Description
Technical field
The present invention relates to a kind of Finial device, particularly a kind of Crankshaft is to automatic locating centre device.
Background technology
When Crankshaft Machining, all there is top support at its two ends, and the top of existing main spindle box one end in the axial direction can not according to axial force automatic adjusting position, form rigid support, supporting way is single, accurately can not identify the length of bent axle when clamping bent axle, makes troubles to coaxial processing.
Summary of the invention
The object of this invention is to provide a kind of top can to Crankshaft to location automatically, coordinate can to identify when the automatic radial location of chuck, clamping that crankshaft length, structure are simple voluntarily, the reliable Crankshaft of flexible movements to automatic locating centre device, overcome the deficiencies in the prior art.
Crankshaft of the present invention is to automatic locating centre device, comprise main spindle box, main shaft, pull bar, chuck, top, dead head is had at chuck internal fixtion, top rear portion is inserted dead head endoporus and top spring is housed, top spring one end leans on top, the other end leans on the adjusting pad bottom dead head endoporus, gap is had between top and adjusting pad, top front portion is set with fairlead, fairlead is fixedly connected with dead head, described gap is connected with the pull bar oilhole at pull bar center, pull bar oilhole is connected with oil cylinder checkout gear by swivel joint, match with oil cylinder checkout gear and have sensing element.
Crankshaft of the present invention is to automatic locating centre device, cover for seat is provided with in wherein said chuck, the front portion of cover for seat is sleeved on dead head, the rear threads of cover for seat is connected with core retainer plate, the front portion of core retainer plate to be positioned at inside cover for seat and to be sleeved on the rear portion of dead head, the rear portion of core retainer plate is connected with pull rod screw, and pull bar oilhole is connected with gap by the core retainer plate oilhole on core retainer plate, the dead head oilhole on dead head.
Crankshaft of the present invention is to automatic locating centre device, and wherein said oil cylinder checkout gear comprises cylinder body, in cylinder body, be provided with piston, piston side is provided with cylinder body spring, the opposite side of piston is taken over a job stopper rod, and the external end head of piston rod is connected with sensor block, and sensor block and proximity switch match.
Crankshaft of the present invention 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 invention is to automatic locating centre device, wherein said top and have radial clearance between fairlead and dead head, is provided with sealing ring between top and dead head.
Crankshaft of the present invention is to automatic locating centre device, different bent axle axial location can be realized, this Finial device respectively arranges a set of at the outer milling machine of bent axle or other axle class machining tool head of a bed and tailstock chuck center, during for outer milling machine machining crankshafts connecting rod neck or trunnion, realize axially location and the crankshaft length identification automatically of bent axle different modes.
Before Crankshaft Machining, machine operation person or can select corresponding axial location mode according to technological requirement and adjust top group according to bent axle center hole or crankshaft end-face precision.
One, the axially automatic location of different modes
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, now, top is that rigidity is top, and during location, crankshaft end-face does not contact with chuck locating surface, and bent axle axial dimension is all counted by centre bore.
When 2, adopting bent axle left or right end face location, two ends top owing to having top spring and adjusting pad and dead head is left in top end, form gap, form centre with endlong movement structure, and the spring force difference twice in top group of left and right, its elastic force difference guarantees the top retraction in the chuck of headstock side, until crankshaft end-face is close to the locating surface of chuck, when chuck end face as changed tailstock one end into is located, then change the outfit the top module position in left and right.For guaranteeing that crankshaft end-face is close to the locating surface of chuck, the locating surface of chuck has gas-detecting device, and this device can detect the end clearance within 0.15mm.
When 3, adopting other thrust surface location on main bearing journal, (separately there is location buting iron support) as long as be then located at by gas-detecting device on the supporting plane in this face.
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 bracket is corresponding with current procedure, and as confirmed, difference should stop processing and automatic alarm.When automatically or frequently changing product machining crankshafts, effectively can avoid because mistake loads bent axle and break lathe and cutter, this is the less cost of a kind of use and attainable, to be different from other method crankshaft length recognition function.
This function is based upon on centre with endlong movement group basis, left and right respectively has a set of, be arranged in the head of a bed and tailstock chuck respectively, during work, digital control system controls the 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 compression after, judge that whether the length of bent axle correct fast by the special-purpose software of lathe.
The top enclosure space comprising each oilhole is below filled with the lower mineral hydraulic oil of viscosity, be connected on a dedicated test cylinder body installed near headstock by pull bar and swivel joint, when after headstock driven by servomotor headstock and top top to bent axle, top being forced to is moved backward, now, mineral hydraulic oil in enclosure space promotes oil cylinder and produces displacement, this displacement can accurately be detected with electronic proximity switch 12 and export an on-off model, digital control system is made to perform the operation of reading in headstock (and tailstock) current coordinate values in timely feeding digital control system, utilize current headstock coordinate values and the standard coordinate value (bent axle of corresponding different length, the coordinate values that first time will lock headstock by actual value when being installed is standard coordinate value) comparison, effectively can complete 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 stretch out 2.25mm.
The length accuracy of identification of bent axle is ± 2mm.
The feature of this cover centre with endlong movement group is that structure is simple, easy to operate, reliable and stable, flexible strong.
