[0043] In order to solve the problem in the prior art that the charging pile shell is prone to tilt during welding, resulting in dimensional deviation and affecting the subsequent assembly of components, the utility model provides a clamping device for welding the charging pile shell, comprising: a main base 2, on which a guide groove 24 is provided;

[0044] A first clamp, the first clamp being capable of limiting the position of the shell to be welded in the vertical direction;

[0045] A second clamp, the second clamp can limit the shell to be welded in the horizontal direction;

[0046] A rod-shaped fixing member 3, the rod-shaped fixing member 3 is used to fix the first clamp; and

[0047] A tower-shaped fixing member 10, the tower-shaped fixing member 10 is used to fix the second clamp;

[0048] The rod-shaped fixing member 3 and the tower-shaped fixing member 10 are arranged on the main base 2 and can move in the guide groove 24 .

[0049] like Figure 1As shown, the main base 2 can be a rectangular plate, and the distribution range of the guide groove 24 on the main base 2 needs to be larger than the surface area of ​​the shell to be welded. The guide groove 24 is set to be able to move the rod-shaped fixing member and the tower-shaped fixing member from the edge of the main base 2 to the fixture fixing point on the main base 2 set according to the shape of the frame of the shell to be welded, that is, the trajectory of the guide groove 24 can be arbitrarily set according to the situation to correspond to the frame of the shell to be welded. Preferably, the guide groove 24 can be divided into two groups perpendicular to each other, and the guide grooves 24 in each group are parallel to each other. The first clamp can be set at the upper end of the side of the shell to be welded to fix it from top to bottom in the vertical direction, and the first clamp can be a clamping rod. The second clamp can be fitted outside the side of the shell to be welded to fix it in the horizontal direction, and the second clamp can be a strip clamp, an L-shaped clamp, or a pointed cone clamp. The height of the rod-shaped fixing member 3 needs to be higher than the height of the shell to be welded, and the height of the tower-shaped fixing member 10 needs to be lower than the height of the shell to be welded. The rod-shaped fixing member 3 and the tower-shaped fixing member 10 are detachably arranged on the main base 2 , for example, by snap-fitting or screw-fitting.

[0050] The charging pile shell welding is generally to weld the remaining five surfaces except the charging pile cabinet door, so the charging pile shell is usually placed flat with the opening facing upward. Figure 1 , 9 -10, the tower-shaped fixing member 10 can be arranged at the junction of two adjacent side surfaces of the shell, that is, there are at least 8 tower-shaped fixing members 10, and the remaining positions on the side of the shell can also be set separately as needed; the rod-shaped fixing member 3 can be arranged inside the side surface or outside the side surface, and the number of the rod-shaped fixing members 3 can be set arbitrarily according to the size of the shell.

[0051] Through the above technical scheme, the clamping device of the utility model that facilitates the welding of the charging pile shell is mainly used to fix various types of clamps that clamp the charging pile shell. The fixing of the clamp is achieved by setting a general base 2 and setting a rod-shaped fixing member 3 that can fix the first clamp and a tower-shaped fixing member 10 that can fix the second clamp thereon. By providing a guide groove 24, the rod-shaped fixing member 3 and the tower-shaped fixing member 10 can be further moved on the general base 2 to match charging pile shells of different sizes. Since the first clamp can limit the shell to be welded in the vertical direction, and the second clamp can limit the shell to be welded in the horizontal direction, the two opposite sides of the shell can be perpendicular to the general base, that is, the two opposite sides can be arranged parallel to each other. The clamping device has a simple structure, greatly improves the welding accuracy of the shell, and is suitable for shells of different sizes.

[0052] In some embodiments, the tower fixture 10 includes a tower fixture base and a fixture mounting block 9 disposed on the tower fixture base. Figure 5 , 9As shown, the tower-shaped fixing member base can slide and be fixed in the guide groove 24 , and a clamp mounting block 9 can also be provided on the upper surface of the tower-shaped fixing member base. The tower-shaped fixing member base and the clamp mounting block 9 are connected and clamped by a clamping screw 8 .

[0053] In some embodiments, the fixture mounting block 9 is provided with a slot for mounting a second fixture. Figure 5 As shown, each side of the fixture mounting block 9 may be provided with a groove to partially accommodate the second fixture and be connected and fixed to the second fixture, and the shape of the groove may be consistent with the shape of the portion of the second fixture embedded in the fixture mounting block 9 .

[0054] In some embodiments, the rod-shaped fixture 3 includes a rod-shaped fixture base, a mounting rod 22 disposed on the rod-shaped fixture base, and a clamp mounting arm 18 connected to the mounting rod 22 .

[0055] like Figure 4 , 10 As shown, the rod-shaped fixing member base can slide and be fixed in the guide groove 24, and the upper surface of the rod-shaped fixing member base can be provided with a mounting rod 22 and a clamp mounting arm 18 connected to the mounting rod 22. The upper surface of the rod-shaped fixing member base can be provided with a threaded hole to connect the mounting rod 22, and the mounting rod 22 can be vertically extended to a height greater than the side wall of the shell to be welded so as to set the first clamp above the side wall, and the clamp mounting arm 18 can be sleeved on the upper end of the mounting rod 22 and extend in the horizontal direction, and a clamping nut 6 can be provided between the rod-shaped fixing member base and the mounting rod 22 to adjust the clamping force.

[0056] like Figure 8 As shown, the clamp mounting arm 18 may include a horizontally extending first mounting arm 19 sleeved on the upper end of the mounting rod 22 and rotatably connected to the mounting rod 22, and a second mounting arm 20 rotatably connected to the first mounting arm 19.

The end of the second mounting arm 20 away from the first mounting arm 19 is a vertically extending sleeve with a threaded surface inside for connecting with the first clamp. The first clamp may be a clamping screw 21.

[0057] In some embodiments, the mounting rod 22 is configured to be retractable. Figure 4 , 6 As shown in FIG. 10 , the mounting rod 22 can be a telescopic rod to meet the requirements of different heights of the shells to be welded, one end of which is screwed to the base of the rod-shaped fixing member, and the other end is sleeved with a clamp mounting arm 18. The telescopic rod can be set to at least two stages of telescoping, and the length of each section can preferably be 200 mm.

[0058] In some embodiments, a plurality of limit blocks 25 are arranged at equal intervals on the main base 2. The limit blocks 25 are T-shaped blocks including an upper part and a lower part. The gaps between adjacent limit blocks 25 form guide grooves 24 so that the guide grooves 24 are distributed in a grid shape on the main base 2.

[0059] like Figure 1-3 As shown, the guide groove 24 is composed of gaps between a plurality of T-shaped limit blocks 25, and each limit block 25 has the same structure, that is, the guide groove 24 is correspondingly formed into a track gap that is narrow at the top and wide at the bottom. The guide groove 24 is arranged in a grid shape so that each section of the gap therein can be connected to each other, and it is convenient for the rod-shaped fixing member 3 and the tower-shaped fixing member 10 to move in the guide groove 24. In some specific embodiments, the total base 2 is arranged to be 2680 mm long and 1680 mm wide, the upper width of the guide groove 24 is arranged to be 50 mm, the lower width is arranged to be 80 mm, the spacing of the limit blocks 25 in the length direction is arranged to be 250 mm, and the spacing of the limit blocks 25 in the width direction is arranged to be 225 mm.

[0060] In some embodiments, the rod-shaped fixing member 3 includes a rod-shaped fixing member base, the rod-shaped fixing member base includes a first base 4, a first support column 27 arranged on the first base 4 and a first pressure plate 5 arranged on the first support column 27, and the upper part of the limit block 25 can be fixed between the first base 4 and the first pressure plate 5; the tower-shaped fixing member 10 includes a tower-shaped fixing member base, the tower-shaped fixing member base includes a second base 11, a second support column 28 arranged on the second base 11 and a second pressure plate 12 arranged on the second support column 28, and the upper part of the limit block 25 can be fixed between the second base 11 and the second pressure plate 12.

[0061] like Figure 4-5 As shown in FIGS. 9-10 , the cross-sectional area of ​​the first support column 27 can be smaller than the cross-sectional area of ​​the first base 4 and the first pressing plate 5. The rod-shaped fixing member 3 can be fixed on the guide groove 24 by clamping the upper edge of the limit block 25 between the first pressing plate 5 and the first base 4, and the first pressing plate 5 and the first base 4 can be clamped by screwing the clamping nut 6. The cross-sectional area of ​​the second support column 28 can be smaller than the cross-sectional area of ​​the second base 11 and the second pressing plate 12. The rod-shaped fixing member 3 can be fixed on the guide groove 24 by clamping the upper edge of the limit block 25 between the second pressing plate 12 and the second base 11, and the second pressing plate 12 and the second base 11 can be clamped by screwing the clamping screw 8.

[0062] In some embodiments, a ball seat 7 is embedded in the first base 4 and the first pressure plate 5 to reduce the friction between the rod-shaped fixing base and the limit block 25; a ball seat 7 is embedded in the second base 11 and the second pressure plate 12 to reduce the friction between the tower-shaped fixing base and the limit block 25.

[0063] like Figure 4-5 As shown in Figures 1 and 2, the ball seat 7 can be configured as a block formed by splicing a ball seat body 13 and a ball seat patch 17. A plurality of balls 14 are embedded in the ball seat body 13. Each ball 14 is arranged on a mounting plate 15. The lower end of the mounting plate 15 is elastically supported by a spring 16. The ball seat 7 can be arranged on the surfaces opposite to the first base 4 and the first pressing plate 5, and on the surfaces opposite to each other of the second base 11 and the second pressing plate 12. The ball seat 7 can be arranged on each edge of each surface. The ball seat 7 can mainly make the fixing part smoother when moving along the guide groove 24, and reduce the friction between the fixing part and the total base 2. When the ball 14 is subjected to a large pressure, the spring 16 is compressed. When the ball 14 is flush with the surfaces opposite to each other of the first base 4 and the first pressing plate 5, and the second base 11 and the second pressing plate 12, the fixing part is fixed on the guide groove 24.

[0064] In some embodiments, the main base 2 is surrounded by baffles 1, and blocks 23 are provided between adjacent baffles 1 to be detachably connected to the main base 2. Figure 2 As shown, at least one stopper 23 can be provided on each side of the main base 2. The stopper 23 can be integrally formed with the main base 2 or can be a separate structure. When the baffle 1 is fixed to the main base 2, the main base 2, the stopper 23 and the baffle 1 can be connected by bolts.

[0065] In some embodiments, in the vertical direction, the adjustable height of the rod-shaped fixing member 3 is greater than 200 mm, and the adjustable height of the tower-shaped fixing member 10 is less than or equal to 200 mm.

[0066] like Figure 1 As shown, the fixing position of the first clamp is higher than the fixing position of the second clamp in the vertical direction. Therefore, it is generally set that the height of the rod-shaped fixing member 3 needs to be higher than the height of the shell to be welded, and the height of the tower-shaped fixing member 10 needs to be lower than the height of the shell to be welded. Specifically, combined with the actual size of the shell to be welded, the adjustable height of the rod-shaped fixing member 3 can be greater than 200 mm, and the adjustable height of the tower-shaped fixing member 10 can be less than or equal to 200 mm.
