[0012] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 and Figure 2 As shown, the present embodiment involves a grinding assembly for threaded rod processing, including a fixed rod 1 for clamping a turning tool mounting frame, the number of the fixed rods 1 is two and they are arranged symmetrically on the left and right, a first axis 2 and a second axis 3 are connected between the fixed rods 1, the first axis 2 is rotatably connected to two roller frames 4 that are arranged symmetrically on the left and right, a limiting hole 5 is opened on the roller frame 4 and extends circumferentially around the axis of the first axis 2, the second axis 3 is inserted into the limiting hole 5 and moves circumferentially, a grinding roller 6 is rotatably connected between the roller frames 4, a connecting rod 7 is further provided between the roller frames 4, the connecting rod 7 is arranged in a two by two rectangular array between the two roller frames 4, the two roller frames 4 are both threadedly connected to a first locking screw 8 whose end rests against the grinding roller 6, the two fixed rods 1 are both threadedly connected to a second locking screw 9 whose end rests against the roller frame 4, the first locking screw 8 and the second locking screw 9 are both hand-tightening locking screws.

[0016] Furthermore, the circumferential extension angle of the limiting hole 5 is 10° to 30°.

[0017] In this embodiment, the turning tool on the turning tool mounting frame is first removed, and then the grinding assembly disclosed in this technical solution is installed, and the fixing rod 1 is clamped to the turning tool mounting frame to keep the grinding assembly and the turning tool mounting frame fixed. Then the position of the grinding roller 6 is adjusted until the roller surface of the grinding roller 6 is attached to the outer wall of the threaded rod. Finally, the working lathe controls the threaded rod to rotate. During this period, the turning tool mounting frame moves axially, driving the grinding assembly to grind from one end of the threaded rod to the other end, thereby completing the threaded rod grinding operation.

[0018] When the second locking screw 9 is loosened, the roller frame 4 can carry the grinding roller 6 to adjust the elevation position. After the adjustment is completed, the second locking screw 9 can be tightened again.

[0019] Because the grinding roller 6 is in line contact with the workpiece, if the grinding ability of the contact position is lost or weakened due to long-term grinding, the first locking screw 8 can be loosened, the position of the grinding roller 6 can be adjusted circumferentially, and grinding can be performed at another position that forms line contact with the workpiece to ensure the grinding ability of the grinding roller 6. After that, the first locking screw 8 can be tightened again. The grinding roller 6 can be adjusted multiple times, and the grinding service life is long.

[0020] The grinding assembly for threaded rod processing involved in the utility model can complete the grinding operation on the surface of the threaded rod by removing the turning tool on the turning tool holder and clamping the grinding assembly. In combination with a lathe, the grinding assembly can be used without secondary clamping. The grinding is convenient and fast, saving time and labor, and has complete overall functions and strong practicality.
