Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

A multistage coil driving apparatus as shown in fig. 1 and 2 includes an inner sleeve 1; the inner sleeve 1 is sleeved with a front mounting plate 2, a driving coil 3 and a rear mounting plate 5 from front to back, wherein the driving coil 3 is a plurality of stacked mounting plates arranged between the front mounting plate 2 and the rear mounting plate 5.

And a shock absorption pad 4 is arranged between the driving coil 3 and the rear mounting plate 5.

The driving coil 3 is composed of a left baffle 7 and a right baffle 13, the left baffle 7 and the right baffle 13 are parallel to each other, and a sleeve 8 is fixed between the left baffle 7 and the right baffle 13 at the position of an inner ring.

A cable installation bottom plate 11 is arranged on the right baffle 13, a coil 12 is wound on the sleeve 8 and limited by the left baffle 7 and the right baffle 13, and the cable installation bottom plate 11 is connected with the coil 12 in a wiring mode.

A bushing 10 is arranged between the left baffle 7 and the right baffle 13, and the central axis of the bushing 10 is perpendicular to the plane where the left baffle 7 and the right baffle 13 are located.

The bushing 10 is fixed by a threaded sleeve 9 on the left baffle 7 and the right baffle 13.

The bushing 10 forms a straight passage in the plurality of stacked drive coils 3 through which a screw rod passes.

The screw rods are fastened through the tension bolts 6 at the two ends, and the tension bolts 6 are located on the front end face of the front mounting plate 2 and the rear end face of the rear mounting plate 5.

The front mounting plate 2 and the rear mounting plate 5 are formed by symmetrically mounting two semicircular rings.

Generally, the number of the driving coils 3 is five or more.

Thus, the inner sleeve guides the movement of the armature and is also the axial center of the drive coils of each stage when mounted. The front and rear mounting plates are made of steel plates, and a semi-ring structure is adopted to reduce eddy current loss of the electromagnetic coil. The shock pad has certain shock attenuation effect. The tension bolt is used for fixing each stage of coils when the multi-stage coil driving device is assembled, so that the modularization of the driving device is realized.

When the device is used, the load is driven by utilizing the electromagnetic force, and the object throwing acceleration control can be realized by adjusting the number of turns of each stage of driving coil or adjusting the current passing through the coil. The speed of projecting the object is maximized by the gradual acceleration of the multi-stage driving coils.
