Abstract
The utility model discloses a camshaft assembly of a weaving machine. The camshaft assembly comprises a camshaft, bearings, a bevel gear disc and a plurality of cam plates, wherein the cam plates are fixed on the camshaft; the bevel gear disc is fixedly connected to one end of the camshaft; the camshaft is fixed on a bearing seat in a box body by virtue of bearings; a detachable end cover is fixedly connected to the other end of the camshaft; and the cam plates and the camshaft are positioned by virtue of positioning keys. The camshaft assembly has the beneficial effects that the cam plates are positioned by using the positioning keys so that an angle position relation among the cam plates does not need to be adjusted when the cam plates are replaced to achieve accuracy in positioning, and different tissue weaving requirements can be simply and conveniently met; and the end cover at the end of the camshaft only needs to be detached without need of totally dismounting the camshaft and the cam plates when the cam plates are mounted or replaced, so that the camshaft assembly is easy and convenient to operate.
Description
Technical field
The utility model relates to technical field of textile machine, particularly a kind of cam assembly of loom.
Background technology
In weaving industry, for completing through the interweaving of, weft yarn, opening, wefting insertion must be arranged on loom, beat up, batch and five elemental motions of the warp let-off, each is completed by corresponding mechanism.Wherein shedding mechanism is warp thread to be divided into the mechanism of the two-layer formation shed open in up and down, can be divided into curved bar connecting rod opening, cam shedding, dobby shedding and jacquard weave opening by opening mode several.Cam shedding mechanism is to utilize cam to control lifting and the order thereof of heald frame, generally uses 2-8 page heald frame, is suitable for producing the fabrics such as various plain weaves, twill, satin weave and corduroy, is being widely used in industry at present.
Existing cam shedding mechanism generally comprises casing, power shaft, cam assembly and swing arm unit are installed in casing, the groundwork principle of cam shedding mechanism is the driven by motor power shaft by the outside, power shaft by bevel gear with transmission of power to cam assembly, cam assembly again by rotor with transmission of power to swing arm unit, swing arm unit drives heald frame and moves up and down.
Cam assembly is the pith of loom cam opening mechanism, formed by camshaft and the cam bit that is fixed on camshaft, between cam bit, different angle position relations can be controlled and realize different establishment tissues, so the installation positioning relation of cam bit initial position is to the realization of fabric establishment tissue.Existing cam assembly need to require constantly to change cam bit and adjust angle position relation between cam bit according to different establishment tissue, and troublesome poeration is located inaccurate again; And when changing cam bit, camshaft and cam bit all need to be pulled down just and can be changed, waste time and energy very much.
The utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and provides a kind of accurate positioning, simple to operate, cam bit to change the cam assembly of loom easily.
The technical solution of the utility model is:
A kind of cam assembly of loom, comprise camshaft, bearing, umbrella fluted disc and several cam bits, described cam bit is fixed on camshaft, described umbrella fluted disc is fixedly connected on an end of camshaft, described camshaft is fixed on bearing block in casing by bearing, it is characterized in that: the described camshaft other end also is fixedly connected with detachable end, locates by positioning key between described cam bit and camshaft.
Each cam bit described in the utility model is provided with an installing hole, cam bit is set on camshaft by installing hole, have the cam keyway on described installing hole, have an axial keyway on described camshaft, described cam keyway, keyway and positioning key match.
End cap described in the utility model is fixed on the end face of camshaft by several screws.
The quantity of screw described in the utility model is three.
The beneficial effects of the utility model are:
1, use positioning key that cam bit is positioned, make the angle position relation that need not to adjust between cam bit when changing cam bit, just can accurately locate, simple and conveniently just can satisfy different knit stitches requirements;
2, install or camshaft and cam bit all need not be pulled down when changing cam bit, the end cap that only need pull down the camshaft end gets final product, and is simple to operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described:
as shown in Figure 1, a kind of cam assembly of loom, be mainly used in the casing of loom cam opening mechanism, comprise camshaft 1, bearing 2, umbrella fluted disc 3 and several cam bits 4, each cam bit 4 is provided with installing hole, cam bit 4 is set on camshaft 1 by installing hole, umbrella fluted disc 3 is fixedly connected on an end of camshaft 1 by umbrella tooth positioning sleeve 10, camshaft 1 is fixed on bearing block in casing by bearing 2, camshaft 1 other end also is fixedly connected with detachable end 5, concrete, end cap 5 is fixed on the end face of camshaft 1 by several screws 9, the quantity of screw 9 is three, only need pull down end cap 5 when installation or replacing cam bit 4 gets final product, simple to operation.
Have cam keyway 7 on the installing hole of cam bit 4, have an axial keyway 8 on camshaft 1, position by positioning key 6 between cam bit 4 and camshaft 1, cam keyway 7, keyway 8 and positioning key 6 match, this locate mode has not only been saved the adjustment to angle position relation between cam bit 1, and accurate positioning.
Cam shedding mechanism also comprises power shaft and swing arm unit, power shaft one end is equipped with the bevel gear with 3 engagements of umbrella fluted disc, swing arm unit is provided with the rotor with cam bit 4 Surface Contacts, during the cam shedding mechanism running, outside driven by motor power shaft, power shaft by bevel gear with transmission of power to camshaft 1, make cam bit 4 revolutions on camshaft 1, cam bit 4 again by rotor with transmission of power to swing arm unit, swing arm unit drives heald frame and moves up and down, thereby warp thread is divided into two-layer formation shed open.
Claims (4)
1. the cam assembly of a loom, comprise camshaft, bearing, umbrella fluted disc and several cam bits, described cam bit is fixed on camshaft, described umbrella fluted disc is fixedly connected on an end of camshaft, described camshaft is fixed on bearing block in casing by bearing, it is characterized in that: the described camshaft other end also is fixedly connected with detachable end, locates by positioning key between described cam bit and camshaft.
