[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: As Figures 1-4As shown, a multi-axis, multi-stage motion control mechanism includes a gantry frame 1. A worktable 2 is fixedly connected to the inner wall of the gantry frame 1. Two electric push rods 3 are fixedly connected to the inner wall of the gantry frame 1. A moving block 4 is fixedly connected to the top of each of the two electric push rods 3. A threaded rod 5 is rotatably connected to the side of the moving block 4. The threaded rod 5 is driven by a dual-axis motor, which is fixedly connected to the side of the moving block 4. Multiple detection blocks 6 are threadedly connected to the circumference of the threaded rod 5. A limit rod 7 is fixedly connected to the side of the moving block 4. Under the restriction of the limit rod 7, the detection blocks 6 can only move on the threaded rod 5 and cannot rotate, thus playing a limiting role. The multiple detection blocks 6 pass through... A maintenance device 8 is provided on the top of the gantry frame 1, which is slidably connected to the circumferential surface of the limiting rod 7. The maintenance device 8 includes a slide groove 81, which is opened on the top of the gantry frame 1. Two sliders 82 are slidably connected to the inner wall of the slide groove 81. The bottom of each slider 82 is hinged with an elastic hinge rod 83. The end of the elastic hinge rod 83 away from the slider 82 is fixedly connected to the top of the moving block 4. A connecting rod 84 is fixedly connected to the bottom of the slider 82. A U-shaped frame 85 is fixedly connected to the side of the moving block 4. A slot 86 is opened on the top of the U-shaped frame 85. A small square 87 is slidably connected to the inner wall of the slot 86. The connecting rod 84 is located away from the top of the moving block 4. One end of slider 82 is fixedly connected to the top of small cube 87. A nozzle 88 is fixedly connected to the side of small cube 87. A long groove for moving nozzle 88 is provided on the inner wall of U-shaped frame 85. A liquid storage tank 89 is fixedly connected to the top side of gantry frame 1. A one-way inlet pipe is fixedly connected to the top of liquid storage tank 89 for replenishing lubricating fluid in liquid storage tank 89. A water pipe 810 is fixedly connected to the side of liquid storage tank 89. The end of water pipe 810 away from liquid storage tank 89 is fixedly connected to the top of small cube 87. An L-shaped rod 811 is fixedly connected to the top of slider 82. A pressing element 812 is provided on the side of liquid storage tank 89. The working principle of the pressing component 812 here is similar to that of a spray bottle. The pressing component 812 is composed of a pressing part and a spring pump. The spring pump's elastic force is used to achieve reset. The pressing component 812 is used to control the lubricating liquid in the reservoir 89 to be sprayed out through the nozzle 88. The pressing component 812 is located on the movement trajectory of the L-shaped rod 811. During its movement, the L-shaped rod 811 can contact the pressing component 812 to realize that the lubricating liquid in the reservoir 89 is sprayed out through the nozzle 88. The threaded rod 5 is located on the movement trajectory of the nozzle 88. The nozzle 88 and the threaded rod 5 are located on the same plane, which can ensure that the lubricating liquid sprayed out by the nozzle 88 is sprayed onto the threaded rod 5.

[0026] First, when the device makes a creaking sound, it indicates significant wear between the threaded rod 5 and the detection block 6, requiring lubrication. Activating the electric push rod 3 causes it to move downwards, which in turn moves the slider 82 in the groove 81 under the force of the elastic hinge rod 83. This movement of the slider 82 moves the connecting rod 84 in both directions, which in turn moves the small square 87 in both directions. The movement of the small square 87 in both directions then moves the nozzle 88 in both directions. Simultaneously, the slider 82... The movement of the L-shaped rod 811 causes the L-shaped rod 811 to move. During the movement, the L-shaped rod 811 contacts the pressing element 812. The pressing element 812 controls the lubricant in the reservoir 89 to be sprayed out through the nozzle 88. The lubricant sprayed out by the nozzle 88 covers a layer of oil film on the surface of the threaded rod 5, which plays a role in subsequent maintenance. The dual-axis motor is started. The output shaft of the dual-axis motor drives the movement of the detection block 6. During the movement, the detection block 6 can evenly spread the lubricant on the inner wall of the thread groove of the threaded rod 5, and can also maintain the inside of the detection block 6.

[0027] Example 2: Figures 1-4 As shown, a multi-axis, multi-level motion control mechanism includes a pollution prevention device 9 at the bottom of the moving block 4. The pollution prevention device 9 comprises two fixed blocks 91, the tops of which are fixedly connected to the bottom of the moving block 4. A drip box 92 is slidably connected between the two fixed blocks 91, and a guide rod 93 is fixedly connected to the bottom of the drip box 92. A collection box 94 is fixedly connected to the side of the gantry frame 1 to collect waste liquid and prevent pollution. A rotating shaft 95 is fixedly connected to the output end of a dual-axis motor, and a rotating rod 96 is rotatably connected to the side of the gantry frame 1. A drive shaft 95 is connected between the rotating shaft 95 and the rotating rod 96. The track 97 has a pressure block 98 fixedly connected to its circumferential surface. A C-shaped rod 99 is fixedly connected to the side of the gantry 1. A striking rod 910 slides through the side of the C-shaped rod 99. A spring is provided between the striking rod 910 and the inner wall of the C-shaped rod 99. A guide rod 93 is in contact with the collection box 94. The guide rod 93 is located on the movement trajectory of the striking rod 910. The striking rod 910 is located on the movement trajectory of the pressure block 98. Multiple pressure blocks 98 are provided and are arranged in a linear array on the circumferential surface of the track 97. The multiple design of the pressure blocks 98 increases the striking frequency of the striking rod 910 and enhances the flow efficiency.

[0028] First, the operator slides the drip box 92 below the threaded rod 5 to temporarily store any excess lubricant. Because the drip box 92 is angled, the lubricant slides to the left side of the drip box 92 and flows through the guide rod 93 into the collection box 94, preventing excess waste from causing pollution. Simultaneously, the output shaft of the other end of the dual-axis motor drives the rotating shaft 95 to rotate. The rotation of the rotating shaft 95 drives the rotation of the track 97, which in turn drives the rotating rod 96. The rotation of the track 97 also drives the rotation of the pressure block 98. During its rotation, the pressure block 98 contacts the arc surface of the striking rod 910, causing the striking rod 910 to move to the left. This leftward movement compresses the spring. When the pressure block 98 has completely passed the arc surface of the striking rod 910, the spring returns to its original position through its own elasticity, thus causing the striking rod 910 to return to its original position. The returning striking rod 910 then strikes the guide rod 93, accelerating the collection of lubricant from the drip box 92 into the collection box 94.

[0029] 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.
