The clamping device can fix the workpiece tightly on the workbench, and the supporting device can provide the necessary support force to ensure that the workpiece does not move or loosen during processing. The existing auxiliary fixtures for hardware pipe processing are used to clamp pipes in a single way, and cannot clamp pipes of different shapes, such as the positioning of the pipe mouth between curved pipes and the positioning between curved pipes and straight pipes. This results in poor flexibility and practicality of the fixture, and the fixture needs to be replaced for adjustment. Utility Model Content

[0015] 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.

[0016] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0017] Reference Figure 1-Figure 6 According to an embodiment of the utility model, a pipe fixing fixture comprises a clamping platform 10, wherein the left and right ends of the clamping platform 10 are provided with storage grooves 11, and the upper end surface of the clamping platform 10 is provided with two left-right symmetrical lower abutment plates 14, and the upper end of the clamping platform 10 is provided with two front-to-back symmetrical sliding cavities 13, and each sliding cavity 13 is rotatably connected with two left-to-right symmetrical threaded rods 15, and a power source is provided in the clamping platform 10 and is connected to the threaded rod 15 for power connection, and a threaded slider is fixed at the lower end of the lower abutment plate 14 and is threadedly matched with the threaded rod 15, and two left-to-right symmetrical fixing frames 16 and a rotating wheel 21 are rotatably connected on the front and rear end surfaces of the clamping platform 10, and threaded grooves 25 corresponding to the front and back of the rotating wheel 21 are provided on the clamping platform 10, and each threaded groove 25 is threadedly connected A fixing rod 19 is connected, and each fixing rod 19 is provided with an anti-skid pad 20 near the end of the rotating wheel 21. A slide groove is opened in each fixing frame 16, and a rack 17 is fixedly embedded on the side wall of the slide groove. A gear 18 is fixed on the rotating wheel 21 to mesh with the rack 17. A bidirectional screw 22 is rotatably connected between the two adjacent fixing frames 16 in front and behind. The thread rotation directions on the two extended ends of the bidirectional screw 22 are oppositely arranged. Two front and rear symmetrical abutment blocks 23 are threadedly connected on the outer periphery of the two bidirectional screws 22. The abutment blocks 23 are slidably matched with the guide sliding connection frame 24. The two lower abutment plates 14 are provided with an inclined end and a horizontal end. The front end of the clamping table 10 is provided with two left and right distributed control buttons 12, and the two control buttons 12 can be electrically connected to the power source in the clamping table 10;

[0018] The pipe is prevented from being on the clamping platform 10 by the two lower abutment plates 14 distributed on the left and right. When the horizontal end of the lower abutment plate 14 is located directly below the guide sliding connecting frame 24, the fixing rod 19 is rotated to make the fixing rod 19 move away from the clamping platform 10 end through the threaded cooperation with the thread groove 25, and the anti-skid pad 20 is disengaged from the abutment between the rotating wheel 21, so that the rotating wheel 21 can rotate. The user drives the gear 18 fixedly connected to the rotating wheel 21 to rotate by rotating the rotating wheel 21. Under the meshing of the gear 18 and the rack 17, the fixing frame 16 set on the front and rear end surfaces of the clamping platform 10 is controlled to slide up and down, and the inclination angle of the fixing frame 16 can be changed to make the fixing frame 16 tilt to the left or right. The fixing frame 16 moves downward, and synchronously drives the fixedly connected guide sliding connecting frame 24 to slide downward, so that the bidirectional screw 22 approaches the pipe part, and the bidirectional screw 22 is rotated to make The two abutment blocks 23 threadedly connected on the bidirectional screw 22 move forward and backward through the sliding connection with the guide sliding connecting frame 24, and the two abutment blocks 23 approach each other to the middle end portion of the bidirectional screw 22. As the fixing frame 16 slides downward, the abutment blocks 23 on the bidirectional screw 22 can abut against the front and rear ends of the pipe. After the two abutment blocks 23 abut against the front and rear ends of the pipe part, the user rotates the fixing rod 19 in the opposite direction to make the fixing rod 19 slide toward the end close to the clamping platform 10, and the anti-skid pad 20 on the fixing rod 19 abuts against the rotating wheel 21 again. The abutment between the anti-skid pad 20 and the rotating wheel 21 limits the rotation of the rotating wheel 21, thereby locking the fixing frame 16 and the abutment blocks 23 through the meshing and locking at the gear 18 and the rack 17. The upper end portion of the pipe is clamped by the abutment blocks 23 at the left and right ends, and the lower end portion of the pipe abuts against the lower abutment plate 14, and is clamped up and down;

[0019] The movement of the lower abutment plate 14 works through the threaded rod 15, and the threaded rod 15 is driven by the power source set in the clamping table 10. During the rotation of the threaded rod 15, the threaded sliding blocks connected by threads at the left and right ends are driven to slide left and right in the sliding cavity 13, so that the two lower abutment plates 14 distributed on the left and right are moved away from or close to each other, and the position of the lower abutment plates 14 is changed, so that the pipe is abutted against the inclined surface and horizontal surface of the lower abutment plates 14. The operation of the power source is determined by the two control buttons 12 set on the left and right. For example, pressing the control button 12 on the left side causes the power source to drive the lower abutment plate 14 on the left side to move to the left, and pressing it again drives the lower abutment plate 14 on the left side to move to the right. Similarly, the position of the lower abutment plate 14 on the right side is controlled by the control button 12 on the right side.

[0020] When storing, the fixing rod 19 is rotated to allow the rotating wheel 21 to rotate, and the fixing frames 16 on the left and right sides are flipped back to the storage groove 11 by pushing the fixing frames 16, and the fixing frames 16 on the left and right sides are brought closer to each other by rotating the rotating wheel 21, and the abutment block 23 is stored in the storage groove 11.

[0021] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
