Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a torch holding mechanism, and more particularly, to a constant distance between the torch tip and the body to be cut when the torch tip is moved to a different position on the body to be cut such as a pipe. For new improvements for.

[0002]

[Prior art]

 As a torch holding mechanism of this type that has been conventionally used, the configuration shown in FIG. 3 is generally adopted. That is, what is denoted by reference numeral 1 in FIG. 3 is a rotary shaft that can be rotated left and right by a motor (not shown), and a longitudinal torch 2 is provided at an end of the rotary shaft 1. A to-be-cut object 3 made of a pipe or the like is arranged below the torch tip 2a of the torch 2.

In the above-described configuration, when the torch 2 is actually used to cut the body 3 to be cut using the fire (not shown) generated from the torch tip 2a, first, the torch 2 is not rotated vertically. If the torch tip 2a is set to the second position B and the distance D between the torch tip 2a and the surface 3a of the body to be cut 3 is set to a predetermined amount, the torch 2 is set to the first position A and the third position C, and The cutting can be performed at a position different from the 2 position B.

[0004]

[Problems to be solved by the device]

 Since the conventional torch holding mechanism is configured as described above, there are the following problems. That is, since the torch was fixed to the end of the rotating shaft and supported at one point, if the cutting position was changed by rotating the torch to the left or right, the distance between the tip of the torch and the surface of the object to be cut. Change and the cutting ability changes. Therefore, the rotation axis must be moved up and down along the direction shown by the arrow in Fig. 3 to adjust the distance to be constant at any position. There wasn't.

The present invention has been made to solve the above problems, and in particular, when the torch is rotated to move the tip of the torch to a different position on the body to be cut such as a pipe. An object of the present invention is to provide a torch holding mechanism that makes the distance between the tip of the torch and the body to be cut constant.

[0006]

[Means for Solving the Problems]

 A torch holding mechanism according to the present invention includes a first rotating shaft rotatably mounted on a fixed body through a motor, a linear guide mounted on the first rotating shaft, and a slidable mount on the linear guide. Torch, a second rotating shaft provided on the fixed body and located away from the first rotating shaft, a protrusion provided on the upper end of the torch, and the second rotating shaft and the protrusion are connected to each other. And a connecting body for the linear guide, and the torch slides with respect to the linear guide through the connecting body by the rotation of the linear guide.

[0007]

[Action]

 In the torch holding mechanism according to the present invention, the torch is provided on the first rotating shaft via the linear guide, and the upper end of the torch is connected to the second rotating shaft via the connecting body, so that the torch is not vertical. When rotated to either the left or right position, the torch slides downward in this linear guide, so the distance D between the tip of the torch and the surface of the object to be cut is always constant, and the torch is uniform at any position on the surface. Can be cut. Moreover, the electric position control of the torch height is not required, and the entire control system is simplified.

【Example】

 Hereinafter, preferred embodiments of the torch holding mechanism according to the present invention will be described in detail with reference to the drawings. It should be noted that the same or equivalent parts as those of the conventional example are designated by the same reference numerals for description. FIG. 1 is a block diagram showing a torch holding mechanism according to the present invention, and FIG. 2 is a sectional view. A reference numeral 10 in FIG. 1 is a plate-shaped fixed body, and the fixed body 10 is provided with a first rotating shaft 1 rotated by a motor 11 via a first bearing 12. ..

The first rotary shaft 1 is connected to a gear type motor 11 fixed to the fixed body 10, and a linear guide 14 is provided at an end of the first rotary shaft 1, and the linear guide 14 is provided. The torch 2 is provided slidably in the direction of the arrow.

A to-be-cut object 3 made of a pipe or the like is provided below the torch 2, and a projection 15 is provided on an upper end 2b of the torch 2. A second rotary shaft 17 is rotatably provided at an upper portion of the fixed body 10 at a position separated from the first rotary shaft 1 via a bearing 16, and the second rotary shaft 17 and the projection 15 are provided. Are operably connected via a connecting body 18.

Next, a case will be described in which the torch 2 is actually moved to change the cutting position of the body 3 to be cut in the above-described configuration. First, when the linear guide 14 is rotated by the motor 11 and the torch 2 is held in the vertical state of the second position B, the distance D between the torch tip 2a and the surface 3a is obtained.

Next, in order to change the cutting position of the body 3 to be cut, the linear guide 14 is rotated through the motor 11 and the torch tip 2a is moved to the first position. The torch 2 slides downward as the connected body 18 pivots, and the distance D becomes the same as in the second position B. Further, the distance D is the same when the torch tip 2a is moved to the third position C.

[0013]

[Effect of device]

 Since the present invention is configured as described above, the following effects can be obtained. That is, the torch itself is slidably held by the linear guide, and at the same time, the upper part of the torch is movably held by the fixed body by the connecting body, so that the torch itself slides downward, The distance between the tip of the torch and the surface of the body to be cut can be kept constant even at the rotating position and the vertical position. Therefore, there is no need to electrically control the height of the torch tip, and the torch holding mechanism is greatly simplified.
