Specific embodiment
Below by way of attached drawing, the present invention is described in further detail with embodiment.
Referring to figs. 1 to Fig. 4 it is found that head valve annulus dry type leakage detector of the present invention, including rack 1, logistics roller-way 9, institute
Stating rack 1 includes upper plate 23, middle plate 24, bottom plate 26 (containing workpiece backing plate) and column etc., (is led on the upper plate 23 of the rack
Cross anti-lost component 14) equipped with pressure dynamics source 6 (for pressurized cylinder), the pressure dynamics source 6 it is lower by middle plate 24 respectively with air valve seal
Blocking component 13 (in inside), exhaust duct blocking component 16 (on the outside), compressor arm 15 are connected；In the rack 1 and in valve
The side edge of blocking component 13 equipped with valve block pushing component 20 (to valve blocking component carry out push realize cylinder cap into,
Exhaust valve blocks), air accumulator 10 is housed under the bottom plate 26 of the rack, which passes through leakage detecting instrument 7 and tracheae 28
It is connected respectively with the air inlet of examined cylinder cap, exhaust outlet (inlet chamber, discharge chamber), conduit closure group is housed under the bottom plate 26
Part 18 (is in institute on the bottom plate 26 and equipped with air intake duct blocking component 27 at the lower section that valve blocks pushing component 20
Examine the side of cylinder cap workpiece).
Workpiece positioning component 19 is housed under the bottom plate 26 and in the side edge of conduit blocking component 18, in the machine
Qualified product mark component 17 is housed on frame 1 and in the side edge of valve blocking component 13, examined cylinder cap qualified product is beaten
Mark.(its same side for being in upper plate 23, middle plate 24, bottom plate 26 of security protection grating 4 is housed on the side of the rack 1
Place).Equipped with guide rail limited block 11, mobile backing plate 12 and barcode scanning group in the rack 1 and in the side edge of logistics roller-way 9
Part 25 carries out barcode scanning to examined cylinder cap.It is filled on the middle plate 24 of the rack 1 and at the two sides of valve blocking component 13
There is valve to block limit assembly 21 (two pieces altogether).The valve blocking component 13, exhaust duct blocking component 16, air intake duct closure group
Part 27, conduit blocking component 18 (being referred to as blocking tooling 3), valve block pushing component 20, workpiece positioning component 19, qualified product
Mark component 17, barcode scanning component 25, pressure dynamics source 6, leakage detecting instrument 7 are electrically connected with micro computer control component 8 respectively, You Qitong
One regulation.Rejected product channel 2 is equipped in 1 lower part of rack (lower section of bottom plate).
When work, operator will need cylinder cap to be tested to be transported to the bottom plate side of rack by logistics roller-way 9, then by
It is manually sent on bottom plate (workpiece backing plate) and test fixture, workpiece positioning component 19 sets position, and micro computer control component 8 issues
Signal, pressure dynamics source (pressurized cylinder) 6 compress cylinder cap by controlling compressor arm 15, and by (including the air valve seal of closure tooling 3
Blocking component 13, exhaust duct blocking component 16, air intake duct blocking component 27, conduit blocking component 18 etc.) be respectively completed it is each into
The closure sealing movement (can realize closure by blocking cylinder control) of (row) valve, exhaust duct, air intake duct, conduit, to prepare
Test；Security protection grating 4 plays the personal safety of protection operator in compaction process.At this moment, passed through by air accumulator 10
Tracheae, which starts inflation to one chamber of air inlet of cylinder cap, to be tested, and carries out judging whether qualification by leakage detecting instrument 7 (flow-type), and
And has on micro computer control component 8 and clearly prompt.It is further continued for carrying out two chamber of air inlet, three chambers, four the chambers test of cylinder cap, inlet chamber
All after the completion of test, one chamber of exhaust, two chambers, three chambers, four chambers that equipment can automatic jump to cylinder cap are tested respectively.If any
It tests leakage situation and is then determined as rejected product, it is necessary to be sent into rejected product channel 2, equipment can be again started up, otherwise
Equipment will be unable to start, and thus effectively prevents qualified product and the mixed of rejected product is put.Air accumulator effect is that storage compression is empty
Gas guarantees the supply of whole equipment compressed air of leak tester.It can be completed at the same time inlet valve, the exhaust of cylinder cap on one device
The detection of door (spiracular annulus band)；Each cylinder cap totally 16 valves, can divide 8 times and be tested, required time about 300 seconds, 1 year can
Complete the detection of 80,000 more than one piece cylinder caps.To the detectability of significant increase finished product cylinder cap, improve working environment, reduce labor intensity,
Improve working efficiency；And which can accurately find out on cylinder cap and leaked into (row) valve.Peace is carried out to operator's personal safety
The function of full protection, and have the function of preventing qualified product and rejected product mixing.
