Problems solved by technology

[0002] With the increase of output, after a long period of full-load operation, it is found that the hydraulic station of the machine tool has problems of varying degrees, such as the oil suction port and the inner wall of the oil tank cannot be cleaned, which reduces the quality of hydraulic oil and increases the wear of the inner wall. jam
Frequent oil leakage in the oil tank causes excessive consumption of hydraulic oil, resulting in waste
The parts and pipes of the hydraulic station are seriously aging, resulting in unstable hydraulic pressure, unable to output the pressure required for processing, which can easily cause the clamping force of the chuck to be unstable and deform the workpiece, and there is a safety hazard of the workpiece flying out

Abstract

The invention discloses a machine tool hydraulic pressure station which comprises an oil tank and a radiator, wherein a three-phase asynchronous motor and a valve block are mounted on the upper top surface of the oil tank; a variable pump is mounted on one side wall of the three-phase asynchronous motor; a pressure reducing valve, a pressure retaining valve and a solenoid valve are mounted above the valve block from bottom to top in sequence; one end of the variable pump communicates with an oil suction opening filter arranged inside the oil tank through an oil suction tube; the other end of the variable pump communicates with the radiator and the valve block through a radiator oil inlet tube and a main pressure tube; the radiator communicates with the oil tank through a radiator oil return tube; and a knife tower oil port A, a knife tower oil port B, a chuck oil port A and a chuck oil port B are arranged on the side wall of the valve block. According to the machine tool hydraulic pressure station, pressure stability is guaranteed, workpiece deformation caused by pressure stability is reduced, processing safety of equipment is guaranteed, and guarantee is provided for increasing first-pass yield of workpieces; and meanwhile, consumption of hydraulic oil is reduced and waste is reduced.

Description

technical field [0001] The invention belongs to a hydraulic device, in particular to a machine tool hydraulic station. Background technique [0002] With the increase of output, after a long period of full-load operation, it is found that the hydraulic station of the machine tool has problems of varying degrees, such as the oil suction port and the inner wall of the oil tank cannot be cleaned, which reduces the quality of hydraulic oil and increases the wear of the inner wall. clogged. Frequent oil leakage in the oil tank causes excessive consumption of hydraulic oil and waste. The parts and pipes of the hydraulic station are seriously aging, resulting in unstable hydraulic pressure, unable to output the pressure required for processing, which can easily cause the clamping force of the chuck to be unstable and deform the workpiece, and there is a safety hazard of the workpiece flying out. Contents of the invention [0003] The present invention is proposed in order to ov...
