Description

Technical Field

[0001] The utility model relates to the technical field of limit tracks, and particularly relates to a limit track for a numerical control machining center. Background Technique

[0002] During the operation of a numerical control machining center, the limit track, as a key component, undertakes the important responsibility of ensuring that each moving part of the machine tool moves precisely within a predetermined range. These tracks not only need to have high precision, high wear resistance and good stability, but also need to adapt to the flexible adjustment requirements of the working space for different machining tasks. However, in the current design of the limit tracks for numerical control machining centers, there is generally a significant limitation - the upper and lower widths of the tracks are often designed as fixed dimensions and cannot be flexibly adjusted according to specific machining requirements. The limit tracks with fixed widths are unable to cope with diverse machining tasks. For example, when machining workpieces of different sizes or adjusting the stroke range of the machine tool workbench, if the track width cannot be adjusted accordingly, it will limit the machining ability and flexibility of the machine tool. Content of the Utility Model

[0003] (I) Purpose of the Utility Model

[0004] In view of this, the purpose of the present utility model is to provide a limit track for a numerical control machining center, which solves the problems raised in the above background.

[0005] (II) Technical Solution

[0006] A limit track for a numerical control machining center includes a mounting base. Both sides of the mounting base are fixedly installed with side plates. One side between the side plates is fixedly installed with an upper track. A groove is opened on one side of the side plate, and two groups of fixed seats are fixedly installed on the inner wall of the groove. Circular through grooves are opened on the outer surfaces of the two groups of fixed seats, and a lead screw is movably installed in the circular through grooves. A sliding seat is movably installed on the outer surface of the lead screw, and a connecting plate is connected to one side of the sliding seat. One end of the lead screw is connected to a motor, and the motor is fixedly connected to the fixed seat. The top end of the connecting plate is connected to a connecting rod, and lower tracks are connected to both sides of the connecting rod. A moving seat is movably installed between the lower track and the upper track.

[0007] Preferably, a protective plate is fixedly installed on the inner wall of the groove on one side of the side plate, and a limiting groove is opened on the outer surface of the protective plate. The connecting plate is movably engaged in the limiting groove.

[0008] Preferably, two groups of sliding grooves are opened on the outer surface of one side of the side plate, and sliders are movably installed on the inner walls of the two groups of sliding grooves. One end of the slider is connected to the lower track.

[0009] Preferably, multiple groups of connecting plates are fixedly installed on both sides of the mounting base, and multiple groups of screw grooves are opened on the outer surfaces of the multiple groups of connecting plates.

[0010] Preferably, a limiting plate is fixedly installed at the top of the side plate, and two mounting grooves are formed on the outer surface of the limiting plate. A first circular plate is fixedly installed on the inner wall of the two mounting grooves, and a damper is connected to one side of the first circular plate.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0024] A limit track for a numerical control machining center, including a mounting base 1. Both sides of the mounting base 1 are fixedly installed with side plates 2. And on one side between the side plates 2, an upper track 7 is fixedly installed. A groove is formed on one side of the side plate 2, and two groups of fixed seats 915 are fixedly installed on the inner wall of the groove. Circular through grooves are formed on the outer surfaces of the two groups of fixed seats 915, and a lead screw 914 is movably installed in the circular through grooves. A sliding seat 913 is movably installed on the outer surface of the lead screw 914. And one side of the sliding seat 913 is connected with a connecting plate 911. One end of the lead screw 914 is connected with a motor 916, and the motor 916 is fixedly connected with the fixed seat 915. The top end of the connecting plate 911 is connected with a connecting rod 9, and lower tracks 6 are connected to both sides of the connecting rod 9. A moving seat 5 is movably installed between the lower track 6 and the upper track 7.

[0025] Furthermore, a protection plate 912 is fixedly installed on the inner wall of the groove on one side of the side plate 2, and a limit groove is formed on the outer surface of the protection plate 912. The connecting plate 911 is movably engaged in the limit groove. By fixedly installing the protection plate 912 on the inner wall of the side plate groove and setting the limit groove to engage the connecting plate 911, this design not only enhances the stability of the sliding structure but also prevents the connecting plate 911 from shifting or falling off during movement, improving the safety of the overall structure.

[0026] Furthermore, two sets of sliding grooves 8 are provided on the outer surface of one side of the side plate 2, and sliders 711 are movably installed on the inner walls of the two sets of sliding grooves 8. One end of the slider 711 is connected to the lower rail 6. The sliding grooves 8 provide precise guidance for the movement of the lower rail 6, ensuring its stability and accuracy during the width adjustment process.

[0027] Furthermore, multiple sets of connecting plates 3 are fixedly installed on both sides of the mounting base 1, and multiple sets of screw grooves 4 are provided on the outer surfaces of the multiple sets of connecting plates 3. The multiple sets of connecting plates 3 enable the entire limiting rail to be conveniently connected and fixed to other machine tool components, improving the flexibility and convenience of installation.

[0028] Furthermore, a limiting plate 811 is fixedly installed at the top of the side plate 2, and two sets of mounting grooves 813 are provided on the outer surface of the limiting plate 811. A first circular plate 814 is fixedly installed on the inner walls of the two sets of mounting grooves 813, and a damper 815 is connected to one side of the first circular plate 814. One end of the damper 815 is connected to a spring 816, and a rubber airbag 812 is installed on one side of the spring 816. A spring 816 is connected between the first circular plate 814 and the second circular plate 817. The combined design of the first circular plate 814, the damper 815, the spring 816, and the rubber airbag 812 on the limiting plate 811 provides an effective buffering and shock-absorbing effect for the movement of the moving seat 5 between the upper and lower rails, reducing the impact of shock and vibration on the machine tool accuracy and component life.

[0029] Furthermore, both ends of the limiting plate 811 are arc-shaped, and the arc-shaped ends increase safety and prevent scratching.

[0030] Working principle: In the initial state, the lower track 6 is fixedly connected to the connecting plate 911 through the connecting rod 9, and the connecting plate 911 is connected to the sliding seat 913. The sliding seat 913 is movably installed on the lead screw 914, and the lead screw 914 passes through and is fixed in the circular through grooves of the fixed seats 915 on both sides. The motor 916 is fixedly connected to the fixed seat 915 and drives the lead screw 914 to rotate. When it is necessary to adjust the vertical width between the lower track 6 and the upper track 7, first start the motor 916, and the lead screw 914 starts to rotate. Due to the rotation of the lead screw 914, the sliding seat 913 that is in threaded engagement with the lead screw will perform a linear motion along the axial direction of the lead screw. The direction of this linear motion is upward or downward depending on the direction of the motor driving the lead screw to rotate. The movement of the sliding seat 913 will drive the connected connecting plate 911 to move synchronously. The top end of the connecting plate 911 is fixedly connected to the connecting rod 9. Therefore, when the connecting plate 911 moves, the connecting rod 9 will also move accordingly. Both ends of the connecting rod 9 are respectively connected to both sides of the lower track 6, ensuring that the lower track 6 can move as a whole along with the movement of the connecting rod 9. By continuously driving the motor 916 and controlling its rotation direction and rotation time, the moving distances of the sliding seat 913, the connecting plate 911, and the connecting rod 9 can be accurately controlled, thereby realizing the precise adjustment of the vertical width between the lower track 6 and the upper track 7. When the required width is reached, stop the rotation of the motor 916. At this time, the position of the lower track 6 is fixed to meet the requirements of the current processing task. After adjusting the vertical width, the moving seat 5 of the CNC machining center can move smoothly between the upper track 7 and the lower track 6 to perform precise processing tasks.
