Description
Technical field
The utility model relates to a kind of lathe auxiliary equipment, more precisely a kind of work tank that is applicable to large-scale spark-erosion machine tool.
Background technology
At present, on market, large-scale spark-erosion machine tool still adopts two ox head structures, that is to say that electric spark main shaft is single column cantilever support.Along with improving constantly of EDM Technology level, the stroke of spark-erosion machine tool constantly increases, and traditional two ox head structures are difficult to meet the requirement of processing characteristics, thereby the conventional planer type structure of Large Cutting lathe is introduced into spark-erosion machine tool.
Due to the whole process of spark machined, be at tool-electrode and working solution repeatedly on-off electricity in the situation that, the little by little allowance of ablation workpiece.This just requires workpiece to be immersed in working solution, to form current loop, reaches the object of energising processing.Under normal circumstances, spark-erosion sinking lathe all can have corresponding work tank to match with it.For workpiece loading and unloading, and in process, observe processing situation, liquid bath must arrange the door that facilitates opening and closing, and it is the same that the liquid bath of this point and traditional cattle-head spark-erosion machine tool requires.The door of the work tank of the large-scale spark-erosion machine tool of tradition is the lifting mechanism with parallelogram connection-rod and hydraulic system composition.This liquid bath door is because size is little, therefore can accomplish that mechanism operates steadily, and has good seal, is subject to the extensive approval in market and is used always.
For heavy duty machine tools, introduce gantry structure must considering of designer often, but because the moving post at gantry just in time in the operating surface direction of lathe, the opening and closing action of door with move post and likely cause interference.Be exactly will reserve sizable space between door and moving post to the solution of this problem, this makes again designer feel to hesitate to the large-scale spark-erosion machine tool of gantry structure.If the structural design of liquid bath door can be obtained compactly, therefore do not affect the design of the moving post in gantry simultaneously, planer type structure will impel the more and more large-scale change of spark-erosion machine tool.
The feature of large-scale spark-erosion machine tool is that the longitudinal length size of lathe is increasing, the length of liquid bath door is also more and more longer, in order to guarantee enough rigidity, the weight of heavy duty machine tools work tank door is very large, and parallelogram connection-rod and the oil cylinder lifting mechanism of continuing to use traditional machine tool can not the stable liquid bath doors that promotes weight like this.
Summary of the invention
The purpose of this utility model is, parallelogram connection-rod and the oil cylinder lifting mechanism of continuing to use traditional two ox head spark-erosion machine tool work tanks for large-scale spark-erosion machine tool can not stably promote greater weight liquid bath door, and a kind of liquid bath door of the work tank with automatic open close function that is suitable for spark-erosion machine tool design feature is provided.
The technical solution that realizes goal of the invention of the present utility model is as follows:
The work tank of large-scale spark-erosion machine tool comprises liquid bath body, the liquid bath door of liquid bath body forms with Xiamen by visiting, the bottom of visiting and the upper end of Xiamen are connected through the hinge, it is hinged that the bottom of Xiamen is provided with the base of hinge and lathe, the both ends, left and right of visiting connect with hydraulic drive mechanism, and realize the opening and closing of liquid bath door by hydraulic drive mechanism.Described hydraulic drive mechanism is made up of hydraulic cylinder, driving lever and follower lever, one end of the driving shaft of hydraulic cylinder and driving lever and follower lever is connected through the hinge, the other end of driving lever is connected with the base of lathe by hinge, and the other end of follower lever is connected with the roller that the both ends, left and right of visiting are provided with by hinge.
The two ends, left and right of above-described liquid bath body are provided with guide plate, and the medial surface of guide plate is provided with guide channel, and the both ends, left and right of visiting are provided with roller and are flexibly connected with guide channel, visit and are subject to the constraint of guide channel, thereby make liquid bath door by the orbiting motion of setting.
Above-described guide channel shape is linear or shaped form.
Above-described driving lever and follower lever are on same straight line in the time that liquid bath door is opened completely, thereby realize self-locking, alleviate the load of hydraulic cylinder.
The utility model is provided with after liquid bath door is closed for compressing the hydraulic locking apparatus of upper-lower door, hydraulic locking apparatus is made up of mechanical lock, oscillating oil cylinder and oil cylinder fixing base, wherein mechanical lock is installed in the two ends of upper-lower door, oscillating oil cylinder is installed in position corresponding with mechanical lock on liquid bath body by oil cylinder fixing base, the tapered end of oscillating oil cylinder, by stretching out, swinging, is realized locking and the sealing of liquid bath door in the cavity of insertion mechanical lock.
When liquid bath door of the present utility model is opened, inwardly fold and be in horizontal level.
The rear portion of liquid bath body of the present utility model is provided with assistant supporting mechanism, and this mechanism is fixedly arranged on the fixed part of lathe.
Above-described liquid bath body is metal material and makes by welding procedure.
Operation principle of the present utility model is that the design of liquid bath door is become collapsible, hinged by hinge and lathe, can be by a part of weight transmitting of liquid bath door to bed piece, the weight that is equivalent to liquid bath door half is born by bed piece, therefore can reach the object that reduces door driving load.The door of long size can be considered flexible body substantially, when limit be wherein hinged axle fixing after, will improve to a certain extent the rigidity of liquid bath door, improve the stability of liquid bath door opening and closing work.
Liquid bath door design is become collapsible, can also better solve the stress deformation problem of door, but Men Kai
While closing action, take up space large, the liquid bath door turning up is also absolutely unsafe for operating personnel.The design of liquid bath door is become to folding structure, and the opening and closing operation of door is inwardly to open, and processing safety greatly improves.
