Some rigidity cavity workpiece, for example cylinder head of motorcycle engine cylinder, cylinder body, must guarantee has tight impermeability.At present, the test machine that is used to detect this class rigidity cavity air tightness of workpiece is more, mainly contains following three kinds of patterns: 1) water vat upper suspension self-powered platform formula; 2) water injection type of external water vat, water pump and flow control system; 3) cylinder piston rod passes the pattern that water vat, worktable place the cylinder piston top.But the impermeability machines of these three kinds of patterns all exist complex structure, bulky, cost of manufacture is high, consumable accessory is many, defectives such as sealing difficulty and inconvenient maintenance.
Three, summary of the invention
At the defective that the impermeability machines of prior art exists, propose meter and make a kind of cavity air tightness of workpiece solid carbon dioxide joint-detection machine that is different from existing structure, make its compact conformation, volume is little, detection is quick, Operation and maintenance are convenient, and low cost of manufacture.
Technical solution adopted in the utility model is as follows.
A kind of cavity air tightness of workpiece solid carbon dioxide joint-detection machine, include airtight instrument, cylinder top board, upper support side plate, lower support framework, do inspection valve, sealing pressure head, sealing cylinder and detection draft tube, it is characterized in that: 1) it also has water tank lift cylinder, water tank, connection water pipe, water vat, water inspection valve, sealing cylinder tracheae and water tank lift cylinder tracheae; 2) water tank lift cylinder and sealing cylinder are fixedly mounted on cylinder top board bottom, and the piston rod of water tank lift cylinder links to each other with water tank, and water tank and water vat are with being connected cross current; 3) upper and lower of sealing cylinder has the sealing cylinder tracheae to be connected with dried inspection valve respectively, and the piston rod of sealing cylinder links to each other with the sealing pressure head, and water tank lift cylinder upper and lower has water tank lift cylinder tracheae and water inspection valve to be connected respectively; 4) airtight instrument is arranged on the cylinder top board, is connected with the sealing pressure head with detecting draft tube.
Cavity air tightness of workpiece solid carbon dioxide joint-detection machine of the present utility model, compact conformation, little, the low cost of manufacture of volume, detect the cylinder head of motorcycle engine or the impermeability of cylinder body with it, detect fast, accurately and reliably, Operation and maintenance are convenient, and the water inspection time does not have consumable accessory, need not use seal yet, economical and practical; It also is applicable to the impermeability of other rigidity cavity workpiece that detection and cylinder are similar.
Four, description of drawings
Accompanying drawing is the structural representation of the utility model cavity air tightness of workpiece solid carbon dioxide joint-detection machine.
In the drawings, the airtight instrument 2-of 1-cylinder top board 3-upper support side plate 4-lower support framework 5-water tank lift cylinder 6-water tank 7-connection water pipe 8-water vat 9-does inspection valve 10-water inspection valve 11-sealing cylinder tracheae 12-water tank lift cylinder tracheae 13-measured workpiece 14-sealing pressure head 15-sealing cylinder 16-detection draft tube
Five, embodiment
Further specify the concrete structure of the utility model cavity air tightness of workpiece solid carbon dioxide joint-detection machine and its principle of work in use below in conjunction with accompanying drawing.
A kind of cavity air tightness of workpiece solid carbon dioxide joint-detection machine includes airtight instrument 1, cylinder top board 2, upper support side plate 3, lower support framework 4, does inspection valve 9, sealing pressure head 14, sealing cylinder 15 and detects draft tube 16, it is characterized in that:
1) it also has water tank lift cylinder 5, water tank 6, connection water pipe 7, water vat 8, water inspection valve 10, sealing cylinder tracheae 11 and water tank lift cylinder tracheae 12;
2) water tank lift cylinder 5 and sealing cylinder 15 are fixedly mounted on cylinder top board 2 bottoms, and the piston rod of water tank lift cylinder 5 links to each other with water tank 6, and water tank 6 is connected water pipe 7 and is communicated with water vat 8 usefulness;
3) upper and lower of sealing cylinder 15 has sealing cylinder tracheae 11 to be connected with dried inspection valve 9 respectively, the piston rod of sealing cylinder 15 links to each other with sealing pressure head 14, and water tank lift cylinder 5 upper and lowers have water tank lift cylinder tracheae 12 to be connected with water inspection valve 10 respectively;
4) airtight instrument 1 is arranged on the cylinder top board 2, is connected with sealing pressure head 14 with detecting draft tube 16.
Its principle of work in use is as follows:
Whether good with the impermeability of doing procuratorial organ's formula detection measured workpiece earlier, whether leak gas; If the impermeability of measured workpiece is bad, gas leakage is arranged, further adopt water procuratorial organ formula to detect the concrete leakage point of determining measured workpiece again.
Make in the water vat 8 when doing inspection and be in anhydrous state, measured workpiece 13 is placed water vat 8 bottoms, pulling dried inspection valve 9 makes pressure gas source enter the top of sealing cylinder 15 by sealing cylinder tracheae 11, thereby promote cylinder piston downwards, the sealing pressure head 14 that links to each other with piston rod is descended immediately, compress and seal the volume mouth of workpiece; Press the pushbutton switch of airtight instrument 1 again, make source of the gas by detecting volume cavity inflation, the detection of draft tube 16 and 14 pairs of measured workpieces 13 of sealing pressure head, then airtight instrument 1 showed " qualified " printed words and lights green light when volume cavity had leakage; At this moment oppositely pull dried inspection valve 9 again and make pressure gas source enter the bottom of sealing cylinder 15, thereby upwards promote cylinder piston, make sealing pressure head 14 unclamp the taking-up workpiece, change above operation of another measured workpiece repetition and detect by sealing cylinder tracheae 11.If when a detected result of workpiece demonstrates " defective ", just adopt water procuratorial organ formula to search leak source so that repair.
During the water inspection, pulling water inspection valve 10 makes pressure gas source enter the bottom of water tank lift cylinder 5 by water tank lift cylinder tracheae 12, thereby upwards promoting piston makes water tank 6 rise at the bottom of the case mouth position a little more than water vat 8 with the retraction of piston rod, this moment, water tank 6 interior water flooded detected workpiece because of drop by connecting in the water pipe 7 inflow water vats 8, the pushbutton switch of pressing airtight instrument 1 subsequently makes source of the gas inflate the volume cavity of measured workpiece once more by detecting draft tube 16 and sealing pressure head 14, gas must be through the leakage point of the measured workpiece observable bubble of naked eyes of emerging, thereby finds leakage point accurately and perform mark; Oppositely pull water inspection valve 10 again, make the cylinder bottom of water tank 6 tops a little less than water vat 8, the water in the water vat 8 is in anhydrous state because of in the quick reflow tank 6 of drop in the water vat 8 at this moment, and the water inspection is finished.
