Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a CNC machine tool guide rail structure. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] CNC machine tools are generally equipped with guide rails for guiding the movement of the internal mechanical structure. Touch-sensitive machine tools used for cutting, such as CNC, generate a large amount of metal chips when cutting metal materials. Since the slider moves closely along the guide rail, these chips do not affect the movement between the guide rail and the slider. However, the slider movement requires external power, such as a motor driving a lead screw. For example, in a CNC machine tool guide rail structure with prior art publication number CN220462937U, the end of the moving block on the lead screw is chamfered. When small chips fall onto the lead screw, they may enter between the lead screw and the moving block, causing severe wear on the lead screw and reducing its transmission stability. Some designs use flexible hoses on the lead screw, but these hoses can be damaged or aged over time due to expansion and contraction, requiring regular inspection or replacement. Therefore, this application proposes a CNC machine tool guide rail structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a CNC machine tool guide rail structure.

[0005] An embodiment of this utility model provides a CNC machine tool guideway structure, comprising:

[0006] Guide rail, on which a slider is slidably connected;

[0007] A drive protection component; the drive protection component includes a box-type base fixed to the bottom of the guide rail and capable of being installed on a CNC machine tool. A lead screw is rotatably installed inside the box-type base. A movable block that cooperates with the lead screw is sleeved on the outside of the lead screw. A detachable connecting rod is installed on the movable block and the slider. The rotation of the lead screw drives the movable block and the connecting rod to move, and drives the slider to move. The box-type base can shield and protect the lead screw.

[0008] Furthermore, the upper end of the slider is provided with multiple connecting grooves, which are arranged in a rectangular pattern.

[0009] Furthermore, the opening of the box-type base faces downward, and a strip groove is provided through the box-type base, through which the connecting rod passes and is slidably connected.

[0010] Furthermore, the box-type base is equipped with four fixing ears, which are arranged in a rectangular shape. The box-type base can be installed on a CNC machine tool by using bolts through the fixing ears.

[0011] Furthermore, the connecting rod is U-shaped, and a connecting bolt is rotatably connected to the end of the connecting rod. The slider and the moving block are provided with threaded grooves, and the connecting bolt engages in the threaded grooves.

[0012] Furthermore, a bearing is fitted onto the connecting rod and fixedly connected thereto, and the bearing is abutted against the inner bottom of the strip groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses a box-type base to shield and protect the lead screw, preventing debris from falling onto it and ensuring smooth contact between the lead screw and the moving block. This avoids the drawbacks of inspecting and replacing hoses in existing technologies, further reducing the workload of workers and lowering subsequent maintenance costs. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a CNC machine tool guideway structure, including:

[0022] Guide rail 2, with a sliding block 3 slidably connected on it. To facilitate connection with external accessories, the upper end of the slider 3 is provided with multiple connecting grooves, which are arranged in a rectangular shape. Connecting grooves can also be provided on the side of the slider 3. The inside of the connecting grooves can be threaded. The position of the connecting grooves is not limited to the position shown in the figure.

[0023] Drive protection assembly; The drive protection assembly includes a box-type base 1 fixed to the bottom of the guide rail 2 and capable of being installed on a CNC machine tool. The opening of the box-type base 1 is set downward. The box-type base 1 is equipped with four fixing ears 4, which are arranged in a rectangular shape. The box-type base 1 can be installed on the CNC machine tool by using bolts through the fixing ears 4.

[0024] A lead screw 7 is rotatably installed inside the box-type base 1. A motor can be installed on one side of the box-type base 1, and the output end of the motor is connected to the lead screw 7. Therefore, the operation of the motor can drive the lead screw 7 to rotate. A movable block 8 is sleeved on the outside of the lead screw 7. A detachable connecting rod 5 is installed on the movable block 8 and the slider 3. A strip groove 6 is provided through the box-type base 1. The connecting rod 5 passes through the strip groove 6 and is slidably connected to it.

[0025] Further explanation of the detachable connecting rod 5: The connecting rod 5 is U-shaped, and the end of the connecting rod 5 is rotatably connected to the connecting bolt 10. The slider 3 and the moving block 8 are provided with threaded grooves 9, and the connecting bolt 10 is engaged in the threaded grooves 9. In this way, the slider 3, the connecting rod 5 and the moving block 8 can be separated individually. When the slider 3, the connecting rod 5 or the moving block 8 is damaged, the damaged part can be disassembled individually.

[0026] Since the connecting rod 5 passes through the strip groove 6 and slides, in order to reduce the wear of the connecting rod 5, a bearing is fitted on the connecting rod 5 and fixedly connected to it. The bearing is set against the inner bottom of the strip groove 6, and the bearing is used to roll in the strip groove 6 instead of the roller, which can protect the connecting rod 5. A rubber diaphragm can be fixed on the outer wall of the bearing to protect the bearing.

[0027] The rotation of the lead screw 7 drives the moving block 8 and the connecting rod 5 to move, which in turn drives the slider 3 to move. The box-type base 1 can shield and protect the lead screw 7. In this way, when the CNC machine tool is working, it will not cause debris to fall on the lead screw 7, and will not affect the contact between the lead screw 7 and the moving block 8. This avoids the drawbacks of the existing technology of inspecting and replacing the hose, further reducing the workload of the staff and reducing the subsequent maintenance costs.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
