As shown in fig. 2 to 3, in the prior art, a long circular hole 411 is formed in a base of a positioning block 41 of a rapid-compression device 4, an adjusting bolt 42 penetrates through the long circular hole 411 to be connected with a platform 3, and during a welding process, the position of the whole rapid-compression device 4 is adjusted by adjusting the fixed position of the adjusting bolt 42 in the long circular hole 411. However, the limitation of this adjustment method is large, and the maximum adjustment distance is only the length of the oblong hole 411, which cannot satisfy the position adjustment of a long distance in the actual welding process.
However, in the present embodiment, fig. 8 is a side view of the side member structure shown in fig. 4, fig. 9 is a front view of the side member structure shown in fig. 4, and fig. 10 is a left side view of the side member structure shown in fig. 4. As shown in fig. 8 to 10, the longitudinal beam 52 has an i-shaped cross section, the fixing member 54 is disposed on the upper wing of the i-shaped structure of the longitudinal beam 52, and the fixing member 54 has a width greater than that of the upper wing of the longitudinal beam 52, so that the fixing plate 545 partially protrudes from the upper wing of the longitudinal beam 52 in the width direction thereof to form a stepped structure. A pressure plate 541 is provided at the stepped structure, and a first end of the pressure plate 541 abuts against the bottom surface of the fixed plate 545 and a second end abuts against the side member 52. In order to enable the pressing plate 541 to push against the fixing plate 545 and the longitudinal beam 52 at the same time, the height of the first end of the pressing plate 541 should be higher than that of the second end, and preferably, the height of the first end of the pressing plate 541 higher than that of the second end is just the thickness of the upper wing of the longitudinal beam 52. When the position of the fixing component 54 on the longitudinal beam 52 needs to be adjusted, the position of the fixing component 54 can be adjusted along the length direction of the longitudinal beam 52 by loosening all the nuts 543, which are matched with the bolts 521, on the fixing component 54, and when the fixing component 54 slides to a specified position, the fixing of the fixing component 54 on the longitudinal beam 52 can be realized by tightening all the nuts 521 on the fixing component 54. In the embodiment, the position of the fixing component 54 can be adjusted randomly along the length direction of the longitudinal beam 52, the adjusting distance range is large, and the positioning requirement of the actual welding process on the B-type beam 6 can be better met.
Specifically, the fixing assembly 54 in this embodiment includes a fixing plate 545 and inclined pressing mechanisms 544, and the inclined pressing mechanisms 544 are mounted on the fixing plate 545, wherein only one inclined pressing mechanism 544 may be mounted on each fixing plate 545, or a plurality of inclined pressing mechanisms 544 may be mounted at the same time, for example, two inclined pressing mechanisms 544 with different pressing directions are mounted on the fixing plate 545 so as to press the b-beam 6 disposed in different directions, and the number and specific arrangement directions of the inclined pressing mechanisms 544 on each fixing plate 545 are not limited in this embodiment.
Specifically, fig. 11 is a front view of the diagonal pressing mechanism shown in fig. 10, fig. 12 is a left side view of the diagonal pressing mechanism shown in fig. 4, and fig. 13 is a top view of the diagonal pressing mechanism shown in fig. 4. As shown in fig. 11 to 13, the inclined pressing mechanism 544 in the present embodiment includes a base 5441 and an inclined pressing mechanism upper body 5442 provided on the base 5441. The inclined pressing mechanism upper body 5442 can be connected with the base 5441 in a detachable connection mode such as insertion connection and the like, so that the tire of a welding part after later welding is finished can be removed. Especially, when the b-type beams 6 are densely arranged in the welding process, no redundant transverse space is reserved for the inclined pressing mechanism 544 to perform transverse adjustment in the pressing and loosening processes, the upper body 5442 of the inclined pressing mechanism and the base 5441 can be directly and quickly separated in the longitudinal direction through a detachable connection mode such as insertion connection, and the tire discharging time after the welding is finished is greatly saved.
Fig. 14 is a schematic view of the upper body of the inclined pressing mechanism shown in fig. 11. As shown in fig. 14, the upper body 5442 of the inclined pressing mechanism in this embodiment includes a screw rod socket 54422, a screw rod 54423 engaged with the screw rod socket 54422, and a movable pressing head 54424 disposed at a lower end of the screw rod 54423. Optionally, the movable pressing head 54424 is made of an elastic material, such as rubber, one end of the movable pressing head 54424 is provided with a bayonet, and the lower end of the screw rod 54423 is provided with a chuck which is just in bayonet connection with the bayonet on the movable pressing head 54424. In the process of welding different structures, the specifications of the B-shaped beam are different, and the effective positioning of the B-shaped beams with different specifications can be realized by replacing the movable pressure head 54424 at the lower end of the screw rod 54423. In addition, a screw cap 54426 can be arranged at the end of the screw rod 54423 which is not connected with the movable pressure head 54424, so that the screw rod 54423 can be adjusted more conveniently. After the b-beam is placed at a designated position, by rotating the screw cap 54426 to make the screw rod 54423 move downward along the axis of the screw rod female seat 54422, when the movable ram 54424 just contacts the b-beam, a force pressing the b-beam 6 against the movable ram 54424 can be applied to the b-beam 6, and then the screw cap 54426 is further rotated to make the movable ram 54424 press the b-beam 6 further.
Optionally, the upper inclined pressing mechanism body 5442 in this embodiment is connected to the base 5441 in an inserting manner, wherein a cylindrical pin 54421 is disposed on the nut lead base 54422 of the upper inclined pressing mechanism body 5442, a mounting hole 54411 matched with the cylindrical pin 54421 is disposed on the base 5441, and a cylindrical pin fixing groove 54425 is disposed along a circumferential direction of one end of the cylindrical pin 54421 matched with the mounting hole 54411. When the cylindrical pin 54421 is inserted into the mounting hole 54411, the set screw 5443 can be inserted into the screw hole on the base 5441, so that the set screw 5443 can be exactly clamped in the cylindrical pin fixing groove 54425, and the axial fixation of the upper body 5442 of the inclined pressing mechanism can be realized. After welding, the upper body 5442 of the oblique pressing mechanism can be separated from the base 5441 only by taking out the set screw 5443 from the screw hole on the base 5441.
Referring to fig. 3, in the prior art, a b-shaped beam 6 is usually placed on a platform 3 and is pressed by a rapid pressing device 4, wherein a pressing head of the rapid pressing device 4 presses an upper end of the b-shaped beam 6, and a positioning block 41 abuts against a lower end of the b-shaped beam 6. However, due to the special structure of the b-shaped beam 6, the b-shaped beam 6 is easy to turn over due to the pressing mode, and is not clamped in the horizontal direction, so that slippage is easy to occur in the welding process, and the welding quality is seriously affected.
However, the movable ram 54424 of the present embodiment is provided with a first pressing surface 54427 and a second pressing surface 54428, wherein the first pressing surface 54427 is a horizontally disposed ground plane, and the second pressing surface 54428 is a vertically disposed plane. When the movable ram 54424 presses the b-beam 6, the first pressing surface 54427 presses the bottom surface of the b-beam 6, and the second pressing surface 54428 presses the side surface of the b-beam 6. This implementation is when compressing tightly second type roof beam 6, has all carried out effectual location to second type roof beam 6 level and two vertical directions simultaneously, and because compress tightly the position for second type roof beam 6 lower corners, has avoided the problem that quick closing device 4 among the prior art takes place to turn on one's side easily when compressing tightly second type roof beam 6 up end effectively.
With reference to fig. 11, optionally, an included angle formed by the axis of the screw rod 54423 and the vertical direction in this embodiment is 45 degrees, when the movable pressing head 54424 presses the b-beam 6, the pressing force applied to the side wall of the b-beam 6 is equal to the pressing force applied to the bottom surface, and the resultant force direction of the resultant force inevitably passes through the inflection point at the lower corner of the b-beam 6, so that the resultant force does not generate a tilting moment on the b-beam 6, so that the b-beam 6 is fixed more stably and reliably during the welding process, and the welding quality of the b-beam is further improved.
Referring to fig. 5 to 7, in this embodiment, a plurality of vertical columns 53 may be further disposed below the long cross beams 51, where the vertical columns 53 are used to support a frame structure formed by the longitudinal beams 52 and the long cross beams 51, for example, one vertical column 53 may be disposed along both ends of each long cross beam 51, or one vertical column 53 may be disposed at both ends and a middle point of each long cross beam 51, and the number and specific disposition positions of the vertical columns 53 disposed on each long cross beam 51 are not limited in this embodiment. The upright 53 may be fixed to the ground by expansion bolts, and the upright 53 and the long beam 51 may be connected by bolts.
Optionally, the long cross beam 51, the longitudinal beam 52 and the upright 53 are all made of i-steel, and the cross section of the i-steel is of an i-shaped structure. By adopting the I-shaped structure, the weight of the whole welding tool can be reduced while the long cross beam 51, the longitudinal beam 52 and the upright column 53 have enough strength.
In the embodiment, the frame structure of the longitudinal beam adjustable in the length direction of the long cross beam and the modular structure of the fixing component adjustable in the length direction of the longitudinal beam are adopted, so that the fixing component of the second-type beam can be adjusted and fixed randomly along the transverse direction and the longitudinal direction in the welding process, and the universality of the welding tool is improved. In addition, compress tightly the B type roof beam through oblique hold-down mechanism, not only can realize more reliable effect that compresses tightly to guarantee welding quality, can also promote the efficiency that the B type roof beam welding back came out the child greatly.

The welding method of the embodiment is to weld through the welding tool in the first embodiment. As shown in fig. 15 to 16, the welding method of the present embodiment includes:
step 201, adjusting the position of the longitudinal beam on the long cross beam according to the position requirement of the side pillar of the side wall of the vehicle body, and fixing the longitudinal beam on the long cross beam.
Specifically, the longitudinal beams 52 are respectively and sequentially installed from two ends of the long cross beam 51 by taking the center line of the vehicle body as a reference, and the position of each longitudinal beam 52 on the long cross beam 51 is adjusted and fixed according to the position requirement of each side column 1 in the drawing of the side wall product of the vehicle body. After welding, the side wall is deformed and shrunk to a certain extent under the action of welding thermal stress, so that the specific technological requirements of side wall welding of different vehicle types are considered during positioning, and corresponding technological allowance is reserved at the position of a window.
Step 202, adjusting the fixing component on the longitudinal beam according to the position requirement and the upper deflection requirement of the cross beam of the side wall of the vehicle body, and fixing the fixing component on the longitudinal beam.
Specifically, according to the position requirement and the upper deflection requirement of each cross beam 2 in the drawing of the car body side wall product, the fixing component 54 on each longitudinal beam 52 is adjusted and fixed on the longitudinal beam 52. Because the side wall of the vehicle body is in a flat state during welding and is in a vertical state during actual installation on the vehicle body, the whole body of the side wall of the vehicle body has larger mass, and after the side wall of the vehicle body is placed from the flat state to the vertical state, the side wall of the vehicle body can deform downwards under the action of the gravity of the side wall of the vehicle body. Therefore, when the beam b of the side wall of the car body is arranged, an upper deflection is usually set to overcome the deformation caused by the self weight of the side wall of the car body. Wherein, the upper deflection refers to the distance of the central position of the beam 2 deviating from the connecting line of the two ends of the beam. For example, if the process requires that all the cross beams 2 have an upper deflection of 13mm over the entire length, the fixing assemblies 54 for fixing the cross beams 2 on each longitudinal beam 52 are adjusted accordingly, so that all the cross beams 2 have an upper deflection of 13mm before welding. Optionally, in order to increase the overall strength and rigidity of the vehicle body side wall, a rectangular process beam may be added to the upper portion of the vehicle body side wall, and the rectangular process beam should also be set to the same upper deflection value as that of the other cross beams when being welded.
And 203, pressing the side column and the cross beam of the side wall of the vehicle body on a fixing plate of the fixing component by using an inclined pressing mechanism on the fixing component.
Specifically, after the side posts 1 and the cross beam 2 are placed, the side posts 1 and the cross beam 2 are pressed against the fixing plate 545 of the fixing assembly 54 by the inclined pressing mechanism 544 of the fixing assembly 54. Optionally, after the fixing, it is also possible to check again, by means of a corresponding measuring tool, whether the fixed frame structure meets the process requirements.
And step 204, welding the joint position of the side column of the side wall of the vehicle body and the cross beam of the side wall of the vehicle body.
After confirming that the frame structure composed of the side columns 1 and the cross beams 2 meets the process requirements, welding the frame structure at the joint position needing welding, wherein the welding operation can be completed by a spot welding robot or manually.
Alternatively, after welding, the inclined pressing mechanism upper body 5442 may be separated from the base 5441, and then the sidewall of the vehicle body may be integrally lifted out of the tire.
This embodiment when welding to different motorcycle types, can only need adjust the longeron of size change department alone and the position of fixed subassembly on it can, need not all adjust all location closing device, the time of changeing the frock again when having shortened the motorcycle type conversion greatly.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
