[0027] The moving device includes a drive motor 41 located on the rear side of the upper surface of the saddle body 3; the motor shaft of the drive motor 41 is connected to a screw 42 via a coupling; a bearing seat matching the front end of the screw 42 is provided on the front side of the upper surface of the saddle body 3; a screw seat is provided at the center of the lower surface of the slide plate 6; the screw seat is provided with a screw hole for screwing into the screw.

[0028] The method of using this utility model is as follows:

[0029] The slide plate 6 is directly mounted on the upper surface of the saddle body 3, and then the turret 2 is directly mounted on the upper surface of the slide plate 6. This structural design eliminates the need for a backing plate. With the backing plate removed, it effectively prevents elastic deformation caused by insufficient rigidity of the material during lathe machining due to the cutting force. It also prevents excessive thickness of the backing plate from amplifying the bending moment of the cutting force on the saddle body 3, and avoids gaps caused by uneven mounting surfaces of the backing plate. This effectively ensures the stability of the tool on the turret 2 when machining the workpiece, and prevents tool position displacement due to the presence of the backing plate, thus ensuring machining accuracy. The saddle body 3, composed of a base plate 301, an inclined part 302, and a support part 303, forms a triangular structure, further ensuring stability during machining. At the same time, the lubrication structure effectively lubricates the gap between the Y-axis slider 8 and the Y-axis guide rail 7, preventing wear between the Y-axis slider 8 and the Y-axis guide rail 7 from causing the slide plate 6 to shift, which in turn causes the tool position on the turret 2 to shift.

[0030] When the tool on the turret 2 needs to move in the Y-axis direction, simply turn on the drive motor 41. The motor shaft of the drive motor 41 will drive the screw 42 to rotate. The screw 42 is screwed into the screw hole of the screw seat. The cooperation between the Y-axis guide rail 7 and the Y-axis slider 8 restricts the slide plate 6 to move only along the Y-axis direction. Therefore, when the screw 42 rotates, the slide plate 6 can convert the rotational force into its own force to move along the Y-axis, thereby realizing the movement of the tool on the turret 2.

[0031] A number of support plates 304 are evenly distributed from front to back between the lower surface of the inclined part 302 and the upper surface of the support part 303. The inclination of the support part 303 can provide support and effectively improve the rigidity of the saddle body 3, further ensuring the stability of the tool on the turret 2 during machining.

[0032] When lubrication is needed on the gap between the Y-axis guide rail 7 and the Y-axis slider 8, the inner rod 38 can be pushed by the pressure head 39, causing the inner rod 38 to push the extrusion piston 17 towards the oil inlet 11. At this time, the grease filling the oil reservoir 15 will be squeezed out and pressurized towards the opening and closing head 28 through the opening and closing hole 16. As the opening and closing head 28 is pushed towards the oil inlet 11, the spring 30 is compressed and generates elastic force, and the opening and closing hole 16 is no longer blocked and sealed by the opening and closing head 28. The grease will then enter the receiving groove from the opening and closing hole 16. The grease enters the movable groove 20 through several oil inlets 25. Under the push of the subsequent grease, the grease enters the oil guide groove 9 of the Y-axis slider 8 through the oil inlet 21 and eventually fills the oil guide groove 9. As the Y-axis slider 8 moves along the trajectory of the Y-axis guide rail 7, the grease seeps out from the oil guide groove 9 and fills the gap between the Y-axis slider 8 and the Y-axis guide rail 7, which plays an effective lubricating role and effectively avoids the situation where the Y-axis slider 8 and the Y-axis guide rail 7 wear each other due to long-term contact, thus playing an anti-wear role.

[0033] After lubrication is complete, stop pushing the extrusion piston 17. At this time, the opening and closing head 28 will block and seal the opening and closing hole 16 again under the action of the spring 30 to avoid wasting grease. If the extrusion piston 17 is difficult to push due to the short length of the outer tube 33 during lubrication, the length of the outer tube can be extended. At this time, simply pull the inner rod 38 away from the oil inlet 11 by the pressure head 39. Finally, the end of the inner rod 38 with the external thread 40 will move to the position of the connecting part 36. Then, the end of the inner rod 38 will be screwed into the connecting part 36 by rotating the inner rod 38 to complete the fixation between the two. Since the outer tube 33 has positioning wings 35 on the upper and lower sides of the outer wall that match the positioning groove 34, the outer tube 33 will remain fixed when the inner rod 38 rotates under the restriction of the positioning groove 34, thereby ensuring that the end of the inner rod 38 is smoothly screwed into the connecting part 36, effectively extending the actual length of the outer tube 33, so that the extrusion piston 17 can move a larger stroke, which is convenient for fully extruding the grease.
