[0032] In this embodiment, the long tube column body 4 needs to be tested for air tightness during the production process. During operation, the long tube column body 4 needs to be placed on the turntable 3 first, wherein the limit column 5 set at the top of the turntable 3 and the limit hole 6 set at the bottom of the long tube column body 4 can allow the long tube column body 4 to be placed on the turntable 3 quickly and accurately. When the long tube column body 4 is placed, the first motor 9 is turned on, and the gear 8 will rotate under the drive of the first motor 9, thereby driving the gear ring 7 to rotate, and then driving the turntable 3 to rotate, thereby driving the long tube column body 4 to rotate, thereby adjusting the orientation of the holes on the long tube column body 4, so as to facilitate the sealing of redundant holes during the subsequent air tightness test.

[0033] like Figures 7 to 9 As shown, one end of the top of the base 2 is fixedly connected to a side plate 10, the top of the side wall is fixedly connected to a top plate 11, one end of the top plate 11 is fixedly connected to a first cylinder 12, and the output end of the first cylinder 12 is fixedly connected to a first blocking block 13; one end of the side plate 10 is fixedly connected to a U-shaped plate 14, the U-shaped plate 14 is inclined, one end of the side wall of the U-shaped plate 14 is fixedly connected to a second cylinder 15, and the output end of the second cylinder 15 is fixedly connected to a second blocking block 16, the side wall of the U-shaped plate 14 away from the second cylinder 15 is fixedly connected to a third cylinder 17, and the output end of the third cylinder 17 is fixedly connected to a third blocking block 18, the middle of the U-shaped plate 14 is fixedly connected to a fourth cylinder 19, and the output end of the fourth cylinder 19 is fixedly connected to a fourth blocking block 20, and the side wall below the U-shaped plate 14 is fixedly connected to a connecting plate 21, one end of the connecting plate 21 is fixedly connected to a fifth cylinder 22, and the output end of the fifth cylinder 22 is fixedly connected to a fifth blocking block 23;

[0034] In this embodiment, after the direction of the holes on the long tube column body 4 is adjusted, it is necessary to block the extra holes on the long tube column body 4. At this time, the first cylinder 12 is opened first. Under the drive of the first cylinder 12, the first blocking block 13 will move downward, thereby blocking the hole at the top of the long tube column body 4. Moreover, under the squeezing of the first blocking block 13, the stability of the long tube column body 4 can be increased. Then the second cylinder 15 and the third cylinder 17 are opened at the same time. The second cylinder 15 and the third cylinder 17 will respectively drive the second blocking block 16 and the third blocking block 18 to move, thereby blocking the two holes at both ends of the side wall of the long tube column body 4. Since the holes at both ends of the side wall of the long tube column body 4 are not at the same height, the U The mold plate 14 is set at an angle, so that the second block 16 and the third block 18 can smoothly block the holes at both ends of the side wall of the long tube column body 4, and then the fourth cylinder 19 is opened. Under the drive of the fourth cylinder 19, the fourth block 20 will move, thereby blocking the hole of the long tube column body 4 at one end of the side plate 10, and finally the fifth cylinder 22 is opened. Under the drive of the fifth cylinder 22, the fifth block 23 will move downward, thereby blocking the hole at one end of the bottom of the long tube column body 4. Through the design of the first block 13, the second block 16, the third block 18, the fourth block 20 and the fifth block 23, the redundant holes of the long tube column body 4 can be blocked, thereby ensuring air tightness, so as to facilitate subsequent air tightness testing.

[0035] like Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 11 As shown, the workbench 1, the base 2 and the turntable 3 are provided with a sealing groove 24 at the center of the turntable 3. A plug-in tube 25 is fixedly connected to the sealing groove 24 at the top of the turntable 3. A vent tube 26 is slidably connected to the inner wall of the plug-in tube 25. The side wall of the vent tube 26 is provided with a plurality of vent holes 27. A plug-in hole 28 is provided at one end of the bottom of the long tube body 4. The plug-in tube 25 is movably connected to the plug-in hole 28.

[0036] In this embodiment, the ventilation tube 26 is designed to inflate the interior of the long tube body 4, thereby performing an air tightness test on the long tube body 4. The design of the sealing groove 24, the plug-in tube 25 and the plug-in hole 28 allows the ventilation tube 26 to move up and down, so that the distance between the top of the ventilation tube 26 and the top plate 11 can be adjusted to facilitate the placement and removal of the long tube body 4.

[0037] like Figure 11 As shown, a sealing block 29 is fixedly connected to the outer wall of the bottom of the vent pipe 26, and the sealing block 29 is movably connected to the sealing groove 24. A connecting pipe 30 is fixedly connected to the bottom of the sealing block 29, and the connecting pipe 30 is in communication with the vent pipe 26;

[0038] In this embodiment, the sealing groove 24 can be blocked by the design of the sealing block 29, thereby ensuring the sealing of the long tube column body 4 and preventing gas from flowing out of the sealing groove 24 during the inflation process. In addition, under the squeezing of the first cylinder 12, the bottom of the long tube column body 4 will fit tightly with the top of the turntable 3, so the gas will not flow out from the gap between the long tube column body 4 and the turntable 3. In addition, the design of the connecting pipe 30 makes it convenient for the staff to connect the ventilation pipe 26 with the air pump, thereby facilitating inflation into the long tube column body 4.

[0039] like Figures 10 to 12 As shown, the two ends of the bottom of the sealing block 29 are respectively fixedly connected to a connecting arm 31, one end of the connecting arm 31 is fixedly connected to a threaded collar 32, the inner wall of the threaded collar 32 is threadedly connected to a screw rod 33, the screw rod 33 is rotatably connected to the workbench 1, an L-shaped plate 34 is provided at one end adjacent to the screw rod 33, the L-shaped plate 34 is fixedly connected to the workbench 1, and the screw rod 33 is rotatably connected to the L-shaped plate 34; one end of the bottom of the screw rod 33 is fixedly connected to a synchronous wheel 35, and the two synchronous wheels 35 are driven by a synchronous belt 39, and one end of the bottom of the L-shaped plate 34 is fixedly connected to a second motor 36, and the output end of the second motor 36 is fixedly connected to one of the screw rods 33;

[0040] In this embodiment, the two screw rods 33 can rotate synchronously through the design of the synchronous wheel 35 and the synchronous belt 39. The two screw rods 33 can be driven to rotate by the second motor 36, thereby driving the threaded ring 32 to move up and down, and then driving the sealing block 29 to move up and down, thereby driving the ventilation tube 26 to move up and down, so as to facilitate the removal and placement of the long tube column body 4.

[0041] like Figure 11 and Figure 12 As shown, a slider 37 is fixedly connected to one end of the bottom of the sealing block 29, and a slide groove 38 is provided at one end of the side wall of the L-shaped plate 34, and the slider 37 is slidably connected to the slide groove 38;

[0042] In this embodiment, the design of the slider 37 and the slide groove 38 allows the sealing block 29 to be slidably connected to the L-shaped plate 34, so that the sealing block 29 is more stable when moving up and down, and the ventilation pipe 26 is more stable when moving up and down.

[0043] Working principle: when in use, first place the long tube column body 4 on the turntable 3, wherein the limiting column 5 provided on the top of the turntable 3 and the limiting hole 6 provided on the bottom of the long tube column body 4 can allow the long tube column body 4 to be placed on the turntable 3 quickly and accurately. When the long tube column body 4 is placed, the first motor 9 is turned on, and the gear 8 rotates under the drive of the first motor 9, thereby driving the gear ring 7 to rotate, and then driving the turntable 3 to rotate, thereby driving the long tube column body 4 to rotate, thereby adjusting the orientation of the holes on the long tube column body 4, so as to facilitate the sealing of excess holes during the subsequent air tightness test. After the direction of the holes on the long tube column body 4 is adjusted, it is necessary to block the excess holes on the long tube column body 4. At this time, first open the first cylinder 12, and Driven by the air cylinder 12, the first blocking block 13 will move downward, thereby blocking the hole at the top of the long tube column body 4, and under the squeezing of the first blocking block 13, the stability of the long tube column body 4 can be increased, and then the second cylinder 15 and the third cylinder 17 will be opened at the same time, and the second cylinder 15 and the third cylinder 17 will respectively drive the second blocking block 16 and the third blocking block 18 to move, thereby blocking the two holes at both ends of the side wall of the long tube column body 4. Since the holes at both ends of the side wall of the long tube column body 4 are not at the same height, the U-shaped plate 14 is tilted, so that the second blocking block 16 and the third blocking block 18 can smoothly block the holes at both ends of the side wall of the long tube column body 4, and then the fourth cylinder 19 is opened, and under the drive of the fourth cylinder 19, the fourth The blocking block 20 will move, thereby blocking the hole of the long tube body 4 at one end of the side plate 10, and finally the fifth cylinder 22 will be opened. Under the drive of the fifth cylinder 22, the fifth blocking block 23 will move downward, thereby blocking the hole at one end of the bottom of the long tube body 4. The design of the first blocking block 13, the second blocking block 16, the third blocking block 18, the fourth blocking block 20 and the fifth blocking block 23 can block the redundant holes of the long tube body 4, thereby ensuring air tightness, so as to facilitate subsequent air tightness testing, and then turn on the second motor 36. The two screw rods 33 can be driven to rotate by the second motor 36, thereby driving the threaded collar 32 to move up and down, and then driving the sealing block 29 to move up and down, thereby driving the vent pipe 26 to extend into the interior of the long tube body 4 When the vent pipe 26 is fully extended into the interior of the long column body 4, the sealing block 29 at the bottom of the vent pipe 26 will block the sealing groove 24 at the bottom of the turntable 3, thereby ensuring the sealing of the long column body 4 and preventing the gas from flowing out of the sealing groove 24 during the inflation process. In addition, under the squeezing of the first cylinder 12, the bottom of the long column body 4 will be tightly attached to the top of the turntable 3, so the gas will not flow out from the gap between the long column body 4 and the turntable 3. At this time, the connecting pipe 30 can be connected to the air pump, and the air pump is used to inflate the vent pipe 26. The air in the vent pipe 26 will flow into the interior of the long column body 4 through the vent hole 27, so as to perform the air tightness test of the long column body 4. When the test is completed, the second motor 36 is turned on again.The second motor 36 drives the vent pipe 26 to move downward, thereby increasing the distance between the top of the vent pipe 26 and the top plate 11, so as to facilitate the removal of the long column body 4.
