Description

Technical Field

[0001] This utility model relates to the field of tool magazine technology, and in particular to a tower-type rotary tool magazine for EDM machines. Background Technology

[0002] A turret-type rotary tool magazine, as the name suggests, has tools fixed on a turret, and the selection and exchange of different tools is achieved by rotating the turret. This type of tool magazine is typically used in turning centers or electrical discharge machining (EDM) machines to provide fast and accurate tool changing services. Current EDM turret-type rotary tool magazines usually use a motor-driven rotating rod to rotate the tool magazine and tools, allowing a specified tool to be rotated to a designated position for tool changing. However, the tool capacity of current turret-type rotary tool magazines may be limited, meaning the machine tool may not be able to accommodate enough tools to meet the needs of complex machining tasks, thus reducing machining efficiency and flexibility. Utility Model Content

[0003] This invention provides a tower-type rotary tool magazine for EDM machines, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tower-type rotary tool magazine for an EDM machine tool includes a motor, the output end of which is connected to a rotating rod, and a tower-type rotary body is mounted on the surface of the rotating rod. A first tool holder is mounted on the surface of the tower-type rotary body, and a first tool is mounted inside the first tool holder.

[0006] A fixing plate is mounted on the surface of the rotating rod, and multiple support rods are equidistantly hinged to the surface of the fixing plate in a ring. A second blade clamp is mounted on one end of each support rod, and a second blade is provided inside the second blade clamp.

[0007] The rotating rod is movably connected to an annular plate, and the top of the annular plate is provided with partitions at equal intervals. A movable shaft is connected to one side of the partition, and a connecting rod connected to the bottom end of the support rod is connected to the surface of the movable shaft.

[0008] The above structure facilitates the operation of the cylinder, allowing the annular plate to move the connecting rod, support rod, second tool holder, and second tool, so that the second tool holder and second tool can be unfolded to store more tools.

[0009] The first and second cutting tools are staggered.

[0010] The above structure ensures that when the second tool holder and the second tool are fully extended, the second tool and the second tool holder will not affect the first tool and the first tool holder.

[0011] The bottom ends of the connecting rod and the support rod are hinged.

[0012] The above structure allows the support rod, which is hinged at its top, to move when the connecting rod is in motion.

[0013] The inner wall of the annular plate is provided with connecting blocks at equal intervals in a ring. A cylinder is installed at the top of the rotating rod, and the cylinder passes through the rotating rod and is connected to the surface of the connecting block.

[0014] The above structure facilitates the movement of the connecting block, annular plate, connecting rod, and support rod by the operation of the cylinder.

[0015] The surface of the rotating rod is provided with equidistant, annular grooves for moving the connecting block.

[0016] The above structure facilitates the movement of the connecting block by the cylinder, allowing the connecting block to move in a limited manner by moving the annular plate through the moving groove.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] In this invention, the operation of the cylinder causes the annular plate to drive the connecting rod, support rod, cutting tool, and tool holder to unfold like an umbrella structure. The umbrella-structured tool magazine typically uses an inclined tool holder to effectively increase the tool capacity. This means that more tools can be stored in the same space, thereby increasing the tool selection range of the machine tool, improving processing efficiency and flexibility. At the same time, the umbrella-structured tool magazine has a compact design and can make more efficient use of space, which is especially important for machine tool environments with limited space. It helps to reduce the overall size of the machine tool or improve the internal space utilization of the machine tool. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-4 The EDM machine tool tower rotary table tool magazine includes a motor 1. The output end of the motor 1 is fitted with a rotating rod 2 that drives the tower rotary table body 3. A first tool holder 4 and a first tool 5 are mounted on the surface of the driving tower rotary table body 3. To accommodate more tools within a limited space, a fixing plate 6 is installed on the surface of the rotating rod 2. The surface of the fixing plate 6 is annularly hinged with the same number of support rods 7 as the first tool holder 4. A second tool holder 8 is mounted on the support rods 7, and a second tool 9 is installed inside the second tool holder 8. Furthermore, to… For the support rod 7, the second tool holder 8, and the second tool 9 to be properly stored, an annular plate 10 needs to be movably installed on the surface of the rotating rod 2. A partition 11 is provided at the top of the annular plate 10. The partition 11 is for installing the movable shaft 12. A connecting rod 13 is installed on the surface of the movable shaft 12. The connecting rod 13 is also connected to the bottom end of the support rod 7 through the partition 11 and the movable shaft 12. This allows the annular plate 10 to move up and down, driving the connecting rod 13 and the support rod 7 to move, so as to install more tools through the umbrella-shaped structure.

[0029] Furthermore, in order to ensure that the first tool holder 4, the first tool 5, the second tool holder 8, and the second tool 9 do not interfere with each other, the first tool holder 4, the first tool 5, the second tool holder 8, and the second tool 9 need to be staggered.

[0030] Furthermore, in order to ensure that the support rod 7 can move when the annular plate 10 moves up and down, the connecting rod 13 needs to be connected to the support rod 7 through the partition plate 11 and the movable shaft 12, so that the support rod 7 can drive the tool to move when the annular plate 10 moves.

[0031] Furthermore, in order to ensure that the annular plate 10 can move up and down normally, a cylinder 16 needs to be installed at the top of the rotating rod 2. The output end of the cylinder 16 needs to pass through the rotating rod 2 and connect to the surface of the connecting block 14 set on the inner wall of the annular plate 10. Thus, the cylinder 16 can drive the connecting block 14 and the annular plate 10 to move. At the same time, a moving groove 15 needs to be opened on the surface of the rotating rod 2 so that the connecting block 14 can pass through the moving groove 15 and connect to the inner wall of the annular plate 10, thereby driving the annular plate 10 to move.

[0032] Working principle: When the second cutter 9 is needed, the operation of the cylinder 16 can drive the connecting block 14 to move inside the moving groove 15, thereby driving the annular plate 10 to move on the surface of the rotating rod 2. This allows the annular plate 10 to drive the connecting rod 13 hinged at its top and the support rod 7 hinged to the connecting rod 13 to move, thereby allowing the support rod 7 to flip and move on one side of the fixed plate 6, so that the second cutter clamp 8 and the second cutter 9 at one end of the support rod 7 can be flipped to a horizontal position. With the operation of the motor 1, the designated second cutter 9 can be rotated to one side of the robotic arm for tool replacement.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
