Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, specifically a grinding device for the production and processing of turbine castings. Background Technology

[0002] As is well known, grinding equipment for turbine casting production and processing is a device specifically used for surface treatment of turbine castings (such as turbine blades, turbine disks, etc.). It removes burrs, flash, oxide scale and machining marks from the surface of the castings through mechanical grinding, thereby improving surface finish and dimensional accuracy, and ensuring the assembly performance and service life of turbine components.

[0003] Existing grinding devices for turbine casting production and processing have significant limitations: their grinding mechanisms are usually fixedly mounted on the main body of the equipment, and their position and angle are difficult to adjust flexibly. When grinding small parts of turbine castings (such as blade roots, tenon grooves, etc.), the fixed state of the grinding mechanism limits the ability to accurately contact the grinding tool with the small area to be ground, even if the turbine is firmly clamped by the clamping mechanism. As a result, burrs, flash, and other defects in these areas cannot be effectively removed. This design flaw not only affects the surface treatment quality of turbine castings, but also reduces the applicability of the equipment due to operational limitations, significantly weakening its practical value in complex turbine processing scenarios.

The grinding mechanism includes a frame, a first bolt, a mounting frame, a bearing, a rotating block, a groove, an electric push rod, a telescopic cylinder, a motor, a connecting plate, a mounting plate, a grinding plate, and a second bolt. The frame is connected to the base plate via the first bolt, and the mounting frame is connected to the base plate via the first bolt. The top of the frame is in contact with the rotating block. One end of the rotating block is connected to one end of the mounting frame via the bearing. The groove is formed at the other end of the mounting frame. One end of the electric push rod is connected to the inner wall of the groove. The other end of the electric push rod extends into the bottom of the rotating block. The bottom of the rotating block has a groove that matches the output end of the electric push rod. One end of the telescopic cylinder is connected to the mounting frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5A grinding device for turbine casting production and processing includes a base plate 1, a support base 2, a clamping mechanism 3, and a grinding mechanism 4. The support base 2 is located at the bottom of the base plate 1, and several support bases 2 are provided. Two clamping mechanisms 3 are located at the top of the base plate 1. The grinding mechanism 4 includes a frame 5, a first bolt 6, a mounting frame 7, a bearing 8, a rotating block 9, a groove 10, an electric push rod 11, a telescopic cylinder 12, a motor 13, a connecting plate 14, a mounting plate 15, a grinding plate 16, and a second bolt 18. The frame 5 is connected to the base plate 1 via the first bolt 6, and the mounting frame 7 contacts the top of the frame 5. The rotating block... One end of block 9 is connected to one end of mounting frame 7 via bearing 8. The groove 10 is formed at the other end of mounting frame 7. One end of electric push rod 11 is connected to the inner wall of groove 10. The other end of electric push rod 11 extends into the bottom of rotating block 9. The bottom of rotating block 9 has a groove that matches the output end of electric push rod 11. One end of telescopic cylinder 12 is connected to mounting frame 7. The other end of telescopic cylinder 12 is connected to one end of motor 13. The output end of motor 13 is connected to connecting plate 14. Mounting plate 15 is connected to connecting plate 14 via second bolt 18. Grinding plate 16 is set on mounting plate 15.

[0024] Working principle: Place the equipment in the designated location, where it is stably supported by the support base 2 at the bottom of the base plate 1. Then connect the external mains power to power the equipment. During operation, as follows... Figure 1 As shown, the worker places the turbine casting in the center of the base plate 1 and secures it firmly using two symmetrically arranged clamping mechanisms 3 (including telescopic cylinders and clamping plates, etc.). Then, the worker holds the mounting frame 7, starts the motor 13, and drives the connecting plate 14, mounting plate 15 and grinding plate 16 to rotate synchronously. Then, the telescopic cylinder 12 is started to push the grinding plate 16 closer to the turbine and make contact, so that the surface of the turbine can be ground.

[0025] When grinding small parts of the turbine, the operating procedure is as follows: Figure 1 As shown, the electric push rod 11 in the groove 10 is activated, causing its output end to separate from the groove at the bottom of the rotating block 9; then the rotating block 9 connected to the mounting frame 7 is rotated around the bearing 8, causing the rotating block 9 to detach from the frame 5. The mounting frame 7 is then separated from the frame 5 and adjusted to a position that is easy to operate. The rotating block 9 is then reset to its initial state. After that, the operator uses a screwdriver to unscrew the second bolt 18, causing the mounting plate 15 to separate from the connecting plate 14, thereby removing the grinding plate 16 and replacing it with a special grinding plate or grinding roller suitable for narrow spaces (this device is equipped with various models of grinding parts, and the replacement method is a conventional operation in the field, which will not be described here).

[0026] After the replacement is completed, use an external screwdriver to unscrew the first bolt 6, separate the frame 5 from the base plate 1, hold the mounting frame, start the motor 13, so that the rotating grinding plate 16 accurately contacts the turbine to be ground, and complete the fine grinding of the narrow area.

[0027] To improve the stability of the turbine casting during the grinding process, this embodiment arranges two clamping mechanisms 3 symmetrically on the top of the base plate 1. This symmetrical layout allows the clamping force to be applied evenly from both sides of the turbine, preventing the casting from shaking or shifting during grinding due to force deviation. It is especially suitable for positioning irregular curved surface components such as turbine disks and blades. At the same time, the symmetrical structure ensures that the turbine center and the working center of the grinding mechanism 4 maintain a precise correspondence, reducing grinding accuracy errors caused by positional deviations. Combined with the anti-slip layer at the bottom of the support base 2, it forms a double guarantee from casting fixation to overall equipment stability, providing a reliable foundation for subsequent efficient grinding.

[0028] To improve the convenience and accuracy of equipment operation, this embodiment has a controller 17 installed on the front of the base plate 1. The controller 17 is electrically connected to the clamping mechanism 3. The operator can directly control the operation of the clamping mechanism 3 through the controller 17 without manually operating the clamping components. It can accurately control the clamping force and opening and closing range, and is suitable for turbine castings of different sizes. This integrated control design simplifies the operation process and reduces the error of manual intervention. Especially in batch grinding operations, the clamping parameters can be quickly switched through the controller 17 to improve work efficiency. At the same time, a control interface is reserved for possible future functional expansion, which enhances the practicality of the equipment.

[0029] To enhance the anti-slip performance of the equipment during grinding operations, an anti-slip layer is added to the bottom of the support base 2 in this embodiment. The anti-slip layer is fixedly connected to the bottom of the support base 2. The anti-slip layer can effectively increase the friction between the support base 2 and the ground, preventing the equipment from slipping due to vibrations caused by motor operation and component movement during grinding. Especially when applying grinding force to the turbine casting, it can ensure the overall stability of the equipment. The fixed connection design ensures that the anti-slip layer is not easy to fall off and can maintain the anti-slip effect for a long time. Combined with the support function of the support base 2, it further improves the safety and reliability of the equipment during operation.

[0030] To further enhance the anti-slip effect of the support base 2, in this embodiment, the anti-slip layer at the bottom of the support base 2 is specially made of rubber. The rubber material itself has a high coefficient of friction, which can significantly increase the contact friction between the support base 2 and the ground, effectively suppressing the slippage caused by the vibration generated by the motor operation and component movement during the grinding operation. At the same time, the rubber has good elasticity and deformation ability, which can conform to the slight unevenness of the ground and improve contact stability. Its wear-resistant and anti-aging properties ensure the long-term stability of the anti-slip effect. Combined with the fixed connection structure of the support base 2, it provides a reliable guarantee for the overall operational safety of the equipment.

[0031] To enhance the stability and reliability of the connections between components, in this embodiment, several first bolts 6 and several second bolts 18 are provided. The multiple first bolts 6 are evenly distributed at the connection between the frame 5 and the base plate 1, and the frame 5 and the base plate 1 are tightly fitted together through multi-point fastening, so as to avoid the frame from loosening due to vibration during the grinding operation. The multiple second bolts 18 are connected to the mounting plate 15 and the connecting plate 14 respectively, so as to ensure that the grinding plate 16 does not shift or fall off during high-speed rotation grinding. This multi-bolt distribution design can distribute the force on the connection, reduce the load on a single bolt, significantly improve the connection strength and durability, and provide structural protection for the long-term stable operation of the equipment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
