Description

[Detailed Description of the Invention] This invention relates to a stone grinding device, and more particularly to a stone grinding device suitable for use in chamfering, burring, grooving, etc. of stone.

Traditionally, chamfering, burring, grooving, etc. of stone materials are...
It is done manually using a manual grinding head such as a grinder.

However, in such conventional manual grinding, the feeding direction of the carcass is solely controlled by the operator's control, so it is important to maintain the flatness and straightness of the grinding part in good condition. It is difficult to do so.

Furthermore, the operator is required to apply a grinding force to the grinding head and also support the weight of the grinding head, which poses a problem in that the work is accompanied by great fatigue.

This idea was devised in view of the above-mentioned conventional problems, and aims to make manual grinding work lighter.
An object of the present invention is to provide a stone grinding device that can improve grinding accuracy.

In order to achieve the above object, the stone grinding device according to the present invention includes a manual grinding head that includes a stone and a stone drive unit, a running frame that supports the manual grinding head and includes a running roller, and a drive frame that is fixed to the stone. It has a guide rail that holds the traveling rollers of the traveling frame in a removable manner, supports the traveling frame and the manual grinding head, and allows them to be guided in the linear movement direction, and allows manual grinding to be carried out manually by an operator. The head can be moved in a straight line to grind stone.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 shows a grinding device 1A as a first embodiment of this invention.
FIG.

The grinding device 1A includes a grinding head 10, a traveling frame 20, and a guide rail 30, and is capable of chamfering a stone 2.

The grinding head 10 is equipped with a stone 12 on a main shaft 11, and a starter switch 14 provided in a handle 13 activates a built-in stone drive unit, making the stone 12 rotatable. A person can apply a moving force and a grinding force via the handle 13.

As shown in FIG. 2, a support bolt 21 is fitted into the center of the traveling frame 20, and the tip of the support bolt 21 is fixed to the side of the grinding head 10.

The grinding head 10 has a rotation axis S formed by a support bolt 21.
It is possible to swing relative to the traveling frame 20 about the center.

Arms 22.2 are provided on both sides of the traveling frame 20, respectively.
3 is extended, and a running roller 24.25 is rotatably provided at the tip of each arm 22.23.

The running roller 24 is inserted into the C-shaped running guide path 31 of the guide rail 30 so as to be transferable, and its inner end surface can be locked by a locking part 32 formed at the opening of the running guide path 31. It is said that

Here, the guide rail 30 includes a fixed plate 33 that is integrated at one end and comes into contact with one end surface of the stone 2, and a locking plate 33 that is loosely fitted into the locking part 32 and the engaging part 34 at the other end. By sandwiching the stone 2 from both end faces with a fixing screw 36 that is screwed into the mating plate 35 and presses the other end face of the stone 2, the traveling direction of the traveling guide path 31 can be arranged parallel to the chamfered ridge of the stone 2. It can be fixedly placed on the stone 2 under such conditions.

Moreover, the running roller 25 is connected to the guide rail 30 of the stone material 2.
is adapted to be movably brought into contact with a surface perpendicular to the surface on which it is fixedly arranged.

Next, the operation of the first embodiment will be explained.

The grinding head 10 is placed on the travel guide path 31 of the guide rail 30.
The running rollers 24 of the running frame 20 supporting the are inserted.

Next, with the front surface of the stone 12 of the grinding head 10 facing the chamfered edge of the stone 2, the guide rail 30 is placed on one side of the stone 2 using the fixing plate 33, the engagement plate 35, and the fixing screw 36. Fixed placement.

Here, the running guide path 31 of the guide rail 30 is made of stones 2
is placed parallel to the chamfered edge of.

Next, by manually operating the handle 13 of the grinding head 10, the stone 12 is pressed against the chamfered edge of the stone 2, and the start switch 14 is turned on to rotate the stone 12 and apply a running force to the running frame 20. , traveling roller 24
is locked by the locking portion 32 of the guide rail 30, the running roller 24 rolls along the guide rail 30, and the running roller 25 rolls along the other surface of the stone 2.

That is, the grinding head 10 and the traveling frame 20 are
The stone 2 is moved in a straight line in the direction of the chamfered ridge while the chamfer angle preset on the stone 12 is maintained correctly.

Here, by swinging the grinding head 10 around the rotation axis S in a plane parallel to the running direction, the inclination angle of the stone 12 with respect to the running direction changes, and the amount of chamfering of the stone 2 can be increased. It becomes possible.

According to the first embodiment, when the running frame 20 is held by the guide rails 30, the weight of the grinding head 10 and the running frame 20 is reduced by the locking by the locking portion 32 of the running roller 24, and the movement of the running roller 24. Guide route 3
The grinding head 10 is supported by rolling contact with the grinding head 1 and the rolling contact of the running roller 25 with the stone 2, and the operator does not need to support the entire weight of the grinding head 10, making it possible to lighten the work.

Further, the traveling frame 20 is moved along the traveling guide path 3 by the traveling rollers 24 rolling along the guide rails 30.
1, the chamfer formed by the stone 12 has good linearity and flatness.

FIG. 4 shows a grinding device IB as a second embodiment of this invention.
