Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings of the specification.
As shown in Fig. 1-Figure 14, a kind of high revolving speed heavy type static pressure turntable of high-precision, turret base 3 is entire static pressure turntable
Basis, center have transverse bearing hole 3.2, and the outer ring of transverse bearing 6 is fixed by bolt hole 6.1 and turret base 3, to limit
The radial displacement of turntable 2.The bottom end of turret base 3 is evenly distributed with lubricating pad 3.1 under 12 sectors, passes through the lower guideway 2.2 with turntable 2
Cooperation provides upward bearing capacity and supports static pressure turntable.Lubricating pad is connected by bolt with turret base, is conveniently replaceable.Turntable bottom
The bottom of seat 3 is provided with an oil return hole 3.3, to collect the oil liquid of 12 lubricating pads outflow.It is arranged in 3 side wall of turret base
Motor room 3.4 be used to install driving turntable rotation motor.Three pick up the ears 4 along 120 ° of equidistant uniform weldings in turret base
