[0002] Metals are usually made of metal materials such as stainless steel, carbon steel, copper, aluminum, etc., and have good corrosion resistance and wear resistance, and can adapt to different environments and media. During the production process of metal pipe fittings, mechanical fixtures are required for limiting treatment. Metal materials include pipe fittings, and during the production process of metal pipe fittings, clamps are used to clamp them. At present, most of the fixtures position the pipe fittings through arc-shaped plates and clamping blocks. However, most of the fixtures do not have a limiting structure, making it difficult to clamp metal pipe fittings of different specifications, resulting in the phenomenon that the metal pipe fittings are prone to looseness during processing, and subsequent damage to the metal pipe fittings is likely to occur. Summary of the Utility Model

[0003] In order to overcome the above defects, the utility model provides a mechanical fixture for metal processing, which solves the problems that most of the fixtures do not have a limiting structure, making it difficult to clamp metal pipe fittings of different specifications, resulting in the phenomenon that the metal pipe fittings are prone to looseness during processing, and subsequent damage to the metal pipe fittings is likely to occur.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A mechanical fixture for metal processing, including a base, on which a metal pipe body is lapped. A first motor and a sleeve plate are connected to the base. An auxiliary plate is connected to the base. Three clamping plates are arranged outside the auxiliary plate. A fixing rod is connected to the base. A connecting plate is slidably connected to the outside of the fixing rod. The clamping plates are lapped outside the metal pipe body. One end of the first motor is connected to a rotating rod, and one end of the rotating rod is connected to a turntable. A cross plate is connected under the clamping plate. An arc-shaped groove is formed in the turntable. A limiting rod is connected to one side of the cross plate, and the limiting rod is slidably connected in the arc-shaped groove.

[0006] As a further scheme of the utility model: A fixing block is connected to the outside of the base, and a threaded rod is rotatably connected in the fixing block.

[0007] As a further scheme of the utility model: A second motor is connected under the threaded rod, and a connecting frame is connected to the connecting plate.

[0008] As a further scheme of the utility model: A moving plate is connected to one side of the connecting frame, and the moving plate is threadedly connected to the outside of the threaded rod.

[0009] As a further solution of the present utility model: the bridging plate is lapped outside the metal pipe body, and the second motor is connected under the fixed block.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. For the mechanical fixture for metal processing, by setting the clamping plate, the first motor, the rotating rod, the turntable, the cross plate, the arc-shaped groove and the limiting rod, after the metal pipe body is lapped above the base, the turntable is driven to rotate by the first motor. When the rotating rod rotates, the limiting rod will slide in the arc-shaped groove, and when the limiting rod slides, it will drive the cross plate to move in the auxiliary plate, so that the three clamping plates can expand on the surface of the auxiliary plate. Through the cooperation between the turntable, the arc-shaped groove and the limiting rod, the clamping plate of this fixture can realize the adjustment function, which is convenient for clamping metal pipe bodies of different specifications, avoiding the phenomenon of loosening of the metal pipe body during the processing process, and preventing the position of the metal pipe body from shifting during processing and causing damage to the surface.

[0018] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0019] AsFigures 1-4 As shown in the figure, the utility model provides a technical solution: a mechanical fixture for metal processing, including a base 1, on which a metal pipe body 5 is lapped. A first motor 9 and a sleeve plate 10 are connected to the base 1. An auxiliary plate 7 is connected to the base 1. There are three clamping plates 8 outside the auxiliary plate 7. A fixing rod 2 is connected to the base 1. A lapping plate 3 is slidably connected outside the fixing rod 2. The clamping plates 8 are lapped outside the metal pipe body 5. By setting the lapping plate 3, when the lapping plate 3 slides on the surface of the fixing rod 2, the lapping plate 3 is lapped on the surface of the metal pipe body 5, which can play a certain supporting role at both ends of the metal pipe body 5, avoiding the metal pipe body 5 from shifting or falling off during processing;

[0020] A fixing block 4 is connected outside the base 1. A threaded rod 11 is rotatably connected inside the fixing block 4. A second motor 13 is connected below the threaded rod 11. A connecting frame 6 is connected to the lapping plate 3. A moving plate 12 is connected to one side of the connecting frame 6. The moving plate 12 is threadedly connected outside the threaded rod 11. The lapping plate 3 is lapped outside the metal pipe body 5. The second motor 13 is connected below the fixing block 4. By setting the fixing rod 2, when the moving plate 12 moves, it will exert a thrust or a pull force on the lapping plate 3, and the lapping plate 3 will move on the surface of the fixing rod 2, so that the fixing rod 2 plays a certain guiding role in the movement of the lapping plate 3, avoiding the lapping plate 3 from jamming during movement;

[0021] One end of the first motor 9 is connected to a rotating rod 14. One end of the rotating rod 14 is connected to a turntable 15. A cross plate 16 is connected below the clamping plate 8. An arc groove 17 is opened inside the turntable 15. A limiting rod 18 is connected to one side of the cross plate 16. The limiting rod 18 is slidably connected inside the arc groove 17. By setting the auxiliary plate 7, when the cross plate 16 is affected by a thrust or a pull force, the cross plate 16 will drive the clamping plate 8 to slide inside the auxiliary plate 7, so that the auxiliary plate 7 plays a certain auxiliary role in the movement of the cross plate 16, avoiding the cross plate 16 from being knocked during movement;

[0022] The cross plate 16 is slidably connected inside the auxiliary plate 7. The rotating rod 14 is rotatably connected inside the sleeve plate 10. By setting the arc groove 17, when the turntable 15 rotates, the limiting rod 18 on the side of the cross plate 16 will slide inside the arc groove 17, and the cross plate 16 will move accordingly, so that the arc groove 17 can adjust the moving distance of the cross plate 16, avoiding the cross plate 16 from being misaligned during movement.

[0023] The working principle of the utility model is as follows:

[0024] When the fixture clamps a metal pipe fitting, the metal pipe body 5 can be lapped above the base 1. Then, the first motor 9 drives the turntable 15 to rotate around the rotating rod 14. When the rotating rod 14 rotates, the limiting rod 18 will slide in the arc-shaped groove 17. When the limiting rod 18 slides, it will drive the cross-shaped plate 16 to move in the auxiliary plate 7, so that the three clamping plates 8 can expand on the surface of the auxiliary plate 7. Then, the three clamping plates 8 can limit one end of the metal pipe body 5. After the limiting process of the metal pipe body 5 is completed, the second motor 13 drives the threaded rod 11 to rotate, and the moving plate 12 will move on the surface of the threaded rod 11. Since the moving plate 12 is connected to the overlapping plate 3 through the connecting frame 6, the overlapping plate 3 will slide on the surface of the fixed rod 2. After the overlapping plate 3 moves, it will overlap on the surface of the metal pipe body 5.
