Description

Technical Field

[0001] This utility model relates to the field of tool magazine technology, specifically a disc tool magazine. Background Technology

[0002] In some small machining tools, linear tool magazines are often used. Linear tool magazines require tools to be arranged in a straight line, occupying a long linear space. The space requirement is even greater when there are a large number of tools. Tool changing in linear tool magazines depends on the movement of tools in a straight line, and tool selection and changing takes a long time. Utility Model Content

[0003] The purpose of this invention is to provide a disc tool magazine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a disc-shaped tool magazine, comprising:

[0005] Mounting bracket;

[0006] A servo motor is fixedly connected inside the mounting bracket, and a rotating plate is fixedly connected to the output end of the servo motor.

[0007] A knife clip is a chuck with an opening at one end. An arc-shaped notch is provided in the middle of the knife clip and inside the opening, which is used to load and unload knives. When subjected to external squeezing force, the local area undergoes elastic deformation.

[0008] The handle is placed inside the opening of the tool holder;

[0009] The position detection unit is located below the rotating plate and is used to detect the rotation angle of the rotating plate and the position of the tool holder.

[0010] Preferably, a protective shell is fixedly connected to the top of the mounting bracket, and the protective shell is a semi-circular structure with an opening at the top.

[0011] Preferably, the position detection unit includes a photoelectric sensor and a proximity switch. A mounting plate is fixedly connected to the top of the servo motor, and the photoelectric sensor is horizontally fixed to the middle of the mounting plate for detecting whether a tool holder is present on the tool holder.

[0012] Preferably, the proximity switch is vertically fixed to one side of the mounting plate and is used to detect whether the rotating plate has been reset to the origin.

[0013] Preferably, a limiting protrusion is provided in the opening at one end of the blade holder to limit the movement of the blade handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: A servo motor precisely controls the rotation angle and speed to drive the rotating plate. Combined with a position detection unit (photoelectric sensor and proximity switch), the rotation angle of the rotating plate and the position of the tool holder are detected. If the tool holder does not reach the correct position, the controller adjusts the rotation angle until the tool holder accurately reaches the target position, achieving high precision in tool replacement and positioning. An arc-shaped notch is provided in the opening at one end of the tool holder. When the tool holder is placed inside the opening, a localized area of ​​the tool holder undergoes elastic deformation under external force. The arc-shaped notch design makes the tool holder more firmly fixed in the tool holder, while reducing the impact of vibration or imbalance on tool operation. A limiting protrusion is provided in the opening at one end of the tool holder, which cooperates with the annular groove in the middle of the tool holder to provide physical positioning and limiting for the tool holder, preventing the tool holder from shifting or falling off during clamping with the tool holder, thus ensuring the stability of tool clamping.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , 2As shown in Figures 3 and 4, this utility model provides a technical solution: a disc tool magazine, comprising: a mounting bracket 1; a servo motor 2 fixedly connected inside the mounting bracket 1, the output end of the servo motor 2 connected to a reducer, the output end of the reducer being connected to a rotating shaft via a coupling, the end of the rotating shaft being fixedly connected to a rotating plate 4, the rotating plate 4 being driven by precisely controlling the rotation angle and speed, the rotating plate 4 rotating to realize tool replacement or positioning; a tool holder 5 being a chuck with an opening at one end, the middle of the tool holder 5 having an arc-shaped notch 6 located inside the opening, used for loading and unloading tools, where localized areas undergo elastic deformation under the action of external pressure, the arc-shaped notch 6 being designed in the middle of the opening. This design allows the tool holder to undergo a certain degree of elastic deformation under external force, thereby more firmly fixing the tool and reducing the impact of vibration or imbalance on tool operation; a tool holder 11 placed inside the opening of the tool holder 5; a position detection unit placed below the rotating plate 4, used to detect the presence of the tool holder 11 and to read the number by identifying the optical mark on the tool holder 11.

[0022] It should be noted that in this embodiment, both the servo motor 2 and the position detection unit are electrically connected to the PLC controller. The servo motor drives the rotating plate 4 to rotate, and the movement of the rotating plate 4 can change the position of the tool holder 5 and the tool shank 11 to perform tool replacement or adjustment operations. When the rotating plate 4 rotates to a specified angle, the spindle moves above the tool holder 5 to pick up the tool rectangularly and slides it horizontally out from one end of the tool holder 5. When placing the tool, the spindle slides the tool horizontally into the tool holder 5 from one end, and fixes the tool shank through the arc-shaped notch 6. The elastic deformation function of the chuck ensures that the tool is firmly fixed. The position detection unit monitors the angle of the rotating plate and the position of the tool shank to ensure that the tool shank reaches the preset position. If the tool shank does not reach the correct position, the controller will adjust the rotation angle until the tool shank accurately reaches the target position.

[0023] It should be noted that a protective shell 3 is fixedly connected to the top of the mounting bracket 1. The protective shell 3 is a semi-circular structure with an opening at the top.

[0024] It should be noted that in this embodiment, the protective shell 3, fixed to the top of the mounting bracket 1, ensures the safety of the tool operating system. When the tool magazine rotating plate starts working, the protective shell covers the rotating part with its semi-circular structure, while allowing the tool to enter or exit the system through openings. During equipment operation, the protective shell protects personnel from direct contact with mechanical parts.

[0025] It should be noted that the position detection unit includes a photoelectric sensor 9 and a proximity switch 10. The top of the servo motor 2 is fixedly connected to a mounting plate 8. The photoelectric sensor 9 is horizontally fixed to the middle of the mounting plate 8 and is used to detect whether there is a tool holder 11 on the tool holder 5. The proximity switch 10 is vertically fixed to one side of the mounting plate 8 and is used to detect whether the rotating plate has been reset to the origin.

[0026] It should be noted that in this embodiment, the photoelectric sensor 9 is used to detect whether there is a tool holder 11 on the tool holder 5. A metal block that cooperates with the proximity switch 10 is fixed at the reset point of the rotating plate 4. The photoelectric sensor determines whether the rotating plate 4 has rotated to the reset point by detecting the position of the metal block, and provides feedback for the movement of the servo motor 2 or the rotating plate 4. After determining that the rotating plate 4 has reset to the origin, when the tool grabbing action is performed, the servo motor drives the rotating plate 4 to a specified angle through the reducer and coupling, so that the corresponding tool holder moves to the position that cooperates with the spindle. At the same time, when the photoelectric sensor 9 detects that there is no tool holder 11 on the tool holder 5, the tool grabbing action will not be performed. When the photoelectric sensor 9 detects that there is a tool holder 11 on the tool holder 5, it can perform the tool grabbing action, but it will not perform the tool unloading action if there is a tool holder, so as to ensure that when the spindle changes the tool grabbing action, the wrong tool will be grabbed or the tool will collide.

[0027] It should be noted that a limiting protrusion 7 is provided in the opening at one end of the tool holder 5 to limit the tool holder 11.

[0028] It should be noted that in this embodiment, the limiting protrusion 7 is a structure installed inside the opening at one end of the tool holder 5. Its main function is to provide physical positioning and limiting for the tool handle 11. The protrusion cooperates with the annular groove in the middle of the tool handle 11 to ensure that the tool handle will not shift during the clamping process with the tool holder 5, thus preventing it from falling off.
