Technical Field

The present invention relates to a hydraulic drive apparatus.

Background

Energy conservation and environmental protection are the problems concerned by all countries in the world at present, low energy consumption is more and more regarded as a great breakthrough point of technical innovation by the industry, and the machine tool industry is no exception. At present, the energy efficiency problem of the machine tool is generally regarded, and various measures for improving the energy efficiency of the machine tool are researched and implemented. In short years, the development of energy-saving and environment-friendly machine tools is vigorous, green manufacturing is trending, and innovation of energy-saving structures is urgent.

The machine tool is composed of mechanical, electrical and hydraulic parts, wherein the hydraulic part provides balance load, tool loosening and clamping, machine tool lubrication and the like for the machine tool, plays a vital role in machine tool performance, and is also a key part for machine tool energy conservation. At present, most gantry machining centers adopt a hydraulic station to provide gravity balance for the movement of ram components of a machine tool, loose and tight clamping of main shaft cutters, cutter changing of a servo tool magazine and the like. However, the hydraulic station needs to select a motor and an oil pump which are large enough to match the pressure and flow required by the movement of the ram assembly, so that the energy consumption of the machine tool is increased, the cost of the machine tool is increased, and the failure rate of the machine tool is increased.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the hydraulic driving equipment is provided, and the problems that in the prior art, the pressure of a hydraulic station is too large and the flow is too high, so that the cost and the energy consumption are increased are solved.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

The hydraulic driving equipment comprises a hydraulic station, a balance oil cylinder group and a ram component, wherein the balance oil cylinder group is connected with an outlet of the hydraulic station through a rubber pipe; the energy accumulator is connected with the rubber pipe through a valve seat connected to the energy accumulator connector, the energy accumulator connector is fixed with the valve seat through a clamping device, the clamping device comprises an inner hoop matched with an installation section of the energy accumulator connector and a fixed hoop used for fixing the inner hoop on the valve seat, the fixed hoop comprises a first fixed snap ring, a second fixed snap ring and a pair of fastening screws capable of fixing the first fixed snap ring and the second fixed snap ring on the valve seat respectively, the installation section comprises two inner hoops symmetrically positioned on the energy accumulator connector, the inner hoop comprises a first inner snap ring and a second inner snap ring which are matched with the two installation sections respectively and are semi-annular, a first clamping groove for partially accommodating the first inner snap ring is arranged on the inner side surface of the first fixed snap ring, and a second clamping groove for partially accommodating the second inner snap ring is arranged on the inner side surface of the second fixed snap ring, the first fixed snap ring is provided with a first abutting screw which abuts against the first inner snap ring along the axis direction in a penetrating manner, and the second fixed snap ring is provided with a second abutting screw which abuts against the second inner snap ring along the axis direction in a penetrating manner.

Further, the balance oil cylinder group comprises two parallel balance oil cylinders.

Compared with the prior art, the invention has the following beneficial effects:

The hydraulic balance ram device has a simple structure and a scientific and reasonable design, can replace a hydraulic station to balance the ram, and the hydraulic station can meet the auxiliary functions of a machine tool only by selecting a low-power motor and a low-displacement pump, so that the hydraulic design cost is reduced, and the energy consumption of the machine tool is reduced; the system has excellent stability, and can ensure good dynamic performance of the ram component; the ram component can be protected under the condition of power failure, and damage to a machine tool due to load increase under the condition of sudden power failure is prevented. Meanwhile, the energy accumulator in the hydraulic circuit is fixedly connected with the valve seat through the clamping device, so that potential safety hazards caused by displacement or insecure connection of the energy accumulator relative to the valve seat in the use process are effectively prevented.
