Description
Technical field
The utility model relates to a kind of Digit Control Machine Tool, specifically is the device of control rotary table angular displacement on a kind of Digit Control Machine Tool.
Background technology
In Digit Control Machine Tool, often to run into rotary table shown in Figure 12, need us accurately to control the angular displacement of rotary table 2, the way that solves is exactly that A roller gear or a friction pulley 3 identical with rotary table 2 centres of gyration is set below rotary table 2, it is fixed on the lathe bed or slide unit of lathe, if the revolution of rotary table 2 does not need 360 °, then A roller gear or friction pulley 3 can be fan-shaped friction pulley or sector gear.The advantage of friction pulley transmission is that accurately shortcoming is to skid easily, and the control ratio of normal pressure is difficulty; Gear-driven advantage is that transmission realizes easily, by the engaged transmission of A roller gear 3 with B gear 6, and the angular displacement of control rotary table, shortcoming is the bad elimination of backlash.In design in the past and the application,, adopt following two kinds of methods usually in order to eliminate backlash:
A kind of method is that the B gear is made two up and down, and does not open with the elimination gap with spring the centre, and then use screw in compression.This method is used often in the past, and is cumbersome, and effect neither be fine.
Another kind method is with two all drive and rotating in opposite direction B
1Gear, B
2Gear is controlled.When requiring rotary table to rotate in the counterclockwise direction, B
1The torque that is applied on the gear is greater than B
2Gear is passive, B then when requiring rotary table to clockwise rotate
2The torque that is applied on the gear is greater than B
1The torque that gear applied.This method is obviously good than first method, and shortcoming is to take up an area of greatly the cost height.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of device of controlling the rotary table angular displacement, and is simple in structure, and it is effective to eliminate backlash, can accurately make the rotary table angular displacement.
For achieving the above object, the technical scheme that the utility model adopted is: described a kind of device of controlling the rotary table angular displacement comprises rotary table, A gear, B gear, the A gear is fixed on bed piece or the slide unit, and an end of rotary table is provided with the gyroaxis that is total to axial line with described A central gear axis; The B gear that is meshed with the A gear is contained in the other end of rotary table and can rotates under Motor Drive and drive rotary table and rotate around described gyroaxis; The beam warp elastic coupling of described B gear connects with the axle of motor, is provided with elastic pressuring clamping device in a side of B gear, and this elastic pressuring clamping device is pressed to the A gear with described B gear and eliminated between cog back lash between B gear and the A gear.
Below the utility model made further specify.
A kind of structure of described elastic pressuring clamping device is, it comprises spring, wheel seat, support, and support is fixed on the rotary table, and wheel seat is connected with support by spring and can slides in support.
A kind of structure of described elastic pressuring clamping device is, it comprises spring, push rod, ram seat, bearing, and push rod links to each other with ram seat by spring and can slide in ram seat, and ram seat is fixed on the bearing, and bearing is fixed on the rotary table.
Further, between motor and the B gear reduction box is housed.
Further, motor and B gear, reduction box connect into an integral body, and this integral body is fixed on the rotary table by elastomer block.
Further, the spring in the described hold down gag can replace with hydraulic jack.
Wheel seat in the hold down gag in the utility model or push rod are pressed to the B gear under the effect of spring force, make the B gear do slight displacement to the A gear, the gap when eliminating the gear pair engagement.
Compared with prior art, it is effective that the utility model is eliminated backlash, can accurately control the rotary table angular displacement, and simple in structure, cost is low.
