Abstract
The utility model relates to an eccentric long conical hole boring device. A large mop transmission screw rod is mounted at the upper part of a base of a boring machine; a large mop is mounted on the large mop transmission screw rod; a pair of adjustable V-shaped iron blocks is fixedly mounted at the front and back parts of the upper part of the large mop; positions for mounting workpieces are arranged at the upper ends of the adjustable V-shaped iron blocks. According to the utility model, the center line of an eccentric inner hole of a workpiece is adjusted to a horizontal position by utilizing the pair of height adjustable iron blocks; the eccentric long conical hole boring device in use is reasonable in structure, convenient and flexible to use, excellent in the processing effect and high in the production efficiency.
Description
Technical field
The utility model belongs to machining equipment technical field, relates to the device of the eccentric oval taper hole of a kind of boring that cone machine eccentric bushing is processed.
Background technology
Eccentric bushing, as cone machine major part, is difficult point in process all the time, all adopts in the past big vertical lathe, adopts frock, and workpiece pad is oblique, then swivelling tool-holder processing work, takies resource large, and frock efficiency is low.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides the device of a kind of rational in infrastructure, easy to use and flexible, processing effect is good and production efficiency the is high eccentric oval taper hole of boring.
The utility model solves the technical scheme that its technical problem adopts: the device of the eccentric oval taper hole of a kind of boring, large mop drive lead screw is being housed above the base of boring machine, on large mop drive lead screw, large mop is being housed, before and after above large mop, be respectively installed with a pair of adjustable v-type iron, in the upper end of adjustable v-type iron, be provided with the position that workpiece is installed.
Boring machine is equipped with main shaft, and main shaft is connected with boring bar power with terminal pad two by terminal pad one, and servomotor is connected with the screw mandrel power on boring bar with support ring by power transmission shaft, gear one, gear two, universal coupling, and the screw mandrel of rotation is connected with knife rest power.
The output shaft of servomotor is connected by shaft coupling and power transmission shaft.
Screw mandrel is arranged on boring bar by taper roll bearing and bearing block.
The knife rest screw and nut that cutter is housed is arranged on screw mandrel.
The beneficial effects of the utility model are: utilize a pair of adjustment height v block, the center line of endoporus extremely eccentric workpiece correction, to horizontal level, is loaded onto to this frock.Machine tool chief axis links together with screw with boring bar by terminal pad one and terminal pad two, realize main shaft and drive boring bar rotation, realize the hoop cutting movement of cutter, servomotor passes through power transmission shaft, a pair of gear, universal coupling drives the screw mandrel rotation of support ring on boring bar, and the screw mandrel band movable knife rack of rotation is done feed motion; Because the setting angle of screw mandrel tilts with respect to machine axes, intersect with machine axes, the angle of cut of itself and machine axes equals the cone angle of workpiece to be machined, therefore to rotarily drive the motion of knife rest be both direction to screw mandrel, be also to do radial motion outside the motion of edge machine axes, realize conical bore processing, its rational in infrastructure, easy to use and flexible, processing effect is good and production efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A cross-sectional view in Fig. 1.
In figure: 1-boring machine, 2-adjustable v-type iron, 3-screw mandrel, 4-bearing block one, 5-bearing block two, 6-taper roll bearing, 7-knife rest, 8-cutter, 9-universal coupling, 10-gear one, 11-gear two, 12-power transmission shaft, 13-servomotor, 14-terminal pad one, 15-terminal pad two, 16-boring bar, 17-workpiece, the large mop drive lead screw of 18-, the large mop of 19-, 20-shaft coupling, 21-bearing block, 22-workpiece female cone axially bored line, 23-excircle of workpiece axis.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Referring to Fig. 1 and Fig. 2, the device of the eccentric oval taper hole of a kind of boring, large mop drive lead screw 18 is being housed above the base of boring machine 1, on large mop drive lead screw 18, large mop 19 is being housed, before and after above large mop 19, be respectively installed with a pair of adjustable v-type iron 2, the upper end of adjustable v-type iron 2 is provided with the position that workpiece 17 is installed.
The main shaft of boring machine 1 is connected with boring bar 16 power with terminal pad 2 15 by terminal pad 1, servomotor 13 is connected with screw mandrel 3 power on boring bar 16 with support ring by power transmission shaft 12, gear 1, gear 2 11, universal coupling 9, and the screw mandrel 3 of rotation is connected with knife rest 7 power.
The output shaft of servomotor 13 is connected by shaft coupling 20 and power transmission shaft 12; Screw mandrel 3 is arranged on boring bar 16 by taper roll bearing 6 and bearing block 21; The knife rest 7 use screw and nuts that cutter 8 is housed are arranged on screw mandrel 3.
The utility model utilizes a pair of adjustment height v block, and the center line of endoporus extremely eccentric workpiece correction, to horizontal level, is loaded onto to the utility model.Machine tool chief axis links together with screw with boring bar by terminal pad one and terminal pad two, realize main shaft and drive boring bar rotation, realize the hoop cutting movement of cutter, servomotor passes through power transmission shaft, a pair of gear, universal coupling drives the screw mandrel rotation of support ring on boring bar, and the screw mandrel band movable knife rack of rotation is done feed motion; Because the setting angle of screw mandrel tilts with respect to machine axes, intersect with machine axes, the angle of cut of itself and machine axes equals the cone angle of workpiece to be machined, and therefore to rotarily drive the motion of knife rest be both direction to screw mandrel, being that the motion of edge machine axes is outer also does radial motion, realizes conical bore processing.
