A rubber energy-absorbing pad 20 is fixedly arranged at the bottom end of the base 1.

[0027] Working principle: In order to enable the fixing fixture used in the production of plastic products to fix and clamp plastic pipes of different sizes and diameters and increase the practicality of the fixing equipment, the staff first puts the plastic pipe to be processed on the first arc-shaped fixing plate 8, and then starts the first servo motor 4 and the second servo motor 11 through the controller 19. The first screw 3 and the second screw 10 rotate at the same time to move the first arc-shaped fixing plate 8 and the second arc-shaped fixing plate 15 to clamp and fix the inside of the plastic pipe. When the touch switch 18 contacts the inner wall of the plastic pipe, the touch switch 18 sends a signal to the controller 19, and the controller 19 controls the first servo motor 4 and the second servo motor 11 to be turned off to prevent deformation of the plastic pipe caused by excessive clamping. At the same time, the rubber pad 17 improves the contact with the plastic. The friction force of the inner wall of the pipe ensures the stability of the fixation. When the inner wall of the plastic pipe does not need to be fixed and the outer wall needs to be fixed according to different operational requirements, the same method as above is used, except that the plastic pipe needs to be placed between the third arc-shaped fixing plate 16. The fixing method is the same and will not be repeated here. After the plastic pipe is fixed, vibration may occur when the staff processes it. At this time, the rubber energy-absorbing pad 20 arranged directly under the base 1 absorbs the vibration and improves the processing quality. Through the cooperation of the first screw 3, the first arc-shaped fixing plate 8, the second screw 10, the second arc-shaped fixing plate 15, and the third arc-shaped fixing plate 16, plastic pipes of different sizes can be fixed and clamped on the inner wall, thereby improving the scope of application of the equipment.
