Abstract

The utility model provides a kind of adjustable fixer of numerical control machine tool cutting cutter, comprise handle of a knife, knife bar, handle of a knife is tapered, knife bar passes through the conical surface gradient pressure fixing of handle of a knife in handle of a knife, one end of handle of a knife is provided with blind rivet, the circumferential surface of the other end evenly on four tapering screws are installed.The adjustable fixer of this kind of numerical control machine tool cutting cutter can lock cutter firmly by four tapering screws that handle of a knife is arranged, can longer time, more stably adapt to High Rotation Speed, and tapering screw is compared other screws and can is fixed on handle of a knife better, be not easy the high-speed rotary along with handle of a knife then loosen; In addition, four tapering screws can be finely tuned cutter, make it can micro-deflection different directions, process special hole size, decrease and process because of cutter the deviation that causes for a long time and carry out the time that cutter readjusts, reduce tool changing frequency, ensure that crudy better, substantially increase operating efficiency.

Description

A kind of adjustable fixer of numerical control machine tool cutting cutter

Technical field

The utility model relates to a kind of fixture of numerical control machine tool cutting cutter.

Background technology

Conventional Digit Control Machine Tool is generally the knife bar being fixed cutting tool by taper handle of a knife, thus fixing cutting tool, the top of handle of a knife arranges blind rivet, thus enable the claw on lathe hold handle of a knife securely, the axiality of handle of a knife is consistent with the axiality of machine tool chief axis, ensure stable processing, and make it be clamped at better in lathe, taper handle of a knife is a kind of very accurate machining tool, carry the rotary motion of main shaft and transmission of torque in whole working angles to the substantial responsibility of cutting tool, its quality requirement is extremely strict, even very small error, also the final mass of workpiece to be machined will directly be had influence on.Although current taper handle of a knife can allow cutter adapt to Digit Control Machine Tool High-speed machining, but cutter can only lean on conical surface gradient Prssure lock stationary knife bar, so not only have slight loosening after High Rotation Speed operation a period of time, and when encountering clamping boring cutter class cutter, can not micro-positioning regulators position.

Utility model content

For solving the problem, the utility model provides a kind of adjustable fixer of numerical control machine tool cutting cutter, and its technical scheme adopted is as follows:

A kind of adjustable fixer of numerical control machine tool cutting cutter, comprise handle of a knife, knife bar, handle of a knife is tapered, knife bar, be is characterized in that: one end of described handle of a knife is provided with blind rivet by the conical surface gradient pressure fixing of handle of a knife in handle of a knife, the circumferential surface of the other end evenly on four tapering screws are installed, knife bar is tightly locked in handle of a knife by tapering screw, but also can the position of fine-adjustable tool bar, make cutter can micro-deflection different directions, process special hole size.

By the realization of technique scheme, the adjustable fixer of numerical control machine tool cutting cutter provided by the utility model can lock cutter firmly by four tapering screws that handle of a knife is arranged, can longer time, more stably adapt to High Rotation Speed, and tapering screw is compared other screws and can is fixed on handle of a knife better, be not easy the high-speed rotary along with handle of a knife then loosen; In addition, four tapering screws can be finely tuned cutter, make it can micro-deflection different directions, process special hole size, decrease and process because of cutter the deviation that causes for a long time and carry out the time that cutter readjusts, reduce tool changing frequency, ensure that crudy better, substantially increase operating efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the profile along A-A direction in Fig. 1.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of adjustable fixer of numerical control machine tool cutting cutter, comprise handle of a knife 1, knife bar 2, handle of a knife 1 is tapered, and knife bar 2 passes through the conical surface gradient pressure fixing of handle of a knife 1 in handle of a knife 1, and one end of handle of a knife 1 is provided with blind rivet 3, the circumferential surface of the other end evenly on four tapering screws 4 are installed, knife bar 2 is tightly locked in handle of a knife 1 by tapering screw 4, but also can the position of fine-adjustable tool bar 2, makes cutter can micro-deflection different directions.

Claims

1. the adjustable fixer of a numerical control machine tool cutting cutter, comprise handle of a knife, knife bar, handle of a knife is tapered, knife bar passes through the conical surface gradient pressure fixing of handle of a knife in handle of a knife, it is characterized in that: one end of described handle of a knife is provided with blind rivet, the circumferential surface of the other end evenly on four tapering screws are installed, knife bar to be locked in handle of a knife and can the position of fine-adjustable tool bar by tapering screw.
