摘要： PURPOSE:To provide possibility of rotating a tap in the regular and reverse directions when female threads are machined and are drawn out, respectively, without changing-over of the motor rotating direction. CONSTITUTION:A tapping device is equipped with a drive screw shaft 16 provided with a steep gradient spiral groove, a ball nut 22 which is engaged by the spiral groove and rotates the screw shaft 16 while moving along the screw shaft 16, and a crank disc 27 to be rotated by a motor 29. The arrangement further includes a rod 24 to rotate the screw shaft 16 in the regular and the reverse direction by recipocating the ball nut 22 with rotation of the disc 27 upon coupling them together, and transmitting means 18, 31, 32, 33, 34, 37 which transmit the rotation of the screw shaft 16 to a tap rotating shaft 18 fited with a tap 41.

摘要： PURPOSE:To prevent a tool holder from dropping and also eliminate the accurate adjustment of timing between the lifting of a lifting shaft in engaging and disengaging of the tool holder and the movement of a tool exchange arm of an automatic tool exchange device. CONSTITUTION:Because a lifting tube 25 is energized upward by a spring 26, even if a holding section 4 of a tool holder 1 is held by a chuck 15 and a lifting shaft 28 whereby the lifting tube 25 is lifted is lowered, it does not lower and, because the chuck 15 keeps holding the tool holder 1, the tool holder 1 will not lower. After that, if the tool holder 1 is lowered against the energizing force of the spring 26, the lifting tube 25 and chuck 15 will lower and, when the chuck 15 arrives at an opening position, the chuck 15 will open and the tool holder 1 will be disengaged.

摘要： PURPOSE:To maintain the lengths of a follower shaft and an engaging clutch in axial direction sufficiently, and also downsize an entire device. CONSTITUTION:Rotation spindles 6 in a turret head 4, a follower shaft 11 in a turret stand 1, and an engaging clutch 7 are arranged on an axis L2 which is in parallel with a radial line L1 intersecting at right angle with a turret head axis 3 and eccentric slightly to the side. By this, the lengths of the follower shaft 11 and engaging clutch 7 in axial direction can be maintained sufficiently, and the rotation spindles 6 are brought closely into the turret head shaft 3 to reduce the outer diameter of the turret head 4 and downsize the entire device.

摘要： PURPOSE:To correct a suction position after an IC element is sucked by arranging a positioning means, centripetally, concentrated and separated along with vertical movement of a sucking pipe, along the periphery of the tip part of a suction pipe to suck the IC element to its tip. CONSTITUTION:A suction pipe 18 rises together with an elevating cylinder 8 and a coupling cylinder 15, and rising is stopped through contact of an upper end 8B of the elevating cylinder 8 with an outer cylinder 3. However a pipe shaft 11 continues its rising and a rotation cylinder 5 is rotated through the passage of a lock pin 13, elevated togetherwith the pipe shaft 11, through a bent part 6c of a bent slot 6 from below. Press pieces 25 are simultaneously moved in a centripetal direction, and an IC element being in an eccentric state and displaced in a direction is corrected. After a centering finger is moved to a desired position, by bringing the interior of the suction pipe 18 into a normal pressure state after the suction pipe 18 is lowered, the IC element is placed in correct attitude in a correct position.

摘要： PURPOSE:To improve machining accuracy by preventing inaccuracy of machining, by sensing a position on an axial line of a master spindle of a tool by use of a positioning lever and a sensor and numerically controlling the tool after accurately indexing a machining start reference position. CONSTITUTION:A tool B mounted on a driving unit A may have an inaccurate relative vertical position with respect to the driving unit A due to its dimensional error, a dimensional error at an engaging position 3 or the like when the tool B is mounted or wear etc. To solve the problem, there are provided a positioning lever 14 which abuts against an upper end of a master spindle 39 for holding a tap 45 and vertically moves together with it and a sensor 17 for sensing that it is at a machining start position in an axial direction. After an automatic tapping machine starts, the reference position sensor 17 senses the upper end of the lowering positioning lever 14 and the automatic tapping machine is numerically controlled when a rotation reference position sensor 9 senses a projecting portion 8a of a positioning plate 8.

摘要： PURPOSE:To make it possible to quickly select a tool required for use out of various kinds of loaded tools, by rotating a spindle head utilizing a motor- driven cam-drive mechanism. CONSTITUTION:As a geared motor starts rotation, a cam axis 24 rotates, the clutch axis 15 is pushed back firstly by the first cam follower 33, and the clutch 12 is cut off. Then, a spindle head 7 is raised by the third cam follower 42, and the coupling 3 is cut off. Thereafter, the spindle head 7 is rotated coupled with each spindle 11 by the second cam follower 40. Then, the spindle head 7 is lowered by the third cam follower 42 and is connected with the coupling 3. Following this, the clutch 12 is connected there to by the first cam follower 33, a spindle adjacent to a spindle 11' is faced forward and connected with the clutch shaft 15. With repetition of these operations, a required tool is quickly selected out of loaded tools.

摘要： PURPOSE:To enable easy measurement of unbalance at a high accuracy without damage to differential gears, by bringing a drive disc driven to rotate in friction contact with one of right and left wheels while the wheels are rotated with the engine. CONSTITUTION:An onboard balancer 24 drives a truncated pyramid drive disc 4 with a motor carried. A signal voltage detected with a pickup 3 which is attached to a measuring stand 23 to left wheels 2 is inputted into a microcomputer 8 through an amplification circuit 5, a waveform shaping filter 6, A/D converter 7 and zero-cross detection circuit 18 and the detection signals of sensors 9 and 9 for detection of rotation is inputted thereinto 8 through a waveform shaping circuit 10. Moreover, a drive disc 4 is brought into friction contact with one of vehicle wheels 1a and 1b while the wheels are rotated with the engine 21. Thus, the difference in the rotational speed between the vehicle wheels 1a and 1b in the rotation with the engine 21 and the drive disc 4 to keep the revolutions almost equal between the right and left wheels to determine the amount of unbalance and circumferential position of the vehicle wheels 1a and 1b.
