Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of grinding clamp device of the utility model, comprising: tongue tail cone cover 1, self-centering pawl dish 2, universal upper junction plate 3, universal lower connecting plate 4, axle sleeve 5, nut 6, grinding rod 7, short connecting rod 8, screw 9, johning knot 10, three-jaw chuck 11, hold-down screw 12, connecting rod 13 and hold-down nut 14; Described three-jaw chuck 11 is loaded on self-centering pawl dish 2, self-centering pawl dish 2 is fixed on tongue tail cone cover 1 by hold-down screw 12, universal upper junction plate 3 and universal lower connecting plate 4 johning knot 10 connect to form universal johning knot, and connecting rod 13 is locked through universal lower connecting plate 4 one end hold-down nut 14; Three-jaw chuck 11 connects universal upper junction plate 3, and universal lower connecting plate 4 is by screw 9 connecting bushing 5, and grinding rod 7 packs in axle sleeve 5, and fix with short connecting rod 8, short connecting rod 8 one end nut 6 is locked.
As shown in Figure 3, the course of work of the utility model device is as follows:
(1) main shaft housing 15 to be ground is flat on radial drill working plate 16, measures the size in the upper and lower aperture of main shaft housing with inside micrometer, and record;
(2) grinding rod is made according to the maximum of main shaft housing by the gross; Grinding rod is solid grinding rod, and material selection wear resistant cast iron, has to pass through Precision Machining, ensures the linearity of grinding rod, precision, tapering and circularity; Grinding rod divides second gear: 1: rough lapping rod, is threaded line (impurity can taken away abrasive pastes and grind), mainly removes surface spikes, and utilize rough lapping cream to carry out small cutting, improves circularity, tapering; 2: lappingout frotton, optical wand, main raising bore area fineness, plays polishing effect.Example: the maximum upper deviation of main shaft housing aperture size maximum in main shaft housing is by the gross+0.010mm---+0.005mm, the grinding rod then originally made is of a size of maximum housing aperture, try vertically to put into main shaft shell inner hole, if about grinding rod being put into half, this root grinding rod can employ, if half root length very tightly can not be put into when putting into, then again grinding rod is ground off 0.5 μm a little, try again vertically to put into, until the grinding rod of half root length can be put into main shaft housing aperture;
(3) main shaft housing 15 to be ground is fixed on radial drill working plate 16, time fixing, housing is by the padded 40-100mm of cushion block 17, when preventing from grinding, grinding rod touching bumps against radial drill working plate 16, affect Grinding Quality, the tongue tail cone of grinding clamp device of the present invention cover 1 is put in radial drilling machine;
(4) open radial drill, rotating speed controls at 25 revs/min, coordinating, suitably on grinding rod, smearing kerosene or abrasive pastes when grinding according to the degree of tightness of grinding rod with main shaft housing, and rotating speed must control in rotating, and grinding can be made to contact more comprehensively;
(5) grind certain hour and take out grinding rod, the aperture size up and down of main shaft housing is measured again with inside micrometer, if the error in aperture is within the scope of 0.002mm up and down, grind successfully, otherwise, little one end, main shaft housing aperture must be ground again, grounds travel can be coated with continue grinding on grinding rod, if upper hole is less than normal, grinding rod is stretched down a bit of, if lower opening is less than normal, hydrostatic spindle housing must be inverted and be fixed on working plate and continue grinding, until namely complete grinding by the deviation that inside micrometer is measured within the scope of 0.002mm; After the aperture of hydrostatic spindle housing is ground, assemble hydrostatic bearing, same method can grind the bore area of hydrostatic bearing.
Grind from maximum size in hydrostatic spindle housing by the gross, grinding can make grinding rod loss to some extent, then descending order grinding just, if the size of grinding rod can not meet grinding when requiring, then need to make a satisfactory grinding rod according to the size of remaining hydrostatic spindle shell inner hole again, undersized grinding rod can be modified as from used grinding rod, reach cost-savingization and produce, the endoporus grinding housing is continued, until will grind by hydrostatic spindle housing by the gross with this.
