Description

Technical Field

[0001] The invention relates to the technical field of laser detection platforms, in particular to an adjustable laser detection platform for automobile shock absorbers. Background Art

[0002] The laser testing bench is a high-tech testing equipment. The testing method is non-contact and will not cause physical damage to the shock absorber. Laser testing can achieve micron-level measurement accuracy, which is very suitable for high-precision automotive parts testing. It is used for accurate measurement and analysis of automotive shock absorbers. First, the actual working conditions of the shock absorber are simulated, and then the laser displacement sensor continuously monitors the displacement changes of the shock absorber and records the data. The data is processed using analysis software to analyze whether there are abnormal fluctuations and the frequency components of the displacement data to identify structural changes caused by fatigue. Finally, fatigue assessment is performed. The laser displacement sensor is used to monitor the displacement changes of the shock absorber during the fatigue test to evaluate its durability and reliability during continuous use.

[0003] When using a laser testing platform to test automobile shock absorbers, the size and shape of automobile shock absorbers vary depending on the model, purpose and design. In addition, the upper and lower ends of the shock absorbers have round holes for mounting the shock absorbers on the automobile and used in conjunction with bolts. The diameters of the round holes may also be different due to different models and designs of shock absorbers. This will cause trouble for the laser testing platform to fix the automobile shock absorbers when testing with the laser testing platform. Therefore, the laser testing platform is required to have the ability to test shock absorbers of different sizes to ensure that it can serve various types of automobile shock absorbers. For this purpose, an adjustable laser testing platform for automobile shock absorbers is designed. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 12 , the present invention provides a technical solution.

[0033] An adjustable laser detection platform for automobile shock absorbers, comprising a positioning cross bar 8, the front and rear ends of the positioning cross bar 8 are slidably connected with a position adjustment clamping plate 10, one end of each position adjustment clamping plate 10 is rotatably connected with an adjustment linkage frame 14, the surface of each adjustment linkage frame 14 is rotatably connected with a fixed point clamping plate 19, the surface of the fixed point clamping plate 19 is fixedly connected with an adjustment slider 18, the surface of the adjustment linkage frame 14 is provided with an adjustment slideway 17 for horizontal movement of the adjustment slider 18, the surface of each adjustment linkage frame 14 is rotatably connected with a threaded adjustment rod 12, the surface of the fixed point clamping plate 19 is provided with a second threaded hole 25 The second threaded hole 25 is threadedly connected, and the moving range of the adjusting slider 18 along the adjusting slide 17 can be used to separate the fixed-point clamping plate 19 from the threaded adjusting rod 12. By setting the adjusting clamping plate 10, the adjusting linkage frame 14 and the fixed-point clamping plate 19, when facing shock absorbers 35 of different sizes, the position of the fixed-point clamping plate 19 on the surface of the adjusting linkage frame 14 is adjusted to adapt, which is conducive to the detection of the clamping and fixing of shock absorbers 35 of different sizes. By setting the positioning cross bar 8, the positioning cross bar 8 passes through the circular hole at the end of the shock absorber 35, and the displacement of the positioning cross bar 8 can be measured, so that the displacement of the end of the shock absorber 35 during the test can be obtained.

[0034] There are two threaded adjustment rods 12 on each adjustment linkage frame 14, which are symmetrically arranged on the upper and lower sides of the adjustment linkage frame 14. By arranging two threaded adjustment rods 12, the fixed-point clamping plate 19 is more stable when moved by the threaded adjustment rods 12, and is also more stable when clamped; the surface of the adjustment linkage frame 14 is rotatably connected to a driving gear 16, and the surface of each threaded adjustment rod 12 is coaxially fixedly connected to a driven gear 15, and the driving gear 16 is meshed with each driven gear 15. Through such an arrangement, only one of the driven gear 15 and the driving gear 16 needs to be rotated to make the two threaded adjustment rods 12 rotate at the same time, which is convenient to operate.

[0035] One end of each threaded adjustment rod 12 is coaxially fixedly connected to a limiting disc 13, and the surface of the adjustment clamping plate 10 is provided with a T-shaped arc groove 11 for the threaded adjustment rod 12 and the limiting disc 13 to rotate, and the T-shaped arc groove 11 can be used for the threaded adjustment rod 12 to rotate. By setting the limiting disc 13, the threaded adjustment rod 12 is connected to the adjustment clamping plate 10. After the fixed-point clamping plate 19 contacts the end of the shock absorber 35, when the threaded adjustment rod 12 continues to rotate, the threaded adjustment rod 12 will have a tendency to move toward the fixed-point clamping plate 19 after the fixed-point clamping plate 19 cannot move due to the relativity of displacement, and the threaded adjustment rod 12 will have a tendency to move toward the fixed-point clamping plate 19, which will drive the adjustment clamping plate 10 to have a tendency to move toward the fixed-point clamping plate 19. The greater the rotation angle of the threaded adjustment rod 12, the tighter the fixed-point clamping plate 19 and the adjustment clamping plate 10 will be, which is conducive to fixing the adjustment clamping plate 10 and preventing the adjustment clamping plate 10 from sliding on the surface of the positioning cross bar 8.

[0036] The surface of each adjusting clamping plate 10 is fixedly connected with a U-shaped slide plate 9, and the surface of the positioning cross bar 8 is cooperated with a U-shaped slide groove 7 for the U-shaped slide plate 9 to slide. By setting the adjusting clamping plate 10, the surface of the positioning cross bar 8 can be slid on the surface of the positioning cross bar 8, which is conducive to adjusting the position of the adjusting clamping plate 10 according to the size of the shock absorber 35. If the round hole at the end of the shock absorber 35 is enough for the positioning cross bar 8, the adjusting clamping plate 10, the adjustment linkage frame 14, and the fixed point clamping plate 19 to all pass through, they can be passed through directly. If the round hole at the end of the shock absorber 35 is only enough for the positioning cross bar 8 to pass through, the adjusting clamping plate 10 can be moved first, so that the adjusting clamping plate 10 does not need to pass through the shock absorber 35 and the shock absorber 35 can be fixed.

[0037] The detection table 1 also includes a detection table 1, in which a telescopic pump is installed. The detection table 1 is installed with a test rod 2 which can move up and down through the telescopic pump. The top of the test rod 2 is fixedly connected to a support frame 3, and the left and right ends of the support frame 3 are fixedly connected to side frames 4. The surface of the side frame 4 is slidably connected to a positioning plate 6, and a U-shaped slide groove 7 is provided for the positioning plate 6 to be embedded. By placing a positioning cross bar 8 on two side frames 4 and then moving the positioning plate 6 to be embedded in the U-shaped slide groove 7 to fix the positioning cross bar 8, the telescopic pump can be started to drive the test rod 2 to move up and down to perform fatigue testing on the shock absorber 35.

[0038] The surface of the side frame 4 is threadedly connected with a first bolt 5, one end of which is in contact with a positioning plug plate 6. By rotating the first bolt 5, the first bolt 5 will move horizontally, and the positioning plug plate 6 will be pushed and embedded in the U-shaped slide groove 7 through the horizontal movement of the first bolt 5.

[0039] A support column 31 is fixedly connected to the top of the detection table 1, and a connecting rod 30 that can move up and down is slidably connected to the surface of the support column 31. One end of the connecting rod 30 is connected to a mounting plate 27, and one end of the mounting plate 27 is connected to a connecting frame 28. A laser detector 29 is installed on the surface of the connecting frame 28. The laser detector 29 can be rotatably connected to the connecting frame 28. A motor is installed on the surface of the connecting frame 28, and the rotation of the laser detector 29 is controlled by the motor. After the shock absorber 35 is fixed, the angle of the laser detector 29 is adjusted to face the positioning cross bar 8, and the displacement of the positioning cross bar 8 moving up and down is recorded, which can record the displacement of one end of the shock absorber 35.

[0040] The surface of the support column 31 is provided with a sliding groove for the connecting rod 30 to move up and down. The internal rotation of the support column 31 is connected to a vertically arranged threaded rod 32. The threaded rod 32 movably penetrates the surface of the connecting rod 30, and the threaded rod 32 and the connecting rod 30 are threadedly connected. The internal rotation of the support column 31 is connected to a first gear 33, and the surface of the support column 31 is connected to a second gear 34. The threaded rod 32 and the first gear 33 are coaxially fixedly connected, and the second gear 34 and the first gear 33 are meshed. The specific implementation method of the connecting rod 30 moving up and down on the surface of the support column 31 is that rotating the second gear 34 drives the first gear 33 to rotate, and rotating the first gear 33 drives the threaded rod 32 to rotate. Since the connecting rod 30 and the threaded rod 32 are threadedly connected, the rotation of the threaded rod 32 can make the connecting rod 30 move up and down along the surface of the threaded rod 32.

[0041] The right end of the positioning cross bar 8 is fixedly connected to a guide sleeve rod 26, which has an insertion groove for the mounting plate 27 to be embedded in. The insertion groove also has a space for the end of the shock absorber 35 to move up and down after the mounting plate 27 is inserted into the insertion groove. After the shock absorber 35 is fixed by using the positioning cross bar 8, the adjustment clamping plate 10, the adjustment linkage frame 14, and the fixed point clamping plate 19, the guide sleeve rod 26 is sleeved on the surface of the mounting plate 27 by using the insertion groove, which can not only limit the alignment of the laser detector 29 with the positioning cross bar 8, but also prevent the positioning cross bar 8 from deviating from the moving trajectory when moving up and down.

[0042] The device further comprises a shock absorber 35 , and the upper and lower ends of the shock absorber 35 are provided with circular holes for installation.

[0043] The surface of the fixed-point clamping plate 19 is connected to a reinforcement plate 21 that can slide back and forth. The surface of the fixed-point clamping plate 19 is provided with an auxiliary slide groove 20 for the reinforcement plate 21 to slide back and forth. The surface of the fixed-point clamping plate 19 is provided with a first threaded hole 22, and the first threaded hole 22 is connected to the auxiliary slide groove 20. The first threaded hole 22 is internally threaded with a second bolt 23, and one end of the second bolt 23 contacts the reinforcement plate 21. The surface of the reinforcement plate 21 is provided with an anti-skid pad 24. When the fixed-point clamping plate 19 clamps the surface of the shock absorber 35, the second bolt 23 is rotated to push the reinforcement plate 21 to move along the track of the auxiliary slide groove 20 until the anti-skid pad 24 contacts the end of the shock absorber 35, thereby increasing the friction with the end of the shock absorber 35 and making the clamping more stable.

[0044] The specific scheme is as follows: Example 1, when the circular hole at the end of the shock absorber 35 is enough for the positioning cross bar 8, the position adjustment clamping plate 10, the adjustment linkage frame 14, and the fixed point clamping plate 19 to pass through all of them, first take out the shock absorber 35, and then pass the positioning cross bar 8, the position adjustment clamping plate 10, the adjustment linkage frame 14, and the fixed point clamping plate 19 from the right end of the shock absorber 35 through the circular hole at the lower end of the shock absorber 35, and then rotate the adjustment linkage frame 14 so that the adjustment linkage frame 14 is perpendicular to the position adjustment clamping plate 10, and then rotate the fixed point clamping plate 19 so that The fixed-point clamping plate 19 is perpendicular to the adjustment linkage frame 14, and then the fixed-point clamping plate 19 is pushed to move the fixed-point clamping plate 19 toward the direction of the shock absorber 35, so that the adjustment slider 18 moves along the track of the adjustment slide 17. During the movement of the fixed-point clamping plate 19, when the threaded adjustment rod 12 contacts the second threaded hole 25, the threaded adjustment rod 12 is driven to rotate by rotating the driving gear 16 or the driven gear 15, so that the threaded adjustment rod 12 passes through the second threaded hole 25 and moves along the surface of the threaded adjustment rod 12. Move until the fixed-point clamping plate 19 contacts the end of the shock absorber 35 and is clamped and fixed, then fix the upper end of the shock absorber 35 in the same structure and manner, then connect the guide sleeve rod 26 to the mounting plate 27, so that the guide sleeve rod 26 covers the end of the mounting plate 27, and finally place the positioning cross bar 8 on the side frame 4, and push the positioning plug plate 6 to move by rotating the first bolt 5 until the positioning plug plate 6 is embedded in the U-shaped slide groove 7 to fix the positioning cross bar 8. During the above operation, the positioning plug plate 6 and the positioning clamp The holding plate 10, the adjusting linkage frame 14, and the fixed-point clamping plate 19 are two symmetrical groups, which are operated synchronously and symmetrically. By starting the telescopic pump, the test rod 2 is driven to move up and down. The up and down movement of the test rod 2 will synchronously drive the support frame 3, the side frame 4, the positioning cross bar 8, and one end of the shock absorber 35 connected and fixed by the positioning cross bar 8 to move up and down. The shock absorber 35 is fatigue tested. The laser detector 29 emits a laser toward the positioning cross bar 8 to test the distance of each up and down movement of the positioning cross bar 8 to record data;

[0045] Embodiment 2 is performed when the circular hole at the end of the shock absorber 35 is only large enough for the positioning cross bar 8 to pass through. First, take out the shock absorber 35, slide the adjustment clamping plate 10, and move the U-shaped slide plate 9 along the track of the U-shaped slide groove 7. Then, only pass the positioning cross bar 8 from the right end of the shock absorber 35 through the circular hole at the end of the shock absorber 35. Then, rotate the adjustment linkage frame 14 so that the adjustment linkage frame 14 is perpendicular to the adjustment clamping plate 10, and then rotate the fixed point clamping plate 19 so that the fixed point clamping plate 19 is perpendicular to the adjustment linkage frame 14. The subsequent operations are the same as those in Embodiment 1.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
