Robot telescopic arm

Abstract

The invention discloses a robot telescopic arm, and relates to the technical field of robots. The problem that in the prior art, the telescopic length of a robot arm is not easy to control is solved.The robot telescopic arm is characterized by comprising a fixed arm, wherein a first motor is arranged in the fixed arm; at least three sets of lead screws evenly distributed around the axis of the fixed arm are further arranged on the fixed arm; the lead screws are connected with the first motor; the first motor drives the lead screws to rotate at the same time; the lead screws are sleeved with atelescopic arm; at least three sets of lead screw holes evenly distributed around the axis of the telescopic arm are formed in the telescopic arm; the lead screws are connected with the lead screw holes; and a limiting unit for preventing the lead screws from being disengaged from the lead screw holes is arranged at the end, close to the fixed arm, of the telescopic arm. The robot arm is convenient to stretch out and draw back, and meanwhile has the beneficial effects of being small in size, controllable in telescopic length and accurate in telescopic control.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a telescopic arm of a robot. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human arm to grab, carry objects or operate tools according to a fixed program. The feature is that various expected operations can be completed through programming, and the structure and performance have both the advantages of man and robot. [0003] For example, the Chinese Patent Publication No. "CN207256225U" discloses a mechanical arm for mechanical processing that is easy to adjust, including a mechanical arm body, and the mechanical arm body includes a control frame. An extended storage tank is provided inside the frame, and an extension arm is fixedly connected to the bottom of the telescopic control arm, and the extension arm is located inside the extended storage tank. The device facilitates the extension of the ro...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a robot telescopic arm, including a fixed arm, a first motor is arranged in the fixed arm, and at least three groups of wires evenly distributed around the axis of the fixed arm are arranged on the fixed arm. The lead screw is connected to the first motor, and the first motor drives the lead screw to rotate at the same time. The lead screw is provided with a telescopic arm, and the telescopic arm is provided with at least three groups of lead screw holes evenly distributed around the axis of the telescopic arm. The rod is connected with the lead screw hole, and the end of the telescopic arm close to the fixed arm is provided with a limit unit to prevent the lead screw from detaching from the lead screw hole, so as to solve the problem that the robot arm is difficult to control the telescopic length in the prior art
