[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0038] like Figures 1 to 7 As shown, this application provides a grinding machine. The grinding machine includes a grinding machine body 10 and a protective device 20. The protective device 20 includes a housing assembly 21 and a base assembly 22. The base assembly 22 is mounted on the bottom end of the housing assembly 21 and forms a protective space with the housing assembly 21. The grinding machine body 10 is mounted within the protective space. A liquid collection structure 221 is provided on the side of the base assembly 22 near the protective space. The liquid collection structure 221 is located between the outer periphery of the grinding machine body 10 and the inner wall of the protective space.

[0039] In this embodiment, a liquid collection structure 221 is provided on the side of the base assembly 22 near the protective space. The liquid collection structure 221 can effectively collect the processing liquids such as coolant flowing out of the grinding machine body 10 during the grinding process, preventing the processing liquids from flowing directly onto the ground and causing pollution. This effectively maintains the cleanliness of the work area, reduces damage to the ground environment, and meets the requirements of environmental protection and workshop cleanliness. At the same time, the housing assembly 21 and the base assembly 22 enclose the grinding machine body 10 within the protective space, which can effectively prevent the debris generated by the grinding machine body 10 during the grinding process from flying outside the protective space, reducing the risk of workers being scratched by flying debris, and also facilitating subsequent debris cleaning.

[0040] like Figure 3 As shown, the liquid collection structure 221 further includes a first groove 2211. The first groove 2211 is recessed on the side of the base assembly 22 facing the protective space and communicates with the protective space. During the grinding process, the processing liquids such as coolant can naturally collect from the grinding machine body 10 within the protective space into the first groove 2211 under the action of gravity, effectively preventing the processing liquid from flowing and spreading randomly. The first groove 2211 can collect the processing liquid in a concentrated manner, reducing the possibility of processing liquid leaking to the ground, effectively preventing processing liquid from flowing to the ground and causing pollution, and also improving the collection efficiency of processing liquid. In particular, the method of using a recessed setting to form the first groove 2211 to collect processing liquid is convenient for the processing and manufacturing of the first groove 2211, which can reduce the manufacturing cost of the first groove 2211.

[0041] Furthermore, the length of the first groove 2211 extends along the outer periphery of the grinding machine body 10 in an annular structure. This arrangement can significantly increase the liquid collection range of the first groove 2211. Regardless of whether the processing liquid, such as coolant, flows out or splashes from any direction or part of the grinding machine body 10, the annular first groove 2211 can effectively collect the processing liquid, greatly reducing the risk of leakage and pollution.

[0042] like Figure 4As shown, the base assembly 22 further includes a first disc 222 and a second disc 223. The first disc 222 is provided with a clearance hole 2221. The clearance hole 2221 is adapted to the outer periphery of the bottom of the grinding machine body 10, and the inner wall surface of the clearance hole 2221 is tightly fitted with the outer wall surface of the grinding machine body 10. A first groove 2211 is provided on the side of the first disc 222 near the protective space. The base assembly 22 adopts a double-layer structure of the first disc 222 and the second disc 223, which can further reduce the risk of leakage of processing liquids such as coolant to the ground and cause pollution, and improve the protection capability of the grinding machine. The inner wall of the clearance hole 2221 fits tightly against the outer wall of the grinding machine body 10, effectively preventing coolant and other processing fluids from leaking out from the connection between the grinding machine body 10 and the first disc 222. This further ensures that the coolant and other processing fluids flow as much as possible into the first groove 2211, effectively preventing leakage of coolant and other processing fluids from the gap between the grinding machine body 10 and the first disc 222 and contaminating the ground. This improves the anti-leakage effect of the base assembly 22 on the processing fluid. In addition, the tight fit between the inner wall of the clearance hole 2221 and the outer wall of the grinding machine body 10 provides an accurate installation reference for the base assembly 22, ensuring that the base assembly 22 can be accurately installed in the predetermined position. The clearance hole 2221 also has a certain limiting function, reducing the lateral displacement of the grinding machine body 10 caused by vibration, external forces, and other factors during grinding, which can enhance the overall stability of the grinding machine and ensure that the grinding process can be carried out stably and accurately. The second disc 223 is offset to the outside of the first groove 2211 and connected to the housing assembly 21. The second disc 223 can provide stable support for the first disc 222, ensuring that the base assembly 22 itself is more stable. The connection between the first disc 222 and the second disc 223 is tighter and more reliable, which can better withstand the various forces generated during the operation of the grinding machine body 10, ensuring the structural integrity of the entire protective device 20 and providing a stable and reliable support foundation for the grinding machine body 10.

[0043] like Figure 5As shown, the first disc 222 further includes multiple first connecting segments 2222. A second groove 2223 is recessed on each of the first connecting segments 2222. The second disc 223 includes multiple second connecting segments 2231. Each of the multiple second connecting segments 2231 is fitted onto the outer side of the multiple first connecting segments 2222 in a one-to-one correspondence. The base assembly 22 also includes a splicing structure. A sealing element is provided between adjacent first connecting segments 2222, and adjacent first connecting segments 2222 are detachably spliced ​​together through the splicing structure, allowing their respective second grooves 2223 to communicate with each other to form a first groove 2211. Adjacent second connecting segments 2231 are detachably spliced ​​together through the splicing structure. The modular design of the first disc 222 and the second disc 223 facilitates transportation, installation, and disassembly, effectively reducing transportation costs and space requirements of the first disc 222 and the second disc 223. Workers can also assemble and connect the first connecting section 2222 and the second connecting section 2231 more flexibly according to the actual installation environment and operating space. The modular design of the first disc 222 and the second disc 223 also facilitates maintenance, eliminating the need to disassemble the entire base assembly 22, reducing maintenance difficulty, saving time and effort, and lowering maintenance costs. The modular design of the first disc 222 and the second disc 223 also provides high flexibility. By changing the length and number of the first connecting section 2222 and the second connecting section 2231, the size of the base assembly 22 can be flexibly adjusted, allowing the base assembly 22 to be flexibly adapted to various specifications of the grinding machine body 10, meeting diverse production requirements and further expanding the applicability of the grinding machine. The second grooves 2223 of each first connecting section 2222 are interconnected to form a first groove 2211, ensuring the continuity of the flow of processing fluids such as coolant within the first groove 2211. The processing fluid can smoothly converge along the second grooves 2223 of each first connecting section 2222, ensuring that the processing fluids such as coolant are effectively collected and preventing leakage that could pollute the ground environment. Adjacent second connecting sections 2231 are detachably spliced ​​together via a splicing structure. Multiple second connecting sections 2231 are fitted onto the outside of the corresponding first connecting section 2222, further reinforcing the first disc body 222 and collectively improving the overall structural stability of the base assembly 22. This ensures that the base assembly 22 can better withstand the vibrations, pressures, and other external forces generated during the grinding process of the grinding machine body 10, guaranteeing long-term stable operation of the grinding machine. The sealing element can seal the gap between adjacent first connecting sections 2222, further preventing the leakage of processing fluids such as coolant. The sealing element can be a sealing ring, sealing gasket, sealing flange, etc., and this embodiment is not limited to it.

[0044] Furthermore, the splicing structure includes a first splicing piece 2241, a second splicing piece 2242, and a locking member. One of two adjacent first connecting segments 2222 is provided with the first splicing piece 2241, and the other of two adjacent first connecting segments 2222 is provided with the second splicing piece 2242. The second splicing piece 2242 and the first splicing piece 2241 have a first position of close contact and a second position of separation. The locking member locks the first splicing piece 2241 and the second splicing piece 2242 in the first position or unlocks them to the second position. Workers only need to align the corresponding first splicing pieces 2241 and second splicing pieces 2242 on two adjacent first connecting segments 2222, ensuring the first splicing pieces 2241 and second splicing pieces 2242 are in the first position of close contact, and then use the locking member to lock them in place, thus completing the splicing assembly of the first connecting segment 2222. The operation steps for fixing the connection using this splicing structure are clear and simple, reducing the difficulty of on-site assembly of the base assembly 22, improving installation efficiency, and facilitating disassembly and maintenance. Specifically, the first splicing piece 2241 has a first through hole, and the second splicing piece 2242 has a second through hole corresponding to the first through hole. A locking member passes through the first and second through holes to lock the first splicing piece 2241 and the second splicing piece 2242 in a first position. It is understood that the specific implementation of the splicing structure is not limited to this, and this embodiment is not the only one.

[0045] Furthermore, one of the two adjacent second connecting segments 2231 is provided with a first splicing piece 2241, and the other of the two adjacent second connecting segments 2231 is provided with a second splicing piece 2242. The second splicing piece 2242 and the first splicing piece 2241 have a first position of close contact and a second position of separation. The locking member locks the first splicing piece 2241 and the second splicing piece 2242 in the first position or unlocks them to the second position. Through the first splicing piece 2241, the second splicing piece 2242 and the locking member, the two adjacent second connecting segments 2231 can also be connected and fixed together or disassembled and separated. This arrangement makes the base assembly 22 more flexible and facilitates the disassembly and installation of the base assembly 22.

[0046] In addition, glue can be applied between the first splicing piece 2241 and the second splicing piece 2242 to seal the gap between adjacent second connecting sections 2231, further preventing processing liquids such as coolant from leaking out of the first groove 2211.

[0047] Furthermore, the liquid collection structure 221 also includes a liquid outlet channel 2212. The liquid outlet channel 2212 is disposed through the first disc 222 and the second disc 223 and communicates with the first groove 2211. The grinding machine also includes a cooling system. The cooling system is disposed within the protective space and communicates with the liquid outlet channel 2212. The liquid outlet channel 2212 connects the coolant and other processing liquids collected in the first groove 2211 to the cooling system, allowing the collected processing liquids to re-enter the cooling system for recycling. During the processing of the grinding machine body 10, the amount of coolant used is often large. This recycling method can effectively reduce the amount of coolant replenishment, reduce coolant consumption costs, and achieve efficient resource utilization. In particular, during the grinding process of the grinding machine body 10, the outlet of the cooling system can be located near the grinding wheel to ensure that the coolant can continuously and effectively remove the heat generated by the workpiece and the grinding wheel, avoiding problems such as workpiece overheating and deformation and excessive wear of the grinding wheel due to insufficient coolant, thereby ensuring processing accuracy and quality and improving the product qualification rate.

[0048] Furthermore, the height of the bottom of the first groove 2211 near the liquid outlet channel 2212 is lower than the height of the bottom of the first groove 2211 away from the liquid outlet channel 2212. After the processing liquid such as coolant flows into the first groove 2211, it will automatically converge and flow towards the liquid outlet channel 2212 under the action of gravity. This natural flow method does not require additional external force, reducing equipment costs and energy consumption, while also ensuring that the processing liquid such as coolant can flow smoothly and quickly to the liquid outlet channel 2212, thereby improving the overall efficiency of liquid collection and transportation and minimizing the accumulation and residue of liquid in the first groove 2211.

[0049] Furthermore, the inclination angle between the bottom of the first groove 2211 near the liquid outlet channel 2212 and the bottom of the first groove 2211 away from the liquid outlet channel 2212 is A, which satisfies the relationship: 0.5°≤A≤1°. For example, A can be selected from 0.5°, 0.6°, 0.7°, 0.8°, 0.9°, 1.0°, etc. The first groove 2211 has a certain inclination angle, allowing the coolant and other processing liquids to flow smoothly to the liquid outlet channel 2212 under the action of gravity. This setting ensures that the coolant and other processing liquids can be orderly collected in the liquid outlet channel 2212, avoiding stagnation and accumulation of the coolant and other processing liquids in the first groove 2211, improving the efficiency of liquid collection and discharge, and effectively preventing the processing liquids from leaking to the ground due to prolonged retention in the first groove 2211. Furthermore, the flow of processing fluids such as coolant in the first groove 2211 is relatively gentle, allowing larger debris and other impurities to settle at the bottom, preventing blockage of the outlet channel 2212. If A < 0.5°, the flow velocity of the processing fluid under gravity will be very slow, and the fluid may accumulate at the end furthest from the outlet channel 2212, failing to be drained from the first groove 2211 in a timely manner. In high-efficiency grinding machine processing scenarios requiring rapid collection and recycling of coolant, excessively slow drainage speeds may lead to low coolant collection efficiency, failing to meet the timely coolant supply requirements of the cooling system. If the processing fluid cannot be drained from the first groove 2211 in a timely manner, it may overflow due to excessive fluid, polluting the ground environment around the grinding machine. If A > 1°, the flow velocity of the processing fluid under gravity will be too fast, and a large tilt angle can easily cause turbulence within the first groove 2211. Turbulence increases the disorder of the processing fluid flow, preventing it from flowing smoothly to the outlet channel 2212. In turbulent conditions, the processing fluid is likely to splash, and some of it may spill out of the first groove 2211 and contaminate the ground. The processing fluid will exert a significant impact force on the wall of the first groove 2211 and the inlet of the outlet channel 2212, which may lead to severe wear on the inner wall of the first groove 2211 over a long period of time. A large tilt angle may also cause large debris and other impurities to clog the outlet channel 2212, which is not conducive to the collection of processing fluids such as coolant.

[0050] like Figures 6 to 7As shown, the housing assembly 21 further includes multiple plates 211, which are arranged to form a mounting groove 212. Adjacent plates 211 are detachably connected, and a base assembly 22 covers the opening at the bottom of the mounting groove 212 to form a protective space. The modular design of the housing assembly 21 facilitates transportation, installation, and disassembly, effectively reducing transportation costs and space requirements. Workers can also assemble the housing assembly 21 more flexibly according to the actual installation environment and operating space. The modular design also facilitates maintenance, eliminating the need to disassemble the entire housing assembly 21, reducing maintenance difficulty, time and labor costs, and overall maintenance efficiency. Furthermore, the modular design offers high flexibility; by changing the length and number of housing assemblies, the dimensions of the housing assembly 21 can be flexibly adjusted, allowing it to adapt to various specifications of the grinding machine body 10, meeting diverse production requirements and further expanding the applicability of the grinding machine. After multiple plates 211 are arranged to form a mounting groove 212, they together with the base assembly 22 covering the bottom opening of the mounting groove 212 to form a protective space. This arrangement makes the base assembly 22 and the housing assembly 21 detachable, facilitating maintenance, assembly, and disassembly of the base assembly 22 and the housing assembly 21. The base assembly 22 covering the opening of the mounting groove 212 also improves the sealing of the protective space, preventing processing liquids such as coolant and processing debris from escaping. In addition, the good sealing of the protective space can effectively prevent liquids, dust, etc. outside the protective device 20 from damaging and contaminating the grinding machine body 10.

[0051] A protective door mounting opening 213 is provided between two adjacent plates 211, and a protective door 214 is installed between the two adjacent plates 211. The protective door 214 has a closed position that slides to close the protective door mounting opening 213 and an open position that avoids the protective door mounting opening 213. A safety lock 216 is provided between the protective door 214 and the plate 211. The safety lock 216 ensures that the protective door 214 cannot be accidentally opened during the operation of the grinding machine body 10, preventing personnel from accidentally entering and effectively improving the safety of the grinding machine.

[0052] An observation window 215 may also be provided on the plate 211, with transparent explosion-proof glass embedded in the window 215, allowing operators to easily observe the operation of the grinding machine body 10. The explosion-proof glass has strong impact resistance, protecting against impacts from coolant or workpiece debris during the operation of the grinding machine body 10, thus helping to protect the safety of the operators. The plate 211 may be made of sheet metal to ensure that the protective device 20 has high structural strength. A coating may be applied to the interior of the sheet metal structure near the protective space to reduce the corrosion of the housing assembly 21 by the coolant.

[0053] like Figures 1 to 7As shown, this application has the following beneficial effects: 1. Significantly improved waterproof performance. The base assembly 22 of this application adopts a first disc 222 and a second disc 223, and is provided with a first groove 2211, which can effectively prevent coolant leakage, avoid external liquid from entering the protective space, reduce corrosion of components in the protective space, and maintain a clean working environment. Compared with the traditional single-layer structure, the base assembly 22 of this utility model significantly improves the collection and return efficiency of coolant, and extends the service life of the grinding machine. 2. Significantly improved safety. The protective door 214 and the observation window 215 are both equipped with safety locks 216 to ensure that the protective door 214 cannot be accidentally opened during the operation of the grinding machine body 10, avoid personnel accidentally touching dangerous areas, and effectively improve operational safety. An observation window 215 can also be set on the protective door 214. The explosion-proof glass embedded in the observation window 215 has strong impact resistance and can resist the impact of coolant or workpiece debris during the operation of the grinding machine body 10, protecting the safety of the operator. 3. Significantly improved maintenance efficiency. The housing assembly 21 adopts a modular design, allowing for individual disassembly and replacement. Installation and maintenance of each panel are more convenient, eliminating the need for overall disassembly and significantly reducing maintenance complexity and equipment downtime. 4.
