In handle of a knife system, handle of a knife is relatively low for usual service life in high precision, and the scope of application of high accuracy handle of a knife is smaller, majority is only applicable to polish, and is not easy to safeguard, during production practices, often encountering because cutter holding shank diameter is excessive cannot deep hole processing or the problem of deep bottom surface, handle of a knife on existing market typically uses worm-and-wheel gear, expensive and interchangeability is very poor, and usual handle of a knife needs to change the type of worm gear when clamping the cutter of different length；And when carrying out the locking of cutter or unclamping operation, manual operation is relatively elaborate；Using the handle of a knife of worm-and-wheel gear, operationally easily there is locking phenomenon in worm gear simultaneously, is unsuitable for the High-speed machining of workpiece.
Summary of the invention
The purpose of this utility model is to provide a kind of moment of torsion handle of a knife tube clamp locking device for the deficiencies in the prior art, lengthening assembly it is provided with in toolholder body, interchangeability is strong, and collet chuck can be solved well when locking or unclamping operation, the defect of time-consuming effort, the problem simultaneously also solving worm gear operationally easily locking, adds the service life of handle of a knife.
The technical scheme in the invention for solving the technical problem is: a kind of moment of torsion handle of a knife tube clamp locking device, including toolholder body, collet chuck and worm-and-wheel gear, central shaft hole it is provided with in toolholder body, described collet chuck is equipped with in the conical cavity of central shaft hole front end, worm gear in worm-and-wheel gear is arranged at the middle part of central shaft hole, and with toolholder body coaxial line install, threaded between worm gear with collet chuck one lengthen assembly；Described lengthening assembly is a body, the outer wall of body is provided with screw thread, and outer wall thread cross section, body front end is rectangular thread or trapezoidal thread, and threadeds with the guiding inner round wall of collet chuck, outer wall thread cross section, body rear end is triangle thread or saw-tooth thread, and is connected with worm gear.
Respectively it is shaped with at the two ends of worm gear one around the annular groove of its outer wall circumferencial direction, in described annular groove, is provided with the one group of steel ball matched with toolholder body inwall.
Being additionally provided with water stop gel ring in described central shaft hole, described water stop gel ring is fixed on the rear end of worm gear outer wall.
The beneficial effects of the utility model are: this utility model by worm-and-wheel gear with realize locking or loosening cutter, laborsaving and change and easy to adjust；Lengthening assembly it is provided with in toolholder body, on the one hand the effective length of handle of a knife can be made to increase, reduce the replacing type of worm gear, on the other hand radially screwing force can be made to be converted into axial tightening power exponentially, it is time saving and energy saving to operate, simple and compact for structure, low cost, the application of described steel ball can make collet chuck only by axial tightening force, is conducive to improving the service life of collet chuck；There is certain pretightning force simultaneously between toolholder body and steel ball, make whole assembling close structure, gapless；Making handle of a knife be more suitable for High-speed machining, dynamic balance is good, and solves the problem of worm gear operationally easily locking, adds the service life of handle of a knife.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.In figure:
1, worm gear, 2. water stop gel ring, 3. collet chuck, 4. lengthen assembly, 5. screw thread, 6. toolholder body, 7. worm screw, 8. steel ball.
Detailed description of the invention
The technical solution of the utility model is further illustrated below by specific embodiment.
As shown in Figure 1: a kind of moment of torsion handle of a knife tube clamp locking device, including toolholder body 6, collet chuck 3 and worm-and-wheel gear, it is provided with central shaft hole in toolholder body 6, described collet chuck 3 is equipped with in the conical cavity of central shaft hole front end, worm gear 1 in worm-and-wheel gear is arranged at the middle part of central shaft hole, and with toolholder body 6 coaxial line install, threaded between worm gear 1 with collet chuck 3 one lengthen assembly 4；Described lengthening assembly 4 is a body, the outer wall of body is provided with screw thread 5, and outer wall thread 5 cross section, body front end is rectangular thread or trapezoidal thread, and threadeds with the guiding inner round wall of collet chuck 3, outer wall thread 5 cross section, body rear end is triangle thread or saw-tooth thread, and is connected with worm gear 1；
One respectively it is shaped with around the annular groove of its outer wall circumferencial direction at the two ends of worm gear 1, the one group of steel ball 8 matched with toolholder body 6 inwall it is provided with in described annular groove, the application of described steel ball 8 can make collet chuck 3 by axial tightening force, is conducive to improving the service life of collet chuck 3；On the other hand use steel ball 8 that the frictional resistance between worm gear 1 and toolholder body 6 inwall can also be made to reduce, be more easy to during rotary worm 7 start, prevent worm gear 1 locking, and then add the service life of handle of a knife；Simultaneously because steel ball 8 has elasticity, the gap between toolholder body 6 and steel ball 8 can be done little during assembling handle of a knife, this allows for there is pretightning force between toolholder body and steel ball 8, makes whole assembling close structure, gapless.Making handle of a knife be more suitable for High-speed machining, dynamic balance is good.
Being additionally provided with water stop gel ring 2 in described central shaft hole, described water stop gel ring 2 is fixed on the rear end of worm gear 1 outer wall, and described water stop gel ring 2 can effectively prevent the coolant of machine tool chief axis from entering worm-and-wheel gear, makes worm and gear be unlikely to oxidation and rusting.
Moment of torsion handle of a knife of the present utility model uses worm-and-wheel gear, during work, with spanner rotary worm 7, worm gear 1 in central shaft hole can rotate accordingly, thus drive collet chuck 3 to move along the axis direction of toolholder body 6, reach locking or unclamp the purpose of collet chuck 3, on the one hand the application lengthening assembly 4 can make the effective length of handle of a knife lengthen, effectively reduce the replacing type of worm gear 1, it is suitable for the production of batch, working (machining) efficiency is high, on the other hand, the outer wall front end of described lengthening assembly 4 is provided with rectangular thread, rear end is provided with the regular screw threads being connected with worm gear 1, during work, radially screwing force can be converted into axial tightening power exponentially, realize the accurate clamping of cutter, during operation, time saving and energy saving；This utility model has the mechanical structure of powerful chucking power and high rigidity；Handle of a knife is made to be applicable to various coarse-fine processing, the beneficially popularization and application of enterprise.
The application of described steel ball 8 can make collet chuck 3 by axial tightening force, is conducive to improving the service life of collet chuck 3；There is certain pretightning force simultaneously between toolholder body 6 and steel ball 8, make whole assembling close structure, gapless；Making handle of a knife be more suitable for High-speed machining, dynamic balance is good, and solves the problem of worm gear 1 operationally easily locking, adds the service life of handle of a knife.
Outside technical characteristic described in description, it is those skilled in the art known technology.
