Abstract
The utility model discloses an overhead active type cam opening device which can weave simple forging and twill weave and can be matched with various types of water jet looms. A cam box arranged on a cam box bracket has the advantages of compact structure, small occupation space, reasonable and scientific layout, easy operation, and convenient installation and maintenance. The cam box has a blocked style, and the elements in a box body are lubricated in an oil bath mode so as to ensure the service life of the device. A conjugate cam of high accuracy controls harness frames to move precisely according to the given characteristics of motion through connecting parts. Therefore, under the high-speed running state of a loom, the harness frames can move up and down smoothly and steadily.
Description
Technical field
The utility model relates to a kind of cam opening device of water jet looms, and especially, the weaving that relates to a kind of suitable various model water jet loomss is simply forged, the overhead cam opening device of twill-weave.
Background technology
Weave the water jet looms that industry uses opening modes such as crank connecting link opening, dobby shedding and cam shedding are arranged, at present domestic is dobby shedding and two kinds of forms of crank connecting link opening substantially, cam shedding is used on a small quantity, and underneath type and middle cam opening device that existing water jet looms is used, complex structure, take up room big, cam box is positioned at the below of harness frame in aweaving machine or is parallel to heald frame height because of the position, water inlet influences the loom operate as normal easily, the operating space is limited simultaneously, inconvenient operation greatly reduces operating efficiency.And existing overhead cam opening device layout is unreasonable, and volume is bigger.
Summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of can be for the weaving of various model water jet loomss configurations is simply forged, the overhead cam opening device of twill-weave.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of overhead cam opening device, upper frame is installed on base tail side and the base member case side by support and cam box support, expansion tightening wheel is installed on the cam box support, cam box is arranged on the cam box support, short connecting rod, handle is connected with cam box with synchronous pulley, connecting plate and shedding arm are installed on the upper frame by axle bed, connecting plate one end links to each other with short connecting rod, the other end links to each other with the heald frame connecting rod with long connecting rod, shedding arm one end links to each other with long connecting rod, and the other end links to each other with the heald frame connecting rod.
Further, described cam box comprises a cam box; Pressing plate, small bevel gear, big bevel gear shaft, camshaft and control lever shaft are installed in the described cam box; Pinion and gamp tooth are installed on the big bevel gear shaft, and gear wheel and cam bit are installed on the camshaft; Control lever shaft one end stretches out outside the cam box, links to each other with described handle; The cam arm axle links to each other with control lever shaft with the control lever shaft connecting rod by cam arm axle push rod; Ring washer, cam arm and plate washer are installed on the cam arm axle successively; Small bevel gear links to each other with described synchronous pulley, and cam arm links to each other with described short connecting rod.
The beneficial effects of the utility model are: cam box is arranged on the cam box support, compact conformation, take up room little, rationally distributed science, simple to operate, installation and maintenance are convenient; Cam box is closed, and the box house part is the oil bath self-lubricating, thereby guarantees the service life of this device; The high accuracy conjugate cam accurately moves by the given characteristics of motion by each attaching parts control heald frame, and under loom ran up state, heald frame moved up and down steadily reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cam box cutaway view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 shows structure of the present utility model, and overhead cam opening device structure of the present utility model mainly is made up of cam box part and shedding opening portion.
Upper frame 3 is installed on base tail side 1 and the base member case side 15 by support 2 and cam box support 14, and base tail side 1 is connected with loom board (not shown) with base member case side 15.Cam box 11 is placed on the cam box support 14.Short connecting rod 9, handle 10 and synchronous pulley 12 are connected with cam box 11, connecting plate 8 is installed on the upper frame 3 by axle bed 6, one end links to each other with short connecting rod 9, the other end links to each other with heald frame connecting rod 4 with long connecting rod 7 respectively, shedding arm 5 is installed on the upper frame 3 by axle bed 6, one end links to each other with long connecting rod 7, and the other end links to each other with heald frame connecting rod 4.Expansion tightening wheel 13 is installed on the cam box support 14, and the harness frame in aweaving machine (not shown) is connected with this device by heald frame connecting rod 4.
During work, motor speed is in synchronous pulley 12 is delivered to cam box 11, cam box 11 drives connecting plate 8 motions by short connecting rod 9, connecting plate 8 directly makes a heald frame connecting rod 4 move up and down on the one hand, driving shedding arm 5 by long connecting rod 7 on the other hand rotates, another heald frame connecting rod 4 is moved up and down, thereby make harness frame in aweaving machine work.
Fig. 2 shows the internal structure of cam box of the present utility model, cam box 22 is a closed shell, pressing plate 26, small bevel gear 16, big bevel gear shaft 18, camshaft 19 and control lever shaft 24 are installed in the cam box 22, pinion 31 and gamp tooth 17 are installed on the big bevel gear shaft 18, gear wheel 30 and cam bit 29 are installed on the camshaft 19, control lever shaft 24 1 ends stretch out outside the cam box 22, link to each other with handle 10.Cam arm axle 20 links to each other with control lever shaft 24 with control lever shaft connecting rod 23 by cam arm axle push rod 21, and ring washer 28, cam arm 25 are installed on the cam arm axle 20 successively with plate washer 27.Small bevel gear 16 links to each other with described synchronous pulley 12, and cam arm 25 links to each other with described short connecting rod 9.
During work, motor speed is after synchronous pulley 12 is delivered to cam box 11, the cam bit 29 that is installed on the camshaft 19 through small bevel gear 16, gamp tooth 17 and pinion 31, gear wheel 30 transmissions in the cam box 11 turns round, cam bit 29 rollers on-stream and on the cam arm 25 contact, the curve law swing that cam arm 25 is set by cam bit 29, short connecting rod 9 links to each other with cam arm 25, motion under cam arm 25 drives.20 motions of pressing plate 26 restriction cam arm axles, ring washer 28 is used to prevent cam arm 25 axial floats with plate washer 27.
Because cam bit 29 be the high accuracy conjugate cam, on-stream, cam bit 29 contacts with cam arm 25 rollers along the limit and is in no gap state basically, so heald frame moves according to the upper and lower opening that the curve law of cam setting carries out active type all the time.
By moving of handle 10, make control lever shaft 24 drive control lever shaft connecting rod 23 and rotate, through cam arm axle push rod 21, make cam arm axle 20 parallel moving, thereby reach the joggleword or the flat purpose of combining of its disengagement of cam arm 25 and cam bit 29.
When changing fabric tissue, must make up by exchange cam, change gear wheel 30, pinion 31 according to the speed ratio needs simultaneously.
The foregoing description is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
