Embodiment
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiments of the invention, but the present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar change thereof, all should list protection scope of the present invention in.
As Figure 1-Figure 4, a kind of rotor grinding attachment that the embodiment of the present invention provides, comprise two grinding machines 11,12, two grinding machines are between left and right every laying, the power output shaft of left grinding machine 11 is wherein fixed with a clamping dish 31, right grinding machine 12 has a tailstock top 35 that can move left and right, and be equipped with for driving tailstock to come directly towards the 35 top driver parts moved left and right on right grinding machine 12;
Described clamping dish 31 is equipped with one to move left and right and can with the driver plate 33 of clamping dish synchronous axial system, clamping dish 31 is fixed with the many driver plate guide pillars 39 moved left and right for guiding driver plate, every root driver plate guide pillar 39 is all equipped with driver plate spring 34, and the two ends of each driver plate spring 34 prop up clamping dish 31 and driver plate 33 respectively;
The middle part of described driver plate 33 has one for the outstanding boss 38 of clamping workpiece to the right, the core of driver plate 33 offers through hole, this through hole is built-in with a fixing top 32 coordinated with driver plate activity, this fixing top 32 is affixed with clamping dish 31, and the central axis of fixing top 32 and tailstock come directly towards the central axes of 35.
In the embodiment of the present invention, a workbench 4 is fixed with between described two grinding machines 11,12, described workbench 4 is fixed with each work support 5 around, these two work support 5 intervals are laid, the top of two work supports 5 all offers the upwards open and V-arrangement work-piece groove 51 that left and right is through, and the central axis of fixing top 32 is through the work-piece groove on two work support 5 tops.
The embodiment of the present invention also comprises two charging trays 21,22, and these two charging trays are placed in both sides before and after workbench, and one of them charging tray 21 is entry table, and another charging tray 22 is discharge port plate.
The measuring instrument for measuring workpieces grinding spot size described grinding machine is equipped with in the embodiment of the present invention.
The embodiment of the present invention is applicable to the bearing position of rotor and the grinding of oil sealing position, and concrete processing method is as follows:
As shown in Figure 5, the rear end of processing work to be ground (rotor) needs the fan blade keyway 97 for installing fan blade that milling is in advance good, and workpiece needs the position of grinding to have fore bearing position 93, Front oil seal position 92, rear bearing position 95, Rear oil seal position 96;
Each needs the workpiece of grinding (rotor) will be placed in advance on entry table, add utilization of hour mechanical gripper grabbing workpiece be placed on two work supports one by one from entry table, after often processing a workpiece, the workpiece utilizing mechanical gripper to capture to be placed on two work supports also relays on discharge port plate;
