The distance between lower positioning disk, to realize the upper positioning device of adjusting and lower determine the distance between location means.
The vertical locating device 2 includes perpendicular positioning frame fastener 2.1 and perpendicular positioning frame 2.2；It is set on the pedestal
There are at least one of movable sliding 1-c, the perpendicular positioning erection to be placed on the pedestal and can slide in the movable sliding
It is dynamic, it is realized by perpendicular positioning frame fastener 2.1 and perpendicular positioning frame is anchored on pedestal.It is specific: the perpendicular positioning frame
Bottom surface be equipped with screw rod, perpendicular positioning erection is placed on pedestal and screw rod passes through the movable sliding and perpendicular positioning frame is tight
Firmware cooperation, which is realized, is fastened on perpendicular positioning frame on pedestal, while can be real by tightening and unclamping perpendicular positioning frame fastener
The position for now adjusting perpendicular positioning frame, is then fastened on pedestal；Preferably, the perpendicular positioning frame fastener is nut.
The vertical locating device requires to be fixed on pedestal by nut and movable sliding according to the size of front side board,
Ensure that air outlet is vertical with forward and backward side plate.
Using the technical solution of the present embodiment, specifically:
Step 1: it needs to carry out school inspection to assembly-welding device before the welding of cooling wind casing.Square is hung down first and stands upright on platform
The upper surface of seat, using another right-angle side of square close to connecting shaft edge, check connecting shaft whether the upper table with pedestal
Face installation is vertical；Secondly it ventilates respectively to upper positioning device and lower positioning device, checks pneumatic pawl disk in positioning device
On upper pushing block between and lower positioning device in whether move between lower pushing block on pneumatic pawl disk consistent, and utilize vernier calliper
Ruler measure each upper pushing block moving distance and each lower pushing block moving distance it is whether consistent, it is ensured that assembly-welding device of the invention exists
It can achieve coaxial precision when assembling；Then whether vertical with pedestal upper surface with square measurement vertical locating device again, really
But Fan casing air outlet is vertical with side plate (front side board and back side panel) for cold insulation.
Step 2: it is shown in Figure 6, firstly, the front side board 9.3 of cooling wind casing is put into a group pedestal for weldering control device
On, so that the air outlet straight flange of front side board is close to vertical locating device, while carrying out gas transmission to lower positioning device, makes lower pushing block outward
It stretches and pushes transition adjusting block and lower locating piece that front side board internal diameter is carried out automatic positioning clamping.
Step 3: the top plate of cooling wind casing is inserted on group weldering control device, front side board is placed according to drawing requirement
The upper surface of, tack welding is carried out, top plate is tentatively fixed on front side board.
Step 4: being mounted on upper support plate, upper locating piece above upper positioning device, by rotating upper positioning device adjustment
Upper support plate upper surface is equal with ceiling height (specifically: by adjusting the position of fixes sleeve and location nut in connecting shaft
Set realization), then screwed in place nut ensures that positioning device is fixed, it must be noted that, upper support plate passes through on itself
The central through hole in face is set on dewclaw disk, since dewclaw disk has the presence of upper pushing block that can be limited (i.e. to upper support plate
When pneumatic pawl disk in upper positioning device has been in holosystolic state, the outside diameter that each upper pushing block is constituted is greater than upper support plate
The diameter of central through hole) to guarantee that upper support plate will not be detached from dewclaw disk under gravity；
Step 5: it is shown in Figure 7, the back side panel 9.1 of cooling wind casing is inserted on group weldering control device, outside is pressed in
The top edge of top plate, interior circular portion are pressed in support plate, are close to perpendicular positioning by adjusting the air outlet straight flange of back side panel
Device；Gas transmission is carried out to upper positioning device simultaneously, carries out pushing block back side panel internal diameter toward locating piece in overhanging promotion automatic
Positioning clamps, and confirms errorless rear progress tack welding, back side panel is tentatively fixed on top plate.
After the completion of Fan casing entirety spot welding, pneumatic pawl disk in pneumatic pawl disk and lower positioning device in positioning device in change
