Structure Introduction

The beam is placed in front of the column, driven by a dual-shaft extension AC motor, and driven by gears, worm gears, and lead screws to make the beam move vertically on the column. There are 4 hydraulic clamping points behind the beam. The sliding surface of the beam and the column is treated with a wear-resistant soft belt.

Hydraulic balance of left & right tool post ram

The hydraulic balance of the left & right tool post ram consists of one-way valve, overflow valve, and accumulator, and the balance pressure can be adjusted appropriately through the overflow valve to ensure that the tension of the tool post ram is close when it rises or falls. The accumulator is a leather bag type, filled with nitrogen gas at pressure of 2.0MPa to compensate for pressure drop caused by special reasons in the balance system.

The lubrication of the gearbox and working table is supplied oil by the overflow oil of the overflow valve; The lubrication of the left and right tool posts and the lubrication of the crossbeam are provided by the automatic lubrication oil pump.

The recommended pressure for each regulating valve is: the alarm value of the low-pressure protection pressure relay in the static pressure system is 1.5MPa; The low-pressure protection of the guide rail oil chamber is set to 0.13MPa by the pressure controller; The working pressure for variable speed, balance, and clamping is 3.0MPa, adjusted by the overflow valve.

In order to ensure the cleanliness of the working oil and the safe and reliable operation of hydraulic components, the filters in the hydraulic system should be regularly cleaned and replaced. The hydraulic oil used for this machine tool is No. 46 hydraulic oil, the hydraulic station of this machine tool is connected to the base of the working table. When filling the hydraulic station with oil, due to the storage of oil in the hydraulic pipeline, hydraulic oil should be supplemented appropriately based on the decrease in liquid level after the first use of the machine tool.
