Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figure 1-4 In this embodiment: a tool for processing office desk and chair tubing includes a base 1, a fixed frame 2 fixedly connected to one side of the upper surface of the base 1, a connecting frame 3 installed on the other side of the upper surface of the base 1, a rotating cylinder 4 rotatably connected to the upper part of the fixed frame 2, a motor 5 fixedly connected to the inner wall of the rotating cylinder 4, a screw 6 fixedly connected to the output end of the motor 5, a fixed cylinder 7 fixedly connected to the middle of one side of the rotating cylinder 4, the outer wall of the screw 6 rotatably connected to the inner wall of the fixed cylinder 7, a threaded sleeve 8 threadedly connected to one side of the outer wall of the screw 6, fixed rings 9 fixedly connected to both sides of the outer wall of the fixed cylinder 7, a connecting ring 10 provided on the outer wall of the threaded sleeve 8, a fixed plate 11 fixedly connected to the outer walls of the fixed rings 9 and the connecting rings 10 in the circumferential direction, a pull plate 12 rotatably connected to the surface of the fixed plate 11, a connecting plate 13 installed on the inner side of the pull plate 12, a positioning frame 14 fixedly connected to one side of the outer wall of the connecting plate 13, a stop rod 15 installed on the upper part of the connecting frame 3, and a grinding component 16 installed on one side of the outer wall of the base 1;

[0021] In this embodiment, at the start of operation, the pipe to be processed is placed on the positioning frame 14. Then, the control motor 5 drives the internal screw 6 to rotate, causing the threaded sleeve 8 to move axially. When the threaded sleeve 8 moves, it can drive the connecting ring 10 connected to it to move synchronously, which in turn drives the fixing plate 11 to move. The fixing plate 11 drives the pull plate 12 to move, and the pull plate 12 pushes the connecting plate 13. Thus, the connecting plate 13 drives the pull plate 12 connected to the outer wall of the fixing ring 9 to move synchronously. The connecting plate 13 drives the positioning frame 14 to clamp the pipe. Then, the abutment 15 is pressed into the inner wall of the other end of the pipe, and the grinding assembly 16 is started to grind the pipe, so that the pipe can be fully ground to ensure processing accuracy.

[0022] Furthermore, a motor 17 is fixedly connected to the upper part of one side of the outer wall of the fixed frame 2, and the output end of the motor 17 is fixedly connected to one end of the rotating drum 4. An I-beam 18 is fixedly connected to one side of the abutment rod 15, and the middle part of the outer wall of the I-beam 18 is rotatably connected to the upper part of the connecting frame 3.

[0023] During the grinding of the pipe, the motor 17 is started, which drives the rotating drum 4 to rotate, thereby driving the entire positioning structure to rotate. The pipe is clamped in the positioning structure and rotates accordingly. The abutment 15 drives the I-beam 18 to rotate on the connecting frame 3, thus realizing the preparation for 360° grinding of the outer wall of the pipe.

[0024] Furthermore, a groove 23 is provided on the other side of the upper surface of the base 1, and a slider 21 is fixedly connected to the lower surface of the connecting frame 3. The outer wall of the slider 21 is slidably connected to the inner wall of the groove 23. A motor 3 19 is fixedly connected to one side of the base 1. A rotating shaft 1 20 is fixedly connected to the output end of the motor 3 19. One end of the rotating shaft 1 20 is rotatably connected to one side of the inner wall of the groove 23. Guide rods 22 are fixedly connected to both sides of the inside of the groove 23. The middle part of the slider 21 is threadedly connected to the outer wall of the rotating shaft 1 20, and the inner sides of the slider 21 are slidably connected to the outer wall of the guide rod 22.

[0025] In this process, by starting motor 319, the rotating shaft 20 is driven to rotate, and the slider 21 is driven to move along the guide rod 22 in the slide groove 23 through the thread, thereby realizing the forward and backward translation of the connecting frame 3, and adjusting the position of the abutment rod 15 according to the position of the pipe.

[0026] Furthermore, a support frame 24 is fixedly connected to one side of the outer wall of the base 1, a motor 25 is fixedly connected to one side of the outer wall of the support frame 24, a rotating shaft 26 is fixedly connected to the output end of the motor 25, one end of the rotating shaft 26 is rotatably connected to the inner side of the support frame 24, and the grinding assembly 16 is installed on the outer wall of the rotating shaft 26.

[0027] Among them, the starting motor 25 drives the rotating shaft 26 to rotate, which in turn drives the grinding assembly 16 to move.

[0028] Furthermore, the grinding assembly 16 includes a mounting bracket 1601, the lower part of which is threaded to the outer wall of the rotating shaft 26, the upper part of which is fixedly connected to an electric telescopic rod 1602, the output end of which is fixedly connected to a mounting plate 1603, and a grinder 1604 fixedly connected to one side of the mounting plate 1603.

[0029] The installation plate 1603 can be moved by activating the electric telescopic rod 1602, which in turn drives the grinder 1604 to extend and retract back and forth, so that it presses against the pipe, and then the grinder 1604 is activated to grind the surface of the pipe.

[0030] Preferably, a guide block 27 is fixedly connected to the lower part of one side of the outer wall of the mounting bracket 1601, and a guide groove 28 is provided on one side of the outer wall of the base 1. The outer wall of the guide block 27 is slidably connected to the inner wall of the guide groove 28.

[0031] When the mounting bracket 1601 moves, the guide block 27 slides on the inner wall of the guide groove 28, thereby ensuring the linear movement of the mounting bracket 1601.

[0032] The working principle and usage process of this utility model are as follows: At the start of operation, the pipe to be processed is placed on the positioning frame 14. Then, the control motor 5 drives the internal screw 6 to rotate, causing the threaded sleeve 8 to move axially. As the sleeve 8 moves, it drives the connecting ring 10 connected to it to move synchronously, which in turn drives the fixing plate 11 to move. The fixing plate 11 then drives the pull plate 12 to move, causing the pull plate 12 to push the connecting plate 13. This allows the connecting plate 13 to drive the pull plate 12 connected to the outer wall of the fixing ring 9 to move synchronously. The connecting plate 13 drives the positioning frame 14 to clamp the pipe. Then, the starting motor 19 drives the rotating shaft 20 to rotate, which drives the slider 21 to move along the guide rod 22 in the slide groove 23 via the thread, realizing the forward and backward translation of the connecting frame 3, thereby adjusting the pipe... The position of the support rod 15 is adjusted so that it abuts against the inner wall of the other end of the pipe. The electric telescopic rod 1602 is activated to control the movement of the mounting plate 1603, which in turn drives the grinder 1604 to extend and retract back and forth, so that it abuts against the pipe. Then the grinder 1604 is activated to grind the surface of the pipe. At the same time, motors 27 and 425 are activated. Motor 425 drives the rotating shaft 26 to rotate, which drives the mounting frame 1601 to move. Motor 217 drives the rotating drum 4 to rotate, which in turn drives the entire positioning structure to rotate. The pipe is clamped in the positioning structure and therefore rotates as well. The support rod 15 drives the I-beam 18 to rotate on the connecting frame 3, so that the grinder 1604 can perform 360° grinding on the outer wall of the pipe.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
