[0024] A grinding mechanism 3 is installed at the end of the second rotating arm 2-4, and the grinding mechanism is used to grind the position of the shaft outer circle that needs to be ground; the grinding mechanism 3 includes a grinding machine base 3-1, and a feed frame 3-20 is connected to the grinding machine base through a guide column 3-2. The lower end of the guide column 3-2 passes through the upper crossbeam of the feed frame and is fixed by a locking nut. Adjusting the locking nut can also adjust the expansion and contraction amount of the compression spring; the feed frame is installed with a profiling component 3-3 and a grinding head component 3-4. The profiling component plays a role of profiling limit during grinding to ensure the roundness of the grinding surface;
[0025] A compression spring 3-5 is installed on the guide column between the feed frame and the grinding machine base, and the compression spring makes the grinding head assembly always fit the outer surface of the shaft to be ground. At the same time, the profiling assembly 3-3 and the grinding head assembly 3-4 keep feeding perpendicular to the axial surface under the action of the guide column; an axial feed mechanism 3-6 is also installed on the second rotating arm 2-4, and the axial feed mechanism is used to axially adjust the axial position of the grinding mechanism; the axial feed mechanism includes a third adjustment sleeve 3-60, and the third adjustment sleeve is fixedly connected to the feed frame 3-61, and a screw 3-62 parallel to the second rotating arm is installed on the feed frame, and the screw is connected to the feed motor 3-63; the screw is threadedly connected to the grinding machine base; the axial movement of the grinding mechanism is realized under the drive of the feed motor.
[0026] Preferably, the profiling component 3-3 includes a fourth adjustment sleeve 3-30, the fourth adjustment sleeve is fixedly connected to the profiling fixing sleeve 3-31, a profiling rod 3-32 is inserted in the profiling fixing sleeve and fixed by a fastener, and a profiling wheel 3-33 is installed on the end of the profiling rod through a pin shaft, and the axis of the profiling wheel is parallel to the second rotating arm. During assembly, the depth of the profiling rod inserted into the profiling fixing sleeve is adjusted according to actual needs to meet processing requirements.
[0027] Preferably, the grinding head assembly 3-4 includes a fifth adjustment sleeve 3-40, the fifth adjustment sleeve is fixedly connected to a grinding sleeve 3-41, a grinding rod 3-42 is inserted in the grinding sleeve, and a grinding head 3-43 is installed at the end of the grinding rod.
[0028] Preferably, limit switches 3-7 are installed on the second rotating arms on both sides of the grinding machine base, and the limit switches are connected to the controller of the feed motor to control the operating state of the feed motor.
[0029] When in use, first install the magnetic seat of the magnetic seat motor on the shaft head of the repaired shaft that needs to be repaired, select the unworn shaft surface to perform the centering operation with the dial indicator, and after the center is determined, fix the first rotating arm and the second rotating arm according to the actual situation on site, install the profiling component and the grinding head component on the feed frame, and then the grinding machine seat carrying the profiling component, the grinding head component and the feed frame are integrally mounted on the second rotating arm, and the profiling wheel is adjusted to contact the unworn shaft surface in a tangential form. Then, the second rotating arm with the grinding mechanism 3 installed is completely removed from the second adjustment sleeve, and the second adjustment sleeve fixedly connected to the second rotating arm 2 remains in the existing position, which plays the role of recording the positional relationship between the profiling wheel and the shaft surface.
[0030] Place the disassembled grinding mechanism on the platform with equal height shims to support the second rotating arm, so that the two ends of the second rotating arm, i.e. the profiling wheel, are suspended in the air. Then measure the gap between the profiling wheel and the platform, and select a gauge block equal to the gap to be placed under the grinding head. Fix the position of the grinding head. At this time, the grinding head and the profiling wheel are at the same height. Put the second rotating arm back into the second adjustment sleeve and fix it. The grinding head contacts the surface to be ground on the shaft surface, while the profiling wheel is suspended in the air. When the grinding head removes the excess material, the profiling wheel contacts the shaft surface, indicating that the grinding is finished.
[0031] During the grinding and repairing process, if the grinding surface is too wide to achieve grinding and repairing on the same circumference; start the feed motor while starting the magnetic seat motor, and the magnetic seat motor drives the first rotating arm and the second rotating arm to rotate, the grinding head grinds the surface to be ground, and the feed motor drives the lead screw to rotate, and the lead screw cooperates with the internal threaded hole of the bracket to make the grinding mechanism move axially as a whole. When the grinding mechanism touches the limit switch on one side of the axial direction, the feed motor changes the rotation direction and drives the grinding mechanism to move in the opposite direction. When the limit switch on this side is touched, the feed motor reverses again to achieve reciprocating grinding. In this process, due to the uneven grinding surface, the grinding head will automatically avoid up and down under the action of the spring; as the grinding progresses, the excess part of the outer circle of the shaft is removed, the outer circle grinding of the shaft is completed, and then the entire device is removed.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
