Abstract
The utility model discloses a wall-penetrating welding spot nondestructive testing mould which comprises a first polyvinyl chloride (PVC) mould board (1), a second PVC mould board (8), large probes (2) and small probes (3). The first PVC mould board (1) and the second PVC mould board (8) are fixed at interval through a bolt (7) and a nut (6). A plurality of large probes (8) and a plurality of small probes (3) are fixed on the first PVC mould board to penetrate through the second PVC mould board (8), springs (4) are sleeved on the large probes (2) and the small probes (3) between the first PVC mould board (1) and the second PVC mould board (8), and the testing mould is integrally formed. The testing mould is simple in structure, low in cost, convenient to operate, capable of effectively solving the problem that probes are poor in contact and enhancing testing flexibility, accurate in measurement and capable of greatly improving production efficiency and guaranteeing product quality.
Description
Technical field
The utility model relates to lead-acid accumulator through-wall welding point Dynamic Non-Destruction Measurement, particularly a kind of through-wall welding point Non-Destructive Testing mould.
Background technology
Lead-acid accumulator is a kind of safe, electric performance stablity, " resource recycling " energy products that can low-cost regeneration.In the production run of accumulator, utmost point group welding plays key effect to the performance of battery.If utmost point group failure welding, the stability of battery will reduce, hydraulic performance decline, makes a big impact for the quality of battery.
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 discharge performance of lead-acid accumulator.Spatter the problems such as plumbous, the effectively method of inspection of accumulator producer neither one for often occurring cold welding, cracking and puncture in the through-wall welding process.
Summary of the invention
The purpose of this utility model is: a kind of through-wall welding point Non-Destructive Testing mould is provided, and this probe that detects mould contacts with butt-welding fitting exactly, strengthens the sensitivity that detects, and accurately checks the through-wall welding effect, guarantees the product quality of battery, enhances productivity.
Technical solution of the present utility model is: it comprises a PVC template, No. two PVC templates, large probe and little probes, a PVC template and No. two PVC templates are fixed together through bolt, nut spacing distance, some large probes and some little probes are fixed on PVC template and pass the PVC template No. two, pocketed springs on large probe between PVC template and No. two PVC templates, the little probe, whole consist of detect mould.
Wherein, the tip designs of little probe becomes edge of a knife type.
During detection, with connecting line some large probes are together in series, some little probes also are together in series with connecting line, large probe is against the bus-bar top, and little probe is against the butt-welding fitting top, passes to certain electric current at large probe, by the voltage at little probe in detecting butt-welding fitting two ends, judge the through-wall welding quality.
The utlity model has following advantage:
1, little probe contacts with the butt-welding fitting knife edge type, guarantees that probe contacts with butt-welding fitting well;
2, this detection mould structure is simple, with low cost, easy to operate, has effectively solved the problem of probe loose contact, has strengthened the sensitivity that detects, and measures accurately, greatly enhances productivity, and guarantees product quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 partial enlarged drawing.
Among the figure: No. 1 PVC templates, 2 large probes, 3 little probes, 4 springs, 5 connecting lines, 6 nuts, 7 bolts, 8 No. two PVC templates.
Embodiment
As shown in Figure 1, it comprises a PVC template 1, No. two PVC templates 8, large probe 2 and little probes 3, a PVC template 1 and No. two PVC templates 8 are fixed together through bolt 7, nut 6 spacing distances, some large probes 2 and some little probes 3 are fixed on PVC template 1 and pass PVC template 8 No. two, pocketed springs 4 on large probe 2 between PVC template 1 and No. two PVC templates 8, the little probe 3, whole consist of detect mould.
Wherein, the tip designs of little probe 3 becomes edge of a knife type.
During detection, with connecting line 5 some large probes are together in series, some little probes also are together in series with connecting line, large probe 2 is against the bus-bar top, little probe 3 is against the butt-welding fitting top, pass to certain electric current at large probe 2, by the voltage at little probe 3 detection butt-welding fitting two ends, judge the through-wall welding quality.
