The machining device is ingenious in concept and reasonable in design, the steering of the left grinding wheel and the steering of the right grinding wheel are set according to the quality of a workpiece, the left grinding wheel and the right grinding wheel rotate in the same direction or in the opposite direction, the machined workpiece is free of cutting marks, and the verticality is good.
Description
Technical Field
The invention relates to the field of bearing machining, in particular to a double-end-face grinding machining method.
Background
When a thin and thick workpiece is ground by using an M7675B grinding machine in the prior art, because the workpiece is relatively heavy, if a left grinding wheel and a right grinding wheel rotate in the same direction for grinding, the workpiece is driven by the grinding wheels to impact on an upper guide plate and a lower guide plate to make a sound, the grain of the grinding surface is not good, and the grinding surface has cut marks;
when a thin-walled workpiece is ground by using an M7675B grinding machine, because the workpiece is relatively light, if left and right grinding wheels are ground by adopting reverse rotation, the workpiece is easily driven by the grinding wheels which rotate reversely, the workpiece runs disorderly in an upper guide plate and a lower guide plate and is easy to incline, the ground workpiece end surface has a larger side and a smaller side on the same side, so that the end surface plane and an outer circular surface incline to form a parallelogram, and the verticality is not good.
The M7675B grinding machine is factory set to rotate in reverse.
Disclosure of Invention
In order to solve the problems, the invention provides a double-end-face grinding method which is ingenious in conception and reasonable in design, the steering of a left grinding wheel and a right grinding wheel is set according to the quality of a workpiece, and the left grinding wheel and the right grinding wheel rotate in the same direction or in the opposite direction, so that the machined workpiece has no cutting mark and is good in verticality.
The technical scheme of the invention is as follows:
a double-end-face grinding method is characterized in that a double-end-face grinding machine is used for grinding two end faces of a workpiece at the same time, the double-end-face grinding machine comprises an upper guide plate and a lower guide plate which are arranged in an up-and-down symmetrical mode, and a left grinding wheel and a right grinding wheel which are arranged oppositely.
When the weight of the workpiece is large, the left grinding wheel and the right grinding wheel rotate reversely: before a workpiece enters the grinding wheel, the workpiece moves forward along the lower guide plate, and when the workpiece just enters the grinding wheel, the workpiece is relatively heavy, so that the workpiece is difficult to be driven by the grinding wheel rotating reversely when the left grinding wheel and the right grinding wheel rotate reversely and grind, the workpiece cannot jump in the upper guide plate and the lower guide plate, the workpiece is supported by the lower guide plate, the size of the same surface of the end face of the ground workpiece is equivalent, the end face plane and the outer circular face cannot be inclined, the rectangular shape is formed, and the verticality is.
When the weight of the workpiece is small, the left grinding wheel and the right grinding wheel rotate in the same direction: before a workpiece enters the grinding wheel, the workpiece moves forward along the lower guide plate, is brought to the upper side by the grinding wheel rotating in the same direction when entering the grinding wheel, moves forward along the upper guide plate, is brought to the lower side by the grinding wheel rotating in the same direction when passing through a half part of the grinding wheel, moves forward along the lower guide plate, and is discharged along the lower guide plate after being ground. Therefore, the workpiece can be vertically positioned in the grinding process, and the phenomenon of random movement cannot occur, so that the phenomenon that the end face of the workpiece is large and small at the same time, namely the verticality is poor, is avoided.
The technical scheme is further improved and refined, and the double-ended grinding machine is an M7675B double-ended grinding machine.
The technical scheme is further improved and refined, the left grinding wheel and the right grinding wheel are respectively inclined at an angle in the horizontal plane, the distance between the inlet side and the outlet side of the left grinding wheel and the right grinding wheel is smaller than that between the inlet side and the outlet side, the allowance of the end face of the workpiece is uniformly ground, and the purpose of improving the grinding precision is achieved.
The invention has the advantages that the design is ingenious, the design is reasonable, the steering of the left grinding wheel and the right grinding wheel is set according to the quality of the workpiece, and the left grinding wheel and the right grinding wheel rotate in the same direction or in the opposite direction, so that the processed workpiece has no cutting mark and good verticality.
