Abstract
The invention relates to a novel connecting mechanism of a ball screw rod and a worm wheel of a press machine. The novel connecting mechanism is characterized in that a lower ball bowl is arranged at the bottom of a worm wheel box body, a worm rod is arranged at the exact position of the worm wheel box body, and the worm wheel is exactly arranged in a cavity of the worm wheel box body so as to ensure that the worm wheel is exactly engaged with the worm rod; a positioning pin is arranged in a blind hole at the ball part of the ball screw rod, meanwhile, a joint ball body is arranged on the positioning pin which protrudes out of the ball head part and aligned with a gap on the worm wheel; the ball part of the ball screw rod passes through from a middle of the worm wheel and is arranged at a cup bowl part of the lower ball bowl, an upper ball bowl passes through from the upper part of the ball screw rod and is exactly arranged on the worm wheel box body; a cover plate is arranged on the worm wheel box body and simultaneously fixed by using bolts; and finally, a connecting rod is arranged on the ball screw rod.
Description
Technical field
The present invention relates to the bindiny mechanism of a kind of ball screw and turbine, the bindiny mechanism of particularly a kind of novel press machine ball screw and turbine.Belong to the press equipment technical field.
Background technology
At present, medium-and-large-sized at some, in the high-grade forcing press product, the shut height of slide block is regulated the method that all adopts motor-driven adjusting, promptly adopt by motor-operated scroll bar, scroll bar drives turbine, turbine drives ball screw and rotates in the internal thread of connecting rod, come the shut height of adjusting slider with this, wherein in above-mentioned mechanism connects, on bulb, bore one with the perpendicular hole of ball screw axis, and alignment pin is installed in the hole, have breach at the edge of turbine endoporus, the outstanding position of alignment pin is stuck in the breach, limits the purpose of rotating mutually between ball screw and the turbine with this.
Above-mentioned described alignment pin is a cylindrical configuration, but, because forcing press is when work, ball screw is ceaselessly swung, and alignment pin is not only stuck easily in breach, cause and regulate difficulty, simultaneously, the corner angle of alignment pin are also gnawed with it the part material on the turbine of contact easily, and form broken nitre and fall between ball screw and the ball bowl, thereby cause the wearing and tearing between the moving component, reduce the service life of part.
Summary of the invention
The objective of the invention is to: the bindiny mechanism of a kind of novel press machine ball screw and turbine is provided, overcomes in the bindiny mechanism of existing ball screw and turbine, alignment pin is stuck easily in breach, the defective of the adjusting difficulty that is caused thus; Simultaneously, also be in order to overcome in the existing mechanism, the corner angle of alignment pin are gnawed the material on the turbine of contact with it easily, and the broken nitre that causes therefrom falls between bulb and the ball bowl, cause the defective of the heel and toe wear between the moving component.
For achieving the above object, the technical solution adopted in the present invention is: will play the ball bowl to be installed to the bottom of turbine casing, scroll bar is installed to the tram of turbine casing, in the cavity of turbine casing, turbine is correctly installed, guarantee turbine and scroll bar correct engagement, alignment pin is installed in the bulb blind hole of ball screw, on the alignment pin that protrudes the bulb, install the joint spheroid simultaneously, the joint spheroid is aligned breach on the turbine, the ball screw bulb is passed the ball bowl portion that is installed in down the ball bowl from the interstitial hole of turbine, last ball bowl is passed from the top of ball screw, and correctly be installed in the turbine casing above, cover clamp is installed in above the turbine casing, is fixed with bolt simultaneously.At last, connecting rod is installed to ball screw above.
Beneficial effect: because spheroid has the universal free degree in breach, so, be not easy stuck, simultaneously can not cause the phenomenon that bites to the piece surface that it contacted yet, thereby also just avoid metal fragment to have prolonged mechanical service life to the heel and toe wear phenomenon that moving component caused.
Description of drawings
Accompanying drawing 1 is a schematic diagram of the present invention.
Shown in the figure: 1, ball screw; 2, turbine; 3, alignment pin; 4, joint spheroid; 5, scroll bar; 6, following ball bowl; 7, connecting rod; 8, go up the ball bowl; 9, turbine casing; 10, cover clamp; 11, bolt; 12, bulb.
The specific embodiment
