Abstract
The utility model relates to a lengthened cutter bar used for fixing a cutter handle, and belongs to the machining industry. The lengthened cutter bar comprises a cutter bar body, wherein a thickened section is formed at the lower end of the cutter bar body, the diameter of the thickened section is larger than that of the cutter bar body, the thickened section and the cutter bar body are in transition through a cone, a cutter handle is fixed to the lower end of the thickened section, and the cutter handle is fixed through screws arranged on the lower end face of the thickened section. The lengthened cutter bar can machine small inner holes and slope planes, effectively reduce vibration of a common cutter bar, and guarantee roughness and size accuracy of a machining surface.
Description
Technical field
The utility model relates to a kind of lengthened tool arbor for fixing handle of a knife, belongs to mechanical processing industry.
Background technology
In mechanical processing industry, lengthened tool arbor is to use very wide a kind of knife bar, in the dark endoporus of processing or when the plane vertical with hole at box house, generally to make a straight knife bar, the diameter in knife bar diameter and hole has direct relation, and in the time that bore dia is very little, in process, knife bar can produce vibrations, thereby affect machined surface roughness, can affect dimensional accuracy simultaneously.
Summary of the invention
The utility model has solved the existing problem of prior art, provides one can process the less and gradient plane of endoporus, can effectively reduce knife bar vibrations, has ensured the lengthened tool arbor of roughness and the dimensional accuracy of finished surface.
Above-mentioned technical purpose of the present utility model solves by the following technical programs: it comprises knife bar body, the lower end of described knife bar body is formed with overstriking section, the diameter of described overstriking section is greater than the diameter of knife bar body, between overstriking section and knife bar body, pass through cone transition, the lower end of overstriking section is fixed with handle of a knife, and described handle of a knife is fixed by the screw that is arranged on overstriking section lower surface.Wherein, form overstriking section can reduce the flexible of knife bar in the lower end of knife bar body, improve the stability of knife bar in process, the increasing that reduces knife bar is moving, and then has ensured roughness and the dimensional accuracy of finished surface.Due under normal circumstances, the how cross-shaped state of axis in knife bar axis and processed hole, therefore by cone transition, can avoid producing and interfering between knife bar and processed hole hole wall between knife bar body and overstriking section, also be convenient to overstriking section to be inserted in processed hole simultaneously.
As preferably, described overstriking section lower end side is also provided with the trip bolt of reinforcing handle of a knife, thus effective locking knife handle, must process in handle of a knife shake, ensured roughness and the dimensional accuracy of finished surface.
As preferably, described overstriking section lower end side is formed with breach, thereby can avoid the interference between knife bar and processed hole wall.
Therefore, the utlity model has and can process the less and gradient plane of endoporus, can effectively reduce knife bar vibrations, ensured the feature such as roughness and dimensional accuracy of finished surface.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1, the lower end of knife bar body 1 is formed with overstriking section 2, the diameter of overstriking section 2 is greater than the diameter of knife bar body 1, between overstriking section 2 and knife bar body 1, pass through cone 3 transition, the lower end of overstriking section 3 is fixed with handle of a knife 4, and handle of a knife 4 is fixed by the screw 5 that is arranged on overstriking section 2 lower surfaces.Wherein, form overstriking section 2 can reduce the flexible of knife bar in the lower end of knife bar body 1, improve the stability of knife bar in process, the increasing that reduces knife bar is moving, and then has ensured roughness and the dimensional accuracy of finished surface.As shown in Figure 1, due under normal circumstances, the how cross-shaped state of axis in knife bar axis and processed hole 8, therefore between knife bar body and overstriking section by cone transition, can avoid producing and interfering between knife bar and processed hole 8 hole walls, be also convenient to overstriking section to be inserted in processed hole simultaneously.Overstriking section 2 lower end side are also provided with reinforces the trip bolt 6 of handle of a knife, thus effective locking knife handle 4, must process in handle of a knife shake, ensured roughness and the dimensional accuracy of finished surface.Overstriking section 2 lower end side are formed with breach 7, thereby can avoid the interference between knife bar and processed hole hole wall.
Claims (3)
1. a lengthened tool arbor, comprise knife bar body, the lower end that it is characterized in that described knife bar body is formed with overstriking section, the diameter of described overstriking section is greater than the diameter of knife bar body, between overstriking section and knife bar body, pass through cone transition, the lower end of overstriking section is fixed with handle of a knife, and described handle of a knife is fixed by the screw that is arranged on overstriking section lower surface.
