摘要： PURPOSE:To make it possible to lubricate an entire unit including a spindle head in the lump by supplying lubricating oil from the turret head side to the spindle head side when supplying the lubricating oil to the turret type cutting unit. CONSTITUTION:A lubricating oil supply path 63 and 71 are made to be led to each other by opening the check valve 67 and 70 provided in a movable ring 55b and fixed ring 55a of a coupling 55 of a cutting unit respectively due to their reengagement. As a result, the lubricating oil supplied from the lubricating oil supply source at the side of a column 10, a part of oil mist, for example, is supplied to the lubricating oil supply path 63 at the side of a gang head 12 through the check valve 67 and 70 with the result that it lubricates the insides of the column 10 and the spindle head 12 positioned at an indexing position not only simultaneously but also in the lump. Thus, the entire unit including the multiple spindle head (gang head 12) can be lubricated in the lump.

摘要： PURPOSE:To improve a seal function to dispense with a sealing work and thereby facilitate automated replacement of gear heads by providing an air supply means for jetting compressed air from the inside of a turret, at the connection between the turret and the respective gear heads. CONSTITUTION:A turret 11 of a turret cutting machine 10 is provided with a gear head 12 on its circumference and a turrent rotating system 13 and a tool drive system 26 therein. An air pipe 40 for introducing compressed air from a compressed air supplier outside the turret 11 and joint 41, in which turret 11 air passage 42, 43, 44 are provided to reach a space 45 difined by the circumference of a column 15. Though cooling water tends to enter in the turret 11 from the gap of the connected part between the gear head and the turret, the compressed air is jetted in the direction C from the gap via the through hole 11a of the turret 11 from the space 45. It is thus possible to prevent the cooling water from entering.

摘要： PURPOSE:To shorten the time required for indexing a turret head by so constituting a clutch mechanism that drive and driven gears can be engaged at once only by sliding movement of a drive shaft at the reengagement of the clutch mechanism. CONSTITUTION:A cutting unit 1 is equipped with a turret head 11 capable of rotation for indexing and plural multiple spindle heads (gang heads) 12. Then, when the drive motor is stopped prior to the completion of the indexing of the head 11, the phases of the crest of a drive gear 25 (the tooth base of a driven gear 59) at the stop position and of the lock pin of a lock plate are controlled at the side of motor control system so that they may be aligned with eacher. And a command for turret rotation for indexing is made to the drive motor. The rotation output of the motor makes the turret head 11 rotate as much indexing angle as required. As a result, the time required for indexing the turret head can be shortened.

摘要： PURPOSE:To clamp two different kinds of workpieces with one workpiece clamping device by utilizing projected portions of the workpieces projecting in one of machining directions, e.g., such as reinforcing ribs and the like. CONSTITUTION:Two pairs of axial direction clamping cylinders 6 and 7 supported by a fixture frame 5 clamp identical workpieces of arbitrary kind between two kinds of cast workpieces 1, one by one, to the fixture frame 5 in the axial direction of the workpiece by gripping their both ends so that orientation of the workpieces is parallel but opposite to each other. In addition, two reference blocks 9 and 10 of the fixture frame 5, which correspond to the clamped cast workpieces, are used for positioning of the workpieces in the peripheral direction through engaging them with the projected portions of the cast workpieces so that these projected portions face to the perpendicular and same direction with respect to the plane containing the workpiece axis. When two workpieces are of different kinds from each other and are to be positioned in the same orientation, the workpieces are positioned in the axial direction so that the projected portions form a line in the tangential direction. After that, the workpieces are clamped by mutual approach of piston rods.

摘要： PURPOSE:To generate a spherical gear with no necessity for using a particular hob, by simultaneously controlling a longitudinal feed and a crossfeed to be combined for a hob and giving the feed to the hob fed along a circular arc locus. CONSTITUTION:A four-axis simultaneous control unit, combining feeds in directions X, Y, gives the feed in a corrected direction Fn to a hob 1. When a gear material W performs one rotation, the hob 1 rotates by the turn of a number of teeth to be generated. The feed in the direction X is synchronously given with the feed in the direction Y so that a gear cutting point is generated along a pitch line of meshing. Accordingly, a spherical gear can be generated with no necessity for using any particular hob only if an NC unit of general purpose type is provided.

摘要： PURPOSE:To make a clutch mechanism compact by making the drive gear provided to a output shaft and the driven gear provided to a input shaft directly engage or disengage according to the slide motion in the axial direction of the output shaft. CONSTITUTION:A drive gear 25 is provided to the output shaft (dirve shaft) 21 at the side of a turret heat 11, and a driven gear 59 to the input shaft (not shown in the drawing) at the side of a multispindle head (gang head) 12. And then, the gears 25 and 59 perform clutch motion being engaged or disengaged each other according to the slide motion of the output shaft 21. This mechanism causes it unnecessary for the output and the input shafts to share the same axis resulting in the reduction of the number of the gears of the gear train on the spindle head. As a result, the whole of the mechanism can be compacted.

摘要： PURPOSE:To reduce the size of and improve cutting rigidity of the captioned unit by providing a turrethead on the slide table side and further providing a motor, used for both indexing the turrethead and driving a spindle, on the opposite side of the slide table. CONSTITUTION:A cutting unit 4 is equipped with a column 10 fixed on a slide table 2, turrethead 11, multiple spindle head 12 and NC motor 14. When a command of indexing rotation is given to the motor 14, its rotational output is transmitted from a train of gears 15, 17, 23, 24 to a drive shaft 21, indexing drive shaft 22, gear reduction mechanism 47, bevel gears 40, 48 in order, and the turrethead 11 is rotated by a predetermined angle. Subsequently, simultaneously with disengagement of a projection part 26 from a slot 37 due to leftward sliding of the shaft 21 by means of a cylinder 38, a drive gear 25 is engaged with a driven gear 59. Then each spindle 58 of a gang mid 12 is driven into rotation by output of the motor 14 and predetermined cutting is performed.
