DETAILED DESCRIPTION

[0014] 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.

[0015] See also Figure 1-3The utility model provides a tube grinding device for electrical appliances, including a first bottom plate 1 and a second bottom plate 2. The first bottom plate 1 and the second bottom plate 2 are the basis of the grinding device. The first bottom plate 1 and the second bottom plate 2 are connected by a connecting component to ensure the smoothness of adjustment. The connecting component realizes the connection between the first bottom plate 1 and the second bottom plate 2. The front and rear parts of the upper surface of the first bottom plate 1 are fixedly connected with a first bracket 3. The first bracket 3 is loaded with a first motor 7. The operation of the first motor 7 drives the grinding roller 6 to rotate. The grinding roller 6 rotates to grind the tubes for electrical appliances. The top of the rear first bracket 3 is installed with the first motor 7. The output end of the first motor 7 is fixedly connected to the grinding roller 6. The top of the front first bracket 3 is fixedly connected to the first motor 7. There is an insert cylinder 5, which dynamically supports the other end of the grinding roller 6 to ensure the rotation ability of the other end of the grinding roller 6. The grinding roller 6 is inserted into the inside of the insert cylinder 5. One end of the second bracket 9 is fixedly connected to the front of the second bottom plate 2. The second bracket 9 supports the seat cylinder 11. The other end of the second bracket 9 is fixedly connected to the seat cylinder 11. The seat cylinder 11 is equipped with a second motor 12. The rotation of the second motor 12 drives the support assembly to rotate. The support assembly supports the electrical matching pipe. The output end of the second motor 12 is installed inside the seat cylinder 11 and is fixedly connected to a frame 13. Two sliding openings 14 are opened on the frame 13 and are distributed up and down. The sliding opening 14 allows the support assembly to adjust the position, and a support assembly is arranged inside the sliding opening 14.

[0016] Specifically, the support assembly includes a screw 15, which is equipped with a support frame 18. The support frame 8 supports the inner wall of the matching pipe. The screw 15 is inserted into the inside of the sliding mouth 14. A screw barrel 16 is threadedly installed on the outer wall of one side of the screw 15. After the screw barrel 16 is rotated, it is pressed against the frame 13 to fix the screw 15 in the position of the sliding mouth 14. The two support frames 18 move with the screw 15 to adapt to the size of the matching pipe for support. A support frame 18 is fixedly connected to one side of the screw 15.

[0017] Specifically, the connecting component includes an insertion rod 8 and an opening 10. The insertion rod 8 is fixedly connected to the second base plate 2. A support frame 21 is fixedly connected to the inside of the opening 10. A roller 20 is installed on the support frame 21 through a rotating shaft 22. A slide groove 19 is opened on the insertion rod 8. The roller 20 is stuck in the inside of the slide groove 19. When the first base plate 1 moves, the roller 20 is driven to rotate inside the slide groove 19, thereby realizing the limitation of the longitudinal force and ensuring the stability of the movement.

[0018] Specifically, two triggers 17 are fixedly connected to the outer wall of the screw barrel 16 , and the screw barrel 16 can be controlled more conveniently by rotating the triggers 17 .

[0019] Specifically, the support frame 18 is made of plastic, which is soft and can ensure that no damage is caused to the inner wall of the supporting pipe when supporting the supporting pipe.

[0020] Working principle: first place the tube on the outer wall of the support frame 18, and then move the screw 15 to the corresponding position of the slide 14 to adapt the support frame 18 to the size of the inner wall of the matching tube. After adjustment and supporting the matching tube, turn the trigger 17 to drive the screw barrel 16 to rotate. The screw barrel 16 squeezes the frame 13 to fix the screw 15 and also fix the matching tube. At this time, adjust the position between the first bottom plate 1 and the second bottom plate 2 to ensure that the grinding roller 6 can contact the matching tube. At this time, power on the two motors, the first motor 7 drives the grinding roller 6 to rotate, and the second motor 12 drives the matching tube on the frame 13 to rotate for grinding.
