[0003] The current positioning fixtures for thin-walled pipes usually only clamp the outer wall of the thin-walled pipes when in use. The fixing effect is unstable, and the subsequent pipes are prone to deformation, which is inconvenient to use. In addition, the existing fixtures are difficult to adapt to pipes of different sizes and have poor practicality. Utility Model Content

An external clamping block is fixedly installed on the side wall where the two moving rods are close to each other, and a first servo motor is fixedly installed on the outer wall of the hollow base.

[0008] Preferably, the internal support mechanism includes a second servo motor fixedly mounted on the inner wall of one end of the fixed cylinder away from the movable groove, the output shaft of the second servo motor is fixedly connected to a one-way threaded rod, a threaded block is threadedly sleeved on the outer wall of the one-way threaded rod, four outriggers slidably connected to the fixed cylinder are provided through the four outriggers, one end of the connecting rod is rotatably connected to the side wall of the four outriggers close to the threaded block, the other ends of the four connecting rods are rotatably connected to the threaded block, one end of the four outriggers is fixedly mounted with an internal support block located outside the fixed cylinder, four sliding grooves are opened on the inner wall of one end of the fixed cylinder, and a slider is fixedly mounted on one side wall of the four outriggers.

[0009] Preferably, the two outer clamping blocks and the four inner supporting blocks are all arc-shaped.

[0010] Preferably, one end of the bidirectional threaded rod passes through the inner wall of one end of the hollow base and is fixedly connected to the output shaft of the first servo motor.

[0011] Preferably, the four sliding blocks are slidably connected to the four sliding grooves respectively.

[0012] Beneficial effects of the utility model:

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figures 1-4, a positioning fixture for anti-deformation thin-walled pipe fittings, including a hollow base 1, a fixed plate 8 is fixedly installed on the top of the hollow base 1, and a fixed cylinder 6 fixedly connected to it is penetrated on the fixed plate 8, a movable groove 3 is opened on the top of the hollow base 1, and an external clamping mechanism is provided on the hollow base 1, the external clamping mechanism includes a bidirectional threaded rod 9 rotatably connected between the inner walls on both sides of the hollow base 1, and two symmetrically arranged moving rods 4 are threadedly sleeved on the outer wall of the bidirectional threaded rod 9, the two moving rods 4 both penetrate the moving groove 3 and fit with the inner wall of the moving groove 3, and an external clamping block 5 is fixedly installed on the side wall where the two moving rods 4 are close to each other, and a first servo motor 2 is fixedly installed on the outer wall of the hollow base 1, and one end of the bidirectional threaded rod 9 penetrates the inner wall of one end of the hollow base 1 and is fixedly connected to the output shaft of the first servo motor 2;

[0021] The fixed cylinder 6 is provided with an internal support mechanism, which includes a second servo motor 10 fixedly mounted on the inner wall of the fixed cylinder 6 away from the movable groove 3. The output shaft of the second servo motor 10 is fixedly connected to a one-way threaded rod 11, and a threaded block 12 is threadedly sleeved on the outer wall of the one-way threaded rod 11. Four outriggers 14 slidably connected to it are provided through the fixed cylinder 6. One end of the four outriggers 14 is rotatably connected to a connecting rod 13 on one side wall close to the threaded block 12, and the other ends of the four connecting rods 13 are rotatably connected to the threaded block 12. One end of the four outriggers 14 is fixedly mounted with an internal support block 7 located outside the fixed cylinder 6. Four sliding grooves 16 are provided on the inner wall of one end of the fixed cylinder 6. A slider 15 is fixedly mounted on one side wall of the four outriggers 14. The two outer clamping blocks 5 and the four inner support blocks 7 are all arc-shaped, and the four sliders 15 are slidably connected to the four sliding grooves 16 respectively.

[0022] When the utility model is used, the pipe fitting is put on the fixed cylinder 6, and the bidirectional threaded rod 9 can be rotated by starting the first servo motor 2. During the rotation of the bidirectional threaded rod 9, the moving rod 4 is in contact with the inner wall of the moving groove 3 and will not rotate, so that the two moving rods 4 can be moved closer to or away from each other, and then the two outer clamping blocks 5 can be moved closer to or away from each other. The two outer clamping blocks 5 that are close to each other can clamp and fix the outer wall of the pipe fitting. By starting the second servo motor 10, the unidirectional threaded rod 11 is rotated. During the rotation of the unidirectional threaded rod 11, the four connecting rods 13 prevent the thread block 12 from rotating, so that The threaded block 12 is moved away from the second servo motor 10 or close to the second servo motor 10. When the threaded block 12 is away from the second servo motor 10, the four sliders 15 can slide in the four slide grooves 16 respectively through the rotation of the four connecting rods 13, and then the four outriggers 14 and the four inner support blocks 7 can be extended outward, so that the inner wall of the pipe fitting can be pressed and fixed. By fixing the outer wall and the inner wall at the same time, the fixing effect can be effectively improved, and the deformation of the pipe fitting can be effectively avoided. By controlling the moving distance of the two outer clamping blocks 5 and the outrigger distance of the four inner support blocks 7, pipe fittings of different sizes can be fixed, which is convenient to use.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
