The specific embodiment
As Fig. 1, shown in 2, described adjustable center distance hole processing bull boring device, include driving shaft 17, be characterized in also including: described driving shaft 17 is installed in porous by driving shaft end cap 18 and bores on the shell 6, driving shaft 17 lower ends are provided with driving gear 10, driving gear 10 is meshed with driven gear 11 on the card gear, the lower end of card gear is provided with drill holder 1, drill holder 1 is by first angular contact ball bearing 2, first sleeve 3 and sleeve end cap 4 are arranged on the drilling tool locating template 5, and drilling tool locating template 5 is installed in porous and bores on the shell 6.
Described card gear is four.Described card gear includes driven shaft 12, driven shaft 12 upper ends are installed in porous by second angular contact ball bearing 13, second sleeve 14, round nut 15 and driven shaft end cap 16 and bore on the shell 6, driven gear 11 is installed in driven shaft 12 bottoms, the lower end of driven shaft 12 is provided with cating nipple 24, and cating nipple 24 bottoms link to each other with drill holder 1.Described cating nipple 24 tops comprise ball cage joint shell 9, interior ring 21, retainer 22 and the steel ball 23 that links to each other with driven shaft 12, male splined shaft 8 is arranged in the ball cage joint shell 9 by interior ring 21, retainer 22 and steel ball 23, female splined shaft 7 links to each other with male splined shaft 8, female splined shaft 7 links to each other with the bottom of cating nipple 24, and the substructure of cating nipple 24 is corresponding identical with cating nipple 24 superstructures.Also be provided with inner sleeve 19 on the described driven shaft 12.
Described adjustable center distance hole processing bull boring device, be mainly used in 4 locating holes on the processing automobile usefulness lubricating oil pump pump housing and the pump cover, power drove gear wheel 10 through axle 17 by key when it was implemented, pinion 11 and gear wheel mesh transmission of power to axle 12, universal coupling drives male splined shaft 8, and female splined shaft 7 passes through the cooperation with male splined shaft, makes transmission of power Hooks coupling universal coupling extremely down, by key power is reached drill bit standard fixture 1 then, realize drill tasks.When the centre-to-centre spacing between each pitch-row changes, can realize that the precision between each hole is also controlled by the precision in hole on the template as long as change different drilling tool templates 5.
The operation principle of its cating nipple mainly is: ball cage joint shell 9 is uniform-distribution with six half elliptic annular grooves on the periphery within it, in ring 21 be integral by being threaded with output shaft 8, the interior ring on 21 cylindricals also with equally being uniform-distribution with six half elliptic annular grooves on the shell body, retainer 22 is positioned between shell body 9 and the interior ring 21,21 on shell body 9 and interior ring are all sphere, two spherical bearing faces of shell body 9 and interior ring 21 match, and make the crossed axis angle centering of shell body 9, interior ring 21 and the position of restriction steel ball 23.In six oval annular grooves of shell body 9 and interior ring 21 steel ball is housed respectively, the annular groove of shell body 9 promotes steel ball 23 during transmission, encircles 21 ellipsoid in steel ball promotes again, reaches the purpose of transferring power.When output shaft 8 and vertical guide formation crossed axis angle, because the self-regulated disposition between sphere can make input, output shaft equate at any instantaneous two axis angular rates that all can keep.
When the pitch-row of part to be processed need be readjusted and distance between two Hooks coupling universal coupling joints is changed, because the length of internal spline is greater than the length of external splines, promptly be reserved with certain collapsing length, like this can be under the situation that does not change universal joint structure, the distance between the Hooks coupling universal coupling joint can change.
