Fig. 2 is the structural representation of clamp；
Fig. 3 is the structural representation of positioning tool.
Embodiment
With reference to embodiment, the present invention will be further described.
Embodiment
As shown in Figure 1-Figure 3, a represents the left longeron signal placed in figure, and b represents the right vertical beam signal placed.Set up quiet
Sliding block 1, movable slider 2 is set up, the two centre is connected using the first oil cylinder 3, and quiet sliding block and movable slider can be arranged on an installing plate,
Quiet sliding block installing plate is fixedly mounted, the movable clamping of movable slider on a mounting board, the 3 forward and backward setting of the first oil cylinder, totally two sets of oil pressure
System, in addition to control panel, the operating system that the first oil cylinder connects through control panel with control panel control the first oil cylinder
Work, operator is manipulated by panel and operate two sets of oil hydraulic systems while to work, and its first oil cylinder stretches, with this
To drive moving back and forth for movable slider 2, then the longeron placed also while carries out displacement above, so as to reach control frame assembly
The purpose for opening grade size.
Symmetrically two guide rails 4 are set up in quiet sliding block 1 and the upside of movable slider 2, in order to are moved back for clamp 5
Dynamic, clamp 5 sets up four pairs altogether on quiet sliding block 1 and movable slider 2, adapts to the frame assembly assembly work of different length, clamp 5
Open the size of shelves after being clamped according to different frame assemblies and adjust back and forth, can preferably ensure a grade size of opening for frame assembly,
If longeron has slight bad quality problems as bent, mild distortion etc., after the clamping of clamp 5, it can be corrected, when
After the completion of middle connecting cross beam part assembling, its bad quality problems can obtain effective solution, and the purpose for setting up clamp is
In the state of clamp clamping, bending is not present in the outside of belly of left and right longeron, or by bending control in minimum zone, so as to reach
The uniformity of shelves is opened before, during and after to frame assembly.
Positioning tool 6 is set up in the leading portion of equipment, is set up on quiet sliding block 1 and movable slider 2, equipment center line position pair
Claim to place.Before frame assembly is assembled, left and right longeron from last process handling to this station after be put into before four pairs of clamps 5,
Immediately using special alignment pin insert three faces in a state of excitement hole when the positioning hole set up in, left and right longeron be put into simultaneously it is symmetrical calmly
In the frock 6 of position, clamp clamps, in order to ensures the big of forward and backward the bridge diagonal and front section of vehicle frame and back segment of frame assembly
Diagonal critical size ensures the total quality of frame assembly in the margin of tolerance.
Shown in Fig. 2 for the detail view of clamp 5, clamp base 5-1 is set up on clamp 5, the base for the installation of other parts
Plinth part, sets up side cushion block 5-2 on clamp base 5-1, and side cushion block is act as：When assembling different type, difference open a grade size
Frame assembly when, can be adjusted using various sizes of side cushion block, as to drive the consistent vehicle frame of shelves total before, during and after installing
Into the side cushion block of same thickness size being used to enter the regulation that driving frame opens shelves, grade size uniformity opened before, during and after guarantee and is caused；
Assembling is when to open shelves be front wide and rear narrow frame assembly, front section bicycle frame open grade size greatly shelves are carried out out using relatively thin side cushion block
Regulation, back segment vehicle frame opens that grade size is small to be adjusted using thicker side cushion block.Bottom cushion block 5-3 is set up again, four
The thickness of bottom cushion block 5-3 to being set up on clamp is consistent, and when left and right longeron is placed on clamp, lower aerofoil is respectively positioned on one
On individual horizontal plane, prevent frame assembly from the phenomenon integrally distorted after the completion of assembling be present.Dynamic model block 5-4 is set up, by the second oil
Cylinder 5-5 is driven, and the second oil cylinder is connected with control panel, and is controlled by control panel, is acted when the second oil cylinder stretches out
For clamped condition, the movement control vehicle frame of movable slider 2 opens shelves, starts to assemble, the contraction of the second oil cylinder, dynamic model block are operated after the completion of assembling
5-4 unclamps the longeron clamped, and the lower road sequence of lifting transhipment carries out assembly work.Dynamic model block may be designed as L-type structure, and dynamic model block is with indulging
One termination of beam contact sets the part with the effect of certain buffer shock-absorbing, the part to be carried after clamping longeron by the second oil cylinder
For pretightning force, it is more firm to clamp longeron.
The details for positioning tool 6 shown in Fig. 3, symmetrically set up on quiet sliding block 1 and movable slider 2, in positioning tool
Upper setting detent part 6-1, for placing 6-2 alignment pins, for alignment pin through Overheating Treatment, hardness is high, ensures to make for a long time
It is not easy to wear during, deformation etc. undesirable element and influence the critical sizes such as the diagonal of frame assembly.Alignment pin and positioning
The diameter of groove contact portion is consistent, ensures the accuracy of positioning with this, ensures the keys such as the diagonal of frame assembly
Size.
The present invention can open frame assembly the equipment that shelves, diagonal etc. are controlled, and be controlled using PLC, produce
During frame assembly, input corresponding frame assembly and open gear number value, click on spacing, you can starting device clamps left and right longeron, oil cylinder
Mobile clamp of starting working is worth as defined in, and set up a pair of alignment pins, the left and right longeron of vehicle frame is positioned, its side
Formula is when longeron programs, and in left and right longeron identical position respectively plus φ 30mm or φ 40mm hole, is being assembled
During frame assembly, left and right longeron alignment pin is inserted into this hole, is put into pin tool, positioned with this.So may be used
Effectively to control the diagonal of frame assembly, ensure that vehicle frame its outward appearance after the completion of assembling is in regular rectangle.
1st, employ clamp to be clamped, PLC input numerical value is controlled, it is ensured that opens shelves before, during and after frame assembly
Size is in certain scope, and for existing frame assembly after the completion of assembling, its vehicle frame opens grade size within ± 2mm.
2nd, after carrying out positioning hole positioning to left and right longeron using positioning tool, the forward and backward bridge diagonal of vehicle frame is can be controlled in
Within 0-3mm, the big diagonal of front section of vehicle frame to back segment is can be controlled within 4mm, while the axiality of frame assembly leaf spring is adopted
It can be passed through during with special detection tool detection.
3rd, clamp sets up bottom cushion block, and the bottom cushion block of four pairs of clamps ensure that frame assembly in same level
The levelness of above and below, when upper professional detection platform detects, the levelness of its above and below is qualified, within 0-3mm.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
