[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] See also Figure 1-4 The utility model provides a technical solution: a clamping device for processing pipe fittings, including a bottom plate 1, fixed blocks 2 are fixedly installed at both ends of the bottom of the bottom plate 1, and screw rods 3 are rotatably installed between the fixed blocks 2. A motor 4 is fixedly installed at one end of the fixed block 2. The output end of the motor 4 passes through the fixed block 2 and is fixedly connected to one end of the screw rod 3. When the motor 4 is running, the screw rod 3 rotates. A movable plate 5 is threadedly sleeved on the surface of the screw rod 3. When the screw rod 3 rotates, the movable plate 5 drives the movable plate 5 to slide. Slide grooves 6 are opened on both sides of the top of the bottom plate 1. Round rods 7 are fixedly installed inside the slide grooves 6. Slide blocks 8 are movably sleeved on the surface of the round rods 7. The outer surface of the slide block 8 and the inner surface of the slide groove 6 are both smooth. The slider 8 can slide more smoothly inside the slide groove 6, reducing the situation of turning on the computer. The slider 8 and the movable plate 5 are both hinged with a movable rod 9. When sliding, the movable rod 9 will drive the slider 8 to move toward or away from the inside of the slide groove 6, and the top of the slider 8 is fixedly installed with a clamping plate 10, which can clamp and fix the pipe fittings. A strip groove 11 is provided on the top of the base plate 1, and a threaded rod 12 is rotatably installed inside the strip groove 11. A sliding sleeve 13 is threadedly sleeved on the surface of the threaded rod 12, and a connecting plate 14 is fixedly installed on the top of the sliding sleeve 13. When the threaded rod 12 rotates, it will drive the sliding sleeve 13 to slide inside the strip groove 11, thereby driving the connecting plate 14 to slide synchronously.

[0021] A turning handle 20 is rotatably mounted on one side of the bottom plate 1, and one side of the turning handle 20 penetrates the bottom plate 1 and is fixedly connected to one side of the threaded rod 12. When the turning handle 20 is rotated, the threaded rod 12 is rotated. A vertical plate 15 is fixedly mounted on the top of the connecting plate 14, and a horizontal plate 16 is fixedly mounted on the top of the vertical plate 15. When the connecting plate 14 slides, it drives the vertical plate 15 and the horizontal plate 16 to slide. Guide rods 17 are movably mounted on both sides of the top of the horizontal plate 16. The bottom of the guide rod 17 penetrates the horizontal plate 16 and extends to the bottom of the horizontal plate 16. A positioning plate 18 is fixedly installed at the bottom of the guide rod 17, and the guide rod 17 can make the positioning plate 18 more stable when pressed down. A pneumatic cylinder 19 is fixedly installed on the top of the cross plate 16, and the output end of the pneumatic cylinder 19 passes through the cross plate 16 and is fixedly connected to the top of the positioning plate 18. The pneumatic cylinder 19 will cause the positioning plate 18 to rise and fall when in operation. Brackets 21 are fixedly installed at the four corners of the bottom of the base plate 1. There are four brackets 21, and the four brackets 21 have the same size. The design of the brackets 21 can make the device more stable.

[0022] Working principle: when it is necessary to clamp the pipe fittings, the operator first places the pipe fittings between the top of the base plate 1 and the clamping plate 10, and then starts the motor 4. The operation of the motor 4 will cause the screw rod 3 to rotate, thereby driving the movable plate 5 to slide on the surface of the motor 4. At this time, the movable plate 5 will drive the movable rod 9 to slide, and at the same time, it will drive the two sliders 8 to move toward each other inside the slide groove 6, thereby driving the clamping plate 10 to clamp and fix the pipe fittings. Secondly, the operator turns the handle 20. The rotation of the handle 20 will cause the threaded rod 12 to rotate, thereby driving the sliding sleeve 13 to slide inside the strip groove 11. At this time, the sliding sleeve 13 will drive the connecting plate 14, the vertical plate 15 and the horizontal plate 16 to slide synchronously. When the positioning plate 18 is placed above the pipe fitting, the pneumatic cylinder 19 is started. The operation of the pneumatic cylinder 19 will drive the guide rod 17 and the positioning plate 18 to rise and fall at the same time until the bottom of the positioning plate 18 reaches the surface of the pipe fitting, so that it can be positioned in the vertical direction.
