Abstract
The utility model discloses a radially adjustable boring bar for finish-machining large holes of large equipment. The boring bar comprises a boring bar body and an adjusting boring bar, wherein one end of the boring bar body is provided with a tapered mounting handle used for being inserted into a main shaft of a boring lathe. The adjusting boring bar is inserted into the boring bar body vertically and fixed on the boring bar body through a first compression screw; and a square groove which is used for installing a cutter is formed in the adjusting boring bar. The radially adjustable boring bar for finish-machining large holes of large equipment can meet the requirement of boring large aperture workpieces and end faces by using a single shaft on an ordinary boring lathe; the gravity cutting strength and accuracy are enhanced through improvement, the effect is improved by more than 3 times, the requirement of heavy load can be met, clamping is achieved conveniently and flexibly, and different cutters can be mounted on a cutter holder, so that different products can be manufactured.
Description
Technical field
The utility model relates to field of machining, but is specifically related to a kind of main equipment macropore fine finishining radiai adjustment boring bar.
Background technology
At present, boring machine is field of machining equipment commonly used, and boring bar is the important composition parts of boring machine, is even directly determining the processing characteristics of boring machine and the size of the range of work.At present, the boring bar of the common boring machine that small-sized machine processing factory uses, can only carry out boring processing to small diameter bore, and main equipment large diameter hole base part is added man-hour, common boring bar is faced with the problems such as strenuous vibration and the thinner insufficient strength of boring bar, can not be with the wide-aperture workpiece of single shaft boring and end face on common boring machine.
Summary of the invention
But the technical problem that the utility model solves is to provide a kind of main equipment macropore fine finishining radiai adjustment boring bar, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
But a kind of main equipment macropore fine finishining radiai adjustment boring bar, comprise the boring bar body, one end of described boring bar body has to insert the taper installing handle of boring spindle, also comprise the adjusting boring bar, described adjusting boring bar is vertical to be inserted in described boring bar body, and utilize the first housing screw to be fixed on described boring bar body, described adjusting boring bar is provided with the square groove for mounting cutter.
As a kind of improvement, described cutter utilizes the second housing screw to be anchored in described square groove.
Under this structure, the main shaft rotation is done to seesaw and can be processed endoporus or end face.And that regulates that the position of boring bar can be along described boring bar body radially carries out position adjustments.
The scope of the utility model processing endoporus is Φ 200-400mm.
Owing to having adopted above structure, the utlity model has following beneficial effect:
The utility model can satisfy the requirement of using the wide-aperture workpiece of single shaft boring and end face on common boring machine, by having strengthened gravity cutting hardness, precision after improving, improve effect more than 3 times, can satisfy heavy duty requirement, convenient mounting and clamping is flexible, can different tool sharpening different products be installed at cutter holder.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, but a kind of main equipment macropore fine finishining radiai adjustment boring bar, comprise boring bar body 1, one end of described boring bar body 1 has to insert the taper installing handle 2 of boring spindle, also comprise and regulate boring bar 3, the vertical insertion in described boring bar body 1 of described adjusting boring bar 3, and utilize the first housing screw 4 to be fixed on described boring bar body 1, described adjusting boring bar 3 is provided with the square groove 7 for mounting cutter.
As a kind of improvement, described cutter 5 utilizes the second housing screw 6 to be anchored in described square groove 7.
Under this structure, the main shaft rotation is done to seesaw and can be processed endoporus or end face.And that regulates that the position of boring bar 3 can be along described boring bar body 1 radially carries out position adjustments.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
