Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described;
Fig. 1 is the structural representation of the positional cylinder of the present invention;
Fig. 2 is the one-piece construction schematic diagram of the drum assembly positioned of the positional cylinder adopting the present invention;
Wherein, 1. drum, 2. positional cylinder, 2-1. piston rod, 2-2. piston, 2-3. step, 2-4. position limiting convex ring, 2-5. transmits dish, and 2-6. transmits switch, 3-1. servomotor, 3-2. speed reduction unit, and 3-3. is synchronously with, the synchronous belt wheel of 3-4..
Embodiment
As shown in Figure 1, the piston 2-2 that positional cylinder 2 comprises cylinder body, piston rod 2-1 and is arranged in cylinder body, cylinder body is arranged in frame by flange, piston rod 2-1 in cylinder body is divided into thick portion and thin portion, the step 2-3 that piston rod 2-1 moves is promoted to drum 1 side under the joining place in thick portion and thin portion is formed in hydraulic efficiency oil effect, piston 2-2 is sleeved on the thick portion of piston rod 2-1 slidably, have the limiting component preventing piston 2-2 landing to thin portion in the thick portion of piston rod 2-1, limiting component is specially position limiting convex ring 2-4. Positional cylinder 2 has detection piston rod 2-1 and whether moves to the insertion position of pilot hole and whether piston rod 2-1 moves to the detection device of the position extracting pilot hole. Detection device comprises and transmits dish 2-5 and detection transmits two of dish 2-5 position and transmits switch 2-6, transmit switch 2-6 and adopt proximity switch, one end away from drum 1 of piston rod 2-1 passes cylinder body, transmits dish 2-5 and is arranged on one end away from drum 1 of piston rod 2-1.
As shown in Figure 2, a kind of drum assembly, comprises the drum 1, calibration driving mechanism, locating mechanism and the drum that are arranged in frame and clamps mechanism, and drum 1 is arranged on frame by drum axle, drum 1 has multiple station, each station has workholder. Calibration driving mechanism and locating mechanism are positioned at the same side of drum 1, and drum clamps another side that mechanism is positioned at drum 1. Frame comprises the left and right sidesing wall plate of drum both sides, be positioned at left and right sidesing wall plate top connection left and right sidesing wall plate determine beam. Locating mechanism comprises the positional cylinder 2 being arranged in frame and the pilot hole of drum 1 side, when drum 1 rotates to station position, the piston rod 2-1 of positional cylinder 2 stretches out the pilot hole of insertion drum 1 side, drum 1 is positioned, pilot hole is taper hole, and the head end of the insertion pilot hole of piston rod 2-1 is the cone head coordinated with taper hole.
Because the piston 2-2 of positional cylinder 2 and piston rod 2-1 is split type, and piston 2-2 can move freely on piston rod 2-1. When positional cylinder 2 is located, hydraulic pressure pressure oil enters in cylinder body from right cavity of cylinder, the pressure of hydraulic pressure pressure oil acts on piston 2-2 and piston rod 2-1, piston 2-2 is moved to drum 1 side, piston rod 2-1 is also promoted by hydraulic pressure pressure oil and moves to drum 1 side simultaneously, until the cone head insertion pilot hole of piston rod 2-1, now, scantlings of the structure, to be ensured that the distance piston 2-2 of the position limiting convex ring 2-4 on piston rod 2-1 has certain distance. During the cone head insertion pilot hole of piston rod 2-1, its reactive force also be can't help piston 2-2 and provided, but provides by the step 2-3 on piston rod 2-1, due to step 2-3 size not quite, be therefore supplied to the latch power of piston rod 2-1 and not very big, this is just meeting service requirements; And contrary, when pulling pin, promote piston 2-2 to be moved to the left by the hydraulic pressure pressure oil entering the left chamber of oil cylinder, when driving piston rod 2-1 to be moved to the left after the position limiting convex ring 2-4 meeting piston rod 2-1, complete action of pulling pin.
When after the cone head insertion pilot hole of piston rod 2-1, owing to producing blocking force so that pull pin and become difficulty, and piston 2-2 is to producing certain impulse force when moving right and meet position limiting convex ring 2-4, contributes to extracting piston rod 2-1. The unique distinction of this this positional cylinder 2 just.
Calibration driving mechanism drives drum 1 to rotate to each station by calibration requirement, calibration driving mechanism comprises servomotor 3-1, speed reduction unit 3-2, synchronous band 3-3 and synchronous belt wheel 3-4, synchronous belt wheel 3-4 is arranged on the output shaft of drum axle and speed reduction unit 3-2, driven by synchronous band 3-3 between synchronous belt wheel 3-4 belt wheel 3-4 synchronous with on drum axle on speed reduction unit 3-2 and connect, the main shaft of servomotor 3-1 directly inserts the input terminus of speed reduction unit 3-2, and servomotor 3-1 is rotated by speed reduction unit 3-2 drive drum wheel shaft.
For the drum assembly of 8 stations, its action process is as follows:
1, lathe digital control system sends drum and starts to turn round instruction, and servomotor 3-1 rotates, and drives the speed reduction unit 3-2 of a gapless, the reduction ratio i=250 of this speed reduction unit.
2, output terminal at speed reduction unit 3-2 has installed a synchronous belt wheel 3-4, and this synchronous belt wheel 3-4 drives synchronous band, transmits motion to a synchronous belt wheel 3-4 of drum axle head, and modulus, the number of teeth of two synchronous belt wheel 3-4 are completely identical, it is achieved 1:1 transmission.
3, the synchronous belt wheel 3-4 of drum end just drives drum 1 to realize revolution, and when drum 1 turns round a station (during 8 station, design revolution angle is 22.5 ��), revolution transmits switch and sends signal.
4, after system acceptance to the signal sent, namely sending the action that positional cylinder 2 is located, be arranged in three positional cylinder 2 actions immediately of the right wallboard of drum 1, complete location, the proximity switch of the detection device of positional cylinder 2 has also sent signal.
5, after system acceptance to this signal, sending drum clamping instruction, clamping cylinder 4-3 action immediately, drive locking screw cover 4-1 to rotate, drum 1 clamps immediately, and clamping switch sends the signal clamped.
