The present invention relates to a sculpting polishing machine, and more particularly, to a sculpting polishing aid for assisting the polishing of engravings used in metal, non-ferrous metals, precious metals, wood carving processing field and the like.

Generally, carving is also called a carving knife, a carving knife. Sculpture here refers not to the term of art genre, but to the artistic act of engraving. Sculpture is distinguished from the tools used to create sculptures of art genre. It is used for students' art education, metal, non-ferrous metal, precious metal, and wood carving processing. Say the tool.

These engravings are divided into window knife, round knife, chisel, and triangle knife, depending on the purpose of use. A knife is usually used for digging out sharp lines or details, while a round knife is convenient for digging thick lines or digging a large surface. Chisels make changes to the screen when removing unnecessary parts or cleaning up rough surfaces. When used, the trical is convenient for digging out lines.

Engraving is used for a long time or used a lot, if the blade is worn, polished with sandpaper, that is, to be used again.

By the way, there is a problem that can not go constantly unless the skilled person in the case that the engraving degree to wear.

Of course, if you are a student, you do not use a lot, so you can buy new ones. However, if you are a working technician working in metal, non-ferrous metals, precious metals, and woodworking, it is difficult to purchase new ones. This is not easy.

The present invention is to solve the above-described problems, it is an object of the present invention to provide a polishing aid for one piece so that anyone can use the grinding pieces without having to go through a skilled process for polishing separate pieces.

Features of the present invention for achieving the above object is the rear end is fixed to the handle, formed in a cylindrical shape for transmitting the pushing and pulling force of the operator, the front end portion is cut through the fixed piece and the first wrench bolt to pass through A main cylindrical shaft provided with a first screw hole, a reference mark for indicating a reference when rotating, and an elastic ring fixed around the cylindrical shape to be partially cut off; A second screw hole formed to correspond to the second wrench bolt, two third screw holes formed on the left side and a right side, a central hole communicating with the second screw hole at an angle of 90 degrees, and formed therethrough; A fixing part provided with an angular mark indicating an inclination along the periphery of the central hole, and a recess formed along the inner diameter of the central hole and into which the elastic ring is fitted; A bolt-shaped fixing bolt fastened to each of the two third screw holes, a bearing for infinite rotation, and a wheel assembly composed of a wheel with elasticity.

In a preferred embodiment, it is provided to be folded at the lower end of the main cylindrical shaft, and further comprises a polishing angle fixing portion defining the polishing angle.

In a preferred embodiment, the polishing angle of the engraving degree is adjusted by turning the main cylinder shaft by a desired angle.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First Example

The first embodiment relates to an abrasive aid free of vertical angle.

1 is an exploded perspective view of an abrasive polishing aid according to the present invention, the abrasive polishing aid 10 is a cylindrical shaft 12 for transmitting a pushing force and a pulling force of the operator, a high for coupling and fixing each component The government 14, the wheel assembly (16a, 16b, 16c) to enable the endless rotation to reduce the operator's power during polishing, the operator is made of a handle 18 that can be held by hand.

1) cylindrical shaft

Cylindrical shaft 12 is made of a hollow cylindrical shape, the fixing piece 12a for positioning the end of the pushing direction to be fixed by pressing the front end of the engraving to be polished from top to bottom, and the polishing angle of the engraving Reference mark (12b) for indicating the reference when the rotation, the upper part is cut around the cylindrical shaft is fixed while being wrapped around the cylindrical shaft (12c) made of an elastic elastic body, and the first screw hole formed on the top ( P1) is provided respectively. At this time, the first screw bolt (A) for fastening the rear end of the engraving is fastened to the first screw hole (P1).

2) government

The fixing portion 14 includes an angle display 14a for indicating an angle of inclination along the periphery of the hole formed in the front center, a recess 14b formed around the inner diameter of the hole formed in the front center, Second and third screw holes P2 and P3 formed in the inner diameter are respectively provided. At this time, a second wrench bolt B for fastening the engraving shear is fastened to the second screw hole P2.

3) wheel assembly

The wheel assembly includes a wheel 16a made of synthetic resin or rubber having elasticity, a bearing 16b for infinite rotation, and a fixing bolt 16c for fixing to the third screw hole P3.

4) handle

The handle 18 is to be pushed and pulled by a worker when grinding, and is fixed to the rear end of the cylindrical shaft 12.

The handle 18, the cylindrical shaft 12, the fixing portion 14, the wheel assembly (16a, 16b, 16c) by combining the abrasive grinding aid 10 is assembled, the cylindrical shaft 12 and the fixed portion ( At the time of assembling 14, the elastic ring 12c fixed to the cylindrical shaft 12 is inserted into the groove 14b formed at the inner diameter of the hole in the center of the fixing portion 14, and at the same time, a "click" coupling sound is generated. The combination of the elastic ring 12c and the recess 14b facilitates the rotation of the cylindrical shaft 12 to help the rotation of the engraving to be polished during polishing.

Look at the effect of the engraving polishing aid having the above-described configuration.

Figure 2 is a side cross-sectional view of the engraving polishing aid according to the present invention.

Referring to FIG. 2, the carving figure 20 to be polished is inserted into the main cylindrical shaft 12, and then the first hexagon wrench bolt A is rotated by the hexagon wrench to press and fix the engraving piece. Since the back of the sculpture is pressed, the front of the sculpture is slightly lifted up. The second hexagon wrench bolt (B) is rotated and fixed to press the lifted figure.

The operator grabs the handle 18 and contacts the polishing plate (bottom surface of FIG. 2) to polish the engraving 20 while pushing and pulling. After grinding the corresponding portion of the engraving 20, turn the handle 18 to a desired angle while referring to the reference mark (12b) and the angle display (14a). At this time, before turning to the handle, loosen the first wrench bolt (B) somewhat to facilitate the rotation of the engraving, and loosening the first wrench bolt (B) facilitates the turning due to the elastic ring (12c) and the groove (14b). .

2nd Example

The second embodiment relates to a polishing aid having a fixed vertical angle.

Figure 3 is a side cross-sectional view of the engraving grinding aid according to the present invention, showing a side cross-sectional view of the engraving grinding aid is fixed vertical angle at the time of polishing.

3, the polishing angle fixing part 30 is fixed to be folded to the rear end of the main cylindrical shaft 30.

The polishing angle fixing part 30 has a supporting rod 30a which is less affected by gravity downward when polishing, an auxiliary rod 30b which assists the supporting rod and, if necessary, the intermediate joint is folded, and pushes and pulls for polishing. Consists of a wheel 30c for reducing friction and a hinge 30d that can be folded if necessary.

According to a preferred embodiment of the present embodiment described above, there is an advantage that can be polished by rotating the engraving degree exactly to the desired angle, even if you are not skilled by using a polishing angle fixing portion even beginners can easily polish at the same angle as new to provide.
