Abstract

The utility model provides a polishing disk, includes polishing disk, descends polishing disk and a plurality of work piece cushion, on polishing disk is located down to the work piece cushion, in the same transverse section, down polishing disk's the centre of a circle and the nearly centre of a circle of work piece cushion grow between the mid point of limit that angle range is 40 - 50 between line and the same long limit. The utility model discloses compact structure, processing is simple, work efficiency is high, and single processing work piece volume is markedly increased in the same transverse section, and relative and prior art polishes the equivalent amount work piece, as long as polishing disk excircle direction arranges that polishing effect obviously strengthens under leaning on the work piece as far as possible, the high -usage of lower wall has reduced the waste in space, total area of contact increase of polishing disk and work piece cushion, total area of contact increase of going up polishing disk and work piece promptly, it is lighter to go up the wearing and tearing that polishing disk appears, to polishing disk's equating number of times reduction, has prolonged polishing disk's life greatly, the polishing disk wearing and tearing are more even, and the frequency and the work load of repairing the dish reduce, have reduced the processing cost.

Description

A kind of polishing disk

Technical field

The utility model relates to machining apparatus, refers in particular to a kind of polishing disk.

Background technology

Existing polishing machine workpiece cushion block arrangement (see Fig. 1), workpiece cushion block fastens with glue on lower polishing disk, workpiece cushion block and inner circle tangent, the product that need process is positioned on workpiece cushion block, as can be seen from Figure 1, its cloth sheet mode space waste is large, and workpiece pad number of blocks is few, the product quantity simultaneously processed is few, and single process efficiency is low; Meanwhile, because of the waste in polishing disk space, in the polishing process of polishing disk and product, make polishing disk greatly not participate in polishing, under equal rotating speed, polishing disk utilization rate is low; And after polishing disk wearing and tearing, dish need be repaiied to polishing disk, the polishing disk part equating of work will be had neither part nor lot in, thus cause the waste of polishing disk.

Polishing disk is little near home position linear speed, thus the position polishing ability the closer to the center of circle is poorer, for ensureing polishing effect, workpiece cushion block is generally arranged near lower polishing disk cylindrical as far as possible, arrange workpiece cushion block less near lower polishing disk home position as far as possible or do not arrange workpiece cushion block, finally cause single process workpiece amount low, polishing disk space is by serious waste, and working (machining) efficiency is low;

Because total contact area of workpiece cushion block and polishing disk is little, the position that upper polishing disk has neither part nor lot in polishing can form projection, for ensureing that polishing precision and efficiency need to carry out equating to this part projection of upper polishing disk, causes polishing disk consumption serious.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, provides that a kind of operating efficiency is high, the polishing disk of longer service life.

The utility model solves the technical approach that its technical problem adopts, a kind of polishing disk, comprise polishing disk, lower polishing disk and plurality of workpieces cushion block, described workpiece cushion block is located on lower polishing disk, in same lateral cross section, between the center of circle of described lower polishing disk and long limit, the nearly center of circle mid point of workpiece cushion block, between line and same long limit, angular range is 40 °-50 ° (preferably 45 °).

Further, the arrangement mode of described workpiece cushion block be following polishing disk the center of circle centered by put annular array.

Further, described workpiece cushion block is rectangle.

Compared with prior art, the utility model compact conformation, processing is simple; Operating efficiency is high, in same lateral cross section, between the center of circle of described lower polishing disk and long limit, the nearly center of circle mid point of workpiece cushion block, between line and same long limit, angle is acute angle, single process workpiece amount obviously increases, and relative and prior art, carries out polishing to equivalent amount workpiece, as long as tried one's best by workpiece, the outer circular direction of polishing disk is on the lower arranged, polishing effect obviously strengthens, and the utilization rate of lower wall is high, decreases the waste in space; Total contact area of polishing disk and workpiece cushion block increases, and the total contact area namely going up polishing disk and workpiece increases, and the wearing and tearing that upper polishing disk occurs are comparatively light, reduce, substantially prolongs the service life of polishing disk to the equating number of times of polishing disk; Polishing disk wearing and tearing evenly, repair the frequency of dish and workload reduces, reduce processing cost.

Accompanying drawing explanation

Fig. 1 is the structural representation of polishing disk under prior art;

Fig. 2 is the polishing disk structural representation of the utility model one embodiment.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described further.

Embodiment

With reference to Fig. 2, the present embodiment comprises lower polishing disk 1 and plurality of workpieces cushion block 2, and described workpiece cushion block 2 is located on lower polishing disk 1, and centered by the center of circle of workpiece cushion block less than 2 polishing disk 1, lattice array is arranged; In same lateral cross section, between the center of circle of lower polishing disk 1 and long limit, the nearly center of circle mid point of workpiece cushion block 2, between line and same long limit, angle is 45 °.

Described workpiece cushion block 2 is rectangle.

In same lateral cross section, between the center of circle of lower polishing disk 1 and long limit, the nearly center of circle mid point of workpiece cushion block 2, between line and same long limit, angle is 45 °, the usable floor area of lower wall can be utilized fully, transfer the product of greater number at same homalographic.In working order, polishing disk is relative with the contact area of product in radial directions to be increased, and the area of polishing disk participation work increases, and weares and teares more even.

Use the utility model compact conformation, processing is simple; Operating efficiency is high, in same lateral cross section, between the center of circle of described lower polishing disk 1 and long limit, the nearly center of circle mid point of workpiece cushion block 2, between line and same long limit, angle is acute angle, single process workpiece amount obviously increases, and relative and prior art, carries out polishing to equivalent amount workpiece, as long as by workpiece as far as possible on the lower the outer circular direction of polishing disk 1 arrange, polishing effect obviously strengthens, and the utilization rate of lower wall is high, decreases the waste in space; Total contact area of polishing disk and workpiece cushion block 2 increases, and the total contact area namely going up polishing disk and workpiece increases, and the wearing and tearing that upper polishing disk occurs are comparatively light, reduce, substantially prolongs the service life of polishing disk to the equating number of times of polishing disk; Polishing disk wearing and tearing evenly, repair the frequency of dish and workload reduces, reduce processing cost.

Claims

1. a polishing disk, it is characterized in that, comprise polishing disk, lower polishing disk and plurality of workpieces cushion block, described workpiece cushion block is located on lower polishing disk, in same lateral cross section, between the center of circle of described lower polishing disk and long limit, the nearly center of circle mid point of workpiece cushion block, between line and same long limit, angular range is 40 °-50 °.
