Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] Example

[0021] See Figures 1 to 4 The auxiliary support structure for the grooving machine tube in this embodiment includes a rotating support plate assembly 1, a support plate assembly 2, a support base assembly 3, two sets of universal bearing support base assemblies 4, two universal bearing support base fixing plates 5, a linear guide rail 6, several universal balls 7, a lead screw 10, a first rotating swing arm pair 12, two lead screw pair fixing blocks 13, a hydraulic cylinder assembly 15, a second rotating swing arm pair 16, two lower pulleys 17, two upper pulleys 18, a motor 20, a slider 21, two lower pulley tracks 22, and two upper pulley tracks.

[0022] In this embodiment, the first rotating arm assembly 12 has a U-shaped structure, and the second rotating arm assembly 16 has an H-shaped structure. The middle parts of the first rotating arm assembly 12 and the second rotating arm assembly 16 intersect and are hinged. Normally, the middle parts of the first rotating arm assembly 12 and the second rotating arm assembly 16 are hinged through the first rotating shaft 9. The upper part of the first rotating arm assembly 12 is hinged to the bottom surface of the support plate assembly 2. Two lower rollers 17 are installed on the lower part of the first rotating arm assembly 12, and two lower roller tracks 22 are fixed on the support base assembly 3. The two lower rollers 17 are respectively located on the two lower roller tracks 22.

[0023] In this embodiment, the lower part of the second rotating arm assembly 16 is hinged to the support base assembly 3, and two upper pulleys 18 are installed on the upper part of the second rotating arm assembly 16. Two upper pulley tracks are fixed to the bottom surface of the support plate assembly 2, and the two upper pulleys 18 are respectively located on the two upper pulley tracks.

[0024] In this embodiment, one end of the hydraulic cylinder assembly 15 is hinged to the lower part of the first rotary swing arm 12, and the other end of the hydraulic cylinder assembly 15 is hinged to the middle part of the second rotary swing arm 16. The motor 20 is fixed to the middle part of the second rotary swing arm 16 and is connected to the hydraulic cylinder assembly 15. Normally, one end of the hydraulic cylinder assembly 15 is hinged to the lower part of the first rotary swing arm 12 via the second rotating shaft 14.

[0025] In this embodiment, several omnidirectional balls 7 are mounted on the top surface of the support plate assembly 2. Typically, the omnidirectional balls 7 are mounted on the top surface of the support plate assembly 2 using hexagonal head screws 8. The rotating support plate assembly 1 rests on the omnidirectional balls 7, and the linear guide rails 6 are fixed to the top surface of the rotating support plate assembly 1. Slider blocks 21 are fixed to the bottom surfaces of the two universal bearing support base fixing plates 5, and the sliders 21 are connected to the linear guide rails 6. Typically, there are four linear guide rails 6, and the four linear guide rails 6 are parallel to each other.

[0026] In this embodiment, the two lead screw fixing blocks 13 are respectively fixed on the bottom surface of the two universal bearing support base fixing plates 5. The two lead screw fixing blocks 13 are threadedly connected to the lead screw 10. The threads in the threaded holes on the two lead screw fixing blocks 13 have opposite directions. The lead screw 10 and the linear guide 6 are parallel.

[0027] In this embodiment, the two sets of universal bearing support assemblies 4 are respectively installed on the top surfaces of the two universal bearing support fixing plates 5, and an area for accommodating and supporting the pipe being processed is formed between the two sets of universal bearing support assemblies 4. Normally, the two sets of universal bearing support assemblies 4 are installed on the two universal bearing support fixing plates 5 respectively by hexagon socket head cap screws 11.

[0028] The auxiliary support structure for the grooving machine tube in this embodiment may also include a remote control handle 19, which is connected to a motor 20. The support plate assembly 2 is provided with a vertical rotating shaft, and the rotating support plate assembly 1 is rotatably connected to the rotating shaft of the support plate assembly 2, allowing the rotating support plate assembly 1 to rotate on the support plate assembly 2. Each end of the rotating support plate assembly 1 is provided with a positioning hole 23, and one end of the support plate assembly 2 may be provided with a positioning push-pull rod 24. This positioning push-pull rod 24 engages with the positioning hole 23 in the rotating support plate assembly 1. When the rotating support plate assembly 1 rotates to its designated position on the support plate assembly 2, the positioning push-pull rod 24 in the support plate assembly 2 inserts into one of the positioning holes 23 in the rotating support plate assembly 1, thereby positioning the rotating support plate assembly 1.

[0029] The motor 20 is controlled by the remote control handle 19 to rotate, which in turn drives the hydraulic cylinder assembly 15 to work. The hydraulic cylinder assembly 15 pushes the support plate assembly 2 to rise and fall, thereby achieving the raising and lowering of the rotating support plate assembly 1. The universal bearing support seat assembly 4 is positioned close to the outer wall of the pipe being processed. Below the support plate assembly 2, there are two interlocking and hinged rotating swing arm pairs 12 and 16. During the raising and lowering process, the upper pulley 18 and lower pulley 17 slide on the pulley tracks of the support plate assembly 2 and support seat assembly 3, respectively, making the entire movement more stable. Below the rotating support plate assembly 1 is a universal ball 7, and the support plate assembly 2 is equipped with a positioning push-pull rod 24. By rotating the rotating support plate assembly 1, the positions of the two ends of the rotating support plate assembly 1 can be interchanged, meaning the rotating support plate assembly 1 can rotate 180° to achieve the function of grooving the two axial ends of the pipe one by one. The rotating support plate assembly 1 is provided with a positioning hole 23, which cooperates with the positioning push-pull rod 24 on the support plate assembly 2. When the rotating support plate assembly 1 is rotated into position, it can be positioned by inserting the positioning push-pull rod 24 into one of the positioning holes 23. The threaded holes on the two lead screw pair fixing blocks 13 have opposite directions of rotation. By rotating the lead screw 10 to drive the lead screw pair fixing blocks 13 to move, the horizontal movement of the universal bearing support seat assembly 1 can be realized, making pipe installation more convenient.
