Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1 Please see Figure 1 and Figure 2 This embodiment provides a technical solution: An adjustable pipe processing fixture includes a base 101, a lifting rod 201 with adjustable length mounted on the base 101, a placement plate 301 mounted on the top of the lifting rod 201, and a clamping mechanism mounted on the placement plate 301. The clamping mechanism can fix pipes 1101 of different diameters on the placement plate 301.

[0021] Specifically, in this embodiment, the lifting rod 201 includes a support tube 2011 and a screw 2012, each having a top and a bottom end. The bottom end of the support tube 2011 is connected to the base 101, and the top end of the support tube 2011 is threadedly connected to the bottom end of the screw 2012. The top end of the screw 2012 is rotatably connected to the placement plate 301. Thus, when it is necessary to adjust the support height of this fixing frame, simply rotate the screw 2012.

[0022] To facilitate the placement of pipe 1101 and prevent it from rolling freely after being placed on the placement plate 301, in this embodiment, the placement plate 301 is composed of two integrally formed support plates, which form a V-shaped structure. The top end of the screw 2012 is rotatably connected to the connection point of the two support plates.

[0023] Specifically, to facilitate the installation of the clamping mechanism, an elongated hole (not marked in the figure) is provided on any support plate in this embodiment, and the length direction of the elongated hole is parallel to the length direction of the corresponding support plate. The clamping mechanism consists of two first bolts 401 respectively passing through the two elongated holes. A first nut 402 is threaded onto any first bolt 401. The first nut 402 and the nut of the corresponding first bolt 401 are located on both sides of the corresponding support plate, and the end of any first bolt 401 away from its own nut is located between the two support plates.

[0024] To facilitate the connection between the screw 2012 and the support tube 2011, a second nut 501 is specially installed at the top end of the support tube 2011 in this embodiment. The screw 2012 is threadedly connected to the second nut 501, and the central axis of the screw 2012 and the central axis of the second nut 501 are both collinear with the central axis of the support tube 2011.

[0025] After the height of the placement plate 301 is adjusted by rotating the screw 2012, in order to prevent the screw 2012 from rotating accidentally and affecting the support stability of the fixing frame, a third nut 601 is threadedly connected to the screw 2012 in this embodiment. After the height of the placement plate 301 is adjusted by rotating the screw 2012, the third nut 601 is then tightened until one side of the third nut 601 is tightly abutted against one side of the second nut 501. In this way, the screw 2012 cannot rotate due to the friction between the third nut 601 and the second nut 501, thus ensuring the support stability of the fixing frame.

[0026] To facilitate the movement of this fixed frame, in this embodiment, the base 101 is also equipped with several wheels 701.

[0027] When using this mounting bracket to support the pipe 1101, due to the limited support area of ​​the base 101, in order to further improve the overall stability of the bracket, three support rods 801 are installed on the support pipe 2011 in this embodiment. The three support rods 801 are arranged in a circular array about the central axis of the support pipe 2011. When the bracket is placed on the ground, the free ends of the three support rods 801 abut against the ground. In other embodiments of this embodiment, the number of support rods 801 may be four, five, or more.

[0028] Working principle: like Figure 2As shown, this mounting bracket is generally used in pairs to support the pipe 1101 to be processed. After the pipe 1101 is placed on the mounting plate 301, the two first bolts 401 are moved until the ends of the two first bolts 401 away from their own nuts are in contact with the pipe 1101. Then the two first nuts 402 are tightened until the two first bolts 401 can no longer move in the two elongated holes. At this time, the pipe 1101 is fixed by the mounting plate 301 and the two first bolts 401 to facilitate processing.

[0029] Example 2 Please see Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that: in this embodiment, a groove (not shown in the figure) is provided on any support plate, and the length direction of the groove is parallel to the length direction of the corresponding support plate; a clamping mechanism is installed on any support plate, which includes a slider 901 slidably connected to the corresponding groove, a pressure strip 902 installed on the slider 901, and a second bolt 903 threadedly connected to the support plate, with the pressure strip 902 located between the two support plates; the end of the second bolt 903 away from its nut is slidably connected to the corresponding slider 901, and the sliding direction of the slider 901 and the central axis of the second bolt 903 are both parallel to the length direction of the support plate. Thus, when pipes 1101 of different diameters within a certain size range are placed on the placement plate 301, the two second bolts 903 are tightened to move the two sliders 901 within the two grooves until both pressure strips 902 abut against the pipes 1101, thereby temporarily fixing the pipes 1101 to the placement plate 301.

[0030] After the two pressure strips 902 fix the pipe 1101 to the placement plate 301, the contact points between the two pressure strips 902 and the pipe 1101 are preferably in the same plane. If the contact points between the two pressure strips 902 and the pipe 1101 are not in the same plane, the shear force exerted on the pipe 1101 under the compression of the two pressure strips 902 will cause the pipe 1101 to tend to swing within the placement plate 301, which is not conducive to the fixation of the bracket. Therefore, in order to solve this problem, in this embodiment, the two pressure strips 902 are installed face to face (they are not misaligned). However, when using this bracket to fix the pipe 1101 with a smaller diameter, a new problem arises: when using this bracket to fix the pipe 1101 with a smaller diameter, the two pressure strips 902 installed face to face will interfere with each other during movement, which will prevent them from getting too close, thus making it impossible to fix the pipe 1101 with a smaller diameter to the placement plate 301. Therefore, in order to solve the above problems, this embodiment provides a clearance groove 1001 on one of the pressure strips 902 to allow the other pressure strip 902 to pass through. In this way, when the smaller diameter pipe 1101 is placed on the placement plate 301, as the two pressure strips 902 approach each other, one of the pressure strips 902 will move within the clearance groove 1001 so that they do not interfere with each other's movement.

[0031] Working principle: After the pipe 1101 is placed on the placement plate 301, the two second bolts 903 are screwed on to make the two sliders 901 move in the two grooves respectively until the two pressure strips 902 are in contact with the pipe 1101. In this way, the pipe 1101 can be temporarily fixed on the placement plate 301 for processing.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
