DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following is combined with the attachedFigures 1-4 A further detailed description of the present application will be given.

[0019] An embodiment of the present application discloses a flat processing device for machining parts. Referring to Figure 1 and Figure 3 , it includes a second support plate 4. A rotating ring 15 is movably arranged inside the second support plate 4. Circular rings 12 are fixedly arranged on both end faces of the rotating ring 15. The two circular rings 12 are respectively movably connected to the front and back of the second support plate 4. Four support plates 19 are fixedly arranged on the opposite sides of the two circular rings 12. The four support plates 19 are equidistantly distributed in a circumferential shape. A threaded rod 20 is inserted through each support plate 19. The threaded rod 20 is threadedly connected to the support plate 19. One end of the threaded rod 20 is fixedly connected to a rotating plate 13. The other end of the threaded rod 20 is fixedly connected to a support 17 through a bearing. A roller 18 is fixedly arranged inside the support 17. By rotating the rotating plate 13, the rotation of the rotating plate 13 drives the threaded rod 20 to move towards the center of the circular ring 12. The movement of the threaded rod 20 drives the support 17 and the roller 18 to move. Through the arrangement of eight rollers 18, square tubes of different sizes can be clamped and fixed, preventing the square tube from moving when the grinding disc 3 grinds and levels the end face of the square tube subsequently, thereby affecting the grinding and leveling accuracy of the end face of the square tube.

[0020] Referring to Figures 2-4 , a collar 14 is fixedly sleeved on the outer wall of the rotating ring 15. Through holes 6 are provided through both side walls of the second support plate 4. A roller 7 is movably arranged inside the through hole 6. The roller 7 is slidably connected to the collar 14. A shaft rod 16 is fixedly inserted through the roller 7. Both ends of the shaft rod 16 are rotatably connected to a connecting plate 11. One end of one of the shaft rods 16 penetrates through the connecting plate 11 and extends outward to be fixedly sleeved with a pulley 8. The pulley 8 is connected to another pulley 8 through a belt. The output end of a second motor 9 is inserted through the other pulley 8. The second motor 9 is connected to the second support plate 4 by screws. Fixed blocks 21 are fixedly arranged on both the inner top wall and the inner bottom wall of the second support plate 4. Arc-shaped grooves 22 are provided on the opposite side walls of the two fixed blocks 21. The arc-shaped grooves 22 are slidably connected to the collar 14. By driving the pulley 8 on it to rotate through the output end of the second motor 9, the rotation of the pulley 8 drives another pulley 8 to rotate through the belt. The rotation of the other pulley 8 drives the shaft rod 16 on it to rotate. The rotation of the shaft rod 16 drives the roller 7 on it to rotate. The rotation of the roller 7 drives the collar 14, the rotating ring 15 and the circular ring 12 to rotate. At the same time, the cooperation of the other roller 7 and the two arc-shaped grooves 22 increases the stability of the rotation of the roller 7. The rotation of the circular ring 12 drives the square tube to rotate through the roller 18. The cooperation between the rotation of the square tube and the grinding disc 3 greatly improves the grinding and leveling speed of the end face of the square tube.

[0021] Referring to Figure 1, a bottom plate 5 is fixedly provided on the bottom surface of the second support plate 4. One end of the top surface of the bottom plate 5 is fixedly provided with a first support plate 2. A first motor 1 is detachably provided on the side wall of the first support plate 2 opposite to the second support plate 4 through screws. The output end of the first motor 1 penetrates through the first support plate 2 and extends outward to be connected with a grinding disc 3. The grinding disc 3 is driven to rotate by the output end of the first motor 1, and the rotation of the grinding disc 3 realizes the grinding operation on the end face of the square tube.

[0022] The implementation principle of a flat processing device for mechanical parts in an embodiment of the present application is as follows: During use, by rotating the rotating plate 13, the rotation of the rotating plate 13 drives the threaded rod 20 to move towards the center of the ring 12. The movement of the threaded rod 20 drives the bracket 17 and the roller 18 to move. Through the arrangement of eight rollers 18, square tubes of different sizes can be clamped and fixed. At the same time, another pulley 8 is driven to rotate through a belt. The rotation of another pulley 8 drives the shaft rod 16 thereon to rotate. The rotation of the shaft rod 16 drives the roller 7 thereon to rotate. The rotation of the roller 7 drives the collar 14, the rotating ring 15 and the ring 12 to rotate. At the same time, another roller 7 cooperates with two arc-shaped grooves 22 to increase the stability of the rotation of the roller 7. The rotation of the ring 12 drives the square tube to rotate through the roller 18, and the output end of the first motor 1 drives the grinding disc 3 to rotate. The rotation of the grinding disc 3 realizes the grinding operation on the end face of the square tube.
