It further illustrating, fastening screw 42 passes through being fastenedly connected with main shaft 1 by being threadedly engaged for locking end cap 41,
During fastening screw 42 is connect with main shaft 1, locking end cap 41 can pressed against and squeezed along the axial direction of main shaft 1, grinding wheel is made
Together with the fitting of chuck 31 and main shaft 1 tightly.
It further explains, when emergency braking occurs for main shaft 1, clamping mechanism 3 can be held with abrasive disc 2 due to inertia
Continuous rotation, and fastening screw 42 can then stop rotating with main shaft 1, and locking end cap 41 is then in fastening screw 42 and grinding wheel chuck
Opposite sliding occurs between 31, in this way, being exactly to separate between fastening screw 42 and grinding wheel chuck 31, fastening screw would not be made
42 fall off with the rotation of abrasive disc 2.
As shown in figure 3, as a preferred embodiment, be provided with annular groove 321 on the grinding wheel end cap 32, it should
Annular groove 321 is arranged concentrically with the grinding wheel end cap 32, and the cross section of the annular groove 321 is trapezoidal setting.
As shown in Fig. 6, Fig. 7 and Fig. 8, further, at least one set of balancing unit is provided in the annular groove 321
322, which includes:
Outer balance weight 3221, the outer balance weight 3221 is close to setting with the outer wall of the annular groove 321, towards master
The side wall of axis 1 is provided with the first semi-circular threaded 3222；
Inner equilibrium block 3223, the inner equilibrium block 3223 are close to setting with the inner wall of the annular groove 321, backwards to main
The side wall of axis 1 is provided with the second semi-circular threaded 3224, second semi-circular threaded 3224 and first semicircular
The combination of pit 3222 forms complete threaded hole；And
Screw assemblies 3225, the screw assemblies 3225 and second semi-circular threaded 3224, first semicircle
The combination of shape threaded hole 3222 forms complete threaded hole and is threadedly engaged connection.
It should be noted that the weight at each position of abrasive disc 2 will appear unbalanced during installing abrasive disc 2
Situation carries out counterweight processing by increasing balancing unit 322, guarantees the balance of 2 each section quality of abrasive disc, guarantees main shaft 1
The stability of rotation extends the service life of main shaft 1.
The course of work:
In the braking of 1 emergency stop of main shaft, abrasive disc 2 connects the clamping of main shaft 1 Yu abrasive disc 2 since inertia continues to rotate
Also due to relative rotation occurs between the influence and main shaft 1 of abrasive disc 2, traditional fastening screw 42 is and clamping machine for mechanism 3
What the grinding wheel chuck 31 in structure 3 was wholely set, thus just will appear main shaft 1 stopping, grinding wheel chuck 31 rotate, fastening screw 42 with
The case where rotating, falling off together, and the utility model then grinding wheel chuck 31 is separated with locking end cap 41, by anti-
The transition of loose end cap 41 stops fastening screw 42 with main shaft is synchronous, and the then opposite sliding with grinding wheel chuck 31 of locking end cap 41.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
