Detailed Description
The following detailed description of specific embodiments of the invention refers to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and explanatory of the invention and are not restrictive thereof.
A welding set and a welding test method for a welding test of an axle tube and an axle housing according to the present invention, which are convenient and fast and inexpensive, will be described with reference to the accompanying drawings.
Referring to fig. 1, the existing welding test of the axle tube and the axle housing mainly adopts the solid workpiece and the universal backing ring of the axle tube and the axle housing to test, in order to avoid wasting new axle tube and axle housing as much as possible, the waste axle tube or axle housing is usually adopted to carry out debugging or testing of electron beam welding, but when the waste axle tube or axle housing is not available, the axle tube or axle housing which is newly processed is directly adopted to carry out debugging or testing, then the welding joint is cut, sampling is carried out, and whether the penetration, the fusion width, the forming, the metallographic phase, the hardness and the like of the welding line reach an ideal state or not is checked. Because need carry out many times the trial welding, the quantity of central siphon or the axle housing body that needs the consumption is more, and experimental cost is high, and all need cut the sample to central siphon and axle housing body when welding test at every turn, and production operating efficiency is lower.
In order to improve the test and lower the production efficiency, the inventor of the present application has continuously thought to find that, in the existing welding test, referring to fig. 1, the axle tube and the axle housing need to be welded into a whole, and then the welding joint needs to be sampled, and in order to avoid that the metallographic phase at the welding seam position is affected by the processing heat generated in the cutting step in the sampling process, so as to obtain an erroneous test result, the cutting is usually performed at a position far from the welding seam. In the sampling step, the axle housing far away from the welding seam is firstly cut off to obtain a first cut-and-weld structure in fig. 2, then the axle tube far away from the welding seam is cut off to obtain a second cut-and-weld structure in fig. 3, then the two ends of the second cut-and-weld structure are milled, and finally the block cutting and finishing are carried out to obtain the inspection sample in fig. 4. Therefore, the shaft tube and the axle housing are large in size, the work load of the welding sampling step is large, the operation time is long, and the test and production efficiency is low.
In view of this, as shown in fig. 5 and 10, the present application provides a new weld assembly for testing the welding of an axle tube and an axle housing, the weld assembly 100 including an axle tube trial ring 101, an axle housing trial ring 102, and a test backing ring 103. The material of the axle tube test ring 101 is the same as that of the axle tube 200, the cross-sectional shape, the cross-sectional dimension and the wall thickness of the to-be-welded end of the axle tube test ring 101 are the same as those of the to-be-welded end of the axle tube 200, the material of the axle housing test ring 102 is the same as that of the axle housing 300, and the cross-sectional shape, the cross-sectional dimension and the wall thickness of the to-be-welded end of the axle housing test ring 102 and that of the to-be-welded end of the axle housing 300 are the same. The central siphon trial ring 101 can be sleeved on the outer peripheral wall of the axial one end of the test bushing ring 103, the axle housing trial ring 102 can be sleeved on the outer peripheral wall of the axial other end of the test bushing ring 103, and thus, the welding test is carried out by adopting the central siphon trial ring 101, the axle housing trial ring 102 and the test bushing ring 103 to simulate the welding between the central siphon 200 and the axle housing 300, and the corresponding welding debugging or test data between the central siphon 200 and the axle housing 300 can be obtained. In addition, the welding assembly 100 disclosed by the invention is adopted for welding tests, and replaces the solid workpieces of the axle tube and the axle housing in the existing welding tests, so that the loss of a large number of solid workpieces of the axle tube 200 and the axle housing 300 is reduced, the debugging and testing cost is reduced, the sampling operation is simplified, the sampling difficulty is reduced, the workload in the sampling and cutting steps is reduced, the convenience and the rapidness are realized, and the working efficiency is greatly improved.
Wherein, central siphon test ring 101 and axle housing body test ring 102 all include the tip of waiting to weld and the tip of non-welding, the tip of waiting to weld of central siphon test ring 101 and central siphon 200 waits to weld the terminal surface of tip, the machining precision of excircle and hole the same, the tip of waiting to weld of axle housing body test ring 102 waits to weld the terminal surface of tip, the machining precision of excircle and hole the same with axle housing body 300, the depth of parallelism tolerance of two respective axial end faces of central siphon test ring 101 and axle housing body test ring 102 is all not more than 0.05mm and is not less than 0 mm. The design of the axle tube test ring 101 and the axle housing test ring 102 is simple, the processing difficulty is not large, the material consumption is less, and the production cost is low. In addition, the fit tolerance between the to-be-welded end of the axle tube test ring 101 and the test bushing ring 103 and the fit tolerance between the to-be-welded end of the axle housing test ring 102 and the test bushing ring 103 are test fit tolerances, the fit tolerance between the to-be-welded end of the axle tube 200 and the universal bushing ring 400 and the fit tolerance between the to-be-welded end of the axle housing 300 and the universal bushing ring 400 are predetermined fit tolerances, and the test fit tolerances are consistent with the predetermined fit tolerances. Therefore, the accuracy of welding debugging or test data can be effectively ensured.
Alternatively, the axle tube trial 101 and axle housing trial 102 may be constant section trial. The axial lengths of the axle tube test ring 101 and the axle housing test ring 102 are not less than 10mm and not less than 50 mm. The axial length of the axle tube test ring 101 and the axle housing test ring 102 cannot be too long, so that the influence on the overall length of the assembled welding test structure is reduced; the axial length of the axle tube test ring 101 and the axle housing test ring 102 cannot be too short, so that the reasonability and the welding effect of a welding test structure are ensured.
Alternatively, the axle tube trial ring 101 and the axle housing trial ring 102 may be fixed to the axle tube 200 and the axle housing 300 by fasteners, respectively.
In some embodiments, the test liner ring 103 is split and includes a shaft tube end liner ring 1031, a middle liner ring 1033 and a axle housing body end liner ring 1032 which are sequentially arranged along the axial direction, the axial length of the middle liner ring 1033 is less than the sum of the axial lengths of the shaft tube test ring 101 and the axle housing body test ring 102, and the two axial ends of the middle liner ring 1033 can be correspondingly embedded in the ring cavities of the shaft tube test ring 101 and the axle housing body test ring 102. The axial one end of the axle tube end bushing ring 1031 can be inserted into the ring cavity of the axle tube test ring 101, the axial other end of the axle tube end bushing ring 1031 can be plugged with the axle tube 200, the axial one end of the axle housing end bushing ring 1032 can be inserted into the ring cavity of the axle housing test ring 102, and the axial other end of the axle housing end bushing ring 1032 can be plugged with the axle housing 300. Thus, after the welding step of the weld test is completed, the axle tube end liner ring 1031 and the axle housing end liner ring 1032 can be directly removed, further reducing the cutting effort. The insertion structure between the axle tube end liner ring 1031 and the axle tube 200 and the insertion structure between the axle housing end liner ring 1032 and the axle housing 300 may be various, and the application is not limited thereto.
