Description

Technical Field

[0001] The utility model relates to the technical field of jigs, and more specifically, to a clamping tool for filter plug welding. Background Art

[0002] For filter plug welding, manual flame welding is adopted, and electrodes are manually added and penetrate from the outside to the inside. The penetration is poor, resulting in a large accumulation of external welding and some blocked holes being concave. Now the welding method is changed to high-frequency welding, and the filter plug passes through a heating coil for welding. Existing tooling jigs can usually only hold one piece. After welding is completed, the welded filter plug needs to be removed and a new one needs to be installed, so there is a waiting time in the middle, resulting in low overall welding efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a clamping tool for filter plug welding.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses a clamping tool for filter plug welding, which includes a support frame. A tray is rotatably arranged on the support frame, and an installation frame is installed on the tray. A fixing piece is installed at each end of the installation frame. A support column is connected to the middle position of the upper part of the tray, and the installation frame is sleeved on the support column. The support frame includes a base, and an installation cavity is opened inside the base. A driving motor is arranged in the installation cavity, and the driving motor is drivingly connected to the tray.

[0006] Furthermore, the installation frame includes two fixing blocks, and the two fixing blocks are connected by a second fixing bolt.

[0007] Furthermore, the fixing block includes an arc-shaped block, and the inner wall of the arc-shaped block is arranged to fit the outer wall of the support column. A connecting block and a support plate are respectively connected to both ends of the arc-shaped block. The fixing piece is installed on the support plate, and the connecting block in one fixing block is in contact with the support plate in the other fixing block.

[0008] Furthermore, a first through hole is opened on the connecting block, and a second through hole is opened on the support plate. The second fixing bolt passes through the first through hole and the second through hole.

[0009] Furthermore, a notch and a positioning hole are opened on the support plate. The notch and the positioning hole penetrate the front and rear side walls of the support plate. The notch is communicated with the positioning hole, and the notch is communicated with the end of the support plate. A first fixing bolt is arranged on the support plate, and the first fixing bolt passes through the notch. The fixing piece includes a fixing rod, and the fixing rod passes through the positioning hole.

[0010] Furthermore, the fixing member includes a support block which is connected to the fixing rod. An installation ring is connected to one end of the support block away from the fixing rod.

Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Such as Figures 1-4As shown in the figure, a clamping tooling for filter plug welding includes an installation table 4. A support frame 1 is connected to the installation table 4. A tray 5 is rotatably arranged on the support frame 1. An installation frame 2 is installed on the tray 5. A fixing member 3 is installed at each of the left and right ends of the installation frame 2. The two fixing members 3 are used alternately and do not affect each other. When one fixing member 3 clamps the filter pipe for welding, the other fixing member 3 can be used for loading and unloading the filter pipe, thereby improving the overall welding efficiency.

[0019] A support column 6 is connected to the middle position of the upper part of the tray 5. The installation frame 2 is sleeved on the support column 6. The support column 6 is perpendicular to the tray 5. The support frame 1 includes a base 20. An installation cavity 21 is formed inside the base 20. A driving motor 23 is arranged in the installation cavity 21. The driving motor 23 is drivingly connected to the tray 5. The driving motor 23 can drive the tray 5 to rotate, thereby driving the installation frame 2 to rotate to adjust the position of the fixing member 3.

[0020] Furthermore, the installation frame 2 includes two fixing blocks 7. The two fixing blocks 7 are connected by a second fixing bolt 27. The two fixing blocks 7 are spliced to form the installation frame 2. The fixing block 7 includes an arc-shaped block 8. The inner wall of the arc-shaped block 8 is attached to the outer wall of the support column 6. Connecting blocks 9 and support plates 10 are respectively connected to both ends of the arc-shaped block 8. The fixing member 3 is installed on the support plate 10. The two fixing blocks 7 are arranged staggeredly. The connecting block 9 in one fixing block 7 is in contact with the support plate 10 in the other fixing block 7. A first through hole 11 is formed in the connecting block 9, and a second through hole 12 is formed in the support plate 10. When the two fixing blocks 7 are spliced with the support column 6 as the center, the second through hole 12 in one fixing block 7 corresponds to the first through hole 11 in the other fixing block 7 in the front and back. The second fixing bolt 27 is passed through the first through hole 11 and the second through hole 12 to fix the two fixing blocks 7.

[0021] Furthermore, a notch 25 and a positioning hole 24 are formed in the support plate 10. The notch 25 and the positioning hole 24 penetrate through the front and back side walls of the support plate 10. The notch 25 is communicated with the positioning hole 24. The notch 25 is communicated with the end of the support plate 10. A first fixing bolt 26 is arranged on the support plate 10. The first fixing bolt 26 is passed through the notch 25.

[0022] The fixing member 3 includes a fixing rod 14 and a support block 13. The support block 13 is connected to the fixing rod 14. An installation ring 15 is connected to the end of the support block 13 away from the fixing rod 14. The fixing rod 14 is inserted into the positioning hole 24. By tightening the first fixing bolt 26, the notch 25 is compressed to clamp the fixing rod 14 in the positioning hole 24, thereby completing the fixing of the fixing member 3.

[0023] A threaded seat 18 is provided on the outer periphery of the mounting ring 15. A screw rod 17 is connected to the threaded seat 18 by internal threads. The inner end of the screw rod 17 extends into the mounting ring 15 and is rotatably connected to a pressing block 16. The pressing block 16 is arc-shaped. The outer end of the screw rod 17 passes through the threaded seat 18 and is connected to a handle 19. By rotating the screw rod 17, the pressing block 16 moves towards the inner side of the mounting ring 15, and the pressing block 16 can cooperate with the inner wall of the mounting ring 15 to clamp the filter tube. With this structure, it can be applicable to filter tubes within a certain diameter range.

[0024] Furthermore, a hydraulic cylinder 22 is provided in the installation cavity 21. The upper end of the piston rod of the hydraulic cylinder 22 is connected to the bottom of the drive motor 23. By controlling the telescopic movement of the piston rod by the hydraulic cylinder 22, the height of the drive motor 23 is changed, thereby adjusting the height of the tray 5, so that the filter tube clamped on the fixing member 3 can enter the heating coil at a lower height or leave the heating coil at a higher height.

[0025] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments.
