DETAILED DESCRIPTION

[0014] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figure 1 To Attachment Figure 3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0015] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0016] Embodiment 1: A sealing gasket sealing performance detection device comprises a detection base 1, two columns 2 are fixedly welded on the left and right sides of the top of the detection base 1, a supporting base 3 is fixedly welded on the top of the column 2, a sealing plug column 18 group is installed below the supporting base 3, a supporting column 4 is fixedly welded on the top of the detection base 1, a connecting platform 5 is fixedly welded on the top of the supporting column 4, four positioning columns 6 are fixedly welded between the connecting platform 5 and the supporting base 3, a gas introduction block 7 is fixedly welded on the top of the connecting platform 5, two gas introduction pipes 8 are inserted and installed on the surface of the gas introduction block 7, the gas introduction pipe 8 is a one-way flow direction from the outside to the inside of the gas introduction block 7, a pressure gauge 9 is fixedly installed on one side of the gas introduction block 7, the pressure gauge 9 is installed on one side of the gas introduction block 7, a workpiece mounting base 10 is fixedly welded above the gas introduction block 7, an installation station is provided on the top of the workpiece mounting base 10, a sealing gasket 11 is installed on the installation station, and the sealing plug column 18 group is correspondingly arranged above the hole groove of the sealing gasket 11.

[0017] A mounting column 12 is installed at the installation position of the workpiece mounting base 10. The mounting column 12 is fixedly welded above the workpiece mounting base 10. A support block 13 is also welded above the workpiece mounting base 10 on one side of the mounting column 12. A sealing gasket 11 is placed on the upper part of the support block 13.

[0018] The support block 13 is fixedly connected to an internal stabilizing block 14 , and ventilation gaps are left between the two sides of the internal stabilizing block 14 and the inner wall of the support block 13 to ensure that the gas can flow normally to the bottom of the sealing gasket 11 .

[0019] A lifting cylinder 15 is fixedly connected to the top of the supporting base 3, and a connecting piece 16 assembled with the piston rod of the lifting cylinder 15 is provided below the lifting cylinder 15. A lifting platform 17 is fixedly connected below the connecting piece 16. The lifting platform 17 is slidably assembled on the outside of the four positioning columns 6, and a group of sealing plug columns 18 are installed below the lifting platform 17.

[0020] The sealing plug rod 18 group includes four sealing plug rods 18, and the sealing plug rods 18 are cylindrical structures.

[0021] Four sets of sliding sleeves 19 are fixedly connected to the bottom of the lifting platform 17, and the sliding sleeves 19 are installed on the outside of the positioning column 6. A buffer support block 20 is fixedly connected to the bottom of the sliding sleeve 19. Four sets of buffer matching pieces 21 are fixedly connected to the top of the connecting platform 5. The upper part of the buffer matching piece 21 is provided with a slot matching the buffer support block 20.

[0022] In an embodiment of the present invention, the sealing gasket 11 is inserted into and stably installed on the top of the support block 13 corresponding to the mounting column 12. Subsequently, the lifting cylinder 15 controls the sealing plug column 18 group to descend in height through the connecting piece 16. Here, the impact force of the descending sealing plug column 18 on the lower structure of the device can be reduced by accurately setting the working stroke of the lifting cylinder 15. At the same time, since the buffer support block 20 is assembled under the lifting platform 17 through the sliding sleeve 19, it is lifted and lowered in height simultaneously with the lifting platform 17. When the lifting platform 17 descends and the sealing plug column 18 collides with the internal stabilizing block 14, the buffer support block 20 is also stuck in the card groove of the buffer matching piece 21 to form a protective effect.

[0023] When the sealing plug 18 collides with the internal stabilizing block 14, it means that the sealing plug 18 has formed an effective seal on the hole groove on the sealing gasket 11. At this time, if the sealing performance of the sealing gasket 11 is excellent, the space below the sealing gasket 11 and the space above it should be isolated from each other. At this time, in order to more concretely present the above experimental results, it is necessary to slowly fill the gas into the gas introduction block 7 and continuously observe the value of the barometer 9. If the value of the barometer 9 does not change much, it means that the space below the sealing gasket 11 is always in a stable state, which indicates that there is a problem with the sealing performance of the sealing gasket 11. If the value of the barometer 9 continues to increase, it means that the pressure in the space below the sealing gasket 11 is gradually increasing, which indicates that the sealing performance of the sealing gasket 11 is excellent.

[0024] The above is a further detailed description of the present invention in combination with a specific implementation method, and it cannot be determined that the specific implementation of the present invention is limited to this; for technical personnel in the technical field to which the present invention belongs and related technical fields, based on the technical solution of the present invention, the expansion and replacement of operating methods and data should all fall within the protection scope of the present invention.
