Away from the base 1, the four groups of positioning units 2 are all connected to the side of the horizontal plate 22 facing away from the base 1, and the four groups of positioning units 2 are located at the four vertices of the square area, and the four groups of positioning units 2 are all connected with positioning pins 24 for positioning the power controller bracket 4; wherein, a clamping interval is formed between the pressure plate 34 and the four groups of positioning units 2, and the pressure plate 34 can approach or move away from the four groups of positioning units 2 under the drive of the cylinder 31 to increase or decrease the clamping interval accordingly; the horizontal plate 22 can approach or move away from the pressure plate 34 under the drive of the compression cylinder 21 to increase or decrease the clamping interval accordingly.

[0039] In this embodiment, the base 1 is a rectangular thick steel plate with a certain weight and size and a plurality of mounting holes. On the one hand, it provides a reliable counterweight level platform for the tooling arranged thereon to prevent the tooling from being top-heavy and tilting; on the other hand, it provides assembly holes for tooling components (such as positioning components, clamping units 3, etc.) to be fixed on the base 1 by bolts 37, pins, nails, etc.

[0040] It should be understood that the base 1 is used to provide a support platform for the supporting power controller bracket 4 and the tooling to ensure stability and accuracy. The positioning unit 2 is used to provide accurate positioning of the power controller bracket 4 to ensure that the power controller is assembled on the power controller bracket 4. The clamping unit 3 is used to firmly clamp the positioned power controller bracket 4 on the box beam 5 to ensure that no displacement or misalignment occurs during the welding process.

[0041] In the utility model, when welding the power controller bracket 4, firstly, the base 1 of the welding tool is placed on the flat ground, ensuring that the clamping unit 3 is in the open state, and the box beam 5 of the power controller is placed on a specific tool fixture to ensure that it is firmly fastened; secondly, four power controller brackets 4 are placed on four groups of positioning units 2 respectively, ensuring that the positioning pins 24 pass through the power controller bracket 4, and then the box beam 5 and the power controller bracket 4 are matched by adjusting the compression cylinder 21; again, the clamping unit 3 is started by starting the cylinder 31 to start working, so as to reduce the clamping interval, and the pressure plate 34 is pressed and fitted on the power controller bracket 4 to reach a weldable state; finally, the welding is completed according to the design requirements, and the cylinder 31 is started again to increase the clamping interval, and the assembly of the box beam 5 and the power controller bracket 4 is taken out, and the state of waiting for inspection and storage can be reached. Therefore, the welding tool has a compact structure, and when welding the power controller bracket 4, the positioning is accurate, the clamping is firm, and the operation is convenient.

[0042] Furthermore, combined with Figures 10 to 14 As shown, the positioning unit 2 includes a support block 25 and multiple sets of conversion blocks 23. The support block 25 is connected to the horizontal plate 22 through the multiple sets of conversion blocks 23. The support block 25 is provided with a positioning pin 24. The conversion blocks 23 are connected to each other, and the conversion blocks 23 are all in an "L" shape. Among them, the horizontal plate 22 can provide the same horizontal reference platform for the conversion blocks 23 at four positions, thereby improving the consistency control of the position of the power controller bracket 4. Through the connection and conversion of multiple sets of conversion blocks 23, the positioning pin 24 and the support block 25 can be pre-connected at the required position.

[0043] Furthermore, the horizontal plate 22 is parallel to the base 1 to ensure that the power controller bracket 4 is in a horizontal plane during welding.

[0044] Furthermore, the horizontal plate 22 is a "cross" structure, two of the four groups of positioning units 2 are arranged on one side of two opposite sides of the horizontal plate 22, and are spaced apart from each other, and the other two of the four groups of positioning units 2 are arranged on the other side of two opposite sides of the horizontal plate 22, and are spaced apart from each other, so that the four groups of positioning units 2 can be arranged symmetrically. Among them, the distance between two adjacent positioning units 2 in the two groups of positioning units 2 is equal.

[0045] Furthermore, the pressure plate 34 includes a connecting part and a clamping part, one end of the connecting part is connected to the clamping part, and the other end of the connecting part is connected to the rocking plate 33 and the cylinder 31, and the connection point between the rocking plate 33 and the connecting part is located between the clamping part and the cylinder 31, thereby utilizing the lever principle to achieve synchronous clamping or loosening of the four power controller brackets 4.

[0046] Furthermore, the connecting portion is in a "Z"-shaped structure to facilitate the arrangement of the connecting portion.

[0047] Furthermore, the clamping portion includes a transverse section, a first vertical section and a second vertical section that are relatively arranged, one end of the transverse section is connected to the middle area of ​​the first vertical section, the other end of the transverse section is connected to the middle area of ​​the second vertical section, and the middle area connecting part of the transverse section is connected; wherein, both ends of the first vertical section correspond to two groups of positioning units 2 among the four groups of positioning units 2; both ends of the second vertical section correspond to the other two groups of positioning units 2 among the four groups of positioning units 2, thereby allowing the four power supply controller brackets 4 to be subjected to uniform force.

[0048] Furthermore, combined with Fig. 9 , Figures 15 to 17 As shown, the pressure plate 34 also includes a plurality of pressure blocks 35, some of which are protruded one by one at the two ends of the first vertical section toward the direction of the base 1, and another portion of the pressure blocks 35 are protruded one by one at the two ends of the second vertical section toward the direction of the base 1, so that the four power controller brackets 4 can be evenly stressed.

[0049] Furthermore, in order to solve the problem of insufficient rigidity of the pressing unit 3 during the pressing process, the pressing plate 34 further includes a triangular reinforcement block 36, which is connected to the transverse section and the connecting portion.

[0050] In this embodiment, combined with Figures 1 to 9As shown, the power controller bracket 4 is a quasi-Slot type, and there are four of them, each with the same structural size, and each is provided with a lap surface 41, a hole 42, and a fitting surface 43. Among them, the lap surface 41 matches the box beam 5 and is connected to the box beam 5 by welding. The hole 42 is a round hole, which can pass through the above-mentioned positioning pin 24 to achieve spatial positioning of the power controller bracket 4. The fitting surface 43 can achieve a close fit between the power controller bracket 4 and the above-mentioned pressing block 355, avoiding looseness during the welding process, resulting in failure of the assembly size.

[0051] In addition, the box beam 5 is a rectangular profile structure, and there is no need to develop a special mold, which can save a lot of development costs to a certain extent. It is provided with three key features: hole 2 51, hole 3 52 and welding surface 2 53. Among them, hole 2 51 is a circular hole, which can be used as the main positioning hole for welding positioning of the box beam 5. Hole 3 52 is an oblong hole, which can be used as a secondary positioning hole for welding positioning of the box beam 5. Welding surface 2 53 is a transition curved surface, connecting the belly surface and the wing surface of the box beam 5, matching the above-mentioned overlap surface 1 41, and can realize the effective connection between the box beam 5 and the above-mentioned bracket 4.

[0052] For the power controller bracket 4 and its tooling, the preferred operation process of welding the tooling is as follows:

[0053] First, place the base 1 of the welding tool on the flat ground, ensure that the clamping unit 3 is in the open state, and place the box beam 5 on a specific tooling fixture to ensure that it is firmly fastened; secondly, take four power controller brackets 4 and place them on the positioning unit 2 respectively, ensure that the positioning pin 24 passes through the hole 42, and the inner groove of the power controller bracket 4 is horizontally placed on the support block 25, and adjust the compression cylinder 21 to make the overlapping surface 41 and the welding surface 53 reach a matching state; again, start the cylinder 31 to start the clamping unit 3, and make the pressure block 35 press and fit on the fitting surface 43 to achieve a weldable state; finally, complete the welding according to the design requirements, open the cylinder 31, take out the assembly of the box beam 5 and the bracket 4, and reach the state of waiting for inspection and storage.

[0054] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
