Feeder line machining accuracy is not enough.It is mainly manifested in and is overlapping end face injustice and mounting hole site not just, the subject matter brought is that increase is taken
The stress of junction, connecting bolt is easily caused when load is larger and loosens to cause the generation of short circuit accident.Due to feeder line shape
Shape is complicated, is difficult detection.The existing method that end face is detected by horizontal stand, it is laborious to take and hole position precision is judged not
Foot.To solve the above problems, it is necessary to develop some simple frocks, it is ensured that feeder line in its natural state, faying surface contraposition it is smooth,
Hole position meets tolerance.
The content of the invention
The purpose of this utility model is to provide a kind of detecting tool of middle pressure ring main unit feeder line, solves existing feeder line processing
Accuracy detection problem.
To solve the above problems, a kind of technical scheme of the detecting tool of middle pressure ring main unit feeder line of the utility model is：One
The detecting tool of ring main unit feeder line, including base, upper terminals and lower terminals are pressed in kind, it is characterised in that：Lower terminals water
Divide equally and be furnished with A phases lower end positioning hole, B phases lower end positioning hole, C phases lower end positioning hole, upper terminals vertical distribution has A phases upper end to determine
Position hole, B phases upper end positioning hole, C phases upper end positioning hole；Base, upper terminals and lower terminals material are stainless steel.
A kind of detecting tool of middle pressure ring main unit feeder line is using the stainless steel materials of 3 millimeters thicks by laser cutting and laser
Welding procedure is processed.
A kind of application method of the detecting tool of middle pressure ring main unit feeder line：1st, first by the fixing hole of terminals under feeder line with
The positioning hole alignment of lower terminals, blending bolt positioning；2nd, the fixing hole of terminals on feeder line is moved to determining for upper terminals
Position hole site, measures hole position deviation；3rd, terminals and the upper wiring end face gap width of frock on feeder line are measured with feeler gauge；4th, it is empty
Position deviation and end clearance value are in control error range, then qualified；5th, underproof feeder line is retracted into correction, then again
Detection.
In order to ensure measurement accuracy, stainless steel materials thickness is 2.98-3.00 millimeters, and Precision of Laser Cutting is controlled 0.15
In millimeter, depth of fusion 1.0-1.5 millimeters during laser welding.Feeder line hole position deviation is less than 1 millimeter, and wiring end face gap width is small
In 1 millimeter.
Using the beneficial effects of the utility model of above-mentioned measure：1st, the accuracy of detection of feeder line is improved, uniformity is good.2、
This tool structure is simple, efficient, compared with existing detection method, reduces debugging process repeatedly, can save more than 50% work
When.
