Abstract

The utility model relates to a broach mechanism of a ball high-speed motorized spindle, in particular to a mechanism for fixing a high-speed spindle tool handle and a spindle of a mechanical working machine tool. A sliding core (2) and a pull rod (3) are fixed at a contact position, and radial contact positions of the sliding core (2) and a pull jaw (1) are conical surfaces. The broach mechanism can generate larger broach force by making full use of the pulling force of the pull rod, energy consumption is reduced so that energy is saved, higher rotary bounce precision can be provided when the spindle is operated, and the broach mechanism is simple and compact in structure, long in service life and convenient in popularization and application.

Description

A kind of tool-broaching mechanism of ball high-speed electric main shaft

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 mechanism.

Background technology

In the prior art, in the main spindle broach mechanism, pull bar and tool-broaching mechanism coordinate force are lower, thus pull bar often need bigger pulling force to upper pulling force, therefore cause unnecessary energy consumption, and existing tool-broaching mechanism can not provide the precision in the reasonable rotation.

Summary of the invention

The utility model relates to a kind of tool-broaching mechanism of ball high-speed electric main shaft, the pulling force that it can make full use of pull bar makes tool-broaching mechanism produce bigger broach force, the saving energy cuts down the consumption of energy, and when working, main shaft can provide the higher rotation precision of beating, long service life simple and compact for structure is convenient to promote and use.

The utility model technical solution is in existing pulling claw (1), slide cores (2), pull bar (3), jackscrew (4), handle of a knife (5), on the basis of axle core (6), the utility model particularly slide cores (2) fixes in the contact position with pull bar (3), and slide cores (2) radially is the conical surface in the contact position with pulling claw (1).

More than pulling claw described in the utility model (1) with the axle core (6) a radially contact position be the conical surface.

The head outer wall of slide cores described in the utility model (2) inwall and pull bar (3) is fixed by screw thread.

The utility model operation principle is, when pull bar (3) was applied in a tensile force f that makes progress, pull bar (3) moved upward, slide cores (2) because and between the pull bar screw thread fix, move upward thereupon.Because the contact-making surface between slide cores (2) and the pulling claw (1) is the conical surface, pulling claw (1) also is the conical surface with the contact-making surface of axle core (6) inside simultaneously, and pulling claw (1) produces slope climbing movement radially.Thereby make pulling claw (1) bottom contact and strain handle of a knife (5) with handle of a knife (5) inner chamber.

Advantage of the present utility model is:

1, owing to make moving upward of pull bar be converted into the radially slope climbing movement of pulling claw, thereby makes pulling force obtain amplifying, act on less power of pull bar and can produce bigger broach force, save energy consumption by this structure.

2, each contact-making surface is the conical surface, thereby makes this structure possess the precision of well beating in rotary course, is fit to high-speed main spindle.

3, have simple and compact for structure, long service life.
