Description
Technical field
The present invention relates to a kind of digital controlling plasma groove cutting machine tool, particularly a kind of slew gear of plasma groove cutting machine.
Background technology
Through 10 years of development growths, high-speed, high efficiency, high-quality CNC plasma cutting have been subjected to the generally approval of China's shipbuilding circles.Be accompanied by the rapid increase of China's shipbuilding with steel plate and other metal material cutting quantities, numerical control plasma cutting machine has substituted NC Flame Cutting undisputedly and has occupied leading position at present.Simultaneously, along with the raising of cutting power, cut quality, cutting efficiency, modern industry is also more and more higher for the quality requirement of groove cutting.Initial Chinese steel cut enterprise, for dull and stereotyped groove cutting generally all is to adopt numerical control cutting machine, earlier part is cut down, re-use edge planer, groove cutting machine device people, dolly cutting machine, or the manual grinding mode, through 2 times even 3 processing, just can machine bevel for welding, the manufacturing procedure complexity, labour intensity is big, and the steel waste is serious.These modes can't satisfy the demand that Chinese manufacturing is growing and grow in strength simultaneously.The groove cutting operation of some large shipbuilding enterprises is brought into use the plasma groove cutting machine at present, so that improve cutting efficiency and quality, be follow-up welding service better, but also can save a large amount of factory building resource, human resources, also avoid a large amount of wastes of steel plate resource, thereby in competition, occupied advantage.Present most groove cutting machine adopts slide block or four-bar mechanism more, by moving or the swing of bar of control slide block, cutting torch shape is had a certain degree.Though this groove cutting machine is powerful, but mechanism is too complicated, it is heavy and slow in one's movements that huge structure turns round cutting torch in the course of the work, especially its plasma cutting-torch has many cables and flexible pipe, for guarantee that these cables and flexible pipe do not twine in cutting process, cutting torch just can't really be realized unlimited revolution.And the slew gear technology of plasma groove cutting machine is only grasped by manufacturer of a few family of foreign country at present, domesticly still need import for this series products, from economic angle, introduce the slew gear of this high added value from foreign country, on cost, can increase greatly, be unfavorable for the development of domestic medium-sized and small enterprises.Therefore, the design of plasma groove cutting machine slew gear has great importance for China's development of modern industry.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the present invention to design a kind of compact conformation, motion flexibly, machining accuracy is high, slew gear that can unlimited rotating plasma groove cutting machine.
To achieve these goals, technical scheme of the present invention is as follows: a kind of slew gear of plasma groove cutting machine comprises ball-screw, guide post, link, servomotor A, servo motor B, the swing head, fixed disk, plasma cutting-torch, described ball-screw and guide post are installed in the Y of cutting machine crossbeam on frame, described servomotor A is connected with guide post with ball-screw by link, and be connected with servo motor B by decelerator A, described servo motor B is connected with the swing head by decelerator B, and described plasma cutting-torch is fixed on the swing head by fixed disk; The rotating shaft of described servomotor A and decelerator A on the same axis, the rotating shaft of servo motor B and decelerator B is on same axis, the output shaft of described decelerator A is connected with servo motor B by C type nut, ring flange, the output shaft of described decelerator B is connected with the swing head by C type nut, ring flange, it is vertical mutually that the rotating shaft of described decelerator A and the shaft axis of decelerator B are the space, and the cable of described plasma cutting-torch and flexible pipe are fixed on the upper end of servomotor A.
The cable of plasma cutting-torch of the present invention and flexible pipe pass by the hole of link front end.
Compared with prior art, the present invention has following beneficial effect:
1, since servomotor of the present invention and reducer shaft be positioned on the same axis, reducer shaft directly is connected with driven member, simplified transmission of power between the two, reduced the power loss in the transmittance process, for mechanism's kinematic accuracy at work provides guarantee.Common numerical control cutting machine slew gear is when servomotor at the uniform velocity rotates, and the swing of the space of this slew gear reality is not at the uniform velocity, therefore needs numerical control software to calculate offset control servomotor and then the revolution of realization mechanism.And this time the slew gear of design is because decelerator and driven member directly in succession, have been avoided a large amount of computings of computer, and servomotor uniform rotation in the course of the work helps guaranteeing machining accuracy.
2, because decelerator driving shaft of the present invention adopts " C " type nut to be connected with driven member, replaced traditional key and connected, avoided having influenced the motion of mechanism precision owing to the machining accuracy of key and keyway.
3, because of the present invention when servomotor A rotates, cable and flexible pipe and driven member have successfully solved cable and flexible pipe and have twined problem simultaneously around servomotor A rotation.
4, because two servomotors of the present invention are spatial distribution in mechanism, driving shaft is vertical mutually, and two motors work separately, so motor can not interfere phenomenon at work.
5, because servo motor B of the present invention is a driven member, be again driving link, saved too much connection, simplified space structure, make mechanism compact more.
