Description

Technical Field

[0001] This utility model relates to the field of hydraulic coupling technology, specifically to a hydraulic coupling connection device. Background Technology

[0002] As a core component in mechanical transmission systems that enables flexible starting and overload protection, the reliability of the hydraulic coupling directly affects the overall operating efficiency of the machine. In industrial settings such as metallurgy, mining, and power, where frequent adjustments to equipment parameters are required, the ability to quickly assemble and disassemble motor shafts of different specifications has become a key requirement for improving maintenance efficiency.

[0003] However, existing hydraulic coupling connection devices generally suffer from insufficient adaptability. Most adopt a fixed shaft hole structure, which can only match a single-size motor shaft. When equipment is upgraded or the shaft is replaced, the entire connection assembly often needs to be replaced, leading to a significant increase in spare parts costs. Traditional clamping methods mostly rely on bolt tightening or key connections, requiring repeated adjustments of multiple sets of fasteners during operation. This is not only time-consuming to install and disassemble, but also prone to shaft bending and deformation due to uneven stress. More seriously, rigid metal contact can easily form indentations on the shaft surface, accelerating journal wear, while the transmission structure, lacking self-locking function, is prone to loosening under vibration conditions, easily causing equipment downtime accidents. Although some improved solutions introduce hydraulic assisted clamping, they require a dedicated pump station, limiting their application in space-constrained downhole or high-temperature environments. These technical bottlenecks severely restrict the widespread application of hydraulic couplings in multi-model adaptation scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic coupling connection device that, through the coordinated design of a worm gear and six sets of adjusting plates, enables quick assembly / disassembly and reliable fixation of the motor shaft. Rotating the handle drives the worm gear, which, via inclined plane transmission, causes the adjusting plates to move radially synchronously. The six sets of adjusting plates are precisely aligned along the guide grooves, and the elastic deformation of the rubber pads achieves non-destructive clamping.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic coupling connection device for assembling motor shafts, comprising a hydraulic coupling, wherein the hydraulic coupling is provided with a connection mechanism for assembling and connecting motor shafts of different sizes and specifications.

[0006] The connecting mechanism includes a mounting plate disposed on the hydraulic coupling, a support frame disposed outside the mounting plate, a connecting top plate fixed to one end of the support frame away from the mounting plate, a movable plate rotatably disposed at the bottom end of the connecting top plate, and at least six adjusting plates for fixing the motor shaft slidably disposed below the movable plate.

[0007] Preferably, the mounting plate has a guide groove, and a movable block is slidably disposed in the guide groove. The top end of the movable block is fixedly connected to the bottom end of the adjusting plate.

[0008] Preferably, at least six sets of movable blocks are provided, and the six sets of movable blocks are circumferentially distributed in the guide groove with the center of the mounting plate as the center.

[0009] Preferably, each of the adjusting plates has a connecting post fixed to its top, and the movable plate has a strip groove. Each connecting post contacts the inner wall of a strip groove.

[0010] Preferably, a rubber pad is fixed to the outer wall of each adjustment plate near the center.

[0011] Preferably, a worm gear is fixed to the outer wall of the movable disk, and a mounting frame is fixed to the outer wall of the mounting disk. A worm is rotatably mounted inside the mounting frame, and the worm meshes with the worm gear.

[0012] Preferably, a handle is fixed to one end of the worm gear.

[0013] Compared with the prior art, the present invention provides a hydraulic coupling connection device, which has the following advantages: This hydraulic coupling device, through the coordinated design of a worm gear and six sets of adjusting plates, enables quick assembly / disassembly and reliable fixation of the motor shaft. During operation, rotating the handle drives the worm gear, which in turn rotates the worm wheel, causing the movable disc to rotate. Utilizing the engagement of the slotted groove and the inclined surface of the connecting column, the rotational motion is converted into the radial synchronous convergence or expansion of the adjusting plates. The six adjusting plates are precisely aligned along the guide grooves, and the rubber pads achieve non-destructive clamping through elastic deformation. Assembly and disassembly can be completed simply by rotating the handle, requiring no additional tools. The self-locking characteristic of the worm gear effectively prevents loosening caused by vibration, ensuring operational stability. Attached Figure Description

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a hydraulic coupling connection device for assembling a motor shaft 1, including a hydraulic coupling 2, on which a connection mechanism 3 is provided for assembling and connecting motor shafts 1 of different sizes and specifications. By setting an adjustable connection mechanism 3, universal assembly of motor shafts 1 of multiple specifications can be achieved, improving equipment adaptability.

[0023] The connecting mechanism 3 includes a mounting plate 31 mounted on the hydraulic coupling 2. A support frame 32 is provided outside the mounting plate 31. A connecting top plate 33 is fixed to the end of the support frame 32 away from the mounting plate 31. A movable plate 34 is rotatably mounted at the bottom end of the connecting top plate 33. At least six adjusting plates 37 are slidably arranged below the movable plate 34 to fix the motor shaft 1. The frame structure combined with the multi-directional adjusting plates 37 design ensures uniform force distribution during clamping and avoids shaft deformation.

[0024] Furthermore, a guide groove 3101 is provided in the mounting plate 31, and a movable block 36 is slidably disposed in the guide groove 3101. The top end of the movable block 36 is fixedly connected to the bottom end of the adjusting plate 37. The cooperation between the guide groove 3101 and the movable block 36 restricts the movement trajectory of the adjusting plate 37, prevents clamping deviation, and improves positioning accuracy.

[0025] Furthermore, at least six sets of movable blocks 36 are provided, and the six sets of movable blocks 36 are circumferentially distributed in the guide groove 3101 with the center of the mounting plate 31 as the center. The six sets of symmetrically distributed movable blocks 36 form a ring clamping array, realizing uniform force on the motor shaft 1 in the circumference and reducing the risk of local stress concentration.

[0026] Furthermore, each adjusting plate 37 has a connecting post 38 fixed to its top, and the movable plate 34 has a strip groove 35. Each connecting post 38 contacts the inner wall of a strip groove 35. The inclined surface transmission design of the strip groove 35 and the connecting post 38 converts rotational motion into radial displacement, simplifying the operation complexity.

[0027] Furthermore, each adjusting plate 37 has a rubber pad 371 fixed to its outer wall near the center. The rubber pad 371 provides cushioning during clamping, preventing damage to the shaft surface caused by direct metal-to-metal contact and extending the service life of the motor shaft 1.

[0028] Furthermore, a worm gear disk 39 is fixed to the outer wall of the movable disk 34, and a mounting bracket 310 is fixed to the outer wall of the mounting disk 31. A worm 311 is rotatably mounted inside the mounting bracket 310, and the worm 311 meshes with the worm gear disk 39. The worm gear transmission has a self-locking characteristic, automatically locking after clamping to prevent loosening and ensuring the reliability of the connection during high-speed operation.

[0029] Furthermore, a handle 312 is fixed to one end of the worm gear 311. This lowers the operational threshold and enables quick one-handed assembly and disassembly through mechanical force amplification, thereby improving maintenance efficiency.

[0030] In actual operation, the working process of this hydraulic coupling connection device is as follows: The operator inserts the end of the motor shaft 1 into the connecting mechanism 3 of the hydraulic coupling 2. At this time, the mounting plate 31 forms a stable support structure with the connecting top plate 33 through the support frame 32, and the movable plate 34 maintains its initial position below the connecting top plate 33. The six adjusting plates 37 are radially distributed along the guide groove 3101 through the movable block 36, and the connecting post 38 at the top of each adjusting plate 37 is embedded in the strip groove 35 of the movable plate 34.

[0031] Rotating the handle 312 clockwise causes the worm gear 311 to rotate within the mounting bracket 310, and the worm wheel 39 meshing with it then drives the movable plate 34 to perform a circular motion. Due to the inclined contact relationship between the slot 35 and the connecting column 38, the rotational motion of the movable plate 34 is converted into the radial inward sliding of the adjusting plate 37. The six sets of adjusting plates 37 converge towards the center synchronously, and the rubber pads 371 on their inner walls gradually adhere to the outer wall of the motor shaft 1, achieving non-destructive clamping through the elastic deformation of the rubber pads 371. When the adjusting plates 37 completely fix the motor shaft 1, the self-locking characteristics of the worm gear 311 and the worm wheel 39 automatically take effect, preventing the clamping force from weakening due to vibration.

[0032] During disassembly, rotating handle 312 counterclockwise causes the movable disc 34 to rotate in the opposite direction, expanding the adjusting plate 37 outward along the guide groove 3101. The rubber pad 371 then detaches from the surface of the motor shaft 1, allowing for quick removal of the shaft. The entire process utilizes the transmission ratio of the worm gear mechanism to achieve labor-saving operation. The symmetrical distribution of the six adjusting plates 37 ensures concentric positioning of motor shafts 1 with different diameters. The cooperation between the guide groove 3101 and the movable block 36 ensures that the adjusting plate 37 always moves radially, preventing skewing. This mechanical transmission ratio enables labor-saving operation, facilitates rapid adaptation to motor shafts 1 with different diameters, and the guiding structure prevents skewing of the adjusting plate 37, improving assembly and disassembly efficiency, reducing maintenance costs, and combining ease of operation with reliable connection.

[0033] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
