Numerical control mechanical motion system

Abstract

The invention discloses a numerically controlled mechanical motion system, comprising a film changing mechanism, a focusing mechanism, a transmission mechanism, and a transmission wheel; the focusing mechanism is arranged on the base of the numerically controlled mechanical transmission mechanism of the slide projector; The transmission block that pushes the mechanism to drive and contact; the focusing mechanism is installed on the upper part of the worm; the motor and the transmission wheel are coaxial; the disc changing mechanism and the friction wheel are connected through a drive shaft; A mounting groove is provided on the mechanism; the piston rod is arranged inside the focusing mechanism; a dust-proof ring is arranged on the right side of the transmission wheel and the lens barrel. The invention has the advantages of simple structure, reasonable design, long service life and low cost, and can satisfy users to display high-quality documents and videos conveniently and quickly.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a numerically controlled mechanical motion system. Background technique [0002] At present, my country's projection equipment is developing rapidly, and there are many kinds of projection equipment, but there are still many problems. The mechanical transmission of large-scale projection equipment is an indispensable work, and most of the mechanical transmission is manually operated by the operator. equipment, but the accuracy of adjustment is limited, the sensitivity is low, the degree of transmission is difficult to control, the degree of stability is low, the ability to grasp the space is relatively low, the controllable range of adjustment is relatively small, the operability is very limited, the degree of automation is low, and the simultaneous operation The slide projector operated by the operator is also quite hard.
