Specific embodiment
In order that the present invention can be more clearly and readily understood, it is right below according to specific embodiment and with reference to attached drawing
The present invention is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of cam orientation key, including last time swivel 7, cam, block
3rd, pressing plate 5, hollow positioning key 2 and lower revolving body 8, the block 3 are fixedly connected on by screw 4 on last time swivel 7, pressing plate
5 are fixedly connected on by screw 6 on last time swivel 7, and cam has the camshaft 1 of eccentric setting, and one end of camshaft 1, which is fixed, to be connected
It is connected on last time swivel 7, the other end is fixedly connected on pressing plate 5, and the hollow positioning key 2 is sleeved on outside cam, block 3, pressure
Plate 5 and last time swivel 7 surround the sliding space that hollow positioning key 2 is made to slide up and down wherein jointly, when camshaft 1 rotates
When, hollow positioning key 2 moves up and down in sliding space；The upper end of the lower revolving body 8 is provided with and 2 phase of hollow positioning key
The locating slot of cooperation, after revolving body 8 turns round in place instantly, hollow positioning key 2 with camshaft 1 rotation slide downward and insert
Enter in locating slot.
