Description

Technical Field

[0001] This utility model belongs to the field of cooling technology for turning processes, and specifically relates to a cooling structure for turning motor rotors. Background Technology

[0002] The motor rotor is the rotating part of the motor. The motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy. Currently, when the motor rotor is being machined, a special cooling structure for turning motor rotors is usually used.

[0003] Existing cooling structures for turning motor rotors typically use a liquid pump to spray coolant through pipes to the machining area, and then a filter screen to filter the coolant containing impurities. Although this can achieve a certain filtration effect, there are still some problems in actual operation. In particular, after long-term use, the filter screen becomes clogged with impurities, which leads to a decrease in the filtration and circulation efficiency of the coolant, and the cooling effect cannot be maintained stably, thus affecting the smooth progress of the entire machining process. Utility Model Content

[0004] In view of this, the present invention provides a cooling structure for turning motor rotors, which can achieve efficient filtration and circulation of coolant through a filter assembly. This avoids the problem of filter screen clogging caused by impurity accumulation, and maintains stable cooling efficiency through the synergistic effect of semi-circular filtration and rotary scraping, ensuring continuous and efficient heat dissipation during the machining process.

[0005] To solve the above-mentioned technical problems, this utility model provides a cooling structure for turning motor rotors, including a turning machine and a cooling mechanism disposed therein. The turning machine is equipped with a filter assembly, which includes a fixed tube disposed within the turning machine. A filter screen is disposed inside the fixed tube, and a collection element is placed at the edge of the filter screen. The filter screen is semi-circular, which realizes efficient filtration and circulation of coolant, avoids the problem of filter screen clogging caused by impurity accumulation, and maintains stable cooling efficiency through semi-circular filtration, ensuring continuous and efficient heat dissipation during the machining process.

[0006] The collection device includes a collection box placed at the upper edge of the filter screen. The collection box has a ring structure, which means that impurities are collected in a concentrated manner.

[0007] The filter assembly also includes a rotating rod rotatably connected to the middle of the filter screen. The upper end of the rotating rod is equipped with a scraper, which slides in contact with the filter surface of the filter screen to further improve the cleaning effect of the filter screen.

[0008] The filter assembly also includes a guide plate located at the top of the collection box. The guide plate fits into the upper opening of the fixed tube, thus guiding the liquid carrying cutting impurities through the guide plate.

[0009] The lathe has a drip box located below the fixed tube in the inner cavity of the machine tool. The drip box has evenly distributed drip holes and a rotating hole that matches the rotating rod, which ensures that the coolant can be completely cooled.

[0010] The lower end of the drip box is equipped with a motor, and the output shaft of the motor is fixedly connected to the lower end of the rotating rod, thus providing a driving source for the rotating rod.

[0011] The cooling mechanism includes a liquid pump located at the bottom of the inner cavity of the turning machine. The liquid pump has a cooling pipe at its supply end, and the liquid outlet of the cooling pipe penetrates the outer surface of the turning machine and extends to the outside. The liquid outlet of the cooling pipe corresponds to the turning part of the motor rotor, thus achieving cooling and temperature reduction of the turning part of the motor rotor.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. The cooled liquid, carrying impurities generated during cutting, flows into the fixed pipe and is then filtered through a semi-circular filter screen. The semi-circular structure allows the impurities to slide naturally to the edge and fall into the annular collection box, achieving efficient filtration and circulation of the coolant. This avoids the problem of filter screen clogging caused by impurity accumulation, and the synergistic effect of semi-circular filtration and rotary scraping maintains stable cooling efficiency, ensuring continuous and efficient heat dissipation during the processing.

[0014] 2. The motor drives the rotating rod and scraper to rotate synchronously. The scraper rotates along the filter screen surface to continuously remove impurities attached to the filter screen and prevent clogging. The scraped-off impurities are further collected by the collection box, which can further improve the cleaning effect of the filter screen and ensure its filtration efficiency.

[0015] 3. Simply remove the collection box periodically to process the collected impurities. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a cooling structure for machining motor rotors, such as... Figure 1-4 As shown: including a turning machine 100 and a cooling mechanism disposed therein, the turning machine 100 is provided with a filter assembly, the filter assembly includes a fixed tube 400 disposed therein, the fixed tube 400 is provided with a filter screen 401, a collection element is placed at the edge of the filter screen 401, the filter screen 401 is in the shape of an inverted semi-circle, and the collection element includes a collection box 402 placed at the upper end of the edge of the filter screen 401, the collection box 402 is in the shape of a ring.

[0023] During the turning of the motor rotor, the cooling mechanism sprays coolant onto the turning area of ​​the motor rotor for cooling. The cooled liquid, carrying impurities generated during cutting, flows into the fixed pipe 400 and is then filtered through the semi-circular filter screen 401. Utilizing the semi-circular structure, the impurities naturally slide to the edge and fall into the annular collection box 402, achieving efficient filtration and circulation of the coolant. This avoids the problem of filter screen clogging caused by impurity accumulation and maintains stable cooling efficiency through semi-circular filtration, ensuring continuous and efficient heat dissipation during the machining process. Then, the collected impurities can be processed by periodically removing the collection box 402.

[0024] like Figure 1-4 As shown, the filter assembly also includes a rotating rod 403 rotatably connected to the middle of the filter screen 401. The upper end of the rotating rod 403 is provided with a scraper 404, which has an arc-shaped design and slides in contact with the filter surface of the filter screen 401.

[0025] The rotating rod 403 and scraper 404 rotate synchronously. The scraper 404 rotates along the filter surface of the filter screen 401, continuously removing impurities attached to the filter screen to prevent clogging. The scraped-off impurities are further received by the collection box 402, which can further improve the cleaning effect of the filter screen 401 and ensure its filtration efficiency.

[0026] like Figure 1-4As shown, the filter assembly also includes a guide plate 405 disposed on the upper end of the collection box 402. The guide plate 405 fits into the upper opening of the fixed tube 400. The guide plate 405 is ring-shaped, and the circular opening in the middle corresponds to and matches the upper end of the filter screen 401.

[0027] The liquid, carrying impurities generated during cutting, flows into the fixed pipe 400 through the guide plate 405.

[0028] like Figure 1-4 As shown, a drip box 500 is provided in the inner cavity of the turning machine 100 below the fixed tube 400. The drip box 500 has evenly distributed drip holes and a rotating hole that is compatible with the rotating rod 403.

[0029] This allows the filtered coolant to drip evenly, ensuring that the coolant is completely cooled.

[0030] like Figure 1-4 As shown, a motor 600 is provided at the lower end of the drip box 500, and the output shaft of the motor 600 is fixedly connected to the lower end of the rotating rod 403.

[0031] The output shaft of motor 600 rotates, driving the rotating rod 403 and its auxiliary mechanisms to rotate synchronously, thereby providing a driving source for the rotating rod 403.

[0032] like Figure 1-3 As shown, the cooling mechanism includes a liquid pump 200 located at the bottom of the inner cavity of the turning machine 100. The liquid supply end of the liquid pump 200 is provided with a cooling pipe 300. The liquid outlet end of the cooling pipe 300 penetrates the outer surface of the turning machine 100 and extends to the outside. The liquid outlet end of the cooling pipe 300 corresponds to the turning part of the motor rotor.

[0033] When machining the motor rotor, start the liquid pump 200. The liquid pump 200 operates to deliver coolant into the cooling pipe 300, and sprays it from its outlet to the machining area of ​​the motor rotor for cooling.

[0034] The working principle of the cooling structure for turning motor rotors provided by this utility model is as follows: During the turning of the motor rotor, the liquid pump 200 is started, and the liquid pump 200 operates to deliver coolant to the cooling pipe 300. The coolant is sprayed from its outlet end to the turning area of ​​the motor rotor for cooling. The cooled liquid carries the impurities generated during cutting through the guide plate 405 and flows into the fixed pipe 400. Then it is filtered by the semi-circular filter screen 401. The semi-circular structure allows the impurities to slide naturally to the edge and fall into the annular collection box 402. At the same time, the motor 600 is started periodically. The output shaft of the motor 600 rotates, driving the rotating rod 403 and the scraper. The plate 404 rotates synchronously, and the scraper 404 rotates along the filter surface of the filter screen 401 to continuously remove impurities attached to the filter screen and prevent clogging. The scraped impurities are further collected by the collection box 402, while the filtered coolant flows back to the system for recycling evenly through the drip holes of the drip box 500 below. The whole process achieves efficient filtration and circulation of coolant, which not only avoids the problem of filter screen clogging caused by impurity accumulation, but also maintains stable cooling efficiency through the synergistic effect of semi-circular filtration and rotating scraping, ensuring continuous and efficient heat dissipation during the processing. Then, the collected impurities can be processed by periodically removing the collection box 402 through the guide plate 405.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
