Abstract
The utility model discloses a removable formula boring machine cutter, anterior including boring bar afterbody and boring bar, the front end of boring bar afterbody is equipped with the jack, and the anterior rear end of boring bar is equipped with inserts the axle, inserts during the axle inserts the jack, insert spool and the jack between be equipped with the key and the keyway of mutually supporting. The lateral part of inserting the axle is equipped with the screw hole, and the lateral wall of jack is equipped with the through -hole, and the bolt passes the through -hole and is connected to in the screw hole. The boring bar is dismantled more in a flexible way and need not to change the boring bar main part and makes it break away from the boring machine, and accessible change boring bar is anterior to make it increase the maximum machining depth and adapt to the processing of different apertures.
Description
Technical field
The utility model relates to a kind of boring machine cutter, particularly relates to a kind of changeable type boring machine cutter.
Background technology
At present, many hydraulic support producers all making great efforts replacement frequency when reducing the work of boring machine boring bar, improve the machining accuracy of bore hole, and the principal element affecting boring bar replacement frequency and Boring precision have following some:
1, boring bar length needed for machining hole; 2, tip radius needed for machining hole; 3, cutter adjustment during right boring.
As shown in Figure 1, used during boring machine bore hole of the prior art is integral type boring bar.Bore hole limit is maximum can working depth, need change boring bar and tool setting repeatedly frequently, had a strong impact on production efficiency and product quality when processing same workpiece.
Utility model content
The purpose of this utility model is to provide simple, the economic and practical changeable type boring machine cutter of a kind of structure.
The purpose of this utility model is achieved through the following technical solutions:
Changeable type boring machine cutter of the present utility model, comprises boring bar afterbody and boring bar is anterior, and described boring bar afterbody and boring bar front portion are interconnected;
The front end of described boring bar afterbody is provided with jack, and the rear end of described boring bar front portion is provided with slotting axle, and described slotting axle is inserted in described jack, is provided with the key and keyway that cooperatively interact between described slotting axle and described jack;
The sidepiece of described slotting axle is provided with screwed hole, and the sidewall of described jack is provided with through hole, and bolt is connected in described screwed hole through described through hole.
The technical scheme provided as can be seen from above-mentioned the utility model, the changeable type boring machine cutter that the utility model embodiment provides, owing to comprising boring bar afterbody and boring bar front portion, boring bar afterbody and boring bar front portion are interconnected, boring bar is made to dismantle more flexibly and make it depart from boring machine without the need to changing boring bar main body, make it increase maximum machining depth by changing boring bar front portion and adapt to different pore size processing, structure is simple, economic and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of boring machine cutter in prior art;
The structural representation of the changeable type boring machine cutter that Fig. 2 provides for the utility model embodiment one;
The structural representation of the changeable type boring machine cutter that Fig. 3 provides for the utility model embodiment two.
In figure:
1, boring bar is anterior, and 2, key, 3, bolt, 4, boring bar afterbody.
Detailed description of the invention
To be described in further detail the utility model embodiment below.
Changeable type boring machine cutter of the present utility model, its preferably detailed description of the invention be:
Comprise boring bar afterbody and boring bar front portion, described boring bar afterbody and boring bar front portion are interconnected.
The front end of described boring bar afterbody is provided with jack, and the rear end of described boring bar front portion is provided with slotting axle, and described slotting axle is inserted in described jack, is provided with the key and keyway that cooperatively interact between described slotting axle and described jack.
The sidepiece of described slotting axle is provided with screwed hole, and the sidewall of described jack is provided with through hole, and bolt is connected in described screwed hole through described through hole.
The rear end of described boring bar afterbody is connected with boring machine, and the front end of described boring bar front portion is fixed with boring cutter.
The utility model utilizes separate boring rod, makes boring bar dismantle more flexibly and make it depart from boring machine without the need to changing boring bar main body, makes it increase maximum machining depth by changing boring bar front portion and adapts to different pore size processing.In actual applications, some hole measurement difficulty are large, can utilize separate boring rod advantage, first to good forming-tool, after pull down boring bar front portion, then front portion is put into the boring bar afterbody of side, hole to be processed.During right boring, last cutter processing capacity can being reserved, pull down boring bar front portion afterwards, change standard fine finishining cutter head, the error that staff produces when adjusting cutter can being avoided.The method is able to checking through many experiments and large-tonnage product can guarantee machining hole precision, improves production efficiency simultaneously.
Specific embodiment:
As shown in Figure 2 and Figure 3, changeable type Design of Boring Bar is two parts, and boring bar front portion is used for fixed cutting tool, and boring bar afterbody is used for connecting with boring machine.
Boring bar front portion is designed with card key and keyway and screwed hole, to be anteriorly connected with afterbody for making, to fix and transmission.
Boring bar front portion can corresponding reduction diameter, for weight reduction, reduces because boring bar radial direction shakes the hole machined deviation produced.
The boring bar of this kind of structure, changes the frequency of boring bar, effectively ensure that the machining accuracy of bore hole requirement when reducing work.Conclusive effect is served to enhancing productivity.This structure is tried out in my company, by can save the expenditure that subsidiary factory uses for boring bar to the transformation of waste and old boring bar, and reduces the labour intensity of operator, improves the production efficiency in the unit interval.Originally put forward effect made major contribution for subsidiary factory falls.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
