Abstract

The utility model provides an expansion clamp which is characterized by mainly comprising a base, a supporting ring, expansion blocks, a cover plate, a cone block, a spring, a stop pin, a nut and a mandrel, wherein the supporting ring and the mandrel are fixed on the base; the expansion blocks are arranged on the supporting ring; the cover plate presses the upper surfaces of the expansion blocks, and is fixed on the supporting ring; a slideway for the expansion block is defined by the cover plate and the supporting ring; two or more than two expansion blocks form a ring-shaped structure; the number of expansion blocks is increased as the diameter of a part generally increases; each expansion block is pushed towards the center by the spring propped against the stop pin; the stop pin is inserted in the supporting ring; and the cone block is arranged in the center of the expansion block, is sleeved on the mandrel, and is pressed by the nut. The expansion clamp has the advantages that the operation is convenient, the processing deformation of thin-walled parts can be effectively controlled, and the processing quality of the parts is improved to a certain degree.

Description

A kind of swelling anchor clamps
Technical field
The utility model relates to jig.
Background technology
Thin-walled parts is typical weak hard parts; Relative rigidity is lower; Intensity a little less than; Processing technology is poor, and particularly under to part shape, dimension precision requirement condition with higher, they are all very responsive to vibration, cutting force and cutting temperature etc.; Adopt the processing of ordinary machine tool anchor clamps; Easy deformation with produce vibration, wayward machining accuracy with improve working (machining) efficiency, process more difficult during particularly approaching final processing dimension.
Summary of the invention
The purpose of the utility model is to provide a kind of can improve the jig that the thin-walled parts distortion improves part processing precision effectively.
The utility model provides a kind of swelling anchor clamps, it is characterized in that: mainly comprise base, gasket ring, bloated piece, cover plate, cone piece, spring, backing pin, nut and mandrel, gasket ring and mandrel are fixed on the base; Bloated piece places on the gasket ring, pushes down with cover plate above the bloated piece, and cover plate is fixed on the gasket ring; Cover plate and gasket ring form the slideway of the piece that expands; By the piece looping that expands more than 2 or 2, the quantity of the piece that expands generally increases with the increase of diameter of part, and every spring that is all withstood on the backing pin is pushed the center to; Backing pin inserts in the gasket ring, and the cone piece places the piece center hub that expands on mandrel, to push down with nut.
During use, fastening nut drives the cone piece and moves downward, and the piece that expands is outwards slided, and compresses the part internal diameter.
The swelling anchor clamps that the utility model provides can have locating ring on its base, so as on lathe the position of centering base.
The swelling anchor clamps that the utility model provides, its advantage is: easy to operate, control the machining deformation of thin-walled parts effectively, make the part processing quality obtain certain raising.
Description of drawings
Fig. 1 is the structural representation of swelling anchor clamps.
The specific embodiment
Embodiment 1
The swelling anchor clamps, its structure is as shown in Figure 1, comprises base 1, gasket ring 3, bloated piece 4, cover plate 5, cone piece 6, spring 7, backing pin 8, nut 9 and mandrel 10; Gasket ring 3 is fixed on the base 1 with mandrel 10, and locating ring 2 is arranged on the base 1, and the piece 4 that expands places on the gasket ring 3; Expand and push down with cover plate 5 above the piece 4, cover plate 5 is fixed on the gasket ring 3, and cover plate 5 and gasket ring 3 form the slideway of the piece 4 that expands; By 6 bloated piece 4 loopings; Every spring 7 that is all withstood on the backing pin 8 is pushed the center to, and backing pin 8 inserts 3 li of gasket rings, and cone piece 6 places piece 4 center hub that expand on mandrel 10, to push down with nut 9.

Claims (2)
