Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a vertical machine tool structure suitable for loading and unloading gantry robots. Background Technology

[0002] Vertical machine tools (vertical machining centers) are a common type of machining equipment. The spindle of a vertical machine tool is perpendicular to the horizontal worktable. The workpiece is mounted on the worktable, and cutting tools are installed on the spindle to perform multi-functional machining operations such as turning, milling, boring, and drilling. They are widely used. To ensure comprehensive machining of the workpiece on the worktable, the spindle centerline and the worktable centerline are aligned in both the Y and X axes. To improve the ease of workpiece mounting on the worktable, many machine tools now use five-axis articulated robots for loading and unloading. While these articulated robots are very flexible, they are very expensive. Current vertical machine tools are not suitable for three-axis gantry robots because the gantry robot interferes with the spindle head when loading and unloading in the Z-axis direction. Even if the worktable is moved to the outermost position in the Y-axis direction, the gantry robot will still interfere with the spindle head when loading and unloading, thus preventing normal loading and unloading. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a vertical machine tool structure suitable for loading gantry robots. This machine tool structure has a larger stroke in the Y direction, which allows the gantry robot to completely avoid the spindle box when loading and unloading, thus preventing interference between the gantry and the spindle box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vertical machine tool structure suitable for loading and unloading gantry robots includes a base and a column located at one end of the base. The column is equipped with a spindle box that can be raised and lowered in the Z direction. The base is equipped with a Y-axis slide rail, and the Y-axis slide rail is equipped with an X-axis slide rail. A horizontal worktable is provided on the X-axis slide rail. The spindle box contains a spindle perpendicular to the worktable. When the worktable moves to its outermost end along the Y-axis slide rail, the inner side of the worktable extends beyond the vertical plane containing the outer side of the spindle box, so that there is sufficient space directly above the worktable to facilitate the Z-axis raising and lowering of the gantry.

[0006] During loading and unloading, the worktable first moves to the outermost end of the Y-axis slide rail, then the gantry moves to the top of the worktable, and the gantry descends to the worktable via the Z-axis for loading and unloading. This type of vertical machine tool can be directly docked with the gantry robot, making loading and unloading more convenient, and the gantry will not interfere with the spindle box, resulting in better overall stability.

[0007] Preferably, when the worktable moves to its outermost end along the Y-axis slide rail, the distance between the inner side of the worktable and the vertical plane containing the outer side of the spindle box is L, which is configured to be 25-45mm. This distance ensures that the truss does not interfere with the spindle box and also prevents the Y-axis slide rail from being too long and affecting accuracy.

[0008] Preferably, the inner end face of the spindle box is used as the reference plane, the distance from the spindle axis to the reference plane is L1, and the distance from the outer end face of the spindle box to the reference plane is L2, with L1 / L2 configured to be 0.75-0.85. The positions of the spindle axis and the outer end face of the spindle box are limited to minimize the distance between them, and the travel of the worktable on the Y-axis slide rail is reduced as much as possible while meeting the requirements, thereby ensuring overall accuracy and stability.

[0009] Preferably, when the worktable moves to its outermost end along the Y-axis slide rail, the distance from the center of the worktable to the reference plane is L3, and the L2 / L3 is configured to be 0.62-0.75.

[0010] Preferably, the vertical machine tool is equipped with a protective compartment on its exterior, and a truss passage is provided at the top of the protective compartment. When the worktable moves to its outermost end along the Y-axis slide rail, the truss passage is located directly above the worktable. Many vertical machining centers have protective compartments on their exteriors. In this structure, a truss passage is directly provided at the top of the protective compartment, and the truss rises and falls directly from the top truss passage, allowing for loading and unloading without opening the compartment door, making it more convenient to use.

[0011] Preferably, the X-axis slide rail is connected to the Y-axis slide rail via a Y-axis slide saddle, and the worktable is connected to the X-axis slide rail via an X-axis slide saddle.

[0012] Preferably, the inner end of the base is provided with a connecting seat for connection with the column, and the connecting seat and the base are an integral structure; the cross-section of the base is an isosceles trapezoid, and the two sides of the top surface of the base extend outward to form convex strips, and several reinforcing ribs are provided between the bottom surface of the convex strips and the side surface of the base; the interior of the base is a hollow structure, and several integral reinforcing plates are provided inside the base in a staggered arrangement. Increasing the strength of the base ensures its rigidity, thereby ensuring the stability of the Y-axis slide rail.

[0013] Therefore, this invention can interface with gantry robots for loading and unloading, thereby improving the processing efficiency of workpieces. Attached Figure Description

[0023] like Figures 1-5 The illustrated vertical machine tool structure for loading and unloading gantry robots includes a base 1, a column 2 located at one end of the base, a Z-axis lifting spindle box 3 mounted on the column, a Y-axis slide rail 4 mounted on the base, an X-axis slide rail 5 mounted on the Y-axis slide rail 4, and a horizontal worktable 6 mounted on the X-axis slide rail. The X-axis slide rail is connected to the Y-axis slide rail via a Y-axis slide saddle, and the worktable is connected to the X-axis slide rail via the X-axis slide saddle. A spindle 7 perpendicular to the worktable is located inside the spindle box 3. When the worktable 7 moves along the Y-axis slide rail to its outermost position, the inner side of the worktable 6 extends beyond the vertical plane containing the outer side of the spindle box, providing sufficient space directly above the worktable 6 for the Z-axis lifting and lowering of the gantry 9. Figure 2 As shown, when the worktable moves along the Y-axis slide rail to the innermost end, the axis of the spindle is flush with or nearly flush with the outer surface of the worktable.

[0024] The inner end of the base 1 is provided with a connecting seat 100 for connecting with the column. The connecting seat and the base are an integral structure. The cross-section of the base 1 is an isosceles trapezoidal structure. The top surface of the base extends outward on both sides to form a protruding strip 101. A number of reinforcing ribs 102 are provided between the bottom surface of the protruding strip and the side surface of the base. The interior of the base 1 is a hollow structure. A number of integral reinforcing plates 103 are arranged in a staggered pattern inside the base.

[0025] like Figure 3 As shown, when the worktable 6 moves to its outermost end along the Y-axis slide rail 4, the distance between the inner side of the worktable 6 and the vertical plane containing the outer side of the spindle box is L, which is configured to be 25-45mm. The inner end face of the spindle box is used as the reference plane. Figure 3 The distance from the spindle axis to the reference plane is L1, and the distance from the outer end face of the spindle box to the reference plane is L2. The ratio of L1 / L2 is configured to be 0.75-0.85.

[0026] like Figure 6 As shown, in some embodiments, the vertical machine tool is provided with a protective cabin 8 on its exterior. The protective cabin 8 is provided with a door 80 near the outer end of the Y-axis slide rail. The top of the protective cabin is provided with a truss passage 81. When the worktable moves along the Y-axis slide rail to the outermost end, the truss passage is located directly above the worktable.

[0027] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 6 As shown, when worktable 6 needs to be loaded, worktable 6 moves to the outermost end of Y-axis slide rail 4. At this time, the inner side of the worktable exceeds the outer side of the spindle box. The truss 9 (with a gripper at the bottom) moves to the truss passage 81 at the top of the protective compartment. The truss descends onto the worktable to load the workpiece. The fixture on the worktable holds the workpiece, and the truss rises to reset. After the workpiece is processed by the vertical machine tool, it moves again to... Figure 6 As shown in the diagram, the gripper at the bottom of the gantry grasps the processed workpiece. This type of vertical machine tool can work with a gantry robot to achieve automatic loading and unloading, greatly improving processing efficiency.
