Novel connecting mechanism of ball screw rod and worm wheel of press machine

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 [0001] The invention relates to a connection mechanism between a ball screw and a turbine, in particular to a novel connection mechanism between a ball screw and a turbine for a press. It belongs to the technical field of press equipment. Background technique [0002] At present, in some medium, large and high-end press products, the closed height adjustment of the slider adopts the method of motorized adjustment, that is, the worm rod driven by the motor is used, the worm rod drives the turbine, and the turbine drives the ball screw in the continuous The internal thread of the rod is rotated to adjust the closing height of the slider. In the above-mentioned mechanism connection, a hole perpendicular to the axis of the ball screw is drilled on the ball head, and a positioning pin is installed in the hole. There is a notch on the edge of the inner hole of the turbine, and the protruding part of the positioning pin is stuck in the notch, so as to limit the mut...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of connection mechanism between the ball screw and the turbine of the press, to overcome the problem that the positioning pin is easily stuck in the gap in the existing connection mechanism between the ball screw and the turbine, which causes At the same time, in order to overcome the existing mechanism, the edges and corners of the positioning pin are easy to gnaw off the material on the turbine that is in contact with it, and the resulting broken nitrate falls between the ball head and the ball bowl. Defects that cause abnormal wear between moving parts
