Detailed Implementation

[0023] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figure 1 and Figure 6As shown, this utility model proposes a power battery arc welding fixture, including: a mounting platform 1, a support mechanism (not shown in the figure), a first side pressing device 2, a second side pressing device 3, a corner pushing device 4, a support pushing device 5, and an end support device 6. The support mechanism (not shown in the figure) protrudes from the mounting platform 1, and the location of the support mechanism (not shown in the figure) is the workpiece clamping area. The workpiece 7 to be clamped is placed on the support mechanism (not shown in the figure). The first side pressing device 2, the second side pressing device 3, the corner pushing device 4, and the support pushing device 5 are all mounted on the mounting platform 1. The first side pressing device 2, the second side pressing device 3, the corner pushing device 4, and the support pushing device 5 are all mounted on the mounting platform 1. 4 and the supporting pushing device 5 surround the supporting mechanism (not shown in the figure); the end supporting device 6 supports the corner of the triangular block 72 of the workpiece to be clamped 7 away from the corner block 73 from the side; the output end of the corner pushing device 4 presses on the bend formed at the connection between the corner block 73 and the triangular block 72 in the workpiece to be clamped; the first side pressing device 2 and the second side pressing device 3 are both used to press the extended edge block 74 of the workpiece to be clamped 7 onto the supporting mechanism (not shown in the figure); the supporting pushing device 5 supports the pointed part 71 in the workpiece to be clamped, and the supporting pushing device 5 is used to press the pointed part 71 onto the top corner of the triangular block 72 in the workpiece to be clamped from the side. When the workpiece 7 to be clamped is placed on the support mechanism (not shown in the figure), the first side pressing device 2 and the second side pressing device 3 press the extended edge block 74 onto the support mechanism (not shown in the figure) from both sides respectively; the output end of the corner pressing device 4 presses precisely at the turning point where the corner block 73 and the triangular block 72 are connected; the support pressing device 5 supports the pointed part 71 and presses it onto the apex of the triangular block 72 from the side; the end support device 6 supports the corner of the triangular block 72 away from the corner block 73 from the side, so as to achieve all-round stable clamping of the power battery workpiece.

[0025] like Figure 2 As shown, the first side-pressing device 2 includes a pressing mechanism 21, a first rotary cylinder 22, and a first positioning support 23. The rotary cylinder is mounted on the mounting platform 1. The output end of the first rotary cylinder 22 is connected to the pressing mechanism 21. The first positioning support 23 is mounted on the outer shell of the first rotary cylinder 22, and the first positioning support 23 is used for the pressing mechanism 21 to be inserted. When the first rotary cylinder 22 is activated, it drives the pressing mechanism 21 connected to its output end to rotate until the pressing block 212 in the pressing mechanism 21 cooperates with the support mechanism (not shown in the figure), pressing the extension edge block 74 of the workpiece 7 to be clamped from the side, thus completing the lateral positioning and clamping of the workpiece. At the same time, the pressing mechanism 21 can be embedded in the first positioning support 23 to ensure the stability of the structure of the first side-pressing device 2.

[0026] The pressing mechanism 21 includes a pressing seat 211 and a pressing block 212. The pressing seat 211 is connected to the output end of the first rotary cylinder 22. The pressing seat 211 can rotate relative to the outer shell of the first rotary cylinder 22. The pressing seat 211 is connected to the pressing block 212 near the extension block 74 of the workpiece to be clamped. The pressing block 212 cooperates with the support mechanism (not shown in the figure) to clamp the extension block 74 of the workpiece to be clamped. When the first rotary cylinder 22 is started, its output end drives the pressing seat 211 to rotate, moving relative to the outer shell of the first rotary cylinder 22. This causes the pressing block 212 connected to the pressing seat 211 near the extension block 74 of the workpiece to be clamped to rotate as well. The pressing block 212 cooperates with the support mechanism (not shown in the figure) to clamp the extension block 74 of the workpiece to be clamped from the side, thereby achieving lateral positioning and fixing of the workpiece to be clamped.

[0027] like Figure 4 As shown, the corner pressing device 4 includes: a first pressing cylinder 41, a sliding seat 42, a pressing arm 43, and a base 44. The first pressing cylinder 41 is mounted on the base 44, and the sliding seat 42 is mounted on the output end of the first pressing cylinder 41. The pressing arm 43 is fixed to the sliding seat 42, and the pressing arm 43 presses against the bend formed by the connection between the corner block 73 and the triangular block 72 in the workpiece 7 to be clamped. When the first pressing cylinder 41 is activated, its output end pushes the sliding seat 42 to move along the base 44, and the pressing arm 43 fixed on the sliding seat 42 moves accordingly until the pressing arm 43 accurately presses against the bend formed by the connection between the corner block 73 and the triangular block 72 in the workpiece 7 to be clamped, thereby achieving stable pressing of the end of the workpiece.

[0028] like Figure 3 As shown, the second side-pressing device 3 includes: a base 31, a second rotary cylinder 32, a second positioning support 33, and a clamping mechanism 34. The base 31 is mounted on the mounting platform 1. The second positioning support 33 is fixed on the side of the base 31 near the extension block 74 of the workpiece 7 to be clamped. The second rotary cylinder 32 is mounted on the base 31. The output end of the second rotary cylinder 32 is connected to the clamping mechanism 34. The clamping mechanism 34 cooperates with the support mechanism (not shown in the figure) to clamp the extension block 74 of the workpiece 7 to be clamped. When the second rotary cylinder 32 is started, its output end drives the clamping mechanism 34 to rotate around the base 31. The clamping mechanism 34 gradually approaches the extension block 74 of the workpiece 7 to be clamped, and finally cooperates with the support mechanism (not shown in the figure) to press the extension block 74.

[0029] The clamping mechanism 34 includes a flipping frame 341, an intermediate frame 342, and a clamping block 343. The flipping frame 341 is connected to the output end of the second rotary cylinder 32. The flipping frame 341 is fixed to one end of the L-shaped intermediate frame 342, and the clamping block 343 is mounted on the other end of the intermediate frame 342. The clamping block 343 cooperates with the support mechanism (not shown in the figure) to clamp the extension edge block 74 of the workpiece 7 to be clamped. The output end of the second rotary cylinder 32 drives the flipping frame 341 to rotate around the machine base 31. The flipping frame 341 drives the clamping block 343 to flip to the vicinity of the extension edge block 74 of the workpiece 7 to be clamped through the fixedly connected L-shaped intermediate frame 342. The clamping block 343 continues to flip and cooperates with the support mechanism (not shown in the figure), finally pressing the extension edge block 74 from the side.

[0030] like Figure 5 As shown, the supporting and pressing device 5 includes: a fixed base 51, a second pressing cylinder 52, a support platform 53, and a pressing block 54. The fixed base 51 is mounted on the mounting platform 1, and the second pressing cylinder 52 is mounted on the fixed base 51. The support platform 53 is mounted on the side of the fixed base 51 near the triangular block 72 of the workpiece 7 to be clamped. The support platform 53 is used to support the pointed part 71 of the workpiece 7 to be clamped. The output end of the second pressing cylinder 52 is connected to the pressing block 54, which is used to press the pointed part 71 of the workpiece 7 to be clamped onto the apex of the triangular block 72. When the second pressing cylinder 52 is activated, it drives the pressing block 54 to press the pointed part 71 of the workpiece 7 to be clamped onto the apex of the triangular block 72. At the same time, the support platform 53 on the side of the fixed base 51 near the triangular block 72 provides support for the pointed part 71, thereby achieving stable support and pressing of the pointed part 71.

[0031] The end support device 6 is a blocking block, which is in close contact with the side of the triangular block 72 away from the corner block 73. When the corner pressing device 4 presses the workpiece 7 to be clamped, the blocking block provides support to the end of the triangular block 72.

[0032] In this application, the first side pressing device 2, the second side pressing device 3, the corner pressing device 4, and the end support device 6 are used to position the triangular block 72, the corner block 73, and the extended edge block 74 in the workpiece 7 to be clamped. The bottom edge of the triangular block 72 is positioned by the cooperation of the first side pressing device 2, the second side pressing device 3, and the support mechanism. The corner pressing device 4 and the end support device 6 are used to position the two bottom corners of the triangular block 72, thereby stabilizing the triangular block 72. When the pointed part 71 is subsequently pressed at the top corner of the triangular block 72, the triangular block 72 is stable, thus avoiding inaccurate welding position due to the pushing of the pointed part 71. By setting the support pressing device 5, not only is the pointed part 71 positioned and supported, but the pointed part 71 is also pressed tightly at the top corner of the triangular block 72. Therefore, the first side pressing device 2, the second side pressing device 3, the corner pressing device 4, the end support device 6, and the support pressing device 5 are all far away from the point to be welded between the pointed part 71 and the triangular block 72.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
