Embodiment Construction

[0020] like figure 1 As shown, a movable tool post power unit includes a pneumatic power unit and a hydraulic power unit. The pneumatic power unit includes air source, air filter 1, pneumatic electromagnetic reversing valve 2, preload pressure reducing valve 3, preload pressure gauge 4, working pressure reducing valve 5, working pressure gauge 6, pneumatic shuttle valve 7 , Lubricator 8. The hydraulic power unit includes a fuel tank 9 , an oil filter 10 , an air-liquid pump 11 , an accumulator 12 , an oil pressure gauge 13 , an electromagnetic ball valve 14 , a high-pressure rubber hose 15 , and a moving tool rest cylinder 16 .

[0021] The air source is connected to the inlet of the air filter 1 through the pipeline 0-1, and the outlet of the air filter 1 is connected to the inlet of the pneumatic electromagnetic reversing valve 2 through the pipeline 1-2. Pneumatic electromagnetic reversing valve 2 has two electromagnets 1DT and 2DT, has three working positions of upper, m...

Abstract

The invention discloses a power unit of a mobile cutter frame. The power unit is characterized by comprising a pneumatic power unit and a hydraulic power unit; a gas source enters a gas-liquid pump in the hydraulic power unit through the pneumatic power unit; the gas-liquid pump proportionally transforms different gas inlet pressures into corresponding oil pressures and outputs the oil pressures from an oil outlet; the oil outlet is connected with a mobile cutter frame oil cylinder for driving the mobile cutter frame. The pneumatic power unit provides three different gas pressures for the gas-liquid pump; by the gas-liquid pump in the hydraulic power unit, the proportional transform from the gas pressure to the oil pressure is realized; an energy accumulator can provide an oil return space for pre-fastening adjustment of the mobile cutter frame and is capable of keeping the pressure and supplementing oil during working of the mobile cutter frame oil cylinder; and an electromagnetic valve can be used for reliable sealing and total pressure releasing of the pipeline of the mobile cutter frame oil cylinder. In the invention, a rational and reliable power unit can be provided for the mobile cutter frame, so the working quality of the mobile cutter frame can be guaranteed fully.

Description

technical field [0001] The invention relates to a power unit, in particular to a power unit for a movable tool holder. Background technique [0002] At present, when boring deep holes in machining, ordinary fixed boring tool holders are usually used. The fixed boring tool holder is characterized in that the boring tool holder is It is fixed, and the retracting action of the boring tool cannot be realized. Therefore, when the workpiece is found to be faulty during the boring process and the boring of the workpiece is completed, when the boring bar withdraws from the bored hole of the workpiece, the boring tool will Scratches are formed on the surface of the workpiece, which affects the processing quality of the workpiece. In the field of electric power, widely used pipes, some of which have certain processing requirements for the inner wall of the pipe, need to use deep hole boring processing, use a fixed boring tool holder during the boring process, and it is inevitable tha...
