Abstract
A concentric circle type plane double grinding disc device comprises a first variable frequency motor, a first transmission mechanism and a main shaft. 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 disc. The first grinding disc is externally provided with a second concentric grinding disc. The second grinding disc is driven by a second variable frequency motor. A gap is arranged between the first grinding disc and the second grinding disc. Workpieces fixed on a base plate strides the gap.
Description
Technical field
This practicality relates to the lapping device field, especially uses this device, improves " limit of the collapsing " phenomenon that causes in process of lapping.
Background technology
Traditional flat grinding device is to adopt single driven by motor belt wheel transmission to make the abrasive disk motion, and the workpiece that is fixed on the basal disc carries out relative slip with abrasive disk, comes 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 as much as possible workpiece be similar to desirable geometry, and the geometry of tool-face remains unchanged as much as possible.
General flat grinding device has adjustable frequency motor, belt wheel, main shaft, abrasive disk as shown in Figure 1 in this covering device, basal disc, the equipment such as workpiece.Its groundwork process is as follows: the variable-frequency motor in the lapping device provides power, by the band transmission, power is passed to main shaft, so that abrasive disk rotates, and be fixed under the outside loaded effect of workpiece on the basal disc, the slip relative with abrasive disk comes grinding work-piece.By formula v=r ω as can be known, because the rotating speed of the workpiece on same abrasive disk is the same, so that the excentric distance of workpiece is far away, linear velocity is larger, causes the closer to the workpiece of abrasive disk edge, amount of grinding is larger, therefore after grinding, the amount of grinding of the workpiece on around the basal disc is large, and the amount of grinding of middle workpiece is little, around namely occurring than middle low and formation intermediate projections, namely " limit of collapsing " phenomenon of workpiece.
Summary of the invention
" limit of collapsing " phenomenon that this practicality causes in process of lapping in order to improve original face lapping mill, proposed a kind of in process of lapping the uniform flat grinding device of each several part material removing rate of workpiece.
The two grinding disc devices in concentric-ring pattern plane, comprise the first variable-frequency motor, the first transmission mechanism, main shaft, described the first variable-frequency motor rotates by described the first transmission mechanism drive shaft, described main shaft connects the first abrasive disk, it is characterized in that: described the first abrasive disk is provided with the second concentric abrasive disk outward, described the second abrasive disk is driven by the second variable-frequency motor, and is gapped between described the first abrasive disk and the second abrasive disk; The workpiece that is fixed on the basal disc is crossed over described gap.
Further, the support of described the second abrasive disk is connected on the flange, and described flange connects described main shaft by bearing, and described flange is enclosed within outside the described main shaft; Described support connects the second transmission mechanism of described the second variable-frequency motor.
By formula γ=r ω as can be known, in the identical situation of rotating speed, radius is larger, and linear velocity is larger.And want so that the material removing rate of workpiece as many, then must satisfy the linear velocity of workpiece equates.So, conception of the present utility model is: basal disc is during away from the abrasive disk center, rotating speed slowly diminishes, and when the center, rotating speed slowly increases, so that the linear velocity of the workpiece on the basal disc in each position of abrasive disk approximately equals all, the material removing rate of workpiece will as many, also effectively improve " limit of collapsing " phenomenon of workpiece like this.
Thus, the utility model 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, so that the average linear velocity of outer grinding dish equates with the average linear velocity of interior abrasive disk, so the material removing rate of workpiece is basic identical.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 leave a through hole below abrasive disk, the other end connecting pipe in the hole is so that abrasive material can flow out smoothly.
The utility model has the advantages that:
1, can so that in process of lapping the material removing rate of all workpiece substantially equal, thereby can improve " limit of collapsing " phenomenon of workpiece.
2, below abrasive disk, open a through hole, abrasive material is flowed out smoothly, be conducive to process of lapping more smooth and easy, also can avoid machine to be polluted.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing, with reference to accompanying drawing 2:
The two grinding disc devices in concentric-ring pattern plane comprise that the first variable-frequency motor 1, the first transmission mechanism, main shaft 13, the first transmission mechanisms are comprised of small pulley 2 and large belt wheel 13.Described the first variable-frequency motor 1 is by 13 rotations of described the first transmission mechanism drive shaft, and described main shaft 13 connects interior abrasive disk 7.Be provided with concentric outer grinding dish 4 outside the described interior abrasive disk 7, described outer grinding dish 4 is driven by the 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 by bearing, and described flange 3 is enclosed within outside the described main shaft 13; Described support 8 connects the second transmission mechanism of described the second variable-frequency motor 11.
Described the second transmission mechanism comprises decelerator 10, carriage 9.
In process of lapping, regulate the power output of adjustable frequency motor, so that the average linear velocity of outer grinding dish equates with the average linear velocity of interior abrasive disk, so the material removing rate of workpiece is basic identical.Like this, just can improve workpiece " limit of collapsing " phenomenon in process of lapping.
As mentioned above; just can realize preferably the utility model; above-described embodiment only is exemplary embodiments of the present utility model; be not to limit practical range of the present utility model; be that all equalizations of doing according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
