Description
Technical field
The invention belongs to cell art, is related to a kind of battery case weld fixture apparatus.
Background technology
Battery case can be used for loading battery, and then allow battery pack to keep fixing.The substantially box shaped knot of existing battery case
Structure, it is necessary to by original sheet material as shown in Figure 1 when production and processing, along the position of dotted line toward inner bending, formed
Box-like structure is as shown in fig. 6, include a bottom wall 61 and multiple side walls 62, the vertical distribution of side wall 62 is around bottom wall 61.
Then bonding machine is recycled to be welded and fixed the seamed edge of side wall intersection, you can to form battery case.
(notification number is for existing Chinese patent：CN105171216A, date of publication are：2015.12.23) disclose one kind pneumatically
Butt-welding machine, including workbench, the clamping device for Workpiece clamping to be fixed being provided with workbench, clamping device has two sets,
On the table, on another set of setting propulsive mechanism, under the drive of propulsive mechanism, two sets of clamping devices mutually lean on for a set of fixation
Hold together, and then clamping force is produced on workpiece so that workpiece can be clamped.
Because two adjacent walls are welded and fixed by the welding of battery case, thus need two side walls mutually contradicting conjunction
Hold together, simple extruding pushing meanss can not effectively realize fixation to battery case, it is necessary to design one in above-mentioned technical proposal
Set can automate battery case securing clamp structure.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that a kind of battery case is welded and fixed dress
Put, the technical problems to be solved by the invention are：How automatically, quickly by battery case welding fabrication.
The purpose of the present invention can be realized by following technical proposal：
A kind of battery case weld fixture apparatus, battery case are in square box shape, and battery case has the opening-like inner chamber in side, interior
Chamber is made up of bottom wall and multiple side walls being distributed in around bottom wall, and the angle between adjacent two side is corner, is welded and fixed dress
Put including workbench, it is characterised in that the first actuator and the second clamping block, the work are fixedly installed on the workbench
The first clamping block driven by the first actuator is movably set with platform, second clamping block is used to be connected to battery case inner chamber
A wherein corner for side wall, first actuator be used to driving the first clamping block be connected to battery case intracavity sidewall remaining is each
Corner；Activity is provided for the crushing block contradicted with battery outer box wall on the workbench, is provided with and is used on the workbench
Drive crushing block and then battery case side wall is resisted against the second actuator on the first clamping block and the second clamping block.
Compared with prior art, the first clamping block that activity is set can by the first actuator to be connected to battery case more
Individual corner, while match somebody with somebody the second clamping block for closing fixed setting, make clamping power of each corner by clamping block, it is so each
Corner can form stable angle so that battery case upper part bends excessive side wall and can obtain opening up into suitable position
Put.Simultaneously with the crushing block for closing outside, crushing block can coordinate the first clamping block and the second clamping block that remaining bending is inadequate
Battery case sidewall extrusion to original position.So, battery case under the interaction of crushing block and the first clamping block and the second clamping block
Side wall can keep accurately being aligned, be easy to welding of the plumb joint for seamed edge.And this structure can be disposably by institute
Some seamed edges keep accurate fixation, and plumb joint can disposably weld all seamed edges.
Further, using said structure, Fast Installation, the dismounting of battery case can be realized.Only needed electricity when installation
One of angle clamping of pond box inwall is aligned on the second clamping block, because the first clamping block position is more inner, Bu Huiying
Ring unwelded battery case and the first clamping block and the second clamping block are covered on into the inside.Hereafter, the first actuator can voluntarily drive
One clamping block contradicts with battery case inwall corner, and battery case can voluntarily be displaced to accurate location slightly, and then realize positioning
Automation.Then the second actuator driving crushing block is pressed against battery outer box wall, battery case is formed surely while adjusting structure
Fixed clamping force, complete installation and fix.After battery case welding finishes, the first clamping block divides with battery case respectively with crushing block
From battery case can freely be deviate from, so, because the miniature deformation that welding heating is formed on battery case does not interfere with battery
The abjection of box.
In above-mentioned battery case weld fixture apparatus, first clamping block and the second clamping block are vertically arranged two
For contradicting the card access surface in the adjacent two side of battery case seamed edge, the crushing block corresponds with card access surface, and on crushing block
For the contact portion with battery outer box wall and card access surface face.The structure relative with card access surface that crushing block is set can be produced
Raw relatively stable clamping force, and allow clamping force to be maintained near seamed edge, two clamping force spacing are nearer, can stablize
Seamed edge position is delivered to, and then allows the seamed edge of two side more can accurately be alignd when welding, is easy to the steady of welding
It is fixed.The structure of card access surface also allows for stablizing corner angle simultaneously so that battery case can keep stable shape.
