Abstract
The utility model relates to a boring mill cutter bar, including the pole body, fix the knife rest in pole body one end, be provided with an at least tool setting groove on the knife rest, every tool setting groove is about the axle center symmetry of pole body. Boring mill cutter bar during operation, the sword inslot of two symmetries be about two cutters of pole body axle center symmetry installation, has solved the problem of thick boring machining inefficiency.
Description
Technical field
The utility model relates to the part field of boring machine, particularly a kind of cutter bar of boring lathe.
Background technology
The knife bar carried of usual boring machine is standard component, be arranged in spindle hole, but need when installing tailstock is installed, dismounting is complicated, during particularly boring porous, dismounting is more complicated, and when crossing feed, need " beaing method " to complete, knife bar is arranged on the problem that boring machine facing head can solve dismounting complexity, but no matter be knife bar is arranged in spindle hole be also mounted on facing head, the cutter bite that heavy boring adds man-hour is all smaller, heavy boring working (machining) efficiency is low, and the bite increasing cutter then knife bar easily produces vibrations and causes processing to carry out.
Utility model content
The purpose of this utility model is to provide a kind of cutter bar of boring lathe, to solve the problem that in prior art, heavy boring working (machining) efficiency is low.
The technical solution of the utility model is: a kind of cutter bar of boring lathe, comprises shaft, is fixed on the knife rest of shaft one end, described knife rest is provided with at least one tool setting groove, and the axle center of every tool setting groove all about shaft is symmetrical.
Described cutter bar of boring lathe also comprises for the base that be connected removable with boring machine facing head, and base is fixedly connected with the other end of shaft.
Described base is provided with fixing hole, and the stationary plane that base is used for contacting with facing head is greater than the cross section of shaft.
Described shaft is for lengthening shaft.
Described shaft is hollow circular-tube structure.
The beneficial effects of the utility model are: described cutter bar of boring lathe, comprise shaft, be fixed on the knife rest of shaft one end, knife rest is provided with at least one tool setting groove, every tool setting groove is symmetrical about the axle center of shaft, during work, about shaft axle center symmetry, two cutters are installed in often pair of symmetrical cutter groove, add man-hour often less for the bite of cutter, cutter not easily produces vibrations, the bite superposition of often pair of cutter is equivalent to former one the twice of cutter bite, heavy boring working (machining) efficiency is substantially increased time less for cutter bite single, during often pair of tool sharpening, the radial forces of shaft is cancelled out each other and make shaft only by moment of torsion, knife bar is made to be not easy to produce vibrations.
Further, described shaft, for lengthening shaft, makes knife bar can process the hole of darker size.
Further, described shaft is hollow circular-tube structure, and the weight both having alleviated shaft in turn ensure that the intensity of shaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of cutter bar of boring lathe of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
The specific embodiment of cutter bar of boring lathe of the present utility model, as shown in Figure 1, described cutter bar of boring lathe comprises base 1, shaft 2, knife rest 3.Base 1 and boring machine facing head are bolted to connection, and the stationary plane that base 1 and boring machine facing head are fixed is greater than the cross section of shaft 2, can improve the stability of shaft 2 by increasing base 1 and the contact area of facing head.Shaft 2, for lengthening shaft, makes knife bar can process the hole of darker size; Shaft 2 is hollow circular-tube structure, and the weight both having alleviated shaft 2 in turn ensure that the intensity of shaft 2.One end of shaft 2 is fixed on base 1, and the other end is fixedly connected with knife rest 3, knife rest 3 is provided with two cutter grooves 31 about the axle center symmetry of shaft 2.During the work of cutter bar of boring lathe heavy boring, knife bar rotates, two cutters about shaft 2 axle center symmetry are installed in two cutter grooves, the axle center of acting surface also about shaft of two cutters and part to be processed is symmetrical, add man-hour often less for cutter bite, knife bar not easily produces vibrations, a pair cutter is processed simultaneously, its bite and be equivalent to single the twice of cutter bite, improve heavy boring working (machining) efficiency greatly, two cutters are operationally cancelled out each other to the radial forces of shaft, and shaft 2 is only subject to moment of torsion, and whole knife bar is not easily shaken.The utility model solves the low problem of heavy boring working (machining) efficiency.
In other embodiments of the present utility model, be also connected by screw between described base with boring machine facing head; Described shaft can also be hollow ellipsoid, rectangular structure; Described base also can not be established, and shaft is directly fixed on boring machine facing head; It is at least two right that described cutter groove can also be arranged.
Claims (5)
