Description
Technical field
The utility model relates to fixture, particularly relates to a kind of thin-walled external member Excircle machining fixture.
Background technology
Cover parts is used to supporting rotating shaft and parts on shaft or is used for leading, and the major surfaces of such part is endoporus and cylindrical, and its main technical requirements is size and the circularity requirement of endoporus and cylindrical; Axiality requirement between inside and outside circle; The perpendicularity requirement of axially bored line and end face.Thin-wall sleeve parts wall thickness is very thin, and radial rigidity is very poor.Prior art by the impact of the factors such as cutting force, heat in metal cutting and clamping force, is very easily out of shape in process, and deformation extent is serious, causes above every technical requirement to be difficult to ensure.
Utility model content
For the problems referred to above, the utility model provides a kind of thin-walled external member Excircle machining fixture.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the utility model discloses a kind of thin-walled external member Excircle machining fixture, end face tapered sleeve, resilient sleeve, inner conical drogue and locking nut that its structure comprises axle and is sheathed on from left to right successively in axle, described resilient sleeve and end face tapered sleeve are fixedly connected by the first alignment pin be provided with, and described inner conical drogue is fixedly connected in axle by the second alignment pin be provided with.
Further, the external diameter of described end face tapered sleeve need be greater than workpiece diameter.
Further, described axle one end is provided with the shaft shoulder be convenient to opposite end face cone cover and positioned.
Further, the opposite side size of described locking nut must be greater than the external diameter that inner conical drogue is in contact with it end.From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
1, a kind of thin-walled external member Excircle machining fixture of providing of the utility model, by increasing the bearing-surface of workpiece, enhances the rigidity of workpiece.
2, a kind of thin-walled external member Excircle machining fixture of providing of the utility model, the distortion produced when decreasing thin-walled external member clamping, and then the mismachining tolerance reducing that workpiece causes because of distortion.
3, a kind of thin-walled external member Excircle machining fixture of providing of the utility model, eliminates radial clearance and improves positioning precision, can ensure the axiality requirement of inside and outside circle well.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of thin-walled external member of the utility model Excircle machining fixture.
In figure: 1. axle 2. end face tapered sleeve 3. first alignment pin 4. workpiece 5. resilient sleeve 6. inner conical drogue 7. second alignment pin 8. locking nut
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
With reference to figure 1, a kind of thin-walled external member Excircle machining fixture, its structure comprises axle 1 and is sheathed on end face tapered sleeve 2, resilient sleeve 5, inner conical drogue 6 and the locking nut 8 in axle 1 successively from left to right, resilient sleeve 5 and end face tapered sleeve 2 are fixedly connected by the first alignment pin 3, inner conical drogue 6 is fixedly connected in axle 1 by the second alignment pin 7, the external diameter of end face tapered sleeve 2 need be greater than workpiece diameter, axle 1 one end is provided with the shaft shoulder that opposite end face cone cover 2 positions, and the opposite side size of locking nut 8 must be greater than the external diameter that inner conical drogue 6 is in contact with it end.A kind of thin-walled external member Excircle machining fixture that the utility model provides by being arranged with end face tapered sleeve 2 in axle, resilient sleeve 5, inner conical drogue 6, with locking nut 8, first alignment pin 3, second alignment pin 7, thus increase the bearing-surface of workpiece 4, enhance the rigidity of workpiece 4, further, it is larger than workpiece 4 internal diameter by the external diameter of end face tapered sleeve 2 is made, and one end of axle 1 is provided with the shaft shoulder, can well position by opposite end face cone cover 2, the opposite side size of locking nut 8 must be greater than the external diameter that inner conical drogue 6 is in contact with it end, the distortion produced when well can decrease thin-walled external member clamping by such design, and then reduce the mismachining tolerance that workpiece causes because of distortion, and further eliminate radial clearance and improve positioning precision, the axiality requirement of inside and outside circle can be ensured well.
The utility model realizes by the clamping of resilient sleeve expanding structure to thin-walled external member.Operating process is as follows:
(1) fixture is installed
First fixture need be assembled during use, the core parts of this fixture are resilient sleeve 5, axle 1 is equipped with end face tapered sleeve 2 and inner conical drogue 6, wherein inner conical drogue 6 is fixedly connected in axle 1 by the second alignment pin 7, end face tapered sleeve 2 is fixedly connected with resilient sleeve 5 by the first alignment pin 3, finally load onto locking nut 8, just can carry out workpiece 4 clamping afterwards.
(2) dismounting workpiece
Fixture assembly well after, can be sheathed in resilient sleeve 5 by workpiece 4, the end face of workpiece 4 head and end face tapered sleeve 2 is close to, and turns locking nut 8 when making it be moved to the left, and inner conical drogue 6 gives resilient sleeve 5 one radial loads, by workpiece 4 swelling, makes it fix; After machining, turn locking nut 8 in the other direction, the tension force of resilient sleeve 5 is eliminated, thus easily takes off workpiece 4.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
