Description
Technical field
The present invention relates to a kind of longaxones parts processing of lathe, the especially processing of pipe part, when workpiece overhangs longer through spindle through-hole, the effect of aiding support workpiece can be played, improve stability and the reliability of machine tooling longaxones parts.
Background technology
Current most of longaxones parts lathe add man-hour, the structure of assistant support form used is that a set of centre frame lower body is housed on base, its operation principle is the same with centre frame, ensures the center of workpiece by adjusting two back shafts, meets instructions for use.Because this auxiliary support apparatus is rigidity, the impact and " other strength " phenomenon that produce with carrying roller because of pipe themselves bend when tube to tubesheet rotates can not be overcome, thus cause the vibrations of the parts such as auxiliary support apparatus, Lathe Spindle Box, lathe bed.Produce the defect such as ripple and poor surface smoothness when machining screw, product quality requirement can not be reached.Meanwhile, body has also been rolled the flute mark of dark about 0.5mm by roller, not only destroys the polishing of workpiece outer wall, and will cause and forge a knife, and damages the serious problems such as main auxiliary machine plant equipment.In addition, originally auxiliary support apparatus is fixed on lathe ground, can not move axially along processing parts, can not meet the workpiece of different length.Production efficiency is low, and labour intensity is large, and finished product percent defective is high, thus causes production cost very high.
Summary of the invention
The object of the invention is to, for avoiding the deficiencies in the prior art, providing a kind of lathe auxiliary support apparatus.To solve the auxiliary support apparatus of conventional rigidity, the impact and " other strength " phenomenon that produce with carrying roller because of pipe themselves bend when tube to tubesheet rotates can not be overcome, and cause the vibrations of the parts such as auxiliary support apparatus, Lathe Spindle Box, lathe bed.Produce the defect such as ripple and poor surface smoothness when machining screw, product quality requirement can not be reached.。
For achieving the above object, the technical scheme that the present invention takes is: a kind of lathe auxiliary support apparatus, its main feature is, symmetrically arranged backing roll is located at the top of support, below and the lifting screw of support are fixedly hinged, also be provided with screw case in the below of support, worm and wheel engages, and lifting screw is the central shaft of worm gear; Be arranged with guide post in the below of support, guide post is provided with spring, and support and guide post are movably hinged; Butterfly spring is provided with above screw case.
Described lathe auxiliary support apparatus, also include reducing motor output shaft and connect active synchronization belt wheel, drive driven synchronous pulley by Timing Belt, driven synchronous pulley is located at the two ends of guide rail, makes it axially move.
Described lathe auxiliary support apparatus, characterized by further comprising and be provided with locking pressure plate on guide rail.
Described lathe auxiliary support apparatus, is characterized in that the outer loop material of described backing roll is wear resistant nylon.
The present invention be directed to original auxiliary support apparatus in use Problems existing, by the Long-term analysis research of the longaxones parts processing technology to lathe, through force analysis, theory calculate, after repetition test and long term production prove, the new device designed, structure of the present invention is overcoming rigid support and irremovable shortcoming and designing vertically, the present invention is by backing roll, bearing, fixed hinge, butterfly spring, worm gear, worm screw, active synchronization belt wheel, Timing Belt, driven synchronous pulley, directive wheel, locking pressure plate, lifting screw, worm screw case, guide post, the compositions such as spring.This device by a pair backing roll, can asking workpiece to rotate, being provided with butterfly spring vibration absorber and oscilaltion mechanism, for supporting the handling of different-diameter workpiece and workpiece below roller.Aiding support is located on guide rail, drives this device to axially move on guide rail by reducing motor, for supporting the workpiece of different length easily, meanwhile, realizes self-feeding by moving axially on guide rail.Swing the quadric chain formed by parts such as worm screw case, guide post, supports, and oscilaltion is by Worm Wheel System.In tube to tubesheet process, the movement locus of roller center point remains a circle under the effect of workpiece, thus plays floating action.Both sides guide post hangs with two groups of springs be elevated at support and swing in order to buffering, and make backing roll be in center when zero load.
Beneficial effect of the present invention: this auxiliary support apparatus is one of longaxones parts visual plant on lathe during processing work, this device is arranged on the rear end of main spindle box, when workpiece overhangs longer through spindle through-hole, workpiece can be held, can float up and down along with the bending of workpiece again, workpiece, to the impact of carrying roller and carrying roller, the reaction force to workpiece reduces to Min., thus ensure that tube to tubesheet is in optimum state.Especially the outer loop material of backing roll is wear resistant nylon, can not damage while good holding workpieces to outer surface of workpiece.
Through force analysis, theory calculate, repetition test and long term production prove, this auxiliary support apparatus serviceability is good, high-quality product can be gone out with lathe accessory processing, can greatly enhance productivity, reduce labour intensity, shorten the clamping time, percent defective is low, and Technological adaptability is strong, and finished product uniformity is good, the requirement to workman's skills involved in the labour can be reduced, reduce production cost; Structure is simple, easily manufactured, is auxiliary support apparatus when desirable lathe being processed longaxones parts.
