Abstract
The invention discloses a drilling machine rocker arm elevator mechanism driven by double screws. The top of a stand column is provided with a rotatable reduction gearbox provided with two same output shafts, the relative positions of the two same output shafts on the reduction gearbox are mutually symmetrical, a feed screw nut is installed and fixed at a proper position on the rocker arm, one end of a screw rod is fixedly connected with the output shafts of the reduction gearbox, and the other end of the screw rod is screwed and installed in the feed screw nut on the rocker arm to correctly connect a motor with the reduction gearbox.
Description
Technical field
The present invention relates to a kind of drilling machine rocking arm elevating mechanism, the drilling machine rocking arm elevating mechanism that particularly a kind of mariages thick stick drives belongs to the machine tool technology field.
Background technology
At present, the rocking arm elevating mechanism of radial drilling machine is made up of motor, reduction box and leading screw, after the process reduction box that rotatablely moves of motor slows down, the rotation of driving leading screw, because leading screw links to each other with the rocking arm of drilling machine, so, just drive rocking arm and do the motion of rising or descending; Because rocking arm is the structure of a beam type; rocking arm can produce certain eccentric moment; this eccentric moment also be carried in simultaneously leading screw above; so; leading screw is the wearing and tearing even the danger that can fracture easily not only, and is same, because the existence of eccentric moment; what also can cause rocking arm and column cooperates wearing and tearing easily between the sliding surface, the service life of reduction lathe.
Summary of the invention
The objective of the invention is to: the drilling machine rocking arm elevating mechanism that provides a kind of mariages thick stick to drive, this elevating mechanism can make rocking arm when lifting the eccentric moment that rocking arm produced is reduced to minimum level, overcome eccentric moment and make the leading screw wearing and tearing even the defective that can fracture easily, also be in order to overcome the existence of eccentric moment simultaneously, can cause rocking arm and cooperating between the sliding surface of column to be worn and torn easily, reduce the defective that lathe uses the longevity.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a rotatable reduction box is installed on the top of column, reduction box has two identical output shafts, and the relative position of two identical output shafts on reduction box be symmetry each other, feed screw nut is fixed on the appropriate location of rocking arm, one end of screw mandrel is fixedlyed connected with the output shaft of reduction box, certain in addition screw-in in the feed screw nut who is installed on the rocking arm correctly is connected motor with reduction box.
Beneficial effect: the present invention is because the screw mandrel that uses two symmetries to install drives the rocking arm lifting simultaneously, so, the eccentric moment that rocking arm produced is reduced to minimum level, overcome eccentric moment and make the leading screw wearing and tearing even the defective that can fracture easily, also be in order to overcome the existence of eccentric moment simultaneously, can cause rocking arm and cooperating between the sliding surface of column to be worn and torn easily, reduce the defective in the use longevity of lathe.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Accompanying drawing is a schematic diagram of the present invention.
Shown in the figure: 1, column; 2, rocking arm; 3, screw mandrel; 4, reduction box; 5, feed screw nut; 6, motor.
The specific embodiment
One rotatable reduction box (4) is installed on the top of column (1), reduction box (4) has two identical output shafts, and the relative position of two identical output shafts on reduction box (4) be symmetry each other, feed screw nut (5) is fixed on the appropriate location of rocking arm (2), one end of screw mandrel (3) is fixedlyed connected with the output shaft of reduction box (4), certain in addition screw-in in the feed screw nut (5) who is installed on the rocking arm (2) correctly is connected motor (6) with reduction box.
Claims (1)
1. the drilling machine rocking arm elevating mechanism that drives of a mariages thick stick, it is characterized in that: a rotatable reduction box (4) is installed on the top of column (1), reduction box (4) has two identical output shafts, and the relative position of two identical output shafts on reduction box (4) be symmetry each other, feed screw nut (5) is fixed on the appropriate location of rocking arm (2), one end of screw mandrel (3) is fixedlyed connected with the output shaft of reduction box (4), certain in addition screw-in in the feed screw nut (5) who is installed on the rocking arm (2) correctly is connected motor (6) with reduction box.
