Description

Technical Field

[0001] This invention relates to the field of turbine blade technology, specifically to a turbine runner blade processing equipment. Background Technology

[0002] In the field of hydropower equipment manufacturing, turbine runner blades are the core components that directly convert the kinetic energy of water into mechanical energy. The surface quality and profile accuracy of the blades directly affect the working efficiency, cavitation resistance and service life of the turbine. The existing patent application number 202020291792.3 describes a turbine blade processing equipment. A first guide rail is mounted on the upper end of the base, and a slider that can slide along the first guide rail is mounted on the first guide rail. A first cylinder is mounted on the lower end of the base, and a first hydraulic rod connects the first cylinder and the slider. A loading box is mounted on the upper end of the slider. A second cylinder is mounted on a first mounting plate, and a second hydraulic rod passes through the second cylinder. A first mounting seat is mounted on the second hydraulic rod. A second guide rail for sliding on the first mounting seat is provided on a third mounting seat. A third cylinder is mounted on the upper end of the first mounting seat, and a third hydraulic rod passes through the first mounting seat on the third cylinder. A grinding box is mounted on the third hydraulic rod. A motor is mounted on the outer wall of the grinding box, and a rotating shaft is mounted inside the grinding box. A roller is sleeved on the outer circumference of the rotating shaft, and a grinding bushing is sleeved on the outer circumference of the roller. Traditional grinding methods often use grinding wheels to grind the surface of turbine runner blades. Since the surface of the runner blades is curved, excessive contact force can easily damage the complex curved surface of the blades. Traditional sandblasting grinding methods are fixed in position during the grinding process, making it inconvenient to adjust in real time according to the different curvatures of the runner blades. In addition, a large amount of dust is generated during the grinding process. The dust is directly discharged and pollutes the environment, and can also be inhaled by people, causing health damage. Therefore, we propose a turbine runner blade processing equipment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a turbine runner blade processing equipment. This equipment replaces the traditional grinding wheel grinding method with an adjustable position sandblasting method, which causes damage to the curved surface of the runner blade due to excessive contact force. This makes the equipment more suitable for different curved surfaces of turbine runner blades. The use of a dustproof shell in conjunction with a negative pressure fan can block and filter the dust generated during the grinding process. Furthermore, the material leakage trough and collection box can collect abrasive particles for subsequent use, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a turbine runner blade processing equipment, comprising a worktable, a grinding and polishing unit, and an adjustment unit; Workbench: A top frame is provided on the top surface. The bottom ends of the front and rear sides of the top frame are fixed with baffles and their bottom ends are fixed to the top surface of the workbench. The top surface of the workbench is provided with a protective unit. Grinding and polishing unit: includes limiting blocks, limiting grooves, brackets, main linear motors, placement racks, sandblasting guns and solenoid valves. The limiting grooves are formed on the inner wall of the top frame. The left and right sides of the brackets are fixed with limiting blocks that are slidably installed with the limiting grooves. The main linear motors are fixed in the grooves on the front and rear sides of the brackets. The surface of the main linear motor's moving part is connected to the top of the placement rack. The surface of the placement rack is snapped with a sandblasting gun. The feed pipe of the sandblasting gun extends out of the top surface of the top frame and is equipped with a solenoid valve. Adjustment unit: includes frame, motor, support platform and discharge chute. The frame is fixed in the middle of the top surface of the workbench. The motor is fixed on the bottom surface of the frame. The output shaft of the motor is fixedly connected to the bottom surface of the support platform. The support platform is located on the top surface of the workbench. The discharge chute is inclined from the inside to the outside and opened on both sides of the support platform surface. The system also includes a control box, which is located on the right side of the top frame. The input terminals of the main linear motor, sandblasting gun, solenoid valve, and motor are electrically connected to the output terminal of the control box, and the input terminal of the control box is electrically connected to the output terminal of an external power supply.

[0005] The system uses a motor to drive the turbine runner blades placed on the top of the support platform to rotate, and coordinates with the main linear motor to adjust the position of the sandblasting gun. The solenoid valve is connected to an external sandblasting machine and controls the amount of sprayed material in real time, thereby improving the grinding and polishing effect on different turbine runner blades.

[0006] Furthermore, the grinding and polishing unit also includes an electric telescopic rod, a distance sensor, a detection camera, and a frame. The electric telescopic rod is fixed to the middle of the top surface of the top frame, and its bottom end is connected to the middle of the top surface of the support. The distance sensor is installed on the front side of the support. The frame is fixed to the surface of the placement frame, and a detection camera is inserted and installed inside the frame. The input ends of the electric telescopic rod and the detection camera are electrically connected to the output end of the control box, and the output end of the distance sensor is electrically connected to the input end of the control box. Activating the electric telescopic rod drives the sandblasting gun to rise and fall, and, in conjunction with the distance sensor, precisely adjusts the height of the sandblasting gun. The detection camera inside the frame can acquire images of the grinding and polishing of the turbine runner blades, allowing the sandblasting volume to be adjusted based on the detection results.

[0007] Furthermore, the adjustment unit also includes an arc-shaped clamping plate, an adjustment seat, a main screw, an adjustment groove, an electromagnet, and a brush slip ring. The adjustment groove is formed on both sides of the support surface. The main screw is rotatably installed inside the adjustment groove. The main screw is threadedly connected to the screw hole on the surface of the adjustment seat that slides inside the adjustment groove. An arc-shaped clamping plate is fixed on the top surface of the adjustment seat. There are two electromagnets, which are respectively installed in the grooves on the front and rear sides of the top surface of the support. The brush slip ring is set on the top surface of the worktable. The input end of the electromagnet is electrically connected to the output end of the brush slip ring, and the input end of the brush slip ring is electrically connected to the output end of the control box. The rotating main screw drives the arc-shaped clamping plate on the top surface of the adjustment seat to clamp and fix the outer side of the turbine runner blade. At the same time, the electromagnet generates magnetism when energized to increase the stability of the turbine runner blade placement, while the brush slip ring ensures that the support provides power to the electromagnet during the rotation of the support.

[0008] Furthermore, the adjustment unit also includes a plate frame, a limiting plate, a top plate, a lifting rod, and a secondary screw. The top plate is disposed on the top surface of the arc-shaped clamping plate, and the secondary screw is installed on the top surface of the top plate. The lifting rod is slidably installed with the rod groove on the outer side of the arc-shaped clamping plate. The screw hole on the surface of the lifting rod is threadedly connected to the secondary screw. The top of the lifting rod is fixed with a plate frame, and the limiting plate is slidably installed inside the plate frame. The rotating secondary screw can adjust the height of the plate frame and, in conjunction with the sliding limiting plate inside, engage the outer side of the turbine runner blades, further improving the stability of the turbine runner blade placement.

[0009] Furthermore, the adjustment unit also includes a positioning column, mounting bolts, and mounting holes. The mounting holes are located in the middle of the top surface of the support platform. The bottom surface of the positioning column is fixed with mounting bolts, which are threadedly connected to the mounting holes at corresponding positions. The mounting bolts are threadedly installed in the mounting holes to fix the positioning column, thus enabling the center hole positioning of the turbine runner blades.

[0010] Furthermore, the protective unit includes a material leakage trough, a collection box, a stop bar, a box frame, a secondary linear motor, support rods, and a dustproof shell. The material leakage trough is evenly and obliquely arranged on the front and rear sides of the top surface of the workbench. The box frame is fixed to the bottom surface of the workbench, and the collection box is slidably placed inside the box frame. A stop bar is rotatably installed on the front side of the box frame. The secondary linear motor is fixed to the left side of the top frame. The surface of the secondary linear motor's moving part is provided with two corresponding support rods, and the other ends of the two support rods are respectively fixed to the surfaces of two corresponding dustproof shells. The dustproof shells slide against the surface of the top frame. The input end of the secondary linear motor is electrically connected to the output end of the control box. The rotating stop bar fixes the collection box inside the box frame. In this way, the abrasive and waste generated during grinding and polishing enter the interior of the collection box through the material leakage trough for subsequent collection and processing. The secondary linear motor drives the dustproof shell to rise and fall, which can prevent dust from scattering during the grinding and polishing process of the turbine runner blades, thus preventing environmental pollution and personnel injury.

[0011] Furthermore, the protective unit also includes a filter housing, a plate groove, a mesh frame, a filter screen, a negative pressure fan, and a support plate. The filter housing is disposed on the surface of the dustproof housing, and negative pressure fans are evenly installed on the surface of the filter housing. A plate groove is formed at the bottom end of the surface of the filter housing. A mesh frame is fixed on both sides of the top surface of the support plate, and a filter screen is inserted into the mesh frame. The support plate is installed on the bottom surface of the filter housing and is inserted into the plate groove accordingly. The input end of the negative pressure fan is electrically connected to the output end of the control box. The support plate is inserted into the plate groove to install the filter screen inside the mesh frame into the inside of the filter housing and is fixed with bolts. The negative pressure fan can draw the dust generated by grinding and polishing into the inside of the filter housing for filtration to prevent dust from scattering.

[0012] Furthermore, the protective unit also includes a protective shell, a bidirectional lead screw, a cleaning scraper, and a rotating wheel. The bidirectional lead screw is rotatably installed inside two corresponding front and rear baffles. A rotating wheel is provided at the front end of the bidirectional lead screw. The threads at both ends of the bidirectional lead screw are opposite. The cleaning scraper has two screw holes on its surface that are threadedly connected to the bidirectional lead screw. The cleaning scraper slides against the top surface of the workbench. The protective shell is located between the two corresponding front and rear baffles and outside the bidirectional lead screw. Rotating the rotating wheel drives the bidirectional lead screw to rotate, so that the cleaning scraper cleans the waste and abrasive accumulated on the surface of the workbench.

[0013] Furthermore, it also includes transparent observation windows and supplementary lights. There are two transparent observation windows, which are respectively installed on the surfaces of two dustproof shells. There are two supplementary lights, which are respectively installed on the left and right sides inside the top frame. The input end of the supplementary lights is electrically connected to the output end of the control box. The supplementary lights can provide illumination during the process of personnel looking through the transparent observation windows to observe the processing of the turbine runner blades, so as to solve the problem of insufficient light.

[0014] Furthermore, it also includes a dust sensor, which is installed on the top surface of the top frame. The detection probe of the dust sensor is located inside the top frame, and the output terminal of the dust sensor is electrically connected to the input terminal of the control box. The dust sensor can detect the amount of dust inside the dustproof housing, thereby facilitating the adjustment of the power of the negative pressure fan based on the amount of dust.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This turbine runner blade processing equipment has the following advantages: 1. By using a motor to drive the turbine runner blades placed on the top surface of the support to rotate, and cooperating with the main linear motor to adjust the position of the sandblasting gun, while the electric telescopic rod drives the sandblasting gun to rise and fall, and with the help of the set distance sensor to accurately adjust the height of the sandblasting gun, the solenoid valve is connected to the external sandblasting machine and controls the amount of sprayed material in real time, thereby improving the grinding and polishing effect on different turbine runner blades.

[0016] 2. The rotating main screw drives the arc-shaped clamping plate on the top surface of the adjusting seat to clamp and fix the outer side of the turbine runner blades. It also works with the sliding limit plate inside to snap the outer side of the turbine runner blades, so as to be suitable for the installation of turbine runner blades of different specifications. At the same time, the electromagnet generates magnetism when energized to increase the stability of the turbine runner blades.

[0017] 3. The abrasive and waste generated during grinding and polishing can be fed into the collection box through the opening of the material leakage trough. The rotating wheel drives the bidirectional lead screw to rotate, which causes the cleaning scraper to clean the waste and abrasive accumulated on the surface of the workbench, so as to facilitate subsequent collection and processing.

[0018] 4. The dust cover can be raised and lowered by the auxiliary linear motor to prevent dust from scattering during the grinding and polishing process of the turbine runner blades. The dust is then filtered by the negative pressure fan and the filter screen inside the filter cover to prevent environmental pollution and personal injury. Attached Figure Description

[0023] The working principle of the turbine runner blade processing equipment provided by this invention is as follows: First, the mounting bolts 3.17 and mounting holes 3.18 are threaded together to fix the positioning column 3.16. The turbine runner blade is placed on the top surface of the support 3.3 and the center hole is inserted into the positioning column 3.16. The rotating main screw 3.7 drives the arc-shaped clamping plate 3.5 on the top surface of the adjusting seat 3.6 to clamp and fix the outer side of the turbine runner blade. At the same time, the rotating auxiliary screw 3.15 can adjust the height of the plate frame 3.11 and cooperate with the sliding limit plate 3.12 inside it to clamp the outer side of the turbine runner blade. This system is designed for installation of turbine runner blades of various specifications. Finally, an electromagnet 3.9 is energized to generate magnetism, increasing the stability of the turbine runner blades. A brush slip ring 3.10 ensures that the support platform 3.3 provides power to the electromagnet 3.9 during rotation. After the turbine runner blades are installed, the auxiliary linear motor 4.5 is activated, driving the dust cover 4.7 to cover the top surface of the worktable 1. Motor 3.2 drives the turbine runner blades placed on the top surface of the support platform 3.3 to rotate, coordinating with the main linear motor 2.4 to adjust the position of the sandblasting gun 2.6. Simultaneously, the electric telescopic rod 2.8 is activated to raise and lower the sandblasting gun 2.6. The height of the sandblasting gun 2.6 is precisely adjusted using the ranging sensor 2.9. The detection camera 2.10 inside the frame 2.11 can acquire images of the grinding and polishing of the turbine runner blades. Based on the detection results, the solenoid valve 2.7 can be adjusted in real time to control the amount of material sprayed, thereby improving the grinding and polishing effect on different turbine runner blades. During the grinding and polishing process, the negative pressure fan 4.12 draws the dust generated during grinding and polishing into the filter housing 4.8 for filtration. Combined with the dustproof housing 4.7, this prevents dust from scattering. The rotating lever 4... .3 The collection box 4.2 is fixed inside the box frame 4.4. The abrasive and waste generated during grinding and polishing enter the collection box 4.2 through the material leakage trough 4.1 for subsequent collection and processing. The auxiliary linear motor 4.5 drives the dust cover 4.7 to rise and fall, which can prevent dust from scattering during the grinding and polishing of the turbine runner blades, thus preventing environmental pollution and personnel injury.
