Abstract

PURPOSE:To reduce the space for installation of a machine and improve working and functioning properties by providing on the side of a work table a supporting member and a pull rod able to slide in the direction of installation of a horizontal ruler plate and attaching a contact piece opposed to a workpiece held on the surface of the work table to the pull rod. CONSTITUTION:When the dimension for positioning a workpiece W is small and said dimension is within the length of a supporting member 35, cutting position is set using a scale 37 attached to the member 35 and a contact piece 46. To adjust the piece 46, a holder 43 is adjusted by means of a stop screw 44. And when the dimension of the workpiece W is large, exceeding the length of the member 35, a clamp screw 40 is loosened to laterally pull out a pull rod 38 from the member 35, so that the position of the workpiece is set by means of the piece 46 at the end of said rod 38, wherein the positioning of the piece 46 is carried out using a movement indicating scale 41. After that, the rod 38 is fixed by means of the screw 40 and the piece 46 is caused to protrude from the surface of a table to be opposed to the workpiece W.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a workpiece positioning device in a traveling circular saw machine that can make the overall configuration more compact and functional.

(Prior Art) A vertical traveling circular saw called a panel saw exists as a processing machine for cutting large-sized material.

Figure 7 shows the configuration of this processing machine. In the drawing, the workpiece 2' fed onto the horizontal ruler plate 1' at the bottom of the table surface 5' crosses this horizontal ruler plate 1' horizontally. direction, and is positioned by abutting one end against the contact piece 3' on the side of the table surface. Then, at this position, the holding means 4' is operated to press and fix the sheet to the table surface 5', and then the sheet is cut in the longitudinal direction by a circular saw (not shown) that runs protruding from the saw running slit 6'.

The above-mentioned circular saw has a predetermined traveling stroke, and can cut the workpiece 2' in one go with this range as the effective cutting length.

As mentioned above, when cutting with a traveling circular saw,
Before running the circular saw, it is essential to set the abutment piece 3' at an appropriate position and position the workpiece 2' based on this.

Here, the processing position of the workpiece 2', that is, the cutting width, is determined by the distance dimension of the abutment piece 3' from the slit for saw travel, and the abutment is adjusted to correspond to various processing widths. The piece 3' can be moved and adjusted in this width direction. Specifically, a slide guide 7' is disposed in the same direction as the horizontal ruler plate 1', and the abutting piece 3' is provided on the slide guide 7' so as to be slidable therein. Further, a scale plate 8' is attached to the slide guide 7' to indicate the position of the abutment piece 3'.

(Problems to be Solved by the Invention) Incidentally, for convenience of work, the movement adjustment range of the abutting piece 3' is set to correspond to the effective cutting length of the circular saw described above. Therefore, the effective cutting length is 8 shaku (2450
m+s), a correspondingly long slide guide 8' is required.

As shown in the figure, the slide guide 8' appears as a protrusion on the side of the machine, and the installation of the machine is not desirable in terms of space and work functionality.

The present invention has been made in view of the above-mentioned conventional problems, and is intended to provide a workpiece positioning device that can reduce machine installation space and improve work functionality.

(Means for Solving the Problems) In order to achieve the above object, a workpiece positioning device for a traveling circular saw according to the present invention is configured as follows.

That is, the gist of the present invention is that a slit for running a saw is formed in the vertical direction on a work table having a substantially vertical table surface, and a horizontal ruler plate is provided at the bottom of the work table to be orthogonal to the slit for running the saw. In the traveling circular saw machine, a supporting member is disposed on the work table side, and
A drawer rod is provided which can be slid in the direction in which the horizontal ruler plate is arranged by means of this support member, and an abutment piece corresponding to the workpiece held on the work table surface is attached to the drawer rod. Further, the drawer rod is provided with a scale that indicates the amount of sliding movement of the abutment piece.

(Function) By sliding the drawer rod in the direction approaching the saw running slit and storing it in the support member, the drawer rod will not protrude significantly to the side of the table.

Therefore, it is advantageous in terms of machine installation and operational functions.

In addition, if you slide the drawer rod in the direction away from the saw running slit in the opposite way to the above, the drawer rod will protrude to the side of the table, so you can set the position of the contact piece to accommodate wide workpieces. It can be performed. This position setting can be carried out precisely by means of a scale on the drawer rod.
