Description

Technical Field

[0001] The utility model relates to the technical field of sealing wheels, in particular to a sealing wheel for fuel tank sealing. Background Art

[0002] The sealing process of the fuel tank is one of the most core processes in fuel tank production. The main sheet and end cap sheet of the fuel tank to be processed are placed on the rotating clamping component of the equipment. The rotating clamping component can rotate and fix the workpiece. When the sealing wheel advances radially, with the help of rotation, the groove curve bends the periphery of the end cap sheet into a certain shape, so that it hooks with the flanging flange of the main sheet of the fuel tank deformed by the lower tray force, and bends and extrudes. Finally, the main sheet and end cap sheet of the fuel tank are curled and tightly connected together to form a sealed fuel tank seal.

[0003] For the sealing wheel, the selection of its groove curve is crucial. Different sizes of groove curves can bend the periphery of the end cap sheet into different numbers of turns. For different production requirements, sealing wheels with different groove sizes need to be used. Therefore, the sealing wheel needs to be replaced in a timely manner.

[0004] In the prior art, the sealing wheel is often removed from the driving rotating shaft of the equipment, and then a new sealing wheel that meets the size requirements is installed. The replacement process is very troublesome, time-consuming and laborious, causing inconvenience to the staff. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Please refer to Figures 1-3 , the present invention discloses a sealing wheel for fuel tank sealing, which is composed of an outer wheel 100 and a sleeve 200. Among them, an installation hole is provided at the center of the outer wheel 100, and the outer wheel 100 is composed of a large wheel 101, a first acting wheel 102, a second acting wheel 103 and a small wheel 104 that are coaxially connected in sequence and form an integral structure; the sleeve 200 is composed of a pipe body 201 and two limiting rings 202, and the two limiting rings 202 are respectively fixedly installed on the outer sides of both ends of the pipe body 201; the pipe body 201 is movably inserted into the installation hole of the outer wheel 100, and the outer wheel 100 can move along the pipe body 201. Under the limiting action of the two limiting rings 202, the outer wheel 100 will not slip off the pipe body 201.

[0026] Please refer to Figure 4 , two groups of positioning holes are provided on the outer surface of the pipe body 201. Each group of positioning holes includes four 203 circumferentially distributed on the outer side of the pipe body 201 in a circle. A number of jacks corresponding to the four 203 in a group of positioning holes are provided on the large wheel 101. Each jack and the 203 corresponding to the jack form a communicating through hole. Internal threads are provided on the inner wall of the through hole, and a fixing bolt 300 is threadedly inserted into each through hole, thereby fixing the large wheel 101 on the pipe body 201, that is, fixing the outer wheel 100 on the pipe body 201.

[0027] It should be noted that the number of 203 in each group of positioning holes is not limited to four in the present invention, and no specific limit is made to this number, and it can be determined according to actual application requirements. For example, in other embodiments, the number of 203 can also be five, six, seven...

[0028] Please refer toFigure 5 Since there are two sets of positioning holes, the large wheel 101 can be positioned in two different sets of positioning holes as needed. When adjusting the position, only rotate the fixing bolt 300 to disengage the bottom of the fixing bolt 300 from 203, then the positioning of the large wheel 101 on the pipe body 201 can be released. Subsequently, move the outer wheel 100 on the pipe body 201 so that the fixing bolt 300 on the large wheel 101 corresponds to 203 in the other set of positioning holes one by one, and then rotate the fixing bolt 300 into the corresponding 203, and the large wheel 101 can be fixed on the pipe body 201, thereby realizing the position adjustment of the outer wheel 100; the part of the large wheel 101 located at the outer end of the jack is set as a plane to fit with the inner side of the nut of the fixing bolt 300, enhancing the fixing strength of the fixing bolt 300.

[0029] To facilitate quickly moving the large wheel 101 to the corresponding position of the other set of positioning holes during adjustment, the difference between the distance between the two sets of limiting rings 202 and the overall length distance of the outer wheel 100 is set as the sum of the center distances of the two sets of positioning holes. In this way, when it is necessary to make the large wheel 101 correspond to one of the sets of positioning holes, only need to move the outer wheel 100 until the large wheel 101 contacts the nearby limiting ring 202, or the small wheel 104 contacts the other limiting ring 202, which is convenient and fast.

[0030] Arc grooves are provided on the outer circumferences of both the first driving wheel 102 and the second driving wheel 103, and the diameters of the two arc grooves are different. Among them, the size of the arc groove of the first driving wheel 102 is R4, and the size of the arc groove of the second driving wheel 103 is R3.

[0031] The working principle of the present utility model:

[0032] During use, fix and install the sealing wheel on the driving rotating shaft through the pipe body 201, adjust the position of the outer wheel 100 on the pipe body 201 so that the small wheel 104 fits with the nearby limiting ring 202. At this time, the first driving wheel 102 is at the working height; when the body sheet and the upper end cover sheet of the fuel tank are gradually fitted, the sealing wheel gradually advances towards the edge of the sheet, and through the rotation of the first driving wheel 102, the two are precisely combined to form a curl of 5-7°. Since the size of the arc groove of the first driving wheel 102 is exactly R4, it can just make the material finish winding to achieve the effect of 5 turns, which can enhance the bonding strength and sealing performance between the body sheet and the upper end cover sheet of the fuel tank, and meet higher air outlet requirements; when it is necessary to seal the body sheet and the upper end cover sheet of the fuel tank with other requirements, the second driving wheel 103 can be adjusted to the working height by changing the position of the outer wheel 100 on the pipe body 201. Only need to adjust the outer wheel 100 through the fixing bolt 300, without replacing the wheel body on the driving rotating shaft, which is time-saving, labor-saving, convenient and fast, and has strong practicability.
