Abstract
The invention relates to a swinging-adjustment type floating knife rest, comprising a sliding seat, a knife-rest swinging block, a swinging shaft and a sliding block, wherein the two ends of the sliding seat are respectively arranged on sliding rails of a knife disc through the the sliding block to form a sliding seat mechanism; the knife-rest swinging block is provided with a knife-tool installing hole, a swinging-shaft installing hole and a guide-shaft installing hole; the knife-rest swinging block is arranged on the swinging shaft by a rolling bearing arranged in the swinging-shaft installing hole; the swinging shaft is arranged on the sliding seat; the knife-rest swinging block, the rolling bearing and the swinging shaft form the swinging mechanism; the guide shaft and a groove knife tool are respectively arranged in the guide-shaft installing hole and the knife-tool installing hole; and the guide shaft is arranged in the guide-shaft installing hole by the rolling bearing. The swinging-adjustment type floating knife rest has the advantages that grooves inside and outside a pipe piece can be turned, so that the problems that since the wall thickness of the pipe piece is not uniform and the shape is irregular, the grooves of the processed pipe piece are not uniform and the wall thickness error is larger and the like can be solved, and the quality and the accuracy of the grooves of the pipe piece can be improved.
Description
technical field:
The present invention relates to a kind of lathe cutter saddle, being specifically related to one can at lathe, milling machine, the floating tool holder that beveling machine uses.
background technology:
In machine tooling, pipeline-like part groove is the most common, for the processing of pipe fitting groove, general is all carry out on lathe, and existing tube groove lathe, its cutter head structure directly on cutterhead, installs two tool rests, tool rest can adjust according to the diameter will processing pipe fitting apart from the distance of cutter head center, those regular shape are processed with such knife rest, the large-caliber pipe fittings of uniform wall thickness can meet the processing request of pipe bevel, if irregular with such knife rest machining shape, the large-caliber pipe fittings that wall unevenness is even, processed rear tubular member is often made to occur that groove is uneven, the problems such as wall thickness deflection is larger, the processing request of pipe bevel can not be met.
summary of the invention:
For above-mentioned problems of the prior art, the object of the present invention is to provide a kind of oscillation adjustment formula floating tool holder, during the large-caliber pipe fittings that it is irregular at machining shape, wall unevenness is even, meet processing request.Improve groove quality and the precision of pipe fitting.
The technical scheme that the present invention takes for realizing its object: a kind of oscillation adjustment formula floating tool holder, comprises slide, knife rest swinging block, swinging axle and slide block, the two ends of described slide are arranged on the slide rail on cutterhead respectively by slide block, form a slide carriage mechanism; Described knife rest swinging block is provided with Cutting tool installation manner hole, swinging axle installing hole and guide shaft installing hole, described knife rest swinging block is arranged on swinging axle by the rolling bearing be located in swinging axle installing hole, described swinging axle is arranged on slide, and knife rest swinging block, rolling bearing and swinging axle form swing mechanism; Described guide shaft and groove cutter are arranged in guide shaft installing hole and Cutting tool installation manner hole respectively, and wherein guide shaft is located in guide shaft installing hole by rolling bearing.
The lower end of described swinging axle is fixedly mounted on slide by holding screw, prevents swinging axle and slide from relatively rotating.
Described rolling bearing adopts conical bearing.
beneficial effect of the present invention:can groove inside and outside car pipe fitting, solve because tube wall thickness is uneven, there is the problems such as groove is uneven, wall thickness deflection is larger in the processing rear tubular member that out-of-shape causes, improves retaining wall on slope quality and the precision of pipe fitting.

detailed description of the invention:
As Fig. 1,2,3, shown in 4, the present invention includes slide 2 and knife rest swinging block 3, knife rest swinging block 3 is longitudinally provided with three installing holes, i.e. Cutting tool installation manner hole, swinging axle installing hole and guide shaft installing hole; Knife rest swinging block 3 is linked together with swinging axle 4 by swinging axle installing hole and rolling bearing 5, forms a swing mechanism.In the guide shaft installing hole in face on the lower, the centre that guide shaft 11 is arranged on knife rest swinging block 3 by bearing; Groove cutter 17 is fixed in the Cutting tool installation manner hole of in the middle of knife rest swinging block 3 top by blade row trip bolt 16.Slide 2 establishes slide installing hole, and slide 2 is connected with slide block 15 by bolt, and slide block 15 is arranged on the slide rail 20 of cutterhead 19, forms a slide mechanism, slide block can be made to move on the slide rail 20 of cutterhead 19 or fix by adjusting bolt degree of tightness.Knife rest swinging block 3 can rotate around swinging axle 4.The lower end of swinging axle 4 is arranged on slide 2, and fixes with holding screw, prevents swinging axle 4 and slide 2 from relatively rotating.Rolling bearing adopts conical bearing, can prevent pipe bevel from adding the axial force produced man-hour.
Operation principle of the present invention: for the outer retaining wall on slope of pipe fitting, cutterhead 19 rotates, slide 2 fixed thereon is along with rotation, now the periphery of guide shaft 11 is adjacent to the inwall of processed pipe fitting 18, if processed pipe fitting regular shape (being circular) at this moment knife rest swinging block 3 can not be rotated around swinging axle 4, outer groove cutter 17 is apart from the invariant position of cutter head center, and the pipe bevel after processing is even.If processed pipe fitting out-of-shape (be not circular), at this time the inwall of processed pipe fitting 18 can produce a radial active force to guide shaft 11, thus makes guide shaft 11 be with movable knife rack swinging block 3 to rotate around swinging axle 4; This just makes outer groove cutter 17 apart from the position of cutter head center along with the radius change of processed pipe fitting, and in cutterhead 19 rotary course, the periphery of guide shaft 11 againsts the inwall of processed pipe fitting 18 all the time; Guide shaft 11 is determined with the relative position of outer groove cutter 17, and outer groove cutter 17 completes the outer groove processing to pipe fitting in the rotary course of slide 2.When therefore carrying out the inside and outside retaining wall on slope of pipe fitting with this floating tool holder, can make the pipe bevel after processing, uniform wall thickness, error is little, and precision is high.
According to the diameter of pipe fitting to be processed during use, by regulating the slide block 15 of the floating tool holder on cutterhead 19, whole floating tool holder is fixed on the correct position of cutterhead 19.
Above are only embodiments of the invention, to one skilled in the art, the present invention has multiple change and change.Allly within invention thought of the present invention and principle, make any amendment, equivalently to replace, improve, all should be included within protection scope of the present invention.
