Description

Technical Field

[0001] This application relates to the field of automotive component testing technology, and in particular to an inspection tool for automotive rear suspension assembly. Background Technology

[0002] As a key elastic component connecting the powertrain to the vehicle body, the automotive powertrain mounting system plays a crucial role in supporting the weight of the powertrain, controlling its displacement, and damping the transmission of vibrations to the vehicle body. Within this system, the precision testing of the rear mounting assembly is particularly critical, as it mainly consists of the upper and lower rear mounting bodies.

[0003] Currently, the main method for inspecting rear suspension assemblies involves designing testing fixtures to clamp and fix the rear suspension assembly, and then using standard testing parts such as go / no-go gauges, testing pins, and measuring rulers to inspect the rear suspension assembly. Relevant existing technologies include Chinese patent application "Rear Suspension Lower Body Inspection Fixture and its Testing Method," publication number CN110823049A, which discloses a base with a positioning block and a clamping mechanism that restrict the vertical position of the rear suspension lower body. The positioning block has a positioning pin corresponding to the position of the connecting hole. The positioning block supports the core of the connecting hole on the rear suspension lower body, which is located vertically. The base also has a testing component for detecting the position and spacing of the two connecting arms of the bracket, the position of the welded nut, and the coaxiality of the welded nut hole axis and the mounting hole axis. The testing component includes a support fixed to the base, and a first fixing block that restricts the horizontal position of the rear suspension lower body.

[0004] The aforementioned patent application uses positioning pins and fixing blocks to position and detect the lower rear suspension assembly, which improves detection accuracy and ease of operation to some extent. However, the fixed structure of its detection components makes it impossible to adjust for different specifications or models of rear suspension assemblies, thus lacking flexibility.

[0005] In actual production, the specifications and designs of automotive parts are constantly being optimized and adjusted. Fixed inspection components are difficult to adapt to these changes, requiring the redesign and manufacture of inspection fixtures for different products, which increases production and time costs. Furthermore, when inspecting different models of rear suspension assemblies, fixed inspection components may not be accurately aligned, leading to inaccurate inspection results and affecting product quality control. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a rear suspension assembly inspection tool for automobiles, with adjustable inspection components that can adapt to rear suspension assemblies of different specifications.

[0007] The technical solution adopted in this application is: a rear suspension assembly inspection fixture for automobiles, including a base plate, on which a positioning block, a clamping mechanism and a detection component are provided. The rear suspension assembly to be inspected is mounted on the positioning block and fixed by the clamping mechanism. The detection component includes an adjusting component, a base, and reference blocks mounted on both sides of the base. The detection component is provided with a detection through hole, which penetrates the base and the two reference blocks. The outer surfaces of the two reference blocks form a reference surface that contacts the rear suspension assembly to be inspected. The reference blocks are movably connected to the base. The adjusting component drives the reference blocks to move relative to the base.

[0008] Compared with existing technologies, the advantages of this application are as follows: First, the cooperation between the positioning block and the clamping mechanism enables rapid positioning and fixation of the rear suspension assembly. This design simplifies the operation process, improves inspection efficiency, and allows inspection personnel to prepare for inspection work more quickly.

[0009] Secondly, the reference block in the inspection assembly is movably connected to the base and moved by an adjusting mechanism. This adjustability allows the fixture to adapt to different specifications of rear suspension assemblies, increasing its versatility and flexibility. It eliminates the need to redesign and manufacture fixtures for different products, saving production and time costs. Due to the adjustable design of the inspection assembly, when inspecting different specifications of rear suspension assemblies, only the position of the reference block needs to be adjusted via the adjusting mechanism, making operation simple and convenient. Simultaneously, this design facilitates routine maintenance and upkeep of the fixture, such as lubricating the moving parts, extending its service life.

[0010] Furthermore, the detection through-hole on the detection component penetrates the base and two reference blocks, and the outer surfaces of the two reference blocks form reference surfaces that contact the rear suspension assembly to be tested. The entire fixture consists of a base plate, positioning blocks, a clamping mechanism, and a detection component, with a compact and reasonable structure. The base plate serves as a fundamental support, ensuring the stable installation of each component; the reasonable layout of the positioning blocks and clamping mechanism allows the rear suspension assembly to be firmly fixed in position during the testing process, reducing detection errors caused by workpiece shaking; the ingenious design of the detection component, while achieving adjustability, also ensures its own structural stability, thereby improving the reliability and stability of the entire fixture during the testing process.

[0011] In some embodiments of this application, the base is generally in the shape of an inverted T-shape, with mounting blocks on both sides of the base, and the reference block is located between the mounting block and the base, and the reference block and the mounting block are movably connected.

[0012] The structural design of the base makes the entire detection assembly more stable, provides reliable support for the movement of the reference block, ensures the stability of the base during the detection process, and thus improves the accuracy of the detection.

[0013] In some embodiments of this application, a circular ring structure is provided on the outer side of the reference block, and the outer side of the circular ring structure contacts the rear suspension assembly to be tested. The outer side of the circular ring structure serves as a reference surface.

[0014] The circular ring structure ensures precise positioning during testing, improving the reliability of the test. At the same time, the outer surface of the circular ring structure serves as a reference surface, increasing the stability of the contact.

[0015] In some embodiments of this application, the detection component includes two parallel connecting rods that pass sequentially through the left mounting block, the left reference block, the base, the right reference block, and the right mounting block.

[0016] In this application, the entire detection assembly is connected by two parallel connecting rods, making the structure of the detection assembly more compact, ensuring the coordinated work between the components, improving the overall stability and reliability of the detection assembly, and facilitating the detection operation.

[0017] In some embodiments of this application, a gap exists between the mounting block and the reference block, and a spring is provided between the mounting block and the reference block. The spring is in a compressed state and applies a force to the reference block to adhere to the base. This design allows the reference block to fit tightly against the base, ensuring stability during testing. At the same time, the spring force can adapt to certain dimensional changes, increasing the flexibility of the inspection tool.

[0018] In some embodiments of this application, the mounting block has two grooves on the side facing the reference block, and two connecting rods correspond one-to-one with the two grooves. The connecting rods passing through the grooves are coaxially arranged with the grooves, and one end of the spring is located inside the groove, with the spring sleeved outside the connecting rod. This structure makes the spring installation more precise, ensures the direction of force transmission, and improves the stability and detection accuracy of the detection component.

[0019] In some embodiments of this application, slots are provided on both the left and right sides of the base, and protruding rods are provided on the inner side of the reference block. The protruding rods extend into the base through the slots. An adjusting member is installed on the base, passing between the two protruding rods. The adjusting member is operated to apply force to the protruding rods. This design makes the adjustment of the reference block more precise and allows for flexible adjustment of the reference block's position to meet the testing requirements of rear suspension assemblies of different specifications.

[0020] In some embodiments of this application, the adjusting member is threadedly connected to the base, and rotating the adjusting member changes the depth to which the adjusting member is inserted into the base. The threaded adjustment method is simple to operate, enables stepless adjustment, and precisely controls the position of the reference block, improving the adaptability and detection accuracy of the fixture.

[0021] In some embodiments of this application, the middle part of the adjusting member has a frustum-shaped structure, and the middle part of the adjusting member is in contact with the protruding rod. The end face of the protruding rod is an inclined surface adapted to the middle part of the adjusting member. Changing the insertion depth of the adjusting member into the base changes the distance between the two protruding rods, thereby changing the distance between the two reference blocks. This makes the adjustment more flexible, enables non-linear distance adjustment, better adapts to different specifications of rear suspension assemblies, and improves the versatility of the inspection fixture and the accuracy of the inspection.

[0022] In some embodiments of this application, the clamping mechanism is a quick-release clamp. The substrate of this application is equipped with standard inspection components such as go / no-go gauges, inspection pins, and inspection rulers to inspect the rear suspension assembly.

[0031] The present application will now be described in detail with reference to the accompanying drawings.

[0032] 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.

[0033] Automotive rear suspension assembly inspection fixture, Example 1 as follows Figure 1 , Figure 2 As shown, the device includes a base plate 1, on which a positioning block 2, a clamping mechanism 3, and a detection assembly are mounted. The rear suspension assembly to be tested is mounted on the positioning block 2 and fixed by the clamping mechanism 3. The cooperation between the positioning block 2 and the clamping mechanism 3 enables rapid positioning and fixation of the rear suspension assembly. This design simplifies the operation process, improves detection efficiency, and allows inspection personnel to prepare for inspection work more quickly.

[0034] The detection assembly includes an adjusting component 5, a base 6, and reference blocks 7 installed on both sides of the base 6. A detection through-hole 8 is provided on the detection assembly, penetrating the base 6 and the two reference blocks 7. The entire fixture consists of a base plate 1, positioning blocks 2, a clamping mechanism 3, and the detection assembly, with a compact and reasonable structure. The base plate 1 serves as a fundamental support, ensuring stable installation of all components. The reasonable layout of the positioning blocks 2 and the clamping mechanism 3 ensures that the rear suspension assembly can be firmly fixed in position during detection, reducing detection errors caused by workpiece movement. The ingenious design of the detection assembly, while achieving adjustability, also ensures its own structural stability, thereby improving the reliability and stability of the entire fixture during the detection process.

[0035] The outer surfaces of the two reference blocks 7 form reference surfaces that contact the rear suspension assembly to be inspected. The reference blocks 7 are movably connected to the base 6, and the adjusting element 5 drives the reference blocks 7 to move relative to the base 6. This adjustability allows the fixture to adapt to rear suspension assemblies of different specifications, increasing its versatility and flexibility. It eliminates the need to redesign and manufacture fixtures for different products, saving production and time costs. Due to the adjustable design of the inspection components, when inspecting rear suspension assemblies of different specifications, only the position of the reference blocks 7 needs to be adjusted via the adjusting element 5, making operation simple and convenient. Simultaneously, this design also facilitates routine maintenance and upkeep of the fixture, such as lubricating the moving parts, extending the fixture's service life.

[0036] The clamping mechanism 3 is a quick clamp. The base plate 1 of this application is equipped with standard inspection components such as go / no-go gauges, inspection pins, and inspection rulers to inspect the rear suspension assembly.

[0037] Example 2, as Figures 1 to 5As shown, the base 6 has an inverted T-shaped structure. Mounting blocks 9 are provided on both sides of the base 6, and the reference block 7 is located between the mounting blocks 9 and the base 6, with the reference block 7 movably connected to the mounting blocks 9. The structural design of the base 6 makes the entire detection assembly more stable, providing reliable support for the movement of the reference block 7 and ensuring the stability of the base 6 during the detection process, thereby improving the accuracy of the detection.

[0038] A circular ring structure 10 protrudes from the outer surface of the reference block 7. The outer surface of the circular ring structure 10 contacts the rear suspension assembly to be tested, and the outer surface of the circular ring structure 10 serves as a reference surface. The circular ring structure 10 ensures accurate positioning during testing, improves the reliability of testing, and at the same time, the outer surface of the circular ring structure 10, as a reference surface, increases the stability of contact.

[0039] The detection assembly includes two parallel connecting rods 11, which pass sequentially through the left mounting block 9, the left reference block 7, the base 6, the right reference block 7, and the right mounting block 9. In this application, the entire detection assembly is connected by the two parallel connecting rods 11, making the structure of the detection assembly more compact, ensuring the coordinated work between the components, improving the overall stability and reliability of the detection assembly, and facilitating the detection operation.

[0040] There is a gap between the mounting block 9 and the reference block 7. A spring 12 is provided between the mounting block 9 and the reference block 7. The spring 12 is in a compressed state and applies a force to the reference block 7 to adhere to the base 6. This design allows the reference block 7 to fit tightly against the base 6, ensuring stability during inspection. At the same time, the elastic force of the spring 12 can adapt to certain dimensional changes, increasing the flexibility of the inspection tool.

[0041] The mounting block 9 has two grooves 13 facing the reference block 7. Two connecting rods 11 correspond one-to-one with the two grooves 13. The connecting rods 11 passing through the grooves 13 are coaxially arranged with the grooves 13. One end of the spring 12 is located inside the groove 13, and the spring 12 is sleeved on the outside of the connecting rod 11. This structure makes the installation of the spring 12 more precise, ensures the direction of force transmission, and improves the stability and detection accuracy of the detection component.

[0042] The base 6 has slots 14 on both its left and right sides. The reference block 7 has protruding rods 15 on its inner side, which extend into the base 6 through the slots 14. An adjusting member 5 is mounted on the base 6, passing between the two protruding rods 15. Operating the adjusting member 5 applies force to the protruding rods 15. This design allows for more precise adjustment of the reference block 7, enabling flexible adjustment of its position to meet the testing requirements of rear suspension assemblies of different specifications.

[0043] The adjusting element 5 is threadedly connected to the base 6. Rotating the adjusting element 5 changes the depth to which it is inserted into the base 6. The threaded adjustment method is simple to operate, enables stepless adjustment, and precisely controls the position of the reference block 7, thereby improving the adaptability and detection accuracy of the fixture.

[0044] The adjusting member 5 has a frustum-shaped structure in the middle, which is in contact with the protruding rod 15. The end face of the protruding rod 15 is an inclined surface adapted to the middle of the adjusting member 5. Changing the insertion depth of the adjusting member 5 into the base 6 changes the distance between the two protruding rods 15, thereby changing the distance between the two reference blocks. This makes the adjustment more flexible, enabling non-linear distance adjustment, better adapting to different specifications of rear suspension assemblies, and improving the versatility and accuracy of the inspection fixture.
