Crossbeam 2033 forms a groined type bracket.Each component of front frame 200 is located in special-purpose vehicle front frame by bottom surface in a manner of upward
Assembly or fitting table on.
It herein, is longitudinal direction (front-rear direction) by the direction definition of Y-axis meaning in Fig. 2, X-axis direction is defined as cross
To direction (left and right directions), Z axis direction is positioned at as short transverse (up and down direction).
The assembly or fitting table 100 of special-purpose vehicle front frame of the invention includes pedestal 101, for the front beam of position nose beam 201
Positioning mechanism 10, for the small girder 202 of positioning and clamping two centering clamp system 23, well cabinet frame positioning mechanism 31, crossbeam it is fixed
Position mechanism 41 and roller-way mechanism 24 is rotated and upgraded for promote, decline small 202 height of girder.
It should be noted that, the signified small girder station to be positioned of the present invention refers to small for positioning on pedestal 101 herein
The region of girder；Signified front beam station to be positioned of the invention refers to the region that position nose beam is used on pedestal 101.
Front beam positioning mechanism 10 include be arranged in the two of 101 front end of pedestal hold out against cylinder 11 and respectively with front beam 201
Two corners lock cooperation two corners lock positioning device 12.Each angle lock position device 12 includes cylinder and the protrusion with angle lock cooperation.
Under the driving of cylinder, protrusion cooperates with the hole in the lock of angle, realizes positioning.Two, which hold out against the interval of cylinder 11, is laid in front beam 201
Length direction on.Wherein, front beam 201 is located in front beam by front beam positioning mechanism 10 in a manner of upward by bottom surface and waits for
On positional stations.
Two small girders 202 pass through fixed rollgang 25 and rotate and upgrade roller-way mechanism 24 to be inputted from the rear end of pedestal 101
To the assembly or fitting table 100.Rotating and upgrading roller-way mechanism 24 includes twice roller-way, and each roller-way is for conveying one small girder 202.Often
One roller-way includes multiple rotating and upgrading component 241 along what 101 longitudinal direction of pedestal was intervally arranged.Rotating and upgrading component 241 includes
Cylinder, connecting shaft 2411 and roller 2412, roller 2412 are connect with connecting shaft 2411 by connecting plate, and cylinder is drivingly connected axis
2411 rotations, and then the roller 2412 connecting with connecting plate is driven to be promoted or declined.
Roller-way mechanism 24 is promoted for conveying, being promoted or declining two small girders 202.Specifically, small girder 202 is with bottom surface court
On mode when being inputted by fixing rollgang 25, rotate and upgrade the stretching of roller-way mechanism 24, make the upper surface of its roller 2412 with
The upper surface of fixed rollgang 25 is concordant, facilitates small girder 202 that can be transferred to from fixed rollgang 25 as a result, and rotates and upgrades
In roller-way mechanism 24.When small girder 202 is by rotating and upgrading the conveying of roller-way mechanism 24 in place, rotate and upgrade under roller-way mechanism 24
Drop, small girder 202 are fallen on centering clamp system 23.
The longitudinal direction of pedestal 101 is provided with three sets of centering clamp systems 23, respectively corresponds before clamping small girder 202
End, intermediate position and rear end.Every suit includes two centering clamp systems 23, is respectively used to clamp two small girders 202.In conjunction with figure
Shown in 3, Fig. 3 is the structural schematic diagram of centering clamp system.Centering clamp system 23 includes motor 231, is arranged on motor 231
Side is used to support the support 232 of small girder and two gripping blocks 233 being arranged on support 232, and two gripping blocks 233 are oppositely arranged,
And can be moved toward one another in transverse direction under the driving of motor 231 or back movement, the width of two small girders 202 is determined as a result,
And then determine the width of front frame.For example, when small girder 202 has just been fallen on the support 232 in the centering clamp system 23, two
Gripping block 233, which moves toward one another, clamps small girder 202, and small girder 202 is located in pre-position.Similarly, the small master of the other side
Beam 202 is also located in pre-position under the action of to middle clamp system 23.It whereby, will by above-mentioned centering clamp system 23
The width of two small girders 202 is limited in predetermined distance range.
The assembly or fitting table 100 of special-purpose vehicle front frame further includes the first vertical pressure for compressing two small girders 202 in the height direction
Tight mechanism 21 and the second vertical pressure-tight mechanism 22.First vertical pressure-tight mechanism 21 is two, two the first vertical pressure-tight mechanisms 21
It is laid in the side of two small girder stations to be positioned respectively and close to front beam station to be positioned.The two of front beam station to be positioned
End is respectively arranged with end press elastic parts, in the initial state, be placed on front beam on front beam station to be positioned with
The spring that end presses elastic parts keeps dynamic equilibrium, in the pushing front beam 201 of the first vertical pressure-tight mechanism 21, front end
The spring-compressed of 201 lower section of beam, front beam 201 can move down.When first vertical pressure-tight mechanism 21 pushes, front beam is first contacted
201, it contacts simultaneously later and compresses front beam 201 and small girder 202.Specifically, two first vertical pressure-tight mechanisms 21 are in front end
The junction of beam 201 and small girder 202 compresses front beam 201 and small girder 202.Because two small girders 202 be with bottom surface upward
Mode is input in assembly or fitting table 100, and front beam 201 is also positioned on a predetermined position in a manner of upward by bottom surface, therefore, is led to
Crossing two first vertical pressure-tight mechanisms can realize that front beam 201 and 202 bottom surface of small girder flush.
Second vertical pressure-tight mechanism 22 is two sets, and every suit includes being respectively used to compress the two second of two small girders 202 to hang down
Straight hold-down mechanism 22, wherein it is a set of for compressing the intermediate position of two small girders 202, it is another set of for compressing two small girders 202
