Description
Technical field
The present invention relates to a kind of square or flat specimen centering welding Novel clamping apparatus, it is specially adapted to the butt welding of square metal interface, belongs to the soldering appliance technical field.
Background technology
The welding of existing test button generally adopts overlap welding, and this method of attachment is stressed unreasonable, thereby the suffered tension of sample is on same axis, thus there is shear stress on weld seam, in use may be because shear stress makes too greatly joint fails.Another kind method be adopt butt welding the cross section of two samples to well welding afterwards, existing method is put into a groove to two samples and is fixed, then welded, after being soldered, again sample is taken out, this welding method makes commissure stressed evenly, but can not guarantee the entirely on the center of two samples, operating process is standard not too, larger on the experimental result impact.These two kinds of methods all can not be accurate the Control Assay joint between distance.
Summary of the invention
The purpose of patent of the present invention is to provide a kind of square or flat specimen centering Clamp for welding, under the condition of guaranteeing sample centering, has improved operating efficiency, has improved precision, and easy and simple to handle.
Patent of the present invention is a kind of square or flat specimen centering Clamp for welding, mainly by wedge shape saddle 1, welding base 2, positioning fixture 3, fastening bolt 4, stove bolt 5, micrometer caliper 6, formed, the welding base upper surface is provided with cannelure and the transverse groove of perforation, the release of excess solder while being mainly used in welding, one side of welding base is provided with slide unit groove 8, micrometer caliper is fixed on slide unit groove 8, after micrometer caliper slides into correct position on slide unit groove 8, with the welding base, is fixed together, be fixed with the positioning fixture 3 of two rows along the transverse groove symmetry on the welding base, positioning fixture 3 is for having the fritter that connects square groove, the preferred cuboid of this fritter, square groove vertical transverse groove and be parallel to cannelure, positioning fixture 3 is fixed on welding base 1 by the stove bolt 5 at two ends, positioning fixture 3 centre bits are equipped with a fastening bolt 4, for fixing of welded specimen, have cannelure between the adjacent positioned jig on the welding base, the movable end of micrometer caliper is provided with a baffle plate 7, baffle plate 7 and a side sample close contact, when baffle plate 7 moves, sample also and then moves together, thereby the accurate accurate distance of controlling both sides sample joint.
During use, above-mentioned welding base is placed on wedge shape saddle 1; wedge shape saddle 1 makes to weld base inclination certain angle; sample relies on the face that self gravitation can be lower with positioning fixture 3 adjacent, thereby makes the sample on both sides reach centering, and positioning fixture 3 is mainly used in the preliminary fixing of sample position; 4 pairs of samples of fastening bolt are exerted pressure, and the both sides sample is fixed on welding base 2, and makes it keep centering, and in the time of welding, the position of two samples can not be moved yet.
The utlity model has following advantage: simple in structure, lightweight, easy operating, high efficiency, after welding, docking is intact.
The accompanying drawing explanation
Fig. 1 is the installation diagram of this Clamp for welding;
Fig. 2 is the side view of micrometer caliper;
Fig. 3 is the main body schematic diagram of welding base;
Fig. 4 is the main body schematic diagram of positioning fixture;
Fig. 5 is the schematic diagram of wedge shape saddle;
(1) wedge shape saddle wherein, (2) welding base, (3) positioning fixture, (4) fastening bolt, (5) stove bolt, (6) micrometer caliper, (7) baffle plate, (8) slide unit groove.
The specific embodiment
Mainly by wedge shape saddle 1, welding base 2, positioning fixture 3, fastening bolt 4, stove bolt 5, micrometer caliper 6, formed, the welding base upper surface is provided with cannelure and the transverse groove of perforation, the release of excess solder while being mainly used in welding, one side of welding base is provided with slide unit groove 8, and slide unit groove 8 is fixed with micrometer caliper, be fixed with the positioning fixture 3 of two rows and transverse groove symmetry on the welding base, positioning fixture 3 is for having the square fritter that connects square opening, square opening vertical transverse groove and be parallel to cannelure, positioning fixture 3 is fixed on welding base 1 by the stove bolt 5 at two ends, positioning fixture 3 centre bits are equipped with a fastening bolt 4, for fixing of welded specimen, have cannelure between the adjacent positioned jig on the welding base, the movable end of micrometer caliper 6 is connected with a baffle plate 7, baffle plate 7 and micrometer caliper movable end are fixed together, in the micrometer caliper bottom, it is wedge base, this base can interiorly move freely along the chute direction at the slide unit groove 8 of welding base.
Experimental procedure: first with stove bolt, positioning fixture is fixed on the welding base, then will weld base is placed on the wedge shape saddle, sample is inserted in positioning fixture, sample relies on the face that self gravitation can be lower with positioning fixture 3 adjacent, now twist micrometer caliper after bring in accurate moving stop 7, baffle plate 7 promotes a side sample mobile identical displacement simultaneously, when sample joint distance in both sides reaches setting value, tighten fastening bolt and can fix sample, after removing wedge shape saddle and micrometer caliper, coat scaling powder at the sample interface, put lastblock scolding tin, then put into reflow soldering, backflow is soldered to certain hour, take out Clamp for welding, turn on stove bolt and fastening bolt, take out the sample welded, the sample alignment degree welded is good, the accurate 0.02mm of the thickness of scolding tin, precision is much larger than the precision of general Clamp for welding, during tension test, scolding tin is stressed evenly.
