[0002] Existing pipe fittings are usually classified into plastic pipe fittings, graphite pipe fittings, metal pipe fittings, etc. according to their materials. Before selling and using metal pipe fittings, a polishing machine is usually used to polish the outer wall of the metal pipe fittings to improve the service life of the pipe fittings. For example, an automatic polishing machine for the outer wall of a metal pipe fitting disclosed in Chinese Patent CN114473766A includes a placement substrate, a traction unit, a polishing unit, and a chute E. A chute E is opened at the rear end of the upper end surface of the placement substrate. A traction unit is installed on the upper end surface of the placement substrate, and a polishing unit is arranged above the traction unit. The polishing unit is installed on the placement substrate. The traction unit includes a material supporting frame, material supporting wheels, a collection block, a traction wheel, a traction frame, a conveyor belt, and a transmission motor. The material supporting frames are symmetrically and evenly installed on the upper end surface of the placement substrate from left to right and front to back. The material supporting wheels are installed on the material supporting frames by means of rotational connection.

[0003] The existing polishing machine needs two sets of motors for driving, that is, one set of motors is used to drive the polishing unit, and the other set of motors drives the traction unit to avoid the problem of low efficiency of manual feeding. For some fine polishing processes, the polishing cutting amount is very small, and the existing polishing machine appears to have an overly complex structure and high energy consumption. Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0022] like Figures 1-4 As shown, a metal tube polishing section driving structure described in the utility model comprises a frame 1, a driving motor 2 and a polishing wheel 3. The frame 1 is provided with a material guide trough 11 and a first bracket 12. The material guide trough 11 is provided with a material tube 13. The first bracket 12 is provided with a rotatable synchronous shaft 14. The polishing wheel 3 is installed on one side of the material guide trough 11 through the synchronous shaft 14, and the polishing wheel 3 touches the material tube 13. The driving motor 2 is fixed on the frame 1. The output shaft of the driving motor 2 is provided with a first pulley 21. The synchronous shaft 14 is provided with a second pulley 22. The first pulley 21 and the second pulley 22 are connected by a belt 23. The material guide trough 11 is provided with an arc-shaped slide groove. The material tube 13 can rotate and slide on the material guide trough 11. The polishing wheel 3 touches the material tube 13. The driving motor 2 drives the polishing wheel 3 to rotate through the synchronous shaft 14. The high-speed rotation of the polishing wheel 3 will generate friction on the material tube 13 to make it rotate synchronously. The polishing wheel 3 polishes the outer surface of the material tube 13. In particular, the surface of the polishing wheel 3 is provided with oblique polishing lines, and when the polishing wheel 3 and the material tube 13 rotate relative to each other, the friction force generated will have an axial component, so that the material tube 13 slides along the material guide groove 11, thereby solving the problem of manual feeding. The utility model has a simple and compact structure, can meet the processing requirements of fine polishing, and reduce energy consumption and production costs.

[0023] The first bracket 12 is provided with a shaft sleeve 15, and the synchronous shaft 14 is rotatably inserted into the shaft sleeve 15. The first end of the synchronous shaft 14 is equipped with a polishing wheel 3, and the second end of the synchronous shaft 14 is provided with a second pulley 22. The synchronous shaft 14 is installed on the bracket 12 through the shaft sleeve 15, and the driving motor 2 drives the synchronous shaft 14 to rotate through the belt 23, the first pulley 21 and the second pulley 22, thereby driving the polishing wheel 3 to rotate to polish the surface of the material tube 13.

[0024] The frame 1 is provided with a base 16, the base 16 is provided with a second bracket 24, and the drive motor 2 is fixedly arranged on the second bracket 24. The base 16 and the second bracket 24 are used to raise the drive motor 2 to prevent the dust generated by polishing from affecting the stable operation of the drive motor 2.

[0025] A chassis 4 is provided on the frame 1. A third support 41 is provided on the chassis 4. A tension pulley 42 is provided on the third support 41.

The chassis 4 is used for installing the adjusting device, and the tightness of the belt 23 is adjusted by the tension pulley 42 on the third support 41 to prevent the belt 23 from slipping and affecting the running stability.

[0026] The adjusting device includes a lifting shaft 43, a slider 44 and an adjusting screw 45. The lifting shaft 43 is vertically movably inserted through the top plate of the chassis 4, and the upper end of the lifting shaft 43 is fixedly connected to the third support 41. The slider 44 is fixedly arranged at the lower end of the lifting shaft 43, and an inclined surface is provided on the slider 44. The adjusting screw 45 is rotatably inserted through the side wall plate of the chassis 4. A knob 46 is provided at the first end of the adjusting screw 45, and a thrust block 47 is provided at the second end of the adjusting screw 45. The thrust block 47 abuts against the inclined surface of the slider 44. Specifically, a screw sleeve is provided between the adjusting screw 45 and the side wall plate of the chassis 4, so that the adjusting screw 45 can move along its axial direction when rotating. The adjusting screw 45 can drive the thrust block 47 to move axially. Cooperating with the inclined surface on the slider 44, the height of the lifting shaft 43 can be adjusted up and down, so as to change the tightness of the belt 23 through the tension pulley 42 and prevent the belt 23 from slipping.

[0027] A spring 48 is sleeved on the lifting shaft 43. The spring 48 abuts between the top plate of the chassis 4 and the slider 44. When the adjusting screw 45 is adjusted in the reverse direction, the lifting shaft 43 and the slider 44 slide down synchronously under the drive of the spring 48.

[0028] Guide rods 49 are provided between the slider 44 and the chassis 4 and between the thrust block 47 and the chassis 4. The guide rods 49 are used to control the movement trajectories of the slider 44 and the thrust block 47. The guide rods 49 and the slider 44 and the thrust block 47 are in clearance fit. Of course, the guide rods 49 can use sliding bearings and other methods to improve the movement flexibility of the slider 44 and the thrust block 47.
