Description

Technical Field

[0001] This utility model relates to the field of booster cylinder technology, specifically a booster cylinder. Background Technology

[0002] A booster cylinder is a fluid power actuator that converts the low-pressure energy of compressed air into the high-pressure energy of hydraulic oil, thereby achieving high power output with low power input. It combines the advantages of fast response and simple control of pneumatic transmission with the high pressure and high thrust of hydraulic transmission, and is widely used in industrial scenarios requiring high-pressure short-time operation, such as stamping, riveting, press fitting, and cutting.

[0003] Existing booster cylinders typically connect the cylinder barrel and oil reservoir via flanges, threads, or welding to achieve oil circuit connectivity and structural fixation. Traditional planar or threaded seals have limited contact area, making them prone to leakage under high-pressure oil due to loose sealing surfaces. Especially under vibration conditions, the seals are susceptible to fatigue wear, leading to reduced sealing performance and making them unsuitable for high-pressure working environments. Traditional connection methods also have stringent requirements for interface coaxiality, necessitating repeated calibrations during assembly, which is time-consuming and labor-intensive. Welded or integrated structures cannot be disassembled, and damage to partial components necessitates the complete scrapping of the equipment, increasing operating costs. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the above-mentioned problems and those existing in the booster cylinder, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A booster cylinder includes a cylinder barrel and an oil reservoir. The oil reservoir is disposed on the side of the cylinder barrel. A first connecting block is fixedly disposed in the middle of the cylinder barrel. A second connecting block is fixedly disposed at the bottom of the oil reservoir. A connecting component is disposed inside the second connecting block. A tapered opening is provided on the surface of the first connecting block near the second connecting block. The tapered opening is connected to an oil pipe inside the cylinder barrel.

[0007] As a preferred embodiment of the booster cylinder described in this utility model, the connecting assembly includes a tapered tube that mates with the tapered opening. A connecting cylinder is provided at the end of the tapered tube, and the connecting cylinder is movably connected to the oil pipe inside the oil storage tank.

[0008] In a preferred embodiment of the booster cylinder described in this utility model, a connecting rod is fixedly connected to the other end of the connecting cylinder, and a sealing block is installed at the other end of the connecting rod. A rotating shaft is provided on the surface of the sealing block away from the surface of the connecting rod, and the surface of the rotating shaft moves through the second connecting block.

[0009] In a preferred embodiment of the booster cylinder described in this utility model, a rotating arm is movably provided on the surface of the second connecting block, and the middle end of the rotating arm is fixedly connected to the rotating shaft.

[0010] In a preferred embodiment of the booster cylinder described in this utility model, the two ends of the rotating arm are provided with through holes, the first connecting block and the second connecting block are connected by bolts, and the surface of the bolts can move through the through holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The device adopts a conical sealing structure.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Example 1 Please see Figures 1-6 This utility model provides a technical solution: A booster cylinder includes a cylinder barrel 1 and an oil reservoir 2. The oil reservoir 2 is disposed on the side of the cylinder barrel 1. A first connecting block 3 is fixedly disposed in the middle of the cylinder barrel 1, and a second connecting block 4 is fixedly disposed at the bottom of the oil reservoir 2. A connecting component is disposed inside the second connecting block 4. A conical opening 5 is opened on the surface of the first connecting block 3 near the second connecting block 4. The conical opening 5 is connected to the oil pipe inside the cylinder barrel 1. The device adopts a conical sealing structure, which has a self-guiding function. During assembly, there is no need to repeatedly calibrate the interface position, and the oil circuit can be quickly connected, reducing the assembly difficulty. At the same time, the device is equipped with a capsule-type anti-loosening adhesive inside. Through the combined effect of chemical bonding and mechanical cooperation, it solves the problem of sealing failure caused by vibration and temperature changes in traditional mechanical seals.

[0020] The connecting assembly includes a tapered tube 6, which mates with a tapered opening 5. A connecting cylinder 7 is provided at the end of the tapered tube 6, and the connecting cylinder 7 is movably connected to the oil pipe inside the oil storage tank 2. The device adopts a tapered surface sealing structure. Compared with traditional flat or threaded seals, the tapered surface mating has a larger sealing contact area and can form a line seal or even a surface seal through axial pressure. Under the action of oil pressure, the sealing effect increases with the increase of pressure, effectively reducing the probability of leakage under high pressure conditions.

[0021] A connecting rod 8 is fixedly connected to the other end of the connecting cylinder 7. A sealing block 9 is installed at the other end of the connecting rod 8. A rotating shaft is provided on the surface of the sealing block 9 away from the surface of the connecting rod 8. The surface of the rotating shaft moves through the second connecting block 4. A rotating arm 10 is movably provided on the surface of the second connecting block 4. The rotating shaft is fixedly connected to the middle end of the rotating arm 10. Through holes are provided at both ends of the rotating arm 10. The first connecting block 3 and the second connecting block 4 are connected by bolts, and the surface of the bolts moves through the through holes. The two ends of the rotating arm 10 are limited by bolts to form a two-way constraint structure. When vibrating, the rotating arm 10 cannot swing freely, which indirectly locks the position of the tapered tube 6, avoids the problem of preload attenuation caused by vibration in traditional threaded connections, and significantly improves the vibration resistance of the connection structure.

[0022] In use, the operator first aligns the tapered tube 6 of the second connecting block 4 with the tapered opening 5 of the first connecting block 3. The tapered tube 6 and the tapered opening 5 form a preliminary positioning, ensuring precise alignment of the oil circuit interface. The operator then pushes the sealing block 9 to move the connecting rod 8 forward. Simultaneously, the connecting rod 8 pushes the connecting cylinder 7 and the tapered tube 6 closer to the tapered opening 5 until the tapered tube 6 is fully embedded in the tapered opening 5. At this point, the oil pipe inside the oil reservoir 2 forms a through-flow channel with the oil pipe inside the cylinder barrel 1 through the connecting cylinder 7 and the tapered tube 6, creating a channel for hydraulic oil transmission. The operator then rotates the rotating arm 10, which, through the rotating shaft, drives the sealing block 9 to further press the connecting rod 8. This allows the tapered tube 6 and the tapered opening 5 to fit tightly together, initially enhancing the connection seal. After the tapered tube 6 and the tapered opening 5 are fitted together, the bolts are passed through the through holes at both ends of the rotating arm 10, aligned with the threaded holes of the first connecting block 3 and the second connecting block 4, and tightened. When the bolts are tightened, on the one hand, the first connecting block 3 and the second connecting block 4 are rigidly fixed directly, realizing the structural connection between the cylinder barrel 1 and the oil reservoir 2. On the other hand, by squeezing the rotating arm 10, it is made to rotate slightly around the rotating shaft, further applying axial pressure to the sealing block 9, causing the tapered tube 6 and the tapered opening 5 to form an interference fit, thus strengthening the oil circuit sealing effect.

[0023] Example 2 Please see Figures 1-6 This utility model provides a technical solution: A pressure table 12 is provided on the end face inside the conical opening 5. The end of the conical tube 6 is in contact with the pressure table 12. When the conical tube 6 is engaged with the conical opening 5, the end of the conical tube 6 is tightly in contact with the pressure table 12 inside the conical opening 5. The conical surface engagement achieves initial sealing through radial pressure, while the contact between the pressure table 12 and the end face of the conical tube 6 further blocks the oil leakage path. During assembly, the rotating arm 10 applies axial pressure by tightening the bolts, so that the end of the conical tube 6 is firmly pressed on the pressure table 12. Elastic deformation occurs at the end face engagement point, filling the micro gaps and ensuring sealing reliability.

[0024] The surface of the tapered tube 6 is provided with a spiral groove 11, and the interior of the spiral groove 11 is filled with capsule-type anti-loosening adhesive. After the capsule-type anti-loosening adhesive breaks, it will have a chemical bonding effect. The structural design of the spiral groove 11 allows the anti-loosening adhesive to evenly cover the mating surface, avoiding anti-loosening failure caused by insufficient local adhesive. At the same time, the spiral path extends the possible leakage channel of oil, further improving the sealing effect.

[0025] Unlike Example 1, the spiral groove 11 on the surface of the conical tube 6 is filled with capsule-type anti-loosening adhesive. When the conical tube 6 and the conical opening 5 are assembled, the conical surfaces are squeezed and rubbed against each other, causing the capsule to rupture and release the adhesive. The cured anti-loosening adhesive bonds the conical tube 6 and the conical opening 5 together, forming a composite connection of mechanical fit and chemical bonding. It can not only fill the micro gaps such as the thread groove to enhance the sealing performance, but also prevent the two from being displaced relative to each other due to vibration through the adhesive force, thus achieving long-term anti-loosening.

[0026] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
