Description
Technical field
The utility model relates to the machined into technology, especially relates to a kind of borer.
Background technology
Often run into part as shown in Figure 1 aborning, need the bore dia difference of processing, and broad in the middle, and two is little.Not difficult with universal cutter processing on lathe, but the lathe specification that needs is very big, on big lathe processing very uneconomical, working (machining) efficiency is low, the processing cost height.Make special plane or adopt machining center machine tooling investment big, the cycle is long.Therefore be necessary the design specialized cutter, this part can be processed, on common vertical knee-type milling machine to cut down finished cost.
The utility model content
In order to address the above problem, the utility model provides a kind of borer.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
Borer, comprise an operator bar, the cylindrical of described operator bar is provided with the control nut of rotatable propelling, be provided with pushing ring near control nut below, the control nut promotes this pushing ring and moves, axially be provided with through hole in operator bar inside along it, be provided with the tapering pushing ram in this through hole, axially be provided with spring along the tapering pushing ram, spring one end is connected in the afterbody of tapering pushing ram, the other end is connected in the operator bar, the afterbody of tapering pushing ram is connected in pushing ring by advancing battle pin, and the operator bar is provided with to make and advances battle pin along the axially movable slotted hole of operator bar, and the conical nose of tapering pushing ram is near the afterbody of cutting knife bar, the cutting knife bar is by being connected in the operator bar along its spring that axially is provided with, and its head stretches out outside the operator bar.
Described tapering pushing ram and cutting knife bar portion are not provided with block, and spring is connected on the block.
Described cutting knife bar afterbody is spherical.
Described operator bar is provided with the tapered end that is used to connect machine tool chief axis.
The beneficial effects of the utility model are, this borer has solved the processing problems on upright drill processing hole small in the end and big in the middle, also can on upright drill, finish processing to the hole internal channel, finish the machining functions that only on main equipment, just can finish on the mini-plant, enlarge the scope of application of lathe, reduced processing cost.
Description of drawings
Fig. 1 is the part schematic diagram that the borer that the utility model proposes is processed;
Fig. 2 is the structural representation of the borer that the utility model proposes.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 2, the borer that the utility model proposes comprises operator bar 100, the cylindrical of described operator bar 100 is provided with the control nut 200 of rotatable propelling, be provided with pushing ring 210 near control nut 200 belows, control nut 200 promotes this pushing ring 210 and moves, axially be provided with through hole 110 in operator bar 100 inside along it, be provided with tapering pushing ram 220 in this through hole 110, axially be provided with spring 310 along tapering pushing ram 220, tapering pushing ram 220 afterbodys are provided with block 311, spring 310 is connected on the block 311, the other end is connected in operator bar 100, cover plate 312 is closed in spring 310 in the operator bar 100, the afterbody of tapering pushing ram 220 is connected in pushing ring 210 by advancing battle pin 211, operator bar 100 is provided with to make and advances battle pin 211 along operator bar 100 axially movable slotted holes 120, the conical nose 221 of tapering pushing ram 220 is near the afterbody of cutting knife bar 230, cutting knife bar 230 is by being connected in the operator bar along its spring 320 that axially is provided with, its head stretches out outside the operator bar, the afterbody of cutting knife bar 230 is provided with block 321, spring 320 is connected on the block 321, and cover plate 322 is closed in spring 320 in the operator bar 100.The afterbody 231 of cutting knife bar 230 is spherical.Described operator bar is provided with the tapered end 130 that is used to connect machine tool chief axis.
Pushing ring 210 keeps contacting with control nut 200 under spring 310 effects, operator bar 100 cylindricals have one section screw thread, cooperate with control nut 200, rotating control nut 200 can allow pushing ring 210 move down, when moving axially, pushing ring 210 moves axially by advancing battle pin 211 to drive tapering pushing ram 220, the conical nose 221 of tapering pushing ram 220 promotes cutting knife bar 230 and outwards moves when moving down, and realizes feed; When controlling nut 200 to counter-rotation, under the effect of spring 310, by block 311 tapering pushing ram 220 is moved up, and by advancing battle pin 211 drive pushing rings 210 to move upward, be close to control nut 200, when tapering pushing ram 220 moves up, under the effect of spring 320, by spring block 321 will cut knife bar 230 to rollback and and tapering pushing ram 220 be close to, finish withdrawing.
During use, start lathe (at a slow speed), move down machine tool chief axis and move to the position that needs together, rotate the feed of control nut with cutter, according to scale, can control depth of cut, finish the feed process, lathe changes normal speed over to and finishes processing, and backward rotation control nut is finished withdrawing then.
This borer has solved the processing problems on upright drill processing hole small in the end and big in the middle, also can on upright drill, finish processing to the hole internal channel, finish the machining functions that only on main equipment, just can finish on the mini-plant, enlarge the scope of application of lathe, reduced processing cost.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
