Description

Technical Field

[0001] The present invention relates to the technical field of automobile headlight installation, and more particularly to a headlight bracket auxiliary assembly tool. Background Art

[0002] During the automotive assembly process, the positional accuracy of mounting points is critical to ensure component assembly is in place. If a headlight has an off-center hole during assembly, it can cause dimensional deviations, directly impacting the vehicle's exterior quality and the lifespan of the headlights. Therefore, the precision of the headlight mounting holes must be extremely high, ensuring precise three-dimensional spacing between the headlights and the hood, fenders, and front bumper.

[0003] Currently, headlight brackets are manually assembled on the adjustment line. Due to the poor consistency of manual assembly, the headlight body mounting holes are prone to deviation in the X / Z directions. This leads to misalignment during final assembly, resulting in inconsistent clearances and surface differences between the headlights and the hood, fenders, and front bumper. This results in rework, wasted work hours, and reduced production efficiency.

[0060] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0061] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0062] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0063] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0064] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0065] according to Figures 1 to 13As shown, a headlight bracket auxiliary assembly tool includes a frame, a fixture positioning and pressing mechanism 3, a bracket positioning mechanism 7, a vehicle body supporting mechanism 6 and a fender positioning mechanism 5.

[0066] The frame consists of two perpendicular horizontal bars 1 and vertical bars 2. A connecting rod is attached to one end of the horizontal bar 1. The fixture's positioning and clamping mechanism 3 is located at the lower end of the connecting rod and is used to secure the frame to the vehicle's engine bay cover 104. The frame, consisting of two square frames, serves as the carrier for the auxiliary assembly tool for the headlight mounting bracket. Its primary function is to support and connect the various mechanisms of the fixture. The square tubes are made of carbon fiber to reduce the overall weight of the frame and enhance the fixture's portability.

[0067] The crossbar 1 is also provided with a connecting plate 11, and the connecting plate 11 is provided with a slide rail 12, which is parallel to the crossbar 1; the vertical bar 2 is provided with a sliding mechanism 4 on the side facing the crossbar 1, and the sliding mechanism 4 and the vertical bar 2 move left and right along the slide rail 12.

[0068] The fender positioning mechanism 5 is provided at the top of the vertical rod 2 , and is used to cooperate with the headlight positioning point on the fender 101 .

[0069] The vehicle body supporting mechanism 6 is arranged on the lower side of the cross bar 1 and cooperates with the engine compartment longitudinal beam 103 .

[0070] The bracket positioning mechanism 7 is provided on the top of the vertical rod 2 and is used for adsorbing and fixing the headlight bracket 102 so that the headlight bracket 102 is fixedly connected to the vehicle body by screws.

[0071] The present invention uses an auxiliary fixture for the headlight bracket 102 to ensure that the final assembly position of the headlight bracket 102 is accurate, solves the problem of poor headlight assembly position accuracy and stability, and improves the final appearance quality of the vehicle body. Secondly, because the X-axis dimension of the fender 101 changes with the influence of the door assembly position, the bracket position can be adjusted through the sliding mechanism 4 to ensure that the relative positions of the headlight bracket 102 installation point and the headlight positioning point on the fender 101 remain linked, compensating for the assembly error of the previous process. It effectively ensures the assembly accuracy of the headlight bracket 102, ensures the stability of the assembly dimensions, and improves the aesthetics of the entire vehicle assembly. It greatly reduces the impact of personnel quality on assembly, reduces the assembly technical requirements for operators, eliminates the need for manual adjustment, reduces the difficulty of assembly operations, improves production efficiency, and ensures assembly quality.

[0072] Further, if Figure 4 As shown, the harness positioning mechanism 32 includes a connecting rod mechanism 31 and a positioning mechanism 32. Figure 6As shown, the positioning mechanism 32 includes a T-shaped block 321, a first adapter block 322, a first L-shaped block 323 and a first pin seat 324. The horizontal surface of the T-shaped block 321 is connected to the lower surface of the connecting rod, and the vertical surface is connected to the first adapter block 322. The vertical surface of the first L-shaped block 323 is connected to the side of the first adapter block 322 adjacent to the T-shaped block 321, and the horizontal surface of the first L-shaped block 323 is perpendicular to the horizontal and vertical surfaces of the T-shaped block 321. The first pin seat 324 is connected below the horizontal surface of the first L-shaped block 323, and a first positioning pin 325 is provided on the side away from the T-shaped block 321. The first pin seat 324 is also provided with second magnets 326 on both sides of the first positioning pin 325 to further increase the connection stability with the vehicle body.

[0073] like Figure 5 As shown, the connecting rod mechanism 31 includes an operating handle 312, a pressure head 315, a connecting block 313, and a second adapter block 311. The second adapter block 311 is fixedly connected to the end of the first pin seat 324 away from the first positioning pin 325. The operating handle 312 is connected to the second adapter block 311 via a rotating shaft. The connecting block 313 is rotatably connected to the second adapter block 311 and is rotatably connected to the operating handle 312 via the connecting rod 314. The pressure head 315 is arranged on the connecting block 313 and corresponds to the first positioning pin 325. The handle can drive the connecting block 313 and the pressure head 315 away from or close to the first positioning pin 325. By pressing the operating handle 312 downward, the connecting block 313 is driven to rotate around the rotation axis, thereby driving the pressure head 315 to rotate outward around the rotation axis, causing the fixture positioning and clamping mechanism 3 to open. The opening angle of the clamping mechanism is limited by the position of the angle limit block 316. The connecting rod mechanism 31 mainly connects the second adapter block 311 and the first pin seat 324 of the positioning mechanism 32 through two screws.

[0074] The function of the fixture positioning and clamping mechanism 3 is to clamp and fix the entire mechanism. Through the connecting rod principle, the first positioning pin 325 is inserted into the positioning hole of the vehicle body's engine compartment cover plate 104, so that the second magnet 326 is adsorbed on the surface of the engine compartment cover plate 104, and then the operating handle 312 is lifted to make the pressure head 315 fit with the inner surface of the cover plate, thereby fixing the entire fixture positioning and clamping mechanism 3 to the vehicle body to ensure the stability of the mechanism.

[0075] Furthermore, shims are provided between the T-shaped block 321 and the first adapter block 322, between the first adapter block 322 and the first L-shaped block 323, and between the first L-shaped block 323 and the first pin holder 324 to adjust the position of the first locating pin 325 along the X, Y, and Z axes. By adjusting the number of shims in different directions, the position of the first locating pin 325 can be adjusted to ensure that the first locating pin 325 is accurately inserted into the vehicle body and positioned.

[0076] Further, if Figure 7 and Figure 8As shown, the sliding mechanism 4 includes a second L-shaped block 41 and a retaining slot 42. The vertical surface of the second L-shaped block 41 is connected to the vertical rod 2, and the horizontal surface is connected to the retaining slot 42. The lower side of the retaining slot 42 is provided with a slide groove 43 that mates with the slide rail 12. Because the X-axis dimension of the fender 101 changes with the door assembly position, the sliding mechanism 4 enables the position adjustment of the fender positioning mechanism 5 and the bracket positioning mechanism 7, ensuring that the relative positions of the headlight bracket 102 mounting point and the headlight positioning point on the fender 101 remain linked.

[0077] Furthermore, the sliding mechanism 4 also includes a cover plate 44 and a limit pin 45. The cover plate 44 is connected between the lower surface of the second L-shaped block 41 and the limit slot 42. Pin bushings 46 are positioned correspondingly on the cover plate 44 and the connecting plate 11. The limit pin 45 can be inserted into the two pin bushings 46 to relatively fix the sliding mechanism 4 and the connecting plate 11. Removing the limit pin 45 from the sliding mechanism 4 allows the sliding mechanism 4 to slide back and forth along the slide rail 12, driving the fender positioning mechanism 5 and the bracket positioning mechanism 7 to slide back and forth. This allows the fender 101 positioning pin and the headlight bracket 102 to be adjusted. The limit pin 45 is inserted into the pin hole in the cover plate 44 and cooperates with the pin bushing 46 to limit the sliding of the sliding mechanism 4. The cover plate 44 primarily supports the limit pin 45 and connects the limit slot 42 to the second L-shaped block 41. The upper surface of the cover plate 44 is secured to the lower portion of the second L-shaped block 41 via hexagon socket bolts, while the lower surface is secured to the upper surface of the retaining slot 42. The second L-shaped block 41 is secured to the vertical rod 2 via arc welding. The slide rail 12 primarily supports the retaining slot 42, allowing it to slide along the path of the slide rail 12. The slide rail 12 is secured to the connecting plate 11 via locking screws.

[0078] Furthermore, according to the auxiliary assembly tool for the headlight bracket 102 of the present invention, a limit block 13 is further provided at one end of the connecting plate 11 away from the pin sleeve 46 , and the limit block 13 is used to limit the maximum stroke of the sliding mechanism 4 .

[0079] Further, if Figure 2 and Figure 9 As shown, the bracket positioning mechanism 7 includes a third adapter block 71, a fourth adapter block 72, a fifth adapter block 73, a sixth adapter block 76, a third L-shaped block 77, a second pin holder 78, and a locking pin 79. One side of the third adapter block 71 is connected to the bottom end of the vertical rod 2, and the fourth adapter block 72 and the fifth adapter block 73 are arranged on the other side of the third adapter block 71. The fourth adapter block 72 extends downward and is provided with support blocks 74 on its left and right sides. The support blocks 74 are provided with multiple first magnets 75. The first magnets 75 are used to attract the headlight bracket 102 to be installed.

[0080] The side of the fifth adapter block 73 away from the fourth adapter block 72 is connected to the sixth adapter block 76, the horizontal surface of the third L-shaped block 77 is connected to the bottom surface of the sixth adapter block 76, the second pin seat 78 is connected to the side of the vertical surface of the third L-shaped block 77 close to the support block 74, and a locking pin 79 is threadedly connected to the second pin seat 78, and the locking pin 79 is used to fix the headlight bracket 102 to be installed.

[0081] The locking pin 79 is threadedly secured to the upper surface of the second pin holder 78. The second pin holder 78 and support block 74 are respectively secured to the sides of the third L-shaped block 77 and fourth adapter block 72 via locking screws. Seven first magnets 75 are provided to secure the headlight bracket 102. The bracket positioning mechanism 7 primarily connects the third adapter block 71 to the vertical rod 2 through arc welding.

[0082] Furthermore, shims are provided between the fourth adapter block 72 and the support blocks 74 on both sides, between the third adapter block 71 and the fifth adapter block 73, between the sixth adapter block 76 and the third L-shaped block 77, and between the third L-shaped block 77 and the second pin holder 78 to adjust the position of the support blocks 74 and the locking pin 79. The position of the second pin holder 78 and the support block 74 can be adjusted by adding or removing shims.

[0083] Furthermore, if Figure 10 As shown, the fender positioning mechanism 5 includes a fourth L-shaped block 51, a third pin seat 52 and a second positioning pin 53. The horizontal surface of the fourth L-shaped block 51 is connected to the top of the vertical rod 2, and the third pin seat 52 is connected to the vertical surface of the fourth L-shaped block 51, and a gasket is provided between the two. The second positioning pin 53 is arranged at the end of the third pin seat 52, which is used to cooperate with the headlight positioning point on the fender 101.

[0084] The fender positioning mechanism 5 mainly plays the role of positioning the fender 101. The headlight mounting point needs to be linked with the headlight positioning point on the fender 101. Therefore, the assembly tool of the headlight bracket 102 needs to be linked with the position of the fender 101. The fender positioning mechanism 5 is mainly composed of a second positioning pin 53, a third pin seat 52 and a fourth L-shaped block 51. The second positioning pin 53 is inserted into the positioning hole on the fender 101 to realize the Z-direction positioning of the fixture on the fender 101. A limiting groove is provided on the third pin seat 52. Rotating the second positioning pin 53 drives the second positioning pin 53 to move up and down along the limiting groove to realize the extension and retraction of the second positioning pin 53. The pin seat is connected to the fourth L-shaped block 51 by a screw, and there is a gasket between the two. The position of the second positioning pin 53 can be adjusted by adding or removing the gasket.

[0085] Furthermore, if Figure 11As shown, the vehicle body support mechanism 6 includes a fifth L-shaped block 61, a sixth L-shaped block 62, a seventh L-shaped block 63, and two pressing blocks 64. The horizontal surface of the fifth L-shaped block 61 is connected to the lower surface of the crossbar 1. The vertical surfaces of the sixth L-shaped block 62 and the seventh L-shaped block 63 are connected to the same side of the vertical surface of the fifth L-shaped block 61 and are perpendicular to each other. The two pressing blocks 64 are respectively arranged on the opposite sides of the horizontal surfaces of the sixth L-shaped block 62 and the seventh L-shaped block 63. Gaskets are provided between the pressing blocks 64 and the connected sixth L-shaped blocks 62 and seventh L-shaped blocks 63 to adjust the distance between the two pressing blocks 64.

[0086] The vehicle body support mechanism 6 primarily supports the launch bay longitudinal beam 103 and prevents the mounting from falling due to gravity. It consists of a fifth L-shaped block 61, a sixth L-shaped block 62, a seventh L-shaped block 63, and two clamping blocks 64. The two clamping blocks 64 are connected to the sixth and seventh L-shaped blocks 62 and 63, respectively, via two screws, with a shim between them. The Z-axis height of the two clamping blocks 64 can be adjusted by adding or removing the shim. The vehicle body support mechanism 6 primarily connects the fifth L-shaped block 61 to the vertical bar 2 through arc welding.

[0087] For example Figure 12 As shown, the present invention also includes an auxiliary positioning mechanism 9, which primarily assists in positioning the harness on the vehicle body, ensuring accurate attachment of the harness to the vehicle body. The mechanism comprises an auxiliary positioning pin 92 and a fourth pin holder 91. The auxiliary positioning pin 92 is threadedly secured to the positioning pin hole of the fourth pin holder 91. The fourth pin holder 91 is secured to the lower surface of the crossbar 1 primarily by arc welding.

[0088] For example Figure 13 As shown, the present invention also includes an auxiliary clamping mechanism 8, which mainly serves to assist in clamping and positioning the fixture on the vehicle body. It is composed of an auxiliary clamping block 82 and a seventh adapter block 81. The auxiliary clamping block 82 is required to fit the upper surface of the longitudinal beam 103 of the engine compartment to ensure that the fixture is accurately fixed to the vehicle body. The auxiliary clamping block 82 is connected to the seventh adapter block 81 by two screws, with a gasket between the two. The position of the auxiliary clamping block 82 can be adjusted by adding or removing the gasket. The seventh adapter block 81 is mainly fixed to the lower surface of the crossbar 1 by arc welding.

[0089] For example Figure 14 and Figure 15The figure shows an assembly diagram of the present invention. First, the fixture is positioned on the vehicle body: the first positioning pin 325 is inserted into the positioning hole of the vehicle body's hair compartment cover plate 104 through the fixture positioning and clamping mechanism 3, so that the second magnet 326 is adsorbed on the surface of the hair compartment cover plate 104. Then, the auxiliary positioning pin 92 is inserted into the front overhang mounting hole through the auxiliary positioning mechanism 9, and the auxiliary clamping mechanism 8 is fitted with the hair compartment longitudinal beam 103 to ensure that the fixture is positioned stably on the vehicle body. At the same time, ensure that the clamping block 64 of the vehicle body support mechanism 6 is fitted with the upper and lower flanges of the hair compartment longitudinal beam 103, and then lift the operating handle 312 to fit the pressure head 315 with the inner surface of the hair compartment cover plate 104, thereby fixing the entire fixture positioning and clamping mechanism 3 to the vehicle body.

[0090] After the fixture is positioned and stabilized on the vehicle body, remove the limit pin 45 of the sliding mechanism 4 and push the fender positioning mechanism 5 to slide back and forth along the slide rail 12. After the second positioning pin 53 of the fender positioning mechanism 5 is inserted into the positioning hole on the vehicle body fender 101, the second positioning pin 53 is locked. Then, the headlight bracket 102 is placed on the support block 74 of the bracket positioning mechanism 7, and the locking pin 79 is locked and fixed on the second pin seat 78. The strong adsorption effect of the first magnet 75 ensures that the headlight bracket 102 is stably adsorbed on the support block 74 and the second pin seat 78. At this time, the bolts of the headlight bracket 102 are tightened manually with an electric gun to achieve the connection and fixation between the headlight bracket 102 and the vehicle body.

[0091] Because the X-dimensional dimensions of the fender 101 vary depending on the door assembly position, the sliding mechanism 4 enables positional adjustment of the bracket positioning mechanism 7 and the fender positioning mechanism 5, ensuring that the relative positions of the mounting point of the headlight bracket 102 and the headlight positioning point on the fender 101 remain linked. The sliding mechanism 4 enables coordinated adjustment of the X-dimensional dimensions of the headlight bracket 102 to match the fender 101, effectively ensuring the relative positions of the mounting point of the headlight bracket 102 and the headlight positioning point on the fender 101, compensating for manufacturing and assembly errors in previous processes, and enabling quick and convenient manual installation of the headlight bracket 102. This significantly reduces the assembly skill requirements for the operator and improves the aesthetics of the overall vehicle assembly.

It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
