Specific embodiment
Combined tap and drill drill bit chamfering grinding device, described device include the fixture 2, Yi Jiyong for clamping screw tap drill bit 1
In the grinding wheel 3 being ground to the screw tap drill bit 1；
1 lower part of screw tap drill bit is provided with the support device 4 being supported to the drill bit 1, the support device 4 have with
Lower function: detecting length travel fluctuation of the screw tap rotary head 1 in grinding process, and be provided with resetting apparatus make it is described
1 return of screw tap drill bit, to keep the stationarity in 1 grinding process of screw tap drill bit.
The support device 4 includes the support rod 41 being supported to the screw tap drill bit 1, and the support rod 41 includes solid
Surely the fixed link 411 that is arranged and the mobile bar 412 that can fix the up and down motion of bar 411 relatively is connected in fixed link 411, it is described
Mobile bar 412 and the screw tap drill bit 1 contact simultaneously form support to the screw tap drill bit 1；
The fixed link 411 and the hollow setting of mobile bar 412, inside forms the logical cavity for setting high pressure gas, in the support rod
41 side wall is formed with stomata 42, displacement sensor 43 is provided in the mobile bar 412, institute's displacement sensors 43 are for examining
The undulate quantity of 412 lengthwise position of mobile bar is surveyed, and is provided with control device and controls gas pressure in the cavity, passes through change
Gas pressure resets the screw tap drill bit 1.
It is provided with high-pressure gas storage vessels 5 and is connected to by the stomata 42 with cavity formation, and pass through control device control
Connection or cutting between high-pressure gas storage vessels 5 processed and the cavity.
The downside of the support rod 41 is arranged in the stomata 42, and the mobile bar 412 is internally provided with the relatively described shifting
The lantern ring 44 that lever 412 moves up and down, is provided with bullet between 44 upper surface of 412 top inner wall of mobile bar and the lantern ring
Spring 6.
Combined tap and drill drill bit chamfering grinding process, follows the steps below:
1) the screw tap drill bit 1 is clamped on the fixture 2, it is stand-by that grinding wheel 3 is then mounted on corresponding position；
2) the screw tap drill bit 1 is ground, in Grinding Process, when detect screw tap drill bit 1 occur up and down fluctuate
When, displacement sensor 43 detects the positional fluctuation amount of screw tap drill bit 1, then passes through the input in the cavity or output high pressure
Gas changes the pressure in cavity, so that the mobile bar 412 be driven to move up and down, then drives about the 1 screw tap drill bit
Movement, makes screw tap drill bit 1 carry out the processing of smooth sequential within certain fluctuation range；
3) during 2), the structure type of the lantern ring 44 also can be used, about 412 mobile bar is driven by lantern ring 44
Movement realizes the processing of 1 smooth sequential of screw tap drill bit so that the screw tap drill bit 1 be driven to move up and down.
The course of work of the invention are as follows: when displacement sensor 43 detects that the undulate quantity of the screw tap drill bit 1 is more than certain
When value, certain value herein is determined according to the machining accuracy of screw tap drill bit 1 and remaining requirement, and displacement sensing 43 will be examined at this time
The signal measured is sent to control device, and control device issues signal and passes through input or discharge high pressure gas in cavity, from
And change the size of gas pressure in cavity, drive mobile bar 412 to move up and down, when displacement sensor 43 detects the screw tap
When 1 return of drill bit, the pressure of empty intracavity gas stable at this time keeps 1 bearing up-down force of combined tap and drill drill bit balance, and so on real
Existing screw tap drill bit 1 guarantees the processing performance of screw tap drill bit 1 in the stability of longitudinal direction position, improves the processing of screw tap drill bit 1
Precision.
Further inside mobile bar 412 using the structure type of lantern ring 44, spring 6, purpose of design is the present invention
It is more steady in order to make mobile bar 412 move up and down, so that it is more steady to guarantee that screw tap drill bit 1 moves up and down, prevent because of certain
Factor causes the excessive bring correlation of gas pressure cataclysm bring mobile bar 412,1 motion amplitude of screw tap drill bit in cavity to lack
It falls into, further ensures the accuracy of the processing of screw tap drill bit 1.
In order to keep processing stability, the present invention processes in such a way that grinding wheel 3 is rotated around screw tap drill bit 1.
