Summary of the invention
The object of the present invention is to provide high-speed high-precision servo linear motor sliding table, can solve backlass, motion delay, friction, vibration, noise and wear problems that traditional driving-chain exists effectively.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: high-speed high-precision servo linear motor sliding table, it is characterized in that: comprise the slide unit base, slidely connect down slide unit on the slide unit base, slidely connect slide unit on the following slide unit, last slide unit and following slide unit are respectively in the X-axis and the enterprising line slip of Z-direction that become 90 °.
Preferably, slide unit base top both sides are provided with Z axle line slideway, following slide unit is connected on the Z axle line slideway, be provided with Z axle servo linear motor between following slide unit and the Z axle line slideway, the stator of Z axle servo linear motor is fixed on the slide unit base, the fixedly connected slide unit down of the mover of Z axle servo linear motor, following slide unit is by driving linear slide on Z axle line slideway of Z axle servo linear motor.
Further, Z axle servo linear motor is arranged in the middle of two Z axle line slideways, make down slide unit when sliding stressed evenly, avoid down the slide unit unbalance stress and with the friction of Z axle line slideway generation, reduce noise and wearing and tearing.
Further, both sides, following slide unit top are provided with the X-axis line slideway, last slide unit is connected on the X-axis line slideway, be provided with the X-axis servo linear motor between last slide unit and the X-axis line slideway, the stator of X-axis servo linear motor is fixed on down on the slide unit, the mover of X-axis servo linear motor is fixedly connected on the slide unit, and last slide unit is by driving linear slide on the X-axis line slideway of X-axis servo linear motor.
Further, the X-axis servo linear motor is arranged in the middle of two X-axis line slideways, make slide unit when sliding stressed evenly, avoid the slide unit unbalance stress and with the friction of X-axis line slideway generation, reduce noise and wearing and tearing.
Further, slide unit base, upward slide unit and the moulding of following slide unit employing iron casting make it have stronger absorbing and structural rigidity, have guaranteed the stationarity of moving component.
The present invention has following beneficial effect owing to adopted technique scheme:
One, simple in structure, because linear electric motors do not need thereby to make the structure of system itself greatly simplify that weight and volume descends widely to the be in line attachment device of motion of rotation motion;
Two, positioning accuracy height, in the straight-line place of needs, linear electric motors can be realized direct transmission, thereby can eliminate the various position errors that intermediate link is brought, so the positioning accuracy height; As adopt microcomputer control, then can also improve the positioning accuracy of whole system widely;
Three, reaction speed is fast, highly sensitive, servo-actuated is good, linear electric motors accomplish that easily its mover supports with magnetic suspension, thereby make and remain certain air-gap between mover and the stator and do not contact, that this has just eliminated is fixed, the contact friction resistance between mover, thereby the sensitivity, rapidity and the servo-actuated that have improved system widely;
Four, safe and reliable, the life-span is long, linear electric motors can be realized non contact transmission power, the mechanical friction loss is almost nil, so fault is few, freedom from repairs, thereby safe and reliable, the life-span is long.
To sum up, high-speed high-precision servo linear motor sliding table of the present invention, simple in structure, velocity interval is wide, good speed characteristics, acceleration is big, positioning accuracy is high, noise and wearing and tearing are little, can satisfy the needs of Digit Control Machine Tool development fully, compare more economical practicality with traditional slide unit; The mechanism that can be used for the high-accuracy feeding of numerically controlled lathe also can be used for the accurate slide unit of CNC milling machine, machining center.
