Description
Technical field
The utility model belongs to machine tool accessories field, and what relate to is a kind of slotting machine slotting tool, and what be specifically related to is a kind of resilient blade.
Background technology
Slotting machine is mainly used in the inner hole key slot processing in single-piece, small lot batch manufacture.Due to the particularity of shaping technique, when shaping length is shorter and arbor stiffness is stronger, utilize existing slotting tool to carry out shaping, the vibration cutting caused because of " knife " is more serious, and the inner hole key slot crudy making some required precisions higher is difficult to ensure.So, by improving existing slotting tool structure, necessary to improve shaping quality.
Summary of the invention
The purpose of this utility model is the deficiency overcoming the existence of existing slotting tool, proposes a kind of by changing slotting tool structure, the resilient blade of raising shaping quality.
The technical scheme realizing above-mentioned purpose is: a kind of resilient blade, comprise knife bar, sleeve pipe and cutter hub, it is characterized in that, described knife bar is a cross section is the straight-bar of rectangle, middle before knife bar bottom is provided with vertical channel, orthogonal manhole is provided with between left and right sides, manhole dead ahead is provided with the left and right side simultaneously penetrating knife bar, above and the level trough of manhole, below manhole and vertical channel bottom surface with after knife bar between be provided with the square through hole wide and orthogonal with vertical channel, tapped through hole is provided with between below square through hole bottom surface and knife bar.Described sleeve pipe be one isometric and have the elastic circular duct of a breach along its length with manhole, sleeve pipe is a tight fit in manhole.Described cutter hub is " Z " font, and cutter hub is located in vertical channel and square through hole.
The utility model structure is simple, convenient mounting and clamping, and adopt this resilient blade to add little, the long service life of vibration cutting in man-hour, the surface quality of workpieces of processing is good, machining accuracy is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2 and Fig. 4 ~ Fig. 6, a kind of resilient blade of the utility model, comprise knife bar 1, sleeve pipe 2 and cutter hub 3, it is characterized in that, described knife bar 1 is a cross section is the straight-bar of rectangle, middle before knife bar 1 bottom is provided with vertical channel 102, orthogonal manhole 101 is provided with between left and right sides, manhole 101 dead ahead is provided with the left and right side simultaneously penetrating knife bar 1, above and the level trough 103 of manhole 101, the square through hole 104 wide and orthogonal with vertical channel 102 is provided with at vertical channel 102 bottom surface and knife bar 1 below below manhole 101, square through hole 104 bottom surface and knife bar 1 are provided with tapped through hole 105 below.Described sleeve pipe 2 be one isometric and have the elastic circular duct of a breach along its length with manhole 101, sleeve pipe 2 is a tight fit in manhole 101.Described cutter hub 3 is " Z " font, and cutter hub 3 is located in vertical channel 102 and square through hole 104, and is fixed by screw rod 4.
As shown in Figure 3, when adopting existing plunge tooling, because shaping cutter easily vibrates, existing slotting tool knife bar 5 rigidity is comparatively strong in addition, cannot absorbing vibrational energy, so " knife " phenomenon is more serious.Meanwhile, because existing slotting tool cutter hub 6 and existing slotting tool knife bar 5 be linear contact lay at M place, under the effect of vibratory impulse, this place very easily occurs to wear and tear or be out of shape, and this not only makes reduce cutter life, and " knife " phenomenon also can be made even more serious.
As shown in Figure 1, this resilient blade is adopted to add man-hour, " Z " font cutter hub 3 vertical component be below that face contacts with vertical channel 102 bottom surface, the upwards active force of workpiece to cutter hub 3 point of a knife passes to knife bar 1 by its contact surface, there will not be the wearing and tearing as M point in Fig. 3 or distortion.Simultaneously, when vibrating in cutter hub 3 process, the bottom of knife bar 1 vibrates thereupon, because knife bar 1 is provided with level trough 103 and spring-backed quill 2, knife bar 1 bottom vibration deformation energy will be absorbed by spring-backed quill 2, thus reach the object absorbing impulsive force, buffering vibration, make knife bar 1 entirety there will not be larger vibration, ensure that piece surface matter processing capacity, improve processing precision of products.
