Detailed description of the invention
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, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-5, a kind of pin machine binary cycle three cam, comprise: camshaft 2 and three cams be enclosed within camshaft of going here and there, the circumferential shape entirety of three cams is disc, the pivot of cam is provided with axis hole 12, axis hole 12 inside is provided with pin card 14, and camshaft 2 is provided with a draw-in groove mated with pin card 14, and pin card 14 is fastened in draw-in groove with the angle of stationary cam on camshaft 2 and upper-lower position.
Clamp cam 4 is provided with circumferentially by thin thickening gradually two symmetrical thickness mapped structures, clamp cam 4 circumferential edge is provided with two with the thick point 16 of its rotating shaft center's symmetry and two with the thin point 18 of its rotating shaft center's symmetry, thick point 16 and thin point 18 are respectively thickness maximum point and thickness smallest point in clamp cam 4, the pin card 14 that clamp cam 4 is provided with can be positioned at any angular position inside its axis hole 12, and the thick point 16 of such clamp cam 4 or thin point 18 can be arranged on camshaft 2 with arbitrarily angled in circumference.
Push cam 6 and be circumferentially with two symmetrical protuberances 20, first basic circle 24 is to push the rotating shaft of cam 6 for the center of circle, it is outside that protuberance 20 is positioned at the first basic circle 24, protuberance 20 edge is arc, two protuberances 20 symmetrical structure centered by the rotating shaft pushing cam 6 is arranged, push pin card 14 that cam 6 is provided with and can be positioned at any angular position inside its axis hole 12, the protuberance 20 pushing cam 6 like this can be arranged on camshaft 2 with arbitrarily angled in circumference.
Shearing cam 8 is circumferentially with two symmetrical recess 22, second basic circle 26 is to shear the rotating shaft of cam 8 for the center of circle, it is inner that recess 22 is positioned at the second basic circle 26, recess 22 edge is arc, two recess 22 symmetrical structure centered by the rotating shaft shearing cam 8 is arranged, the pin card 14 that shearing cam 8 is provided with can be positioned at any angular position inside its axis hole 12, and the recess 22 shearing cam 8 like this can be arranged on camshaft 2 with arbitrarily angled in circumference.
Clamp cam 4 is provided with two groups of thick points 16 and thin point 18 and circumference is mutually 180 degree of angles, push cam 6 and be provided with two groups of protuberances 20 and circumference is mutually 180 degree of angles, shearing cam 8 is provided with two groups of recess 22 and circumference is mutually 180 degree of angles, above-mentioned like this three kinds of cams all can realize cam and rotate a circle, controlling functions realizes two mechanical periodicity, because clamp cam 4, when pushing cam 6 and shear casting that cam 8 is provided with, pin card 14 angle can be arranged arbitrarily, between three cams are mutual, the angle of circumference can be arranged arbitrarily, the anglec of rotation between convenient adjustment cam is poor, namely rotational time is poor.
The present invention in use, Fig. 1 (a) is positioned at the thick point 16 of clamp cam 4 for cam lever 28, Fig. 1 (b) is positioned at the thin point 18 of clamp cam 4 for cam lever 28, when clamp cam 4 rotates along its pivot, cam lever 28 relatively rotates along its edge, between thick point 16 and thin point 18, conversion realizes the folding of cam lever 28, so just achieves the function that clamp cam 4 controls pin machine clamping device, and clamping device is that the fixed convenient action of shearing that kept steady by the pin strap clamp of pin machine realizes mechanism; Fig. 2 (a) pushes the non-protruding portion of cam 6 for cam lever 28 is positioned at, Fig. 2 (b) pushes the protuberance 20 of cam 6 for cam lever 28 is positioned at, push cam 6 when rotating along its pivot, cam lever 28 relatively rotates along its edge, between protuberance 20 and non-protruding portion, conversion realizes cam lever 28 and moves, so just achieve and push cam 6 and control the function that pin machine pushes mechanism, push mechanism and the pin band of pin machine to be pushed and action in inserter instrument realizes mechanism; Fig. 3 (a) shears the non-re-entrant portion of cam 8 for cam lever 28 is positioned at, Fig. 3 (b) shears the recess 22 of cam 8 for cam lever 28 is positioned at, when shearing cam 8 rotates along its pivot, cam lever 28 relatively rotates along its edge, between recess 22 and non-re-entrant portion, conversion realizes cam lever 28 and moves, so just achieve and shear the function that cam 8 controls pin machine cutting mechanism, cutting mechanism is that action pin band being cut into the segment length of regular length realizes mechanism.
Be disposed on clamp cam 4 on camshaft 2, push cam 6 and shear cam 8 simultaneously by camshaft 2 driven rotary, three cams control clamping device on pin machine simultaneously, push mechanism and cutting mechanism rotates, highly intensive achieves being synchronized with the movement of the mechanism of three motions on pin machine, avoids the substandard products produced because of three mechanism kinematic disunities.
Fig. 5 (a) and Fig. 5 (b) is respectively the structural representation of clamp cam and shears the perspective view of cam.Can be relatively steady when the arc of recess 22 and protuberance 20 edge line ensure that cam lever 28 upper block moves along cam edge line, the varied in thickness in clamp cam 4 between thick point 16 to thin point 18 is relatively more even also can ensure steady along during camming movement of cam lever 28 upper block.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to right.
