The displacement sensor bracket of height measuring mechanism is contained on aluminium section bar support.Displacement transducer body displacement sensor bracket is equipped with.It is displacement sensor head below displacement transducer body.Displacement sensor bracket is also equipped with balance pivot, balance pivot supports a lever.Lever is positioned at the top of precise ball screw.Lever one transverse plane is abutted against mutually with displacement sensor head, and the lever other end is equipped with lever contact head.Balance pivot is to thinking that the distance of sensor head is equal to the distance of lever contact head with balance pivot.Above lever, spring is housed, spring one end is connected with lever, and the spring other end is connected with the fulcrum of spring be contained on displacement sensor bracket.Displacement transducer body and Miniature programmable control product PLC and are connected.Travelling workpiece is touched by the contact head on lever in moving process.When contact head moves to travelling workpiece place, contact head produces displacement upward.Contact head displacement upward makes displacement sensor head generation displacement downwards.Because balance pivot is equal to the distance of lever contact head with balance pivot to the distance of displacement transducer measuring head, this just makes the distance of contact head displacement upward equal with the distance of displacement sensor head displacement downwards.Displacement transducer converts the shift length signal recorded to analog voltage signal and is delivered to by analog voltage signal in the analog input and output module of micro programmable logic controller PLC.Such micro programmable logic controller PLC just can go out the height of travelling workpiece according to the program computation preset.This height directly reflects in the interface of top level control system WinCC.After contact head leaves workpiece, the strength of spring makes lever return to original position.
Optical transmitting set and the optical receiver of the correlation photoelectric proximity switch of mechanism for measuring diameter are contained on aluminium section bar support respectively.The light that optical transmitting set reflects should just to optical receiver.Light emitted by optical transmitting set should be arranged in vertical direction with precise ball screw.The height of light should in the scope of travelling workpiece upper-lower height.The optical transmitting set of correlation photoelectric proximity switch and optical receiver are connected with micro programmable logic controller PLC.The optical transmitting set of proximity switch and optical receiver work under the instruction of Miniature programmable control PLC, and workpiece is also doing uniform rotation simultaneously.When optical receiver can receive the light that optical transmitting set sends time, the interval timer on programmable controller PLC does not work.Pass through when light path there being workpiece and shield lights time, optical receiver just do not receive optical transmitting set send light.This signal passes on micro programmable logic controller PLC by optical receiver, and micro programmable logic controller PLC indicates its interval timer work and starts the clock.When light path not having workpiece pass through, optical receiver just can receive the light that optical transmitting set sends, this signal passes on micro programmable logic controller PLC by optical receiver, and micro programmable logic controller PLC indicates its interval timer quit work and hold the clock immediately.Micro programmable logic controller PLC can calculate the diameter of travelling workpiece according to the speed of interval timer work and workpiece at the uniform velocity movement and directly reflect in the interface of top level control system WinCC.
Described micro programmable logic controller PLC selects Siemens S7-200PLC.
Described correlation photoelectric proximity switch adopts Germany to execute a gram correlation photoelectric proximity switch.
The displacement transducer of Shanghai TM Automation Instruments Co., Ltd. selected by described displacement transducer.
Advantage of the present invention there is provided a kind of mechanical construction and control system scheme measuring the height of travelling workpiece and the measuring system of diameter, particularly this system.This measuring system has that manufacture craft is simple, low cost of manufacture, measurement is accurate, automaticity is high, regulate easily, volume is little, transport and the advantage such as easy to carry.
