Description

Technical Field

[0001] This application relates to the field of grinding machine technology, and more specifically to a grinding machine cooling device. Background Technology

[0002] A grinding machine is a machine tool that uses an abrasive wheel to grind the surface of a workpiece. Most grinding machines use a high-speed rotating grinding wheel for grinding. Grinding machines include cylindrical grinding machines, and the grinding machine cooling system is a device used to cool the grinding wheel.

[0003] Patent document (CN212420925U) discloses a grinding machine cooling device, including a cooling assembly. The cooling assembly includes a water tank and a water pump. The water tank is placed on the ground and connected to a water supply outlet pipe. The end of the water supply outlet pipe away from the water tank is connected to the inlet of the water pump. The water pump is fixed to the upper surface of the water tank. The outlet of the water pump is connected to a spray pipe, which is fixedly connected to the grinding frame. The end of the spray pipe away from the water pump is connected to a nozzle, which faces the workpiece and the grinding wheel. A slag-collecting plate is fixed on the grinding machine base. A first inclined plate is fixed to the end of the slag-collecting plate near the grinding wheel. The end of the first inclined plate near the grinding wheel is higher than the end away from the grinding wheel. Multiple drainage holes are opened on the first inclined plate, and coolant can flow into the water tank through the drainage holes. It should be noted that the debris remains on the first inclined plate, while the coolant flows back to the water tank. It should also be noted that since grinding machines are mostly used for high-precision machining, the metal chips generated during the grinding process are in the form of granular powder. When the coolant is flushed, metal particles are mixed into the coolant. In the above solution, the metal particles are screened by the drainage holes on the inclined first plate. If the metal particles remain on the first inclined plate, they are more likely to accumulate on the first inclined plate and form a "dam" of metal particles, making it difficult to move to the push plate. Furthermore, the formation of the metal particle "dam" can easily block the drainage holes, resulting in the coolant not being discharged into the water tank.

[0004] Therefore, there is a need for a grinding machine cooling device that can filter metal particles in coolant, switch in time when metal particles clog the filter screen, and collect metal particles. Summary of the Invention

[0022] Schematic diagram of a grinding machine cooling device, for reference Figures 1 to 4 A preferred embodiment of the present invention provides a grinding machine cooling device, comprising a machine base 10, a clamping module 20, a grinding module 30, and a cooling mechanism 40.

[0023] It should be noted that, as Figure 1 and Figure 2As shown, the clamping module 20, the grinding module 30, and the cooling mechanism 40 are all mounted on the machine base 10. The clamping module 20 clamps the rotatable workpiece, and the grinding module 30 grinds the workpiece. In addition, the cooling mechanism 40 includes a spray gun 401, a liquid-particle separation mechanism 402, and a liquid storage tank 403. The spray gun 401 is located on the grinding module 30. The inlet of the liquid storage tank 403 is connected to the liquid-particle separation mechanism 402, and the outlet of the liquid storage tank 403 is connected to the spray gun 401. The machine base 10 has a discharge port 101, which is located between the clamping module 20 and the grinding module 30. The liquid-particle separation mechanism 402 is located below the discharge port 101 and includes four screening discs 4021, each of which is provided with a first filter screen 40211.

[0024] It should be noted that when the grinding module 30 is cutting the workpiece, the spray gun 401 sprays out coolant, which carries away metal particles and passes through the discharge port 101 and falls onto the screening plate 4021 below. By setting the first filter screen 40211 on the screening plate 4021, the coolant passes through the first filter screen 40211 and eventually flows back to the storage tank 403, while the metal particles in the coolant are retained in the first filter screen 40211. This prevents the coolant from being mixed with metal particles during recirculation, which could scratch the newly ground surface when it comes into contact with the workpiece.

[0025] However, after long-term filtration, the first filter screen 40211 on the screening disc 4021 retains too many metal particles, making it difficult for coolant to pass through the first filter screen 40211. In the prior art, a first filter screen 40211 is usually installed and needs to be replaced in time. However, in high-intensity continuous processing, if the first filter screen 40211 becomes clogged during the processing, replacing the first filter screen 40211 on-site will affect production efficiency. In this embodiment, by setting four screening discs 4021, when one screening disc 4021 is blocked, the screening disc 4021 is rotated by a predetermined angle, and another new screening disc 4021 is directed toward the discharge port 101, so as to realize timely switching of the first filter screen 40211 during the processing. However, when the new screening disc 4021 is directed toward the discharge port 101, the metal particles on the original screening disc 4021 that carried the metal particles may still contain residual coolant. If the metal particles are poured out directly, the residual coolant will be collected along with them.

[0026] Therefore, to ensure that the screening disc 4021 can rotate when the first filter screen 40211 on the screening disc 4021 becomes clogged, and to allow the residual coolant in the metal particles to be separated and collected uniformly, such as... Figures 1 to 3 As shown, the liquid-particle separation mechanism 402 also includes a first rotating shaft 4022, a drain baffle 4023, and a collection box 4024. The four screening discs 4021 are arranged in a ring array around the first rotating shaft 4022 and connected to the first rotating shaft 4022. It should be noted that the screening discs 4021 face the discharge port 101 and collect metal particles in the coolant and pass them through the coolant. When the metal particles accumulate and make it difficult for the coolant to pass through, the first rotating shaft 4022 rotates by a predetermined angle and drains the remaining coolant from the metal particles through the drain baffle 4023 located on one side of the liquid-particle separation mechanism 402. After the first rotating shaft 4022 rotates by a predetermined angle again, the drained metal particles fall into the collection box 4024.

[0027] More specifically, to ensure that the coolant flows into the storage tank 403 after passing through the first filter screen 40211, and to ensure that the screening disc 4021 can separate metal debris and residual coolant after rotating at a predetermined angle, such as Figure 1 and Figure 3 As shown, the first rotating shaft 4022 has four first channels 4025 arranged in a ring array. The first channels 4025 are connected to the inlet of the liquid storage tank 403. The first rotating shaft 4022 is rotatably mounted on the base 10. The collection box 4024 is located at the end of the screening disc 4021 away from the discharge port 101. The opening of one screening disc 4021 faces the discharge port 101. The opening of another screening disc 4021 opposite to this screening disc 4021 faces the collection box 4024. A drain baffle 4023 is provided on one side of one of the screening discs 4021 located between the two screening discs 4021. The drain baffle 4023 is arranged vertically and covers the opening of the screening disc 4021. A second filter screen 40231 is provided on the drain baffle 4023.

[0028] In addition, such as Figure 1 and Figure 3As shown, each of the screening discs 4021 has a concave arc cavity 40212, and both ends of the concave arc cavity 40212 have vertically arranged convex arc-shaped baffles 40213. The drain baffles 4023 are arc-shaped, and the radius of the inner arc surface of the drain baffle 4023 from the outer edge of the convex arc-shaped baffle 40213 to the central axis of the first rotating shaft 4022 is equal. In addition, the four screening discs 4021 are arranged in a ring array and their ends are connected to... The ends are fixedly connected in sequence. The distance between the two ends of each screening disc 4021 and the central axis of the first rotating shaft 4022 is equal to the radius of the inner arc surface of the drain baffle 4023 and the central axis of the first rotating shaft 4022. The connection between two adjacent screening discs 4021 has an arc surface 40214. When the screening disc 4021 rotates, the arc surface 40214 is attached to or separated from the inner arc surface of the drain baffle 4023.

[0029] It should be noted that when the coolant falls into the concave cavity 40212, it passes through the first filter screen 40211 and flows into the corresponding first channel 4025 on the first rotating shaft 4022 below, and then flows into the storage tank 403 along the first channel 4025; when the first filter screen 40211 on the sieve disc 4021 is blocked, the first rotating shaft 4022 rotates 90°, and at this time the sieve disc 4021 containing metal particles is blocked by the drain baffle 40. 23. Because both the screening disc 4021 and the drain baffle 4023 are vertically arranged, the metal particles on the screening disc 4021 accumulate at one end of the concave arc cavity 40212 under gravity. When the first rotating shaft 4022 rotates 90°, the other screening disc 4021, which has not collected metal particles or has collected only a small amount of metal particles, faces the discharge port 101, thus screening out the metal particles in the coolant for a period of time. During this time, the vertically arranged... The residual coolant in the metal particles on the screening disc 4021 passes through the second filter screen 40231, thereby draining the residual coolant from the metal particles and separating the coolant from the metal particles. When the first filter screen 40211 on the newly switched screening disc 4021 also becomes clogged, the first rotating shaft 4022 is rotated 90° again, and the newly switched screening disc 4021 repeats the draining process. The screening disc 4021, which had previously contained metal particles after draining, is then drained by the rotating shaft. After rotating 90° again, with the opening of the concave arc cavity 40212 facing the collection box 4024 and without any obstruction between them, the drained metal particles fall into the collection box 4024 under the influence of gravity. Once the metal particles in the collection box 4024 have been collected to a predetermined level, they can be removed and pressed into an iron disc by an external pressure mechanism for recycling. Furthermore, the draining baffle 4023 prevents the metal particles collected in the collection box 4024 from having a high liquid content. It is evident that, compared to the prior art, this application has the advantages of filtering metal particles from the coolant, timely switching when metal particles clog the filter, and collecting metal particles.

[0030] Furthermore, to achieve the following when the first filter 40211 becomes clogged: Figure 1 and Figure 4As shown, the first rotating shaft 4022 rotates circumferentially. The liquid-particle separation mechanism 402 also includes several second rotating shafts 4026, a displacement sensor 4027, and a first rotary drive device 4028. A second rotating shaft 4026 is rotatably installed in each of the first channels 4025. The second rotating shaft 4026 has several blades 40261. One end of the second rotating shaft 4026 has a cam portion 40262, and the displacement sensor 4027 is provided below the cam portion 40262. The wire of the displacement sensor 4027 passes through the center of the first rotating shaft 4022 and is electrically connected to the controller of the grinding machine. The output shaft of the first rotary drive device 4028 is fixedly connected to the first rotating shaft 4022.

[0031] It should be noted that when the grinding machine is running and processing a workpiece, the spray gun 401 continuously sprays coolant. When the first filter screen 40211 is not clogged, the coolant continuously passes through the first filter screen 40211 and flows into the first channel 4025, impacting the rotary vane 40261 and causing the second rotating shaft 4026 to rotate circumferentially. This, in turn, drives the cam part 40262 to rotate circumferentially, allowing the displacement sensor 4027 to obtain periodically changing distance parameters, which are continuously transmitted to the grinding machine's controller. However, when the first filter screen 40211 is clogged... When the filter screen 40211 is clogged, the coolant has difficulty passing through the first filter screen 40211 to flow into the first channel 4025 and impact the rotary blade 40261. At this time, the second rotating shaft 4026 does not rotate circumferentially, and the displacement sensor 4027 has difficulty continuously transmitting electrical signals to the grinding machine controller. At this time, the grinding machine controller sends an electrical signal to the first rotary drive device 4028 and causes the first rotating shaft 4022 to rotate circumferentially by 90°, so that when the first filter screen 40211 is clogged, the first rotating shaft 4022 rotates circumferentially.

[0032] Furthermore, to achieve the recovery of the drained residual coolant, such as... Figure 3 As shown, the liquid-particle separation mechanism 402 further includes a second channel 4029, one end of which faces the second filter screen 40231, and the other end is connected to the liquid storage tank 403.

[0033] Furthermore, since the width of the first rotating shaft 4022 is smaller than the width of the screening disk 4021, in order to increase the area of ​​the first filter screen 40211, the coolant, after passing through the first filter screen 40211, can completely flow into the first channel 4025, such as... Figure 3 As shown, each of the screening discs 4021 has a first water guide ramp 40215 on the side near the first rotating shaft 4022. In this embodiment, each screening disc has two symmetrically arranged first water guide ramps 40215.

[0034] Furthermore, to ensure that after the first rotating shaft 4022 rotates, the corresponding first channel 4025 can flow into the storage tank 403, such as... Figure 1 As shown, each of the first channels 4025 has a second water guide ramp 40251 at one end near the liquid storage tank 403, and a third water guide ramp 4031 is provided at the liquid inlet of the liquid storage tank 403. The third water guide ramp 4031 is spaced at a predetermined distance from the second water guide ramp 40251 in the height direction.

[0035] Furthermore, in this application, as Figure 1 As shown, the base 10 includes a base 102, a column 103, and an upper seat 104. The column 103 is located on the top surface of the base 102, and both ends of the column 103 are connected to the upper seat 104 and the base 102, respectively. The clamping module 20 includes two sliding seats 201. Both sliding seats 201 are slidably disposed on the upper seat 104 and face opposite directions. A tip 2011 is rotatably mounted on each sliding seat 201.

[0036] It should be noted that by making the bottom of the clamping module 20 almost unobstructed from the discharge port 101, the coolant can more easily fall into the screening plate 4021, making the clamping module 20 more suitable for clamping small and medium-sized workpieces; in addition, when installing the workpiece, the two top points are used to hold the two ends of the workpiece.

[0037] Furthermore, to facilitate the flow of coolant into the screening tray 4021, such as... Figure 2 As shown, the base 1022 also has two inclined surfaces 105, which are located on both sides of the material discharge port 101.

[0038] Furthermore, such as Figure 2 As shown, the grinding module 30 in this application further includes a grinding wheel 301 and a movable base 302. The movable base 302 is slidably disposed on the width direction of the base 102. The grinding wheel 301 is rotatably mounted on the movable base 302. The spray gun 401 is disposed on the movable base 302, and the nozzle of the spray gun 401 faces the grinding wheel 301. The workpiece is ground by the grinding wheel 301, and the movable base 302 is used to move the grinding wheel 301 closer to or further away from the workpiece.

[0039] In summary, the grinding machine cooling device described in the embodiments of this application is explained, which provides advantages such as being able to filter metal particles in the coolant, being able to switch in time when metal particles clog the filter screen, and being able to collect metal particles.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from these principles.
