From the above, the second butt joint assembly 2 of this application, metal gauge head 22 realizes the lift displacement through linear bearing and sliding shaft, and motion stationarity is good, can ensure that metal gauge head 22 can not produce and rock at the lift in-process, guarantees the accurate butt joint of metal gauge head 22 and terminal 52 of compressor 5.

When the compressor insulation and voltage withstand test tool in the specific embodiment shown in fig. 1 to 7 is used for performing the compressor insulation and voltage withstand test, the specific test process is as follows:

firstly, the test fixture is arranged above a test wire body of the compressor 5, the first butt joint assembly 1 and the second butt joint assembly 2 are electrically connected with an insulation pressure-resistant tester, then, the compressor 5 is in place, the driver 31 acts to drive the middle plate 34, the connecting rod 35, the insulation base 33, the lifting plate 32, the first butt joint assembly 1 and the second butt joint assembly 2 to be pressed down, when the annular metal plate 12 of the first butt joint assembly 1 contacts with the air suction pipe 51 of the compressor 5, the first sliding shaft 14 acts upwards to ensure that the annular metal plate 12 is completely contacted with the air suction pipe 51, meanwhile, when the metal measuring head 22 of the second butt joint assembly 2 contacts with the binding post 52 of the compressor 5, the second sliding shaft 26 also acts upwards to ensure that the metal measuring head 22 is completely contacted with the binding post 52, then, the insulation pressure-resistant tester starts to test by high voltage, the driving assembly 3 acts again after the test is completed, the whole device rises, the compressor 5 flows out due to gravity, and the first butt joint assembly 1 and the second butt joint assembly 2 recover to the original position.

From the above description, it can be seen that, according to the insulation and pressure resistance testing tool for the compressor, the test connecting piece is in butt joint with the compressor exhaust pipe instead of in butt joint with the compressor air suction pipe, so that the two test connecting pieces can keep a sufficient distance, the butt joint of the test connecting piece and the compressor is convenient, and the occurrence of the power-on ignition condition caused by the fact that the test connecting piece is too close in distance is avoided, and the problem that the test connecting piece is easy to contact poorly and the abnormal alarm is high caused by ignition in an original industry test mode is solved; meanwhile, the first butt joint assembly connected with the air suction pipe adopts a ring structure capable of lifting and displacing, and can be fully butt-jointed with the air suction pipe so as to be compatible with compressors of different models, thereby accelerating the switching speed of the model of the compressor in the pressure resistance test, and further ensuring that the insulating pressure resistance test tool for the compressor has the characteristics of low false alarm rate and high test efficiency.
