[0029] This type of oil-cooled lead screw structure has a motor and other drive equipment installed in the mounting base 4, and the output end connected to the lead screw body 3 to drive the lead screw body 3 to rotate. The bearing cover 8 and the spacer ring 6 block the bearing in the bearing seat 2 to prevent the bearing from shifting. The locking nut 7 blocks the spacer ring 6 to prevent the spacer ring 6 from moving.

[0030] exist Figures 1-3 In the process, the cooling assembly 5 includes an oil-cooled fixing block 501 provided on the outside of the lead screw body 3 for supporting the lead screw body 3. The oil-cooled fixing block 501 is connected to the upper surface of the base 1, and a diverter block 502 for connecting an oil pipe is connected to one side of the oil-cooled fixing block 501. A sealing bearing a503 for sealing is also connected to the inner wall of the oil-cooled fixing block 501. The sealing bearing a503 is connected to the outside of the lead screw body 3.

[0031] This type of lead screw oil cooling structure, with sealed bearing a503, prevents cooling oil from overflowing from the gap between the lead screw body 3 and the oil cooling fixing block 501 when the lead screw body 3 rotates.

[0032] exist Figure 1 and Figure 5 In the middle, the lead screw body 3 has an oil cavity 504 for oil to pass through, and a guide pipe 505 for oil injection is placed in the oil cavity 504. A sealing bearing b506 for sealing is connected to the outside of the guide pipe 505. The sealing bearing b506 is connected to the inner wall of the flow divider block 502.

[0033] This type of screw oil-cooled structure uses a sealed bearing b506 to prevent cooling oil from overflowing from the gap between the guide pipe 505 and the distributor block 502.

[0034] exist Figure 7 In the middle, a bracket 507 for limiting the guide tube 505 is connected to the outside of the guide tube 505. An internal hex bolt 508 for fixing the bracket 507 is connected through the bracket 507. The internal hex bolt 508 is threaded to one side of the lead screw body 3.

[0035] In this type of oil-cooled screw structure, the bracket 507 and the internal hex bolt 508 install the guide tube 505 in the oil chamber 504, allowing the guide tube 505 and the screw body 3 to rotate together, and at the same time, the guide tube 505 can be pulled out from the oil chamber 504.

The piston 510 abuts against the inner wall of the oil chamber 504 and is made of rubber material.

[0037] In this type of lead screw oil cooling structure, the cooling oil in the guide tube 505 is discharged from the through hole 509 and enters the oil chamber 504 to absorb the heat on the lead screw body 3 and cool the lead screw body 3. When the guide tube 505 is pulled out of the oil chamber 504, it drives the piston 510 to scrape out the cooling oil in the oil chamber 504. When impurities in the cooling oil adhere to the inner wall of the oil chamber 504, it can help clean them. When the piston 510 is put into the oil chamber 504, it is first placed in cold water to shrink before being put into the oil chamber 504 to prevent the air in the oil chamber 504 from being compressed during assembly.

[0038] exist Figure 6 and Figure 8 In the middle, the outer side of the guide pipe 505 is connected to a spiral strip 511 for guiding oil flow, and the spiral strip 511 abuts against the inner wall of the oil cavity 504.

[0039] In this type of lead screw oil cooling structure, the spiral 511 connects the guide pipe 505 to the lead screw body 3, improving the strength of the lead screw body 3, while allowing the cooling oil in the oil chamber 504 to flow out along the channels separated by the spiral 511, so as to uniformly cool the lead screw body 3.

[0040] exist Figure 1 In the middle, an oil outlet 512 for oil discharge is provided on the upper part of the inner wall of the diverter block 502, and an oil inlet 513 for oil injection is provided on one side of the inner wall of the diverter block 502.

[0041] This type of screw oil cooling structure involves injecting cooling oil into the oil inlet 513, allowing the cooling oil to enter the guide pipe 505, exit through the through hole 509, then enter the distributor block 502 from the oil chamber 504, and exit from the oil outlet 512.

[0042] In summary: When using this type of screw oil cooling structure, firstly, the oil outlet pipe of the oil cooler is connected to the oil inlet 513, and the oil inlet pipe is connected to the oil outlet 512. After the oil cooler cools the cooling oil, it is injected into the guide pipe 505 through the oil inlet 513, flows out through the through hole 509, enters the oil chamber 504, and carries away the heat from the screw body 3. It flows into the diverter block 502 from the oil chamber 504 along the channel separated by the spiral bar 511, and then returns to the oil cooler from the oil outlet 512. After filtering the cooling oil, it is cooled again and then injected into the guide pipe 505, continuously circulating.
