Order of the present utility model is, proposes a kind ofly can carry out linkage driving and the foolproof a kind of link gear of knitting cam of structure to three knitting cams, and it is realized by following technical scheme:
Comprise mount pad shift fork and knitting cam, shift fork is hinged on the mount pad, its two ends connect a knitting cam A and knitting cam B respectively, it is characterized in that also comprising cam and motor, be respectively equipped with curved surface cam path and plane cam groove on all sides of described cam and the end face, cam is connected on the output shaft of motor and places the side of knitting cam B, described knitting cam B is plugged on by the pin that is provided with on it in curved surface cam path of cam and is in transmission connection with it, knitting cam C is plugged on by the pin that is provided with on it in plane cam groove of cam and is in transmission connection with it, during cam rotation, promoting knitting cam B respectively by its top-surface camber cam path and plane cam groove moves up and down, knitting cam C move left and right, knitting cam B moves up and down and drives shift fork when pin joint rotates, and knitting cam A is done and reverse the moving up and down of knitting cam B.
Described mount pad is provided with two slotted eyes, is respectively equipped with trundle on described knitting cam A and the knitting cam B, and this trundle is plugged on respectively in the corresponding slotted eye, and when shift fork rotated, knitting cam A and knitting cam B moved along slotted eye.
The trundle of described knitting cam A and knitting cam B is provided with the link slot with its axis normal, and the two ends of shift fork are plugged on respectively in the link slot of knitting cam A and knitting cam B by the slotted eye on the mount pad.
Described pin on the knitting cam B is arranged on the trundle of this knitting cam.
Described knitting cam A, knitting cam B and knitting cam C are respectively transfer cam, lopping back stitching trigonometric sum tuck cam.
Link gear of knitting cam of the present utility model is made up of mount pad, shift fork, cam and four parts of motor substantially, and on all sides of cam and end face, cam path is set respectively, be used for the knitting cam that promotes three different motion directions, produce such beneficial effect thus: the part of forming mechanism is few, structure is very simple, manufacturing cost reduces, and drive line succinctly and according to the movement relation between three knitting cams is united driving, the motion credibility height.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is the structure diagram of cam.
Among the figure, 13 transfer cams, 13a trundle, 13b link slot, 16 tuck cams, 16a pin, 17 lopping back stitching triangles, 17a trundle, 17b link slot, 17c pin, 21 mount pads, 21a, 21b slotted eye, 22 shift forks, 23 cams, 23a curved surface cam path, 23b plane cam groove, 24 motors.
The specific embodiment
Below in conjunction with drawings and Examples the utility model and advantage thereof are described further.
Present embodiment will illustrate the utility model with the knitting cam of the lopping back stitching triangle in the computer flat-bed knitting machine, transfer cam and these three activities of tuck cam.
See also Fig. 1, triangle link gear of the present utility model mainly is made up of mount pad 21, shift fork 22, cam 23 and motor 24.Shift fork 22 is hinged on the mount pad 21, can rotate around pin joint, is respectively equipped with slotted eye 21a, 21b on the mount pad 21 of these pin joint both sides.Be respectively equipped with trundle 13a, 17a on the rear end face of transfer cam 13, lopping back stitching triangle 17, this two trundle is plugged on respectively among slotted eye 21a, the 21b.Be respectively equipped with link slot 13b, 17b with its axis normal on trundle 13a, the 17a, the two ends of shift fork are plugged on respectively among link slot 13b, the 17b of transfer cam 13 and lopping back stitching triangle 17 by slotted eye 21a, 21b on the mount pad.
See also Fig. 2, be respectively equipped with curved surface cam path 23a and plane cam groove 23b on all sides of cam 23 and the end face.Cam 23 is connected on the output shaft of motor 24 and places mount pad 21 1 sides, and the side connecting pin 17c of the trundle 17a on the lopping back stitching triangle 17 is plugged on by this pin 17c and realizes among the curved surface cam path 23a of cam 23 all sides and being in transmission connection of cam.Also be provided with plane cam groove 23b on one end face of cam 23, tuck cam 16 rear sides are connected with key seat, and the pin 16a on the key seat is plugged among the plane cam groove 23b, make tuck cam 16 and cam 23 realize being in transmission connection.
