Abstract
The utility model discloses a partition-through welding spot nondestructive detecting die in an adjustable structure, which is characterized in that a plurality of detecting units (1) are selected correspondingly according to amount of partition-through welding spots of a battery, and the detecting units (1) are fixed on a supporting angle iron (9) through bolts (10) to form the integral nondestructive detecting die. Each detecting unit (1) comprises two large probes (3), two small probes (7) and a probe protecting cover (2), wherein the two large probes (3) and the two small probes (7) are mounted on the probe protecting cover (2) so that the detecting unit (1) is formed, a large probe spring (5) is mounted on one of the large probes (3) and arranged under the probe protecting cover (2) through a large probe snap spring (4), and a small probe spring (8) is mounted at the root of one of the small probe (7) close to the probe protecting cover. Positions of the probes can be flexibly adjusted according to positions of partition-through welding spots. The partition-through welding spot nondestructive detecting die in the adjustable structure is applicable to detection of the partition-through welding spots of batteries in different specifications, is high in detecting sensitivity and low in manufacturing cost.
Description
Technical field
The utility model relates to accumulator through-wall welding point Dynamic Non-Destruction Measurement, particularly a kind of adjustable structure through-wall welding point Non-Destructive Testing mould.
Background technology
Generally use the through-wall welding technology in the lead-acid accumulator manufacture process at present, the solder joint welding effect is directly connected to the output and the quality of lead-acid accumulator, is very important qualifying point in the lead-acid accumulator production process.Spatter defectives such as lead for often occurring cold welding, cracking and puncture in process of production, many accumulators producer does not have effective way to check, minority accumulator producer adopts at the mode of the corresponding a Non-Destructive Testing mould of every money battery and checks, probe, the module of this Non-Destructive Testing mould are fixed, can't be applied to the detection of other size battery, and cost of manufacture is higher.
Summary of the invention
The purpose of this utility model is: a kind of adjustable structure through-wall welding point Non-Destructive Testing mould is provided, and a cover Non-Destructive Testing mould can be applicable to the detection of multiple battery model, strengthens the sensitivity that detects, and enhances productivity.
Technical solution of the present utility model is: according to the detection module of battery through-wall welding number of spots selection respective amount, the plurality of detection module constitutes a whole set of Non-Destructive Testing mould through being bolted to support on the angle bar; Described detection module comprises two big probes, two little probes and probe protecting cover, two big probes and two little probes are installed on the probe protecting cover and form detection module, big probe springs is installed in by big probe jump ring and is positioned at probe protecting cover below on the big probe, and little probe springs is installed in little probe root near the probe protecting cover.
Wherein, the afterbody suit insulating sleeve of big probe.
The utlity model has following advantage: two that 1, adopt to give through-wall welding to adding a constant electric current between the weldment, detect the internal resistance size of battery through-wall welding solder joint, by the variation of accurate milivoltmeter display voltage, and then judge in the production run through-wall welding point and cold welding, cracking and puncture whether occur and spatter defectives such as lead; 2, according to through-wall welding point position flexible probe location, be applicable to the detection of polytypic battery through-wall welding point; 3, little probe be that plane formula contacts to weldment, avoided the little probe of common through-wall welding solder joint the cannot-harm-detection device to mechanical damage to weldment; 4, little probe has solved the problem of common Non-Destructive Testing mould probe loose contact effectively with big to the weldment contact area, has strengthened the sensitivity that detects, has enhanced productivity; 5, simple in structure, with low cost, easy to operate, measure accurately.
