Angle, the automatic truss of mechanical arm pawl material on equipment lathe put it into fixture, and the positioning cylinder on equipment lathe is by cam
Axis shifts the position for being close to limited screw, fixture Automatic-clamping onto；
(2) end face roughing: the laterally opposed movement of main shaft one of equipment lathe two sides, while both ends clamp camshaft is longitudinal
Mobile to one axis direction of main shaft, dise knife formula cutter front blade carries out milling to camshaft both ends end face, to entire camshaft
After both ends end face carries out milling, a roughing both ends of the surface are completed,
(3) end face finishes: changing longitudinal movement direction, main shaft one continues relative motion, and dise knife formula cutter back side blade is to two
End face fixture Milling Process, after processing is completed, the longitudinal movement of both ends clamp strap moving cam axis return to equipment lathe center, main
Axis one retracts original position backwards；
(4) taper hole drilling is processed: both ends clamp camshaft longitudinally moves to two shaft core position of main shaft, and the brill milling of two sides is double main
Drill bit on the main shaft two of axle box is fed in opposite directions, carries out drilling processing to camshaft step taper hole, main shaft two moves back after processing is completed
It returns in situ；
(5) return: conversion laser detection position confirms that cutting tool state, both ends clamp camshaft retract initial position, fixture
It unclamps, manipulator starts loading and unloading, is machined into new circulation.
Further technical solution, equipment lathe is equipped with rack-and-pinion, opposite sets in the machined structure of camshaft
Two fixtures in rack-and-pinion are set, fixture is V-block self contering structure, and is connect with hydraulic cylinder.
Beneficial effects of the present invention:
1, the present invention is solved by optimizing manufacturing procedure, is arranged by bilateral and is bored the double spindle boxes of milling, and bilateral uses dise knife formula knife
Have simultaneous processing camshaft two sides, and milling is carried out to camshaft using the positive back side of dise knife formula cutter, avoids camshaft
The procedure of processing of overturning not only realizes quick-clamping, Er Qiebao so that procedure of processing reasonable simplicity, saves tool change time
Machining accuracy has been demonstrate,proved, to improve 30% production efficiency, has reduced the consumption to resource.
2, the process equipment that uses has centering precision height, clamping firm stable, simultaneous using modular organization in the present invention
The advantages that capacitive is strong.
3, present invention introduces dise knife formula cutters, have reduced the frequency of use of front sword by optimizing manufacturing procedure, have improved
Service life of cutter improves.
Specific embodiment
Below by non-limiting embodiment, the present invention is further explained, understands the present invention.
The present invention is a kind of processing method of camshaft, using a kind of machined structure of camshaft, machining knot
Structure includes equipment lathe, the double spindle boxes of the brill being arranged at left and right sides of equipment lathe milling, and boring and milling double spindle boxes includes main shaft one:
BT50 milling spindle, two: BT50 drilling main shaft of main shaft；The first main shaft of spindle box is BT50 specification, and facing cutter knife handle directly passes through
Mohs internal taper hole back stay is strained and fixed on the first main shaft top；The second main shaft of spindle box is BT50 specification, centre drill knife handle
For BT50 standard ER circlip knife handle, it is fixed on the second main shaft top.
It bores the main shaft AC servo motor for milling and being installed on the upside of spindle box in double spindle boxes and passes through Imported High-performance synchronous belt
Transmit power to main shaft；The strong stable cutting moment of torque is provided for the cutting of each axis, is set in the machined structure of camshaft
Standby host bed is equipped with rack-and-pinion, two fixtures being oppositely arranged in rack-and-pinion, and fixture is V-block self contering structure, from
Centralizer drives gear upper rack, and connect with hydraulic cylinder.Equipment lathe uses adjustable structure, convenient for workpiece centre
Adjustment.
Specifically includes the following steps:
(1) feeding: camshaft is transmitted to equipment lathe, and the automatic truss of mechanical arm pawl material on equipment lathe puts it into folder
Have, the positioning cylinder on equipment lathe shifts camshaft onto center, fixture Automatic-clamping；
(2) end face roughing: the laterally opposed movement of main shaft one of equipment lathe two sides, while both ends clamp camshaft is longitudinal
Mobile to one axis direction of main shaft, dise knife formula cutter front blade carries out milling to camshaft both ends end face, to entire camshaft
After both ends end face carries out milling, a roughing both ends of the surface are completed,
(3) end face finishes: changing longitudinal movement direction, main shaft one continues relative motion, and dise knife formula cutter back side blade is to two
End face fixture Milling Process, after processing is completed, the longitudinal movement of both ends clamp strap moving cam axis return to equipment lathe center, main
Axis one retracts original position backwards；
(4) taper hole drilling is processed: both ends clamp camshaft longitudinally moves to two shaft core position of main shaft, and the brill milling of two sides is double main
Drill bit on the main shaft two of axle box is fed in opposite directions, carries out drilling processing to camshaft step taper hole, main shaft two moves back after processing is completed
It returns in situ；
(5) return: conversion laser detection position confirms that cutting tool state, both ends clamp camshaft retract initial position, fixture
It unclamps, manipulator starts loading and unloading, is machined into new circulation.
Through testing, camshaft machining period shortens 8 seconds/root, compared with original processing method, has the advantage that original
Beginning processing method is only repeated by manufacturing procedure, uses front blade, building up by welding is changed to indulge in processing method of the present invention
To moving back and forth, benefit not only is subject to back side blade using the different knife faces of dise knife formula cutter for different movement routines
With improving work efficiency to reduce the frequency of use of front sword.
