Extension-type mechanical device

Abstract

A telescopic mechanical device, the mechanical arm includes a telescopic chain, a synchronous belt, a terminator, a support turntable, a support nozzle, a worm, and a motor. The synchronous belt is located on the upper part of the telescopic chain, the head end of the synchronous belt is fixed on the chain head, and the synchronous belt meshes with the tooth-shaped groove on the upper part of the chain link, so that the two adjacent chain links are in close contact, and the protruding chain links form a length in turn. Variable robotic arm. The lower part of each chain link has worm gear teeth, the worm gear teeth mesh with the worm, and the lower part of the closely contacted chain link forms a continuous worm gear tooth profile, and the motor drives the worm to rotate to realize the extension or retraction of the mechanical arm along the axial direction of the worm. The synchronous belt and telescopic chain are stored in the vertical cylinder after being forcibly separated by the scraper, and the mechanical arm can rotate in the horizontal plane around the centerline of the cylinder with the supporting turntable. The invention solves the problem of long-distance expansion and contraction of the mechanical arm in a restricted space.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a retractable mechanical device. Background technique [0002] The robotic arm is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and is a machine device that realizes various functions by its own power and control capabilities. Industrial robots and other robotic arms are widely used in automated production lines. The robotic arm is generally composed of multiple rotating joints, and the joints are easy to clamp objects. Industrial robotic arms are difficult to apply in the field of service robots that are in harmony with people. Robotic arms serving humans need to meet the requirements of high safety, small footprint, and large operating space. The telescopic robotic arm of the present invention occupies a small space, has a large telescopic distance, and does not have rotating joints, so it is safe when working ...
