Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of modified boring bar.
Background technology
In the production process of reality; often can run into the processing problems of high accurate hole; this just needs high-accuracy boring machine to ensure, and by improving, optimizing and improve some structure of fine boring machine, effectively can improve and ensure the precision index required by hole machined.In machining, boring cutter is usually used to carry out hole machined.General boring cutter is made up of handle of a knife, boring bar and cutter.In machine operation process, boring bar can produce vibration, this vibration can cause the surface quality of machining hole unstable, the surface roughness being mainly manifested in machining hole is excessive, once amplitude is bigger than normal, and workman does not discover in time, can cause and add hole product rejection out, therefore be necessary to make monitoring to the amplitude of boring bar, so that early warning in time.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of modified boring bar.
The utility model is achieved through the following technical solutions:
A kind of modified boring bar, comprise boring bar body, body of rod connecting portion and cutter connecting portion, described boring bar body is provided with groove, and groove is built-in with vibration monitoring device, and described body of rod connecting portion is provided with connection tongue-and-groove.
As preferably, described body of rod connecting portion is together with being bolted between boring bar.
As preferably, described cutter connecting portion is provided with boring cutter installing hole and boring cutter fixing hole.
As preferably, described boring cutter installing hole is vertical with boring cutter fixing hole.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by installing vibration monitoring device, can reflect the Vibration Condition of boring bar in time, and make early warning; Being inserted by joint tongue connects in tongue-and-groove, improves the connection effect of boring bar, alleviates vibration further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
