However, the above-mentioned clamping mechanism can only solve the processing of individual pipe fittings and is not applicable to the processing between pipe fittings, such as welding or butt-jointing. Therefore, there are fewer applicable processing scenarios.

[0013] Preferably, the clamping assembly disposed on the sliding bracket has the same configuration as the clamping assembly disposed on the fixed bracket.

[0014] Preferably, the driving mechanism includes a screw rod rotatably mounted on the base at a position below the movable plate and screwed to the movable plate via a ball nut pair, and a driving motor fixedly mounted on the base and with an output shaft connected to one end of the screw rod.

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3A hydrogen pipeline processing clamping mechanism includes a base 1, a moving groove 11 is opened on the top of one end of the base 1, a support assembly 2 is arranged on the top of the other end of the base 1, a moving plate 3 is arranged in the moving groove 11, which moves close to or away from the support assembly 2 and is slidably connected to the base 1, a movable support assembly 31 with the same configuration as the support assembly 2 is arranged on the moving plate 3, a driving mechanism for driving the movable plate 3 to move is arranged on the base 1, a fixed bracket 25 is fixedly connected to the side position of the base 1 corresponding to the support assembly 2, a sliding bracket 34 that moves synchronously with the movable plate 3 is slidably connected to the side position of the base 1 corresponding to the movable support assembly 31, and a clamping assembly is arranged at the upper position of the fixed bracket 25 corresponding to the support assembly 2 and at the upper position of the sliding bracket 34 corresponding to the movable support assembly 31.

[0030] When in use, place the pipe on the support assembly 2 and cooperate with the clamping assembly on the fixed bracket 25 to complete the positioning, and place another pipe on the movable support assembly 31 and cooperate with the clamping assembly on the sliding bracket 34 to complete the positioning, and then drive the movable plate 3 to move through the driving mechanism, so that the movable support assembly 31 on the movable plate 3 drives the pipe on it to approach the pipe on the support assembly 2. Since the sliding bracket 34 is also slidably connected to the base 1, it will move together to ensure that the clamped pipe is stable. The support assembly 2 and the movable support assembly 31 can also be used to position a longer single pipe. It will be more stable if it cooperates with the double clamping assembly above. The position of the support point can also be adjusted according to the length of the pipe through the movable movable plate 3.

[0031] Specifically, the support assembly 2 includes a fixed bracket 21 fixedly installed on the top of one end of the base 1 away from the movable groove 11, a movable bracket 22 slidably connected to the top of the base 1 and moving closer to or away from the fixed bracket 21, and rollers 23 rotatably installed on the top of both ends of the fixed bracket 21 and the movable bracket 22; when the pipe is placed on the support assembly 2, the rollers 23 on the fixed bracket 21 will provide a fixed fulcrum, and then the movable bracket 22 will be slid and adjusted according to the length of the pipe to provide a flexible fulcrum, thereby lifting the pipe more stably.

[0032] In addition, the clamping assembly arranged on the fixed bracket 25 includes a pressure roller seat 26 which moves longitudinally at the upper position of the support assembly 2, pressure rollers 261 which are rotatably installed at the bottom of both ends of the pressure roller seat 26, a hydraulic telescopic rod 27 which is fixedly connected to the fixed bracket 25 and whose movable end is fixedly connected to the pressure roller seat 26, and a positioning rod 28 which is fixedly connected to the four corners of the top of the pressure roller seat 26 and passes through the fixed bracket 25. The positioning rod 28 is slidably connected to the fixed bracket 25. The clamping assembly arranged on the sliding bracket 34 has the same configuration as the clamping assembly arranged on the fixed bracket 25. When the pipe fitting is placed stably, the pressure roller seat 26 is driven downward by the hydraulic telescopic rod 27 until the pressure roller 261 contacts the top of the pipe fitting, thereby cooperating with the support assembly 2 to clamp the pipe fitting. Due to the presence of the four positioning rods 28, the stability of the pressure roller seat 26 is guaranteed. Similarly, the clamping assembly on the rotating motor sliding bracket 34 will also cooperate with the movable support assembly 31 to clamp the pipe fitting in the middle, and can drive the pipe fitting to translate under the drive of the driving mechanism.

[0033] It should be noted that the driving mechanism includes a screw rod 32 rotatably installed on the base 1 at a position below the corresponding movable plate 3 and screwed to the movable plate 3 through a ball nut pair, and a driving motor 33 fixedly installed on the base 1 and with an output shaft connected to one end of the screw rod 32; when it is necessary to move the pipe fittings on the movable support assembly 31, the screw rod 32 is driven to rotate by the driving motor 33, thereby driving the movable plate 3 to move in the movable groove 11 of the base 1 through the ball nut pair under the drive of the screw rod 32, thereby completing the approach or distance between the pipe fittings.

[0034] It can be understood that the upper surface of the movable plate 3 and the upper surface of the base 1 are in the same plane; since the upper surfaces of the movable plate 3 and the base 1 are flush, it is convenient to align the two pipes. Example 2

[0035] Reference Figure 1 The difference between this embodiment and embodiment 1 is that a rotating motor 24 whose output shaft is connected to the rotating shaft of one of the rollers 23 is fixedly installed on the two fixed brackets 21; by arranging a rotating motor 24 connected to the roller 23 on the bracket, the clamped pipe is driven to rotate, thereby saving manpower and making the positioning more stable.

[0036] For other structures not described, refer to Example 1.

[0037] Working principle: in the utility model, when in use, the pipe fitting is placed on the support assembly 2 and the clamping assembly on the fixed bracket 25 is cooperated to complete the positioning, and the other pipe fitting is placed on the movable support assembly 31 and the clamping assembly on the sliding bracket 34 is cooperated to complete the positioning. Specifically, when the pipe fitting is placed on the support assembly 2, the roller 23 on the fixed bracket 21 will provide a fixed fulcrum, and then according to the length of the pipe fitting, the sliding movable bracket 22 is adjusted to provide a flexible fulcrum, so that the pipe fitting can be lifted more stably. When the pipe fitting is placed stably, the pressure roller seat 26 is driven downward by the hydraulic telescopic rod 27 until the pressure roller 261 contacts the top of the pipe fitting, thereby cooperating with the support assembly 2 to clamp the pipe fitting. Due to the presence of four positioning rods 28, the stability of the pressure roller seat 26 is guaranteed. Similarly, the clamping assembly on the rotating motor sliding bracket 34 will also cooperate with the movable support assembly 31 to clamp the middle pipe fitting, and can drive the pipe fitting under the drive of the driving mechanism. The movable plate 3 is driven to move by the driving mechanism, thereby driving the pipe on it to approach the pipe on the supporting assembly 2 through the movable supporting assembly 31 on the movable plate 3. Specifically, the screw rod 32 is driven to rotate by the driving motor 33, thereby driving the movable plate 3 to move in the movable groove 11 of the base 1 under the drive of the screw rod 32 through the ball nut pair, thereby completing the approach or distance between the pipes. Since the sliding bracket 34 is also slidably connected to the base 1, it will move together to ensure the stability of the clamped pipe. The supporting assembly 2 and the movable supporting assembly 31 can also be used to position a longer single pipe. It will be more stable with the double clamping assembly above. The movable movable plate 3 can also be used to adjust the position of the support point according to the length of the pipe. During the processing, the rotating motor 24 connected to the roller 23 can be set on the bracket to drive the clamped pipe to rotate, thereby saving manpower and making the positioning more stable.

[0038] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
