Abstract

The utility model relates to a spring clamp head cutter handle with a driving speed-increasing device, which mainly solves the problem of the speed increase of the cutters on the existing digital controlled machine tools or the machining centers. One end of a low-speed shaft of a cutter handle is provided with a notch; the position of a shaft center of the notch is provided with a sun shaft; the sun shaft is connected with a spring clamp head; a pin body which is connected with the low-speed shaft is also arranged in the notch; a planetary wheel which can drive the sun shaft to rotate is sheathed outside the pin body; a fixing wheel is arranged outside the planetary wheel.

Description

Have the spring chuck handle of a knife that drives speeder

The utility model relates to and has the spring chuck handle of a knife that drives speeder.

At present, no speedup handle of a knife makes grinding in existing Digit Control Machine Tool or Tool Magazine in Machining Centers, especially in hole mill processing difficulties.

The purpose of this utility model is to provide a kind of atwirl spring chuck handle of a knife that drives speeder that has of cutter that can make.

The technical solution of the utility model: a kind ofly have a spring chuck handle of a knife that drives speeder by what spring chuck, handle of a knife etc. constituted, the shaft core position that one end of the slow-speed shaft of handle of a knife has the breach breach is equipped with solar shaft, the sun spring chuck that is coupling, also be equipped with the shank that joins with slow-speed shaft in the breach, shank is with outward and can drives the planetary gear that solar shaft rotates, and planetary gear is equipped with fast pulley outward.

Advantage of the present utility model: compare with existing speed increasing mechanism, gearratio is bigger, and compact conformation operates steadily, and noise is little, the efficient height.Utilize existing Digit Control Machine Tool to realize the cutter speedup, at present domestic still do not have.

Narrate embodiment of the present utility model in conjunction with the accompanying drawings.

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

Fig. 2 is the utility model A-A profile.

One end of the slow-speed shaft 1 of handle of a knife has breach 7, the shaft core position of breach is equipped with solar shaft 5, and solar shaft 5 joins with spring chuck 6, also is equipped with the shank 3 that joins with slow-speed shaft in the breach, shank 3 outer being with can drive the planetary gear 4 that solar shaft rotates, and planetary gear is equipped with fast pulley 2 outward.

During enforcement, shank can be 3～6, and correspondingly the planetary gear that rotates of the driven solar shaft that is with outward of shank can be 3～6, and present embodiment adopts 4 shanks, correspondingly adopts 4 planetary gears.

During work, the moment of torsion of main shaft passes on the slow-speed shaft 1, shank 3 on the slow-speed shaft 1 rotates thereupon, be enclosed within the outer planetary gear 4 of shank also rotates thereupon, solar shaft 5 is driven by 4 planetary gears 4 like this, thereby reaches the purpose that the solar shaft rotating speed is increased, and can rotate at a high speed with the spring chuck 6 that solar shaft joins like this, make cutter can finish the processing of various needs, especially grinding.

Claims

1, a kind ofly has a spring chuck handle of a knife that drives speeder by what spring chuck, handle of a knife etc. constituted, it is characterized in that: an end of the slow-speed shaft of handle of a knife has breach, the shaft core position of breach is equipped with solar shaft, the sun spring chuck that is coupling, also be equipped with the shank that joins with slow-speed shaft in the breach, shank is with outward and can drives the planetary gear that solar shaft rotates, and planetary gear is equipped with fast pulley outward.

2, the spring chuck handle of a knife that drives speeder that has according to claim 1, it is characterized in that: shank can be 3～6, correspondingly the planetary gear that rotates of the driven solar shaft that is with outward of shank can be 3～6.
