[0020] Combination Figure 1 to Figure 2 The utility model is further described as a tool for welding inside a three-knife disc workpiece cover.

[0021] A tool for welding inside a three-disc workpiece cover, characterized in that it comprises a cover positioning component 1 and a baffle positioning component 6.

[0022] The cover body positioning assembly 1 includes a bottom plate 12 for placing the cover body 25 in an inverted state, a pressing plate 11 flatly pressed on the inner bottom surface 21 of the cover body 25 and located on the inner side of the baffle 5 to be welded, and multiple side pressing groups arranged on the bottom plate 12 and arranged along the edge of the cover body 25 and pressed on the top of the side wall of the cover body 25. The baffle positioning assembly 6 has multiple groups and is all arranged on the pressing plate 11, distributed along the welding position of the baffle 5, and each baffle 5 is positioned by at least two groups of baffle positioning assemblies 6 in this embodiment, so that the baffle 5 can be positioned on the inner bottom surface 21 of the cover body 25 in a bent state, and each group of baffle positioning assemblies 6 includes a support seat 61 arranged on the pressing plate 11 and located on the inner side of the baffle 5, a clamp 63 arranged on the top of the support seat 61, and an outer clamp block 62 arranged on the clamp head of the clamp 63 and located on the outer side of the baffle 5, and the outer clamp block 62 cooperates with the support seat 61 to clamp and position the baffle 5.

[0023] Specifically, the bottom plate 12 is provided with a plurality of edge pads 7 for supporting the edge of the cover body 25 and three center pads 8 for supporting the center of the cover body 25, each center pad 8 is provided with a screw rod 9 arranged in a vertical state, and the screw rod 9 is provided with a locking nut 10 for pressing down the pressing plate 11. The position of the screw rod 9 corresponds to the mounting hole on the cover body 25, so that the upper end of the screw rod 9 can pass through the cover body 25, and the pressing plate 11 is also provided with a through hole for the upper end of the screw rod 9 to pass through. When in use, first remove the locking nut 10 from the screw 9, then place the cover body 25 in an inverted state, that is, with the cover opening facing up, on the edge pad 7 and the center pad 8, so that the edge position of the cover body 25 is supported on the edge pad 7, and the three center parts are supported on the three center pads 8, and then place the pressure plate 11 on the inner bottom surface 21 of the cover body 25, and finally install the locking nut 10 and tighten the locking nut 10 so that the pressure plate 11 is pressed flat on the inner bottom surface 21 of the cover body 25 to position and shape the inner bottom surface of the cover body 25.

[0024] In this embodiment, in order to make the pressing plate 11 cover the inner bottom surface of the cover body 25 as much as possible, the contour line of the pressing plate 11 is close to the extension line of the baffle 5 on the inner bottom surface of the cover body 25 .

[0025] The central pad 8 has a positioning pin 13, and the pressure plate 11 has a positioning hole for the positioning pin 13 to pass through. The positioning pin 13 also corresponds to the mounting hole on the cover body 25, so that the positioning pin 13 can pass through the cover body 25 and cooperate with the positioning hole on the pressure plate 11. Through the cooperation between the positioning pin 13 and the positioning hole, it is easy to place and position the cover body 25 on the bottom plate 12, so that the cover body 25 can be placed on the bottom plate 12 quickly and accurately.

[0026] In this embodiment, the cover body 25 is in an inverted state when in the positioning state, so the side walls of the cover body 25 extend upward. At the same time, the side walls of the cover body 25 are divided into an oblique side wall 23 located at the front face position and a vertical side wall 22 located on the left and right sides and the rear side. Therefore, the side pressure group is divided into an oblique side wall pressing group 3 and a vertical side wall pressing group 4.

[0027] The inclined side wall pressing group 3 includes a support plate 33 and a first cylinder 31, and the support plate 33 and the first cylinder 31 are both arranged on the bottom plate 12 and located on the outside of the cover body 25. A first pressing block 32 is connected to the piston rod of the first cylinder 31, and the first pressing block 32 is located above the side wall. After the first cylinder 31 contracts, the first pressing block 32 can be pressed on the top of the inclined side wall 23 to press the inclined side wall of the cover body 25 downward, and the edge position of the cover body 25 is pressed on the edge pad 7 of the bottom plate 12, and at the same time, the outer side surface of the inclined side wall is abutted against the inclined support plate 33 to form a front face edge pressing and positioning.

[0028] The vertical side wall pressing group 4 includes a second cylinder 42 and a second pressing block 41 arranged on the second cylinder 42. The second pressing block 41 is located above the vertical side wall 22. After the second cylinder 42 contracts, the second pressing block 41 is pressed on the top of the vertical side wall, pressing the vertical side wall of the cover body 25 downward, and pressing the edge position of the cover body 25 on the edge pad 7 of the bottom plate 12, thereby pressing and positioning the left and right sides and the rear side of the cover body 25.

[0029] The support seat 61 includes a base 611 disposed at the edge of the pressure plate 11 and an inner clamping block 612 disposed on the outer surface of the base 611. The surfaces of the inner clamping block 612 and the outer clamping block 62 facing each other are adapted to the shapes of the inner and outer side surfaces of the baffle 5, so that the inner clamping block 612 and the outer clamping block 62 can fit and clamp the baffle 5. The inner clamping block 612 can be disassembled relative to the base 611, and the outer clamping block 62 can be disassembled relative to the clamp 63, that is, the inner clamping block 612 is fixed to the base 611 by bolts, and the outer clamping block 62 is fixed to the clamp head of the clamp 63 by bolts, so that the inner clamping block 612 and the outer clamping block 62 are easily replaced.

[0030] In this embodiment, the clamp 63 is of prior art, which mainly includes a mounting seat, a chuck installed on the mounting seat and extending forward, and a driving handle installed on the mounting seat and extending backward. The front end of the chuck extends to the outside of the baffle 5 for the installation of the outer clamp block 62, and the mounting seat is arranged on the top of the base 611.

[0031] During specific use, a positioning groove is provided on the inner bottom surface 21 of the cover body 25, and a pin is provided at the bottom of the baffle 5. The baffle 5 is initially positioned on the inner bottom surface of the cover body 25 through the pin and the positioning groove, and then the baffle 5 is stably and accurately fixed on the cover body 25 through the cover body positioning component 1 and the baffle positioning component 6, so as to realize the overall positioning of the three-disc workpiece 2 without the need for manual hand-held positioning by workers, which significantly improves the convenience and accuracy of welding; the pressure plate 11 is flatly pressed on the inner bottom surface of the inverted cover body 25, which can shape and position the cover body 25, and avoid the problem of deformation of the cover body 25 due to lateral pressure.

[0032] In this embodiment, the cover body 25 is placed upside down, while the first two processes, i.e., the first and second processes, are placed upright. Therefore, this embodiment can also perform repair welding on the parts that are inconvenient to weld in the first two processes, such as repair welding the weld 14 between the reinforcement strip and the side wall of the cover body 25.
