Background technology
High strength, high rigidity compact-type emery wheel adopt traditional method for trimming to be difficult to wheel face quality and the dressing efficiency that reaches desirable.Adopt common method for trimming, dressing tool and abrasion of grinding wheel are fast, and dressing efficiency is low, and the wheel face quality can't guarantee, finishing cost height.Compact-type diamond grinding wheel dressing technology at various hard brittle material processing object exploitations, though solved the finishing problem of emery wheel to a certain extent, but still existed dressing accuracy and limitation such as dressing efficiency is low or trimming device is expensive, working service inconvenience.
Ultrasonic machining is by the certain acoustic system signal of telecommunication to be converted into mechanical oscillation, make that cutter (or workpiece) produces the following a kind of material removal process method of clocklike controlled vibration, on average cutting force is little, cutting temperature is low, and surface damage and residual stress are all less.The tradition elliptical vibration is driven by two ultrasonic exciting vibration sources, and circuit complexity, vibrational system complex structure, volume are greatly, adjustment is difficult and be unfavorable for production application.
Summary of the invention
The object of the invention is to provide a kind of simple and reliable single excitation elliptical ultrasonic vibration trimming device, is used to realize the elliptical ultrasonic vibration finishing of compact-type hard grinding wheel.
To achieve these goals, the present invention adopts following technical scheme: a kind of single excitation elliptical ultrasonic vibration trimming device, comprise pedestal, the pedestal upper end laterally is provided with compound elliptical vibration luffing bar, be provided with clamp mechanism and centre-height guiding mechanism between pedestal and the compound elliptical vibration luffing bar, front end one side of compound elliptical vibration luffing bar is provided with diamond pen, and the rear end of compound elliptical vibration luffing bar is provided with transducer, and transducer is connected with supersonic generator by cable.
Described clamp mechanism and centre-height guiding mechanism comprise vertical long through-hole that is arranged on pedestal top and the bolt that passes long through-hole and fix with compound elliptical vibration luffing bar.
Described compound elliptical vibration luffing bar is made of for three sections cylindrical end, rectangle coupling part, vibration conversion end.
Described pedestal is provided with and is used for and the fixing fixed bolt hole of guideway of grinding machine.
Described diamond pen is pressed on the end of compound elliptical vibration luffing bar by welding or screw thread, compound elliptical vibration luffing bar be connected by studs with transducer.
Being provided with the vertical direction angle at the end upside near the vibration conversion end of rectangle coupling part is the slope of α, wherein 0 °＜α＜90 °.
The present invention has broken through traditional elliptical ultrasonic vibration method for trimming, not using under two excitation ultrasonic power situations, realizes the elliptical ultrasonic vibration finishing of emery wheel.Use the single supply excitation to carry out oval ultrasonic vibration dressing processing, sound system is simple in structure on the one hand, and input cost is lower; On the other hand, the TRAJECTORY CONTROL of diamond pen is simple in the process, is easy to improve working (machining) efficiency, improves the wheel face quality.The compound elliptical vibration luffing bar that this device uses can be converted to extensional vibration and oscillation crosswise with the longitudinal ultrasonic vibration of the single direction of transducer, synthesize elliptical vibration at compound elliptical vibration luffing bar end, drive diamond pen and carry out the ellipse finishing.By controlling a structural parameters α of compound elliptical vibration luffing bar, control the parameter of horizontal ultrasonic vibration, thereby the terminal synthetic elliptical orbit shape of control reaches the purpose of controlling the diamond pen movement locus.The compound finishing structure that this device has proposed single vibration source driving elliptical ultrasonic vibration has realized the simple control of diamond pen elliptical orbit, can be used for the precise high-efficiency finishing of high strength, high rigidity compact-type hard grinding wheel.
