Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As Figure 1-5, a kind of pin machine binary cycle three cams, comprise: camshaft 2 and string are enclosed within three cams on camshaft, the circumferential shape integral body of three cams is disc, the rotating center of cam is provided with axis hole 12, axis hole 12 inside are provided with pin card 14, and camshaft 2 is provided with a draw-in groove mating with pin card 14, and pin card 14 is fastened in draw-in groove the angle on camshaft 2 and upper-lower position with stationary cam.
Clamp cam 4 is circumferentially with two symmetrical bumps 18, it is the center of circle that basic circle 16 be take the running shaft of clamp cam 4, bump 18 is positioned at basic circle 16 outsides, bump 18 edges are arc, two bump 18 symplex structure settings centered by the running shaft of clamp cam 4, the pin card 14 that clamp cam 4 is provided with can be positioned at any angular position of its axis hole 12 inner sides, and the bump 18 of clamp cam 4 can circumferentially be arranged on camshaft 2 with arbitrarily angled like this.
Push cam 6 and for being provided with circumferential radius, become gradually the disk-shaped structure of large then two periods of change that radius diminishes suddenly, push cam 6 and become gradually large two closed disk-shaped structures of period of change annular that then radius diminishes suddenly for being provided with circumferential radius, push any angular position that pin card 14 that cam 6 is provided with can be positioned at its axis hole 12 inner sides, the bump 20 that pushes like this cam 6 can circumferentially be arranged on camshaft 2 with arbitrarily angled.
Shear cam 8 and be provided with two sections all with the disk-shaped structure of several protuberances 20 for circumferentially symmetrical, shearing cam 8 is circumferentially with two sections of disk-shaped structures that are provided with intensive several protuberances 20 of evenly arranging, the outward edge of protuberance is arcuate structure, the pin card 14 that shearing cam 8 is provided with can be positioned at any angular position of its axis hole 12 inner sides, and the reentrant part 22 of shearing like this cam 8 can circumferentially be arranged on camshaft 2 with arbitrarily angled.
Clamp cam 4 is provided with two bumps 18 that are circumferentially mutually 180 degree angles, push cam 6 and be provided with two radiuses that are circumferentially mutually 180 degree angles closure edge line that the first place that changes joins that gradually pauses, shear cam 8 for be provided with two sections be circumferentially mutually 180 degree angles and with the disk-shaped structure that is provided with intensive several protuberances 20 of evenly arranging, above-mentioned like this three kinds of cams all can be realized cam and rotate a circle, control function and realize two cycles variations, because clamp cam 4, when pushing cam 6 and shearing the casting that cam 8 is provided with, pin card 14 angles can arrange arbitrarily, between three cams are mutual, circumferential angle can arrange arbitrarily, the convenient angle of swing of adjusting between cam is poor, be that rotational time is poor.
The present invention in use, Fig. 1 (a) is the non-protruding portion that cam lever 22 is positioned at clamp cam 4, Fig. 1 (b) is positioned at for cam lever 22 bump 18 that pushes cam 6, when clamp cam 4 is rotated along its rotating center, cam lever 22 relatively rotates along its edge, between bump 18 and non-protruding portion, conversion realizes cam lever 22 and moves, and has so just realized the function that clamp cam 4 control pin machines push mechanism, and pushing mechanism is that the action that the pin band of pin machine is pushed and inserted in device realizes mechanism; Fig. 2 (a) is positioned at for cam lever 22 the edge line radius larger part that pushes cam 6, Fig. 2 (b) pushes cam 6 edge line radius smaller parts for cam lever 22 is positioned at, while pushing cam 6 along its rotating center rotation, cam lever 22 relatively rotates along its edge, between edge line slowly changes gradually and changes suddenly, conversion realizes cam lever 22 and moves, so just realized and pushed the function that cam 6 control pin machines push mechanism, pushing mechanism is that the action that the pin band of pin machine is pushed and inserted in device realizes mechanism; Fig. 3 (a) for cam lever 22 is positioned at, shear cam 8 non-salient point place, Fig. 3 (b) shears cam 8 salient point places for cam lever 22 is positioned at, while shearing cam 8 along its rotating center rotation, cam lever 22 relatively rotates along its edge, at cam edge line relief fabric up conversion, realizing cam lever 22 moves, so just realized and sheared the function that cam 8 is controlled pin machine cutting mechanisms, cutting mechanism is that the action that pin band is cut into the segment length of fixed length realizes mechanism.The every rotation half cycle of cam lever 2, the protuberance 20 of shearing in the segment length on cam 8 just can be realized the repeatedly shear action of cutting mechanism to pin band.
Be disposed on clamp cam 4 on camshaft 2, push cam 6 and shear cam 8 simultaneously by camshaft 2 driven rotary, three cams are controlled clamping device on pin machine simultaneously, are pushed mechanism and cutting mechanism rotation, highly intensive realization being synchronized with the movement of mechanism of three motions on pin machine, avoided the substandard products that produce because of three mechanism kinematic disunities.
Clamp cam 4, the edge line that pushes cam 6 and shear cam 8 are that arc guaranteed can be more steady when cam lever 22 upper blocks move along cam edge line.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine technical scope according to claim scope.
