The utility model is made up of switch board, main frame and base.Main machine structure is by the main frame bearing frame, the precision lead screw charger, and high-precision workpiece position rotating device, measurement mechanism and supporting mechanism are formed.Loading procedure is that servomotor two rotates through the leading screw that cog belt drives the leading screw charger, and the leading screw charger is converted into moving horizontally of pressure head with rotational motion.The rotational angle of while encoder feedback leading screw is as the feedback quantity of displacement of pressing head.The specified rate of servomotor two and the value of feedback of encoder are done the SERVO CONTROL that relatively forms a full cut-off ring, realize the accurate control of displacement of pressing head.The clamping action of workpiece position rotating device is realized that by pneumatic element spinning movement is realized through cog belt by servomotor one, the encoder record that the workpiece deformation angle coordinate is carried by servomotor one.
Main machine frame is welded by steel plate, and profile is a U type structure, is the carrier of each device, and it has enough rigidity and intensity to bear rectification distortion and corrective force.
The precision lead screw charger provides loading force, realizes the precise displacement of workpiece is loaded through full cut-off ring displacement control.The profile of tooth belt wheel drives the leading screw rotation, and nut is done rectilinear motion along the leading screw axis.Nut is connected with the loading axle through screw two, in fairlead, slides.The fairlead gland is fixed on the housing through screw one, with the fairlead axial location.Bearing block one is fixing through round nut one, and screw three plays locking effect.Angular contact ball bearing, thrust bearing and deep groove ball bearing one are for leading screw provides support, and thrust bearing is being born the axial force of correcting process; Deep groove ball bearing one is born radial load and is provided rotation to support; Angular contact ball bearing and nut three main effects are to eliminate the bearing clearance to bearing pre-tightened, and screw four gives round nut two locking.
High-precision workpiece position rotating device has two functions: the firstth, and clamping work pieces is coaxial with rotating disk with the workpiece location simultaneously; The secondth, drive the workpiece rotation.The precision of this device directly influences the certainty of measurement of workpiece, and it is the vital device of automatic set round machine.Fixed cover is fixed on the main frame bearing frame, deep groove ball bearing one and the support of angular contact ball bearing as rotary part.The workpiece drive part is made up of profile of tooth belt wheel, flange shaft, main shaft, rotating disk; Workpiece clamp tightening bit position is made up of a minute air parcel, pinch wheels, backstay, driven gear, shaft coupling, oscillating cylinder, tracheae and driving gear.Profile of tooth belt wheel rotating band moves flange shaft, main shaft, rotating disk and workpiece clamp tightening bit position and rotates synchronously.Divide the air parcel bottom to be fixed on the main frame bearing frame, rotate with the profile of tooth belt wheel on top, and its effect is to twine tracheae when preventing to rotate.Compressed air drives the oscillating cylinder swing by dividing air parcel through tracheae; Oscillating cylinder is connected by shaft coupling with driving gear; Driving gear drives three driven gears and rotates, and driven gear is fixedlyed connected with pinch wheels with backstay, so just can realize the variation of three pinch wheels distribution diameters.When the location clamped, three pinch wheels are the inner cylinder face of workpiece pressings simultaneously, simultaneously workpiece centre is positioned at the rotating disk centre of gyration, and the rotating disk rotating band part of starting building rotates.This installs accurate positioning, and clamping range is big, compact conformation.
Measurement mechanism is the workpiece circularity detection device, can regulate the measurement point height according to the workpiece of differing heights.Base two is fixed on the main frame bearing frame, and the axis of guide and each parts of measurement mechanism top are fixed in one, can in base, slide up and down, and the locking handwheel can be locked the axis of guide, has so just realized the adjustment of measurement point height.Measure tappet and lever and be rigidly connected, lever can be swung around bearing.During measurement, lever is left in cylinder one withdrawal, under the pulling of return spring, measures tappet workpiece pressing external cylindrical surface.Workpiece is by high-precision workpiece position rotating device one week of driven rotary, the jitter values of displacement transducer real-time follow-up workpiece outer surface.When rectification and following part, cylinder one promotes deviation of lever, and return spring is stretched, and measures tappet and leaves the workpiece outer surface, and this moment, measurement mechanism was not measured.
Supporting mechanism is arranged in the opposite of pressure head, is bearing straightening force.There are triangular deformation support and ovalizing deflection to support two kinds.When workpiece was ovalizing deflection, two triangular deformation supported to rise and are higher than workpiece, and ellipse supports effect; When workpiece was triangular deformation, ovalizing deflection supported to rise and is higher than workpiece, and triangular deformation supports effect.Base three is fixed on the main frame bearing frame; The cylinder holder through bolt be fastened on base three on; Cylinder two cylinder bodies are fixed on the cylinder holder, and piston rod is connected with connecting plate through pin, drive supporting base and in dovetail groove, slide up and down; The final back-up block that drives moves up and down, and realizes the switching of two kinds of supports.Back-up block is fixed through jackscrew, realizes the back-up block quick change.
