Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a double-tube automatic clamping feeding mechanism. Background Art

[0002] A huge amount of metal tubes are used in the field of power station boilers. For example, the water-cooled wall of the boiler contains a large number of metal tubes. Before the metal tubes are made into water-cooled walls, they need to be cut according to the designed length and the cutting accuracy is high. The cutting accuracy of the tube material is affected by its feeding device.

[0003] At present, the fixed-length feeding mechanism for small-diameter metal tubes is mostly realized by roller rotation as the power and end face positioning. When the tube is cut, it needs to be moved again, which has high equipment operation loss, low positioning accuracy, high operation noise and low processing efficiency. At the same time, when pushing the feeding, the inertia of the tube will cause the tube itself to move forward, resulting in errors in the fixed length, which makes the tube cutting inaccurate. Utility Model Content

[0025] Please refer to Figure 1-Figure 4A double-tube automatic clamping and feeding mechanism includes a clamping device and a detection device, the clamping device includes an L-shaped movable frame 11 and two groups of clamping components fixed on the L-shaped movable frame 11, each group of the clamping components includes a clamping cylinder 13, a movable clamping plate 14, a fixed clamping plate 17 and a plurality of optical axes 16, the cylinder body of the clamping cylinder 13 is fixed to the L-shaped movable frame 11 through a mounting frame 12, the mounting frame 12 and the fixed clamping plate 17 are connected and fixed by a plurality of optical axes 16, the movable clamping plate 14 slides along the optical axis 16, the clamping cylinder 13 controls the sliding of the movable clamping plate 14, the fixed clamping plate 17 is a V-shaped sheet, and the fixed clamping plate 17 cooperates with the movable clamping plate 14 to complete the clamping of the tube material.

[0026] In this embodiment, a linear bearing 15 is fixed on the movable clamping plate 14 , and the movable clamping plate 14 slidably cooperates with the optical axis 16 through the linear bearing 15 . The linear bearing 15 can improve the stability of the movable clamping plate 14 running on the optical axis 16 .

[0027] In this embodiment, the detection device includes a laser sensor, which is fixed to the L-shaped movable frame 11. The laser sensor is used to detect the position state of the pipe material between the movable clamping plate 14 and the fixed clamping plate 17, and the arrival detection of the pipe material is realized by the laser sensor.

[0028] In this embodiment, the V-shaped roller assembly includes a V-shaped groove roller shaft 18, a support seat 19 and a support frame 20. The V-shaped groove roller shaft 18 is rotatably arranged at the top end of the support frame 20. The two ends of the V-shaped groove roller shaft 18 are rotatably connected to the two support seats 19. The support seat 19 is fixed to the support frame 20. The V-shaped groove roller shaft 18 includes two identical V-shaped ring grooves. The distance between the two V-shaped ring grooves is the same as the distance between the two clamping assemblies. The cross-sectional shape of the V-shaped ring groove is the same as the shape of the fixed clamping pressure plate 17.

[0029] In this embodiment, the clamping device is also used to cooperate with the V-shaped roller assembly. When clamping and feeding shorter pipes, the clamping and feeding of the pipes can be completed only by the clamping device. When clamping and feeding longer pipes, a number of evenly arranged V-shaped roller assemblies cooperate with the clamping device. The clamping device achieves precise feeding by clamping the pipes. The V-shaped roller assembly is used to support the longer pipes so that the clamping device is not affected by the gravity of the pipes.

[0030] In this embodiment, the L-shaped movable frame 11 slides on the linear guide rail 21. When the L-shaped movable frame 11 slides on the linear guide rail 21, it drives the clamping assembly to move. The V-groove roller shaft 18 is evenly arranged along the movement direction of the fixed clamping plate 17. When the fixed clamping plate 17 moves, the lower surface of the fixed clamping plate 17 abuts against the V-groove of the V-groove roller shaft 18.

[0031] When in use, the pipe is placed on the V-shaped roller assembly, and the working position of the pipe is positioned by two clamping assemblies and a detection device. The clamping device can be set to run on a guide rail that can be accurately positioned. After the detection device is positioned to the end face of the incoming pipe, the clamping cylinder 13 is activated, and the clamping cylinder 13 pushes the movable clamping plate 14 to slide on the optical axis 16 to clamp one end of the pipe. Two clamping assemblies are arranged on 11, and the workstations where the two clamping assemblies are located are independently detected and operated, which can adapt to relatively complex working conditions.

[0032] When clamping and feeding shorter pipes, the clamping and feeding of the pipes can be completed only by the movable clamping plate 14 and the fixed clamping plate 17. When clamping and feeding longer pipes, the pipes need to be clamped by the movable clamping plate 14 and the fixed clamping plate 17. After the movable clamping plate 14 and the fixed clamping plate 17 clamp the pipes, they are driven to be accurately fed on the V-shaped roller assembly.

[0033] In this embodiment, the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
