Description

Technical Field

[0001] This application relates to the field of automotive component testing technology, and in particular to a matching fixture for a rear quarter window assembly. Background Technology

[0002] With the rapid development of automobile manufacturing technology, the rear quarter window, as an important functional and decorative component of the vehicle body side panel, directly affects the vehicle's sealing, NVH performance, and appearance quality through its assembly accuracy. Traditional inspection methods mostly rely on manual visual inspection or simple tooling, resulting in low efficiency and poor consistency. In recent years, inspection fixtures have become the core tool for controlling the dimensions and matching accuracy of the quarter window assembly due to their high efficiency and standardization advantages.

[0003] In the prior art, such as the Chinese patent application "Inspection Fixture for Left Rear Side Triangular Window Assembly" (publication number: CN111551100A), the inspection fixture is disclosed to include a base plate, a sliding stage, a limiting pin, a flipping mechanism one, a dial indicator, a cross laser pointer, a clamping mechanism, a clamping mechanism opening and closing control mechanism, a side detection block, a flipping mechanism two, and a simulation block. The sliding stage is slidably connected to the base plate, the side detection block is fixed on the sliding stage, the limiting pin is provided on the sliding stage, and several pin holes for the limiting pin to pass through are opened on the base plate. Several flipping mechanisms one and several flipping mechanisms two are fixed on the base plate. A dial indicator is fixed on flipping mechanism one and a dial indicator is fixed on flipping mechanism two.

[0004] For example, Chinese patent application "A Grip for an Automobile Triangular Window Assembly", publication number: CN216523753U, discloses a fixture including a base, a bracket mounted on one side of the upper part of the base, electric telescopic rods mounted on both sides of the top of the bracket, a support plate connected to the other end of the electric telescopic rods, and the other end of the support plate connected to the upper part of the base via a connecting shaft. The support plate has an installation slot for storing the mounting plate inside, and a mounting plate fixing assembly for fixing the mounting plate is installed on the left side of the installation slot.

[0005] However, existing inspection tools still have shortcomings in simulating the actual installation environment of the rear quarter window, leading to discrepancies between the inspection results and the actual assembly effect. Existing tooling simplifies the simulated structure and fails to reproduce the complete geometric features and constraints of the vehicle body installation area, resulting in discrepancies between the inspection data and the actual assembly effect. Therefore, a matching tooling that can highly reproduce the rear quarter window installation environment is needed to improve the reliability and guidance of inspection results, providing a more accurate predictive basis for the overall vehicle assembly quality. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a matching fixture for the rear quarter window assembly, which constructs a more complete installation environment simulation structure, thereby realizing the simulation of assembly conditions and further improving the detection accuracy.

[0007] The technical solution adopted in this application is as follows: a rear triangular window assembly matching fixture, including a frame, a base plate vertically mounted on the frame, a base fixedly mounted on the base plate, the base being an outer frame structure, the top surface of the base forming a lower simulation base, a plurality of mounting seats being provided on the outer periphery of the base, upper simulation blocks being detachably mounted on the mounting seats, all the upper simulation blocks being spliced ​​together to form an upper simulation base, and the outer edge of the rear triangular window assembly to be tested being installed between the upper simulation base and the lower simulation base.

[0008] Compared with existing technologies, the advantages of this application are as follows: First, by constructing a lower simulation seat through the base outer frame, and cooperating with the upper simulation seat composed of detachable upper simulation blocks, a complete clamping structure is formed, which accurately simulates the installation boundary conditions of the rear quarter window on the side of the vehicle body. This dual-layer simulation structure can completely restore the mating surface contour of the vehicle body sheet metal parts, solving the detection distortion problem caused by traditional inspection tools only simulating one side of the contact surface.

[0009] Secondly, the upper simulation block adopts a split, detachable installation structure, allowing it to adapt to different vehicle models or rear quarter window assemblies of different shapes by replacing different sizes of the upper simulation block, thus exhibiting good versatility and expandability. Furthermore, damaged modules can be replaced individually after localized wear. This not only reduces equipment costs for enterprises but also extends the service life of the inspection tool.

[0010] In some embodiments of this application, the base is composed of multiple base blocks, and each base block corresponds to a mounting base.

[0011] Preferably, the base block and the mounting base are integrally formed. By fixing the relative position between the mounting base and the base block, the relative position between the upper module and the base block is ensured.

[0012] The modular design allows the base to be flexibly adjusted and assembled according to the dimensions of different vehicle models or rear quarter window assemblies. This structure not only improves the versatility and adaptability of the fixture, but also facilitates the quick replacement of damaged base blocks in case of partial damage, reducing maintenance costs and equipment downtime. In addition, the modular base design also facilitates transportation and storage, further enhancing the practicality and economy of the fixture.

[0013] In some embodiments of this application, one side of the upper simulation block extends outward to form a mounting block, which is placed above the mounting base, and the bottom surface of the mounting block is in contact with the top surface of the mounting base.

[0014] This design enables rapid positioning and installation of the upper simulation block. The extended structure of the mounting block not only provides additional support area and enhances connection stability but also simplifies the installation process and improves operational efficiency. Furthermore, the close fit design between the mounting block and the mounting base effectively transmits force and torque, ensuring a tight fit between the upper simulation block and the base during testing, thereby improving testing accuracy and repeatability.

[0015] In some embodiments of this application, the mounting base is provided with a positioning hole and two insertion holes, with the two insertion holes located on both sides of the positioning hole.

[0016] Positioning holes and insertion holes are provided on the mounting base, offering a precise positioning and fixing method for the upper simulation block. This dual positioning and fixing method not only improves the accuracy and stability of the installation but also enhances the overall rigidity of the structure, reducing detection deviations caused by installation errors. Simultaneously, this design facilitates quick disassembly and replacement of the upper simulation block, improving the versatility and maintenance efficiency of the fixture.

[0017] In some embodiments of this application, a locking member is installed on the mounting block, and two pins are provided on the mounting block. The bottom of the locking member and the bottom of the pins protrude from the mounting block. When the mounting block is stacked on top of the mounting base, the two pins correspond one-to-one with the two sockets, the bottom of the pins are inserted into the sockets, and the bottom of the locking member extends into the positioning hole.

[0018] The design of the locking element and pin ensures the upper simulation block is securely fixed to the mounting base. The bottom of the locking element extends into the positioning hole, providing vertical fixing force, while the pin inserts into the socket, providing horizontal constraint. This dual fixing method ensures the stability of the upper simulation block during the inspection process, preventing loosening due to vibration or external forces. At the same time, the combination of the locking element and pin simplifies the installation and disassembly process, improves operational efficiency, and further enhances the practicality and reliability of the inspection fixture.

[0019] In some embodiments of this application, the locking member consists of a cap, a rod, and a locking part from top to bottom. The outer diameter of the cap is larger than the outer diameter of the rod, and the outer diameter of the locking part is larger than the outer diameter of the rod. The locking part passes through the mounting block and is locked in place with the positioning hole.

[0020] The cap provides a convenient gripping area, the rod connects and transmits force, and the locking part securely fixes the device through its engagement with the positioning hole. The segmented structure also makes installation and removal of the locking mechanism easier, reducing operational complexity. Furthermore, the tight fit between the locking part and the positioning hole effectively prevents loosening, ensuring the stability of the upper simulation block during testing, thereby improving testing accuracy and reliability.

[0021] Specifically, this application can be configured such that the locking part and the positioning hole are connected by an interference fit to achieve locking, or the locking part and the positioning hole can be connected by a thread to achieve locking.

[0022] In some embodiments of this application, the mounting block is provided with a stepped hole, which includes a main hole and a secondary hole. The secondary hole is located above the main hole and is adapted to the size of the rod. The diameter of the main hole is greater than or equal to the outer diameter of the locking part. The locking part can be housed in the main hole or extend out of the main hole and connect with the positioning hole. A spring is provided on the outer sleeve of the screw located above the mounting block.

[0023] The stepped hole design provides flexible installation and storage space for the locking component. The secondary hole adapts to the rod size, ensuring the positioning accuracy of the locking component during installation; while the larger diameter of the main hole allows sufficient space for the locking component to be stored, avoiding installation difficulties caused by size limitations. This design not only improves the efficiency of installation and disassembly but also provides cushioning for the locking component through the elasticity of the spring, reducing damage caused by impact or vibration. At the same time, the stepped hole design also makes the installation of the locking component more stable, further improving the reliability and accuracy during the testing process.

[0024] In some embodiments of this application, a plurality of detection seats are provided outside the base, and a dial indicator seat is rotatably mounted on the detection seat. The dial indicator seat is provided with at least one dial indicator hole, which is located above the rear triangular window assembly to be tested, and the dial indicator hole is equipped with a dial indicator.

[0025] This design, with its flip-up dial indicator base and dial indicator hole, provides more convenient installation space for mounting the rear quarter window assembly to be tested. The dial indicator hole, located above the rear quarter window assembly, ensures the accuracy and consistency of the measurement points. This design not only enhances the flexibility and adaptability of the testing process but also reduces errors caused by inaccurate measurement positions, further improving the reliability of the test results.

[0026] In some embodiments of this application, one of the mounting bases is provided with a movable positioning pin, one end of which extends between the upper and lower simulation bases.

[0027] The movable locating pin design provides a precise positioning reference for the installation of the rear quarter window assembly. One end of the locating pin extends between the upper and lower simulation seats, effectively constraining the position of the rear quarter window assembly and ensuring its stability during inspection. This design not only improves inspection accuracy but also reduces measurement errors caused by installation position deviations. The movable locating pin can be adjusted according to different vehicle models or the dimensions of the rear quarter window assembly, further enhancing the versatility and adaptability of the inspection fixture.

[0028] In some embodiments of this application, the rack is further provided with a drawer, which stores a spare upper simulation block.

[0029] A drawer is installed on the rack to store spare upper simulation blocks. This design not only facilitates quick module replacement by operators but also improves the maintenance efficiency of the fixture. The storage of spare modules allows the fixture to be quickly restored to use in case of partial damage or replacement, reducing equipment downtime. Furthermore, the drawer design provides a neat storage space for the fixture, preventing module loss or damage, further extending the fixture's lifespan and cost-effectiveness.

[0038] The present application will now be described in detail with reference to the accompanying drawings.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] Rear quarter window assembly matching fixture, as in Example 1 Figure 1 , Figure 2 As shown: The system includes a frame 1, on which a base plate 2 is vertically mounted. A base 3 is fixedly mounted on the base plate 2. The base 3 has an outer frame structure, and its top surface forms a lower simulation seat 4. Several mounting seats 5 are arranged on the outer periphery of the base 3. An upper simulation block 6 is detachably mounted on each mounting seat 5. By replacing the upper simulation block 6 with different specifications, it can adapt to different vehicle models or rear quarter window assemblies of different shapes, exhibiting good versatility and expandability. Furthermore, damaged modules can be replaced individually after localized wear. This not only reduces equipment costs for enterprises but also extends the service life of the inspection tool.

[0041] All the upper simulation blocks 6 are assembled to form the upper simulation seat, and the outer edge of the rear quarter window assembly to be inspected is installed between the upper simulation seat and the lower simulation seat 4. The lower simulation seat 4 is constructed through the outer frame of the base 3, which, together with the upper simulation seat composed of the detachable upper simulation blocks 6, forms a complete clamping structure, accurately simulating the installation boundary conditions of the rear quarter window on the side of the vehicle body. This dual-layer simulation structure can completely restore the mating surface contour of the vehicle body sheet metal parts, solving the detection distortion problem caused by traditional inspection tools that only simulate one side of the contact surface.

[0042] Example 2, as Figures 1 to 5 As shown, the base 3 is composed of multiple base blocks 8, each corresponding to a mounting base 5. Preferably, the base blocks 8 and the mounting base 5 are integrally formed. By fixing the relative positions of the mounting base 5 and the base blocks 8, the relative positions of the upper module and the base blocks 8 are ensured.

[0043] The modular design allows the base 3 to be flexibly adjusted and assembled according to the dimensions of different vehicle models or rear quarter window assemblies. This structure not only improves the versatility and adaptability of the fixture, but also facilitates the quick replacement of damaged base blocks 8 in case of partial damage, reducing maintenance costs and equipment downtime. In addition, the modular design of the base 3 also facilitates transportation and storage, further enhancing the practicality and economy of the fixture.

[0044] One side of the upper simulation block 6 extends outward to form a mounting block 9, which is placed above the mounting base 5, with its bottom surface abutting against the top surface of the mounting base 5. This enables rapid positioning and installation of the upper simulation block 6. The extended structure of the mounting block 9 not only provides additional support area and enhances connection stability but also simplifies the installation process and improves operational efficiency. Furthermore, the fitting design between the mounting block 9 and the mounting base 5 effectively transmits force and torque, ensuring a tight fit between the upper simulation block 6 and the base 3 during testing, thereby improving testing accuracy and repeatability.

[0045] The mounting base 5 is provided with a positioning hole 10 and two insertion holes 11, with the two insertion holes 11 located on both sides of the positioning hole 10. The positioning hole 10 and insertion holes 11 on the mounting base 5 provide a precise positioning and fixing method for the upper simulation block 6. This dual positioning and fixing method not only improves the accuracy and stability of the installation but also enhances the overall rigidity of the structure, reducing detection deviations caused by installation errors. At the same time, this design also facilitates quick disassembly and replacement of the upper simulation block 6, improving the versatility and maintenance efficiency of the fixture.

[0046] A locking element 12 is installed on the mounting block 9, and two pins 13 are provided on the mounting block 9. The bottom of the locking element 12 and the bottom of the pins 13 protrude from the mounting block 9. When the mounting block 9 is stacked on top of the mounting base 5, the two pins 13 correspond one-to-one with the two insertion holes 11, with the bottom of the pins 13 inserted into the insertion holes 11, and the bottom of the locking element 12 extending into the positioning hole 10. Through the design of the locking element 12 and the pins 13, the upper simulation block 6 is firmly fixed on the mounting base 5. The bottom of the locking element 12 extending into the positioning hole 10 provides vertical fixing force, while the pins 13 inserted into the insertion holes 11 provide horizontal constraint. This dual fixing method ensures the stability of the upper simulation block 6 during the inspection process and avoids loosening due to vibration or external force. At the same time, the combined design of the locking element 12 and the pins 13 simplifies the installation and disassembly process, improves operating efficiency, and further enhances the practicality and reliability of the inspection tool.

[0047] The locking member 12 consists of a cap 14, a rod 15, and a locking part 16 from top to bottom. The outer diameter of the cap 14 is larger than that of the rod 15, and the outer diameter of the locking part 16 is larger than that of the rod 15. The locking part 16 passes through the mounting block 9 and locks into the positioning hole 10. The cap 14 provides a gripping part for easy operation, the rod 15 is used for connection and force transmission, and the locking part 16 achieves a firm fixation through its cooperation with the positioning hole 10. Simultaneously, the segmented structure makes the locking member 12 easier to install and remove, reducing operational difficulty. Furthermore, the tight fit between the locking part 16 and the positioning hole 10 effectively prevents loosening, ensuring the stability of the upper simulation block 6 during testing, thereby improving testing accuracy and reliability. Specifically, this application can configure the locking part 16 and the positioning hole 10 to achieve locking through an interference fit, or it can configure the locking part 16 and the positioning hole 10 to achieve locking through a threaded connection.

[0048] The mounting block 9 has a stepped hole, including a main hole 18 and a secondary hole 19. The secondary hole 19 is located above the main hole 18 and is adapted to the size of the rod 15. The diameter of the main hole 18 is greater than or equal to the outer diameter of the locking part 16. The locking part 16 can be housed in the main hole 18 or extend out of the main hole 18 to connect with the positioning hole 10. A spring 20 is sleeved on the screw located above the mounting block 9. The stepped hole design provides flexible installation and storage space for the locking part 12. The secondary hole 19 is adapted to the size of the rod 15 to ensure the positioning accuracy of the locking part 12 during installation; while the larger diameter of the main hole 18 allows sufficient space for the locking part 16 to be stored, avoiding installation difficulties caused by size limitations. This design not only improves the efficiency of installation and disassembly, but also provides cushioning for the locking part 12 through the elasticity of the spring 20, reducing damage caused by impact or vibration. Meanwhile, the stepped hole design makes the installation of the locking component 12 more stable, further improving the reliability and accuracy of the testing process.

[0049] The base 3 is provided with several testing seats 21. A dial indicator seat 22 is rotatably mounted on each testing seat 21. Each dial indicator seat 22 has at least one dial indicator hole 23 located above the rear triangular window assembly to be tested. The dial indicator hole is equipped with a dial indicator. This design, through the rotatable dial indicator seat 22 and dial indicator hole 23, provides more convenient installation space for the rear triangular window assembly to be tested. The dial indicator hole 23, located above the rear triangular window assembly, ensures the accuracy and consistency of the measurement points. This design not only improves the flexibility and adaptability of the testing but also reduces errors caused by inaccurate measurement positions, further improving the reliability of the test results.

[0050] One of the mounting bases 5 is equipped with a movable positioning pin 24, one end of which extends between the upper and lower simulated bases 4. The movable positioning pin 24 provides a precise positioning reference for the installation of the rear quarter window assembly. The pin's insertion between the upper and lower simulated bases 4 effectively constrains the position of the rear quarter window assembly, ensuring its stability during inspection. This design not only improves inspection accuracy but also reduces measurement errors caused by installation position deviations. The movable positioning pin 24 can be adjusted according to different vehicle models or the dimensions of the rear quarter window assembly, further enhancing the versatility and adaptability of the inspection fixture.

[0051] The frame 1 is also equipped with a drawer 25, which stores spare upper simulation blocks 6. This design, with drawer 25 for storing spare upper simulation blocks 6, not only facilitates quick module replacement by operators but also improves the maintenance efficiency of the fixture. The storage of spare modules allows the fixture to be quickly restored to use in case of partial damage or replacement, reducing equipment downtime. Furthermore, the drawer 25 provides a neat storage space for the fixture, preventing module loss or damage, further extending the fixture's lifespan and cost-effectiveness.
