Description

Technical Field

[0001] This utility model belongs to the field of cooling technology for machining equipment, specifically a cooling device for an inverted CNC lathe structure. Background Technology

[0002] With the development of manufacturing equipment technology, more and more enterprises are using CNC lathes to machine rotating parts such as shafts and discs. CNC lathes can be broadly classified into two categories based on their structure: horizontal lathes and vertical lathes. A patent with publication number CN113319648B proposes a CNC lathe design for easy coolant recovery. By setting up a collection frame and a scraper frame, coolant and chips are separated, thereby improving coolant recovery efficiency. However, this design is mainly suitable for horizontally arranged lathe structures. In inverted CNC lathes, the natural falling direction of chips and coolant is restricted, which may make it difficult for coolant to flow smoothly into the collection device, thus affecting the recovery effect. Furthermore, this design does not adequately consider the optimization of the coolant spray angle in inverted lathes, which may make it difficult to achieve efficient cooling of the tool and workpiece. Utility Model Content

[0003] The purpose of this invention is to address the problems of low coolant recovery efficiency and insufficient optimization of cooling spray angle in existing inverted CNC lathes, and to provide a cooling device for inverted CNC lathe structures. This device improves the separation of coolant and chips by optimizing the coolant's flow path and spray direction, while simultaneously enhancing the cooling performance for both the cutting tool and the workpiece, thereby meeting the specific needs of inverted lathes.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cooling device for an inverted CNC lathe structure includes a coolant guiding assembly, a spray adjustment assembly, and a recovery assembly. The coolant guiding assembly is installed above the lathe's machining area and has four branch outlets at its lower end to evenly distribute the coolant throughout the machining area. The spray adjustment assembly is located below the coolant guiding assembly and includes four rotatable nozzles, each connected to a distributor via a ball joint to allow for flexible adjustment of the spray angle. The recovery assembly is located at the bottom of the lathe's machining area and includes an inclined guide plate and a collection trough below the guide plate. A separator filter in the guide plate separates the coolant and chips, guiding them to different recovery channels.

[0006] This invention utilizes a coolant guiding assembly to introduce coolant from the top of the lathe and distribute it evenly to the machining area through a splitter outlet, preventing the coolant from concentrating due to gravity. Simultaneously, the nozzles in the spray adjustment assembly are connected to the distributor via ball joints, allowing the nozzles to adjust their spray angle according to machining requirements, ensuring precise coolant coverage of the contact surfaces between the tool and the workpiece. Furthermore, the guide plates in the recovery assembly are arranged at an angle, utilizing the difference in chip weight and coolant flow to achieve natural separation, with each chip ultimately entering its corresponding recovery channel.

[0007] As a preferred embodiment of this invention, the coolant guiding assembly includes a main pipe and four branch pipes. The main pipe is arranged laterally along the top of the lathe, and its two ends are connected to an external coolant supply system via flanges. The branch pipes extend vertically downwards, and a distributor is provided in the middle of each branch pipe to evenly distribute the coolant to different locations in the machining area. This arrangement ensures that the coolant forms a uniform coverage effect within the lathe machining area, preventing localized overheating or insufficient cooling.

[0008] As a preferred embodiment of this invention, the nozzle in the injection adjustment assembly is connected to a guide hose, allowing for large-angle adjustment of the guide hose during processing, thereby enhancing the coverage and impact force of the coolant. Furthermore, the nozzle's ball joint connection structure is fixed by a threaded locking mechanism, allowing the operator to manually rotate the locking mechanism to adjust and fix the nozzle angle, ensuring the accuracy of the injection direction.

[0009] As a preferred embodiment of this utility model, the top of the ball joint connection structure is connected to the diverter via a telescopic hose to prevent water leakage when adjusting the angle, and the bottom of the ball joint connection structure is connected to the guide hose.

[0010] As a preferred embodiment of this invention, the surface of the guide plate in the recovery assembly is coated with a hydrophobic coating to reduce coolant residue on the guide plate and improve the coolant recovery rate. The tilt angle of the guide plate is between 15° and 30°, which ensures that the chips slide off smoothly while preventing coolant from splashing out due to excessive flow rate. A separator filter plate is provided at the end of the guide plate to guide the coolant and chips to different recovery channels, thereby achieving efficient separation of the two.

[0011] As a preferred embodiment of this invention, a filter screen is provided above the collection tank to further separate fine cutting particles remaining in the coolant. The filter screen is detachable for easy regular cleaning and maintenance. A liquid level sensor is also provided on one side of the collection tank. When the coolant level reaches a preset value, the sensor will trigger a signal to start an external pump to transport the coolant back to the coolant supply system, thereby realizing the recycling of the coolant.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] This invention solves the problem of coolant flow into the machining area due to gravity in inverted lathes by designing a coolant guiding component that introduces coolant from the top of the lathe and distributes it evenly to the machining area.

[0014] The nozzles in the spray adjustment assembly are connected by a ball joint to allow for flexible adjustment of the spray angle, ensuring that the coolant can accurately cover the contact surface between the tool and the workpiece, thereby improving the cooling effect.

[0015] The guide vanes in the recovery assembly are arranged at an angle, and combined with the design of a hydrophobic coating and a separator filter plate, they achieve efficient separation of coolant and chips, thereby improving the coolant recovery rate.

[0016] Furthermore, the filter screen and liquid level sensor in the collection tank further optimize the recycling efficiency of the coolant. Through the above technical means, this utility model effectively solves the problems of low coolant recovery efficiency and insufficient spray angle optimization in inverted CNC lathes, and has significant practicality and innovation.

Figure 1 To be continued Figure 4 Please provide a detailed explanation. For example... Figure 1 As shown, the cooling device includes a coolant guiding assembly 1, a spray regulating assembly 2, and a recovery assembly 3. These components work together in the lathe machining area to achieve efficient distribution, precise spraying, and effective recovery of the coolant.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal connection of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] The specific structure of each component and its connection relationship are described below in the order of the reference numerals in the attached drawings. Example 1

[0028] The coolant flow guiding assembly 1 is one of the core components of the entire device, mainly composed of a main pipe 4, branch pipes 5, and a distributor 6; for example... Figure 2As shown, the main pipe 4 is arranged laterally along the top of the lathe, and both ends are connected to the external coolant supply system through flanges. This connection method ensures that coolant can be stably input from the external system into the device.

[0029] It should be noted that the branch pipe 5 extends vertically downward and connects to the main pipe 4. Each branch pipe 5 is equipped with a distributor 6 at its end, and the opening of the distributor 6 faces the processing area. The design of the distributor 6 allows the coolant to be evenly dispersed before entering the processing area, avoiding the phenomenon of concentrated flow of coolant due to gravity.

[0030] The number of branch pipes 5 is set reasonably according to the size of the lathe machining area, usually 4 to 8, to ensure that the coolant can cover the entire machining area; in addition, the main pipe 4 and the branch pipes 5 are fixed by welding to ensure the stability of the overall structure.

[0031] The top of the ball joint connection structure 8 is connected to the diverter 6 via a telescopic hose to prevent water leakage when adjusting the angle, and the bottom of the ball joint connection structure 8 is connected to the guide hose 9. Example 2

[0032] The injection regulating assembly 2 is located below the coolant guiding assembly 1. Its core component is a plurality of nozzles 7, which are connected to the lower part of the guiding hose 9. The end of the guiding hose 9 away from the nozzles 7 is connected to the distributor via a ball joint connection structure 8; for example Figure 3 As shown, the nozzle 7 is connected to the flow guide hose 9.

[0033] It should be noted that this design allows the coolant to be adjusted at a large angle when passing through the guide hose 9, thereby expanding the coverage of the coolant and enhancing the impact force; the ball joint connection structure 8 is fixed by a threaded locking mechanism, the ball joint connection structure 8 rotates on the support housing 17 and the support housing 17 is connected to the bottom of the distributor 6, and the ball joint connection structure 8 is fixed by bolts passing through the support housing 17.

[0034] Therefore, the operator can manually rotate the locking mechanism to adjust the angle of the nozzle 7 and fix it in the required position to meet the coolant spray angle requirements under different processing needs.

[0035] The number of nozzles 7 corresponds to the number of branch pipes 5. Each nozzle 7 is located directly below the corresponding branch pipe 5 to ensure that the coolant can be evenly distributed from the distributor 6 and directly enter the nozzle 7, thereby achieving precise spraying. Example 3

[0036] The recycling component 3 is located at the bottom of the lathe machining area, and it mainly consists of a guide plate 10, a separator filter plate 11, and a collection tank 12; for example... Figure 4As shown, the guide plate 10 is inclined at an angle between 15° and 30°. This angle range ensures that the chips slide off smoothly and prevents the coolant from splashing out due to excessive flow rate.

[0037] In this embodiment, the surface of the guide plate 10 is coated with a hydrophobic coating, which reduces the coolant residue on the guide plate 10 and improves the coolant recovery rate; wherein the end of the guide plate 10 is provided with a separator filter plate 11, which guides the coolant and chips to different recovery channels respectively.

[0038] The collection tank 12 is located at the end of the guide plate 10, and a filter screen 13 is provided above the collection tank to further separate the fine cutting particles remaining in the coolant.

[0039] Based on the above embodiments, the filter screen 13 adopts a detachable design, which is convenient for regular cleaning and maintenance; a liquid level sensor 14 is also provided on one side of the collection tank 12. When the coolant level reaches the preset value, the liquid level sensor 14 will trigger a signal to start the external pump 15 to transport the coolant back to the coolant supply system through the recycling pipe 16, thereby realizing the recycling of coolant.

[0040] This configuration ensures the efficient operation of the entire device by regulating the connections and collaboration between the components, thus meeting the specific requirements of the inverted CNC lathe.

[0041] Through the above-described operation process, this utility model effectively solves the problem that coolant in inverted CNC lathes is difficult to flow smoothly into the machining area due to the limited natural falling direction, while optimizing the coolant spray angle and improving the cooling effect.

[0042] Therefore, the efficient separation design of coolant and chips, as well as the recycling mechanism, significantly improve the recovery and utilization rate of coolant, meeting the special requirements of inverted CNC lathes.

[0043] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
