Abstract
The utility model discloses a planetary gear for a grinding machine. The planetary gear for the grinding machine comprises a planetary gear body (1) and multiple holes (2) formed in the planetary gear body. The distances between centers of the holes (2) and the rim of the planetary gear body (1) are smaller than the distances between centers of the holes (2) and the center of the planetary gear body (1) so that annular buffering belts can be formed among rims of the holes (2) and the rim of the planetary gear body (1). With the structure, the annular buffering belts are formed among the rims of the holes (2) and the rim of the planetary gear body (1) and quartz wafers in the holes will not be fractured when the surfaces of the quartz wafers undergo smoothness processing by the grinding machine. Thus, the rate of finished products is improved and manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of erratic star wheel for grinder.
Background technology
Quartz wafer is to produce one of required raw material of quartz-crystal resonator, in order to guarantee the quality of quartz-crystal resonator, need to use the satisfactory quartz wafer of surface roughness, for the roughness that makes the quartz wafer surface meets the requirements, usually using grinder that flatness is carried out on the quartz wafer surface handles, the quartz wafer surface is being carried out flatness when handling, preventing several erratic star wheels and quartz wafer is placed in the perforate in the grinder card.The perforate of existing erratic star wheel is from the close together at erratic star wheel edge, and grinder fractures at the quartz wafer that the quartz wafer surface is carried out will be positioned at easily when flatness is handled the edge perforate, thereby reduced yield rate, improved production cost.
The utility model content
The purpose of this utility model is to solve the problem that grinder fractures at the quartz wafer that the quartz wafer surface is carried out will be positioned at easily when flatness is handled the perforate of erratic star wheel edge.
The technical solution adopted in the utility model is: a kind of erratic star wheel for grinder, comprise erratic star wheel body 1, several are arranged on the perforate on the erratic star wheel body, distance between the center of described perforate and the erratic star wheel body edges is less than the center of perforate and the distance between the erratic star wheel body center, makes to form the loop buffer band between the edge of perforate and the erratic star wheel body edges.
As further improvement of the utility model, the distance between the center of perforate and the erratic star wheel body edges equals 1/4 of the center of perforate and the distance between the erratic star wheel body center.
As further improvement of the utility model, it also comprises the inner ring perforate, and described inner ring perforate is uniformly distributed between perforate and the erratic star wheel body center, and described inner ring perforate is rectangular.
As further improvement of the utility model, described perforate is rectangular.
The beneficial effect that the utility model adopts is: after having adopted this structure, form the loop buffer band between the edge of perforate and the erratic star wheel body edges, grinder can not fracture the quartz wafer that is positioned at perforate when flatness is handled in that the quartz wafer surface is carried out, thereby has improved yield rate, reduced production cost.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Shown in the figure: 1 erratic star wheel body, 2 perforates, 3 inner ring perforates.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, embodiment 1 of the present utility model: a kind of erratic star wheel for grinder, comprise erratic star wheel body 1, several are arranged on the perforate 2 on the erratic star wheel body, distance between the center of described perforate 2 and erratic star wheel body 1 edge equals 1/4 of the center of perforate 2 and the distance between erratic star wheel body 1 center, make to form the loop buffer band between the edge of perforate 2 and erratic star wheel body 1 edge that described perforate 2 is rectangular.
As shown in Figure 1, preference of the present utility model: a kind of erratic star wheel for grinder, comprise erratic star wheel body 1, several are arranged on the perforate 2 on the erratic star wheel body, distance between the center of perforate 2 and erratic star wheel body 1 edge equals 1/4 of the center of perforate 2 and the distance between erratic star wheel body 1 center, make and form the loop buffer band between the edge of perforate 2 and erratic star wheel body 1 edge, described perforate 2 is rectangular, this erratic star wheel for grinder also comprises inner ring perforate 3, described inner ring perforate 3 is uniformly distributed between perforate 2 and erratic star wheel body 1 center, and described inner ring perforate 3 is rectangular.
Among the utility model embodiment 1, distance between the center of described perforate 2 and erratic star wheel body 1 edge equals 1/4 of the center of perforate 2 and the distance between erratic star wheel body 1 center, make to form the loop buffer band between the edge of perforate 2 and erratic star wheel body 1 edge, grinder can not fracture the quartz wafer that is positioned at perforate when the quartz wafer surface being carried out the flatness processing like this.
In the utility model preference, this erratic star wheel for grinder also comprises inner ring perforate 3, described inner ring perforate 3 is uniformly distributed between perforate 2 and erratic star wheel body 1 center, and described inner ring perforate 3 is rectangular, makes like this can place more quartz wafer on the erratic star wheel.
In sum, after having adopted this structure, form the loop buffer band between the edge of perforate and the erratic star wheel body edges, grinder can not fracture the quartz wafer that is positioned at perforate when flatness is handled in that the quartz wafer surface is carried out, thereby has improved yield rate, reduced production cost.
Claims (4)
