Abstract
The utility model discloses hydraulic flat tongs. The hydraulic flat tongs comprise a tong body, a base, a fixed jaw, a movable jaw, a movable tong body and a controlling device. The controlling device comprises a piston rod, a hydraulic oil cylinder, a hydraulic pump, an overflow valve, a one-way valve, and an electromagnetic valve. The hydraulic oil cylinder is installed on the base. The movable tong body is pushed to move by the hydraulic oil cylinder through the piston rod. The piston rod is connected with the movable tong body through a connector. The hydraulic pump, the overflow valve, the one-way valve and the electromagnetic valve are connected with the hydraulic oil cylinder sequentially. The hydraulic flat tongs are simple in structure, capable of enabling a workpiece to be conveniently mounted or dismounted and convenient to use, and effectively relieve the labor intensity, improve production efficiency, and improve machining precision due to moderate squeezing force.
Description
Technical field
The utility model relates to the milling machine field of machining, is specifically related to a kind of hydraulic pressure flat-nose pliers, relates in particular to the control device of CNC milling machine hydraulic pressure flat-nose pliers.
Background technology
At present CNC milling machine hydraulic pressure flat-nose pliers divides manually and automatic two kinds, the hand-hydraulic flat-nose pliers exist use inconvenient, labour intensity is big, production efficiency is low, the big or small problem such as wayward of squeeze force; The automatic hydraulic flat-nose pliers is by program setting moving caliper advance and retreat, though alleviated labour intensity, that workpiece is installed is not necessarily synchronous with the program setting time because of the people, the same problems such as inconvenience, production efficiency are low of using that exist.
The utility model content
The utility model provides a kind of hydraulic pressure flat-nose pliers at the problems referred to above, and purpose is: reduce labour intensity, enhance productivity, improve machining accuracy simultaneously.
Technical solution of the present utility model:
A kind of hydraulic pressure flat-nose pliers comprises caliper, base, regular jaw, moving jaw, moving caliper and control device, it is characterized in that: described control device comprises piston rod, hydraulic jack, hydraulic pump, overflow valve, check valve and magnetic valve; Described hydraulic jack is installed on the base, promotes the moving caliper motion by piston rod; Described piston rod connects with moving caliper by joint; Described hydraulic pump, overflow valve, check valve, magnetic valve are connected successively with hydraulic jack.
Described hydraulic pump, overflow valve, check valve, magnetic valve are installed in the inner or outside any position of milling machine.
Described magnetic valve is by the control of the knob on the knob plate.
Described knob plate is installed in milling machine lathe bed outside.
Described check valve is hydraulic control one-way valve.
The beneficial effects of the utility model:
The utility model is simple in structure, can load onto or take off workpiece easily, and is easy to use, effectively reduced labour intensity, improved production efficiency, and squeeze force is of moderate size simultaneously, improves machining accuracy.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, caliper; 2, base; 3, regular jaw; 4, moving jaw; 5, moving caliper; 6, joint; 7, piston rod; 8, hydraulic jack; 9, hydraulic pump; 10, overflow valve; 11, check valve; 12, magnetic valve; 13, button panel; 14, workpiece.
The specific embodiment
Specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of hydraulic pressure flat-nose pliers comprises caliper 1, base 2, regular jaw 3, moving jaw 4, moving caliper 5, joint 6, piston rod 7, hydraulic jack 8, hydraulic pump 9, overflow valve 10, check valve 11, magnetic valve 12, button panel 13, workpiece 14.On the caliper 1 guide rail is installed, be equipped with on the guide rail can left and right movement moving caliper 5, moving jaw 4 is fixed on the moving caliper 5.Hydraulic pump 9, overflow valve 10, check valve 11 and magnetic valve 12 are connected successively with hydraulic jack 8, can be installed in the milling machine lathe bed or outer any position, and hydraulic jack 8 is installed in base 2 rear portions, and moving caliper 5 is installed on caliper 1 guide pass; Described joint 6 one ends are fixed in moving caliper 5 end faces, and the other end is fixed on the piston rod 7, and regular jaw 3 and moving jaw 4 open the distance size and determined by joint 6 length; Described check valve 11 is hydraulic control one-way valves, during workpiece pressing, prevents the fluid reverse flow, when unclamping workpiece, opens check valve by hydraulic control, and oil stream all can be flowed at both direction.
The concrete course of work:
At first adjust the gag of caliper 1 and moving caliper 5 inside, make moving caliper 5 cooperate degree of tightness even at caliper 1 guide pass, and change suitable joint 6 according to workpiece 14 sizes.
Secondly adjust the pressure size of overflow valve 10 according to workpiece 14 wall thickness situations, the extruding force of moving jaw 4 is of moderate size, workpiece is too tightly easily damaged in extruding by pressure, squeeze not press tightly, and the workpiece fine motion, the milling precision does not reach requirement.
Press the knob that retreats on the knob plate 13 with hand again, moving jaw 4 and moving caliper 5 retreat, hand lifts the knob that retreats on the knob plate 13, moving jaw 4 and moving caliper 5 stop to retreat, be placed on caliper 1 guide pass between regular jaw 3, the moving jaw 4 with handgrip workpiece 14, workpiece is set level, press the knob that advances on the knob plate 13 with hand, moving jaw 4 and moving caliper 5 advance, hand lifts the knob that advances on the knob plate 13, moving jaw 4 and moving caliper 5 halt, and workpiece pressing 14 begins processing.
After last workpiece 14 processes, press the knob that retreats on the knob plate 13 with hand, moving jaw 4 and moving caliper 5 retreat, and hand lifts the knob that retreats on the knob plate 13, and moving jaw 4 and moving caliper 5 stop to retreat, and workpiece is removed.Wait for next working cycles.
Heavier as workpiece, available other lifting device is installed workpiece.
To sum up, the utility model produces a desired effect.
