A laser processing machine is provided in which a machining tool is automatically exchanged with a laser processing tool to be mounted to a processing head thereof to perform machining operations such as tapping to works. A machining tool 70 which is exchangeably clamped to a mounting section 510 of a processing head 50 of a laser processing machine has a body 720 and a piston member 730 in the body 720, and the piston member 730 supports an air motor 740, a reducer 750, a tool chuck 760, and a tap 762. Air is sent to the air motor 740 from an air source 551b by switching a valve, and an assist gas for a normal or reverse rotation is sent from an assist gas source 554b to the upper portion of the piston member 730, so that a tap is lowered to perform tapping to a work.

A technique of easy manufacture of a column and a bed of a machine tool in a short time is provided by having an assembly structure of sheet metal members. A column body of the machine tool is constituted by combining a front member 110 with a rear member 130 and mounting a side cover. Its inside is reinforced by a plurality of ribs 150, 160. Each of the members is made by precision laser machining of sheet plate materials. The column body is assembled by inserting projection portions provided on one member into slits formed on the other member.

A device for improving the efficiency of operation for aligning the optical axis of mirrors disposed in an optical path for laser transmission in a laser beam machine. The laser beam output from a laser oscillator of a laser beam machine is transmitted via multiple mirrors disposed in the optical path thereof to a torch. A mirror for receiving the laser beam from the mirror is removed and a laser beam detecting device is attached in replacement thereof. The laser beam is passed through a cross-shape target, a portion of which is branched and taken as image by a laser beam detecting picture element. The operator operates adjusting screws and to change the tilt angle of the mirror while watching image data, so as to align the optical axis of the laser beam.

The invention provides a rotation-type changer of torches and nozzles for a laser beam machine having a movable table. The automatic tool changer 100 of a laser beam machine is equipped with a plurality of torch holders 160 and a nozzle changer 170 disposed on the magazine 150. The working head 40 moves in a Y-axis direction perpendicular to the paper plane and in a Z-axis direction. The torch holder 160 storing the torch to be exchanged is rotated along the Y-axis path line and the working head 40 is lowered to exchange the torch.

The invention provides a method for creating a three-dimensional solid model from a two-dimensional projection drawing created on a CAD screen via a simple operation. Reference points P1, P100 and P200 are respectively selected on a front view, a plan view and a right side view of a CAD screen. Line L1 is selected in step (1), and points P100 and P101 are selected in steps (2) and (3). By selecting lines L200 and L201 in steps (4) and (5), the coordinates of three-dimensional elements L300 and L301 are recognized. Thereafter, the procedure is repeated sequentially to recognize the whole shape of the product via points and lines. By recognizing closed shapes surrounded by lines as surfaces, it becomes possible to create a three-dimensional solid model via a simple method.

The invention provides a laser beam machine having a light path duct with improved dust proof property. A light path system 1 of a laser beam machine comprises a light path duct 10 having a U-shaped cross-section with the upper end opened, wherein the opening portion is covered by a steel belt 30. The laser beam extraction unit 50 traveling on the light path duct 10 in the direction of arrow A elevates the steel belt 30 and extracts the laser beam from the light path duct 10. The steel belt 30 has a guiding projection 32 disposed at the center thereof. The laser beam extraction unit 50 has a guide roller 64 disposed below the steel belt 30 and a guide roller 62 having a V-shaped groove 62a for engaging the projection on the steel belt 30, thereby preventing displacement of the steel belt.

The invention provides a device for improving the positioning accuracy of a linear motor. A stator 20 is designed to have two kinds of magnets with different surface magnetism arranged alternately and at uniform intervals along the linear moving direction. A moving member 30 is disposed movably in the linear direction while maintaining a uniform distance from the stator. A detector head 50 formed integrally with the moving member 30 detects the magnetic flux of the stator 20 and sends the data to a control unit 60. The fixed laser length measuring machine 100 irradiates a laser beam LB to a target 110 attached to the moving member, and using the reflected light, measures the distance between the laser length measuring machine and the target highly accurately. The position of the stator 20 used as the magnet scale and the highly accurate position data measured by the laser length measuring machine 100 are compared so as to compute the correction data corresponding to the position of the stator, and the computed value is stored in the storage unit 70 to be utilized for the positioning of the motor.

The invention provides a method and an assembly jig for fixing a pipe structure unit manufactured by assembling tenons and mortises formed on end portions of pipes to a building structure. The pipe structure unit 10 comprises large-diameter pipes 20, 30, 40 and 50 and small-diameter pipes 60, 70 and 80 which are assembled on an assembly jig 100 by assembling tenons and mortises formed in advance on the ends of the pipes via laser machining. The pipes are provided with mounting portions disposed on the other ends thereof, which are used to temporarily tighten the pipes to flanges of pillars 200 and 210. A jack 130 of the assembly jig 100 is lifted to compress the gaps formed at the tenons and temporarily tightened portions, and the pipes are fully tightened in this state. If necessary, the joint portions of the pipes are welded via spot welding and the like to complete the building structure.
