Multidirectional synchronous telescopic and vertical lifting composite motion driving device

Abstract

The invention discloses a multidirectional synchronous telescopic and vertical lifting composite motion driving device. The composite motion driving device is divided into an upper layer and a lower layer, wherein the upper layer is provided with a conical rope spiral groove rope transmission mechanism and a lifting mechanism, and the lower layer is provided with an Archimedes spiral groove multidirectional synchronous telescopic mechanism. The composite motion driving device is characterized in that rotary motion of a motor is converted into spiral motion and lifting motion; the spiral motion of the upper layer is converted into multidirectional synchronous telescopic motion at the same time at the lower layer; and the upper layer comprises an upper spiral disc and a mechanism above the upper spiral disc, and the lower layer mechanism comprises a lower spiral disc and a mechanism below the lower spiral disc. The composite motion driving device solves the problems that in the prior art, an electric chuck and a butt joint mechanism cannot achieve multidirectional synchronous telescopic and vertical lifting composite motion, an accurate transmission proportional relation of synchronous telescopic and vertical lifting cannot be established, gear transmission is adopted for various chucks, the mechanism is bloated, the weight is great, the transmission efficiency is low, the motion range is limited, and light weight cannot be achieved.

Description

technical field [0001] The invention belongs to the technical field of compound motion driving devices, and in particular relates to a multi-directional synchronous telescopic and vertical lifting compound motion driving device. Background technique [0002] Simple motion can only realize one motor to drive one action, and compound motion can realize one motor to drive multiple actions to move simultaneously, thus realizing multi-mechanism synchronous motion. [0003] A chuck is a mechanical device used to clamp a workpiece on a machine tool. A machine tool accessory that clamps and positions workpieces by using the radial movement of movable jaws evenly distributed on the chuck body. The chuck is generally composed of three parts: the chuck body, the movable jaw and the jaw driving mechanism. The minimum diameter of the chuck body is 65mm, and the maximum can reach 1500mm. There is a through hole in the center to pass the workpiece or bar; the back has a cylindrical or sh...

AI Technical Summary

Problems solved by technology

[0004] At present, various electric chucks and docking mechanisms can convert motor drive into multi-directional linear motion. However, these electric chucks and docking mechanisms cannot realize multi-directional synchronous expansion and vertical lifting compound motion, nor can they establish synchronous expansion and vertical lifting. Due to the gear transmission of various chucks, the mechanism is bloated, the weight is large, the transmission efficiency is low, and the range of motion is limited, so it is impossible to achieve light weight, high-efficiency transmission, and large-scale motion.
