Description

A worktable for an automatic cutting machine with a fixed tool magazine Technical Field

[0001] This utility model belongs to the technical field of cutting and processing equipment, and in particular relates to a worktable for an automatic cutting machine with a fixed tool magazine. Background Technology

[0002] Tool magazines are a key component of machining centers for multi-process automated machining. They automatically and quickly change between various tools according to the machining program, enabling the machining center to perform multiple operations such as milling, drilling, and tapping in a single setup. The application of tool magazines significantly improves machining efficiency and flexibility, reduces human intervention and downtime, and helps improve machining accuracy, consistency, and automation levels. It is an indispensable core functional module for achieving efficient and high-precision CNC machining.

[0003] Currently, machining centers specifically designed for cutting operations are relatively scarce in industrial applications. Most existing machining centers focus on general milling and drilling processes, and their tool magazines are typically side-mounted, primarily serving small, standardized tools (such as milling cutters, drills, and taps). However, for saw blades commonly used in cutting operations, especially large-diameter, thick, and uniquely shaped circular saw blades, these traditional tool magazines have significant shortcomings in terms of spatial layout, clamping methods, and tool change path design. On the one hand, the limited space of side-mounted tool magazines cannot effectively store large-sized tools; on the other hand, the weight and shape of large saw blades place higher demands on the stability and safety of the tool changing mechanism, making it difficult for existing mechanisms to achieve efficient and smooth tool changing operations. Therefore, existing technologies for machining center tool magazine design for cutting operations suffer from structural incompatibility and poor adaptability, necessitating the development of a tool changing system suitable for large-sized cutting tools to meet the demands of modern cutting processes for automation, high efficiency, and high flexibility. Summary of the Invention

[0004] To address the problem that existing tool magazine designs cannot meet the requirements for storing and efficiently changing cutting tools, resulting in poor processing adaptability and low automation, this utility model provides a worktable for an automatic cutting machine with a fixed tool magazine.

[0005] This utility model relates to an automatic cutting machine workbench with a fixed tool magazine, characterized in that it includes a hanging frame and a movable frame. The movable frame is installed on the lower part of the hanging frame via a horizontal movement drive mechanism, which drives the movable frame to move horizontally in a straight line. N clamping units are installed at intervals along the horizontal straight line on the movable frame, and the distribution direction of the clamping units is perpendicular to the movement direction of the movable frame.

[0006] In the above technical solution, preferably, the clamping unit includes an arc-shaped bayonet and an electromagnetic locking pin disposed on the side of the arc-shaped bayonet. The electromagnetic locking pin has a pin tongue that extends radially into the arc-shaped bayonet and is used to clamp the handle of the cutter head inside the arc-shaped bayonet.

[0007] In the above technical solution, preferably, the hanging bracket forms a box structure with an opening at the bottom, the movable frame, the horizontal movement drive mechanism, and the clamping unit are located inside the box structure, the bottom of the box structure has a horizontally extending opening, the hanging bracket is equipped with an arc-shaped rotating door through a door hinge, the arc-shaped rotating door rotates around the door hinge to realize the closing and opening of the opening, and a door drive assembly for driving the arc-shaped rotating door to flip is installed inside the box structure.

[0008] In the above technical solution, preferably, the door drive assembly includes a miniature cylinder and a crank, and the miniature cylinder drives the arc-shaped revolving door to rotate through the crank connected to the arc-shaped revolving door.

[0009] The worktable for an automatic cutting machine with a fixed tool magazine proposed in this utility model has significant advantages and technical effects.

[0010] Firstly, the worktable, through its hanging and movable frame design, can be suspended and adapted to the underutilized space above the cutting machining center, helping to optimize the overall layout of the machining center. This space optimization makes the overall structure of the machining center more compact, avoiding the disadvantage of traditional tool magazines occupying a large amount of space.

[0011] The worktable, via a horizontally moving drive mechanism and a horizontally movable, laterally arranged tool magazine, can be positioned closer to the cutting spindle. This design significantly shortens the tool change path and time from the tool magazine to the spindle, thereby improving tool change efficiency, reducing equipment idle time, and significantly enhancing machining efficiency.

[0012] The gripping units on the worktable are evenly distributed horizontally along the moving frame and perpendicular to the frame's direction of movement. This design ensures excellent tool stability during loading and unloading, preventing accuracy errors caused by tool wobbling or shaking, thus guaranteeing high precision and stability during tool changing. This is particularly important for cutting tasks requiring high-precision machining, effectively improving the quality of the final product.

[0013] A high degree of automation is a major advantage of this worktable. Through the design of an automatically moving tool magazine, combined with the automated coordination between the cutting spindle and the tool magazine, the worktable reduces manual intervention and improves the automation level of the production line. This design not only reduces errors and workload caused by manual operation but also provides a reliable guarantee for efficient and continuous production.

[0014] In summary, this automatic cutting machine worktable with a fixed tool magazine can improve space utilization and tool changing efficiency, effectively enhancing the overall performance of the cutting and machining center and providing an efficient, flexible, and precise solution for modern cutting and machining.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0021] To address the shortcomings of existing tool magazine designs in meeting the requirements for tool storage and efficient tool changing, this invention provides a worktable for an automatic cutting machine with a fixed tool magazine. To further illustrate the structure of this invention, a detailed description is provided below in conjunction with the accompanying drawings:

[0022] Please refer to Figures 1-5. An automatic cutting machine workbench with a fixed tool magazine includes a hanging frame 1 and a movable frame 2. The movable frame is mounted on the lower part of the hanging frame via a horizontal movement drive mechanism. The horizontal movement drive mechanism drives the movable frame to move horizontally in a straight line. N clamping units are installed at intervals along another horizontal straight line direction on the movable frame. The two horizontal straight lines are perpendicular to each other.

[0023] In this embodiment, specifically, a linear slide rail 3 is provided at the bottom of the hanger, which cooperates with the movable frame to form a guide. The horizontal movement drive mechanism 4 is a hydraulic cylinder, with the rear end of the hydraulic cylinder hinged to the lower part of the hanger via a shaft, and the front piston rod connected to the movable frame, used to drive the movable frame to move horizontally and linearly under the guidance of the linear slide rail.

[0024] The clamping unit includes an arc-shaped bayonet 5 and an electromagnetic locking pin 6 located on the side of the arc-shaped bayonet. The electromagnetic locking pin has a pin tongue that extends radially into the arc-shaped bayonet to clamp the tool holder of the tool head 10 inside the arc-shaped bayonet. The arc dimension of each arc-shaped bayonet matches the outer diameter of the locking groove of the tool holder of the tool head equipped in the tool magazine to ensure stable clamping. The front end of the pin tongue of the electromagnetic locking pin has a conical or rounded structure to facilitate guiding the tool holder to position during automatic loading.

[0025] The hanging bracket forms a rectangular box structure with an open bottom. The movable frame, horizontal movement drive mechanism, and clamping unit are located inside the box structure, which has a horizontally extending opening at the bottom. An arc-shaped revolving door 7 is mounted on the hanging bracket via a door hinge. The arc-shaped revolving door rotates around the door hinge to close and open the opening.

[0026] The inner side of the housing houses a door drive assembly that drives the curved revolving door to rotate. The curved revolving door is constructed of aluminum plate or engineering plastic, offering advantages in both lightweight design and strength. Both ends of the door hinge are connected to the hanger via bearing-supported pivot seats, ensuring smooth rotation. The door drive assembly includes a miniature cylinder 8, which drives the curved revolving door to rotate via a crank 9 connected to the curved revolving door. Specifically, the rear of the miniature cylinder is hinged to the inner wall of the hanger, the piston rod of the miniature cylinder is hinged to the crank, and the crank connects to the portion of the curved revolving door that fits onto the door hinge, thus enabling the miniature cylinder to drive the curved revolving door to rotate and open / close.

[0027] Traditional tool magazine worktables often employ an open structure, leaving them exposed to the external environment and highly susceptible to contaminants such as cutting debris and dust. This can negatively impact the reliability of tool holder clamping and the sensitivity of the electromagnetic lock. In contrast, the automatic cutting machine worktable with a fixed tool magazine in this solution is suspended above the workspace, maximizing its proximity to the cutting spindle for easy tool changing. When not changing tools, the open design can be sealed to effectively prevent foreign objects from entering the tool magazine. This protection is not achieved through a complex sealing system, but rather through a controllable opening / closing rotary door combined with the housing structure. This not only improves cleanliness but also reduces system complexity, achieving a balance between simple design and high reliability. The curved rotary door not only provides a sealing function but also acts as a safety barrier during tool changing when flipped. If the cutting spindle assembly is not precisely aligned with the tool holder or the tool holder is not fully inserted into the clamping unit, and an accidental detachment occurs, the open rotary door acts as a buffer and physical barrier, preventing the tool head from falling and affecting the workspace. This is difficult to achieve in traditional open tool magazine systems. In this structure, the presence of the rotating door cleverly establishes a new functional bridge between "sealed dust prevention" and "safety and anti-detachment", producing an unexpected composite technical effect.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
