Abstract
The invention discloses a brazing fixture for an aluminum plate type radiator. An adjustable supporting rod and a supporting rod are fixed on a lower fixture plate; a hinge base is fixed on the adjustable supporting rod by being clamped through a nut; one end of a pressure rod is hinged with the hinge base; the middle part of the pressure rod is hinged with an arched plate; the two ends of the arched plate are welded with a left pressure plate and a right pressure plate; and a connecting plate is fixed on the supporting rod. After being fixed and pressed, the pressure rod automatically aligns pressure through the arched plate, and uniformly transmits the pressure to the left pressure plate and the right pressure plate, so that brazing defects caused by poor local planeness of the left and right pressure plates are avoided, and therefore, a whole to-be-brazed part is uniform in stress. Brazing seam quality defects caused by seams in contact surfaces of workpieces due to insufficient local pre-tightening force are avoided. The brazing fixture for the aluminum plate type radiator disclosed by the invention is not required to press by use of a counterweight block, thereby relieving weight of a brazing tool fixture, greatly reducing heating-up time, heat-preserving time and cooling time in a brazing process as well as power consumption, reducing production cost and improving production efficiency.
Description
Technical field
The present invention relates to a kind of brazing tooling fixture, particularly relate to a kind of aluminium-plate radiator soldering fixture, belong to aluminium alloy brazing technical field.
Background technology
Aluminium-made plate type heat exchanger because its thermal resistance is little, heat exchange efficiency is high, compact conformation, volume are little, lightweight, the advantage such as strong adaptability, sturdy and durable, good economy performance, be used widely in fields such as Aero-Space, boats and ships, high-power locomotive, EMU and engineering machinery, it is dynamical system important component part, especially, in the heat radiation of high heat flux high-power electronic device, very important effect is played especially.
Aluminium-plate radiator is usually by one piece of groove substrate being processed with fluid passage, one piece of smooth flat substrate, one group of radiating fin, and the parts composition such as middle clamping a slice aluminium alloy brazing sheet, is shaped through soldering.Aluminium-plate radiator, in practical work process, should have certain structural strength and sealing.Due to the maching dimension of groove substrate, flat substrate and radiating fin and form and position tolerance, location dimension etc. very large on brazing quality impact, therefore need the assembling jig of aluminium-plate radiator soldering to ensure brazing member assembly precision.
Traditional panel radiator soldering fixture, generally be made up of the jig plate of two pieces of monoblocks, be placed in respectively above the panel radiator that assembles and, rely on bolt to tighten below, and press the balancing weight of constant weight above, thus send soldering oven to and carry out soldering.And the jig plate of monoblock to the size of part before panel radiator assembling and Geometrical Tolerance Principle very high; Once the brazing filler metal gap of local is excessive, be then easy to the situation occurring leaking or solder joint performance can not meet the demands.
Summary of the invention
Technical problem solved by the invention overcomes the deficiencies in the prior art, provide a kind of structure simple, easy to operate, in brazing process, make whole workpiece be subject to the brazing jig of even clamping force all the time.
The technical solution used in the present invention is aluminium-plate radiator brazing jig, lower press plate is fixed with adjustable pole and support bar, hinge seat fastens on adjustable pole by nut clip, depression bar one end and hinge seat hinged, hinged with cambered plate in the middle part of depression bar, cambered plate two ends welding left pressing plate and right pressing plate, connecting plate is fixed on support bar.Depression bar is after being fixed and clamped, and depression bar also evenly sends pressure to left and right pressing plate through cambered plate automatic capturing, avoids the brazing defect that left and right pressing plate brings because part plan degree is bad, makes whole brazing member uniform force.
Connecting plate is provided with screwed hole, and adjustment bolt screws out and withstands on depression bar from connecting plate screwed hole.After depression bar is fixing, by fine setting adjustment bolt, depression bar clamping degree is regulated.
The invention has the beneficial effects as follows and avoid because local pretightning force deficiency makes contact surface between workpiece have gap to cause brazing quality defect, aluminium-plate radiator brazing jig of the present invention compresses without the need to using balancing weight, alleviate the weight of brazing tooling fixture, significantly reduce the intensification in brazing process, insulation and temperature fall time, and the consumption of electric power, reduce production cost, enhance productivity.
Accompanying drawing explanation
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.
Be labeled as in figure: 1-lower press plate, 2-is adjustable pole, 3-support bar, 4-hinge seat, 5-nut, 6-depression bar, 7-cambered plate, 8-left pressing plate, the right pressing plate of 9-, 10-connecting plate, 11-adjusts screw
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Aluminium-plate radiator brazing jig, lower press plate 1 is fixed with adjustable pole 2 and support bar 3, hinge seat 4 is fixedly clamped on adjustable pole 2 by nut 5, depression bar 6 one end and hinge seat 4 hinged, hinged with cambered plate 7 in the middle part of depression bar 6, cambered plate 7 two ends welding left pressing plate 8 and right pressing plate 9, connecting plate 10 is fixed on support bar 3.Depression bar is after being fixed and clamped, and depression bar also evenly sends pressure to left and right pressing plate through cambered plate automatic capturing, avoids the brazing defect that left and right pressing plate brings because part plan degree is bad, makes whole brazing member uniform force.
Connecting plate 10 is provided with screwed hole, and adjustment screw 11 screws out from the screwed hole connecting plate 10 and withstands on depression bar 6.After depression bar is fixing, by fine setting adjustment bolt, depression bar clamping degree is regulated.
Aluminium-plate radiator brazing jig of the present invention can be avoided because local pretightning force deficiency makes contact surface between workpiece have gap to cause brazing quality defect, compress without the need to using balancing weight, alleviate the weight of brazing tooling fixture, significantly reduce the intensification in brazing process, insulation and temperature fall time, and the consumption of electric power, reduce production cost, enhance productivity.
