On the basis of the above embodiment, further, with reference to fig. 2, each mounting plate forms one fixed unit with two pressure plates thereon. Two groups of opposite fixing units can be arranged on the bracket component at intervals. Namely, the bracket component is connected with two groups of fixing units, and the pressing plates 4 of the two groups of fixing units are arranged oppositely. The two groups of fixing units can clamp and fix the workpiece at two ends of the workpiece, so that the positioning accuracy is improved. And the both ends of battery module are connected with the end plate respectively, and the both sides of module all need the welding curb plate, and every curb plate all needs the welding in both ends and end plate department of meeting. I.e. there are four welding positions on both sides of the module. Two sets of fixing units are provided, i.e. four press plates 4 can be pressed and positioned at four welding positions simultaneously.

On the basis of the above embodiment, further, referring to fig. 3, the fixing unit is connected with the bracket assembly in a position adjustable manner along the second direction. I.e. the mounting plate 3 is adapted for position adjustable connection with the carriage assembly in the second direction. The second direction may be a direction perpendicular to the first direction. The fixing unit is position-adjustable in the second direction, and the pressing plate 4 is position-adjustable in the first direction with respect to the mounting plate 3. Therefore, the position of the pressing plate 4 relative to the workpiece can be adjusted in two directions, the tool can adapt to more workpieces with different sizes, and the applicability and the flexibility of the tool are improved.

That is, referring to fig. 3, the side of the pressing block 6 away from the pressing plate 4 shields a part of the space of the positioning groove 12, so that the space of the positioning groove 12 is further limited under the shielding of the pressing block 6. Can set up one side that briquetting 6 kept away from clamp plate 4 and press close to the welding seam position to when clamp plate 4 compresses tightly the work piece, briquetting 6 is pressed close to the welding seam position and is supported and press on the work piece, is favorable to improving welding position's accuracy. The width of the positioning slot 12 may be wider than the width of the weld location. So that the welding head can be easily inserted into the wide positioning groove 12 and the precise welding is performed in the limit of the pressure piece 6.

The pressing block 6 is arranged along the length direction of the positioning groove 12. Namely, the pressing block 6 is arranged along the positioning groove 12. And the width of the side of the pressing block 6 connected with the pressing plate 4 is less than or equal to the width of the side of the pressing block 6 far away from the pressing plate 4. Referring to fig. 6, the width is the width of the pressing block 6 in the second direction. The pressing block 6 is arranged to be larger in width away from one side of the pressing plate 4, so that welding accuracy is improved by pressing close to a welding line, the contact area of the pressing block and a workpiece can be increased, and stable pressing is achieved. The width of the side, connected with the pressure plate 4, of the pressure block 6 is smaller, so that smooth insertion of a welding head is facilitated. Preferably, the side of the pressing block 6 connected with the pressing plate 4 is located at the side of the positioning groove 12. I.e. the side does not extend into the positioning slot 12 and does not shield the space of the positioning slot 12, which facilitates the insertion of the welding head.
