Abstract

The invention discloses deep hole processing equipment capable of realizing boring, drilling, pulling and milling on one piece of equipment. Front and back two groups of worm and gear mechanisms are adopted, and a spiral combination and axial sliding fit together with a screw rod shaft provided with a guide groove is constructed through a nut and a guide sliding key at the central position of a worm wheel respectively; an inner sleeve, a guide sleeve and a guide sliding key are arranged in a front worm wheel inner hole; a guide sliding key is in sliding fit with the guide groove on the screw rod shaft; an inner sleeve, a connecting sleeve and a nut are arranged in a back worm wheel inner hole; and the nut and the screw rod shaft form a spiral combination. Advancing, retreating, rotation, positioning and indexing of the screw rod shaft are realized through relative movement from stillness to low speed to high speed rotation and mutual action of the two groups of worm and gear mechanisms. A connecting shaft head at the front end of the screw rod shaft is used for installing boring, drilling, pulling and milling mechanisms. During processing of super long deep hole workpieces, the screw rod shaft can be lengthened in a butt joint way by connecting a preserved hole with the tail end of the screw rod shaft.

Description

Deep-hole boring, bore, draw, grind multifunctional process equipment

One, technical field

The present invention relates to a kind of equipment that can carry out deep-hole boring, bore, draw, grind multi-functional processing, belong to mechanical manufacturing field.

Two, background technology

At present, known deep hole processing equipment is mostly boring, bores, draws, grinds respective autonomous device, although existing boring machine has possessed boring, bored working ability, under many circumstances, can not meet the demand of deep hole machining very well.Single right with regard to deep hole machining, the main cause affecting its operating efficiency and geometric accuracy is after processing this procedure of deep hole, also to move to after broaching machine or grinding machine carry out secondary centering and reprocess, longer deep hole machining part is difficult to the home position state after returning to first processing when carrying out second time centering, so namely, directly affects the geometric accuracy of back of the body processing, have influence on operating efficiency again simultaneously.

Three, summary of the invention

In order to overcome existing boring, bore, draw, limitation that mill equipment is processed separately respectively, the invention provides one and utilize two groups of worm and gear combined mechanisms, same equipment realizes boring, bores, draw, grind the multifunctional equipment of deep hole machining.

The present invention solves the technical scheme that its technical problem takes; Boring bar, ' deep hole pull bar and bistrique all adopt the same filament bar axle as the stretching in main spindle box and rotary main shaft to drilling rod, gathering sill is processed with in screw axis side, gathering sill length and screw axis are with long, be shaped with connection preformed hole at the tail end of screw axis, be processed in its front end and boring can be installed, bore, draw the connection spindle nose with grinding head mechanism.Two groups of worm-and-wheel gears in main spindle box, install in tandem along coaxial direction, at front worm gear endoporus, inner sleeve, fairlead, feather key are housed, gathering sill on feather key and screw axis is slidably matched, rear worm wheel endoporus is equipped with inner sleeve, adapter sleeve and nut, and nut and screw axis form spiral and combine.This nut makes screw axis do to advance and the motion retreated by worm gear wheel, the rotation of front worm gear and static, achieves the rotation of screw axis, calibration and location by feather key.The rotation of two worm gears is realized by the rotation of two worm screws respectively, and the rotation of two worm screws is driven respectively by two of main spindle box lateral surface groups of gear-boxes, and independently variable frequency drive motors installed separately respectively by two groups of gear-boxes.

The invention has the beneficial effects as follows; By two groups of worm-and-wheel gears separately respectively by static, low speed to High Rotation Speed relative motion, interacting realizes advance and the retrogressing of screw axis, rotate, locate and calibration, thus realize boring, bore, draw the deep hole processing technology of mill, because processed workpiece is processed into finished product on same equipment, effectively can improve the machining accuracy of workpiece, increase work efficiency, when processing super long deep hole workpiece time, preformed hole can be connected by screw axis tail end and screw axis docking is lengthened.
