Description

Technical Field

[0001] The utility model relates to the technical field of numerical control mobile worktables, in particular to a numerical control mobile worktable. Background Art

[0002] A CNC mobile worktable is a metal cutting machine tool that utilizes numerical control technology to accurately perform specified processing actions according to a pre-arranged process flow. During the use of a CNC mobile worktable, workpiece processing debris will fall on the top of the worktable, which can easily affect the subsequent processing of the workpiece. To address this problem, the prior art has proposed a CNC mobile worktable with a self-cleaning function. In the related art, a CNC mobile worktable with a self-cleaning function usually uses a cleaning brush to automatically clean the worktable. However, since auxiliary components such as workpiece fixing fixtures need to be installed on the worktable during processing, and different workpieces may require different auxiliary components, the area required to be cleaned during use of the worktable varies. If an ordinary straight rod-shaped cleaning brush is used to clean the worktable, it is difficult to ensure that all parts of the worktable are effectively cleaned. Customizing a specific cleaning brush will increase production costs, and the replacement of the cleaning brush will reduce the cleaning efficiency of the worktable. In addition, processing debris is likely to fall on the worktable drive structure, affecting the operation of the worktable drive structure. Based on this, the present application proposes a CNC mobile worktable. Utility Model Content

[0022] The present invention provides a numerically controlled movable workbench, comprising a two-axis movable structure and a cleaning structure, wherein the two-axis movable structure comprises a transverse movable structure 14 and a longitudinal movable structure 11, wherein both the transverse movable structure 14 and the longitudinal movable structure 11 comprise a shell 1 and a shielding belt 13, wherein a movable groove is provided in the middle of the top of the shell 1, wherein a movable block 12 is movably connected to the inner cavity of the movable groove, and the movable block 12 is connected to the shell 1 through a power structure, and in some embodiments of the present application, the power structure comprises a ball screw 16 and a servo motor 17 movably connected to the inner cavity of the movable groove, wherein the output shaft end of the servo motor 17 is fixedly connected to the middle of one end of the ball screw 16 through a reducer, wherein the outer ring of the ball screw 16 is threadedly connected to a ball nut, and the movable block 12 is fixedly connected to the ball nut. Through the setting of the power structure, the rotation of the servo motor 17 can drive the ball screw 16 connected thereto to rotate, and the rotation of the ball screw 16 causes the ball nut threaded thereto to move in the direction of the ball screw 16, and when the ball nut moves, the movable block 12 is driven to move.

[0023] A connecting plate 2 is fixedly connected to one side of the housing 1 of the longitudinal movable structure 11. The movable block 12 of the transverse movable structure 14 is fixedly connected to the connecting plate 2. The top of the movable block 12 of the longitudinal movable structure 11 is fixedly connected to the workbench 3. When the transverse movable structure 14 is in operation, it can drive the longitudinal movable structure 11 to move. When the longitudinal movable structure 11 is in operation, it can drive the workbench 3 to move. The coordinated use of the transverse movable structure 14 and the longitudinal movable structure 11 allows the workbench 3 to move freely within the horizontal plane.

[0024] A guide block 15 is fixedly connected to the corner of the shell 1, and a shielding belt 13 is wrapped on the outer wall of the shell 1. The guide block 15 is in contact with the inner side of the shielding belt 13, and both ends of the shielding belt 13 are fixedly connected to the moving block 12. The top of the moving block 12 and the top of the shielding belt 13 connected thereto are at the same height, and the bottom of the straight section on the shielding belt 13 is in contact with the top of the shell 1. Through the setting of the shielding belt 13, the moving block 12 can drive the shielding belt 13 to move when it moves. The shielding belt 13 can always shield the shell 1 to prevent workpiece processing debris from falling on the shell 1, thereby facilitating the operation of the power structure.

[0025] The outer surface of the shielding tape 13 is coated with an anti-stick coating. The provision of the anti-stick coating facilitates separation of impurities dropped onto the shielding tape 13 from the shielding tape 13 , thereby facilitating cleaning of the shielding tape 13 .

[0026] A cleaning structure is provided at one end of the two-axis movable structure, which includes a support frame 4 and a fixed plate 7 connected to the top of the support frame 4 through a translation structure. The translation structure includes an electric telescopic rod 2 5 fixedly connected to the support frame 4, and the end of the output shaft of the electric telescopic rod 2 5 is fixedly connected to the electric telescopic rod 3 6, and the end of the output shaft of the electric telescopic rod 3 6 is fixedly connected to the fixed plate 7.

Through the setting of the electric telescopic rod 9, the extension and retraction of the electric telescopic rod 9 can change the position of the cleaning brush module 10 fixedly connected thereto. Two adjacent cleaning brush modules 10 are in a state of contact. The multiple cleaning brush modules 10 in this application constitute a cleaning brush for cleaning the workbench 3, and under the action of the electric telescopic rod 9, the shape of the cleaning brush can be changed, so that the cleaning brush can adapt to the different undulations on the workbench 3. The side of the fixed plate 7 close to the workbench 3 is fixedly connected to a visual sensor 8. Through the setting of the visual sensor 8, the cleaning area of the workbench can be detected, and the deformation of the cleaning brush can be controlled based on the detection results.

The following mainly introduces the working principles and processes, and no further explanation of the electrical control is given.

[0029] In summary: when the CNC mobile workbench is in use, the two-axis moving structure is used to drive the workbench 3 to move. During the movement of the moving block 12, the shielding belt 13 connected to it is driven to rotate, so that the shielding belt 13 can always block the top of the shell 1 to prevent the workpiece processing debris from affecting the work of the power structure, thereby preventing the workpiece processing debris from affecting the two-axis moving structure, making it easier for the controller of the workbench to control the movement of the workbench 3 using CNC technology. When the workbench 3 needs to be cleaned, the workbench 3 moves to the bottom of the cleaning brush, and the visual sensor 8 performs a visual inspection of the top of the workbench 3. The controller of the workbench controls the extension and retraction of the electric telescopic rod 9 based on the visual inspection results, so that the shape of the cleaning brush adapts to the workbench 3. The translation structure is used to drive the cleaning brush to move. The cleaning brush can sweep away the processing debris on the workbench, thereby cleaning the workbench and facilitating the reuse of the workbench.
