Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a coolant circulation filtration structure for a fully automatic CNC grinding machine. Background Technology

[0002] In the machining process of fully automatic CNC grinding machines, coolant plays a crucial role in cooling the tool and workpiece, lubricating the machining interface, and flushing away cutting debris. Its circulation stability directly affects machining accuracy, tool life, and equipment operating efficiency. To prevent cutting debris, abrasive particles, and other impurities from causing workpiece scratches, tool wear, or pipeline blockage due to coolant circulation, a filtration structure must be installed in the coolant circulation system to intercept and filter impurities.

[0003] Existing CNC grinding machine coolant filtration structures mostly employ fixed filter screens and filter elements. While these achieve basic filtration, they have significant drawbacks: during filtration, impurities gradually adhere to the surface of the filter elements, causing blockages in the filtration channels. This leads to a decrease in coolant circulation flow and abnormal pressure. Due to the lack of effective blockage detection and early warning mechanisms, operators cannot monitor the blockage status of the filter elements in real time. Problems are typically detected indirectly through manual inspections observing flow changes and abnormal equipment shutdowns, resulting in a detection lag.

[0004] When the filter is severely clogged, it can lead to insufficient coolant supply, causing problems such as increased processing temperature and workpiece precision deviation. It can also damage components such as pumps and pipelines due to excessive circulation pressure, increasing equipment maintenance costs. Manual inspection is inefficient and prone to overlooking potential blockages due to human negligence, which cannot meet the high-efficiency, continuous, and intelligent processing requirements of fully automatic CNC grinding machines. Utility Model Content

[0005] The technical problem to be solved by this invention is the technical pain point of existing filter structures having delayed clogging warnings and relying on manual monitoring. To address this, we propose a coolant circulation filter structure for fully automatic CNC grinding machines.

[0006] To achieve the above objectives, this application adopts the following technical solution: a coolant circulation filtration structure for a fully automatic CNC grinding machine, comprising a body, a filter assembly installed on one side of the body, the filter assembly including an assembly tube, a filter disc built into the assembly tube, a contact rod fixedly connected to the side of the filter disc near the body, a pressure sensor provided at the end of the contact rod away from the filter disc, multiple mounting grooves opened in the inner wall of the assembly tube, fixing grooves opened on both sides of the mounting groove, a rotating rod built into the fixing groove, the two ends of the rotating rod being rotatably connected to the bottom of the inner cavity of the two fixing grooves, coil springs sleeved at both ends of the rotating rod, a toggle seat sleeved and fixedly attached to the surface of the rotating rod, and a receiving platform fixedly connected to the end of the toggle seat away from the rotating rod.

[0007] Preferably, a flange is fixedly connected to one end of the assembly tube, and the assembly tube is fixed to the body through the flange.

[0008] Preferably, multiple guide seats are fixedly connected around the filter disc.

[0009] Preferably, the inner wall of the assembly tube is provided with multiple guide grooves around its perimeter, and the guide seat is slidably connected to the groove wall.

[0010] Preferably, the tail of the pressure sensor is fixedly connected to a fixing frame, and the end of the fixing frame away from the pressure sensor is fixedly connected to the inner wall of the assembly tube.

[0011] Preferably, the fixing grooves on both sides are symmetrically distributed along the axis of the mounting groove.

[0012] Preferably, one end of the coil spring is fixedly connected to the rotating rod, and the other end of the coil spring is fixedly connected to the wall of the fixed groove.

[0013] Preferably, the receiving platform surface is in contact with the filter tray.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This utility model discloses a coolant circulation filtration structure adapted to a fully automatic CNC grinding machine, including a main body and a filter assembly installed on one side, realizing the dual functions of filtration and intelligent blockage detection. The assembly tube of the filter assembly has guide seats around the filter disc that slide in conjunction with guide grooves on the inner wall of the assembly tube, preventing water flow impact from causing displacement and affecting the filtration effect. The inner wall of the assembly tube has an installation groove and two side fixing grooves, and houses a rotating rod and a coil spring. A toggle seat on the rotating rod connects to a receiving platform and contacts the filter disc. The coil spring provides elastic restoring force, forming a stable auxiliary support. A contact rod on one side of the filter disc cooperates with a corresponding pressure sensor to form a blockage detection structure: when impurities accumulate on the filter disc, causing the filtration channel to narrow, the change in water flow resistance will cause the filter disc to slightly shift. This displacement is transmitted through the receiving platform and toggle seat to the rotating rod. Simultaneously, the contact rod applies pressure to the pressure sensor, which converts the pressure signal into an electrical signal, triggering an alarm via a wireless unit, achieving real-time blockage detection. Operators can clean or replace the filter discs in a timely manner to avoid insufficient coolant supply leading to increased processing temperature and workpiece precision deviations. It also prevents excessive circulating pressure from damaging the pump and pipelines, reducing maintenance costs and extending component lifespan. Requiring no frequent manual inspections, it is well-suited to the efficient and continuous intelligent processing needs of fully automatic CNC grinding machines, improving production efficiency while reducing labor intensity, and achieving intelligent control of the filtration process.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figures 1 to 5As shown, this utility model provides a technical solution: a coolant circulation filtration structure for a fully automatic CNC grinding machine, comprising a body 1, a filter assembly 2 installed on one side of the body 1, the filter assembly 2 including an assembly pipe 201, one end of the assembly pipe 201 being fixedly connected to a flange 202, the assembly pipe 201 being fixed to the body 1 via the flange 202, a filter disc 203 being built into the assembly pipe 201, multiple guide seats 204 being fixedly connected around the filter disc 203, multiple guide grooves 205 being formed around the inner wall of the assembly pipe 201, the guide seats 204 being slidably connected to the groove walls of the guide grooves 205, and the filter disc 203 being positioned on the side closest to the body 1. A contact rod 206 is fixedly connected. A pressure sensor 207 is installed at the end of the contact rod 206 away from the filter disc 203. A fixing bracket 208 is fixedly connected to the tail of the pressure sensor 207. The end of the fixing bracket 208 away from the pressure sensor 207 is fixedly connected to the inner wall of the assembly tube 201. The guide seats 204 around the filter disc 203 cooperate with the guide grooves 205 on the inner wall of the assembly tube 201, allowing the filter disc 203 to slide smoothly along the guide grooves 205. This facilitates the installation, disassembly, and maintenance of the filter disc 203 and ensures that the filter disc 203 maintains accurate positioning during filtration, preventing displacement due to water flow impact and affecting the filtration effect. A contact rod 206 is fixedly attached to the side of the filter disc 203 closest to the body 1. A pressure sensor 207 is correspondingly installed at the end of the contact rod 206. The pressure sensor 207 is firmly connected to the inner wall of the assembly tube 201 through the fixing bracket 208, providing a structural basis for clogging detection.

[0025] Multiple mounting slots 209 are formed on the inner wall of the assembly pipe 201. Fixing slots 210 are formed on both sides of the mounting slot 209. A rotating rod 211 is housed within each fixing slot 210. Both ends of the rotating rod 211 are rotatably connected to the bottom of the inner cavity of the fixing slots 210. A coil spring 212 is sleeved on both ends of the rotating rod 211. One end of the coil spring 212 is fixedly connected to the rotating rod 211, and the other end is fixedly connected to the wall of the fixing slot 210. A toggle seat 213 is fixedly fitted onto the surface of the rotating rod 211. A receiving platform 214 is fixedly connected to the end of the toggle seat 213 away from the rotating rod 211. The surface of the receiving platform 214 contacts the filter disc 203. The mounting slots 209 on the inner wall of the assembly pipe 201 provide installation space for the auxiliary support structure. The rotating rod 211 is housed within the fixing slots 210 on both sides of the mounting slot 209, and both ends of the rotating rod 211 are rotatably connected to the bottom of the inner cavity of the fixing slot 210. One end of a coil spring 212, sleeved at both ends of the rotating rod 211, is fixed to the rotating rod 211, and the other end is fixed to the wall of the fixing groove 210, providing elastic restoring force for the rotating rod 211. A receiving platform 214 is connected to the end of a toggle seat 213 fixed to the surface of the rotating rod 211. The platform 214 remains in contact with the filter disc 203. During normal filtration, the receiving platform 214 provides stable support to the filter disc 203 under the action of the coil spring 212. When impurities adhere to the surface of the filter disc 203, causing a change in resistance, the slight displacement of the filter disc 203 will cause the toggle seat 213 and the rotating rod 211 to rotate via the receiving platform 214. Combined with the interaction between the contact rod 206 and the pressure sensor 207, this enables precise sensing of the blockage state.

[0026] The sliding engagement of the filter disc 203 with the guide seat 204 and guide groove 205, combined with the detection structure of the contact rod 206 and pressure sensor 207, enables real-time sensing of impurity adhesion on the surface of the filter disc 203. When impurities gradually accumulate, causing the filtration channel to narrow, the water flow resistance on the filter disc 203 changes, thereby causing the contact rod 206 to exert pressure towards the pressure sensor 207. The pressure sensor 207 converts the pressure signal into an electrical signal, which, via a wireless unit, activates the alarm, achieving real-time detection of blockage. This breaks away from the traditional, lagging detection mode that relies on manual inspection, allowing operators to promptly grasp the working status of the filter and prevent the blockage problem from worsening.

[0027] The establishment of a clogging early warning mechanism fundamentally avoids a series of chain problems caused by severe clogging of the filter components. Timely clogging alerts allow operators to proactively clean or replace filter disc 203 before flow drops or abnormal pressure occur, preventing insufficient coolant supply from causing increased processing temperature and workpiece precision deviations. Simultaneously, it avoids hard damage to pumps, pipelines, and other components caused by excessive circulating pressure, significantly reducing equipment maintenance costs, extending the service life of related components, and ensuring the stable operation of the CNC grinding machine. The structure eliminates the need for frequent manual inspections, reducing the risk of clogging due to human error, and is fully compatible with the efficient, continuous, and intelligent processing requirements of fully automatic CNC grinding machines. It improves production efficiency, reduces manual labor intensity, and achieves intelligent control of the filtration process, making equipment operation more controllable and safer.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
