Description
Technical field
The utility model belongs to thin-walled ring parts technical field of processing equipment, and in particular to one kind is used to process thin-walled ring
The fixture of external diameter.
Background technology
Thin-walled shaped part because have the characteristics that it is in light weight, save material, compact-sized, be widely used at present respectively
Each industry of row.But the processing of thin-walled shaped part is to compare stubborn problem in turning, grinding, and reason is thin-walled shaped part rigidity
Difference, intensity are weak, are on the one hand easily acted on deformation by the chucking power of clamping device, and another aspect work in-process is (special by cutting force
It is radial cutting force) effect, vibration deformation is easily produced, thus increase the Form and position error of thin-walled shaped part, dimensional accuracy is low,
Change in shape is big, positional precision and surface roughness are poor, and yield rate substantially reduces.
In order to improve yield rate, difficulty of processing is reduced, patent application CN201020615596.3 discloses a kind of be used for greatly
The clamp structure of type thin-walled shape part processing, by the way that thin-walled ring is through on the round boss in clamp body center, then use clamp body
The pressing plate of surrounding compresses thin-walled ring and then is processed, but the clamping plate of the clamp structure is distributed on the circumference of clamp body, extremely
Two pressing plates are needed to realize the function of clamping thin-walled ring less, it is cumbersome, and also thin-walled loop section end face is not in contact with pressing plate,
Partly by platen clamp, cause overall unbalance stress, add because the degree of chucking power effect deformation, machining accuracy greatly drop
It is low, and the clamp platen blocks the periphery of thin-walled ring, therefore it is not appropriate for the external diameter for processing thin-walled ring.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is that providing one kind is used to process thin-walled ring external diameter
Fixture.The fixture can be with clamping single-piece or clamping more than one piece thin-walled shaped part simultaneously, and face face is bonded between thin-walled ring and fixture, by
Power is uniform, firm grip and is unlikely to deform, and for processing thin-walled ring external diameter, is advantageous to improve thin-walled ring machining yield.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions：
A kind of fixture for being used to process thin-walled ring external diameter, including jig main body, pressing plate and nut, described jig main body one end
For body base, the other end is main body mandrel, and mandrel end has a screw thread, and the center of the pressing plate has a circular hole, thin-walled ring and
Pressing plate is through on jig main body mandrel successively, and by nut, in mandrel end, fastening clamps to thin-walled ring.
According to a specific embodiment of the present utility model, the above-mentioned fixture for being used to process thin-walled ring external diameter, the pressing plate
For a plane bearing.
When thin-walled circular rector is big and diameter is little, using plane bearing type fixture, while multiple thin-walled rings are clamped, fixture pressure
Its tight end face is processed, and is advantageous to improve processing efficiency.
According to another specific embodiment of the present utility model, the above-mentioned fixture for being used to process thin-walled ring external diameter, the master
Body mandrel includes two different steps of radius, and the first step being connected with body base is used to penetrate thin-walled ring, positioned at end
Second step be used for penetrate pressing plate.
Further, the above-mentioned fixture for being used to process thin-walled ring external diameter, the radius of the first step are more than second step.
Further, the above-mentioned fixture for being used to process thin-walled ring external diameter, the length of the first step are less than thin-walled ring
Thickness.
The fixture of two mandrel steps with different radii, the larger thin-walled ring of bore dia is primarily adapted for use in, because working as
When thin-walled annular distance is relatively large in diameter, if mandrel is same Radius, meet demand will be unable to the nut of stock size, if using
Nut is customized, then the defects of bringing frock overweight again, therefore, fixture of the design with two-stage step is more advantageous.For this
Kind fixture, the length of the first step are less than the thickness of thin-walled ring, just can guarantee that pressing plate can be pressed on thin-walled ring end face.
The utility model is above-mentioned to be used to process the fixture of thin-walled ring external diameter, between the body base and thin-walled ring of fixture, thin
Contact between wall ring and pressing plate is that face contacts with the fitting in face, therefore, each several part stress equalization, when essentially eliminating fastening
Thin-walled annular strain caused by clamping force, while also reduce caused vibration in the presence of cutting force (particularly radial cutting force)
Transmission, ensure dimensional accuracy, shape, positional precision and the surface roughness of workpiece.And the external diameter of thin-walled ring fully exposes,
Be advantageous to the processing of thin-walled ring external diameter.
