[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] like Figure 1-Figure 5 As shown, the utility model proposes a convenient clamping device for fixing pipes, including a clamping mechanism. The clamping mechanism includes a base 1, on which two clamping parts 2 are slidably arranged, and the two clamping parts 2 are symmetrically arranged at both ends of the length direction of the base 1; an adjustment component 3 is arranged between the two clamping parts 2, and the adjustment component 3 can adjust the two clamping parts 2 to move away from or close to each other, so that the two clamping parts 2 clamp the pipe 7 or loosen the pipe 7. Each clamping part 2 is provided with a clamping head 20, which is a long strip structure, and the length direction of the clamping head 20 is perpendicular to the length direction of the base 1. One end of the clamping head 20 extends in a direction away from the base 1, and the side of the two clamping heads 20 that is close to each other is set as an arc 22, that is, the inner side of the clamping head 20 is an arc; the other side opposite to it is also an arc 22, that is, the outer side of the clamping head 20 is also an arc.

[0024] Specifically, Figure 1-Figure 3As shown, the clamping part 2 also includes a clamping rod 21, the clamping rod 21 is U-shaped, and the clamping head 20 is fixedly arranged on the side wall of one side of the clamping rod 21. A support 25 is fixedly arranged on the side wall of one side of the clamping rod 21, and the clamping head 20 is fixed on the support 25. In addition, one side of the clamping rod 21 where the clamping head 20 is arranged is located above the base 1, and the other side thereof is located below the base 1. Figure 1 As shown, a slide 10 is provided on the upper surface of the base 1, and the slide 10 is fixedly arranged along the length direction of the base 1; the adjustment component 3 is arranged below the base 1; the end of the clamping rod 21 located on the upper side of the base 1 is provided with a slide groove 23 that cooperates with the slide 10; and the clamping rod 21 is located on the lower side of the base 1 and is connected with the adjustment component 3.

[0025] like Figure 2 and Figure 3 As shown, the adjustment assembly 3 includes a bidirectional threaded rod 30 and a power part that drives the bidirectional threaded rod 30 to rotate. The two ends of the base 1 in the length direction are respectively provided with fixed seats 11, and the two ends of the bidirectional threaded rod 30 are respectively rotatably connected to the two fixed seats 11; the two sides of the length direction of the bidirectional threaded rod 30 are respectively provided with threads in opposite directions, and the two clamping parts 2 are respectively located on the two sides of the bidirectional threaded rod 30, and the corresponding ends of the clamping rod 21 corresponding to each clamping part 2 are respectively threadedly connected to the two sides of the bidirectional threaded rod 30. Among them, the end of each clamping rod 21 on one side below the base 1 is fixedly provided with a threaded sleeve 24 threadedly connected to the bidirectional threaded rod 30, as shown in FIG. Figure 2 As shown, the threaded sleeve 24 is sleeved on the bidirectional threaded rod 30 and threadedly connected thereto.

[0026] like Figure 3 As shown, the power unit includes a stepper motor 31, two transmission wheels 32 and a transmission belt 33, wherein the center of one transmission wheel 32 is fixedly arranged at the middle of the bidirectional threaded rod 30, and the axial direction of the transmission wheel 32 is parallel to the axial direction of the bidirectional threaded rod 30. The center of the other transmission wheel 32 is fixedly arranged on the motor shaft of the stepper motor 31, and the transmission belts 33 are respectively sleeved on the outside of the two transmission wheels 32.

[0027] In the present application, a bottom plate 4 is provided below the base 1, and the bottom plate 4 is fixedly connected to the bottom of the fixing seat 11; the adjustment assembly 3 is arranged between the base 1 and the bottom plate 4, and the stepper motor 31 is fixed on the bottom plate 4. In addition, an outer cover 5 is provided on one side of the base 1, and the outer cover 5 is arranged between the base 1 and the bottom plate 4, and the stepper motor 31 is covered inside the outer cover 5 to prevent the stepper motor 31 from being damaged.

[0028] In practical applications, the clamping mechanism of the present application can be provided with two at the same time, and the two clamping mechanisms are symmetrically arranged. And for the convenience of operation, a support seat 6 can be provided at the same time, wherein Figure 4As shown, the support seat 6 can be placed in front of each clamping mechanism, and the support seat 6 is directly opposite to the center between the two clamping heads 20. When it is necessary to clamp and fix the pipe 7, the pipe 7 can be placed on the support seat 6 first, as shown in FIG. Figure 4 As shown, the end of the pipe 7 extends between the two clamping heads 20, and then the stepper motor 31 is controlled to start, and the stepper motor 31 drives the bidirectional threaded rod 30 to rotate through the transmission wheel 32 and the transmission belt 33. When the bidirectional threaded rod 30 rotates, since the threads on both sides of the bidirectional threaded rod 30 are in opposite directions, and the two clamping parts 2 are respectively threadedly connected with the two sides of the bidirectional threaded rod 30, and since the clamping rod 21 is slidably connected with the slideway 10, the slideway 10 limits the clamping rod 21 to only perform linear displacement, therefore, the two clamping parts 2 can simultaneously move toward the middle, thereby clamping the pipe 7. When it is necessary to loosen the pipe 7, the stepper motor 31 is started to make the motor shaft of the stepper motor 31 rotate in the opposite direction, so that the two clamping heads 20 can move away from each other, and the pipe 7 is loosened.

[0029] The side of the two clamping heads 20 close to each other is set as an arc 22, that is, the inner sides of the two clamping heads 20 are both arc 22, which can match the arc outer wall of the pipe 7 to make the clamping more stable. In addition, the stepper motors 31 in the two clamping mechanisms in the present application can be controlled by the same control switch at the same time, that is, the two stepper motors 31 are connected to the same control switch, and the control switch can start the two stepper motors 31 at the same time, so that the two clamping mechanisms are clamped or released at the same time, which is convenient for control.

[0030] In addition, the clamping mechanism in the present application also has another implementation mode. For certain operations on the pipe 7, such as when spraying is required on the outside of the pipe 7, if the above-mentioned clamping and fixing method is used, the two ends of the pipe 7 will be covered by the clamping head 20, so that the part cannot be sprayed. At this time, another implementation mode of the present application can be used, that is, first start the stepper motor 31 to make the two clamping heads 20 on each clamping mechanism close to each other and minimize the distance between them. Then place the pipe 7 on the support seat 6, and make the two ends of the pipe 7 respectively cover the outside of the two clamping heads 20 in each clamping mechanism, that is, the ends of the two clamping heads 20 in each clamping mechanism that extend away from the base 1 extend into the interior of the pipe 7. Then start the stepper motor 31 again to make the motor shaft of the stepper motor 31 rotate in the opposite direction, and drive the bidirectional threaded rod 30 to rotate through the power unit, so that the two clamping rods 21 move away from each other until the outer sides of the two clamping heads 20, that is, the sides that are away from each other, are pressed against the inner wall of the pipe 7, as shown in FIG. Figure 5 As shown, the pipe 7 is clamped and fixed. The side of the two clamping heads 20 in the present application that is away from each other, that is, the outer side of the clamping head 20 is also arc-shaped 22, which can match the arc-shaped inner wall of the pipe 7 to make the clamping more stable.

[0031] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments 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.
