Abstract
Description
Technical Field
[0001] This utility model relates to the field of spindle technology, specifically to a water-cooled electric spindle that achieves self-cleaning. Background Technology
[0002] The cutting tool is installed inside the spindle, and the spindle drives the cutting tool to process the mechanical parts, which generates a lot of heat. Cutting fluid needs to be continuously sprayed to cool the cutting tool in order to ensure the quality of machining.
[0003] When the external spindle is running, the cutting fluid is sprayed out from the rotary joint to directly cool the tip of the tool, which greatly improves the tool's service life. However, since the cutting fluid contains dust or iron filings, these dust or iron filings will enter and remain inside the spindle, making it impossible to quickly clean the coolant and thus affecting the spindle's cooling effect to some extent. Utility Model Content
[0004] The purpose of this invention is to provide a self-cleaning water-cooled electric spindle to solve the problem that dust or iron filings can enter and remain inside the spindle, making it impossible to quickly clean the coolant and thus affecting the spindle's cooling effect to some extent.
[0005] This utility model provides the following technical solution: a self-cleaning water-cooled electric spindle, including a spindle body; a cooling chamber is provided on the inner side of the spindle body, a cooling assembly is provided inside the cooling chamber, a shell is installed on the outside of the spindle body, a liquid inlet is provided between the surface of the spindle body and the cooling chamber, a filter assembly is installed inside the liquid inlet, a fixing frame is installed inside the filter assembly, and a cleaning assembly is installed on the fixing frame.
[0006] The cleaning assembly includes a fan, a connecting rod, and a cleaning brush. The fan is rotatably mounted at equal intervals on the bottom of the fixed frame. A connecting rod is installed on the bottom of the fan, and a cleaning brush is installed on one end of the connecting rod.
[0007] Preferably, the filter assembly includes a mounting housing and a filter plate. The mounting housing is installed inside the liquid inlet via a threaded structure, and the filter plate is installed inside the mounting housing.

[0010] Preferably, the cross-section of the buffer plate is arc-shaped, and multiple sets of buffer plates form an "S"-shaped flow channel in the inner cavity of the cooling chamber.
[0011] Preferably, the bottom of the spindle body is provided with an outlet at a corresponding position below the inlet, and the outlet is fitted with a threaded cap via a threaded structure.
[0012] Preferably, two sets of connecting rods are symmetrically fixedly installed at the bottom of the wind turbine, and a cleaning brush is fixedly installed at the bottom of the connecting rod.
[0013] Compared with the prior art, this utility model has a cleaning component installed on the fixed frame. When the impeller rotates on the surface of the fixed frame under the impact, the surface of the filter plate can be cleaned by the cleaning brush during the rotation, preventing impurities inside the coolant from blocking the mesh of the filter plate.

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] This application provides a self-cleaning water-cooled electric spindle, including a spindle body 1; a cooling chamber 5 is provided on the inner side of the spindle body 1, a cooling assembly 6 is provided inside the cooling chamber 5, a housing 2 is installed on the outside of the spindle body 1, a liquid inlet 3 is provided between the surface of the spindle body 1 and the cooling chamber 5, a filter assembly 7 is installed inside the liquid inlet 3, a fixing frame 8 is installed inside the filter assembly 7, and a cleaning assembly 9 is installed on the fixing frame 8;
[0026] The cleaning assembly 9 includes a fan 901, a connecting rod 902, and a cleaning brush 903. The fan 901 is rotatably mounted at equal intervals on the bottom of the fixed frame 8. The connecting rod 902 is mounted on the bottom of the fan 901, and the cleaning brush 903 is mounted on one end of the connecting rod 902. The filter assembly 7 includes a mounting housing 701 and a filter plate 702. The mounting housing 701 is installed inside the liquid inlet 3 via a threaded structure. The filter plate 702 is installed inside the mounting housing 701. The fixed frame 8 is fixedly installed inside the mounting housing 701. 03 is in contact with the surface of the filter plate 702. The cooling assembly 6 includes a heat-conducting plate 601 and a buffer plate 602. The heat-conducting plate 601 is installed on the inner wall of the cooling chamber 5. Multiple sets of buffer plates 602 are staggered on the inner walls of the cooling chamber 5 and the heat-conducting plate 601. The cross-section of the buffer plate 602 is arc-shaped. Multiple sets of buffer plates 602 form an "S"-shaped flow channel in the inner cavity of the cooling chamber 5. Two sets of connecting rods 902 are symmetrically fixedly installed at the bottom of the impeller 901. A cleaning brush 903 is fixedly installed at the bottom of the connecting rod 902.
[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during use, the mounting housing 701 is installed into the inlet 3 via a threaded structure. Impurities in the coolant are filtered by the filter plate 702. After the coolant enters the cooling chamber 5, the flow rate is buffered by the "S"-shaped flow channels formed by multiple buffer plates 602 within the chamber. The heat-conducting plate 601 directs the heat of the coolant to the outside of the spindle body 1, cooling it and further improving the cooling effect. When the coolant enters the cooling chamber 5 through the mounting housing 701, it cools the impeller 901. Impact: When the impeller 901 rotates on the surface of the fixed frame 8 under the impact effect, the surface of the filter plate 702 can be cleaned by the cleaning brush 903 during the rotation process, so as to prevent impurities inside the coolant from blocking the mesh of the filter plate 702. This ensures that the coolant can smoothly enter the cooling chamber 5 to cool the main shaft body 1. Through the combined use of the filter assembly 7 and the cleaning assembly 9, not only can the impurities inside the coolant be cleaned, but the filter plate 702 can also be cleaned quickly, thereby further improving the cooling effect and working efficiency of the device for cooling the main shaft body 1.
[0028] Furthermore, a liquid outlet 4 is provided at the bottom of the main shaft body 1 at the corresponding position below the liquid inlet 3, and a threaded cover 401 is installed on the liquid outlet 4 through a threaded structure.
[0029] Specifically, such as Figure 1, Figure 2 As shown, during the use of the device, the coolant flows in the inner cavity of the cooling chamber 5, separating the threaded cap 401 from the outlet 4. The coolant inside the cooling chamber 5 is extracted by the external circulation component, and the coolant is cooled by heat exchange using the external cooling device. The external circulation cooling component then inputs the cooled coolant back into the inner cavity of the cooling chamber 5 through the inlet 3. The coolant cools the spindle body 1, preventing the spindle body 1 from overheating during use and affecting the normal operation of the device.
[0030] Working principle: The mounting shell 701 is installed into the inlet 3 via a threaded structure. Impurities inside the coolant are filtered by the filter plate 702. When the coolant enters the cooling chamber 5, the flow rate of the coolant is buffered by the "S"-shaped flow channel formed by multiple buffer plates 602 in the inner cavity of the cooling chamber 5. The heat of the coolant is transferred to the outside of the spindle body 1 by the heat conduction plate 601 to cool the spindle body 1, thereby further improving the cooling effect of the coolant on the spindle body 1. When the coolant enters the cooling chamber 5 through the mounting shell 701, the coolant impacts the impeller 901. Under the impact, the impeller 901 rotates on the surface of the fixing frame 8. During the rotation, the surface of the filter plate 702 is cleaned by the cleaning brush 903 to prevent impurities inside the coolant from blocking the mesh of the filter plate 702, thus ensuring that the coolant can smoothly enter the cooling chamber 5 to cool the spindle body 1.
[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
