Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, specifically to a rotary cylinder mounting structure for a tool magazine door switch. Background Technology

[0002] The tool magazine door of a CNC engraving machine is mounted on the gantry frame, primarily to prevent cutting fluid, chips, and foreign objects from entering the tool magazine. The existing installation structure of the tool magazine door on a CNC engraving machine is as follows: Figure 1 As shown, a gantry 100 is mounted on the machine frame, a Y-axis linear module 200 is mounted on the machine frame and located below the gantry 100, and a worktable 300 is mounted on the Y-axis linear module 200. A door frame 400 is mounted on the gantry 100, and a flip-up tool magazine door 500 is mounted at the bottom of the door frame 400. The tool magazine door 500 is controlled by two obliquely positioned push cylinders 600. In actual operation, when a tool change is required, the push cylinders 600 push the tool magazine door 500 upwards at an angle, opening the door. The tool magazine passes through the gantry 100 and moves to the tool changing position for tool changing. After the tool change is completed, the tool magazine returns to its original position, and then the push cylinders 600 pull the tool magazine door 500 back to its original position. The tool magazine door 500 separates the worktable from the tool magazine to prevent cutting fluid, chips, and foreign objects from entering the tool magazine during machining. However, the installation structure of the aforementioned tool magazine door 500 has the following main defects: (1) The cylinder-driven oblique push-pull switch of the tool magazine door does not operate smoothly, the switch is not fully engaged, and the operation is abnormal. (2) The cylinder-driven oblique push-pull structure has no self-locking device. In a humid working environment, the cylinder is easily damaged, causing the push-pull switch of the tool magazine door to fail, ultimately leading to a door collision failure of the workbench or tool magazine. (3) The cost of the cylinder-driven oblique push-pull structure is higher than that of the rotary cylinder structure. (4) The cylinder-driven oblique push-pull structure occupies a larger installation area and is prone to motion interference. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a rotary cylinder mounting structure for a tool magazine door switch. The single rotary cylinder design not only saves installation space and reduces equipment costs, but also reduces the likelihood of malfunctions and ensures smooth operation of the tool magazine door switch.

[0004] To achieve the above technical solution, this utility model provides a rotary cylinder mounting structure for a knife magazine door switch, comprising: a door frame mounted on a gantry frame, a knife magazine door mounted at the bottom of the door frame, the top of the knife magazine door being connected to the door frame via a hinge, a fixed bracket mounted on the end edge of the door frame, a mounting flange of the rotary cylinder being connected and fixed to the fixed bracket, and the rotating shaft of the rotary cylinder being connected to the shaft hole of the knife magazine door through the through hole of the fixed bracket, thereby driving the knife magazine door to swing and switch around the hinge.

[0005] In the above technical solution, during actual operation, when the tool magazine moves from the rear to the front through the gantry, the rotary cylinder drives the tool magazine door to rotate and open, allowing the tool magazine to move to the tool changing position. After the tool change is completed, when the tool magazine moves back from the tool changing position to its original position, the rotary cylinder drives the tool magazine door to rotate and close, preventing cutting fluid, chips, and foreign objects from entering the tool magazine during the machining process.

[0006] Preferably, the tool magazine door is equipped with multiple proximity sensors arranged side by side at intervals along the horizontal direction to sense the distance between the tool magazine and the tool magazine door. Once the proximity sensors detect that the tool magazine is approaching, a signal can be sent immediately to drive the tool magazine door to rotate via a rotary cylinder.

[0007] Preferably, a water spray pipe is installed on the tool magazine door to facilitate cleaning of the workbench during subsequent processing.

[0008] The advantages of the rotary cylinder mounting structure for a tool magazine door switch provided by this utility model are as follows: This rotary cylinder mounting structure for a tool magazine door switch solves the technical problems of unsmooth operation, incomplete opening and closing, and abnormal operation of the tool magazine door when using a cylinder-driven oblique push-pull switch; the lack of a self-locking device in the cylinder-driven oblique push-pull structure makes the cylinder prone to damage in a humid working environment, leading to the failure of the push-pull switch and ultimately causing the worktable or tool magazine to collide with the door. Furthermore, the single rotary cylinder design not only saves installation space and reduces equipment costs, but also reduces the likelihood of malfunctions, ensuring smooth operation of the tool magazine door. In actual operation, when the tool magazine moves from rear to front through the gantry, the rotary cylinder drives the tool magazine door to rotate and open, allowing the tool magazine to move to the tool changing position. After tool changing, when the tool magazine moves back from the tool changing position to its original position, the rotary cylinder drives the tool magazine door to rotate and close, preventing cutting fluid, chips, and foreign objects from entering the tool magazine during machining.

[0016] Example: A rotary cylinder mounting structure for a knife magazine door switch.

[0017] Reference Figures 1 to 5 As shown, a rotary cylinder mounting structure for a tool magazine door switch includes: a door frame 1 mounted on a gantry frame; a tool magazine door 3 mounted at the bottom of the door frame 1; the top of the tool magazine door 3 connected to the door frame 1 via a hinge 2, allowing the tool magazine door 3 to rotate relative to the door frame 1; a fixed bracket 6 mounted on one end of the door frame 1; a mounting flange of a rotary cylinder 7 connected and fixed to the fixed bracket 6; and the other right-angled side of the fixed bracket 6 fixed to the door frame 1. The rotating shaft of the rotary cylinder 7 is connected to the shaft hole of the tool magazine door 3 through a through hole in the fixed bracket 6, allowing the rotary cylinder 7 to drive the tool magazine door 3 to swing and switch around the hinge 2. Multiple proximity sensors 5, arranged laterally and spaced apart, are mounted on the tool magazine door 3 to sense the distance between the tool magazine and the tool magazine door 3. Once the proximity sensor 5 detects the tool magazine approaching, it immediately sends a signal to drive the rotary cylinder 3 to rotate the tool magazine door 3. A water spray pipe 4 is mounted on the tool magazine door 3 to facilitate cleaning of the workbench during subsequent processing.

[0018] The rotary cylinder mounting structure of this tool magazine door switch solves the technical problems of unsmooth operation, incomplete opening and closing, and abnormal operation of the cylinder-driven oblique push-pull switch for the tool magazine door 3; the lack of a self-locking device in the cylinder-driven oblique push-pull structure makes the cylinder prone to damage in long-term humid working environments, leading to the failure of the push-pull switch for the tool magazine door and ultimately causing the worktable or tool magazine to collide with the door. Furthermore, the single rotary cylinder 7 design not only saves installation space and reduces equipment costs but also reduces the likelihood of failure, ensuring smooth operation of the tool magazine door. In actual operation, when the tool magazine moves from rear to front through the gantry, the rotary cylinder 7 drives the tool magazine door 3 to rotate and open, allowing the tool magazine to move to the tool changing position. After tool changing, when the tool magazine moves back from the tool changing position to its original position, the rotary cylinder 7 drives the tool magazine door 3 to rotate and close, preventing cutting fluid, chips, and foreign objects from entering the tool magazine during machining.
