Abstract
This utility model is related to one kind for thin-walled rotary part anti-deformation clamp for machining, belongs to cutting technology field.Clamp body Dingan County is mounted on the three-jaw chuck of lathe during turning workpiece excircle, workpiece is sleeved on clamp body, and gap coordinates；By bolt and nut, the conical surface of cone is interacted with the conical surface of elastic ring, is made elastic ring swell to its cylindrical and workpiece inner cylinder face and is in close contact, and compared with prior art, its remarkable advantage is this utility model：Thin-walled rotary part processing rigidity is enhanced, reduces its clamping and cutting deformation, it is ensured that machining accuracy.
Description
Technical field
The invention belongs to metal parts Machining Technology for Cutting field, is related to a kind of special " thin-walled rotary part anti-deformation
Clamp for machining ".
Background technology
General slewing parts size is generally processed on lathe using clamping with three-jaw chuck.
Thin-walled rotary part as shown in Figure 1, during the polish D surfaces of revolution, as parts fixation deforms and cuts
Power causes work pieces process to deform, and the size and Form and position error for making part is larger, qualification rate is relatively low.
The content of the invention
The invention aims to solve the problems, such as that thin-walled rotary part mismachining tolerance is big, and a kind of turning for providing is special
Use fixture.
Realize that technical solution of the invention is：Clamp body (1) is fixedly mounted on the three-jaw chuck of lathe, workpiece
(2), elastic ring (4), cone (3), pressing plate (5), packing ring (7) are fixedly connected by the screw rod and nut of clamp body (1).
Workpiece (2) is sleeved on clamp body (1), and ensures that gap coordinates, and elastic ring (4) is placed in workpiece (2), and cone (3) is placed on bullet
Property circle (4) in, pressing plate (5), packing ring (7) are sequentially sleeved on the screw rod of clamp body (1), nut (6) is connected with clamp body (1) screw thread
Connect.As nut (6) is screwed, cone is axially moveable elastic ring to be supportted to the inner cylinder face with workpiece thin-walled and is brought into close contact, and increases
The rigidity of big workpiece, reduces clamping deformation and cutting deformation, so as to improve the machining accuracy of part.
Compared with prior art, its remarkable advantage is the present invention：Elastic ring and workpiece Multi-contact, form multiple spot clamping,
Clamping deformation and cutting deformation are significantly reduced than 3 points of traditional installation way.
Description of the drawings
Fig. 1 is original thin-wall case work pieces process schematic diagram；
Fig. 2 is using the fixture machining sketch chart (parts of thin-wall casing clamp for machining structure chart)；
Fig. 3 is the elastic ring structure chart in the device
In figure, clamp body 1, workpiece 2, cone 3, elastic ring 4, pressing plate 5, nut 6, packing ring 7.
Specific embodiment
Clamp body 1 is arranged on the three-jaw chuck of lathe, and workpiece 2 is sleeved on clamp body 1, and ensures that gap coordinates, bullet
Property circle 4 is placed in workpiece 2, and cone 3 is placed in elastic ring 4, and pressing plate 5, packing ring 7 are sequentially sleeved on the screw rod of clamp body 1, nut
6 are threadedly coupled with clamp body 1.
Nut 6 is tightened, the side shifting to the left of cone 3 is promoted by packing ring 7, pressing plate 5, it is outer that 3 conical surface of cone expands elastic ring 4
Rise, until the inner cylinder face of external cylindrical surface and the workpiece 2 of elastic ring 4 is in close contact, and keep certain pressure, workpiece 2 and elasticity
Maximum static friction force between circle 4 be enough to resist cutting force.Then carry out the external cutting processing of workpiece 2.
After the external cutting of workpiece 2 is machined, nut 6 is screwed off, remove packing ring 7, pressing plate 5 and cone 3 successively, elasticity
Circle 4 recovers ortho states, and from workpiece, 2 remove, then remove workpiece 2, and the operation is completed.Prepare the processing of next workpiece.
Claims (1)
