JP 2001-1234 A

  An object of the present invention is to provide an automatic six-face machining system that automatically processes the entire surface of a deformed object such as a casting material, including one general-purpose lathe-type multi-tasking machine and one general-purpose robot. It is.

  The automatic six-face machining system of the present invention replaces the first and second spindles arranged opposite to each other, the milling spindle arranged between the first and second spindles, and the milling spindle tool. A lathe-type multi-tasking machine having an automatic tool changer, a robot arranged in the vicinity of the lathe-type multi-tasking machine, and a setup station having a jig place arranged in the vicinity of the robot, 1 The end face of the workpiece gripped by the spindle is machined to machine one surface including the jig mounting surface, the jig plate is automatically mounted on the jig mounting surface by the robot, and the jig plate is mounted on the second spindle. In addition, it has a configuration for processing the other five surfaces of the gripped workpiece.

  Further, the first spindle is equipped with a free chuck with a grasping range adjustment function capable of gripping a deformed workpiece.

  Further, the setup station includes a jig place and a workpiece pallet.

  The present invention can automatically process the six surfaces of the irregularly shaped workpiece by providing the above-described configuration.

FIG. 1 is a plan view showing an outline of an automatic six-face machining system of the present invention.
The automatic six-face machining system indicated as a whole by reference numeral 1 includes a lathe-type complex machining machine 10 and one robot 30. A setup station 40 is disposed in the vicinity of the robot 30.

  The lathe composite processing machine 10 has a first spindle 110 and a second spindle 120 mounted on the base 12 so as to face the first spindle 110, and a workpiece processed by the first spindle 110 is secondly processed. The spindle 120 is delivered and has a function of processing the next process.

  A milling main shaft 150 is disposed between the first main shaft 110 and the second main shaft 120 on the base 12 of the lathe-type composite processing machine 10. The milling spindle 150 can be equipped with a set-up tool such as a milling rotary tool or a torque wrench in addition to the cutting tool.

  On the base 12 of the lathe-type multi-tasking machine 10, a tool magazine 160 for accommodating a change tool and an automatic tool changer 165 are provided to supply necessary tools to the milling spindle 150.

The robot 30 includes a robot main body 300 and a robot arm 310, and conveys a workpiece, a jig, and the like with a robot hand 320 attached to the tip of the robot arm 310.
The setup station 40 includes a jig place 410 and workpiece pallets 420 and 430, and supplies necessary jigs and workpieces to the lathe-type composite processing machine 10 by the robot 30.

  2 and 3 are explanatory views showing machining steps by the automatic six-face machining system of the present invention.

  The first main spindle 110 of the lathe-type multi-tasking machine 10 is equipped with a universal chuck 50 with a grasping range adjusting function, called a form lock chuck, and grips the workpiece 80.

  The universal chuck 50 with the grasping range adjusting function includes a main body 500 and an opening / closing member 510 that slides in the radial direction with respect to the main body 500. The opening / closing member 510 supports the clamping member 520, and a large number of trace pins 530 are attached to the inside of the clamping member 520. A workpiece 80 to be subjected to automatic six-face machining is, for example, a casting material and has a hole 82.

  The outer surface 800 of the workpiece 80 remains the casting surface and does not have a reference surface to grip. In the universal chuck 50 with the grasping range adjusting function, the trace pin 530 comes into contact with the outer surface 800 of the workpiece 80 with a constant pressure, and grips the workpiece 80 with an appropriate pressure.

  In this state, for example, the outer peripheral surface 810 and the end surface 820 are machined on the end portion of the workpiece 80 using the first main shaft 110 and the milling main shaft 150. Then, a screw hole 830 for attaching the jig plate is also processed in the end surface 820.

  Next, using the robot 30, the jig plate 60 suitable for the workpiece is transported from the jig place 410 of the setup station 40 to the vicinity of the first spindle 110.

  The jig plate 60 includes a main body 600 and a reverse taper portion 610 having a so-called bayonet structure that faces the second main shaft 120 side of the main body 600.

  The robot hand brings the end surface 630 of the jig plate 60 into contact with the processed end surface 830 of the workpiece 80.

  The jig plate 60 has a mounting bolt 620, and the center of the mounting bolt 620 is aligned with a mounting screw hole 830 processed into a workpiece 80. Then, the torque wrench tool 70 provided on the milling spindle is operated to automatically attach the jig plate 60 to the workpiece 80.

  Next, as shown in FIG. 3, after the attachment of the jig plate 60 is completed, the second main spindle 120 moves forward toward the first main spindle, and the workpiece 80 in which the chuck 122 is integrated with the jig plate 60. Grip.

  For the casting surface 800 and the hole 82 of the workpiece 80 chucked on the second spindle 120, the milling spindle performs various processes using various tools.

  In this step, the necessary processing is also performed on the tip surface 850 of the workpiece 80 held by the second spindle 120.

That is, even if the workpiece 80 has a shape formed by six surfaces, the workpiece 80 is gripped by the first spindle, and the workpiece 80 is transferred and gripped by the second spindle. Six surfaces can be processed fully automatically by processing.
The jig plate 60 prepared on the jig place 410 has the same size and structure of the reverse tapered portion 610, and the dimensions and structure of the main body 600 are different so as to correspond to the workpiece. The
The robot attaches the jig plate 60 suitable for the workpiece 80 to the workpiece whose end face 830 is machined by the first spindle, so that the second spindle does not need to be replaced, and different workpieces are processed. can do.

  FIG. 4 is an explanatory view showing a more detailed structure of the universal chuck 50 with a grasping range adjusting function.

  The universal chuck with grasping range adjustment function 50 has an opening / closing member 510 that opens and closes in the radial direction with respect to the main body 500. The clamping member 520 slidably attached to the opening / closing member 510 moves in the arrow A direction by rotating an adjustment bolt 560 provided in the opening / closing member 510 in the arrow R direction.

  By this adjustment, the initial opening degree of the trace pin 530 can be adjusted according to the outer diameter dimension of the workpiece 80.
