Abstract
The utility model discloses a counterweight mechanism of a electric spark former spindle driven by a linear motor, which comprises a tool electrode, the linear motor, a linear guide rail, a motor connecting rod, a lever, a hydraulic cylinder connecting rod, a hydraulic cylinder and a lever carriage; by regulating the oil pressure and the speed of the hydraulic cylinder, the counterweight mechanism of the electric spark former spindle driven by the linear motor precisely counterweighs the gravity of a spindle head in real time under the transmission of leverage, and the uniform deployment facilitates the guarantee of the rigidity and deformation uniformity of a machine tool.
Description
Technical field
The utility model relates to a kind of electric spark shaping mill, relates in particular to a kind of counter weight construction of electric spark shaping mill main shaft of linear electric motors driving.
Background technology
The electric spark main shaft is one of vitals in the electric spark shaping mill, and it is that Electric Discharge Machining guarantees efficiently that electric spark main shaft linear electric motors drive.The linear electric motors counter weight construction that uses both at home and abroad mainly adopts balancing weight to realize at present, and mainly there is following shortcoming in it: when the electric spark main shaft is realized the overload cutter lifting, because the hysteresis quality that balancing weight quickens causes main shaft cutter lifting speed to reduce, influence working (machining) efficiency.Secondly, when the main axle structure deadweight changes, can't carry out counterweight adjustment timely quick and precisely, influence the integral rigidity of lathe and the even distribution of structure gravity, the impact when increasing the lathe operation.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, the electric spark shaping mill main shaft balance weight mechanism that provides a kind of linear electric motors to drive.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the balance weight mechanism of the electric spark shaping mill main shaft that a kind of linear electric motors drive, and it comprises: tool-electrode, linear electric motors, line slideway, motor connecting rod, lever, hydraulic cylinder connecting rod, hydraulic cylinder, lever bracing frame; Wherein, described linear electric motors, motor connecting rod, lever, hydraulic cylinder connecting rod, hydraulic cylinder and lever bracing frame are formed a lever rigid balancing mechanism by hinge; Hydraulic cylinder connecting rod one end stretches into hydraulic cylinder, the other end links to each other with lever by hinge, and the lever other end links to each other with the motor connecting rod by hinge, and lever is supported by the lever bracing frame by hinge, linear electric motors link to each other with the motor connecting rod, and tool-electrode is fixed on linear electric motors secondary.
The beneficial effects of the utility model are, by the oil pressure pressure of hydraulic cylinder and the adjusting of speed, under the transmission of lever force, the gravity of main tapping are carried out in real time accurately counterweight, and configuration helps evenly guaranteeing that the rigidity of lathe and deformation are even.
Description of drawings
Fig. 1 is the schematic diagram of the electric spark shaping mill main shaft balance weight mechanism of the utility model linear electric motors driving;
Among the figure, tool-electrode 1, linear electric motors 2, line slideway 3, main shaft 4, motor connecting rod 5, hinge 6, lever 7, hydraulic cylinder connecting rod 8, hydraulic cylinder 9, base 10, column 11, lever bracing frame 12, crossbeam 13 and oil groove 14.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be described in further detail:
The balance weight mechanism of the electric spark shaping mill main shaft that the utility model linear electric motors drive comprises: tool-electrode 1, linear electric motors 2, line slideway 3, motor connecting rod 5, hinge 6, lever 7, hydraulic cylinder connecting rod 8, hydraulic cylinder 9, lever bracing frame 12.
As shown in Figure 1, tool-electrode 1 is installed on linear electric motors 2 secondary; Line slideway 3 vertically is installed in the front end face of electric spark shaping mill main shaft 4, and during work, linear electric motors 2 are done moving of vertical direction along line slideway 3; Motor connecting rod 5 links to each other with the leading section of lever 7 by hinge 6, and linear electric motors 2 are installed in the lower end of motor connecting rod 5; Hydraulic cylinder 9 is fixed on the rear end face of column 11; Hydraulic cylinder connecting rod 8 is piston rods of hydraulic cylinder 9, links to each other with lever 7 by hinge 6; Lever 7 is installed in column 11 upper surfaces of electric spark shaping mill by lever bracing frame 12.
During work, form a lever rigid balancing mechanism by hydraulic cylinder 9, hydraulic cylinder connecting rod 8, lever 7, motor connecting rod 5, linear electric motors 2 and several hinges 6.By the oil pressure pressure of hydraulic cylinder 9 and the adjusting of speed, under the transmission of lever force, the gravity of main tapping is carried out accurate counterweight.
The utility model has designed hydraulic lever formula counter weight device, and is simple in structure, and counterweight is accurately quick, helps the moulding rapidly and efficiently of electric spark.
