Description

Technical Field

[0001] This utility model relates to the field of verticality detection technology, specifically to an air spring guide column verticality detection device. Background Technology

[0002] An air spring is a non-metallic spring that uses compressed air to achieve elasticity and is widely used in automobiles, rail transportation, and other fields. The air spring guide post is a crucial component of an air spring system. It limits the air spring's displacement outside the vertical direction (such as lateral or longitudinal offset), ensuring stable expansion and contraction along its axial direction and preventing abnormal wear or performance degradation caused by misalignment.

[0003] Insufficient perpendicularity of the air spring guide post will cause uneven contact force between the guide post and the guide sleeve during movement, increasing local friction and leading to rapid wear of the inner wall of the guide sleeve or the surface of the guide post, even resulting in scratches and jamming. This not only affects the service life of the air spring but also weakens its shock absorption effect. To address this, an air spring guide post perpendicularity testing device is proposed.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, an air spring guide column verticality testing device includes a workbench 1 and a dial indicator 15. A rotating disk 3 is rotatably connected to the upper end of the workbench 1. Two symmetrical clamping blocks 4 are suspended above the rotating disk 3. The ends of the two clamping blocks 4 that are close to each other are provided with arc surfaces. An adjustment mechanism acting on the clamping blocks 4 is provided on the rotating disk 3. A guide column 9 is also fixedly installed on the upper end of the workbench 1. A sleeve 10 is fitted on the outer wall of the guide column 9. A locking screw 11 is provided at one end of the sleeve 10, and the locking screw 11 penetrates the sleeve 10. On the side wall, a first locking screw 11 is threadedly connected to a sleeve 10. A guide rail 12 is fixedly connected to the other end of the sleeve 10. Multiple second locking screws 16 are provided on the upper end of the guide rail 12. The multiple second locking screws 16 are arranged in a linear array and are threadedly connected to the guide rail 12. A slider 13 is slidably installed inside the guide rail 12. A connecting block 14 is fixedly connected to the side wall of the slider 13. The sleeve of the dial indicator 15 slides through the connecting block 14. A third locking screw 17 is provided on the side of the connecting block 14 and is screwed into the inside of the connecting block 14.

[0021] The adjustment mechanism consists of a fixed vertical plate 5, a guide rod 6, a double-ended lead screw 7, and an adjustment component 8. The two fixed vertical plates 5 are distributed on the side of the two clamping blocks 4 that are far apart from each other. The fixed vertical plates 5 are fixedly connected to the rotating disk 3. The guide rod 6 is fixedly connected between the two fixed vertical plates 5. The guide rod 6 slides through the two clamping blocks 4. The double-ended lead screw 7 is also rotatably connected between the two fixed vertical plates 5. The two clamping blocks 4 are threaded onto the two ends of the double-ended lead screw 7. One end of the double-ended lead screw 7 passes through the fixed vertical plate 5 and is fixedly connected to the adjustment component 8.

[0022] Place the air spring guide post between the two clamping blocks 4, manually rotate the adjusting component 8 to drive the double-ended lead screw 7 to rotate, and control the two clamping blocks 4 to move closer to each other to clamp the air spring guide post.

[0023] Among them, the helix angle of the double-ended lead screw 7 is smaller than its friction angle.

[0024] This configuration ensures that the lead screw has self-locking properties, preventing the clamping block 4 from moving.

[0025] The bottom of the rotary disk 3 is fixedly connected to a connecting plate 19, which has a ring structure. The upper end of the worktable 1 is provided with a connecting groove 18, which is compatible with the connecting plate 19.

[0026] The rotating disk 3 can be rotatably connected to the worktable 1 by means of the connecting plate 19 and the connecting groove 18 with the ring structure.

[0027] Among them, an annular groove 20 is provided at the upper end of the rotating disk 3 near the edge.

[0028] The annular groove 20 creates an upward-protruding handle at the edge of the rotating disk 3, which the operator can grip to facilitate rotating the disk 3.

[0029] Two fixing plates 2 are fixedly connected to both ends of the workbench 1, and fixing holes are provided on the fixing plates 2.

[0030] The workbench 1 can be fixed in the installation position by using the fixed plate 2.

[0031] This utility model provides an air spring guide post verticality testing device, the specific working principle of which is as follows:

[0032] In use, pass the sleeve of the dial indicator 15 through the connecting block 14, then tighten the No. 3 locking screw 17. The No. 3 locking screw 17 can press against the outer wall of the sleeve of the dial indicator 15, thereby fixing the dial indicator 15 to the connecting block 14. Then, place the air spring guide post between the two clamping blocks 4, manually rotate the adjusting piece 8 to drive the double-ended lead screw 7 to rotate, control the two clamping blocks 4 to move closer to each other to clamp the air spring guide post, thereby fixing the air spring guide post at the rotation center of the rotating disk 3. The helix angle of the double-ended lead screw 7 is less than its friction angle, which can ensure that the lead screw has self-locking property and prevent movement after the clamping blocks 4 clamp the air spring guide post. Then loosen the No. 1 locking screw 11 so that the sleeve 10 can slide on the guide post 9. Move the sleeve 10 to the appropriate position, and then tighten the No. 1 locking screw 11. First, loosen the first locking screw 11, then loosen the second locking screw 16, and move the slider 13 so that the dial indicator 15's head contacts the outer wall of the air spring guide column. Then tighten the second locking screw 16 (since there are multiple second locking screws 16, there is always a second locking screw 16 to tighten no matter where the slider 13 is moved). Next, the operator manually rotates the rotating disk 3, causing the air spring guide column to rotate, so that the dial indicator 15's head can rotate around the air spring guide column for one revolution. Observe the swing range of the dial indicator 15's pointer, and record the maximum and minimum readings. Half of the difference between the maximum and minimum readings is the verticality deviation at that position. Then, following the above method, move the dial indicator 15 to different heights for testing to ensure the accuracy and comprehensiveness of the test results.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
