The supporting plate that vertical lifting can be driven by lifting motor is provided between the drilling seat and workbench, when supporting plate is held
Support may carry drilling seat vertical lifting at the bottom of drilling seat.
The lifting motor drives supporting plate lifting by screw body.
The weight body includes box body and is placed in the intracorporal clump weight of box.
The utility model has the advantages that:
1, the method and device of the utility model uses forced feed during test drilling.It can simulate so hand-held
The operating condition of electric drill keeps product test scene close with real use state, detection data is enable more accurately to react it
Cutting ability and index of aging；Simultaneously because feed pressure is constant, the fixed amount of feeding test of tradition is avoided in drill bit failure
It is damaged caused by equipment；
2, it is accurately positioned using lifting process of the locating and detecting device to drilling seat, to different phase using different
Lifting speed both improves test efficiency, can also anti-forced feed contact workpiece and close to drill through when " touching knife " and " cultivation
Knife " phenomenon reduces the abnormal damage of drill bit and equipment.
3, it can be realized by controller and automatically record drilling hole sequence and corresponding aperture drilling time, and relevant documentation can be formed
And chart, it facilitates and drill bit performance data is analyzed.

Fig. 1 is the drill bit automatic testing machine structural schematic diagram of the utility model embodiment.
Fig. 2 is the control system schematic diagram of the utility model embodiment.
Fig. 3 is the test method step schematic diagram of the utility model embodiment.
Specific embodiment
As shown in Figure 1, the rack of the drill bit automatic testing machine of the utility model includes column 1 and workbench 2, on column 1
It is provided with vertical guide rail, is equipped with to be equipped on the drilling seat 3 of guide rail vertical lifting, drilling seat on guide rail and be driven by power
The drill chuck 4 of dynamic rotation；Drilling seat 3 is connected with the pressure that can apply constant pressure to the drill bit Z-direction lower feeding on drilling seat
Mechanism 5；Workbench 2 is located at 3 lower section of drilling seat, and the examination base fixture 6 for positioning and clamping plate examination base P is equipped on workbench,
Examination base fixture 6 drives it to move horizontally by examination base driving motor 7；It is also equipped in rack and is able to detect 3 height and position of drilling seat
Locating and detecting device 8；The detection signal of locating and detecting device 8 is connected to a controller 9(and sees Fig. 2) detection signal input
End, the control instruction output end of controller are connected to the level that examination base fixture is controlled in the driving circuit of examination base driving motor 7
It is mobile.Examination base driving motor 7 includes the vertical shift motor and traversing motor that examination base fixture vertical and horizontal can be driven mobile.Pressure
