[0011] By adopting the above technical solution, the driving motor is started. Since the clamping ring at the end of the cylinder is rotatably connected with the rotating ring, the rotation of the first movable column can be realized. When the first movable column and the second movable column are abutted, the sealing head is displaced into the flow channel of the ball head. When the first rotating column is rotated to separate the clamping block and the clamping groove, the cylinder is started in the reverse direction. At this time, the sealing head is located in the flow channel of the ball head and does not move, thereby realizing the isolation and closure of the flow channel. The first sealing component can improve the degree of fit and sealing between the first movable column and the inner wall of the flow channel of the first assembly part, and the second sealing component can improve the degree of fit and sealing between the sealing head and the inner wall of the flow channel of the ball center, thereby providing more complete detection conditions for subsequent sealing detection, thereby further improving the accuracy of subsequent sealing detection results.

[0013] By adopting the above technical solution, the third driving component drives the adjusting disk to rotate, so that the wavy annular outer side of the adjusting disk can abut against the raised portion of the airbag, thereby squeezing the raised portion of the airbag, further increasing the pressure inside the airbag, and making the airbag and the flow channel fit more closely, thereby improving the sealing between the first movable column and the first movable column and the flow channel, providing more complete detection conditions for subsequent sealing detection, thereby further improving the accuracy of subsequent sealing detection results.

[0015] By adopting the above technical solution, after the first movable column and the second movable column are separated from the sealing head at the end respectively, the first movable column and the second movable column are respectively abutted against the sealing head. After the cube driving block on the passive disk completely enters the driving groove, the passive disk rotates under the action of the driving structure. Since the ratchet is installed on the mounting column and the driving groove is opened on the mounting column, the ratchet and the adjusting disk can be driven to rotate. At this time, the ratchet and the pawl are not engaged, and the wavy annular outer side of the adjusting disk abuts against the raised portion of the airbag to achieve the squeezing of the raised portion of the airbag. When the rotation of the adjusting disk is completed, the ratchet has a tendency to rotate in the opposite direction. At this time, the ratchet and the pawl are engaged and locked with each other to keep the adjusting disk stationary. At this time, the cube driving block drives the mounting column to rotate ninety degrees. When the first movable column and the second movable column rotate and abut against the sealing head and separate, the driving structure completely separates the cube driving block from the driving groove for reset. Repeating the above operation can rotate the adjusting plate ninety degrees again, so that the wavy annular outer side of the adjusting disk does not abut against the raised portion of the airbag, so as to achieve the non-squeezing of the raised portion of the airbag.

When the passive disk and the active disk abut against each other, the cube drive block completely enters the drive slot. Since the active disk is fixedly installed, the passive disk and the active disk can rotate relative to each other and the wavy edges can be engaged, thereby realizing the rotation of the cube drive block.
[0018] Optionally, the air intake and exhaust mechanism includes a first air intake and exhaust structure and a second air intake and exhaust structure, the first air intake and exhaust structure including a first air outlet disk and a non-colored gas storage box, the first air outlet disk is arranged on the mounting frame, the air outlet disk is provided with an air outlet and a non-colored gas inlet, the length of the air outlet is set with the moving distance of the first movable column, a gas channel is opened inside the first movable column, the gas channel is connected with the mounting groove, the mounting groove is connected with the end of the first movable column close to the second movable column, when the first movable column is fixedly connected with the sealing head in the horizontal direction, the air outlet is connected with the gas channel, and the non-colored gas inlet is not connected with the gas channel, when the first movable column is separated from the sealing head, the non-colored gas inlet is connected with the gas channel, and the air outlet is not connected with the gas channel, the non-colored gas storage box is arranged at the end of the non-colored gas inlet away from the gas channel, and the second air intake and exhaust structure is arranged on the second movable column and is arranged with the first air intake and exhaust structure.
[0019] By adopting the above technical solution, when the first movable column and the second movable column move closer to each other in the flow channel, the pressure in the flow channel increases, the first movable column and the second movable column are not separated from the sealing head, and the first movable column and the second movable column do not rotate. At this time, the air outlet is connected to the gas channel, and the non-ferrous gas inlet is not connected to the gas channel. Part of the air in the ball valve is discharged through the air outlet. When the first movable column and the second movable column are separated from the sealing head by rotation, the first movable column and the second movable column rotate, and the first movable column and the second movable column move away from each other, the pressure in the flow channel decreases, the non-ferrous gas inlet is connected to the gas channel, and the air outlet is not connected to the gas channel. The non-ferrous gas in the non-ferrous gas storage box enters the ball valve, and then the first movable column and the second movable column are brought closer to each other to pressurize the inside of the ball valve, so as to detect whether the non-ferrous gas is leaking or not, and the sealing of each connection of the ball valve can be detected when the ball valve is opened, thereby further improving the control of the quality of the ball valve and improving the quality of the finished ball valve.
[0020] Optionally, the end of the sealing head away from the first movable column is provided with a chamfer.
[0021] By adopting the above technical solution, the chamfer can facilitate the first movable column and the second movable column to fully enter the flow channel, thereby reducing the wear on the sealing head.
[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the first movable column and the second movable column move closer to each other in the flow channel, the pressure in the flow channel increases, the first movable column and the second movable column are not separated from the sealing head, and the first movable column and the second movable column do not rotate. At this time, the air outlet is connected to the gas channel, and the non-ferrous gas inlet is not connected to the gas channel. Part of the air in the ball valve is discharged through the air outlet. After the first movable column and the second movable column are separated from the sealing head by rotation, the first movable column and the second movable column rotate, and the first movable column and the second movable column move away from each other, the pressure in the flow channel decreases, the non-ferrous gas inlet is connected to the gas channel, and the air outlet is not connected to the gas channel. The non-ferrous gas in the non-ferrous gas storage box enters the ball valve, and then the first movable column and the second movable column are brought closer to each other to pressurize the inside of the ball valve, so as to judge whether the non-ferrous gas is leaking through the color sensor.

Since the clamping ring at the end of the cylinder is connected to the rotating ring, the telescopic end of the cylinder can drive the first movable column to move away from the cylinder when it is extended. The second driving assembly is arranged together with the first driving assembly, so the first movable column and the second movable column can be moved closer to or away from each other, so that the first assembly part, the second assembly part and the flow channel in the ball center can be aligned, thereby improving the accuracy of the installation position of the ball center; 3.

When the ball valve is small, there may be limitations on the installation position when adjusting the airbag by means of a telescopic rod or the like. Therefore, the present application is more universal in that the wavy annular outer side of the adjusting disk is rotated to abut against the raised part of the airbag to squeeze the airbag.

DETAILED DESCRIPTION
[0025] The following is combined with Figure 1-4 This application is described in further detail.
[0026] The present application discloses an integrated device for automatic assembly and detection of a ball valve, referring to Figure 1 and Figure 2A ball valve automatic assembly and detection integrated device comprises a mounting frame 1 and a ball valve 2. The ball valve 2 is arranged on the mounting frame 1. The ball valve 2 comprises a first assembly part 21, a second assembly part 22 and a ball core 23. The first assembly part 21, the second assembly part 22 and the ball core 23 are all provided with flow channels. The ball core 23 is arranged between the first assembly part 21 and the second assembly part 22. A first moving column 3 and a second moving column 4 are arranged on the mounting frame 1. The first moving column 3 and the second moving column 4 are symmetrically arranged. The diameters of the first moving column 3 and the second moving column 4 are set to be the same as the diameter of the flow channel. The first moving column 3 and the second moving column 4 are arranged in a socket-type manner on the flow channel. When the ball valve 2 is in the moving channel, it is used to align the flow channels of the first assembly part 21, the second assembly part 22 and the ball center 23. The mounting frame 1 is provided with a first driving component 5 and a second driving component for making the first moving column 3 and the second moving column 4 approach each other and rotate relative to each other. The first moving column 3 and the second moving part are provided with a detection device 6 for performing sealing detection on each connection of the ball valve 2 when the ball valve 2 is opened. The first moving column 3 and the second moving column 4 are provided with an intake and exhaust mechanism 8 for discharging the gas inside the ball valve 2 and conveying the colored gas into the ball valve 2. The mounting frame 1 is also provided with a color sensor 9.
[0027] Under the action of the first driving assembly 5 and the second driving assembly, the first moving column 3 and the second moving column 4 are inserted into the flow channels in the first assembly part 21, the second assembly part 22 and the ball center 23. Since the first moving column 3 and the second moving column 4 are symmetrically arranged, the flow channels in the first assembly part 21, the second assembly part 22 and the ball center 23 can be aligned, thereby improving the accuracy of the installation position of the ball center 23. In the prior art, the sealing detection of the ball valve 2 needs to be performed by closing the ball valve 2, so the sealing problem caused by the change of the mechanical mechanism when the ball valve 2 is opened and closed may be ignored. Therefore, when it is necessary to detect the sealing performance of the opened ball valve 2, the detection component in the present application cooperates with the air intake and exhaust mechanism 8, by removing part of the gas in the ball valve 2 and then adding colored gas, and according to whether the colored gas is leaking, the sealing of each joint of the ball valve 2 can be detected when the ball valve 2 is opened, so as to further improve the control of the quality of the ball valve 2 and the quality of the finished ball valve 2. When the color sensor 9 detects the color of the colored gas, it means that the sealing performance of the ball valve 2 does not meet the requirements. When the color sensor 9 does not detect the appearance of other colors, it means that the sealing performance of the ball valve 2 is qualified.
[0028] Reference Figure 2 and Figure 3The first driving assembly 5 includes a driving motor 51, a cylinder 52, a rotating ring 53 and a clamping ring 54. The fixed end of the cylinder 52 is arranged on the mounting frame 1, the telescopic end of the cylinder 52 is connected to the end of the first moving column 3 away from the second moving column 4, the clamping ring 54 is arranged on the telescopic end of the cylinder 52, the rotating ring 53 is arranged on the end of the first moving column 3 away from the second moving column 4, the rotating ring 53 is rotatably arranged in the clamping ring 54, the driving motor 51 is arranged on the mounting frame 1, the output end of the driving motor 51 is connected to the end of the first moving column 3 away from the second moving column 4, the second driving assembly is arranged on the second moving column 4, and is arranged together with the first driving assembly 5.
[0029] Start the cylinder 52. Since the clamping ring 54 at the end of the cylinder 52 is connected to the rotating ring 53, the telescopic end of the cylinder 52 can drive the first movable column 3 to move away from the cylinder 52 when it is extended. The second driving component is arranged together with the first driving component 5. Therefore, the first movable column 3 and the second movable column 4 can be moved closer to or farther away from each other, so that the flow channels in the first assembly part 21, the second assembly part 22 and the ball center 23 can be aligned, thereby improving the accuracy of the installation position of the ball center 23.
[0030] Reference Figure 2 and Figure 4 The detection device 6 includes a first sealing mechanism 61 and a second sealing mechanism. The first sealing mechanism 61 is arranged at the end of the first moving column 3 close to the second moving column 4. The first sealing mechanism 61 includes a sealing head 611, a clamping block 612, a first sealing component 613 and a second sealing component. The clamping block 612 is arranged at the end of the first moving column 3 close to the second moving column 4. A clamping groove 614 is provided on the sealing head 611. The clamping block 612 is arranged in an "L" shape. The clamping groove 614 corresponds to the clamping groove 614 in an "L" shape. The clamping block 612 is located in the clamping groove 614. When the first movable column 3 and the sealing head 611 are clamped in the horizontal direction, the first sealing component 613 is arranged on the first movable column 3, and is used to improve the degree of fit and sealing between the first movable column 3 and the inner wall of the flow channel of the first assembly part 21. The second sealing component is arranged on the sealing head 611, and improves the degree of fit and sealing between the sealing head 611 and the inner wall of the flow channel of the center of the ball 23. The second sealing mechanism is arranged at the end of the second movable column 4 close to the first movable part, and is arranged together with the first sealing mechanism 61. The end of the sealing head 611 away from the first movable column 3 is chamfered.
[0031] Start the driving motor 51. Since the clamping ring 54 at the end of the cylinder 52 is rotatably connected with the rotating ring 53, the first movable column 3 can be rotated. When the first movable column 3 and the second movable column 4 are abutted, the sealing head 611 is displaced into the flow channel of the ball head. When the first rotating column rotates to separate the clamping block 612 and the clamping groove 614, the cylinder 52 is started in reverse. At this time, the sealing head 611 is located in the flow channel of the ball head and does not move, thereby realizing the isolation and closure of the flow channel. The first sealing component 613 can improve the degree of fit and sealing between the first movable column 3 and the inner wall of the flow channel of the first assembly part 21. The second sealing component can improve the degree of fit and sealing between the sealing head 611 and the inner wall of the flow channel of the ball center 23, providing more complete detection conditions for subsequent sealing detection, thereby further improving the accuracy of subsequent sealing detection results. The chamfering can facilitate the first movable column 3 and the second movable column 4 to fully enter the flow channel, thereby reducing the wear on the sealing head 611.

[0033] The third driving assembly 7 drives the adjusting disk 6132 to rotate, so that the wavy annular outer side of the adjusting disk 6132 can abut against the raised portion 6134 of the airbag 6131, thereby squeezing the raised portion 6134 of the airbag 6131, further increasing the pressure inside the airbag 6131, and making the airbag 6131 and the flow channel fit more closely, thereby improving the sealing between the first movable column 3 and the first movable column 3 and the flow channel, providing more complete detection conditions for subsequent sealing detection, thereby further improving the accuracy of subsequent sealing detection results.
[0034] Reference Figure 2 and Figure 4The third driving assembly 7 includes a mounting column 71, a ratchet 72, a pawl 73, a passive disk 74 and a driving structure 75.

[0035] After the first movable column 3 and the second movable column 4 are separated from the sealing head 611 at the end, the first movable column 3 and the second movable column 4 are respectively abutted against the sealing head 611. After the cubic driving block 77 on the passive disk 74 completely enters the driving groove, the passive disk 74 rotates under the action of the driving structure 75. Since the ratchet 72 is installed on the mounting column 71 and the driving groove is provided on the mounting column 71, the ratchet 72 and the adjusting disk 6132 can be driven to rotate. At this time, the ratchet 72 and the pawl 73 are not engaged, and the wavy annular outer side of the adjusting disk 6132 abuts against the raised portion 6134 of the airbag 6131, so as to squeeze the raised portion 6134 of the airbag 6131. The ratchet 72 tends to rotate in the opposite direction after the adjustment disk 6132 has completed its rotation. At this time, the ratchet 72 and the pawl 73 engage and lock with each other to keep the adjustment disk 6132 stationary. At this time, the cube drive block 77 drives the mounting column 71 to rotate ninety degrees. When the first movable column 3 and the second movable column 4 rotate and abut against the sealing head 611 and then separate, the drive structure 75 completely separates the cube drive block 77 from the drive groove for reset. Repeat the above operation to rotate the adjustment plate ninety degrees again, so that the wavy annular outer side of the adjustment disk 6132 does not abut against the raised portion 6134 of the airbag 6131, thereby achieving non-squeezing of the raised portion 6134 of the airbag 6131.
[0036] Reference Figure 2 and Figure 4 The driving structure 75 includes an active disk 751 and a torsion spring 752. The active disk 751 is fixedly arranged in the rotating groove. The torsion spring 752 is arranged in the rotating groove, and one end of the torsion spring is connected to the bottom of the rotating groove, and the other end is connected to the passive disk 74. The ends of the passive disk 74 and the active disk 751 that are close to each other are arranged in a wave shape and staggered with each other.
[0037] The ends of the passive disk 74 and the active disk 751 that are close to each other are arranged in a wave shape and are staggered with each other. When the passive disk 74 and the active disk 751 are in contact, the cube driving block 77 completely enters the driving groove. Since the active disk 751 is fixedly installed, the passive disk 74 and the active disk 751 can rotate relative to each other and the wavy edges can be engaged, thereby realizing the rotation of the cube driving block 77.
[0038] Reference Figure 2 and Figure 3 The air intake and exhaust mechanism 8 includes a first air intake and exhaust structure 81 and a second air intake and exhaust structure. The first air intake and exhaust structure 81 includes a first air outlet plate 811 and a non-colored gas storage box 812. The first air outlet plate 811 is arranged on the mounting frame 1. The air outlet plate is provided with an air outlet 813 and a non-colored gas inlet. The length of the air outlet 813 is set with the moving distance of the first moving column 3. A gas channel is provided inside the first moving column 3. The gas channel is connected to the mounting groove. The mounting groove is connected to the first moving column 3 near the second moving column 4. The ends are connected, and when the first movable column 3 is fixedly connected with the sealing head 611 in the horizontal direction, the air outlet 813 is connected with the gas channel, and the non-colored gas inlet is not connected with the gas channel; when the first movable column 3 is separated from the sealing head 611, the non-colored gas inlet is connected with the gas channel, and the air outlet 813 is not connected with the gas channel. The non-colored gas storage box 812 is arranged at the end of the non-colored gas inlet away from the gas channel, and the second air intake and exhaust structure is arranged on the second movable column 4, and is arranged together with the first air intake and exhaust structure 81.
[0039] When the first movable column 3 and the second movable column 4 move closer to each other in the flow channel, the pressure in the flow channel increases, the first movable column 3 and the second movable column 4 are not separated from the sealing head 611, and the first movable column 3 and the second movable column 4 are not rotating. At this time, the air outlet 813 is connected to the gas channel, and the non-ferrous gas inlet is not connected to the gas channel. Part of the air in the ball valve 2 is discharged through the air outlet 813. After the first movable column 3 and the second movable column 4 are separated from the sealing head 611 by rotation, the first movable column 3 and the second movable column 4 are rotating. After the first movable column 3 and the second movable column 4 move away from each other, the pressure in the flow channel decreases, the non-ferrous gas inlet is connected to the gas channel, and the air outlet 813 is not connected to the gas channel. The non-ferrous gas in the non-ferrous gas storage box 812 enters the ball valve 2, and then the first movable column 3 and the second movable column 4 are brought close to each other to pressurize the inside of the ball valve 2, so as to detect whether the non-ferrous gas leaks or not. When the ball valve 2 is opened, the sealing of each joint of the ball valve 2 can be detected, thereby further improving the control of the quality of the ball valve 2 and improving the quality of the finished ball valve 2.
[0040] The implementation principle of the ball valve automatic assembly and detection integrated device in the embodiment of the present application is: When it is necessary to align the flow channels in the first assembly part 21, the second assembly part 22 and the ball center 23, the cylinder 52 is started. Since the clamping ring 54 at the end of the cylinder 52 is connected to the rotating ring 53, the telescopic end of the cylinder 52 can drive the first movable column 3 to move away from the cylinder 52 when it is extended. The second driving component is arranged with the first driving component 5, so the first movable column 3 and the second movable column 4 can be brought close to each other. Since the first movable column 3 and the second movable column 4 are symmetrically arranged, the flow channels in the first assembly part 21, the second assembly part 22 and the ball center 23 can be aligned. When it is necessary to test the sealing performance of the opened ball valve 2, the first movable column 3 and the second movable column 4 move closer to each other in the flow channel. At this time, the air outlet 813 is connected to the gas channel, and the non-ferrous gas inlet is not connected to the gas channel. Part of the air in the ball valve 2 is discharged through the air outlet 813. After the first movable column 3 and the second movable column 4 and the sealing head 611 are rotated and separated, the first movable column 3 and the second movable column 4 move away from each other, the pressure in the flow channel decreases, the non-ferrous gas inlet is connected to the gas channel, and the air outlet 813 is not connected to the gas channel. The non-ferrous gas in the non-ferrous gas storage box 812 enters the ball valve 2, and then the first movable column 3 and the second movable column 4 are moved closer to each other to pressurize the inside of the ball valve 2, so as to detect whether the non-ferrous gas is leaking or not. When the ball valve 2 is opened, the sealing of each joint of the ball valve 2 can be tested, thereby further improving the control of the quality of the ball valve 2 and improving the quality of the finished ball valve 2.
