The driving skill that the drive mechanism 7 of above-mentioned rotating disk 4 can be commonly used using motor of the prior art, reduction gearing etc.
Art, but preferential, adopt following structure in the present embodiment: this drive mechanism 7 includes the first of 41 installations coaxial with rotating disk
Ratchet 71a, the second ratchet 71b, the 3rd ratchet 71c and upright the transmission article can pump is fixed on fixed plate
72, as shown in figure 1, having for the jack 11 of above-mentioned transmission bar 72 insertion on workbench and being promoted and energy level by above-mentioned transmission bar
The movable block 73 of movement and compression spring 74a making reset after the movement of this movable block 73, the first ratchet is engaged with movable block
73 move horizontally the active ratchet 75a that it can be driven to rotate, and second and third ratchet is then engaged with after preventing rotating disk from rotateing in place respectively
The detent 75b being rotated further and after preventing rotating disk from rotateing in place reversion blocking pawl 75c, active ratchet, blocking pawl
Offset with the first spring 74b, second spring 74c, the 3rd spring 74d respectively with detent.In the present embodiment, in order to be able to make
Transmission bar 72 neatly promotes movable block 73, and the lower end of transmission bar is designed to wedge structure, relatively, and has on movable block 73
There is the inclined-plane 731 that matches with this transmission bar lower end.
In the present embodiment, the stationarity rotating in order to ensure axle and first, second, third ratchet and movable block are installed
Convenience, here, is additionally provided with five pieces of substrates below the workbench accommodating at rotating disk, is respectively first substrate from top to down
70a, second substrate 70b, the 3rd substrate 70c, tetrabasal 70d and the 5th substrate 70e, first substrate has with workbench on
The corresponding through hole 701a of jack；The axle 41 of rotating disk 4 is located in the axis hole of this five pieces of substrates successively, and first substrate
It is placed with bushing 76a in the axis hole of 70a, to prevent axle rocking in rotation process, and prevent the first substrate that weares and teares.Described
Above-mentioned first ratchet 71a is installed in the axis hole of two substrates and is set in spacing collar 77 outside this first ratchet, this second
The one pilot hole 701b being connected with the axis hole of second substrate is also had on substrate 70b, above-mentioned movable block 73 is seated in this and leads
Into the 701b of hole, and this movable block 73 can move forward and backward in (direction as shown by the arrows in figure 12) in pilot hole 701b, activity
One stopper slot 732 is had on the side of block 73, refers to Figure 13 and Figure 14, the side of this spacing collar 77 have can be inserted into above-mentioned
Connecting portion 771 in stopper slot 732, active ratchet 75a and the first spring 74b are installed in the connecting portion 771 of this spacing collar.
Above-mentioned compression spring 74a is located at the front side of second substrate 70b, and it is offseted with the one end of the connecting rod 78a being plugged in second substrate,
The other end of connecting rod 78a is offseted with movable block 73.Axle for supporting turntable axle is installed in the axis hole of above-mentioned 3rd substrate 70c
Hold 76b.The second described ratchet 71b is installed in the axis hole of tetrabasal 70d, refers to Figure 15, the ratchet side of the second ratchet
To in opposite direction with the ratchet of the first, the 3rd ratchet, a guide post 78b is arranged in tetrabasal 70d, in this guide post 78b
Inside it is provided with a passage 781b, above-mentioned second spring 74c and detent 75b are installed, in the effect of second spring 74c in passage
Under, detent 75b is offseted with the second ratchet.Above-mentioned 3rd ratchet 71c is installed in the axis hole of the 5th substrate 70e, stops
Ratchet 75c and the 3rd spring 74d is arranged in the slideway 701e of the 5th substrate, and is sealed slideway with plug 79, refers to figure
16, so in the presence of the 3rd spring 74d, blocking pawl 75c is offseted with the 3rd ratchet 71c.
In the presence of above-mentioned drive mechanism, the rotation process of rotating disk is as follows: when transmission bar is transported from top to bottom with template
When dynamic, the lower end of transmission bar enters into the pilot hole of second substrate after the jack on workbench, the through hole on first substrate
In, with transmission bar continue move down, will promote movable block to move on front side of workbench, and then drive spacing collar and active spine
Pawl, makes active ratchet stir the first ratchet, and the first ratchet starts to rotate.But the upper shifting with template, transmission bar with move, because
This transmission bar is interrupted by movable block to the thrust of active ratchet, therefore the first ratchet can only rotate certain angle, that is, really
Protect rotating disk to turn an angle on demand, the semi-finished product completing are made on a machining position, goes at next station, with this Zhou Erfu
Begin, under there is no extra power source, the power that moved up and down using template, so that rotating disk is rotated on demand.Therefore processing cost is lower,
Structure is more compact, simple, and easy to implement.
In above-mentioned rotating disk rotation process, it is not rotated further by after rotateing in place in order to ensure rotating disk, no longer rotates forward, also no longer
Reversion, by the second ratchet and detent and second spring, the 3rd ratchet with stop the cooperation of ratchet and the 3rd spring Lai
Realize.So, when being driven shifting on bar, movable block moves to the rear side of process equipment in the presence of compression spring, now, main
Pawl is with moving afterwards, and compresses the first spring, until active ratchet head drops in the next teeth groove of the first ratchet again.
It is repeated in like this, realize rotating disk and discontinuously rotate.
