Description
Technical field
The utility model relates to a kind of welding clamp, and in particular, the utility model is the welding clamp about battery cover board.
Background technology
At present, portable electrical equipment uses in a large number, needs a large amount of batteries, and the various accessories relevant with battery also are that quantity is surprising, and is just very big as its output of battery cover board.Need welding one sheet metal as electrode on the battery cover board, match with battery electrode in the battery case, so welding precision is had relatively high expectations.Need a kind of simple to operate, efficient is high, precision is high welding clamp, to meet the needs of production for this reason.
Patent Office of the People's Republic of China has announced a CN2925755Y document on July 25th, 2007, name is called the battery cover board positioning fixture, the document discloses a kind of battery cover board positioning fixture, be specifically related to a kind of anchor clamps that are used for welding cylindrical shape battery cover board and transition metal band, it comprises fixed head and adjusts plate, cave in downwards and form first depressed area in the upper surface part subregion of described fixed head, described adjustment plate can slide in first depressed area, forms a width-adjustable between the lateral margin of the one lateral margin and adjacent first depressed area, is used to locate the groove of cover plate.Groove is the structure of width-adjustable joint, therefore the same anchor clamps location that can realize the different in width cover plate.The upper surface of fixed head can further extend a boss on one side direction of first depressed area, the vertical step surface of described boss protrudes out the upper surface of adjusting plate, and vertical with the bearing of trend of groove, thus battery unit to be welded accurately can be located, can guarantee the accurate of welding position.Its shortcoming is the welding that can not be applicable to the rectangular battery cover plate.
The utility model content
The purpose of this utility model is: the weld jig that a kind of rectangular battery cover plate and metal electrode film are provided.
The technical scheme that its technical problem that solves the utility model adopts is: be made up of upper die and lower die; The marginal position of described patrix lower surface is provided with the step of protrusion; There is a protrusion location division of staggering with the patrix step in a described counterdie upper surface one bight, and the height of location division equates with the shoulder height of patrix; Behind patrix and the counterdie matched moulds, between patrix and counterdie, surrounded a battery cover board fixed area by step and location division, the step edge and the edge, location division that surround the battery cover board fixed area are perpendicular; Patrix has a breach, and notch geometry and electrode head shape are coincide, and the position of breach is corresponding in the position of battery cover board with electrode.The effect of patrix step is exactly to determine the lengthwise position of battery cover board in weld jig, and step also can be arranged on counterdie certainly.The gap position of patrix and step have been determined the lengthwise position of electrode on battery cover board; The lateral attitude of electrode on battery cover board determined in the gap position of patrix and the location division of counterdie.
Behind patrix and the counterdie matched moulds, need the facing up of welding electrode sheet, the direction consistent to insert the battery cover board fixed area inwardly, and be close to the location division of the step and the counterdie of patrix battery cover board with electrode head.With electrode contact with battery cover board face down, the head of electrode inserts the breach of patrix inwardly.So just guaranteed that the lengthwise position of electrode on battery cover board fix.
As preferably, at the lower surface of described patrix, step is provided with the V-arrangement location prominent bar perpendicular with step.At the upper surface of described counterdie, with protrude the position of staggering the location division and have several and the patrix V-arrangement location parallel V-arrangement locating slot of bar of dashing forward.The prominent bar in V-arrangement location matches with the V-arrangement locating slot can fixed electrode and the lateral attitude of battery cover board.The prominent bar in V-arrangement location matches with different V-arrangement locating slots in the counterdie, has determined the lateral attitude of various different battery cover boards and electrode.Except locating with the V-shaped groove mode, also the mode that can adopt the hole to add alignment pin changes the relative position of upper and lower mould.
As preferably, the height of described battery cover board fixed area and the thickness of battery cover board are complementary.Because electrode is very thin, if the height of battery cover board fixed area is too big, electrode is down inserted cause dislocation easily.
As preferably, described patrix equates with the thickness of electrode or greater than the thickness of electrode at the thickness of battery cover board fixed area.So promptly be convenient to operation, also be not easy the electrode gap crossing is caused dislocation.
As preferably, the precision of each location dimension of described upper die and lower die is ± 0.2mm.
As preferably, the material of described upper die and lower die is A3 steel.
The beneficial effects of the utility model are: simple in structure, be suitable for the electrode welding of rectangular battery cover plate, and easy to operate, electrode potential is accurate, has improved production efficiency and product quality.
