Abstract
Aluminium-plate radiator brazing jig, adjustable strut and supporting rod are fixed in lower press plate, hinge seat is fixedly clamped by nut on adjustable strut, compression bar one end is hinged with hinge seat, it is hinged in the middle part of compression bar with cambered plate, left pressing plate is welded at cambered plate both ends and right pressing plate, connecting plate are fixed on supporting rod.For compression bar after being fixed and clamped, compression bar sends through cambered plate automatic capturing and uniformly pressure to left and right pressing plate, avoids left and right pressing plate because of the bad brazing defect brought of part plan degree, makes entire brazing member uniform force.It avoids making brazing quality defect caused by contact surface has the gap between workpiece because of local pretightning force deficiency, the aluminium-plate radiator brazing jig of the present invention is compressed without using clump weight, alleviate the weight of brazing tooling fixture, heating, heat preservation and temperature fall time in brazing process is greatly lowered, and the consumption of electric power, production cost is reduced, improves production efficiency.
Description
Technical field
The present invention relates to a kind of brazing tooling fixture more particularly to a kind of aluminium-plate radiator soldering fixtures, belong to
Aluminium alloy brazing technical field.
Background technology
Aluminium-made plate type heat exchanger because its thermal resistance is small, heat exchange efficiency is high, it is compact-sized, small, light-weight, adaptable,
The advantages that sturdy and durable, good economy performance, in fields such as aerospace, ship, high-power locomotive, high-speed EMUs and engineering machinery
It is used widely, is dynamical system important component, especially in terms of high heat flux density high-power electronic device heat dissipation, more
It is to play very important effect.
Aluminium-plate radiator usually by one piece of slot substrate for being machined with fluid channel, one piece of smooth flat substrate, one group
Radiating fin and it is intermediate clamp the components such as a piece of aluminium alloy brazing sheet composition, it is brazed and shape.Aluminium-plate radiator exists
In practical work process, should have certain structural strength and leakproofness.Due to the machinery of slot substrate, flat substrate and radiating fin
Processing dimension and geometric tolerance, location dimension etc. influence brazing quality very big, it is therefore desirable to which aluminium-plate radiator soldering is used
Assembling jig ensure brazing member assembly precision.
Traditional panel radiator soldering fixture, is generally made of the jig plate of two pieces of monoblocks, is respectively placed in and assembles
Panel radiator above and below, tightened by bolt, and in upper face pressure constant weight clump weight, so as to be sent into
Soldering oven is brazed.And the jig plate of monoblock is very high to the size and Geometrical Tolerance Principle of part before panel radiator assembling；
Once the brazing filler metal gap of part is excessive, then it is easy to appear the situations that leakage or solder joint performance cannot be met the requirements.
Invention content
Technical problem solved by the invention be overcome the deficiencies of the prior art and provide it is a kind of it is simple in structure, easy to operate,
In brazing process, make brazing jig of the entire workpiece always by uniform clamping force.
The technical solution adopted by the present invention is aluminium-plate radiator brazing jig, and adjustable strut is fixed in lower press plate
And supporting rod, hinge seat are fixedly clamped by nut on adjustable strut, compression bar one end is hinged with hinge seat, with bending in the middle part of compression bar
Shape plate is hinged, and cambered plate both ends welding left pressing plate and right pressing plate, connecting plate are fixed on supporting rod.Compression bar after being fixed and clamped,
Compression bar sends through cambered plate automatic capturing and uniformly pressure to left and right pressing plate, avoids left and right pressing plate because of part plan degree not
The brazing defect brought well makes entire brazing member uniform force.
Connecting plate is equipped with threaded hole, and adjustment bolt is screwed out from connecting plate threaded hole and withstood on compression bar.Compression bar is fixed
Afterwards, compression bar clamping degree can be adjusted by finely tuning adjustment bolt.
The beneficial effects of the invention are as follows avoid making brazed seam caused by contact surface has the gap between workpiece because of local pretightning force deficiency
Mass defect, aluminium-plate radiator brazing jig of the invention are compressed without using clump weight, alleviate brazing tooling
The weight of fixture is greatly lowered the consumption of heating, heat preservation and temperature fall time in brazing process and electric power, reduces life
Cost is produced, improves production efficiency.
Description of the drawings
Fig. 1 is the front view of aluminium-plate radiator brazing jig of the present invention；
Fig. 2 is the 3-D view of aluminium-plate radiator brazing jig of the present invention.
In figure label for：1- lower press plates, 2- is adjustable strut, 3- supporting rods, 4- hinge seats, 5- nuts, 6- compression bars, 7- bows
Shape plate, 8- left pressing plates, 9- right pressing plates, 10- connecting plates, 11- adjusting screws
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Aluminium-plate radiator brazing jig, adjustable strut 2 and supporting rod 3 are fixed in lower press plate 1, and hinge seat 4 is logical
It crosses nut 5 to be fixedly clamped on adjustable strut 2,6 one end of compression bar is hinged with hinge seat 4, and 6 middle part of compression bar and cambered plate 7 are hinged, bow
Left pressing plate 8 is welded at 7 both ends of shape plate and right pressing plate 9, connecting plate 10 are fixed on supporting rod 3.For compression bar after being fixed and clamped, compression bar will
Pressure is through cambered plate automatic capturing and uniformly sends left and right pressing plate to, avoids left and right pressing plate and is brought because part plan degree is bad
Brazing defect, make entire brazing member uniform force.
Connecting plate 10 is equipped with threaded hole, and adjusting screw 11 screws out from the threaded hole on connecting plate 10 and withstands on compression bar 6.Pressure
After bar is fixed, compression bar clamping degree can be adjusted by finely tuning adjustment bolt.
The aluminium-plate radiator brazing jig of the present invention can make to contact between workpiece to avoid because of local pretightning force deficiency
Face, which has the gap, causes brazing quality defect, is compressed without using clump weight, alleviates the weight of brazing tooling fixture, substantially
Degree reduces the consumption of heating, heat preservation and the temperature fall time and electric power in brazing process, reduces production cost, improves production
Efficiency.
