Talk about the structure of CNC vertical lathe and your characteristics

1. The first is its main moving part: the wide adjustable magnetic DC motor powered by thyristor drives the workbench to rotate through a two speed planetary gearbox. The worktable adopts high-precision double row cylindrical roller bearing for centering in the radial direction, preloaded constant current and static pressure guide rail in the axial direction, and is equipped with temperature control and temperature protection devices. The appropriate flow can be selected according to the load and temperature. When the mobile single column CNC vertical lathe suddenly loses power, the accumulator is considered as static pressure power-off protection in the design. The static pressure pump station is equipped with two accumulators, which can still supply oil to the static pressure guide rail for 15 seconds after a sudden power failure, so as not to damage the guide rail.

2. The column moves on the bed and adopts static pressure unloading guide rail.

3. The cross beam body is assembled from the front and rear parts, and the joint surfaces are connected with bolts. The crossbeam moves up and down along the column guide rail. A special static pressure unloading lead screw nut is adopted. The tooth shape is serrated. The hydraulic pressure is adjusted to unload 60% ~ 70% of the total load, and the self-locking characteristics of the sliding lead screw nut are still maintained. The lifting of the beam is driven by the AC motor installed on the top surface of the column. The action sequence is as follows: press the lifting button of the beam → lubricate and supply oil to the guide rail surface → supply oil to the static pressure unloading lead screw nut → loosen the clamping of the beam → the beam automatically rises (falls) to the specified position, loosen the button → the beam is automatically clamped on the column. When the lowering of the beam ends, it will automatically rise by 10 ~ 20mm to ensure that the lead screw is in the same stress state when it rises.

4. Secondly, the worktable, base, main gearbox and other main moving parts of the single column CNC vertical lathe are not connected with the feed moving parts such as bed, column, beam and tool holder. The accuracy between them can be adjusted independently and do not interfere with each other. In addition, the main components such as worktable, base, bed, column, beam and tool holder can be designed into several modules respectively, so as to be assembled with modules of different specifications, Meet the needs of user selection.

5. The workbench is equipped with claws for radial and axial adjustment. A special workpiece support seat is used for clamping the workpiece larger than the diameter of the worktable. The support seat can ensure that the weight of the workpiece is borne by the static pressure guide rail of the worktable. The support seat is equipped with sector plate to connect the whole support seat into a whole, which is convenient for operation and workpiece clamping.

6. The feed movement part of mobile CNC vertical lathe: the movement of slide plate and ram adopts preloaded constant current static pressure guide rail, which is powered by AC servo motor and driven by preloaded ball screw pair.

7. Electrical follow-up part: the measuring device equipped with grating ruler is on the auxiliary sliding seat. The feedback signal of the grating is transmitted to the high-speed data processing system to drive the high-speed tracking servo motor, and the follow-up tool holder is driven to move through the ball screw.

8. The machine tool has two coordinate axes X and Z and an electrical follow-up axis (W axis). X and Z axes can be linked, and W axis has the function of high-speed real-time tracking. The machine tool adopts Siemens FM-NC numerical control system and indromat high-speed real-time tracking system.
