Robot arm

Abstract

The invention relates to a robot arm. The robot arm comprises a linear motor A, a base, a bearing, a supporting rod, a motor, a gear, a linear motor B, a clamping plate, a claw A and a claw B, whereinthe base is arranged at the bottom of the linear motor A; the end of a shaft of the linear motor A is rotatably connected to one end of the supporting rod by a bearing; a gear groove is formed in theinner side of the bearing; the motor is arranged at the inner side of the end of the shaft of the linear motor A; the gear is arranged on a rotating shaft of the motor and is meshed with the gear groove; the linear motor B is arranged at the other end of the supporting rod; the clamping plate passes through a shaft of the linear motor B and is fixed to the linear motor B; screw grooves A are formed in one ends of the claw A and the claw B; the claw A and the claw B are symmetrically arranged and are in pin connection with the clamping plate; a screw groove B is formed in the shaft of the linear motor B; and the screw grooves A are meshed with the screw groove B. The robot arm has the beneficial effects that the robot arm is simple in structure and convenient to operate and solves the problems that a traditional mechanical arm is complicated and inflexible, needs relatively large extension space and is difficult to overhaul due to heaviness.

Description

technical field [0001] The invention relates to the field of mechanical fixtures, in particular to a robot arm. Background technique [0002] At present, the application of mechanical arms is becoming more and more extensive, but the traditional mechanical arms are complex and not flexible enough, requiring a large space for expansion and contraction, and the mechanical arms are heavy and difficult to overhaul; mechanical claws are generally driven by motors or cylinders, and the mechanical claws driven by cylinders are removed. After that, it is difficult to maintain the clamped state. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a robot arm, which solves the problems that the traditional robot arm is complicated and not flexible enough, requires a large space for expansion and contraction, and is heavy and difficult to maintain. [0004] The technical scheme that the present invention adopts for solving th...
