[0037] The work table 2 is installed with the drive mechanism 4 of the action of sliding rail 23 in through -hole 21, and it is used for making sliding rail 23 slide on work table 2, and the top of sliding rail 23 is horizontally slidably installed with displacement block 24, and the electromagnetic sliding block 25 of sliding rail 23 is fixedly installed with displacement block 24 is connected, and the top of displacement block 24 is fixed with the telescopic rod 26 of vertical, and the top of two telescopic rods 26 is fixed with the connecting block 27, and the top of displacement block 24 is fixedly installed with the electric cylinder 241 of connecting block 27 is connected, and the bottom of the open shape of installation cover 5 is fixedly installed on the side close to positioning frame 22 of connecting block 27, and the installation shaft 51 of horizontal is rotatably installed on installation cover 5, and the open wire drill bit 52 is detachably fixedly installed on the side close to positioning frame 22 of installation shaft 51, and it is worth mentioning that: detachable installation mode between open wire drill bit 52 and installation shaft 51 is prior art structure, belongs to the known technology of the person skilled in the art, and here is not repeated, and one end of installation shaft 51 extends into installation cover 5, and the motor one 53 for driving installation shaft 51 to rotate is fixedly installed in installation cover 5.

[0038] The work table 2 is installed with the drive mechanism 4 of the action of sliding rail 23 in through -hole 21, and it is used for making sliding rail 23 slide on work table 2, and the top of sliding rail 23 is horizontally slidably installed with displacement block 24, and the electromagnetic sliding block 25 of sliding rail 23 is fixedly installed with displacement block 24 is connected, and the top of displacement block 24 is fixed with the telescopic rod 26 of vertical, and the top of two telescopic rods 26 is fixed with the connecting block 27, and the top of displacement block 24 is fixedly installed with the electric cylinder 241 of connecting block 27 is connected, and the bottom of the open shape of installation cover 5 is fixedly installed on the side close to positioning frame 22 of connecting block 27, and the installation shaft 51 of horizontal is rotatably installed on installation cover 5, and the open wire drill bit 52 is detachably fixedly installed on the side close to positioning frame 22 of installation shaft 51, and it is worth mentioning that: detachable installation mode between open wire drill bit 52 and installation shaft 51 is prior art structure, belongs to the known technology of the person skilled in the art, and here is not repeated, and one end of installation shaft 51 extends into installation cover 5, and the motor one 53 for driving installation shaft 51 to rotate is fixedly installed in installation cover 5.

[0039] By setting a limiting mechanism 6, when the threaded hole is made in the electric actuator housing, the electric actuator housing is fitted onto the outside of the positioning mechanism 3 through the mounting hole. The positioning mechanism 3 pre-positions the electric actuator housing, allowing it to rotate only outside the positioning mechanism 3 and preventing horizontal displacement. At this time, the limiting mechanism 6 limits the electric actuator housing, ensuring that the end face of the electric actuator housing near the through hole 21 is perpendicular to the axis of the mounting shaft 51. This replaces the previous method of manual measurement of the electric actuator housing's position using a right-angle ruler, ensuring that the end face of the electric actuator housing is perpendicular to the axis of the mounting shaft 51. The method of perpendicularity of axis 1 makes operation simple, thereby reducing the difficulty of positioning the electric actuator housing and improving the drilling efficiency of threaded holes on the electric actuator housing. After the electric actuator housing is positioned, the slide rail 23 is moved closer to the positioning frame 22 by the drive mechanism 4. At this time, the screw drill bit 52 is brought into contact with the opening of the electric actuator housing by the cooperation of the electric cylinder 241 and the electromagnetic slider 25. Then, the motor 53 is controlled to rotate the mounting shaft 51 on the mounting cover 5. With the cooperation of the drive mechanism 4, the slide rail 23 is moved closer to the positioning frame 22, thus realizing the effect of drilling threaded holes on the electric actuator housing.

[0040] Example 2

[0041] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0042] In this embodiment, the limiting mechanism 6 includes a limiting plate 61 that is slidably mounted on the top of the workbench 2 along the direction of the positioning frame 22. The side of the limiting plate 61 near the positioning frame 22 is perpendicular to the axial direction of the mounting shaft 51. A horizontally oriented driving rod 62 is rotatably mounted on the workbench 2. The driving rod 62 is threadedly connected to the limiting plate 61. In use, the electric actuator housing is sleeved on the outside of the positioning mechanism 3. After the electric actuator housing is pre-positioned by the positioning mechanism 3, the driving rod 62 is rotated to make the limiting plate 61 slide towards the positioning frame 22, so that the side of the limiting plate 61 near the positioning frame 22 is in contact with the end face of the electric actuator housing. This makes the end face of the electric actuator housing near the through hole 21 perpendicular to the axial direction of the mounting shaft 51, which is simple to operate.

[0043] In this embodiment, the driving mechanism 4 includes a threaded rod 41 that is horizontally rotatably mounted on the worktable 2. The threaded rod 41 is threadedly connected to the slide rail 23. A second motor 42 for driving the threaded rod 41 to rotate is fixedly mounted on the worktable 2. In use, the second motor 42 is turned on and works, thereby driving the threaded rod 41 to rotate on the worktable 2, thereby allowing the slide rail 23 to slide on the worktable 2.

[0044] In this embodiment, the positioning mechanism 3 includes a positioning rod 31, a guide rod 32, a positioning plate 33, a sliding block 34, a hinge rod 35, and an electric push rod 36;

[0045] A positioning rod 31 is fixedly installed at the end of the column 221. A mounting cavity 311 is formed on the positioning rod 31. Guide rods 32 are symmetrically and movably inserted through the positioning rod 31 on one side of the mounting cavity 311. Positioning plates 33 are fixedly installed at the ends of the two guide rods 32 that are far apart from each other. Sliding blocks 34 are slidably installed on the positioning rods 31 within the mounting cavity 311. Hinges 35 are symmetrically hinged to the sliding blocks 34. The other ends of the two hinges 35 are respectively hinged to the two positioning plates 33. An electric actuator 36, fixedly connected to the sliding block 34, is fixedly installed within the mounting cavity 311 for electric actuation. When positioning the actuator housing, the electric actuator housing is fitted onto the outside of the positioning rod 31 through the mounting hole. The electric push rod 36 is controlled to make the sliding block 34 slide on the positioning rod 31. Both hinge rods 35 rotate around their own hinge points on the sliding block 34. The other ends of the two hinge rods 35 rotate between the two positioning plates 33, respectively. This allows the two positioning plates 33 to slide away from each other along the two guide rods 32, so that both positioning plates 33 abut against the inner sidewall of the mounting hole of the electric actuator housing. This achieves the positioning effect of the electric actuator housing body, and the operation is simple.

[0046] In this embodiment, a protective shell 7 is fixedly installed on the slide rail 23 and sleeved on the outside of the mounting cover 5. It is worth noting that the protective shell 7 extends to the outside of the threaded drill bit 52 on the side near the positioning frame 22. The side of the protective shell 7 near the positioning frame 22 and its bottom are both open. The inner walls on both sides of the protective shell 7 are located on the same vertical plane as the inner walls on both sides of the through hole 21. By setting the protective shell 7, when the threaded hole is opened in the electric actuator housing by the threaded drill bit 52, the protective shell 7 extends to the outside of the electric actuator housing. Thus, when the debris generated during the threading of the electric actuator housing is splashed outward, when the debris comes into contact with the protective shell 7, it can fall into the through hole 21 through the bottom opening of the protective shell 7, effectively avoiding the situation where the debris splashes outward and causes physical injury to the workers.
