Description

Technical Field

[0001] This utility model belongs to the field of shock absorber inspection equipment, specifically relating to a universal quick-change inspection tool for shock absorber assembly installation. Background Technology

[0002] The externally connected strut assembly of the shock absorber has a relative positional relationship during vehicle installation, such as the relative angle between the bracket opening and the upper support bolt. If the angle exceeds the set tolerance, it will cause installation difficulties or even make installation impossible, especially when supplying OEMs. Typically, OEMs first mount the lower end of the shock absorber on the chassis, and the upper bolt of the shock absorber is raised with the vehicle chassis to align with the mounting holes on the body. If the angle is out of tolerance, it will cause installation failure and serious production line stoppage. Therefore, the externally connected strut assembly of the shock absorber needs to pass 100% inspection to ensure that the installation angle is correct. The prior art provides a patent application with application number 201910688876.2, which discloses a component assembly angle detection gauge based on a shock absorber. It includes a base plate, on which a first measuring plate, a second measuring plate, and a third measuring plate are arranged sequentially from left to right. The upper end of the first measuring plate is open, and three measuring slots are provided at the opening. These three measuring slots correspond to three bolts on the outer connecting sleeve assembly of the shock absorber strut assembly, and the measuring slots are used to place the bolts. When the height of the measuring column is at the same height as the center of the oil reservoir and the outer connecting sleeve assembly, the center height of the mounting hole of the bracket on it is consistent. This device has a simple structure; it does not have a complicated structure and can directly place the shock absorber strut assembly for detection, making operation simpler. However, the prior art cannot be adjusted according to different specifications of shock absorbers. The length dimensions of products in the same series vary greatly. If a gauge is provided for each specification, the cost is too high, the space occupied is large, and the maintenance and regular upkeep increase the workload. Furthermore, because the left and right shock absorber structures are symmetrical, the prior art cannot be applied to shock absorber assemblies with opposite structures. If the gauges are made separately for the left and right sides, the manufacturing cost is high. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a universal quick-change inspection tool for shock absorber assembly installation, which effectively solves the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A universal quick-change inspection tool for shock absorber assemblies includes an inspection tool and a shock absorber assembly placed on the upper side of the inspection tool. The inspection tool includes a base plate, and a detachable bearing support block and a detection fixing block are slidably connected to one side of the upper end of the base plate.

Detailed Implementation

[0022] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1-10As shown, this utility model provides a universal quick-change inspection tool for shock absorber assemblies, including an inspection tool 1 and a shock absorber assembly 2 placed on the upper side of the inspection tool 1. The inspection tool 1 includes a base plate, and a detachable bearing support block 7 and a detection fixing block 4 are slidably connected to one side of the upper end of the base plate. The bearing support block 7 and the detection fixing block 4 can move along the length of the base plate. A detachable angle detection block 3 is installed on the upper side of the detection fixing block 4. The surface of the angle detection block has detection holes 16, which mimic the mounting holes of the vehicle body, for corresponding to the bolts of the shock absorber assembly 2 to check whether the bolt position of the shock absorber assembly 2 is accurate. One end of the detection fixing block 4 is equipped with a fixing member to fix the angle detection block 3. After loosening the fixing member to fix the angle detection, the angle detection block 3 can be removed. Because the two shock absorber assemblies 2 at the bottom of the vehicle are symmetrically arranged, the angle detection block 3 can be rotated 180 degrees during use to change the angle detection surface, allowing the other shock absorber assembly 2 to be tested. This achieves the effect of positioning and testing the two symmetrically arranged shock absorber assemblies 2 with one gauge 1. Furthermore, since the lengths of shock absorber assemblies 2 in the same series are different, in order to improve the applicability of the gauge 1, the bearing support block 7 used to support the shock absorber assembly 2 can be moved along the length direction at the upper end of the base plate and adjusted according to the length of the shock absorber assembly 2. Similarly, the position of the detection fixing block 4 can be adjusted according to the length of the shock absorber assembly 2, so that the position of the angle detection block 3 can be adjusted according to the length of the shock absorber assembly 2, making it convenient to use shock absorber assemblies 2 of different lengths.

[0024] To facilitate the disassembly and replacement of the detection fixing block 4, two guide rails 5 are fixedly connected to one side of the upper end of the base plate, and sliders 6 are fixedly connected to both sides of the lower end of the detection fixing block 4. The sliders 6 are slidably connected to the corresponding guide rails 5, and can move on the surface of the guide rails 5, thereby moving the detection fixing block 4. There are no obstructions at both ends of the guide rails 5, and the sliders 6 can be installed from one end of the guide rails 5 and removed from the other end of the guide rails 5, which facilitates the disassembly of the detection fixing block 4. Furthermore, multiple positioning holes are opened along the length direction at the upper end of the guide rails 5. The positioning holes penetrate the bottom of the base plate, and positioning pins can be inserted into the inside of the positioning holes to limit the detection fixing block 4. The detection fixing block 4 can be moved by pulling out the positioning pins, thus enabling the disassembly and installation of the detection fixing block 4.

[0025] Furthermore, to ensure that the bearing support block 7 and the angle detection block 3 are kept in the center position of the base plate during installation and are collinear with the axis of the shock absorber assembly 2, thus guaranteeing the accuracy of the shock absorber assembly 2 testing, a positioning block 8 is fixedly connected to the centerline position at the upper end of the base plate along the length of the base plate. A first positioning groove 9 and a third positioning groove 17 are respectively formed at the middle position of the bearing support block 7 and the detection fixing block 4 along the length of the positioning block 8. The positioning block 8 slides with the first positioning groove 9 and the third positioning groove 17 respectively. Through the corresponding sliding engagement of the first positioning groove 9 and the third positioning groove 17 with the positioning block 8, the bearing support block 7 and the detection fixing block 4 are kept in the center position of the base plate. This ensures that when the detection fixing block 4 is installed, it aligns with the bearing support block 7, facilitating the testing of the shock absorber assembly 2 and guaranteeing the accuracy of the testing.

[0026] Furthermore, to improve the stability of the bearing support block 7 during use, waist-shaped grooves 10 are respectively opened on the left and right sides of the upper surface of the bearing support block 7, and first threaded holes corresponding to the waist-shaped grooves 10 are respectively opened on the surface of the bottom plate. Positioning bolts are respectively provided on the inner side of the waist-shaped grooves 10, and the lower ends of the positioning bolts are respectively threadedly connected to the corresponding first threaded holes. By rotating the positioning bolts, the positioning bolts can be moved downwards to press the bearing support block 7 under the action of threaded connection between the positioning bolts and the first threaded holes, thereby fixing the bearing support block 7. When it is necessary to move the bearing support block 7, the positioning bolts can be rotated in the opposite direction to loosen the fixing of the bearing support block 7, and then the bearing support block 7 can be moved and adjusted according to the length of the shock absorber assembly 2.

[0027] Furthermore, in order to ensure that the angle detection block 3 is installed parallel to the base plate and that the angle detection block 3 can accurately correspond to the shock absorber assembly 2, the upper end of the detection fixing block 4 is provided with a horizontal groove 13. The horizontal groove 13 is parallel to the width direction of the base plate. The angle detection block 3 is installed inside the horizontal groove 13 so that the detection surface of the angle detection block 3 can correspond to the shock absorber assembly 2, thereby achieving accurate detection of the shock absorber assembly 2. The fixing component includes fixing bolts 14. The left and right sides of the front end of the fixing block 4 are respectively provided with second threaded holes. The second threaded holes penetrate into the inner side of the transverse groove 13. The fixing bolts 14 are threadedly connected to the second threaded holes respectively. By rotating the fixing bolts 14, the fixing bolts 14 press against the angle detection block 3 to fix the angle detection block 3. By reversing the fixing bolts 14, the pressure on the angle detection block 3 is released, and the angle detection block 3 can be released, making it convenient to disassemble the angle detection block 3.

[0028] Furthermore, to maintain the accuracy of the angle detection block 3 during installation, a placement groove 12 is provided at the upper middle position of the detection fixing block 4 along the length of the base plate. A positioning key 11 is fixedly connected to the inner side of the placement groove 12. The positioning key 11 is located at the center line of the base plate. A second positioning groove 15 is provided at the lower middle part of the angle detection block 3. The second positioning groove 15 slides with the positioning key 11. With the cooperation of the second positioning groove 15 and the positioning key 11, the installation and positioning of the angle detection block 3 are further improved, so that the center of the angle detection block 3 corresponds to the center of the base plate. This ensures the detection accuracy of the angle detection block 3 for the shock absorber assembly 2 and facilitates installation by the user. It avoids frequent adjustments during the installation process and further improves the effectiveness of this inspection tool 1.
