Abstract
The utility model discloses a boring cutter, which belongs to the field of metal cutting tools. The traditional boring cutter cannot be automatically and finely tuned when the rough machining conversion is carried out so as to easily influence the processing precision. The boring cutter is mainly characterized by being provided with a fine tuning mechanism which comprises a fine tuning inner shaft, a fine tuning outer shaft and a fine tuning knob; one end of the fine tuning outer shaft is fixedly connected with a blade seat; a screw hole is arranged at the other end of the fine tuning outer shaft; the fine tuning inner shaft is provided with external threads; a transverse stepped through hole is arranged at the front end of a cutter bar; a plane end surface is arranged at one end hole part of the stepped through hole; circumferentially-distributed scales are formed on the end surface of the fine tuning knob and the plane end surface; the fine tuning outer shaft is arranged in the stepped through hole in a penetrating manner; one end of the fine tuning inner shaft is inserted into the screw hole of the fine tuning outer shaft to form threaded fit; the other end of the fine tuning inner shaft is arranged in a bearing support in the stepped through hole and is connected with the fine tuning knob; the cutter bar is provided with a screw hole which is communicated with the stepped through hole; and a locking screw is arranged in the screw hole and is abutted against the fine tuning outer shaft. The distance fine turning of a blade relative to the cutter bar can be realized by setting the fine tuning mechanism.
Description
Technical field
The utility model belongs to the metal cutting tool field, and is especially relevant with a kind of boring cutter.
Background technology
During the fine finishining of boring machine bore hole, need carry out tool setting on the roughing basis, general tool setting is to realize by follow rest.Such tool setting mode is easy to generate error, influences machining accuracy.
The utility model content
The purpose of this utility model is exactly will solve when using existing boring cutter to carry out roughing, fine finishining conversion self to finely tune the technical problem that influences machining accuracy easily, and a kind of boring cutter of realizing the relative knife bar distance fine regulation of blade is provided.For this reason, the utility model is by the following technical solutions:
A kind of boring cutter comprises knife bar, blade bearing and blade, it is characterized in that: described boring cutter also comprises micro-adjusting mechanism, micro-adjusting mechanism comprises axle in the fine setting, fine setting outer shaft and vernier knob, fine setting outer shaft one end is fixedlyed connected with blade bearing, and the other end is provided with screw, and axle is provided with external screw thread in the fine setting; Described knife bar front end is provided with the lateral step through hole, and step through-hole one stomidium mouth place is a planar end, and the scale of circumferential distribution is set on this planar end; The fine setting outer shaft is threaded onto described step through-hole, axle one end is plugged in the interior threaded engagement that forms of screw of fine setting outer shaft in the fine setting, the other end is by being arranged at the bearings in the step through-hole and being connected with vernier knob, the end face of vernier knob be provided with described planar end on the corresponding scale of scale; Described knife bar is provided with screw, and this screw communicates with described step through-hole, and lock-screw is set in the screw, and lock-screw is resisted against described fine setting outer shaft, and the fine setting outer shaft is played the locking positioning effect.
When the utility model used, knife bar was installed on the boring machine knife rest, in the time of need finely tuning boring cutter, unclamp lock-screw earlier, rotary fine adjustment knob, axle in the driven rotary fine setting, because axle is installed by bearings in the fine setting, circumferential position is fixed, and then finely tune outer shaft and can be in fine setting axially move under the drive of axle, thereby the blade position of drive on the blade bearing moves, after fine setting is finished, tighten lock-screw, will finely tune the outer shaft locking positioning, finish the whole trim process of boring cutter.
Use the utility model can reach following beneficial effect: the utility model can be realized the relative knife bar distance fine regulation of blade by micro-adjusting mechanism is set, when roughing and fine finishining conversion tool setting, needing to avoid follow rest, improve the tool setting precision, thereby can improve machining accuracy.
