[0005] The workbench has a positioning seat on one side and a linear drive device on the other side.
[0006] A support tube seat is positioned on the positioning seat. Its surface extends inward at an inward angle to form a discharge hole corresponding to the milling cutter of the milling machine and the oblique hole of the tubular workpiece. The inner side of the discharge hole is connected to the first discharge cavity in the center of the support tube seat. The positioning seat is provided with a flow channel and a fan that connect to the first discharge cavity.
[0007] The feed seat is driven by the linear drive device to move toward the positioning seat. The support tube seat is inserted into the second discharge chamber of the feed seat. The feed seat is provided with a collection box at the outlet end of the second discharge chamber.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a milling machine fixture capable of continuously drilling inclined holes, comprising:
[0032] The workbench 1 has a positioning seat 2 on one side and a linear drive device 3 on the other side.
[0033] The support tube seat 4 is positioned on the positioning seat 2. Its surface extends inward at an inward angle to the discharge hole 5 corresponding to the milling cutter of the milling machine and the inclined hole 110 of the tubular workpiece 100. The inner side of the discharge hole 5 is connected to the first discharge cavity 6 in the center of the support tube seat 4. The positioning seat 2 is provided with a flow channel and a fan 7 that connect the first discharge cavity 6.
[0034] The feed seat 8 is driven by the linear drive device 3 to move toward the positioning seat 2. The support tube seat 4 is inserted into the second discharge chamber 9 of the feed seat 8. The feed seat 8 is provided with a collection box 10 at the outlet end of the second discharge chamber 9.
[0035] The tubular workpiece 100 is sleeved on the support tube seat 4, and the side of the feed seat 8 abuts against the end face of the tubular workpiece 100.
[0036] The linear drive device 3 is a linear motor, and the feed seat 8 is slidably mounted on the linear drive device 3.
[0037] The outer surface of the support tube seat 4 and / or the side of the feed seat 8 are provided with protruding ribs that insert into the groove 120 of the inner wall of the tubular workpiece 100 for circumferential positioning, so as to prevent the tubular workpiece 100 from rotating and shifting when sliding along the support tube seat 4, which would cause the drilling position to be misaligned.
[0038] The support tube base 4 is provided with a plurality of pin holes 11 at intervals on the rear side of the discharge hole 5. The pin holes 11 are connected to the outer surface of the support tube base 4 and the first discharge cavity 6. A floating pin 12 is slidably disposed in the pin holes 11.
[0039] like Figure 4 As shown, the flange on the surface of the floating pin 12 is slidably connected to the guide groove in the pin hole 11. An elastic element is provided between the flange and the guide groove to ensure that the floating pin 12 automatically retracts into the support tube seat 4 when the fan 7 stops running, so as to avoid interference with the sliding of the tubular workpiece 100.
[0040] A baffle plate 13 is provided on the collection box 10 facing the outlet end of the second discharge chamber 9 to block the drilling waste blown out of the second discharge chamber 9 and guide it into the collection box 10, so as to ensure that the waste is completely collected.
[0041] The working principle of a milling machine fixture capable of continuously drilling oblique holes in this embodiment includes: In use, the tubular workpiece 100 is first placed on the end of the support tube seat 4; the linear drive device 3 drives the feed seat 8 to move toward the positioning seat 2, the support tube seat 4 is inserted into the second discharge cavity 9, the feed seat 8 abuts against one end face of the tubular workpiece 100 and pushes it along the support tube seat 4 a set distance, the first oblique hole 110 of the tubular workpiece 100 is aligned with the discharge hole 5, during which the fan 7 runs and high-pressure airflow is introduced into the first discharge cavity 6 to clean the inner cavity of the above structure, the floating pin 12 is pushed out, and the floating pin 12 at the very end abuts against the other end face of the tubular workpiece 100 to achieve positioning, and then the tubular workpiece 100 can be drilled by the milling cutter to form an oblique hole 110 on its side, and the waste material generated by drilling is blown into the second discharge cavity 9 by the airflow and collected in the collection box 10;
[0042] After a single oblique hole is formed, the blower 7 stops running, and the floating pin 12 resets and retracts into the support tube seat 4 under the elastic force of the elastic element. The feed seat 8 continues to move and aligns the second oblique hole 110 of the tubular workpiece 100 with the discharge hole 5. During this process, the blower 7 runs, and the floating pin 12 is pushed out again to achieve positioning, allowing the drilling of the next oblique hole to proceed. By repeating the above operation, continuous drilling of oblique holes in the oil valve assembly can be achieved. After all machining is completed, the feed seat 8 resets, the blower 7 stops running, and the tubular workpiece 100 can be removed from the support tube seat 4 for continuous drilling of the next tubular workpiece 100.
[0043] In summary, due to the adoption of the above technical solution, the milling machine fixture capable of continuously drilling inclined holes in this embodiment has the following advantages compared with the prior art:
[0044] This utility model's milling machine fixture is used for positioning during drilling of oil valve components. A support tube seat provides inner support for the tubular workpiece, while the feed seat pushes the workpiece to align different drilling areas with the discharge hole. After the milling cutter drills the inclined hole, the waste material is blown into a collection box by a high-pressure airflow generated by a blower through the first discharge chamber for unified recycling. This achieves continuous inclined hole drilling and thorough waste material recovery, improving processing efficiency. The floating pin on the support tube seat ensures precise positioning of the tubular workpiece, guaranteeing accurate alignment of the inclined hole and the discharge hole, thus improving drilling accuracy.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
