Elevating mechanism of objective table

Abstract

The invention relates to an elevating system of an objective table. The elevating system comprises a seat body and a connecting plate which can be arranged on the seat body by sliding, an air cylinder is fixedly arranged on the seat body, a piston rod arranged along the perpendicular direction is arranged on the air cylinder, the upper end and the lower end of the piston rod are respectively traveled through the air cylinder, the upper end of the piston rod is fixedly connected with the connection plate, the lower end of the piston is fixedly connected with a wedge-shaped lower inclined block, an upper inclined block which can be moved along the horizontal direction is also arranged on the seat body, a groove is arranged on the upper inclined block, the piston rod passes through the groove, the upper surface of the lower inclined block is parallel to the lower surface of the upper inclined block, the lower surface of the upper inclined block and the upper surface of the lower inclined block are respectively intersected with a plumb line, and the connecting line between the two intersection points is the stroke of the objective table; the flexible change of the stroke of the air cylinder is realized through a pair of wedge-shaped inclined blocks, and the accurate control for the stroke can be achieved through the drive of a screw rod. The elevating system has the advantages that the drive efficiency is high, the drive is accurate, the adjustment is convenient, and the stroke can be flexibly changed.

Description

technical field [0001] The invention relates to an elevating mechanism of a loading platform, which is especially suitable for use when the stroke of the loading platform is small and the stroke is flexible and changeable. Background technique [0002] When manufacturing bicycles, two rows of holes are usually processed on the front and rear rims of the bicycle to install bicycle spokes; since the distance difference between the two rows of holes in the axial direction of the rim is very small, in the prior art, ordinary cylinders are used The transmission is imprecise; in addition, for the rims of different specifications, the distance between the two rows of holes is also different, and the original equipment cannot be flexibly adjusted according to the processing requirements. Contents of the invention [0003] The object of the present invention is to provide a loading platform elevator with precise transmission and flexible stroke. [0004] drop mechanism. [0005] ...
