Description

Weld jig

Technical field

The utility model relates to a kind of weld jig, and specifically, the utility model relates to the weld jig that a kind of lithium battery is used.

Background technology

Making in the engineering at lithium ion battery, because the laser of laser machine output is fixed position, realize the welding to same weldment diverse location, is that logical clamp clamps weldment moving on workbench realized this purpose.Existing monolateral weld jig, what promptly come and go on same straight line moves, it has dual mode to operate, 1. weld a toe after, anchor clamps suspend and move, the upset toe begins mobile the welding after installing folder again.2. after having welded a toe, anchor clamps return to origin position, the upset toe begins to move welding after installing folder again.

Above-mentioned anchor clamps time out is many, and utilization rate of equipment and installations is low, and every welding is intact all to need break-off on one side, just starts work after treating to have adorned again folder, and production efficiency is low, and laser port hinders operates difficult quality guarantee.

The utility model content

The purpose of this utility model be to provide a kind of production efficiency height, easy to operate, welding quality good, can realize the weld jig of continuous welding.

The purpose of this utility model is achieved through the following technical solutions: a kind of lithium battery weld jig is provided, it comprises locating piece, cushion block, two pushing blocks, base and fixed supports, this cushion block is placed on the base, this locating piece is fixed on the cushion block, a plurality of locating slots are arranged on the locating piece, this base offers plural chute, and these two pushing blocks are stepped pane, is placed on the base also can slide along chute.

With respect to existing weld jig, both sides two pushing blocks of placement can slide along chute in the utility model weld jig, a plurality of locating slots are arranged on the locating piece, pushing block cooperates with locating piece lithium battery electric core is fixed on both sides, thereby realizes welding operation by laser output continuously, and the power on welding and the turning operation of core of weld jig can be carried out simultaneously, realize continuous welding, easy to operate, productivity ratio height and welding quality are good, have circulation continuous welding effect.

Description of drawings

Fig. 1 is the structural representation of the utility model weld jig.

The specific embodiment

As shown in Figure 1, the utility model weld jig comprises locating piece 1, cushion block 2, two pushing

blocks

31,32, base 4 and fixed support 5, this locating piece 1 is placed on the cushion block 2, and this cushion block 2 and pushing

block

31,32 are placed on the base 4, and fixed support 5 base for supporting 4 also can make whole weld jig be fixed on the workbench (figure does not show).Each parts can fit together it by methods such as fixed screw, pin, key, edges, or be processed into an integral material then by on-deformable same material or the single component processing of different materials.

This cushion block 2 is that cross section is the pane of " recessed " type, locating piece 1 is fixed on the lower concave part 22 of cushion block 2, it is a pane that is provided with a plurality of locating slots 11, these a plurality of locating slots 11 are distributed in locating piece 1 both sides, a locating slot 11 can correspondingly be put an electric core to be welded, locating piece 1 setting is higher than the upper surface 21 of cushion block 2, and locating slot 11 exposes on the upper surface 21 of cushion block 2, so that electric core pad can be fixed in the locating slot 11 of locating piece 1 when being placed on the cushion block 2.

Two pushing

blocks

31,32 are separately positioned on the both sides of locating piece 1 and cushion block 2, pushing block the 31, the 32nd, stepped pane, comprise single order square 311,321 and second order square 312,322, wherein, second order square 312,322 is positioned near the position of locating piece 1 with cushion block 2, itself and cushion block 2 are contour and be parallel to each other, but it is steady to make electric core to be welded be placed on above the two keeping parallelism, single order square 311,321 is provided with a plurality of springs 313,323, and is corresponding with the locating slot 11 on the locating piece 1 respectively.

Be respectively arranged with

elongated chute

61,62 on locating piece 1 and cushion block 2 both sides on the base 4, this

chute

61,62 is vertical with cushion block 2 with locating piece 1, and pushing

block

31,32 can slide along

chute

61,62 respectively, and is close or away from locating piece 1 and cushion block 2.

Operation principle is as follows: by fixed support 5 weld jig is fixed on the laser machine worktable, and make locating piece 1 under laser output, electric core to be welded is put on the second order square 312,322 of cushion block 2 and pushing

block

31,32, electric core negative pole point is placed in the locating slot 11 of locating piece 1,

regulate pushing block

31,32 along

chute

61,62 and promote electric core, electric core front end and locating piece 1 are close to, the rear end peaks on the spring 313,323, thereby electric core is fixed between locating piece 1 and the pushing block 31,32.Setting laser machine program by promoting moving of fixed support 5 on the workbench, makes the laser of laser output output move the welding in turn that realizes electric core clockwise or counterclockwise according to locating piece 1 edge rectangle.When welding when being positioned on one side electric core of locating piece 1, can be simultaneously to the another side that is not welding overturn, operation such as clamping.
