Description

Technical Field

[0001] This utility model relates to the field of automotive manufacturing tooling technology, specifically, a hinge assembly tooling with rework function. Background Technology

[0002] With the promotion and application of new energy vehicles, range anxiety has become particularly prominent. Lightweighting of vehicles is an important way to increase driving range. Replacing steel with plastic can reduce weight by 10% to 30%, and replacing metal tailgates with plastic tailgates is one such application scenario.

[0003] The inner and outer panels of the plastic tailgate are bonded together with polyurethane adhesive. The hinge assembly fixture is a crucial tool in the bonding process, and its quality directly affects the product's clearance, surface difference, and performance. The hinge assembly fixture typically positions the hinge and inner panel, then tightens the hinge connecting bolts. Due to the large injection molding deformation of the inner panel and the instability of the positioning structure dimensions, a certain degree of eccentricity occurs in the hinge assembly. This results in an asymmetrical left-right clearance between the plastic tailgate and the vehicle body after installation. Tailgates with asymmetrical left-right clearance require an additional rework station for manual adjustment to ensure uniform and symmetrical clearance. Utility Model Content

[0004] The purpose of this utility model is to provide a hinge assembly fixture with a repair function to solve the problem of asymmetrical gaps between the tailgate and the vehicle body caused by hinge assembly eccentricity.

[0005] This utility model is achieved through the following technical solution: a hinge assembly fixture with rework function, including a hinge fixture base, a tailgate installation station provided on the hinge fixture base, and positioning components and clamping components installed around the tailgate installation station; after the tailgate is placed on the tailgate installation station on the hinge fixture base by the positioning components, it is limited by the clamping components; a movable hinge assembly and mounting frame is also provided on the hinge fixture base, and a hinge installation station is provided on the hinge assembly and mounting frame, which moves linearly on the hinge fixture base; a hinge positioning component and a hinge clamping component are installed on the hinge assembly and mounting frame, and the hinge is placed on the hinge assembly and mounting frame by the hinge positioning component and fixed by the hinge clamping component; a tailgate upper left and right distance sensor and a tailgate lower left and right distance sensor are also installed on the hinge fixture base, and the tailgate upper left and right distance sensors and tailgate lower left and right distance sensors are used to detect the tailgate's eccentricity.

[0006] To better realize this utility model, the hinge tooling base is further provided with a driving component for driving the hinge assembly mounting frame to move. The driving component includes a servo mechanism and a transmission mechanism. The output end of the servo mechanism is connected to the transmission mechanism, and the transmission mechanism is connected to the hinge assembly mounting frame.

[0007] To better realize this utility model, the driving component further includes a linear guide rail, one end of which is connected to the hinge tooling base and the other end of which is connected to the hinge assembly mounting bracket. The hinge assembly mounting bracket slides linearly on the hinge tooling base via the linear guide rail.

[0008] To better realize this utility model, the positioning component further includes multiple tailgate main positioning components and tailgate secondary positioning components. The tailgate main positioning components and tailgate secondary positioning components are all fixedly connected to the hinge tooling base, and the tailgate is positioned by the tailgate main positioning components and tailgate secondary positioning components.

[0009] To better realize this utility model, the pressing component further includes tailgate pressing component A, tailgate pressing component B, and tailgate pressing component C, which respectively press the front and rear, and top and bottom positions of the tailgate.

[0010] To better realize this utility model, the hinge tooling base is further equipped with a hinge assembly mounting frame displacement sensor for real-time display and feedback of the hinge assembly mounting frame displacement data.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model detects the symmetry of the left and right gap between the tailgate and the vehicle body in real time and corrects any deviations in time, ensuring that the tailgate conforms to the theoretical data, thereby improving the first-time assembly pass rate. The first-time off-line pass rate of the tailgate has been increased from about 80% to 99%, eliminating one whole vehicle rework station, shortening the assembly process, and improving the first-time assembly pass rate, thus having good practicality.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1:

[0021] This embodiment provides a hinge assembly fixture with rework functionality, specifically as follows: Figure 1-Figure 5 As shown, it includes a hinge fixture base 1, on which a tailgate installation station is provided. Positioning components and clamping components are installed around the tailgate installation station. After the tailgate is placed on the tailgate installation station on the hinge fixture base 1 by the positioning components, it is limited by the clamping components.

[0022] A hinge assembly and mounting frame 9 is movably mounted on the hinge fixture base 1. The hinge assembly and mounting frame 9 is provided with a hinge installation station. The hinge assembly and mounting frame 9 moves linearly on the hinge fixture base 1. The hinge assembly and mounting frame 9 is equipped with a hinge positioning component 7 and a hinge clamping component 8. After the hinge 15 is placed on the hinge installation station on the hinge assembly and mounting frame 9 through the hinge positioning component 7, it is limited by the hinge clamping component 8.

[0023] The hinge fixture base 1 is also equipped with a tailgate upper left and right distance measuring sensor 13 and a tailgate lower left and right distance measuring sensor 14. The tailgate upper left and right distance measuring sensor 13 and the tailgate lower left and right distance measuring sensor 14 are used to detect the tailgate's eccentricity.

[0024] The hinge tooling base 1 is also equipped with casters with locking function for easy movement.

[0025] In use, the operator first places the hinge 15 on the hinge mounting bracket 9 at the hinge installation position, fine-tunes the position of the hinge 15 using the hinge positioning component 7, and then moves the hinge clamping component 8 to fix the hinge 15. Next, the tailgate is placed on the hinge fixture base 1 at the tailgate installation position, fine-tunes the position of the tailgate using the positioning component, and then fixes the tailgate using the clamping component. At this point, the upper left-right distance sensors 13 and the lower left-right distance sensors 14 of the tailgate are activated. The data measured by the upper left-right distance sensors 13 and the lower left-right distance sensors 14 are used to determine the tailgate's eccentricity. Then, based on the eccentricity of the two sets of data, different weights are pre-assigned to the upper and lower sets of data to ensure that the theoretical left-right gap between the tailgate and the vehicle body is symmetrical and uniform. The hinge mounting bracket 9 is then moved to compensate for the eccentricity, and finally, the hinge 15 is installed together with the tailgate.

[0026] By real-time detection of the symmetry of the left and right gaps between the tailgate and the vehicle body according to theoretical data, and timely correction of any deviations, the tailgate's conformity with the theoretical data is ensured, thereby improving the first-time assembly pass rate. The first-time off-line pass rate of the tailgate has increased from about 80% to 99%. At the same time, one vehicle rework station has been eliminated, shortening the assembly process.

[0027] Example 2:

[0028] This embodiment further extends the above embodiment, specifically as follows: Figure 1-Figure 4 As shown, the hinge tooling base 1 is also provided with a driving component for driving the hinge assembly mounting frame 9 to move. The driving component includes a servo mechanism 11 and a transmission mechanism 12. The output end of the servo mechanism 11 is connected to the transmission mechanism 12, and the transmission mechanism 12 is connected to the hinge assembly mounting frame 9.

[0029] When the servo mechanism 11 is started, it drives the transmission mechanism 12. The transmission mechanism 12 drives the hinge assembly mounting frame 9, causing multiple hinges to begin to move relative to the tailgate, thereby achieving correction compensation. The precision of the servo mechanism 11 reduces the displacement error value of the hinge assembly mounting frame 9 and improves the correction efficiency.

[0030] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0031] Example 3:

[0032] This embodiment further expands the driving component based on embodiment 2, specifically as follows: Figure 1-Figure 4 As shown, the driving component also includes a linear guide rail 10, one end of which is connected to the hinge tooling base 1 and the other end is connected to the hinge assembly mounting frame 9. The hinge assembly mounting frame 9 slides linearly on the hinge tooling base 1 via the linear guide rail 10.

[0033] When the servo mechanism 11 drives the transmission mechanism 12 to move the hinge assembly mounting frame 9, the linear guide rail 10 can ensure that the hinge assembly mounting frame 9 maintains linear movement. The linear guide rail 10 improves the smoothness of the hinge assembly mounting frame 9's operation and prevents the servo mechanism 11 from being deformed or damaged by forces that are not on the same axis as the output power direction.

[0034] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0035] Example 4:

[0036] This embodiment further expands the positioning component based on the above embodiment, specifically as follows: Figure 1-Figure 4 As shown, the positioning components include a main tailgate positioning assembly 2 and two secondary tailgate positioning assemblies 3. Both the main tailgate positioning assembly 2 and the secondary tailgate positioning assemblies 3 are fixed to the hinge fixture base 1, and the tailgate is positioned using these components. The main tailgate positioning assembly 2 controls the tailgate's X-axis and Y-axis positions, while the secondary tailgate positioning assemblies 3 control the tailgate's rotational position.

[0037] Since different tailgate specifications and dimensions may vary, in order to ensure that the hinge 15 can be assembled with the tailgate, the tailgate main positioning assembly 2 and the tailgate secondary positioning assembly 3 will ensure that each tailgate is installed in the correct position on the hinge tooling base 1.

[0038] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0039] Example 5:

[0040] This embodiment further expands the clamping component based on the above embodiment, specifically as follows: Figure 1-Figure 4 As shown, the pressing components include tailgate pressing assembly A4, tailgate pressing assembly B5, and tailgate pressing assembly C6, which respectively press the tailgate in front and behind, and in the top and bottom.

[0041] The tailgate is fully clamped and locked by tailgate clamping components A4, B5, and C6, effectively preventing the tailgate from moving during assembly and improving assembly stability.

[0042] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0043] Example 6:

[0044] This embodiment further extends the above embodiment, specifically as follows: Figure 1 , Figure 2 As shown, a hinge assembly mounting frame displacement sensor 16 is also installed on the hinge tooling base 1, which is used to display and provide real-time feedback on the displacement data of the hinge assembly mounting frame 9.

[0045] By setting the hinge assembly mounting bracket displacement sensor 16, the staff can more intuitively understand the displacement data of the hinge assembly mounting bracket 9, and reverse check to ensure that the displacement data output by the servo mechanism 11 is correct, thus ensuring accurate correction.

[0046] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
