The present invention relates to a jig for rotating workpieces of a laser processing machine, and in particular, an object of the present invention is to provide a dedicated jig suitable for rotationally supporting a tube when cutting a large tube on a workbench.

Conventionally, when cutting a large pipe, a mechanical cutting using a cutting machine or diamond, etc. has been made, which is cumbersome and requires a lot of time and has problems in dimension management.

After that, the laser processing machine was provided and the laser body oscillated therefrom was able to cut the tube more easily and quickly, but in order to scan the laser around the tube, the tube had to be rotated. Since the device was not provided to rotate the tube by hand, it was very difficult to perform precise cutting as well as other inconveniences and inconveniences.

Accordingly, an object of the present invention is to solve the conventional problems as described above, and at the same time to provide a rotary support jig for holding and turning both ends of the tube to be processed.

Detailed embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in Figs. 2 and 3, a pedestal 3 of a predetermined length having a slide guide 3a is fixedly installed on the work table 2 of the laser processing machine. On both sides, bases 4 and 5 through which the fixing bolts 6 were coupled to one side were installed to slide.

Then, the bracket 7 on the one side base 4 is coupled to the stepping motor 8, the rotational speed and the angle is controlled by a separate controller 15, while the end of the rotating shaft to the size of the circle on the concentric circle Drive side support for holding one side end of the workpiece having the clamping portion 10a at the front end of the variable adjustment and having the rear end hinged as a tension spring body 10b and the three finger rods 10 hinged are divided at the same angle. (9) was fixedly installed (see Fig. 4).

In addition, a driven side support 11 having three finger rods 12 at the same angle is also fixedly installed on the other shaft base 4, and the fifth end of the finger 12 of the driven side support 5 As shown in the figure, the roller 13 was installed to allow the tubular body 14, which is the workpiece to be held therein, to be idling, and the rear end was elastically installed as the tension spring body 11b.

Looking at the operating state of the present invention configured as described above are as follows. First, loosen the position fixing bolt 6 penetrated to the side of the base 5 and move to the left or right along the guide portion 3a on the pedestal 3 to move the position fixing bolt to the length of the workpiece 14. Let it be.

Subsequently, the finger rod 10 of the driving side support 9 of the base 4 set in advance is opened (at this time, it is tensioned by the tension spring body 10b and the clamping portion 10a at the tip of the finger rod 10 is concentric). After the one end portion of the workpiece 14 to be positioned in a concentric circle, the distal end of the tube 14, the roller 13 of the tip of the finger rod 12 of the driven shaft support (11) And the roller 13 at the tip of the finger 12 by the tension of the tension spring body 11b to support the tube body 14 at this time. The bolt 6 on the side of the base 5 is tightened to be in close contact with the guide portion 3a to fix the base 5 so as not to move on the pedestal 3.

After mounting in this way, the worktable 2 is moved to position the cutting target portion under the focus mounting nozzle 1 of the laser processing machine, and the stepping motor 8 is rotated as a controller 15 at a circumferential speed suitable for the thickness of the tube. In addition, the drive shaft support 9 coupled to the rotating shaft of the motor is rotated at a constant speed while holding the workpiece 14 to be rotated.

At this time, the laser injected from the focus mounting nozzle is scanned on the whole circumference of the rotating tube 14 to perform the cutting process, and if the stepping motor is controlled while moving the lower worktable 2 in the X direction, the length of the tube is It is also possible to make partial cutting along the direction at daily intervals.

The present invention is constructed and operated as described above, the drive shaft support and the driven shaft support is installed on the pedestal to support the workpiece to be rotatable form, and the tube is rotated accurately without deviation compared to the conventional manual rotation method It is possible to perform an extremely precise cutting operation, the tube can be rotated by varying the speed as a stepping motor has an exceptional effect that can be cut by changing the tube of any thickness at a speed suitable for cutting.

Claims (1)

In constructing a device that is fixedly coupled to the work table 2 to support and rotate the tubular workpiece, the pedestal 3 having the slide guide portion 3a in the upper longitudinal direction is fixedly coupled to the work object, On both sides of the guide portion 3a, a base 4 and a 5 are provided to be detachably fixed by penetrating the position fixing bolt 6 on one side, and a stepping motor 8 supported and fixed to the bracket on the one side base 4 is provided. On the axis of rotation, the drive side support 9 for the tubular holding in which the hinged portion 10a at the front end and the three hinged finger rods 10 in which the tension spring body 10b is installed at the rear end are divided at the same angle. To the other side base (5), the tension spring body (12b) is installed on the rear end and the three rollers (13) with the roller 13 at the front end is hinged to be hinged to the divided position at the same angle Leveling characterized in that the driven shaft support 11 for the support is fixed It turned jig for rotating the workpiece support machines.
