Description
Technical field
The utility model relates to the electric spark linear cutting machine technical field, specifically a kind of dynamo-electric consubstantiality WEDM wire storage tube.
Background technology
The storage silk of reciprocating type high-speed wire electrical discharge machine tool (abbreviation lathe), thread delivering machine structure (abbreviation wire storage tube) are one of critical components that influences machine tool mechanical performance and processing technology index, lathe when the spark discharge cutting processing, require 400～800M molybdenum filament (electrode) that wire storage tube stores with the linear velocity of 12～20M/S continuously, back and forth, accurately, operation reposefully.Under the operating mode of like this high request, wire storage tube mechanism has all been proposed strict requirement from being designed into manufacturing: 1. operated motor should have characteristics such as little quality, big torque, high accuracy, high rotating speed and bear the high overload ability of frequent commutation; 2. the wire storage tube assembly should possess good dynamic balancing index and minimum quality; 3. motor should satisfy high concentricity requirement with being connected of wire storage tube; 4. unique machining benchmark (mechanical zero) can adopt precision processing machine to make high-precision wire storage tube; 5. minimum assembling link is avoided the interference of human factor to the machining accuracy index.
No matter the wire storage tube mechanism (being called for short old wire storage tube) that uses makes each link from being designed at present, all can't satisfy above-mentioned requirements, now be illustrated according to shown in Figure 2: run motor (AC asynchronous motor or brush direct current motor) (1) is fastenedly connected by seam on its end face (2) and wire storage tube ring flange (3), is packed on the wire storage tube support (4) again.Run motor (1) axle head is by shaft coupling (5) and wire storage tube axle (6) sliding connection, and wire storage tube (7) is installed on the support (4) by bearing (8), and support (4) is contained on the slide plate (10) in the base rail groove.Travelling gear (9) on the wire storage tube axle (6) meshes by cog belt with the turn-screw gear, thereby realizes the reciprocating operation function of wire storage tube.The problem that old wire storage tube exists is: 1. AC asynchronous motor or brush direct current motor are big quality, low overload, slow speed motor, can't satisfy the requirement of lathe to high rotating speed, high overload, little quality and the frequent commutation continuous operation of wire storage tube proposition; 2. the running accuracy of operation of electrically driven arbor output, the accuracy of manufacture and assembly precision by motor guarantees on the one hand, relies on the processing and manufacturing precision technic index of bearing chamber processing and manufacturing precision technic index, two end cap centre bore and cylindrical concentricity processing and manufacturing precision technic index, seam concentricity processing and manufacturing precision technic index and the motor reel of motor two end cap that is:; Processing and manufacturing precision technic index and assembly precision index by motor seam and wire storage tube ring flange and wire storage tube bracket end face and bottom surface fixed bit guarantees on the other hand.According to the machining principle as can be known, the part or the parts of different mechanical zero processing need be assembled by pincers worker according to technological requirement when combination, have just produced the tolerance stack-ups phenomenon, and accuracy of manufacture index is descended.The part of combination is many more, and dimension chain is long more, and precision is poor more, this phenomenon can't be eliminated by precision processing machine disposable (single zero-bit), more can't eliminate, and this phenomenon disperses with the technology difference of pincers worker, produce general individual manufacturing variation by pincers worker assembling; 3. motor was finished with being connected by assembling of wire storage tube, had the problems referred to above equally; 4. the wire storage tube of diameter very big (Φ 160mm), when moving back and forth at a high speed, the torsional moment that produces acts on the wire storage tube axle rigidly, and be delivered on the motor reel by shaft coupling, the arm of force is reversed in formation, this arm of force amplifies according to the Abbe effect according to operating distance and forms the twisting vibration phenomenon, causes the early stage mechanical fatigue of each, and damage of bearings and off-axis fault occur.
Summary of the invention
The purpose of this utility model is exactly a kind of dynamo-electric consubstantiality WEDM wire storage tube that designs for addressing the above problem, this mechanism adopts external-rotor-type direct current brushless motor, and unofficial biography is configured to the wire electrode tube, make motor have the function of storage silk and running consubstantiality.
The utility model is achieved in that dynamo-electric consubstantiality WEDM wire storage tube is made up of motor stator, stator axis, wire storage tube support, motor rotor, bearing, wiring and travelling gear, motor stator is fixedlyed connected with stator axis and is packed on the wire storage tube support, and the stator axis end is provided with cable hole; Motor rotor is connected on the stator axis by bearing, and rotor one end is connected with travelling gear, and wiring is connected motor stator by the dead eye of the rotor other end with the stator axis cable hole.
The utility model facility have following characteristics:
1. the stator axis that supports motor stator is exactly the mechanical zero of wire storage tube, multipart processing technology is a benchmark with this zero-bit all, adopts machining to finish, and its precision relies on the precision of processing equipment to guarantee, thereby make the high conformity of machining accuracy, it is big to promote leeway.Moreover, assembly work only takes place once, promptly only produce the rigging error of bearing and rotor bearing position, and this error can be set and control to minimum by selecting the high-quality bearing for use and regulating build-up tolerance, also can by to assemble back wire storage tube surface accuracy again grinding eliminate.Its three, storage silk and running gear flexibly connect with the motor stator axle, staring torque and commutation torsional interaction as long as make bearing obtain good lubricated and cooling, start and the destructive power of the generation that commutates can be reduced to minimum on the rolling member bearing.The commutation moment of torsion can make the commutation running of motor produce hysteresis phenomenon and reduce the motor dynamic response and the energy loss-rate, but can the mechanical performance and the processing performance of lathe not had a negative impact.Therefore, can put it briefly, " cylindrical shell " structure of optimization has formed best process for machining and manufacturing, has selected the high-precision motor of high-quality for use in addition, has also just made the high accuracy wire storage tube of high-quality.
2. employing summation watt rating ratio is big, efficiency is high, high-power, the motor of little quality, and this DC Brushless Motor with high rotating speed high overload coefficient can satisfy the high-tech requirement of lathe to wire storage tube.
3. wire storage tube has high performance price ratio, has cutting down the consumption of energy and reduces the characteristics of material consumption.
In a word, wire storage tube can be applied according to its technical advantage fully, thereby makes the upgrading of electric spark linear cutting machine storage silk works.
