Description

Technical Field

[0001] This utility model belongs to the field of machining center technology, and specifically relates to an adjustable cooling water distribution device for machining centers. Background Technology

[0002] In existing machining centers, cooling water is often required to cool the cutting tools during machining. However, as the cooling water flows over the workpiece, it easily mixes with the lubricating oil inside the tool. To enable the cooling water to be recycled, a separator is generally needed to separate the oil and water in the cooling water.

[0003] Currently, Chinese utility model patent CN220887115U discloses an oil-water separation device for machining centers. When cooling water is mixed with oil, the oil floats on top. Therefore, existing cooling water diversion devices typically install the oil-water pipe at the top of the cooling water and the return pipe at the bottom. This allows the oil-water pipe to drain the floating oil from the top, while the return pipe drains the cooling water from the bottom. However, this method is ineffective at removing floating oil when the cooling water level changes. Changes in the cooling water level cause changes in the oil level, and the fixed oil-water pipe cannot move with the oil level, thus reducing the effectiveness of diverting oil from the cooling water. Furthermore, when the cooling water flows over the cutting tool for cooling, it can easily wash away machining debris from inside the workpiece, which then flows into the diversion device. Existing diversion devices are not convenient for cleaning workpiece debris from inside the cooling water, easily leading to blockages in the cooling water pipes over time. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable cooling water diversion device for machining centers, which has the advantages of allowing the oil-stained pipes to change with the liquid level and facilitating the cleaning of workpiece debris in the cooling water.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable cooling water distribution device for a machining center, comprising a distribution box, wherein a cooling water inlet and an oil outlet are respectively opened at the top and bottom of the distribution box, an oil pipe is slidably connected inside the oil outlet, a fixing plate is welded to the top of the oil pipe, an annular airbag sleeved with the oil pipe is bonded to the bottom of the fixing plate, a through hole is opened at one end of the oil pipe near the fixing plate, and a cooling water return port is opened on one side of the bottom of the distribution box.

[0006] The above technical solution utilizes the buoyancy of an annular airbag within the cooling water and oil contaminants to move the oil contaminant pipe up and down inside the distribution box. This ensures that even with changes in the cooling water level, the through-hole remains at the top of the cooling water surface, allowing the oil contaminant layer to be discharged through the oil contaminant outlet, thus guaranteeing efficient separation of cooling water and oil contaminants. The cooling water is filtered through a filter screen, and a pusher plate slides back and forth on top of the filter screen, pushing the filtered workpiece debris into a collection groove for storage. This facilitates the cleaning of workpiece debris from the cooling water and prevents blockage of the cooling water pipes.

[0007] The present invention is further configured such that: a filter screen is bolted to the top of the inner cavity of the distribution box; a motor is bolted to the top of the distribution box near the cooling water return port; a threaded rod rotatably connected to the distribution box is bolted to the output end of the motor; a threaded sleeve is threaded onto the surface of the threaded rod; a push plate slidably connected to the filter screen is welded to the bottom of the threaded sleeve; and a collection groove is provided on the side of the filter screen near the motor.

[0008] By adopting the above technical solution, the pusher plate slides back and forth on the top of the filter screen to push the filtered workpiece debris into the collection groove for storage, thereby facilitating the cleaning of workpiece debris in the cooling water.

[0009] The present invention is further configured such that a sealing ring is bonded to the top of the inner cavity of the oil outlet, which is slidably sleeved with the oil pipe.

[0010] By adopting the above technical solution, the sealing between the surface of the oily pipe and the inside of the oily outlet is improved, preventing the cooling water inside the distribution box from flowing out from the inside of the oily outlet.

[0011] The present invention is further configured such that an observation window is bolted to the other side of the top of the diversion box.

[0012] The above technical solution facilitates observation of the filtration and distribution status of the cooling water inside the distribution box from the outside.

[0013] The present invention is further configured such that: a chip discharge port is provided on the side of the distributor box near the motor, which is used in conjunction with the collection groove.

[0014] By adopting the above technical solution, the workpiece debris inside the collection groove can be discharged outward by opening the chip discharge port, thus preventing accumulation.

[0015] The present invention is further configured such that the interior of the cooling water inlet, the oil outlet, the cooling water return port, and the chip discharge port are all threaded with sealing caps.

[0016] By adopting the above technical solution, the interior of the cooling water inlet, oil outlet, cooling water return port, and chip discharge port can be sealed, thereby preventing dust from entering the inside of the distributor box when it is not in use.

[0017] The present invention is further configured such that: a positioning rod that is bolted to the bottom of the threaded rod and slidably connected to the push plate is located in the inner cavity of the diverter box.

[0018] The above technical solution guides the sliding of the push plate, improving the stability of the push plate sliding on top of the filter screen.

[0019] The present invention is further configured such that: the top of the threaded rod is provided with an arc-shaped cover bolted to the inside of the diverter box.

[0020] By adopting the above technical solution, the top of the threaded rod is shielded and protected to prevent cooling water from washing away the surface of the threaded rod.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The buoyancy of the annular airbag in the cooling water and oil sludge causes the oil sludge pipe to move up and down inside the distribution box. This ensures that even if the cooling water level changes, the through-hole remains at the top of the cooling water surface, allowing the oil sludge layer on the cooling water to be discharged outwards through the oil sludge outlet, thus guaranteeing efficient separation of cooling water and oil sludge.

[0023] 2. The cooling water is filtered through a filter screen, and a pusher plate slides back and forth on top of the filter screen to push the filtered workpiece debris into the collection groove for storage. This facilitates the cleaning of workpiece debris from the cooling water and prevents blockage of the cooling water pipes. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 4 An adjustable cooling water diversion device for a machining center includes a diversion box 1. The top and bottom of the diversion box 1 have cooling water inlets 2 and oil outlets 4, respectively. An oil pipe 5 is slidably connected inside the oil outlet 4. A fixing plate 6 is welded to the top of the oil pipe 5, and an annular airbag 7, which is fitted onto the bottom of the fixing plate 6, is connected to the oil pipe 5. A through hole 8 is opened at one end of the oil pipe 5 near the fixing plate 6. A cooling water return port 3 is opened on one side of the bottom of the diversion box 1. The buoyancy of the annular airbag 7 in the cooling water and oil causes the oil pipe 5 to move up and down inside the diversion box 1. Therefore, even if the cooling water level changes, the through hole 8 remains at the top of the cooling water level, allowing the oil layer on the cooling water to be discharged outwards through the oil outlet 4, ensuring efficient diversion of cooling water and oil.

[0032] refer to Figure 2 A sealing ring 15 is bonded to the top of the inner cavity of the oil outlet 4, which slides and fits with the oil pipe 5. This improves the sealing between the surface of the oil pipe 5 and the inside of the oil outlet 4, preventing the cooling water inside the distribution box 1 from flowing out of the oil outlet 4.

[0033] refer to Figure 1 An observation window 16 is bolted to the other side of the top of the distribution box 1. This allows for observation of the filtration and distribution status of the cooling water inside the distribution box 1 from the outside.

[0034] Brief description of operation: Cooling water enters the distributor box 1 through the cooling water inlet 2. The buoyancy of the oil-sludge pipe 5 within the cooling water and oil, facilitated by the annular airbag 7, moves the oil-sludge pipe 5 upwards. This causes the through-hole 8 to be positioned at the top of the cooling water surface, allowing the oil layer on the cooling water to flow through the through-hole 8 into the oil-sludge pipe 5, and then outwards from the oil-sludge outlet 4. Simultaneously, cooling water can be discharged outwards through the cooling water return port 3 at the bottom. When the cooling water level changes, the buoyancy of the annular airbag 7 causes the oil-sludge pipe 5 to slide up and down inside the oil-sludge outlet 4, thus keeping the through-hole 8 at the top of the cooling water surface, continuously discharging the oil from the cooling water.

[0035] Example 2:

[0036] refer to Figure 1 , Figure 2 , Figure 3 An adjustable cooling water distribution device for a machining center is disclosed. A filter screen 13 is bolted to the top of the inner cavity of a distribution box 1. A motor 9 is bolted to the top of the distribution box 1 near the cooling water return port 3. A threaded rod 10, rotatably connected to the distribution box 1, is bolted to the output end of the motor 9. A threaded sleeve 11 is threaded onto the surface of the threaded rod 10. A push plate 12, slidably connected to the filter screen 13, is welded to the bottom of the threaded sleeve 11. A collection groove 14 is provided on the side of the filter screen 13 near the motor 9. Cooling water is filtered through the filter screen 13, and the push plate 12 slides back and forth on top of the filter screen 13, pushing the filtered workpiece debris into the collection groove 14 for storage. This facilitates the cleaning of workpiece debris from the cooling water and prevents blockage of the cooling water pipes.

[0037] refer to Figure 1 , Figure 2 The diverter box 1 has a chip discharge port 17 on the side near the motor 9, which works in conjunction with the collection groove 14. The chip discharge port 17 can be opened to discharge workpiece chips from inside the collection groove 14, preventing accumulation.

[0038] refer to Figure 1 , Figure 2 , Figure 3 The cooling water inlet 2, oil outlet 4, cooling water return port 3, and chip discharge port 17 are all threaded with sealing caps 18. These caps can seal the interior of the cooling water inlet 2, oil outlet 4, cooling water return port 3, and chip discharge port 17, thereby preventing dust from entering the interior of the distributor box 1 when it is not in use.

[0039] refer to Figure 2 , Figure 3 The inner cavity of the diversion box 1 is fitted with a positioning rod 19 that is bolted to the bottom of the threaded rod 10 and slides through the push plate 12. This guides the sliding of the push plate 12 and improves the stability of the push plate 12 sliding on top of the filter screen 13.

[0040] refer to Figure 2 , Figure 3 The top of the threaded rod 10 is provided with an arc-shaped cover 20 that is bolted to the inside of the distribution box 1. This covers and protects the top of the threaded rod 10 to prevent cooling water from washing away the surface of the threaded rod 10.

[0041] Brief description of operation: By turning on the motor 9, the threaded rod 10 is rotated, causing the threaded rod 10 to engage with the threaded sleeve 11, which in turn causes the push plate 12 to slide on top of the filter screen 13. When cooling water enters the interior of the distribution box 1, it is filtered through the filter screen 13, causing workpiece debris inside to be filtered onto the filter screen 13. Then, by sliding the push plate 12 back and forth on top of the filter screen 13, the filtered workpiece debris can be pushed into the collection groove 14 for storage.
