Description
Technical Field
[0001] The utility model belongs to the field of grinding equipment, in particular to a hollow rotor edge grinding device. Background Art
[0002] In the field of modern industrial manufacturing, the manufacturing and processing technology of hollow rotors plays a vital role, especially in application scenarios with high precision requirements. Hollow rotors are widely used in a variety of mechanical and electrical equipment, such as motors, turbines and other rotating equipment. The performance and quality of these rotors directly affect the efficiency and reliability of the entire equipment. Among them, the treatment of the rotor edge, especially the scraping process, is crucial to ensure the balance and performance of the rotor.
[0003] Traditionally, the edge scraping process of hollow rotors mainly relies on manual or ordinary mechanical structures for grinding. This method can achieve the purpose of edge processing to a certain extent, but it has several significant limitations. First, manual grinding lacks consistency and precision and is easily affected by the operator's skill level and physical condition. Second, traditional mechanical grinding systems are usually inflexible and difficult to adapt to complex or irregular edge shapes. These limitations not only affect the processing efficiency, but also the final quality of the rotor.
[0004] In recent years, machine vision technology has made significant progress in industrial automation. Machine vision systems are able to capture images through high-resolution cameras and use advanced image processing algorithms to accurately identify and analyze the features of objects.

In the process of edge scraping of hollow rotors, machine vision technology has the potential to provide a more efficient and accurate automation solution. Through real-time visual monitoring, the shape and state of the edge can be accurately identified, and the automated grinding equipment can be guided to perform precise scraping operations. Therefore, there is an urgent need for an automated grinding equipment that can flexibly adjust the grinding action according to the feedback of the visual system. Utility Model Content

[0024] The utility model is further described below according to the embodiments:
[0025] Example: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is the front view of the rotor bracket of the utility model. Figure 2 This is a top view of the overall structure of the utility model. Figure 3 This is a side view of the overall structure of the utility model. Figure 4 It is a top view of the hollow rotor replacement state of the overall structure of the utility model, including a rotor bracket 1, a hollow rotor 2, a grinding mechanism 3 and a controller. The controller is electrically connected to the grinding mechanism 3 to automatically control the various components of the grinding mechanism 3. Specifically, the grinding mechanism 3 is electrically connected to the visual module and is connected and controlled with the controller. According to the signal sent by the visual module, multiple components of the grinding mechanism 3 can respond to complete automatic control; the following is a specific description: In the embodiment, the rotor bracket 1 includes two brackets and a base 103 on the left and right sides, the left bracket includes a first shaft rod 101, a first hollow shaft 1012 and a first support cylinder 1013, and the right bracket The second shaft rod 102 includes a second hollow shaft 1022 and a second support tube 1023. The first shaft rod 101 and the second shaft rod 102 are both fixed to the base 103. The top side of the first shaft rod 101 is fixed to the first hollow shaft 1012, and the first hollow shaft 1012 is fixed to the first support tube 1013. Similarly, the top side of the second shaft rod 102 on the other side is fixed to the second hollow shaft 1022, and the second hollow shaft 1022 is fixed to the second support tube 1023. The second shaft rod 102 is slidably fixedly connected to the base slideway 1051 provided on the sliding base 105 through the slider 1024. The reason for adopting this structure can be referred to Figure 4 When the slider 1024 slides to the right, the hollow rotor 2 can be taken out more conveniently.
[0026] refer to Figure 4 in the form of Figure 4It is a preferred connection method. In the figure, the first shaft 101 is axially connected to the base 103 through the first main shaft 104, so that the first shaft 101 can rotate at least 90 degrees around the first main shaft 104, which is convenient for the replacement of the hollow rotor 2; in another preferred solution, the sliding base 105 also includes a sliding base motor, which is used to actively control the position of the slider 1024 to replace manual operation to complete the bidirectional movement of the right bracket.
[0027] The first shaft 101 is connected to the first hollow shaft 1012 by a rotating shaft, and the rotating shaft is driven by the first active motor 1011, and / or the second shaft 102 is also connected to the second hollow shaft 1022 by a rotating shaft, and the rotating shaft is driven by the second active motor 1021. With this structure, the two motors can actively rotate the hollow rotor 2, so that the hollow rotor 2 as a whole can be actively rotated, and the rotating hollow rotor 2 cooperates with the grinding wheels set on both sides to effectively grind; further, it is necessary to use the first support tube 1013 and the second support tube 1023 in combination. The material of the first support tube 1013 and the second support tube 1023 can generally be a rigid material with a soft outer surface, such as rubber or a hard foam structure. Only by setting the above-mentioned support structure can the hollow rotor 2 be able to rotate stably and at a uniform speed to avoid the hollow rotor 2 from losing rotation or vibrating and deviating during the grinding process; a preferred structure can refer to Figure 5 , Figure 5 It is a schematic diagram of the local structure of the first support cylinder 1013. In the figure, a plurality of fluid ports are provided on the top of the first hollow shaft 1012. The first hollow shaft 1012 is connected to a fluid source. The first hollow shaft 1012 can pass fluid into the first support cylinder 1013 through the action of the plurality of fluid ports. Therefore, the first support cylinder 1013 should be a hollow cavity structure. The same structure is applied to the second support cylinder 1023. The advantage of adopting this structure is that when it is necessary to generate a supporting force for the hollow rotor 2, fluid is passed into the two support cylinders. When it is not necessary to generate a supporting force, the internal fluid of the two support cylinders is discharged (by a fluid pump recovery or other common means), so as to facilitate the removal of the hollow rotor 2.

This structure allows the first grinder 3012 and the second grinder 3022 to adjust the distance forward and backward. This distance adjustment can be done manually or by setting a power mechanism (for example, Cylinders, electric cylinders, hydraulic cylinders and other equipment) are connected to the controller for automatic control to ensure that the position is selected more accurately when grinding the hollow rotor 2 to avoid excessive or insufficient scraping of glue; in another preferred structure, two slide rails are further arranged above (or inside) the first slider 3011 and the second slider 3021, and the first push block 3014 and the second push block 3024 are respectively arranged above the slide rails, and the sides of the first push block 3014 and the second push block 3024 are respectively fixedly connected and controlled by the first power cylinder 3013 and the second power cylinder 3023, and the first The power cylinder 3013 and the second power cylinder 3023 can be electric cylinders, air cylinders or hydraulic cylinders. Preferably, the first power cylinder 3013 and the second power cylinder 3023 can be automatically controlled by connecting through a controller. When the first power cylinder 3013 and the second power cylinder 3023 are working, the first grinder 3012 and the second grinder 3022 will move left and right at the current position, so that the two grinders can select the position relative to the hollow rotor 2 when grinding more accurately, so as to effectively perform the scraping operation, and at the same time, the scraping offset can be dynamically adjusted according to different needs.
[0029] At least one visual module is also provided on the base 305 for collecting the position, edge information and grinding results of the hollow rotor 2, preferably including a first visual module 303 and a second visual module 304 to monitor the left and right sides of the hollow rotor 2 respectively, the first visual module 303 and the second visual module 304 are connected to the controller, and the collected image results are analyzed to form a signal to be sent to the power mechanism (determining the front and rear positions of the grinders) and the first power cylinder 3013 and the second power cylinder 3023 provided by the first grinder 3012 and the second grinder 3022, so as to automatically adjust the positions of the first grinder 3012 and the second grinder 3022 to determine the optimal grinding posture.
[0030] A preferred structure also includes a first nozzle 108 and a second nozzle 109, and the two nozzles are respectively aimed at the left and right sides of the hollow rotor 2 to deal with the situation where the temperature is too high or flushing is required during the grinding process; another preferred structure also includes a first air outlet 106 and a second air outlet 107, both of which are connected to the air source to cool the hollow rotor 2 or blow away excess scraping glue debris, and the first nozzle 108, the second nozzle 109, the first air outlet 106 and the second air outlet 107 can all be automatically activated by a temperature sensor or other sensing equipment.
