Abstract

The utility model discloses a kind of expand tube head fast detecting tool, it is characterized in that comprising drift and no-go gage, the internal diameter of described drift is expand tube head maximum outside diameter+0.02mm, and described no-go gage external diameter is expand tube head maximum outside diameter-0.02mm, described drift and no-go gage external diameter are 20mm, are highly 15mm; The appearance of described drift and no-go gage is provided with a symmetrical plane vertically.The utility model testing tool can carry out the inspection of expand tube head fast, and whether qualified Direct Recognition expand tube head is, and is applicable to the expand tube head be arranged on pipe expanding equipment.

Description

A kind of expand tube head fast detecting tool
Technical field
The present invention relates to fin tube type heat exchanger processing quality control field, specifically a kind of expand tube head fast detecting tool.
Background technology
Expand tube head is the vital part of fin tube type heat exchanger expand tube processing, and whether expand tube head is qualified, directly has influence on the elasticity of heat exchanger expand tube, affects the performance of heat exchanger and even whole air conditioner (machine).
Whether heat exchanger processing industry detects the method for expand tube head, no matter is operative employee's self-inspection, or usual sampling observation, generally adopts outside micrometer as survey instrument, adopt the method measuring external diameter one by one to meet the requirements to detect expand tube head.
The milscale direct method of measurement operates not only time-consuming but also require great effort, and has a strong impact on production efficiency, and relative to operative employee, accurately can not identify that whether qualified expand tube head is.
For the expand tube head be arranged on pipe expanding equipment, because between expander roll (installing expand tube head), spacing is very little, the expand tube head milscale of middle part is difficult to measure.If pull down expand tube head to measure, the labor hour expended will be multiplied again.
In the daily production of heat exchanger, need to monitor the expand tube head validity on pipe expanding equipment, thus guarantee heat exchanger expand tube crudy.
Summary of the invention
The weak point that the present invention exists in order to avoid prior art, provides a kind of expand tube head fast detecting tool.This testing tool can carry out the inspection of expand tube head fast, and whether qualified Direct Recognition expand tube head is, and is applicable to the expand tube head be arranged on pipe expanding equipment.
Technical solution problem of the present invention adopts following technical scheme:
A kind of expand tube head fast detecting tool, its design feature is to comprise drift and no-go gage, and the internal diameter of described drift is expand tube head maximum outside diameter+0.02mm, and described no-go gage internal diameter is expand tube head maximum inner diameter-0.02mm, described drift and no-go gage external diameter are 20mm, are highly 15mm; Described drift and no-go gage are provided with the radial handle removably connected.
Design feature of the present invention is also:
Described drift and no-go gage appearance are provided with internal diameter size mark.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, detect fast, save man-hour
Before improvement, with miking, per hourly measure 120, after improving, go-no go gauge detects, and per hourly detects 720, and detection efficiency improves 6 times.On average install 80 expand tube heads by separate unit pipe expanding equipment to calculate, every platform equipment can save 33.3 minutes man-hours.
2, accurately identify, avoid erroneous judgement
Before improvement, can only measure a direction with miking at every turn, can not accurately differentiate whether qualified expand tube head is, some expand tube head do not justified possible is confirmed to be certified products.
After improvement, go-no go gauge is to the equal examinations of expand tube head surrounding, and the circularity for expand tube head also has detection effect.
Accompanying drawing explanation
Fig. 1 is drift using state schematic diagram of the present invention.
Fig. 2 is no-go gage using state schematic diagram of the present invention.
Number in the figure: 1 drift, 2 no-go gages, 3 expand tube heads, 4 expander rolls, 5 handles.
Embodiment
As shown in Figure 1, 2, expand tube head fast detecting tool, comprises drift 1 and no-go gage 2, and the internal diameter of drift 1 is expand tube head maximum outside diameter+0.02mm, and no-go gage 2 internal diameter is the most internal diameter-0.02mm of expand tube head, and drift and no-go gage external diameter are 20mm, are highly 15mm; Drift and no-go gage are provided with the radial handle 4 removably connected.
During concrete enforcement, the expand tube head specification used at present as Yang Zi air conditioner company limited is φ 6.72mm, φ 9.16mm, and expand tube head deviation range is ± 0.02mm, so the specification (internal diameter) of go-no go gauge is defined as φ 6.70, φ 9.14, φ 6.74, φ 9.18mm.
The internal diameter size deviation of go-no go gauge presses ± 0.001mm making, improves a magnitude than the precision of expand tube head.
Go-no go gauge external diameter is designed to φ 20mm, is less than expander roll 4 installing space, is convenient to measure the expand tube head be arranged on pipe expanding equipment.
Go-no go gauge height is designed to 15mm, reduces difficulty of processing and improves machining precision.Meanwhile, outside go-no go gauge, be marked with internal diameter size, be convenient to identify go-no go gauge specification.
Using method:
Go-no go gauge for Yang Zi air conditioner company limited:
1, for the expand tube head of φ 6.72mm, go-no go gauge φ 6.70 is no-go gage, and go-no go gauge φ 6.74 is drift.For the expand tube head of φ 9.16mm, go-no go gauge φ 9.14 is no-go gage, and go-no go gauge φ 9.18 is drift.
2, detect the expand tube head be arranged on pipe expanding equipment, first select suitable go-no go gauge, then load onto handle 4.Whether hand-held go-no go gauge handle, along the bottom-up mobile go-no go gauge of expand tube head, observe go-no go gauge by expand tube head.
3, go-no go gauge taken out after detecting, detect next expand tube head, defective expand tube head pulls down replacing.
