Embodiment 1
[0027] see Figure 1-2 , a forging piston four-station drilling fixture, including a rotary table and a backing plate 2, four precision centering vises 3 are fixedly arranged on the upper surface of the backing plate 2, and four precision centering vises 3 are fixed on the backing plate The upper surface of 2 is arranged in a line and aligned in the X direction. The center distances of the left one and left three precision centering vises 3, the left two and left four precision centering vises 3 are all consistent with the center distances of the double spindles of the machining center. The two ends of the upper surface of each precision centering vise 3 are symmetrically fixed with two claws 5, and the upper part of the claws 5 is equipped with an elastic plunger 6 that protrudes on both sides to tighten the workpiece, and the elastic plunger 6 is set. It is convenient to fix the workpiece, making the fixation convenient and quick. The top of the claw 5 is welded and fixed ...
Embodiment 2
[0030] On the basis of Embodiment 1, the index plate 9 and the tailstock 10 are respectively fixed on the base base 12 through the riser block 11 , thereby maintaining the integrity of the whole device.
[0031] Working principle and processing method of the present invention:
[0032] Assembly: Assemble the special fixtures and tools of the type required for this processing, and calibrate the accuracy of the clamping position, and the double-spindle machine tool is ready to start;
[0033] Feeding: Put the four piston workpieces into the jaws 5 of the special fixture in turn by manual or mechanical hands, and the elastic plunger 6 on the upper part of the jaws 5 is automatically tightened, and the jaws 5 and elastic plunger 6 are waiting for the inside of the hole to be drilled. Peripheral positioning, the support column 7 on the top of the jaw 5 is positioned on the inner top surface of the workpiece;
[0034] Clamping: After the workpiece is placed, the two oil cylinders 1...
