Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a grinding wheel of the abrasive type. Background Art

[0002] A grinding wheel, also known as a vitrified abrasive tool, is a vitrified abrasive tool in which ordinary abrasives are solidified into a certain shape (mostly circular with a through hole in the center) by a binder and have a certain strength. A grinding wheel generally consists of abrasives, a binder, and pores, and these three parts are often referred to as the three elements of a vitrified abrasive tool; classified according to different binders, common ones are ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels; a grinding wheel is the most widely used and has the widest application surface among abrasive tools. During use, the grinding wheel is driven by equipment to rotate at a high speed, so that the grinding wheel can perform rough grinding, semi-finishing grinding, and finishing grinding, as well as grooving and cutting on the outer circular surface, inner circular surface, plane, and various profiled surfaces of metal or non-metal workpieces.

[0003] A grinding wheel of the abrasive type described in the utility model patent with the publication number CN220839475U includes a fixing plate. An adjusting and positioning mechanism is arranged on the top of the fixing plate, a grinding mechanism is arranged on the top of the adjusting and positioning mechanism, and a grinding wheel is arranged on the top of the grinding mechanism; the adjusting and positioning mechanism includes: fixing blocks, there are two fixing blocks, which are respectively fixedly connected to both sides of the top of the fixing plate, a sliding track is fixedly connected to the top of the fixing block, the tops of the two sliding tracks are connected to each other through a sliding connection plate, and two positioning holes are respectively opened on both sides of the top of the sliding connection plate. For this grinding wheel of the abrasive type, by setting the mutual cooperation of the sliding track and the sliding connection plate in the adjusting and positioning mechanism, the position of the grinding mechanism can be effectively adjusted, and the positioning bolt can be inserted into the positioning hole and the positioning groove, so as to fix the whole after adjustment.

For rough grinding and fine grinding, grinding wheels with different mesh numbers need to be disassembled and replaced. Moreover, when grinding, due to the narrow grinding wheel, the grinding range is small, and other grinding tools are needed for reprocessing, and equipment replacement or site transfer is required.

[0034] Embodiment 1:

[0035] As Figures 1 to 4 shown, this embodiment proposes a grinding wheel of the grinding type, including a base 1, a driving roller 2, a driven roller 3, a grinding assembly 4, a control assembly 5, a limiting mechanism 6, a placing groove 7, a slide block 8, a first support plate 9, a mounting block 10, and a second support plate 11 fixedly connected to the upper end of the mounting block 10 and on the same side as the first support plate 9.

[0036] Among them, a placing groove 7 is opened on the upper side of the base 1, a slide block 8 is arranged inside the placing groove 7, and the slide block 8 can slide back and forth inside the placing groove 7. A reciprocating lead screw 501 is arranged inside the placing groove 7, and the reciprocating lead screw 501 penetrates through the front and back of the slide block 8. By rotating the reciprocating lead screw 501, the slide block threadedly connected thereto is controlled to move back and forth. Limiting grooves 602 are opened on both sides of the slide block 8, and limiting guide rails 601 are fixedly connected to both sides inside the placing groove 7. The slide block 8 is limited by the limiting guide rails 601 being stuck inside the limiting grooves 602, so that the slide block 8 can only slide back and forth. The reciprocating lead screw 501 is controlled to rotate by a servo motor 502 fixedly connected to the front end of the outside of the base 1.

[0037] A mounting block 10 is fixedly connected to the upper rear side of the base 1. A second support plate 11 is fixedly connected to one side of the upper end of the mounting block 10. A first support plate 9 is fixedly connected to the same side of the upper end of the slider 8. A driven roller 3 is rotatably connected to one side of the first support plate 9 close to the slider 8. A synchronous rotating shaft 13 is rotatably connected to both sides of the first support plate 9. Both synchronous rotating shafts 13 are fixedly connected to the rotating shaft of the driven roller 3. One extends outward from the side of the driven roller 3 away from the first support plate 9, and a high-mesh fine grinding wheel 402 is fixedly connected to the end of this synchronous rotating shaft 13 away from the first support plate 9 by screws. A low-mesh coarse grinding wheel 401 is fixedly connected to the end of the other synchronous rotating shaft 13 away from the first support plate 9 by screws. Coarse grinding and fine grinding are carried out with two grinding wheels of different mesh numbers.

[0038] A second support plate 11 is fixedly connected to the side of the upper end of the mounting block 10 on the same side as the first support plate 9. A driving roller 2 is rotatably connected to one side of the second support plate 11 close to the mounting block 10. The driving roller 2 is controlled to rotate by a driving motor 12 fixedly connected to the other side of the second support plate 11. A ring-shaped grinding belt 403 is sleeved outside to connect between the driving roller 2 and the driven roller 3 to achieve transmission. And the grinding belt 403 can move under the drive of the two rollers for grinding. The movement of the slider 8 is used to make the two rollers move away from each other to tighten the grinding belt, or move closer to each other to facilitate the replacement of the grinding belt.

[0039] The combination of the low-mesh coarse grinding wheel 401, the high-mesh fine grinding wheel 402 and the grinding belt 403 is used to achieve different grinding degrees and grinding methods for different grinding parts, without frequently replacing the grinding tools, and the workpieces that can be ground are more diversified.
