Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
Fig. 1 shows balance and the fastening system of the vertical slide unit of a kind of numerically-controlled machine, comprises reducing valve 1, fluid-control one-way valve 2, equilibrium valve 3, balancing cylinder 4, machine pillar 5 and vertical slide unit 6. Vertical slide unit 6 is arranged in the side of machine pillar 5, and balancing cylinder 4 is arranged on another side, side of machine pillar 5, and the piston rod of balancing cylinder 4 is connected with vertical slide unit 6 by slip rope pulley mechanism, and pulley is arranged on machine pillar 5. On balancing cylinder 4, chamber oil inlet and outlet end is provided with fluid-control one-way valve 2, equilibrium valve 3 and reducing valve 1, on the oil outlet of fluid-control one-way valve 2 and balancing cylinder 4, chamber connects, equilibrium valve 3 and reducing valve 1 are arranged in parallel the oil-in end at fluid-control one-way valve 2, the oil outlet connected tank of equilibrium valve 3, the oil-in of reducing valve 1, also namely with the interface P welding system pressure oil of pressure source. The oil circuit control welding system pressure oil of fluid-control one-way valve 2.
The principle of work of the present invention is: when hydraulic efficiency system normal operation, fluid-control one-way valve 2 is opened by pressure oil, achieve the effect two-way circulated, pressure oil can ensure that under the acting in conjunction of reducing valve 1, fluid-control one-way valve 2, equilibrium valve 3 balancing cylinder 4 runs downward or upward, thus realizes the operation up and down of vertical slide unit 6. When vertical slide unit moves for 6 times, on balancing cylinder 4, chamber fluid is through fluid-control one-way valve 2 reversed flow, flows back to fuel tank through equilibrium valve 3, and system balances the weight of vertical slide unit 6 self by the pressure that equilibrium valve 3 is set up, and now reducing valve 1 cuts out; And when moving on vertical slide unit 6, system pressure oil enters chamber on hydro-cylinder balancing cylinder 4 through reducing valve 1, fluid-control one-way valve 2, unnecessary fluid can flow back to fuel tank from equilibrium valve 3, and the adjustment pressure of reducing valve 1 is equal with the pressure of equilibrium valve 3. When lathe power-off, after hydraulic closure system, because of system pressure falls away, fluid-control one-way valve 2 cuts out because of pressure out of hand, is enclosed in oil cylinder by the pressure oil in balancing cylinder 4, makes vertical slide unit remain on corresponding position and stops.
The present invention utilizes the hydraulic efficiency system of former lathe itself, hydraulic pressure balancing cylinder 4 is installed, and install the closedown structure of fluid-control one-way valve 2 additional, vertical slide unit 6 can be made when running up and down like this to eliminate slide unit effect of weight, when can avoid again lathe stopping work, the phenomenon making vertical slide unit glide because equilibrant disappears occurs.
Hydraulic pressure balancing cylinder 4 of the present invention installs fluid-control one-way valve 2 additional, and the pulling force exported by adjustment hydraulic ram 4 balances the deadweight of vertical slide unit 6, makes the impact that vertical slide unit 6 is not conducted oneself with dignity when vertical movement. The use of fluid-control one-way valve 2 can stop hydraulic efficiency oil reversed flow in hydraulic efficiency system, needs to play locking and pressure maintaining effect during locking in vertical axes; Also can utilize oil circuit control during work, fluid-control one-way valve 2 is opened, ensure that vertical slide unit 6 can run up and down. Therefore, this structure can meet hydraulic pressure balancing cylinder 4 to-and-fro movement, can reach again the oil circuit of locking hydro-cylinder 4, makes the object that vertical slide unit 6 can stop at an arbitrary position.
Effective place of the present invention: can fundamentally reduce fault and occur and cut down a large amount of platform man-hour of stopping, it is to increase efficiency, cost-saving.
Above in conjunction with accompanying drawing to invention has been exemplary description; the realization of obvious the present invention is not subject to the restrictions described above; as long as have employed the various improvement that the design of the method for the present invention carries out with technical scheme; or without improving, the design of the present invention and technical scheme directly applied to other occasion, all in protection scope of the present invention.
