Abstract
The invention discloses a novel rocker arm lifting device of a drill press, and the novel rocker arm lifting device comprises an upright column, a rocker arm, screw rods, a reduction box, screw rod nuts and a motor. The screw rods are respectively arranged at the two corresponding sides of the upright column of the drill press in a manner that the screw rods are coaxial with the upright column. With the structure with two corresponding screw rods, the rocker arm lifting deice has strong action for resisting the eccentric torque caused by the rocker arm, so the screw rods are not easy to wear down or break up.
Description
Technical field
The present invention relates to a kind of drilling machine rocking arm lowering or hoisting gear, particularly a kind of novel drilling machine rocking arm lowering or hoisting gear belongs to the machine tool technology field.
Background technology
So far; Mostly the rocking arm of drilling machine is done the vertical direction adjustment under the effect of single leading screw on its vertical shaft elevating mechanism is to be made up of motor, reduction box, leading screw, and the rotation of motor drives the rising or the decline of drilling machine rocking arm through the rotation of reduction box deceleration leading screw; At present; Mostly the rocking arm of drilling machine is the structure of a beam type; So rocking arm can produce certain eccentric moment and be carried in above the single leading screw of its column; Therefore, single leading screw is resisted the weak leading screw wearing and tearing on the column or the problem that fractures of causing easily of ability of rocking arm eccentric moment on this column, brings passive in the work easily like this.
Summary of the invention
The objective of the invention is to: a kind of novel drilling machine rocking arm lowering or hoisting gear is provided, and it can improve leading screw easy abrasion that the eccentric moment of present rocking arm causes or the passive problem that fractures effectively, thereby can bring the facility in the work.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of novel drilling machine rocking arm lowering or hoisting gear, and it is made up of column, rocking arm, leading screw, reduction box, feed screw nut and motor; It is respectively arranged with the leading screw with the column concentric in the two opposite sides of drilling machine column, and the structure of the mariages thick stick of this correspondence has the effect of resisting the eccentric moment that rocking arm produces more by force, and therefore, leading screw is not easy to occur the problem of wearing and tearing or fractureing.
Beneficial effect: the structure of mariages thick stick of the present invention, the effect of resisting the eccentric moment that rocking arm produces is more by force arranged, so leading screw is not easy to occur the problem of wearing and tearing or fractureing, therefore, result of use is good.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Fig. 1 is a structural representation of the present invention.
Shown in the figure: 1 column; 2 rocking arms; 3 leading screws; 4 reduction boxes; 5 feed screw nuts; 6 motors.
The specific embodiment
It is made up of column 1, rocking arm 2, leading screw 3, reduction box 4, feed screw nut 5 and motor 6; It is respectively arranged with the leading screw 3 with column 1 concentric in drilling machine column 1 two opposite sides, and the structure of this corresponding mariages thick stick 3 has the effect of resisting the eccentric moment that rocking arm 2 produces more by force, and therefore, leading screw 3 is not easy to occur the problem of wearing and tearing or fractureing.
