The specific implementation mode is as follows:

the utility model will now be further described by way of specific examples, with reference to figures 1 to 4:

the utility model relates to a riding wheel device suitable for a plate tailor-welding occasion, which is mainly characterized in that: the device comprises a circular wheel-shaped supporting wheel 1 and a rotating shaft 2 in a shaft structure shape, wherein the supporting wheel 1 and the rotating shaft 2 are coaxially arranged in a layout relationship. The supporting roller 1 and the rotating shaft 2 have an assembly relationship of direct connection or indirect connection, wherein the connection relationship can have three conditions: 1) the riding wheel 1 can be directly sleeved on the rotating shaft 2 in a rotating way, or the riding wheel 1 can be indirectly sleeved on the rotating shaft 2 in a rotating way (not shown in the figure), namely, the riding wheel 1 can rotate relative to the rotating shaft 2; 2) the riding wheel 1 is tightly sleeved on the rotating shaft 2 (not shown in the figure), and the riding wheel 1 and the rotating shaft 2 rotate together at the moment; 3) the supporting roller 1 and the rotating shaft 2 are manufactured as an integral structure (not shown in the figure), and the supporting roller 1 and the rotating shaft 2 rotate together. No matter the connection relationship between the idler 1 and the rotating shaft 2 is in the above three cases, the idler 1 can rotate around the axis thereof, and the rotating shaft 2 can be a rotating member or a fixed member (which can be set according to actual needs). It should be noted that the riding wheel 1 of the present invention can be a single piece (not shown) or an assembly, and fig. 1 and 4 show the riding wheel 1 in the case of an assembly: namely, the riding wheel 1 consists of a riding wheel body 1a, a riding wheel shaft core 1b and a riding wheel sealing cover 1 c. It is the idler 1 that can perform the rotary motion, so the utility model can realize that the welding equipment can perform the welding on the welding seams 3 with various lengths and can ensure the welding quality: referring to fig. 3, the target plate weldment 4 is placed on the welding bench and moves along with the conveying device (the target plate weldment 4 can also move by the rotation of the riding wheel 1), and meanwhile, the welding gun 5 is arranged on one side of the target plate weldment 4 to be spliced and welds the target plate weldment 4, while the riding wheel 1 of the utility model is arranged on the other side of the target plate weldment 4 (the side is opposite to the partition board of the welding gun 5) and supports the target plate weldment 4, and at this time, the target plate weldment 4 moves and moves by the driving of the conveying device or/and the rotating wheel 1, so that the weld 3 obtained by welding the target plate weldment 4 also extends, and due to the rotatability of the riding wheel 1, the riding wheel 1 and the target plate weldment 4 can always keep good contact in the welding process, in other words, the riding wheel 1 can perform and complete the holding of the target plate weldment 4 when welding the weld 3 with different lengths are welded in the welding process And the riding wheel 1 and the target plate weldment 4 are not easy to slide excessively to cause mutual damage, so that the welding quality of the welding seam 3 can be ensured.

In order to obtain better welding quality of the welding seam 3, a cooling channel 6 through which a cooling medium can pass can be arranged inside the riding wheel 1 or/and inside the rotating shaft 2, and the situation shown in fig. 4 is the situation that the cooling channel 6 is arranged inside the riding wheel 1. It is clear that by providing the cooling channels 6, the heat generated by the welding can be removed by means of various cooling media, which in turn provides an effective cooling of the weld seam 3 and thus promotes an improved welding quality. Here, the cooling medium may be water, air or even oil or other cooling liquid, wherein water is preferred as the cooling medium because water has the advantages of carrying more heat and being more economical and widely available, and the operation and maintenance thereof are relatively simple. Furthermore, in order to facilitate the manufacture and the later maintenance, the utility model can also be provided with at least one distribution hub 7 beside the shaft of the riding wheel 1, wherein the side of the shaft is arranged along the axial direction of the riding wheel 1 and is distributed adjacent to the riding wheel 1, and the distribution hub 7 is provided with a special switching channel 8 to be communicated with the cooling channel 6 on the riding wheel 1 (see fig. 1 and 4). It should be noted that the switching channel 8 of the distribution hub 7 can take various forms to connect the cooling medium into or/and out of the cooling channel 6 inside the riding wheel 1, that is, the switching channel 8 of the distribution hub 7 in the present invention can take an axial flow form, a radial flow form or a mixture form of the axial flow and the radial flow to communicate with the cooling channel 6, and fig. 4 shows that the switching channel 8 communicates with the cooling channel 6 in the radial flow form. It should also be noted that when the cooling channel 6 comprises a flow channel structure (not shown) for guiding the cooling medium to form a circular flow inside the idler 1, the cooling medium will have a better cooling effect on the idler 1 and thus on the weld 3.

In the present invention, the distribution hub 7 and the rotating shaft 2 may be a rotatable member or a stationary member. In particular, it is preferred that both the distribution hub 7 and the shaft 2 are stationary (as is the case with the embodiment shown in fig. 1 to 4), at which time the distribution hub 7 and the shaft 2 can be arranged very conveniently and can be well adapted to the operation of the welding apparatus. Whether the distribution hub 7 and the rotating shaft 2 are rotatable rotating parts or non-rotatable fixed parts, the arrangement of the shaft seal 9 between the riding wheel 1 and the distribution hub 7 or/and between the riding wheel 1 and the rotating shaft 2 can bring about the positive effect of preventing the cooling medium from leaking, which is advantageous for improving the operational reliability of the welding equipment device, as shown in fig. 1 and 4. In particular, the distribution hubs 7 according to the utility model are provided in total with two distribution hubs, one distribution hub 7 being responsible for supplying the idler 1 with cooling medium and the other distribution hub 7 being responsible for receiving the cooling medium from the idler 1, as is the case with the embodiments shown in fig. 1 to 4, which is advantageous for the layout of the cooling system of the welding apparatus and for the later maintenance.

The present invention may be provided with a driving motor 10, wherein the driving motor 10 can drive the supporting roller 1 to rotate through a transmission device 11 (see fig. 1 to 3), so that the supporting roller 1 becomes a power source or a driving member for driving the target plate weldment 4 to displace. It should be noted that the transmission device 11 of the present invention can be various transmission components or transmission mechanisms in the prior art, and the transmission device 11 shown in fig. 1 to 4 includes a timing belt 11a and a timing pulley 11b commonly used in the mechanical field, and in addition, can be other transmission mechanisms such as a gear transmission, etc. In addition, a rolling bearing 12, a bearing housing 13, and a bracket 14 may be further provided for the convenience of supporting the device.

In order to facilitate and adapt to the formation and shaping of the welding seam 3, the utility model can also open a ring groove-shaped groove 15 at the outer circular rim of the riding wheel 1 (see fig. 1, 2 and 4). Furthermore, a spray gun 16 for spraying a protective medium or a cooling medium can be provided, the nozzle of the spray gun 16 being directed at the groove 15 of the idler 1. The protective medium may be any of various inert gases such as nitrogen, argon, carbon dioxide, etc., or any of various other liquid or dry powder materials that have corrosion resistance, adhesion resistance, or adhesion resistance. It is easy to understand that, by arranging the annular groove 15 on the riding wheel 1 and by implementing cooling means and protection means, the forming quality of the welding seam 3 is ensured, the timely cooling of the welding seam 3 is also ensured, meanwhile, the damage degree of the riding wheel 1, the welding seam 3 and the target plate weldment 4 is also reduced, and as a result, the quality of the welding seam 3 is favorably improved.

The rotatable riding wheel 1 is adopted to support the target plate weldment 4, so that the supporting task requirements of welding seams 3 with different lengths can be met in the welding process, and the adaptability of welding equipment to welding seams 3 with various lengths can be effectively improved; moreover, the riding wheel 1 can be conveniently aligned to the welding position of the welding gun 5 and supports the target plate weldment 4, so that the support firmness of the weldment at the welding position can be kept in the welding process, and the working reliability of supporting the weldment when the welding equipment performs welding work can be effectively improved; further, by arranging the annular groove 15 on the riding wheel 1 and particularly by implementing a cooling means and a protection means, on one hand, the forming quality of the welding seam 3 is ensured, on the other hand, the timely cooling of the welding seam 3 is ensured, and the damage degree of the riding wheel 1, the welding seam 3 and the target plate weldment 4 is reduced, so that the consistency of quality acquisition of the welding seam 3 when the welding equipment performs plate tailor welding can be effectively improved.

The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so: equivalent changes made according to the shape, structure and principle of the utility model are all covered by the protection scope of the utility model.
