Technical Field

[0001] The utility model relates to the technical field of air tightness detection tooling, in particular to an air tightness detection tooling for a metal tube shell. Background Art

[0002] As one of the important components of integrated circuits, the metal tube shell can support, protect, transmit electricity, seal and dissipate heat for the integrated circuit. Among them, the glass insulator and lead parts that constitute the tube shell are important components of electronic components such as sealed relays, crystal elements and connectors. Its sealing performance is directly related to the quality of the above-mentioned electronic components. Before installing and using the metal tube shell, it is necessary to use an airtightness detection tool to test the airtightness of the metal tube shell.

[0003] Before installing and using the metal pipe shell, an airtightness detection tool is required. Among them, the "metal pipeline sealing performance detection device" disclosed with the publication number "CN210221412U" has solved the various technical disadvantages of the traditional metal pipeline sealing performance detection device, which is complicated to fix and install the metal pipeline body during use, greatly reducing the convenience of its fixation, and the operation is complicated, requiring professionals to perform the detection, which greatly reduces the convenience of its operation.

[0004] However, there are still many defects in the actual use of airtightness detection tools with similar structures, such as: the device in the prior art is not convenient for testing multiple groups and multiple specifications of metal tube shells, which makes the device easily restricted by the shape of the metal tube shells, and is not convenient for testing the airtightness of metal tube shells of different shapes, which limits the scope of application of the device, reduces the convenience of using the device, and is not convenient for promoting the use of the device. Therefore, a metal tube shell airtightness detection tool is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a metal tube shell airtightness detection tool to solve the above problems.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a metal tube shell airtightness detection tool, comprising a tooling table, a cover is movably installed on the top of the tooling table through hinges, a plurality of groups of adaptive mechanisms for fixing the metal tube shell are equidistantly installed on the top of the cover, and a sealing mechanism is fixedly installed on the top of the tooling table;

[0007] The adaptive mechanism comprises a spring sleeve seat, a support rod is fixedly installed at the bottom end of the spring sleeve seat, and a pressure holding seat is fixedly installed at the bottom end of the support rod;

[0008] The sealing mechanism includes an airbag, an air inlet pipe is fixedly installed on one side of the top of the airbag, a first solenoid valve tube is fixedly installed on one end of the air inlet pipe, an air outlet pipe is fixedly installed on the other side of the top of the airbag, and a second solenoid valve tube is fixedly installed on one end of the air outlet pipe.

[0009] Preferably, a plurality of installation grooves are equidistantly arranged inside the workbench, and exhaust pipes are fixedly installed inside the installation grooves.

[0010] Preferably, a locking piece is threadedly mounted on one side of the cover, and a display screen is fixedly mounted on the front side of the cover.

[0011] Preferably, two sets of fixing frames are fixedly installed on the top of the cover, a linkage frame is movably installed on one side of the fixing frame, and one side of the linkage frame is fixedly connected to one side of the spring sleeve seat, and a positioning bolt is threadedly installed on the front side of the linkage frame.

[0012] Preferably, a third solenoid valve tube is fixedly installed on one side of the top of the cover, and a fourth solenoid valve tube is fixedly installed on the other side of the top of the cover.

[0013] Preferably, a fifth solenoid valve tube is fixedly installed at the bottom end of the air extraction tube, and a docking tube is fixedly installed at one end of the fifth solenoid valve tube.

[0014] Beneficial Effects

[0015] The utility model provides a metal tube shell air tightness detection tool. Compared with the prior art, it has the following beneficial effects:

[0016] 1. After being connected to an external air pump through the first solenoid valve tube, the first solenoid valve tube can be powered on and turned on to allow the air pump to deliver high-pressure air to the inside of the intake pipe, and then the air can be delivered to the inside of the airbag through the intake pipe, so that the airbag can expand rapidly in volume. The airbag that has expanded in volume can be conveniently fitted and fixed to metal tube shells of various shapes. When it is necessary to take metal tube shells of various shapes, the second solenoid valve tube can be powered on and turned on to allow the air inside the airbag to be discharged to a designated area through the outlet pipe. The airbag can be used in conjunction with the first solenoid valve tube and the second solenoid valve tube to achieve the function of improving the compatibility of the device, avoid the problem that the device is easily restricted by the shape of the metal tube shell, and facilitate the air tightness testing of multiple groups and multiple metal tube shells, thereby expanding the scope of application of the device and increasing the convenience of using the device, so as to facilitate the popularization and use of the device.

[0017] 2. The operator can rotate the cover to drive the pressing seat to move in an arc position to the top of the metal tube shell to resist, and then the high elastic force of the spring sleeve can drive the pressing seat to resist the top of the metal tube shell through the support rod, and the operator can manually pull the linkage frame to move the vertical position. The linkage frame can drive the pressing seat to apply pressure to the top of the metal tube shell through the spring sleeve, so that the metal tube shell fits the inside of the installation groove, and the operator can manually rotate the positioning bolt to fix the moving position of the linkage frame, thereby fixing the moving position of the pressing seat, thereby realizing the function of improving the contact sealing between the metal tube shell and the device, avoiding the problem of reduced metal tube shell detection accuracy caused by the metal tube shell being affected by the installation sealing, and ensuring the accuracy of the metal tube shell detection using the device.

[0029] The installation groove can provide an installation position for the exhaust pipe 101, and the exhaust pipe 101 can be used to extract the air inside the metal tube shell to be tested, so as to facilitate the subsequent delivery of the air inside the metal tube shell to be tested to the outside helium mass spectrometer leak detector for detection;

[0030] By energizing the third solenoid valve tube 5, the gas containing helium can be delivered to the inside of the cover 2, and then by energizing the fourth solenoid valve tube 501, the air containing helium after detection inside the cover 2 can be extracted;
