Abstract
The utility model relates to a numerically controlled lathe mandrel positioning fixture, which comprises a positioning mandrel, an opening pressing plate and a flanged nut. The numerically controlled lathe mandrel positioning fixture is characterized in that the positioning mandrel is a stepped shaft. One end of the positioning mandrel is equipped with a positioning column and a stud. The dimension of the outer periphery of the positioning column is 0.01-0.02 mm smaller than the dimension of the inner hole of a part to be machined. The other end of the positioning mandrel is equipped with a clamping shaft. The numerically controlled lathe mandrel positioning fixture has the advantages of simple structure, easy manufacturing and convenient and fast clamping, which improves the machining efficiency. The numerically controlled lathe mandrel positioning fixture is suitable for the clamping and positioning of parts, especially parts with larger hole diameters. Due to the adoption of the numerically controlled lathe mandrel positioning fixture, the radial compaction deformation of thin-walled parts is reduced and the coaxial precision of the internal and external peripheries of parts is high.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of numerically controlled lathe axle positioning fixture.
Background technology
At mechanical processing industry, need processing inside and outside circle high-axiality, yielding thin-wall product to be seen everywhere.Processing method is now: soft pawl clamping part cylindrical machines part endoporus and clamping of cylindrical.For the good part of wall thickness intensity, like this internal-external circle concentricity of product processed can accomplish fine, but for the yielding part of thin-walled, the internal-external circle concentricity difference of product processed will be very big like this, and working (machining) efficiency is also low.Be mainly used in the soft pawl clamping processing of numerically controlled lathe inside and outside circle high-axiality, yielding thin-walled parts.
Summary of the invention
The purpose of the utility model overcomes the existing shortcoming of above-mentioned technology exactly, provides a kind of simple in structure, low cost of manufacture, part deformation little, easy to use, the numerically controlled lathe axle positioning fixture that machining accuracy is high.
The numerically controlled lathe axle positioning fixture of the utility model comprises apotting spindle, opening pressing plate and band shoulder nut; It is characterized in that: described apotting spindle is the step axle; One end is provided with positioning cylinder and double-screw bolt; The other end is provided with clamp axis, and the positioning cylinder excircle dimension is than the little 0.01-0.02mm of hole dimension in the processing parts.
The numerically controlled lathe axle positioning fixture of the utility model is simple in structure; Easy to manufacture, the clamping that can be fit to aperture
even more wide-aperture part is located.The distortion of thin-walled parts radial compaction is little, the internal-external circle concentricity precision high, and convenient mounting and clamping is quick, has improved working (machining) efficiency.
Description of drawings
Accompanying drawing is the structural representation of this practical numerically controlled lathe axle formula positioning fixture.
Among the figure: 1, apotting spindle, 2, the opening pressing plate, 3, band shoulder nut, 4, workpiece, 5, positioning cylinder, 6, double-screw bolt, 7, clamp axis.
The specific embodiment
The numerically controlled lathe axle positioning fixture of the utility model comprises apotting spindle 1, opening pressing plate 2 and band shoulder nut 3.Its apotting spindle 1 is the step axle, and an end is provided with positioning cylinder 5 and double-screw bolt 6, and the other end is provided with clamp axis 7, and positioning cylinder 5 excircle dimensions are than the little 0.015mm of hole dimension in the processing parts.
During use, at first the clamp axis 7 with apotting spindle 1 clips on the good scroll chuck of numerically controlled lathe boring, needs the workpiece 4 of processing to be sleeved on the positioning cylinder 5 of apotting spindle 1.For convenient mounting and clamping, fall 30 ° of chamferings on the positioning cylinder 5, about length 2mm, load onto opening pressing plate 2, the band shoulder nut 3 on the double-screw bolt 6 of screwing, with workpiece 4 axial compression on apotting spindle 1.Guarantee that workpiece 4 is indeformable, the coaxial accuracy of the Workpiece internal-external circle that processes is high.
