Abstract
A precise boring cutter for a boring machine is provided, which comprises a cutter body and a cutter arbor. One end of the cutter body is provided with a screw blind hole inside which is provided with a micro-adjustment screw-lock insert. The inner and outer sides of the micro-adjustment screw-lock insert are provided with screws respectively. The outer side screw matches with the screw blind hole. The cutter arbor is provided with a screw and the cutter arbor is positioned inside the micro-adjustment screw-lock insert. The inner side screw of the micro-adjustment screw-lock insert matches with the screw on the cutter arbor. The screw distance of outer side screw of the micro-adjustment screw-lock insert is larger than that of inner side screw. One end of the cutter body is provided with an anti-rotation pin which is treading into the rail end surface of the cutter arbor. When in use, it only needs to rotate the micro-adjustment screw-lock insert, and the cutter arbor will go forward or retreat according to rotating angle of the micro-adjustment screw-lock insert. The utility model practices precise adjustment on the boring cutter via the rotation of the micro-adjustment screw-lock insert by making use of the discrepancy between the inner side and outer side screw distances of the micro-adjustment screw-lock insert so as to solve the hard problem of making micro-adjustment on boring cutter in precise processing and improve the production efficiency and processing precision and reduces cost as well.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to metal-cutting machine tool, particularly boring machine instrument, and concrete is a kind of boring machine fine setting fine boring cutter.
Background technology:
In the prior art, in the boring process, need often cutter to be adjusted, but in the right boring process, adjustment amount is often very little, reach very difficulty of desirable adjustment position, adopt special-purpose tool setting gauge to finely tune at present, still, special-purpose tool setting gauge uses inconvenient, make complexity, the cost height is unfavorable for raising the efficiency in the right boring process.
Summary of the invention:
The purpose of this utility model provides a kind of boring machine fine setting fine boring cutter, and described this boring machine fine setting fine boring cutter will solve prior art and be difficult to technical problem that cutter is accurately adjusted in the process when right boring.
This boring machine fine setting fine boring cutter of the present utility model is made of cutter hub and knife bar, the front end of described knife bar is provided with blade, wherein, be provided with tapped blind hole in one end of described cutter hub, be provided with a fine setting swivel nut in the described tapped blind hole, the inboard and the outside of described fine setting swivel nut are respectively arranged with screw thread, the outside screw of fine setting swivel nut cooperates with tapped blind hole, knife bar is provided with screw thread, knife bar is arranged in the fine setting swivel nut, the inside thread of fine setting swivel nut and the threaded engagement on the knife bar, the pitch of fine setting swivel nut outside screw is greater than the pitch of fine setting swivel nut inside thread, one end of cutter hub is provided with a stop pin, and described stop pin penetrates in the breech face of knife bar.
Further, the central axis spaced and parallel of the central axis of described stop pin and knife bar.
Further, described fine setting swivel nut outside screw is M36 * 1.75 specifications, and described fine setting swivel nut inside thread is M24 * 1.5 specifications.
Operation principle of the present utility model is: because the pitch of fine setting swivel nut outside screw is greater than the pitch of fine setting swivel nut inside thread, the specification of outside screw is M36 * 1.75, the specification of inside thread is M24 * 1.5, rotate the fine setting swivel nut during use, knife bar just advances according to the rotational angle of finely tuning swivel nut or retreats.At this moment, the inside and outside pitch of fine setting swivel nut differs 0.25 millimeter, so the moving circle of fine setting swivel nut revolution, lathe tool just can advance or retreat 0.25 millimeter.Determine adjustment amount according to measurement result during use, determine the rotational angle of fine setting screw rod then.Such as: determine that by measuring the back boring cutter needs 0.125 millimeter of feeding, fine setting swivel nut rotational angle=360 * 0.125/0.25=180 degree is promptly finely tuned swivel nut and is rotated 180 degree, but just 0.125 millimeter of feeding of boring cutter.
The utility model and prior art contrast, and its effect is actively with tangible.The poor of the swivel nut outside and inboard pitch finely tuned in the utility model utilization, by the rotation of fine setting swivel nut accurate adjustment carried out in the feeding of boring cutter, solved the difficult problem that the boring cutter trace is adjusted in the fine finishining, improved production efficiency and machining accuracy, reduces cost simultaneously.
Description of drawings:
Fig. 1 is the cross-sectional view of boring machine fine setting fine boring cutter of the present utility model.
The specific embodiment:
As shown in Figure 1, boring machine fine setting fine boring cutter of the present utility model is made of cutter hub 1 and knife bar 2, the front end of described knife bar 2 is provided with blade 3, wherein, be provided with tapped blind hole in one end of described cutter hub 1, be provided with a fine setting swivel nut 4 in the described tapped blind hole, the inboard and the outside of described fine setting swivel nut 4 are respectively arranged with screw thread, the outside screw of fine setting swivel nut 4 cooperates with tapped blind hole, knife bar 2 is provided with screw thread, knife bar 2 is arranged in the fine setting swivel nut 4, the inside thread of fine setting swivel nut 4 and the threaded engagement on the knife bar 2, the pitch of fine setting swivel nut 4 outside screw is greater than the pitch of fine setting swivel nut 4 inside threads, and an end of cutter hub 1 is provided with a stop pin 5, and described stop pin 5 penetrates in the breech face of knife bar 2.
Further, the central axis spaced and parallel of the central axis of described stop pin 5 and knife bar 2.
Further, described fine setting swivel nut 4 outside screw are M36 * 1.75 specifications, and described fine setting swivel nut 4 inside threads are M24 * 1.5 specifications.
