(5) specific embodiment
The present invention will finish the boring processing of each bearing propeller boss endoporus of marine shafting, axis coaxle degree in order to ensure each bearing propeller boss, must make boring bar have good linearity, because the diameter of boring bar and length ratio are 1 usually: 25-1: between 40, belong to the elongate rod structure, be difficult in the linearity that guarantees the boring bar axis under the situation of two strong points, therefore will in the middle of boring bar, add the strong point.Special-purpose intermediate supports can not opened under the condition of fabrication hole at the stern tube shaft pipe, and operating personnel can externally adjust, and reaches to eliminate the boring bar amount of deflection, makes the purpose of boring bar axis and hull dead in line.
Marine stern axle tube boring technological equipment erecting process, its processing step is as follows:
1, intermediate support position definite opinion Fig. 3 really in the stern tube shaft pipe.According to stern tube shaft pipe 10 set external reinforcing rib 13 positions when hull sets up, the intermediate supports 12,14 of boring bar 1 is located near head and the tail bearing inner side end and outside breadthrider 13 corresponding positions in the stern tube shaft pipe 10, determines the distance L of two intermediate supports 12,14
1, stern datum mark 9 and back intermediate supports 12 distance L
2, bow datum mark 16 and preceding intermediate supports 14 distance L
3And the boring bar outer end is to the distance L of stern datum mark 9
4, and record.
2, the linearity of measuring boring bar is seen Fig. 1, the boring bar of selecting 1 is installed on its linearity of measurement on the lathe, boring bar 1 one ends and chuck 3 chuckings, the other end withstands on top 2, measuring method routinely, the jerk value in four orientation on 1.5m measurement boring bar 1 circumference is respectively at I, II, III ... the point reading performs record, and the linearity that should select boring bar is in 0.10mm.
3, the deflection value of analogue measurement boring bar cantilever is seen Fig. 2.The 1 position (see figure 3) of intermediate supports 12,14 in stern tube shaft pipe 10 of determining simulated the axial location size of intermediate supports 12,14 and established two supports 5 set by step, and making two supports, 5 spacings is L
1, boring bar 1 level frame being located at two supporting on 5, the axial location of boring bar 1 one ends and support 5 is by L
2+ L
4Determine, be noted that especially the keyway 7 on the boring bar will face down, set up a bridge gauge 4 again in the boring bar side of setting up, bridge gauge 4 upper surfaces are adjusted level, measure 1 liang of fulcrum of boring bar, 5 intermediate supports positions, make the axis at boring bar 1 intermediate supports position parallel, measure boring bar 1 two ends cantilever (bow, stern datum mark position) L respectively with dial gauge 6 then with bridge gauge 4
2And L
3Deflection value, its reading performs record and mark in order to adjusting.
4, the boring process frock is set up and is seen Fig. 3.In order to ensure the axiality after the processing of each bearing, propeller boss hole, must adjust centering boring bar axis and hull dead in line, consistent when the direction of boring bar keyway 7 should be with analogue measurement cantilever deflection value during adjustment, setting up in line with mentioned above principle of its technology and pattern assembly divides again:
(1) presses the position of stern tube shaft pipe two ends stern, bow datum mark 9,16 centering boring bars 1, with 12,14 of two intermediate supports in being welded on the stern tube shaft pipe in advance on the ring pad 14 of (non-working position), unclamp and withdraw from supporting bearing adapter sleeve 17 (see figure 4)s on 8 outside boring bar 1 two ends, make boring bar 1 two ends be cantilever position.
(2) adjust intermediate supports 12 (see figure 6)s, adjust intermediate supports 12, make boring bar 1 relative stern datum mark 9, make l by adjusting lever 11
4With l
3Equate, and press boring bar 1 suspended wall deflection value adjustment, cantilever deflection is l
1-l
2, adjustment amount should equal 2 times of cantilever deflection value.Adjust intermediate supports 14 with bow datum mark 16 equally.Above-mentioned intermediate supports 12,14 is formed (see figure 5) by worm gear 19, worm screw 20, jackscrew 21 respectively, drive worm screw 20 rotations that are connected with adjusting lever 11 by rotating adjusting lever 11, worm screw 20 drives worm gear 19 and rotates, worm gear 19 drives connected jackscrew 21 and moves axially, jackscrew 21 promotes intermediate supports 12 motions, thereby regulates the radial position of boring bar 1.
(3) set up support 8 outside boring bar 1 two ends, it is welded on respectively on hull board and the bulkhead 15, after treating boring bar 1 intermediate supports 12,14 adjustment finishing in stern tube shaft pipe 10, the outer bearing adapter sleeve 17 that supports on 8 of multiple dress, and with fastening screw 18 locking (see figure 4)s, adjust outer 8 the radial position of supporting again, make adjust boring bar 1 with stern tube shaft pipe 10 two ends datum marks 9, about in the of 16, about apart from equating, i.e. l
1=l
2, l
3=l
4, lift the cantilever deflection value of boring bar 1.
Above-mentioned boring bar is adjusted centering and is finished, and the boring bar axis overlaps with the hull theoretical axis, and its described processing step is a marine stern axle tube boring technological equipment erecting process.
