Abstract
The utility model belongs to machining frock field, in particular to an eccentric anchor clamps that is used for hollow shaft class piece excircle to process, including rising by child and dabber, the dabber is eccentric dabber, the dabber with the child disalignment rises, the dabber with the eccentricity of child of rising is 1-1.25mm. The utility model provides a simple and practical, reduce to export an eccentric anchor clamps that is used for hollow shaft class piece excircle to process of deviation.
Description
Technical field
The utility model belongs to machining frock field, particularly a kind of eccentric fixture for hollow shaft like members Excircle machining.
Background technology
Process the outer bowlder in some elongated hollow shaft forgings (aperture: 50mm ~ 100mm), need Internal hole positioning turning, what Internal hole positioning adopted is plug, and plug as shown in Figure 1.And due to the outlet that causes during boring partially comparatively large, during turning under the condition ensureing Wall-Thickness Difference, cylindrical car could be shown in light by the copper sheet that need pad several millimeters between expander and mandrel, easy changing of the relative positions during pad copper sheet.
Summary of the invention
The purpose of this utility model is that overcoming above-mentioned deficiency of the prior art provides a kind of simple and practical, poor eccentric fixture for hollow shaft like members Excircle machining required of guarantee workpiece.
The technical solution of the utility model is achieved in that a kind of eccentric fixture for hollow shaft like members Excircle machining, comprise expander and mandrel, described mandrel is eccentric mandrel, described mandrel and described expander disalignment, and the eccentricity of described mandrel and described expander is 1 ~ 1.25mm.
The good effect that the technical solution of the utility model produces is as follows: mandrel of the present utility model and expander decentraction, mandrel and expander eccentric throw are 1 ~ 1.25mm, when workpiece outlet is partially larger, cylindrical car not bowlder, height point can be put into the thin position of workpiece wall, after on top top, under the requirement ensureing workpiece difference, excircle of workpiece car circle be shown in light, very easy to use, and the changing of the relative positions can not improve quality and the production efficiency of product.
Accompanying drawing explanation
Fig. 1 is expander and the coaxial stopper structure schematic diagram of mandrel in prior art.
Fig. 2 is the utility model expander and mandrel out-of-alignment eccentric fixture structural representation.
Fig. 3 is the structural representation of the utility model mandrel.Be labeled as in figure: 1, expander; 2, mandrel.
Detailed description of the invention
A kind of eccentric fixture for hollow shaft like members Excircle machining, as shown in Figure 2,3, according to the diameter of the different endoporus of hollow shaft like members, design eccentric automobile-used plug, this eccentric fixture comprises expander and mandrel, and mandrel is made eccentric, with expander decentraction, eccentric throw is 1 ~ 1.25mm, and the diameter dimension φ D of expander is identical with the hole size of workpiece, and car is evenly cut into three parts after being shaped.
During use, automobile-used plug is loaded in the endoporus of workpiece two ends, the conical bore portion of the upper mandrel in top tightly top, then by expander rising top tight workpiece bore area, by Workpiece clamping.Because mandrel is made eccentric, with expander decentraction, bias is 1 ~ 1.25mm, when workpiece outlet is partially comparatively large, cylindrical car not bowlder, can be put into the thin position of workpiece wall by height point, after on top top, under the requirement ensureing workpiece difference, excircle of workpiece car circle is shown in light, very easy to use.
