Abstract
The utility model discloses a novel cutter bar, and relates to a lathe accessory device. An existing cutter bar has the defects of being not stable when assembled and combined with a main shaft, and short in service life. The novel cutter bar comprises a cutter bar body and a flange. The cutter bar body is composed of a taper part and a column-shaped part which is equal to a bottom circle of the taper part in diameter. The upper end face of the flange is a plane. The flange is provided with an axial central hole and at least one radial limiting hole and is sleeved on the column-shaped part through the central hole. The upper end face of the flange is not higher than the bottom face of the taper part. The column-shaped part is provided with a radial limiting hole corresponding to the radial hole on the flange. A limiting screw is screwed in the radial limiting hole of the flange and the radial limiting hole of the column-shaped part to fix the flange in the circumferential and axial direction in a limiting mode. According to the novel cutter bar, the flange is arranged to improve axial limiting of the cutter bar, stability between the cutter bar and the main shaft is improved, vibration is reduced at machining time, and machining precision is improved.
Description
Technical field
The utility model relates to a kind of lathe auxiliary equipment, and is especially relevant with a kind of Novel knife bar.
Background technology
The tradition knife bar has tapered portion and the cylindrical portion that links into an integrated entity, the cylindrical portion diameter is identical with circular diameter at the bottom of the tapered portion, tapered portion is used for cooperating installation with the taper hole of spindle nose, cylindrical portion is used for the clamping cutter, the tapered portion end face is installed blind rivet and is cooperated with the broaching tool pawl of mainshaft mechanism knife bar is carried out axial limiting, main shaft bellmouth inwall and knife bar tapered portion outer surface are fitted to each other and have unavoidably the slit, in process, because main shaft High Rotation Speed, knife bar is just stable not with cooperating of main shaft, knife bar easily produces vibrations, and knife bar tapered portion outer surface and main shaft bellmouth inwall easily produce wearing and tearing, has affected the life-span of knife bar.
The utility model content
The purpose of this utility model be intended to solve traditional knife bar exists be combined with spindle mounted stable not, easily produce the defective of wearing and tearing, provide a kind of can with the Novel knife bar of main shaft secure fit.
For this reason, the utility model is by the following technical solutions: a kind of Novel knife bar, comprise the knife bar body, the knife bar body is comprised of tapered portion and cylindrical portion, the end circular diameter of the diameter of cylindrical portion and tapered portion equates, it is characterized in that, described knife bar also comprises flange, the flange upper surface is the plane, flange is provided with radially spacing hole of axial center hole and at least one, flange is sleeved on the cylindrical portion by centre bore, the flange upper surface is not higher than the tapered portion bottom surface, be provided with the radially spacing hole corresponding with radially spacing hole on the flange on the described cylindrical portion, be screwed stop screw in the radially spacing hole of flange and the radially spacing hole of cylindrical portion, flange is carried out circumferential and axial spacing fixing.
When the utility model uses, the end face of knife bar tapered portion is equipped with blind rivet, and tapered portion is inserted the main shaft bellmouth, and flange upper surface and main shaft end face are fitted, by flange upper surface and mainshaft mechanism broaching tool pawl knife bar is carried out axial restraint, improved the installation firmness of knife bar on main shaft.
Use the utility model can reach following beneficial effect: the utility model increases the axial limiting of knife bar by mounting flange, improved the stable degree between knife bar and the main shaft, adds to reduce man-hour to produce vibrations, has improved the processing precise degree.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As described in Figure 1, the utility model comprises knife bar body and flange 2, the knife bar body is comprised of tapered portion 1 and cylindrical portion 4, the end circular diameter of the diameter of cylindrical portion 4 and tapered portion 1 equates, the flange upper surface is the plane, flange 2 is provided with radially spacing hole of axial center hole and 4, flange 2 is sleeved on the cylindrical portion 4 by centre bore, the flange upper surface is not higher than the tapered portion bottom surface, be provided with the radially spacing hole corresponding with radially spacing hole on the flange 2 on the described cylindrical portion 4, be screwed stop screw 3 in the radially spacing hole of flange 2 and the radially spacing hole of cylindrical portion 4, flange 2 carried out circumferential and axial spacing fixing.
When the utility model uses, the end face of knife bar tapered portion 1 is equipped with blind rivet, and tapered portion 1 is inserted the main shaft bellmouth, and the upper surface of flange 2 and main shaft end face are fitted, upper surface and mainshaft mechanism broaching tool pawl by flange 2 carry out axial restraint to knife bar, have improved the installation firmness of knife bar on main shaft.
