[invention Title]

PROCESSING DEVICE OF SURFACE PATTERN

[Technical Field] The present invention relates to a processing device of a surface pattern.

[Background Art]

Industrial diamonds refer to any diamond designated for industrial use, which are too poorly coloured or badly flawed to be of value as gems. There are generally two cases for using industrial diamonds: (1) one using crystal type industrial diamonds as a blade of a lathe tool, a die for line drawing, a glass cutter, a bit for a rock drill, a diamond saw, and the like; and (2) the other using powder type industrial diamonds as a polishing powder, a grinding powder, and the like. Industrial diamonds are of vital importance in the industries. Their utility stems from the fact that diamond is the hardest natural substance known. Besides, diamond has high heat conductivity, a low thermal expansion coefficient, and an excellent acid resistance. Because diamond is one of the most important materials in the modern precision machinery industries and thus is considered as a strategic material, demand for diamond increases every year. There are many kinds of tools utilizing industrial diamonds, as follows: a diamond dresser (processing tool for a surface of a grinding stone) , a diamond bite (cutting tool) , a diamond die (cutting tool) , a diamond wheel (grinding tool) , a diamond glass cutter, a diamond needle, and so on. The above industrial tools utilize the inherent features of diamond, i.e., high hardness, excellent anti-abrasion and a low thermal expansion coefficient. The industrial tools using diamond increase precision of industrial products, thereby making a great contribution to improve product quality.

Describing the above tools in detail, a diamond bit refers to a boring bit which uses diamond as a cutting material, a diamond wheel refers to a grinding wheel coupled with diamond by a coupling agent, more particularly, to a grinding tool which is made by sintering micro powders of industrial diamond with artificial resin, and a diamond bite refers to a bite which uses diamond as a blade of a cutting tool. By virtue of the highest hardness and the chemical stability, diamond is a top-level material for mechanical tools. Specifically, when surface roughness is an important factor, a diamond lathe mounted with a diamond bite is used. In other words, if cutting an object to be processed at a high speed by using a diamond bite mounted to a diamond lathe having features of low vibration and high precision, a desired surface roughness can be obtained. A diamond bite can cut most materials, however it is mainly used to cut light metal, soft metal, and precious metal.

Processing devices equipped with the above various tools using diamond are used for polishing work to improve surface gloss of metal or for cutting work to cut metal into various shapes.

A conventional surface processing device is mainly used for polishing work to improve surface gloss and surface roughness of outer surfaces of electronic products or surface contact portions of machinery, thereby providing a soft touch feeling. Especially, the conventional surface processing device enhances surface gloss of keypads or cases of various electronic products, and gives a user a soft touch feeling when holding them. However, the conventional surface processing device just improves surface roughness and gloss by polishing outer surfaces, but cannot form a pattern on a surface. In order to form a surface pattern, an additional pattern forming process should be carried out, which causes increase in cost. Further, when performing a scratching process by using the conventional surface processing device to prevent slip on a surface, the surface becomes just rough, but has no ornamental effect with a poor pattern and no gloss.

Still further, the conventional surface processing device is used to improve gloss and roughness of a metal surface, but cannot be applied to other kinds of materials and is restricted to the surface processing, i.e., cannot be used in various fields.

[Disclosure] [Technical Problem]

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a processing device of a surface pattern that can create various shapes of patterns on a surface of a base material of nonmetal or synthetic resin and improve ornamental effect, by fixedly seating the base material on a jig by a vacuum absorbing force, rotating the base material by using a driving motor mounted on a feeding table which is moved forward, backward, left and right, and rotating a processing tool made of diamond, which is mounted to an up/down moving and rotating main pedestal, in a direction corresponding to a rotational direction of the base material.

The fixing plate is fixed to plural fixing members, and the fixing members are fixed to the feeding table by tightening coupling members to the feeding table.

The support unit further includes a vacuum boss mounted between the bearing support member and the fixing boss of the support unit. The vacuum boss is connected to a vacuum generator by a vacuum connecting tube. The rotating shaft supported by the bearing support member above the vacuum boss is formed with plural vacuum suction holes thereinside. The base material holding part is formed with a plurality of base material absorbing holes communicating with the vacuum suction holes. When the vacuum generator generates a vacuum pressure, air in the base material absorbing holes is sucked out by the vacuum pressure, and the base material is fixedly seated on the base material holding part.

The jig unit further includes a first driving belt support member provided at a lower portion of the rotating gear, and the driving unit further includes second driving belt support members provided at upper and lower portions of the driving gear. The first and second driving belt supporting members prevent separation of the driving belt transmitting a rotational force.

Accordingly, productivity is improved and manufacturing cost is saved.

Further, the processing device of a surface pattern according to the present invention can create various shapes of patterns on the surface of the base material, by mounting the processing tool to the up/down moving and rotating main pedestal, mounting the jig for holding the base material on the feeding table which is mounted below the main pedestal and is moved forward, backward, left and right, and rotating the base material on the jig by using the driving unit while moving the base material forward, backward, left and right and changing the rotational speed of the processing tool mounted to the main pedestal. Depending on the rotational speeds, rotational directions and moving ranges in the forward, backward, left and right of the base material and the processing tool, various shapes of patterns can be formed, and accordingly ornamental effect can be improved.

Further, the processing device of a surface pattern according to the present invention can simplify a structure for rotating the base material and easily regulate the rotational speed of the base material, by mounting the rotating shaft having the rotating gear on the feeding table below the jig, fitting the rotating shaft into the bearing support member having the support bearing, connecting the driving gear of the driving motor and the rotating gear by the driving belt, rotating the jig with the base material by the rotating shaft interlocking with the rotation of the driving motor, and forming patterns on the surface of the base material by the processing tool mounted to the main pedestal while moving the feeding table forward, backward, left and right.

Accordingly, the processing device of a surface pattern of the present invention can be widely used in common machine tools equipped with a main pedestal and a feeding table, only by additionally installing a driving unit and a jig, and manufacturing cost can be saved. Still further, the processing device of a surface pattern according to the present invention is constituted such that a plurality of base material absorbing holes are formed at the base material holding part of the jig on which the base material is seated, the vacuum suction holes communicating with the base material absorbing holes are formed inside the rotating shaft rotatably mounted under the jig, the vacuum boss communicating with the vacuum suction holes are mounted under the support bearing supporting the rotating shaft, the vacuum boss is connected to the vacuum generator through the vacuum connecting tube, and the vacuum generator is operated to suck out the air in the vacuum boss and the rotating shaft so that the absorbing force is applied to the base material seated on the base material holding part through the vacuum suction holes and the base material absorbing holes. Accordingly, since the base material is securely fixed to the base material holding part while improving flatness of the base material and preventing movement of the base material at the high-speed rotation, patterns can be formed accurately on the surface of the base material. Moreover, since the base material is fixed by using the vacuum pressure, a complicated fixing device is not needed, and damage of the base material due to the mechanical fixing method can be prevented.

As shown in Figs. 1 to 5, a processing device of a surface pattern according to the present invention comprises: a processing unit 110 which includes a main pedestal 111 up/down movably provided and a processing tool 113 rotatably mounted to the main pedestal 111; a feeding unit 120 which includes a feeding table 121 provided below the processing unit 110 and a fixing plate 122 mounted on the feeding table 121; a support unit 130 which includes a support bearing 131 provided on one portion of the fixing plate 122 of the feeding unit 120; a jig unit 140 which includes a base material holding part 142 rotatably supported by the support unit 130 to hold a base material 10 of nonmetal or synthetic resin; and a driving unit 150 which includes a driving motor 151 to rotate the jig unit 140.

Here, the base material 10 is a nonmetallic material, such as magnesium or aluminum, or a synthetic resin material of various shapes.

The processing unit 110 is configured such that the processing tool 113 having a processing bite 114 is mounted to a rotating coupling member 112 of the main pedestal 111 which moves up and down, and performs the surface processing work while rotating. The feeding unit 120 is configured such that the fixing plate 122 is mounted on an upper surface of the feeding table 121 which is provided below the processing unit 110 and moves forward, backward, left and right. The fixing plate 122 is fixed to plural fixing members 123, and the fixing members 123 are fixed to the feeding table 121 by tightening coupling members 124 to the feeding table 121.

The support unit 130 is configured such that a fixing boss 136 is mounted on one portion of the fixing plate 122 of the feeding unit 120, and a bearing support member 132 holding the support bearing 131 therein is mounted on the fixing boss

136.

The jig unit 140 is configured such that a jig 141 having the base material holding part 142, on which the base material 10 is seated, is mounted on the support unit 130, and a rotating shaft 144 having a rotating gear 145 under the jig 141 is fitted into the support bearing 131 and is supported by a support ring 148.

Between the bearing support member 132 and the fixing boss 136 of the support unit 130 is mounted a vacuum boss 133 which is connected with a vacuum generator 135 by a vacuum connecting tube 134. The rotating shaft 144 supported by the bearing support member 132 on the vacuum boss 133 is formed with plural suction holes 147 thereinside. The base material holding part 142 provided above the rotating shaft 144 is formed with a plurality of base material absorbing holes 143 which communicate with the suction holes 147. Therefore, the air in the jig 141 and the rotating shaft 144 is sucked out through the base material absorbing holes 143 and the suction holes 147 by a vacuum pressure generated from the vacuum generator 135, so that the base material 10 is fixedly seated on the base material holding part 142.

The driving unit 150 is configured such that the driving motor 151 having a driving gear 152 and a motor support member 155 for supporting the driving motor 151 are mounted on the other portion of the fixing plate 122 of the feeding unit 120, and the driving gear 152 is connected to the rotating gear 145 by a driving belt 153, thereby rotating the jig unit 140 by a driving force of the driving motor 151. It is preferred that a first driving belt support member

146 is provided at a lower portion of the rotating gear 145 of the jig unit 140 and second driving belt support members 154 are provided at upper and lower portions of the driving gear 152 of the driving unit 150, so as to prevent separation of the driving belt 153 which transmits a rotational force.

Hereinafter, the operation of the processing device of a surface pattern will be described.

The processing tool 113 having the processing bite 114 of a diamond material is coupled to the rotating coupling member 112 rotatably mounted to the main pedestal 111 which moves up and down. The fixing boss 136 is mounted on one portion of the fixing plate 122 of the feeding unit 120, and the bearing support member 132 holding the support bearing 131 therein is mounted on the fixing boss 136. After the support unit 130 having the support bearing 131 is mounted on one portion of the fixing plate 122, the rotating shaft 144 extending downward from the jig 141 having the base material holding part 142 is fitted into the support bearing 131, and the support ring 148 is coupled to the rotating shaft 144 to support the same. The rotating gear 145 provided with the first driving belt support member 146 is mounted to the rotating shaft 144.

At this time, the vacuum boss 133, which is connected to the vacuum generator 135 by the vacuum connecting tube 134, is mounted between the bearing support member 132 and the fixing boss 136. A plurality of base material absorbing holes 143 are formed at the base material holding part 142, and the suction holes 147 are formed inside the rotating shaft 144 so as to communicate with the base material absorbing holes 143. Therefore, the vacuum boss 133 communicates with the base material absorbing holes 143, so that the air in the vacuum boss 133 and the rotating shaft 144 is sucked out by the vacuum pressure generated from the vacuum generator 135 and an absorbing force is applied to the base material through the base material absorbing holes 143. After the jig unit 140 is mounted on the support unit 130, the driving belt 153 is coupled to the driving gear 152 disposed on the other portion of the fixing plate 122 and the rotating gear 145 so that the rotating gear 145 interlocks with the driving gear 152. The driving motor 151 to drive the driving gear 152 is disposed under the driving gear 152, and is fixed to the fixing plate 122 by the motor support member 155.

The driving belt 153 can be stably rotated without being separated by the first driving belt support member 146 provided at the lower portion of the rotating gear 145 and the second driving belt support members 154 provided at the upper and lower portions of the driving gear 152.

After the driving unit 150 and the jig unit 140 coupled to the support unit 130 are mounted on the fixing plate 122, the fixing plate 122 is seated on the feeding table 121 which can move forward, backward, left and right. Edge portions of the fixing plate 122 are fixed to the fixing members 123, and the fixing members 123 are fixed to the feeding table 121 by tightening the coupling members 124 to the feeding table 121. Thereafter, the base material 10 is seated on the base material holding part 142 of the jig 141 of the surface pattern processing device 100. The vacuum generator 135 is operated to generate the vacuum pressure to suck the air in the vacuum boss 133 which is connected to the vacuum generator 135 by the vacuum connecting tube 134. Accordingly, the absorbing force is applied to the base material 10 seated on the base material holding part 142 through the suction holes 147 of the rotating shaft and the base material absorbing holes 143, thereby fixing the base material 10 to the base material holding part 142. After the base material 10 is fixedly seated on the base material holding part 142 by using the vacuum pressure, the driving motor 151 of the driving unit 150 is driven to rotate the driving gear 152. The rotational force of the driving gear 152 is transmitted to the rotating gear 145 through the driving belt 153, and accordingly the jig 141 holding the base material 10, which is coupled to the support bearing 131 by the support ring 148, is also rotated.

While the base material 10 is rotated, the main pedestal 111 of the processing unit 110 is moved up and down while being rotated in a direction corresponding to the rotational direction of the base material 10, and the feeding table 121 is moved forward, backward, left and right, thereby creating various types of patterns on the surface of the base material 10. Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. [industrial Applicability]
