[0031] like Figure 1-Figure 4 As shown, the utility model specifically relates to a main frame rail welding tool for a combine harvester, comprising a base 100 and a main frame rail arranged on the base 100, wherein the main frame rail comprises a transverse tube 200, a first connecting bracket 220 arranged at the end of the transverse tube 200, and a plurality of second connecting brackets 210 arranged at one side of the transverse tube 200;

[0032] The base 100 is provided with a receiving bracket capable of supporting the transverse tube 200, and a first connecting component 110 is provided on one side of the receiving bracket;

[0033] The second connecting bracket 210 includes a sleeve 211 passing through the transverse tube 200 and a connecting plate 212 sleeved on the surface of the sleeve 211 and abutting against the transverse tube 200;

[0034] The first connecting assembly 110 includes a fixing block 111, an auxiliary shaft 112 arranged on one side of the fixing block 111, and a positioning shaft 113 used in conjunction with the auxiliary shaft 112. One end of the sleeve 211 passes through the cross tube 200 and abuts against the auxiliary shaft 112. The other end of the sleeve 211 is connected to the positioning shaft 113 to position the sleeve 211.

[0035] It should be noted that the main frame guide rail is assembled by welding a plurality of components, and the supporting bracket 150 and the first connecting assembly 110 are both fixed to the base 100 by bolts.

[0036] First, the cross tube 200 is placed on the supporting bracket 150, and the position of the cross tube 200 is preliminarily defined by the supporting bracket 150. At the same time, one end of the sleeve 211 is passed through the connecting plate 212 and the cross tube 200 in sequence, and one end of the sleeve 211 extends out of the cross tube 200 and abuts against the auxiliary shaft 112, and the position of the sleeve 211 relative to the cross tube 200 is defined by the auxiliary shaft 112; at this time, the positioning shaft 113 is inserted into the other end of the sleeve 211, so that the positioning shaft 113 is connected to the auxiliary shaft 112, and the positioning shaft 113 and the auxiliary shaft 112 cooperate with each other to support and position the sleeve 211 and the cross tube 200. At the same time, the personnel moves the connecting plate 212 along the length direction of the sleeve 211, so that the connecting plate 212 abuts against the cross tube 200. At this time, the connecting plate 212 and the sleeve 211 have been positioned, and the personnel weld the connecting plate 212 and the sleeve 211.

[0037] The positioning shaft 113 is threadedly connected to the auxiliary shaft 112 .

[0038] The positioning shaft 113 is threadedly connected to the auxiliary shaft 112 to fix the sleeve 211 between the positioning shaft 113 and the auxiliary shaft 112 , and further define the position of the sleeve 211 relative to the cross tube 200 to ensure assembly accuracy.

[0039] A rotating handle 114 is provided at one end of the positioning shaft 113 to facilitate personnel to rotate the positioning shaft 113 so as to assemble the positioning shaft 113 with the auxiliary shaft 112 .

[0040] The first connecting bracket 220 includes a fixing rod 221 and a sleeve 211 arranged on the fixing rod 221. The base 100 is provided with a limiting bracket 130 used in conjunction with the fixing rod 221. The limiting bracket 130 is provided with a second connecting component 140 used in conjunction with the sleeve 211 to position and connect the sleeve 211 with the fixing rod 221.

[0041] It should be noted that when the cross tube 200 is placed on the supporting bracket 150, the fixing rod 221 is synchronously abutted against the limiting bracket 130 to further limit the position of the cross tube 200. When the position of the cross tube 200 is determined, the bushing 211 is assembled on the fixing rod 221 through the second connecting assembly 140 to support and position the bushing 211, making it convenient for personnel to weld the bushing 211.

[0042] The structure of the second connecting component 140 is the same as that of the first connecting component 110 .

[0043] The usage of the second connection component 140 is the same as that of the first connection component 110. The usage of the first connection component 110 has been described in detail above, so it will not be described in detail here.

[0044] There are multiple first connection components 110, and the multiple first connection components 110 correspond to the second connection brackets 210 one by one to ensure the assembly accuracy of the multiple shaft sleeves 211, thereby ensuring the subsequent assembly accuracy of the main frame guide rail.

[0045] The main frame guide rail is also provided with a connecting block 230, and the base 100 is provided with a stopper assembly 120 used in conjunction with the connecting block 230; the stopper assembly 120 includes a bearing block 121 and a vertical block 122, and the vertical block 122 is arranged on one side of the bearing block 121 and forms a limiting groove for placing the connecting block 230.

[0046] When the position of the cross tube 200 on the bearing bracket 150 is determined, the connecting block 230 is placed on the bearing block 121 at the same time, and the vertical block 122 is located on one side of the connecting block 230. The position of the connecting block 230 is determined by the limiting groove formed between the vertical block 122 and the bearing block 121. At this time, since the connecting block 230 is supported and positioned by the bearing block 121 and the stop block, the personnel can free their hands and directly weld the connecting block 230.

[0047] The main frame guide rails are assembled by welding.

[0048] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the present invention, and should all be covered within the protection scope of the present invention.
