Abstract
The present invention relates to a tracking type online measuring mechanism for roundness and diameter, which comprises a measuring mechanism base fixedly connected with a grinding wheel frame, wherein a tracking rocker arm which is driven by a rocker arm rotation motor to swing with a grinding wheel in a coaxial line mode is installed on the measuring mechanism base. The outer end of the tracking rocker arm is provided with three displacement sensors which contact the outer circle of a work piece to realize measurement. When an eccentric circle work piece tracks grinding processing, the present invention detects the processed work piece on line to carry out corresponding control compensation for enhancing productivity and product precision.
Description
Technical field
The present invention relates to a kind of circularity and diameter measurement mechanism, particularly a kind of tracking mode circularity and diameter on-line measurement mechanism.
Background technology
In existing technology, grinding off-centre operation (as the grinding maneton) often must be shut down circularity and the diameter that detects off-centre operation, and influence is produced and machining precision.Along with the development of modern cnc technology and grinding technique, follow the tracks of grinding technique and arrived increasingly extensive application, particularly off-centre operation is followed the tracks of in the grinding, as the grinding of bent axle etc., has more embodied its high efficiency.Owing to follow the tracks of grinding, the more difficult control of method for grinding that shape that its last grinding obtains and size results are conventional.As long as but true form and size situation can know its grinding the time just can be carried out the control corresponding compensation to a certain extent, and the precision that shapes of final control.Therefore the online detection of part to be processed has just become key.
Summary of the invention
The object of the present invention is to provide a kind of tracking mode circularity and diameter on-line measurement mechanism, when the off-centre operation workpiece is followed the tracks of grinding, can carry out online detection, thereby can carry out the control corresponding compensation, boost productivity and the product precision workpiece to be machined.
For achieving the above object, the present invention adopts following technical proposals:
A kind of tracking mode circularity and diameter on-line measurement mechanism, comprise the measuring mechanism pedestal of fixedlying connected with grinding carriage, it is characterized in that installing on the described measuring mechanism pedestal tracking rocking arm of being swung with the emery wheel coaxial cable by the driving of rocking arm rotary electric machine, the outer end of described tracking rocking arm is installed three displacement transducer contact workpiece cylindricals and is realized measuring; The mounting structure that three displacement transducers are installed in described tracking rocking arm outer end is: the fixedly connected oil cylinder in the outer end of described tracking rocking arm, a sensor stand is installed on two oil cylinder impeller-hubs of this oil cylinder, three displacement transducers distribute to be installed, when measured point of displacement transducer should be positioned at emery wheel center and workpiece and is ground in the middle of it on line of grinding points on sensor stand.
Above-mentioned measuring mechanism pedestal is covered at emery wheel by screw retention for the revolution pedestal, and fixedly connected described rocking arm rotary electric machine on the revolution pedestal, the output shaft of rocking arm rotary electric machine are fixedlyed connected with the tracking rocking arm after passing the center pit that turns round pedestal.
The present invention compared with prior art, have following conspicuous outstanding substantive distinguishing features and remarkable advantage: on the employing tracking rocking arm three displacement transducers are installed among the present invention grinding workpiece is carried out on-line measurement, obtain the morpheme data in measured workpiece cross section.Adopted on-line measurement provided by the invention mechanism, gloss is controlled the pursuit movement of grinding carriage with a control system and is followed the tracks of the corner displacement of rocking arm, tracking measurement and obtain the morpheme data in measured workpiece cross section all the time just, and can be by corresponding circularity and the diameter data of calculating.In view of the above, just can carry out the control corresponding compensation and the final precision that shapes of controlling.Compact conformation of the present invention is reasonable, and is safe and reliable, can boost productivity and the product precision.
