Abstract
The utility model discloses a cutting tool collet chuck and belongs to the field of a cutting tool clamping part of a machine tool. The existing cutting tool collet chuck has unstable clamping force. The cutting tool collet chuck comprises a collet chuck body, wherein a central shaft hole which penetrates through the front end surface and the back end surface of the collet chuck body is arranged on the collet chuck body; a group of axial slots which are distributed at the periphery are arranged on the side surface of the collet chuck body; the axial slots are divided into front slots and back slots which are staggered and arranged at intervals; one section, which is close to the back end surface, of each back slot penetrates through the excircle surface of the collet chuck body and the axial hole; one section, which is close to the front end surface, of each front slot penetrates through the outer excircle surface of the collet chuck body and the axial hole; the front section, which is close to the front end surface, of the axial hole is set as a front straight hole; the back section, which is close to the back end surface, of the axial hole is set as a back straight hole; and the bore diameter of the front straight hole is greater than that of the back straight hole, and the difference value between the two bore diameters is equal or less than 0.3mm. The cutting tool collet chuck increases the clamping stability and machining accuracy.
Description
Technical field
The utility model belongs to machine tool clamping parts, especially accompanies the pass with a kind of tool tube.
Background technology
The central shaft hole of conventional tool collet chuck is through hole, because the front and rear sections axis hole aperture of collet chuck is consistent, in the collet chuck holding cutter process, the unstable phenomenon of cutter holding often appears in cutter, affects machining accuracy, has also reduced production efficiency.
The utility model content
The purpose of this utility model is intended to overcome existing a kind of cutter collet chuck and has the little defective of collet chuck chucking power, and a kind of a kind of collet chuck with continual and steady holding cutter is provided.
For this reason, the utility model is by the following technical solutions: a kind of cutter collet chuck, comprise collet chuck body, be provided with the central shaft hole that connects its front end face and rear end face on the collet chuck body, described collet chuck body side is provided with the axial slot of one group of circle distribution, axially slot is divided into rear slot and front slot, rear slot and front slot interleaved arrange, rear slot is near one section perforation collet chuck body periphery and the described axis hole of rear end face, front slot is near one section perforation collet chuck body periphery and the described axis hole of front end face, it is characterized in that, described axis hole is set to front straight hole near the leading portion of front end face, described axis hole arranges rear straight hole near the back segment of rear end face, and the aperture of described front straight hole is greater than the aperture of rear straight hole, and the difference in two apertures is equal to or less than 0.3mm.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described collet chuck body is Rotary-table shape shrinking section near the part of front end face, part near rear end face is Rotary-table shape gripping section, the collet chuck body front end face is the minor diameter end face of shrinking section, the collet chuck body rear end face is the minor diameter end face of gripping section, is provided with annular groove on the collet chuck body periphery between shrinking section and the gripping section.
Use the utility model can reach following beneficial effect: the utility model is controlled at the difference in two stage apertures of axis hole and is less than or equal to 0.3mm, so that the stress non-continuous event is little during urgent clamping, the not yielding and skew in the aperture of axis hole, can stablely continue holding cutter, improve machining accuracy.
