DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Embodiment one: please refer to Figures 1 to 4The numerical control turning and milling machine tool gantry worktable comprises a worktable body 1, and a gantry 2 movably arranged on the top of the worktable body 1 along the length direction of the worktable body 1. In the embodiment, the linear guide rail system is adopted to move the gantry 2 along the length direction of the worktable body 1. A sliding plate is connected to the gantry 2 through another set of linear guide rail system, and a cutting tool is connected to the sliding plate through a gas cylinder. The workpiece to be processed is placed on the upper surface of the worktable body 1, and then the gantry 2 is moved along the length direction of the worktable body 1, the sliding plate is moved along the width direction of the worktable body 1, and the cutting tool is moved up and down, so that the relative movement of the workpiece and the tool can be realized to adapt to different processing requirements, and the workpiece is subjected to cutting processing. The generated waste chips are left on the upper surface of the worktable body 1 during the processing.

[0029] The embodiment further comprises two chip containing boxes 3, a fixed plate 4, a movable plate 5, a cleaning brush 7 and a jacking mechanism 9.

[0030] The two chip containing boxes 3 are respectively detachably connected to the two ends of the worktable body 1 along the length direction, the upper end of the chip containing box 3 is open, and the upper end surface of the chip containing box 3 does not exceed the upper surface of the worktable body 1, so as to collect the waste chips cleaned from the upper surface of the worktable body 1. The fixed plate 4 is fixed to the gantry 2, and in the embodiment, the fixed plate 4 is fixed to the cross beam of the gantry 2 and can move with the gantry 2, so as to install other components.

[0031] Secondly, the movable plate 5 is movably arranged above the fixed plate 4 and can move up and down. A plurality of connecting rods 6 are fixed in parallel and at intervals at the bottom of the movable plate 5, and each connecting rod 6 is movably arranged through the fixed plate 4 along the vertical direction. The cleaning brush 7 is detachably connected to the lower end of each connecting rod 6, and the cleaning brush 7 is arranged along the width direction of the worktable body 1 and used for cleaning the upper surface of the worktable body 1. When the gantry 2 moves along the length direction of the worktable body 1, the waste chips on the upper surface of the worktable body 1 can be cleaned into the chip containing box 3 through the cleaning brush 7. The compression spring 8 located between the cleaning brush 7 and the fixed plate 4 is sleeved on each connecting rod 6, and used for pressing the cleaning brush 7 downward, so that the cleaning brush 7 is tightly attached to the upper surface of the worktable body 1, thereby ensuring the cleaning effect.

[0032] In the embodiment, the top of the cleaning brush 7 is fixed with the mounting sleeve 10 corresponding to each connecting rod 6, the lower end of each connecting rod 6 is movably inserted into the corresponding mounting sleeve 10, and the screw for locking the connecting rod 6 is arranged on each mounting sleeve 10. The cleaning brush 7 is detachably connected to the connecting rod 6 through the cooperation of the mounting sleeve 10 and the screw. When the cleaning brush 7 is seriously worn and cannot be used, the screw is first removed, so that the mounting sleeve 10 and the connecting rod 6 are separated, thereby the cleaning brush 7 is removed and replaced, and the structure is simple and the operation is convenient. The structure also facilitates the replacement of the compression spring 8.

[0033] The lifting mechanism 9 is described in detail below:

[0034] The lifting mechanism 9 is provided on the fixed plate 4 and is used to lift the movable plate 5 so as to move the cleaning brush 7 away from the workbench body 1. Specifically, the lifting mechanism 9 includes a fixing nut 901 fixed on the fixed plate 4, an adjusting screw 902 arranged in the vertical direction is connected to the internal thread of the fixing nut 901, a handle 903 is fixed to the lower end of the adjusting screw 902, and a lifting plate 904 located below the movable plate 5 is fixed to the upper end of the adjusting screw 902. By driving the adjusting screw 902 to rotate by the handle 903, the lifting plate 904 can be driven to move upward through the cooperation of the adjusting screw 902 and the fixing nut 901; when the lifting plate 904 contacts the movable plate 5, the movable plate 5 can be driven to move upward, thereby driving the cleaning brush 7 away from the workbench body 1, thereby avoiding the cleaning brush 7 from contacting the workpiece during the processing of the workpiece. When it is necessary to clean the upper surface of the workbench body 1, turn the adjusting screw 902 to move the lifting plate 904 downward until it is no longer in contact with the movable plate 5. At this time, under the action of the compression spring 8, the cleaning brush 7 can be in close contact with the upper surface of the workbench body 1; then the gantry 2 moves back and forth along the length direction of the workbench body 1, and the waste chips on the upper surface of the workbench body 1 can be cleaned into the chip holding box 3 through the cleaning brush 7.

[0035] Preferably, a locking screw 11 is fixed to the top of the lifting plate 904, and an opening for the locking screw 11 to pass through is opened on the movable plate 5. A locking nut 12 is threadedly connected to the upper end of the locking screw 11. After the movable plate 5 is lifted upward by the lifting plate 904 until the cleaning brush 7 is away from the workbench body 1, the locking nut 12 can be tightened to prevent the movable plate 5 and the lifting plate 904 from moving relative to each other, thereby preventing the vibration force generated when cutting the workpiece from causing the movable plate 5 to shake up and down. When the workbench body 1 needs to be cleaned, the locking nut 12 is unscrewed, and then the adjustment screw 902 is rotated to move the lifting plate 904 downward until it is no longer in contact with the movable plate 5.

[0036] In the embodiment, the cleaning brush 7 comprises a second main brush 703 arranged along the width direction of the workbench body 1, and the mounting sleeve 10 is fixed to the upper surface of the second main brush 703. Side brushes 704 are fixed to both ends of the second main brush 703 and arranged along the length direction of the workbench body 1. Each side brush 704 cooperates with the second main brush 703 to form an H-shaped structure, and the width of the H-shaped structure is the same as the width of the workbench body 1. When the H-shaped structure moves along the length direction of the workbench body 1, the debris on the upper surface of the workbench body 1 can be collected between the two side brushes 704, so that the debris can be collected into the chip containing box 3 as much as possible, and the excessive debris can be prevented from moving to the two sides of the workbench body 1 along the side direction of the second main brush 703 and falling from the two sides of the workbench body 1.

[0037] Embodiment two: please refer to Figure 5 The difference between the embodiment and the embodiment one is that:

[0038] The cleaning brush 7 comprises a first main brush 701 arranged along the width direction of the workbench body 1, and V-shaped brushes 702 are fixed to both ends of the first main brush 701. In this way, when the upper surface of the workbench body 1 is cleaned, the debris can also be collected between the two V-shaped brushes 702 as much as possible, and the excessive debris can be prevented from moving to the two sides of the workbench body 1 along the side direction of the first main brush 701 and falling from the two sides of the workbench body 1.
