A mechanism which drives the spindle rotor to move up and down is organically combined on the spindle, so that the integral structure of the air-flotation spindle is simplified, parts of the air-flotation spindle are reduced, the weight of the air-flotation spindle is lightened, and accordingly manufacturing cost of the machine is also lowered.

Description

A kind of Digit Control Machine Tool air supporting electricity main shaft
Technical field
The utility model relates to air supporting electricity spindle technology field, specially refers to the improvement of Digit Control Machine Tool with air supporting electricity main axle structure.
Background technology
Air-floating main shaft (being called air spindle again) refers to the sliding bearing of gas (normally air, but also might be other gas) as lubricant.Air-floating main shaft waits the support that realizes by the pressure air that imports in bearing bore, because the slit of pressure release is minimum in the bearing bore, guaranteed the suspension of air-floating main shaft.Air-floating main shaft is converted into magnetic force to electric power with coil, and then drives the rotation that rotor is done the high speed suspension.
Air-floating main shaft is not owing to there is the machinery contact, and the degree of wear has dropped to minimum, thereby it is stable to guarantee that precision remains; And air-floating main shaft can be when providing high rotating speed, power loss dropped to minimum, and makes the heat of generation very little.Rotating speed can be above 300,000 rev/mins.
Air-floating main shaft has the high-revolving advantage of high accuracy, has obtained extensive use at rotating machinery.The air supporting electricity main shaft of using on the PCB Digit Control Machine Tool at present all only possesses the function of rotor rotation, this air supporting electricity main shaft also needs to add the driving of linear motor when carrying out boring work or the transmission that rotation motor adds screw mandrel could realize the upper and lower motor function of main shaft, and then finishes the tool-chip process.Existing this main axle structure makes that the complicated integral structure of lathe, parts are many, Heavy Weight, the speed of service be slow, the manufacturing cost height.
The utility model content
Technical problem to be solved in the utility model provide a kind of not only rotor main shaft can high speed rotating and also the rotor main shaft novel air hydrostatic numerical control lathe that can move up and down with air supporting electricity main shaft.
Designed a kind of air supporting electricity main axle structure device that integrates rotation motor, line motor and static air pressure air-bearing according to above-mentioned problem the utility model that needs to solve, specific implementation is as follows:
A kind of Digit Control Machine Tool air supporting electricity main shaft, comprise the main shaft shell and be located at the interior spindle rotor of main shaft shell, the last air-bearing and the following air-bearing of two supporting spindle rotors are housed on the inwall of main shaft shell, line motor stator, rotation motor stator also are housed on the inwall of main shaft shell, corresponding line motor stator, the rotation motor stator of being installed is separately installed with line motor rotor and rotation motor rotor on spindle rotor
Described line motor stator, rotation motor stator also are connected with driving governor.Described spindle rotor top is formed with the move up and down rotor spacing ring up and down of position of restrict rotor.
For making the main axle structure assembling accurate, rational in infrastructure, line motor stator, last air-bearing, rotation motor stator, following air-bearing are successively set on the inwall of main shaft shell from top to down.
The utility model has following remarkable result compared to existing technology: the shell in this air supporting electricity main shaft be the stator of rotation motor be again the stator of line motor, rotor in the air-floating main shaft be the rotor of rotation motor be again the mover of linear motor, in the course of work, the main shaft shell is fixed, rotor in the main shaft is in the control of the controller action that rotates and move up and down, and it can realize different rotating speeds, different moving up and down apart from, the different speed that moves up and down and the requirement of frequency.The air supporting electricity main shaft that the utility model proposes organically combines the mechanism that the drive shaft rotor moves up and down on main shaft, makes that the overall structure of air-floating main shaft is simplified, parts reduce, weight saving, thereby has also lowered the manufacturing cost of lathe.
Description of drawings
Fig. 1 is the cutaway view of the utility model air-floating main shaft.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing.
Referring to Fig. 1, a kind of Digit Control Machine Tool air supporting electricity main shaft, comprise main shaft shell 6 and be located at the interior spindle rotor 2 of main shaft shell, the last air-bearing 8 and the following air-bearing 10 of two supporting spindle rotors 2 are housed on the inwall of main shaft shell, line motor stator 7, rotation motor stator 9 also are housed on the inwall of main shaft shell, for topology layout rationally is fixed in line motor stator 7 on the air-bearing 8, rotation motor stator 9 is located between air-bearing 8 and the following air-bearing 10.
On spindle rotor 2, be separately installed with line motor rotor 1 and rotation motor rotor 3, line motor stator 7, the rotation motor stator 9 installed on the corresponding respectively main shaft outer casing inner wall of line motor rotor 1 and rotation motor rotor 3.
Line motor stator 7, rotation motor stator 9 also are connected with driving governor, set rotating speed by driving governor, and the speed that moves up and down, distance and frequency etc. drive rotor by stator again and do rotation or move up and down.Be the position that the restriction spindle rotor moves up and down, be formed with rotor spacing ring 5 up and down at spindle rotor 2 tops.
In the motion process, the main shaft shell is fixed, and the rotor on the main shaft is done rotation simultaneously and moved up and down in main shaft, adorning chuck 4 on the rotor of main shaft, clip cutter 11 on the chuck, cutter is finished workpiece chips work in the rotation of rotor and the process that moves up and down.
The foregoing description only is a preferred implementation of the present utility model; in addition; the utility model can also have other implementations; for example with on this air-floating main shaft application and other rotating machinerys except that Digit Control Machine Tool; that is to say; under the prerequisite that does not break away from the present utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
