Abstract
The utility model relates to a broach structure of a high-speed ball machine spindle, in particular to a fixation structure used between a high-speed spindle cutter handle and a spindle of a machining machine tool. According to the utility mode, a claw pulling seat (1) is provided with an axially interpenetrated air channel, and the inner wall of a mandrel (6) and the radial contact part of a pull claw (4) are of conical surfaces. The broach structure of the high-speed ball machine spindle is convenient to use. The automatic broach assembly and disassembly can be realized by virtue of the external broach pulling force, the automatic dust blowing can be realized, the automatic dust blowing and the cleaning on the interior of the structure can be realized by virtue of external air sources, and most contact surfaces are of the conical surfaces, so that the broach structure is favorable in jumping precision in a rotating process. The broach structure is suitable for high-speed spindles and has the advantages of simplicity and compactness in structure, long service life and the like.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind ofly is used between mechanical processing machine high-speed main spindle handle of a knife and main shaft fixing structure.
Background technology
In the prior art, the main spindle broach complex structure, pull bar and broaching tool respective outer side edges power are lower, are difficult to realize the automation of loading, unloading cutter, even there is the peripheral hardware all can not be to inner drifting dust, service life be short.
Summary of the invention
The utility model relates to a kind of broaching tool structure of ball high speed machine main shaft, and it has overcome the deficiency of prior art.
The utility model technical solution is to include axle (6); The inner chamber of axle (6) is provided with pulling claw seat (1); Pulling claw seat (1) bottom fixes through elastic cylinder pin (3) and pulling claw (4), and the top of pulling claw (4) is provided with extension spring (2), and the lower jaw place of pulling claw (4) is fixed with handle of a knife (5); The utility model particularly pulling claw seat (1) is provided with the air flue of axial perforation, and the inwall of axle (6) and pulling claw (4) radially are the conical surface in the contact position.
The utility model operation principle is that pulling claw also moves down thereupon when the pulling claw seat moves down, and because the contraction of extension spring, pulling claw opens; Along with the increase of displacement is opened bore and is also increased thereupon, when the blind rivet external diameter of bore, when pulling claw seat following terminates to the upper surface of blind rivet simultaneously greater than handle of a knife; Handle of a knife comes off, and accomplishes the process of forging a knife, otherwise; With the handle of a knife axle of packing into, pulling claw seat and pulling claw move up, and the pulling claw bore dwindles; The conical surface of pulling claw and the conical surface of blind rivet are fitted, and tension, accomplish dress cutter process.The external world provides source of the gas, and the central airway center roller through the pulling claw seat carries out drifting dust, cleaning
The advantage of the utility model is:
1, easy to use, can realize adorning automatically cutter and unload cutter by the broach force in the external world.
2, can realize automatic drifting dust, by extraneous source of the gas to the automatic drifting dust of this inside configuration, cleaning.
3, mostly each contact-making surface is the conical surface, thereby makes this structure in rotary course, possess the precision of well beating, and is fit to high-speed main spindle;
4, have advantages such as simple and compact for structure, life-span length.
