Description

Technical Field

[0001] This utility model relates to the field of cylindrical grinding machine technology, specifically to a cylindrical grinding machine with a cutting fluid recovery function. Background Technology

[0002] External cylindrical grinding machines are used to machine the outer surfaces of workpieces formed by the generatrices of cylindrical, conical, or other shapes, as well as the end faces of shaft shoulders. Cutting fluid is an industrial liquid used in metal cutting, grinding, and machining processes to cool and lubricate the cutting tools and workpieces. External cylindrical grinding machines are widely used and can machine various cylindrical and conical outer surfaces and shaft shoulder end faces. However, existing external cylindrical grinding machines cannot recycle or filter the cutting fluid during use, resulting in the cutting fluid mixing with waste chips and making reuse impossible.

[0003] According to the description in the patent announcement (CN218017923U) of an external cylindrical grinding machine with cutting fluid recovery function, the external cylindrical grinding machine with cutting fluid recovery function includes "external cylindrical grinding machine body, groove, recovery box" etc. to realize the recovery work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This cylindrical grinding machine with cutting fluid recovery function utilizes the grinding machine body, grooves, and recovery tank to achieve the recovery work. However, during use, the cutting fluid is first filtered through a first filter screen. But the cleaning brush can only clean the bottom of the first filter frame and cannot clean the side where the cutting fluid flows from top to bottom. This leads to the accumulation of impurities, which clogs the filter screen and affects the filtration effect. Furthermore, since the cutting fluid flows from top to bottom, the first filter screen of this grinding machine needs to be moved upwards to be removed, which is not convenient and affects the use effect. Therefore, this grinding machine needs to be improved. Utility Model Content

[0015] Compared with the prior art, this utility model provides an external cylindrical grinding machine with a cutting fluid recovery function, which has the following beneficial effects:

[0016] 1. This cylindrical grinding machine with cutting fluid recovery function, through its recovery mechanism, allows a portion of the cutting fluid to be recovered during use. This fluid flows through the recovery holes inside the grinding machine body and into the recovery tank via the water flow direction from the nozzle. When the water flow is too strong, some cutting fluid enters the extension frame. Combined with the connecting pipe, this allows the cutting fluid to be introduced into the recovery tank for centralized recovery. The filter frame inside the recovery tank filters the recovered cutting fluid. A second servo motor drives a unidirectional threaded rod to rotate, causing a cleaning brush to move within the filter frame. This effectively removes residual impurities from the filter frame, ensuring consistent filtration and reducing manual cleaning workload. Furthermore, the bidirectional threaded rod and scraper help to concentrate the cutting fluid in the extension frame towards the center at the end of grinding, improving the recovery effect. Two sets of filter frames with different internal filter hole sizes provide dual filtration of the cutting fluid, further enhancing its purity. The position of the baffle can be flexibly adjusted by rotating the adjusting shaft, controlling the opening and closing of the filter frame for easy maintenance and replacement.

[0017] 2. This cylindrical grinding machine with cutting fluid recovery function, through the set conveying mechanism, when the used cutting fluid is recovered and filtered under the action of the recovery box and the filter frame, the cutting fluid can be further conveyed to the distribution pipe through the conveying pipe under the action of the high pressure pump, and sprayed out through the nozzle, so as to further cool the grinding wheel on the cylindrical grinding machine body.

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-8This utility model provides a technical solution: an external cylindrical grinding machine with a cutting fluid recovery function, including an external cylindrical grinding machine body 1, a recovery mechanism 2 provided at the bottom front side of the external cylindrical grinding machine body 1, and a conveying mechanism 3 provided at the top of the external cylindrical grinding machine body 1;

[0033] The recycling mechanism 2 includes a base 21, which is fixedly connected to the bottom front side of the cylindrical grinding machine body 1. A protective door 22 is rotatably connected to the front side of the base 21. A support block 23 is fixedly connected to the top of the base 21. An extension frame 25 is fixedly connected to the top of the support block 23. The extension frame 25 is fixedly connected to the front side of the cylindrical grinding machine body 1. A connecting pipe 2991 is fixedly connected to the bottom of the extension frame 25. A first servo motor 24 is fixedly connected to the right side of the support block 23. A bidirectional threaded rod 27 is fixedly connected to the left side of the first servo motor 24. A scraper 26 is threadedly connected to the periphery of the bidirectional threaded rod 27. The scraper 26 is slidably connected inside the extension frame 25. A recycling box 28 is fixedly connected inside the base 21. A filter frame 29 is slidably connected. A second servo motor 292 is fixedly connected to the right side of the recycling bin 28. A one-way threaded rod 293 is fixedly connected to the left side of the second servo motor 292. A cleaning brush 295 is threadedly connected to the outer side of the one-way threaded rod 293. The cleaning brush 295 is set inside the filter frame 29. A slide rod 294 is slidably connected inside the cleaning brush 295. A rectangular frame 291 is fixedly connected to the right side of the recycling bin 28. A fixing rod 296 is fixedly connected inside the rectangular frame 291. A support frame 297 is fixedly connected to the bottom of the rectangular frame 291. An adjusting shaft 298 is threadedly connected inside the support frame 297. A baffle 299 is rotatably connected to the left side of the adjusting shaft 298. The baffle 299 is set in front of the filter frame 29.

[0034] The bidirectional threaded rod 27 is rotatably connected to the inside of the support block 23 on the left side. The connecting pipe 2991 is fixedly connected to the top of the base 21. The top of the recovery box 28 is fixedly connected to the top of the base 21, which facilitates the recovery of the cutting fluid under the action of the recovery box 28. The unidirectional threaded rod 293 is rotatably connected to the inside of the recovery box 28 on the left side. The slide rod 294 is fixedly connected to the inside of the recovery box 28. The baffle 299 is slidably connected to the outside of the fixed rod 296. The internal part of the cylindrical grinding machine body 1 is provided with a recovery hole, which is circular, so as to limit the filter frame 29 under the action of the baffle 299.

[0035] The bottom of the cleaning brush 295 is in contact with the bottom of the filter frame 29, and the rear side of the baffle 299 is in contact with the front side of the filter frame 29, so that the impurities attached to the bottom of the filter frame 29 can be cleaned by the action of the cleaning brush 295. There are two sets of filter frames 29, which are slidably connected to the recovery box 28. The filter holes inside the two sets of filter frames 29 are different in size, so that the filtration effect of the cutting fluid can be improved by setting two filter frames 29.

[0036] Example 2

[0037] Please see Figure 1-8 Furthermore, based on Embodiment 1, the conveying mechanism 3 further includes a conveying pipe 32, which is fixedly connected to the left side of the recycling box 28. A high-pressure pump 31 is fixedly connected to the periphery of the conveying pipe 32. A diversion pipe 33 is fixedly connected to the top and bottom of the conveying pipe 32. A nozzle 35 is fixedly connected to the bottom of the diversion pipe 33. A mounting base 34 is fixedly connected to the rear side of the diversion pipe 33. The mounting base 34 is fixedly connected to the cylindrical grinding machine body 1. The conveying pipe 32 passes through the cylindrical grinding machine body 1 and the base 21. The high-pressure pump 31 is fixedly connected to the bottom of the base 21, which facilitates the reuse of the cutting fluid after use under the action of the high-pressure pump 31.

[0038] In actual operation, when this device is in use, when the cylindrical grinding machine body 1 is in use, a portion of the cutting fluid will flow through the recovery hole inside the cylindrical grinding machine body 1 and the base 21 along the water flow direction of the nozzle 35 into the recovery tank 28 for recovery. When the water flow is too large, a portion of the cutting fluid will enter the extension frame 25. With the help of the connecting pipe 2991, the cutting fluid can be introduced into the recovery tank 28 to achieve centralized recovery of the cutting fluid. When the cutting fluid enters the recovery tank 28, the filter frame 29 inside the recovery tank 28 can filter the recovered cutting fluid. 9 is equipped with two sets of filters with different internal filter hole sizes, which can perform dual filtration of cutting fluid and further improve the purity of the recovered cutting fluid. During the filtration process, the second servo motor 292 drives the one-way threaded rod 293 to rotate, which in turn drives the cleaning brush 295 to move. The cleaning brush 295 slides around the slide bar 294 and moves within the filter frame 29, which can promptly clean the impurities remaining on the filter frame 29, ensuring the durability of the filtration effect and reducing the amount of manual cleaning work.

[0039] After double filtration, the cutting fluid is stored at the bottom of the recovery tank 28. Under the action of the high-pressure pump 31, the cutting fluid can be further transported to the distribution pipe 33 through the delivery pipe 32 and sprayed out through the nozzle 35, so as to further cool the grinding wheel on the external cylindrical grinding machine body 1, and reuse it to save resources.

[0040] When the grinding work is finished, the scraper 26 connected to the outer thread of the one-way threaded rod 293 can be moved towards the center in the extension frame 25 by the first servo motor 24 to avoid the residue of cutting fluid and improve the recycling effect.

[0041] When the filter frame 29 needs to be removed for cleaning, simply rotate the adjusting shaft 298 to move the baffle 299 and slide it around the fixed rod 296, moving the baffle 299 away from the front of the filter frame 29. This will release the limiting effect on the filter frame 29, allowing it to be removed for cleaning.
