At present existing automatic circular cutter holder mechanism parts are too much, and the tool holder system complex structure is produced circular cutter holder cost height.A kind of automatic circular cutter holder is disclosed in Chinese patent CN201316811Y and CN102825271A, all exist and rely on the DIP pin when realizing the knife rest revolution, rely on alignment pin during the knife rest location, and two pins are in same pin-and-hole, this is the inevitable two pins motion conditions simultaneously that exists just, and patent CN201316811Y and CN102825271A too much rely on pin when realizing the circular cutter holder function.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, and a kind of mechanism for automatic circular cutter holder function realization is provided, and makes the simple in structure of automatic circular cutter holder, and Installation and Debugging are convenient, and reliability improves.
Technical solution of the present invention is: this mechanism comprises lower knife body, upper knife body, top nut, coarse positioning pin, worm-wheel shaft.One end-toothed disc 1 is arranged at lower knife body top, and the lower knife body side is evenly equipped with the pin-and-hole that cooperates with the coarse positioning pin, and lower knife body has axially and the sliding bearing of radial location function inner the composition with the worm-wheel shaft shaft shoulder; The angled teeth of one circumference are arranged at the upper knife body top, and upper knife body and worm-wheel shaft have an end-toothed disc 2 that matches with end-toothed disc 1 by being threaded in the upper knife body, and the upper knife body lower inside has the groove that cooperates with the coarse positioning pin; The teeth that top nut one end has a circumference to cooperate with the upper knife body teeth; The coarse positioning pin is positioned at the lower knife body pin-and-hole, between coarse positioning pin and the lower knife body spring is arranged.
Further, described worm-wheel shaft one end is connected by key with worm gear, and an end has screw thread.
Further, described top nut and worm-wheel shaft be by being threaded, and pass through nut anti-looseness.
After adopting technique scheme, automatic circular cutter holder structure is become simply, Installation and Debugging are convenient, the reliability height; The knife rest parts adopt many standard components as far as possible, and all the other parts are not high to requirement on machining accuracy, reduce the knife rest production cost.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of mechanism for automatic circular cutter holder function realization comprises lower knife body (1), upper knife body (4), top nut (5), coarse positioning pin (9), worm-wheel shaft (7).One end-toothed disc 1(2 is arranged at lower knife body (1) top), lower knife body (1) side is evenly equipped with the pin-and-hole that cooperates with coarse positioning pin (9), and lower knife body (1) has axially and the sliding bearing of radial location function inner the composition with worm-wheel shaft (7) shaft shoulder; The angled teeth of one circumference are arranged at upper knife body (4) top, upper knife body (4) and worm-wheel shaft (7) are by being threaded, have in the upper knife body (4) one with end-toothed disc 1(2) the end-toothed disc 2(3 that matches), upper knife body (4) lower inside has the groove that cooperates with coarse positioning pin (9); The teeth that top nut (5) one ends have a circumference to cooperate with upper knife body (4) teeth; Coarse positioning pin (9) is positioned at lower knife body (1) pin-and-hole, between coarse positioning pin (9) and the lower knife body (1) spring (8) is arranged.
Upper knife body (4) lower inside has the groove that cooperates with coarse positioning pin (9), as shown in Figure 2.Upper knife body (4) turns clockwise as arrow 1 when needs tool changing position, and coarse positioning pin (9) skids off groove along face 1, and coarse positioning pin (9) does not influence upper knife body (4) rotation; When upper knife body (4) lower knife body (1) needed to clamp, when namely upper knife body (4) was rotated counterclockwise trend just like arrow 2, coarse positioning pin (9) can stop by quilt cover 2, makes upper knife body (4) to descend, and realized clamping.
Upper knife body (4) top teeth and top nut (5) teeth shape and position relation are shown in Fig. 3 ~ 6.As shown in Figure 3, before upper knife body (4) lifted, two teeth tops less than two end-toothed disc raising heights, made upper knife body (4) lift in the process when two end-toothed discs do not separate fully apart from d, and two teeth namely mesh, as Fig. 4; Because two teeth are angled, when two end-toothed discs separated fully, two teeth faces 3 meshed fully, as Fig. 5; When upper knife body (4) lower knife body (1) clamped, because two teeth faces 4 are an inclined-plane, two teeth can be separated into state shown in Figure 6.
Operation principle of the present invention is as follows:
When knife rest need lift tool changing, driving makes worm gear (10) drive worm-wheel shaft (7) rotation, and upper knife body (4) is connected by worm drive with worm-wheel shaft (7), because end-toothed disc 1(2) and end-toothed disc 2(3) engagement, make upper knife body (4) not rotate, upper knife body (4) will upwards lift.When end-toothed disc is thrown off, mesh fully with upper knife body (4) with the top nut (5) that worm-wheel shaft (7) is fixing, upper knife body (4) revolution, the orientation number that it turns over is by the tool changing signal controlling.When arriving required cutter spacing, drive and make worm-wheel shaft (7) backward rotation, upper knife body (4) descends under the effect of coarse positioning pin (9), carries out precision positioning by end-toothed disc during clamping.
Above-described instantiation; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; for those skilled in the art; principle of the invention situation is following not breaking away from; can also make some improvement and distortion, these improvement and the distortion of above-mentioned hypothesis also should be considered as protection domain of the present invention.
