Description
Technical field
The present invention relates to a kind of grinding equipment, particularly relate to a kind of vertical ultrasonic cylindrical grinding equipment.
Background technology
In the automatic control system of modern industry, more and more higher for the reliability requirement of electrohydraulic servo valve, hydraulic valve, vane regulator etc., and spool and valve pocket surface topography also had higher requirement.Mainly finish by processing technologys such as grindings for this class part at present, and simple grinding can not have been satisfied the demand of industrial development, in grinding, add the machined surface quality that ultrasonic vibration can significantly improve work piece.The ultrasonic vibration honing is the application of UVC in honing, has that honing power is little, the honing temperature is low, machined surface quality and a machining accuracy advantages of higher, can solve the problems such as oilstone easily stops up in the common honing process, honing efficient is low.
According to the precision machined actual demand of cylindrical, ultrasonic vibration is applied in the cylindrical honing processing, can not only carry out finished machined to surface of the work, and can also form overlapping curve at surface of the work, this has good oil storage effect during for the spool quick sliding, keep good greasy property, to improve reliability and wearability.
The ultrasonic honing equipment of present document and practical application, its structure roughly has two kinds of situations, be 201020672721.4 such as number of patent application, 200620031811.9,99108124.2 and 201210047050.6 the ultrasonic honing equipments such as patent, to be dither that transducer is produced be delivered to oil stone base by ultrasonic transformer after with energy accumulating to its course of work again, make the oilstone abrasive particle produce ultrasonic vibration and be used for processing, this structure is in the prior art of ultrasonic honing equipment, the complex structure of grinding equipment, replacing oilstone difficulty, ultrasonic energy transmission chain length, energy loss is larger in the transmittance process, and particularly amplitude fading is large, is unfavorable for workpiece processing.
Another kind is to be 201110202887.9 patent such as number of patent application, behind the oil stone base fluting, to embed transducer, make oilstone produce extensional vibration and then drive the oilstone abrasive particle and vibrate, this structure is higher for the oil stone base processing request, how accurate no matter the transducer piezoelectric chip that particularly embeds in the oil stone base made, all can difference on the vibration frequency that produces and amplitude, that is to say that the oilstone on the same honing head can produce different vibrations, this is fatal defective for Precision Machining.
Number of patent application is 201120090850.7 patent in addition, it is a kind of cylindrical honing head by hydraulic control centering feeding, can carry out fine finishining to the outer round surface of work piece, this structure honing head work in-process is rotation and does axially reciprocating, and controlled by hydraulic pressure with the radial feed of honing head motion oilstone, structure is comparatively complicated, and the accuracy of manufacture of correlated parts requires very high, and changes the oilstone difficulty.
For the research of cylindrical grinding equipment with introduce also fewerly, being 94228509.3 patent such as the patent No. at present, is to process for the slender axles outer surface; This structure is suitable for the cylindrical honing of large-scale workpiece, can not realize that the processing of Small Cylindrical body and machining accuracy are lower.
