Technical Field

[0001] The present application relates to the field of drilling and milling machines, and more specifically, to a CNC gantry drilling and milling machine. Background Art

[0002] Drilling and milling machines are machine tools that integrate drilling, milling, boring and grinding. They are used for processing small and medium-sized parts. The worktable of drilling and milling machines can move vertically and horizontally, and the spindle is arranged vertically. They are usually desktop machines with machine heads that can be raised and lowered. They have multiple cutting functions such as drilling, milling, boring, grinding, and tapping. The spindle box can rotate 90° left and right in the vertical plane, and the worktable of some models can rotate 45° left and right in the horizontal plane. The worktable of most models can move the tool automatically in the vertical direction. When processing some plates, drilling operations need to be performed through drilling and milling machines.

[0003] The patent with application number 202022652984.5 discloses a CNC gantry drilling and milling machine, which relates to the field of mechanical processing technology. The utility model includes a workpiece, an X-axis slide rail, a sliding seat and a fixture assembly. The workpiece is slidably connected to the X-axis slide rail. The bottom of the X-axis slide rail is fixedly connected with a sliding seat near the two ends. The left end of the X-axis slide rail is fixedly connected with a control panel, and the control panel is electrically connected to the workpiece. The sliding seat is slidably connected to the Y-axis slide rail. Dust covers are fixedly connected to both the X-axis slide rail and the Y-axis slide rail. A fixture assembly is placed between the two Y-axis slide rails and on the front side of the X-axis slide rail. The fixture assembly of this application is placed between the dust cover and the Y-axis slide rail, and the cylinder head is clamped on the fixture assembly, which solves the problem that the existing radial drill processes the cylinder head of the drying cylinder, and the drilling accuracy is not high, which affects the processing quality of the cylinder head and the cylinder head placement platform used by the radial drill, and it is not convenient to quickly fix the cylinder head, thereby reducing the problem of rapid drilling of the cylinder head.

[0004] In response to the above-mentioned related technologies, the cylinder head is clamped on the clamp assembly by placing the clamping assembly between the dust cover and the Y-axis slide rail, thereby solving the problem of low drilling accuracy in the existing radial drill processing of the dryer cylinder head. However, the equipment may produce waste chips when drilling and milling the product, and the waste chips may splash everywhere, making it inconvenient for the staff to clean up later, and may accidentally injure the staff, reducing the safety of the equipment.

[0007] By adopting the above technical scheme, when the equipment is used, the staff places the plate on the top of the placement plate, and then clamps and fixes the plate through the limit assembly, which is conducive to maintaining the stability of the plate on the top of the placement plate, thereby helping to avoid the plate from offsetting during the drilling and milling process, and is conducive to improving the stability of the equipment's drilling and milling, and the limit assembly can adjust the position of the plate. After the plate is fixed, the plate can be drilled and milled by the drilling and milling equipment. When the drilling and milling equipment is processing, waste chips may be generated.

[0008] Furthermore, the driving assembly includes an installation box fixedly installed on a side of the base away from the installation seat, a reduction motor is fixedly installed in the installation box, two symmetrically distributed installation grooves are provided on the top of the base, and screws are rotatably installed in the two installation grooves, two screw side walls are sleeved with support blocks, and the tops of the two support blocks are fixedly connected to the bottom of the placement plate, the two screws are rotated and penetrated into the installation box at one end away from the installation seat, and the two screws passing through the installation box are fixedly sleeved with pulleys at one end, and a transmission belt is sleeved between the two pulleys, and one end of one of the screws passes through the installation box and is fixedly connected to the end of the output shaft of the reduction motor.

[0009] By adopting the above technical scheme, the connected screws are driven to rotate by a reduction motor, and a pulley and a transmission belt are provided between the two screws. The two screws are rotated synchronously through the cooperation of the pulley and the transmission belt.

[0010] Furthermore, triangular blocks are fixedly installed on both sides of the two support blocks, and two symmetrically distributed sealing gaskets are fixedly installed in the two installation grooves.

[0011] By adopting the above technical solution, the two installation grooves can close the installation groove ports through the setting of sealing gaskets, which helps to prevent waste chips from entering the installation grooves. The triangular blocks on both sides of the support block can push the sealing gaskets of the same group, making it easier to move the support block position.

[0012] Furthermore, the limiting assembly includes a cylinder fixedly mounted on the top of the mounting plate, the two cylinder piston shafts slide through the gantry, and the two cylinder piston shaft ends are fixedly mounted with frames, the two frames are rotatably mounted with limiting rollers distributed in a linear array, and the tops of the two frames are provided with pressing assemblies.

[0015] By adopting the above technical solution, when the limiting roller contacts the opposite side of the plate, the second telescopic rod drives the same group of pressing plates to move downward and contact the top of the plate, thereby further pressing and fixing the plate, which is beneficial to maintaining the stability of the equipment placement.

[0016] Furthermore, the debris filter assembly includes a filter frame fixedly mounted on the top of the mounting base, a conduit is connected between the filter frame and the vacuum pump, a telescopic hose is connected to the side of the filter frame away from the vacuum pump, and the telescopic hose is fixedly connected to a multi-way joint at one end away from the filter frame, a chip collecting bucket is fixedly connected to the multi-way joint at one end away from the filter frame, a filter plate and dust collecting cotton are slidably mounted in the filter frame, limit blocks are fixedly mounted on both sides of the filter plate and the dust collecting cotton, a limit groove is formed on the inner wall of the filter frame and matches the limit block on the same side, a cover plate is hinged on the top of the filter frame, and a rubber pad is provided at the bottom of the cover plate, and a telescopic assembly is provided between the filter frame and the chip collecting bucket.

Subsequently, the chip collecting bucket can be driven to move toward the drilling and milling equipment through the telescopic component, and suction can be generated by the vacuum pump, so that the waste chips pass through the chip collecting bucket and enter the telescopic hose. Subsequently, the waste chips enter the filter frame through the telescopic hose, which can collect the waste chips and help reduce the possibility of waste chips splashing everywhere. The filter frame plays a role in filtering waste chips through the filter plate and dust-absorbing cotton, which helps to prevent waste chips from entering the vacuum pump, reduces the degree of damage to the vacuum pump, and achieves the effect of protecting the vacuum pump. The filter plate and the dust-absorbing cotton are fixed by the limit block and the limit groove opened on the inner wall of the filter frame, which is convenient for the staff to disassemble and replace the filter plate and dust-absorbing cotton later, which is beneficial to maintain the filtering effect of the equipment.

[0018] Furthermore, the telescopic assembly includes a support plate fixedly mounted on the top of the chip collecting bucket, a first telescopic rod is fixedly mounted on the side of the filter frame away from the vacuum pump, and the end of the first telescopic rod is fixedly connected to the side opposite to the support plate.
