Description

A kind of deep hole rig
Technical field
The invention belongs to the drilling process equipment of machining, specifically a kind of deep hole rig.
Background technology
The drilling processing in hole is the common manufacturing procedure of machining, and corresponding equipment has platform drill, highwall-drilling machine, added The hole depth of work is substantially 5 times of aperture or so, but also may require that processing sometimes.Hole depth/aperture is more than 5-30 times and is commonly called as depth The processing in hole, the processing of this pores is substantially by the way of classification is bored, and getting into one section of depth needs to change drilling tool, and work consuming takes Not very, depths is more got into, the swing of drill bit is bigger, and hole the more is bored the more inclined, and also iron filings discharge is difficult, workpiece, iron filings, the mill of drill bit Damaging and rub and be increasingly severe, caused heat is not easy to discharge again, and result is that bit life is short, and machining accuracy is low, and operation is loaded down with trivial details, Efficiency is low.Chinese patent:Authorization Notice No. CN201815705U, title《A kind of handstand depth drill》.A kind of drill bit is disclosed to fall Vertical installation, drill bit be special hog nose, drill bit can be cooled down with hydraulic oil, iron filings easily discharge, fixture from hole Only turn round, and the equipment and technology scheme for deep hole machining that workpiece is run up and down by screw mandrel along guide rail.But still suffer from cooling Hydraulic oil is needed, because the centripetal force center line of application, drilling axial force and guide rail center of gravity, rail friction power are misaligned, easily production Raw torque, cause to process axially bored line deflection, and workpiece does not rotate, and can not correct deflection, the radial accuracy of hole machined is not high, production Rate is low, and big scale of construction workpiece feeding inertia is big, the shortcomings that making cutter rapid wear.
The content of the invention
It is an object of the invention to overcome above the shortcomings of the prior art, there is provided a kind of drill bit stands upside down to install and both rotated Also the deep hole rig that operation, workpiece and drilling tool rotate against up and down.
Realize that purpose of the present invention technical scheme is:A kind of deep hole rig, including fuselage, inverted drilling tool, fixture, top Bar, transmission mechanism, described fuselage are provided with guide rail and the drilling tool connecting platform to be moved up and down along guide rail, push rod connecting platform, consolidated Fixed upper mounting plate, the lower platform of fixation and fixed work piece platform between drilling tool connecting platform and push rod connecting platform, is passed Motivation structure has spindle drive, fixture transmission mechanism, push rod transmission mechanism and feeding drive mechanism, spindle drive connection On lower platform, push rod transmission mechanism is connected on upper mounting plate, and drill spindle head is connected on drilling tool connecting platform and blocks drilling tool Driven and rotated by spindle drive, push rod tip is connected to downwards on push rod connecting platform to be driven up and down by push rod transmission mechanism Run, idle station is connected in work piece platform to be driven by fixture transmission mechanism and rotated with drilling tool relative direction upward in clamp shaft , drilling tool connecting platform drives enforcement drilling tool to arrive at workpiece through clamp shaft vestibule and carries out drilling by feeding drive mechanism, under Row is exited, and feeding drive mechanism is made up of platform lifting device, clutch, decelerator, motor, and platform lifting device is by hand Wheel, feed shaftPull element is formed, and it is connected to drilling tool connecting platform makes lifting process stress balance symmetrical in both sides up and down;
Above-mentioned fixture can also be equipped with top formula drill jig, and drill jig hole is located at the fixture centre of gyration;
Above-mentioned spindle drive can be made up of spindle motor, main shaft, spline pair, and motor connection is pressed from both sides on fuselage Tool transmission mechanism is by clamp shaft, speed reducing transmission case, motor is formed, speed reducing transmission case, motor are arranged in work piece platform, push rod Transmission mechanism forms push rod speed reducing transmission case by revolution push rod, push rod screw pair, push rod speed reducing transmission case, motor, motor connects It is connected on upper mounting plate, feeding drive mechanism is made up of drilling tool connecting platform lowering or hoisting gear, clutch, decelerator, motor;
Above-mentioned fuselage can be headframe type or planer-type;
The support column or planer-type fuselage column of above-mentioned headframe type fuselage can also be drilling tool connecting platform, push rod connection The guide rail of platform;
The pull element of above-mentioned platform lifting device is arranged in pairs, and it includes driving wheel, driven pulley, feeding chain, chain Connector, feed shaft, clutch, decelerator, motor are set on the stationary platform, and motor connection decelerator is driven by clutch Feed shaft rotates, and driving wheel is on feed shaft, and driven pulley is loaded in fixed platform and workbench, and feeding chain is around actively Wheel, driven pulley both ends pull the both sides of workbench with chain connector connection, and handwheel is connected to feeding shaft end;
The main shaft head end of above-mentioned spindle drive is also provided with getting rid of bits disk.
The present invention a kind of deep hole rig, drill bit stand upside down installation both rotary motion and also feed operation, workpiece then only with drilling tool The structure of relative rotary motion, drill speed reduces under conditions of making identical processing efficiency, and the centrifugal force of chip reduces, with hole wall Frictional force reduces, and chip accelerates discharge close to the speed of freely falling body, hence it is evident that improves drill bit temperature because caused by radiating is bad Degree rise, decrease abrasion and extend the life-span, drilling tool rotates against simultaneously with workpiece makes cutting point position be become by fixation Rotate in a circumferential direction change, eliminates because of journal offset and vibration caused by radial load effect, in the positive and negative drawing synchronization of feed mechanism Bottom offset, it ensure that the running of drilling tool feeding platform is parallel up and down, make 1. to feed center line with joint efforts, 2. feed mechanism geometry Center, 3. rail friction make a concerted effort center, 4. drilling tool rotation centerline, 5. workpiece hole rotation centerline to be processed, in same axle On extended line, meet the abbe's principle in Precision Machinery Design.Drilling tool is set not swung vertically when feeding, so as to improve processing essence Degree, and fluted drill drilling can be used.
