Description
Technical field
The invention belongs to machining equipment technical field, the fixation metal of specifically a kind of metal tubular work pieces process
The tooling of pipe, especially structure novel, a kind of quick inner support expansion set tubular workpieces fixture easy to use and its application method.
Background technology:
Have a kind of fixture of inner support expansion set structure in tubular workpieces process operation at present, usually utilize nut, screw thread and
The center-pole of limited block stretching device realizes the operation of collet clamps workpiece.When clamping work piece operations, nut, screw thread are utilized
It in cinching process, needs additionally to use spanner rotating nuts, the operating process time is long, and other personnel is needed to grasp jointly
Make, often the clamping dynamics of workpiece is not easy to support and hold, and it is insufficient that there are clamping dynamics, and work piece falls off spends greatly with clamping force, work
Situations such as part is damaged.Therefore, it suddenly waits proposing a kind of improved structure, using more convenient and efficient, shortens the clamp operation time, intensifying force
Degree is accurate, and clamping is stablized, not only will not working loose, but also will not defective work piece tubular workpieces process equipment.
Invention content
The present invention in order to solve the above technical problems, provides a kind of quick inner support expansion set tubular workpieces fixture and its use
Method.The fixture uses the stretching structure of eccentric cam, flexible inner support expansion set chuck structure to well solve inner support expansion set
Collet quickly open, consolidate workpiece operation.With simple in structure, it is easy to make, it is easy to use, the characteristics of highly effective and safe.
And the processing tool of a variety of caliber workpiece can be widely applicable for.
The present invention takes following technical scheme：
A kind of quick inner support expansion set tubular workpieces fixture is equipped with collet, outer tube, center-pole and tensile part, feature
It is：The collet is made of elastic metallic material, is the thick intermediate thin short cylindrical shape in both ends, that is, thick section before being divided into, middle thin segment, after
Thick section；Preceding thick section is divided into several valves, and cracking between valve extends to middle thin segment rear end, and the end cracked is equipped with circular hole, and rear butt end is one
A seamless entirety, entire collet axial centre are a cavity；It is a funnel-shaped opening at the front end face center for being divided into several valves；
It is equipped with the ladder section of reduced outside diameter in the front end of preceding thick section, outer diameter and the processing pipe fitting internal diameter of the ladder section coincide, the ladder
The outer diameter of thick section part is identical or slightly larger as the outer diameter of tubular workpiece before section is subsequent, is set on the outside of the front end face of the ladder section
There is chamfering；The middle thin portion of collet is that diameter is smaller 2-4cm than the diameter of preceding thick section and rear thick section；In the rear end of the rear thick section of collet
Ladder section after head sets one, the outer diameter of the rear ladder section match with the internal diameter of the outer tube, and the front port of outer tube is just
It is inserted in the rear ladder section, and is fixed together；It is equipped with a fixed follower head in the rear port of outer tube, is set outside the follower head
Have a compression spring, gasket be equipped with outside compression spring, be equipped with open-work among the follower head, compression spring and gasket, the center-pole pass through the gasket,
Compression spring, follower head, outer tube, and penetrate the middle cavity of the collet, the front end of the center-pole set there are one it is outer it is thick in it is thin
Sphenocephaly, the sphenocephaly match with the funnel-shaped hole at collet front end face center；It is fixed with one in the rear end of center-pole
A eccentric cam seat, if there are one sides there are one the eccentric cam of plush copper, which can be rotated by a central shaft
Ground is fixed on eccentric cam seat, and eccentric cam is equipped with the driving part for driving its rotation；Under driving part driving, plush copper turns
To and when withstanding gasket, pull center-pole to move back, center-pole pulls collet to move backward by its front end sphenocephaly, in housing
The support force and center-pole of pipe by front end sphenocephaly under the pulling force effect of collet front end face center funnel-shaped hole, collet
Divide valve distending, the elastic force that distending generates that collet is held out against pipe fitting is processed；The setting of the forward and backward ladder section of collet can be controlled effectively
The straightness of system processing pipe fitting and fixture, collet divide valve root circular hole that can prevent stress concentration, the setting of circular hole and it is described in
