[0023] The embodiment is given by Figures 1-5 The present utility model discloses a metal pipe fitting grinding device, including a base 1, a turntable 2 and a fixing frame 5. A servo motor is fixedly installed inside the base 1. The output end of the servo motor penetrates the inner wall of the base 1 and is fixedly connected to the turntable 2. The top of the base 1 is fixedly connected to the fixing frame 5. A chute 4 is opened on the inner wall of the turntable 2. A grinding assembly 3 is movably connected inside the chute 4. A threaded rod 6 is threadedly connected to the side wall of the fixing frame 5. The end of the threaded rod 6 is movably connected to a clamping block 7 for clamping the metal pipe fitting;

[0024] The grinding assembly 3 includes a slider 31, a connecting groove 32, a bidirectional threaded rod 33, a grinding ball 34, a connecting block 35 and a clamping block 36. A clamping groove 9 is opened on the inner wall of the turntable 2 inside the chute 4. The slider 31 is slidably connected inside the chute 4. A clamping block 36 is fixedly connected to the outside of the slider 31. A connecting groove 32 is opened on the inner wall of the slider 31. Two groups of grinding balls 34 are slidably connected inside the connecting groove 32. A bidirectional threaded rod 33 is rotatably connected to the inner wall of the slider 31. A connecting block 35 is fixedly connected to the outside of the slider 31;

[0025] Specifically, the clamping block 36 is located inside the clamping groove 9 and can slide along the clamping groove 9;

[0026] Specifically, the connecting block 35 is attached to the surface of the turntable 2. A threaded hole 8 is opened on the inner wall of the turntable 2. A screw is movably inserted into the inner wall of the connecting block 35. The screw is threadedly connected to the threaded hole 8 for fixing the connecting block 35;

[0027] Specifically, the bidirectional threaded rod 33 is embedded in the inner side of the connection groove 32 and is threadedly connected to the two grinding balls 34. When the bidirectional threaded rod 33 rotates clockwise, the two grinding balls 34 can be driven to approach each other, and when the bidirectional threaded rod 33 rotates counterclockwise, the two grinding balls 34 can be driven to move away from each other;

[0028] Specifically, through holes are provided at the corresponding positions of the inner wall of the turntable 2 where the bidirectional threaded rod 33 is located.

[0029] Working principle: During use, the cut metal pipe fitting is inserted into the inner side of the fixing frame 5, and by rotating the threaded rod 6, the movement of the clamping block 7 is pushed to clamp the metal pipe fitting;

[0030] The staff rotates the bidirectional threaded rod 33 to make the two grinding balls 34 approach or move away from each other, thereby adjusting the distance between the two grinding balls 34 to adapt to the thickness of the pipe fitting. Subsequently, the cut metal pipe fitting can be moved between the two grinding balls 34, and the two grinding balls 34 are made to abut against the inner and outer walls of the metal pipe fitting. Then, the servo motor can be driven to drive the rotation of the turntable 2, so that the grinding balls 34 rotate along the inner and outer walls of the metal pipe fitting, thereby grinding the inner and outer walls of the metal pipe fitting, and then removing the burrs on the inner and outer walls of the metal pipe fitting. It is possible to simultaneously grind the burrs on the inner and outer walls of the metal pipe fitting, eliminate the limitations of the grinding device, avoid replacing the grinding device, save time and effort, reduce the working process of grinding the metal pipe fitting, and improve the processing efficiency of the metal pipe fitting.

[0031] Meanwhile, through the connection of the connecting block 35, the screw in the threaded hole 8 can be taken out, so that the slider 31 moves in the chute 4, and then the position of the connecting block 35 on the turntable 2 can be adjusted, and then the position adjustment of the slider 31 in the chute 4 can be realized. By connecting the screw and the threaded hole 8 again, the fixing of the slider 31 can be realized, so as to adapt to the grinding of metal pipe fittings with different diameters and is convenient for adjustment.

[0032] The above process can realize the grinding of metal pipe fittings with different diameters and different thicknesses, is convenient for adjustment, saves time and effort, and is conducive to the smooth progress of the grinding process of metal pipe fittings.
