Telescopic mechanical arm

Abstract

The invention discloses a telescopic mechanical arm which is a mechanical arm. The mechanical arm comprises a telescopic chain, a synchronous belt, an end executor, a supporting turntable, a supporting nozzle, a worm and a motor; the telescopic chain is composed of a series of mutually hinged chain links and has bending unidirection property; and the synchronous belt is located at the upper part of the telescopic chain, the head end of the synchronous belt is fixedly arranged on the head of the chain, the synchronous belt is meshed with dentate grooves at the upper parts of the chain links, so that the two adjacent chain links are in tight contact, and the extending chain links sequentially form the length-variable mechanical arm. The lower part of each chain link is provided with a worm gear tooth meshed with the worm, the lower parts of the chain links which are in tight contact form a continuous worm gear tooth profile, and the mechanical arm axially extends or withdraws along the worm through the rotation of the worm, driven by the motor. The synchronous belt and the telescopic chain are stored in a vertical cylinder after being forcedly separated by a scraping plate, and the mechanical arm can rotate in a horizontal plane around the center line of the cylinder along with the supporting turntable. By using the telescopic mechanical arm, the problem that the mechanical arm cannot be telescopic within a constrained space at a long distance is solved.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a telescopic mechanical arm. 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 arou...
