Description

Technical Field

[0001] The utility model relates to the technical field of bucket tooth grinding and polishing, in particular to a grinding tool suitable for the tip of an excavator bucket. Background Art

[0002] The tip of an excavator bucket is usually called the bucket tooth. During the excavation process, the bucket tooth is easily worn or deformed due to frequent contact with hard materials, affecting its cutting ability and operating efficiency. Using special grinding equipment (such as a grinding wheel machine) to grind the bucket tooth can quickly remove surface damage, repair the edge shape, and restore its sharpness and working performance.

[0003] Abrasive equipment (such as a grinding wheel machine) is a type of processing equipment that uses a motor to drive a grinding wheel to rotate at high speed and is used for grinding, dressing, and polishing metal and non-metallic materials. It is widely used in industrial manufacturing and maintenance fields.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3The utility model provides an embodiment: a grinding tool suitable for the tip of an excavator bucket, comprising a workbench 1, a grinding machine body 2 is mounted on the top of the workbench 1, a fixed frame 3 is provided on the top of the workbench 1, a clamping adjustment assembly 4 is mounted inside the fixed frame 3, a slider 5 is slidably connected inside the fixed frame 3, and a docking assembly 6 is mounted on the side of the slider 5; the clamping adjustment assembly 4 comprises a gear 7, the gear 7 is rotatably connected to the inside of the fixed frame 3, a rack plate 8 is slidably connected inside the fixed frame 3, the rack plate 8 and the gear 7 are meshed with each other, the rack plate 8 is fixedly connected to the side of the slider 5, and the gear 7 is controlled to rotate so that it controls the rack plate 8 to move together with the slider 5. A motor 9 is mounted on the rear side of the fixed frame 3, and the gear 7 is fixedly connected to the output end of the motor 9. The motor 9 rotates the gear 7 to drive the rack plate 8, the slider 5 and the docking assembly 6 to move together to clamp.

[0034] Reference Figure 1 、 Figure 4 and Figure 5 The docking assembly 6 includes a docking shell 10, which is fixedly connected to the side of the slider 5. A docking shell 2 11 is provided at one end of the docking shell 10, and a clamping plate 12 is fixedly connected to one end of the docking shell 2 11. The interiors of the docking shells 10 and 11 are both fixedly connected with docking blocks 13. The interior of the docking block 13 is rotatably connected with a rotating block 14. The docking block 13 of the docking shell 2 11 enters the interior of the docking shell 10 and squeezes the rotating block 14 to rotate it counterclockwise. The rotating block 14 is rotatably connected with a spring telescopic rod 15. One end of the spring telescopic rod 15 is rotatably connected to the inner side of the docking shell 10. The tension applied by the spring telescopic rod 15 causes the rotating block 14 to rotate clockwise. The docking block 13 has a slot 16 defined within it, and the rotating block 14 pivots and connects within this slot, connecting the two docking blocks 13. When the slot 16 forms a complete circle with the docking block 13, the rotating block 14, under the tension of the spring-loaded telescopic rod 15, rotates and engages the docking block 13, completing the installation of the correspondingly shaped clamping plate 12. Both docking shells 10 and 11 have limit slots 17 defined on their sides. One end of the rotating block 14 slides within this slot, limiting the rotational position of the rotating block 14.

[0035] Reference Figure 1 、 Figure 2 and Figure 4 Buffer pads 18 are installed on the sides of the clamping plate 12. These are made of rubber and clamp the bucket teeth, mitigating the reaction force generated during grinding. A chute 19 is provided within the fixed frame 3, and the slider 5 slides within it. The chute 19 and the slider 5 cooperate to define the movement trajectory of the docking assembly 6. Universal wheels 20 are installed at the bottom of the workbench 1 to assist in moving the grinding equipment to a designated location for work.

[0036] Working principle: Before grinding the bucket teeth, first select the clamping plate 12 that matches its shape and wear degree, first control the rotating block 14 to rotate counterclockwise through the limiting groove 17 on the side of the docking shell 2 11 on the current equipment, and slide the docking shell 2 11 out from the docking shell 1 10. After removing the current clamping plate 12, align the docking shell 2 11 of the clamping plate 12 with the docking shell 1 10 on the equipment and insert it. When just inserted, the docking block 13 squeezes the rotating block 14 to make it rotate counterclockwise. When the two docking blocks 13 When the internal empty grooves 16 are aligned to form a complete circular groove, the spring telescopic rod 15 pulls the rotating block 14 to rotate clockwise, so that the rotating block 14 clamps the empty groove 16, completing the installation of the clamping plate 12, and placing the bucket tooth in the center of the clamping plate 12. The motor 9 is started to drive the gear 7 to rotate. The rotating gear 7 controls the rack plate 8 to move the slider 5 and the docking assembly 6 inward, so that the buffer pad 18 on the clamping plate 12 clamps the bucket tooth, and the bucket tooth can be ground through the grinder body 2.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
