Description

Technical Field

[0001] This utility model relates to the field of gantry milling machine technology, and in particular to a CNC gantry milling machine that facilitates workpiece position adjustment. Background Technology

[0002] A CNC gantry milling machine, or CNC milling cutter for short, is a milling machine with a gantry frame and a horizontal long bed. CNC gantry milling machines offer high machining accuracy and production efficiency, making them suitable for machining large workpieces' planes and inclined surfaces in batch and mass production. They can also machine spatial curved surfaces and some special-shaped parts. A CNC gantry milling machine includes a base, a worktable, a gantry frame, and a spindle box mounted on the gantry frame. The spindle box houses the drive spindle, and the milling cutter is mounted at the lower end of the drive spindle. The workpiece is placed on and fixed on the worktable, and the milling cutter moves relative to the worktable to facilitate machining.

[0003] Regarding the aforementioned technologies, the inventors discovered that before machining a workpiece using a CNC gantry milling machine, a crane must be used to hoist the workpiece onto the worktable. Next, the worker adjusts the workpiece's position appropriately to ensure that its length or width is parallel to the worktable's movement direction, thereby improving the milling accuracy. However, when fine-tuning the workpiece's position, the worker typically uses a tool (such as a wooden stick) to strike and move the workpiece. This method increases the worker's labor intensity and reduces the ease of operation. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a CNC gantry milling machine that facilitates the adjustment of workpiece position, thereby reducing the labor intensity of workers and enhancing the convenience of operation.

[0005] To solve the above-mentioned technical problems, the present invention provides a CNC gantry milling machine that facilitates workpiece position adjustment, comprising: a base, a worktable, a gantry frame, and a spindle housing mounted on the gantry frame. A spindle body is installed inside the spindle housing. A rotary adjustment rod assembly is provided above the worktable, and lifting rod assemblies are provided on both sides of the worktable. A transverse sliding assembly is connected between the upper ends of the lifting rod assemblies, and the transverse sliding assembly is connected to the rotary adjustment rod assembly. The invention also includes a linear drive mechanism connected to the lifting rod assemblies on both sides of the worktable.

[0006] By adopting the above technical solution, during operation, the overhead crane hoists the workpiece onto the worktable. When the position of the workpiece needs to be adjusted, the linear drive mechanism is operated to drive the horizontal sliding assembly to move closer to the workpiece via the lifting rod assembly. Based on the force point of the workpiece at an appropriate height, the lifting rod assembly is operated to drive the horizontal sliding assembly to move vertically, so that the rotary adjustment rod assembly corresponds to the force point in the height direction. Since the rotary adjustment rod assembly is connected to the horizontal sliding assembly, the rotary adjustment rod assembly can be manually operated to move an appropriate distance along the width direction of the worktable. The rotary adjustment rod assembly is then operated to push the workpiece closer to the force point in the side area, causing the workpiece to rotate and move in place. This makes it easier for the length or width direction of the workpiece to be parallel to the movement direction of the worktable, improving the machining accuracy of the gantry milling machine. It eliminates the need for workers to repeatedly strike the workpiece with tools for fine-tuning, reducing the labor intensity of workers and improving the convenience of operation.

[0007] In a preferred embodiment, the present invention can be further configured such that: the rotary adjusting rod assembly includes a movable seat and a nut seat embedded in the movable seat, the nut seat is internally threaded with a rotary screw, one end of the rotary screw is fitted with a wear-resistant cylinder, and the other end is connected with a rod-shaped handle.

[0008] By adopting the above technical solution, the rotating rod-shaped handle drives the rotating screw to rotate, the rotating screw moves in the axial direction, and the rotating screw pushes the workpiece to rotate through the wear-resistant cylinder, so that the length or width direction of the workpiece is parallel to the movement direction of the worktable.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the lifting rod assembly includes an outer tube and an inner tube slidably connected to its inner cavity, and also includes a push rod for driving the inner tube to move. The push rod includes a mounting plate, a connecting plate, and an electric push rod fixed on the mounting plate. The extended end of the electric push rod is connected to the connecting plate. The connecting plate is fixedly connected to the transverse sliding assembly. The mounting plate is connected to the outer tube.

[0010] By adopting the above technical solution, the telescopic rod of the electric push rod one extends and retracts, thereby driving the inner tube to slide inside the outer tube. The inner tube drives the horizontal sliding assembly to move in the vertical direction, that is, the height position of the rotating adjustment rod assembly is adjusted.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the lateral sliding assembly includes two L-shaped rods symmetrically arranged in the vertical direction, with a fixed rod connected between each end of the L-shaped rod, the lower end of the fixed rod connected to the upper end of the lifting rod assembly, and lateral guide rails connected to the inner walls of the L-shaped rods, with the rotary adjusting rod assembly connected between the lateral guide rails.

[0012] By adopting the above technical solution, since the rotary adjustment rod assembly is connected to two transverse guide rails, it is convenient to manually operate the rotary adjustment rod assembly to move along the width direction of the worktable.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the linear drive mechanism includes a U-shaped rod and strip support plates connected to both sides of the worktable. Longitudinal guide rails are respectively connected to the strip support plates. The longitudinal guide rails are connected to the corresponding lifting rod assemblies. The ends of both sides of the U-shaped rod are connected to the corresponding lifting rod assemblies. An electric push rod II is installed on the U-shaped rod. The extended end of the electric push rod II is connected to the worktable.

[0014] By adopting the above technical solution, the lateral sliding component is connected to the corresponding longitudinal guide rail through the lifting rod components at both ends. The telescopic rod of the electric push rod II extends and retracts, thereby driving the lifting rod component and the lateral sliding component to move along the length direction of the longitudinal guide rail.

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] When adjustments to the workpiece on the worktable are required, the height of the transverse sliding assembly is adjusted by operating the lifting rod assembly. Since the rotary adjustment rod assembly is connected to the transverse sliding assembly, it is easy to manually adjust the appropriate position of the rotary adjustment rod assembly in the width direction of the worktable. Operating the rotary adjustment rod assembly causes the wear-resistant cylinder at the end of the rotating screw to push the workpiece closer to the force point in the side area, thereby allowing the workpiece to rotate appropriately in place. This makes it easier for the length or width direction of the workpiece to be parallel to the movement direction of the worktable, improving the machining accuracy of the gantry milling machine. It eliminates the need for workers to repeatedly strike the workpiece with tools for fine-tuning, reducing the labor intensity of workers and improving the convenience of operation.

[0029] Reference Figures 1-4 This utility model discloses a CNC gantry milling machine that facilitates workpiece position adjustment, comprising: a base 1, a worktable 2, a gantry frame 3, and a spindle housing 4 mounted on the gantry frame 3. A spindle body 5 is installed inside the spindle housing 4. A milling cutter is installed at the lower end of the spindle body 5, and a crane is used to lift the workpiece and place it at a suitable position on the worktable 2.

[0030] A rotary adjustment rod assembly 60 is provided above the workbench 2, and lifting rod assemblies 70 are provided on both sides of the workbench 2. A transverse sliding assembly 80 is connected between the upper ends of the lifting rod assemblies 70, and the transverse sliding assembly 80 is connected to the rotary adjustment rod assembly 60.

[0031] The rotary adjustment rod assembly 60 includes a movable base 61 and a nut seat 62 embedded in the movable base 61. A rotary screw 63 is internally threaded onto the nut seat 62. One end of the rotary screw 63 is fitted with a wear-resistant cylinder 64, and the other end is connected to a rod-shaped handle 65. The wear-resistant cylinder 64 is made of polytetrafluoroethylene rod. Rotating the rod-shaped handle 65 drives the rotary screw 63 to rotate, and the rotary screw 63 moves in the axial direction. The rotary screw 63 pushes the workpiece to rotate through the wear-resistant cylinder 64, so that the length or width direction of the workpiece is parallel to the movement direction of the worktable. When the workpiece is heavy, a round tube can be fitted onto the rod-shaped handle 65 to drive the rotary screw 63 to rotate, which has the effect of saving effort.

[0032] The lifting rod assembly 70 includes an outer tube 71 and an inner tube 72 slidably connected to its inner cavity. It also includes a push rod 73 that drives the inner tube 72 to move. The push rod 73 includes a mounting plate 731, a connecting plate 732, and an electric push rod 733 fixed on the mounting plate 731. The extended end of the electric push rod 733 is connected to the connecting plate 732. The connecting plate 732 is fixedly connected to the transverse sliding assembly 80. The mounting plate 731 is connected to the outer tube 71. The telescopic rod of the electric push rod 733 extends and retracts, thereby driving the inner tube 72 to slide inside the outer tube 71. The inner tube 72 drives the transverse sliding assembly 80 to move in the vertical direction, that is, the height position of the rotating adjustment rod assembly 60 is adjusted.

[0033] The transverse sliding assembly 80 includes two L-shaped rods 81 arranged symmetrically in the vertical direction. Fixed rods 82 are connected between the two ends of the L-shaped rods 81. The lower end of the fixed rods 82 is connected to the upper end of the lifting rod assembly 70. Transverse guide rails 83 are connected to the inner walls of the L-shaped rods 81. The rotary adjustment rod assembly 60 is connected between the transverse guide rails 83. Since the rotary adjustment rod assembly 60 is connected to the two transverse guide rails 83, it is convenient to manually operate the rotary adjustment rod assembly 60 to move along the width direction of the worktable 2.

[0034] It also includes a linear drive mechanism 90, which is connected to the lifting rod assemblies 70 on both sides of the worktable 2. The linear drive mechanism 90 includes a U-shaped rod 91 and strip support plates 92 connected to both sides of the worktable 2. Longitudinal guide rails 93 are connected to the strip support plates 92 respectively. The longitudinal guide rails 93 are connected to the corresponding lifting rod assemblies 70. The ends of both sides of the U-shaped rod 91 are connected to the corresponding lifting rod assemblies 70. An electric push rod 94 is installed on the U-shaped rod 91. The extended end of the electric push rod 94 is connected to the worktable 2. The transverse sliding assembly 80 is connected to the corresponding longitudinal guide rail 93 through the lifting rod assemblies 70 at both ends. The telescopic rod of the electric push rod 94 extends and retracts, thereby driving the lifting rod assembly 70 and the transverse sliding assembly 80 to move along the length direction of the longitudinal guide rail 93.

[0035] The implementation principle of this embodiment is as follows: During use, the overhead crane hoists the workpiece onto the worktable 2. When the position of the workpiece needs to be adjusted, the linear drive mechanism 90 is operated to drive the horizontal sliding assembly 80 to move closer to the workpiece through the lifting rod assembly 70. According to the force point of the workpiece at an appropriate height, the lifting rod assembly 70 is operated to drive the horizontal sliding assembly 80 to move in the vertical direction, so that the rotating adjustment rod assembly 60 corresponds to the force point in the height direction. Since the rotating adjustment rod assembly 60 is connected to the horizontal sliding assembly 80, the rotating adjustment rod assembly 60 is manually operated to move an appropriate distance along the width direction of the worktable 2. The rotating adjustment rod assembly 60 is operated to push the workpiece closer to the force point in the side area, so that the workpiece rotates and moves in place. This makes it easier for the length or width direction of the workpiece to be parallel to the movement direction of the worktable, which improves the machining accuracy of the gantry milling machine. It eliminates the need for workers to use tools to repeatedly hit the workpiece for fine adjustment, reduces the labor intensity of workers, and improves the convenience of operation.
