Problems solved by technology

[0004] The object of the present invention is to provide a connection device between the ball screw and the worm gear, which overcomes the defect that the positioning pin is easily stuck in the notch in the above connection device between the ball screw and the worm gear, which causes difficulty in adjustment ; Simultaneously, also in order to overcome in existing mechanism, the edge angle of locating pin is easy to gnaw off the material on the turbine that contacts with it, and the broken nitrate that causes thereby falls between ball head and ball bowl, causes between moving parts Defects of abnormal wear and tear

Abstract

Provided is a connecting device of a bulb lead screw and a worm gear. A lower ball bowl is installed at the bottom of a turbine box, a worm is installed at the position of the upper middle portion of the turbine box, a turbine is installed in a cavity of the turbine box, the turbine is correctly meshed with the worm, a locating pin is installed in a bulb blind hole of the bulb lead screw, simultaneously a joint ball is installed on the locating pin protruding out of a ball, the joint ball right faces to a notch on the turbine, the ball of the bulb lead screw penetrates through a middle hole of the turbine to be installed on a ball bowl portion of the lower ball bowl, an upper ball bowl penetrates through the upper portion of the bulb lead screw to be installed on the turbine box, a pressing and covering board is installed on the turbine box, simultaneously the pressing and covering board is fixed through a bolt, and finally a connecting rod is installed on the bulb lead screw.

Description

technical field [0001] The invention relates to a connection device, in particular to a connection device between a ball screw and a worm wheel. It belongs to the technical field of presses. 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 mutual rotation between the ball screw and the turbine. [0003] T...
