Description

Technical Field

[0001] This utility model relates to the field of five-axis engraving machines, and in particular to a five-axis engraving machine with a limiting function. Background Technology

[0002] In modern manufacturing, CNC engraving machines, as an important branch of CNC machine tools, play an irreplaceable role in the fine processing of metal and non-metal materials due to their high precision and efficiency. Metal engraving machines can precisely process a variety of hard materials, including stainless steel plates, iron plates, silicon wafers, ceramic sheets, titanium alloys, epoxy materials, A3 steel, and even diamond, through non-contact laser cutting and drilling technology, greatly expanding the application range and processing precision of material processing.

[0003] However, in specific applications, such as the processing of hollow cylindrical steel, traditional five-axis CNC engraving machines face significant limitations. Existing five-axis CNC engraving machines often lack flexible positioning mechanisms for hollow cylindrical steel of different diameters. This makes it difficult to achieve stable and precise workpiece positioning during processing, thus affecting processing quality and efficiency. Specifically, due to the lack of adjustable positioning devices, operators need to frequently change or adjust fixtures to accommodate workpieces of different sizes, increasing operational complexity and potentially leading to positioning errors due to human factors, thus affecting processing accuracy. Furthermore, fixed positioning methods limit the equipment's adaptability to diverse processing needs, reducing the overall flexibility and competitiveness of the production line.

[0004] Therefore, there is a need to provide a five-axis engraving machine with a limit function. Utility Model Content

[0005] To overcome the drawback of not being able to limit the movement of hollow cylindrical steel of different diameters, this utility model provides a five-axis precision engraving machine with a limiting function.

[0006] A five-axis engraving machine with a limiting function includes a mounting frame, a controller, a closed door, an electric slide rail one, an electric slide rail two, the engraving machine body, an electric slide rail three, a slide base, a fixing frame, and a limiting rod. The controller is installed on the upper left side of the mounting frame. The closed door is rotatably provided on the front side of the mounting frame. Electric slide rail one is installed on the upper rear side of the mounting frame. Electric slide rail two is slidably installed on electric slide rail one. The engraving machine body is slidably installed on electric slide rail two. Electric slide rail three is symmetrically installed at the bottom of the mounting frame. Slider blocks are slidably installed on the top left and right sides of the two electric slide rail threes. A slide base is installed between the tops of the two sliders on the left and right sides. A fixing frame is provided on each slide base. A limiting rod is symmetrically slidably provided on the upper part of each fixing frame. The machine also includes an adjustment component. An adjustment component is provided on the upper right side of the fixing frame on the right side.

[0007] Preferably, the adjustment assembly includes a dual-axis motor, a screw, a connecting frame, and an adjustment plate. The dual-axis motor is located on the upper right side of the fixed frame on the right side. The output end of the dual-axis motor is provided with a screw. The front and rear ends of the screw are both provided with connecting frames via threads. The upper part of the connecting frame is connected to the outer end of the adjacent limit rod. An adjustment plate is provided between the bottom of the two front connecting frames and between the bottom of the two rear connecting frames.

[0008] Preferably, the mounting frame also includes a fixed base, a motor, a second screw, and a support frame. The fixed base is located at the bottom center of the mounting frame, the motor is mounted on the right side of the fixed base, the second screw is located at the output end of the motor, and the support frame is located at the upper end of the second screw via a thread.

[0009] Preferably, the support frame is positioned between the two adjustment plates.

[0010] Preferably, the top of the support frame is padded.

[0011] As a preferred option, the closed door is equipped with a glass window.

[0012] The beneficial effects and significant advancements of this utility model are as follows:

[0013] This invention utilizes a dual-axis motor to drive a screw to rotate, which in turn drives a connecting frame to move back and forth via a threaded connection. This, in turn, causes the limiting rod and adjusting plate to move synchronously. This design allows for precise adjustment of the front and rear positions of the limiting rod based on the actual diameter of the hollow cylindrical steel, ensuring that the limiting rod can reliably support the inner side of the hollow cylindrical steel and achieve precise positioning.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example: A five-axis engraving machine with a limiting function, such as Figures 1-7As shown, the machine includes a mounting frame 1, a controller 101, a closed door 2, an electric slide rail 1 3, an electric slide rail 2 4, the engraving machine body 5, an electric slide rail 3 6, a slide base 7, a fixing frame 8, a limit rod 9, a dual-axis motor 10, a screw 1 11, a connecting frame 12, an adjusting plate 13, a fixing seat 14, a motor 15, a screw 2 16, and a support frame 17. The mounting frame 1 serves as the main frame structure of the entire engraving machine, providing installation support and space for other components, ensuring the overall stability and safety of the equipment. The controller 101 is installed on the upper left side of the mounting frame 1. A closed door 2 is rotatably installed on the front side of the mounting frame 1, with a glass window for easy observation of the interior of the mounting frame 1. The closed door 2 serves to close the mounting frame 1 and is closed when the engraving machine is working. To prevent dust and debris from splashing out during processing, an electric slide rail 3 is horizontally mounted on the upper rear side of the mounting frame 1. The controller 101 is electrically connected to the electric slide rail 3. An electric slide rail 4 is vertically mounted on the electric slide rail 3 via a slider. The controller 101 is also electrically connected to the electric slide rail 4. The engraving machine body 5 is vertically mounted on the electric slide rail 4 via a slider. The engraving machine body 5 is the core component for engraving, possessing five-axis motion capabilities. It can perform complex-shaped engraving and milling operations on workpieces, achieving high-precision processing requirements. The slider on the electric slide rail 3 drives the electric slide rail 4 and the engraving machine body 5 to move left and right in the horizontal direction, thus adjusting the position of the engraving machine body 5 in the left and right directions. The slider on the electric slide rail 2 4 drives the engraving machine body 5 to move up and down in the vertical direction, thereby adjusting the position of the engraving machine body 5 in the vertical direction. The controller 101 is electrically connected to the engraving machine body 5. Electric slide rail 3 6 is symmetrically installed horizontally at the bottom of the mounting frame 1. The controller 101 is electrically connected to the electric slide rail 3 6. Sliders are slidably installed on the top left and right sides of the two electric slide rail 3 6. A slide seat 7 is installed between the tops of the two sliders on the left side and between the tops of the two sliders on the right side. A fixing frame 8 is vertically connected to the top of each slide seat 7. Limiting rods 9 are symmetrically slidably connected to the upper part of each fixing frame 8. The limiting rods 9 are used to support the inner side of the cylindrical hollow steel and provide support for the cylindrical hollow steel. The sliding of the slider on the electric slide rail 6 drives the slide block 7 and the fixed frame 8 to move left and right in the horizontal direction, thereby adjusting the position of the limit rod 9. A dual-axis motor 10 is longitudinally mounted on the upper right side of the fixed frame 8 on the right side. The output shaft of the dual-axis motor 10 is connected to a screw 11. The front and rear ends of the screw 11 are threaded to connecting frames 12. The upper part of each connecting frame 12 is connected to the outer end of the adjacent limit rod 9. An adjusting plate 13 is connected between the bottom of the two connecting frames 12 on the front side and between the bottom of the two connecting frames 12 on the rear side. The adjusting plate 13 is used to support the bottom of the cylindrical hollow steel. A fixed seat 14 is vertically connected to the center of the bottom inside the mounting frame 1. A motor 15 is vertically mounted on the right side of the fixed seat 14.The output shaft of motor 15 is connected to screw 16. The upper end of screw 16 is threadedly connected to a support frame 17. A soft pad is placed on top of the support frame 17 to prevent damage to the hollow cylindrical steel. The support frame 17 is located between two adjusting plates 13 and is used to support the hollow cylindrical steel, increasing its support.

[0024] When using the five-axis CNC engraving machine, connect it to a suitable power source, ensuring a stable and normal power connection. Then, manually rotate the closed door 2 to open it, providing ample operating space for placing the workpiece. Place the hollow cylindrical steel to be processed stably on the support frame 17, carefully checking to ensure it is stable and prevent tipping during subsequent operations. Start the motor 15 via the controller 101. The motor 15 drives the screw 16 to rotate, causing the support frame 17 to move up and down along the screw 16, adjusting the hollow cylindrical steel to a suitable height for subsequent limiting and processing operations. Based on the length of the hollow cylindrical steel, control the slider on the electric slide rail 6 via the controller 101, causing the slide block 7 and the fixed frame 8 to move left and right, ensuring the distance between the two fixed frames 8 is slightly greater than the length of the hollow cylindrical steel, providing sufficient space for adjusting the limit rod 9. Start the dual-axis motor 10; the output shaft of the dual-axis motor 10 drives the screw 11 to rotate. Since the screw 11 and the connecting frame 12 are connected by threads, the connecting frame 12 moves back and forth under the rotation of the screw 11, which in turn drives the limiting rod 9 and the adjusting plate 13 to move back and forth. This allows for precise adjustment of the front and rear position of the limiting rod 9 according to the diameter of the hollow cylindrical steel, ensuring that the limiting rod 9 reliably supports the inner side of the hollow cylindrical steel and limits its movement. Simultaneously, the adjusting plate 13 firmly supports the bottom of the hollow cylindrical steel, ensuring that it does not move back and forth during processing.

[0025] The controller 101 controls the movement of the slider on the electric slide rail 3, which in turn drives the electric slide rail 4 and the engraving machine body 5 to move left and right in the horizontal direction, accurately adjusting the engraving machine body 5 to the left and right positions corresponding to the processing position of the cylindrical hollow steel.

[0026] Control the movement of the slider on the electric slide rail 4 to drive the engraving machine body 5 to move up and down in the vertical direction, adjust the engraving machine body 5 to a suitable processing height, so that the processing tool of the engraving machine body 5 can accurately process the cylindrical hollow steel.

[0027] Set the processing parameters of the engraving machine body 5 on the controller 101, such as processing speed, processing depth, tool path, etc., and make reasonable settings according to the material of the cylindrical hollow steel and processing requirements. After confirming that all parameters are set correctly, start the processing program of the engraving machine body 5 on the controller 101, and the engraving machine body 5 will begin to perform engraving processing on the cylindrical hollow steel according to the set parameters.

[0028] Once the processing program is complete, the engraving machine body 5 automatically stops working, and the operator confirms the completion of processing via the controller 101. The operator then manually rotates the closed door 2 to open it, and carefully removes the processed hollow cylindrical steel from the support frame 17 and the adjusting plate 13. Finally, the operator turns off the power switch of the controller 101, disconnecting the equipment from the power supply, thus completing the processing operation.

[0029] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
