Detailed description of the invention
A kind of hydraulic drive type clamping device as depicted in figs. 1 and 2, comprise base 1, for holding workpiece 3 hold assembly, for driving the hydraulic cylinder 6 of hold assembly clamping work pieces 3 and the support component for fixedly mounting hydraulic cylinder 6, also comprise the hydraulic control system for controlling the action of described hydraulic cylinder 6, described support component is U-shaped installing rack 5, the cylinder body of described hydraulic cylinder 6 is fixedly mounted on described U-shaped installing rack 5, described hydraulic cylinder 6 knock-pin end is connected with described hold assembly, the rodless cavity of described hydraulic cylinder 6 is communicated with N mouth with the M mouth of reversal valve 1 respectively with rod chamber, the S mouth of described reversal valve 1 is communicated with fuel tank, pipeline between the R mouth of described reversal valve 1 and oil pump 9 export is provided with check valve 10, described check valve 10 exports and be provided with accumulator 11 and pressure switch 12 between the R mouth of described reversal valve 1, described oil pump 9 exit is provided with overflow valve 8, the hydraulic control mouth of described overflow valve 8 is provided with reversal valve 27.
As shown in Figure 1, described hold assembly comprises the parallels 2 that is fixedly mounted on described base 1 and coordinates the pressure head 4 for workpiece pressing 3 with described parallels 2, and described pressure head 4 is arranged on the end of described hydraulic cylinder 6 knock-pin.
As shown in Figure 2, described reversal valve 1 is three-position four-way electromagnetic directional valve, and described reversal valve 27 is bi-bit bi-pass solenoid directional control valve.
As shown in Figure 1, described U-shaped installing rack 5 welds or is mounted by means of bolts on described base 1.
The course of work of hydraulic drive type clamping device of the present invention is: as depicted in figs. 1 and 2, first this hydraulic drive type clamping device is fixedly mounted on operating position, when the left position access of three-position four-way electromagnetic directional valve 1, hydraulic cylinder 6 rodless cavity pressure is greater than its rod chamber pressure, piston moves right, coordinate after workpiece pressing 3 when hydraulic cylinder 6 promotes pressure head 4 with parallels 2, oil pump 9 works on and intrasystem input pressure is raised, when pressure reaches the setting value of pressure switch 12, pressure switch 12 sends signal and makes the upper access of bi-bit bi-pass solenoid directional control valve 7, oil pump 9 is namely by overflow valve 8 off-load, now check valve 10 is closed automatically, hydraulic cylinder 6 is by accumulator 11 pressurize.When oil pressure is not enough, pressure switch 12 resets and makes the access of bi-bit bi-pass solenoid directional control valve 7 bottom, and overflow valve 8 cuts out, and oil pump 9 impels check valve 10 to open, and oil pump 9 to the rodless cavity supercharging of hydraulic cylinder 6, thus impels pressure head 4 to continue workpiece pressing 3.After workpiece 3 machines, the right position access of three-position four-way electromagnetic directional valve 1, hydraulic cylinder 6 rod chamber pressure is greater than its rodless cavity pressure, and piston is to left movement, when hydraulic cylinder 6 is with dynamic head 4 to leave workpiece 3, now the workpiece 3 processed can take off by operator easily.
