Abstract
The invention provides a barrel weld joint leak detector for a compressor. The barrel weld joint leak detector comprises a support which is provided with an upper arm and a test base. The barrel weld joint leak detector is characterized in that the upper arm is provided with a pressing air cylinder, the end of a plunger of the pressing air cylinder is provided with a rubber compression block, the test base is provided with a lower seal base, the center of the lower seal base is provided with a test air passage, the end face of the lower seal base is provided with a seal groove, and an O-shaped seal ring is arranged in the seal groove. According to the barrel weld joint leak detector, compressed air of two ways is used, the compressed air of a first way is used as power to drive the rubber compression block to be matched and compressed with the O-shaped seal ring so that seal space can be formed at the two ends of a pipe orifice of a welded accessory; the compressed air of a second way is used as detecting gas and filled inside the seal space, a user can directly observe whether weld joints leak, and testing is fast and low in price. The whole detection process is easy, convenient and fast, only the cheap compressed air is consumed, and the barrel weld joint leak detector is suitable for detecting barrels one by one in a bulk mode.
Description
Technical field
The present invention is a kind of instrument that detects refrigerator, air conditioner compressed machine drum body weldquality, specifically, is a kind of compressor cylindrical shell weld seam leak detector.
Background technology
Refrigerator, air conditioner compressed machine drum body are welded with inlet tube mouth usually, and the detection method of butt welded seam quality generally has two kinds after the welding.The first is to use helium to detect, and this mode needs mass spectrometer to carry out the detection of amount of leakage, and the helium of consumes expensive is not suitable for the one by one detection of part in enormous quantities.The second is part to be immersed tank detect, look into and see if there is bubble and overflow immersing tank after the complete machine sealing, single cylinder part is not welded loam cake and lower cover owing to two ends, be difficult to realize sealing detection, and need whole oven dry to do antirust processing after detecting, so method also is not suitable for doing the detection of cylinder part.
Summary of the invention
For the defective that prior art exists, the present invention proposes a kind of compressor cylindrical shell weld seam leak detector, can be fast and the impermeability of testing at an easy rate weld seam.
Technical scheme of the present invention is: a kind of compressor cylindrical shell weld seam leak detector, comprise support, support is provided with upper arm and test bench, it is characterized in that: upper arm is equipped with the cylinder of exerting pressure, the exert pressure plunger termination of cylinder is provided with the rubber compact heap, and test bench is provided with bottom sealing socket, and the bottom sealing socket center is testing air passage, the end face of bottom sealing socket is provided with seal groove, and seal groove is built-in with the O RunddichtringO.
The present invention uses two-way pressurized air, and first via pressurized air drives the rubber compact heap and cooperates compression with O type circle as power, and making the accessory in the welding is that mouth of pipe two ends form seal cavity; The the second road pressurized air is as detecting with in the gas inject seal cavity, and whether directly observe weld seam has leakage, and test is quick and cheap.

Embodiment
Be described in further detail below in conjunction with embodiments of the invention and accompanying drawing thereof.
See a kind of compressor cylindrical shell weld seam leak detector shown in the drawings, support is provided with upper arm 2 and test bench 6, and upper arm 2 is equipped with the cylinder 1 of exerting pressure, and the plunger termination of the cylinder 1 of exerting pressure is provided with rubber compact heap 3.Test bench 6 is provided with bottom sealing socket 5, and bottom sealing socket 5 centers are testing air passage 9, and the end face of bottom sealing socket 5 is provided with seal groove 7, and seal groove 7 is built-in with O RunddichtringO 8.
The end face that bottom sealing socket 5 is provided with seal groove 7 is and the Cylinder Surface of tested cylindrical shell 4 inside surface same radius, sees Fig. 2 and Fig. 3, and bottom sealing socket vertically (being the Y of tested cylindrical shell 4) sectional view shows that end face projection line 11 is straight line; Fig. 4, Fig. 5 are the bottom sealing socket transverse cross-sectional view, show that end face projection line 11 is circular arc line, and radius R is identical with tested cylindrical shell 4 inside surface radiuses, and the end face of tested cylindrical shell 4 inside surfaces and bottom sealing socket 5 can fit like a glove when test, guarantees that sealing effectiveness is good.The collar wall of the seal groove 7 of bottom sealing socket 5 has a leaning angle ɑ, and getting leaning angle ɑ is that 5 degree are better, and it is the space that has distortion to tie up when guaranteeing O RunddichtringO 8 pressurized that leaning angle ɑ is set.
Compressor cylindrical shell 4 to be measured is put to test bench 6, confirmed that the tested mouth of pipe 10 weld seams of cylindrical shell 4 enter in the scope of O type circle, cylindrical shell 4 inside surfaces compress the end face that O type circle 8 is pressed close to bottom sealing socket 5.Open the air inlet switch (not shown) of the cylinder 1 of exerting pressure, first via pressurized air enters the cylinder 1 of exerting pressure, and plunger end head drive rubber compact heap 3 is pressed among the figure mobile shown in the arrow F downwards, is pressed on the tested mouth of pipe, cylindrical shell 4 compresses O type circle 8, and the tested mouth of pipe and bottom sealing socket 5 form seal cavity.Open sealing detection air intake opening switch (not shown), the testing air passage 9 from bottom sealing socket 5 enters in the tested mouth of pipe and the bottom sealing socket 5 formation seal cavities the second road pressurized air shown in the arrow E by making progress among the figure.Keep pressure, observe the commissure and have or not leakage.Whole process is easy, quick, only consumes cheap pressurized air, is fit to cylindrical shell in enormous quantities and detects one by one.
