A kind of storage battery cast welding anchor clamps
Technical field
The present invention relates to a kind of weld jig, relate in particular to a kind of cast welding anchor clamps for the single battery welding.
Background technology
Storage battery is a kind of in the battery, and its effect is to store limited electric energy, uses in suitable place, and particularly lead acid accumulator is in field extensive uses such as generating, illumination, traffic.In internal storage battery a plurality of cells that work independently are arranged, need between a plurality of cells to finish battery group by being welded to connect one of formation; For the ease of welding, need a kind of special fixtures a plurality of cells can be fixed on a certain form, weld then.
Existing lead acid accumulator product as shown in Figure 1, have positive afflux row 02 and negative afflux row 03 on each battery cell 01, respectively have a pole 04 in positive afflux row 02 and negative afflux row's 03 a end and be used for being connected in series between adjacent two battery cells, therefore positive afflux row with bear after afflux lines up type, also need to carry out the operation that monomer connects, pole between adjacent two battery cells is welded to connect, the increase of this procedure causes the battery production cycle to lengthen, production efficiency reduces, and production cost improves.For this reason, the technical staff adopts when battery current collecting is lined up type, by several bridge structures the positive afflux row of correspondence is arranged and is connected with bearing afflux, has just realized the battery cell connection in the molding procedure.But utilize existing anchor clamps as shown in Figure 2, anchor clamps comprise base plate 05, the movable type frame of being made up of some clamping plate is installed on the base plate and can produces the clamp system that skid force tightens up movable type frame to clamping plate, be provided with the automatic reset mechanism generation repulsive force opposite with the clamp system skid force that acts on clamping plate in the movable type frame and make movable type frame reply nature; Battery cell then is positioned in the well type cavity 06 of movable type frame.Because the restriction of movable type frame, bridge structure can not pass through anchor clamps, and this has caused inconvenience to production.
Summary of the invention
Problem to be solved by this invention just provides a kind of storage battery cast welding anchor clamps, designs at the storage battery product with bridge structure, and is simple in structure, easy to use, increases work efficiency, and alleviates labor strength.
For solving the problems of the technologies described above, the following technical scheme of the present invention: a kind of storage battery cast welding anchor clamps, comprise the anchor clamps base plate, hold the clamping plate assembly that battery cell uses and be used for driving the be fixedly clamped clamp arm assembly of battery cell of clamping plate assembly, it is characterized in that: described clamping plate assembly comprises two side shields that are oppositely arranged, the end of two side shields connects by side guide, also slidely connects some middle pressing plates on the side shield; Described clamp arm assembly drives two side guide slide in opposition, middle pressing plate on two side shields is pressed on the sidepiece of corresponding battery cell respectively, pressing plate is provided with moulding inclined-plane and moulding vertical plane near an end of battery cell in the middle of described, arc transition is connected between described moulding inclined-plane and the moulding vertical plane, pressing plate is connected in series by sliding axle with the side guide at two ends in the middle of some on the described side shield, described clamp arm assembly comprises the cushion block that is fixed on the anchor clamps base plate, the cam fixture block that switching has rocking arm and driven rotation by rocking arm on the cushion block; rocking arm driving cam fixture block pushing and pressing side guide; there is roller described cam fixture block end by the pin switching; push against side guide by roller during rocking arm driving cam fixture block; the position that the corresponding roller of described side guide compresses is provided with detent; anchor clamps are under clamped condition, and the part of roller embeds in the detent.
Further, the both ends of side guide are welded with alignment pin.Make the cast welding anchor clamps more accurate with cooperating of cast welded mold, improve welding precision.
Beneficial effect of the present invention: the storage battery product that the present invention is directed to bridge structure designs, the fixed form that adopts the battery cell sidepiece to compress, do not hinder bridge structure to pass through anchor clamps, and can require according to the dress box of battery cell bridge structure is bent moulding; The present invention cooperates cast welded mold, afflux just line up in the type operation can be directly with the positive afflux row of adjacent cell monomer with bear afflux row and be connected, removed follow-up battery cell connection operation from, significantly increase work efficiency, reduce production costs.

Embodiment
With reference to Fig. 2-6, a kind of storage battery cast welding anchor clamps, comprise anchor clamps base plate 1, hold the clamping plate assembly that battery cell uses and be used for driving the be fixedly clamped clamp arm assembly of battery cell of clamping plate assembly, described clamping plate assembly comprises two side shields that are oppositely arranged 2, the end of two side shields 2 connects by side guide 4, also slidely connects some middle pressing plates 3 on the side shield 2; Described clamp arm assembly drives two side guide 4 slide in opposition, and the middle pressing plate 3 on two side shields 2 is pressed on the sidepiece of corresponding battery cell respectively.Pressing plate 3 is connected in series by sliding axle 5 with the side guide 4 at two ends in the middle of some on the side shield 2.Middle pressing plate 3 is provided with moulding inclined-plane 31 and moulding vertical plane 32 near an end of battery cells, and arc transition is connected between described moulding inclined-plane 31 and the moulding vertical plane 32.
The clamp arm assembly comprises the cushion block 6 that is fixed on the anchor clamps base plate 1, and switching has rocking arm 61 and drives the cam fixture block 62 that rotates by rocking arm 61 on the cushion block 6, rocking arm 61 driving cam fixture blocks 62 pushing and pressing side guides 4; There is roller 64 cam fixture block 62 ends by pin 63 switchings, push against side guides 4 by roller 64 during rocking arm 61 driving cam fixture blocks 62; The position that side guide 4 corresponding rollers 64 compress is provided with detent 40, and the anchor clamps assembly is under clamped condition, and the part of roller 64 embeds in the detent 40.The both ends of side guide 4 are welded with alignment pin 41, make the cast welding anchor clamps more accurate with cooperating of cast welded mold, improve welding precision.
With reference to Fig. 7, the cast welding anchor clamps are fixedly clamped battery cell, finish the casting of afflux row and bridge structure 7 at the lug of battery cell by cast welded mold, recycling thimble 9 heads into battery case 8 with whole utmost point group, in the process that utmost point group heads into, bridge structure 7 successively along moulding inclined-plane 31, the 32 crooked deformation of moulding vertical plane, as shown in Figure 8, the bridge structure good looking appearance of final molding satisfies the requirement of dress box.
