The specific embodiment
A kind of hydraulic drive type clamping device as depicted in figs. 1 and 2, comprise base 1, for the hold assembly of holding workpiece 3, for driving the hydraulic cylinder 6 of hold assembly clamping work pieces 3 and for fixedly mounting the support component of hydraulic cylinder 6, also comprising for controlling the hydraulic control system of described hydraulic cylinder 6 actions, 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 ends are connected with described hold assembly, the rodless cavity of described hydraulic cylinder 6 and rod chamber are communicated with M mouth and the N mouth of reversal valve 1 respectively, the S mouth of described reversal valve 1 is communicated with fuel tank, on pipeline between the R mouth of described reversal valve 1 and oil pump 9 outlets, be provided with check valve 10, between described check valve 10 outlets and the R mouth of described reversal valve 1, be provided with accumulator 11 and pressure switch 12, described oil pump 9 exits are 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 being 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-pins.
As shown in Figure 2, described reversal valve 1 is 3-position 4-way solenoid directional control 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 the utility model hydraulic drive type clamping device is: as depicted in figs. 1 and 2, first this hydraulic drive type clamping device is fixedly mounted on to operating position, when the access of the left position of 3-position 4-way solenoid directional control valve 1, hydraulic cylinder 6 rodless cavity pressure are greater than its rod chamber pressure, piston moves right, after hydraulic cylinder 6 promotion pressure heads 4 coordinate workpiece pressing 3 with parallels 2, oil pump 9 works on intrasystem input pressure is raise, 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 by overflow valve 8 off-loads, now check valve 10 is closed automatically, 6 of hydraulic cylinders are by accumulator 11 pressurizes.When oil pressure is not enough, pressure switch 12 resets and makes the next access of bi-bit bi-pass solenoid directional control valve 7, and overflow valve 8 cuts out, and oil pump 9 impels check valve 10 to open, and oil pump 9 is to the rodless cavity supercharging of hydraulic cylinder 6, thereby impels pressure head 4 to continue workpiece pressings 3.After workpiece 3 machines, the right position access of 3-position 4-way solenoid directional control valve 1, hydraulic cylinder 6 rod chamber pressure are greater than its rodless cavity pressure, and piston is to left movement, when hydraulic cylinder 6 band dynamic heads 4 leave workpiece 3, now operator can take off the workpiece processing 3 easily.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belongs in the protection domain of technical solutions of the utility model.
