Description

Engraving machine of three dimensions}

The present invention relates to a engraving machine, and in particular to a three-dimensional engraving machine that allows to engrave a three-dimensional shape on the required material.

In general, a three-dimensional engraving machine is to engrave a three-dimensional shape of a desired shape on a metal material or a synthetic resin material. The three-dimensional engraver is processed by transferring the material or tool in three directions of the x, y, and z axes that are orthogonal to each other. I am supposed to get a piece of you. Various types of apparatuses for carving such 3D shapes have been developed. However, since most 3D engravers are required to precisely process materials, cutting tools such as end mills have a small depth of cut. It should be used for the precision machining, so there was a disadvantage that takes a long time to process the three-dimensional shape.

An object of the present invention is to provide a three-dimensional engraving machine that can significantly reduce the processing time of the material compared to the conventional.

As can be seen in Figures 1 to 3, the three-dimensional engraver 100 according to the present invention is provided with a bed (110). The bed 110 is a part that stably supports the entire three-dimensional engraver 100, and the first moving path 112 is formed on the x-direction.

As shown, the clamping unit 120 is coupled to the first moving path 112 of the bed 110. The clamping unit 120 is for holding a workpiece made of metal or synthetic resin, and can be moved to a required position by the clamping unit transfer means 130. The clamping unit conveying means 130 is for moving the clamping unit 120 in the x direction, and may be configured in other forms, but as shown, the ball screw 132 and the servomotor 134 for rotating the clamping unit 120. It can be configured as.

As shown in FIGS. 1 to 3, a column 140 is installed near one end of the bed 110. It is preferable to form this column 140 in a substantially sentence shape as shown. As shown, a second moving path 142 is formed along the upper end of the column 140 in the y direction. The second moving path 142 is disposed in a direction perpendicular to the first moving path 112.

The column 140 is provided with saddles 150. The saddle 150 is moved in the y direction along the second moving path 142 and is moved by the saddle conveying means 151 composed of the servomotor 152 and the ball screw 154. The saddle 150 is formed with a third moving path 156 in the z direction, and a fourth moving path 158 is formed parallel thereto.

In the third moving path 156 of the saddle 150, the first spindle 170 is provided to be lifted and lowered by the first spindle conveying means 160 installed in the saddle 150, and the fourth moving path 158 is provided in the fourth moving path 158. The second spindles 190 are liftable by the second spindle transfer means 180 provided on the other side of the saddle 150. Of course, the first and second spindles 170 and 190 are rotatably installed on predetermined lifting members 172 and 192, and the lifting members 172 and 192 are moved. That is, the first spins 170 and the second spins 190 are movable separately. Cutting tools are mounted on the lower ends of the first spins 170 and the second spins 190.

The first spindles 170 and the second spindles 190 are the parts that make up the features of the present invention, and the first spindles 170 are used for roughing, and the second spindles 190 can be used for finishing. This is to shorten the processing time of one material. That is, the roughing tool is mounted on the first spindle 170 to increase the cutting depth, and the roughing tool is then mounted on the second spindle 190 so that the precision tool can be processed to reduce the machining time. This is to maintain the precision. Here, the first spindle transfer means 160 and the second spindle transfer means 180 may also be composed of the servo motors 162 and 182 and the ball screws 164 and 184 similarly to the clamping unit transfer means 130. Of course, in some cases, the first spindles 170 and the second spindles 190 may be integrally connected to elevate the first spindles 170 and the second spindles 190 with one transfer means, but the configuration In this case, since more energy is required than necessary, it is preferable to separately configure them as shown in FIG.

As shown, the first spindle driving means 200 is installed at one side of the first spindles 170, and the second spindle driving means 210 is installed at one side of the second spindles 190, respectively. . The first and second spindle driving means 200 and 210 are for driving the first and second spindles 170 and 190 separately, respectively. The first spindle driving means 200 and the second spindle driving means 210 may be configured by using the servo motors 202 and 212 and belts 205 and 215 for power transmission.

Here, a total of six servo motors 202 and 212 are required, and servo motor control means is required to control each servo motor, which of course must be provided separately.

4 is a side view of the birds.

As shown in FIG. 4, a ball screw coupling part 159 is formed on the rear surface of the saddle 150 to be coupled to the ball screw 154 installed in the column 140. It is moved in the y direction along the two moving paths (142). The saddle 150 is provided with a first spindle feed means 160 made of a servo motor 162 and a ball screw 164, and is spaced apart from the side by a predetermined distance in the same manner as the first spindle feed means 160. Second spindle conveying means is installed. The ball screw 164 here is supported by the bearing 166 provided in the upper end and the lower end, and is provided so that it may rotate in place. The ball screw 164 is coupled to the first and second spindles 170 and 190 which are elevated according to the degree of rotation of the ball screw 164.

5 is a front configuration diagram showing an installation state of the spindle and the spindle driving means, and FIG. 6 is a side configuration diagram thereof.

As can be seen in Figures 5 and 6, the first spindle 170 is installed on the one side of the elevating member 172 to support the bearing 173 so that it can be rotated in place. The pulley 174 is installed on the upper end of the spindle 170. The servo motor 202 is installed near the first spindles 170. The servomotor 202 is for driving the first spindle 170 to rotate, and the rotation shaft 203 is provided with a pulley 204. The belt 205 is connected between the first spindles 170 and the two pulleys 174 and 204 respectively installed on the servo motor 202. The belt 205 is used to transfer the power of the servomotor 202 to the first spindles 170, preferably using a V belt. Of course, in some cases, the servo motor 202 is installed adjacent to the first spindles 170, and bevel gears are installed instead of the pulleys 174 and 204, respectively. You can also pass The installation states of the second spindles and the servomotor are the same as in the first spindles 170 and only the left and right positions are changed.

That is, a material for processing is mounted on the clamping unit 120, and a cutting tool for roughing is attached to the tool mounting part 176 of the first spindle 170, and the tool mounting part 196 of the second spindle 190 is Install the cutting tools for each. After mounting the material and the tool, zero adjustment is performed so that the clamping unit 120, the saddle 150, and the first and second spindles 170 and 190 are in the initial position.

The clamping unit is operated by rotating the ball screws 132, 154 and 164 by controlling the operation of each servomotor 134, 152, 162 and 202 according to a predetermined processing data signal input to the control means after the zero point setting is finished. Move 120 back and forth along the first moving path 112, and at the same time the saddle 150 is moved left and right along the second moving path 142, and along the third moving path (156) The first spindles 170 are rotated while elevating the one spindles 170. Accordingly, the roughing cutting tool installed in the lower tool mounting part 176 of the first spindle 170 performs a rough processing on the material mounted on the clamping unit 120. After roughing, the first spindle 170 is raised by the first spindle transfer means 160, and the driving of the first spindle drive 200 is stopped to stop the operation of the first spindle 170.

Then, after sufficiently lowering the second spindles 190 along the fourth moving path 158, the second spindles 190 are rotated through the second spindle driving means 210. Accordingly, the finishing tool mounted on the lower tool mounting part 196 of the second spindle 190 rotates. After such a process, the operations of the servomotors 134, 152, and 212 are controlled according to the input data from the control means, respectively, to control the clamping unit 120, the saddle 150, and the second spindle 190 x, y. In addition, each of the two spindles 190 is rotated and simultaneously driven to finish the surface of the roughing finished material to obtain a three-dimensional workpiece having a smooth surface.

As can be seen from the above description, the three-dimensional engraving machine according to the present invention is provided with a roughing spindle and a finishing spindle separately, so that the time taken for the engraving of the three-dimensional shape is very short compared to the conventional one, but the precision is not inferior.
