Abstract

The invention discloses a parallel coordinate measuring machine controller, and belongs to controller technologies of high-precision and intelligent measurement and control instruments in the precise manufacturing field. A Clipper motion controller card and an industrial control mechanism are adopted to from an open structure, and a speed-position double closed loop control principle is adopted. An upper industrial personal computer is connected with the Clipper card through a network cable; an upper computer is connected with a touch display screen to achieve touch and display. An ACC-1P expansion card is connected with the Clipper card through a PC104 bus in a case of a lower computer to control a parallel coordinate measuring machine with three to eight drive rods adopted. An interface card is connected with the Clipper card and the ACC-1P card through flexible printed boards to achieve optoelectronic isolation of digital signal transmission between external equipment and the Clipper and ACC-1P cards and analog quantity transmission transfer. A handle and a direct-current servo driver are connected with the interface card. The parallel coordinate measuring machine controller is used for carrying out logic control on motion and digital quantity of the parallel coordinate measuring machine and has four measurement modes.

Description

Technical field [0001] The invention relates to a parallel coordinate measuring machine controller, in particular to an open parallel coordinate measuring machine controller in the form of a motion control card and an upper and lower computer. It belongs to the controller technology of high-precision measurement and control instruments in the field of precision manufacturing. The controller is applied to the measuring machine of parallel mechanical structure to realize high-precision micron-level size and shape tolerance measurement, and is an important measuring instrument in precision manufacturing and reverse engineering. The controller can control the spatial movement of the measuring head in four ways, including handle follow-up, touch screen touch, programming automatic control, and self-learning control, to realize coordinate measurement. Background technique [0002] Coordinate Measuring Machine CMM (Coordinate Measuring Machine) is a high-precision, intelligent mea...
