The mechanical expansion shaft has strong expansion ability and high reliability, and especially suitable for being used in vacuum conditions.
Description
Technical field
The utility model relates to a kind of machinery axle that expands, the folding and unfolding spool of associated mechanical such as it is fit to be applied to be coated with, cuts, printing, rewinding, compound, papermaking, plastics.
Background technology
At present, for be coated with, cut, the unwinding and rewinding of the flexible parent metal of industries such as printing, rewinding, compound, papermaking, plastics adopt the mounting means of the axle that expands.Its characteristics are easy to loading and unloading, the production efficiency height.Bloated axle mainly contains air sac and two kinds of structures of mechanical type.Air bag type expanded shaft utilizes airbag aeration to promote protruding key or lath swelling reel.Because the constructional feature of air bag type expanded shaft, because the weight of the axle that expands causes the protruding key of below shorter than the distance that the protruding key of top stretches out, it is bad with the concentricity of reel that the back axle that expands is installed during installation.Protruding key or lath are by the gaseous tension swelling reel in the air bag, no self-lock ability simultaneously.When vacuum condition uses down, also has the big problem of gas leakage in the air bag.The mechanical type axle that expands, for the volume core diameter hour, the methods that adopt volume cores end with centrum locking more.This method has the problem that coupling mechanism force is strong and core is rolled up in damage.Problem is more serious when especially rolling up the core tube and being paper web.
Summary of the invention
The purpose of this utility model is to provide a kind of swelling ability strong, and the reliability height is particluarly suitable for the bloated axle of machinery that uses under the vacuum condition.
Realize the technical scheme of the utility model purpose: the bloated axle of a kind of machinery, it comprises the beam barrel body that expands, be fixed with axle head at bloated beam barrel body front end, penetrate the beam barrel body inside of expanding in the through hole that mandrel has from the simplified other end of axle that expands, and mandrel is fixed on the beam barrel body that expands by clamp sleeve; Be arranged with two swelling centrums in mandrel both sides external, the beam barrel body inside of expanding, each swelling centrum periphery is equipped with 4 bloated pawls that can promote to stretch out bloated beam barrel body.
The bloated axle of aforesaid a kind of machinery, its with each junction, swelling centrum end, the beam barrel body that expands on be equipped with groove, swelling centrum retracing spring is arranged in the groove of the beam barrel body that expands, mandrel passes from swelling centrum retracing spring center, and the swelling centrum retracing spring other end and swelling centrum compress; With bloated beam barrel body junction, each is bloated, and two ends, the pawl left and right sides are equipped with groove, the pawl retracing spring that expands is arranged in the groove of the pawl that expands, and the spring guidepost passes from the pawl retracing spring that expands, spring guidepost end be fixed on the axle that expands simplified on.
The bloated axle of aforesaid a kind of machinery, its described swelling centrum is the circular conical surface with identical tapering with bloated pawl contact surface.
The bloated axle of aforesaid a kind of machinery, its described swelling centrum is connected with mandrel by screw thread.
Aforesaid a kind of machinery axle that expands, its described axle head by screw retention at bloated beam barrel end of body.
The bloated axle of aforesaid a kind of machinery, its described spring guidepost end is fixed on the beam barrel body that expands by screw thread.
Effect of the present utility model is: the bloated axle of machinery described in the utility model, and the pawl that expands is ejected by the swelling centrum, and the swelling centrum is by carrying out transmission with being threaded of mandrel, and the swelling ability is strong, has auto-lock function, dependable performance after the pawl expansion of expanding.4 bloated pawls are released by the swelling centrum simultaneously, after the swelling of rolls core, and volume core and the mechanical shaft concentricity height that expands.The folding and unfolding spool of associated mechanical such as it can be applicable to be coated with, cut, printing, rewinding, compound, papermaking, plastics.Owing to do not adopt air sac type structure, eliminated the hidden danger of air bag gas leakage, be particluarly suitable for using under the vacuum condition.
Description of drawings
Fig. 1 is the bloated axle construction scheme drawing of machinery described in the utility model.
Fig. 2 is the bloated axle of a machinery shown in Figure 1 A-A cutaway view.
Among the figure: 1 axle head, 2 bloated axles are simplified, 3 swelling centrums, 4 bloated pawls, 5 swelling centrum retracing springs, 6 mandrels, 7 clamp sleeves, 8 bloated pawl retracing springs, 9 spring guideposts, 10 volume cores.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the bloated axle of a kind of machinery described in the utility model is further described.
As shown in Figure 1, the bloated axle of machinery comprises the axle simplified 2 that expands, by screw retention axle head 1 is arranged at bloated beam barrel body 2 front ends, penetrate beam barrel body 2 inside of expanding in the through hole that mandrel 6 has from beam barrel body 2 other ends that expand, and mandrel 6 is fixed on the beam barrel body 2 that expands by clamp sleeve 7.Be arranged with two swelling centrums 3 in mandrel 6 both sides external, beam barrel body 2 inside of expanding, each swelling centrum 3 is connected with mandrel 6 by screw thread, and each swelling centrum 3 periphery is equipped with 4 bloated pawls 4 that can promote to stretch out bloated beam barrel body 2.With each junction, swelling centrum 3 end, the axle simplified 2 that expands on be equipped with groove, swelling centrum retracing spring 5 is arranged in the groove of the axle simplified 2 that expands, mandrel 6 passes from swelling centrum retracing spring 5 centers, swelling centrum retracing spring 5 had directional tagging, swelling centrum retracing spring 5 other ends and swelling centrum 3 compress, thereby swelling centrum 3 is had outside propelling thrust.As shown in Figure 2, with simplified 2 junctions of axle of expanding, each is bloated, and two ends, pawl 4 left and right sides are equipped with groove, the pawl retracing spring 8 that expands is arranged in the groove of the pawl 4 that expands, spring guidepost 9 passes from the pawl retracing spring 8 that expands, play directional tagging, spring guidepost 9 ends are fixed on the axle simplified 2 that expands by screw thread.Described swelling centrum 3 is the circular conical surface with identical tapering with bloated pawl 4 contact surfaces.
Machinery described in the utility model expands axle in use, when rotation mandrel 6, promotes clamp sleeve 7 and inwardly move, drives inwardly motion of swelling centrum 3, by circular conical surface the bloated beam barrel body 2 of 4 bloated pawl 4 expansions.The pawl 4 that expands is ejected by swelling centrum 3, and swelling centrum 3 is by carrying out transmission with being threaded of mandrel 6, and the swelling ability is strong, has auto-lock function, dependable performance after pawl 4 expansions of expanding.After the swelling of rolls core, because 4 bloated pawl expansions simultaneously, volume core and the mechanical shaft concentricity height that expands.
In conjunction with the accompanying drawings embodiment of the present utility model has been done detailed description above, but the utility model is not limited to the foregoing description, in the ken that those of ordinary skills possessed, also can under the prerequisite that does not break away from the utility model aim, make various variations.
