Description

Technical Field

[0001] The utility model belongs to the technical field of sealing component detection, and more specifically, relates to a hydraulic sealing component detection device. Background Art

[0002] Hydraulic seals refer to accessories with sealing function, which have extremely small leakage and good sealing effect.

[0003] The core reason for testing the sealing of hydraulic parts is to prevent hydraulic oil leakage and ensure the normal operation and safety of the hydraulic system. In the hydraulic system, the hydraulic oil in the high-pressure chamber may leak into the low-pressure chamber through poorly sealed parts, resulting in insufficient system pressure and affecting work efficiency. At the same time, hydraulic parts with good sealing can maintain a high volumetric efficiency to ensure the stability of the working pressure and flow of the hydraulic system. Therefore, most hydraulic parts need to be tested for sealing after production. During the testing process, the workpiece is usually placed on the workbench and fixed with fixings. Then gas is injected into the workpiece, and the internal air pressure stability is detected by the sensing device to determine whether there is a leak. However, this detection method is not stable enough. After long-term use, the internal sensing device of the machine may be worn out, or the power system may be unstable, which will affect the results of the data detection, and thus make the device have certain limitations.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a hydraulic seal detection device is provided to achieve a more practical purpose. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0023] As attached Figure 1 To the attached Figure 5 As shown:

[0024] The utility model provides a hydraulic seal detection device, which includes a main body 1, a PLC controller 2 is installed on one side of the main body 1, a slot 3 is opened on one side of the main body 1, a cylinder 4 is installed above the inner wall of the slot 3, two connecting columns 5 are also installed above the inner wall of the slot 3, the two connecting columns 5 are respectively located on both sides of the cylinder 4, a connecting plate 6 is commonly installed below the two connecting columns 5, connecting rods 7 are installed at the four corners below the connecting plate 6, a bottom plate 8 is commonly installed below the multiple connecting rods 7, a fixed platform 10 is installed at the center of the upper surface of the bottom plate 8, a workpiece body 11 is arranged above the fixed platform 10, a groove 13 is arranged below the inner wall of the slot 3, and a linkage mechanism is arranged inside the groove 13.

[0025] Among them, the linkage mechanism includes a water storage frame 14, and fixed blocks 15 are installed on both sides of the water storage frame 14. The water storage frame 14 and the two fixed blocks 15 are slidably connected to the inner wall of the groove 13. The inner walls of the two fixed blocks 15 are respectively threaded with a first threaded rod 16 and a second threaded rod 17. The tops of the first threaded rod 16 and the second threaded rod 17 pass through the corresponding fixed block 15 and extend above it. The bottom of the first threaded rod 16 passes through the corresponding fixed block 15 and is rotatably connected to the inner bottom of the groove 13. The bottom of the second threaded rod 17 passes through the corresponding fixed block 15 and is installed with a motor 20. The motor 20 is installed at the inner bottom of the groove 13. Pulleys 18 are installed on the bottom sides of the first threaded rod 16 and the second threaded rod 17. A transmission belt 19 is connected between the two pulleys 18. The motor 20 and the pulley 18, the first threaded rod 16, the second threaded rod 17, the water storage frame 14, and the fixed block 15 are used in conjunction with each other. When the sensing device inside the device fails or the power system is unstable, the workpiece is fixed in advance. Then, gas is supplied through the external connecting pipe of the air guide port 27 to fill the inside of the workpiece with gas. After that, the motor 20 starts and drives the two linkage mechanisms to operate, so that the water storage frame 14 rises until the water completely covers the workpiece body 11 and then stops. At this time, it can be observed with the naked eye whether there are bubbles in the water layer around the workpiece body 11. If so, it means that the sealing is poor. Otherwise, it means that the sealing is intact. This device provides another manual observation detection method, so that when the sensing device fails, the detection work can still be carried out, thereby improving the practicality of the device.

[0026] Among them, vertical plates 21 are installed on both sides of the upper surface of the bottom plate 8, and electric cylinders 22 are installed on one side of the two vertical plates 21. One end of the two electric cylinders 22 is installed with a clamping plate 23, and a plurality of mounting grooves are provided on the corresponding side of the two clamping plates 23. Springs 24 are installed on one side of the inner walls of the plurality of mounting grooves, and abutment columns 25 are installed on one end of the plurality of springs 24. The sizes of the plurality of abutment columns 25 are adapted to the corresponding mounting grooves. The two clamping plates 23 are symmetrically arranged on the left and right sides of the workpiece body 11 respectively. The corresponding clamping plates 23 are driven to operate by the electric cylinder 22, and the plurality of abutment columns 25 are driven to clamp the workpiece body 11, thereby improving the stability of the workpiece body 11. At the same time, under the action of multiple springs 24, the abutment columns 25 can be expanded and contracted along with the shape of the workpiece body 11, so that the abutment columns 25 can better adapt to the shape of the workpiece body 11 and are more convenient for clamping.

[0027] Among them, an opening 9 is opened on the upper surface of the connecting plate 6, and the bottom end of the cylinder 4 passes through the opening 9 and is installed with a detection head 12. The detection head 12 is adapted to and abuts the top of the workpiece body 11. Through the setting of the detection head 12, the top of the workpiece body 11 is abutted and stabilized.

[0028] Among them, an air pressure sensor 26 is installed above the inner wall of the detection head 12. The air pressure sensor 26 is electrically connected to the PLC controller 2 through a wire. Through the setting of the air pressure sensor 26, the air pressure value inside the workpiece body 11 can be detected, and the data can be sent to the PLC controller 2 through the wire. The staff can judge whether the sealing of the workpiece body 11 is intact through the data display.

[0029] Among them, an air guide port 27 is opened on one side of the upper surface of the detection head 12. The staff connects a connecting pipe to the air guide port 27 and inputs gas into the workpiece body 11 through the connecting pipe, thereby facilitating the sealing detection work.

[0030] The two clamping plates 23 , the plurality of abutting columns 25 , the connecting rod 7 , the bottom plate 8 , the vertical plate 21 , and the fixing platform 10 are all made of metal materials, which have good waterproof properties.

[0031] The working principle of this embodiment is as follows: first, the workpiece body 11 is placed on the fixed table 10, and the electric cylinder 22 on one side of the two vertical plates 21 is started. The electric cylinder 22 pushes the clamping plate 23 to move toward the workpiece body 11. Under the action of the spring 24, the multiple abutment columns 25 on the clamping plate 23 are expanded and contracted according to the shape of the workpiece body 11, and the workpiece body 11 is stably clamped. Then, the cylinder 4 above the inner wall of the slot 3 pushes the detection head 12 under the connecting plate 6 to move downward, and the detection head 12 abuts against the top of the workpiece body 11 to stabilize it. The staff inputs gas into the workpiece body 11 through the air guide port 27 on one side of the upper surface of the detection head 12. The air pressure sensor 26 above the inner wall of the detection head 12 detects the air pressure value inside the workpiece body 11 and sends the data to the PLC controller 2 through the wire. The staff judges whether the sealing of the workpiece body 11 is intact based on the data display.

[0032] When the sensing device (air pressure sensor 26) inside the device fails or the power system is unstable, the workpiece body 11 is first clamped and fixed with the clamping plate 23, and gas is supplied through the external connecting pipe of the air guide port 27 to fill the workpiece body 11 with gas, and the motor 20 is started. The motor 20 drives the second threaded rod 17 to rotate, and the pulley 18 at the bottom of the second threaded rod 17 drives the pulley 18 at the bottom of the first threaded rod 16 to rotate through the transmission belt 19, so that the first threaded rod 16 and the second threaded rod 17 rotate synchronously, and the rotation of the first threaded rod 16 and the second threaded rod 17 drives the two fixed blocks 15 threadedly connected to them to rise, and the fixed blocks 15 drive the water storage frame 14 to rise. The water storage frame 14 rises until the water completely covers the workpiece body 11 and then stops. At this time, the staff observes the water layer around the workpiece body 11 with the naked eye to see whether there are bubbles. If so, it means that the sealing is poor. Otherwise, it means that the sealing is intact.
