The Ultrasonic Machining of complete spheroid
Technical field
The present invention relates to a kind of a complete spheroid carried out the ultrasonic surface method for processing, belong to the spherome surface processing technique field.
Background technology
Through ultrasonic wave the metal surface is processed, have efficient height, low, the free of contamination characteristics of cost, can reduce the roughness value of metal surface.Disclose a kind of " ultrasonic metallic surface processing device " like Chinese patent CN1690231, utilized this device for metallic surface to process to reduce the metal works surface roughness value fast and effectively on various lathes, to be applied.The ultrasonic Machining cutter head is installed on the ultrasonic metallic surface processing device usually, under hyperacoustic vibration, surface of the work is carried out ultrasonic Machining, to reduce the roughness value of surface of the work.The ultrasonic wave cutter head that various versions are arranged at present is like Chinese patent document CN200946158 disclosed " ball-type cutter head ", CN201357237 disclosed " column type ultrasonic Machining cutter head " and CN201357303 disclosed " ball point type ultrasonic Machining cutter head ".The workpiece that said apparatus is processed all needs the clamping position and could process the sphere on it.
The sphere that has endoporus, plane or be connected with cylinder; Owing to there is locating surface; Easy clamping is than being easier to carry out ultrasonic Machining, like Chinese patent document CN101462229B disclosed " spherical surface integrated coarse and fine processing technique and device "; CN102218549A disclosed " a kind of revolution cambered surface processing unit (plant) "; CN2488640 disclosed a kind of " magnetic-type spheroid processing unit (plant) " and CN2223161 disclosed " major diameter spherical surface processing machine tool ", these devices are to band handle sphere or hemisphere face processing, all can not process complete sphere.
And a complete sphere will carry out ultrasonic Machining owing to do not have clamping locating surface and whole surface all will be worked into, and can not leave the clamping vestige again on the surface, so there is not a kind of Ultrasonic Machining of complete sphere so far.
Summary of the invention
The present invention is directed to the problem that existing complete spheroid ultrasonic Machining technology exists, a kind of Ultrasonic Machining of simple, convenient and reliable complete spheroid is provided.
The Ultrasonic Machining of complete spheroid of the present invention is:
Make complete spheroid to be processed around self two mutually perpendicular axis rotation, contact with the sphere of complete spheroid, accomplish the ultrasonic Machining of whole spherome surface through the ultrasonic Machining cutter head.
The present invention is when carrying out ultrasonic Machining to complete spheroid; Complete spheroid is rotated around its two mutually perpendicular axis, can both be worked into, can not leave the clamping vestige the spherome surface each point; Simple, convenient and reliable, the roughness of complete spheroid is reached below the Ra0.02.

The specific embodiment
As depicted in figs. 1 and 2; The Ultrasonic Machining principle of complete spheroid of the present invention is simpler; Complete spheroid 3 with pending ultrasonic Machining after the roughing withstands on the left apical axis 1 and right apical axis 2 that is on the same horizontal line exactly; Two apical axis and contacting on the end face of complete spheroid 3 can be all to have the arc surface (referring to Fig. 1) that the sphere radian with complete spheroid 3 matches, and can be taper seat (referring to Fig. 2).Be in contact with it and can drive the runner 4 that complete spheroid 3 rotates in one of the arranged outside of complete spheroid 3, the axis normal of the pivot center of runner 4 and left apical axis 1 and right apical axis 2 through frictional drive.In the place ahead of complete spheroid 3 ultrasonic Machining cutter head 5 is set.Make a rotation in left apical axis 1 and the right apical axis 2, or two apical axis are rotated in the same way, like this, will drive complete spheroid 3 and rotate around the axis of left apical axis 1 and right apical axis 2.Runner 4 drives complete spheroid 3 and rotates around the axis with axis normal left apical axis 1 and right apical axis 2 complete spheroid 3.Just complete spheroid 3 rotates around self two vertical axis under the drive of apical axis and runner 4.Runner 4 drives complete spheroid 3 and rotates, and the position that can make complete spheroid 3 withstand on left apical axis 1 and right apical axis 2 end faces is produced, and participates in ultrasonic Machining.Ultrasonic Machining cutter head 5 is contacted with the sphere of complete spheroid 3, and contact point can be that ultrasonic Machining cutter head 5 is arbitrarily hands-off with other parts, and ultrasonic Machining cutter head 5 can be fixed, can accomplish the ultrasonic Machining of whole spherome surface.
