In view of the above existing problems in the prior art, the present invention provides a kind of general spring fixtures of processing pipeloop class, fit
For the processing of mass pipeloop class workpiece, while ensureing the processing quality and precision of workpiece, improve production efficiency, reduces labour
Intensity.
The technical solution that the present invention realizes is as follows, a kind of general spring fixture of processing pipeloop class, including drive system and
Chuck body, chuck body include plug screw pull rod, shell, collet and locating ring, the spiral shell in drive system and chuck body
It fills in pull rod to be connected, plug screw pull rod inner cavity is sleeved in positioning ring seat, and one end of plug screw pull rod is equipped with hexagon socket head cap screw, the other end
Outer end is connected with collet by screw thread, and shell is sleeved on the outside of positioning ring seat and collet, and workpiece passes through interior hexagonal
Screw is fixed in locating ring, and one end of collet slots and is equipped with taper, and inner walls are with collet contact site
The conical surface.
Further, the drive system is fluid power system, including quantitative hydraulic pump, motor, pressure switch, electricity
Magnetic check valve and 2/2-way reversal valve, motor are connected with quantitative hydraulic pump, and quantitative hydraulic pump is unidirectional by electromagnetism by hydraulic oil
Valve, check valve are connected with hydraulic cylinder, and 2/2-way reversal valve in parallel, pressure switch two are connected to quantitative hydraulic pump on hydraulic cylinder
On oil circuit between electromagnetism check valve, pressure switch one is connected on the oil circuit between electromagnetism check valve and hydraulic cylinder.
Further, it is connected with pressure gauge on pressure switch two.
Further, it is connected with throttle valve between 2/2-way reversal valve and hydraulic cylinder.
Pump motor starts, and the electromagnet of electromagnetism check valve do not work, and does not give hydraulic pressure oil supply cylinder, until pressure reach pressure after
The upper limit that electric appliance one is set, pressure switch two send out signal and open electromagnetism check valve, and system starts, to hydraulic pressure oil supply cylinder, to push
Hydraulic cylinder piston piston rod is retracted, and piston rod is connected by connecting rod with the plug screw pull rod in chuck body, to drive plug screw to draw
Bar moves, and while plug screw pull rod is moved to the left, drives collet to be moved to the left, since collet end is slotted and is equipped with
Taper is simultaneously tightened with the effect of the taper of tapered shell, to realize the self-centering clamping workpiece to workpiece.Due to electricity
The single effect of magnet valve, fixture are in system packing state；When pressure is down to one preset lower limit of pressure switch, pressure after
Electric appliance one sends out signal, starts motor and gives system ftercompction；2/2-way reversal valve is opened when fixture loosens, and connects right position, hydraulic pressure
Cylinder is connected to fuel tank carries out pressure release, and hydraulic cylinder is spring reset hydraulic cylinder, therefore automatically resets and unclamp workpiece.
This clamp structure is simple, manufacture is easy, is easy to operate；Using hydraulic system as clamping force, may be implemented electrodeless
Pressure regulation, while hydraulic system is swift in response, and can facilitate automated production；Fixture, which has, makes heart function by oneself, without repeatedly to arriving,
Once to after just, it is only necessary to which clamping workpiece ensure that Workpiece Machining Accuracy.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the vertical view of Fig. 1.
