Hydraulic station and control system and method

Abstract

The invention provides a hydraulic station. The hydraulic station comprises a hydraulic oil storage and delivery mechanism and a functional motion circuit. The hydraulic oil storage and delivery mechanism comprise an oil inlet path and an oil return path. A one-way valve is arranged on the oil inlet path. The oil inlet path, the functional motion circuit and the oil return path are connected in sequence. A spindle release and clamping tool circuit, a tool changer moving circuit and a brake motion circuit are formed by the functional motion circuit and connected in parallel. The invention further provides a control method of the hydraulic station. The control method of the hydraulic station comprises the following steps that the brake motion circuit acts, the spindle release and clamping tool circuit acts, and the tool changer moving circuit acts. Correspondingly, the invention provides a control system of the hydraulic station. According to the hydraulic station and the control methodand system of the hydraulic station, hydraulic oil can be cooled and filtered through a filtering and cooling circuit; and when oil needs to be supplied to the functional motion circuit, a user just needs to close a cooling electromagnetic valve, oil is then supplied to the functional motion circuit, and the response speed is high.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a hydraulic station and a control system and method. Background technique [0002] Patent document 103615439B discloses a filtering device and filtering method for internal circulation of a hydraulic station, wherein the pump is connected to the first valve block, the second valve block, and the third valve block through pressure pipes, and any two valves of the three A filter is arranged between the blocks, and the first valve block, the second valve block and the third valve block are respectively connected to the oil return pipe. According to the self-report of this patent document, compared with the prior art, it has the following advantages: three filters are used, the automatic control and alarm switching of the secondary filter is implemented, and the filtering effect is excellent. The cartridge valve used is a large flow valve, which has strong pollution resistance. The idle filter ...

Problems solved by technology

However, the filtering device provided by this patent document is a separate circuit, which cannot be combined with the existing functional circuit in the hydraulic station for filtering, which increases the structural complexity of the hydraulic station; and when the functional circuit operates, an additional oil pump is required. Difficult to achieve simultaneous filtration, cooling and functional circuit oil supply
