Abstract
The invention discloses a main shaft, in particular to an adjustable eccentric shaft for a grinding wheel of a grinder. According to the adjustable eccentric shaft, a small shaft sleeve is sleeved on the shaft; and a large shaft sleeve is sleeved on the small shaft sleeve and is an eccentric shaft sleeve. The invention has the characteristics that: the adjustable eccentric shaft has a simple structure, is convenient to adjust and easy to align, and improves grinding efficiency and grinding accuracy, so that grinding sizes are more accurate; and the surface roughness of the ground workpieces is improved, and the workpieces are more attractive in appearance.
Description
Technical field
The present invention relates to a kind of main shaft, be specifically related to a kind of eccentric shaft debugged of grinder wheel.
Background technology
The centering of axle is important step of processing parts, and is special in the lathe that runs up, if good centering will cause shaft vibration bigger than normal, the grinding quality variation can't satisfy required precision.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of eccentric shaft of debugging is provided.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of eccentric shaft of debugging, be with little axle sleeve on the axle, and be with large shaft sleeve on the said little axle sleeve, said large shaft sleeve is an excentric sleeve.
Between said large shaft sleeve and the little axle sleeve swelling cover is installed.
Characteristics of the present invention are: simple in structure, debugging is convenient, is easy to centering, has improved grinding efficiency and grinding accuracy, makes the grinding size more accurate, and the surface roughness of grinding work piece improves, and workpiece is more attractive in appearance.
Description of drawings
Fig. 1 is a sketch map of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
Wherein: 1, axle 2, little axle sleeve 3, large shaft sleeve 4, swelling cover.
The specific embodiment
Like Fig. 1, shown in 2, be with little axle sleeve 2 on the axle 1, be with large shaft sleeve 3 on the said little axle sleeve 2; Said large shaft sleeve 3 is an excentric sleeve; Swelling cover 4 is installed between said large shaft sleeve 3 and the little axle sleeve 2, realize through swelling cover 4 fixing, adopt excentric sleeve make emery wheel when mounted can be accurately and the work table rotation axle center match; Axle rotates with motor together, makes grinding work piece point of contact and emery wheel point of contact be close to optimum state.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
Claims (2)
1. can debug eccentric shaft for one kind, it is characterized in that: be with little axle sleeve (2) on the axle (1), be with large shaft sleeve (3) on the said little axle sleeve (2), said large shaft sleeve (3) is an excentric sleeve.
2. the eccentric shaft of debugging as claimed in claim 1 is characterized in that: between said large shaft sleeve (3) and the little axle sleeve (2) swelling cover (4) is installed.
