Abstract
The invention relates to a laser welding clamp used for battery welding. The laser welding clamp comprises a base and a press block located above the base, wherein the base comprises a base board and slide tracks arranged at the two ends of the base board and fixedly vertically connected with the base board, the side faces of the press block are provided with sliding chutes adaptive with the slide tracks, the base is provided with multiple positioning holes for limiting the position of a battery, the size of the positioning holes is adaptive to the outer diameter of the battery, multiple welding holes used for battery welding are formed in the press block, and the welding holes are in one-to-one match with the positioning holes in position. According to the laser welding clamp used for battery welding disclosed by the invention, the welding process is greatly facilitated, the battery can be accurately positioned, the space between the batteries is guaranteed, and the battery is fixed and clamped in the welding process, so that the shaking and toppling of the battery are prevented and the welding efficiency is improved.
Description
Technical field
The present invention relates to a kind of weld jig used while welding battery, relate in particular to a kind of fixture used while adopting laser to carry out welding battery.
Background technology
The large multiplying power battery pack that has at present some to consist of single baby battery, when connecting, need to weld baby battery and bonding conductor between single baby battery, lacks corresponding stationary fixture during welding, and welding efficiency is low.
Summary of the invention
For solving existing weld jig, lack, the technical problem that welding efficiency is low, the invention provides a kind of fixture for laser welding.
Technical solution of the present invention is as follows:
A fixture for laser welding, its special character is: comprise base, be positioned at the briquetting of base top, described base comprises base plate, is positioned at base plate two ends and the slide rail that be connected vertical with base plate; The side of described briquetting is provided with chute; Described chute and slide rail are suitable;
On described base, be provided with that a plurality of the size of described locating hole and the external diameter of battery are suitable for limiting the locating hole of battery location, on described briquetting, be provided with a plurality of welding holes for welding battery; Described welding hole mates one by one with the position of locating hole.
Above-mentioned welding hole is straight hole, bellmouth or reverse taper hole.
Above-mentioned welding battery is aluminium alloy with the material of fixture for laser welding.
Above-mentioned chute is dovetail groove.
Above-mentioned locating hole is stepped hole or blind hole.
Beneficial effect of the present invention:
1, fixture for laser welding of the present invention greatly facilitates welding process, can accurately locate battery, guarantees the spacing between battery; And in welding process, battery is fixed to clamp, prevent rocking and toppling over of battery, improve welding efficiency.
2, the welding hole in fixture for laser welding of the present invention adopts reverse taper holes, the damage that the heat producing in the time of can alleviating laser weld on the one hand causes fixture; During on the other hand for welding, observe welding effect the good visual field is provided, be more convenient for observing the welding situation of battery.
3, the material of fixture for laser welding of the present invention adopts aluminium alloy, and with the Metal Phase ratio such as stainless steel, aluminium alloy is strong to the reflectivity of laser, can alleviate the infringement that laser causes fixture, and aluminium alloy has advantages of lightweight simultaneously.
3, chute adopts dovetail groove can guarantee that the glide direction of fixture is restricted to slide up and down, the uniformity of battery location while guaranteeing each clamping battery; And with screw thread guiding, compare, clamping action is simple, easily operation.
