Technical Field
The invention relates to the technical field of grinding equipment, in particular to a grinding machine for machining a rotor groove of a vane motor.
Background
When grinding the rotor groove, the stability of the single-point support rotor groove is poor because the vibration amount generated by the reciprocating motion during grinding is large, so that a support tool with a plurality of clamping points is usually required to be set on a workbench for grinding the rotor groove. However, as the number of the rotor grooves of the blades is large, the contact area between the clamping points of the support and the outer wall of the rotor is lost when the positions of the grooves of the rotor grooves are close to the covering surfaces of the clamping points. In order to compensate the loss of the contact area of the part, the support can drive the clamping points close to the notch position of the rotor groove to move continuously along the outer wall of the rotor until the contact surfaces of the clamping points are separated from the notch position of the rotor groove and are covered on the solid surface of the inner cavity of the rotor, at the moment, if the clamping points close to the notch position of the rotor groove are more, after the actual covering surfaces of the clamping points are all driven by the workbench to change in movement, the grinding measurement coordinates conforming to the covering surfaces of the original set clamping points are slightly misplaced, so that the movement track during grinding is accumulated due to the misplacement of the grinding measurement coordinates, and the movement track exceeds the allowable error range. As the dynamic advancing track of grinding is gradually moved to the inner groove by the outer groove, once the grinding end and the right angle surface of the edge part of the rotor are changed to generate contact pressure due to the change of the moving track during grinding, the right angle surface of the edge part of the rotor can directly lose the original angle, namely the requirement of blade assembly can not be met, and the damage degree is higher.

The numerical control executing end 1 is used for setting a moving direction command of the bidirectional transmission workbench 2 during grinding operation, the inner supporting and positioning clamp 5 is an existing multi-clamping-point support, and after the inner supporting and positioning clamp 5 stretches into the inner side of a central groove of a rotor, the clamping end of the inner supporting and positioning clamp is expanded along the inner side of the central groove, so that multi-point support of the rotor is realized. In this embodiment, during the grinding process, the numerical control executing end 1 sets the bidirectional transmission workbench 2 to a front-rear grinding mode, and the bidirectional transmission workbench 2 drives the workbench 4 to reciprocate back and forth, so that the embedded grinding part 621 realizes grinding along the inner side of the rotor groove fixed by the workbench 4.
The invention provides the problems in the prior art that the contact area between the clamping point of the support and the outer wall of the rotor is lost when the notch position of the rotor groove is close to the cover surface of the clamping point due to the large number of the rotor grooves of the blades.
