Description
The utility model relates to honing machine, relates in particular to numerical control constant force feeding ultrasonic honing machine.
Common honing is to utilize some oilstones being installed on the honing head circumference, with oilstone distending radially, makes it press to the workpiece hole wall, the contact of formation face by oilstone distending mechanism.During honing head work, rotate and linear reciprocating motion, to finish low speed grinding to hole wall.During common honing, because rotatablely moving and linear reciprocating motion of honing head makes the reticulate pattern that the lip-deep Cutting trajectory of abrasive particle in the hole becomes to intersect and don't repeat on the oilstone.There is two large problems in common honing:
1) common honing efficient is lower, and especially working (machining) efficiency is extremely low when honing thin-walled parts, toughness material and hard brittle material.During toughness materials such as honing copper, aluminium, titanium alloy, oilstone very easily stops up, and surface quality is very poor, and working (machining) efficiency is extremely low.
2) oilstone distending pressure changes greatly during level perssure feed, and when deciding the journey feeding, oilstone distending pressure is controlled with operator's experience and feel, causes the oilstone anomalous fracture, workpiece deformation and even scrap.
The purpose of this utility model provides a kind of efficient height, oilstone distending constant pressure, the oilstone numerical control constant force feeding ultrasonic honing machine that cracky, impedance matching are not easily, frequency is easy to follow the tracks of, crudy is high.
In order to achieve the above object, the utility model is taked following measures:
Numerical control constant force feeding ultrasonic honing machine has ultrasonic honing equipment, the ultrasonic honing equipment upper end is provided with swinging gas joint, divide into oilstone, be provided with nozzle between oilstone and the oilstone, pressure signal from nozzle is issued computer through the pneumatic-to-current converter conversion by the in-process measuring instrument table, and optoelectronic switch is issued computer with detection signal simultaneously, control step motor and oil cylinder are by the oilstone distending of pinion, gear wheel, shaft coupling, torque rotary speed sensor drive ultrasonic honing equipment.
Advantage of the present utility model:
Series of advantages such as 1) ultrasonic honing has that honing power is little, the honing temperature is low, oilstone is difficult for obstruction, production efficiency height, crudy are good, can solve the honing problem of hard brittle material parts such as toughness material, thin-wall cylinder casing and pottery, hardened steel such as problem, especially copper that common honing exists, aluminium, titanium alloy.
2) adopt numerical control constant force feeding system can prevent the anomalous fracture problem that oilstone produces because of pressure is excessive effectively, reduce the part processing distortion, improve machining accuracy.
3) oilstone distending constant pressure can solve the resistance matching problem between ultrasonic transducer and the generator effectively, and ultrasonic honing sound system resonant frequency is implemented effectively from motion tracking.
4) it is convenient that the transaudient efficient height of ultrasonic honing sound system, oilstone are changed and repaired.
Sandwich type piezoelectric transducer and luffing bar that cylindrical hole is arranged in the middle of 5) ultrasonic honing equipment adopts can make the radially automatic distending of oilstone under the non-stop-machine condition of lathe.
Numerical control constant force feeding ultrasonic honing machine can be widely used for automobile, the powerful honing of cylindrical holes such as tractor, motorcycle, tank, panzer, boats and ships, aircraft, radio and television equipment, oil cylinder, damper, injection machine, gun tube, recoil cylinder, coal mine hydraulic supporting, the thick top gem of a girdle-pendant, the thick top gem of a girdle-pendant and the processing of the light top gem of a girdle-pendant.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a numerical control constant force feeding ultrasonic honing machine structural representation;
Fig. 2 is the ultrasonic honing equipment structural representation;
Fig. 3 is that ultrasonic honing equipment structure A is to view.
Numerical control constant force feeding ultrasonic honing machine is dynamo-electric sound integrated technique and the integrated high-new full-automatic honing machine of informationization technology.It is by supersonic generator, ultrasonic honing equipment, and closed loop on-line measurement system, numerical control and analogue system, honing head storehouse, robot, anchor clamps and plover mill machine lathe bed are formed.
Apply the vibration of longitudinal ultrasonic ripple, vibration frequency f 〉=18kHz to oilstone.To be supersonic generator change into superaudible electric oscillation signal with the AC power of 220V/380V to the operation principle of ultrasonic honing sound system, ultrasonic transducer is converted into the vertical mechanical oscillation of supersonic frequency with the electric oscillation signal of supersonic generator output, the luffing bar is passed to flexural vibration disk after the extensional vibration of transducer is amplified, flexibility bar is passed to oil stone base after converting the flexural vibrations of flexural vibration disk to extensional vibration, and oil stone base drives the oilstone that is linked together with it and carries out extensional vibration.
During the every reciprocating motion of honing head one time, radially distending is once for oilstone.Oilstone is distending 0.3～5 μ m radially, determines oilstone distending speed by measuring oilstone distending pressure or honing power, determines by the active measurement mechanism whether the honing process stops.Lathe is provided with two databases, one be that honing head moves back and forth once, oilstone distending amount database radially, another is acoustic impedance and automatic frequency tracking system database.
Be provided with nozzle 10 between the oilstone 11 of the utility model honing head and the oilstone, honing head is used as gauge head, because of gauge head ceaselessly rotation in honing processing, thus need single-revolution formula gas joint 13, as shown in Figure 1.Be transformed into the signal of telecommunication from the pressure signal of gaging nozzle 10 by pneumatic-to-current converter, enter the in-process measuring instrument table then.When honing during to the needs size, the in-process measuring instrument table sends signal and gives computer, 4 counter-rotatings of control step motor, and the oilstone deployment system shrinks, and the control honing head withdraws from workpiece (representing with arrow among Fig. 1).
Optoelectronic switch 9 is used to detect the reciprocating motion number of times of honing head.Optoelectronic switch 9 is delivered to computer with signal, and control step motor 4 is just changeing, and by pinion 5, gear wheel 6, shaft coupling 7, torque rotary speed sensor 8, drives the oilstone deployment system, makes radially distending of oilstone 11.Oilstone radially distending amount and honing head moves back and forth number of times and adapts.
Torque rotary speed sensor 8 is used to detect the honing masterpiece and is used in moment on the oilstone deployment system, and signal is delivered to computer.When moment greater than when setting value, even honing head is moving back and forth, computer can not send signal controling stepping motor 4 yet, makes radially distending of oilstone.When moment less than when setting value, when honing head moved reciprocatingly, computer can send signal controling stepping motor 4 and make radially distending of oilstone.
