Description
Technical field
The utility model relates to a kind of electric main axle structure, particularly a kind of car, mills two electricity consumption main axle structures, and the machine of being mainly used in belongs on the stock-removing machine.
Background technology
At present, electric main axle structure is that a casing is arranged in the lathe, is provided with main shaft in casing, and main shaft endoporus place is provided with tool-broaching mechanism, supports by forward and backward end cap and forward and backward bearing block between casing and the main shaft.On main shaft, be provided with the rotor winding, be positioned at the rotor winding outside at box inside and be provided with stator winding.Rotor drive main shaft rotates with respect to casing during work, and the milling cutter fixing by tool-broaching mechanism can rotate with main shaft, reaches the purpose of milling workpiece.
Existing car, mill the Compositions of metal-working machines lathe,, be equipped with secondary main shaft of milling and turning head usually, with the car of realizing part, mill processing according to the regulation of JB/T 10889.This configuration takes up room, thereby has reduced the free space of lathe inside, and the cost height has reduced the reliability of lathe simultaneously.Respectively take a reference axis because mill main shaft and knife rest, also just reduced the extensibility of complete machine layout.For example when the cutting slender axles, if use lower slide turning, then lower slide and centre frame interfere easily, and this will reduce the piece surface crudy even cause flutter to collapse the cutter phenomenon.In addition, when knife rest was configured in the main shaft below, smear metal and cooling fluid brought a lot of difficulties can for the protection of lower guideway pair, make the complete machine structure complexity.
Summary of the invention
The purpose of this utility model provide a kind of take up room little, increase that the inner free space of lathe, cost are low, designs simplification, can prevent that flutter from collapsing the car of cutter phenomenon, milling two electricity consumption main axle structures, overcome the deficiencies in the prior art.
Car of the present utility model, mill two electricity consumption main axle structures, comprise casing and the main shaft that is positioned at box inside, front end at casing is fixedly connected with end cap, front-end bearing pedestal, between the front portion of main shaft and bearing block, be provided with fore bearing, leave annulus at the front-end bearing pedestal and the outside, main shaft front portion, in this space, be provided with the piston body that is enclosed within the main shaft outside, front side at piston body forms front chamber, rear side at piston body forms rear chamber, be fixed with the link fluted disc of annular at the trailing flank of piston body, be fixed with the interior end-toothed disc of annular at the front step place of main shaft, on the step of the front side of casing, be fixed with the outer end-toothed disc of annular, the link fluted disc is simultaneously with interior during cylinder action, outer end-toothed disc is meshed, and is respectively equipped with the oil circuit that links to each other with rear chamber with front chamber on casing.
Car of the present utility model, mill two electricity consumption main axle structures, can carry out car, mill the dual mode conversion, very convenient, processing ease, it is little to take up room, and the usage space of lathe inside is increased.During installation, oil circuit and hydraulic system on front chamber and the rear chamber's casing are joined.During the milling workpiece, front chamber is in the drain charge state, this moment piston body to be in left side position (be anteposition, position as shown in Figure 5), make with the fixedly connected end-toothed disc of piston body and separate with outer end-toothed disc with interior end-toothed disc simultaneously, main shaft can rotate with respect to casing, realization milling function; During turner, move right by hydraulic mechanism driven plunger body, rear chamber is in the drain charge state, and the link fluted disc of fixedlying connected with piston body is meshed with inside and outside end-toothed disc simultaneously, and main shaft is maintained static, and realizes the turning function.
