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 with an auxiliary workpiece fine-tuning function. 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. CNC gantry milling machines offer high precision and production efficiency, making them suitable for machining flat and inclined surfaces on large workpieces in batch and mass production. They 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 spindle housing mounted on the gantry. The spindle housing is equipped with a drive spindle, and a milling cutter is mounted at its lower end. The workpiece is placed on the worktable and secured, and the milling cutter moves relative to the worktable to facilitate machining.

[0003] With respect to the above-mentioned related technologies, the inventors found that before using a CNC gantry milling machine to process a larger workpiece, the workpiece must first be hoisted onto a workbench using a crane. Next, the worker adjusts the position of the workpiece appropriately so that the length or width direction of the workpiece is parallel to the moving direction of the workbench (2), thereby increasing the processing accuracy of the milling cutter on the workpiece. When fine-tuning the position of the workpiece, the worker usually uses a tool (such as a wooden stick) to hit the workpiece to move it. This operation method increases the labor intensity of the workers and reduces the convenience of operation. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a CNC gantry milling machine with an auxiliary workpiece fine-tuning function, which reduces the labor intensity of workers and improves the convenience of operation.

[0005] In order to solve the above technical problems, the present invention adopts a technical solution: providing a CNC gantry milling machine with an auxiliary workpiece fine-tuning function, comprising: a base, a worktable, a gantry, and a spindle housing mounted on the gantry, wherein both sides of the gantry are respectively connected to a swingable telescopic auxiliary adjustment rod mechanism;

[0006] The telescopic auxiliary adjustment rod mechanism includes a rotating shaft seat and a telescopic rod assembly connected thereto, one end of the telescopic rod assembly is connected to a sleeve, a sliding rod is provided in the sleeve, and both ends of the sliding rod are respectively penetrated by an adjustment rod assembly;

[0007] It also includes a circumferential limiting assembly, which is suitable for preventing the telescopic rod assembly in the horizontal and vertical directions from swinging.

[0008] By adopting the above technical solution, during use, a crane is used to lift a larger workpiece onto the workbench. When the position of the workpiece needs to be adjusted, the circumferential limit assembly is operated to rotate the telescopic rod assembly to a horizontal state. After operating the telescopic rod assembly to drive the sleeve to move appropriately, the adjusting rod assemblies at both ends of the sliding rod are close to the side of the workpiece. Next, the adjusting rod assembly is operated to move axially. The adjusting rod assembly drives the end of the workpiece to be appropriately offset in a direction perpendicular to the movement of the workbench, so that the length or width direction of the workpiece is parallel to the movement direction of the workbench, thereby improving the processing accuracy of the gantry milling machine on the workpiece, eliminating the need for workers to use tools to hit the workpiece multiple times to fine-tune it, reducing the labor intensity of workers and improving the convenience of operation.

[0009] In a preferred example, the present invention can be further configured as follows: the rotating shaft seat includes a fixed seat and a support shaft passing through the fixed seat and rotatably connected thereto, the fixed seat is connected to the gantry, and one end of the support shaft is connected to the telescopic rod assembly.

[0010] By adopting the above technical solution, since the support shaft is rotatably connected to the fixed seat, the telescopic rod assembly is convenient for swinging. When the position of the workpiece is adjusted using the adjusting rod assembly, the telescopic rod assembly is swung to a vertical state after operating the circumferential limit assembly, thereby preventing the telescopic auxiliary adjusting rod mechanism from affecting the worker's operation of the gantry milling machine.

[0011] In a preferred example, the present invention can be further configured as follows: the telescopic rod assembly includes a guide tube and a telescopic rod body arranged in its inner cavity, and also includes a linear limiter that prevents the telescopic rod body from moving along the length direction of the guide tube, and one end of the telescopic rod body is connected to the sleeve.

[0012] By adopting the above technical solution, after the telescopic rod body is adjusted along the length direction of the guide tube, the linear limiter is operated to fix the telescopic rod body relative to the guide tube.

[0013] In a preferred example, the present invention can be further configured as follows: the linear limiter includes an L-shaped seat connected to the guide tube and a first butterfly bolt screwed through the L-shaped seat, and the telescopic rod body is provided with a plurality of limit holes adapted to the ends of the first butterfly bolt.

[0014] By adopting the above technical solution, the telescopic rod is appropriately adjusted along the length direction of the guide tube, and the first butterfly bolt is rotated so that its end enters the corresponding limiting hole, thereby achieving the purpose of limiting.

[0015] In a preferred example, the present invention can be further configured as follows: the adjusting rod assembly includes a threaded tube body embedded in the sliding rod, a threaded adjusting rod is spirally connected to the threaded tube body, one end of the threaded adjusting rod is connected to a handle, and the other end is connected to a wear-resistant plastic block.

[0016] By adopting the above technical solution, the rotating handle drives the threaded adjustment rod to rotate, the threaded adjustment rod produces axial movement, and the threaded adjustment rod pushes the workpiece through the wear-resistant plastic block for fine adjustment. The structure is simple and the operation is convenient.

[0017] In a preferred example, the present invention can be further configured as follows: the circumferential limit assembly includes a support seat and a second butterfly bolt spirally inserted into the support seat, and also includes circular hole one and circular hole two arranged on the gantry, the end of the second butterfly bolt extends into circular hole one, and the telescopic rod assembly is in a horizontal state; the end of the second butterfly bolt extends into circular hole two, and the telescopic rod assembly is in a vertical state.

[0018] By adopting the above technical solution, when it is necessary to use the telescopic auxiliary adjusting rod mechanism to adjust the position of the workpiece, the telescopic rod assembly is rotated to a horizontal state, and then the second butterfly bolt is rotated to extend into the circular hole one for limiting the position. When the telescopic auxiliary adjusting rod mechanism has completed the position adjustment of the workpiece, the telescopic rod assembly is rotated in the opposite direction to a vertical state, and then the second butterfly bolt is rotated to extend into the circular hole two for limiting the position.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] When it is necessary to adjust the position of the workpiece on the workbench, after operating the circumferential limit assembly, the telescopic rod assembly is swung to a horizontal state, and the telescopic rod assembly is operated to drive the adjusting rod assembly on the sliding rod close to the workpiece. Finally, the adjusting rod assembly is operated to move axially. The adjusting rod assembly drives the end of the workpiece to be appropriately offset in a direction perpendicular to the movement of the workbench, so that the length or width direction of the workpiece is parallel to the movement direction of the workbench, thereby improving the processing accuracy of the gantry milling machine on the workpiece, and eliminating the need for workers to use tools to hit the workpiece multiple times to fine-tune it, thereby reducing the labor intensity of workers and improving the convenience of operation.

[0032] It should be noted that these drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

One end of the telescopic rod assembly 60 is connected to a sleeve 11, a sliding rod 12 is provided in the sleeve 11, and an adjustment rod assembly 70 is respectively passed through the two ends of the sliding rod 12.

[0035] It also includes a circumferential limit assembly 80, which is suitable for preventing the telescopic rod assembly 60 from swinging in the horizontal and vertical directions; the circumferential limit assembly 80 includes a support seat 81 and a second butterfly bolt 82 spirally penetrated on the support seat 81, and also includes a circular hole 1 83 and a circular hole 2 84 arranged on the gantry 3, the end of the second butterfly bolt 82 extends into the circular hole 1 83, the telescopic rod assembly 60 is in a horizontal state, the end of the second butterfly bolt 82 extends into the circular hole 2 84, and the telescopic rod assembly 60 is in a vertical state; when it is necessary to use the telescopic auxiliary adjusting rod mechanism to adjust the position of the workpiece, after rotating the telescopic rod assembly 60 to the horizontal state, the second butterfly bolt 82 is rotated to extend into the circular hole 1 83 for limiting the position. When the telescopic auxiliary adjusting rod mechanism has completed the position adjustment of the workpiece, the telescopic rod assembly 60 is rotated in the opposite direction to the vertical state, and the second butterfly bolt 82 is rotated to extend into the circular hole 2 84 for limiting the position.

[0036] The rotating shaft seat 50 includes a fixed seat 51 and a support shaft 52 that passes through the fixed seat 51 and is rotatably connected thereto. The fixed seat 51 is connected to the gantry 3, and one end of the support shaft 52 is connected to the telescopic rod assembly 60. Since the support shaft 52 is rotatably connected to the fixed seat 51, it is convenient for the telescopic rod assembly 60 to swing. When the position of the workpiece is adjusted using the adjusting rod assembly 70, the circumferential limit assembly 80 is operated to swing the telescopic rod assembly 60 to a vertical state, thereby preventing the telescopic auxiliary adjusting rod mechanism from affecting the worker's operation of the gantry milling machine.

One end of the threaded adjusting rod 72 is connected to a handle 73, and the other end is connected to a wear-resistant plastic block 74; rotating the handle 73 drives the threaded adjusting rod 72 to rotate, and the threaded adjusting rod 72 produces axial movement. The threaded adjusting rod 72 pushes the workpiece through the wear-resistant plastic block 74 for fine-tuning. The structure is simple and the operation is convenient.

[0040] The implementation principle of this embodiment is: when in use, a crane is used to lift a larger workpiece onto the workbench 2. When the position of the workpiece needs to be adjusted, the circumferential limit assembly 80 is operated to rotate the telescopic rod assembly 60 to a horizontal state. After operating the telescopic rod assembly 60 to drive the sleeve 11 to move appropriately, the adjusting rod assemblies 70 at both ends of the sliding rod 12 are close to the side of the workpiece. Next, the adjusting rod assembly 70 is operated to move axially.
