Abstract

The utility model relates to a fixture for clamping external threaded shaft and sleeve workpieces. The fixture comprises a sleeve fixture body, a side wall continuous seam penetrating through two end surfaces of the fixture body is arranged on the fixture body, one end of an inner sleeve surface of the fixture body is provided with an internal threaded section matched with an external thread of a workpiece to be machined, the other end of the inner sleeve surface of the fixture body is provided with an unthreaded hole section, the hole diameter of the unthreaded hole section is smaller than the inner diameter of the internal threaded section, and an axial positioning step is formed at the junction of the unthreaded hole section and the internal threaded section. When the fixture is used for clamping the workpiece to be machined, the workpiece is screwed into the threaded sections of the fixture by the aid of the external thread of the workpiece, stopped on the axial positioning step and axially positioned in the fixture by the aid of the axial positioning step, the fixture has a certain radial elastic retraction function as the side wall continuous seam is arranged on the fixture body, and the workpiece can be clamped by elastic retraction of the fixture. When the fixture and a three-jaw or elastic chuck are used for clamping, the three-jaw or elastic chuck clamps the outer surface of the fixture, so that the external thread of the workpiece is intact.

Description

The anchor clamps that are used for clamping external screw thread axle, sleeve workpiece
Technical field
The utility model belongs to metal machining tool fixture technical field, particularly a kind of anchor clamps for clamping external screw thread axle, sleeve workpiece.
Background technology
For outer surface all or major part be axle, the sleeve workpiece of screw thread, when carrying out car, drilling processing inner surface or end face, because outer surface of workpiece is without other reliable clamping positions of locating, if with three-jaw or the direct clamping workpiece outer surface thread of collet part, crush easily external screw thread, and in the man-hour that adds of carrying out to have axial location, such as the shoulder hole of processing work inside, also can't carry out axial location.
The utility model content
The purpose of this utility model provides a kind of anchor clamps for clamping external screw thread axle, sleeve workpiece, utilize this anchor clamps clamping workpiece after, add in car, drilling and can not damage the outer surface of workpiece screw thread man-hour.
For achieving the above object, the utility model adopts following technical scheme: the anchor clamps that are used for clamping external screw thread axle, sleeve workpiece, comprise the sleeve shaped chuck body, offer the sidewall straight joint that connects the chuck body both ends of the surface on the chuck body, one end of chuck body inner sleeve face is the internal thread segment adaptive with the workpiece to be processed external screw thread, the other end is that the aperture is less than the unthreaded hole section of internal thread segment internal diameter, at the intersection formation axial location step of unthreaded hole section and internal thread segment.
The end that internal thread segment is set of described chuck body is provided with from end-face diameter to outward extending flange locating surface.
The end that described unthreaded hole section and internal thread segment boundary are in internal thread segment is provided with escape.
Described sidewall straight joint is the radial sidewalls straight joint.
Described sidewall straight joint extends vertically.
When the anchor clamps clamping that uses the utility model to provide axle to be processed, sleeve workpiece, utilize the external screw thread of workpiece that workpiece is screwed in the anchor clamps thread segment, and stop at axial location step place, utilize the axial location step to realize the axial location of workpiece in anchor clamps, the sidewall straight joint of offering on the chuck body has anchor clamps and receives function in certain radial elastic, can be by receiving clamping work pieces in the elasticity of anchor clamps; These anchor clamps with three-jaw or collet clamping the time, the outer surface of three-jaw or collet clamping fixture, thus guarantee that workpiece is externally threaded intact.
The utility model can utilize the flange locating surface to determine the degree of depth of shoulder hole when the processing work shoulder hole after chuck body arranges the flange locating surface, plays the positioning datum effect when processing and loading clamp.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment 2;
Fig. 4 is the top view of Fig. 3.
The specific embodiment
Embodiment 1: the anchor clamps that are used for clamping external screw thread axle, sleeve workpiece illustrated in figures 1 and 2, it offers the sidewall straight joint 5 that connects the chuck body both ends of the surface vertically on sleeve shaped chuck body 1, this sidewall straight joint radially connects the inside and outside cover face of chuck body, makes chuck body form the opening sleeve with certain elastic tightening function.One end of chuck body 1 inner sleeve face is the internal thread segment 2 adaptive with workpiece to be processed external screw thread length and diameter, the other end is unthreaded hole section 4, the aperture of unthreaded hole section is less than the internal diameter of internal thread segment, intersection in unthreaded hole section and internal thread segment has formed axial location step 3, and the end that is in internal thread segment in both boundaries is provided with the escape 6 for the machining internal thread section, in addition, the unthreaded hole section is set also for providing the cutter relieving space for drill bit or screw tap when processing work endoporus and the workpiece internal thread.When using anchor clamps clamping workpiece to be processed, workpiece screwed in the thread segment and at described axial location step place stop, realizing the axial location of workpiece in anchor clamps, utilize in the elasticity of anchor clamps and receive clamping work pieces.
Embodiment 2: Fig. 3 and the anchor clamps that are used for clamping external screw thread axle, sleeve workpiece shown in Figure 4, the difference of these anchor clamps and embodiment 1 is: the size among the internal thread segment 2 on the chuck body 1 and the diameter of unthreaded hole section 4 and length and the embodiment 1 is different, but its structure is identical, in addition, the end that internal thread segment is set in chuck body is provided with from end-face diameter to outward extending flange locating surface 7, the flange locating surface can be determined the degree of depth of shoulder hole when the processing work shoulder hole, play positioning datum when processing and loading clamp.
When the various embodiments described above are used at lathe, screw in first and want converted products, re-use trombone slide or three-jaw and clamp the screw thread chuck, after machining, take off chuck, screw out workpiece and get final product.
In the various embodiments described above, sidewall straight joint 5 is the radially straight joint that extends vertically, in the specific implementation, this straight joint also can be along extending the both ends of the surface that connect chuck body with axial oblique line in a certain angle, in addition, this straight joint also can be along connecting with radial line direction direction in a certain angle when connecting the inside and outside cover face of chuck body.
In the various embodiments described above, the purpose that escape is set is to be logical screw thread in order to make screw thread in the internal thread segment, escape is not necessary, if the internal thread in the internal thread segment is not logical screw thread, just be provided with screw thread in outer part, and be unthreaded hole by inner part, in such cases escape can be set.The anchor clamps of these two kinds of structures use for dissimilar clamping workpieces.
