The third slide seat 403 is fixed on the third moving frame 401, and the third slide seat 403 is slidably sleeved on the third slide rail 402.

[0032] An oil supply assembly is provided on the fixed frame 1, and the oil supply assembly includes an oil storage box 51, an oil push plate 52, a threaded rod 53 and three connecting pipes 54. The oil storage box 51 is fixed to the side of the fixed frame 1, and an observation window 7 is provided on the side of the oil storage box 51. The oil push plate 52 is slidably installed on the inner surface of the oil storage box 51, and the threaded rod 53 passes through the oil storage box 51, and the threaded rod 53 and the oil storage box 51 are threadedly sleeved. One end of the threaded rod 53 located inside the oil storage box 51 is rotatably installed on the top surface of the oil push plate 52, and a handle is installed on the top of the threaded rod 53. One end of the three connecting pipes 54 is connected to the oil storage box 51. The connecting pipe 54 adopts a telescopic pipe. When the threaded rod 53 rotates, it can drive the oil push plate 52 to move. During the movement, the oil push plate 52 can press the lubricating oil in the oil storage box 51 into the inside of the three cavities 61 through the three connecting pipes 54 respectively;

[0033] The first slide 203, the second slide 302 and the third slide 403 are commonly provided with a lubrication assembly, which includes three cavities 61 and a plurality of oil outlet holes 62. The three cavities 61 are respectively opened inside the first slide 203, the second slide 302 and the third slide 403, and the plurality of oil outlet holes 62 are respectively provided on the first slide 203, the second slide 302 and the third slide 403.

[0034] The specific working principle of the utility model is as follows:

[0035] When the XYZ platform motion mechanism proposed by the utility model is in use, when the first slide rail 202, the second slide rail 303 and the third slide rail 402 need to be lubricated, the staff first makes the first slide seat 203, the second slide seat 302 and the third slide rail 403 slide back and forth on the first slide rail 202, the second slide rail 303 and the third slide rail 402 respectively, and rotates the threaded rod 53 at the same time. When the threaded rod 53 rotates, it can drive the push plate 52 to move. During the movement, the push plate 52 can push the oil in the oil storage box 51 The lubricating oil is pressed into the three cavities 61 through the three connecting pipes 54, and then the oil flows out through the plurality of oil outlet holes 62 after entering the three cavities 61, and flows to the first slide rail 202, the second slide rail 303 and the third slide rail 402 respectively. In addition, the first slide seat 203, the second slide seat 302 and the third slide seat 403 can evenly apply the lubricating oil to the first slide rail 202, the second slide rail 303 and the third slide rail 402 during the reciprocating movement, thereby realizing the function of automatically adding lubricating oil;

[0036] The oil storage box 51 is provided with an observation window 7, through which the staff can observe the remaining amount of lubricating oil in the oil storage box 51, so that the staff can add lubricating oil to the oil storage box 51 in time;

[0037] For the XYZ platform motion mechanism, the X-axis usually moves in the horizontal direction. It is driven by a motor, a lead screw or a synchronous belt and other driving components to drive the platform to perform precise linear motion in the X-axis direction. For example, the rotation of the motor drives the lead screw to rotate, thereby pushing the platform part connected to the lead screw to move along the X-axis. The Y-axis is perpendicular to the X-axis, and linear motion along the Y-axis direction is also achieved through a similar driving mechanism. For example, another motor and a transmission device are used to control the position of the platform on the Y-axis. The Z-axis is mainly responsible for vertical movement. It can drive the lead screw or other lifting mechanism through a motor to achieve the rise or fall of the platform in the Z-axis direction, which enables the platform to Reaching different height positions in three-dimensional space. In actual work, by precisely controlling the movement speed, direction and position of the X, Y and Z axes, various complex motion trajectories of the platform in three-dimensional space can be realized to meet different application requirements, such as material handling in industrial automation, tool positioning in CNC machine tools, and nozzle movement in 3D printing. For example, in a 3D printer, the nozzle is installed on the Z axis, and the printing platform moves in the X and Y axis directions, so that materials are stacked layer by layer according to the preset model to form a three-dimensional object. In industrial robots, by controlling the three-axis mobile platform, objects can be accurately grasped and placed at the specified position.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
