Abstract
The utility model relates to a brazing fixture and belongs to the field of brazing process devices. The brazing fixture comprises an upper cover, a lower cover, connecting rods and a cover plate. Thermal stress releasing grooves are symmetrically distributed in the upper cover and the lower cover in the length direction, sleeves are arranged on the lower cover, the connecting rods penetrate through pressing plates on the upper cover and the sleeves on the lower cover, and the connecting rods and the sleeves are fixed through plug pins. By means of the brazing fixture, thermal expansion deformation of a brazing workpiece in a high-temperature environment can not happen, and the brazing fixture can be repeatedly used, and is long in service life and low in cost.
Description
Technical field
The utility model relates to a kind of soldering jig, relates in particular to a kind of soldering jig for aluminium alloy plate fin radiator, belongs to soldering processes equipment field.
Background technology
Aluminium alloy plate fin radiator need adopt vacuum brazing, and its operating temperature is up to 1000 DEG C, and workpiece to be welded is entering before slice weldering to adopt suitable tooling fixture to be installed, to ensure that workpiece can not produce because of expanded by heating distortion in brazing process.This just requires the tooling fixture for being installed must adopt the metal material more more heat-resisting than workpiece material, now generally adopt stainless steel counterweight jig to be installed to Al alloy parts in industry, counterweight jig is to be pressed between workpiece by own wt purely, and the weight needing is very big.But the phenomenon such as even stainless steel jig, in 600 DEG C of above working environments, after Reusability, also exists jig distortion, aging, wherein due to permanent deformation, jig becomes the product that is no longer applicable to being installed, and has to carry out machine and adds and reprocess or scrap processing.Although the jig of heavy amount can ensure product percent of pass, easily distortion, service time are not long, the life-span is short, cost is high for it.
Utility model content
In order to overcome the defect existing in prior art, the utility model object be to provide a kind of lightweight, the life-span is long, cost is low and in brazing process, can ensure the indeformable soldering jig of workpiece.
To achieve these goals, the utility model is by the following technical solutions:
A kind of soldering jig, comprise upper cover, lower cover, connecting rod and cover plate, described upper cover, under cover and be provided with along its length symmetrical thermal stress release groove, under described, cover and be provided with sleeve, connecting rod through be positioned at the pressing plate that covers and be positioned under the sleeve that covers, connecting rod and sleeve are fixed by latch.
Described upper cover, lower cover adopt the square steel of stainless steel to be made.
Described connecting rod and cover plate fix by latch.
Compared with prior art, utility model possesses following advantage: simple and efficient for being installed of workpiece, compare in same solid counterweight jig, it not only can ensure that clamping quality but also weight significantly reduce, weight is only 1/5 of the required balance weight of identical workpiece, and the time that is installed is only 1/2 of counterweight jig; In addition because the slotted eye on jig possesses the effect that thermal stress discharges; compare with similar jig; in high temperature vacuum brazing process; jig of the present utility model can not produce significantly distortion; so just, can better protect soldering work piece in hot environment, can not produce thermal expansion distortion, it can be repeatedly used, the life-span is long, cost is low.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
In figure: upper cover 1, lower cover 2, sleeve 21, connecting rod 3, latch 4, thermal stress release groove 5, pressing plate 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described, but the scope that should at this point not be interpreted as theme described in the utility model only limits to following embodiment, do not departing from the above-mentioned technological thought situation of the utility model, all various amendments, replacement and changes of making according to ordinary skill knowledge and customary means, include in scope of the present utility model.
As shown in Figure 1, the utility model is a kind of soldering jig, comprise upper cover 1, lower cover 2, connecting rod 3 and cover plate 6, on described upper cover 1, lower cover 2, be provided with along its length symmetrical thermal stress release groove 5, on described lower cover 2, be provided with sleeve 21, connecting rod 3 through be positioned at the pressing plate 6 covering and be positioned under the sleeve 21 that covers, connecting rod 3 is fixed by latch 4 with sleeve 21.
Described upper cover 1, lower cover 2 adopt the square steel of stainless steel to be made.
Described connecting rod 3 fixes by latch 4 with cover plate 6.
The thermal stress release groove 5 of described jig upper cover and lower cover, can be various shape, such as round, and square ellipse, staggered bar shaped etc.
