Abstract
The invention discloses a synchronous clamping device driven by a floating single cylinder, belonging to the technical field of fixture design. The synchronous clamping device comprises a casing, a hydraulic cylinder, two sector gears, two hinge pins and two jaws, wherein the hydraulic cylinder is arranged in the casing, and the two jaws extend out of the casing; the two sector gears and the two jaws are respectively fixed on the two hinge pins; the two sector gears are mutually meshed; the two hinge pins are respectively installed on the casing; the diameter of the hinge pin is smaller than that of an axle hole, in which the hinge pin is arranged, on the casing; the piston of the hydraulic cylinder is hinged with the jaw through which the hinge pin passes; and the two jaws are clamped and released by changing the direction of pressure oil in the hydraulic cylinder. The invention adopts the sector gear for meshing transmission and adopts the single hydraulic cylinder for driving, and the rotation direction of the gear is changed by changing the direction of the pressure oil so as to clamp and release the jaws. The diameter of the axle hole for installing the hinge pin is more than that of the hinge pin; and when the jaws clamp an anchor rod and if the clamping force of the jaws on two sides is unequal, the hinge pin can be subject to floating adjustment in the axle hole so as to solve the problem of asymmetrical clamping force.
Description
Technical field
The invention belongs to the technical field of jig Design, particularly relate to a kind of floating type single hydraulic oil cylinder driving synchronous clamping device that is applied to jumbolter, be used for clamping the operation of anchor pole, dead man.
Background technology
At present, in the anchor pole clamping device of jumbolter, most Driven by Hydraulic Cylinder modes that adopt, general employing four or two hydraulic cylinders, hydraulic cylinder symmetry bolt shaft line position level is installed, and the axis of the axis of hydraulic cylinder and anchor pole is perpendicular, move by the pressure oil piston rod, piston rod links to each other with claw, under the effect of pressure oil, the clamping that two of symmetry or four claws can be realized anchor pole with loosen.This clamping device does not have middle force transmission mechanism, and the drive member piston rod directly links to each other with claw, and is simple in structure, but cost is higher, and when jumbolter clamped the anchor pole dead man, the clamping force size that the both sides claw acts on the anchor pole may be unequal, influences operation.
Summary of the invention
At the technical problem of above-mentioned existence, the invention provides a kind of floating type single hydraulic oil cylinder driving synchronous clamping device, it is to adopt single Driven by Hydraulic Cylinder, use the gear force transmission mechanism, simple in structure, when clamping anchor pole, can float, solved the asymmetric problem of clamping force, and cost is low.
Technical scheme of the present invention is as follows:
A kind of floating type single hydraulic oil cylinder driving synchronous clamping device, comprise housing, place hydraulic cylinder, two sector gears, two bearing pins in the housing and stretch out two outer claws of housing, described two sector gears and two claws are separately fixed on two bearing pins, and two sector gears are meshing with each other, two bearing pins are installed in respectively on the housing, and described pin diameter is less than the shaft hole diameter that this bearing pin is installed on the housing.The piston of hydraulic cylinder is hinged with the claw that wherein passes bearing pin, the clamping that realizes two claws by the direction that changes cylinder pressure oil with loosen.
The central angle of described two sector gears is identical, is 120 °-180 °.Described pin diameter is than the little 2-3mm of shaft hole diameter.
Beneficial effect of the present invention is:
The present invention adopts the sector gear engaged transmission, makes the swing of gear driven claw.The employing single hydraulic cylinder drives, and can realize that by the direction that changes pressure oil the rotation direction of gear changes, thus the clamping that realizes claw with loosen.The shaft hole diameter of the installation bearing pin that the present invention processes on housing is greater than pin diameter, when claw of the present invention is clamped anchor pole, if the claw clamping force of both sides is unequal, the then bearing pin adjustment of can in axis hole, floating, till the clamping force equal and opposite in direction, so just solved the asymmetric problem of clamping force.
