Specific embodiment
The specific embodiment of the battery box cover welding tooling in the utility model is illustrated now in conjunction with attached drawing.
It as shown in Figure 1 to Figure 2, is the structure of battery box cover welding tooling in the utility model, battery box cover welding tooling
Including two parts, respectively as the positioning plate of first part 1 and as the chassis body of second part, wherein chassis body
The resistance of resistance to deformation can be provided for battery box cover to be welded, and the weight of tooling can be reduced using chassis body
Amount, the support of positioning plate 1 is arranged in be supported fixation to battery box cover 4 to be welded in chassis body, because in frame master
Positioning plate 1 is provided on body, positioning plate 1 is directly contacted with battery box cover 4, and the flatness of positioning plate 1 directly determines battery
Case lid 4 is in unwelded preceding flatness, and the flatness of positioning plate 1 is easy to control when processing to positioning plate 1, if right
The chassis body that positioning plate 1 is supported can be because cause to put down the reason of welding stress or rigging error in assembly or processing
Face degree is bad, crossbeam or the one high and one low situation of stringer occurs, but chassis body directly cannot directly connect with battery box cover 4
Touching, but positioning plate 1 is supported, if positioning plate 1 is fixed in rugged chassis body, positioning plate 1 occurs
The problem of inclination, but the flatness of positioning plate 1 is unaffected, and still is able to be engaged with positioning plate 1 to be welded
The flatness of battery box cover 4.
The location hole 11 as location structure is offered on positioning plate 1, when for connected positioning plate 1 and battery box cover 4
When connector is threaded through in location hole 11, battery box cover 4 and positioning plate 1 to be welded can be realized that positioning is fixed, needed
Bright, the shape of positioning plate 1 is identical as Internal periphery (i.e. the inner cavity of battery box cover) of battery box cover 4 to be welded, works as battery
When case lid 4 is provide with and is fixed on positioning plate 1, the inner wall and the plate face location fit on positioning plate 1 of battery box cover 4, to increase
Add positioning plate 1 to the bearing area of battery box cover 4, and the Internal periphery of the shape due to positioning plate 1 and battery box cover 4 is kissed
It closes, if welding deformation does not occur in battery box cover 4, battery box cover 4 is concordant with the outer profile of positioning plate 1, when battery box cover 4 exists
When deforming after the completion of welding, necessarily occur not concordant phenomenon, therefore technical staff between battery box cover 4 and positioning plate 1
It can intuitively judge whether battery box cover 4 produces the deformation for influencing product quality.
It is provided with the location hole 11 on positioning plate 1 to be located on the edge of positioning plate 1, location hole 11 is made to be located at chassis body
Outside is increased the operating space of technical staff, and is arranged in the form of such, and positioning plate 1 and to be welded can be reduced
Stress suffered by the battery box cover 4 connect, and the position of the location hole 11 on positioning plate 1 is and the installation on battery box cover 4
Hole site is corresponding to be overlapped, and battery box cover 4 realizes the cooperation with Battery case to form complete battery case by mounting hole.It is fixed
Position hole 11 is corresponding with mounting hole, and when technical staff welds, it is fixed to be directly threaded through using connector such as positioning bolt 5
It in position hole 11 and mounting hole, can guarantee that the position of the mounting hole on battery box cover 4 is fixed during the welding process, prevent
Only deviating and causing battery box cover 4 that can not cooperate with Battery case occur in the position of mounting hole.In order to guarantee to position on positioning plate 1
The precision in hole 11, technical staff carries out aperture processing using the manufacturing process of laser cutting on positioning plate 1, to process height
The location hole 11 of precision.It is also provided with multiple lightening holes 12 on battery box cover 4 to be welded, and is cut again by laser
The mode cut, by multiple lightening holes 12, reduces the weight of positioning plate 1 come what is processed, reduces positioning plate 1 to frame
The pressure of main body.
The chassis body formed by the spaced stringer 2 of two or more spaced crossbeams 3 and two or more,
Crossbeam 3 and the mutually overlap joint of stringer 2 form the bottom as battery box cover welding tooling.Its specific structure is to use three phases
Mutually parallel crossbeam 3, each portion of the length of three crossbeams 3 is identical, wherein the one side of a longest crossbeam 3 as chassis body,
And remaining two crossbeams 3 combine the another side for forming chassis body；Meanwhile chassis body uses five stringers being parallel to each other
2, wherein there is the longer stringer 2 of three length to be arranged at intervals between crossbeam 3, and there are also the shorter stringer 2 of two length with it is upper
It states two crossbeams 3 and has cooperatively formed the closed structure that chassis body is inwardly turned back, this structure makes chassis body on the whole
One jiao is inwardly retracted, technical staff can assemble the controller of battery case using this space.
It as shown in Figure 3 to Figure 4, first will be to when technical staff is using battery box cover welding tooling in the utility model
The battery box cover 4 of welding is placed on the positioning plate 1 of welding tooling, completely attaches to battery box cover 4 and positioning plate 1, battery case
Mounting hole on lid 4 is corresponding with the location hole 11 on positioning plate 1, the outer profile of battery box cover 4 and the Internal periphery pair of positioning plate 1
Together, it is then threaded through using positioning bolt 5 in location hole 11 and mounting hole, and battery box cover 4 is fixed on positioning plate 1,
Since the flatness of positioning plate 1 is higher, it can guarantee the flatness of battery box cover 4 being fixed on positioning plate 1, even if frame master
Occur one high and one low situation on body, but the flatness of battery box cover 4 guarantees by positioning plate 1, so in frame master
Positioning plate 1 is introduced on body, compared to directly battery box cover 4 to be welded is placed into chassis body, in the utility model by
Positioning plate 1 combined with chassis body the welding tooling to be formed be able to solve welding tooling in the prior art flatness difference ask
Topic.
When the rib structure that will enhance battery box cover 4 is welded on battery box cover 4, since battery box cover 4 is determined
Position bolt 5 is pressed on positioning plate 1, and when generating welding stress, positioning plate 1 and battery box cover 4 are fixed, can resist battery case
The welding deformation of lid 4 is more uniformly stressed battery box cover 4 in all directions, ensure that the precision and plane of battery box cover 4
Degree, also ensures the precision of the mounting hole on battery box cover 4.
In other embodiments, the location structure on positioning plate may be replaced by other forms: for example using being fixed on
Bolt on positioning plate.When battery box cover is fixed on positioning plate, the bolt on positioning plate passes through the installation on battery box cover
Hole, technical staff can be used threaded fastener and positioning plate and battery box cover are fixed.
In other embodiments, can also use positioning pin be threaded through in location hole and mounting hole, and be not limited to using
Positioning bolt.
In other embodiments, the location hole on positioning plate is arranged in can not also be with the peace on battery box cover to be welded
It fills hole to correspond to, but battery box cover to be welded is fixed on by the direct connector for relying on location hole and being threaded through positioning hole
On positioning plate.
In other embodiments, the outer profile of positioning plate can not also be overlapped with the outer profile of battery box cover to be welded and set
It sets, but makes the outer profile of positioning plate greater than the outer profile of battery box cover to be welded.
In other embodiments, it can also be not provided with lightening hole on positioning plate, but directly use the complete plate of a monolith
Material.
Above-described specific embodiment, purpose of utility model, technical scheme and beneficial effects to the utility model
