Description
Technical field
The utility model relates to a kind of for common boring machine, drilling machine, the bore hole boring clamp device of milling machine; Specifically a kind of general bore hole boring folder instrument.
Background technology
The boring folder boring head majority of prior art is special boring folder boring head; Complex structure, manufacturing cost is high, and maintenance cost is also high.Boring folder boring head is a kind of special forming tool, need carry out specialized designs according to the feature of concrete processing object, this be current be the most also the most practical way.Deep hole rough boring head Special cutter adopts carbide alloy, has two kinds of structures of welded type and clip type.Each deep hole machining series of cutting tools machine folder boring head, T-shaped deep hole be thick/forming tool of the boring folder boring heads such as fine boring head, combined boring head, the aperture can only machining specifying, like this, the forming tool that will press from both sides with the bore hole boring of different size in the aperture of processing different size; Thereby produce a large amount of material consumptions, waste a large amount of costs.Due to the rigidity difference of boring head housing in two faces of horizontal and vertical, affect the machining accuracy of fine boring machine.Under the effect of cutting force, boring head housing fills the cyclic deformation that therefore bearing place along the circumferential direction causes, has caused the turn error of main shaft.Although cutting force is very little when right boring, this distortion has reduced machining accuracy.Boring head generally comprises rigid boring head and rack sleeve guide pin bushing universal swing boring head, and boring cutter bar comprises rigidity knife bar and universal swing knife bar.Producing at present the upper boring head using has the structures such as nut transmission and centering type, but the adjustment precision of these boring heads is all not high enough, conventionally can only reach 0.01mm.A kind of boring head of Soviet Union development is by body, cutter holder, boring cutter, screw thread rotation set and be fixed on the parts such as dial on screw and form.Boring cutter is fixed by screws in cutter holder.On screw thread rotation set, be made with internal and external screw thread, its external screw thread is connected with cutter holder.T-shaped deep hole is thick/and the boring chuck of fine boring head adopts T-slot location, produces after wearing clearance at T-slot, and the gap of generation, affect bore hole precision, and the wearing clearance of T-slot generation is noncompensable.In Boring, especially while carrying out large quantities of a large amount of Boring on automatic assembly line, because wearing and tearing and other process conditions variation etc. of the wearing and tearing of cutter and adjustment, lathe are determined or the existence of uncertain factor, affect greatly quality, efficiency and the reliability of Boring.
Summary of the invention
The purpose of this utility model is the problem existing for above-mentioned prior art, provides a kind of simple in structure, and clamping is reliable, has the bore hole boring clamp device of versatility.
The utility model solves the technical solution that its technical problem adopts, a kind of general boring folder boring head, comprise rigid boring head body and Application of Mechanical Clamping Rigid Boring head rod, described boring head comprises screw thread rotation set and fixes the cutter holder of boring cutter by radial screw, boring head body is connected with cutter holder, boring head bar is axially fixed on boring head slide 4, it is characterized in that: cutter holder lower end step is shaped with trapezoidal guide runner 9, trapezoidal guide runner 9 is assemblied in the guide rail dovetail groove of boring head slide 3 inner chambers, with the adjusting screw(rod) 10 of dial and screw withstanding tight block 6, screwed hole by described boring head body 3 and trapezoidal guide runner 9 links together, boring cutter cutter is moved axially along adjusting screw(rod) 10, housing screw 5 by vertical adjusting screw rod 10 is fastening, realize the radius of gyration of accurate adjustment point of a knife.
The utility model has following beneficial effect than prior art.
Simple in structure, clamping is reliable.The utility model parts are few, adopt the housing screw 5 of vertical adjusting screw rod 10 fastening, locate by guide rail dovetail groove, have more positioning precision high; Bear axial force higher 1 times than existing bore hole boring chuck.Guide rail dovetail groove positioning precision is high.Producing after wearing clearance, under the condition that is subject to axial force, the wearing and tearing of guide rail dovetail groove locating latch pyramidal plane can compensate naturally.Thereby this bore hole boring chuck can be used for again the end face of boring piece surface and circular pieces.Low cost of manufacture, keeps in repair also easily, and particularly its structure is simpler than existing bore hole boring chuck, but can ensure processing aperture required precision.
There is versatility.The adjusting screw(rod) that the utility model links together by the screwed hole of boring head body and trapezoidal guide runner, can make boring cutter cutter move axially along adjusting screw(rod), realize the adjustable of the accurate adjustment point of a knife radius of gyration, can regulate boring folder boring head according to processed part pore size.
Lightweight; Easy for installation; Operator uses laborsaving.The utility model clamping the boring head slide of cutter and the boring head body linking together with shank, as long as be furnished with can installing of Mohs cone on lathe.Bore hole boring chuck has sufficient intensity, rigidity; Low cost of manufacture, operating maintenance is convenient.Employing the utility model more can be cost-saving, cuts the waste, and operating efficiency can improve 5 times.
The utility model is mainly used for common boring machine, drilling machine, and milling machine carrys out the bore hole boring clamp device of machining hole.
