Description

Technical Field

[0001] This utility model relates to the field of machining cooling technology, specifically to a CNC machine tool cutting fluid spraying mechanism. Background Technology

[0002] In CNC machine tool machining, the cutting fluid spraying mechanism is an important auxiliary component. It can accurately deliver cutting fluid to the cutting area between the tool and the workpiece, and the cooling effect of the cutting fluid can remove the heat generated during machining, preventing the tool from being damaged by high temperature. At the same time, the cutting fluid can form a lubricating film between the tool and the workpiece, reducing friction, and can also wash away the debris generated during the cutting process, providing a guarantee for stable machining. It is one of the key supports for CNC machine tools to achieve efficient operation.

[0003] Utility model patent CN221849529U discloses a cutting fluid spraying structure for a position-adjustable CNC multi-axis multi-station machining center. This structure includes a cutting fluid sprayer comprising a bellows, a connecting block, and a mounting head. The mounting head is integrally formed on one side of the connecting block, and the bellows are positioned at both ends of the connecting block, with the two bellows symmetrically arranged. By designing a uniform spraying mechanism, when the cutting fluid sprayer is fixedly installed and sprays cutting fluid at the operating position of the CNC multi-axis multi-station machining center, the end of the spray head is aligned with the cutting edge after the connecting ring is reinforced. The cutting fluid enters through the bellows and inlet into the connecting channel. When the cutting fluid enters the connecting channel, it is sprayed onto the edge of the machining position by the spray head, facilitating uniform cutting fluid spraying and improving the uniform spraying effect of the cutting fluid sprayer on the machining area of ​​the CNC multi-axis multi-station machining center.

[0004] The cutting fluid spraying structure of this adjustable CNC multi-axis multi-station machining center only focuses on spraying position adjustment and installation fixation, without setting up cutting fluid filtration-related structures. This causes impurities that may be contained in the coolant to be sprayed directly through the spraying components, which can easily cause the spraying channels to become blocked. They may also adhere to the workpiece machining surface or the cutting tool, affecting machining accuracy and tool life. In view of this, we propose a cutting fluid spraying mechanism for CNC machine tools. Utility Model Content

[0005] The purpose of this invention is to provide a cutting fluid spraying mechanism for CNC machine tools to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A CNC machine tool cutting fluid spraying mechanism includes a magnetic base, the top of which is equipped with a filter assembly for filtering cutting fluid. The input end of the filter assembly is connected to an external cutting fluid source through an inlet pipe, and the output end of the filter assembly is connected to a universal bamboo tube.

[0008] The filter assembly includes a stand and a cover mounted radially on the stand. A groove is formed on the side of the stand, and a hollow cylindrical protrusion is provided on the side wall of the groove. The cover is fitted into the protrusion and threadedly connected to it. A horizontally recessed slot is formed on the side wall of the groove inside the protrusion. An inlet channel and a transverse channel, both communicating with the side wall of the groove, are formed on the outer surface of the stand. The inner ends of both the inlet channel and the transverse channel extend into the protrusion and are symmetrically distributed vertically around the slot, with the inlet channel located at the bottom. An inlet pipe communicates with the inlet channel. An outlet channel, communicating with the transverse channel, is formed at the top of the stand, and a universal bamboo-joint tube communicates with the outlet channel. A frame is rotatably connected inside the cover, and a filter screen is provided inside the frame. An insert plate is provided on the end of the frame near the stand, and the insert plate is inserted into the slot.

[0009] Preferably, the bottom end of the stand is integrally formed with a base plate, which is fixed to the top of the magnetic base by bolts; the outer end of the liquid inlet channel is threadedly connected to a first pipe joint, and the end of the liquid inlet pipe is sleeved and installed on the outer end of the first pipe joint.

[0010] Preferably, a plug is embedded at the outer end of the transverse channel; a second pipe joint is threaded to the top of the liquid outlet channel, and the liquid inlet end of the universal bamboo tube is sleeved and installed on the outer end of the second pipe joint.

[0011] In these two settings, the base plate enhances the stability of the stand installation, and the first pipe joint improves the sealing of the connection between the liquid inlet pipe and the liquid inlet channel to prevent cutting fluid leakage.

[0012] Preferably, a plug is embedded at the outer end of the transverse channel; a second pipe joint is threaded to the top of the liquid outlet channel, and the liquid inlet end of the universal bamboo tube is sleeved and installed on the outer end of the second pipe joint.

[0013] In these two settings, the plug seals the outer end of the transverse channel to prevent leakage, and the second pipe joint enhances the sealing of the connection between the universal bamboo joint pipe and the liquid outlet channel.

[0014] Preferably, the top and bottom edges of the slot are provided with guide bevels, which are used to guide the insertion of the insert plate.

[0015] In this setting, the guide bevel guides the insert plate to quickly align and insert into the slot, reducing assembly time.

[0016] Preferably, the cover is a transparent cylindrical structure, with the first end of the cover being open and the last end being closed; the outer circumferential surface of the first end of the cover is provided with external threads, and the inner wall of the convex sleeve is provided with internal threads, with the thread parameters of the external threads and the internal threads being compatible.

[0017] In this design, the transparent structure facilitates observation of impurities on the filter screen, the open end allows for easy assembly and disassembly of the sleeve, and the threaded fit ensures a stable and sealed connection between the cover and the sleeve.

[0018] Preferably, the sleeve frame is a flat plastic structure, and the outer surface of the sleeve frame is tightly fitted to the inner wall of the cover cylinder; the end of the sleeve frame is provided with a convex shaft, which passes through the end of the cover cylinder and is fixed with a fixing ring, and the sleeve frame can rotate circumferentially around the convex shaft inside the cover cylinder.

[0019] In this configuration, a tight fit prevents leakage of unfiltered cutting fluid, and the convex shaft and retaining ring ensure stable rotation of the sleeve without detachment, facilitating filter cleaning and replacement.

[0020] Preferably, the insert plate protrudes from the front end of the cover cylinder, and its protrusion distance is greater than the depth of the sleeve, so as to ensure that when installing the cover cylinder, the insert plate can be inserted into the slot before the cover cylinder and the sleeve are threaded together.

[0021] In this setting, inserting the insert plate first can pre-position the cover, improving the accuracy of cover installation.

[0022] Preferably, the flow path of the cutting fluid in this mechanism is as follows: external cutting fluid source → inlet pipe → inlet channel → lower half of the cover cylinder horizontally separated by the frame → filter screen inside the frame → upper half of the cover cylinder horizontally separated by the frame → transverse channel → outlet channel → universal bamboo joint pipe.

[0023] In this setting, the path ensures that the cutting fluid is filtered throughout the entire process, flows smoothly without stagnation, and guarantees the cleanliness of the sprayed cutting fluid.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The cutting fluid spraying mechanism of this CNC machine tool, through the setting of the filter components, allows the coolant to be filtered by the filter screen before entering the spraying channel. This can intercept impurities in the coolant, prevent impurities from entering the subsequent spraying pipeline and causing blockage, and reduce the adverse effects of impurities on the workpiece machining surface and the cutting tool.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-4 A CNC machine tool cutting fluid spraying mechanism includes a magnetic base 100, a filter assembly 200, a fluid inlet pipe 300, and a universal bamboo-joint pipe 400. The filter assembly 200 is installed on the top of the magnetic base 100 and is used to filter the cutting fluid. The magnetic base 100 allows for quick fixation of the mechanism in a suitable position on the CNC machine tool without the need for a complex installation structure, thus improving the installation flexibility of the mechanism. The fluid inlet pipe 300 connects the input end of the filter assembly 200 to an external cutting fluid source, and can stably deliver external cutting fluid to the filter assembly 200. The universal bamboo-joint pipe 400 connects to the output end of the filter assembly 200, and can flexibly adjust the spraying direction according to processing requirements to ensure that the cutting fluid is accurately sprayed to the processing area.

[0037] like Figures 2-4As shown, in this utility model, the filter assembly 200 includes a base 210 and a cover 220. The cover 220 is radially mounted on the base 210, forming a compact assembly structure between the cover 220 and the base 210, reducing space occupation. A groove 212 is provided on the side end of the base 210 to provide installation space for the sleeve 213, and facilitates the connection between the subsequent channel and the external structure. The side wall of the groove 212 is provided with a sleeve 213 with a hollow cylindrical structure, which can provide stable assembly support for the cover 220 and ensure that the cover 220 is not easy to shake after installation. The cover 220 is fitted into the sleeve 213 and threadedly connected to the sleeve 213. The threaded connection facilitates the disassembly and assembly of the cover 220 and makes subsequent maintenance of the filter screen more convenient.

[0038] like Figure 3 As shown, specifically, the support 210 has a slot 217, a fluid inlet channel 214, a transverse channel 216, and a fluid outlet channel 215. The slot 217 is horizontally concave and is located on the side wall of the groove 212 inside the protrusion 213, which can position the insert plate 2214 and ensure that the insert plate 2214 is stable after installation. The fluid inlet channel 214 and the transverse channel 216 are both located on the outer surface of the support 210 and communicate with the side wall of the groove 212, providing channels for the flow of cutting fluid in the support 210 and realizing the orderly transmission of cutting fluid. The inner ends of the fluid inlet channel 214 and the transverse channel 216 extend into the protrusion 213, with the slot 217 as the... The center is symmetrically distributed vertically, with the inlet channel 214 located at the bottom. This distribution guides the cutting fluid to enter through the lower inlet channel 214, be filtered, and then flow out through the upper transverse channel 216, ensuring that the cutting fluid completely passes through the filtration process. The outlet channel 215 is located at the top of the stand 210 and connects to the transverse channel 216, guiding the filtered cutting fluid in the transverse channel 216 to the universal bamboo tube 400. The inlet pipe 300 connects to the inlet channel 214, ensuring that external cutting fluid accurately enters the inlet channel 214. The universal bamboo tube 400 connects to the outlet channel 215, allowing the filtered cutting fluid to smoothly enter the universal bamboo tube 400 for spraying.

[0039] like Figure 4As shown, further, a sleeve 221 is rotatably connected inside the cover 220; the sleeve 221 is a flat plastic structure, and its outer surface is tightly fitted to the inner wall of the cover 220, which can prevent unfiltered cutting fluid from flowing through the gap between the sleeve 221 and the inner wall of the cover 220, ensuring that the cutting fluid is filtered by the filter screen; a filter screen 2211 is provided inside the sleeve 221, which can intercept impurities in the cutting fluid and prevent impurities from entering the subsequent spray structure and causing blockage or affecting the machining quality. An insert plate 2214 is provided at the end near the stand 210. The insert plate 2214 is inserted into the slot 217, and the insert plate 2214 and the slot 217 are connected through the insert plate 2214 and the slot 217. The 7-piece set can fix the position of the sleeve 221 inside the cover 220, preventing the sleeve 221 from rotating with the flow of cutting fluid. The end of the sleeve 221 is provided with a convex shaft 2212, which passes through the end of the cover 220 and is fixed with a retaining ring 2213. The convex shaft 2212 provides support for the rotation of the sleeve 221, and the retaining ring 2213 can prevent the sleeve 221 from falling out of the cover 220. The sleeve 221 can rotate circumferentially around the convex shaft 2212 inside the cover 220. When cleaning or replacing the filter screen 2211, the position of the filter screen 2211 can be adjusted by rotating the sleeve 221, making the operation more convenient.

[0040] like Figures 1-3 As shown, in addition, the bottom of the stand 210 is integrally formed with a base plate 211. The integral structure enhances the connection strength between the stand 210 and the base plate 211, ensuring the stability of the stand 210 after installation. The base plate 211 is fixed to the top of the magnetic base 100 by bolts. The bolt connection method facilitates the disassembly and assembly of the stand 210 and makes subsequent maintenance of the internal channels of the stand 210 more convenient. The outer port of the liquid inlet channel 214 is threaded with a first pipe connector 2141, which can enhance the sealing of the connection between the liquid inlet pipe 300 and the liquid inlet channel 214 and prevent cutting fluid leakage. The end of the liquid inlet pipe 300 is sleeved and installed on the outer end of the first pipe connector 2141. The installation method simplifies the assembly steps of the inlet pipe 300; a plug 2161 is embedded at the outer port of the transverse channel 216 to seal the outer port of the transverse channel 216 and prevent the cutting fluid from leaking from the outer end of the transverse channel 216. At the same time, the plug 2161 can be removed for subsequent cleaning of the transverse channel 216; the top of the outlet channel 215 is threaded with a second pipe connector 2151, which can enhance the sealing of the connection between the universal bamboo tube 400 and the outlet channel 215 and prevent the cutting fluid from leaking. The inlet end of the universal bamboo tube 400 is sleeved and installed on the outer end of the second pipe connector 2151, which simplifies the assembly process of the universal bamboo tube 400.

[0041] like Figure 3As shown, it is worth noting that guide bevels 2171 are provided on both the top and bottom edges of the slot 217. These guide bevels 2171 guide the insertion of the insert plate 2214, allowing it to be inserted quickly and accurately into the slot 217, reducing the alignment time between the insert plate 2214 and the slot 217. The cover 220 is a transparent cylindrical structure, facilitating observation of the impurity accumulation on the filter screen 2211 inside the cover 220, enabling timely cleaning or replacement of the filter screen 2211. The first end is open, and the second end is closed. The open first end facilitates the installation and removal of the sleeve 221, while the closed second end prevents cutting fluid leakage from the end of the cover 220. External threads are provided on the outer circumferential surface of the first end of the cover 220, and internal threads are provided on the inner wall of the sleeve 213. The thread parameters of the external and internal threads are matched to ensure a sealed threaded connection between the cover 220 and the sleeve 213. To ensure safety and stability and prevent cutting fluid leakage, the insert plate 2214 protrudes from the head end of the cover 220, and the protrusion distance is greater than the depth of the sleeve 213. This ensures that when installing the cover 220, the insert plate 2214 can be inserted into the slot 217 before the cover 220 and the sleeve 213 are threaded together. The cover 220 can be positioned first by the cooperation between the insert plate 2214 and the slot 217, and then the threaded connection can be made, improving the installation accuracy of the cover 220. The cutting fluid flow path of the mechanism is as follows: external cutting fluid source → inlet pipe 300 → inlet channel 214 → lower half of the cover 220 horizontally separated by the sleeve frame 221 → filter screen 2211 in the sleeve frame 221 → upper half of the cover 220 horizontally separated by the sleeve frame 221 → transverse channel 216 → outlet channel 215 → universal bamboo joint pipe 400. This path ensures that the cutting fluid is filtered throughout the process and flows smoothly without any obvious stagnation areas.

[0042] In this embodiment, the CNC machine tool cutting fluid spraying mechanism is used as follows: First, the mechanism is fixed in a suitable position on the CNC machine tool using the magnetic base 100. Then, the inlet pipe 300 is connected to the external cutting fluid source and the first pipe connector 2141, and the universal bamboo joint pipe 400 is connected to the second pipe connector 2151 to complete the installation and connection of the mechanism. Then, the external cutting fluid enters the inlet channel 214 through the inlet pipe 300 and flows into the lower half of the cover 220. At this time, the cutting fluid comes into contact with the filter screen 2211 inside the sleeve 221, and the filter screen 2211 intercepts impurities in the cutting fluid. Next, the filtered cutting fluid enters the upper half of the cover 220 and flows into the outlet channel 215 through the transverse channel 216, and finally enters the universal bamboo joint pipe 400. Finally, the angle of the universal bamboo joint pipe 400 is adjusted according to the position of the processing area to ensure that the cutting fluid is accurately sprayed onto the processing area, thus completing the cutting fluid filtration and spraying process.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
