The specific embodiment
As shown in Figures 1 to 5, a kind of automobile front subframe soldering cramping apparatus of the utility model, comprise clamp base 1, the work top of clamp base 1 is provided with two soldering positioning devices, detent mechanism 11 and clamping device 10, fore sub frame is placed on the locating surface that detent mechanism 11 forms, the structure of clamping device 10 is same as the prior art, surrounding at fore sub frame is fixed fore sub frame clamping, clamping device 10 is provided with six altogether, wherein two are distributed in both sides, fore sub frame middle part, remain four both sides that are distributed in respectively fore sub frame two ends.Be illustrated in figure 6 fore sub frame, apparatus for welding and positioning is for fore sub frame being positioned in the time being welded, soldering positioning device comprise with fore sub frame on the suitable alignment pin of locating hole 13 and for several installing holes of alignment pin are installed of being welded, alignment pin insert in installing hole and with installing hole be matched in clearance.The position of each installing hole respectively with a kind of fore sub frame of vehicle on the aligned in position of the locating hole 13 that is welded, thereby can be by changing the position of alignment pin, make this soldering cramping apparatus can be applicable to being welded of fore sub frame of corresponding vehicle.
Specifically, this soldering cramping apparatus can be applicable to being welded of fore sub frame of A, two kinds of vehicles of B.Soldering positioning device is divided into the first soldering positioning device 2 and second soldering positioning device 9 of clamping device 10 both sides that are distributed in clamp base 1 centre position place.As shown, the first soldering positioning device 2 and the second soldering positioning device 9 include for positioning base fixing in clamp base 17, be provided with a bearing 8 and two cushion blocks 12 at the end face of positioning base 7, positioning base 7 is installed in clamp base 1 by screw, be easy for installation and removal, bearing 8 and two cushion blocks 12 are installed on positioning base 7 by screw, and two cushion blocks 12 are positioned at the same side of bearing 8, and cushion block 12 plays the effect of supporting and regulating height.
The first soldering positioning device 2 and the second soldering positioning device 9 are arranged side by side and are symmetry in clamp base 1, on the bearing 8 of the first soldering positioning device 2 and the second soldering positioning device 9, be respectively provided with two installing holes, be respectively with the fore sub frame of A vehicle on two locating hole 13 aligned in position that are welded A vehicle installing hole 5 and with the fore sub frame of B vehicle on the B vehicle installing hole 6 of two locating hole 13 aligned in position that are welded, corresponding alignment pin is divided into the A vehicle alignment pin 3 that is suitable for A vehicle and the B vehicle alignment pin 4 that is suitable for B vehicle.In the time being welded A vehicle fore sub frame, two A vehicle alignment pins 3 are inserted in two A vehicle installing holes 5, in the time being welded B vehicle fore sub frame, two B vehicle alignment pins 4 are inserted in two B vehicle installing holes 6.
