Connecting rod lifting and overturning device based on differential screw transmission and rocker slider transmission

Abstract

The invention relates to a connecting rod lifting and overturning device based on differential screw transmission and rocker slider transmission. The device is characterized in that the center of a differential screw penetrates through a lead screw axle base, two ends of the differential screw are matched and assembled with a left bearing assembly and a right bearing assembly, and a left thread section and a right thread section of the differential screw are screwed into a left drive nut and a right drive nut respectively to form a differential screw mechanism; upper table-boards of lifting slide guide rails and lower table-boards of sliders are matched and assembled; shaft assemblies are connected with the sliders and an overturning frame, one end of each overturning connecting rod is fixed with the overturning frame, and the other end is fixed or separated from with support frames through fixing pin shafts and pin clamp plates; connecting rods, the sliders and the support frames constitute a rocker slider mechanism I, and rockers swing to drive the sliders to move up and down along the lifting slide guide rails; the sliders, the overturning frame, the overturning connecting rods and the support frames constitute a rocker slider mechanism II, and the sliders linearly move up and down to drive the overturning frame to perform overturning movement. The connecting rod lifting and overturning device based on differential screw transmission and rocker slider transmission has lifting and overturning functions simultaneously, is more compact in structure, convenient to operate and good in stability, and saves confined space.

Description

technical field [0001] The invention belongs to the field of precision machinery, and in particular relates to a connecting rod lifting and turning device based on differential screw transmission and rocker slider transmission. Background technique [0002] At present, most of the lifting and turning devices realize the lifting and turning functions through different mechanical structures, that is, each function needs to be given an active force, so there are problems such as complex structure, poor stability, slow lifting speed, inconvenient operation, and high manufacturing cost. However, in a limited space, there is no report on a device that uses the differential principle and the planar four-bar principle to integrate the two functions of lifting and turning, and is stable and self-locking in place. Contents of the invention [0003] In order to solve the problems of the prior art, the purpose of the present invention is to find a device that can quickly lift and turn...
