Abstract

The utility model relates to a finish machining fixture for thin-wall parts, which is characterized by comprising a cylindrical main body and an O ring, wherein the end cover on one end of the main body is provided with a connecting handle, and the inner wall of the other end of the main body is connected with a compaction thread disk through threads; the center of the compaction thread disk is provided with an axial machining through hole; the bore of the main body forms a clearance fit with the outer race of the O ring and the outer race of the workpiece; and the diameter of the machining circular hole of the compaction thread disk is identical to the bore diameter of the O ring and greater than the bore diameter of the workpiece. When in use, the connecting handle on the main body is firstly connected with the main shaft of the machine tool, the workpiece and the O ring are alternately fed into the inner cavity of the main body, and the compaction thread disk is finally screwed in, so that the machining cutter carries out finish machining on the workpiece through the machining circular hole in the compaction thread disk; and after machining, the compaction thread disk is loosened, and the O ring and the workpiece are taken out. The workpiece is axially clamped by the O ring to reduce the clamping deformation of the workpiece; and the finish machining fixture for thin-wall parts has the advantages of high clamping reliability and high production efficiency, satisfies the machining requirement of high precision, and can be used for simultaneously carrying out finish machining on multiple workpieces.

Description

A kind of thin-wall part fine finishining anchor clamps

Technical field

The utility model relates to a kind of mechanical grip instrument, particularly a kind of thin-wall part fine finishining anchor clamps.

Background technology

At present, when carrying out as fine finishining such as inner hole grinding, turning to thin-wall part, generally adopt in the radially clamping of excircle of workpiece added resilience cover or with the scroll chuck method of clamping and fix, make workpiece produce the clamping distortion easily, machining accuracy is difficult to guarantee that production efficiency is low.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned weak point, and provides a kind of clamping reliable, satisfies the high accuracy processing request, the thin-wall part fine finishining anchor clamps that production efficiency is high.

The purpose of this utility model is achieved in that a kind of thin-wall part fine finishining anchor clamps, it is characterized in that it comprises cylindrical-shaped main body, O type circle, on the main body one end end cap connection handle is arranged, the connection of main body other end inner thread compresses the silk dish, compress a disk center and have axial processing circular hole, main body endoporus and O type circle outer ring, workpiece outer ring matched in clearance, compress silk dish processing circular hole consistent with O type circle diameter of bore, greater than the workpiece diameter of bore.

The utility model is owing to adopt above design, during use, earlier with the connection handle on the main body with after the machining tool main shaft is connected, again workpiece, O type circle are alternately packed in the main body inner chamber, be screwed at last that to compress silk dish tight with work piece positioning, process tool carries out fine finishining by a processing circular hole that compresses on the silk dish to workpiece, after processing, unclamp and compress silk dish, taking-up O type circle and workpiece.By O type circle workpiece is carried out axial clamping, reduce the clamping distortion of workpiece, clamping is reliable, satisfies the high accuracy processing request, can carry out fine finishining to a plurality of workpiece simultaneously, the production efficiency height.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of thin-wall part fine finishining anchor clamps, comprise cylindrical-shaped main body 2, O type circle 4, on the end cap of main body 2 one ends by the bolt flexible connection connection handle 1 is arranged, the connection of main body 2 other end inner threads compresses silk dish 3, compress silk dish 3 centers and have axial processing circular hole, the H8/f7 matched in clearance press in main body 2 endoporus and O type circle 4 outer rings, workpiece outer ring, compress silk coil 3 process circular holes consistent with O type circle 4 diameter of bores, greater than the workpiece diameter of bore.
