Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now comparison brief description this
Bright specific embodiment.
As shown in Figure 1 and Figure 2, the present invention proposes a kind of rotating disk angle adjustment and locking device 100, and described rotating disk angle is adjusted
Whole and locking device 100 includes base 9, and base 9 is provided with centre bore 91；It is arranged on base the lower rotational of one rotating disk 1
Centre bore 91 in；The base 9 of neighbouring rotating disk 1 side is provided with axis pin base 8 (that is: the axis direction of axis pin base 8 being vertically arranged
Parallel with the axis direction of the centre bore 91 of base 9), one end of a screw rod 2 is articulated with this axis pin base 8；On described rotating disk 1 side wall
It is fixed with projection 3 (that is: the bearing of trend line of this projection 3 the turning by this rotating disk 1 being extended along rotating disk 1 radial direction
Dynamic center), described projection 3 is provided with the u shape groove 31 that an opening points to projection outer end, and described screw rod 2 is arranged in this u shape groove 31
In, in this projection 3 both sides and be located at this screw rod 2 on be respectively provided with fasten this projection 3 double nut 21；Another positioned at rotating disk 1
The corner oil cylinder 4 of this rotating disk 1 of one driving rotation is connected with the side wall of side, the cylinder body 41 of described corner oil cylinder 4 is articulated with institute
State on base 9, the piston rod 42 of this corner oil cylinder 4 is articulated with the side wall of rotating disk 1；This corner oil cylinder 4 is provided with displacement transducer
5.
In the present embodiment, during the adjustment of normal corner, this rotating disk 1 is the corner model at positive and negative 3 degree to rotating disk 1
Enclose interior adjustment, in described normal corner adjusting range, as shown in figure 3, axis pin base 8 axis and projection 3 are apart from a, center
Hole 91 axis and projection 3 constitute a right angled triangle apart from b and axis pin base 8 axis and centre bore 91 axis apart from c, its
In: a, b are right-angle side, and c is hypotenuse；Rotating disk 1 (that is: adjusts in positive and negative 3 degree of angle range during the adjustment of normal corner
When), two acute angles of right angled triangle and the length of two right-angle side a, b can produce small change, and the length of hypotenuse c does not have
Change；Still a right angled triangle is constituted between above-mentioned 3 points after being adjusted in place；Therefore, this turn in present embodiment
Disk adjusts locking device and is fully able to meet the needs of above-mentioned rotating disk corner adjustment.
As shown in figure 3, when carrying out the adjustment of rotating disk corner using described rotating disk angle adjustment and locking device 100, first, will
Two groups of double nuts 21 on screw rod 2 unclamp；Start corner oil cylinder 4, rotated by piston rod 42 driving rotating disk 1 of this corner oil cylinder 4,
To adjust rotating disk corner；First screw rod 2 can also be removed from u shape groove 31, again screw rod be put after rotating disk corner is adjusted in place
Enter in u shape groove 31；In the present embodiment, the afterbody of corner oil cylinder 4 is provided with displacement transducer 5, by geometry computations, root
Corner (the skill that this part all knows for those skilled in the art of rotating disk can accurately be calculated according to the stroke of measurement corner oil cylinder
Art, will not be described here)；After the corner of rotating disk 1 is adjusted in place, the double nut 21 positioned at projection 3 both sides is tightened, to compress
Projection, now, projection 3 be on new position with screw rod 2 be mutually perpendicular to lock state (that is: a, b side be in new vertical
Position)；According to mechanism principle and rod member geometrical arrangements relation, screw rod 2 is relatively fixed with projection 3, thus locks rotating disk 1.
From the above mentioned, the rotating disk angle adjustment of the present invention and locking device, its compact conformation, reliable lock, adjustment is flexible,
Maintenance is easy, low cost of manufacture；Corner oil cylinder afterbody is provided with displacement transducer it is easy to detect the rotational angle of rotating disk, can root
According to setting value, realize the precise control of rotating disk rotational angle；According to mechanism principle and rod member geometrical relationship, screw rod rotation is different
Angle, double nut different position of movement on screw rod, the tune of various operating angles in adjusting range for the rotating disk can be met
Whole operation.This device applies also for rotating disk and rotates in certain operating angle scope and need the other locked to set in circumferencial direction
Standby.
Further, in the present embodiment, described projection 3 is connected with fixed seat 32, described fixed seat 32 is fixing
It is connected on the side wall of rotating disk 1；Rotating disk 1 side wall is provided with one with this fixed seat 32 bottom surface identical deep gouge 11, and this fixed seat 32 is blocked
And if be fixed in this deep gouge 11, thus, it is possible to be accurately positioned the position of rotating disk 1 and projection 3, prevent between rotating disk 1 and projection 3
Produce relative movement and affect the accuracy of corner adjustment.
In order that have more to be firmly fixed between screw rod 2 and projection 3 being connected, in the present embodiment, positioned at two groups
It is provided with the ball pad 22 for fixing projection 3 between double nut 21.
As shown in figure 1, in the present embodiment, the cylinder body 41 of corner oil cylinder 4 is by the way of middle gudgeon swings and bottom
Seat 9 connection；Described rotating disk side wall is provided with a contiguous block 12, and the piston rod 42 of described corner oil cylinder 4 is articulated with this contiguous block 12.
When changing pine rod roller, described rotating disk 1 needs to carry out wide-angle adjustment, and now, screw rod 2 can swing to inoperative
State (that is: the u shape groove 31 of screw rod 2 and projection 3 is departed from), to avoid the movement line of rotating disk 1；Because screw rod 2 with projection 3 is
Connected by u shape groove 31, when both depart from very convenient it is not necessary to carry out the dismounting of complexity, as shown in Figure 4 it is only necessary to will
Double nut 21 unclamps, and screw rod 2 is removed from u shape groove 31.
The rotating disk angle adjustment of the present invention and locking device, rotating disk is under the driving of corner oil cylinder in the range of operating angle
Rotate；Screw rod one end is hinged with axis pin base, and the other end is connect with rotating disk, (refers mainly to screw rod, rotating disk, gear in the form of connecting rod
The structure that block is connected forms a bar linkage structure after simplifying) locking pine rod roller rotating disk；This screw rod swings in the u of projection around axis pin base
In shape groove, screw rod can swing with rotation in the range of operating angle for the rotating disk, after turntable rotation to operating position, passes through
Tighten the double nut being arranged on screw rod and compress projection, and then lock rotating disk；Whole device compact conformation, locking is stable, can
Lean on, flexibly, maintenance is easy, low cost of manufacture for adjustment.This device is applied to rotating disk and rotates in certain operating angle scope, and circumference
Direction needs the equipment of locking.
The foregoing is only the schematic specific embodiment of the present invention, be not limited to the scope of the present invention.Any
