Abstract
The utility model provides an extended boring cutter bar of a numerical control boring machine; the concrete mechanism is formed by assembling and welding a plate I, a rib plate and a plate II; wherein, the plate I is transversely arranged, and two ends of the bottom surface of the plate I are respectively and longitudinally provided with a plate II; and a rib plate is arranged at the connecting position of the plate I and the plate II, and two adjacent vertical edges of the rib plate are respectively fixed on the bottom surface of the plate I and the surface of the plate II. The utility model provides a structure, easy operation, it is not high to the requirement of digit control machine tool, and the process range is big, can satisfy not unidimensional requirement.
Description
Technical Field
The utility model particularly relates to an extension boring cutter pole of numerical control boring machine.
Background
The numerical control boring machine is mainly a machine tool for processing the existing prefabricated holes on a workpiece by using a boring cutter, wherein usually, the rotation of the boring cutter is a main motion, and the movement of the boring cutter or the workpiece is a feeding motion. It is mainly used for machining high-precision holes or finishing multiple holes by one-time positioning, and can also be used for machining other machining surfaces related to hole finishing. The use of different tools and accessories also allows drilling, milling, cutting with higher machining precision and surface quality than drilling machines. The boring machine is a main device for processing large box parts; thread, machining of excircle and end face and the like.
However, in the practical application process, many numerical control boring machines have the problems of insufficient cutter bar length and limited machining range in the practical machining process.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an extension boring cutter pole that machining range is big, the area is big, easy operation, security are high not enough to prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: providing a lengthened boring cutter bar of a numerical control boring machine; the concrete mechanism is formed by assembling and welding a plate I, a rib plate and a plate II; wherein, the plate I is transversely arranged, and two ends of the bottom surface of the plate I are respectively and longitudinally provided with a plate II; and a rib plate is arranged at the connecting position of the plate I and the plate II, and two adjacent vertical edges of the rib plate are respectively fixed on the bottom surface of the plate I and the surface of the plate II.
The plate I is of a rectangular structure, and four vertex angle positions of the plate I are all corner cutting structures; and a bolt hole and a key groove which are connected with a working spindle box of the numerical control boring machine are arranged in the middle of the plate I.
A groove for installing a boring cutter is formed in one end, far away from the plate I, of the plate II; and two bolt holes for fixing the boring cutters are arranged at one end of the groove for mounting the boring cutters on the plate II side by side in the direction vertical to the groove.
The rib plates are used for strengthening connection between the plates I and II, and rib plates are arranged on the front and back sides of the two plates II respectively.
The utility model has the advantages that: the operation is simple, the requirement on the numerical control machine tool is not high, the processing range is large, and the requirements of different sizes can be met; the security is high, simple to operate.
