In this embodiment, a conveying motor for driving the conveying roller 11 to rotate is also installed on the conveying frame 1 .

[0022] The working principle of the utility model is as follows: when in use, the frog to be processed is placed on the conveying roller 11, and is transported to the left by the conveying roller 11. Then, the frog is blocked by the positioning mechanism 2, and the conveying roller 11 stops conveying. Subsequently, the frog is fixed by the fixing mechanism 3. Next, the grinding motor 62 is started, and the grinding motor 62 drives the grinding rod 63 to rotate. Then, the position of the grinding rod 63 is adjusted by the moving mechanism 4 in cooperation with the adjusting mechanism 5, so that the grinding rod 63 extends into the groove of the frog, thereby grinding the inside of the groove. At the same time, the grinding sheet 64 can grind the upper part of the frog, thereby improving the grinding effect and better meeting the use requirements.

[0023] As a further solution, the positioning mechanism 2 includes a positioning frame 21 installed at the lower end of the conveying platform 1, and a positioning electric push rod 22 is installed at the lower end of the positioning frame 21. The telescopic end of the positioning electric push rod 22 passes through the positioning frame 21 and is fixed with a positioning seat 23. A positioning baffle 24 is also installed at the upper end of the positioning seat 23.

[0024] The working principle of the positioning mechanism 2 is: during positioning, the positioning electric push rod 22 extends to push the positioning seat 23 upward, so that the positioning baffle 24 extends above the conveying platform 1 to block the frog, making it easier for the fixing mechanism 4 to fix.

[0025] As a further solution, the fixing mechanism 3 includes a pair of fixing seats 31 installed on the upper end of the conveying platform 1, and each of the fixing seats 31 is installed with a fixed electric push rod 32, and the telescopic end of the fixed electric push rod 32 passes through the fixing seat 31 and is installed with a fixed clamping plate 33, and fixed limit blocks 34 are also installed at both sides of the fixed clamping plate 33, and chamfers 35 are also provided on the opposite sides of the fixed limit blocks 34. By providing the chamfers 35, it is convenient for the frog to be inserted between the fixed limit blocks 34.

[0026] The working principle of the fixing mechanism 3 is as follows: when fixing, the fixed electric push rods 32 on both sides extend to push the fixed clamping plates 33 closer to each other, so that the frog is fixed. At this time, the fixed limit blocks 34 on the left and right sides of the fixed clamping plates 33 can limit the left and right sides of the frog, thereby improving the fixing effect and facilitating subsequent grinding work.

By driving the adjustment motor 54 to drive the adjustment screw 55 to rotate, the movement of the adjustment slide 56 can be achieved. By adjusting the forward and reverse rotation of the adjustment motor 54, the forward and backward movement of the adjustment slide 56 can be achieved, which is convenient for grinding different positions of the frog.
