts. Background Art

[0002] Special-shaped parts generally refer to parts that are complex and non-standard in shape, size or structure. These parts are different from conventional shapes (such as round, square or regular geometric shapes) in the manufacturing industry and often have special contours, irregular shapes or variable cross-sections.

[0003] In order to facilitate the grinding of special-shaped parts, the prior art (Chinese invention patent application with publication number CN115673939A) discloses a special-shaped automobile parts precision grinding system, which drives the grinding wheel and the grinding drill to perform circular motion through an arc frame, and then cooperates with the rotation of the worm ring and the worm groove on the mounting table to achieve all-round and multi-angle grinding of the parts; Although the equipment uses grinding drills and grinding wheels to achieve grinding processing of special-shaped parts, grinding drills and grinding wheels are usually suitable for fine grinding or small-area processing, and the grinding drills and grinding wheels need to be manually controlled during the grinding process to perform targeted grinding on special-shaped parts. When large-area special-shaped parts need to be processed, the grinding processing speed is slow, resulting in a long production cycle and low efficiency. At the same time, because grinding drills and grinding wheels are suitable for relatively fine grinding, they have poor adaptability when processing large-area special-shaped parts, especially for parts with complex shapes or large shape changes, and the entire surface may not be processed evenly.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This scheme is equipped with a side grinding unit, a concave-convex grinding unit and an end grinding assembly. The side grinding unit can realize large-area rapid grinding of special-shaped parts. The vertical layout of the grinding roller enables it to contact various shapes such as the side and curved surface of the workpiece, which helps to quickly remove the surface roughness layer and burrs. The concave-convex grinding unit can perform small-area targeted grinding of special-shaped parts, which is particularly suitable for processing edges, corners and delicate parts. The end grinding assembly can then realize grinding of the upper and lower ends of special-shaped parts, and can achieve all-round coverage grinding of special-shaped parts. It can better adapt to the overall contour of the parts, reduce the risk of local over-grinding or unevenness, and provide higher production efficiency while ensuring surface grinding uniformity.

[0017] (2) The present scheme is provided with an angle adjustment part 1 and an angle adjustment part 2. The angle of the special-shaped parts can be adjusted by the angle adjustment part 1 so that each surface of the special-shaped parts can be evenly ground, thereby avoiding the situation where some parts are over- or under-ground due to fixed angles. In particular, when processing parts with irregular or complex shapes, the contact mode between the part and the grinding tool can be adjusted in real time according to the curvature or angle of the part surface, so that the grinding effect is more uniform and fine. The angle of the grinding component can be adjusted by the angle adjustment part 2, thereby changing the contact angle between the sanding belt and the surface of the special-shaped parts. By adjusting the angle of the sanding belt, the shape of specific parts on the surface of the parts can be better adapted, especially for curved surfaces, edges, and uneven areas, ensuring that the sanding belt contacts the surface more accurately. For some areas that are difficult to grind directly, such as concave parts or chamfered parts, adjusting the angle of the sanding belt can better adapt to these complex geometric shapes, thereby achieving finer grinding.

[0018] (3) This scheme is provided with a uniform grinding drive component, which drives the abrasive belt to realize reciprocating motion through the uniform grinding drive component, so that the abrasive belt can realize more uniform grinding on the surface of the component. Especially when processing special-shaped components with complex or irregular shapes, the reciprocating motion can effectively prevent the abrasive belt from staying in a fixed area for too long, thereby preventing uneven grinding or local excessive wear on the surface. When the abrasive belt makes reciprocating motion, the heat can be dispersed over a larger area and is not easy to accumulate in a certain position, thereby avoiding the surface degradation of the part caused by overheating. It is particularly suitable for high-temperature sensitive materials, avoiding excessive accumulation of local heat, thereby reducing material deformation or surface damage caused by overheating, and can also increase the number of contacts between the abrasive belt and the workpiece. Compared with single rotation or fixed angle grinding, reciprocating motion provides a higher frequency of grinding contact, which can remove surface material more quickly and improve grinding efficiency.

The motor 24 drives the grinding roller 22 to rotate to quickly grind the special-shaped parts over a large area. The vertical layout of the grinding roller 22 enables it to contact with various shapes such as the side and curved surface of the workpiece, which helps to quickly remove the rough surface layer and burrs. The mobile end of the axial moving component 241 (an axial moving component composed of a motor, a screw rod and a screw sleeve, which belongs to the commonly used prior art and will not be described in detail here) moves with The two side plates 42, the seat body 46 and the movable seat 47 are moved, and the grinding assembly 48 performs small-area targeted grinding on special-shaped parts, which is particularly suitable for processing edges, corners and delicate parts.

[0034] By adopting the above technical solution, the cylinder 91 can push the push plate 92 and the mounting plate 94 to move in the direction of the sand belt 487, so that the bristles 97 can contact the sand belt 487. At the same time, the motor 96 can drive the hollow tube 95 and the bristles 97 to rotate, and the bristles 97 can clean the impurities on the surface of the sand belt 487. The rotation of the bristles 97 helps to brush away the accumulated dust from the surface of the sand belt 487. When the sand belt 487 runs at a high speed, the bristles 97 can continuously remove surface impurities during work to prevent abrasive clogging. This not only helps to keep the sand belt 487 clean, but also helps to reduce the damage caused by abrasion. The air jet can effectively blow away the tiny particles or dust embedded in the abrasive holes on the surface of the sand belt 487, especially for those tiny particles that are difficult to reach by the bristles 97. The air flow can quickly blow them away, and the air flow can quickly take these particles away from the surface to avoid the re-attachment of impurities. The bristles 97 are responsible for removing larger or tighter particles, and the air flow can immediately take them away or blow them away, reducing the time waste during the cleaning process.

[0035] like Fig. 9 As shown, the mounting plate 94 is also connected to a flexible debris cleaning component 10, and the flexible debris cleaning component 10 includes a movable groove 101 provided inside the mounting plate 94, a slide seat 102 slidably connected to the movable groove 101, an inclined groove 104 provided inside the slide seat 102, a slide plate 105 slidably connected to the movable groove 101, an inclined top block 107 fixedly connected to one side of the slide plate 105 and extending into the inclined groove 104, a cleaning rubber 103 fixedly connected to one side of the slide seat 102, and a screw rod 106 rotatably connected to the mounting plate 94, and the lower end of the screw rod 106 is rotatably connected to the upper end of the slide plate 105.

[0036] By adopting the above technical solution, when the cylinder 91 is extended to push the push plate 92 and the mounting plate 94 to move in the direction of the sand belt 487, the cleaning rubber 103 can also contact the surface of the sand belt 487. After the bristles 97 clean the sand belt 487, the remaining fine dust and micro particles can be further cleaned by the flexible friction of the cleaning rubber 103, ensuring that the abrasive pores of the sand belt 487 are thoroughly cleaned. At the same time, the impurities are first removed by the bristles 97 and then cleaned with the rubber, which can significantly reduce the wear of the rubber block. To extend its service life, the slide plate 105 can be driven to move downward by rotating the screw rod 3 106, and the slide plate 105 moves downward to drive the inclined top block 107 to move. The inclined top block 107 moves and contacts with the inclined groove 104 to push the slide seat 2 102 to the outside of the mounting plate 94. When one side of the cleaning rubber 103 contacts and wears the surface of the sanding belt 487, the cleaning rubber 103 can be brought into contact with the surface of the sanding belt 487 by pushing the mounting plate 94, thereby ensuring that the cleaning rubber 103 can clean the surface of the sanding belt 487.

For rapid grinding of a large area, the moving end of the axial moving component 2 41 is controlled to move to drive the two side plates 2 42 and the seat body 46 and the movable seat 47 located between the two side plates 2 42 to move. The grinding component 48 performs targeted grinding of special-shaped parts in a small area. The motor 6 56 drives the connecting piece 55 and the seat body 3 57 to rotate, and the contact angle between the grinding wheel 59 and the upper end of the part is adjusted. The motor 7 58 can drive the grinding wheel 59 to rotate, thereby grinding the upper end of the special-shaped part. After grinding, the upper end and the lower end of the special-shaped part are swapped to achieve grinding of the other end, thereby achieving all-round coverage grinding of the special-shaped parts.
