Abstract

The utility model relates to a precision grinding machine with a correcting ring, comprising a machine seat, a speed regulation mechanism, a grinding disk, a work piece clamping ring, a correcting ring, etc. The output shaft of a motor is also connected with a double-connecting belt pulley by a gear mechanism. One path drives a driving friction pulley on a correcting claw, the work piece clamping ring for holding a work piece, and a driven friction pulley to rotate, and the other path drives the driving friction pulley on the correcting claw, the correcting ring, and the driven friction pulley to rotate. The precision grinding machine with a correcting ring real-timely correct the surface of the grinding disk in the process of work piece processing, and the rotary angle of the correcting claw is changed. The eccentricity quantity of the work piece away from the center of the grinding disk can be regulated to obtain high plane precision. Pressure is needed, which can be realized so long as a load is added to the work piece.

Description

Precision finishing machine with correcting ring

The utility model relates to the plant equipment that is applicable to the grinding work piece plane, a kind of precision lapping machine.

Traditional grinder is in the process of processing work, be can't the align hone dish plane precision, along with constantly carrying out of process, the plane precision of abrasive disk can be worse and worse, thereby be difficult to guarantee that workpiece obtains high plane precision in process, also be difficult in and obtain high surface quality in the short time.

The utility model adopts one to keep workpiece to be machined to do stable motion, and has a holding ring of align hone dish, another and holding ring same size, identical shaped conditioning ring, two encircle all the precision lapping machine of align hone dish constantly in process, to obtain high as far as possible plane precision.

The technical solution of the utility model is: it comprises support, speed adjusting gear, abrasive disk, piece-holder ring.Pinion on the motor output shaft in speed adjusting gear is behind gear wheel, duplex belt pulley, one the tunnel through belt, big belt pulley, little driving wheel, belt, drive and revise active friction wheel rotation on the pawl, revise on the pawl symmetric position driven pulley is housed, block on the circumference of bottom surface and have chip area, in workpiece is housed holding ring rotate; Another road drives another and revises active friction wheel rotation on the pawl through another belt, big belt pulley, little driving wheel, belt, and another is revised on pawl symmetric position driven pulley is housed, and blocks the conditioning ring that has chip area on the circumference of bottom surface and rotates.

Owing to adopted a holding ring stably to rotate with the workpiece in the retaining ring, and on the relative position of holding ring, adopted one with the holding ring same size, identical shaped conditioning ring, like this on abrasive disk on the one hand holding ring keep workpiece stably to rotate, on the other hand holding ring and conditioning ring all can be in process align hone panel surface constantly.Because abrasive disk weares and teares, and influences the plane precision of workpiece to be machined, can adjust offset by changing two corners of revising pawl, to adjust the processing capacity of surface of the work each point, to obtain high as far as possible plane precision in process.

The utility model is compared the useful effect that is had with background technology:

1. keep workpiece with holding ring, come real-time align hone panel surface with conditioning ring;

2. with machine governor motor output shaft is carried out doing stepless speed regulation in 0～200rpm scope;

3. pressurization is only done and need loading can be realized on workpiece.

Optical element, crystal element, metal parts or metallographic specimen that this grinder can be used on the plane grind or polishing.

The utility model will be further described below in conjunction with accompanying drawing.

The structure principle chart of the precision lapping machine of Fig. 1, band conditioning ring;

The vertical view of the precision lapping machine of Fig. 2, band conditioning ring.

As shown in Figure 1 and Figure 2, the utility model comprises support 4, DC motor speed-regulating device 1, direct current generator 3, abrasive disk 19, piece-holder ring 22 etc.The 220V alternating current is as power supply, carry out stepless speed regulation by 1 pair of direct current generator of DC motor speed-regulating device 3, direct current generator 3 decelerates to 1/3 of motor speed by the small belt pulley on the I 6, V belt 11, the big belt pulley 12 that is contained on the IV with the abrasive disk on the axle IV; Another road is

pinion

5 and 7 engagements of the gear wheel on the II on 3 I of direct current generator, with the change rotation direction, and slows down 1/3.The big belt pulley 10 of duplex belt pulley 2 difference one tunnel on V belt 8, axle III on the axle II drives little driving wheel 16, by belt 20, drive and revise the initiatively rotation of pawl 24 active friction wheels, 17 dos, revise on pawl 24 symmetric positions driven pulley 23 is housed, block having holding ring 22 rotations that workpiece 18 is housed in the chip area on the circumference of bottom surface, drive driven pulley 23 and rotate; The big belt pulley 13 of another road on V belt 9, axle V drives little driving wheel 25, by belt 20 ', drive and revise pawl 24 ' upward initiatively rotation of active friction wheel 17 ' do, revise be equipped with on pawl 24 ' symmetric position driven pulley 23 ', block the conditioning ring 21 that has chip area on the circumference of bottom surface and rotate, drive driven pulley 23 ' rotation.Conditioning ring and holding ring employing corrosion-resistant material such as brass, stainless steel, pottery etc. are made.The surperficial each point linear velocity owing to abrasive disk 19 is different on the one hand with holding ring 22 for conditioning ring 21, and driven pulley is adopted in rotatablely moving of work and hard seat dish 19 switched in opposite, makes rotation more stable.Workpiece 18 is placed on processing in the holding ring 22, and pressurization is as long as loading can realize on workpiece.After abrasive material adds from abrasive disk 19, can 14 outflows along the lapping liquid exit.Regulate two trip bolts of revising on the pawl 24 15, change the corner of revising pawl 24, promptly regulate workpiece from the offset at abrasive disk center and conditioning ring offset, to obtain high as far as possible plane precision from the abrasive disk center.
