Description

Technical Field

[0001] This utility model relates to the field of steel pipe testing technology, and more specifically, it relates to a bracket for detecting leaks in hydraulic steel pipes of injection molding machines. Background Technology

[0002] In the hydraulic system of injection molding machines, the steel pipe connection points are high-risk areas for leakage. According to statistics, about 35% of injection molding equipment failures are related to hydraulic leakage. Traditional detection methods mainly rely on manual inspection, which has problems such as low detection efficiency and difficulty in identifying minor leaks.

[0003] In existing technologies, traditional supports use welded frames or integral cast structures, with fixed support spans. When testing short pipes, both ends are suspended, and for long pipes, additional supports are required, affecting the stability of the sensor readings. Circumferential testing of weld seams requires manual rotation of the pipe, causing inconvenience. Utility Model Content

A connecting hole 18 is provided on the partition plate 14 to cooperate with the plug 17. A support motor 19 is provided on the first movable seat 2. A support screw 20 is provided on the motor shaft of the support motor 19. The support screw 20 is threadedly connected to the support block 4. A drive screw 21 is threadedly connected on the second movable seat 3. A drive handle 22 is provided at one end of the drive screw 21. The moving device includes a moving groove 28. The moving grooves 28 are symmetrically arranged. A moving block 29 is slidably arranged in the moving grooves 28. The first movable seat 2 and the second movable seat 3 are arranged on the moving block 29. A moving motor 30 is provided on one side of the support platform 1. A moving screw 31 is provided on the motor shaft of the moving motor 30. The moving screw 31 is threadedly connected to the moving block 29. The threads of the moving screw 31 in the moving groove 28 are symmetrical and opposite.

[0030] In this embodiment, when inspecting the hydraulic steel pipe of the injection molding machine, the installation and use of the inspection machine adopt existing technology. This application only improves the support part of the steel pipe bracket. The moving motor 30 is started, and the moving motor 30 drives the moving screw 31 to rotate. The moving screw 31 drives the moving block 29 to move in opposite directions within the moving groove 28, thereby facilitating the movement of the first moving seat 2 and the second moving seat 3. If the steel pipe diameter is large, the steel pipe is sleeved on the outside of the support wheel 5 and the transmission wheel 11. If the steel pipe diameter is small, the steel pipe is placed between the support wheel 5 and the transmission wheel 11. Taking a large-diameter steel pipe as an example, the inside of the steel pipe is sleeved on the transmission wheel 11. Simultaneously, the support motor 19 is started on wheel 11. The support motor 19 drives the support screw 20 to rotate, which in turn drives the support block 4 to move and drives the support wheel 5 to support upward. At the same time, the drive handle 22 is rotated, which drives the drive screw 21 to rotate and drives the drive block 6 to move upward. At the other end, the steel pipe is supported by the drive wheel 9. Then, the drive motor 7 is started, which drives the drive wheel 9 to rotate. The drive wheel 9 can be provided with anti-slip texture to improve the friction between the inner wall of the steel pipe and the drive wheel 9, which in turn drives the steel pipe to rotate between the support wheel 5 and the transmission wheel 11. The rotation of the steel pipe improves the efficiency of leak detection.

[0031] Please see Figures 4-5As one embodiment of the drive shaft 10: a piston rod 23 is slidably provided on the drive shaft 10, a piston plate 24 is provided at one end of the piston rod 23, an oil injection hole 25 is provided on the drive shaft 10, a baffle 26 is slidably provided on the lubrication groove 12, and an oil injection spring 27 is provided between the baffle 26 and the lubrication groove 12.

[0032] More specifically, during use, the piston rod 23 is pulled outward, causing the piston plate 24 to move. When the piston plate 24 moves to the position of the baffle 26, it moves the baffle 26 and compresses the oil injection spring 27, opening the oil injection hole 25 and injecting lubricating oil into the lubrication groove 12. After oil injection is completed, the piston rod 23 is released, and the baffle 26, under the elastic force of the oil injection spring 27, moves the piston plate 24 back to its original position. At the same time, the baffle 26 blocks the oil injection hole 25. When lubricating between the drive shaft 10 and the drive wheel 11, press... The piston rod 23 is pressed, which drives the piston plate 24 to squeeze the lubricating oil. The lubricating oil squeezes the plug 17 and the control spring 16, causing the connecting hole 18 to open. The lubricating oil flows through the partition 14 and then through the connecting groove 13 to lubricate the transmission wheel 11 and the transmission shaft 10, reducing the friction between the transmission wheel 11 and the transmission shaft 10 when they rotate. At the same time, after the piston rod 23 and the piston plate 24 are released, the plug 17 is reset under the elastic force of the control spring 16, thereby blocking the connecting hole 18 and preventing further leakage of lubricating oil and waste.

[0033] In summary, during the use or operation of the overall equipment: when inspecting the hydraulic steel pipes of the injection molding machine, the installation and use of the inspection machine adopt existing technology. This application only improves the support part of the steel pipe bracket. The moving motor 30 is started, which drives the moving screw 31 to rotate. The moving screw 31 drives the moving block 29 to move in opposite directions within the moving groove 28, thereby facilitating the movement of the first moving seat 2 and the second moving seat 3. If the steel pipe diameter is large, the steel pipe is sleeved outside the support wheel 5 and the transmission wheel 11. If the steel pipe diameter is small, the steel pipe is placed between the support wheel 5 and the transmission wheel 11. Taking a large-diameter steel pipe as an example, the inner sleeve of the steel pipe... The support motor 19 is started simultaneously on the transmission wheel 11. The support motor 19 drives the support screw 20 to rotate, which in turn drives the support block 4 to move and the support wheel 5 to support upwards. At the same time, the drive handle 22 is rotated, which drives the drive screw 21 to rotate and drives the drive block 6 to move upwards. The steel pipe is supported at the other end by the drive wheel 9. Then the drive motor 7 is started, which drives the drive wheel 9 to rotate. The drive wheel 9 can be provided with anti-slip texture to improve the friction between the inner wall of the steel pipe and the drive wheel 9, which in turn drives the steel pipe to rotate between the support wheel 5 and the transmission wheel 11. The rotation of the steel pipe improves the efficiency of leak detection.

[0034] In use, pull the piston rod 23 outward, causing the piston rod 23 to move the piston plate 24. When the piston plate 24 moves to the position of the baffle 26, it moves the baffle 26 and compresses the oil injection spring 27, opening the oil injection hole 25 and injecting lubricating oil into the lubrication groove 12. After oil injection is completed, release the piston rod 23. Under the elastic force of the oil injection spring 27, the baffle 26 moves the piston plate 24 back to its original position and simultaneously blocks the oil injection hole 25 through the baffle 26. When lubricating between the drive shaft 10 and the drive wheel 11, press the piston rod 23. The piston rod 23 drives the piston plate 24 to squeeze the lubricating oil. The lubricating oil squeezes the plug 17 and the control spring 16, causing the connecting hole 18 to open. The lubricating oil flows through the partition 14 and then through the connecting groove 13 to lubricate the transmission wheel 11 and the transmission shaft 10, reducing the friction between the transmission wheel 11 and the transmission shaft 10 when the transmission wheel 11 rotates. At the same time, after the piston rod 23 and the piston plate 24 are released, the plug 17 is reset under the elastic force of the control spring 16, thereby blocking the connecting hole 18 and preventing further leakage of lubricating oil and waste.
