Abstract
The utility model discloses a novel expansion shaft, which comprises a shaft sleeve, an expansion block and an expansion mechanism. The expansion mechanism comprises a mandrel slidably connected with the shaft sleeve, one end of the mandrel is provided with a spring mount, the spring mount is in pressing connection with the shaft sleeve via a spring sleeved on the mandrel, the other end of the mandrel is in screw joint with an adjusting nut which is in crimping fitting with the shaft sleeve, the surface of the mandrel is provided with a sliding groove which is in wedge shape in the direction from the spring mount to the adjusting nut, the shaft sleeve is provided with a sliding hole corresponding to the sliding groove, and the expansion block penetrates the sliding hole to be in sliding connection with the sliding groove. The utility model has simple structure, easy operation and low cost, can be directly inserted into a drum without space occupation, and is easy to be promoted and applied.
Description
Technical field
The utility model relates to a kind of main axis of dilatation, especially adapted novel main axis of dilatation on paper making equipment and paper processing equipment of fixing various flexible packaging cylinder materials.
Background technology
At present, the main axis of dilatation that is used on paper making equipment and the paper processing equipment mainly is made up of axle sleeve, flexible piece, telescoping mechanism, flexible piece is installed in the installation slotted eye of axle sleeve and can be along slotted eye to outer lug or inwardly withdrawal, the telescoping mechanism part mainly is to utilize the expansion of air bag to make flexible piece projection, dead block.But the use of this gas main axis of dilatation need be equipped with air feed equipment and gas path pipe and control convenience and electric power system, complex structure, complex operation, take up space big, cost is high, and often occurs taking place because of air pressure deficiency or gas leakage, sealing member are impaired etc. loosening phenomenon during operation midway.
The utility model content
The utility model provides a kind of novel main axis of dilatation simple in structure, easy to operate, with low cost in order to solve weak point of the prior art.
For solving the problems of the technologies described above, novel main axis of dilatation of the present utility model, comprise axle sleeve, flexible piece and telescoping mechanism, described telescoping mechanism comprises the mandrel with the axle sleeve sliding block joint, mandrel one end is provided with spring perch, be connected by the spring pushing that is set on the mandrel between spring perch and the axle sleeve, the mandrel other end is bolted with the setting nut with the axle sleeve press fit, the mandrel surface is provided with chute, chute is wedge shape at spring perch to the direction of setting nut, axle sleeve is provided with and the cooresponding slide opening of chute, flexible piece be located in the slide opening and with the chute sliding block joint.
Described mandrel is a ferrous materials, and flexible piece inside is provided with magnet.
Adopt said structure, by the rotation setting nut axle sleeve is slided along mandrel, sliding sleeve promotes flexible piece and moves in chute, since chute spring perch to the direction of setting nut to the centroclinal extension setting of mandrel, in the extended or indentation axle sleeve of flexible piece, when flexible piece stretches out, play the effect of expansion; Mandrel is a ferrous materials, is provided with magnet in the flexible piece, and flexible piece is adsorbed in the chute, prevents that flexible piece from coming off; The utility model is simple in structure, easy and simple to handle, with low cost, can directly be located in the reel to use, and does not take up space, and is easy to apply.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, novel main axis of dilatation of the present utility model, comprise axle sleeve 1, flexible piece 2 and telescoping mechanism, telescoping mechanism comprises the mandrel 3 with axle sleeve 1 sliding block joint, mandrel 3 one ends are provided with spring perch 4, be connected by spring 5 pushings that are set on the mandrel 3 between spring perch 4 and the axle sleeve 1, mandrel 3 other ends are bolted with the setting nut 6 with axle sleeve 1 press fit, mandrel 3 is provided with chute 7, chute 7 spring perch 4 to the direction of setting nut 6 to mandrel 3 centroclinal extension settings, form wedge shape, axle sleeve 1 is provided with and chute 7 cooresponding slide openings 8, flexible piece 2 be located in the slide opening 8 and with chute 7 sliding block joints, mandrel 3 adopts ferrous materials, flexible piece 2 inside are provided with magnet 9.On the same section cross-sectional periphery on the mandrel 3 four chutes 7 are set evenly, multistage evenly is set.
During use, the utility model is inserted in the reel rotation setting nut 6, make axle sleeve 1 compression spring 5, axle sleeve 1 promotes to be in the flexible piece 2 in the slide opening 8, and flexible piece 2 slowly outwards expands along chute 7, be fixed as one when flexible piece 2 holds out against the reel inwall, setting nut 6 can stop the rotation.After using end, the utility model can be unloaded, contrarotation setting nut 6, compression spring 5 push collar 1, axle sleeve 1 promotes to be in the flexible piece 2 in the slide opening 8, and flexible piece 2 slowly inwardly shrinks along chute 7, when flexible piece 2 breaks away from the reel inwall, the setting nut 6 that can stop the rotation is extracted the utility model out.Be provided with magnet 9 in the flexible piece 2, flexible piece 2 is adsorbed in the chute 7, prevent that flexible piece 2 comes off and delays work when using the utility model.
Claims (2)
1, novel main axis of dilatation, comprise axle sleeve, flexible piece and telescoping mechanism, it is characterized in that: described telescoping mechanism comprises the mandrel with the axle sleeve sliding block joint, mandrel one end is provided with spring perch, be connected by the spring pushing that is set on the mandrel between spring perch and the axle sleeve, the mandrel other end is bolted with the setting nut with the axle sleeve press fit, the mandrel surface is provided with chute, chute is wedge shape at spring perch to the direction of setting nut, axle sleeve is provided with and the cooresponding slide opening of chute, flexible piece be located in the slide opening and with the chute sliding block joint.
