Description

Technical Field

[0001] This utility model belongs to the field of application, and in particular relates to an auxiliary installation device for a gas turbine rotor. Background Technology

[0002] A gas turbine is an internal combustion engine that uses a continuously flowing gas as a working fluid to drive a high-speed rotating impeller, converting the energy of fuel into useful work. It is a type of rotating impeller-type thermal engine.

[0003] In the existing technology, the assembly of gas turbine rotors relies on manual or special fixtures. Manual assembly is difficult to control in terms of accuracy and has low efficiency. On the other hand, the existing special fixtures have low adaptability and cannot meet the assembly requirements of rotors of different sizes.

[0004] Therefore, we need to design an auxiliary installation device for gas turbine rotors to solve these problems. Utility Model Content

[0005] The problem to be solved by this utility model is to provide an auxiliary installation device for gas turbine rotors.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An auxiliary installation device for a gas turbine rotor includes a frame with two pressing mechanisms mounted on it. The output directions of the two pressing mechanisms are opposite to each other. A support mechanism is mounted on the frame between the output ends of the two pressing mechanisms and reciprocates between them. Each pressing mechanism includes a sliding frame and an adjusting cylinder. The sliding frame is slidably connected to the frame and has a push block. The adjusting cylinder is located on one side of the sliding frame and its output end is connected to the sliding frame. The support mechanism includes a mounting box with a fixing tube. A support rod is installed inside the fixing tube. A clamping assembly is fixedly mounted at one end of the support rod, and a rotating assembly and a lifting assembly are mounted at the other end.

[0008] Preferably, the frame includes a base, on which two mounting frames are provided, the pressing mechanism is fixedly mounted on the mounting frames, and a top beam is provided between the two mounting frames, with the support mechanism located below the top beam.

[0009] This configuration, using the base as a fundamental component to provide a stable support platform, and the mounting frame fixing the pressing mechanism, ensures a stable transmission path of the pressing force and prevents the mechanism from shaking and affecting the pressing accuracy. The top beam connects the two mounting frames to form a rigid frame structure, enhancing the overall strength and deformation resistance of the frame, especially when subjected to bidirectional pressing forces, reducing the elastic deformation of the frame.

[0010] Preferably, the pressing mechanism further includes a mounting bracket fixedly mounted on the mounting frame, a slide rail fixedly mounted on the mounting bracket, a slider slidably mounted on the slide rail, the slide bracket being fixedly connected to the slider, and the adjusting cylinder being connected to the mounting frame through the mounting bracket.

[0011] This design, through the combination of the mounting bracket and the slide rail, provides a high-precision guide track for the sliding frame. The low coefficient of sliding friction of the slider on the slide rail reduces resistance and wear during the movement of the sliding frame, ensuring the smoothness and repeatability of the pressing action. The adjusting cylinder is connected to the mounting frame via the mounting bracket, aligning the line of action of the driving force with the direction of the slide rail, preventing sliding frame misalignment caused by lateral forces, and further improving the accuracy of the pressing position. This structure facilitates the installation and maintenance of the adjusting cylinder, while the standardized components of the slide rail and slider reduce equipment maintenance costs.

[0012] Preferably, a first mold is fixedly provided on the push block, and a second mold is detachably provided on the first mold.

[0013] This configuration, with the first mold fixedly connected to the push block, ensures reliable transmission of pressing force. The second mold's detachable design allows for quick replacement of molds of different shapes or specifications to adapt to diverse rotor pressing needs, such as sleeves with different bore diameters and connectors of different sizes. This modular design reduces mold changeover time, improves the flexibility of the production line, and the detachable structure facilitates individual mold repair or replacement, reducing overall equipment maintenance costs.

[0014] Preferably, the support mechanism further includes a lead screw and an adjusting motor. The lead screw is rotatably connected to the frame, the adjusting motor is fixed on the frame, and its output end is connected to one end of the lead screw. A drive block is also matched and installed on the lead screw, and a slide is fixedly provided on the drive block. The mounting box is fixedly provided on the slide.

[0015] This configuration utilizes an adjustable motor to drive the lead screw, forming a lead screw-nut drive pair with the lead screw and drive block. This converts rotational motion into linear motion, achieving precise displacement control of the support mechanism. Lead screw drives offer high transmission efficiency, high positioning accuracy, and smooth transmission. Combined with servo control of the motor, the position of the support mechanism can be precisely adjusted to meet the positioning requirements of different rotors during the press-fitting process. This structure boasts a high degree of automation; the movement trajectory and speed of the support mechanism can be programmed, reducing manual intervention and improving production efficiency and consistency.

[0016] Preferably, the clamping assembly includes a lifting plate fixed to one end of the support rod, a positioning seat fixedly disposed on the lifting plate, and spinning cylinders fixedly disposed on the lifting plates on both sides of the positioning seat, with pressure rods fixedly disposed at the output ends of the spinning cylinders.

[0017] This configuration utilizes the positioning base to provide an initial positioning reference for the rotor, ensuring its positional accuracy during clamping. The simultaneous action of the pressure rods driven by the spinning cylinders on both sides allows for symmetrical clamping of the rotor, preventing deformation caused by uneven clamping force. The lifting plate adjusts the height of the clamping assembly to accommodate rotors of different heights, enhancing the equipment's versatility. The thrust of the spinning cylinders is controllable, allowing adjustment of the clamping force according to the rotor's material and size. This ensures clamping stability while preventing excessive pressure from damaging the rotor. The structure provides rapid clamping action, suitable for quick setup requirements.

[0018] Preferably, the rotating assembly includes a driven wheel fixedly mounted on the support rod, a mounting plate rotatably mounted on the support rod between the driven wheel and the fixed tube, a rotary motor fixedly mounted on the mounting plate, a drive wheel fixedly mounted at the output end of the rotary motor, and the drive wheel and the driven wheel being connected by a transmission belt.

[0019] This configuration allows the rotary motor to drive the driven wheel via the drive wheel and transmission belt, which in turn causes the support rod and its clamping components to rotate, enabling multi-angle rotation of the rotor. The rotating connection design between the mounting plate and the support rod makes the installation and maintenance of the rotating components more convenient, while the rotation angle can be precisely controlled by the motor to meet high-precision positioning requirements.

[0020] Preferably, the lifting assembly includes a fixed frame fixedly connected to the fixed tube, a connecting seat and a linkage mechanism are hinged on the fixed frame, a lifting cylinder is fixedly installed on the connecting seat, and the linkage mechanism is also hinged to the output end of the lifting cylinder and the mounting plate respectively. When the lifting cylinder extends or retracts, the support rod will reciprocate along the axial direction of the fixed tube.

[0021] This configuration allows the lifting cylinder to drive the support rod to move axially along the fixed tube via a linkage mechanism. Utilizing the lever principle of the linkage mechanism, the linear motion of the lifting cylinder is converted into smooth lifting and lowering of the support rod. Simultaneously, the lifting force is amplified or adjusted, resulting in smoother movement and greater load capacity. The articulated structure allows the linkage mechanism to flexibly adjust its angle during movement, avoiding the jamming that can occur with rigid transmission. It enables precise control of the support rod's lifting height, and in conjunction with the rotating assembly, allows for rotor position adjustment in three-dimensional space, meeting the precise control requirements for rotor attitude in complex press-fitting processes.

[0022] Preferably, two limiting plates are fixedly provided on the slide, and the two limiting plates are parallel to each other.

[0023] This configuration, by fixing the limiting plate to the slide, mechanically limits the sliding stroke of the slide, improving stability during movement and ensuring the safety of equipment operation. The two parallel limiting plates ensure the lateral positioning accuracy of the slide during movement, preventing it from deviating from the guide rail, further guaranteeing the motion stability and positioning accuracy of the pressing mechanism. This structure is simple, reliable, and has low maintenance costs.

[0024] Preferably, the first mold is provided with a connecting hole, and the second mold is provided with a connecting post, wherein the connecting hole and the connecting post are connected by a threaded engagement.

[0025] This configuration, with the first and second molds connected by threads, ensures a rigid connection between the molds during pressing, preventing loosening due to vibration or pressure and ensuring pressing accuracy. The high coaxiality of the threaded connection guarantees the positional accuracy of the second mold during installation, thus ensuring the dimensional consistency of the pressed rotor. Furthermore, the threaded connection has moderate requirements for machining precision, reducing mold manufacturing costs and facilitating quick mold changes. It also features a simple structure, strong connection, and easy assembly and disassembly, improving efficiency.

[0026] The advantages and positive effects of this utility model are:

[0027] This invention utilizes two opposing pressing mechanisms to achieve bidirectional synchronous pressing, improving the assembly efficiency of rotor processing. Different combinations of the first and second molds can meet various pressing requirements. The reciprocating movement design of the support mechanism allows for flexible adjustment according to the size and characteristics of the rotor to be pressed, enhancing the equipment's adaptability to rotors of different specifications. The sliding frame is slidably connected to the machine frame, and with the assistance of the adjusting cylinder, it can precisely control the movement direction and pressing force of the push block. By adjusting the stroke or pressure parameters of the adjusting cylinder, the accuracy requirements of different pressing processes can be met. Furthermore, the sliding connection structure facilitates maintenance and repair. The cooperation between the fixed tube and the support rod allows for multi-dimensional adjustment of the rotor's position, improving work efficiency and assembly accuracy.

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] Example: Figures 1-8 As shown, an auxiliary installation device for a gas turbine rotor includes a frame 1, on which two pressing mechanisms 3 are mounted. The output directions of the two pressing mechanisms 3 are opposite. A support mechanism 2 is mounted on the frame 1 between the output ends of the two pressing mechanisms 3. The support mechanism 2 reciprocates between the two pressing mechanisms 3. The pressing mechanism 3 includes a sliding frame 32 and an adjusting cylinder 30. The sliding frame 32 is slidably connected to the frame 1 and is provided with a push block 35. The adjusting cylinder 30 is located on one side of the sliding frame 32 and its output end is connected to the sliding frame 32. The support mechanism 2 includes a mounting box 204. A fixing tube 206 is provided on the mounting box 204. A support rod 207 is provided inside the fixing tube 206. A clamping component is fixedly mounted at one end of the support rod 207, and a rotating component and a lifting component are provided at the other end.

[0043] Two opposing pressing mechanisms 3 drive the sliding frame 32 via adjusting cylinder 30, which in turn drives the push block 35 to perform pressing operations. Meanwhile, the reciprocating movement of the support mechanism 2 can precisely transport the rotor 4 to the pressing station, achieving stable support and positioning of the rotor 4 during the pressing process. The mounting box 204 in the support mechanism 2 serves as a carrier, and the fixed tube 206 and support rod 207 on it provide the mounting base for the clamping assembly, rotating assembly, and lifting assembly, forming a multi-dimensional adjustable rotor 4 fixing system. This system works in conjunction with the pressing mechanism 3 to ensure smooth pressing operations.

[0044] The frame 1 includes a base 11, on which two mounting frames 12 are provided. The pressing mechanism 3 is fixedly mounted on the mounting frames 12. A top beam 13 is also provided between the two mounting frames 12, and the support mechanism 2 is located below the top beam 13.

[0045] The base 11 serves as the fundamental support component of the entire equipment, bearing the weight of all components, including the mounting frame 12 and the pressing mechanism 3, as well as the pressure generated during operation. The two mounting frames 12 provide fixed mounting points for the pressing mechanism 3, ensuring its stability. The top beam 13 connects the two mounting frames 12, enhancing the overall rigidity of the frame 1, limiting the vertical movement range of the support mechanism 2, and providing a guiding reference for the lateral movement of the support mechanism 2, ensuring the stability and accuracy of the support mechanism 2 when moving between the two pressing mechanisms 3. A light fixture 14 is also installed on the top beam 13, providing sufficient illumination for the equipment and facilitating the assembly of the impeller 42 and the shaft.

[0046] The pressing mechanism 3 also includes a mounting bracket 31 fixedly mounted on the mounting frame 12. A slide rail 33 is fixedly mounted on the mounting bracket 31, and a slider 34 is slidably mounted on the slide rail 33. The sliding frame 32 is fixedly connected to the slider 34, and the adjusting cylinder 30 is connected to the mounting frame 12 through the mounting bracket 31.

[0047] Mounting bracket 31 is fixed on mounting frame 12. Its upper slide rail 33 and slider 34 form a linear guide structure, providing a moving track for sliding frame 32. One end of adjusting cylinder 30 is connected to mounting bracket 31, and the other end is connected to sliding frame 32. When adjusting cylinder 30 extends or retracts, the driving force is transmitted to sliding frame 32 through mounting bracket 31. Sliding frame 32, with the help of slider 34 sliding on slide rail 33, converts the extension and retraction motion of adjusting cylinder 30 into precise linear motion, thereby driving push block 35 to perform pressing operation, realizing precise control of pressing position and force.

[0048] A first mold 36 is fixedly mounted on the push block 35, and a second mold 38 is detachably mounted on the first mold 36.

[0049] The pusher block 35 is fixedly connected to the first mold 36, transmitting the thrust of the sliding frame 32 to the mold to press-fit the rotor 4. The second mold 38, which is detachable on the first mold 36, can be replaced according to the pressing requirements of different rotors 4. The second mold 38 is installed on the first mold 36 through a connecting structure, so the first mold 36 does not need to be disassembled when replacing it, shortening the mold change time. At the same time, the second mold 38 of different specifications can cooperate with the pusher block 35 and the first mold 36, so that the pressing mechanism 3 can adapt to a variety of pressing processes.

[0050] The support mechanism 2 also includes a lead screw 202 and an adjusting motor 203. The lead screw 202 is rotatably connected to the frame 1. The adjusting motor 203 is fixed on the frame 1 and its output end is connected to one end of the lead screw 202. A drive block 220 is also matched and installed on the lead screw 202. A slide plate 201 is fixedly installed on the drive block 220. The mounting box 204 is fixedly installed on the slide plate 201.

[0051] The adjusting motor 203 is fixed to the frame 1. After starting, it drives the lead screw 202 to rotate. The threaded engagement between the lead screw 202 and the drive block 220 converts the rotational motion into linear motion. The drive block 220 drives the slide 201 of the fixed support mechanism 2 to move on the frame 1. By adjusting the forward and reverse rotation and speed control of the motor 203, the position of the support mechanism 2 between the two pressing mechanisms 3 can be precisely adjusted, so that the support mechanism 2 can accurately transport the rotor 4 to the designated position according to the pressing requirements, realizing coordinated operation with the pressing mechanism 3. Several stiffening plates 205 are also provided between the mounting box 204 and the slide 201 for reinforcement to improve the stability of the mounting box 204.

[0052] The clamping assembly includes a lifting plate 208 fixed to one end of the support rod 207, a positioning seat 209 fixedly mounted on the lifting plate 208, and spinning cylinders 210 fixedly mounted on the lifting plates 208 on both sides of the positioning seat 209. Each output end of the spinning cylinder 210 is fixedly mounted with a pressure rod 211.

[0053] The lifting plate 208 is fixed to one end of the support rod 207, providing an installation surface for the positioning seat 209 and the spinning cylinder 210. The positioning seat 209 initially positions the rotor 4, determining its horizontal position. After the spinning cylinders 210 on both sides are activated, pressure is applied to the rotor 4 through the pressure rod 211, clamping and fixing the rotor 4 onto the positioning seat 209. The lifting plate 208 can be height-adjusted under the action of the support rod 207 to accommodate rotors 4 of different heights, ensuring that the clamping assembly can stably clamp rotors 4 of various specifications, providing reliable rotor 4 fixation for the pressing operation.

[0054] The rotating assembly includes a driven wheel 216 fixedly mounted on a support rod 207, a mounting plate 213 rotatably mounted on the support rod 207 between the driven wheel 216 and the fixed tube 206, a rotary motor 212 fixedly mounted on the mounting plate 213, a drive wheel 214 fixedly mounted at the output end of the rotary motor 212, and the drive wheel 214 and the driven wheel 216 are connected by a transmission belt 215.

[0055] The rotary motor 212 is fixed on the mounting plate 213. After starting, it drives the drive wheel 214 to rotate, which in turn drives the driven wheel 216 to rotate via the transmission belt 215. The driven wheel 216 is fixedly connected to the support rod 207, thereby realizing the rotation of the support rod 207 and the clamping assembly. The rotatable connection design of the mounting plate 213 on the support rod 207 allows the rotary motor 212 and the drive wheel 214 to be flexibly adjusted in position, ensuring the tension and transmission stability of the transmission belt 215. This rotating assembly allows the rotor 4 to be adjusted to a suitable angle before pressing, meeting the angle requirements of different pressing processes for the rotor 4.

[0056] The lifting assembly includes a fixed frame 218 fixedly connected to the fixed tube 206. A connecting seat 221 and a linkage mechanism 217 are hinged on the fixed frame 218. A lifting cylinder 219 is fixedly installed on the connecting seat 221. The linkage mechanism 217 is also hinged to the output end of the lifting cylinder 219 and the mounting plate 213 respectively. When the lifting cylinder 219 extends or retracts, the support rod 207 will reciprocate along the axial direction of the fixed tube 206.

[0057] The fixed frame 218 is connected to the fixed tube 206, providing an installation base for the connecting seat 221, the linkage mechanism 217, and the lifting cylinder 219. When the lifting cylinder 219 extends or retracts, its output force is transmitted to the mounting plate 213 through the linkage mechanism 217. The hinged structure of the linkage mechanism 217 can change the direction of force transmission, causing the mounting plate 213 to drive the support rod 207 to move axially along the fixed tube 206. By controlling the extension and retraction stroke of the lifting cylinder 219, the height of the support rod 207 and the clamping assembly can be precisely adjusted, realizing the vertical position adjustment of the rotor 4. In conjunction with the clamping assembly and the rotating assembly, the rotor 4 is precisely positioned in three-dimensional space, ensuring compatibility with the pressing mechanism 3.

[0058] Two limiting plates 222 are fixedly installed on the slide 201, and the two limiting plates 222 are parallel to each other.

[0059] Two parallel limiting plates 222 are fixed on the slide 201 to provide mechanical limits for the sliding stroke of the slide 201. When the slide 201 moves under the cooperation of the lead screw 202 and the drive block 220, the limiting plates 222 cooperate with the frame 1 to ensure the stability of the slide 201's movement, ensure the safe operation of the equipment, and at the same time ensure the positional accuracy of the slide 201's movement each time, improving the stability and consistency of the pressing operation.

[0060] The first mold 36 is provided with a connecting hole 37, and the second mold 38 is provided with a connecting post 39. The connecting hole 37 and the connecting post 39 are connected by a threaded engagement.

[0061] The connecting hole 37 of the first mold 36 and the connecting post 39 of the second mold 38 are fixedly connected by a threaded engagement. The threaded connection has high connection strength and can withstand the pressure during the pressing process, ensuring that the second mold 38 will not loosen or shift during pressing. When replacing the second mold 38, disassembly and installation can be completed simply by tightening the threads. This simple operation allows for quick switching between molds of different specifications to meet diverse pressing needs, improving the equipment's versatility and production efficiency.

[0062] The working process of this embodiment is as follows: First, the mounting shaft 41 is placed into the V-groove on the positioning seat 209. Then, the rotary cylinder 210 is activated, driving the pressure rod 211 to rotate above the mounting shaft 41 and then move downwards, firmly pressing the mounting shaft 41 onto the positioning seat 209. Next, the impeller 42 to be pressed is fitted onto the mounting shaft 41, and the corresponding mold is installed on the push block 35 according to the installation process of the impeller 42. Finally, the regulating motor 203 is started, which drives the lead screw 202 to rotate. After the lead screw 202 rotates, it drives the slide 20 through the drive block 220. 1. Movement: This allows for adjustment of the position of the mounting shaft 41 on the two pressing mechanism 3 supports. Simultaneously, the rotary motor 212 rotates, driving the driven wheel 216 to rotate via the drive wheel 214 and transmission belt 215. After the driven wheel 216 rotates, the support rod 207 also rotates. The rotation of the support rod 207 drives the mounting shaft 41 to rotate via the lifting plate 208 and positioning seat 209, thus adjusting the angle of the mounting shaft 41. The lifting cylinder 219 also outputs power, driving the support shaft to move axially along the fixed tube 206 via the linkage mechanism 217, thereby adjusting the height of the lifting plate 208.

[0063] After adjustment, the adjusting cylinder 30 will drive the sliding frame 32 to move along the slide rail 33. When the sliding frame 32 moves, it will push the block 35 to drive the first mold 36 or the second mold 38 to put the impeller 42 onto the mounting shaft 41, thus completing the assembly of the rotor 4.

[0064] During installation, it is important to note that the first mold 36 is installed on the push block 35 of one of the pressing mechanisms 3. Because the mounting shaft 41 protrudes after the impeller 42 is fitted onto it, the mounting shaft 41 will enter the connecting hole 37 to avoid obstruction as the first mold 36 continuously applies pushing force after the impeller 42 is fully fitted onto the mounting shaft 41. On the other pressing mechanism 3, a second mold 38 is installed through the connecting hole 37 on the first mold 36. The second mold 38 is a push plate. When the first mold 36 presses onto one end of the mounting shaft 41, the second mold 38 will provide pushing force at the other end of the mounting shaft 41 to prevent the mounting shaft 41 from moving axially after being subjected to force. Furthermore, the pressing process and assembly quality can be monitored by detecting the pressure of the two pressing mechanisms 3.

[0065] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
