Pass, briquetting, releasing location switch, fine work stopper rod, hydraulic fluid port A, piston, hydraulic fluid port B and heavy manual labour stopper rod；Front end housing and back cylinder cover are arranged on
The two ends of cylinder barrel, piston is located in cylinder barrel, one end connection fine work stopper rod of piston, and the end of fine work stopper rod is provided with briquetting, in pressure
The fix in position that is respectively equipped with up and down of block switchs and releases location switch, and fix in position switch and releasing location switch are used and misplaced
Distribution mode, wherein fix in position switch releases location switch away from cylinder barrel near cylinder barrel；The other end connection heavy manual labour of piston
Stopper rod, end and the authority match of heavy manual labour stopper rod are used for fixed mechanism, and hydraulic fluid port A and hydraulic fluid port B is located on cylinder barrel and is distributed in piston
Both sides.
Sealing ring and guidance tape are mounted between piston and front end housing, piston and back cylinder cover.
Dust ring is installed on front end housing and back cylinder cover.
Front end housing and back cylinder cover use high-abrasive material copper or copper alloy.
Beneficial effect
A kind of hydraulic cylinder for fixed mechanism proposed by the present invention, with high accuracy, operability is convenient, meets fixed machine
The need for structure, have the beneficial effect that：
1st, by hydraulic cylinder piston rod insertion motion correspondence hole position, for fixing and releasing fixed mechanism.
2nd, hydraulic cylinder is done into rod in pairs, wherein one end is used for fixed mechanism, and the other end is used to switch consolidating for decision mechanism
Determine state.
3rd, switch bracket is fixed on the tail end of hydraulic cylinder, two switches installed above, for judging and output mechanism
Stationary state.
4th, front end housing and back cylinder cover used and coordinated using small―gap suture between high-abrasive material copper or copper alloy, with piston rod,
So as to control fixed precision.

Specific embodiment
In conjunction with embodiment, accompanying drawing, the invention will be further described：
This hydraulic cylinder includes front end housing 1, mounting flange 2, cylinder barrel 3, back cylinder cover 4, fix in position switch 5, briquetting 6, releasing
Location switch 7, switch bracket 8, fine work stopper rod 9, hydraulic fluid port A10, piston 11, hydraulic fluid port B12, heavy manual labour stopper rod 13, dust ring 14, sealing
Circle 15 and guidance tape 16；
There is fine work stopper rod 9 one end of piston 11, and the other end has heavy manual labour stopper rod 13, and front end housing 1 and back cylinder cover 4 are pacified by screw thread
On cylinder barrel 3, piston 11 can only be moved between front end housing 1 and back cylinder cover 4.Piston 11, front end housing 1 and back cylinder cover 4 are pacified
Ensure that hydraulic oil will not be revealed equipped with sealing ring 15.Simultaneously in order to bear side force, they are equipped with guidance tape 16 above.Preceding cylinder
Lid 1 and back cylinder cover 4 are provided with dust ring 14, are to protect sealing ring 15 not destroyed by dust.
Switch bracket 8 is arranged on cylinder barrel 3 by screw, is fitted with fix in position switch 5 and is released location switch 7,
It is respectively intended to judge the fix in position state or the state in place that unlocks of hydraulic cylinder.
Briquetting 6 be located at fine work stopper rod 9 end, with the side-to-side movement of piston 11, its respectively with fix in position switch 5 and
Location switch 7 is released to contact.For compressing switch, so as to judge hydraulic cylinder state.
This hydraulic cylinder is fixed on mechanism's geo-stationary part by mounting flange 2, when mechanism kinematic to the position for needing fixation
When putting, in the interposer respective aperture of hydraulic cylinder heavy manual labour stopper rod 13, so that fixed mechanism.When mechanism needs to release fixed motion,
Heavy manual labour stopper rod 13 is fully retracted from mechanism, so as to release fixed mechanism.
Shown in Fig. 2, turned right motion to hydraulic cylinder hydraulic fluid port A plus-pressures oily piston 11, heavy manual labour stopper rod 13 is toward overhanging insertion machine
