Abstract
The utility model provides a fixture for grinding the inner bore of a thin-wall component, which solves the technical problem of grinding hole deformation. The fixture for grinding the inner bore of a thin-wall component comprises a fixture body, an auxiliary component platen, bolts and a positioning bar, wherein the fixture body is installed on an inner bore grinding machine; the positioning bar is a single piece; the diameter of the positioning bar is the same as the size of a bore diameter before a workpiece is machined; and the positioning bar is installed on the fixture body when the positioning bar is used and is taken out when the positioning bar is not used. The positioning bar is used for centring the workpiece, the workpiece is fastened by the platen and the bolts and does not deform when the inner bore is machined, and thus the machining technical requirements can be satisfied.
Description
Technical field
The utility model relates to the machining anchor clamps, is specifically related to a kind of thin-wall part mill internal clamp.
Background technology
Produce gear, conventional mill internal clamp is to adopt folder gear ring or folder peripheral milling endoporus, and thicker for wall ratio, interior hole dimension is little, and this anchor clamps can satisfy its technological requirement; But for thin-wall workpiece, interior hole dimension is bigger, and workpiece very easily is out of shape in the processing, can not satisfy technological requirement if grind endoporus with above-mentioned anchor clamps again.
Summary of the invention
The utility model provides a kind of thin-wall part mill internal clamp, solves above-mentioned problem on deformation.The utility model thin-wall part mill internal clamp is made of clamp body and auxiliary pressing plate, bolt and locating bar; Wherein clamp body is installed on the endoporus grinding machine; Locating bar is a single-piece, and locating bar diameter and workpiece processing front aperture are measure-alike, and the time spent is contained on the clamp body, and the time spent does not take out.
The utility model is helpful to be: avoided workpiece deformation, satisfied the processing technology requirement.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is thin-wall part mill internal clamp figure.
Among the figure: clamp body 1, workpiece 2, datum level 3, locating bar 4, pressing plate 5, bolt 6.
The specific embodiment
As shown in Figure 1, thin-wall part mill internal clamp is made of clamp body 1 and auxiliary pressing plate 5, bolt 6 and locating bar 4; Wherein clamp body 1 is installed on the endoporus grinding machine; Locating bar 4 is single-pieces, and locating bar 4 diameters and workpiece 2 processing front apertures are measure-alike, and the time spent is contained on the clamp body 1, and the time spent does not take out.
In the operation, at first clamp body 1 is installed on the endoporus grinding machine; The face that workpiece 2 end faces and clamp body 1 fitted is as datum level 3, to datum level 3 centerings in 0.01mm; Workpiece 2 just is contained on the locating bar 4, and then locating bar 4 is contained on the clamp body 1, utilizes locating bar 4 with workpiece 2 centering; Workpiece 2 end faces and clamp body 1 post, and install pressing plate 5, tight a bolt 6, fix workpiece 2 after, locating bar 4 is taken out.Start lathe mill endoporus, because workpiece 2 is fastened, process can not deform, and grinding out can satisfy technological requirement.
