DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides an integrated hood and fender tooling, which can solve the problem of integrating the hood and fender assembly into a set of tooling, which has a large tooling size, a large number of positioning units, long operating hours, and a small shared transformation space.

[0032] See also Figures 1 to 9As shown, the embodiment of the present application provides a hood and fender integrated tooling, including a fender positioning frame body 1, a hood positioning frame body 6 and a connecting member 10. Among them, the fender positioning frame body 1 is set in a rectangular shape, and is provided with a positioning connection mechanism 2, a positioning centering mechanism 3 and a clamping mechanism 4. When assembling the fender 51 and the hood 53, the present application first pre-installs the fender 51 on the vehicle body 50, and then adds a fender positioning frame body 1 to assemble and position it on the vehicle body 50. After that, the positioning connection mechanism 2 can be used to position and connect the fender positioning frame body 1 with the vehicle body 50, and the positioning centering mechanism 3 is used to position and align the front end of the fender 51 with the door 52 to ensure the relative posture between the fender 51 and the vehicle body 50. Finally, the clamping mechanism 4 is used to fix the fender positioning frame body 1 on the vehicle body 50 to avoid shaking and offset of the fender positioning frame body 1 during subsequent operations.

[0033] After the connection between the fender positioning frame body 1 and the vehicle body 50 is completed, the present application connects the fender positioning frame body 1 and the hood positioning frame body 6 by setting a connector 10, so that the fender positioning frame body 1 and the hood positioning frame body 6 are connected as one body. The connector 10 is set as a connecting pin, which is fixed to the fender positioning frame body 1, and a connecting hole is provided on the hood positioning frame body 6, and the connecting pin is inserted into the connecting hole. Since the hood positioning frame body 6 is provided with a positioning and fixing mechanism 7, a clamping mechanism 8 and a supporting mechanism 9, after the connection between the fender positioning frame body 1 is completed, the positioning and fixing mechanism 7 is used to fix the rear end part of the fender 51 to the vehicle body 50 to ensure the relative position relationship between the fender 51 and the vehicle body 50. Since the overall volume of the fender 51 is relatively large, and there is a mounting point for the headlight on the fender 51, in order to further ensure the positioning accuracy of the fender 51, the provided pressing mechanism 8 is used to press and fix the lampshade mounting part at the rear end of the fender 51 with the hood positioning frame body 6, so that each mounting positioning point of the fender 51 is aligned with the vehicle body 50. After the positioning of the fender 51 and the vehicle body 50 is completed, it is also necessary to install and position the hood 53, so the provided supporting mechanism 9 is used to support and position the hood 53 so that the hood 53 is aligned with the vehicle body 50. At this time, the positioning and mounting points of the fender 51 and the hood 53 on the vehicle body 50 have been determined, and the connection of each positioning and mounting point can be completed in sequence later. The overall operation is convenient, the number of positioning units is small, the operation efficiency is high, and the fender positioning frame body 1 and the hood positioning frame body 6 have simple and reliable structures, occupy a small space, and the assembly of the fender 51 and the hood 53 can be completed at one processing station.

[0034] In the present application, the positioning connection mechanism 2 includes a positioning column 20 and a positioning connection pin 21. The positioning column 20 is vertically connected to the bottom of the fender positioning frame body 1. When in use, the positioning column 20 is placed on the vehicle body 50 so that the fender positioning frame body 1 is horizontally placed on the vehicle body 50. At this time, the fender 51 positioning frame is well positioned in the Z direction. In addition, in order to avoid scratches between the positioning column 20 and the vehicle body 50, an anti-wear wheel 200 is provided at the bottom of the positioning column 20. The anti-wear wheel 200 is smoothly arranged, which can effectively prevent the positioning column 20 from rubbing on the vehicle body 50 and damaging the vehicle body 50, and the structure is reliable. Then, a first bracket 22 is provided on the fender positioning frame body 1, and the first bracket 22 is located at the bottom of one side of the fender positioning frame body 1. Then, a positioning connecting pin 21 is passed through the first bracket 22. When in use, the positioning connecting pin 21 is inserted into the mounting hole on the vehicle body 50 for fixing with the vehicle body 50, thereby ensuring that the fender positioning frame body 1X is aligned upward with the vehicle body 50. At this time, the vehicle body 50 is also used as a reference to position the fender positioning frame body 1, and then the positioning and centering mechanism 3 is used to position and align the front end part of the fender 51 with the door 52.

[0035] In the present application, the positioning and centering mechanism 3 includes a second bracket 30, a gap positioning pin 31, a first clamping block 32, a second clamping block 33 and a driving assembly; the second bracket 30 is movably connected to the two ends of the fender positioning frame body 1, and the movement method includes but is not limited to providing slide rails 300 at the top two ends of the fender positioning frame body 1, the second bracket 30 is arranged at a right angle, and a slider 301 cooperating with the slide rail 300 is provided at the bottom of the second bracket 30; the gap positioning pin 31 is provided on the second bracket 30, and the gap positioning pin 31 is provided in a flat pin. When in use, the gap is inserted into the assembly gap between the fender 51 and the door 52 to ensure the gap surface difference between the door 52 and the fender 51; the first clamping block 32 is connected to the second bracket 3 0, and is located on one side of the gap positioning pin 31, the first clamping block 32 is used to abut against the vehicle door 52; the second clamping block 33 is connected to the second bracket 30 and is located on the other side of the gap positioning pin 31, the second clamping block 33 is used to abut against the fender 51, and the first clamping block 32 and the second clamping block 33 are abutted against the fender 51. The side is set as an inclined surface for matching the fender 51 and the door 52 surface; finally, the set driving assembly is connected to the fender positioning frame body 1, and the driving member is used to drive the second brackets 30 at both ends to move relative to each other, so that the first clamping block 32 abuts against the vehicle door 52, and the second clamping block 33 abuts against the fender 51, thereby ensuring the assembly surface difference between the fender 51 and the door 52, and ensuring that the fender 51 meets high-precision assembly.

[0036] In the present application, the driving assembly provided includes a rotating column 34, a first connecting rod 35 and a second connecting rod 37. The rotating column 34 is installed on the fender positioning frame body 1. The rotating column 34 is also rotatably connected to a rotating plate 340, and the rotating plate 340 is arranged in a diamond shape; the first connecting rod 35 is hinged to one end of the rotating plate 340, and one end of the first connecting rod 35 is hinged to one of the second brackets 30, and the other end is connected to a pulling handle 36, and the pulling handle 36 is fixedly installed on the fender positioning frame body 1; one end of the second connecting rod 37 is hinged to one end of the rotating plate 340 away from the first connecting rod 35, and the other end is hinged to a second bracket 30 close to the pulling handle 36. The first connecting rod 35, the rotating plate 340 and the second connecting rod 37 effectively form a connecting rod linkage structure. By operating the pulling handle 36, the first connecting rod 35 is driven to move. At this time, one of the second brackets 30 also moves relatively. At this time, under the action of the rotating plate 340, the second connecting rod 37 is also relatively displaced, and the moving direction is opposite to the first connecting rod 35, that is, the other second bracket 30 is relatively displaced close to the first bracket 22. At this time, the first clamping block 32 abuts on the vehicle door 52, and the second clamping block 33 abuts on the fender 51, ensuring the assembly surface difference between the vehicle door 52 and the fender 51, and the fenders 51 on the left and right sides of the vehicle body 50 are synchronously clamped and positioned under the synchronous displacement of the first bracket 22 and the second bracket 30, with a reliable structure and convenient operation.

[0037] In the present application, after the positioning of the fender 51 and the vehicle door 52 is completed, the front end of the fender 51 and the vehicle body 50 are effectively positioned, and then the fender 51 is prevented from shaking. Therefore, in the present application, the clamping mechanism 4 is provided including a third bracket 40, a clamping hook 42 and a rotating handle 43. The third bracket 40 is located at the rear side of the second bracket 30 and is installed at the bottom of the fender positioning frame body 1. A through hole is provided on the third bracket 40, and a limiting rod 41 is horizontally connected to the inner wall of the through hole; the clamping hook 42 is provided in an L shape, and then a limiting connecting groove 420 is provided on its vertical section 4200. The clamping hook 42 is passed through the through hole, and the limiting rod 41 is located within the limiting connecting groove 420 line. The limiting connecting groove 420 provided in addition includes a vertical section 4200 and a bending section 4201. The bending section 4201 is located above the vertical section 4200, and the limiting rod 41 moves in the vertical section 4200 and the bending section 4201; the rotating handle 43 is connected to the clamping hook 42 and is used to pull the clamping hook 42 up and down.

[0038] During the operation, the relative position relationship between the fender positioning frame body 1 and the vehicle body 50 is positioned, and then the rotating handle 43 is operated to pull the clamping hook 42 to move upward. At this time, as the clamping hook 42 moves, the limiting rod 41 moves from the vertical section 4200 of the limiting connecting groove 420 to the bending section 4201. At this time, the bottom horizontal section of the clamping hook 42 clamps the fender positioning frame body 1 and the vehicle body 50 together, and the limiting rod 41 is located in the bending section 4201 and cannot continue to move, thereby effectively restricting the clamping hook 42, thereby achieving the fixation of the fender positioning frame body 1 and the vehicle body 50 by the clamping hook 42, thereby avoiding shaking and offset of the fender positioning frame body 1 during subsequent operations.

[0039] In the present application, after the front end of the fender 51 is fixed to the vehicle body 50, the relative positioning point between the fender 51 and the hood 53 needs to be positioned. Therefore, the rear end of the fender 51 is further fixed to the vehicle body 50 through the positioning and fixing mechanism 7. The positioning and fixing mechanism 7 includes a fourth bracket 70 fixing round pin 71. The fourth bracket 70 is connected to the side of the hood positioning frame body 6. The fixing round pin 71 is inserted on the fourth bracket 70, and the fixing round pin 71 moves up and down along the fourth bracket 70. When in use, the fixing round pin 71 is inserted into the flange hole at the rear end of the fender 51, thereby effectively positioning the rear end of the fender 51. Since the fixing round pin 71 is mainly moved up and down along the fourth bracket 70 by pulling the fixing round pin 71 when in use, it is necessary to avoid the fixing round pin 71 interfering with the pre-installation of the fender 51 and the vehicle body 50 before the fixing round pin 71 is used. Therefore, a convex rod 710 is connected to the fixed round pin 71, and a movable groove 711 is provided on the fourth bracket 70. A limiting groove 712 is provided on the inner wall of the movable groove 711. The limiting groove 712 is perpendicular to the movable groove 711. When the fixed round pin 71 moves up and down, the convex rod 710 moves along the movable groove 711. The movement method is to directly pull the fixed round pin 71, and then rotate the fixed round pin 71 to make the convex rod 710 rotate into the limiting groove 712. At this time, the fixed round pin 71 is effectively limited. When the fixed pin is needed, the limit on the fixed round pin 71 is released and the fixed round pin 71 is put down. It is convenient to use.

[0040] In the present application, the fender 51 is provided with a plurality of flanged holes, and there may be errors between the plurality of flanged holes. In order to adapt to such errors and avoid the rotational deviation of the fixed round pin 71 after being inserted into the flanged hole, the positioning and fixing mechanism 7 provided also includes a fifth bracket 72 and an auxiliary flat pin 73. The fifth bracket 72 is connected to the hood positioning frame body 6 near the fourth bracket 70; the auxiliary flat pin 73 is penetrated on the fifth bracket 72, and a protruding rod 710 is also provided on the auxiliary flat pin 73. The structure of the fifth bracket 72 is the same as that of the fourth bracket 70, that is, the auxiliary flat pin 73 can also be limited and fixed on the fifth bracket 72. When in use, the auxiliary flat pin 73 is used to be inserted into the flanged hole at the rear end of the fender 51. Therefore, the auxiliary flat pin 73 is flatly arranged, so that the auxiliary flat pin 73 can be well inserted into the flanged hole, effectively adapting to the error of the flanged hole, and the flat arrangement of the auxiliary flat pin 73 can avoid the rotational deviation, thereby ensuring the stability of the positioning of the fender 51 and a reliable structure.

[0041] In the present application, in order to further ensure the assembly stability of the fender 51 and improve its assembly accuracy, the clamping mechanism 8 is provided, including a sixth bracket 80, a third clamping block 81 and a clamping clamp 82. The sixth bracket 80 is connected to the hood positioning frame body 6; the third clamping block 81 is connected to the inner side of the sixth bracket 80, and the third clamping block 81 is arranged on a side close to the fender 51 as an inclined surface for adapting to the panel of the fender 51, and the third clamping block 81 is used to abut against the lampshade mounting part at the rear end of the fender 51; the clamping clamp 82 is connected to the bottom of the hood positioning frame body 6, and the clamping clamp 82 includes a pressure rod and a hinged handle. The hinged handle is connected to the sixth bracket 80, the pressure rod is fixedly connected to the hinged handle, and the clamping clamp 82 rotates close to the third pressure block 81. When in use, the pressure rod cooperates with the third clamping block 81 to clamp the fender 51 between the third clamping block 81 and the clamping clamp 82, thereby ensuring that the fender 51 is positioned and fixed as a whole, and the structure is reliable.

[0042] In the present application, after completing the positioning of the fender 51, the hood 53 is also positioned by the set support mechanism 9, and the set support mechanism 9 includes a first support module 90, a second support block and a positioning pin 92. The first support module 90 is connected to the top of the hood positioning frame body 6 and is used to support the front end of the hood 53; the second support module 91 is connected to one side of the second support module 91, and is used to support the rear end of the hood 53. The positioning pin 92 is connected to the hood positioning frame body 6, and when in use, the positioning pin 92 is connected to the positioning hole on the hood 53 to directly fix the position of the hood 53. In addition, under the action of the first support module 90 and the second support module 91, the structure of the hood 53 is stable. At this time, the edges of the hood 53 are aligned with the edges of the fender 51, and the positioning is reliable.

[0043] In the present application, because the fixing round pin 71 is directly inserted into the flange hole of the fender 51, in order to further ensure that the edge of the flange of the fender 51 is aligned with the edge of the hood 53, the positioning fixing mechanism also includes a flange positioning block 74, which is connected to the positioning frame of the hood 53. The flange positioning block 74 is L-shaped. When in use, the flange positioning block 74 is used to abut against the flange edge of the fender 51 to ensure the positioning accuracy of the fender 51. The structure is simple and reliable.

[0044] The implementation principle of the embodiment of the present application is: by pre-installing the fender 51 and the vehicle door 52, and then connecting the fender positioning frame body 1 to the vehicle body 50, and positioning and aligning the front end part of the fender 51 with the vehicle door 52 through the positioning and centering mechanism 3, so as to ensure that the installation posture of the fender 51 is aligned with the vehicle body 50 as a reference, and finally using the clamping mechanism 4 to fix the fender 51 positioning frame on the vehicle body 50, to ensure that the fender 51 positioning frame structure is stable during the subsequent installation process, and to ensure the assembly accuracy of the fender 51. Then, the hood positioning frame body 6 and the fender positioning frame body 1 are connected through the connecting member 10, and the rear end part of the fender 51 is further fixed to the vehicle body 50 through the positioning and fixing mechanism 7. In addition, the lampshade mounting part at the rear end of the fender 51 is clamped and fixed by the pressing mechanism 8 to ensure that the positioning point of the fender 51 as a whole is fixed on the vehicle body 50, so as to accurately install the fender 51 on the vehicle body 50. Finally, the hood 53 is placed on the supporting mechanism 9, so as to align the hood 53 with the vehicle body 50, ensure that the mounting surface of the hood 53 is aligned with the mounting surface of the vehicle body 50, and then the hood 53 is connected to the vehicle body 50 through a hinge. After the assembly of the fender 51 and the hood 53 is completed, the connection between the fender positioning frame body 1 and the hood positioning frame body 6 is released, and the fender positioning frame body 1 and the hood positioning frame body 6 can be taken out.
