Crankshaft of the present utility model is to automatic locating centre device, be provided with cover for seat in the wherein said chuck, the front portion of cover for seat is sleeved on the dead head, the rear threads of cover for seat is connected with core retainer plate, the front portion of core retainer plate is positioned at the cover for seat inboard and is sleeved on the rear portion of dead head, the rear portion of core retainer plate is connected with pull rod screw, and the pull bar oilhole is connected with the gap by the core retainer plate oilhole on the core retainer plate, the dead head oilhole on the dead head.
Crankshaft of the present utility model is to automatic locating centre device, and wherein said oil cylinder checkout gear comprises cylinder body, is provided with piston in cylinder body, piston one side is provided with cylinder body spring, the opposite side of the piston stopper rod of taking over a job, the external end head of piston rod is connected with sensor block, and sensor block and approach switch match.
Crankshaft of the present utility model is to automatic locating centre device, and the section of wherein said fairlead and top suit part is triangle or square or polygon.
Crankshaft of the present utility model is to automatic locating centre device, between wherein said top and fairlead and the dead head radial clearance arranged, the sealing ring that has been provided with of top and dead head.
Crankshaft of the present utility model is to automatic locating centre device, can realize different bent axle axial location, this Finial device milling machine or other axle class machining tool head of a bed and tailstock chuck hub place outside bent axle respectively arrange a cover, when being used for outer milling machine machining crankshafts connecting rod neck or trunnion, realize axially automatically location and the crankshaft length identification of bent axle different modes.
Before the Crankshaft Machining, the machine operation person can select corresponding axial location mode and adjust top group according to bent axle center hole or crankshaft end-face precision or according to technological requirement.
One, different modes axially locates automatically
When 1, adopting the centre bore location of two ends special purpose machine tool processing, removable lower adjusting pad and top spring, top inner termination leans on dead head, axially can not move, at this moment, top is that rigidity is top, and crankshaft end-face does not contact with the chuck locating surface during location, and the bent axle axial dimension is all counted by centre bore.
When 2, adopting a bent axle left side or right side location, two ends top is owing to have top spring and adjusting pad and top end to leave dead head, form the gap, consist of the centre with endlong movement structure, and the spring force in top group of the left and right sides differs twice, and its elastic force difference is guaranteed the top retraction in the chuck of headstock one side, until crankshaft end-face is close to the locating surface of chuck, as changing chuck end face when location of tailstock one end into, the top module position in the left and right sides that then changes the outfit gets final product.For guaranteeing that crankshaft end-face is close to the locating surface of chuck, at the locating surface of chuck gas-detecting device is arranged, this device can detect 0.15mm with interior end clearance.
When 3, adopting other thrust surface location on the main bearing journal, then as long as gas-detecting device is located on the supporting plane of this face (buting iron of location support is arranged in addition).
Two, crankshaft length identification
Crankshaft length identification refers to the soft and hardware function by fully automatic machine, and whether its length of bent axle that automatic identification has been placed on the carriage is corresponding with current procedure, as confirms that difference should stop processing and automatic alarm.Automatically or frequently changing when producing machining crankshafts, can effectively avoid because the mistake bent axle of packing into breaks lathe and cutter, this is i.e. attainable, the crankshaft length recognition function that is different from other method of the less cost of a kind of usefulness.
This function is based upon on the centre with endlong movement group basis, about a cover is respectively arranged, be installed in respectively on the head of a bed and the tailstock chuck, during work, the digital control system control head of a bed and tailstock from the left and right sides with fast speed convergence bent axle, when centre with endlong movement touch central hole of the crankshaft be forced to the compression after, judged fast by the special-purpose software of lathe whether the length of bent axle correct.
Top back comprises that the enclosure space of each oilhole is filled with the low mineral hydraulic oil of viscosity, be connected to one near the dedicated test cylinder body of installing the headstock by pull bar and swivel joint, when headstock driven by servomotor headstock and top top behind bent axle, top being forced to moved backward, at this moment, mineral hydraulic oil in the enclosure space promotes oil cylinder and produces displacement, can accurately detect this displacement and export a switching value signal with electronic proximity switch 12, in time send in the digital control system and digital control system is carried out read in the operation of the current coordinate values of headstock (and tailstock), utilize current headstock coordinate values and the standard coordinate value (bent axle of corresponding different length, to be the standard coordinate value by the coordinate values that actual value locks headstock when being installed for the first time) comparison, can effectively finish the length recognition function of bent axle.
For improving the sensitivity of recognition system, top rear oil pocket area is 2.25 times of dedicated test oil cylinder effective area, and therefore, top compression 1mm detects oil cylinder and stretches out 2.25mm.
The length accuracy of identification of bent axle is ± 2mm.
The characteristics of this cover centre with endlong movement group are simple in structure, easy to operate, reliable and stable, and are flexible strong.
