Description

Technical Field

[0001] The present application relates to the technical field of automobile assembly, and in particular to an automobile front face assembly tool. Background Art

[0002] A car's front fenders, combination headlights (hereafter referred to as "headlights"), and hood lock crossbar are all critical exterior components, closely interdependent. Any change in any one of them can impact the overall appearance. Currently, most vehicle models utilize a method where the headlight mounting bracket is welded to the front hull using a dedicated fixture. The hull is then assembled with other structural components, such as the front and rear floors, side panels, and roof, to form a complete body-in-white (BIW). However, during the welding process, due to multiple factors, including interference between components, unstable fixture positioning, component tolerances, deformation during welding, and human error, the headlight mounting bracket often exhibits significant dimensional deviations when affixed to the BIW, resulting in poor stability. Especially after assembly of the four-door, two-hood assembly, the headlight mounting bracket struggles to maintain accurate spatial alignment with components such as the fenders and lock crossbar. This can lead to poor headlight assembly and excessive clearances and surface differences between the headlights and related components, affecting the overall vehicle aesthetics and increasing the labor costs of subsequent repairs. Therefore, precisely controlling the clearances and surface differences between these components to ensure the overall vehicle's appearance quality has become a highly challenging task.

[0033] See also Figure 1 as well as Figure 2 , Figure 1 This is a schematic diagram of the working of the automobile front face assembly tooling in some embodiments of the present application. Figure 2 Schematic diagram of the structure of the automobile front face assembly tool in some embodiments of the present application. The embodiment of the present application provides an automobile front face assembly tool, including a frame 10, a fender positioning mechanism 20, a headlight mounting mechanism 30, a lock beam mounting mechanism 40 and a tool clamping mechanism 50. Among them, the frame 10 is made of aluminum pipe, which can reduce the weight of the frame 10 while ensuring the overall structural strength of the frame 10, thereby achieving the requirements of lightweight design. The fender positioning mechanism 20 is installed at the rear end of the frame 10, and is used to fit with the fender surface and position the frame 10; the headlight mounting mechanism 30 is installed at the front end of the frame 10, and is used to install and position the headlight bracket; the lock beam mounting mechanism 40 is installed at the front end of the frame 10, and is used to install and position the lock beam; the tool clamping mechanism 50 is installed at the rear end and middle part of the frame 10, and is used to fix the frame 10 to the vehicle body; the front end, middle part and rear end of the frame 10 are arranged in sequence along the X direction.

[0034] In the present application, the frame 10 can be accurately positioned by providing a fender positioning mechanism 20, and the rear end and middle portion of the frame 10 are fixedly connected to the vehicle body by a tool clamping mechanism 50. Multiple fixations can improve the stability of the frame 10 and prevent the frame 10 from shifting during the process of fixing the headlight bracket, lock beam, and vehicle body, resulting in inaccurate connection positions. In addition, since the headlight mounting mechanism 30 and lock beam mounting mechanism 40 are provided at the front end of the frame 10, the headlight bracket and the front cover lock beam can be installed and positioned simultaneously. The fender, headlight bracket, and lock beam are directly connected by the frame 10 to ensure the coordination between the three, shorten the dimensional chain, and reduce cumulative errors. By integrating the positioning and assembly of the headlight bracket and lock beam, labor is saved, and the assembly precision of the headlight bracket and lock beam is highly consistent.

[0035] See also Figures 3 to 5 , Figure 3 yes Figure 1 The enlarged schematic diagram of point A in the middle, Figure 4 yes Figure 2 The front view of the automobile front face assembly tool in the embodiment, Figure 5 yes Figure 4 An enlarged schematic diagram of point C in the embodiment.

[0036] In some embodiments, the headlight mounting mechanism 30 includes a headlight locating pin 31 and a headlight clamping assembly 32, wherein the headlight locating pin 31 is movably mounted on the frame 10 along the X direction to limit the movement of the headlight bracket in the YZ plane; the headlight clamping assembly 32 is clamped at both ends of the headlight bracket in the X direction.

[0037] In this embodiment, the headlight locating pin 31 can be inserted through the locating hole in the headlight bracket to limit the headlight bracket in the YZ plane. The headlight clamping assembly 32 is then clamped at both ends of the headlight bracket in the X direction to limit the headlight in the X direction. After the headlight bracket is assembled with the vehicle body, the headlight clamping assembly 32 is released, and the headlight locating pin 31 is moved out of the plug-in position with the headlight bracket to remove the tooling.

[0038] See also Figure 3 Specifically, the headlight mounting mechanism 30 also includes a headlight moving assembly 33, which includes a guide rail 331, a moving member 332 and a positioning pin driving member 333. The guide rail 331 is fixedly connected to the frame 10; the moving member 332 is connected to the guide rail 331 in a sliding manner along the X direction; the positioning pin driving member 333 is used to drive the moving member 332 to move. The moving member 332 can be in the shape of a plate, a long strip or other special shapes, which is not specifically limited here.

[0039] The positioning pin driver 333 can be an automatic linear drive mechanism, such as an electric push rod or a pneumatic cylinder. Alternatively, the positioning pin driver 333 can be manually driven. For example, a screw rotatably mounted on the guide rail 331 is threadedly connected to the movable member 332, and the movable member 332 is moved along the guide rail 331 by rotating the screw. For ease of operation, a handle can be provided at the end of the screw, which can be operated to rotate the screw.

[0040] See also Figure 3 and Figure 5 In some embodiments, the headlight clamping assembly 32 includes a headlight support 321, a headlight clamping member 322 and a headlight driving member 323. One end of the headlight support 321 is fixedly connected to the moving member 332, and the other end is fixedly connected to the headlight positioning pin 31; one end of the headlight clamping member 322 is rotatably connected to the headlight support 321, and the other end and the headlight support 321 are respectively supported on two sides of the headlight bracket in opposite directions in the X direction; the headlight driving member 323 is used to drive the headlight clamping member 322 to clamp or release the headlight bracket.

[0041] It should be noted that in this embodiment, the headlight clamping assembly 32 and the headlight locating pin 31 are simultaneously connected to the movable member 332. Therefore, the headlight clamping assembly 32 and the headlight locating pin 31 can move synchronously along the X-direction with the movable member 332. To prevent interference between the headlight clamping assembly 32 and the vehicle body, the headlight clamping member 322 of the headlight clamping assembly 32 is configured to be a rotationally clamped member.

[0042] Optionally, the rotation axis of the headlight clamp 322 is parallel to the Z-direction, allowing the headlight clamp 322 to rotate the headlight bracket to the side facing away from the headlight support 321. The extension direction of the headlight clamp 322 is parallel to the Y-direction, thereby supporting the headlight support 321 on opposite sides of the headlight bracket in the X-direction. The extension direction of the headlight clamp 322 can also be rotated to be parallel to the X-direction, thereby preventing the headlight clamp 322 from interfering with the assembled headlight bracket during movement along the X-direction with the movable member 332. In some scenarios, the headlight clamp 322 can specifically utilize the CH-13005 series clamp produced by Clamptek.

[0043] Optionally, the headlight support 321 is fixedly connected to the movable member 332, the headlight locating pin 31 is fixed to the headlight support 321, and the headlight clamping member 322 can be configured to be rotatable about an axis in the X-direction and movably connected to the headlight support 321 along the X-direction. For example, the headlight driver 323 is a linear drive mechanism, which is mounted on the headlight support 321. The headlight clamping member 322 is rotatably connected to the movable end of the headlight driver 323. When the headlight bracket needs to be clamped, the headlight clamping member 322 is rotated to face the surface of the headlight bracket. When the tool needs to be removed, the headlight clamping member 322 is rotated to separate from the surface of the headlight bracket. This prevents the headlight clamping member 322 from interfering with the assembled headlight bracket during the process of moving along the X-direction with the movable member 332.

[0044] In other embodiments, the headlight clamping assembly 32 is not connected to the movable member 332 , the headlight clamping assembly 32 is connected to the frame 10 and is fixed in the X-direction relative to the frame 10 , and the headlight locating pin 31 is fixedly connected to the movable member 332 .

[0045] See also Figure 2 and Figure 4 In some embodiments, the fender positioning mechanism 20 includes a fender positioning pin 21, which is inserted into a positioning hole on the fender along the Z direction to limit the movement of the frame 10 in the XY plane.

[0046] See also Figure 6 and Figure 7 , Figure 6 yes Figure 2 The enlarged schematic diagram of point B in the middle is shown in Figure 2. Figure 7 yes Figure 2 A side view of the vehicle front face assembly tooling in an embodiment. The tooling clamping mechanism 50 includes a rear end clamping assembly 51, mounted at the rear end of the frame 10. The rear end clamping assembly 51 comprises a rear end support 511, a rear end clamping member 512, and a rear end driver 513. The rear end support 511 is fixed to the rear end of the frame 10; the rear end clamping member 512 is movably connected to the frame 10 along the Z direction, and the rear end clamping member 512 and the rear end support 511 are respectively supported on opposite sides of the vehicle body in the Z direction; the rear end driver 513 is used to drive the rear end clamping member 512 to move.

[0047] See also Figure 6, the rear end support member 511 can be made of hard nylon material to avoid scratching the car body. The rear end support member 511 is arranged at the rear end of the frame 10 and fits with the upper surface of the fender, and the rear end clamping member 512 is tightly attached to the car body sheet metal from bottom to top, thereby preventing the rear end of the frame 10 from tilting. The rear end drive member 513 can be an automatic linear drive mechanism, such as an electric push rod, a cylinder, etc. The rear end drive member 513 can also be manually driven. For example, the rear end drive member 513 includes a screw, which is rotatably connected to the frame 10. The extension direction of the screw is parallel to the Z direction. The screw is threadedly connected to the rear end clamping member 512, and the rear end clamping member 512 is moved along the Z direction by rotating the screw. In order to facilitate operation, a handle can be provided at the end of the screw, and the screw is driven to rotate by operating the handle.

[0048] See also Figure 7 In some embodiments, the tooling clamping mechanism 50 further includes a central clamping assembly 52, which is mounted in the middle of the frame 10. The central clamping assembly 52 includes a central support member 521, a central clamping member 522, and a central drive member 523. The central support member 521 is fixed to the middle of the frame 10; the central clamping member 522 is movably connected to the frame 10 along the Z direction, and the central clamping member 522 and the central support member 521 are respectively supported on opposite sides of the vehicle body in the Z direction; the central drive member 523 is used to drive the central clamping member 522 to move.

[0049] The middle support member 521 can be made of hard nylon to avoid scratching the vehicle body. The middle support member 521 is located in the middle of the frame 10 and fits against the upper surface of the vehicle body sheet metal. The middle clamping member 522 is tightly attached to the vehicle body sheet metal from bottom to top, thereby preventing the middle of the frame 10 from tilting.

[0050] The central drive member 523 can be an automatic linear drive mechanism, such as an electric push rod or a pneumatic cylinder. The central drive member 523 can also be manually driven. For example, the central drive member 523 includes a screw that is rotatably connected to the frame 10, extending parallel to the Z-direction. The screw is threadedly connected to the central clamping member 522, and rotating the screw causes the central clamping member 522 to move in the Z-direction. For ease of operation, a handle can be provided at the end of the screw, which can be operated to rotate the screw.

[0051] It should be noted that in this embodiment, when securing the frame 10 to the vehicle body, the fender locating pins 21 are first inserted downward into the locating holes on the fender, the rear support member 511 is positioned on the fender, and the middle support member 521 is positioned on the vehicle body sheet metal. In other words, the fender and body sheet metal provide an upward support force for the vehicle front assembly tool, thus reducing the operator's support force on the tooling. After the frame 10 is positioned correctly relative to the vehicle body, the rear clamping member 512 and the middle clamping member 522 are applied from bottom to top against the lower surface of the vehicle body sheet metal, thereby achieving a secure connection between the frame 10 and the vehicle body.

[0052] See also Figure 4 In some embodiments, the lock beam mounting mechanism 40 includes a lock beam locating pin 41 and a lock beam clamping assembly 42. The lock beam locating pin 41 is fixedly connected to the front end of the frame 10 to limit the movement of the lock beam in the XY plane; the lock beam clamping assembly 42 clamps the lock beam on two opposite sides in the Z direction.

[0053] Specifically, the lock beam clamping assembly 42 includes a lock beam support 421, a lock beam clamping member 422, and a lock beam driving member 423. The lock beam support 421 is fixed to the front end of the frame 10, and the lock beam positioning pin 41 is fixed to the lock beam support 421; the lock beam clamping member 422 is movably connected to the frame 10 along the Z direction, and the lock beam clamping member 422 and the lock beam support 421 are respectively supported on opposite sides of the lock beam in the Z direction; and the lock beam driving member 423 is used to drive the lock beam clamping member 422 to move.

[0054] In this embodiment, the lock beam clamping piece 422 can be set below the lock beam support piece 421. By moving the lock beam clamping piece 422 upward until the lock beam support piece 421 and the lock beam clamping piece 422 are respectively clamped on the two sides of the lock beam opposite to each other in the Z direction, the lock beam can be limited in the Z direction.

[0055] The locking beam driver 423 can be an automatic linear drive mechanism, such as an electric push rod or a pneumatic cylinder. The locking beam driver 423 can also be manually driven. For example, the locking beam driver 423 includes a screw that is rotatably connected to the frame 10, extending parallel to the Z-direction. The screw is threadedly connected to the locking beam clamp 422, and rotating the screw causes the locking beam clamp 422 to move in the Z-direction. For ease of operation, a handle can be provided at the end of the screw, which can be operated to rotate the screw.

[0056] In this embodiment, to facilitate removal of the automobile front face assembly tool after the lock beam and headlight bracket are assembled, the rear end clamping member 512, the middle clamping member 522, and the lock beam clamping member 422 are all configured to be rotatable about an axis in the Z direction. For example, the lock beam clamping member 422 is rotatably connected to the movable end of the lock beam driving member 423. When the lock beam needs to be clamped, the lock beam clamping member 422 is rotated until it faces the lower surface of the lock beam. When the tool needs to be removed, the lock beam clamping member 422 is rotated until it separates from the lower surface of the lock beam. This prevents interference between the assembled lock beam and the lock beam clamping member 422 when the tool is removed upward.

[0057] See also Figure 8 , Figure 8 yes Figure 2 A top view of the vehicle front assembly tooling in an embodiment. In some embodiments, the fender positioning mechanism 20, the headlight mounting mechanism 30, the lock beam positioning mechanism, and the tooling clamping mechanism 50 are respectively arranged in two groups symmetrically about the first central axis of the frame 10. The first central axis is a reference axis parallel to the X-axis and located in the middle of the frame 10.

[0058] The frame 10 includes a first crossbeam 11, a second crossbeam 12 and a third crossbeam 13 extending along the Y direction and arranged in sequence along the X direction. The first crossbeam 11, the second crossbeam 12 and the third crossbeam 13 are fixedly connected by a plurality of longitudinal beams 14 to form the frame 10 as a whole. Two sets of headlight mounting mechanisms 30 and two sets of lock crossbeam mounting mechanisms 40 are arranged on the first crossbeam 11, two sets of middle clamping assemblies 52 are arranged on the second crossbeam 12, and two sets of rear end clamping assemblies 51 and two sets of fender positioning mechanisms 20 are arranged on the third crossbeam 13.

[0059] It should be noted that, regarding the two sets of fender positioning mechanisms 20, one of them can limit the movement of the frame 10 in the X and Y directions, and the other only needs to limit the movement of the frame 10 in the X or Y direction. Figure 8 The fender locating mechanism 20 on the left side of the center is defined as the primary fender locating mechanism, while the fender locating mechanism 20 on the right side is defined as the secondary fender locating mechanism. The vehicle body is provided with primary and secondary fender locating holes. The primary fender locating hole is a circular hole that matches the contour of the primary fender locating pin, while the secondary fender locating hole is a waist hole with a width that matches the diameter of the secondary fender locating pin. In this embodiment, the secondary fender locating hole restricts the X-axis movement of the secondary fender locating pin, facilitating the connection between the frame 10 and the vehicle body.

[0060] Similarly, regarding the two sets of lock beam mounting mechanisms 40, the lock beam positioning pin 41 in one can limit the X-direction and Y-direction movement of the lock beam, and the lock beam positioning pin 41 in the other only needs to limit the X-direction or Y-direction movement of the lock beam.

[0061] For the sake of distinction, the following Figure 8 The lock beam mounting mechanism 40 on the left side of the center is defined as the primary lock beam mounting mechanism, while the lock beam mounting mechanism on the right side is defined as the secondary lock beam mounting mechanism. The lock beam is provided with primary lock beam positioning holes and secondary lock beam positioning holes. The primary lock beam positioning holes are circular holes that match the contour of the primary lock beam positioning pins, while the secondary lock beam positioning holes are waist holes with a width that matches the diameter of the secondary lock beam positioning pins. In this embodiment, the secondary lock beam positioning holes restrict the X-axis movement of the secondary lock beam positioning pins, facilitating the connection between the frame 10 and the lock beam.

[0062] The specific assembly steps of this embodiment are:

[0063] Match the positioning holes on the lock beam with the two lock beam positioning pins 41, and operate the lock beam driving member 423 to drive the lock beam clamping member 422 to move until it is in close contact with the lock beam;

[0064] Place the two headlight brackets on the left and right headlight positioning pins 31 respectively, operate the headlight driving member 323 to drive the headlight clamping member 322 to clamp the headlight brackets, and confirm that the moving member 332 is at the front dead center position;

[0065] Two operators work together to move the front face assembly tool to the vehicle body, align the fender locating pins 21 with the fender locating holes, fit the rear support member 511 and the middle support member 521 to the vehicle body sheet metal, and operate the rear clamping assembly 51 and the middle clamping assembly 52 to secure the frame 10 to the vehicle body.

[0066] Use tightening tools and bolts to securely connect the headlight bracket, lock beam and vehicle body;

[0067] Operate the headlight driver 323 to loosen the headlight bracket, operate the positioning pin driver 333 to drive the headlight positioning pin 31 to disengage from the positioning hole of the headlight bracket, operate the rear end driver 513, the middle driver 523, and the lock beam driver 423 to separate the rear end clamping member 512, the middle clamping member 522, and the lock beam clamping member 422 from the vehicle body respectively, and then two operators work together to remove the tooling from the vehicle body.
