The two sides of the supporting box 21 in the length direction are symmetrically provided with a clapboard 22 and a fixing hole 23, and the number of the clapboard 22 on each side of the supporting box 21 is at least 2. Since the whole side surface of the supporting box body 21 is large, a part of uneven part is inevitably existed as the support, and the main side plate 13 is not flat locally and is not easy to be fixed as a whole. The welding control is facilitated by the spacer 22 as a reference.
As an embodiment, 3 partition boards 22 may be provided, and the partition boards 22 are vertically fixed on the side wall of the supporting box 21 and arranged side by side in the transverse direction. The partition plate is vertically fixed on the side wall of the supporting box body, so that a reference is provided in the vertical direction; because a plurality of baffles are transversely arranged in parallel, a reference is provided in the transverse direction, and the welding precision is improved.
In order to enhance the structural strength of the supporting box 21, a connecting cross bar can be arranged inside the supporting box 21, the connecting cross bar corresponds to the position of the partition 22, and due to the support of the connecting cross bar, the supporting box can be normally used even if the distance between the partitions 22 at two sides is not changed after being used for a period of time.

The bayonet section 32 at the other end is an inclined surface, and when the single-purpose electric appliance is used independently, the contact surface of the inclined surface and the top cover plate is larger; when the wedge block is matched, the wedge block can be matched with the inclined plane on the wedge block.
As a modification, reinforcing plates are provided on both sides of the card connecting section 31. For increasing the structural strength of the main card 3.
With reference to fig. 5 and 6, in the auxiliary welding device of the present embodiment, a wedge-shaped block 4 is added to be matched with the main clamping plate 3 for facilitating welding, and one end of the wedge-shaped block 4 is a wedge-shaped head 41 for matching with the main clamping plate 3 to compress the top cover plate.
Because main cardboard 3 is difficult for cooperating the locking completely when the lamina tecti, insert the clearance between bayonet socket section 32 and the lamina tecti through wedge head 41, can pin main cardboard 3, prevent to become flexible to can apply the packing force and reduce deformation.
The outer end of the wedge block 4 is provided with a tail body 42, and the tail body 42 is of a rectangular structure integrated with the wedge head 41. In the process of inserting the wedge-shaped head 41 into the gap, the tail body 42 needs to be continuously knocked to apply power, the tail body with the rectangular structure is more impact-resistant, and the service life is longer.
In the embodiment, the concave card 5 is used for pressing the end part of the top cover plate on the main side plate. The concave-shaped card 5 comprises a jaw 51 and a locking bolt 52, the jaw 51 is of a half-open concave-shaped structure, a threaded hole is formed in a protruding section at one end of the jaw 51, and the locking bolt 52 is matched with the threaded hole; the inner side surface of the protruding section at the other end of the clamping jaw 51 can also be set to be a convex arc surface, so that a better fixing effect is obtained. When the locking bolt 52 is screwed in, the end of the locking bolt 52 can cooperate with the protruding section at the other end of the jaw 51 to clamp the middle workpiece.
With reference to fig. 7, the method for welding the top cover plate and the main side plate of the hammer of the present embodiment uses the auxiliary welding device for welding, and includes the steps of:
step 1, welding preparation:
pre-welding the main side plate 13, and welding the rib plate 12 to the side surface of the main side plate 13; the top cover plate 11 is subjected to bending processing.
The welding method in the prior art comprises the modes of manual welding, automatic welding by a machine and the like, and deformation is inevitably caused due to welding of a single main side plate, so that after welding, the main side plate after pre-welding can be leveled and corrected, and the size precision of the main side plate is ensured. The existing bending technology can also be used for the bending processing of the top cover plate, and the description is omitted in this embodiment.
And 2, positioning by using an auxiliary welding device:
