Abstract
The invention discloses a concentric circle type plane dual-grinding disk device which comprises a first variable frequency motor, a first transmission mechanism and a main shaft, wherein the first variable frequency motor drives the main shaft to rotate through the first transmission mechanism, the main shaft is connected with a first grinding disk, a second grinding disk is arranged outside the first grinding disk and is concentric with the first grinding disk, the second grinding disk is driven by the second variable frequency motor, a gap is reserved between the first grinding disk and the second grinding disk, and a workpiece fixed on a base disk spans the gap.
Description
Technical field
This practicality relates to the lapping device field, especially uses this device, improves " limit of the collapsing " phenomenon that in process of lapping, is caused.
Background technology
Traditional flat grinding device is to adopt the transmission of single driven by motor belt wheel to make the abrasive disk motion, and the workpiece and the abrasive disk that are fixed on the basal disc carry out relative slip, come grinding work-piece.This mechanism is comparatively common in the utilization of precise finiss, and the structure of every kind of lathe can each be different, and overall type of belt drive is the same.In process; Owing to can not carry out direct intervention to grinding motion; So correct grinding track seems even more important, grind motion and should make workpiece be similar to desirable geometry as much as possible, and the geometry of tool-face remains unchanged as much as possible.
General flat grinding device is as shown in Figure 1, and adjustable frequency motor, belt wheel, main shaft, abrasive disk are arranged in this covering device, basal disc, equipment such as workpiece.Its groundwork process is following: the variable-frequency motor in the lapping device provides power, through the band transmission, power is passed to main shaft; So that abrasive disk rotates; And be fixed under the loaded outside effect of workpiece on the basal disc, the slip relative with abrasive disk comes grinding work-piece.Can know by formula v=r ω,, make that the excentric distance of workpiece is far away more because the rotating speed of the workpiece on same abrasive disk is the same; Linear velocity is big more, causes the closer to the workpiece of abrasive disk edge, and amount of grinding is big more; Therefore after grinding, the amount of grinding of the workpiece on around the basal disc is big, and the amount of grinding of middle workpiece is little; Around promptly occurring than middle low and formation intermediate projections, just " limit of collapsing " phenomenon of workpiece.
Summary of the invention
" limit of collapsing " phenomenon that this practicality is caused in process of lapping in order to improve original face lapping mill, proposed a kind of in process of lapping the each several part material removing rate uniform in-plane lapping device of workpiece.
The two abrasive disk devices in concentric-ring pattern plane; Comprise first variable-frequency motor, first transmission mechanism, main shaft; Described first variable-frequency motor rotates through the described first transmission mechanism driving main shaft, and described main shaft connects first abrasive disk, it is characterized in that: described first abrasive disk is provided with the second concentric abrasive disk outward; Described second abrasive disk is driven by second variable-frequency motor, and is gapped between described first abrasive disk and second abrasive disk; The workpiece that is fixed on the basal disc is crossed over described gap.
Further, the support of described second abrasive disk is connected on the flange, and described flange connects described main shaft through bearing, and described flange is enclosed within outside the described main shaft; Described support connects second transmission mechanism of described second variable-frequency motor.
Can be known that by formula γ=r ω under the identical situation of rotating speed, radius is big more, linear velocity is big more.And to make the workpiece material clearance as many, the linear velocity that then must satisfy workpiece equates.So; Conception of the present invention is: basal disc is during away from the abrasive disk center, and rotating speed slowly diminishes, and during near the center; Rotating speed slowly increases; Make the linear velocity of the workpiece on the basal disc in each position of abrasive disk approximately equals all, the workpiece material clearance will as many also effectively improve " limit of collapsing " phenomenon of workpiece like this.
Thus, the present invention is designed to two abrasive disks with the single mill dish, and adopts concentric-ring pattern to place, and the gap between two dishes is generally less than 1mm.And be respectively two abrasive disks with two adjustable frequency motors power is provided, and the rotating speed that will guarantee the outer grinding dish is less than interior abrasive disk.In process of lapping, regulate the power output of adjustable frequency motor, make the average linear velocity of outer grinding dish equate, so the workpiece material clearance is basic identical with the average linear velocity of interior abrasive disk.Like this, just can improve workpiece " limit of collapsing " phenomenon in process of lapping.
Because gapped between the inside and outside abrasive disk, therefore in process of lapping, abrasive material can therefrom flow out, so will below abrasive disk, leave a through hole, the other end in the hole connects pipe, so that abrasive material can flow out smoothly.
Advantage of the present invention is:
1, can make that all workpiece material clearances are equal basically in process of lapping, thereby can improve " limit of collapsing " phenomenon of workpiece.
2, below abrasive disk, open a through hole, abrasive material is flowed out smoothly, it is more smooth and easy to help process of lapping, also can avoid machine to be polluted.

The specific embodiment
Further specify the present invention below in conjunction with accompanying drawing, with reference to accompanying drawing 2:
The two abrasive disk devices in concentric-ring pattern plane comprise that first variable-frequency motor 1, first transmission mechanism, main shaft 13, the first transmission mechanisms are made up of small pulley 2 and big belt wheel 13.Described first variable-frequency motor 1 is through 13 rotations of the described first transmission mechanism driving main shaft, and described main shaft 13 connects interior abrasive disk 7.Be provided with concentric outer grinding dish 4 in described outside the abrasive disk 7, described outer grinding dish 4 is driven by second variable-frequency motor 11, and is gapped between described interior abrasive disk 7 and the outer grinding dish 4; The workpiece 5 that is fixed on the basal disc 6 is crossed over described gap.Gap between two dishes is generally less than 1mm.
The support 8 of described outer grinding dish 4 is connected on the flange 3, and described flange 3 connects described main shaft 13 through bearing, and described flange 3 is enclosed within outside the described main shaft 13; Described support 8 connects second transmission mechanism of described second variable-frequency motor 11.
Described second transmission mechanism comprises decelerator 10, carriage 9.
In process of lapping, regulate the power output of adjustable frequency motor, make the average linear velocity of outer grinding dish equate, so the workpiece material clearance is basic identical with the average linear velocity of interior abrasive disk.Like this, just can improve workpiece " limit of collapsing " phenomenon in process of lapping.
As stated; Just can realize preferably that the present invention, the foregoing description are merely exemplary embodiments of the present invention, be not to be used for limiting practical range of the present invention; Be that all equalizations of doing according to content of the present invention change and modification, all contained by claim of the present invention scope required for protection.
