[0009] It can be seen that in the above technical solution, the output end of the electric push rod extends to drive the slide plate to adjust the position on the extension plate, thereby enabling the axle pin seat and the first support wheel to be displaced, and the grinding belt is tensioned and adjusted. When the grinding belt is tensioned and adjusted, the second support wheel is subjected to the traction force caused by the deformation of the grinding belt to adjust the angle at the end of the extension plate, so that the deflection plate can continuously press against the inner wall of the grinding belt, which makes it easy for the second servo motor to drive the traction wheel to rotate and drive the grinding belt to rotate to grind the crankshaft journal. When the grinding belt rotates, it is displaced through the axle pin seat and the first support wheel, so that the grinding belt is U-shaped and wrapped around the outside of the crankshaft, thereby realizing the function of comprehensive grinding of the crankshaft and ensuring the grinding efficiency and effect.

[0011] It can be seen that in the above technical scheme, the crankshaft is limited by the clamping jaws and the limiting cylinder, and at the same time, the third slide is driven by the hydraulic rod to drive the limiting cylinder to slide on the lining seat, so as to realize the function of position adjustment of the third slide and the limiting cylinder, so that one end of the crankshaft can be inserted into the limiting cylinder to ensure the stability of the crankshaft during grinding. At the same time, during grinding, the first slide is driven by the first screw transmission module to adjust the position on the lining seat, so as to realize the function of adjusting the position of the grinding wheel and the grinding teeth, so as to facilitate the grinding of different areas of the crankshaft. At the same time, the second slide is driven by the second screw transmission module to drive the first servo motor, the grinding wheel and the grinding teeth to move on the first slide, so that the grinding wheel and the grinding teeth can be close to the crankshaft, and then the first servo motor drives the grinding wheel and the grinding teeth to rotate to grind the crankshaft journal.

[0012] The present invention has the following advantages:

[0013] 1.

[0014] 2. When the first slide seat of the present invention is adjusted in position on the liner seat, it can also drive the various structures on the extension plate and the slide plate to adjust their positions synchronously, so that the second servo motor drives the traction wheel to rotate and drives the grinding belt to rotate to grind the crankshaft journal, thereby realizing the function of synchronous grinding of the grinding teeth and the grinding belt, and realizing the diversity of grinding;

[0015] 3. The present invention extends the output end of the electric push rod to drive the slide plate to adjust the position on the extension plate, thereby allowing the shaft pin seat and the first support wheel to be displaced, and the grinding belt is tensioned and adjusted. When the grinding belt is tensioned and adjusted, the second support wheel is subjected to the traction force of the grinding belt deformation to adjust the angle at the end of the extension plate, so that the deflection plate can continuously press against the inner wall of the grinding belt. Through the displacement of the shaft pin seat and the first support wheel, the grinding belt is conveniently wrapped in a U shape on the outside of the crankshaft, so as to realize the function of comprehensive grinding of the crankshaft and ensure the grinding efficiency and effect;
