[0002] With the promotion and application of new energy vehicles, range anxiety is particularly prominent. Lightweighting of vehicles is an important way to increase mileage. Replacing steel with plastic can reduce weight by 10% to 30%. Replacing metal back doors with plastic back doors is one of the application scenarios.
[0003] The inner and outer panels of the plastic tailgate are bonded together with polyurethane glue. The hinge assembly tool is an important tool in the bonding process. Its quality directly affects the gap, flushness and performance of the product. The hinge assembly tool usually positions the hinge and the inner panel through the tool, and then tightens the hinge connection bolts. Due to the large deformation of the inner panel product during injection molding and the unstable size of the positioning structure, the hinge assembly has a certain proportion of eccentricity, which leads to asymmetric left and right gaps between the plastic tailgate and the car body after it is installed on the car. For tailgates with asymmetrical left and right gaps, a rework station needs to be added to make the left and right gaps uniform and symmetrical through manual adjustment. Summary of the invention

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0020] Embodiment 1: This embodiment provides a hinge assembly tool with a repair function, specifically, Figure 1-Figure 5 As shown, it includes a hinge tooling base 1, on which a tailgate installation station is arranged, and positioning components and clamping components are installed around the tailgate installation station; after the tailgate is placed at the tailgate installation station on the hinge tooling base 1 through the positioning component, it is limited by the clamping component.
[0021] A hinge assembly mounting frame 9 is also movably provided on the hinge tooling base 1, and a hinge installation station is provided on the hinge assembly mounting frame 9. The hinge assembly mounting frame 9 moves linearly on the hinge tooling base 1; a hinge positioning component 7 and a hinge clamping component 8 are installed on the hinge assembly mounting frame 9. After the hinge 15 is placed at the hinge installation station on the hinge assembly mounting frame 9 through the hinge positioning component 7, it is limited by the hinge clamping component 8.
[0022] The hinge tooling 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, which are used to detect the eccentricity of the tailgate.
[0023] The hinge tool base 1 is also equipped with universal wheels with a locking function for easy movement.
[0024] When in use, the staff first places the hinge 15 on the hinge installation station set on the hinge assembly and installation frame 9, uses the hinge positioning component 7 to fine-tune the position of the hinge 15, and then moves the hinge clamping component 8 to fix the hinge 15. Then the tailgate is placed on the tailgate installation station set on the hinge tooling base 1, and the position of the tailgate is fine-tune using the positioning component, and then the tailgate is fixed using the clamping component. At this time, the left and right distance measuring sensors 13 on the upper side of the tailgate and the left and right distance measuring sensors 14 on the lower side of the tailgate are started, and the eccentricity of the tailgate is determined using the data measured by the left and right distance measuring sensors 13 on the upper side of the tailgate and the left and right distance measuring sensors 14 on the lower side of the tailgate; then different weights are pre-assigned to the upper and lower groups of data according to the eccentricity of the upper and lower groups of data to ensure that the left and right clearances between the tailgate and the theoretical data of the vehicle body are symmetrical and uniform; then the hinge assembly and installation frame 9 is moved to compensate for the deviation, and then the hinge 15 is installed together with the tailgate.
[0025] By real-time detection of the symmetry of the left and right gaps between the tailgate and the body's theoretical data and timely correction, the conformity of the tailgate with the theoretical data is ensured, thereby improving the first-time loading pass rate. The first-time off-line pass rate of the tailgate has been increased from about 80% to 99%. At the same time, one vehicle repair station has been optimized, shortening the loading process.
[0026] Embodiment 2: This embodiment is further expanded on the basis of the above embodiment. 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.
[0027] When the servo mechanism 11 is started, it drives the transmission mechanism 12, and the transmission mechanism 12 drives the hinge assembly and mounting frame 9 so that multiple hinges begin to move relative to the tailgate, thereby achieving compensation for deviation. The accuracy of the servo mechanism 11 is used to reduce the displacement error value of the hinge assembly and mounting frame 9, thereby improving the deviation compensation efficiency.
[0028] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.
[0029] Embodiment 3: This embodiment further expands the driving component on the basis of Embodiment 2, specifically as follows Figure 1-Figure 4As shown, the driving component also includes a linear guide rail 10 , one end of the linear guide rail 10 is connected to the hinge tooling base 1 and the other end is connected to the hinge assembly mounting frame 9 , and the hinge assembly mounting frame 9 slides linearly on the hinge tooling base 1 through the linear guide rail 10 .
[0030] 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 operation of the hinge assembly mounting frame 9 and prevents the servo mechanism 11 from being deformed and damaged due to a force that is not coaxial with the output power direction.
[0031] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.
[0032] Embodiment 4: This embodiment further expands the positioning component on the basis of the above embodiment. Figure 1-Figure 4 As shown, the positioning component includes a tailgate main positioning component 2 and two tailgate secondary positioning components 3, and the tailgate main positioning component 2 and tailgate secondary positioning components 3 are both fixed on the hinge tooling base 1, and the tailgate is positioned by the tailgate main positioning component 2 and the tailgate secondary positioning component 3. The tailgate main positioning component 2 controls the X-axis and Y-axis positions of the tailgate, and the tailgate secondary positioning component 3 controls the rotation position of the tailgate.
[0033] Since the specifications and sizes of different tailgates vary, in order to ensure that the hinge 15 and the tailgate can be assembled, 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.
[0034] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.
[0035] Embodiment 5: This embodiment further expands the pressing component on the basis of the above embodiment. Figure 1-Figure 4 As shown, the clamping components include a tailgate clamping assembly A4, a tailgate clamping assembly B5, and a tailgate clamping assembly C6. The tailgate clamping assembly A4, the tailgate clamping assembly B5, and the tailgate clamping assembly C6 respectively clamp the front and rear, upper and lower positions of the tailgate.
[0036] The tailgate is clamped and locked in all directions by the tailgate clamping assembly A4, the tailgate clamping assembly B5 and the tailgate clamping assembly C6, so as to effectively prevent the tailgate from moving during assembly and improve assembly stability.
[0037] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.
[0038] Embodiment 6: This embodiment is further expanded on the basis of the above embodiment. 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 feedback the displacement data of the hinge assembly mounting frame 9 in real time.
[0039] By providing the hinge assembly mounting frame displacement sensor 16, the staff can more intuitively understand the displacement data of the hinge assembly mounting frame 9, and reversely check to ensure whether the displacement data output by the servo mechanism 11 is correct, thereby ensuring that the deviation correction is accurate.
[0040] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.
[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
