Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding chuck used in a special equipment welding workstation. Background Art

[0002] Special equipment refers to equipment that poses a greater risk to personal and property safety, such as boilers, pressure vessels, pressure pipes and elevators. This type of equipment has specific purposes and conditions of use in production, work or life, and has special requirements for its safety and reliability. Once a failure or accident occurs, it may cause serious harm to personal safety, property safety and the environment. In special equipment, it is often necessary to weld cylindrical objects such as pressure pipes.

[0003] During pressure pipe welding operations, the welding chuck is responsible for firmly clamping the pipe so that it can be precisely docked and welded with other equipment. However, when faced with long or heavy pressure pipes, the welding chuck may have difficulty accurately clamping the pipe at its center point. In this case, the clamping force of the chuck may be unevenly distributed, causing the chuck to deform or even damage during the pipe lifting process. Once the clamping force fails, the pressure pipe may accidentally fall off during the lifting process, causing serious safety accidents and posing a huge threat to personnel and equipment. Utility Model Content

[0004] The utility model addresses the deficiencies of the prior art and provides the following technical solutions: a welding chuck for a special equipment welding workstation, comprising a mobile platform, a clamping mechanism for fixing a pressure pipe provided at the bottom of the mobile platform, a stabilizing pressing mechanism provided at the bottom of the mobile platform and located in the middle of the clamping mechanism, the clamping mechanism being movably connected to the stabilizing pressing mechanism;

[0005] The stabilizing pressing mechanism includes a fixed cube, which is movably inserted into one side of the clamping mechanism, a connecting plate is fixedly installed on the left side of the fixed cube, a bracket is fixedly installed in the middle of the bottom of the connecting plate, the bracket is movably hinged with a pneumatic telescopic rod, and the right side of the fixed cube is movably hinged with a swing plate, the telescopic end of the pneumatic telescopic rod is movably hinged to the bottom of the swing plate, and the end of the swing plate away from the fixed cube is movably hinged with a power-assisting plate, and a triangular pressing plate is fixedly installed on the bottom of the power-assisting plate. When the clamping mechanism drives the pressure pipe slowly upward, in order to prevent the pressure pipe from tilting, the tilted pressure pipe is pressed by the stabilizing pressing mechanisms on both sides, so that the pressure pipe is always in a stable state during the process of being clamped and risen by the triangular clamping groove.

[0006] As an improvement of the above technical solution, the clamping mechanism includes a horizontal slot, which is opened at the bottom of the movable platform, and a driving motor is fixedly installed on the front side of the movable platform. The rear end of the driving motor passes through the front inner wall of the horizontal slot and extends into the interior of the driving motor. The output end of the driving motor extending into the interior of the horizontal slot is fixedly installed with a bidirectional threaded rod, and the outer side of the bidirectional threaded rod is connected to a horizontal clamping plate by a thread. The horizontal clamping plate is movably clamped with the horizontal slot, and a movable splint is fixedly installed on the bottom end of the horizontal clamping plate. The fixed square is movably clamped with the movable splint, and a triangular clamping groove is opened on the front side of the movable splint, and the pressure pipe is clamped and fixed by the mutual cooperation between the clamping mechanisms.

[0007] As an improvement to the above technical solution, an arc limit plate is fixedly installed at the bottom of the swing plate near the power-assisting plate to limit the power-assisting plate and prevent it from excessively deflecting downward due to its own gravity.

[0008] As an improvement of the above technical solution, a stabilizing plate is fixedly installed in the middle of the top of the fixed cube, and the top of the stabilizing plate is fixedly installed on the right side of the mobile platform. The fixed cube is fixed by the stabilizing plate to prevent the moving clamps on both sides from moving due to friction during the movement process.

[0009] As an improvement of the above technical solution, there are two groups of stable pressing mechanisms, and another group of stable pressing mechanisms is set at the bottom of the mobile platform near the left side, and the two sides of the pressure pipe are pressed and fixed by the stable pressing mechanisms on both sides.

[0010] The beneficial effects of the present invention are as follows: when the clamping mechanism drives the pressure pipe to slowly rise, in order to prevent the pressure pipe from tilting, the tilted pressure pipe is pressed by the stable pressing mechanisms on both sides, so that the pressure pipe is always in a stable state during the process of being clamped and raised by the triangular clamping groove. The cooperation between the clamping mechanism and the stable pressing mechanism shows a high degree of reliability and safety of the pressure pipe during its rise, which greatly reduces the probability of safety accidents, provides sufficient protection for personnel and equipment, and ensures the safety and smooth progress of the operation process.

[0019] Specifically, a welding chuck for a special equipment welding workstation includes a mobile platform 1, a clamping mechanism for fixing a pressure pipe is provided at the bottom of the mobile platform 1, a stabilizing pressing mechanism is provided at the bottom of the mobile platform 1 and in the middle of the clamping mechanism, and the clamping mechanism and the stabilizing pressing mechanism are movably connected;

[0020] The stable pressing mechanism includes a fixed cube 3, which is movably inserted into one side of the clamping mechanism. A connecting plate 31 is fixedly installed on the left side of the fixed cube 3, and a bracket is fixedly installed in the middle of the bottom of the connecting plate 31. The bracket is movably hinged with a pneumatic telescopic rod 32. The right side of the fixed cube 3 is movably hinged with a swing plate 33. The telescopic end of the pneumatic telescopic rod 32 is movably hinged to the bottom of the swing plate 33. The end of the swing plate 33 away from the fixed cube 3 is movably hinged with a power-assisting plate 34, and a triangular pressing plate 35 is fixedly installed at the bottom of the power-assisting plate 34.

[0021] In this embodiment, when the clamping mechanism drives the pressure pipe slowly upward, in order to prevent the pressure pipe from tilting, the tilted pressure pipe is pressed by the stable pressing mechanisms on both sides, so that the pressure pipe is always in a stable state during the process of being clamped and raised by the triangular clamping groove 25.

[0022] Specifically, the clamping mechanism includes a horizontal slot 2, which is opened at the bottom of the mobile platform 1. A driving motor 21 is fixedly installed on the front side of the mobile platform 1. The rear end of the driving motor 21 passes through the front inner wall of the horizontal slot 2 and extends into the interior of the driving motor 21. The output end of the driving motor 21 extending into the interior of the horizontal slot 2 is fixedly installed with a bidirectional threaded rod 22. The outer side of the bidirectional threaded rod 22 is connected to a horizontal clamping plate 23 through a thread. The horizontal clamping plate 23 is movably clamped with the horizontal slot 2. A movable splint 24 is fixedly installed on the bottom end of the horizontal clamping plate 23. The fixed square body 3 is movably clamped with the movable splint 24. A triangular clamping groove 25 is opened on the front side of the movable splint 24.

[0023] In this embodiment, the pressure pipe is clamped and fixed by the mutual cooperation between the clamping mechanisms.

[0024] Specifically, an arc limit plate is fixedly installed at the bottom of the swing plate 33 near the power plate 34.

[0025] In this embodiment, the assisting plate 34 is restricted to prevent the assisting plate 34 from excessively deflecting downward due to its own gravity.

[0026] Specifically, a stabilizing plate is fixedly installed in the middle of the top of the fixed cube 3 , and the top of the stabilizing plate is fixedly installed to the right side of the mobile platform 1 .

[0027] In this embodiment, the fixed cube 3 is fixed by the stabilizing plate to prevent the movable clamping plates 24 on both sides from driving the fixed cube 3 to move due to friction during the movement process.

[0028] Specifically, there are two groups of stable pressing mechanisms, and another group of stable pressing mechanisms is provided at the bottom of the mobile platform 1 near the left side.

[0029] In this embodiment, the two sides of the pressure pipe are pressed and fixed by the stable pressing mechanisms on both sides.

[0030] When in use, the external power equipment is connected through the connecting cylinder on the top of the mobile platform 1, and the external power equipment drives the mobile platform 1 to move to the triangular clamping grooves 25 on both sides close to the middle position of the pressure pipe. When the external power equipment drives the mobile platform 1 to move downward to clamp the pressure pipe, the mobile platform 1 moves the triangular clamping grooves 25 on both sides to both sides of the pressure pipe through the cooperation of structures such as the horizontal clamping plates 23, and starts the driving motor 21. The driving motor 21 drives the bidirectional threaded rod 22 to rotate. When the bidirectional threaded rod 22 rotates, it drives the horizontal clamping plates 23 on both sides to move to the middle position of the bidirectional threaded rod 22 under the restriction of the horizontal clamping grooves 2. The horizontal clamping plates 23 on both sides drive the moving clamping plates 24 on both sides to move close to the position of the pressure pipe. The moving clamping plates 24 on both sides drive the triangular clamping grooves 25 on both sides to move to clamp the pressure pipe. When the triangular clamping grooves 25 on both sides complete the clamping of the pressure pipe, the external power equipment uses the horizontal clamping plates 23 and other structures The cooperation of the two makes the triangular clamping grooves 25 on both sides drive the pressure pipe to move slowly upward. At this time, if the pressure pipe tilts lower on the left side during the upward movement, the pneumatic telescopic rod 32 contracts and drives the swing plate 33 to swing downward with the hinge with the fixed square body 3 as the fulcrum, and the swing plate 33 drives the power-assisting plate 34 to swing downward, and the power-assisting plate 34 drives the triangular pressing plate 35 to move downward to press the pressure pipe that is tilted on the right side. Similarly, when the pressure pipe tilts lower on the right side during the upward movement, the working principle is the same as above, so that the triangular clamping groove 25 drives the pressure pipe to move upward in a stable state, which is convenient for the pressure pipe to be accurately docked and welded with other equipment. The cooperation of the clamping mechanism and the stable pressing mechanism shows that the pressure pipe has high reliability and safety when rising, greatly reducing the probability of safety accidents, providing sufficient protection for personnel and equipment, and ensuring the safety and smooth progress of the operation process.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
