The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Like Fig. 1～shown in Figure 5, lathe 1, main spindle box 2, lock cutter nut 3, four stations lean on grid 4, accurate end tooth index dial 5, workpiece 6, boring cutter 7; Anchor clamps 8 bore 11, No. three cutter heads 12 of 10, No. two cutter heads of 9, numbers cutter heads of cornish bit, alignment pin 13, the first cutter heads 14, screw 15; Screw 16, movable blade casket 17, roll adjustment screw 18, dial 19, adjusting rod 20, positioning sleeve 21, smart cornish bit 22, base 23; Rotating disk 24, base plate 25, spring 26, nut 27, steel ball 28, limited screw 29, the second cutter heads 30;
New technological flow is: 1. bore and ward off φ 16 holes, φ 35 holes, φ 55 holes (once-forming)---2. essence is warded off φ 35 holes, φ 55 holes (once warding off out)---3. polishing φ 35 holes---4. polishing φ 55 holes, simplifying is four procedures.Only introduce structure and use that 232M-3 rotor block two leans on dedicated tool and four stations grid below.
Boring cornish bit 9 is to utilize lock cutter nut (like figure four) connection boring machine main shaft and bore the cornish bit bar; Because there is the 3mm pitch difference in lock cutter nut 3 two ends screw threads; So handle of a knife is locked on the boring machine main shaft when lock cutter nut 3 turns clockwise, and then is pulled out on the contrary and can unloads.Special metals cutter head one and special metals cutter head two each two is housed on the knife bar, fixes and symmetry knife bar top welding E216, one of YG6 cutter head with screw.Five cutter heads are together participated in cutting during cut, the stepped hole one-shot forming.
Smart cornish bit 22 is wanted directed and is installed, and coupling method is the same with brill cornish bit 9, is to utilize lock cutter nut 3 to connect boring machine main shaft and smart cornish bit bar.Because ward off out simultaneously in φ 35 holes, φ 55 holes,, there are two cover trimming assemblies to control the size in two holes respectively so two right boring cutter heads are housed on the smart cornish bit bar.Smart cornish bit trimming assembly principle is: four pieces of M2 countersunk head screws are dial 19 fixedly; Dial 19 drives adjusting rod 20 rotations; Adjusting rod 20 drives 18 rotations of roll adjustment screw, and moving of cutter head accomplished trimming movement on roll adjustment screw 18 drive movable blade caskets 17 and the movable blade casket 17.Alignment pin 13 is to prevent that the cutter casket from rotating usefulness, and holding screw is to compress cutter casket usefulness, and cutter head is to be fixed by the M2.5 countersunk head screw.Because roll adjustment screw 18 two ends pitch differences are 0.25mm; Just move 0.25mm so dial turns around, because trimming assembly is 30 ° of installations, dial 19 1 circles are carved with 25 lattice; This just makes dial 19 clockwise rotate lattice, and radial direction moves 0.005mm.Cutter head is selected into volume production U4-8004L-EK10N numerical control blade for use.
It is to be fixed on the lathe bed with screw, taper pin that four stations lean on grid 4, and spot welding base plate 25 and base 23 binding sites make it firmly also horizontal, refill compression spring, steel ball 28, rotating disk 24 and mandrel, mix screw, nut 27 as required.Clockwise rotate rotating disk 1/4 circle during use, just have a hole down (because a circle has four screwed hole through holes to be uniformly distributed with, rotate 1/4 circle after, spring promotes steel ball and falls into the hole automatically and locate, and with sound.) withstood the depth of being bored a hole on the length of the screw decision workpiece in the screw by steel ball 28 and spring 26.The every M10 screw of installing on the rotating disk, corresponding one the depth of cutter with hole on the control processing work.The adjustment of the length of screw is according to the Tool in Cutting workpiece during to the figure paper size, and rotating disk 24 is to the distance decision between machine tool dragging plate, when the M10 screw crown during to planker with M10 nut lock screw on rotating disk 24, prevent that screw from becoming flexible.Will rotate rotating disk 24 whenever changing one during cutter, make below its corresponding screw forwards to.When lathe cuts the feeding excess of stroke, lean on grid can withstand planker, force the feed of lathe to stop, preventing to cut the workpiece that causes and scrap.
The calibration of accurate end tooth index dial; The control crank that has handle ball forwards the left end (throw-out-of clutch of dial counterclockwise to; Workbench rises 2～3mm) time; Can stir table top calibration (position of changing a job) with hand turns to arbitrarily; Behind the graduation mark that the pointer aligning needs; With operating grip oppositely forward to clockwise tuning drive gear the right-hand member locked position (clutches engaged, table top descend again about 2～3mm) reach calibration quick with no gap, location purpose after, get final product the size and the position of related features of workpiece loading and unloading or processing work or measurement, metering workpiece.
