At the same time, in this embodiment, the first mounting frame 11, the first driving cylinder 31 and the first positioning clamping mechanism 21 can be arranged accordingly according to the specific structure of A-pillar 51 and C-pillar 53, Figure 3 The structural diagram shown may correspond to the A-pillar 51, Figure 4 The structural diagram may correspond to the B-pillar 52 .

At the same time, the two second driving cylinders 32 can respectively drive the two second positioning and clamping mechanisms 22 to move towards each other, so that the two second positioning and clamping mechanisms 22 are respectively away from the B-pillars 52 of the two side enclosure assemblies 5. That is, during the overall assembly of the automobile, the mounting crossbeam 18 can be placed on the top of the automobile, and the second mounting frame 12 can extend into the interior of the automobile, and the two second driving cylinders 32 can respectively drive the two second positioning and clamping mechanisms 22 to approach the B-pillars 52 of the two side panel assemblies 5 arranged at intervals, so that the two second positioning and clamping mechanisms 22 respectively position and clamp the B-pillars 52 of the two side panel assemblies 5, thereby positioning and clamping the B-pillars 52 of the side panel assemblies 5 from the interior of the automobile; after the overall assembly of the automobile is completed, the two first driving cylinders 31 can respectively drive the two second positioning and clamping mechanisms 22 away from the B-pillars 52 of the two side panel assemblies 5, so that the two second positioning and clamping mechanisms 22 are retracted into the second mounting frame 12.

That is, during the overall assembly of the automobile, the second driving cylinder 32 drives the second sliding frame 221 to drive the second positioning block 222, the second clamping cylinder 223 and the second clamping arm 224 to approach the B-pillar 52, so that the second positioning pin 225 on the second clamping arm 224 is inserted into the positioning hole of the B-pillar 52, and the second positioning block 222 abuts against one side surface of the B-pillar 52, and the second clamping cylinder 223 drives the second clamping arm 224 to drive the second abutting block 226 to abut against the other side surface of the B-pillar 52, so that the second abutting block 226 and the second positioning pin 225 are inserted into the positioning hole of the B-pillar 52, and the second positioning block 222 abuts against the other side surface of the B-pillar 52.

At the same time, the two ends of the third mounting frame 13 are respectively provided with third slide rails 247 that are slidably matched with the third sliding frame 23, and the third driving cylinder 33 can drive the third sliding frame 23 to move along the third slide rails 247, so as to ensure the stability of the movement of the third sliding frame 23.

[0048] Further, please refer again to Figure 1 , Figure 2 and Figure 6The third positioning and clamping mechanism 24 includes a third positioning pin 241, a third positioning block 242 and two clamping assemblies 243 arranged on the third sliding frame 23; the third positioning pin 241 is used to cooperate with the positioning hole of the tailgate frame, the third positioning block 242 is used to abut against the tailgate frame, and the two clamping assemblies 243 are used to clamp the upper edge and the rear edge of the D-pillar 54 respectively; the clamping assembly 243 includes a third clamping cylinder 244 and two third clamping arms 245 arranged on the third sliding frame 23, the two third clamping arms 245 are arranged relatively spaced, one end of the two third clamping arms 245 is respectively connected to the third clamping cylinder 244, and the other ends of the two third clamping arms 245 are respectively arranged with third abutting blocks 246; the third clamping cylinder 244 is used to drive the two third clamping arms 245 to drive the two third abutting blocks 246 to approach each other, so that the two third abutting blocks 246 cooperate to clamp the D-pillar 54. In the present invention, two third clamping arms 245 are respectively movably hinged with the third sliding frame 23. At the same time, the cylinder body of the third clamping cylinder 244 is movably arranged, wherein one third clamping arm 245 is connected to the cylinder body of the third clamping cylinder 244, and the other third clamping arm 245 is connected to the output shaft of the third clamping cylinder 244. That is, during the overall assembly of the automobile, the third driving cylinder 33 drives the third sliding frame 23 to drive the third positioning pin 241, the third positioning block 242 and the two clamping assemblies 243 to approach the D-pillar 54 and the tailgate frame, the third positioning pin 241 is inserted into the positioning hole of the tailgate frame, the third positioning block 242 abuts against one side surface of the tailgate frame, and the tailgate frame is pressed against the D-pillar 54, and the two clamping assemblies 243 clamp the upper edge and the rear edge of the D-pillar 54 respectively, thereby ensuring that the D-pillar 54 and the tailgate frame are assembled in the overall assembly of the automobile. Assembly stability during the assembly process; after the overall assembly of the automobile is completed, the third clamping cylinder 244 in the clamping assembly 243 first drives the two third clamping arms 245 to drive the two third abutment blocks 246 to move away from each other to loosen the D-pillar 54, and then the third driving cylinder 33 drives the third sliding frame 23 to drive the third positioning pin 241, the third positioning block 242 and the two clamping assemblies 243 away from the D-pillar 54 and the tailgate frame, so that the tailgate frame can be freed from the restrictions of the third positioning pin 241 and the third positioning block 242.

[0049] It should be particularly noted in the present invention that the third mounting frame 13 is placed on the outside of the car facing the tailgate hole of the car and does not extend into the interior of the car, but the third mounting frame 13 is between the two side panel assemblies 5, and the third driving cylinder 33 can drive the third sliding frame 23 to move toward the direction close to the tailgate hole, so that the third positioning and clamping mechanism 24 can partially extend into the interior of the car and clamp the D-pillar 54 of the side panel assembly 5.

[0050] In one embodiment, see Figure 1 , Figure 2 and Figure 7The mounting frame group 19 further includes two fourth mounting frames 14 respectively arranged on both sides of the mounting crossbeam 18, and the fourth mounting frames 14 include a base 141 arranged on the main frame 1, and a mounting plate 142 movably hinged to the base 141; the driving device 3 further includes a fourth driving cylinder 34, the cylinder body of the fourth driving cylinder 34 is arranged on the mounting plate 142 of one of the fourth mounting frames 14, and the output shaft of the fourth driving cylinder 34 is connected to the mounting plate 142 of the other fourth mounting frame 14; the first positioning and clamping device 2 further includes two fourth positioning and clamping mechanisms 25 respectively arranged on the two mounting plates 142; the fourth driving cylinder 34 is used to drive the two fourth positioning and clamping mechanisms 25 to approach the upper side beams 55 of the two side enclosure assemblies 5 arranged at intervals, so that the two fourth positioning and clamping mechanisms 25 respectively clamp the two upper side beams 55. At the same time, the fourth driving cylinder 34 can also drive the two fourth positioning and clamping mechanisms 25 away from the upper side beams 55. That is, during the overall assembly of the automobile, the mounting crossbeam 18 can be placed on the top of the automobile, and the two fourth mounting brackets 14 can extend into the interior of the automobile. The output shaft of the fourth driving cylinder 34 continues to extend outward to drive the mounting plate 142 connected thereto to drive the fourth positioning clamping mechanism 25 to approach the upper side beam 55 on one side. Since the force is mutual, the mounting plate 142 connected to the cylinder body of the fourth driving cylinder 34 can also drive the fourth positioning clamping mechanism 25 to approach the upper side beam 55 on the other side, thereby realizing the side enclosure assembly 5 from the interior of the automobile. After the automobile is assembled, the output shaft of the fourth drive cylinder 34 is retracted into the cylinder body to drive the mounting plate 142 connected thereto to drive the fourth positioning clamping mechanism 25 away from the upper side beam 55 on one side. At the same time, since the mounting plate 142 connected to the cylinder body of the fourth drive cylinder 34 is hinged with the base 141 and the supporting function of the fourth drive cylinder 34 is lost, the mounting plate 142 connected to the cylinder body of the fourth drive cylinder 34 can also drive the fourth positioning clamping mechanism 25 away from the upper side beam 55 on the other side. In addition, multiple groups of fourth mounting frames 14 can be arranged at intervals on the mounting crossbeam 18.

At the same time, the fourth clamping cylinder 253 can also drive the two fourth clamping arms 252 to drive the two fourth abutting blocks 254 to move in a direction away from the corresponding fourth positioning block 251 to loosen the upper side beam 55. In the present invention, the cylinder body of the fourth clamping cylinder 253 is movably arranged, one fourth clamping arm 252 is connected to the cylinder body of the fourth clamping cylinder 253, and the other fourth clamping arm 252 is connected to the output shaft of the fourth clamping cylinder 253, that is, when the output shaft of the fourth clamping cylinder 253 continues to extend, the cylinder body of the fourth clamping cylinder 253 moves in a direction away from the extension direction of the output shaft of the fourth clamping cylinder 253, so that the fourth abutment block 254 on the fourth clamping arm 252 connected to the output shaft of the fourth clamping cylinder 253 is close to the corresponding fourth mounting block to clamp the upper side beam 5 5, the fourth abutment block 254 on the fourth clamping arm 252 connected to the cylinder body of the fourth clamping cylinder 253 can also be close to the corresponding fourth mounting block to clamp the upper edge of the upper side beam 55; when the output shaft of the fourth clamping cylinder 253 moves toward the cylinder body and retracts, the movement direction of the cylinder body of the fourth clamping cylinder 253 is consistent with the extension direction of the output shaft of the fourth clamping cylinder 253, so that the fourth abutment blocks 254 of the two fourth clamping arms 252 move respectively in the direction away from the corresponding fourth positioning blocks 251, thereby loosening the upper and lower edges of the upper side beam 55.
