DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings of the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0026] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings.

[0027] In combination Figures 1-6 A kind of component numerical control lathe cooling device, including lathe 1, lathe 1 is by shell 11, bed 12 and hatch 13, shell 11 is detachably connected on bed 12 by bolt, this detachable connection mode is convenient for the maintenance and maintenance to the inside of bed 12, improves the maintainability of equipment.Bed 12 is slidably connected with slide plate 2 and tailstock 3 by motor and screw rod, can flexibly adjust processing position, to adapt to the processing needs of different sizes and shapes components, improves the versatility and machining precision of lathe.Hatch 13 is slidably connected on shell 11 and bed 12, both facilitate operator to observe processing process, and can prevent cooling liquid and chip from splashing out, guarantee the safety and neatness of operating environment.Slide plate 2 is slidably connected with tool rest seat 4, tool rest seat 4 can be moved and replaced tool according to machining process, satisfy the processing requirement of diversification.Bed 12 is provided with collecting groove 120, two liquid collecting tanks 6 are clamped on the inner wall of collecting groove 120, collecting groove 120 is used to collect used cooling liquid, liquid collecting tank 6 carries out preliminary collection and sedimentation to cooling liquid, it is convenient for subsequent processing and recycling to cooling liquid, reduces the use cost of cooling liquid.The bottom end side of tool rest seat 4 is fixedly provided with cooling liquid circulating mechanism 5.

[0028] The cooling liquid circulating mechanism 5 comprises a spray pipe 51, a conveying pump 52, a storage tank 53, a refrigeration coil 54, and a refrigeration machine 55. The spray pipe 51 and the conveying pump 52 are fixedly installed at the end of the slide plate 2 on one side of the tool holder seat 4. One end of the conveying pump 52 is fixedly connected with the spray pipe 51 through a pipeline, and the other end is fixedly connected with the storage tank 53 through a pipeline. The conveying pump 52 conveys the cooling liquid in the storage tank 53 to the spray pipe 51, and the spray pipe 51 accurately sprays the cooling liquid to the machining area, effectively reducing the heat generated during cutting of the tool and the workpiece, reducing tool wear, and improving machining quality and efficiency. The storage tank 53 is fixedly installed on one side of the bottom of the slide plate 2. A spiral refrigeration coil 54 is fixedly arranged in the storage tank 53. A refrigeration machine 55 is fixedly installed on the outer wall of one side of the storage tank 53. The refrigeration coil 54 is in communication with the refrigeration machine 55 through a copper pipe extending out of the storage tank 53. The spiral refrigeration coil 54 greatly increases the contact area with the cooling liquid, so that the refrigeration machine 55 can more efficiently cool the cooling liquid, ensuring that the cooling liquid always maintains a relatively low temperature, thereby enhancing the cooling effect and stability of the cooling device. The storage tank 53 is fixedly provided with a connection end 531, which is convenient for connecting with other components to realize the circulation of the cooling liquid and ensure the normal operation of the entire cooling device. The end of the connection end 531 extending into the storage tank 53 is fixedly provided with a three-stage filter screen 63. The three-stage filter screen 63 performs the last filtration on the returned cooling liquid, further removes residual impurities, ensures that the cooling liquid entering the storage tank 53 has higher cleanliness, and improves the cooling effect and equipment operation stability. The storage tank 53 is fixedly and communicatively provided with a liquid inlet pipe 532 for supplementing the cooling liquid. The liquid inlet pipe 532 facilitates timely supplement of the cooling liquid, ensures the normal operation of the cooling liquid circulating mechanism 5, and maintains the continuous working capacity of the cooling device.

[0029] The tool holder seat 4 and the tailstock 3 are each fixedly provided with a temperature sensor 9, which is electrically connected with the refrigeration machine 55 through a line. This design can monitor the temperature of the tool holder seat 4 and the tailstock 3 in real time. When the temperature is too high, the temperature sensor 9 transmits a signal to the refrigeration machine 55, so that the refrigeration machine 55 starts to cool the cooling liquid in time, ensures that the key parts of the lathe are in an appropriate temperature range, and avoids affecting the machining precision and equipment life due to excessively high temperature.

[0030] The bottom of the liquid collecting tank 6 is conical. This structure is conducive to the concentration of impurities in the cooling liquid to the bottom, facilitating subsequent filtration and separation operations, and improving the recovery and reuse efficiency of the cooling liquid. The two liquid collecting tanks 6 are clamped with a first filter screen 61 arranged obliquely, and the bottom end of the liquid collecting tank 6 is fixedly connected with a square tube 64. The connection between the square tube 64 and the liquid collecting tank 6 is inserted with a second filter strip 62, and the other end of the square tube 62 is fixedly connected with a centrifugal separator 7. The first filter screen 61 and the second filter strip 62 preliminarily filter the cooling liquid to intercept larger impurities, and the centrifugal separator 7 further separates the fine impurities by using centrifugal force. The multi-stage filtration and separation mode effectively purifies the cooling liquid, reduces the damage of impurities to the tool and the workpiece, and prolongs the service life of the equipment. The centrifugal separator 7 is fixedly installed at the middle of the bottom end of the bed body 12, and one end of the centrifugal separator 7 is fixedly connected with a flexible hose 71. The flexible hose 71 is fixedly connected with the storage tank 53 through a connecting head. One end of the centrifugal separator 7 is fixedly connected with a slag discharge pipe 72, and the outer shell 11 below the slag discharge pipe 72 is slidably provided with a slag collecting frame 8. The impurities separated by the centrifugal separator 7 fall into the slag collecting frame 8 through the slag discharge pipe 72, which is convenient for cleaning. The purified cooling liquid flows back to the storage tank 53 through the flexible hose 71, ensuring the circulation use of the cooling liquid and reducing the production cost.

[0031] Working principle: When the lathe 1 is running, the temperature sensors 9 on the tool holder seat 4 and the tailstock 3 monitor the temperature in real time. When the temperature is higher than the set value, a signal is transmitted to the refrigerator 55. The delivery pump 52 extracts the cooling liquid from the storage tank 53, and sprays it towards the machining area through the spray pipe 51 to cool it down. The used cooling liquid flows into the collecting groove 120 of the bed body 12, enters the liquid collecting tank 6, is filtered by the first filter screen 61, and then is further filtered by the second filter strip 62 through the square tube 64, and then flows into the centrifugal separator 7. The centrifugal separator 7 separates the impurities by using centrifugal force. The impurities fall into the slag collecting frame 8 through the slag discharge pipe 72, and the cooling liquid is purified by the third filter screen 63 at the connecting head 531 and then flows back to the storage tank 53 through the flexible hose 71. The spiral refrigeration coil 54 in the storage tank 53 is cooled by the refrigerator 55 to realize the circulation cooling.
