Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinder barrel testing technology, specifically relating to a hydraulic cylinder barrel impact resistance testing device. Background Technology

[0002] In the manufacturing process of hydraulic cylinder barrels, impact resistance is one of the key indicators for measuring their quality and service life. Therefore, conducting impact resistance testing on hydraulic cylinder barrels is an important step in ensuring their reliability.

[0003] Currently, existing hydraulic cylinder impact testing equipment suffers from numerous inconveniences in practical applications. On the one hand, to simulate the impact effects under different working conditions, it is often necessary to use pendulum heads of different shapes, such as flat, pointed, and curved, to conduct impact tests on the hydraulic cylinder. However, the pendulum heads of existing equipment are mostly fixed installation structures, and replacing pendulum heads of different shapes requires cumbersome disassembly and assembly operations. This not only consumes a lot of time but also easily affects the testing accuracy due to errors during the disassembly and assembly process, severely restricting the testing efficiency.

[0004] On the other hand, in the positioning stage before testing, existing equipment lacks convenient alignment aids. Testing personnel need to rely on visual observation or simple tools to repeatedly adjust the relative position of the pendulum head and the impact point of the hydraulic cylinder. This is not only time-consuming, but also makes it difficult to guarantee alignment accuracy, which further affects testing efficiency and the accuracy of results. Utility Model Content

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1 to 11As shown, the hydraulic cylinder impact testing equipment includes a base 1. A support frame 2 is fixedly connected to the upper surface of the base 1. A motor frame 3 is fixedly connected to the back of the support frame 2. A servo motor 4 is fixedly connected to the upper surface of the motor frame 3. A first rotating shaft 5 is fixedly connected to the output end of the servo motor 4. A clutch 6 is provided on the inner wall of the support frame 2. The driving end of the clutch 6 is fixedly connected to the end of the first rotating shaft 5. A second rotating shaft 7 is fixedly connected to the driven end of the clutch 6. A first connecting block 8 is fixedly connected to the surface of the second rotating shaft 7. A rectangular column 9 is fixedly connected to the right side of the first connecting block 8. A rectangular cylinder 10 is fitted onto the surface of the rectangular column 9. A flat pendulum head 11, a pointed pendulum head 12, and an arc-shaped pendulum head 13 are fixedly connected to the bottom of the rectangular cylinder 10. A rectangular hole 14 is opened on the upper surface of the rectangular cylinder 10. A rectangular box 15 is fitted into the inner wall of the rectangular hole 14. The rectangular box 15 is fixedly connected to the upper surface of the bottom rectangular column 9. The left and right sides of the rectangular box 15 are provided with first circular holes 16. The inner wall of the first circular hole 16 is fixedly connected with a first bearing 17. The inner ring of the first bearing 17 is fixedly connected with a threaded cylinder 18. The inner wall of the threaded cylinder 18 is threadedly connected with a threaded column 19. The left and right ends of the threaded column 19 and the upper surface of the rectangular cylinder 10 are fixedly connected with second connecting blocks 20. The surface of the threaded cylinder 18 is fixedly connected with a worm gear 21. The front and rear sides of the rectangular box 15 are provided with second circular holes 22. The inner wall of the second circular hole 22 is fixedly connected with a second bearing 23. The inner ring of the second bearing 23 is fixedly connected with a worm gear 24. The front of the worm gear 24 is fixedly connected with a rotating block 25. The upper surface of the base 1 is fixedly connected with a fixing mechanism 26. The upper surface of the base 1 is fixedly connected with a protective box 27. The front of the protective box 27 is hinged with a door 28.

[0033] The fixing mechanism 26 includes a mounting plate 261, a U-shaped plate 262, a slip ring 263, a trapezoidal block 264, and a hydraulic cylinder 265. The bottom of the mounting plate 261 is fixedly connected to the upper surface of the base 1, the upper surface of the mounting plate 261 is fixedly connected to the bottom of the U-shaped plate 262, the inner wall of the slip ring 263 is in contact with the surface of the U-shaped plate 262, the upper and lower ends of the hydraulic cylinder 265 are fixedly connected to the bottom of the slip ring 263 and the upper surface of the mounting plate 261, respectively, and the upper surface of the slip ring 263 is fixedly connected to the bottom of the trapezoidal block 264.

[0034] The planar pendulum head 11 is located to the left of the pointed pendulum head 12, and the arc-shaped pendulum head 13 is located to the right of the pointed pendulum head 12. The length of the rectangular hole 14 is greater than the length of the rectangular box 15, and the width of the rectangular hole 14 is equal to the width of the rectangular box 15.

[0035] It should be noted that the first rotating shaft 5 and the second rotating shaft 7 can be connected or disconnected through the clutch 6. When the first rotating shaft 5 and the second rotating shaft 7 are connected through the clutch 6, the planar pendulum head 11, the pointed pendulum head 12 and the arc-shaped pendulum head 13 can rotate counterclockwise through the servo motor 4. When the first rotating shaft 5 and the second rotating shaft 7 are disconnected through the clutch 6, the planar pendulum head 11, the pointed pendulum head 12 and the arc-shaped pendulum head 13 can automatically rotate clockwise through the gravity of the pendulum head 11.

[0036] The rectangular cylinder 10 can slide on the rectangular column 9. When the rotating block 25 rotates, the threaded cylinder 18 can rotate through the cooperation of the worm gear 21 and the worm 24. Through the cooperation of the threaded column 19 and the threaded cylinder 18, the distance between the planar pendulum head 11, the pointed pendulum head 12 and the arc-shaped pendulum head 13 and the first rotating shaft 5 can be changed. Thus, the shape of the pendulum head can be quickly switched during the detection of the hydraulic cylinder without disassembling the pendulum head, thereby effectively improving the detection efficiency.

[0037] When the cylinder barrel is placed on the slip ring 263, it can be positioned by the inclined surface on the trapezoidal block 264. At the same time, when the cylinder barrel on the slip ring 263 is brought into contact with the inner wall of the U-shaped plate 262 by the hydraulic cylinder 265, the cylinder barrel can be clamped by the trapezoidal block 264 and the U-shaped plate 262 and fixed on the slip ring 263. When the cylinder barrel is separated from the U-shaped plate 262, it can be directly removed from the slip ring 263.

[0038] The protective box 27 and the box door 28 are both made of aluminum alloy profiles and transparent tempered glass. The protective box 27 and the box door 28 can prevent the fragments generated when the cylinder barrel breaks from flying everywhere. The protective box 27 and the box door 28 can also isolate the flat pendulum head 11, the pointed pendulum head 12 and the arc pendulum head 13 from the operator, thereby improving the safety of the cylinder barrel impact resistance testing equipment.

[0039] like Figures 1 to 12 As shown, a slide rail 29 is fixedly connected to the upper surface of the base 1, a slider 30 is slidably connected to the surface of the slide rail 29, a mounting block 31 is fixedly connected to the upper surface of the slider 30, and a green laser pointer 32 is fixedly connected to the inner wall of the mounting block 31.

[0040] It should be noted that by setting a green laser pointer 32 on the base 1, the laser beam is used to indicate the position of the pendulum head, allowing the inspector to intuitively and quickly determine whether the impact point on the cylinder is aligned, thus greatly shortening the alignment operation time and improving the inspection efficiency. At the same time, through the cooperation of the slide rail 29 and the slider 30, the inspector can adjust the green laser pointer 32 to the appropriate position according to the different sizes of cylinders.

[0041] The working principle of this utility model is as follows: When the planar pendulum head 11 is needed for testing, the first rotating shaft 5 and the second rotating shaft 7 are first connected by the clutch 6. Then, the rectangular column 9 is rotated counterclockwise by the servo motor 4. Then, the worm 24 is rotated by rotating the rotating block 25. Then, the threaded cylinder 18 is rotated by the cooperation of the worm 24 and the worm wheel 21. And the planar pendulum head 11 is moved to a suitable position by the cooperation of the threaded cylinder 18 and the threaded column 19. Then, the cylinder is placed on the slip ring 263 and the trapezoidal block is used to move the cylinder. The inclined surface of 264 is used to position the cylinder barrel. Then, the cylinder barrel on the slip ring 263 is brought into contact with the inner wall of the U-shaped plate 262 by the hydraulic cylinder 265. At this time, the cylinder barrel can be clamped by the trapezoidal block 264 and the U-shaped plate 262 and fixed on the slip ring 263. Then, the first rotating shaft 5 is disconnected from the second rotating shaft 7 by the clutch 6. At this time, the plane pendulum head 11, the pointed pendulum head 12 and the arc pendulum head 13 are subjected to gravity, causing the plane pendulum head 11 to rotate automatically clockwise and impact the cylinder barrel.

[0042] When the pointed pendulum head 12 is needed for testing, the first rotating shaft 5 and the second rotating shaft 7 are first connected by the clutch 6. Then, the rectangular column 9 is rotated counterclockwise by the servo motor 4. Then, the worm 24 is rotated by rotating the rotating block 25. Then, the threaded cylinder 18 is rotated by the cooperation of the worm 24 and the worm wheel 21. And the pointed pendulum head 12 is moved to a suitable position by the cooperation of the threaded cylinder 18 and the threaded column 19. Then, the cylinder is placed on the slip ring 263 and the inclined surface of the trapezoidal block 264 is used to move the cylinder. The cylinder barrel is positioned, and then the cylinder barrel on the slip ring 263 is brought into contact with the inner wall of the U-shaped plate 262 by the hydraulic cylinder 265. At this time, the cylinder barrel can be clamped by the trapezoidal block 264 and the U-shaped plate 262 and fixed on the slip ring 263. Then, the first rotating shaft 5 is disconnected from the second rotating shaft 7 by the clutch 6. At this time, the weight of the flat pendulum head 11, the pointed pendulum head 12 and the arc-shaped pendulum head 13 causes the pointed pendulum head 12 to rotate automatically clockwise and impact the cylinder barrel.

[0043] When the arc-shaped pendulum head 13 is needed for testing, the first rotating shaft 5 and the second rotating shaft 7 are first connected by the clutch 6. Then, the rectangular column 9 is rotated counterclockwise by the servo motor 4. Then, the worm 24 is rotated by rotating the rotating block 25. Then, the threaded cylinder 18 is rotated by the cooperation of the worm 24 and the worm wheel 21. And the arc-shaped pendulum head 13 is moved to a suitable position by the cooperation of the threaded cylinder 18 and the threaded column 19. Then, the cylinder is placed on the slip ring 263 and the inclined surface of the trapezoidal block 264 is used to move the cylinder. The cylinder barrel is positioned, and then the cylinder barrel on the slip ring 263 is brought into contact with the inner wall of the U-shaped plate 262 by the hydraulic cylinder 265. At this time, the cylinder barrel can be clamped by the trapezoidal block 264 and the U-shaped plate 262 and fixed on the slip ring 263. Then, the first rotating shaft 5 is disconnected from the second rotating shaft 7 by the clutch 6. At this time, the arc-shaped pendulum head 13 is automatically rotated clockwise by the gravity of the planar pendulum head 11, the pointed pendulum head 12 and the arc-shaped pendulum head 13, and the arc-shaped pendulum head 13 impacts the cylinder barrel.

[0044] After the cylinder barrel is inspected, the first rotating shaft 5 is connected to the second rotating shaft 7 via the clutch 6. Then, the rectangular column 9 is rotated counterclockwise by the servo motor 4. Then, the slip ring 263 is moved downward by the hydraulic cylinder 265. When the U-shaped plate 262 is separated from the cylinder barrel, the cylinder barrel can be removed from the fixing mechanism 26.

[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
