Description

Grinding tool

This creation relates to abrasive tools, and in particular to an abrasive tool that enhances the transmission structure.

A general grinding tool includes a rotating seat and an abrasive piece disposed on the rotating base. The rotating base is connected to the power source and driven to rotate by the power source. When the rotating seat rotates, the rotating piece can be further rotated to grind the working object. The abrasive sheet will wear out during use, and it is a consumable that must be replaced depending on the wear condition. Therefore, the abrasive sheet is generally fixed to the rotary seat by attaching. However, the attachment method of the attachment is not stable, so that during the grinding process, the rotation seat and the polishing sheet are easily separated and slipped.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

It extends in an arc along the outer edge of the connecting surface 302. The grinding ring piece 100 is superposed on the joint surface 301 of the joint ring piece 300, and the grinding ring piece 100 is attached to the joint surface 301 of the joint ring piece 300 with respect to the other side of the sanding surface 101, thereby exposing the sanding surface 101 to Bonding surface 301. A second attaching structure 420 corresponding to the first attaching structure 410 is stacked on the connecting surface 302 of the grinding ring 100. In the embodiment, the first attaching structure 410 and the second attaching structure 420 are preferably The ground is the corresponding devil's structure. The first attaching structure 410 and the second attaching structure 420 are attached to each other, and the connecting ring piece 300 is fixedly received in the receiving slot 210. Each of the positioning ribs 310 of the connecting ring piece 300 is respectively embedded in a corresponding recessed groove 220 in the receiving groove 210 of the rotating base 200.

Referring to Figures 5 and 6, the abrasive tool 10 of the present invention is coupled to a power source 20 in use, and the vehicle hub 30 can be ground by the rotation of the power source 20. The power source 20 can be, for example, an electric wrench, an air wrench, an electric drill or a pneumatic drill. The power source 20 includes a drive shaft 21. In the present embodiment, the drive shaft 21 is preferably a square shaft, and the side of the drive shaft 21 A spherical latch 22 corresponding to the aforementioned snap-fit structure 501 is provided; however, the present invention is not limited thereto. When the snap-fit structure 501 is in the form of a tongue, the side surface of the drive shaft 21 may also be provided with a corresponding buckle groove. . The drive shaft 21 is inserted into the metal sleeve 500 embedded in the tip end 202 of the rotary base 200, and each of the spherical latches 12 is fastened to the corresponding snap-fit structure 501 to fix the rotation of the drive shaft 21 to the grinding tool 10. The inner edge of the grinding ring piece 100 is sleeved on the axle 31 of the hub 30. When the power source 20 drives the rotating base 200 to rotate, the rotating base 200 drives the grinding ring piece 100 to rotate along the axle 31 to polish the hub 30.

The grinding tool 10 of the present invention has the grinding ring piece 100 capable of quickly changing the grinding ring piece 100 in an attached manner by the first attaching structure 410 on the connecting ring piece 300 and the second attaching structure 420 on the rotating base 200. And the grinding ring piece 100 and the rotating base 200 are radially positioned by the positioning ribs 310 on the connecting ring piece 300 being embedded in the slot 220 of the rotating base 200, thereby avoiding slippage, so that the rotating base 200 can actually drive the grinding ring piece 100. Rotate. Moreover, when the present abrasive tool 10 is pressed against the workpiece for sanding, the support ribs 230 can be pushed against the attachment ring sheet 300 to provide a supporting force so that the abrasive ring sheet 100 can be pressed against the workpiece.
