Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber brackets, specifically a comprehensive inspection tool for automotive shock absorber brackets. Background Technology

[0002] The shock absorber bracket is a key component connecting the shock absorber to the vehicle body, crucial for improving vehicle handling, comfort, and safety. The bracket is connected to the body via bolts or welding, providing a stable mounting point for the shock absorber, ensuring its vertical movement and preventing performance degradation due to misalignment. When the wheels encounter bumps, the road reaction force is transmitted through the shock absorber to the bracket, and then distributed by the bracket to the vehicle body structure. A comprehensive inspection tool for automotive shock absorber brackets is a specialized tool used to accurately inspect key parameters such as the bracket's position and profile.

[0003] Traditional automotive shock absorber bracket inspection tools are not convenient for visually detecting the offset of automotive shock absorber brackets. If only the position and profile are checked without offset detection, when the bracket offset exceeds the standard, it will cause the shock absorber axis to be non-perpendicular to the vehicle body mounting surface, resulting in poor coaxiality between the piston and the working cylinder. Furthermore, the offset bracket will excite the suspension system to resonate, producing low-frequency humming or high-frequency vibration noise. During rapid acceleration, braking, steering, and other maneuvers, the bracket offset will change the dynamic stiffness of the shock absorber, affecting the vehicle's handling stability. Utility Model Content

[0018] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 4As shown, a comprehensive inspection tool for automotive shock absorber brackets includes a base plate 1, a support plate 2 fixedly connected to one side of the base plate 1, a detection plate 4 slidably connected to the support plate 2 through a first sliding groove 3, a drive mechanism 11 provided on one side of the support plate 2, a second mounting member 6 provided at the lower part of the detection plate 4, a first mounting member 5 provided at the upper part of the base plate 1 corresponding to the position of the second mounting member 6, and a detection mechanism 7 provided on the base plate 1. The detection mechanism 7 includes a sliding cavity 701 formed in the inner cavity of the base plate 1. The base plate 1 has a second sliding groove 702 communicating with the sliding cavity 701. Two transmission blocks 703 are symmetrically slidably connected to the inner wall of the sliding cavity 701. A first connecting block 704 and a second connecting block 705 are fixedly connected to both sides of the transmission blocks 703 and slidably disposed in the second sliding groove 702. An infrared emitter 706 is provided on the side of the first connecting block 704 facing the second connecting block 705. An infrared receiver 707 is provided on the second connecting block 705 at the position corresponding to the infrared emitter 706. A bidirectional screw 8 is rotatably connected in the sliding cavity 701. An adjusting handle 9 is fixedly connected to one end of the bidirectional screw 8. One side of each of the two transmission blocks 703 is threadedly connected to one side of the bidirectional screw 8. A first guide rod 10 is fixedly connected in the sliding cavity 701. The other side of each of the two transmission blocks 703 is slidably connected to one side of the first guide rod 10. In this comprehensive inspection fixture for automotive shock absorber brackets, the base plate 1 provides support, and the support plate 2 is fixedly connected to one side of the base plate 1, providing primary support for the drive mechanism 11 and the inspection plate 4. The shock absorber and its bracket are installed between the base plate 1 and the inspection plate 4 via the first mounting component 5 and the second mounting component 6. The drive mechanism 11 drives the inspection plate 4 to reciprocate up and down, pressing the shock absorber and its bracket. The inspection mechanism 7 can detect the offset of the shock absorber and its bracket. The bidirectional screw 8 can be considered a transmission component of the inspection mechanism 7, and can be adjusted via the adjusting handle 9. The bidirectional screw 8 is driven to rotate. Since the two transmission blocks 703 are threadedly connected to one side of the bidirectional screw 8, the rotation of the bidirectional screw 8 can drive the transmission blocks 703 to adjust the spacing. The infrared emitter 706 and the infrared receiver 707 can adapt to shock absorbers and shock absorber brackets of different sizes. The infrared emitter 706 and the infrared receiver 707 are aligned on the axis. The object obstruction is detected by the light path interruption. When the shock absorber and the shock absorber bracket are offset, the ray blocking is cut off. When the light signal is disconnected, this signal is converted into an electrical signal and transmitted to the detection instrument to record the offset.

[0020] like Figure 3As shown, the first mounting component 5 includes a first fixing plate 501 disposed on the base plate 1. The first fixing plate 501 is symmetrically provided with a first fixing hole 502 and a docking hole 503.

[0022] In one embodiment, such as Figure 4 and Figure 5 As shown, the drive mechanism 11 includes a motor 1101 fixedly installed on one side of the support plate 2. The output end of the motor 1101 is provided with a drive gear 1102. The support plate 2 is rotatably connected to a turntable 1103 on the other side of the motor 1101.

A connecting rod 1105 is eccentrically rotatably connected to the other side of the turntable 1103. The other end of the connecting rod 1105 is rotatably connected to the upper part of the detection plate 4. The motor 1101 in the drive mechanism 11 drives the drive gear 1102 to rotate, which drives the driven gear 1104 to rotate, causing the turntable 1103 to rotate. When the turntable 1103 rotates, it drives the connecting rod 1105 to swing back and forth, which in turn drives the detection plate 4 connected to the other end of the connecting rod 1105 to move up and down back and forth. During the back and forth movement of the detection plate 4, the shock absorber and the shock absorber bracket can be continuously squeezed to achieve the offset test.

[0023] like Figure 4 and Figure 5 As shown, a protective box 12 is provided on one side of the support plate 2, and the driving gear 1102 and the driven gear 1104 are both located in the inner cavity of the protective box 12; the protective box 12 can provide sealed protection for the driving gear 1102 and the driven gear 1104.

[0024] like Figure 2 and Figure 5 The bottom of the protective box 12 shown is fixedly connected to a second guide rod 13, and the other end of the second guide rod 13 is fixedly connected to the base plate 1. The detection plate 4 is slidably connected to the second guide rod 13. While the detection plate 4 slides along the first slide groove 3, the extension part of the detection plate 4 slides along the surface of the second guide rod 13, thereby improving the stability of the reciprocating lifting and lowering of the detection plate 4.

[0025] In another embodiment, the drive mechanism 11 includes a motor 1101 fixedly mounted on one side of the support plate 2. A turntable 1103 is rotatably connected to the support plate 2 on the other side of the motor 1101.

A connecting rod 1105 is eccentrically rotatably connected to the other side of the turntable 1103. The other end of the connecting rod 1105 is rotatably connected to the upper part of the detection plate 4. A second guide rod 13 is fixedly connected to the bottom of the motor 1101.
