Description

Technical Field

[0001] This application belongs to the field of machinery, and particularly relates to a polishing machine for wind power bearing parts. Background Art

[0002] Wind power bearings are generally heavy and have a cage that is more than 2m long. At present, deburring and polishing of wind power bearings are both carried out manually using grinders, which wastes a lot of manpower and material resources.

[0003] If a polishing device is used for polishing, simply expanding the existing polishing machine to meet the polishing of wind power bearings, but due to the overly large internal space of the polishing machine, it is easy for the internal abrasives to tumble incompletely, that is, the effect of comprehensive polishing cannot be achieved; and a single vibration motor far from meets the required vibration effect, so generally multiple vibration motors are used for common vibration, such as Figure 1 , multiple motors use eccentric blocks to vibrate the polishing equipment, but there is also another problem at this time. The rotation of multiple motors may result in inconsistent vibration, and in this case, vibration cancellation will occur, leading to incomplete polishing or even inability to polish, etc.

[0004] Another example is the published patent (Publication No. CN103447629A), which discloses using a synchronous belt for synchronization to avoid slippage between the belt and the pulley due to overload when the chip removal on the machining surface of the burr knife is not smooth, which is beneficial to protecting the synchronous belt pulley and the burr knife; however, synchronization by means of a belt is not applicable in this polishing machine. Once overload occurs and the belt slips, the polishing effect will also be greatly reduced.

[0005] For example, the published patent (Publication No. CN211389290U) also discloses using a synchronous belt for synchronization. This published patent also has the problem that the synchronous belt will slip under overload conditions. If it is used in this technical solution, slippage will occur.

[0006] Therefore, there is an urgent need for a polishing machine that can not only meet vibration consistency and avoid vibration cancellation, but also solve the slippage phenomenon that occurs when using a synchronous belt. Summary of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Such as Figures 1-6As shown in the figure, a polishing machine for wind power bearing parts includes a base 1. The base 1 is disc-shaped and is generally placed on a supporting surface, such as the ground, a flat placement surface, etc., for supporting the whole machine. At the upper end of the base 1, there is a first spring seat 1-1. The first spring seats 1-1 are evenly distributed around the outer circle of the top surface of the base 1. A compression spring 1-2 is sleeved on the first spring seat 1-1. The upper end of the compression spring 1-2 is connected to a second spring seat 2-1. The second spring seat 2-1 is fixedly connected to the lower end of a spring plate 2-2 provided at the lower end of the outer shell 2 and is evenly distributed and corresponds to the first spring seat 1-1. On the outer surface of the outer shell 2, there are several arc-shaped rib plates 6. Inside the outer shell 2, a middle barrel 4 is fixed. The middle barrel 4 is a cylindrical shape that penetrates up and down and is concentric with the outer shell 2. The middle barrel 4 is connected to the outer shell 2 by an arc plate, and a U-shaped shape is formed at the bottom between them, which is convenient for the workpiece to roll inside. At the bottom of the middle barrel 4, there is a middle barrel flange 3-1, and a space is formed between it and the middle barrel 4. On the middle barrel flange 3-1, there are three groups of centering block assemblies 3-2. The three groups of centering block assemblies 3-2 are evenly distributed on the middle barrel flange 3-1. Inside the centering block assembly 3-2, a motor 3-3 is fixedly connected. One end of the output shaft of the motor 3-3 is connected to a first eccentric block 3-4. At one end of the first eccentric block 3-4 away from the output shaft of the motor 3-3, there is a synchronous shaft pin 3-5. The synchronous shaft pin 3-5 is movably connected to a synchronous frame 3-6. The synchronous frame 3-6 is an equilateral triangle, and each angle of the synchronous frame 3-6 is rotatably connected to each synchronous pin shaft 3-5. Through such a rotational connection method, the vibration cancellation situation caused by the independent movement of each first eccentric block 3-4 can be avoided, and the synchronous belt is replaced by the equilateral triangle synchronous frame 3-6 for synchronization, avoiding the situation of slipping of the synchronous belt due to excessive load during use;

[0034] Among them, the first eccentric block 3-4 includes a fixed end 3-4-1 and an eccentric end 3-4-2. The fixed end 3-4-1 is a rectangular block. At one end of the fixed end 3-4-1, there is a circular opening 3-4-3 adapted to the motor shaft and a long strip-shaped opening 3-4-4 penetrating the circular opening 3-4-3. On the side of the long strip-shaped opening 3-4-4, there is a through hole 3-4-5 penetrating the long strip-shaped opening. The first eccentric block 3-4 is locked through a pin in the through hole 3-4-5. The eccentric end 3-4-2 is a sector. At the lower end of its outermost side, there is a counterweight 3-4-6 for better generating the vibration effect of the equipment. The eccentric end 3-4-2 is fixedly connected to a section of the fixed end 3-4-1 away from the long strip-shaped opening 3-4-4, and a synchronous shaft pin 3-5 is provided on the eccentric end 3-4-2. The synchronous shaft pin 3-5 is inserted into the corresponding pin hole of the synchronous frame 3-6;

[0035] To achieve better effects, a second eccentric block 5 is also provided at the other end of the output shaft of the motor 3-3. The setting angle of the second eccentric block 5 is the same as that of the first eccentric block 3-4, and the fixing methods of the first eccentric block 3-4 and the second eccentric block 5 are also the same. To facilitate the adjustment of the vibration effect, no synchronizing frame 3-6 is provided between the second eccentric blocks 5. If adjustment is needed, only the angle of the second eccentric block 5 needs to be adjusted.

[0036] Working principle:

[0037] Place the workpiece and the polishing abrasive in the U-shaped groove between the middle barrel 4 and the outer shell 2. Start the motor 3-3, and the motor 3-3 drives the first eccentric block 3-4 to rotate. Due to the presence of the counterweight and the compression spring 1-2 at the bottom of the outer shell 2, rocking vibration will occur between them. And due to the presence of the synchronizing frame 3-6, vibration cancellation will not occur among the three first eccentric blocks 5. If the vibration effect needs to be adjusted, only the angle of the second eccentric block 5 needs to be adjusted. The vibration generated between multiple motors 3-3 and the first eccentric blocks 3-4 can meet the polishing work of large workpieces in the machine. By generating vibration in this way, on the one hand, the slippage of the synchronous belt is avoided, and on the other hand, the cancellation of the vibration forces in all directions is avoided.
