Description
Technical field
The utility model relates to a kind of main axis of dilatation, especially adapted of fixing various flexible packaging cylinder materials at paper making equipment, the main axis of dilatation on the paper processing equipment.
Background technology
Mainly form at the main axis of dilatation that uses at present by outer shaft, flexible piece, telescoping mechanism, flexible piece is inserted in the installation slotted eye of outer shaft and can be along outwards projection or toward interior withdrawal of slotted eye is installed, 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, takes up space, strengthens cost, and loosening midway phenomenon can take place because of air pressure deficiency or gas leakage, sealing member are impaired etc.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate, main axis of dilatation that cost is low.
To achieve these goals, technical solution of the present utility model is this: main axis of dilatation is mainly by outer shaft, flexible piece and telescoping mechanism are formed, wherein telescoping mechanism comprises pull bar, setting nut, pull bar is provided with the circular cone inclined-plane, one end of pull bar is provided with the adjusting outside thread, pull bar is located in the outer shaft and the externally threaded end of adjusting that has of pull bar stretches out beyond the end face of outer shaft, can only relatively move along axis between pull bar and the outer shaft, setting nut is enclosed within the adjusting outside thread place of pull bar and against the outer shaft end face, can only sway mutually between setting nut and the outer shaft and can not relatively move along axis, every flexible piece bottom has at least two fulcrums to be positioned near the circular cone inclined-plane on the pull bar.
Because in the above-mentioned technical solution, pull bar is provided with the circular cone inclined-plane, at the drive lower link of setting nut outer shaft axial slip relatively, the correspondingly slippage between the high-end and low side on pull bar circular cone inclined-plane of fulcrum of flexible piece bottom when the pull bar slippage, when the fulcrum of flexible piece bottom is shifted to when high-end from the low side on circular cone inclined-plane, flexible piece to outer lug then main axis of dilatation be in the expansion mode of operation, when the fulcrum of flexible piece bottom when circular cone inclined-plane high-end shifted to low side, the past interior withdrawal of flexible piece then main axis of dilatation is in contraction state, the utility model mainly is the work purpose that realizes main axis of dilatation by pull bar circular cone inclined-plane and cooperating of flexible piece fulcrum, so this main axis of dilatation has simple in structure, easy to operate, the characteristics that cost is low.
Description of drawings
Fig. 1 is in the structural representation of contraction state for main axis of dilatation provided by the utility model.
Fig. 2 is in the structural representation of swelling state for main axis of dilatation provided by the utility model.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the end face structure scheme drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
In each accompanying drawing: 1, outer shaft; 2, flexible piece; 3, pull bar; 4, setting nut; 5, circular cone inclined-plane; 6, regulate outside thread; 7, fulcrum; 8, roller; 9, retracing spring; 10, thrust baring; 11, transition circle cylinder; 12, circular hole.
As Fig. 1, Fig. 2, shown in Figure 3, main axis of dilatation is mainly by outer shaft 1, flexible piece 2 and telescoping mechanism are formed, telescoping mechanism comprises pull bar 3, setting nut 4, pull bar 3 is provided with circular cone inclined-plane 5, one end of pull bar 3 is provided with regulates outside thread 6, pull bar 3 is located in the outer shaft 1 and the end of regulating outside thread 6 that has of pull bar 3 stretches out beyond the end face of outer shaft 1, can only relatively move along axis between pull bar 3 and the outer shaft 1, setting nut 4 is enclosed within adjusting outside thread 6 places of pull bar 3 and against outer shaft 1 end face, can only sway mutually between setting nut 4 and the outer shaft 1 and can not relatively move along axis, every flexible piece 2 bottom have at least two fulcrums 7 to be positioned near the circular cone inclined-plane 5 on the pull bar 3.
When main axis of dilatation is in Fig. 1 state, the fulcrum 7 of flexible piece 2 is positioned at the low side on the circular cone inclined-plane 5 of pull bar 3, at this moment rotate the adjusting outside thread 6 of setting nut 4 by pull bar 3 and make pull bar 3 relative outer shaft 1 slippages to the right, pull bar 3 slippage after expansion axle to the right then is in state shown in Figure 2, the fulcrum 7 of flexible piece 2 is positioned at circular cone inclined-plane 5 high-end of pull bar 3, flexible 2 states that are positioned to outer lug of piece, in the process of pull bar 3 slippage to the right, the fulcrum 7 of flexible piece 2 is progressively raised to high-end from low side by the circular cone inclined-plane 5 of pull bar 3, and flexible 2 of pieces pass the installation slotted eye of outer shaft 1 progressively to outer lug.As to make main axis of dilatation by Fig. 2 state be transformed into Fig. 1 state in like manner reverse operating get final product.
In order to make flexible piece 2 compacter, flexible with cooperating of pull bar 3 and outer shaft 1, as shown in Figure 1 and Figure 2, be provided with roller 8 at fulcrum 7 places of flexible piece 2 bottoms, be respectively equipped with retracing spring 9 between the two ends of flexible piece 2 and outer shaft 1 inwall.
Resistance is littler when setting nut 4 and outer shaft 1 are relatively rotated at work, between setting nut 4 and outer shaft 1 thrust baring 10 is set as shown in Figure 2; In addition the utility model also is provided with a bit of transition circle cylinder 11 at the lowest part on the circular cone inclined-plane 5 of pull bar 3 as shown in Figure 1 and Figure 2, the transition circle that makes when main axis of dilatation is in contraction state the fulcrum 7 of flexible piece 2 can just in time be parked in pull bar 3 is lived face 11 places, seems more stable.
For the setting nut 4 that makes main axis of dilatation can be driven by bigger torsion, as shown in Figure 4, on the outer face of setting nut 4, be provided with four circular holes 12, utilize a special-purpose wrench that matches with this setting nut 4 that enough big torsion can be provided.
