Description

Technical Field

[0001] The invention relates to the technical field of hydraulic cylinder sealing detection, and in particular to a hydraulic cylinder sealing detection device for a shearing machine. Background Art

[0002] The hydraulic cylinder of the shearing machine is an important part of the hydraulic system. It uses the pressure of the hydraulic oil to drive the piston to move, thereby realizing the shearing action of the shearing machine. During the production process of the hydraulic cylinder of the shearing machine, a sealing detection device is needed to detect the sealing of the hydraulic cylinder of the shearing machine to ensure the normal operation of the hydraulic cylinder of the shearing machine. In the prior art, the sealing detection device detects the hydraulic cylinder of the shearing machine. Usually, the hydraulic cylinder of the shearing machine is immersed in water to observe whether there is a leak. However, when the hydraulic cylinder of the shearing machine is just immersed in water, the dust attached to the hydraulic cylinder of the shearing machine and the residual oil will float on the water surface, affecting the observation of the leakage of the hydraulic cylinder of the shearing machine. At the same time, the floating oil cannot determine whether it is the leaked hydraulic oil, resulting in a large error in the sealing detection of the hydraulic cylinder of the shearing machine. For this reason, the present invention improves the sealing detection device that can improve the accuracy of the sealing detection of the hydraulic cylinder of the shearing machine. Summary of the invention

[0003] The disclosed embodiment relates to a sealing detection device for a hydraulic cylinder of a shearing machine. The hydraulic cylinder of the shearing machine is immersed in the water inside a detection water tank for detection. The drainage groove outside the water inlet duct absorbs the water surface position inside the detection water tank, so that the water containing dust and oil flows into the filter module, and the water surface is cleaned, thereby reducing the dust and oil carried on the hydraulic cylinder of the shearing machine floating on the water surface to affect the airtightness detection of the hydraulic cylinder of the shearing machine, reducing residual oil, and ensuring that only the oil leaked from the hydraulic cylinder of the shearing machine floats on the water surface during the detection process, thereby ensuring the accuracy of the sealing detection of the hydraulic cylinder of the shearing machine.

[0010] In at least some embodiments, a lower guide pipe is installed at the bottom of the filter module; a reverse flow valve is installed on the lower guide pipe, and the bottom of the lower guide pipe passes through the left bottom of the detection water tank and is connected to the water outlet conduit; the water outlet conduit is installed at the inner bottom of the detection water tank, and multiple water outlet troughs are installed on the side of the water outlet conduit.

[0011] In at least some embodiments, two ends of a movable slide are slidably mounted inside the two guide grooves; a guide transverse groove is provided on the front side of the movable slide; and a movable plate is slidably mounted inside the guide transverse groove.

When the hydraulic cylinder of the shearing machine is tested for sealing, the collecting cover is located above the water inside the test water tank. The conical structure collecting cover can divert the oil that may leak, and the oil is collected at the inner top of the collecting cover, which is more intuitive to observe. When the hydraulic cylinder of the shearing machine leaks, and the leakage position is small, resulting in a small amount of hydraulic oil flowing out, the collecting cover plays a certain collecting role, thereby improving the accuracy of the detection of the hydraulic cylinder of the shearing machine and preventing omissions.

Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 9 :

[0035] Embodiment 1:

[0036] The present invention proposes a sealing detection device for a hydraulic cylinder of a plate shearing machine, comprising: a detection water tank 1, which is a rectangular structure, and the front and rear sides of the detection water tank 1 are inlaid with glass, and a driving cylinder is installed on the right side of the detection water tank 1, and a fixed bracket 101 is installed at the edge position of the outer side of the detection water tank 1; a supporting carrier plate 102 is installed on the inner bottom of the detection water tank 1; a positioning plate 103 is installed on the top of the fixed bracket 101; the positioning plate 103 is a rectangular plate structure, a push cylinder is installed in the middle position of the positioning plate 103, a pressure sensor is installed on the output end of the bottom of the push cylinder, and the bottom of the pressure sensor is connected to the top of the force plate 104; a positioning fixing frame 105 is installed on the output end of the driving cylinder on the right side of the detection water tank 1; the positioning fixing frame 105 is a rectangular frame structure, and the bottom of the positioning fixing frame 105 is installed Two guide vertical rods 106; the guide vertical rods 106 are cylindrical structures, and the bottoms of the two guide vertical rods 106 are connected to the tops of the two ends of the fixed support plate 107; a drain hole is provided at the bottom of the fixed support plate 107, a shearing machine hydraulic cylinder is installed on the inner side of the top of the fixed support plate 107, and the bottom of the fixed support plate 107 is moved downward and installed on the supporting carrier plate 102; a guide vertical groove 108 is provided on the side of one guide vertical rod 106, and a rotating drive rod 109 is rotatably installed inside the guide vertical groove 108; the top of the rotating drive rod 109 passes through the top of the positioning fixing frame 105 and a driving handle is installed; the two sides of the collecting cover 1010 are slidably installed on the outer sides of the two guide vertical rods 106; the collecting cover 1010 is a conical structure, and one side of the collecting cover 1010 is installed on the rotating drive rod 109 inside the guide vertical groove 108.

[0037] The bottom of the fixed support plate 107 is placed on the supporting plate 102 to ensure the stability of the hydraulic cylinder of the shearing machine during the inspection. The height of the collecting cover 1010 is adjusted according to the amount of water in the inspection water tank 1. The rotating driving rod 109 is rotated in the guide vertical groove 108 outside the guide vertical rod 106. The rotating driving rod 109 drives the collecting cover 1010 to move up and down along the two guide vertical rods 106. 1010 is in a suitable position. When the hydraulic cylinder of the shearing machine on the fixed support plate 107 is running, the glass on the front and rear sides of the water tank 1 can be used to observe whether there is any leakage. The pushing cylinder on the positioning plate 103 on the top of the fixed bracket 101 can also drive the force plate 104 to move downward, so that the force plate 104 applies pressure to the hydraulic cylinder of the shearing machine to simulate the pressure generated by the hydraulic cylinder of the shearing machine shearing material, and detect whether there is any leakage and poor sealing. The pressure sensor between the force plate 104 and the pushing cylinder can apply different pressures for detection, and the detection result is relatively comprehensive. The collecting cover 1010 is located on the upper part of the water inside the detection water tank 1, so that the collecting cover 1010 collects the oil leaking from the hydraulic cylinder of the shearing machine, which is more intuitive to observe, especially when the leakage part of the hydraulic cylinder of the shearing machine is small, so that less oil can be collected for observation to prevent omissions.

[0038] Embodiment 2, on the basis of embodiment 1, a filter module 2 is installed on the left side of the detection water tank 1; a circulation pump is installed on the top of the filter module 2, and an upper guide pipe 201 is installed on the output end of the top of the circulation pump; the top of the upper guide pipe 201 passes through the left top of the detection water tank 1 and is connected with the water inlet conduit 202; the water inlet conduit 202 is installed at the inner top of the detection water tank 1, and a drainage groove 203 is opened on the side of the water inlet conduit 202; a lower guide pipe 204 is installed at the bottom of the filter module 2; a reverse flow valve is installed on the lower guide pipe 204, and the bottom of the lower guide pipe 204 passes through the left bottom of the detection water tank 1 and is connected with the water outlet conduit 205; the water outlet conduit 205 is installed on the inner bottom of the detection water tank 1, and multiple water outlet grooves 206 are installed on the side of the water outlet conduit 205. When the hydraulic cylinder of the shearing machine is tested for sealing, when the fixed support plate 107 drives the hydraulic cylinder of the shearing machine to immerse in the water inside the detection water tank 1, the detection water tank 1, the circulating pump on the filter module 2 on the left side of the water inlet conduit 202 is working, and the water inlet conduit 202 is at the water surface position of the water inside the detection water tank 1, so that the drainage groove 203 on the side of the water inlet conduit 202 absorbs the dust and oil on the water surface caused by the immersion of the hydraulic cylinder of the shearing machine, so that the water carrying dust and oil enters the filter module 2 through the water inlet conduit 202 and the upper guide pipe 201 for purification and filtration, and then flows out through the lower guide pipe 204. The reverse flow valve on the lower guide pipe 204 reduces the backflow of water, so that the filtered water flows through the lower guide pipe 204 to flow into the water outlet conduit 205, and then flows out through the water outlet groove 206 on the side of the water outlet conduit 205, replenishing the water inside the detection water tank 1, preventing the situation that the water flow is reduced and cannot immerse the hydraulic cylinder of the shearing machine, ensuring the cleanliness of the water flow, preventing the presence of more impurities during the detection from affecting the detection of the leakage position of the hydraulic cylinder of the shearing machine, and ensuring the accuracy of the sealing detection of the hydraulic cylinder of the shearing machine.

When the sealing of the hydraulic cylinder of the shearing machine is tested, the movable slide plate 302 is slid along the two guide grooves 3, and the movable plate 304 slides along the guide transverse groove 303, so that the movable plate 304 is in a suitable position, and the pulling force on the connecting plate 307 is lost at the front bottom of the movable slide plate 302. Under the action of the spring, the inner sides of the two ends of the connecting plate 307 drive the fixed plug rod 308 to be inserted into the fixed socket 301, and the position of the movable slide plate 302 is fixed. The leakage position of the hydraulic cylinder of the shearing machine is observed through the convex lens on the inner side of the movable plate 304. At the same time, the dial plate 306 is rotated in the slot on the side of the rotating member 305.
