The specific embodiment
Referring to Fig. 1-3, cam box 27 is installed on the upper right support 25 of right wallboard 22 of loom and bottom right support 24 tops, the shedding assembly is installed on the shedding axle bed (not drawing among the figure) that is fixed on the forward and backward side channel steel 18,17, through synchronous pulley 2 synchronous pulley 3 on the cam box is passed in motion with the synchronous pulley 1 that loom main shaft connects firmly together, through bevel gear pay 4 and 5 and roller gear pay 28 and 29 camshaft 6 rotated counterclockwise.Be fixed on the camshaft 6 each to conjugate cam 7 and two cam followers, the 8 mutual applying transmissions that are installed in the swing arm 9, and make swing arm 9 reciprocally swingings.Swing arm 9 is by shedding connecting rod 10 and slide over connector 11 on the main shedding arm 12 and drive main shedding arm 12 and swing.Connecting rod 13 by mitered makes secondary shedding arm 14 swing synchronously with main shedding arm 12 again.Major and minor shedding arm 12,14 drives two ends montant assembly 15,16 and does upper and lower being synchronized with the movement, and does the upper and lower opening motion thereby further drive heald frame 23.It is 1: 4 or 1: 5 or 1: 6 that the number of teeth of change synchronous pulley 1 can make the camshaft 6 and the rotating ratio of loom main shaft.The right wallboard 22 of loom, bottom right support 24, upper right support 25, cam box 27, Connection Block 34, forward and backward side channel steel 17,18, upper left support 19, lower-left support 20, loom left side wallboard 21 have constituted a sealing braced frame.Connecting rod 13 and major and minor shedding arm 12,14 mitereds, thus two hinges that make heald frame 23 and opening montant assembly 15,16 apart from increase, thereby increased coupling stiffness between heald frame and opening montant, and then increased the upper and lower stability of making harness motion of heald frame.Shedding connecting rod 10 on main shedding arm 12, is adjusted the upper and lower position of connector 11 by connector 11 sliding sleeves, can regulate the size of opening amount, and demonstrates the opening amount by the scale on the main shedding arm 12.Some flange both sides of conjugate cam 7 and gear 29 being fixed in camshaft 6 by N root bolt (N decides on the fabric tissue requirement).Every pair of conjugate cam gross thickness is that 14mm is corresponding with heald frame spacing 14mm.Every pair of conjugate cam is provided with this cam and turns round than corresponding connecting hole, and other is provided with one identifying hole is installed.Some conjugate cam is arranged by the fabric requirement after and the driven gear of roller gear in paying be fixed in the both sides of camshaft upper flange with bolt.Conjugate cam, cam maximum diameter are 111.5mm, and path is 92.5mm, and revolution is than being 1: 4 or 1: 5 or 1: 6.Spacing when camshaft and arm shaft are in the operating position is 182.5mm.Cam box is provided with two protection inner covers, and friction of motion is paid to adopt and bathed oil lubrication or guide oily stream to lubricate by inner cover in the casing, and the casing external friction is paid to adopt and regularly annotated lubricant grease or adopt special sealed bearing to be lubricated.Being provided with of outer protective cover can effectively be prevented the intrusion of sealing and dust etc. and be prevented spilling of the interior lubricating oil of case in the casing.Cam box 27 and upper right support 25 are affixed.Upper right support 25 is can be on bottom right support 24 forward and backward to be moved (upper left support 19 is also done corresponding forward and backward moving) to adapt to the requirement of different water jet looms types to the forward and backward position of heald frame corresponding relation.Fig. 4 has provided a kind of shape of conjugate cam sheet, and Fig. 5 is the cam follower structure chart, and Fig. 8 is the heald frame height adjusting mechanism, and is all identical with disclosed structure, no longer explanation.Fig. 6 is a cam follower from two swing arm structure figure that install respectively, and is this from two designs that cam follower is installed respectively, simplified the structure of swing arm greatly, and processing technology is good.Referring to Fig. 1,2 and Fig. 7, flat comprehensive mechanism is a pair of toggle that is synchronized with the movement, can realize the accurate location of arm shaft, thereby guarantee swing arm and corresponding each conjugation precision to conjugate cam, swing arm and corresponding conjugate cam are thrown off fully, make swing arm be in given unique position, realize that flat the combining of loom operated.When each swing arm is in normal operation position, all be in transmission connection with corresponding shedding connecting rod.Flat heddle handle 26 is enclosed within on the flat heddle shaft 33, and is fixing with screw 42.Crank 32 left ends are inserted in respectively in two holes of flat heddle shaft 33, and (cutting one among the figure), and fix with nut.Crank 32 is hinged with connecting rod body 31, connecting rod body 31 and connecting rod cap 37 are screwed to link assembly and are enclosed within on the arm shaft 30, the flat part of arm shaft two end mills places the elongated slot of forward and backward swing arm support, and the swing arm support is joined together by swing arm stake body 35 and swing arm bracket cover 36 usefulness securing members.Swing arm stake body 35 lower ends and cam box 27 bottom surface boss are affixed.Flat comprehensive operation sequence is as follows: pull flat heddle handle 26 with hand and clockwise rotate, then flat heddle handle 26 drives flat heddle shafts 33 and crank 32 by direction rotation shown in Figure 7, by flat combine connecting rod (31,37) pulling swing arm 30 along the elongated slot of arm swing support (35,36) to left 24mm.Because the gravity of heald frame 23 itself and the tension force effect of warp thread are moved the swing arm lower ends downward, contact with boss in the casing shown in Figure 1, thereby make swing arm be in unique definite position, realize that flat combining operate.Otherwise, flat heddle handle is turned back position shown in Figure 1, and flat heddle handle 26 and upper right support 25 are fixed, then the utility model is in normal operation position.
