Abstract
Provided is a novel rocker arm lifting device. A column is connected onto a base and fixed through a fastening bolt, a cylinder body is arranged at the middle position of the column, and a piston is installed in the cylinder body. A piston rod is installed at the middle position of the piston, a cylinder cover is installed at the upper opening portion of the cylinder body by using a bolt after the piston rod penetrates a middle hole of the cylinder cover, and a cross beam is fixed at the end portion of the piston rod by using a locking nut. One end of a double-body pulling rod is fixed with the cross beam, the other end of the double-body pulling rod is fixed with a rocker arm, and the double-body pulling rod is installed between the cross beam and the rocker arm symmetrically. Due to the fact that the double-body pulling rod is installed between the cross beam and the rocker arm symmetrically, eccentric torque produced by the rocker arm during movement is reduced to the minimum extent, and the novel rocker arm lifting device has the advantages that the lifting device is small in eccentric torque, little in lead screw abrasion and long in service life, and a lead screw is not easily broken off.
Description
Technical field
The present invention relates to a kind of radial up-down device, particularly a kind of Novel remote arm elevator apparatus, belong to the machine tool technical field.
Background technology
The radial up-down device is the critical function parts of lathe production and processing, the structure of parts is comprised of motor, reduction box, leading screw etc., its major function is rotatablely moving after reduction box slows down of motor, the rotation of driving leading screw, because leading screw is connected with rocking arm, so just drive rocking arm, do rising or descending motion; Because rocker structure is the constructional device of single armed, the eccentric moment that rocking arm produces is very large, so existing radial up-down device exists eccentric moment and greatly, easily causes the leading screw wearing and tearing and fracture, reduce the lowering or hoisting gear defect in service life.
Summary of the invention
The object of the invention is to: provide that a kind of eccentric moment is little, the leading screw wearing and tearing less, a kind of Novel remote arm elevator apparatus of frangibility leading screw, lowering or hoisting gear long service life not, overcome existing radial up-down device because rocking arm is that the existing eccentric moment of single arm structure is large, easily cause the leading screw wearing and tearing and fracture, reduce the lowering or hoisting gear defect in service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Novel remote arm elevator apparatus, it is by base, fastening bolt, column, rocking arm, the binary pull bar, piston rod, crossbeam, locking nut, cylinder body, piston, cylinder cap forms, be connected with column on base, column is fixed by fastening bolt, centre position at column is provided with cylinder body, piston is installed in cylinder body, piston rod is arranged on the middle part of piston, piston rod is through after the interstitial hole of cylinder cap, with bolt, cylinder cap is arranged on to the upper oral part of cylinder body, crossbeam is fixed on the end of piston rod with locking nut, one end and the crossbeam of binary pull bar are fixed, an other end and rocking arm fix, the symmetrical binary pull bar that is equipped with between crossbeam and rocking arm.
Beneficial effect: because the present invention has adopted in the cylinder body at binary pull bar and piston two ends injection pressure oil respectively, just can driven plunger move up and down, thereby realize the oscilaltion campaign of rocking arm, owing to being provided with the binary pull bar, be arranged on symmetrically between crossbeam and rocking arm, so, the eccentric moment that rocking arm is produced at the volley is reduced to minimum level, make whole radial up-down device there is eccentric moment little, the leading screw wearing and tearing are few, frangibility leading screw not, the advantage of lowering or hoisting gear long service life, reached purpose of the present invention, effectively overcome existing radial up-down device because rocker structure is that the existing eccentric moment of single arm structure is large, easily cause the leading screw wearing and tearing and fracture, reduce the lowering or hoisting gear defect in service life.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present invention is described further.
Fig. 1 is structure principle chart of the present invention.
Shown in figure: 1, base; 2, fastening bolt; 3, column; 4, rocking arm; 5, binary pull bar; 6, piston rod; 7, crossbeam; 8, locking nut; 9, cylinder body; 10, piston; 11, cylinder cap.
The specific embodiment
The radial up-down device has a base (1), be connected with column (3) on base (1), column (3) is fixing by fastening bolt (2), be provided with cylinder body (9) in the centre position of column (3), piston (10) is installed in cylinder body (9), piston rod (6) is arranged on the middle part of piston (10), piston rod (6) is through after the interstitial hole of cylinder cap (11), with bolt, cylinder cap (11) is arranged on to the upper oral part of cylinder body (9), crossbeam (7) is fixed on the end of piston rod (6) with locking nut (8), one end of binary pull bar (5) and crossbeam (7) are fixing, an other end and rocking arm (4) fix, the symmetrical binary pull bar (5) that is equipped with between crossbeam (7) and rocking arm (4).
