Apparatus and method for positioning polar coordinate controlled by computer

Abstract

The invention discloses a computer-controlled polar coordinate location device and a method. The invention is characterized in that the internal ring of a bearing is connected with one end of a precision positioning screw rod; an angle displacement execution stepping motor is arranged and executes the quantitative angular displacement motion of the bearing under the control of a computer to drive the positioning screw rod connected therewith to have the same motion; a screw rod rotation stepping motor is connected with the bearing and a supporter, wherein the shaft of the motor is connected with the precision positioning screw rod; the screw rod rotation stepping motor executes the quantitative rotation of the positioning screw rod under the control of the computer, resulting in the quantitative motion of a screw nut on the positioning screw rod in the two coordinates; and the screw nut is provided thereon with a machining tool. The invention has the advantages that: the invention solves the problem of automation of marking-out operation in fitters, is applicable for the use in changeable places, and is convenient to carry.

Description

Technical field [0001] The invention belongs to the field of automatic control, and relates to a portable automatic processing device and method with a wide range of use, and in particular to a computer-controlled polar coordinate positioning device and method. Background technique [0002] The current machining positioning methods all work in the XY plane coordinate mode, such as the positioning of a variety of processing machine tools and the positioning of the engraving machine. Its characteristic is that the positioning coordinate axis is fixedly installed in the X and Y directions to form a working plane. It must be used in a fixed site, and the work surface that can be operated is limited. Its shortcomings: on the one hand, the structure cannot be changed at any time and is easy to carry; on the other hand, the processed parts must be placed on a limited processing platform. [0003] In some special applications, such as portable engraving machines used in the field, the eq...

Its disadvantages: on the one hand, the structure cannot be changed at any time and it is easy to carry; on the other hand, the processed parts must be placed on a limited processing platform

Another example is the line marking work of the fitter. Sometimes the workpiece needs to be placed flat, sometimes it needs to be placed upright, and sometimes the workpiece may be too large to be placed on a fixed platform, etc. X-Y plane coordinate positioning cannot meet the needs of these occasions.
