Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing and have
The utility model is described in further detail for body embodiment.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of boring through lathe device, including chuck 501, centre frame 502, lathe tool
Frame 503, tail centre 504, collet 505, boring bar 506, boring cutter 507 and boring device.
Boring cutter 507 is fixedly mounted on 506 front end of boring bar, and boring device includes mounting rack 100 and at least two fasteners
200, it is keyed between mounting rack 100 and boring bar 506, branch fastener 200 is mounted on 100 lateral surface of mounting rack, is used to support workpiece
600 boring hole inner walls, at least two are uniformly distributed along boring bar 506 is circumferential.Branch fastener 200 uses three in the present embodiment.
To reduce the abrasion to 600 hole inner wall of bore hole workpiece, idler wheel 202, idler wheel are installed in the outer end of branch fastener 200
202 axis is parallel to 506 axis of boring bar.When chuck 501 and boring bar 506 relatively rotate, idler wheel 202 and to bore hole workpiece
Relative rolling occurs for 600 hole inner walls, eliminates the abrasion that branch fastener 200 treats 600 hole inner wall of bore hole workpiece.
Boring device further includes adjusting branch fastener 200 close to or far from the regulating mechanism of boring bar 506, and regulating mechanism includes lock
The bolt 400 of compact schemes head 200 and driving elastic component 300 of the branch fastener 200 far from boring bar 506 when bolt 400 is opened.Specifically
Ground, 100 lateral surface of mounting rack are equipped with the holding tank 103 radially extended along boring bar 506, and branch fastener 200 is movably located at receiving
In slot 103, elastic component 300 is placed between 103 bottom wall of 200 inner end of branch fastener and holding tank, and bolt 400 passes through on mounting rack 100
Threaded hole simultaneously abuts branch fastener 200.Elastic component 300 is compressed spring.
In the present embodiment, mounting rack 100 includes installation set 101 and strut 102.Installation set 101 is annular and is set in
It on boring bar 506, is keyed between installation set 101 and boring bar 506, to limit the rotation of mounting rack 100.Strut 102 is three
And it is circumferentially uniformly distributed along installation set 101, strut 102 is radially extended along installation set 101.Strut 102 and installation set 101 are made
One forms the triadius type structure of mounting rack 100.Holding tank 103 is located at 102 outer end end face of strut.
Branch fastener 200 is equipped with groove 201, and 400 front end of bolt passes through the threaded hole on mounting rack 100 and is embedded in groove
In 201.Tightening bolt 400 makes its abutting 201 bottom wall of groove that can fix branch fastener 200.Branch fastener 200 is in 201 side wall of groove
It is movable in a certain range always under cooperation with bolt 400, avoid branch fastener 200 from being detached from holding tank 103.
The boring cutter 507 of influence of the radial component to 506 moment of flexure of boring bar when to eliminate boring, this lathe 500 uses double cutting edge.
With 500 bore hole of this lathe, the dimensional accuracy in hole is processed completely by 507 Assurance of Size of boring cutter, reduces operating error.Boring cutter 507
It is divided into rough boring cutter and fine boring cutter.Rough boring cutter uses carbide chip, and welding structure, cutter is rigidly good, is conducive to select and cut greatly
Cut dosage.Fine boring cutter is insert structure, is convenient for reconditioning.It is machined with double bond slot in the centre bore of 507 cutter hub of boring cutter, is passed through
A pair of of flat key transmits torque.The centre bore is both 506 mounting hole of sharpening fabrication hole and boring bar, therefore needs very high size
Precision and low surface roughness.The axial line verticality of the both ends of the surface device to hole in hole also has strict demand.To can fully ensure that two
The symmetry of blade should whet a knife on universal cutter grinder.
Boring device is the critical component for carrying out bore hole, it is the machined surface by hole, by three-point support Fig. 1
The rigidity that 200 quantity of branch fastener is three to improve boring bar 506.
Boring bar collet 505 is made of shell and sliding sleeve two parts, is linked together with flat key, and axial direction is milled with a through slot,
Boring bar 506 can be clamped by bolt.The main function of boring bar collet 505 is to guarantee accurately determine when boring bar 506 vertically moves
To and positioning.
Before use, boring bar 506 to be held out against to two tops in 500 main shaft of lathe and tailstock by the centre bore at 506 both ends of boring bar
Between point, bounce with 506 cylindrical surface of amesdial centering boring bar to 500 axis of lathe, the circular runout of overall length is not greater than
0.01mm.Adjustment finishes, and boring bar collet 505 is pressed on lathe saddle 503.500 cross slide of lathe is locked, it is mobile longitudinal
Slide plate, knife rest dragging boring bar collet 505 are made to answer easily fluent sense when longitudinal sliding motion.
Mobile saddle, makes boring bar collet 505 close to mounting rack 100, screws the bolt on boring bar collet 505, press from both sides boring bar
Set 505 holds boring bar 506 tightly.The outer edge surface of three idler wheels 202 on mounting rack 100 is compressed to again and is slightly less than the straight of processed hole
Diameter and clamping screw 400.When boring cutter 507 enters processing hole, in the not yet access aperture of mounting rack 100, but at this moment due to boring bar 506
Jib-length is very short, the rigidity of boring bar 506 be it is enough, cutting vibration will not occur.Continue to feed, mounting rack 100, which enters, to be added
In work hole, feed-disabling, unclamps bolt 400 at this time, discharges idler wheel 202, is tightly pressed against the outer edge surface of idler wheel 202 machined
In hole face, screwing bolts 400 immediately, by 200 radial positioning of branch fastener.To prevent from scratching machined surface, idler wheel 202 is preferably selected
The softer and wear-resisting material production of quality, outer edge surface should have very low surface roughness.Unscrew the spiral shell on boring bar collet 505
Bolt, mobile 500 saddle of lathe, moves to 506 tail portion of boring bar for boring bar collet 505, makes the cantilevered out length in 506 head of boring bar slightly larger than institute
The depth dimensions of bore hole, then screwing bolts clamp boring bar 506, can continue to process.
Above embodiment does not constitute the restriction to the technical solution protection scope, any in above embodiment
Spirit and principle within made modifications, equivalent substitutions and improvements etc., should be included in the technical solution protection scope it
It is interior.
