[0027] The top of the box body 1 is open, and a notch is provided on the top of one side of the box body 1 where the fixing plate 8 is welded. The notch is provided to facilitate the staff to perform grinding work.

[0028] The first shaft 2 and the second shaft 3 both penetrate the box body 1, and the first shaft 2 and the second shaft 3 are distributed on opposite sides of the box body 1, and the axes of the first shaft 2 and the second shaft 3 are on the same straight line. After the guide splint is installed, rotating the second shaft 3 can drive the first shaft 2 to rotate, thereby realizing the flipping of the guide splint, and then grinding different sides of the guide splint.

[0029] The second rotating shaft 3 is provided with two through holes 10 perpendicular to each other, and the pin 9 passes through any one of the two through holes 10 and then passes through the fixed plate 8. After the second rotating shaft 3 and the fixed plate 8 are connected by the pin 9, the second rotating shaft 3 is limited to ensure that the guide splint will not flip during the grinding process.

[0030] A first card slot 11 and a second card slot 12 are respectively disposed on the upper portions of the card block 1 4 and the card block 2 5 .

[0031] The pressure plate 1 6 and the pressure plate 2 7 are respectively located in the card slot 1 11 and the card slot 2 12. One side of the pressure plate 1 6 and the pressure plate 2 7 are respectively abutted against the inner walls of the card block 1 4 and the card block 2 5. The other sides of the pressure plate 1 6 and the pressure plate 2 7 are respectively abutted against the two ends of the guide clamp to prevent the pressure plate 1 6 and the pressure plate 2 7 from moving during the grinding process. The pressure plate 1 6 and the pressure plate 2 7 both have one side with a flat surface and one side with a special-shaped surface.

[0032] The pressure plate 1 6 is bolted to the clamping block 1 4 by means of a bolt pair 13 penetrating the pressure plate 1 6 and the clamping block 1 4 , and the pressure plate 2 7 is bolted to the clamping block 2 5 by means of a bolt pair 13 penetrating the pressure plate 2 7 and the clamping block 2 5 .

[0033] The side of the pressure plate 6 having the special-shaped surface faces the slot 11, and the shape of the space formed by the combination of the special-shaped surface of the pressure plate 6 and the slot 11 matches the shape of one end of the two guide splints. The side of the pressure plate 2 7 having the special-shaped surface faces the slot 2 12, and the space formed by the combination of the special-shaped surface of the pressure plate 2 7 and the slot 2 12 matches the shape of one end of the two guide splints.

[0034] Embodiment 2:

[0035] like Figure 4 As shown, this embodiment provides a grinding tool for a rolling mill guide splint, and its structural structure is basically the same as that of Embodiment 1, except that: one side of the pressure plate 6 having a flat surface faces the slot 11, and the shape of the space formed by the combination of the flat surface of the pressure plate 6 and the slot 11 matches the shape of one end of a guide splint, and one side of the pressure plate 2 7 having a flat surface faces the slot 2 12, and the shape of the space formed by the combination of the flat surface of the pressure plate 2 7 and the slot 2 12 matches the shape of the other end of a guide splint.

[0036] Embodiment 1 can fix two guide splints when in use, and can grind two guide splints simultaneously during grinding. Compared with embodiment 1, this embodiment can fix one guide splint when in use, so as to grind the inside of the guide splint.

[0037] The working principle of the utility model is:

[0038] There are usually two guide splints, and the two guide splints are combined for use. When in use, the two ends of the two guide splints are placed in the card slot 11 and the card slot 2 12 of the card block 1 4 and the card block 2 5, and then the pressure plate 1 6 and the pressure plate 2 7 are respectively placed in the card slot 1 11 and the card slot 2 12, and the profiled surfaces are facing the card slot 1 11 and the card slot 2 12. After bolting, the two ends of the two guide splints are clamped by the card block 1 4, the card block 2 5, the pressure plate 1 6, and the pressure plate 2 7. The upward outer surfaces of the two guide splints are polished, and after polishing, the pin shaft 9 is pulled out, and the rotating shaft 2 3 is rotated 90 degrees. The pin shaft 9 is inserted into the through hole 10 and the fixing plate 8 again, so as to limit the rotation of the rotating shaft 2 3, and the upward outer surfaces of the two guide splints are polished. In this way, the outer surfaces of the two guide splints are polished.

[0039] Alternatively, one guide splint may be polished at a time, and the two ends of one guide splint are placed in the slot 11 and slot 2 12 of the clamping block 1 4 and the clamping block 2 5, and then the pressing plate 1 6 and the pressing plate 2 7 are respectively placed in the slot 1 11 and slot 2 12, and their flat surfaces are facing the slot 1 11 and slot 2 12, and after bolting, the two ends of the two guide splints are clamped by the clamping block 1 4, the clamping block 2 5, the pressing plate 1 6 and the pressing plate 2 7. The upward outer surfaces of the two guide splints are polished, and after polishing, the pin shaft 9 is pulled out, the rotating shaft 2 3 is rotated 90 degrees, and the pin shaft 9 is inserted into the through hole 10 and the fixing plate 8 again, so as to limit the rotation of the rotating shaft 2 3, and the upward outer surface of the guide splint is polished, and the outer surface of the guide splint is polished in this way.

[0040] During the grinding process, the box 1 can block the sparks generated by friction to prevent sparks from flying and causing safety accidents. The two ends of the guide splint are clamped by the clamping block 1 4, the clamping block 2 5, the pressing plate 1 6, and the pressing plate 2 7, so as to prevent the guide splint from tipping over or sliding during the grinding process to avoid injuries to personnel.

Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0042] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
