Customized Heavy duty double column lathe machine CK5240

The machine tool is composed of left and right columns, top beam, connecting beam and workbench base to bear the load during cutting. The crossbeam moves up and down along the column guide rail, the lifting motor and worm gear reducer of the crossbeam are placed on the top beam, the crossbeam is locked on the column by the hydraulic locking device based on the lever principle, and the up and down movement and locking device of the crossbeam are controlled by related electrical appliances, that is, the hydraulic locking device is automatically released when the crossbeam rises or falls, and the hydraulic locking device is automatically locked when the crossbeam is fixed, The lifting operation associated button of the beam is on the suspension button station.

The main gearbox divided into high and low gears is installed at the rear of the workbench base and directly started by the variable frequency motor. The advantage of this structure is that the speed and torque can be configured more reasonably according to the different needs of the processed workpiece, so as to improve the work efficiency.

The guide rail of the workbench is inlaid with zinc aluminum copper alloy wear-resistant plate. During operation, the guide rail plate is filled with pressure oil (2-4kg / cm ²), In order to improve the bearing capacity of the worktable, two double row roller bearings nnk30 series are installed on the spindle of the worktable, and their inner rings are tapered to adjust the radial clearance and ensure that the spindle can work stably under high precision.

The feed box is installed at the end of the beam and driven by the servo motor. Two groups of electromagnetic clutches are installed in the feed box to select the horizontal and vertical feed of the tool holder. The feed speed, i.e. working feed and rapid feed, is controlled by the speed regulating button. The cross switch and speed regulating knob in the feed direction are installed on the button station, which makes the operation simple.

The right vertical tool holder is installed on the beam through the sliding seat. The horizontal and vertical movement of the tool holder is realized by the feed box through the lead screw and smooth screw. The vertical tool holder can rotate ± 30 ° on the sliding seat to realize the processing of the conical surface. The lead screw and smooth screw are equipped with an operating handle to adjust the position of the tool holder. The weight of the ram of the vertical tool holder is offset by the pressure oil of the balance oil cylinder, Thus, the service life of the product is increased. At the same time, a manual lubrication pump is installed on the beam and the tool holder to ensure processing lubrication.
