As shown in Figure 1 to Figure 3, the embodiment of the invention provides a kind of steering curved boom fixtures comprising pedestal 400 clamps
Mechanism 100, the first positioning mechanism 200, the second positioning mechanism 300 and control mechanism 500；Wherein, clamp system 100 includes being used for
Clamp the upper fixture block 111 and lower fixture block 121 for turning to the axle journal 11 of curved boom 10；First positioning mechanism 200 includes clamping protrusion 211,
It clamps protrusion 211 and cooperates with the boss 12 turned on curved boom 10；Second positioning mechanism 300 includes clamping column 320 and locating piece
310, locating slot 311 is provided on locating piece 310, and the center of locating slot 311 is aligned with the center of clamping column 320, turns to curved boom
10 fist portion 13 is fastened in locating slot 311, and clamping column 320 is pressed on the one side for deviating from locating piece 310 in fist portion 13；Control machine
Structure 500 is for controlling clamp system 100, the first positioning mechanism 200 and the movement of the second positioning mechanism 300.
In it will turn to 10 clamping process of curved boom, it can first drive clamp system 100 to work, make upper fixture block 111 and lower folder
Block 121 is clamped on the axle journal 11 for turning to curved boom 10, to realize the pre-determined bit for turning to curved boom 10, then passes through the first positioning mechanism
200 position the boss 12 turned on curved boom 10, are pressed on clamping protrusion 211 on boss 12, while are set to the card of fist portion 13
In the locating slot 311 of locating piece 310, it is pressed on clamping column 320 in fist portion 13, this completes to 10 entirety of steering curved boom
Clamp positioning；Wherein, by the way that locating slot 311 is arranged, it ensure that stability of the fist portion 13 in position fixing process, it is therefore prevented that fist portion 13
Shake, meanwhile, by be arranged clamping column 320, realize the accurate positioning to position of opening in fist portion 13, which thereby enhance fist
The position precision of hole location in portion 13 ensure that and turn to the subsequent processing quality of curved boom 10.
Wherein, control mechanism 500 can be sequence valve, and sequence valve is the Hydraulic Elements of standard, can be controlled by sequence valve
The sequence of movement of clamp system 100 processed, the first positioning mechanism 200 and the second positioning mechanism 300, it can first drive clamp system
Then 100 movements drive the first positioning mechanism 200 and the second positioning mechanism 300 to move.
Further, as shown in figure 4, clamp system 100 includes first driving device 130, the first rack gear 140, the second rack gear
160, gear 150, upper holder block 110 and lower lock block 120；The fixing end of upper holder block 110 and the driving portion of first driving device 130 are solid
Fixed connection, upper fixture block 111 are fixed on the pinching end of upper holder block 110；First rack gear 140 and first driving device 130
Driving portion is fixedly connected；Second rack gear 160 is fixed on lower lock block 120,140 position of the second rack gear 160 and the first rack gear
It is oppositely arranged；Gear 150 is engaged with the first rack gear 140 and the second rack gear 160 simultaneously.Wherein, first driving device 130 can be
Cylinder, the driving portion of first driving device 130 can be the piston rod of cylinder, when piston rod pushes upper holder block 110 to move downward
When, since the first rack gear 140 is connected with piston rod, the first rack gear 140 can be moved synchronously with piston rod, and due to gear 150
Position immobilize, when the first rack gear 140 to movement when, the first rack gear 140 can drive gear 150 counterclockwise (such as Fig. 4 institute
Show visual angle) rotation, and since gear 150 is engaged with the second rack gear 160, thus gear 150 can be by the rotational motion of itself turn
The linear motion for turning to the second rack gear 160 moves upwards the second rack gear 160, and then moves upwards lower lock block 120, thus
The pressing for realizing upper holder block 110 and lower lock block 120 realizes the compression to the axle journal 11 for turning to curved boom 10.
Specifically, as shown in Figures 2 and 3, the first positioning mechanism 200 includes the second driving device 230, pressing plate 210 and branch
Dagger 220；One end of pressing plate 210 is connect with the driving portion of the second driving device 230, is clamped protrusion 211 and is fixed at pressing plate
On 210 other end, the axis of support column 220 is overlapped with the axis for clamping protrusion 211, and support column 220 is supported in boss 12
On lower end surface.Wherein, the second driving device 230 can be rotary oil cylinder, can make to clamp protrusion by the driving of rotary oil cylinder
211 are pressed on the upper surface of boss 12, while support column 220 can be supported on the lower end surface of boss 12, from there through folder
The cooperation of tight protrusion 211 and support column 220 ensure that the reliability for turning to the support positioning of curved boom 10.In addition, for the ease of control
System, clamping column 320 can also realize compression movement by rotary oil cylinder.
Wherein, as shown in figures 1 and 3, it is to be understood that turn to and be provided with hole on the boss 12 of curved boom 10, in order to keep away
Exempt to shake after boss 12 positions, the end face of support column 220 can be arcwall face, which supports the hole on boss 12
Edge, it is possible thereby to the cooperation position in the hole on arcwall face and boss 12 generates the component on horizontal and vertical direction, from
And the constraint of power can vertically and horizontally provided to boss 12, it effectively prevents turning to after curved boom 10 positions and send out
It is raw to shake.
As shown in Fig. 2, Fig. 3 and Fig. 5, the second positioning mechanism 300 further includes mounting base 330 and positioning stud 340, mounting base
It is provided with installation protrusion 331 on 330, through-hole is provided on locating piece 310, through-hole is set in installation protrusion 331；Installation protrusion
Threaded hole is provided in 331, positioning stud 340 is fixedly connected after passing through through-hole with threaded hole；The end of positioning stud 340 is arranged
There is limit plate 341, limit plate 341 and the bottom surface gear of locating slot 311 connect.It is thus achieved that between locating piece 310 and pedestal 400 can
Dismantling connection, when the locating slot 311 on locating piece 310 causes precision to reduce because of abrasion, can dismounting and change at any time, it is convenient
It uses.
Further, as shown in Figures 2 and 3, due to turn on curved boom 10 part between fist portion 13 and boss 12 away from
From longer, in order to reduce the shake of the part in clamping process, which further includes the first supporting mechanism 600,
First supporting mechanism 600 is fixed on pedestal 400, and the first groove is provided on the first supporting mechanism 600, and the first groove is used
In the position being supported on steering curved boom 10 between fist portion 13 and boss 12.
Further, which can also include the second supporting mechanism 700, and the fixation of the second supporting mechanism 700 is set
It sets on pedestal 400, the second groove is provided on the second supporting mechanism 700, the second groove is used to support on turning to curved boom 10
Position between axle journal 11 and boss 12.When that will turn to curved boom 10 and be placed on the steering curved boom fixture, can pass through
Second supporting mechanism 700 realizes pre-determined bit, in order to subsequently through the first positioning mechanism 200 and the progress of the second positioning mechanism 300
It is accurately positioned.
Steering curved boom fixture provided in an embodiment of the present invention, it is fixed by setting clamp system, the first positioning mechanism and second
Position mechanism, realizes the positioning to curved boom is turned to, and ensure that the stability for clamping positioning；Meanwhile by the way that locating slot is arranged, guarantee
