Embodiment Construction

[0020] Next, a machining center-type composite machining device as an embodiment of the present invention will be described with reference to FIGS. 1 to 6 . The device consists of a worktable (moving platform) 11 that moves along the X-axis direction, a moving platform 31 that moves along the Y-axis direction on the beam 21 above it, and a mobile platform that moves along the Z-axis direction on the moving platform 31. Table 32, a rotary table 33 provided on the mobile table 32 to rotate in the direction of the C axis, a rotary table 34 provided on the rotary table 33 to rotate in the direction of the B axis, and a spindle 35 of a rotary mounting tool provided on the rotary table 34 constitute. The turntable 34 has a motor that rotates the main shaft 35 .

[0021] The main shaft 35 can selectively mount a cutting tool 51 and a friction stir welding tool 52 . The spindle 35 can rotate at a speed suitable for the tools 51 , 52 . The tool storage device 40 is not shown, but ca...

Abstract

The present invention provided a compound machining device and friction stir bonding method. A machining device comprising five axial kinetic coordinate systems that can be controlled simultaneously, three axes of which are linear moving axes and two axes of which are rotary axes, with one axis of the five axes being provided with a tool rotating function, whereby said machining device is equipped with a cutting tool 51 and a friction stir welding tool 52. The current value observed when a large-diameter portion of said tool 52 contacts the work object is set in advance, and by observing the torque current of the rotary shaft of the tool 52 during friction stir welding, the insertion depth of the tool 52 can be controlled by maintaining the observed torque current above the preset current value, thus providing a good weld. A single device can provide both the cutting and the welding. Thus, it is possible to reduce equipment cost, installation space, plant area, lead time and production cost.

Description

[0001] This application is a divisional application of an invention patent application filed by Hitachi, Ltd. on February 15, 2001 with the application number "01104536.1" and the title of the invention "composite processing device and friction stir welding method". technical field [0002] The present invention relates to a device and method for cutting metal materials and friction stir welding. For example, it is suitable for the processing and assembly of mechanical parts and structural parts. Background technique [0003] Processing and assembly of mechanical parts and structural parts, etc. are processed by respective processing equipment, cutting machine tools are used for cutting processing, and various welding and joining devices are used for joining and assembly. [0004] Composite processing performed by cutting machine tools is almost all composite processing in cutting processing such as turning and rotary tool processing on a composite lathe, and rotary tool pro...
