Abstract

The utility model provides a frock of thin -walled ring spare, including annular jack catch group of a plurality of groups, jack catch group includes the same fan -shaped jack catch of a plurality of radiuses, and fan -shaped jack catch annular is interrupted to be set up, passes through the telescoping device between the adjacent jack catch group and connects, and the mount is installed to one of them the outer tip in the jack catch group at both ends. Because the special construction of thin -walled ring spare, the radial pressure that leads to thin -walled ring spare to receive warp when too big easily, the utility model discloses increased with the area of contact of thin -walled ring spare, the pressure that has disperseed thin -walled ring spare to receive is difficult for leading to the fact the deformation, has increased the telescoping device, increased thin -walled ring spare support in, press from both sides tightly more reliably.

Description

A kind of frock of thin-walled ring
Technical field
This utility model belongs to thin-walled ring frock clamp field, more particularly, to a kind of frock of thin-walled ring.
Background technology
As thin-walled ring poor rigidity, intensity are weak, therefore easily it is deformed in the presence of chuck force, increases part Form error, and then part quality cannot ensure.If directly clamped with the claw of scroll chuck, can be in the effect of chuck force Under slightly become deformation, what is obtained during car hole is cylindrical hole, but when unclamp claw, after removing part, due to elastic deformation it is extensive It is multiple, it is cylindrical to revert to cylinder, and endoporus then becomes rib circle.
During processing circular thin-wall pipe fitting, if pipe fitting is longer, retaining part is too short, then clamp not strongly and lean on.
The content of the invention
In view of this, this utility model is directed to a kind of frock of thin-walled ring, to solve to receive when thin-walled ring is processed Power is yielding, clamps not strongly the technical problem leaned on.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in:
A kind of frock of thin-walled ring, including some groups of annular claw groups, the claw group include some radius identicals Fan-shaped claw, fan-shaped dog rings shape are discontinuously arranged, and are connected by retractor device, in the claw group at two ends between adjacent claw group One of outer end fixed mount is installed.
Further, the retractor device includes some expansion links, and the expansion link includes mobile jib and secondary bar, and mobile jib is Hollow tubular structures, are provided with some radial direction through hole being equally spaced on mobile jib, one end of secondary bar is provided with and radial direction through hole phase The radial elastic device of cooperation, secondary bar be provided with elastic device one end insertion mobile jib inside, on mobile jib away from secondary bar one end It is connected with the end face of fan-shaped claw, connects with the end face of the fan-shaped claw of another claw group away from one end of mobile jib in secondary bar Connect, elastic device is stuck at radial direction through hole, pressure is applied to elastic component, when elastic component is not stopped by radial direction through hole, secondary bar exists Move in mobile jib.
Further, the quantity of the expansion link is three.
Further, the fan-shaped claw is provided with pressure transducer on the medial wall of workpiece, pressure transducer with Controller connects, and pressure transducer is used for the clamping force for detecting claw, prevents pressure excessive.
Further, the quantity of the fan-shaped claw is three.
Further, the quantity of the claw group is two.
Further, a fixed mount is connected with each described fan-shaped claw.
Relative to prior art, a kind of frock of thin-walled ring described in the utility model has the advantage that:
(1) due to the special construction of thin-walled ring, cause to be easily deformed when radial pressure that thin-walled ring is subject to is excessive, this Utility model increased the contact area with thin-walled ring, the pressure for having disperseed thin-walled ring to be subject to, and not easily cause deformation, add Pressure transducer, controls the clamping force to thin-walled ring, when the pressure to thin-walled ring is between 0.5-0.6bar, can protect The rough turn circularity < 0.02mm of card thin-walled ring;
(2) structure that claw group is arranged to adjust by this utility model, can be adjusted according to different tubular lengths The length of expansion link, while playing support to thin-walled ring, clamps more reliable.
