Description

Technical Field

[0001] The utility model belongs to the technical field of numerically controlled machine tools, and in particular relates to a machine tool column with a shield structure. Background Art

[0002] The machine tool column is a key supporting component in CNC machine tools, milling machines and other processing equipment. It is mainly responsible for carrying important components such as the spindle box and tool magazine, and ensuring sufficient rigidity and stability during the processing. In traditional machine tool design, the column structure is usually composed of high-strength cast iron or welded steel structure to provide the necessary support and seismic resistance.

[0003] During the long-term processing, due to the limitations of the machine tool structure, especially when performing high-precision operations such as metal cutting, the chips generated and the coolant used often inevitably enter the moving parts of the machine tool, such as the structure that drives the processing head up and down. These foreign objects will accumulate over time and affect the machine tool's motion performance and positioning accuracy, thereby reducing the processing accuracy. Utility Model Content

[0004] The purpose of the utility model is to provide a machine tool column with a shield structure to address the above-mentioned technical problems, so as to effectively isolate chips and coolant, ensure long-term stable operation without affecting the normal function and operational convenience of the machine tool, thereby improving the overall processing accuracy and production efficiency.

[0005] In view of this, the utility model provides a machine tool column with a shield structure, which is characterized by comprising:

[0006] A column base, a column body is fixedly arranged above the column base, and the column body is arranged in the air;

[0007] A processing base, which is movably arranged on the front of the column body and is used to install a processing head;

[0008] A lifting structure, which is vertically arranged on the front of the column body and is used to drive the processing base to move up and down;

[0009] A shield structure, which is arranged between the machining base surface and the column base and is used to prevent chips and coolant from contacting the lifting structure;

[0010] Wherein, the shield structure is telescopically arranged.

[0011] In this technical solution, the column body can be installed in the machine tool through the column base. When the machine tool processes the workpiece, the lifting structure can control the processing base to move up and down along the vertical direction of the column. The shield structure arranged on the front of the column can separate the chips and coolant from the lifting structure to prevent the chips and coolant generated by the processing from contacting the lifting structure, thereby protecting the lifting structure from damage, which is beneficial to improving the overall processing accuracy and production efficiency, and extending the service life of the lifting structure.

[0012] In the above technical solution, further, the shield structure includes:

[0013] A cover body, wherein the cover body is provided with a plurality of covers, the plurality of cover bodies are successively reduced in size and slidably sleeved with each other;

[0014] A bottom plate and a top plate, wherein the bottom plate and the top plate are respectively arranged at the bottom of the inner wall of the cover and the top of the outer wall of the cover, and the top surface of the bottom plate and the bottom surface of the top plate between adjacent covers abut against each other;

[0015] A mounting groove, wherein the mounting groove is arranged at the bottom of the processing base, and a mounting block is detachably arranged in the mounting groove, and a rubber pad is arranged between the mounting block and the mounting groove;

[0016] A groove is arranged on the bottom surface of the installation groove, and the uppermost cover top plate is installed in the groove.

[0017] In the present technical solution, the shield structure is designed to be a plurality of cover bodies which are nested with each other. These cover bodies are successively reduced in size and can slide against each other, thereby allowing the shield structure to be extended and retracted. Each larger cover body can slide outside the smaller cover body, and the processing base is driven up and down by the lifting structure, thereby realizing the extension and contraction of the shield. Through the coordination between the provided mounting blocks, rubber pads, and grooves, it is possible to prevent the coolant from entering the inner side of the cover body through the connection gap between the cover body and the processing base. It can effectively prevent the chips from contacting the coolant with the lifting structure, which is beneficial to improving the overall processing accuracy and production efficiency, and extending the service life of the lifting structure.

[0018] In the above technical solution, further, a rubber strip is embedded on the inner wall of the bottom plate, and the outer wall of the rubber strip can contact with the outer wall of the next cover body.

[0019] In the present technical solution, the rubber strips provided can further improve the sealing between the covers, effectively preventing foreign matter such as chips and coolant from entering the lifting structure.

[0025] A cushion block is arranged on the top of the column base, and a bearing is arranged between the cushion block and the reciprocating screw rod.

[0026] In the present technical solution, through the cooperation between the set protrusion and the guide rail, a cavity that can accommodate the reciprocating screw and the lifting and lowering of the processing base is formed on the front side of the column, and the reciprocating screw is driven to rotate by the set drive motor, thereby driving the processing base to move up and down, wherein the lowermost cover plate is connected to the outer wall of the pad.

[0027] In the above technical solution, further, the cover body is U-shaped, and the top end of the U-shape is bent toward the avoidance groove provided on the side wall of the protrusion.

[0028] In the present technical solution, the cooperation between the U-shaped cover body with the top bent toward the air avoidance groove and the air avoidance groove can reduce the entry of chips and coolant from the back of the cover body, thereby improving the protectiveness of the shield structure.
