Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the positional and orientational relationships indicated as "upper", "lower", "left", "right", "front", "rear", "vertical", "bottom", "inner", "outer", etc. are based on the positional and orientational relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
As shown in fig. 1 to 4, an assembling mechanism of a tire and a hub in a hub motor includes:
a base 1;
the placing plate 2 is fixed on the base 1, the placing plate 2 is provided with a through hole 21 and an avoiding hole 22 communicated with the through hole 21, the avoiding hole 22 extends along the radial direction of the through hole 21, the placing plate 2 is provided with an annular boss 23, the annular boss 23 is arranged around the through hole 21 in a surrounding manner, and an interval exists between the inner ring of the annular boss 23 and the through hole 21;
the fixed plate 3 is positioned below the placing plate 2, and the fixed plate 3 is vertically and slidably arranged on the base 1;
the first air cylinder 4 is fixed on the base 1, and an output shaft of the first air cylinder 4 is connected with the fixing plate 3;
tire tension assembly, tire tension assembly circumference interval are provided with the multiunit, and tire tension assembly includes second cylinder 5 and stretching plate 6, and stretching plate 6 is fixed on second cylinder 5, and second cylinder 5 is fixed on fixed plate 3, and stretching plate 6 passes and places board 2, and stretching plate 6 is located the corresponding department of dodging hole 22.
Thus, the tire is placed on the annular boss 23, then the second cylinder 5 is started to promote the stretching plate 6 to slide, the tire is stretched by the stretching plate 6, the inner diameter of the tire is increased, then the hub is placed at the interval part between the through hole 21 and the annular boss 23, then the first cylinder 4 is started to promote the fixing plate 3 to descend, so that the stretching plate 6 also descends and finally breaks away from the tire, the tire contracts under the elastic effect to tightly hold the hub, the assembly of the tire and the hub is conveniently completed, the production efficiency is improved, the annular boss 23 aims to ensure that the width of the tire is smaller than that of the hub, and therefore multiple tires are required to be heightened to accurately assemble the hub.
In addition, four groups of tire stretching assemblies are arranged at intervals in the circumferential direction, and the tire stretching assemblies are arranged at equal intervals.
Thus, the tire can be satisfactorily expanded.
In addition, still include the direction subassembly, the direction subassembly includes uide bushing 7 and guide bar 8, and uide bushing 7 is fixed on base 1, and guide bar 8 is fixed on fixed plate 3, and guide bar 8 cooperates in uide bushing 7.
Thus, the fixed plate 3 can be stably oriented to slide.
In addition, the side of the stretching plate 6 close to the annular boss 23 is arc-shaped.
In this way, the side of the stretching plate 6 close to the annular boss 23 is the contact part of the stretching plate 6 and the tire inner ring, and the contact part is arranged in an arc shape and is matched with the shape of the tire, so that the stretching effect is good, and the damage to the tire can be reduced.
In addition, the fixing device further comprises a fixing assembly, the fixing assembly comprises a third air cylinder 9 and a pressing plate 10, the third air cylinder 9 is fixed on the outer side of the annular boss 23, an output shaft of the third air cylinder 9 faces the annular boss 23, the pressing plate 10 comprises a fixing portion 101 and a pressing portion 102, and the fixing portion 101 is fixedly connected with the output shaft of the third air cylinder 9.
Thus, when the stretching plate 6 is separated from the inner ring of the tire downwards, the third air cylinder 9 causes the pressing plate 10 to press on the tire, and the tire is prevented from sliding upwards to influence the assembly accuracy.
In addition, the pressing portion 102 is provided obliquely.
Thus, if the size of the pressing plate is wrong, the pressing plate 10 cannot be pressed on the tire or a gap exists between the pressing plate and the tire, and the pressing part 102 is obliquely arranged, so that the situation can be avoided to a great extent, and a better fixing effect can be obtained.
In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
