Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of CNC machining equipment, specifically to an integrated structure of a CNC rotary table. Background Technology
[0002] In the field of CNC machining, the CNC rotary table is a crucial component for machining complex parts. Traditional CNC rotary table structures typically employ a design where a rotary axis is mounted on a slide via a housing, as shown in the attached diagram. Figure 1 As shown, the rotary table includes a linear guide rail, a linear slide table, a housing, and a rotary axis. This structure has several problems: First, the assembly process between the housing and the linear slide table, and between the housing and the rotary axis, inevitably introduces errors. These errors accumulate over long-term use, leading to a significant decrease in the positioning accuracy of the rotary table, making it difficult to meet the requirements of high-precision machining. Second, the additional housing increases the overall height of the rotary table, significantly limiting its spatial layout and hindering integration and miniaturization. Third, the multi-layered connection reduces the rigidity of the rotary table, making it prone to vibration during machining, affecting the surface quality of the workpiece, and also reducing the stability and service life of the equipment. Therefore, developing an integrated CNC rotary table structure that can eliminate assembly errors, reduce overall height, and enhance rigidity has become an urgent technical problem to be solved in this field. Utility Model Content
[0003] The purpose of this utility model is to provide an integrated structure for CNC rotary tables. By optimizing and innovatively designing the linear guide rail, linear slide table, and rotary axis table, it eliminates assembly errors in traditional structures, reduces the overall height of the rotary table, and improves structural rigidity, thereby enhancing the machining accuracy, stability, and service life of the CNC rotary table to meet the demands of modern CNC machining for high precision and high efficiency.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an integrated structure for a CNC rotary table, comprising a linear slide rail, a linear slide table, and a rotary axis table;
[0005] The linear slide rail extends along a preset direction, and its two side walls are provided with parallel slide rail grooves.
[0006] The bottom of the linear slide table is symmetrically provided with sliders that are adapted to the linear slide rail. The sliders are embedded in the slide rail groove to realize the linear movement of the linear slide table along the linear slide rail.
[0007] The linear slide has a circular groove in the middle, and the bottom of the circular groove has a number of positioning holes for mounting the rotary shaft table. The positioning holes are arranged in a ring array.
[0008] The bottom of the rotating shaft platform is provided with a positioning post corresponding to the positioning hole. The rotating shaft platform is installed in the circular groove through the cooperation of the positioning post and the positioning hole, and the outer peripheral wall of the rotating shaft platform is in close contact with the inner wall of the circular groove.
[0009] In a preferred embodiment, a rolling element is provided between the slider and the linear guide rail.
[0010] In a preferred embodiment, the rolling element is a ball or a roller.
[0011] In a preferred embodiment, an annular sealing ring is further provided between the outer peripheral wall of the rotating shaft platform and the inner wall of the circular groove.
[0012] In a preferred embodiment, the linear slide rail is further provided with mounting through holes for fixing.
[0013] In a preferred embodiment, an elastic buffer layer is provided between the positioning post and the positioning hole to mitigate the impact force during the installation of the rotary table.
[0014] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:
[0015] This application discloses an integrated CNC rotary table structure. By eliminating the outer shell of the rotary axis table and directly installing it within the circular groove of the linear slide, it eliminates assembly errors between the outer shell and the slide, and between the outer shell and the rotary axis table, significantly improving the positioning accuracy of the rotary table and meeting the requirements of high-precision CNC machining. Eliminating the outer shell makes the entire integrated CNC rotary table structure more compact, reducing the overall height of the rotary table, saving installation space, facilitating equipment integration and miniaturization, and improving the flexibility of spatial layout. The direct and tight fit between the rotary axis table and the linear slide enhances the connection rigidity between them, reduces structural vibration and deformation, and improves the stability of the rotary table during machining, thereby improving the surface quality of the workpiece and the service life of the equipment. The rolling element between the slider and the linear guide reduces motion resistance and improves the motion accuracy and efficiency of the linear slide. The elastic buffer layer alleviates installation impact and running vibration, further improving the overall performance of the rotary table. The annular sealing ring effectively prevents foreign matter from entering the rotary table, protecting the core components and improving the reliability and service life of the rotary table.

[0026] Example 1
[0027] Appendix Figure 2 The integrated structure of the CNC rotary table described in this utility model includes a linear slide rail 1, a linear slide table 2, and a rotary axis table 3;
[0028] The linear slide rail 1 extends along a preset direction, and its two side walls are provided with parallel slide rail grooves 4; the design of the slide rail grooves 4 provides precise guidance for the movement of the linear slide table 2, ensuring the stability and straightness of the linear slide table 2 during the movement.
[0029] The bottom of the linear slide table 2 is symmetrically provided with sliders 5 that are adapted to the linear slide rail 1. The sliders 5 are embedded in the slide rail groove 4 to realize the linear slide table 2 moving linearly along the linear slide rail 1. This structural design makes the movement of the linear slide table 2 more stable and smooth, and can effectively reduce friction and wear during the movement.
[0030] The linear slide 2 has a circular groove 6 in the middle, and the bottom of the circular groove 6 has a plurality of positioning holes for installing the rotary shaft 3. The positioning holes are arranged in a ring array. The ring array of positioning holes can ensure the accuracy and stability of the installation of the rotary shaft 3, so that the rotary shaft 3 can be evenly stressed during operation, and improve the reliability of the overall structure.
[0031] The bottom of the rotary table 3 is provided with a positioning post corresponding to the positioning hole. The rotary table 3 is installed in the circular groove 6 through the cooperation of the positioning post and the positioning hole, and the outer peripheral wall of the rotary table 3 is tightly fitted with the inner wall of the circular groove 6. This direct installation method eliminates the outer shell component in the traditional structure, which not only reduces the assembly steps and eliminates the error caused by the assembly of the outer shell, but also reduces the overall height of the turntable, while enhancing the connection rigidity between the rotary table 3 and the linear slide 2.
[0032] To further optimize the structure, a rolling element is provided between the slider 5 and the linear slide rail 1. The rolling element converts the sliding friction between the slider 5 and the linear slide rail 1 into rolling friction, which greatly reduces the motion resistance, improves the motion accuracy and efficiency of the linear slide table 2, and also reduces the wear of components and extends the service life of the equipment.
[0033] To further optimize the structure, the rolling element is a ball or a roller; balls and rollers are common rolling elements, which have good wear resistance and rolling performance, and can stably realize the rolling friction between the slider 5 and the linear slide rail 1, ensuring the smooth operation of the linear slide table 2.
[0034] To further optimize the structure, an annular sealing ring 7 is provided between the outer peripheral wall of the rotary shaft 3 and the inner wall of the circular groove 6. The annular sealing ring 7 can effectively seal the gap between the rotary shaft 3 and the inner wall of the circular groove 6, preventing chips, coolant and other debris generated during the processing from entering the turntable, avoiding damage to the turntable components, and further improving the reliability and service life of the turntable.
[0035] To further optimize the structure, the linear slide rail 1 is also provided with mounting through holes 8 for fixing. The mounting through holes facilitate the connection and fixing of the linear slide rail 1 with other equipment or bases, so that the entire integrated structure of the CNC rotary table can be more stably installed in the required working position, ensuring the stability of the rotary table during operation.
[0036] To further optimize the structure, an elastic buffer layer is provided between the positioning column and the positioning hole to alleviate the impact force during the installation of the rotary table 3. The presence of the elastic buffer layer can effectively alleviate the impact force during the installation of the rotary table 3, reduce damage to the components during the installation process, and absorb and buffer the vibration generated by the movement during the operation of the turntable, further improving the stability and reliability of the turntable.
[0037] When installing this integrated CNC rotary table structure, firstly, fix the linear guide rail 1 on the base of the CNC machining equipment; according to the design requirements and installation position of the equipment, use bolts, nuts and other connecting parts to firmly fix the linear guide rail 1 to the base through the mounting through holes 8 on the linear guide rail 1, ensuring that the installation position of the linear guide rail 1 is accurate and stable, and extends along the preset direction.
[0038] Next, install slider 5 onto the bottom of linear slide table 2, aligning slider 5 with the mounting position on the bottom of linear slide table 2. Install slider 5 onto linear slide table 2 using an appropriate method (such as press-fitting), ensuring that slider 5 is firmly connected to linear slide table 2. Then, install linear slide table 2 with slider 5 onto linear slide rail 1, so that slider 5 is embedded in the slide rail grooves 4 on both sides of linear slide rail 1. During installation, ensure that slider 5 and the guide structure (if any) in the slide rail groove 4 are correctly matched to ensure that linear slide table 2 can move smoothly in a straight line along linear slide rail 1. At the same time, rolling elements (balls or rollers) can be installed between slider 5 and linear slide rail 1 as needed, and an appropriate amount of grease can be added to further reduce motion resistance and improve the motion performance of linear slide table 2.
[0039] When installing the rotary shaft stage 3, first apply an appropriate amount of installation adhesive (if needed) to the positioning hole at the bottom of the circular groove 6 in the middle of the linear slide 2. Then, align the positioning pin at the bottom of the rotary shaft stage 3 with the positioning hole, and install the rotary shaft stage 3 into the circular groove 6 with appropriate pressure, ensuring a tight fit between the positioning pin and the positioning hole. During installation, ensure that the outer peripheral wall of the rotary shaft stage 3 is in close contact with the inner wall of the circular groove 6. Simultaneously, install an annular sealing ring 7 between the outer peripheral wall of the rotary shaft stage 3 and the inner wall of the circular groove 6 to achieve a good sealing effect. Furthermore, install an elastic buffer layer between the positioning pin and the positioning hole to mitigate the impact force during the installation of the rotary shaft stage 3.
[0040] After installation, the entire integrated CNC rotary table structure is debugged and tested. Check whether the linear slide 2 moves smoothly on the linear slide rail 1, whether the rotation of the rotary table 3 is flexible and accurate, and whether the connections between the components are firm. Through debugging and testing, ensure that the integrated CNC rotary table structure can operate normally and meet the requirements of CNC machining.
[0041] In actual use, according to the process requirements of CNC machining, the linear slide 2 is controlled by the CNC system to move linearly along the linear slide rail 1, while the rotary table 3 is controlled to rotate, so as to realize multi-dimensional machining of the workpiece. During the machining process, due to the advantages of high precision, high rigidity and low height of this integrated CNC rotary table structure, it can effectively improve machining accuracy and efficiency and ensure the machining quality of the workpiece.
[0042] This application discloses an integrated CNC rotary table structure. By eliminating the outer shell of the rotary axis table 3 and directly installing it within the circular groove 6 of the linear slide table 2, it eliminates assembly errors between the outer shell and the slide table, and between the outer shell and the rotary axis table 3, significantly improving the positioning accuracy of the rotary table and meeting the requirements of high-precision CNC machining. The omission of the outer shell makes the entire integrated CNC rotary table structure more compact, reducing the overall height of the rotary table, saving installation space, facilitating equipment integration and miniaturization, and improving the flexibility of spatial layout. The direct and tight fit between the rotary axis table 3 and the linear slide table 2 enhances the connection rigidity between them, reduces structural vibration and deformation, and improves the stability of the rotary table during machining, thereby improving the surface quality of the workpiece and the service life of the equipment. The rolling element between the slider 5 and the linear slide rail 1 reduces motion resistance and improves the motion accuracy and efficiency of the linear slide table 2. The elastic buffer layer alleviates installation impact and running vibration, further improving the overall performance of the rotary table. The annular sealing ring 7 effectively prevents foreign matter from entering the rotary table, protecting the core components and improving the reliability and service life of the rotary table.
[0043] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
