Abstract

The utility model belongs to the technical field of part processing equipment, in particular to an external grinding clamp for sleeve-type parts, and solves the problem that the external surface roughness is hard to be greater than or equal to 0.8 when the sleeve-type parts are processed by a general machine tool. The external grinding clamp for the sleeve-type parts comprises a core shaft, wherein the outer side of the core shaft is sleeved with workpieces, a center hole used for positioning is formed in the center of the core shaft, a convex shoulder is arranged at one end of the core shaft, and the other end of the core shaft is fastened by a clamping nut. The external grinding clamp for the sleeve-type parts is simple in structure, low in manufacturing cost, and has a good grinding effect.

Description

Cover parts external grinding fixture
Technical field
The utility model belongs to part technical field of processing equipment, specifically a kind of cover parts external grinding fixture.
Background technology
Cover parts is a class part of often encountering in machining, and it is of wide application.Cover parts conventionally rises and supports and guide effect.The processing of cover parts generally need to be considered the technical requirement of dimensional accuracy, geometrical precision, relative-position error and surface roughness.
In the time of processing cover parts (especially thin-wall sleeve), because roughness of excircle is more than or equal to 0.8, machine tool is difficult to reach, and needs grinding.
Summary of the invention
When the utility model is processed cover parts in order to solve, machine tool is difficult to make roughness of excircle to be more than or equal to 0.8 problem, and a kind of cover parts external grinding fixture is provided especially.
The utility model is taked following technical scheme: a kind of cover parts external grinding fixture, comprise that outside cover has the mandrel of workpiece, and mandrel center is provided with the centre bore for locating, and mandrel one end is provided with convex shoulder, and the mandrel other end is fastening by binding nut.
Described hollow core shaft can be overlapped at least 2 workpiece.
The sleeve workpiece being processed into is enclosed within on mandrel, clamps with binding nut, be then placed on grinding machine, with the centre bore location on mandrel, till then the cylindrical of grinding sleeve workpiece reaches requirement.
Compared with prior art, the utility model is simple in structure, and low production cost has good ground effect.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
1-binding nut in figure, 2-workpiece, 3-mandrel.
The specific embodiment
As shown in Figure 1, a kind of cover parts external grinding fixture, comprises that outside cover has the mandrel 3 of workpiece 2, and mandrel 3 centers are provided with the centre bore for locating, and mandrel 3 one end are provided with convex shoulder, and mandrel 3 other ends are fastening by binding nut 1.
Described mandrel 3 can overlap at least 2 workpiece 2.
