Description
Technical field
The present invention relates to a kind of lathe equipments, particularly a kind of internal surface of column turning equipment.
Background technology
Parts cylindrical form interior surface turning processing is when the axis direction size of parts is big, be difficult to carry out cylindrical form interior surface turning processing or can not turning processing, here said can not turning processing column shape inner surface, the nulling part inside diameter is the turning processing of Φ 220～Φ 800mm and axis direction size 8000～10000mm cylindrical form interior surface.For iron and steel parts, the following boring of Φ 200mm, the axis direction size is generally in 3000mm.Bore if allow to turn around, also be difficult to guarantee the axiality of cylindrical form interior surface that twice boring forms.And some parts only requires side processing.Use the boring machine machining hole, the diameter range in hole is much larger than drilling machine, but the length restriction of boring bar the depth dimensions of machining hole (being the axis direction size).Use the machined into hole, as adopting vertical lathe processing column shape inner surface, also have and the boring machine similar problem, also have the cutter lever arm longer, machining accuracy is subjected to the influence of amount of deflection.
Need carry out the turning processing of cylindrical form interior surface, be the new problem that makes constant progress and occur along with domestic manufacturing technology.For example, papermaking equipment has a large amount of each rollers, because of improving constantly of the speed of a motor vehicle, and the continuous increase of face width size (existing) above 8 meters long rollers, also more and more higher to the processing request of roller.Paper machine speed is below 500m/min, and internal diameter is that the roller cylindrical form interior surface of Φ 220～Φ 800mm does not require processing.After paper machine speed surpassed 500m/min, paper machine vibration noise obviously aggravated.Through repetition test, learn that causing the reason of paper machine vibration aggravation is that each rollers inner surface is undressed, causes roller wall unevenness everywhere.The steel pipe that straight welded seam is particularly arranged, its inner surface commissure often have the rough and uneven in surface and distortion of weld metal, cause motion imbalance in the rotation of roller dead axle.Under higher speed of a motor vehicle condition, the centrifugal action aggravation, the impulsive force increasing to supporting structure strengthens paper machine vibration noise.This vibration produces harmful effect to the papermaking quality.
However, domestic before manufacturing industry can't be finished the turning processing of Φ 220～Φ 800mm and axis direction size 8000～10000mm cylindrical form interior surface always.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of turning equipment for cylindrical internal surface, this equipment can be finished the turning processing of Φ 220～Φ 800mm and axis direction size 8000～10000mm cylindrical form interior surface, processing back inner surface is smooth, smooth, the workpiece wall thickness is even, workpiece dynamic balance accuracy height can effectively reduce the vibration of paper machine.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of turning equipment for cylindrical internal surface comprises the head of a bed, lathe bed, chuck, center bearing bracket, hold-down support, sliding support and cutter driven rod, the head of a bed and lathe bed fixed-site, and the head of a bed is in an end of lathe bed;
The head of a bed is provided with gear-box, the clutch end of gear-box chuck one side elevation that is connected, this lathe bed deviate from the head of a bed above be aligned in sequence with center bearing bracket, hold-down support and sliding support, center bearing bracket is fixed in above the lathe bed, workpiece one end spline is loaded on chuck opposite side facade, rotate by chuck and to drive workpiece and rotate, the inner ring (promptly described relatively inner ring can relatively rotate) of center bearing bracket is passed in the activity of the workpiece other end, the center of rotation of chuck, the axle center of workpiece keeps concentric with the inner ring axle center of center bearing bracket, guarantee machining accuracy with this, guarantee workpiece wall thickness unanimity, be installed with slide rail in the lathe bed, the sliding support linear slide is on slide rail, the glide direction of sliding support and the central axes of workpiece, cutter driven rod one end (the right among the figure) is fixed on the sliding support, hold-down support is fixedly arranged on the lathe bed, the activity of the cutter driven rod other end wore hold-down support (being that both can relatively move), this cutter driven rod other end is provided with the cutter processing unit (plant), cutter is fixed on that (the cutter processing unit (plant) can be realized advance and retreat radially on the cutter processing unit (plant), this example of prior art no longer illustrates), the cutter processing unit (plant) is in the side of hold-down support near center bearing bracket;
Be provided with a leading screw again in the lathe bed, the power intake of leading screw connects rotary power output (can by gear drive or directly transmission), driving leading screw with this rotates, kinematic pair by screw-threaded engagement on leading screw, realize that straight line moves back and forth, the sliding support kinematic pair that is connected moves with this straight line back and forth of realizing sliding support.
Also be provided with a cooling fluid mechanism, cooling fluid mechanism comprises liquid storage tank and feed pipe (pumping installations is arranged), store cooling fluid in the liquid storage tank, the feed pipe two-port communicates respectively in liquid storage tank and cutter processing unit (plant), cooling fluid in the liquid storage tank is trickled to the machined surface of cutter contact, thereby add the cooling in man-hour fully.
Evenly be interval with at least three rollers on the inner ring of center bearing bracket, workpiece places between the rolling surface of roller, realizes rotating relative to described inner ring with this.
Described center bearing bracket and hold-down support slidably are fixedly arranged on above the lathe bed, so that according to their position of size adjusting of work piece.
The invention has the beneficial effects as follows: the invention solves Φ 220mm～Φ 800mm and axis direction length 8000mm～10000mm roller cylindrical form interior surface turning processing problems, maximum and minimum diameter difference is not more than 0.5mm, and the roller kinematic accuracy is greatly improved; The all even inner surface of wall thickness is smooth everywhere to use work piece after this example processing, dynamic balance accuracy effectively improves, thereby has reduced the vibration of paper machine, has reduced noise, the quality of the paper that obtains simultaneously is improved equally, has reduced the maintenance cost of paper machine.
