Specific implementation mode
Below against attached drawing, by the description of the embodiment, making further details of theory to the specific embodiment of the invention
It is bright, to help those skilled in the art to have more complete, accurate and deep reason to the inventive concept of the present invention, technical solution
Solution.
Battery pack housing includes ontology and the both sides for being welded on body interior and intermediate several be mutually parallel and spacing is equal
Supporting beam.As shown in figs 1 to 6, described to include the present invention provides a kind of battery pack housing pneumatic type spot welding built-up jig
Pedestal 5, the shaft 4 on the pedestal 5, the turntable 2 in the shaft 4, the driving shaft 4 motor 7,
Clamping device 1 and supporting rack 6.Motor 7 can be located in pedestal 5 or turntable 2, and the present embodiment is located in turntable 2.Shaft 4 and bottom
Seat 5 is fixed, and is connect with 2 bottom of turntable by cylindrical roller thrust bearing.The turntable 2 is rectangle, on the side of surface all
Equipped with clamping device.As shown in figure 3, the left and right sides claims to be laid with 4 pairs of clamping devices, and clamping rear support beam and about 2 turntable
Both sides are parallel, and the clamping device of the left and right sides corresponds to the end and the battery pack housing that compress supporting beam respectively, with the supporting beam
It corresponds.
The both sides parallel with supporting beam also are provided with the clamping device 1, are wherein set among side there are one clamping device, with
The opposite other side laid there are three clamping device along side directions.There are one be also provided in the side in three clamping devices
Centre, opposite with the clamping device among the other side, other two clamping device is symmetricly set on intermediate clamping device two
Side.
Support frame as described above 6 is located in the turntable 2, at least provided with two, is same as holding battery pack housing central section.Described turn
2 side of platform is additionally provided with console 3, and the console 3 is equipped with the switch for controlling the motor 7 and clamping device 1.
The clamping device 1 includes support column 11, cylinder 12, clamping arm 13, compact heap 14 and supporting block 15.The support
Column 11 is fixed on the turntable 2, and the cylinder 12 is located at side of the support column 11 outside the turntable 2, the cylinder
12 cylinder body upper end is hinged on 11 side of the support column, and the external part of the piston rod of the cylinder 12 is hinged on the clamping arm
13 one end, 13 other end of the clamping arm are fixed with the compact heap 14, and 11 upper end of the support column is logical with the clamping arm 13
Stud connection is crossed, it is opposite with the compact heap 14 that the supporting block 15 is fixed on 11 inner side of the support column.It clamps in this way
11 top of the support column has protrusion 111 outwardly, and the cylinder body upper end is cut with scissors by connecting plate 1 vertical to itself
It is connected on the lower end of the protrusion 111, connecting plate 2 131 vertical to itself, the connection are fixed on the clamping arm 13
2 131 end of plate is hinged to 111 upper end of the protrusion.The support beam end has location hole, consolidates on the compact heap 14
Surely have and the matched positioning pin of the location hole 141.Battery pack housing is clamped across location hole, while realizing that supporting beam is fixed
Position and Workpiece clamping.To substantially increase clamping efficiency,
Battery pack housing is clamped using supporting block 15 and compact heap 14 are opposite, the part in addition to clamping point is not by this fixture
It influences, therefore is avoided that and welder is impacted, along with the turntable 2 that can be freely rotated, therefore this fixture can protected
Facilitate welding job while demonstrate,proving Workpiece clamping.The setting of protrusion 111 and connecting plate enables the pneumatic structure of clamping device
When clamping, connecting plate 1 is perpendicular to the piston rod direction of cylinder 12, into the dead point of balance, one 121 stress side of connecting plate
To consistent with plate length direction.Same connecting plate 2 131 is also that Impact direction is consistent with plate length direction when clamping, therefore the folder
Good reliability after tight device 1 clamps, rod piece are unlikely to deform, and service life is longer.
The console 3 is equipped with special clamping switch, common clamping switch and turntable 2 and switchs, same to be located at and the branch
It supports in three clamping devices of the side of Liangping row and is electrically connected to the special clamping switch positioned at intermediate clamping device, it is remaining
All clamping devices are electrically connected to the common clamping switch, and the motor 7 is electrically connected to the switch of the turntable 2.This be because
To want the installing component that other needs weld close to battery pack housing central section, generally use locating rack loads onto installing component, then will
Locating rack carries out installation positioning, to the installing component after positioning in battery pack housing by the mounting hole in supporting beam
It is welded.But since locating rack installation at least will be close to the clamping dress among the side for being parallel to supporting beam, the side
It sets 1 needs temporarily to open in welding, in order to ensure that battery pack housing still keeps clamping equilibrium state at this moment, needs opening
1 both sides of clamping device be symmetrical arranged two clamping devices 1.It could be facilitated by console 3 in this way and realize corresponding clamping device 1
Folding control.
It includes the L-type support 61 being fixed on the turntable 2, the T shapes being fixed in the L-type support 61 to state supporting rack 6
Support plate 62 and the L-type jacking block 63 for being fixed on the 62 top both ends of T shapes support plate, between the perpendicular plate face of the L-type support 61
It is connected by triangle reinforcing rib.
The course of work of this fixture is：Battery pack housing is placed on the fixture first, enables battery pack housing surrounding position
In in supporting block 15, middle part is supported the support of frame 6.Then four supporting beams are placed in installation site, start special clamping switch
It is with common clamping switch that supporting beam and battery pack housing locating clip is tight.Then supporting beam is welded with welder, is welded
Termination process starts 4 revolving-turret 2 of shaft to facilitate welding as needed.Supporting beam closes special clamping switch after welding,
Clamping tool on the position for needing to install locating rack is unclamped, locating rack is temporarily installed to the corresponding positions of battery pack housing
It sets, then the installing component on locating rack is welded by welder.Locating rack is detached with the installing component after welding,
Unload locating rack, so that it may to close common clamping switch, allow remaining all clamping devices 1 to unclamp, unload and complete welding processing
Battery pack housing.
This fixture substantially increases clamping efficiency, and clamped one time can realize all supporting beams and weld, and solve
The technical issues of prior art, production efficiency is high, clamping error is small, the position accurate positioning of supporting beam, good to ensure that
Product qualification rate.
