Description

Technical Field

[0001] The utility model relates to the technical field of oil coolers, and in particular to an oil cooler seal detection device. Background Art

[0002] An oil cooler is an oil cooling device commonly used in hydraulic systems and lubrication systems. By using this device, two fluid media with a certain temperature difference can achieve heat exchange, so as to reduce the oil temperature and ensure the normal operation of the system. According to different heat exchange media, it can be divided into air-cooled oil coolers and water-cooled oil coolers, which are mainly used to cool hydraulic oil and lubricating oil; oil coolers are widely used in various industries such as plastic machinery, construction machinery, mining machinery, automobiles, steel, wind power, and aerospace.

[0003] In the production and processing process of oil coolers, in order to ensure the quality of the products, it is necessary to inspect the airtightness of the inner cavity of the cooler after the processing technology is completed, so as to avoid leakage problems during use and cause various losses to users. At present, the common pre-inspection of coolers is usually visual inspection after manual water injection, and the airtightness of the cooler cavity is determined by observing whether there is water leakage. However, this detection method has the problem of low detection efficiency. In addition, when the leakage point is fine, it is sometimes difficult to be observed, and it is easy to miss the inspection.

[0004] To sum up, there are technical problems of low detection efficiency and poor detection effect in the detection of the cavity airtightness of existing oil coolers. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is the technical problems of low detection efficiency and poor detection effect in the detection of the cavity airtightness of existing oil coolers.

[0006] To solve the above problems, the utility model provides an oil cooler seal detection device, which includes a detection placement table and a seal inflation assembly. The detection placement table is used to place and fix the oil cooler to be detected. The seal inflation assembly includes a piston seal rod that can be automatically controlled to feed. The outer diameter of the end of the piston seal rod matches the inner diameter of the inlet and outlet pipes of the oil cooler to be detected. An inflation port for inflating the inner cavity of the oil cooler to be detected is arranged at the end of the piston seal rod. After the piston seal rod feeds to close the inlet and outlet pipes of the oil cooler and inflates it, the air pressure in the inner cavity of the oil cooler is detected to detect the airtightness of the oil cooler.

[0007] The oil cooler sealing detection device provided by the utility model can effectively realize the automatic sealing detection of the inner cavity of the oil cooler. The detection device mainly includes a placement table and a sealing and inflating assembly arranged thereon. The oil cooler to be detected is positioned and placed on the placement table. The piston sealing rod of the sealing and inflating assembly is fed to block and seal the inlet and outlet pipes on the oil cooler. Since the outer diameter of the piston sealing rod matches the inner diameter of the inlet and outlet pipes, the inner and outer spaces of the oil cooler are completely isolated at this time. The oil cooler is inflated through the inflation port at the end of the piston sealing rod, and structures such as an auxiliary barometer are used to detect the air pressure in the inner cavity of the oil cooler. Whether the oil cooler has good air tightness can be judged through the air pressure value. This detection method has a high degree of automation, and the detection process does not need to be directly carried out by manpower, effectively solving the technical problems of low detection efficiency and poor detection effect in the existing cavity sealing detection of oil coolers.

[0008] As a preferred solution, the sealing and inflating assembly further includes a piston driving cylinder for outputting a linear feeding motion to drive the piston sealing rod to act, and the piston driving cylinder is connected to the detection placement table at an adjustable position. This design optimizes the feeding drive design of the piston sealing rod. The linear feeding drive is realized through a cylinder-like mechanism, and the operability is good.

[0009] As a preferred solution, the piston driving cylinder is installed and connected to the detection placement table through a displacement adjustment seat mechanism. The displacement adjustment seat mechanism includes a displacement slide rail fixedly connected to the detection placement table and a mounting seat slidably matched with the displacement slide rail. This design provides a design for fine adjustment of the position of the piston rod. The piston driving cylinder is slidably connected to the displacement slide rail located on the detection placement table, and the displacement adjustment space for the position of the piston driving cylinder is provided through the structure of the displacement slide rail to adapt to oil coolers with different sizes and different positions of inlet and outlet pipes, ensuring the universality of the detection equipment for different models.

[0010] As a preferred solution, one end of the mounting seat is provided with a slider slidably matched with the displacement slide rail, and the other end is provided with a hollow frame for connecting the piston driving cylinder. The piston driving cylinder is accommodated in the hollow frame, and a plurality of tension springs are connected between the outer edge of the piston driving cylinder and the hollow frame to elastically limit the position of the piston driving cylinder in the hollow frame.

[0011] This design optimizes the cooperation mode between the piston-driven cylinder and the sliding rail. The two are in variable-position sliding cooperation through a slider located at the bottom end of the mounting seat. At the other end, the mounting seat is box-shaped, with the cylinder located at the center of the box. A plurality of tension springs are connected between the inner edge of the box and the outer edge of the cylinder. Through such a structure, there is a certain elastic displacement margin between the cylinder and the mounting seat. With this structure, when there is a certain range of offset misalignment between the pipe orifice of the oil cooler and the piston rod, the normal feeding of the piston rod can be ensured through this elastic structure, ensuring that a good effect of sealing the pipe orifice can still be achieved in the case of misalignment.

[0012] As a preferred solution, the mounting seat is also connected with a displacement adjustment cylinder. The fixed end of the displacement adjustment cylinder is fixedly installed on the detection mounting table. Through the output feeding motion of the displacement adjustment cylinder, the piston-driven cylinder is controlled to slide on the displacement sliding rail to adjust the distance between the piston-driven cylinder and the pipe orifice to be detected for inlet and outlet. This design provides a structure for automatically adjusting the position of the cylinder and the piston rod driven by it. The linear feeding output by the displacement adjustment cylinder drives the mounting seat and the piston-driven cylinder thereon to slide and adjust the position on the displacement sliding rail. The auxiliary control unit can achieve the automatic adjustment of the cylinder position in this way.

[0013] As a preferred solution, the detection mounting table includes a table board and a pneumatic locking mechanism arranged on the table board. The pneumatic locking mechanism is respectively used to push and fix the outer shell of the oil cooler to be detected. The pneumatic locking mechanism includes a cylinder for outputting feeding and a pressure rod connected to the output end of the cylinder. By outputting feeding to drive the pressure rod to push and fix the position of the oil cooler placed on the table top, the automatic position correction or fixation of the oil cooler to be detected can be simply realized, facilitating the subsequent airtightness detection process.

[0014] As a preferred solution, the pneumatic locking mechanism includes a pair of locking and positioning cylinders respectively arranged on both sides of the oil cooler to be detected. This design optimizes the structure of the above pneumatic locking mechanism, provides two sets of pneumatic locking positions, and can further optimize the positioning effect of the oil cooler due to the addition of the top support fixing points.

[0015] As a preferred solution, a plurality of sets of the seal inflation assemblies are arranged on the detection mounting table, and the number of the seal inflation assemblies corresponds to the number of the inlet and outlet pipe orifices of the oil cooler to be detected. This design optimizes the adaptability of the device to the structure of the oil cooler, making the number and position of the seal inflation assemblies correspond to the inlet and outlet pipe orifices of the oil cooler.

[0026] In this embodiment, the provided oil cooler sealing detection device includes a detection placement table 1 and a sealing inflation assembly. The detection placement table 1 is used to place and fix the oil cooler 10 to be detected. The sealing inflation assembly includes a piston sealing rod 2 that can be automatically controlled for feeding. The outer diameter of the end of the piston sealing rod 2 matches the inner diameter of the inlet and outlet pipe orifice 11 of the oil cooler 10 to be detected. An inflation port 3 for inflating the cavity of the oil cooler 10 to be detected is provided at the end of the piston sealing rod 2. After the inlet and outlet pipe orifice 11 of the oil cooler 10 is closed by the feeding of the piston sealing rod 2 and inflated, the air pressure in the cavity of the oil cooler 10 is detected to detect the airtightness of the oil cooler 10.

[0027] The oil cooler sealing detection device provided by the present utility model can effectively realize the automatic sealing detection of the inner cavity of the oil cooler. The detection device mainly includes a placement table and a sealing inflation assembly arranged thereon. The oil cooler 10 to be detected is positioned and placed on the placement table. The inlet and outlet pipe orifice 11 on the oil cooler 10 is blocked and sealed by the feeding of the piston sealing rod 2 of the sealing inflation assembly. Since the outer diameter of the piston sealing rod 2 and the inner diameter of the inlet and outlet pipe orifice 11 cooperate with each other, the inner and outer spaces of the oil cooler 10 are completely isolated at this time. The oil cooler 10 is inflated through the inflation port 3 located at the end of the piston sealing rod 2, and structures such as an auxiliary barometer are used to detect the air pressure in the inner cavity of the oil cooler 10. Whether the oil cooler 10 has good airtightness can be judged through the air pressure value. This detection method has a high degree of automation, and the detection process does not need to be directly carried out by manpower, effectively solving the technical problems of low detection efficiency and poor detection effect in the existing detection of the cavity sealing of the oil cooler 10.

[0028] In the technical solution provided by this embodiment, the sealing inflation assembly further includes a piston driving cylinder 4 for outputting a linear feeding motion to drive the piston sealing rod 2 to act. The piston driving cylinder 4 is connected to the detection placement table 1 at an adjustable position. This design optimizes the feeding drive design of the piston sealing rod 2. The linear feeding drive is realized through a cylinder-like mechanism, and the ease of operation is good.

[0029] In the technical solution provided by this embodiment, the piston-driven cylinder 4 is installed and connected to the detection mounting table 1 through a displacement adjustment seat mechanism. The displacement adjustment seat mechanism includes a displacement slide rail 7 fixedly connected to the detection mounting table 1 and a mounting seat 5 slidably matched with the displacement slide rail 7. This design provides a design for fine adjustment of the position of the piston rod. The piston-driven cylinder 4 is slidably connected to the displacement slide rail 7 located on the detection mounting table 1, and the structure of the displacement slide rail 7 provides a displacement adjustment space for the position of the piston-driven cylinder 4 to adapt to oil coolers with different sizes and positions of the inlet and outlet pipes 11, ensuring the universality of the detection equipment for different models.

[0030] In the technical solution provided by this embodiment, one end of the mounting seat 5 is provided with a slider 8 slidably matched with the displacement slide rail 7, and the other end is provided with a hollow frame for connecting the piston-driven cylinder 4. The piston-driven cylinder 4 is accommodated in the hollow frame, and a plurality of tension springs 6 are connected between the outer edge of the piston-driven cylinder 4 and the hollow frame to elastically limit the position of the piston-driven cylinder 4 in the hollow frame.

[0031] This design optimizes the cooperation mode between the piston-driven cylinder 4 and the slide rail. The two are slidably and variably displaced through the slider 8 at the bottom of the mounting seat 5. At the other end, the mounting seat 5 is in a square shape, with the cylinder located at the center of the square. A plurality of tension springs 6 are connected between the inner edge of the square and the outer edge of the cylinder. Through such a structure, there is a certain elastic displacement margin between the cylinder and the mounting seat 5. Through this structure, when there is a certain range of offset misalignment between the pipe orifice of the oil cooler and the piston rod, the normal feeding of the piston rod can be ensured through this elastic structure, ensuring that a good effect of sealing the pipe orifice can still be achieved in the case of misalignment.

[0032] In the technical solution provided by this embodiment, the mounting seat 5 is also connected to a displacement adjustment cylinder 12. The fixed end of the displacement adjustment cylinder 12 is fixedly installed on the detection mounting table 1. The piston-driven cylinder 4 is controlled to slide on the displacement slide rail 7 through the output feeding motion of the displacement adjustment cylinder 12 to adjust the distance between the piston-driven cylinder 4 and the inlet and outlet pipe orifice 11 to be detected. This design provides a structure for automatically adjusting the position of the cylinder and the piston rod driven by it. The linear feeding output by the displacement adjustment cylinder 12 drives the mounting seat 5 and the piston-driven cylinder 4 thereon to slide and adjust the position on the displacement slide rail 7. The auxiliary control unit can achieve the automatic adjustment of the cylinder position in this way.

[0033] In the technical solution provided in this embodiment, the detection placement table 1 includes a table board and a pneumatic locking mechanism arranged on the table board. The pneumatic locking mechanism is respectively used to push and fix the outer shell of the oil cooler to be tested. The pneumatic locking mechanism includes a cylinder for outputting feed and a pressure rod connected to the output end of the cylinder. By outputting feed to drive the pressure rod to push and fix the position of the oil cooler placed on the table top, the automatic position correction or fixation of the oil cooler to be detected can be simply achieved, facilitating the subsequent airtightness detection process.

[0034] In the technical solution provided in this embodiment, the pneumatic locking mechanism includes a pair of locking and positioning cylinders 13 respectively arranged on both sides of the oil cooler to be tested. This design optimizes the structure of the above pneumatic locking mechanism and provides two sets of pneumatic locking positions. Due to the addition of the top support fixing points, the positioning effect of the oil cooler can be further optimized.

[0035] In the technical solution provided in this embodiment, multiple sets of seal inflation components are arranged on the detection placement table 1, and the number of seal inflation components corresponds to the number of inlet and outlet pipe orifices 11 of the oil cooler to be tested. This design optimizes the adaptability of the device to the structure of the oil cooler, making the number and position of the seal inflation components correspond to the inlet and outlet pipe orifices 11 of the oil cooler.
