Abstract
The invention discloses a high-current detecting machine, which relates to the technical field of lead-acid storage battery detecting equipment and comprises a probing nozzle consisting of two clamp sheets, wherein the lower parts of the relative inner side surfaces of the two clamp sheets are respectively provided with a downward inclined arc-shaped groove, an upper bus of each arc-shaped groove is tangent with the upper vertical plane of the clamp sheets, the curve radius of the arc-shaped surface is 8mm to 10mm, and the clamp sheets are copper sheets. Compared with the prior art, the high-current detecting machine has the advantages that two surfaces of the probing nozzle, connected with terminals are changed into arc-shaped surfaces, during the detection, the contact area of the probing nozzle and battery terminals is increased, the contact resistance is decreased, the detection accuracy is improved, the contact resistance of the probing nozzle and the terminals is decreased, the heat generated during the detection is reduced, and the service life of the probing nozzle is prolonged.
Description
Technical field
The present invention relates to lead-acid accumulator checkout equipment manufacturing technology field, especially a kind of device for lead-acid accumulator being carried out large discharge current detection.
Background technology
Lead-acid accumulator is to assemble on the automatic assembly line.The checking of great current machine on the automatic assembly line of being installed in is that the discharge performance to the finished product accumulator detects; The quality of high-rate performance can reflect the quality of the combination property of battery, be vital one trace routine so this road detects, and the quality of equipment performance also can affect the result of detection.A kind of checking of great current machine is arranged, this checking of great current machine includes main frame and pick-up unit, described pick-up unit have by wire be connected with main frame positive and negative electrode visit mouth, described positive and negative electrode is visited mouth and is consisted of by being contained in a pair of intermediate plate of visiting on the mouth controller, the relative medial surface of a pair of described intermediate plate is the plane, and the lateral surface of every described intermediate plate is provided with gas-tpe fitting.In use there is following deficiency in this checking of great current machine: visit mouth in the terminal of clamping battery, the contact area of the terminal of copper sheet and battery is very little, so that contact resistance is very large, can have influence on measurement result, greatly reduce the detection accuracy of checking of great current machine.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of high checking of great current machine of large discharge current Detection accuracy of battery.
The technical scheme that technical solution problem of the present invention adopts is: this checking of great current machine comprises the spy mouth that is made of two intermediate plates, it is characterized in that: the bottom of the medial surface that two described intermediate plates are relative all has a downward-sloping deep-slotted chip breaker, and the vertical plane in the Up Highway UHW of described deep-slotted chip breaker and the top of described intermediate plate is tangent.
In the technical scheme of above-mentioned checking of great current machine, technical scheme can also be more specifically: the radius-of-curvature of described deep-slotted chip breaker is 8 millimeters-10 millimeters.
Further, described intermediate plate is copper sheet.
Owing to adopted technique scheme, the present invention compared with prior art, the beneficial effect that has is:
1. two faces that join with terminal visiting mouth change arcwall face into, and during detection, the contact area of visiting mouth and battery terminal has obtained increase, has reduced contact resistance, have improved the accuracy that detects.
2. reduce to visit the contact resistance of mouth and terminal, reduced the heat that produces when detecting, prolonged the serviceable life of visiting mouth.
3. improved the detection accuracy of checking of great current machine.
Description of drawings
Fig. 1 is the structural representation that the embodiment of the invention is visited mouth.
Fig. 2 is embodiment of the invention synoptic diagram.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Embodiment 1:
Checking of great current machine as shown in Figure 1 and Figure 2 includes main frame and pick-up unit, pick-up unit have by wire 2 be connected with main frame positive and negative electrode visit mouth, positive and negative electrode is visited mouth and is consisted of by being contained in a pair of intermediate plate of visiting on the mouth controller, and intermediate plate is preferably copper sheet; The bottom of the medial surface that two intermediate plates are relative all has a downward-sloping deep-slotted chip breaker 1, and the vertical plane in the Up Highway UHW of deep-slotted chip breaker 1 and the top of intermediate plate is tangent, and the radius-of-curvature of the arcwall face 1 of intermediate plate is being 8 millimeters; Every intermediate plate is connected with the spy mouth controller that is connected with the tensioning of control intermediate plate by the gas-tpe fitting 3 of lateral surface.
During work, anodal spy mouth and negative pole are visited positive terminal and the negative pole terminal that mouth is clamped respectively battery, then visit mouths by main frame with two and connect, and give battery discharge; Measure simultaneously the discharge current of battery, main frame can to the data analysis that detects, be let pass to the product of full lattice by inside; Detect the accumulator release production line that maximum discharge current does not conform to requirement if having.
Embodiment 2:
The radius-of-curvature of the arcwall face 1 of intermediate plate is being 10 millimeters, and other features are identical with embodiment 1.
Claims (3)
1. checking of great current machine, comprise the spy mouth that is consisted of by two intermediate plates, it is characterized in that: the bottom of the medial surface that two described intermediate plates are relative all has a downward-sloping deep-slotted chip breaker (1), and the vertical plane in the Up Highway UHW of described deep-slotted chip breaker (1) and the top of described intermediate plate is tangent.
2. checking of great current machine according to claim 1, it is characterized in that: the radius-of-curvature of described deep-slotted chip breaker (1) is 8 millimeters-10 millimeters.
