The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 2, a kind of numerical control axle lathe three hole dials comprise lathe spindle 1, three hole dial body 2, rotary oil cylinder 10, terminal pad 3, driving lever 5, spindle top 6, driving lever positioning disk 4, nipple 8, pull bar 7.Three hole dial bodies 2 are fixedly connected on main shaft 1 end face, be provided with terminal pad 3 in three hole dial body 2 endoporus, be fixedly connected with driving lever positioning disk 4 on terminal pad 3 front end faces, be equipped with at least one driving lever that passes spindle top 65 on the driving lever positioning disk 4, spindle top 6 is fixedlyed connected with three hole dial bodies 2, fixedly connected with pull bar 7 front ends that are arranged in main shaft 1 endoporus in the rear end of terminal pad 3, pull bar 7 rear ends are fastened on the rotary oil cylinder 10 on main shaft 1 rear end face.
Concrete mounting means of the present utility model:
(1) the concavo-convex interface that three hole dial bodies 2 is designed to standard is connected with main shaft 1 front end standard interface.
(2) main shaft 1 rear side is equipped with the rotary oil cylinder 10 that Italian SMW company produces, oil cylinder 10 rear sides are equipped with three noncontacting switches 11 (being that driving lever stretches out, driving lever enters, driving lever puts in place), the sender annulus is installed on the piston rod, and oil cylinder is connected with hydraulic system by oil pipe.
(3) pull bar 7 both sides of main shaft 1 endoporus are equipped with nipple 8, and the terminal pad 3 in the three hole dials of front side is connected with rear side rotary oil cylinder 10, produce excessive winding degree for preventing elongated pull bar 7 in rotary course, so at pull bar 7 middle parts supporting disk 9 is installed.
(4) three hole dial front ends are equipped with spindle top 6, and driving lever 5 and driving lever positioning disk 4 are housed in the dial.
(5) driving lever 5 is contained in the locating hole on the driving lever positioning disk 4; and be connected with workpiece by the mating holes on the spindle top 6; driving lever positioning disk 4 is installed on the terminal pad 3 by screw, damages for preventing axletree workpiece screwed hole, and driving lever 5 front ends are equipped with nylon protective sleeve 12.
During (6) at processing disalignment type, can be according to driving lever 5 positioning disks 4 and the spindle top 6 in the different screwed hole centre-to-centre spacing replacing dials.Unclamp the front side screw, can change easily.
As shown in Figure 3, the concrete method of adjustment of the utility model:
The height of a, adjustment work supporting block 14 guarantees that axletree workpiece place work piece carriage 14 rear center are lower than machine tool chief axis center 0.5mm and get final product.
C, by manipulator with the axletree work piece hoisting on work supporting block 14, and depress the material loading switch simultaneously.
D, tailstock 15 are accepted the material loading signal that puts in place, the oil-feed of barrel of tail stock oil cylinder promotes barrel of tail stock by pressure oil and tailstock centre stretches out, and move to main spindle box 16 directions with the speed of fast moving 5000mm/min, when tailstock centre barrel of tail stock position switch sender during apart from axletree workpiece 15mm, barrel of tail stock slows down speed with 700mm/min slowly near the axletree workpiece, produce bump when avoiding contacting with the axletree workpiece, the top axletree workpiece centre hole promotion axletree workpiece that enters moves along work supporting block 14 straight lines, slowly near three hole dials.
E, when axletree workpiece front end centre bore and spindle top 6 during at a distance of 0.2mm, the barrel of tail stock position switch is sender once more, workpiece and barrel of tail stock stop to move.
After f, main spindle box 16 rear side rotary oil cylinders 10 are accepted the barrel of tail stock stop signal by noncontacting switch 11, promote the inner pull bar 7 of spindle hole and drive three driving levers 5 in the three hole dials by piston rod slowly near the axletree workpiece, drive the low speed rotation of main shaft by main spindle box 16 simultaneously with 1.5r/min, make driving lever 5 and workpiece produce relative motion, thereby can make driving lever 5 rotate to the screwed hole place, and enter smoothly in the workpiece screwed hole.
G, after driving lever 5 has just entered screwed hole, be installed in the driving lever in-position switch sender at rotary oil cylinder 10 places, fast the axletree workpiece is held out against behind tailstock 15 acknowledge(ment) signals, when pressure reaches 2.5MP pressure, the pressure switch sender, meanwhile driving lever 5 continues to advance in the hole under the promotion of rotary oil cylinder 10, and back position switch sender simultaneously puts in place, show the axletree workpiece with held out against and driving lever 5 also to insert in the screwed hole and to put in place, to guarantee axletree clamping workpiece safety.
Full-automatic numerical control axle lathe part work step following (i.e. the actuation cycle of three hole dial clamping workpieces part): the workpiece material loading puts in place → the tailstock F.F. stretches out → the tailstock worker advances slowly near the axletree workpiece and promote workpiece reach → tailstock and stop → main shaft low speed rotation, driving lever stretch out simultaneously → and the tailstock worker advances top tight workpiece → driving lever and stretches out put in place → carry out workpiece calibration, machining.
