Description

[Detailed explanation of the invention] In order to use a tube such as a xenon tube for purposes such as light beam welding where light is focused correctly, the position of the tube as a light source must be adjusted three-dimensionally. No.

The present invention attempts to meet that need.

The explanation of the figure is as follows.

This invention has a vertical movement shaft 9 and a horizontal movement shaft 1 in a part of the main cylinder 15.
2. An operation box containing a longitudinal movement shaft 13 is provided, and in order to move the tube G up and down, the vertical movement piece 5 to which the left and right movement piece 3 to which the tube is attached is pivoted is rotated by rotating the vertical movement axis. To move the tube back and forth, the vertical movement plate 5 is attached to the end plate 7 by rotating the back and forth movement shaft. This is done by rotating the bulb around the moving shaft 9, and in order to move the tube horizontally, the horizontal moving shaft 12 screwed into the vertical moving plate 5 is moved forward and backward toward the horizontal moving piece 3 and pivoted to the vertical moving piece. This is done by rotating the left and right movable piece 3 around a point.

The following will be explained. Reference numeral 1 denotes a xenon tube which is suspended and fixed to the side surface of the left and right moving piece 3 by means of a mounting piece 2.

An operation box is provided on the circumference of the main cylinder 15, and a vertical movement shaft 9 and a longitudinal movement shaft 13 are fitted horizontally into the side plate 11 of the main cylinder 15, and are pivotally connected to the vertical movement shaft 9. )
A longitudinal movement plate 8 is provided so as to be able to rotate, and a longitudinal movement shaft 13 is provided.
An eccentric cam 14 is fixed to the end and positioned so that its circumferential surface contacts the inner surface of the forked portion of the longitudinal motion plate.

(b) For the back and forth movement of the tube. Therefore, if the back and forth movement shaft 13 is rotated, the back and forth movement plate will swing from side to side in Fig. 2 (back and forth in Fig. 1) centering on the vertical movement axis as shown in Fig. 2. The tube also moves back and forth (perpendicular to the plane of the paper).

(b) The vertical movement shaft 9 and the longitudinal movement axis for vertical movement of the tube are respectively pivotally attached to one side plate 11 of the operation box, and the horizontal movement axis 12 is separated from the one side plate 11 and the longitudinal movement plate 8 and can directly move up and down. It is screwed into plate 8.

To mount the rotary cam 10 at right angles to the end of the vertical movement shaft 9, the eccentric pin 16 is rotatably inserted, and its foot is inserted into the horizontal hole called the cutout hole 19 (FIG. 4) of the end plate 7. insert.

Therefore, when the vertical movement shaft 9 is rotated, the legs 17 move up and down, so the vertical movement plate 5 fixed to the end plate moves up and down, and together with the left and right movement pieces 3 attached to the arms 18 and 18 that come out, the tube moves up and down. The ball also moves up and down.

(c) The left-right movement shaft 12 for left-right movement of the tube is screwed into the vertical movement plate 5, and its tip is brought into contact with the lower part of the left-right movement piece 3.

A push spring 6 is provided above the pivot shaft 4 of the left-right movable piece and the upper part of the vertical movable plate 5 so as to separate the two.

Therefore, by moving the left and right movement shaft 12 forward and backward toward the left and right movement piece 3, the left and right movement piece 3 and the tube 1 are moved around the pivot shaft 4.
moves left and right across the page.

As described above, in the present invention, the tube is attached to the left-right moving piece 3, the left-right moving piece is attached to the vertical moving plate so as to be rotatable around the axis by a pivot shaft, and the vertical moving plate is fitted so as to be able to move up and down. The longitudinal movement plate is pivotally attached to the vertical movement shaft, and is rotatable back and forth around this axis by the longitudinal movement axis.Both the vertical movement axis and the longitudinal movement axis operate the main cylinder. Since it is attached to one side plate of the box, by rotating each shaft in the operation box, the tube can be tilted or moved in any direction: left and right, up and down, and front and back.

Therefore, by moving the tube in three-dimensional directions, it is possible to adjust the position to the most appropriate position for condensing and reflecting light.
