Abstract
The utility model discloses a diamond roller of a needle valve body, and relates to a grinding tool. The utility model aims at providing a grinding tool for a grinding wheel of the needle valve body, which is simple in structure, low in cost, and simple to operate. The diamond roller of the needle valve body comprises a roller body, wherein a screw hole is arranged in the roller body, the screw hole is provided with a pressing piece, the pressing piece is provided with a fastening bolt, and the surface outline of the roller body is the same as the surface outline of the needle valve body. According to the utility model, the grinding wheel for processing the needle valve body can be grinded.
Description
Technical field
The utility model relates to a kind of grinding tool, particularly relates to a kind of diamond roller of the polishing for the needle-valve body emery wheel.
Background technology
Diamond roller is a kind of grinding tool of the processing grinding wheel of polishing, diamond roller polish first emery wheel, the emery wheel metal parts of polishing again, the profile of general diamond roller and metal parts is identical, diamond roller polish the outline line corresponding with metal parts at wheel face first, then the emery wheel metal parts of polishing again, the needle-valve body of fuel injector comprises such as Fig. 1 bulb 4, omoplate 5, secondary circle 6, needle-valve body is adding man-hour, all be to go out bulb 4 with grinder buffing respectively, omoplate 5, secondary circle 6, and then they are combined, the processing of substep has guaranteed the quality of product, but also increased working strength in the time of processing, also might cause the needle-valve body sealing poor after the combination, brought serious loss and the waste of resource.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, needle-valve body diamond roller that cost is low, easy and simple to handle.
The utility model needle-valve body diamond roller comprises wheel body, and screw is arranged in the wheel body, on the described screw compressing tablet is arranged, and on the described compressing tablet fastening bolt is set, and described wheel body surface profile is identical with the needle-valve body surface profile.
Compared with prior art, the utility model wheel body surface profile is identical with the needle-valve body surface profile, the emery wheel corresponding with the needle-valve body surface profile of can polishing, emery wheel can polish the needle-valve body of one, need not polish step by step, recombinant has reduced operation, save resource, increased the sealing of needle-valve body.
Below in conjunction with accompanying drawing the utility model needle-valve body diamond roller is described further.
Description of drawings
Fig. 1 is the needle-valve body front view;
Fig. 2 is the utility model needle-valve body diamond roller cut away view.
The specific embodiment
As shown in Figure 2, the utility model comprises wheel body 1, in the wheel body 1 screw is arranged, and compressing tablet 2 is arranged on the screw, and fastening bolt 3 is set on the compressing tablet 2, and wheel body 1 surface profile is identical with the needle-valve body surface profile.
The utility model is fixed on wheel body 1 on the lathe with fastening bolt 3 and compressing tablet 2 first in use, wheel body 1 surface profile is identical with the needle-valve body surface profile, so the surface profile of the emery wheel that body 1 polish can be corresponding with the needle-valve body surface profile, with this emery wheel needle-valve body of directly polishing, both can obtain integrated needle-valve body again, polishing need not distribute, recombinant, reduce operation, saved resource, also increased the sealing of needle-valve body.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
