The present invention is used for the instrument of the high-precision thin and long shafts part of inner hole grinding machine grinding, for a kind of tightening structure, while workpiece to be machined circumferencial direction is rotated, axially utilizing spring workpiece tightly drawn and lean against some positions, and make rotating center and rotary axis of machine tool center superposition.The present invention is installed to concentricity on lathe certain error, and when driving workpiece to rotate, the circumference that can not have influence on workpiece is beated.
The machine of flexibly connecting is the endoporus machining tool of machine industry for thin and long shafts workpiece.The use procedure of flexible connector is achieved in that the hole utilized on chassis, flexible connector is fixed on the center of the rotating shaft on inner hole grinding machine, rotary axis of machine tool there is flat centre (1) pass from flexible connector center, arm-tie (3) connects with workpiece (or being connected by clamp), arm-tie (3) is made axially to hold workpiece, the centre bore of rigid transmissions and steel ball are supported on flat centre (1), at this moment six square nuts (7) are tightened, add the active force of big spring (6), the axial location of restriction workpiece, at this moment, by the centre frame adjustment workpiece at workpiece two ends, the center superposition of the final and grinding machine power transmission shaft in Shi Qizhou center.The main shaft of lathe is rotated through flexible connector and drives workpiece to rotate, and not beating to the circumference of workpiece while that the effect of flexible connector being and driving workpiece to rotate has an impact, and workpiece steadily, is firmly rotated, realizes Precise Grinding and go out high-quality endoporus.
The difficult problem occurring solving levigate long-axle workpieces endoporus and produce ripple and cannot improve surface roughness of the present invention, can the endoporus of the thin and long shafts of grinding accurately workpiece, grinds high-quality surface.The present invention needs to coordinate centre frame instrument to use, and structure is simple, easy to use.
The present invention is the inner hole grinding instrument of machine industry for thin-walled, elongated cylinder class workpiece.Of the present inventionly there is solving wear down wall, elongated cylinder class inner hole of workpiece produces distortion, ripple and the difficult problem of surface roughness cannot be improved, can the thin thin-walled of grinding accurately, long-axle workpieces endoporus, grind high-quality surface.The present invention needs to coordinate centre frame to use, and structure is simple, easy to use.

Detailed description of the invention
As shown in Figure 1, a kind of ultra-thin long cylinder base part grinding flexible gearing, transmission shaft of machine tool center is with flat centre 1, chassis 2 and grinding machine power transmission shaft are fixed by screw, as shown in Figure 2, chassis 2 there are two nested structures identical and the fixture be parallel to each other, all with an arm-tie 3 in each fixture, with two a chain of through holes in arm-tie 3 one planes, as shown in Figure 4, for adjusting the fixed position of arm-tie 3, an equipped bolt 5 in each a chain of through hole, pocketed springs 6 on each bolt 5, each bolt 5 end is equipped with six square nuts 7, as shown in Figure 3, with pad 4 between each bolt 5 and adjustment arm-tie 3, this Structure composing flexible gearing, as shown in Figure 1, flexible gearing passes through the active force of spring 6 to straining by ring flange 8, screw 9, screw rod 10, steel ring 11, jackscrew 12, steel ball 13 fits together formation rigid transmissions, the steel ring of this device is locked by jackscrew 12, screw rod 10 screws steel ring 11 both sides and symmetry, ring flange 8 is connected with workpiece by screw 9.
Flat centre 1 supports the rigid transmissions be tightened up by steel ball 13, restrictive axial position, main shaft makes workpiece can only circular-rotation by flat centre 1, steel ball 13, flexible gearing and rigid transmissions, and axial location is constant, coordinate two center rest support workpiece, fine grinding hole size.
As shown in Figure 1, flat centre 1 and steel ball 13 limit rigid transmissions and are moved to the left, and flexible gearing tension rigid transmissions is supported on steel ball, adjusts the active force that six square nuts 7 add big spring, make the pulling force that rigid transmissions is subject to left all the time.Centre frame is coordinated to use, by the centre frame at workpiece two ends adjustment workpiece, the center superposition of the final and grinding machine power transmission shaft in Shi Qizhou center.The main shaft of lathe is rotated through flexible connector and drives workpiece to rotate, and not beating to the circumference of workpiece while that the effect of flexible connector being and driving workpiece to rotate has an impact, and workpiece steadily, is firmly rotated, realizes Precise Grinding and go out high-quality endoporus.
Operation principle of the present invention is: flat centre is arranged on place of grinding machine rotating shaft center, flexible gearing is installed, chassis 2 is screwed in transmission shaft of machine tool center, rigid transmissions and workpiece are locked by screw 9, between the end plane that steel ball 13 is arranged on flat centre 1 and the centre bore of ring flange, arm-tie through flexible connector tightens screw rod 10, adjust six square nuts 7, add the active force of big spring, rigid transmissions is made tightly to squeeze the steel ball that reclines, centre frame is utilized workpiece to be adjusted to the center of transmission shaft of machine tool, turning of work piece, detect excircle of workpiece footpath to jump.After footpath jumping is qualified, can inner hole grinding.
Main shaft drives workpiece to rotate, and workpiece circumferencial direction freely rotates, and axial location is drawn to lean against a fixing position.Because be flexibly connect, have during installation during a certain amount of error and can not affect use, therefore can accurately to work pieces process.
