Description

Cutting Torch Positioning Device {APPARATUS FOR POSITIONING A CUTTING TORCH}

The present invention relates to an apparatus for adjusting the position of a cutting torch for cutting a specimen, and more particularly, the cutting torch including a rotary controller and a lateral position controller connected and controlled by a CNC (Computer Numerical Control). The present invention relates to a cutting torch position adjusting device configured to improve cutting efficiency of a specimen by adjusting up, down, left, right, and rotational positions regardless of the shape of the specimen.

1 is a schematic view showing a cutting torch for cutting a conventional specimen.

Referring to Figure 1, the cutting torch 70 is conventionally connected to the C.N.C (57) is mounted on the vertical position adjuster 50 for adjusting the vertical position of the cutting torch 70. The vertical position adjuster 50 is mounted to the cutting torch 70 at the lower end of the housing 58, and is moved along the guide rails 74 arranged in the lateral direction.

The vertical position adjuster 50 equipped with the cutting torch 70 moves in a direction facing each other along the guide rail 74 or in a direction away from each other according to the size of the specimen 75 to be cut to a cutting position. The arrangement is adjusted.

In addition, the vertical position adjuster 50 includes a guide block 51 and a guide rod for guiding the guide block 51 and the guide block 51 therein as shown in Figure 3, The guide screw 54 is screwed to the threaded through hole 51a of the guide block 51 and the guide rod 59 passes through the through holes 51b of the guide block 51 to guide the block. Guides up and down of (51).

The lower side of the guide block 51 is mounted with a fixed shaft 52 and the fixed shaft 52 is coupled to the cutting torch 70 through the lower plate 58a of the housing 58, The guide screw 54 is rotatably supported by the lower plate 58a, and the guide bars 59 are fixedly supported by the lower plate 58a.

In addition, the upper end of the guide screw 54 is equipped with a drive motor 57 is arranged to control the operation of the motor 57 by the CNC 57, the guide block 51 to the guide screw 54 The vertical position of the cutting torch 70 is adjusted appropriately according to the test piece 75.

Meanwhile, referring to FIG. 4, the cutting torch 70 includes a support body 72, a support holder 73, and a torch injection port 71 mounted at one side thereof, and the cutting position of the specimen 75. Cutting the specimen 75 by spraying a flame at.

However, in the related art, the cutting torch 70 is adjusted only in the up and down direction by the up and down position controller 50, and the position is not adjusted in the left and right directions individually, and at the same time in the rotational direction. The disadvantage is that it can't be adjusted. Accordingly, when the shape of the specimen 75 is not constant with the vertical position adjuster 50 adjusted by the conventional CNC, as shown in FIG. 1, it is not possible to simultaneously start cutting with the cutting torches 70. Since a problem occurs, the cutting operation cannot be performed simultaneously with the two cutting torches 70, and the cutting operation is performed with only one cutting torch 70, so that excessive cutting time is required, and the operation of the cutting operation is performed. It becomes very cumbersome and seriously degrades work efficiency.

In addition, the conventional cutting torches 70 have a problem that the cutting operation is possible only in the direction of the X-axis rail 73 and the cutting operation is not possible in the direction of the Y-axis rail 74, so that cutting operation is not efficient.

The present invention has been proposed in order to solve the conventional problems as described above, enabling simultaneous cutting operation of a plurality of cutting torches for cutting the specimen, cutting the specimen by enabling the cutting operation in the X-axis and Y-axis directions It is an object of the present invention to provide a cutting torch positioning device configured to improve work efficiency.
