Description
Technical field
The utility model is related to assembling construction aid field, the especially a kind of adjustable resistance heating of diameter used
Device.
Background technology
Spool shaft is typically designed with the axis hole on reel using the build-up tolerance of interference in headstock gear roll device, it is ensured that axle
With the tight fit in hole, thus a difficult problem is brought to assembling, generally using freezing assembling method, exactly freezed on axle, from
And the diameter of axle is reduced, then in place, i.e. assembling is completed after temperature recovery for rapid assembling.The method needs the space chi of freezing equipment
The very little appearance and size for meeting axle is required, so higher to equipment requirement；It is exactly by reel there is a method in which being exactly hot assembling method
Axis hole is heated, and so as to expand aperture, then in place, the i.e. assembling after temperature cooling is completed for rapid assembling.The method pair sets
It is relatively low for requiring, it is more easy to promote.
Heating assembling method will control the uniformity of heating in heating process, and common flame heating it is difficult to ensure that,
Therefore a kind of special heater is needed, adapts to the heating needs of different pore size in certain limit.
There is presently no this heater that can within the specific limits adapt to different pore size heating needs.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of adjustable resistance heater of diameter, can solve
The complicated problem of different pore size heating operation, diameter can as needed, and appropriate adjustment can just meet assembling needs.Using spirit
It is living, save substantial amounts of manpower, financial resources, material resources；And it is reusable, reduce investment outlay.
To solve above-mentioned technical problem, the technical scheme that the utility model is adopted is：A kind of adjustable resistance of diameter
Heater, including adjusting rod, are arranged with screw mandrel outside adjusting rod, adjusting nut is arranged with screw mandrel, and adjusting nut is fixedly mounted on
In active ring free bearing, fixed hinged seat middle part with regulation boom end be connected, the fixed hinged seat other end along the circumferential direction with multiple " X " types
First pole of bracing frame one end is hinged, and second pole of " X " type bracing frame one end is hinged with active ring free bearing, each " X " type
Heating plate of the bracing frame other end with cross section for circular arc is hinged, and the cross section of multiple heating plates is located at and is with adjusting rod center
On the circumference of the circle in the center of circle.
Annular guide pad is arranged with active ring free bearing.
The quantity of " X " type bracing frame is three.
The adjustable resistance heater of diameter that the utility model is provided, using adjusting nut so that active ring free bearing is along silk
Bar is moved, so as to control the opening degree of each " X " type bracing frame, so as to reach the diameter of a circle of the composition for adjusting multiple heating plates
Change to meet different aperture heating needs, complete whole assembling process；Different pore size heating operation complexity can be solved
Problem, diameter can as needed, and appropriate adjustment can just meet assembling needs；Using flexible, save substantial amounts of manpower, financial resources,
Material resources；And it is reusable, reduce investment outlay；The design of annular guide pad serves the effect for preventing active ring free bearing from rotating.
Description of the drawings
With reference to the accompanying drawings and examples the utility model is described in further detail：
Fig. 1 is right view of the present utility model；
Fig. 2 is the A-A of the utility model Fig. 1 to sectional view.
Specific embodiment
As illustrated in fig. 1 and 2, it is arranged with silk outside the adjustable resistance heater of a kind of diameter, including adjusting rod 1, adjusting rod 1
Bar 2, is arranged with adjusting nut 3 on screw mandrel 2, adjusting nut 3 is fixedly mounted in active ring free bearing 4, with tune in the middle part of fixed hinged seat 6
The end of pole 1 connects, and the outward flange of fixed hinged seat 6 is along the circumferential direction cut with scissors with the first pole 7-1 of multiple one end of " X " type bracing frame 7
Connect, the second pole 7-2 of the one end of " X " type bracing frame 7 is hinged with active ring free bearing 4, each other end of " X " type bracing frame 7 with it is horizontal
Section is hinged for the heating plate 8 of circular arc, and the cross section of multiple heating plates 8 is located at the circumference of the circle with adjusting rod center as the center of circle
On.
Annular guide pad 5 is arranged with active ring free bearing 4.
The quantity of " X " type bracing frame 7 is three, and the quantity of heating plate 8 is also three.
Multiple heating plates 8 are connected by wire with plug.
The course of work of the present utility model is as follows：
Active ring free bearing 4 is adjusted in the presence of annular guide pad 5, move along screw mandrel 2 when using using adjusting nut 3,
So as to adjust the distance of active ring free bearing 4 and fixed hinged seat 6, the opening degree of " X " type bracing frame 7 is controlled, so as to reach multiple adding
The diameter of a circle of the composition of hot plate 8 changes to meet different aperture heating needs, and the circle of the composition of multiple heating plates 8 is fixed
On the surface of the endoporus that need to be heated, endoporus is uniformly heated, after endoporus heating in place, the utility model is taken out rapidly, enter
The assembling of row axle, completes whole assembling process.
Can solve the problems, such as that different pore size heating operation is complicated, diameter can as needed, and appropriate adjustment just can meet
Assembling needs.Using flexible, substantial amounts of manpower, financial resources, material resources are saved；And it is reusable, reduce investment outlay.
