Abstract
The utility model relates to a coupling device of a wire storage tube for electro-spark wire-electrode cutting machine tools. A motor rotary shaft [1] of a motor [2] is fixedly connected to a first connection flange [3]; a wire storage tube shaft [7] is fixedly connected to a second connection flange [5]; the axes of the shaft of the motor rotary shaft [1], the first connection flange [3], the wire storage tube shaft [7] and the second connection flange [5] are coincident. The utility model is characterized in that magnetic steel is fixedly arranged on one or both of the first connection flange [3] and the second connection flange [5]; a gap [8] is arranged between the first connection flange [4] and the second connection flange [5]. When directions of the motor are reversed, reversing impact force on the coupling device of the motor disappears because the gap is arranged between the two flanges which are not contacted. The utility model improves the service life and has no noise.
Description
The utility model relates to a kind of shaft coupling, the shaft coupling that particularly a kind of electric spark linear cutting machine is.
In the prior art, the wire storage tube of electric spark linear cutting machine needs just to change at high speed, reverse when work, driving machine shaft that wire storage tube rotates fixes by rotating shaft on shaft coupling and the wire storage tube and connects, its coupling mechanism is that rigid attachment has four cylinder axis on the ring flange, and these four cylinder axis are inserted in four circular holes of another flange.To the impulsive force of shaft coupling, between cylinder axis and circular hole, be provided with the rubber washer of cushioning effect when eliminating forward and backward.This structure in use, the meeting under constantly impacting of elastic tape is decreased meeting and is needed often replacing, owing to the cylinder axis on two flanges and the influence of the machining accuracy between the circular hole, can make the rotation of wire storage tube produce noise and vibrations, influence the machining accuracy of wire electrode.
The purpose of this utility model is to provide the shaft coupling of a kind of noiselessness, stable transmission electric spark linear cutting machine wire storage tube.
The technical solution of the utility model is: a kind of shaft coupling of electric spark linear cutting machine wire storage tube, the machine shaft of motor is fixedly connected on first connecting flange, the wire storage tube axle is fixedly connected on second connecting flange, and the axial line of described machine shaft, first connecting flange, wire storage tube axle, second connecting flange coincides; In described first connecting flange and second connecting flange, have at least on the flange to be fixed with magnet steel, leave the gap between described first connecting flange and described second connecting flange and directly be not connected.When motor rotated, by the extremely strong magnetic on two ring flanges, the feasible flange that is connected with wire storage tube was by magnetic attraction and drive its rotation.
The utility model compared with prior art has following advantage:
(1), when motor commutation do not contact owing to leave the gap between two ring flanges, so the impulsive force of motor commutation just do not existed on shaft coupling, improved service life, do not have noise.
(2), wire storage tube is not subjected to the influence of the connection precision of shaft coupling, so the wire storage tube running is steadily.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is a structural front view of the present utility model; Wherein:
[1], machine shaft; [2], motor; [3], first connecting flange; [4], first magnet steel; [5], second connecting flange; [6], second magnet steel; [7], wire storage tube axle; [8], gap; [9], connecting key; [10], connecting key;
Embodiment: referring to accompanying drawing, a kind of shaft coupling of electric spark linear cutting machine wire storage tube, the machine shaft [1] of motor [2] is fixedly connected on first connecting flange [3], wire storage tube axle [7] is fixedly connected on second connecting flange [5], and the axial line of described machine shaft [1], first connecting flange [3], wire storage tube axle [7], second connecting flange [5] coincides; In described first connecting flange [3] and second connecting flange [5], have at least on the flange and be fixed with magnet steel, leave gap [8] between described first connecting flange [4] and described second connecting flange [5], make between the connecting flange of winning [4] and second connecting flange [5] not contact, make the connecting flange of winning [4] drive second connecting flange [5] by its magnetic attraction and rotate.
Be fixed with first magnet steel [4] on described first connecting flange [3], be fixed with second magnet steel [6] on described second connecting flange [5], leave gap [8] between the opposite face of described first magnet steel [4] and described second magnet steel [6] and polarity opposite, the size in gap [8] is 0.3 micron to 2 millimeters, outside this scope also can, as long as suitably select the magnetic strength of magnet steel.
Claims (2)
1, a kind of shaft coupling of electric spark linear cutting machine wire storage tube, the machine shaft [1] of motor [2] is fixedly connected on first connecting flange [3], wire storage tube axle [7] is fixedly connected on second connecting flange [5], and the axial line of described machine shaft [1], first connecting flange [3], wire storage tube axle [7], second connecting flange [5] coincides; It is characterized in that: in described first connecting flange [3] and second connecting flange [5], have at least on the flange to be fixed with magnet steel, leave gap [8] between described first connecting flange [4] and described second connecting flange [5].
2, the shaft coupling of electric spark linear cutting machine wire storage tube according to claim 1, it is characterized in that: be fixed with first magnet steel [4] on described first connecting flange [3], be fixed with second magnet steel [6] on described second connecting flange [5], leave gap [8] between the opposite face of described first magnet steel [4] and described second magnet steel [6].
