Detailed implementation manners

[0032] The following further elaborates on this application in conjunction with the Figure 3 - attached Figure 5 drawings for a more detailed description.

[0033] An embodiment of this application discloses a welding positioning tooling for sheet metal parts.

[0034] Referring to Figure 3 and Figure 4 , a welding positioning tooling for sheet metal parts includes a fixed base 1. The fixed base 1 includes a fixed pedestal 11 and a positioning plate 12. An irregularly shaped positioning block 121 is integrally formed on the positioning plate 12. There are four positioning blocks 121. Seven welding holes 1211 for avoiding the welding heads are penetrated and opened on any one of the positioning blocks 121 corresponding to the quantity and positions of the welding heads. This ensures that the welding heads can accurately and unobstructedly approach the welding points through the welding holes 1211, thus guaranteeing the welding quality of welding the first sheet metal part 2 and the second sheet metal part 3. A profiling groove 111 similar to the outer contour of the first sheet metal part 2 is provided on the fixed pedestal 11. A mating groove 1111 for embedding and cooperating with the positioning block 121 is penetrated and opened inside the profiling groove 111 of the fixed pedestal 11. The mating groove 1111 is provided with four corresponding to the quantity of the positioning blocks 121. Any one of the positioning blocks 121 on the positioning plate 12 forms an embedding and cooperation with the mating groove 1111 from bottom to top, facilitating the staff to disassemble or install the positioning plate 12.

[0035] Referring to Figure 5 , four first bolts 112 are provided on the fixed pedestal 11. Any one of the first bolts 112 penetrates the fixed pedestal 11 from top to bottom and forms a threaded connection with the positioning plate 12. Two second bolts 122 are provided on the positioning plate 12. Any one of the second bolts 122 penetrates the positioning plate 12 from bottom to top and forms a threaded connection with the fixed pedestal 11. Through the double bolt connection, the reliability of the connection between the fixed pedestal 11 and the positioning plate 12 can be significantly improved.

[0036] Referring to Figure 5 , on the positioning plate 12, there are a first fixing post 123 for fixing the first sheet metal part 2 and a second fixing post 124 for fixing the second sheet metal part 3 in plug-in fit. There are three first fixing posts 123, which are distributed in a triangular shape at the middle position of the profiling groove 111. At the positions and in the same number corresponding to the first fixing posts 123 on the fixing base 11, there are first positioning holes 1112. Any one of the first positioning holes 1112 is communicated with the profiling groove 111. Any one of the first fixing posts 123 forms a plug-in fit with the corresponding first positioning hole 1112. Thus, the first sheet metal part 2 can be fixed on the fixing base 11 through the plug-in fit of the positioning groove 21 and the three first fixing posts 123.

[0037] Referring to Figure 5 , there are two second fixing posts 124. At the positions and in the same number corresponding to the second fixing posts 124 on both outer edges of the profiling groove 111 on the fixing base 11, there are second positioning holes 113. Any one of the second fixing posts 124 forms a plug-in fit with the corresponding second positioning hole 113. Thus, the through hole 31 of the second sheet metal part 3 can be accurately plugged and fitted on the second fixing post 124.

[0038] Referring to Figure 5 , at the top of any one of the first fixing posts 123, there is a first guiding part 1231, which is convenient for the staff to quickly align the first sheet metal part 2 with the first fixing post 123; at the top of any one of the second fixing posts 124, there is a second guiding part 1241, which is convenient for the staff to quickly align the second fixing post 124 with the through hole 31 of the second sheet metal part 3. Thus, the adjustment time is reduced and the work efficiency is improved.

[0039] Referring to Figure 4 , on the fixing base 11, there are clamping mechanisms 114 symmetrically arranged for clamping the second sheet metal part 3. In this embodiment, the clamping mechanism 114 is set as a quick clamp 1141 and there are two quick clamps 1141. Any one of the quick clamps 1141 is connected to the fixing base 11 by bolts in a threaded manner. With the setting of the quick clamp 1141, the staff can accurately position and quickly clamp the second sheet metal part 3. Thus, a reliable fixing method is provided for the second sheet metal part 3, and the accuracy and consistency of welding are further improved.

[0040] Referring to Figure 5 , on the positioning plate 12, there are positioning posts 125 for assisting in fixing the second sheet metal part 3. There are three positioning posts 125. Any one of the positioning posts 125 passes through the fixing base 11, and the side surface of any one of the positioning posts 125 forms an abutting fit with the side surface of the second sheet metal part 3, further enhancing the stability of the second sheet metal part 3 during the welding process and reducing the risk of the second sheet metal part 3 shifting due to vibration.

[0041] Reference Figure 5 As shown in Figure 5 , the fixed base 11 is provided with avoidance holes 1113 penetrating through the profiling groove 111 for avoiding the insertion part 22 of the first sheet metal part 2. There are two avoidance holes 1113, so that the avoidance holes 1113 can avoid the insertion part 22 of the first sheet metal part 2, which helps to reduce the risk of wear of the insertion part 22 of the first sheet metal part 2 due to vibration during the welding process.

[0042] Reference Figure 5 As shown in Figure 5 , an installation opening 115 is penetratingly provided on one side of the fixed base 11 far from the avoidance holes 1113. The installation opening 115 is communicated with the profiling groove 111, which is convenient for the staff to install or adjust the first sheet metal part 2 or the second sheet metal part 3, thereby improving the overall operability.

[0043] Reference Figure 5 As shown in Figure 5 , a first avoidance groove 1114 for avoiding the bent part 23 of the first sheet metal part 2 is provided at the inner edge of the profiling groove 111 of the fixed base 11. The first avoidance groove 1114 is arranged between the avoidance holes 1113 and the installation opening 115; a second avoidance groove 1115 is provided at the inner edge of the profiling groove 111 close to any positioning block 121. The second avoidance groove 1115 is communicated with the first avoidance groove 1114, so that the first avoidance groove 1114 and the second avoidance groove 1115 can avoid the bent part 23 of the first sheet metal part 2, which helps to reduce the risk of wear of the outer edge of the first sheet metal part 2 due to vibration during the welding process.

[0044] The implementation principle of the embodiment of the present application is as follows: During actual operation, the staff first installs and fixes the fixed base 11 and the positioning plate 12, then places the first sheet metal part 2 into the profiling groove 111, and uses the first fixing column 123 to perform preliminary positioning on the first sheet metal part 2. Then, the second sheet metal part 3 is fixed by the second fixing column 124, and the second sheet metal part 3 is clamped by the quick clamp 1141. At the same time, it is ensured that the side surface of the second sheet metal part 3 forms an abutting fit with the side surfaces of the three positioning columns 125 to enhance stability.

[0045] After the staff fixes the first sheet metal part 2 and the second sheet metal part 3 respectively, the welding head passes through the welding hole 1211 and aligns with the welding position, so as to perform welding operations on the first sheet metal part 2 and the second sheet metal part 3.

[0046] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
