Description
Technical field
The invention belongs to clamping tool field, especially relate to a kind of hydraulic location device.
Background technology
In existing hydraulic location device, mostly use hydraulic cylinder to drive the motion of hydraulically extensible bar directly to be located by Workpiece clamping, this device is due to the long-term pressurize of needs, hydraulic pressure is directly utilized to clamp, easily cause device feature to damage, location inaccuracy, and power consumption is large.
Summary of the invention
In view of this, the present invention is intended to propose a kind of hydraulic location device, can pressurize for a long time, accurate positioning, power consumption little.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of hydraulic location device, comprise base, hydraulic cylinder, piston, connecting rod, carriage release lever and positioning head, described base is U-shaped integrative-structure, comprise the first vertically relative vertical seat, second vertical seat and horizontal base, described hydraulic cylinder is located at first vertical upper end, described carriage release lever is horizontal through the first vertical seat, the spherical cavity of opening upwards is had in the middle part of carriage release lever, described piston vertically seals slip in hydraulic cylinder, be connected by connecting rod between piston with carriage release lever, cavity is had perpendicular to horizontal base direction between described carriage release lever and hydraulic cylinder, piston and connecting rod can move in cavity, described connecting rod is divided into first connecting rod and second connecting rod, second connecting rod is L shape, L shape bending place is hinged to be installed in cavity, first connecting rod one end and the piston hinge told, the other end and second connecting rod hinged, the second connecting rod other end is spherical shape, can move in the spherical cavity of carriage release lever.Being fixedly hinged of second connecting rod and cavity, can make the two ends of second connecting rod a little do circular motion round being fixedly hinged, and second connecting rod spherical shape one end horizontal direction produces displacement, drives carriage release lever horizontal direction to move.Carriage release lever moves horizontally in the first vertical seat, achieves the clamping of clamping device and unclamps.When first connecting rod moves to horizontal direction, second connecting rod and the hinged one end of first connecting rod are vertical direction, and now clamping device reaches and does stable state, and carriage release lever horizontal direction power cannot make first connecting rod move, now piston not easily moves, and the pressure caused hydraulic cylinder is also smaller.
Further, the inner side of the described second vertical seat and carriage release lever are near second vertical one end, and bolt is connected with positioning head respectively, and two positioning head shapes are the same.Positioning head is oppositely arranged, and is put between the two by positioning workpieces.
Further, the cross section of described positioning head is V-shaped, rectangle or semicircular arc.Expand the scope of application of fixture.
Further, described carriage release lever is cylindric.Carriage release lever can move horizontally.
Relative to prior art, hydraulic location device of the present invention has following advantage:
Hydraulic location device of the present invention, by connecting rod and the connection between piston and carriage release lever, is converted into the power moved horizontally by the power of hydraulic pressure vertical direction, realize maximum grip function and be not easily open, accurate positioning, when unclamping positioning workpieces, piston upwards, consumes energy little; Different positioning heads can be changed, expansion instrument range of application.
