Description
Technical field
The utility model relates to a kind of fixtures of pure extension weld joint samples production, belong to soldering appliance technical field.
Background technique
The citation form of the welding point of existing test button has centering welding, overlap joint welding, T-shaped to connect with corner connection etc., weldering
The operating condition when intensity of connector and the geometry of interface, size, stress condition and welding etc. is related, compared to it
The form of its several connector, centering weld suffered tensile stress on the same axis, uniform force；Welding section is less prone to gas
Hole, crackle etc. and make joint fails, be the preferable welding point form of test button, but existing centering weld joint samples
Do not ensure that weldment completes welding under the conditions of entirely on the center in operation, operating process less standardizes, not exclusively right
The attachment moment of flexure that middle welding generates, which has Tensile Test Results, to be seriously affected.
Summary of the invention
The utility model provides a kind of production fixture of pure extension weld joint samples, it is ensured that weldment is in the work in
Under the conditions of complete welding, improve the accuracy and working efficiency of experimental result, and easy to operate, while stretching can be effectively relieved
The influence of additional bending moment in experimentation.The fixture includes: welding pedestal, positioning fixture, stove bolt, lateral screw-tightened spiral shell
Bolt and longitudinal spiral fastening bolt；Welding base upper surface is provided with the longitudinal slot and transverse groove of perforation；It is set on welding pedestal
Two rows, several columns are equipped with for fixing the positioning fixture of weldment, the positioning fixture of upper and lower two rows arrangement is along transverse groove direction pair
Claim distribution；The square groove of perforation is provided on positioning fixture；Square groove is parallel to longitudinal slot perpendicular to transverse groove；Positioning card
Tool is fixed on welding pedestal by the stove bolt at both ends；Positioning fixture center is provided with longitudinal spiral fastening bolt,
Lateral screw-tightened bolt is provided on the right side of positioning fixture；Weldment passes through lateral screw-tightened bolt and longitudinal spiral fastening
Bolt is separately fixed in the square groove of upper and lower two rows positioning fixture, between weldment there are gap be weld seam, the weldering of formation
Seam is parallel to transverse groove, is transversely to the machine direction slot.When pure extension welded specimen makes, welding pedestal is horizontally arranged, weldment is led to
It crosses lateral screw-tightened bolt and longitudinal spiral fastening bolt is separately fixed in the square groove of upper and lower two rows positioning fixture, make
Weld tabs on the same line, is inserted into upper and lower weldment center in weld seam, realizes the examination of pure shear welding point by reflow soldering process
The production of sample.
The utility model structure is simple, light-weight, easily operated, and work efficiency is high, docks after welding intact.
Detailed description of the invention
Fig. 1 is the installation diagram according to a kind of fixture of pure extension weld joint samples of the utility model embodiment production.
Fig. 2 is the main body schematic diagram of positioning fixture in Fig. 1.
Fig. 3 is that weldment and Clamp for welding assemble Local map in Fig. 1.
Fig. 4 is the partial enlarged view of weld seam in Fig. 3.
In above-mentioned figure, 1 it is welding pedestal, 2 is positioning fixture, 3 is stove bolt, 4 is lateral screw-tightened bolt, 5 is vertical
To screw-tightened bolt, 6 be weldment, 7 be weld seam, 8 transverse grooves, 9 be square groove, 10 be longitudinal slot.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing to the utility model
Specific embodiment be described in further detail.
A kind of fixture of described pure extension weld joint samples production, specifically include that welding pedestal 1, positioning fixture 2,
Stove bolt 3, lateral screw-tightened bolt 4 and longitudinal spiral fastening bolt 5.Welding 1 upper surface of pedestal is provided with the longitudinal direction of perforation
Slot 10 and transverse groove 8；Two rows are provided on welding pedestal 1, several columns are used to fix the positioning fixture 2 of weldment 6, upper and lower two
The positioning fixture 2 of row arrangement is symmetrical along 8 direction of transverse groove；The square groove 9 of perforation is provided on positioning fixture 2；It is rectangular
Slot 9 is parallel to longitudinal slot 10 perpendicular to transverse groove 8；Positioning fixture 2 is fixed on welding pedestal 1 by the stove bolt 3 at both ends
On；2 center of positioning fixture is provided with longitudinal spiral fastening bolt 5, lateral spiral is provided on the right side of positioning fixture
Fastening bolt 4；Weldment 6 passes through lateral screw-tightened bolt 4 and longitudinal spiral fastening bolt 5 is separately fixed at upper and lower two row and determines
In the square groove 9 of position fixture 2, between weldment 6 there are gap be weld seam 7, the weld seam 7 of formation is transversely to the machine direction slot 10, flat
Row is in transverse groove 8.
The experimental procedure of corresponding pure extension weld joint samples production: above-mentioned welding pedestal 1 is horizontally arranged, will be welded
Part 6 passes through lateral screw-tightened bolt 4 and longitudinal spiral fastening bolt 5 is separately fixed at the rectangular of upper and lower two rows positioning fixture 2
In slot 9, makes upper and lower 6 center of weldment on the same line, be inserted into weld tabs in weld seam 7, pure extension is realized by reflow soldering process
The production of weld joint samples.
The connector that this tests novel pure extension weld joint samples fixture production is good to moderate, solder joint when pure extension is tested
Uniform force, no attachment bending generate.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
