[0002] Pipe end forming machines are processing and forming equipment used for flaring, shrinking, and reducing pipe fittings under normal conditions. They are controlled by an integrated touch screen display. Pipe end forming machines are widely used for processing and forming connection parts of pipe fittings, automotive oil pipes, water pipes, air conditioning pipes, etc. They are ideal pipe end forming processing equipment and are suitable for processing complex pipe end shapes. With the development of the times and technology, pipe end forming machines have gradually become one of the most important pieces of equipment in pipe production at present. Various auxiliary equipment derived from them have also been greatly promoted and developed. The most obvious example is the front positioning device, which assists the forming machine in positioning the pipe and can effectively improve the working efficiency of the forming machine.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0027] Example:

[0028] A front positioning device for a pipe end forming machine includes a fixed base 1 and a pipe fitting. A transmission box 2 is fixedly connected to the fixed base 1. A fixed cover 22 is fixedly connected inside the transmission box 2. A slide rod 23 is fixedly connected between the fixed cover 22 and the transmission box 2. An outer extrusion plate 21 is movably connected to the slide rod 23. Two first clamping blocks 211 are fixedly connected to one end of the outer extrusion plate 21. A central positioning column 3 is fixedly connected to the front end of the transmission box 2. A positioning seat 4 is fixedly connected to the front end of the central positioning column 3. An inner extrusion rod 41 is rotatably connected to the positioning seat 4. A second clamping block 43 is fixedly connected to one end of the inner extrusion rod 41. A movable arm 42 is rotatably connected to the inner extrusion rod 41. A camera 5 is fixedly connected to the front end of the positioning seat 4. The device also includes:

[0029] The first power mechanism is used to drive the outer extrusion plate 21 to be clamped to the outside of the tube;

[0030] The second power mechanism is used to drive the second clamping block 43 to press inside the tube.

[0031] By adopting the above technical solution, when using the device, it is first inserted into the pipe. During insertion, the camera 5 fixed on the positioning seat 4 can monitor and observe the pipe. Then, the second clamping block 43 is driven by the second power mechanism to squeeze the pipe from the inside out. Then, the first clamping block 211 on the outer extrusion plate 21 is driven by the first power mechanism to squeeze the outside of the pipe. The first clamping block 211 and the second clamping block 43 can be clamped at three points. At the same time, there are four sets of the first clamping block 211 and the second clamping block 43, which can clamp and fix the pipe and have a stable effect.

[0032] Specifically, the first power mechanism includes a first servo motor 25 and a lead screw 24. The first servo motor 25 is fixedly connected inside the transmission box 2. The output shaft of the first servo motor 25 is fixedly connected to a second helical gear 251. The lead screw 24 is rotatably connected to the fixed cover 22. The first helical gear 241 fixed at one end of the lead screw 24 meshes with the second helical gear 251.

[0033] The transmission box 2 has a first limiting port 26, and the outer extrusion plate 21 passes through the first limiting port 26 and is movably connected to the transmission box 2. The outer extrusion plate 21 is threadedly engaged with the lead screw 24.

[0034] By adopting the above technical solution, the first power mechanism can drive the first clamping block 211 to squeeze and clamp the outside of the pipe fitting. That is, the first servo motor 25 is turned on to drive the second helical gear 251 to rotate, the second helical gear 251 drives the meshing first helical gear 241 to rotate, and the first helical gear 241 drives the lead screw 24 to rotate. Since the outer extrusion plate 21 passes through the first limiting port 26 and is threadedly engaged with the lead screw 24, and the outer extrusion plate 21 slides at the upper limit of the slide rod 23, the rotating lead screw 24 can drive the outer extrusion plate 21 to move. The moved outer extrusion plate 21 pushes the first clamping block 211 to clamp the pipe fitting.

[0035] Specifically, the second power mechanism includes a second servo motor 32, which is fixedly connected inside the transmission box 2. The output shaft of the second servo motor 32 is fixedly connected to a screw 33, and one end of the screw 33 is movably connected to a movable seat 34, with the screw 33 and the movable seat 34 threadedly engaged.

[0036] The outer surface of the central positioning post 3 is provided with a second limiting port 31, and the movable seat 34 passes through the second limiting port 31 and is movablely engaged with the central positioning post 3.

[0037] One end of the movable arm 42 is rotatably connected to the movable seat 34.

[0038] By adopting the above technical solution, the second power mechanism can drive the second clamping block 43 to press and fix the pipe from the inside out. That is, by turning on the second servo motor 32, the screw 33 can be rotated. Since the movable seat 34 is threadedly engaged with the screw 33, the movable seat 34 passes through the second limit port 31 and moves at the upper limit of the central positioning post 3. Since the movable arm 42 rotates on the movable seat 34, and the other end of the movable arm 42 rotates on the inner pressing rod 41, and one end of the inner pressing rod 41 rotates on the positioning seat 4, the movable seat 34 pushes the movable arm 42 and the inner pressing rod 41 to rotate, thereby driving the second clamping block 43 to move. The moved second clamping block 43 can press the inside of the pipe.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
