2. at each bearing portion good labyrinth-type excluder or dust cover are installed.
3. workbench Y moves to adopt to coordinate and swings mandrel guide pin bushing structure and be integrated with swinging axle.
4. adopting contactless permanent magnet repulsion structure that the longitudinal pressure and the employing inclined-plane of workbench are provided--thereby the structure of roller is regulated moving, fixed magnet distance adjustment pressure.
5. another adjustment coordinate of workbench is corner φ, adopts the structure that makes permanent magnet sorption adjustment screw head, makes the φ angle both fine-tuning, can leave (conveniently assemble and disassemble grinding pin) again fast and repeat accurate return afterwards.
6. being equipped with identical and the ultrasonic transducer that power is different of installation dimension can change easily according to needs.
Further specify one embodiment of the present of invention below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention is by rotary table (2), slide core (9), swinging block (10), protection plate (3), guide bracket (6), moving magnet and cover (8), fixed magnet and roller slide block (7), inclined-plane pull bar (5) swings mandrel (15), guide pin bushing (23), sheath (4), column (17), pivoted arm (18), magnetic receiver (19), adjustment screw (20), stage clip nut (21), casing (11), ultrasonic transducer and grinding pin compositions such as (1).(for simplicity's sake, do not draw among the figure electric rotating machine and belt, swing motor and eccentric wheel--push rod system, supersonic generator does not draw yet.) it is characterized in that: the rotation of workbench, the support that moves axially and swing is rolling friction and pays, for example scheme (1): rotation worker's platform (2) is installed in the slide core (9) by rolling bearing (13), slide core is supported on the centering block (10) by V-type spherical guide (12), centering block (10) is to swing mandrel (15), ball (14), guide pin bushing (23) is hung on casing.
In order to protect each rolling friction to pay, adopt following measure: sealing: between the inwall of the urceolus of rotary table (2) and the slide core head outside cylinder (scheme (1) A place) and be installed in sheath (4) endoporus at hanger place and the outside cylinder of guide pin bushing (16) between (B place) formed labyrinth sealing.In addition, the sorption that protection plate (3) is floated with four small magnets is at the upper surface of centering block (10), cover following pendular body assembly, rotary table (2) stretches out from the hole at protection plate center, and the gap of the two can be done lessly and protection plate can be taken off cleaning easily.These dust preventions guarantee that the precision of each bearing is able to long term maintenance.
Whole centering block is by swinging mandrel (15), ball (14) and guide pin bushing (23), both can move along its axis direction again, and utilize adjustment screw (24) and spring (16) can realize that workbench (in company with centering block) is in the axial displacement adjustment of y around its axis swing.
The characteristic of utilizing the magnet same sex to repel each other, provide axial compressive force to rotary table (together with slide core): moving magnet (8) is fixed on the lower end of slide core (9) by non-magnetic aluminium cover, fixed magnet embeds the upper end of the copper shoe (7) of band roller, and this slide block can move up and down in the upright hole of guide bracket (6).On the guide bracket with the cross-drilled hole of upright hole quadrature in, insert inclined-plane pull bar (5), this bar of push-and-pull changes distance between moving, fixed magnet thereby its inclined-plane promptly promotes the lifting of roller slide block, reaches to regulate workbench and impose on workpiece and grind pressure between the pin.
