[0042] The reciprocating mechanism is arranged in the mounting shell 8 to fix the other pipe and automatically reciprocate to grind and polish the other pipe end.

[0043] In a specific embodiment of the present utility model, the mounting plate 1 serves as the basic support platform of the entire equipment and is used to fix other components. The fixing plate 2 is used to install the cloth wheel 3 and ensure that the cloth wheel 3 can rotate freely through the rotating shaft. The cloth wheel 3 is used to place the square tube end between the two cloth wheels 3 for grinding and polishing, and grind and polish two surfaces at the same time, thereby improving work efficiency. The placement block 6 is used to install the first motor 7 so that the first motor 7 can run stably. The first motor 7 is used to drive the cloth wheel 3 to rotate. The pulley 4 is used to transmit power through the belt 5. The belt 5 is used to transmit the power of the first motor 7 to the two cloth wheels 3. The mounting shell 8 is used to install and protect other components such as the reciprocating mechanism. The first motor 7, the pulley 4 and the belt 5 drive the first pulley 4 to rotate through the first motor 7. The belt 5 transmits power to the second pulley 4, and then drives the two cloth wheels 3 to rotate to grind and polish the square tube end. This transmission method saves more energy consumption.

[0044] For details, please refer to Figure 1-Figure 4 The reciprocating mechanism includes a fixed block 13, a second motor 9, a threaded rod 10, a limiting rod 11, a slider 12, a rotating groove 14, a rotating block 15 and a limiting assembly. There are six rotating grooves 14 and rotating blocks 15. The fixed block 13 is fixedly connected to the upper end of the mounting plate 1, the second motor 9 is fixedly connected to one side end of the mounting shell 8, the threaded rod 10 is fixedly connected to the output shaft of the second motor 9, the threaded rod 10 is rotatably connected to the adjacent ends of the mounting shell 8 and the fixed block 13, and one end of the limiting rod 11 is fixedly connected to the mounting shell 8. One side end, and the other end of the limit rod 11 is fixedly connected to one side end of the fixed block 13, the slider 12 is slidably connected to the circumferential surface of the threaded rod 10, the slider 12 is slidably connected to the circumferential surface of the limit rod 11, three rotation grooves 14 are all opened in the slider 12, and the other three rotation grooves 14 are all opened in the fixed block 13. The six rotating blocks 15 are rotatably connected to the six rotation grooves 14 respectively. The limiting assembly is provided on the inner wall of one side of the mounting shell 8 to realize limiting when grinding the square tube so that the two cloth wheels 3 only grind and polish the square tube end.

[0045] In this embodiment: the fixed block 13 is used to assist in fixing the square tube so that the square tube will not shake during grinding and affect the accuracy of grinding and polishing. The second motor 9 is used to drive the threaded rod 10 to rotate. The threaded rod 10 is driven and rotated by the second motor 9 to realize the reciprocating linear motion of the slider 12. The limit rod 11 limits the slider 12 so that the slider 12 only moves back and forth along the straight direction. The slider 12 is used to drive the square tube to grind and polish the tube end. The rotating groove 14 is used to install the rotating block 15, which provides a limit for the rotating block 15 so that the rotating block 15 will not shake or fall off when rotating. There is a hole in the rotating block 15. When grinding and polishing, the personnel insert the square tube into the hole so that the square tube will not shake, thereby improving the grinding and polishing. Precision, the personnel inserts the square tube into the hole in the rotating block 15, starts the second motor 9, and the output shaft of the second motor 9 drives the threaded rod 10 to rotate, so that the slider 12 moves along the axial direction of the threaded rod 10. At the same time, the limit rod 11 limits the slider 12 to move back and forth only in a straight line direction. The movement of the slider 12 drives the square tube to move back and forth along the set direction. The two sides of the square tube end are in full contact with the cloth wheel 3 for grinding and polishing. After the grinding and polishing is completed, the second motor 9 is turned off, and the personnel pulls the square tube backward and rotates it. When the square tube rotates, it drives the rotating block 15 to rotate in the rotating groove 14 to turn the square tube over. Then the personnel starts the second motor 9 again to continue grinding and polishing the unpolished surface of the square tube end, thereby improving the work efficiency of the personnel.

[0046] For details, please refer to Figure 1-Figure 4 The limiting assembly includes a T-slot 16 and a T-block 17. There are two T-slots 16 and two T-blocks 17. The two T-slots 16 are respectively opened on the inner wall of one side of the mounting shell 8. The two T-blocks 17 are respectively slidably connected to the two T-slots 16, and the two T-blocks 17 are respectively fixedly connected to the side ends of the slider 12.

[0047] In this embodiment: the T-slot 16 and the T-block 17, through the T-block 17 sliding in the T-slot 16, effectively prevent the slider 12 from shaking and excessive movement during the movement process, thereby ensuring the position stability of the square tube during the grinding and polishing process and preventing the end of the square tube from being excessively ground and polished.

[0048] For details, please refer to Figure 1-Figure 4 A protective shell 18 is fixedly connected to the upper end of the mounting plate 1 .

[0049] In this embodiment, the protective shell 18 effectively prevents iron chips generated when grinding the square tube end from flying out to the outside and affecting the workers, and can prevent external factors from damaging the equipment.

[0050] For details, please refer to Figure 1-Figure 4 The lower end of the mounting plate 1 is fixedly connected to a support 19 , and the lower end of the support 19 is fixedly connected to a gasket 20 .

[0051] In this embodiment, a plurality of pillars 19 and gaskets 20 are provided. The pillars 19 make the device more stable during operation, and the gaskets 20 provide the device with better grip.

[0052] For details, please refer to Figure 1-Figure 4 , the material of the protective shell 18 is stainless steel.

[0053] In this embodiment, the stainless steel material of the protective shell 18 has the characteristics of high strength and smooth surface, which can make it easier for personnel to clean the waste generated during grinding and polishing, and is not easy to deform.

[0054] The working principle and use process of the utility model are as follows: through this device, the personnel starts the first motor 7, the first motor 7 drives the first pulley 4 to rotate, the belt 5 transmits power to the second pulley 4, and then drives the two cloth wheels 3 to rotate, the placement block 6 and the fixed plate 2 ensure the stability of the device during operation, and then the personnel inserts the square tube into the hole of the rotating block 15 in the fixed block 13 and the slider 12, and then starts the second motor 9. The output shaft of the second motor 9 drives the threaded rod 10 to rotate, so that the slider 12 reciprocates linearly on the circumferential surface of the threaded rod 10, and at the same time the limit rod 11 limits the slider 12 to reciprocate only in the linear direction. The movement drives the square tube to perform reciprocating motion, and at the same time, both sides of the square tube end are in full contact with the cloth wheel 3 for grinding and polishing. After the grinding and polishing is completed, the second motor 9 is turned off, and the personnel pulls the square tube backward for rotation. When the square tube rotates, it drives the rotating block 15 to rotate in the rotating groove 14 to turn the square tube over. Then the personnel start the second motor 9 to continue grinding and polishing the unpolished surface of the square tube end, thereby improving the work efficiency of the personnel, and while the slider 12 moves back and forth, the T-block 17 slides in the T-slot 16, effectively preventing the slider 12 from driving the square tube to over-polish the square tube when polishing the tube end, thereby improving the accuracy of the grinding and polishing of the square tube.
