Description
What the present invention relates to is machining equipment, particularly a kind of head of long-tube or long-axle parts machine-tool for comprehensively machining.
Be unable to do without various mechanical processing machines in the machine-building, it can finish outer garden, the endoporus of part, the processing of end face, can also finish the processing of tapering, screw thread, chamfering, head of long-tube or long-axle parts often also needs to process outer garden, endoporus, end face chamfering, tapering, straight thread, taper thread etc.For example, oil pipe, tracheae, oil drill rocker taper thread, the oil pipe of production tree and the connecting thread of oil production equipment etc. are because the oversize general lathe of part is difficult to finish.
Also have in the prior art and can finish the mach special equipment of head of long-tube or long-axle parts, for example, die head threading machine, beveler, end face cutting machine etc.Their most function singlenesses, the processing request that can reach is low, and the caliber and the diameter of axle are all less.Also has non-traditional machine tool in the prior art at long-tube or long-axle, for example, the processing petroleum pipeline, the long tube lathe of drilling rod, heavy caliber pipe end chamfering machine etc., they generally are how long pipe has, lathe just has much, and complex structure is bulky, involve great expense, can not adapt to the needs of field work.Chinese patent has been announced a kind of Pipe mouth lathe (patent No. is 90201038), and it can finish the processing such as outer garden, endoporus, tapering, straight thread, taper thread chamfering of pipe end, but its poor rigidity, transmission is unreasonable, can only be a kind of illustrative structure.
The objective of the invention is to propose that a kind of volume is little, in light weight, cost is low, can finish the machine-tool for comprehensively machining of the various processing requests of head of long-tube or long-axle parts.
The present invention realizes like this.It comprises frame, clamping device, holding device, feed screw nut's axial feed system, radial tool post, radially feeding system, swivel mount, headstock.One end of frame is equipped with clamping device, the other end feed screw that is connected, the female silk of one feeding is contained in the head of screw mandrel: be with a hollow shaft that can only slide and can not rotate on screw mandrel, the housing of swivel mount passes through two place's bearing holder (housing, cover)s on hollow shaft, housing one end of swivel mount is equipped with one or more radial tool posts of doing radial motion, links to each other with headstock by power gear, splined shaft on the other end; Install a central gear on the hollow shaft, one or more groups feed gear wheel and change gear are installed between central gear and the female silk of feeding, one or more groups feed gear and change gear are installed between the feed screw mandrel of central gear and radial tool post, every group of feeding change gear is provided with a clutch, and every group of feed change gear also is provided with a clutch.
Clamping device is used for clamping to be processed pipe end (or axle head), and is firm for accurate positioning, two covers can be set clamp device.
The course of work of the present invention is such.Use the clamping device clamping work pieces, when the power of headstock makes the swivel mount rotation by power gear, feed gear wheel group and gear changing group by with hollow shaft on the engagement of central gear, the form that promptly becomes the NW Gear Planet Transmission drives female silk and rotates on screw mandrel, thereby finishes the action that axially feeds of swivel mount.Thereby feed gear train and gear changing group drive the feed screw mandrel rotation (not having the planet effect this moment) of feed support by the engagement of the central gear on the hollow shaft finish radially feed.

Disconnect the feed gear changing group, connect the axial feed gear changing group, when swivel mount rotates, drive the radial tool post rotation and make axial feed, on radial tool post, load onto suitable cutter, then can finish processing of outer garden and straight thread processing.The speed ratio that changes the feeding gear changing group can change axial feed velocity.
2, processing end face.Disconnect the axial feed gear changing group, connect the feed gear changing group, when swivel mount rotates, drive the radial tool post rotation, the cutter on the radial tool post is made radial feed, loads onto suitable cutter on radial tool post, then can finish the work of end face processing.
3, the outer garden of processing tapering, tapering endoporus and taper thread.
Connect the feeding gear changing group, connect radially feed gear changing group simultaneously, on radial tool post, load onto suitable cutter, when swivel mount rotates, this cutter is also finished radial motion when finishing axially-movable, axially reach the ratio of radial motion according to the appropriate change that requires of tapering, thereby finish the outer garden of various taperings, the processing of tapering endoporus and taper thread.
4, chamfering, beat groove.
It is the special case of tapering processing.Connect axial feed gear changing group and radially feed gear changing group simultaneously,, adjust the axial feed and the ratio of feed radially, can process by the requirement that chamfering is beaten groove.
5, the present invention can adopt screw die of the prior art or screw tap to process various screw threads when processing path pipe fitting.
In order to increase the processing rigidity, be provided with an external threading holding device in the present invention's feed screw: swivel mount is provided with one with cutter garden dish, is provided with the follow-rest that three energy move on the garden on the guide rail on the frame outside with cutter garden dish.
