Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the polishing limiting device comprises a limiting block 1 and an adapter 2; the adaptor 2 is detachably connected with the grinder; the paired limiting blocks 1 are symmetrically connected and arranged on two sides of the adapter piece 2; the bottom of the limiting block 1 is attached to the surface of the base material to be processed.

Specifically, the adaptor 2 can be processed with a caulking groove structure, the head cover of the grinder 3 is clamped in the caulking groove, and the head cover and the caulking groove can be fixed in position through modes such as embedding friction, screw fixation or bonding; after the position fixing is completed, the inclination angle of the grinder 3 is the same as the usual free hand-held state, and the grinding wheel 32 is maintained at an inclination angle while the grip handle 31 is held, thereby grinding with the edge of the front end thereof; stopper 1's effect lies in, can guarantee through self and the laminating of waiting to process the base metal that the direction of polishing of emery wheel is parallel with the face, has also restricted the height of emery wheel 32 minimum simultaneously, avoids polishing excessive condition to utilize simple limit structure, let the abrasive machine of hand-held type accomplish higher machining precision and stability, equipment upgrading is with low costs, easy operation easily learns.

The adapter 2 is arranged above a grinding contact area of the grinding wheel; the limiting block 1 is arranged on the side face of the grinding wheel in a shielding mode.

The adaptor 2 can serve as an upper shielding piece during grinding operation, so that the probability that the burst debris splashes upwards to the position near the eyes of an operator is reduced, and the operation safety is improved; stopper 1 that both sides set up can promote the stability of stop device location with the help of the biplane on the one hand, and on the other hand can reduce piece to splashing of side to reduce the influence to the place around, clean maintenance is more convenient.

As shown in fig. 2 and 3, the bottom of the limiting member 1 is provided with an installation groove 11; a roller 12 is arranged in the mounting groove 11; the side wall of the mounting groove 11 is provided with an adjusting hole 13 in a penetrating way; a bearing block 14 is movably arranged in the adjusting hole 13; the rotating shaft of the roller 12 is connected with the bearing block 14 in a matching way; when the limiting member 1 is pressed, the bearing block 14 moves in the adjusting hole 13, and drives the roller 12 to retract into the mounting groove 11.

When the roller 12 is not stressed, part of the roller is exposed out of the mounting groove 11, so that a rolling movement effect can be provided when the roller is initially contacted with the base material, the rough adjustment of the working position of the grinding wheel is realized, when an operator presses the grinding machine, the roller 12 retracts into the mounting groove 11 under the reverse force of the surface of the base material, and the bearing block 14 also movably moves upwards in the adjusting hole 13 in the process; certain sliding damping can be arranged between the bearing block 14 and the adjusting groove 13, so that the roller 12 can retract when the extrusion force is greater than the sliding friction force on the bearing block 14, and the limiting device can align the grinding wheel with the position to be polished by utilizing stable rolling adjustment after primary positioning.

The adjusting hole 13 is obliquely formed; an included angle of 45-60 degrees is formed between the length direction of the adjusting hole 13 and the vertical direction.

When the bearing block 14 is changed to a certain height in the vertical direction, the more the adjusting hole 13 is inclined, the longer the moving stroke in the hole is, so that the adjusting precision can be improved, the lifting adjustment of the working surface of the grinding wheel is more stable, and the hand movement of an operator also has larger adjusting adaptation space.

An elastic piece 15 is further arranged inside the adjusting hole 13; the elastic member 15 is connected and arranged between the bearing block 14 and the inner wall of the upper end of the adjusting hole 13.

The elastic member 15 can keep the bearing block 14 at a lower position by its own thrust, thereby making the position of the roller 12 in the extended state more stable.

A cleaning brush 16 is arranged at the front end of the limiting piece 1; the tip of the cleaning brush 16 is attached to the surface of the base material to be processed.

The cleaning brush 16 is used for pushing forward chips and other impurities away in time when the polishing limiting device moves near the surface of the base material, so that the work of the grinding wheel 32 is less interfered, and the polishing precision is improved.

As shown in fig. 4, (a) is a state when the roller 12 is just in contact with the surface of the base material, and (b) is a state when the operator presses the grinding stopper to retract the roller 12 against the urging force of the elastic member 15, and the working portion of the grinding wheel 32 is lowered to be flush with the base material, so that the raised portion can be ground clean.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
