Description
Technical field
What the portable disc boring machine of the present invention related to is a kind of cut machinery that on-the-spot online flange, valve and burning are chewed of repairing.The flange, valve and the Coal Chemical Industry that are specially adapted on on-the-spot pipeline of petroleum chemical enterprise or the pressure vessel are burnt the cut work of chewing.
Background technology
At present, existing field machining facility function ratio is more single, and machining accuracy is not ideal.Though, a kind of field machining disc machine is arranged, only can facing, can not the taper turning face, the boring endoporus, and have only a kind of feed velocity.During the rotation of this machine, rotating disk is to lean on several groups of rolling bearings to be pressed in to keep on the circuit orbit its circular motion, because of being that gap or preload pressure between several groups of bearings it and the circuit orbit is difficult to the adjustment unanimity.Therefore, the machine rigidity is poor, and weight will weigh, and the chip surface roughness is difficult to desirable.Again because of be several groups of bearing roll extrusion on circuit orbit, each is organized bearing the pressure of track is not quite similar, the wearing and tearing that the track attrition surface produces are also inequality, service time is long slightly, accuracy of machines can descend.For the processing reparation of Coal Chemical Industry burner, must use multiple machine toolings such as lathe, boring machine to accomplish.
Summary of the invention
The present invention seeks to provides a kind of portable disc boring machine to above-mentioned weak point; Form by disk mechanism, delivering gear, bite governor motion, clamping mechanism etc., but compact conformation, good rigidly, can the various machined surfaces of how fast feed smear metal, the power source continuously variable; Therefore machining accuracy is high, roughness is good, easy for operation; Because of axial dimension is little, can in narrow space, work, the scope of application is extensive; Be a kind of cut machinery that on-the-spot online flange, valve and burning are chewed of repairing.
Portable disc boring machine is to take following technical scheme to realize:
Portable disc boring machine is made up of power source, disk mechanism, delivering gear, bite governor motion, clamping mechanism.
Disk mechanism is made up of disk tooth axle, casing, upper bearing (metal) sheet, anti-attrition thing; Disk tooth axle clamping is between upper bearing (metal) sheet and bottom of shell; And the anti-attrition thing is housed is separated by; Upper bearing (metal) sheet and shell are threads engaged, are used to regulate gap and pressure, and disk tooth axle and bearing shell are housed in upper bearing (metal) sheet and the casing.
Power source is installed in casing one side, on the power source output shaft driving gear is installed, and driving gear is meshed with disk tooth axle.
Delivering gear comprises feed gear, feed change gear, perpendicular drive link, break-in case, horizontal drive link, knife rest gearbox and crossbeam.Crossbeam is installed in disk tooth axle top.Knife rest gearbox and break-in case are installed on the crossbeam.In the said knife rest gearbox change pulley is arranged, the knife rest gear box output end is equipped with pinion.On the knife rest gearbox planker is housed, lathe tool is housed on the planker, planker can 360 ° of rotations on the knife rest gearbox.Said planker is provided with tooth bar, and the pinion that the knife rest gear box output end is equipped with is meshed with tooth bar.The feed toothholder is installed in casing one side; Feed change gear is installed on the feed toothholder through gear lever, and feed change gear is mounted on the feed toothholder fixed, and the feed change gear flank of tooth is a polygon; The number of teeth on each limit does not wait; This feed pinion stand is to variable, and crossbeam is mounted in disk tooth axle top, and feed gear, break-in case etc. all are contained on the crossbeam.
When machine run, disk tooth axle, crossbeam, feed gear all rotate, when the feed gear forwards fixed feed change gear to; Feed gear and feed change gear engagement rotation, the perpendicular drive link that is attached thereto, break-in case, horizontal drive link, knife rest gearbox all move, and planker moves; Lathe tool carries out smear metal; Continuous in succession, when change the feed change gear seat to, promptly change feed velocity.
Left bevel gear, right bevel gear and bevel gear are housed in the break-in case; Left bevel gear, right bevel gear are contained on the horizontal drive link, and bevel gear is contained on the perpendicular drive link, and the feed gear is installed in perpendicular drive link bottom; Stir left bevel gear, right bevel gear and bevel gear engagement respectively, i.e. change turns to.
The feed change gear end face is a polygon, and all there is one section gear on each limit, but the number of teeth does not wait.Change the change-speed gearing seat and change total number of teeth in engagement to promptly, and change the depth of cut, the feed toothholder is arranged under the feed change gear; And the spring tension is arranged, as long as feed change gear is extracted the feed toothholder, turn to through gear lever; Turn back to the feed toothholder again, the feed change gear direction changes, and the depth of cut promptly becomes.On the said feed toothholder spring is housed, so that buffering.
The bite governor motion is regulated seat, handwheel and screw mandrel by bite and is formed, and bite is regulated seat and is installed on the crossbeam, and bite is regulated screw mandrel is installed, and screw mandrel links to each other with screw thread with the knife rest gearbox, and handwheel is equipped with in the screw mandrel end.Because of planker on the knife rest gearbox of the present invention can 360 ° of rotations, dimension, but facing and taper seat at any angle, complete autofeed during smear metal, but during each smear metal, consider the bite size, and design this mechanism.Bite is regulated seat and all can on crossbeam, be slided with the knife rest gearbox, be to regulate lathe tool bite size, elder generation lathe tool to good workpiece; Regulating the seat lower screw to bite then tightens; Rotate handwheel and screw mandrel again, because of screw mandrel links to each other with screw thread with the knife rest gearbox, therefore; The knife rest gearbox rotates by the screw mandrel pulling because of handwheel, and sets up lathe tool bite size.
