DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] See also Figure 1-5A compressor air tightness detection device comprises an operating table 1, a detection mechanism, a clamping mechanism and an operating mechanism, wherein the detection mechanism comprises a main body 2, a pressure supply pipe 3, a connector 4, a first sealing gasket 5 and a spiral sleeve 6, wherein the main body 2 is fixedly mounted on the operating table 1, the pressure supply pipe 3 is fixedly connected to the main body 2, the connector 4 is detachably connected to the pressure supply pipe 3, the first sealing gasket 5 is slidably connected to the connector 4, the spiral sleeve 6 is threadedly engaged with the external joint, the clamping mechanism comprises a bidirectional motor 7, a screw 8, a moving rod 9, a clamping sleeve 10, a spring 11 and a base plate 12, wherein the screw 8 is fixedly mounted on the output end of the bidirectional motor 7, the moving rod 9 is threadedly engaged with the screw 8, the clamping sleeve 10 is fixedly mounted on the moving rod 9, the base plate 12 is mounted on the moving rod 9 and is slidably connected to the moving rod 9, and the two ends of the spring 11 are respectively fixedly connected to the base plate 12 and the moving rod 9.

[0029] In this embodiment, the detection mechanism includes a main body 2, a pressure supply pipe 3, a connector 4, a first sealing gasket 5 and a spiral sleeve 6. When in use, different connectors 4 need to be replaced for compressor housings of different models. At this time, the threaded sleeve is rotated, and the threaded sleeve slowly rotates on the connecting pipe 20. Since the connecting head 4 of the connecting pipe 20 is in the joint inside the pressure supply pipe 3, it is also fixed on the pressure supply pipe 3. When the threaded sleeve slowly disengages from the first sealing gasket 5, the sealing gasket is no longer tightly fitted with the pressure supply pipe 3. When the threaded sleeve moves to a sufficiently large distance, the connecting head 4 is pushed to disengage the connecting head 4 on the connecting pipe 20 from the fixing hole 23. Then rotate the connecting pipe 20 so that the connecting head 4 is separated from the pressure supply pipe 3 in the entry hole 22. At this point, remove the connecting head 4 and replace it as mentioned above. After replacing the training joint, when the compressor housing placed on the clamping sleeve 10 slowly moves toward the connecting head 4, the second sealing gasket 24 on the connecting head 4 first contacts the compressor housing, and the compressor housing also enters the sealing groove 25. When everything is sealed, the main body 2 is driven to increase the pressure inside the compressor housing, and the internal pressure sensor of the compressor housing detects the inside of the compressor housing, so that its internal pressure condition is reflected on the display screen 19 on the operating table 1, so that the operator can obtain the detection result.

[0030] In this embodiment, the clamping mechanism includes a bidirectional motor 7, a screw 8, a moving rod 9, a clamping sleeve 10, a spring 11 and a base plate 12. When in use, the compressor housing is placed between the two clamping sleeves 10, so that the bidirectional motor 7 is driven, and the rotation of the screw 8 causes the moving rod 9 to slide in the first slide groove 16 inside the sliding base 13, and causes the two clamping sleeves 10 to clamp the compressor housing. When the sliding base 13 moves, the compressor housing is in contact with the second sealing gasket 24, and the connecting pipe 20 is also squeezed. The connecting pipe 20 is fixed under the limit of the threaded sleeve. After the force is too large, the compressor housing begins to move and contacts the base plate 12. After contacting the base plate 12, it begins to push the base plate 12 to slide on the moving rod 9, and also stretches the spring 11. When the through rod 26 on the base plate 12 moves to the bottom end on the moving rod 9, the limit plate 27 is in close contact with the moving rod 9, limiting the displacement of the base plate 12, thereby fixing the compressor housing.

[0031] In this embodiment, the operating mechanism includes a sliding base 13, a cylinder 14 and a support plate 15. When in use, after the clamping mechanism fixes the compressor housing, the cylinder 14 is driven, and its output end pulls the sliding base 13 and the support plate 15 to slide in the operating table 1. During this process, the sliding base 13 and the support plate 15 slide in the second slide groove 17 and the support slide groove 18 respectively, and the cylinder 14 keeps running at a constant speed, so that the compressor housing on the sliding base 13 slowly contacts the connecting head 4.

[0032] Embodiment 2:

[0033] In summary, when in use, the compressor housing is placed between the two clamping sleeves 10, so that the bidirectional motor 7 is driven, and the rotation of the screw 8 causes the moving rod 9 to slide in the first sliding groove 16 inside the sliding base 13, and the two clamping sleeves 10 clamp the compressor housing. When the sliding base 13 moves, the compressor housing is in contact with the second sealing gasket 24, and the connecting pipe 20 is also squeezed. The connecting pipe 20 is fixed under the limit of the threaded sleeve, and the compressor housing starts to move after being subjected to excessive force and contacts the bottom plate 12. After contacting the bottom plate 12, it starts to push the bottom plate 12 to slide on the moving rod 9, and also pulls The extension spring 11, when the through rod 26 on the bottom plate 12 moves to the bottom end on the moving rod 9, the limit plate 27 is in close contact with the moving rod 9, limiting the displacement of the bottom plate 12, thereby fixing the compressor housing. After the clamping mechanism fixes the compressor housing, the cylinder 14 is driven, and its output end pulls the sliding base 13 and the support plate 15 to slide in the operating table 1. During this process, the sliding base 13 and the support plate 15 slide in the second slide groove 17 and the support slide groove 18 respectively, and the cylinder 14 keeps running at a constant speed, so that the compressor housing on the sliding base 13 slowly contacts with the connector 4, and when the compressor housing is fixed, the cylinder 14 is driven. Before connecting the compressor housing and the connector 4, different connectors 4 need to be replaced for different types of compressor housings. At this time, the threaded sleeve is rotated, and the threaded sleeve slowly rotates on the connecting pipe 20. Since the connecting head 4 of the connecting pipe 20 is in the joint inside the pressure supply pipe 3, it is also fixed on the pressure supply pipe 3. When the threaded sleeve slowly disengages from the first sealing gasket 5, the sealing gasket is no longer tightly fitted with the pressure supply pipe 3. When the threaded sleeve moves to a sufficiently large distance, the connector 4 is pushed to disengage the connector 4 on the connecting pipe 20 from the fixing hole 23, and then the connecting pipe 20 is rotated so that the connector 4 Disconnect the pressure supply pipe 3 in the entry hole 22, and remove the connector 4. When replacing it, follow the above-mentioned procedure. After replacing the training connector, when the compressor housing placed on the clamping sleeve 10 slowly moves toward the connector 4, the second sealing gasket 24 on the connector 4 first contacts the compressor housing, and the compressor housing also enters the sealing groove 25. When everything is sealed, the main body 2 is driven to increase the pressure inside the compressor housing, and the internal pressure sensor inside the compressor housing detects the inside of the compressor housing, thereby reflecting the internal pressure situation on the display screen 19 on the operating table 1, so that the operator can obtain the detection result.

[0034] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
