Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a self-cleaning centerless grinder. Background Art

[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding.

[0003] The existing centerless grinder sprays coolant on the surface of the workpiece during use to cool the workpiece during the grinding process. The coolant will flow out with the waste chips generated during the grinding process and will be filtered and recycled. During the filtration process, due to the use of gravity filtration, a large amount of coolant will still remain on the surface of the waste chips, requiring staff to manually clean them later, which not only wastes manpower and material resources, but also leads to poor use of the device. Therefore, a self-cleaning centerless grinder is urgently needed to solve the above problems. Utility Model Content

[0022] like Figure 1-Figure 4 As shown, a self-cleaning centerless grinder provided in this embodiment includes a box body 3, a guide seat 14 is fixed to the middle part of the top of the box body 3, a plurality of through holes are arranged in an array on the upper end of the guide seat 14, a bearing seat 8 is fixed to the middle part of the guide seat 14, a filter cartridge 15 is arranged below the guide seat 14, a limiting ring 16 is installed on the outer wall of the filter cartridge 15, a gear ring 17 is fixed to the upper end of the outer wall of the filter cartridge 15, a gear 18 is connected to one side of the gear ring 17, a servo motor 20 is fixed to the gear 18, a guide plate 19 is arranged on the outer side below the filter cartridge 15, a drain pipe 13 is arranged on one side of the guide plate 19, a valve 21 is fixed to the output end of the filter cartridge 15, a collecting frame 1 is arranged below the filter cartridge 15, and a blocking cover 2 is installed at the position of the box body 3 corresponding to the valve 21.

[0023] The guide seat 14 passes through the box body 3, and the top of the bearing seat 8 is an inclined structure. The guide seat 14 can discharge the coolant and waste chips, and the bearing seat 8 provides a placement position for the grinding parts.

[0024] One end of the limiting ring 16 is welded to the inner wall of the box body 3, and the filter cartridge 15 is rotatably connected to the limiting ring 16. The limiting ring 16 supports and limits the filter cartridge 15, and the filter cartridge 15 can separate waste chips from the coolant.

[0025] The ring gear 17 is welded to the outer wall of the filter cartridge 15, the gear 18 is meshed with the ring gear 17, and the output shaft of the servo motor 20 is fixedly connected to the gear 18. In the process of filtering the coolant and waste chips, the servo motor 20 drives the ring gear 17 to rotate through the gear 18, and then drives the filter cartridge 15 to rotate, so that the waste chips in the filter cartridge 15 are subjected to centrifugal force, and the coolant remaining on the surface thereof can be thrown out. On the one hand, the separation effect of the two is guaranteed, and on the other hand, there is no need for manual subsequent cleaning of the coolant on the surface of the waste chips, which saves manpower and material resources and effectively improves the use effect of the device.

[0026] The filter cartridge 15 is connected to the guide plate 19 through a bearing. The guide plate 19 is tilted. The drain pipe 13 is formed on the box body 3. The separated coolant is discharged through the guide plate 19 and the drain pipe 13 for collection.

[0027] The collecting frame 1 is slidably connected to the box body 3, the baffle 2 is connected to the box body 3 by a hinge, and the valve 21 is threadedly installed on the discharge end of the filter cartridge 15. When waste chips need to be collected, the baffle 2 is opened, and then the bottom end of the filter cartridge 15 is opened through the valve 21. At this time, the waste chips in the filter cartridge 15 fall into the collecting frame 1 for collection.

[0028] Supports 5 are welded at the four corners of the upper end of the box body 3, and a bidirectional screw 4 is installed between one group of supports 5. One end of the bidirectional screw 4 is connected to a driving motor 12, and a guide rod 10 is installed between the other group of supports 5. Two groups of bearing rods 11 are symmetrically sleeved on the bidirectional screw 4 and the guide rod 10. A frame 7 is fixed to the top of the bearing rod 11, and a grinding wheel 9 is rotatably installed in the frame 7. One end of the grinding wheel 9 is connected to a grinding motor 6. During the grinding process, the driving motor 12 drives the bidirectional screw 4 to rotate, and then the bearing rod 11 drives the two groups of grinding wheels 9 to move toward each other and contact the grinding piece under the action of the thread and the guide rod 10, and then the grinding motor 6 drives the two groups of grinding wheels 9 to rotate in opposite directions to grind the surface of the grinding piece.

[0029] The working principle of this device is as follows: connect the external power supply, place the grinding piece on the bearing seat 8, and then control the driving motor 12 to drive the bidirectional screw 4 to rotate, so that the bearing rod 11 drives the two sets of grinding wheels 9 to move towards each other and contact the grinding piece under the action of the thread and the guide rod 10, and then the grinding motor 6 drives the two sets of grinding wheels 9 to rotate in opposite directions to grind the surface of the grinding piece. During the grinding process, the external cooling mechanism will spray coolant on the surface of the grinding piece to cool the grinding piece. The coolant will carry waste chips through the through holes on the guide seat 14 and flow into the filter cartridge 15 for filtration. In the process of filtering the coolant and waste chips, the servo The servo motor 20 drives the gear ring 17 to rotate through the gear 18, and then drives the filter cartridge 15 to rotate, so that the waste chips in the filter cartridge 15 are subjected to centrifugal force, and the coolant remaining on the surface thereof can be thrown out. On the one hand, the separation effect of the two is guaranteed, and on the other hand, there is no need for manual subsequent cleaning of the coolant on the surface of the waste chips, which saves manpower and material resources and effectively improves the use effect of the device. The separated coolant is discharged through the guide plate 19 and the drain pipe 13 for collection. When the waste chips need to be collected, the baffle 2 is opened, and then the bottom end of the filter cartridge 15 is opened through the valve 21. At this time, the waste chips in the filter cartridge 15 fall into the collection frame 1 for collection.
