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, be specifically related to a kind of can be at lathe, milling machine, the floating tool holder that uses on the beveling machine.
Background technology:
In machine tooling, pipeline-like part groove is the most common, processing for the pipe fitting groove, generally all be to carry out at lathe, and existing tube groove lathe, its cutter head structure is directly at cutterhead two tool rests to be installed, tool rest can be adjusted according to the diameter that will process pipe fitting apart from the distance at cutterhead center, process those regular shape with such knife rest, the uniform large-caliber pipe fittings of wall thickness can satisfy the processing request of pipe bevel, if irregular with such knife rest machining shape, the large-caliber pipe fittings that wall unevenness is even, tend to make processed rear tubular member groove to occur inhomogeneous, the problems such as wall thickness deflection is larger can not satisfy the processing request of pipe bevel.
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, satisfy processing request during it is irregular at machining shape, wall unevenness is even large-caliber pipe fittings.Improve groove quality and the precision of pipe fitting.
The present invention is the technical scheme that its purpose of realization is taked: a kind of oscillation adjustment formula floating tool holder, comprise slide, knife rest swinging block, swinging axle and slide block, and the two ends of described slide are installed on the slide rail on the cutterhead by slide block respectively, consist of 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 installed on the swinging axle by the rolling bearing of being located in the swinging axle installing hole, described swinging axle is installed on the slide, and knife rest swinging block, rolling bearing and swinging axle consist of swing mechanism; Described guide shaft and groove cutter are installed in respectively in guide shaft installing hole and the Cutting tool installation manner hole, and wherein guide shaft is located in the guide shaft installing hole by rolling bearing.
The lower end of described swinging axle is fixedly mounted on the slide by holding screw, prevents that swinging axle and slide from relatively rotating.
Described rolling bearing adopts conical bearing.
Beneficial effect of the present invention:But the inside and outside groove of car pipe fitting has solved because tube wall thickness is inhomogeneous, and the problems such as groove is inhomogeneous, wall thickness deflection is larger appear in the processing rear tubular member that out-of-shape causes, and have improved groove crudy and the precision of pipe fitting.

The specific embodiment:
Shown in Fig. 1,2,3,4, the present invention includes slide 2 and knife rest swinging block 3, knife rest swinging block 3 vertically is 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 links together with swinging axle 4 by swinging axle installing hole and rolling bearing 5, consists of a swing mechanism.The centre that guide shaft 11 is installed in knife rest swinging block 3 by bearing is on the lower in the guide shaft installing hole of face; Groove cutter 17 is fixed in the Cutting tool installation manner hole of top of knife rest swinging block 3 centres by blade row trip bolt 16.Slide 2 is established the slide installing hole, and slide 2 is connected connection by bolt with slide block, and slide block 15 is installed on the slide rail 20 of cutterhead 19, consists of a slide mechanism, can make slide block mobile or fixing at the slide rail 20 of cutterhead 19 by the adjusting bolt degree of tightness.Knife rest swinging block 3 can rotate around swinging axle 4.The lower end of swinging axle 4 is installed on the slide 2, and fixes with holding screw, prevents that swinging axle 4 and slide 2 from relatively rotating.Rolling bearing adopts conical bearing, can prevent that pipe bevel from adding the axial force that produces man-hour.
Operation principle of the present invention: be processed as example with the outer groove of pipe fitting, cutterhead 19 rotations, slide 2 fixed thereon is along with rotation, the periphery of guide shaft 11 is adjacent to the inwall of processed pipe fitting 18 at this moment, if processed pipe fitting regular shape (being circular) at this moment knife rest swinging block 3 can not rotated around swinging axle 4, outer groove cutter 17 is apart from the invariant position at cutterhead center, and the pipe bevel after the processing is even.If processed pipe fitting out-of-shape (not being circular), at this time the inwall of processed pipe fitting 18 can produce an active force radially to guide shaft 11, thereby guide shaft 11 band movable knife rack swinging blocks 3 are rotated around swinging axle 4; This just make outer groove cutter 17 apart from the position at cutterhead center the change in radius along with processed pipe fitting, in cutterhead 19 rotary courses, the periphery of guide shaft 11 is pasting the inwall of processed pipe fitting 18 all the time; The Relative position determination of guide shaft 11 and outer groove cutter 17, outer groove cutter 17 are finished the outer groove processing to pipe fitting in the rotary course of slide 2.Therefore the inside and outside groove that carries out pipe fitting with this floating tool holder adds man-hour, can make the pipe bevel after the processing, and wall thickness is even, and error is little, and precision is high.
According to the diameter of pipe fitting to be processed, can whole floating tool holder be fixed on the correct position of cutterhead 19 by the slide block 15 of regulating the floating tool holder on the cutterhead 19 during use.
Above-mentioned only is embodiments of the invention, and to one skilled in the art, the present invention has multiple change and variation.Allly within invention thought of the present invention and principle, make any modification, be equal to replacement, improve etc., all should be included within protection scope of the present invention.
