Description

Technical Field

[0001] The invention relates to the field of rotary oil cylinder equipment, in particular to a composite integrated rotary oil cylinder with an internal leakage detection device. Background Art

[0002] The rotary cylinder is a tightly assembled accessory that uses hydraulics to gather very high torque in a very small space. Despite the high power, they can still be precisely and easily controlled. Rotary cylinders have been successfully used in almost all fields that require limited rotational motion and high torque. As the name suggests, rotary cylinders rely on hydraulic oil to achieve rotation. However, the existing rotary cylinders have more and more complex internal sealing structures. Once a leak occurs, it is not easy to find and can only be completely disassembled for troubleshooting, which greatly reduces the use effect of the rotary cylinder. Moreover, it is impossible to ensure the sealing effect of the internal sealing structure after disassembly and assembly, and there may also be internal leakage. That is, the existing rotary cylinders lack a detection device for internal leakage.

[0003] Therefore, the inventor of the present invention, in view of the above technical problems, aims to invent an integrated rotary cylinder with an internal leakage detection device. Summary of the invention

[0006] Preferably, the height of the detection channel is not higher than the lowest point of the driving cavity inside the moving block, that is, to ensure that when there is hydraulic oil leakage in the driving cavity, the hydraulic oil can flow into the detection channel in time and be detected in time through the detection pipeline and the oil outlet.

That is, the connection between the detection pipeline and the detection channel is realized, ensuring that when there is hydraulic oil leakage inside, the internal leakage can be detected in time through the detection pipeline and the detection channel and the leaked hydraulic oil can be discharged.

[0008] Preferably, the driving assembly includes a piston rod, a piston head is arranged on the piston rod, and the piston head is arranged in a driving cavity inside the moving block, the piston rod passes through both sides of the driving cavity of the moving block, and is connected to the left end cover and the right end cover at both ends of the sleeve, and the driving assembly also includes an oil inlet pipe, and the oil inlet pipe is provided in two groups, and the two groups of the oil inlet pipes can respectively pass the hydraulic oil into both sides of the piston head, and the hydraulic oil is always in the driving cavity.

[0009] Preferably, the piston head and the piston rod are integrally arranged, and the diameter of the piston rod is smaller than the diameter of the piston head, that is, the diameter of the piston rod can be increased, thereby improving the strength.

[0010] Preferably, a reciprocating rubber seal is formed between the piston head and the inner wall of the driving chamber, which ensures the smooth movement of the moving block, and can also divide the driving chamber into two by the piston head. By changing the size of the driving chambers on both sides of the piston head, the reciprocating movement of the moving block is realized, that is, the rack is driven to reciprocate, and the gear is driven to rotate by the rack, that is, the rotation of the rotary cylinder is realized.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] See attached Figure 1-3 As shown, an integrated rotary cylinder with an internal leakage detection device in this embodiment includes a sleeve 1, a moving block 2 is arranged in the sleeve 1, the moving block 2 is connected to a driving component 3, and under the action of the driving component 3, the moving block 2 can move along the inner wall of the sleeve 1, and a rack 4 is arranged on the moving block 2, and an opening 11 is arranged on the sleeve 1, and the rack 4 is always exposed at the opening 11, and a gear 5 is meshedly arranged on the rack 4, and the gear 5 is connected to a scraper 6, a left end cover 7 and a right end cover 8 are respectively arranged at both ends of the sleeve 1, and the left end cover 7 and the right end cover 8 are respectively used to fix the piston rod 31, and also include an internal leakage detection device 9, the internal leakage detection device 9 includes a detection pipeline 91 and a detection channel 92, the detection channel 92 is respectively arranged on the left end cover 7 and the right end cover 8, and the detection channel 92 is communicated with the inside of the sleeve 1, the two detection channels 92 are connected through the detection pipeline 91, and the detection pipeline 91 is also provided with an oil outlet 93.

[0025] The height of the detection channel 92 is not higher than the lowest point of the driving chamber 21 inside the moving block 2. That is, when there is hydraulic oil leakage in the driving chamber 21, the hydraulic oil can flow into the detection channel 92 in time and be detected in time through the detection pipeline 91 and the oil outlet 93.

[0026] The detection pipeline 91 includes a connector 911 and a connecting pipe 912. The connector 911 includes a two-way connector 911 and a three-way connector 911. The connector 911 is connected to two detection channels 92 respectively, and the two connectors 911 are further connected through a connecting pipe 912. One of the connection ports of the three-way connector 911 is an oil outlet 93. That is, the connection between the detection pipeline 91 and the detection channel 92 is realized, ensuring that when there is hydraulic oil leakage inside, the internal leakage can be detected in time through the detection pipeline 91 and the detection channel 92 and the leaked hydraulic oil can be discharged.

[0027] The driving assembly 3 includes a piston rod 31, on which a piston head 32 is arranged, and the piston head 32 is arranged in the driving chamber 21 inside the moving block 2. The piston rod 31 passes through both sides of the driving chamber 21 of the moving block 2 and is connected to the left end cover 7 and the right end cover 8 at both ends of the sleeve 1. The driving assembly 3 also includes an oil inlet pipe 33, and two groups of oil inlet pipes 33 are arranged. The two groups of oil inlet pipes 33 can respectively pass the hydraulic oil into both sides of the piston head 32, and the hydraulic oil is always in the driving chamber 21. It is ensured that the piston head 32 is in sealed contact with the inside of the driving chamber 21, and at the same time, the piston head 32 can drive the moving block 2 to move under the action of the hydraulic oil, ensuring the movement of the rack 4, that is, driving the rotation of the gear 5, and the scraper 6 also rotates.

[0028] The piston head 32 is integrally arranged with the piston rod 31, and the diameter of the piston rod 31 is smaller than the diameter of the piston head 32. That is, the diameter of the piston rod 31 can be increased, thereby improving the strength.

[0029] The piston head 32 and the inner wall of the driving chamber 21 are sealed by reciprocating rubber, which ensures the smooth movement of the moving block 2. The driving chamber 21 can also be divided into two by the piston head 32. By changing the size of the driving chamber 21 on both sides of the piston head 32, the reciprocating movement of the moving block 2 is realized, that is, the rack 4 is also driven to reciprocate, and the gear 5 is driven to rotate by the rack 4, that is, the rotation of the rotary cylinder is realized.

[0030] The oil inlet pipe 33 is arranged inside the piston rod 31 and along the axis of the piston rod 31, and leads to the outside of the piston rod 31 near the piston head 32. At the same time, two groups of oil inlet pipes 33 are symmetrically arranged on both sides of the piston head 32. That is, it is ensured that the amount of hydraulic oil passing through the two groups of oil inlet pipes 33 changes, driving the moving block 2 to move along the axis of the piston rod 31.

[0031] A sealing ring is provided at the position where the moving block 2 contacts the piston rod 31, which ensures that the hydraulic oil in the driving chamber 21 inside the moving block 2 will not leak, thus ensuring the timely driving.

[0032] See attached Figure 1 and 2 When the scraper 6 is working, it needs to swing, and the maximum swing angle is 72 degrees. In this device, the change of hydraulic oil in the driving chamber 21 is used to adjust the moving position of the moving block 2, and then adjust the movement of the rack 4 along the direction of the piston rod 31. The gear 5 is rotated by the meshing of the rack 4 and the gear 5. The gear 5 is connected with the scraper 6, and then the rotation of the scraper 6 is realized. During the working process, it is ensured that the hydraulic oil flows in the driving chamber 21 and cannot flow out. Therefore, an internal leakage detection device 9 is added. Through the cooperation of the detection pipeline 91 and the detection channel 92, when internal leakage occurs, it can be detected in time and the fault can be eliminated in a targeted manner, thereby improving the use efficiency of the rotary cylinder.

[0033] The beneficial effect of an integrated rotary cylinder with an internal leakage detection device is that the rotary cylinder has an additional leakage detection device, which can accurately determine the internal leakage condition after internal leakage occurs, without stopping the machine for detection, and directly replacing the corresponding parts, thereby solving the problem that when the original rotary cylinder has an internal leakage, it needs to be stopped and disassembled to find out the cause.

[0034] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
