Description

Technical Field

[0001] The utility model relates to the technical field of numerical control gantry milling machines, in particular to a numerical control gantry milling machine capable of reducing scratches on a milling surface. Background Art

[0002] A CNC gantry milling machine, also known as a CNC gantry milling machine, is a milling machine with a portal frame and a long horizontal bed. Multiple milling cutters can be used simultaneously on a CNC gantry milling machine, achieving high precision and production efficiency. It is suitable for machining flat and inclined surfaces on large workpieces in batch and mass production. It can also process curved surfaces and some special-shaped parts. A CNC gantry milling machine consists of a base, a worktable, a gantry, and a rotating shaft housing mounted on the gantry. The housing is equipped with a drive shaft, and a milling cutter disc is mounted at the lower end of the drive shaft. The workpiece is placed on the worktable and secured. The milling cutter disc can move relative to the worktable on the X, Y, and Z axes, facilitating surface machining of the workpiece.

[0003] Regarding the above-mentioned related technologies, the inventors found that when the milling cutter of a CNC gantry milling machine performs horizontal surface processing on the workpiece on the worktable, the milling cutter produces a lot of waste chips. During the high-speed rotation of the milling cutter, it is easy to drive the waste chips to move quickly. The more moving waste chips are likely to cause scratches on the processed surface, affecting the surface roughness of the processed surface and reducing the processing quality. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a numerically controlled gantry milling machine based on reducing scratches on the milling surface, thereby solving the problem that many scratches on the machining surface are caused by waste chips.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a CNC gantry milling machine based on reducing scratches on the milling surface, comprising: a gantry milling machine body, the gantry milling machine body comprising a spindle box and a driving shaft body penetrating the spindle box, the lower end of the driving shaft body being connected to a milling cutter disc, the outer side of the driving shaft body being sleeved with a fixed tube body, the upper end of the fixed tube body being connected to the spindle box body, the outer side of the fixed tube body being sleeved with a rotating tube body, a bearing being connected between the inner wall of the rotating tube body and the outer circle of the fixed tube body, the outer circle surface of the rotating tube body being connected to a vertical adjustment component, the vertical adjustment component being connected to a V-shaped fixing rod, the oblique lower end of the V-shaped fixing rod being connected to a detachable horizontal connecting component, and the lower plane of the detachable horizontal connecting component being connected to a strip cleaning brush;

[0006] It also includes a rotation drive component for driving the rotating tube to rotate in a circle.

[0007] By adopting the above technical solution, when in use, the workpiece to be processed is placed on the workbench, and the workpiece and the workbench are fixed with a fixture. The active shaft on the gantry milling machine body rotates, thereby driving the milling cutter disc to perform surface processing on the workpiece. The milling cutter disc generates a lot of waste chips during the milling process. At this time, the rotating drive assembly drives the rotating tube body to rotate, and the rotating tube body drives the detachable horizontal connecting assembly on the V-shaped fixed rod to rotate in a circle. The detachable horizontal connecting assembly drives the strip cleaning brush to rotate, and the strip cleaning brush scrapes the waste chips around the milling cutter disc and on the workpiece, reducing the scratches on the processed surface caused by the rapid movement of the waste chips driven by the milling cutter disc, thereby improving the processing quality.

[0008] In a preferred example, the present invention can be further configured as follows: the vertical adjustment assembly includes a vertical T-shaped groove body and a vertical T-shaped block arranged in its inner cavity, the vertical T-shaped block is connected to the V-shaped fixing rod, and a first butterfly bolt is spirally penetrated on the vertical T-shaped block.

[0009] By adopting the above technical solution, after loosening the first butterfly bolt, the vertical T-shaped block is moved in the vertical direction to facilitate adjustment of the gap between the strip cleaning brush and the workpiece processing surface, thereby achieving a better cleaning effect. When the strip cleaning brush is worn to a certain extent, the vertical T-shaped block can be moved downward, and the strip cleaning brush can continue to clean the waste chips around the milling cutter disc, thereby extending the service life of the strip cleaning brush.

[0010] In a preferred example, the present invention can be further configured as follows: the detachable horizontal connecting assembly includes a horizontal T-shaped groove body and a horizontal T-shaped block arranged in its inner cavity, the lower plane of the horizontal T-shaped block is connected to the strip cleaning brush by screws, and a second butterfly bolt is spirally penetrated on the horizontal T-shaped groove body.

[0011] By adopting the above technical solution, when the strip cleaning brush is worn and cannot be used, after loosening the second butterfly bolt, the horizontal T-shaped block is removed from the horizontal T-shaped slot body, and the strip cleaning brush is replaced after loosening the screw, thereby improving the convenience of maintenance.

[0012] In a preferred example, the present invention can be further configured as follows: the rotary drive assembly includes a mounting plate, an outer gear ring and a driving gear meshing with the outer gear ring, the outer gear ring is sleeved and connected to the outer circle of the rotating tube body, the mounting plate is connected to the spindle box, a driving motor is mounted on the mounting plate, and the driving gear is sleeved on the output shaft of the driving motor.

[0013] By adopting the above technical solution, the driving motor drives the active gear to rotate, the active gear drives the outer ring gear to rotate, the outer ring gear drives the V-shaped fixed rod on the outer circle of the rotating tube to rotate, and the V-shaped fixed rod drives the strip cleaning brush to rotate through the detachable horizontal connecting assembly. The strip cleaning brush scrapes the waste chips on the workpiece and away from the milling cutter disc.

[0014] In a preferred example, the present invention can be further configured as follows: the strip-shaped cleaning brush is arranged to be inclined, suitable for driving waste chips produced by the milling cutter disc to move outward.

[0015] By adopting the above technical solution, since the strip cleaning brush is arranged at an angle, the strip cleaning brush scrapes the waste chips outward, thereby reducing the rapid movement of the waste chips driven by the milling cutter disc.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] The rotary drive assembly drives the V-shaped fixed rod connected to the rotating tube body to rotate in a circle. The V-shaped fixed rod drives the strip cleaning brush to rotate through the detachable horizontal connecting assembly. The strip cleaning brush scrapes the waste chips around the milling cutter disc and on the workpiece, reducing the scratches on the processing surface caused by the rapid movement of the waste chips driven by the milling cutter disc, thereby improving the processing quality.
