Problems solved by technology
The power part is driven by a planar conjugate cam mechanism, which has a complex structure and high manufacturing precision requirements. The design of the electromagnetic clutch has a circuitous structure and many parts. Within the limited 12 mm distance, the thickness of the most clutch parts is only about 2.5 mm. The main shaft rotates at a high speed. The clutch is carried out in the middle, and the impact force is generated, which makes it difficult to control the heat treatment process of the material, the damage rate of key parts is high, and the service life is limited

Embodiment Construction
[0018] Combined with the accompanying drawings:
[0019] Such as figure 1 As shown, the "electronic cam" swing dobby is mainly composed of frame 1, double-balanced voice coil motor 2, swing main shaft 3, swing mechanism 4, lifting arm assembly 5, lifting clutch lever 6, positioning assembly 7 and other components composition.
[0020] The double-balanced voice coil motor 2 provides the swinging power, so that the swinging main shaft 3 swings regularly; as figure 1 , figure 2 As shown, the present invention selects two completely identical linear motion voice coil motors, and the two voice coil motors are symmetrically installed on both sides of the drive end of the swing main shaft 3; Parts such as voice coil motor coil card holder 2-3, card holder slide block 2-4, card holder connecting rod 2-6 are also identical. Two sets of identical push rod crank mechanisms with reverse movement are formed on both sides of the active swing beam.
[0021] Oscillating on spindle 3, as...

The invention provides an 'electronic cam' oscillating dobby. An ideal movement curve is obtained by adopting the technology of electronics to replace traditional mechanical conjugate cam mechanisms. A power transmission mechanism selects two identical linear voice coil motors which are symmetrically installed on the two sides of an oscillating spindle; an electromagnetic on-off device is formed in such a manner that on-off electromagnets are installed on connecting beams of symmetrical lifting bodies on the two sides of an oscillating mechanism; vertical lifting on-off rods are arranged in the middle of two connecting beams; taper holes are formed on the two sides of the upper parts of the lifting on-off rods and coincide with taper heads at the front ends of moving rods of the on-off electromagnets to achieve on and off; sliding chutes are formed in the middle lower parts of the lifting on-off rods; one ends of connecting sliding rods move in the sliding chutes and the other ends are hinged with lifting knife arms; holes are formed in the lower ends of the lifting knife arms and are in movable fit with lifting knife arm mandrels. The 'electronic cam' oscillating dobby has the advantages that movement of the voice coil motors can be controlled by an electronic circuit and then the lifting knife arms obtain the ideal oscillating rule, and independent operation of each lifting knife arm can be achieved, thus meeting the weaving process requirements of textile machines.
Description
technical field [0001] The invention relates to an electronic dobby that drives the warp heald frame of a textile machine, in particular to an "electronic cam" swing type dobby. Background technique [0002] The electronic dobby is a machine that controls the electromagnetic clutch device by a computer, and then realizes the transmission of the warp heald frame of the textile machine. Compared with mechanical dobbies, it is more convenient to change the movement law of the heald frame, that is, to change the pattern of textile fabrics, shorten the development cycle of new products, and create higher economic benefits. This is the development direction of modern flower-shaped weaving shedding machinery. [0003] There are two main subjects in the design of the electronic dobby: 1. Adopt an ideal power mechanism so that the movement law of the lifting arm that drives the warp heald frame of the textile machine meets the requirements of the weaving process, especially when the ...
