Short-distance plane cam type lifting device of printing working table

Abstract

The invention discloses a short-distance plane cam type lifting device of a printing working table. The short-distance plane cam type lifting device mainly comprises a working table board, a traction table board, a rack table board and a lifting mechanism, wherein a ramp guide block is fixed on the working table board; a ramp guide slot is formed in the traction table board, and the traction table board can linearly reciprocate; and the lifting mechanism is connected with the rack table board and the working table board. When a driving mechanism drives a transmission mechanism to drive the traction table board to move on the rack table board, the ramp guide slot and the ramp guide block are interacted, and a guide post of the lifting mechanism can perpendicularly ascend and descend relative to a guide sleeve, so that the working table board can move upward and downward. The lifting device is applicable to high-accuracy fine adjustment of the upward and downward movement of the working table, and adopts a plane cam structure, so that the lifting device is simple and compact in structure and convenient to design; the operating space occupied by a conventional fine adjustment device is not required; and when a crank handle is used for driving and pulling a screw rod to perform transmission, the cost can be reduced, the operation is easy, and the failure rate is low.

Description

technical field [0001] The invention belongs to the field of printing equipment, and in particular relates to a worktable lift mechanism of printing equipment. Background technique [0002] At present, the workbench (mobile workbench) used in the printing equipment industry is multi-axially movable, which is expensive, complicated in design, and requires high professional knowledge of operators and designers. Among the existing lifting devices for printing tables, the common ones are high manufacturing costs and complex design structures. For example, the fine-tuning device for the design machine takes up a lot of space, and the manufacturing of the table moving mechanism uses servo motors to drive ball screws, linear guide rails or Driven by rack and pinion, but the effect cannot achieve short-distance lifting and precise positioning, and it will result in high costs and the need to write complex control programs.
