Description

Technical Field

[0001] This invention belongs to the field of valve installation, specifically a clamping tool for valve installation. Background Technology

[0002] In industrial pipeline engineering, municipal water supply systems, and chemical equipment installation, valves, as core components of fluid control, directly affect the stability of system operation due to their installation accuracy and efficiency. Currently, most valve installations rely on manual assistance with simple tooling or general-purpose robotic arms. However, in automated production lines, the connection response speed, positioning accuracy, and locking reliability of existing tools can no longer meet the requirements for efficient assembly. Therefore, a clamping tool for valve installation is proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: the installation process of the robot arm and the load-bearing structure requires manual control and locking or the use of detection sensors and microcontrollers, resulting in slow response speed or the need for an additional stable power supply system, the existing pneumatic system structure cannot be directly used, which greatly increases the manufacturing and maintenance costs.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a clamping tool for valve installation, comprising a bearing structure, a quick assembly mechanism, a vision system and a pneumatic locking mechanism. The bearing structure includes a six-axis flange seat and a quick locking platform. A quick locking platform is fixedly connected to the upper and lower sides of the six-axis flange seat, and a pneumatic locking mechanism is provided on the quick locking platform. A vision system is provided at one end of the quick locking platform, and the quick locking platform is connected to the quick assembly mechanism through the pneumatic locking mechanism.

[0006] The quick assembly mechanism includes a quick connector and a connecting plate. The connecting plate is located on the side of the quick connector away from the quick locking platform. Several air pipe connectors are located on the outer sides of both the quick connector and the quick locking platform.

[0007] As a preferred technical solution for a clamping tool for valve installation, the vision system includes a camera housing, a connecting frame, a cover plate, and a long groove. Several connecting frames are provided at one end of the six-axis flange seat, and a camera housing is provided at the end of the connecting frame away from the six-axis flange seat. A 3D camera and a 2D camera are provided in the inner cavity of the camera housing. A long groove is provided on each side of the camera housing, and a drive mechanism is provided on the inner side of the long groove. The drive mechanism is connected to one end of the cover plate, and the cover plate is slidably connected to the camera housing.

[0008] The drive mechanism includes a cylinder, a support frame, and a connecting bolt. A support frame is provided on each side of the bottom of the camera housing. A cylinder is provided on the support frame. The movable end of the cylinder is connected to a connecting bolt. The top of the connecting bolt passes through the cover plate and is threaded with a nut.

[0009] The cylinder controls the connecting bolt to move the cover plate, opening and exposing the inner cavity of the camera housing, allowing the 2D and 3D cameras to receive external light for shooting.

[0010] As a preferred technical solution for a clamping tool for valve installation, the pneumatic locking mechanism includes a clamping assembly, a locking outer cylinder, and a ring. The clamping assembly includes a locking pin and an intermediate cylinder. A receiving pin is fixedly provided on the inner bottom wall of the locking outer cylinder, and a ring is provided on the top of the receiving pin. The locking pins are distributed around the ring, and there are three locking pins. The locking pins are slidably connected to the upper side of the ring. The bottom end of the locking pin extends into the locking outer cylinder. The thickness of the top of the locking pin is less than the thickness of the bottom of the locking pin. Each quick-connect seat has three locking slots.

[0011] The locking post has a locking hole, and the inner wall of the locking groove is provided with a locking block. The locking post pulls the limiting cylinder to overcome the elasticity of the second tension spring and separates it, so that the locking block is inserted into the locking hole, and the quick assembly mechanism can quickly connect with the load-bearing structure.

[0012] As a preferred technical solution for a clamping tool for valve installation, the clamping assembly also includes an annular airbag. The bottom of the receiving column is fitted with an annular airbag. The inner side of the annular airbag is fixedly connected to the outer side of the receiving column. Several outer plates are evenly arranged on the outer side of the annular airbag. The outer plates are movably abutted against the locking column. The annular airbag is connected to the first air pipe through a pipe. One end of the first air pipe is sequentially provided with a one-way valve and a switch valve. The one-way valve is connected to a high-pressure air pump through a pipe.

[0013] A one-way valve prevents gas from being discharged or depressurized once the air tube passes through the pipe connected to the high-pressure air pump.

[0014] As a preferred technical solution for a valve installation clamping tool, the clamping assembly further includes a translational limiting component. Each pair of locking posts is connected to a translational limiting component, which includes an intermediate cylinder, a limiting cylinder, and a second tension spring. A limiting cylinder is provided on each side of the locking post, and each end of the intermediate cylinder is inserted into a limiting cylinder. Two limiting cylinders connected to the same intermediate cylinder are connected by the second tension spring. A movable air valve assembly is provided at the end of the air pipe furthest from the one-way valve. The movable air valve assembly includes a closed cylinder, a movable post, an air outlet, a compression spring, and a sealing ring. Several sealed cylinders are evenly arranged on the quick-locking platform. A movable column is movably inserted into the sealed cylinder. A compression spring is installed between the bottom end of the movable column and the inner bottom wall of the sealed cylinder. A sealing ring made of rubber is installed at the top of the inner wall of the sealed cylinder. The inner side of the sealing ring is movably connected to the outer side of the movable column. An air vent is opened on the movable column. An elongated groove is opened on the inner side of the movable column. The top of the elongated groove is connected to the air vent. The elongated groove is a blind hole with an opening at the bottom and a closed top. The opening at the bottom of the elongated groove is connected to the inner cavity of the sealed cylinder. The sealed cylinder is connected to the air pipe through a pipe.

[0015] The movable column compresses and squeezes the spring into the closed cylinder. During this process, the vent reaches the position of the sealing ring, and the vent is covered and sealed by the sealing ring.

[0016] As a preferred technical solution for a clamping tool for valve installation, an air pipe is connected to an air pressure maintaining system via a pipeline. The air pressure maintaining system includes an air tank, an air chamber, a tension spring, an elastic sealing diaphragm, a connecting block, a separating frame, and copper springs. The air tank has an air chamber inside, with an elastic sealing diaphragm at the top. A connecting block is located in the middle of the elastic sealing diaphragm. A tension spring is positioned between the lower side of the connecting block and the inner bottom wall of the air chamber. Two copper springs are movably connected to the inner top wall of the air chamber. A connecting block is also located in the middle of the outer side of the elastic sealing diaphragm. A separating frame is provided in the middle of the connecting block. The separating frame can separate two copper springs. When the air outlet is closed, a large amount of gas from the first air pipe enters the gas chamber. The gas compresses the elastic sealing membrane in the gas chamber and deforms it. The connecting block pulls the first tension spring to lengthen. The connecting block moves and carries the separating frame between the two copper springs, causing the two copper springs to separate. This causes the high-pressure air pump switch circuit to be cut off, stopping the high-pressure air pump from supplying air. The gas in the gas chamber can maintain the stable air pressure in the pneumatic locking mechanism, preventing the locking pin from releasing the locking groove or even releasing the clamp due to partial gas leakage, thus causing the two to separate.

[0017] As a preferred technical solution for a clamping tool for valve installation, a robotic arm is provided on the connecting plate, which can clamp objects.

[0018] The advantages of the valve installation clamping tool of the present invention are as follows: by using the locking post, the annular air bladder and the translational limiting component, the quick locking platform and the quick connecting seat can be quickly and reliably connected and unlocked; the locking post squeezes the locking groove under the expansion of the annular air bladder, and with the design of the locking block and the locking hole, quick locking and separation can be achieved without manual operation or complex circuit control, which significantly improves the installation efficiency.

[0019] By coordinating the design of the pneumatic locking mechanism and the air pressure maintenance system, the existing pneumatic system can be directly utilized, avoiding the need for an additional power supply system. The air pressure maintenance system, through components such as an air chamber, an elastic sealing diaphragm, and a tension spring, automatically cuts off the high-pressure air pump circuit when the air outlet is closed, maintaining stable air pressure within the pneumatic locking mechanism and reducing manufacturing and maintenance costs.

[0020] The pneumatic locking mechanism achieves precise control of air pressure through a one-way valve, a switching valve, and a movable air valve assembly. When the air outlet is closed by the sealing ring, the air pressure maintenance system disconnects the copper spring through the separation frame, cuts off the high-pressure air pump circuit, ensures stable air pressure, and avoids the locking pin and locking groove from being released or the clamping failure due to gas leakage.

[0021] The load-bearing structure provides high rigidity support through a six-axis flange and a quick-locking stage. The quick-assembly mechanism's quick-connect seats and connecting plates enable modular assembly, facilitating rapid disassembly and assembly. Storage boxes within the vision system facilitate the storage of camera calibration accessories and cleaning tools, simplifying on-site maintenance and further reducing maintenance costs.

[0040] like Figures 1-12 As shown, the present invention proposes a clamping tool for valve installation, including a bearing structure 100, a quick assembly mechanism 200, a vision system 300, and a pneumatic locking mechanism 400. The bearing structure 100 includes a six-axis flange seat 101 and a quick locking platform 102. A quick locking platform 102 is fixedly connected to the upper and lower sides of the six-axis flange seat 101, and a pneumatic locking mechanism 400 is provided on the quick locking platform 102. A vision system 300 is provided at one end of the quick locking platform 102. The quick locking platform 102 is connected to the quick assembly mechanism 200 through the pneumatic locking mechanism 400.

[0041] The quick assembly mechanism 200 includes a quick connector 201 and a connecting plate 202. The connecting plate 202 is provided on the side of the quick connector 201 away from the quick locking table 102. Several air pipe connectors are provided on the outer sides of both the quick connector 201 and the quick locking table 102.

[0042] The vision system 300 includes a camera housing 301, a connecting bracket 302, a cover plate 303, and a long groove 305. Several connecting brackets 302 are provided at one end of the six-axis flange seat 101. The camera housing 301 is provided at the end of the connecting bracket 302 away from the six-axis flange seat 101. A 3D camera 308 and a 2D camera 310 are provided in the inner cavity of the camera housing 301. A long groove 305 is opened on each side of the camera housing 301. A drive mechanism is provided on the inner side of the long groove 305. The drive mechanism is connected to one end of the cover plate 303. The cover plate 303 is slidably connected to the camera housing 301.

[0043] The drive mechanism includes a cylinder 304, a support frame 306 and a connecting bolt 307. A support frame 306 is provided on each side of the bottom end of the camera housing 301. A cylinder 304 is provided on the support frame 306. The movable end of the cylinder 304 is connected to the connecting bolt 307. The top end of the connecting bolt 307 passes through the cover plate 303 and is threaded with a nut.

[0044] The nut and connecting bolt 307 lock one end of the cover plate 303. The movable end of the cylinder 304 controls the connecting bolt 307 to move the cover plate 303, so that the inner cavity of the camera housing 301 is opened and exposed, allowing the 2D camera 310 and the 3D camera 308 to receive external light and thus take pictures.

[0045] The pneumatic locking mechanism 400 includes a clamping assembly, a locking outer cylinder 401, and a ring 417. The clamping assembly includes locking pins 402 and an intermediate cylinder 403. A receiving pin 413 is fixedly provided on the inner bottom wall of the locking outer cylinder 401. A ring 417 is provided on the top of the receiving pin 413. The locking pins 402 are distributed around the ring 417. There are three locking pins 402. The locking pins 402 are slidably connected to the upper side of the ring 417. The bottom end of the locking pin 402 extends into the locking outer cylinder 401. The thickness of the top of the locking pin 402 is less than the thickness of the bottom of the locking pin 402. Three locking slots 203 are provided on each quick-connect seat 201. Three locking outer cylinders 401 are evenly arranged on each quick-locking platform 102. The locking slots 203 are correspondingly inserted into the locking outer cylinders 401.

[0046] The locking post 402 has a locking hole, and the inner wall of the locking groove 203 is provided with a locking block. The locking post 402 pulls the limiting cylinder 415 to overcome the elasticity of the tension spring 416 and separates it, so that the locking block is inserted into the locking hole, and the quick assembly mechanism 200 is quickly connected to the bearing structure 100.

[0047] The clamping assembly also includes an annular airbag 411. The bottom of the receiving column 413 is fitted with the annular airbag 411. The inner side of the annular airbag 411 is fixedly connected to the outer side of the receiving column 413. Several outer plates 412 are evenly arranged on the outer side of the annular airbag 411. The outer plates 412 are movably abutted against the locking column 402. The annular airbag 411 is connected to the air tube 408 through a pipe. One end of the air tube 408 is sequentially provided with a one-way valve 409 and a switch valve 410. The one-way valve 409 is connected to a high-pressure air pump through a pipe.

[0048] One-way valve 409 prevents gas from being discharged or depressurized through the gas pipe 408 via the pipe connected to the high-pressure air pump.

[0049] The clamping assembly also includes a translational limiting assembly. Each pair of locking posts 402 is connected to a translational limiting assembly, which includes an intermediate cylinder 403, a limiting cylinder 415, and a second tension spring 416. A limiting cylinder 415 is provided on each side of the locking post 402. Each end of the intermediate cylinder 403 is inserted into a limiting cylinder 415. Two limiting cylinders 415 connected to the same intermediate cylinder 403 are connected by a second tension spring 416. A movable air valve assembly is provided at the end of the air pipe 408 furthest from the one-way valve 409. The movable air valve assembly includes a closed cylinder 405, a movable post 404, an air outlet 407, a compression spring 406, and a sealing ring 414. The quick-locking platform 102 is evenly equipped with… Several sealed cylinders 405 are provided. A movable column 404 is movably inserted into the sealed cylinder 405. A compression spring 406 is provided between the bottom end of the movable column 404 and the inner bottom wall of the sealed cylinder 405. A sealing ring 414 is provided at the top of the inner wall of the sealed cylinder 405. The sealing ring 414 is made of rubber. The inner side of the sealing ring 414 is movably connected to the outer side of the movable column 404. An air outlet 407 is provided on the movable column 404. An elongated groove is provided on the inner side of the movable column 404. The top of the elongated groove is connected to the air outlet 407. The elongated groove is a blind hole with an opening at the bottom and a closed top. The opening at the bottom of the elongated groove is connected to the inner cavity of the sealed cylinder 405. The sealed cylinder 405 is connected to the air pipe 408 through a pipe.

[0050] The movable column 404 compresses and squeezes the spring 406 into the closed cylinder 405. During the process, the vent 407 reaches the position of the sealing ring 414. The vent 407 is covered and sealed by the sealing ring 414. The movable column 404 and the connecting plate 202 move and abut against each other.

[0051] Air tube 408 is connected to a pressure maintaining system 500 via a pipe. The pressure maintaining system 500 includes a pressure tank 501, an air chamber 502, a tension spring 503, an elastic sealing membrane 504, a connecting block 505, a separation frame 506, and copper springs 507. The pressure tank 501 has an air chamber 502 inside. An elastic sealing membrane 504 is located at the top of the air chamber 502. A connecting block 505 is located in the middle of the elastic sealing membrane 504. A tension spring 503 is located between the lower side of the connecting block 505 and the inner bottom wall of the air chamber 502. Two copper springs 507 are located on the inner top wall of the air chamber 502 and are movably connected. A connecting block 505 is also located in the middle of the outer side of the elastic sealing membrane 504. A separation frame 506 is provided in the middle of 05. The separation frame 506 can separate two copper springs 507. When the air outlet 407 is closed, a large amount of gas from the air pipe 408 enters the air chamber 502. The gas in the air chamber 502 compresses the elastic sealing membrane 504 and deforms it. The connecting block 505 pulls the tension spring 503 to lengthen. The connecting block 505 moves and causes the separation frame 506 to insert between the two copper springs 507, causing the two copper springs 507 to separate. This causes the high-pressure air pump switch circuit to be cut off, and the high-pressure air pump to stop supplying air. The gas in the air chamber 502 can maintain the air pressure stability in the pneumatic locking mechanism 400, and prevent the locking pin 402 from being released from the locking groove 203 due to partial gas leakage, or even the release of the clamping, causing the two to separate.

[0052] A robotic arm 600 is installed on the connecting plate 202, which can grip objects.

[0053] The inner cavity of the camera housing 301 is also equipped with a storage box 309 for storing calibration accessories and cleaning tools for the 3D camera 308 and the 2D camera 310, which facilitates on-site maintenance. The model of the robotic arm 600 is FZ34-68.

[0054] The on / off mechanism consisting of two copper springs 507 is connected in series with the switch of the high-pressure air pump. Under normal circumstances, the two copper springs 507 are in contact to connect the circuit. When the switch of the high-pressure air pump is also in the open state, the high-pressure air pump works. The high-pressure air pump can also be replaced by a normally closed solenoid valve, so that the check valve 409 is connected to the high-pressure air circuit through the normally closed solenoid valve, which can control whether the high-pressure air in the high-pressure air circuit enters the check valve 409.

[0055] The sealing ring 414 is made of oil-resistant nitrile rubber.

[0056] The specific implementation method is as follows: When the quick-connecting seat 201 mates with the quick-locking platform 102, the clamping component on the quick-locking platform 102 is inserted into the locking groove 203 on the quick-connecting seat 201. During the insertion process, the outer side of the quick-locking platform 102 presses against the movable column 404, causing the movable column 404 to compress the compression spring 406 and enter the closed cylinder 405. During this process, the vent 407 reaches the position of the sealing ring 414, and the vent 407 is covered and sealed by the sealing ring 414. The high-pressure gas in the first air pipe 408 cannot be discharged, and the high-pressure gas in the first air pipe 408 enters the annular airbag 41. 1. The annular airbag 411 is inflated. The annular airbag 411 presses the bottom of the locking post 402 through the outer plate 412. Due to the cooperation between the intermediate cylinder 403 and the limiting cylinder 415, and the restriction of the locking post 402 by the ring 417, the locking post 402 moves horizontally. During the process of the outer plate 412 pressing the locking post 402 to separate, the outer side of the locking post 402 presses the inner wall of the locking groove 203, so that the locking groove 203 locks with the clamping assembly. The bearing structure 100 is locked with the quick assembly mechanism 200 through the clamping assembly. The sealing ring 414 is movably connected to the movable post 404.

[0057] The two copper springs 507 are pressed against each other due to their own elasticity under normal conditions. The separator 506 is made of an insulating material.

[0058] The control switch valve 410 can release the gas in the air pipe 408 and the air pressure maintenance system 500, so that the annular airbag 411 stops squeezing the locking post 402, and the second tension spring 416 returns to its original state. During this period, the second tension spring 416 pulls the limit cylinder 415 and the locking post 402 to move, so that the limit cylinder 415 gathers, the locking block separates from the locking hole, thereby releasing the clamping assembly from locking the locking groove 203 on the quick connector 201, so that the quick connector 201 can be separated from the quick locking table 102.

[0059] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
