Description
Technical field
The utility model relates to a kind of cutter for lathe or boring machine, is specifically related to a kind of micrometer adjustement boring tool structure.
Background technology
Boring cutter is the one of cutting tool for boring, be generally circle handle, also have larger workpiece user knife bar generally to see vertical car, the most frequently used occasion be exactly in hole machined, reaming, profiling etc.But be not hole in can only processing, angle head cylindrical also can be processed, not just such use traditionally.Boring cutter is indispensable important cutter in precision hole machining, the precision of its machining hole can reach IT6 level, surface roughness can reach Ra0.8 ~ 1.6 μm, and common pattern has screw-type micrometer adjustement boring tool, the small adjustment eccentric borer, chute-type double-blade boring cutter and floating boring tool etc.These micrometer adjustement boring tools differ from one another, and are used widely in actual production.
Use the required precision of boring cutter machining hole very high, so use in boring cutter stretch out boring bar amount require very accurate, existing boring cutter is normally fixed by the screw of boring bar side, when adjusting the overhang of boring cutter, screw is unscrewed, then adjust stretching out of boring cutter, after adjusting overhang, then use screw-driving.The overhang of said method adjustment boring cutter is difficult to hold, so the precision of machining hole is not high.
Utility model content
The micrometer adjustement boring tool structure that the purpose of this utility model is providing a kind of overhang of boring cutter easily to hold.
For achieving the above object, the technical solution of the utility model is as follows:
Micrometer adjustement boring tool structure, comprise boring cutter bar, cutter block and blade, described boring cutter bar is provided with the installing hole running through boring cutter bar, also be provided with taper accurate adjustment nut, stretching screw, thread segment is provided with in the middle part of described cutter block, cutter block is inserted in installing hole, and cutter block is connected with key between installing hole, boring cutter bar is stretched out in cutter block one end, described blade is arranged on cutter block and stretches out boring cutter bar one end, described taper accurate adjustment nut thread is connected on cutter block, and taper accurate adjustment nut and boring cutter bar inclined-plane offset, shoulder is provided with in described installing hole, described stretching screw is connected away from blade one end with cutter block, and stretching screw can be supported on described shoulder.
The principle of this programme: during installation, first cutter block one end is inserted in installing hole, and connect with key, be screwed on the thread segment of cutter block by taper accurate adjustment nut again, taper accurate adjustment nut and boring cutter bar inclined-plane offset, and then stretching screw are connected to cutter block away from blade one end, and stretching screw is supported on the shoulder in installing hole, turn taper accurate adjustment nut, the overhang of adjustment cutter block, is then strained cutter block by stretching screw.
The advantage of this programme is: cutter block is inserted in installing hole, and cutter block is connected with key between installing hole, so cutter block can not rotate relative to boring cutter bar, because taper accurate adjustment nut thread is connected on cutter block, and taper accurate adjustment nut and boring cutter bar inclined-plane offset, in addition, shoulder is provided with in installing hole, stretching screw is connected away from blade one end with cutter block, and stretching screw can be supported on described shoulder, cutter block is strained by stretching screw on the one hand, offseted by taper accurate adjustment nut and boring cutter bar inclined-plane on the other hand, both actings in conjunction thus cutter block is strained, when regulating the overhang of cutter block, unscrew stretching screw, then taper accurate adjustment nut is turned, just fine setting can be realized by taper accurate adjustment nut, the overhang of boring cutter is easily held.
Further, described boring cutter bar is provided with indicating graduation, and taper accurate adjustment nut is provided with adjustment scale.Unscrew stretching screw, then turn taper accurate adjustment nut, just can adjust the overhang of cutter block, now coordinated the adjustment scale of accurate adjustment nut by indicating graduation on boring cutter bar, just can very accurately indirect regulation cutter block overhang.
Further, pad is provided with between described stretching screw and shoulder.Tighten in the process of stretching screw, stretching screw can apply pressure and rub on shoulder, is provided with the wearing and tearing that pad can slow down slow shoulder, and can compensates the wearing and tearing of shoulder between stretching screw and shoulder.
Further, the tapering of described taper accurate adjustment nut is 1:2.Above-mentioned tapering is relatively large, boring cutter bar be applied on taper accurate adjustment nut to strain the contrary component in direction comparatively large with stretching screw, when tightening stretching screw, boring cutter bar can provide larger support force.
Further, described blade is connected with cutter block by bolt, and cutter block is provided with blade stop pin.Blade stop pin can prevent blade in blade use procedure from rotating.
Accompanying drawing explanation
