[0041] Please see Figure 1-8 As shown, this embodiment of the present invention provides a spindle sliding platform, which includes a horizontal sliding assembly 1, a spindle assembly 2, and a rotary drive assembly 3, wherein:

[0042] The horizontal sliding assembly 1 serves as the mounting base for the spindle sliding platform, allowing the entire spindle assembly to move horizontally to ensure precise and smooth movement. The spindle assembly 2 includes a spindle seat 21, a rotary table 22, a rotary chuck 23, and a rotary clamp 24. The spindle seat 21, as the fixed part of the spindle assembly, is mounted on the horizontal sliding assembly and provides support for the rotary table 22, rotary chuck 23, and rotary clamp 24. The spindle seat 21 is mounted on the horizontal sliding assembly 1, and the rotary table 22 is rotatably connected to the spindle seat 21, allowing the spindle assembly to rotate around its vertical axis, increasing machining flexibility. The rotary chuck 23 is connected to the end of the rotary table 22 furthest from the spindle seat 21, and the rotary clamp 24 is coaxially inserted into the end of the rotary chuck 23 furthest from the rotary table 22.

[0043] The rotary drive assembly 3 is used to drive the rotation of the rotary table 22, the rotary chuck 23 and the rotary clamp 24. In this embodiment, the rotary drive assembly 3 is installed on one side of the spindle seat 21 and is adapted to be connected to the rotary table 22 to drive the rotary table 22, the rotary chuck 23 and the rotary clamp 24 to rotate.

[0044] Thus, the horizontal sliding assembly 1 allows the spindle assembly to move precisely to different positions on the workpiece in the horizontal direction, while the rotational capabilities of the rotary table 22 and rotary chuck 23 allow the spindle to approach and process the workpiece from multiple angles. The rotary drive assembly 3 enables the spindle assembly to quickly change direction, improving machining flexibility and efficiency, and allowing for the machining of complex shapes while reducing workpiece repositioning and clamping time. The design of the rotary fixture 24 ensures the stability of the workpiece during machining.

[0045] For further details, please refer to Figure 1 , 4As shown in Figure 5, the horizontal sliding assembly 1 includes a rotating chuck base plate 11, two slide rail components 12, and a cylinder drive component 13. The rotating chuck base plate 11 is installed at the bottom of the spindle seat 21. The two slide rail components 12 are horizontally parallel to each other on both sides of the bottom of the rotating chuck base plate 11. The cylinder drive component 13 is located between the two slide rail components 12 and is also located below the spindle seat 21. One side of the cylinder drive component 13 is connected to one end of the rotating chuck base plate 11, and the other side is connected to the other end of the rotating chuck base plate 11.

[0046] In this embodiment, the fixed portion of the horizontal sliding assembly 1 of the rotary chuck base plate 11 is installed at the bottom of the spindle seat 21, providing a stable mounting platform for the slide rail assembly 12 and the cylinder drive assembly 13. Two slide rail assemblies 12 are horizontally parallel to each other on both sides of the bottom of the rotary chuck base plate 11, providing guidance and support for the cylinder drive assembly 13. The slide rail assemblies 12 are made of high-strength material to withstand the forces generated by the cylinder drive assembly 13 during movement.

[0047] For further details, please refer to Figure 5 As shown, each slide rail component 12 includes several sliders 121 and slide bars 122 connected to the bottom of the spindle seat 21, and the sliders 121 are adapted to be slidably connected to the slide bars 122, which are connected to the overall base. Thus, the sliding connection between the sliders 121 and the slide bars 122 allows the spindle seat 21 to move precisely along a predetermined path, and this precise sliding is crucial for achieving accurate machining positions.

[0048] For further details, please refer to Figure 5 As shown, the cylinder drive component 13 includes a cylinder rear flange connecting plate 131, a first cylinder 132, and a translation block 133. The cylinder rear flange connecting plate 131 is vertically connected to one side of the slide bar 122. The first cylinder 132 is located in the middle of the two slide bars 122. The translation block 133 is installed at the front end of the first cylinder 132. The cylinder rear flange connecting plate 131 and the translation block 133 are respectively located at both ends of the first cylinder 132. The cylinder rear flange connecting plate 131 is connected to the rear end face of the first cylinder 132. One side of the translation block 133 is sleeved on the output shaft of the first cylinder 132, and the other side is connected to the end face of the rotating chuck base plate 11.

[0049] Therefore, the configuration of the cylinder rear flange connecting plate 131 and the first cylinder 132 ensures that the force of the cylinder can be effectively transmitted to the translation stop 133. This design allows the linear motion of the cylinder to be directly converted into the translational motion of the spindle seat 21. Precise control of the first cylinder 132 enables precise positioning of the spindle seat 21. By adjusting the air pressure of the cylinder, the moving speed and distance of the translation stop 133 can be controlled, thereby achieving precise positioning. The vertical connection between the cylinder rear flange connecting plate 131 and the slide bar 122 provides stability, ensuring that the entire system remains stable when the cylinder drive components are working.

[0050] For further details, please refer to Figure 4 As shown, the horizontal sliding assembly 1 also includes limiting components 14 disposed on both sides of the rotary chuck base plate 11. The limiting components 14 include a first limiting structure 141 and a second limiting structure 142. The first limiting structure 141 is installed on the side of the rotary chuck base plate 11 away from the rotary clamp 24, and the second limiting structure 142 is connected between the rotary chuck base plate 11 and the cylinder rear flange connecting plate 131.

[0051] Therefore, by setting the first limiting structure 141 and the second limiting structure 142, the limiting component 14 ensures that the movement of the spindle seat 21 on the slide rail component 12 will not exceed the safe range, thereby improving the safety of the entire system.

[0052] For further details, please refer to Figure 1 , 6 As shown, the rotary drive assembly 3 includes a servo motor 31, a motor mount 32, a first synchronous pulley 33, a second synchronous pulley 34, and a belt 35.

[0053] The servo motor 31 is arranged parallel to the rotation center axis of the rotary table 22. The motor base 32 is installed on one side of the spindle base 21. The first synchronous pulley 33 is connected to the output shaft of the servo motor 31. The second synchronous pulley 34 is installed on the rotary table 22. The belt 35 is sleeved between the first synchronous pulley 33 and the second synchronous pulley 34. The servo motor 31 is adapted to be installed on the motor base 32 and the output shaft of the servo motor 31 passes through the motor base 32. The rotary table 22 passes through the spindle base 21 and is connected to the second synchronous pulley 34 so that the first synchronous pulley 33 and the second synchronous pulley 34 are located in the same vertical plane.

[0054] The design of the rotary drive assembly 3, through the coordinated work of the servo motor 31, synchronous pulley and belt 35, provides a precise, efficient and compact power transmission method, improving the flexibility and precision of the processing equipment.

[0055] For further details, please refer to Figure 4As shown, the first limiting structure 141 includes a first limiting block 1411 located on the side of the slide bar 122 away from the rear flange connecting plate 131 of the cylinder and a first limiting wheel 1412 connected to the first limiting block 1411. The first limiting wheel 1412 is adapted to abut against the end face of the rotating chuck base plate 11.

[0056] For further details, please refer to Figure 4 As shown, the second limiting structure 142 includes a second limiting block 1421 arranged in an L-shape and a connecting screw 1422. A limiting groove 14211 is opened on the horizontal plate of the second limiting block 1421 along the sliding direction of the slide bar 122. A limiting bolt 14212 is vertically inserted in the limiting groove 14211 and is threaded to the top surface of the cylinder rear flange connecting plate 131. The connecting screw 1422 is horizontally inserted on the vertical plate of the second limiting block 1421 and is connected to the side end face of the cylinder rear flange connecting plate 131.

[0057] For further details, please refer to Figure 1 , 8 As shown, it also includes a belt tensioning assembly 4, which includes an idler tensioning block 41 and an idler plate 42 connected to the motor base 32, and an idler 43 rotatably mounted in the idler plate 42. The idler 43 is adapted to press against the outer surface of the belt 35.

[0058] Therefore, the belt tensioning assembly 4 reduces belt slippage and improves transmission efficiency by maintaining appropriate belt tension.
