Abstract
The invention relates to a clamping device. A turning clamp comprises an outer diameter clamp and an inner diameter clamp, wherein the outer diameter clamp comprises a hollow inner diameter machining mould, the inner surface of the inner diameter machining mould is provided with a part positioning groove, the two ends of the inner diameter machining mould are respectively provided with a hard rubber groove, hard rubber is arranged in each hard rubber groove, and the inner side of each piece of hard rubber is respectively provided with a bolt perpendicular to the central shaft of the outer diameter clamp; the inner diameter clamp comprises a hollow outer diameter machining mould, the outer surface of the outer diameter machining mould is provided with a part positioning groove, the two ends of the outer diameter machining mould are respectively provided with a hard rubber groove, hard rubber is arranged in each hard rubber groove, and the inner side of each piece of hard rubber is respectively provided with a bolt perpendicular to the central shaft of the outer diameter clamp. According to the turning clamp, the original positioning mode and the direction of the clamping force are not changed, the point bearing mode (three claw clamping force is applied at three points) of the original bearing clamping force is changed into the face bearing mode (the hard rubber applies force on the circumference of a workpiece), and the turning clamp is applied to products with the size diameter smaller than or equal to 500 mm.
Description
Technical field
The present invention relates to a kind of clamping device.
Background technology
In recent years, on market, the description and quantity of processing thin-walled bearing ring is more and more, and the lasso size processing with traditional installation way has been difficult to meet the designing requirement of product, after the processing of some parts, on lathe, do not unclamp fixture and measure indices and can reach Design Requirement Drawing, and often size is seriously overproof while measuring behind part disengaging position location.Tracing it to its cause, is mainly because workpiece wall is thin, easily stress deformation.If clamping point does not overlap with the anchor point of workpiece, the workpiece of completion of processing is after clamping force is removed, and the internal stress effect that can cause the middle folder power of workpiece because of process produces strain, makes
Become workpiece size before and after clamping force is removed inconsistent.
Summary of the invention
The present invention aims to provide a kind of workpiece machining clamp that can eliminate the inconsistency of workpiece processing rear removal clamping force front and back size.
Workpiece machining clamp of the present invention, comprise external diameter binding clasp and internal diameter binding clasp, wherein said external diameter binder comprises the internal diameter machining mould of hollow, its inner surface is provided with part detent, and two ends are respectively provided with a vulcanie groove, in it, be equipped with vulcanie, the inner side of each vulcanie is equipped with one perpendicular to the bolt of external diameter binder central shaft; Described internal diameter binding clasp comprises the external diameter machining mould of hollow, its outer surface is provided with part detent, and two ends are respectively provided with a vulcanie groove, are equipped with vulcanie in it, the inner side of each vulcanie is equipped with one perpendicular to the bolt of external diameter binder central shaft.
The present invention does not change former locate mode and clamping force direction, (three-jaw clamping force is 3 points) face of changing into that the former point of accepting clamping force is accepted accepts that (vulcanie is to workpiece, press on periphery), this type of fixture is applicable to the product of size diameter≤500 mm.
