Abstract
The invention discloses an expansion shaft of a metallic film slitter, and the invention is characterized in that: the invention comprises a cylindrical shaft; the two ends of the cylindrical shaft are sleeved with nuts, expansion rings and antiskid positioning rings in order; the expansion ring is composed of two fixed loops, a rubber ring for connecting the two fixed loops and several expansion ribs sleeved at the outside of the rubber ring; one end of the nut is embedded into the expansion ring, one end of the nut is embedded into the rubber ring, thereby supporting the rubber ring and the expansion ribs sleeved on the rubber ring. The expansion shaft of the structure does not employ air bags and telescoping blocks, so that the structure is simple and the halfway loosening problem due to insufficient air pressure or leakage or sealing member damage or the like disappears.
Description
Technical field
The present invention relates to a kind of main axis of expansion, particularly relate to a kind of main axis of expansion for metallic film cutting machine.
Background technique
Form primarily of outer sleeve, telescopic block, extending means at the main axis of expansion used at present, in the installation slotted eye that telescopic block is inserted in external axle sleeve and can along installation slotted eye outwardly convex or toward interior retraction, extending means part mainly utilizes the expansion of air bag to make telescopic block protruding, dead block.But the use of this main axis of expansion needs configuration air feed equipment and gas path pipe and control apparatus and Mechatronic Systems, takes up space, strengthens cost, and midway can be there is loosen phenomenon because air pressure is not enough or gas leakage, Sealing are impaired etc.
Summary of the invention
The object of the invention is to solve main axis of expansion complex structure, maintenance cost high, take up space large and because air pressure is not enough or gas leakage, Sealing problem midway occurring and loosens such as impaired, provide a kind of main axis of expansion for metallic film cutting machine.
The technical solution used in the present invention is: a kind of main axis of expansion for metallic film cutting machine, comprise cylindrical shaft, described cylindrical shaft two ends are socketed with nut, expanding ring and anti-skidding positioning ring successively, described expanding ring is made up of two pieces of retaining rings, the rubber ring connecting two pieces of retaining rings and the some expansion muscle be socketed in outside rubber ring, described nut one end is goed deep in expanding ring, props up rubber ring and be socketed in the expansion muscle on rubber ring when nut one end is deep into rubber ring.
As a further improvement on the present invention, positioning ring is provided with groove.
Improve further as of the present invention, positioning ring surface is for utilizing the high coefficient of friction layer of process for treating surface direct forming again.
Further improve as of the present invention, positioning ring surface coverage has high coefficient of friction layer.
The beneficial effect that the present invention adopts is: the main axis of expansion of this structure, owing to not using air bag and telescopic block, makes structure simple and there will not be the problem because the generation midways such as air pressure is not enough or leak gas, Sealing is impaired loosen.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is side view of the present invention.
Fig. 3 is nut schematic diagram.
Fig. 4 is expanding ring schematic diagram.
Shown in figure: 1 cylindrical shaft, 2 nuts, 3 retaining rings, 4 rubber rings, 5 expansion muscle, 6 positioning rings.
Embodiment
Below in conjunction with Fig. 1 to Fig. 4, the present invention is described further.
As shown in the figure, a kind of main axis of expansion for metallic film cutting machine, comprise cylindrical shaft 1, cylindrical shaft 1 two ends are socketed with nut 2, expanding ring and anti-skidding positioning ring 6 successively, expanding ring is made up of two pieces of retaining rings 3, the rubber ring 4 connecting two pieces of retaining rings and the some expansion muscle 5 be socketed in outside rubber ring, described nut 2 one end is goed deep in expanding ring, the expansion muscle 5 propped up rubber ring 4 when nut 2 one end is deep into rubber ring and be socketed on rubber ring.
In order to strengthen anti-skidding, the locating function of positioning ring 6, positioning ring 6 is provided with groove.
The surface of positioning ring 6 is for utilizing the high coefficient of friction layer of process for treating surface direct forming.Use the positioning ring after sufacing processing, larger friction factor can be provided.
Also can at positioning ring 6 surface coverage one deck high coefficient of friction layer.
Use the main axis of expansion of this structure, as long as when one end of nut 2 is deep in rubber ring 4 by rotating nut 2, the expansion muscle 5 propped up rubber ring 4 and be socketed on rubber ring 4.Not only simple, convenient use, and structure simple, be easy to safeguard.Simultaneously owing to not using air bag and telescopic block, there will not be the problem because the generation midways such as air pressure is not enough or leak gas, Sealing is impaired loosen.
