Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder inner diameter detection technology, and specifically to a hydraulic cylinder pipe inner diameter detection device. Background Technology

[0002] Hydraulic cylinder tube inner diameter testing is a crucial step in ensuring the performance and safety of hydraulic systems. The accuracy of the hydraulic cylinder tube inner diameter test directly affects the stability and lifespan of the equipment. During testing, the inner wall of the hydraulic cylinder tube must be cleaned, and oil stains and rust should be avoided to prevent them from affecting the measurement.

[0003] Common mechanical probes or rigid probes come into direct contact with the inner wall of the oil pipe cylinder during the testing process, which can scratch the chrome plating or the high-gloss inner wall, increasing the risk of seal failure in subsequent use.

[0004] Therefore, a hydraulic cylinder pipe inner diameter detection device is proposed to solve the problem that contact probes and rigid probes will scratch the inner wall of the cylinder. Utility Model Content

[0005] The technical problem to be solved by this utility model is that contact probes and rigid probes can cause scratches on the inner wall of the hydraulic cylinder. Therefore, a hydraulic cylinder pipe inner diameter detection device is proposed.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a hydraulic cylinder pipe inner diameter detection device, including a fixed plate, a transparent frame and a hydraulic cylinder body. A first electric push rod is fixedly connected to the upper end of the fixed plate, and a support platform is fixedly connected to the upper end of the first electric push rod. A V-groove is opened on the upper end of the support platform. A second electric push rod is fixedly connected inside the transparent frame. A pressure block is fixedly connected to the output end of the second electric push rod. A first groove is opened on the upper end of the fixed plate. A bidirectional screw is rotatably connected to one side of the fixed plate located in the first groove. Slider blocks are threadedly connected to both sides of the bidirectional screw that are far apart from each other. A support plate is fixedly connected to the upper end of the slider. A first motor is fixedly connected to one side of one of the support plates. A rotating block is fixedly connected to the output end of the first motor. A second motor is fixedly connected inside one of the rotating blocks. A first screw is fixedly connected to the output end of the second motor. A moving block is threadedly connected to the first screw. A distance sensor is fixedly connected to the upper side of the moving block. A display screen is connected to one side of the distance sensor through a wire. The display screen is fixedly connected to one side of the transparent frame.

[0007] As a preferred technical solution of this utility model, another rotating block has a positioning hole on one side, and a rod is inserted into the positioning hole and fixedly connected to the first screw. By setting the positioning hole and the rod, the hydraulic cylinder body can be disassembled and installed under the adjustment of the bidirectional screw.

[0008] As a preferred technical solution of this utility model, a movable ring is sleeved on the rotating block, and a conical guide cover is fixedly connected to one side of the movable ring. The conical guide cover corresponds to both ends of the hydraulic cylinder body. By setting the conical guide cover, the hydraulic cylinder body can be temporarily limited by manual movement, thereby locating the center point of the hydraulic cylinder body.

[0009] As a preferred technical solution of this utility model, a connecting ring is fixedly connected to one side of each of the two rotating blocks. A rotating ring is internally threaded to the connecting ring. A folding cover is fixedly connected to one side of the rotating ring. One side of the folding cover is fixedly connected to the moving block. By setting the folding cover, dust and debris are reduced from adhering to the first screw, thus reducing the movement of the moving block.

[0010] As a preferred technical solution of this utility model, an alarm is connected to the bottom side of the display screen via a wire. The alarm is fixedly connected to one side of the transparent frame. By setting the alarm, an alarm can be triggered when the monitoring distance changes.

[0011] This utility model has the following advantages: by installing a bidirectional screw on the fixed plate, it can drive the two relative sliders and the support plate to move, and make the first screw disengage from the rotating block, so that the hydraulic cylinder body can be placed between the support platform and the pressure block. Then, the first motor and the second motor drive the rotating block and the first screw to rotate, so that the moving block and the distance sensor can provide rotation monitoring of the inner wall of the hydraulic cylinder body, which can improve the detection effect and accuracy. Moreover, through the non-contact structure, scratches on the inner wall of the hydraulic cylinder can be avoided. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The hydraulic cylinder pipe inner diameter detection device shown includes a fixed plate 1, a transparent frame 2, and a hydraulic cylinder body 5. A first electric push rod 3 is fixedly connected to the upper end of the fixed plate 1, and a support platform 4 is fixedly connected to the upper end of the first electric push rod 3. When the hydraulic cylinder body 5 is placed in a V-groove, the first electric push rod 3 can drive the support platform 4 and the hydraulic cylinder body 5 to move upward. A V-groove is opened at the upper end of the support platform 4. A second electric push rod 6 is fixedly connected inside the transparent frame 2. When the second electric push rod 6 extends, it can drive a pressure block 7 to cooperate with the support platform 4 to limit the hydraulic cylinder body 5. The output end of the second electric push rod 6 is fixedly connected to the pressure block 7. A first groove is opened at the upper end of the fixed plate 1. A bidirectional screw 8 is rotatably connected to one side of the fixed plate 1 located in the first groove. Rotating the bidirectional screw 8 can drive the slider 9 to move relative to each other, so that one end of the first screw 12 is connected to the slider 9. Another rotating block 11 is connected, and sliders 9 are threadedly connected to both sides of the bidirectional screw 8. A support plate 10 is fixedly connected to the upper end of the slider 9. A first motor is fixedly connected to one side of one of the support plates 10. The output end of the first motor is fixedly connected to the rotating block 11. Both the first motor and the second motor are drive motors, and their models can be purchased on the market. A second motor is fixedly connected inside one of the rotating blocks 11. A first screw 12 is fixedly connected to the output end of the second motor. A moving block 13 is threadedly connected to the first screw 12. A distance sensor 14 is fixedly connected to the upper side of the moving block 13. The distance sensor 14 is a laser rangefinder. A display screen 15 is connected to one side of the distance sensor 14 through a wire. The display screen 15 is fixedly connected to one side of the transparent frame 2 and displays the distance signal through the display screen 15.

[0018] One of the rotating blocks 11 has a positioning hole on one side, and a rod is inserted into the positioning hole and fixedly connected to the first screw 12. The positioning hole and the rod can connect the first screw 12 to the other rotating block 11.

[0019] Among them, a movable ring 16 is sleeved on the rotating block 11, and a conical guide cover 17 is fixedly connected to one side of the movable ring 16. The conical guide cover 17 corresponds to both ends of the hydraulic cylinder body 5. By setting the conical guide cover 17, the center point of the hydraulic cylinder body 5 can be made to coincide with the center point of the rotating block 11 by manual movement.

[0020] Among them, each of the two rotating blocks 11 is fixedly connected to a connecting ring 18 on one side of the opposite side. The connecting ring 18 is internally threaded to a rotating ring 19. A folding cover 20 is fixedly connected to one side of the rotating ring 19. One side of the folding cover 20 is fixedly connected to the moving block 13. By setting the folding cover 20 to connect the rotating block 11 and the rotating ring 19 respectively, it is easy to shield the first screw 12, reduce dust contact, and reduce the impact of the moving block 13's movement sluggishness on monitoring accuracy.

[0021] An alarm is connected to the bottom of the display screen 15 via a wire. The alarm is fixedly connected to one side of the transparent frame 2. When the display screen 15 detects an incorrect distance signal, it can convert the signal into an electrical signal and trigger the alarm to sound, thus alerting the personnel.

[0022] Working principle: Rotating the bidirectional screw 8 causes the two sliders 9 to move away from each other. At this time, the first screw 12 disengages from the other rotating block 11. Then, the hydraulic cylinder body 5 is placed on the support platform 4. The moving ring 16 and the conical guide cover 17 are then manually adjusted to connect the two sides of the hydraulic cylinder body 5, and to make the center point of the hydraulic cylinder body 5 and the rotating block 11 align with the same central axis. After adjusting to the appropriate position, the support platform 4 and the pressure block 7 are used to stabilize and limit the hydraulic cylinder body 5. Furthermore, after disassembling the conical guide cover 17, the first motor and the second motor can be started to control the rotation of the rotating block 11 and the first screw 12. Then, the moving block 13 moves and rotates inside the hydraulic cylinder body 5 and performs distance detection on the inner wall of the hydraulic cylinder body 5. The detection data can be displayed intuitively on the display screen 15.

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.
