Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0024] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0025] In actual production, traditional large vertical lathes, such as 5-meter and 6.3-meter lathes, are not designed or used with coolant circulation and spray systems. This is mainly due to several reasons: 1. Design considerations: Traditional large vertical lathes are primarily designed for machining large or heavy workpieces with large diameters and short lengths, as well as complex-shaped parts that are difficult to clamp on horizontal lathes. Therefore, designers generally consider the use of coolant unnecessary. 2. Maintenance issues: The large worktable of large vertical lathes makes the maintenance and cleaning of coolant circulation and spray systems difficult, and may also lead to serious malfunctions such as jamming and corrosion of rotating parts. 3. Equipment characteristics: Large vertical lathes have spacious machining areas and generally have sufficient heat dissipation capacity, thus eliminating the need for additional coolant. Therefore, without increasing material, installation, and maintenance costs, the operating temperature of the equipment remains within an acceptable range, making the use of coolant unnecessary. In summary, the vast majority of large vertical lathes used in actual production are not equipped with dedicated cutting fluid cooling and lubrication systems.

[0026] However, due to their excellent physical and chemical properties, titanium and titanium alloys are widely used in aerospace, medical devices, and precision instruments. This also presents new challenges to modern machining and cutting technologies: the machining and cutting of titanium alloys is more difficult, mainly due to their physical and chemical properties. 1. Low thermal conductivity: Titanium alloys have extremely low thermal conductivity, causing heat generated during cutting to be difficult to dissipate and instead concentrated in the cutting area. 2. Increased tool tip temperature: The tool tip temperature can rise instantly to 1000℃, leading to rapid tool wear, cracking, and breakage. 3. Damage to surface integrity: High temperatures can also damage the surface integrity of titanium alloy parts, reducing their geometric accuracy. Therefore, when machining titanium and titanium alloys using large vertical lathes, it is necessary to consider adding a heat dissipation system to improve the heat dissipation capacity of the large vertical lathe.

[0027] Please see Figure 1 This utility model proposes a spray cooling system for a large vertical lathe, the structure of which includes: a guide ring 3, which is embedded around the turning table 1 and has a drain outlet at the bottom; a spray device, which is located near the tool holder of the vertical lathe; and a filter circulation device 5, which is located in a water storage tank 4 near the guide ring 3 and is connected to the spray device.

[0028] Specifically, during operation, the tool post on the vertical lathe 2 is suspended above the turning table 1, and turning is achieved by the rotation of the turning table 1. To cool the cutting tool, this invention includes spray nozzles near the tool post for targeted cooling. Coolant (pure water) falls onto the surface of the turning platform 1, then flows into the guide ring 3 for collection, and finally into the water storage tank 4. By setting the guide ring 3, coolant flow to the back of the turning platform 1 is prevented, thus effectively preventing corrosion. Furthermore, the guide ring 3 also has the ability to collect turning debris, preventing the turning platform 1 from jamming during rotation.

[0029] In one embodiment, see Figure 2 The guide ring 3 includes: a horizontal extension 31, which is fitted between the bottom of the turning table 1 and the station plate, and does not contact the bottom of the turning table 1; and a U-shaped groove 32, which is connected to the side of the horizontal extension 31.

[0030] For details, please see Figure 3 The horizontal extension 31 is slightly tilted upward to catch water and prevent coolant from flowing to the back of the turning table 1 and dripping into the shaft well.

[0031] In one embodiment, the bottom surface of the U-shaped channel 31 is also provided with multiple collection channels, which evenly divide the U-shaped channel into multiple segments, and the drain outlet is located at the bottom of one or more collection channels.

[0032] Specifically, the collection trough is used to block the flow of debris at the bottom of the U-shaped trough 31, preventing the debris from quickly clogging the drain outlet of the guide ring 3 and extending the debris cleaning cycle.

[0033] In one embodiment, the spraying device includes: a telescopic bracket and a spray head; wherein one end of the telescopic bracket is detachably fixedly connected to the vertical lathe tool post, and the other end is detachably connected to the spray head.

[0034] In one embodiment, the shower head has a multi-outlet layout for controlling the spray range. Specifically, a shower head can be used instead of a shower head.

[0035] In one embodiment, the spraying device further includes a control valve connected between the filter circulation device 5 and the spray head, for controlling the water flow rate.

[0036] In one embodiment, the filtration and circulation device 5 includes a water pump or a paper tape filter. Specifically, the paper tape filter has an additional filtration system compared to the water pump, which can prevent impurities in the spray water from affecting the turning process. In an optional embodiment, the water pump can be positioned at a certain height above the bottom of the water storage tank to avoid drawing in too many impurities.

[0037] In one embodiment, see Figure 4 The paper tape filter 5 includes: a housing 51, a paper tape box 52 disposed on the top of the housing, a paper feed controller 53 disposed inside the paper tape box 52, and a water pump 54 disposed on the top of the housing; wherein, the top of the housing is provided with a water inlet 55, which is connected to the drain outlet of the guide ring 3 through a hose, and a filter box 56 is provided below the water inlet 55. The paper feed controller 53 is used to feed the filter paper in the paper tape box 52 into the filter box 56 to achieve filtration and automatically replace the filter paper. The bottom front of the housing 51 is provided with a water outlet 57, which is connected to the water inlet of the water pump 54 through a hose.

[0038] For details, please see Figure 5 During use, the water enters the paper tape filter 5 through the inlet 55 via the guide ring 3 and falls into the filter box 56 below. After being filtered by the filter paper, it flows into the bottom of the housing 51, and is then pumped by the water inlet 57 and the water pump 54 into the spray head of the spray device for spraying, thus achieving recycling. The housing 51 of the paper tape filter 5 helps to reduce the evaporation of moisture, thereby ensuring the dryness of the working environment and preventing the turning table 1 from rusting.

[0039] In one embodiment, the paper tape filter further includes a waste paper box 58, disposed behind the filter box 56, for storing waste paper.

[0040] In one embodiment, the upper surface and sides of the turning table 1 are coated with a waterproof layer, which can be achieved by brushing on waterproof paint or laying a waterproof film.

[0041] Through the above embodiments, this utility model realizes a solution for adding a spray water cooling system to a large vertical lathe system, which can effectively achieve the collection, filtration and circulation of coolant.
