Description
Technical field
It the utility model is related to a kind of thin-walled end-cap fixture.
Background technology
Thin-walled end cap is made up of relatively thin annular stile and panel, when needing punching on stile or face, typically will
End cap punches fixed to scroll chuck, and it is that stile is buckled on chuck jaws to be fixed using scroll chuck, is then displaced outwardly card
Pawl, stile is expanded outwardly to fix using claw, but because stile is relatively thin, easily deformed stile tension in expansion；This
Outside, when fixing punching end cover using claw, because stile is narrower and the limitation of claw height so that rubbing between stile and claw
It is smaller to wipe power, when causing the drilling machine to drill stile, end cap vibrates with bit, when vibration can cause drilling, hole
Edge is front and rear to hit drill bit, causes to portal in irregular shape；On the other hand, when panel and stile are required for drilling, due to panel with
Stile is to be mutually perpendicular to, so the Drilling operation of counter plate and stile could be completed by having to clamping twice in drilling, is added
Workload, reduce borehole accuracy.
The content of the invention
The technical problem that the utility model solves is to provide a kind of thin-walled end-cap fixture, and thin-walled end cap can be entered
