Abstract

The invention discloses a mechanical arm drawing mechanism. The mechanical arm drawing mechanism includes a supporting platform and a lifting platform, and the lifting platform and the supporting platform are connected by a lifting mechanism. The lifting platform is provided with an upper motor and a lower motor separately, the lower motor is connected with a main arm, and the upper motor is connected with an auxiliary arm. A connecting rod is hinged to the other end of the auxiliary arm, and a working arm is hinged to the other end of the connecting rod. A pen clamp is arranged at the other end of the working arm, and the other end of the main arm is hinged to the working arm. Firstly, the defects of a steering engine are solved by means of linear compensation, curvature speed regulation,virtual compensation and graphic feedback compensation for the steering gear, and then through the cooperation of the upper motor and the lower motor, the pen clamp at the front end of the working arm can be placed at any position of a drawing board. The whole mechanical arm drawing mechanism is low in cost, simple in structure, small in size and wide in application range.

Description

technical field [0001] The invention relates to a drawing device, in particular to a drawing mechanical arm and its control system. Background technique [0002] At present, in the existing drawing devices, stepper motors are basically used. Due to the disadvantages of high cost in the use of stepper motors, low-cost steering gears are used in this scheme. However, for the low precision of the steering gear itself, the angle Defects such as imprecise control. Contents of the invention [0003] The technical task of the invention is to provide a drawing mechanical arm and its control system for the above deficiencies in the prior art. [0004] The technical solution adopted by the invention to solve its technical problems is: a drawing mechanical arm, including a supporting platform and a lifting platform, wherein the lifting platform is connected to the supporting platform through a lifting mechanism, and the lifting mechanism includes a lifting steering gear and a liftin...
