Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 4, an embodiment of the rapidly adjustable inflatable bed knife of the present invention includes a cutter body 1 having an annular structure, both sides of the cutter body are provided with grooves 2 on the surface for matching and cutting, the diameter of the inner annular surface of the cutter body is slightly larger than that of the cutter shaft, so as to ensure that the cutter body can be sleeved, but no larger clearance allowance exists. An annular groove 3 is formed in the inner annular surface of the cutter body, annular limiting grooves 4 are formed in two groove walls of the annular groove, a plurality of pressing pieces 5 are further arranged at the annular groove opening of the annular groove and are sequentially arranged in the circumferential direction, the cross sections of the pressing pieces are concave, limiting wing edges 6 are arranged on the outer surfaces of two side walls of each pressing piece, the limiting wing edges extend into the corresponding limiting grooves, and the pressing pieces and the limiting wing edges are of an integral structure and have deformation capacity; still be provided with annular gasbag 7 in the annular groove, be provided with on the annular gasbag and fill air cock 8, be provided with operation hole 9 on the cutter body that fills the air cock correspondence, fill the air cock and stretch into the downthehole setting of operation, directly operate in the operation hole during filling the gassing, convenient reliable annular gasbag is through filling the gassing and adjusting the pressure of applying to the compact heap surface.

The utility model changes the fixing mode of the prior bed knife, changes the locking mode of four screws into the air bag type inflatable fixing effect, when in use, a plurality of bed knives are sleeved on the cutter shaft 10 in sequence, the concentricity of the cutter body and the cutter shaft is higher, then each bed knife is fixed in position, when in fixation, the position of the bed knife is determined by the aid of an air source, then the inflation and deflation nozzle is inflated directly, the annular air bag is inflated uniformly, the bottom and the groove wall of the annular groove can not be pushed in the process of inflation, therefore, the inflated annular air bag can extrude the movable pressing sheet to move towards the cutter shaft, the movable pressing sheet is contacted with the groove wall of the annular groove at one side of the circle center by the limit wing edge in the moving process, then the pressing sheet is contacted with the surface of the cutter shaft, when the pressing sheet is contacted with the surface of the cutter shaft, the pressing sheet also tightens the tool body on the cutter shaft, the fixing effect of the pressing sheet is improved by the continuous inflation and extrusion, therefore, when the cutter shaft rotates, the bed knife can synchronously act, and the stress of each part of the annular air bag in the expansion process is uniform, so that the effect of integrally and uniformly applying pressure can be realized by one-time inflation, and the concentricity of the bed knife and the cutter shaft is effectively ensured. And the operation is completed by one-time inflation, so that labor and time are saved, stronger professional experience is not needed, and the use difficulty is reduced.

When the adjustable bed knife needs to be moved, only the inflation and deflation nozzles need to be deflated, when the tensioning force of the annular air bag cannot enable the pressing sheet to be tightly pressed on the knife shaft, the knife body can axially move on the knife shaft, after the required position is adjusted, the operation of inflating is repeated again, and the operation is stable, reliable and efficient.

Specifically, the bottom surface of compressing tightly the piece is the arc structure, and the bottom surface and the interior anchor ring of cutter body with the compressing tightly piece set up with one heart, when lieing in the arbor laminating, can laminate completely, guarantee fixed effect. The lateral wall top of compressing tightly the piece is arc limit structure, and compressing tightly the piece and forms through bending with spacing wing limit, and wherein the radian can be rolled after bending and form, has the advantage that preparation cost is low, efficient, the uniformity is good than welding forming.

And compressing tightly piece and spacing wing limit are the elasticity material, and deformability is strong, and it is effectual to reset, improves life.

In one embodiment, a partition convex part is further arranged in the annular limiting groove between every two adjacent pressing pieces, so that each pressing piece is independently partitioned, the pressure is uniform when the cutter shaft is clamped, the eccentric rotation problem is effectively reduced when the cutter shaft rotates, and the service life of the cutter shaft can be prolonged.

In one embodiment, the contact part of the annular air bag and the pressing piece is fixed through glue, and the annular air bag part and the pressing piece part are adhered together in a glue dispensing mode and the like, so that the pressing piece cannot move in the position of the annular groove opening, the pressure is uniform when the cutter shaft is clamped, the eccentric rotation problem is effectively reduced when the cutter shaft rotates, and the service life of the cutter shaft can be prolonged.

In one embodiment, the number of the inflation and deflation nozzles is at least 2, when the positions of the operation holes are not arranged on the same side, the operation positions can be quickly found, the rotation angle is small, and the operation is convenient.

The above embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
