Description

Technical Field

[0001] The present application relates to the technical field of automobile assembly, and particularly relates to an assembly tooling for an automobile front-end module. Background Art

[0002] At present, in the intelligent manufacturing process of new energy vehicles, multiple components in the automobile front-end module are respectively assembled to the vehicle body on the general assembly line. This requires the development of relatively large front-end module positioning fixtures, etc. to meet the design requirements of adjustable front-end modules. However, the positioning points of the front-end module assembled on the vehicle body are often restricted by the vehicle body structure and the previous positioning strategy, and it is difficult to achieve the expected effect after using the front-end module positioning fixture, resulting in a certain impact on the project cycle and development cost.

[0003] In the related art, the front-end module positioning fixture on the automobile general assembly line usually adopts an integral manual front-end module fixture or a robotic arm front-end module fixture. Among them, the volume of both fixtures is generally large, and restricted by structures such as the engine compartment, the ergonomics of the fixture is poor, and multiple operators are required. In addition, when picking up and placing the fixture, the fixture is prone to collide with the vehicle body and general assembly parts, resulting in paint chipping or part scratching, and subsequent repair is required, thus greatly increasing the assembly cost of each component of the automobile front-end module. Summary of the Utility Model

[0032] Currently, in the intelligent manufacturing process of new energy vehicles, multiple components in the vehicle front-end module are assembled to the vehicle body separately on the final assembly line. This requires the development of relatively large front-end module positioning fixtures, etc. to meet the design requirements of adjustable front-end modules. However, the positioning points of the front-end module assembled on the vehicle body are often restricted by the vehicle body structure and the previous positioning strategy, and it is difficult to achieve the expected effect after using the front-end module positioning fixture, resulting in a certain impact on the project cycle and development cost.

[0033] In the related art, the front-end module positioning fixtures on the vehicle final assembly line usually adopt integral manual front-end module fixtures or robotic arm front-end module fixtures. Among them, the volumes of both fixtures are generally large, and due to the restrictions of structures such as the engine compartment, the ergonomics of the fixtures are poor, and multiple operators are required. In addition, when picking up and placing the fixtures, the fixtures are prone to collide with the vehicle body and final assembly parts, resulting in paint chipping or part scratching, and subsequent repair is required, thus greatly increasing the assembly cost of each component of the vehicle front-end module.

[0034] Please refer to Figures 1-8, to solve the problems of low assembly efficiency and high cost in the assembly process of the existing automotive front-end module, the present application provides an automotive front-end module assembly tooling 100, which is used for assembling the automotive front-end module 500. Among them, as Figure 2 shown, the automotive front-end module 500 includes a front bumper beam 510, a hood lock cross beam 520, and a headlight bracket 530. The front bumper beam 510 includes a main cross beam 511, a connecting longitudinal beam 512, and an energy absorption box 513. The energy absorption box 513 and the connecting longitudinal beam 512 are both connected to the main cross beam 511. An installation plate 514 is provided at one end of the energy absorption box 513 away from the main cross beam 511, and the front bumper beam 510 is installed on the vehicle body through the installation plate 514. Further, a connecting bracket 521 is provided on the hood lock cross beam 520, and the hood lock cross beam 520 is sleeved and connected to one end of the connecting longitudinal beam 512 away from the main cross beam 511 through the connecting bracket 521. The headlight bracket 530 is connected to the side of the connecting longitudinal beam 512. Here, the hood lock cross beam 520 and the connecting bracket 521, the connecting bracket 521 and the connecting longitudinal beam 512, and the headlight bracket 530 and the connecting longitudinal beam 512 are all locked and matched through fasteners.

[0035] Please continue to refer to Figures 1-8 , the automotive front-end module assembly tooling 100 provided by the present application includes a workbench 10, a first clamping unit 20, a second clamping unit 30, and a third clamping unit 40. The first clamping unit 20, the second clamping unit 30, and the third clamping unit 40 are all installed on the workbench 10. The first clamping unit 20 includes a first positioning component 21 and a first clamping component 22. The first positioning component 21 is used to position the installation plate 514, and the first clamping component 22 is used to clamp the installation plate 514; the second clamping unit 30 includes a second positioning component 31 and a second clamping component 32. The second positioning component 31 is used to position the hood lock cross beam 520, and the second clamping component 32 is used to clamp the hood lock cross beam 520; the third clamping unit 40 includes a third positioning component 41 and a third clamping component 42. The third positioning component 41 is used to position the headlight bracket 530, and the second clamping component 32 is used to clamp the headlight bracket 530.

[0036] It can be understood that by integrating multiple structures on a tooling, the present application can achieve the positioning between the front bumper beam 510, the hood lock cross member 520, and the headlight bracket 530 in the vehicle front-end module 500, thereby easily determining the positional relationship among the three, improving the matching accuracy of the three, and effectively avoiding the assembly influence of the vehicle body structure on the front-end module 500 compared with the assembly method on the traditional general assembly line, thus reducing the tolerance accumulation of the front-end module 500 caused by the vehicle body. Moreover, moving the front-end module 500 to off-line assembly can reduce the operation difficulty of the operator, and only one operator is required to complete the assembly, reducing the labor intensity and effectively saving the labor cost. At the same time, it also reduces the skill requirements of the operator, improves the work efficiency, and reduces the probability of paint damage caused by improper operation, avoiding subsequent rework, thereby further reducing the cost.

[0037] It should be noted that the hood lock cross member 520 is used to install the hood, the headlight bracket 530 is used to install the headlight, and a decorative panel can be installed on the front bumper beam 510. Taking the installation of the hood and the decorative panel on the front-end module 500 as an example, since the front-end module 500 of the present application avoids the tolerance accumulation caused by the vehicle body, the assembly accuracy between the hood and the decorative panel is relatively high, and the gap between the two can meet the design requirements, thereby realizing the air intake requirement of the hood part and preventing the functional problem of "whistling" of the hood caused by a small gap between the hood and the decorative panel.

[0038] Further, in an embodiment, as Figure 1 shown, driving wheels 11 are provided at the bottom of the workbench 10, and the movement adjustment of the vehicle front-end module assembly tooling 100 can be realized by using the driving wheels 11, greatly improving the convenience.

[0039] In an embodiment, as Figure 3 and Figure 4 shown, the first positioning component 21 includes a first base 211, a first movable member 212, and a first positioning member 213. The first base 211 is installed on the workbench 10, the first movable member 212 is movably connected to the first base 211, and the first positioning member 213 is connected to the first movable member 212 and can move under the drive of the first movable member 212. Among them, the first positioning member 213 is used to position the mounting plate 514. In this way, the first positioning member 213 can adjust its own position according to the design requirements, which is beneficial to determining the relative position between the mounting plate 514 and the front bumper beam 510 and improving the mounting accuracy.

[0040] Among them, the first positioning member 213 can be configured as a positioning pin to cooperate with the hole structure on the mounting plate 514 for positioning.

[0041] Further, in an embodiment, as Figure 4As shown, the first movable member 212 includes a first movable block 2121 and a second movable block 2122. The first movable block 2121 is movably connected to the first base 211, and the second movable block 2122 is movably connected to the first movable block 2121. Among them, one of the first movable block 2121 and the second movable block 2122 moves in the X direction, and the other moves in the Y direction. The first positioning member 213 is connected to the second movable block 2122. In this way, the adjustment function of the first positioning member 213 in the X direction and the Y direction is realized through the first movable block 2121 and the second movable block 2122. Here, the mounting plate 514 abuts against the second movable block 2122 in the Z direction to ensure the reliability of the position of the mounting plate 514 relative to the workbench 10.

[0042] It should be noted that the X direction, the Y direction, and the Z direction respectively correspond to three three-dimensional directions of the workbench 10. For example, in this embodiment, as Figure 1 shown, the X direction is defined as the width direction of the workbench 10, the Y direction is defined as the length direction of the workbench 10, and the Z direction is defined as the height direction of the workbench 10. However, the X direction, the Y direction, and the Z direction of the present application are not limited to the representation forms in the embodiment.

[0043] In one embodiment, as Figure 1 and Figure 5 shown, the first clamping assembly 22 includes a first positioning block 221, a first clamping member 222, and a first driving member 223. The first positioning block 221 and the first driving member 223 are respectively connected to opposite side surfaces of the workbench 10. That is, the first driving member 223 is installed on the back surface of the tabletop of the workbench 10 to reduce the occupation of the space at the tabletop and facilitate installation.

[0044] Furthermore, the output end of the first driving member 223 penetrates through the workbench 10 and is connected to the first clamping member 222, and is used to drive the first clamping member 222 to move towards the first positioning block 221 to cooperate with the first positioning block 221 to clamp the mounting plate 514. Among them, the end surface of the first positioning block 221 away from the workbench 10 is flush with the end surface of the second movable block 2122 away from the workbench 10. In this way, when the mounting plate 514 is placed on the second movable block 2122 and the first positioning block 221, the mounting plate 514 can be placed horizontally. At the same time, by operating the first clamping member 222 to clamp the mounting plate 514 through the first driving member 223, the position reliability of the front anti-collision beam 510 during the assembly process can be improved, preventing deviation, thereby greatly improving the assembly efficiency of the front end module 500.

[0045] In one embodiment, as Figure 6 and Figure 8As shown, the second clamping unit 30 further includes a second base 33, a third movable block 34, a support frame 35, a first pushing member 36, and a mounting rod 37. The second base 33 is connected to the workbench 10. The support frame 35 is movably connected to the second base 33 along the Y direction and the Z direction through the third movable block 34. The first pushing member 36 is mounted on the support frame 35, and the output end of the first pushing member 36 is connected to the mounting rod 37 for driving the mounting rod 37 to move along the X direction. Among them, the second positioning assembly 31 and the second clamping assembly 32 are both mounted on the mounting rod 37, and a limiting support block 371 for placing the hood lock cross beam 520 is connected to the mounting rod 37. In this way, the position adjustment of the second positioning assembly 31 along the X direction, the Y direction, and the Z direction can be realized, so that when the second positioning assembly 31 is in positioning cooperation with the hood lock cross beam 520, the relative position of the hood lock cross beam 520 can be better determined according to the design requirements, and the installation and matching accuracy of the hood lock cross beam 520 can be improved.

[0046] Specifically, in an embodiment, the second positioning assembly 31 includes a positioning post 311 and a second positioning member 312. The second positioning member 312 is connected to the mounting rod 37 through the positioning post 311. Among them, the second positioning member 312 is used for positioning the hood lock cross beam 520. In this way, it is convenient to achieve the positioning effect of the hood lock cross beam 520 and ensure the reliability of the positioning. Preferably, the second positioning member 312 can be configured as a positioning pin to cooperate with the hole structure on the hood lock cross beam 520 for positioning.

[0047] Further, in an embodiment, the second clamping assembly 32 includes a second driving member 321 and a second clamping member 322. The second driving member 321 is mounted on the mounting rod 37, and the output end of the second driving member 321 is connected to the second clamping member 322 for driving the second clamping member 322 to move towards the direction close to the mounting rod 37 to cooperate with the limiting support block 371 to clamp the hood lock cross beam 520. In this way, the locking of the hood lock cross beam 520 can be realized, and the decrease of the assembly accuracy caused by its movement can be prevented.

[0048] In an embodiment, as Figure 7 and Figure 8As shown in the figure, the third clamping unit 40 further includes a third base 43, a sliding member 44, a movable base 45, a second pusher 46, and a connecting plate 47. The third base 43 is connected to opposite ends of the sliding member 44, and both the third base 43 and the sliding member 44 are mounted on the workbench 10. The movable base 45 is mounted on the sliding member 44 and can slide along the Y direction on the sliding member 44. The second pusher 46 is mounted on the movable base 45, and the output end of the second pusher 46 is connected to the connecting plate 47 for driving the connecting plate 47 to move along the Z direction. Among them, the third positioning component 41 and the third clamping component 42 are both mounted on the connecting plate 47. In this way, the position adjustment of the third positioning component 41 along the Y direction and the Z direction can be realized, so that when the third positioning component 41 is positioned and matched with the headlight bracket 530, the relative position of the headlight bracket 530 can be better determined according to the design requirements, and the installation and matching accuracy of the headlight bracket 530 can be improved.

[0049] Specifically, to achieve the limiting effect of the third positioning component 41 on the headlight bracket 530, in one embodiment, the third positioning component 41 includes a limiting block 411 and a third positioning block 412. The third positioning block 412 is connected to the connecting plate 47. The limiting block 411 is connected to opposite side surfaces of the third positioning block 412 and encloses a limiting groove 401 with the third positioning block 412. The limiting groove 401 is used to accommodate and limit the headlight bracket 530. Here, the headlight bracket 530 is specifically L-shaped, and opposite ends of one side surface of the headlight bracket 530 are respectively abutted and limited by the two limiting blocks 411.

[0050] Further, in one embodiment, the third clamping component 42 includes a third driving member 421 and a third clamping member 422. The third driving member 421 is mounted on the connecting plate 47, and the output end of the third driving member 421 is connected to the third clamping member 422 for driving the third clamping member 422 to move toward the direction close to the connecting plate 47 to cooperate with the third positioning block 412 to clamp the headlight bracket 530. In this way, the locking of the headlight bracket 530 can be realized, and the decrease of the assembly accuracy caused by its movement can be prevented.

[0051] In one embodiment, the first driving member 223, the second driving member 321, the third driving member 421, the first pusher 36, and the second pusher 46 can all adopt driving cylinders or driving motors, etc., to reduce the driving difficulty.

[0052] To further realize the automation of driving, a button serving as a switch can also be set on the workbench 10, and each driving member or pusher can be turned on through the button, further reducing the operation difficulty of the operator.

[0053] It should also be noted that in the present application, the movement in the X direction, Y direction, and Z direction can be achieved by the cooperation of a slide rail and a slider, a chute, etc. Of course, it can also be reasonably set according to actual needs.

[0054] The assembly process of the front-end module 500 is realized by using the automotive front-end module assembly tooling 100 in the present application as follows: First, place the front bumper beam 510 on the first clamping unit 20, and position the mounting plate 514 on the front bumper beam 510 through the first positioning component 21. Then, pre-assemble the hood lock crossbeam 520 to the second clamping unit 30, and position the hood lock crossbeam 520 through the second positioning component 31. Then, pre-assemble the headlight bracket 530 to the third clamping unit 40, and position the headlight bracket 530 through the third positioning component 41. After that, press the button to control the first clamping component 22 to clamp the mounting plate 514, and control the second clamping component 32 to clamp the hood lock crossbeam 520, and control the third clamping component 42 to clamp the headlight bracket 530. Finally, use fasteners to realize the locking between the hood lock crossbeam 520 and the connecting bracket 521, between the connecting bracket 521 and the connecting longitudinal beam 512, and between the headlight bracket 530 and the connecting longitudinal beam 512. Press the button again to unlock, so that the front-end module 500 can be taken away and enter the next cycle.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
