Front views of the Fig. 1 for the embodiment of the present invention；
Left views of the Fig. 2 for the embodiment of the present invention；
Broaching tool operating diagrams of the Fig. 3 for the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As Figure 1-3, it is the preferred embodiments of the present invention.
Process hard tooth high speed internal broacher include base 1, lathe bed 2, drive mechanism 21, Griffe mechanism 22, balance weight mechanism 23,
Table 3, the first slide plate 4, main chuck mechanism 41, broaching tool 5, the second slide plate 6, auxiliary chuck mechanism 61, feed mechanism 31, protective cover
34.
Its medial bed 2 and table 3 are both secured on base 1, and table 3 is located at the front of lathe bed 2, and feed mechanism 31 is arranged on
In table 3, and feed mechanism 31 is provided with the workpiece tray 32 for placing workpiece, workpiece can quick and precisely be delivered to cutting position, be
Prevent workpiece from offseting in transport or the course of processing, workpiece locating piece 33 is additionally provided with workpiece tray 32.
Protective cover 34 is stood in table 3, is prevented chip of the workpiece during broaching from splashing, is hurt operator.
Drive mechanism 21 is arranged on 2 top of lathe bed, there is clutch end below drive mechanism 21, on 4 energy of the first slide plate
Being connected on lathe bed 2 and with the clutch end of drive mechanism 21 for lower movement, captures the main chuck mechanism 41 of 5 bottom of broaching tool
On the first slide plate 4.2 inner back side of lathe bed is provided with the balance weight mechanism 23 of the first slide plate of counterweight 4.
Griffe mechanism 22 is located at 2 positive front portion of lathe bed, and the second slide plate 6 is installed on 2 front portion of lathe bed and drives in Griffe mechanism 22
Lower energy moves up and down, and captures the auxiliary chuck mechanism 61 at the top of broaching tool 5 on the second slide plate 6, and the second slide plate 6 is slided positioned at first
In front of plate 4, main chuck mechanism 41 is located at below auxiliary chuck mechanism 61.
Common broaching tool is positive rake angle, the phenomenon that tipping or hypodontia often occur during broaching, and the broaching tool 5 of the present embodiment is
Negative rake, it is possible to decrease the generation of the phenomenon.
The course of work of the high speed internal broacher is as follows：
Original state：Workpiece is placed in the workpiece tray 32 on feed mechanism 31, and will using workpiece locating piece 33
