Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a rotary double-sided tool magazine and CNC machine tool. Background Technology

[0002] The CNC machine tool includes a machining platform for fixing the workpiece to be machined, a robotic arm for holding cutting tools to perform machining on the workpiece, and a tool magazine for supplying cutting tools to the robotic arm.

[0003] A tool magazine typically includes a support shaft, a tool holder turntable that rotates with the support shaft, and several chucks mounted on one side of the tool holder turntable. Each chuck holds a tool of a certain specification and model. When the robotic arm needs to change to a different tool, the support shaft drives the tool holder turntable to rotate so as to provide the robotic arm with the tool to be replaced.

[0004] Traditional tool magazines are typically single-sided, meaning that a chuck is installed only on one side of the tool holder turntable, leaving the other side unused. To increase the number of tools that a single tool holder turntable can hold, a double-sided tool magazine has been developed. This involves fixing a chuck around each side of the tool holder turntable (for ease of description, the chuck on one side of the turntable is called the first chuck, and the chuck on the other side is called the second chuck), thereby doubling the number of tool heads that a single turntable can hold.

[0005] However, in order to reduce the load on the supporting shaft, the thickness of the tool holder turntable is usually small. The arrangement of a chuck on each side of the tool holder turntable results in an excessively small gap between the first and second chucks. When the robotic arm picks up the tool from the first chuck, foreign objects such as slag on the robotic arm can easily fall onto the tool in the second chuck (similarly, when the robotic arm picks up the tool from the second chuck, foreign objects such as slag on the robotic arm can easily fall onto the tool in the first chuck), affecting the subsequent machining quality of the tool in the second chuck.

[0006] Therefore, the existing double-sided tool magazine needs to be improved to solve the problem that foreign objects on the robotic arm can easily fall to the other side of the tool turret when the robotic arm is changing tools on one side of the tool turret.

[0007] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0008] One objective of this invention is to provide a rotary double-sided tool magazine and CNC machine tool, which can effectively solve the problem that when the robotic arm changes tools on one side of the tool holder turntable, foreign objects on the robotic arm are easily dropped to the other side of the tool holder turntable.

[0056] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0057] In the description of this invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present simultaneously. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

[0058] Furthermore, terms such as “long,” “short,” “inner,” and “outer” indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0059] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0060] This invention provides a rotating cover type double-sided tool magazine and a CNC machine tool having the rotating cover type double-sided tool magazine, which is suitable for machining scenarios such as drilling, milling, grinding, cutting and carving of workpieces. It can effectively solve the problem that when the robotic arm changes tools on one side of the tool holder turntable, foreign objects on the robotic arm are easy to fall to the other side of the tool holder turntable.

[0061] It should be noted that the CNC machine tool described in this invention can be a drilling machine, engraving machine, or milling machine, etc. By changing different types of cutting tools and control programs, the CNC machine tool in this invention can have different functions. This invention does not limit the specific type of CNC machine tool.

[0062] See Figure 1 In this embodiment, the CNC machine tool includes a machining platform (not shown in the figure) for fixing the workpiece to be machined, a robotic arm 100 for holding the cutting tool 200 to perform machining on the workpiece, and a rotating double-sided tool magazine for providing the cutting tool 200 to the robotic arm 100.

[0063] See Figures 2-4The rotating double-sided tool magazine includes a supporting rotating shaft 1, a tool holder turntable 2, and a cover assembly 3. Further, one side of the tool holder turntable 2 (specifically the left side in this embodiment) is provided with a plurality of first chucks 401 arranged along the circumferential surface of the tool holder turntable 2; the other side of the tool holder turntable 2 (specifically the right side in this embodiment) is provided with a plurality of second chucks 402 arranged along the circumferential surface of the tool holder turntable 2.

[0064] Understandably, by installing chucks on both sides of the tool post turntable 2, the clamping capacity of the original tool 200 can be increased to twice the original capacity, greatly expanding the selection of machining methods for workpieces by CNC machine tools.

[0065] Optionally, both the first chuck 401 and the second chuck 402 are provided with identification tags 403. For example, the identification tags 403 may be marked with information such as numbers or tool 200 model numbers, so that the operator can correctly install the tool 200 into the correct first chuck 401 or second chuck 402 when loading the tool into the chuck.

[0066] The tool holder turntable 2 is mounted on the support shaft 1 and rotates with the support shaft 1. (See also...) Figure 5 and Figure 6 The cover assembly 3 is installed on the outside of the tool holder turntable 2, and has a first tool change hole 3021 for the robotic arm 100 to pass through at a position corresponding to one side of the tool holder turntable 2, and a second tool change hole 3022 for the robotic arm 100 to pass through at a position corresponding to the other side of the tool holder turntable 2. The first tool change hole 3021 and the second tool change hole 3022 are offset, that is, the first tool change hole 3021 and the second tool change hole 3022 are arranged in an inclined direction, so that the cover assembly 3 has a first tool change state in which the first tool change hole 3021 is exposed and the second tool change hole 3022 is covered, and a second tool change state in which the first tool change hole 3021 is covered and the second tool change hole 3022 is exposed.

[0067] It should be noted that one, two, or more tool holder turntables 2 can be installed on a single support shaft 1, and each tool holder turntable 2 is provided with a first tool change hole 3021 and a second tool change hole 3022. Each tool holder turntable 2 is also provided with a robotic arm 100 to further expand the load-bearing capacity of the tool 200. Since each tool holder turntable 2 is independent of the others and operates on the same principle, the following explanation focuses on the operating principle of one of the tool holder turntables 2.

[0068] Specifically, the cover assembly 3 includes a fixed cover assembly 301, a rotating cover 302, and a power module 303. The fixed cover assembly 301 is mounted and fixed above the tool holder turntable 2, and includes a front fixed cover 3011 located at the front end of the tool holder turntable 2, a rear fixed cover 3012 located at the rear end of the tool holder turntable 2, and a tool changing window 3013 located between the front fixed cover 3011 and the rear fixed cover 3012. The rotating cover 302 is rotatably mounted between the fixed cover assembly 301 and the tool holder turntable 2, and is provided with a first tool changing hole 3021 and a second tool changing hole 3022. The drive end of the power module 303 is connected to the rotating cover 302, driving the rotating cover 302 to rotate, so that the cover assembly 3 has either the first tool changing state or the second tool changing state.

[0069] In this embodiment, the first tool changing state refers to the first tool changing hole 3021 being opposite to the tool changing window 3013, and the second tool changing hole 3022 being covered by the rear fixing cover 3012; the second tool changing state refers to the second tool changing hole 3022 being opposite to the tool changing window 3013, and the first tool changing hole 3021 being covered by the front fixing cover 3011.

[0070] Optionally, a first photoelectric sensor 501 is provided at a position corresponding to one side of the tool holder turntable 2, and a second photoelectric sensor 502 is provided at a position corresponding to the other side of the tool holder turntable 2.

[0071] Taking the robotic arm 100 needing to pick up one of the tools 200 located on the left side of the tool holder turntable 2 as an example, the specific working process is as follows:

[0072] S101: The power module 303 drives the rotating cover 302 to rotate backward. During this process, the first tool changing hole 3021 on the rotating cover 302 will move backward to be opposite to the tool changing window 3013, while the second tool changing hole 3022 on the rotating cover 302 will move backward to be covered by the rear fixed cover 3012.

[0073] S102: The support rotation drives the tool holder turntable 2 to rotate. When the first photoelectric sensor 501 detects the preset target, it indicates that the tool 200 on the first chuck 401 that the robotic arm 100 needs to pick up is located directly below the first tool change hole 3021. At this time, the rotation of the support shaft 1 can be stopped.

[0074] S103: The robotic arm 100 moves downward, passes through the tool changing window 3013 and the first tool changing hole 3021 in sequence, and arrives near the tool holder turntable 2, and takes out the tool 200 to be used from the corresponding first chuck 401;

[0075] It should be noted that, since the rotating cover 302 is above the right side of the tool holder turntable 2, even if a foreign object falls from the robotic arm 100, it can only fall onto the rotating cover 302 and then slide down along the rotating cover 302, instead of falling directly onto the tool 200 of the second chuck 402 located on the right side of the tool holder turntable 2. This avoids the problem of foreign objects sticking to the tool 200 on the right side of the tool holder turntable 2 when the robotic arm 100 is picking up the tool 200 on the left side of the tool holder turntable 2.

[0076] S104: After the robotic arm 100 clamps the tool 200, it rises up and disengages from the cover assembly 3, allowing the workpiece to be machined.

[0077] Similarly, when the robotic arm 100 needs to pick up one of the tools 200 located on the right side of the tool holder turntable 2, the specific working process is as follows:

[0078] S201: The power module 303 drives the rotating cover 302 to rotate forward. During this process, the first tool changing hole 3021 on the rotating cover 302 will move forward until it is covered by the front fixed cover 3011, while the second tool changing hole 3022 on the rotating cover 302 will move forward until it is opposite to the tool changing window 3013.

[0079] S202: The support rotation drives the tool holder turntable 2 to rotate. When the second photoelectric sensor 502 detects the preset target, it indicates that the tool 200 on the second chuck 402 that the robotic arm 100 needs to pick up is located directly below the second tool change hole 3022. At this time, the rotation of the support shaft 1 can be stopped.

[0080] S203: The robotic arm 100 moves downward, passes through the tool changing window 3013 and the second tool changing hole 3022 in sequence, and arrives near the tool holder turntable 2, and takes out the tool 200 to be used from the corresponding second chuck 402;

[0081] It should be noted that, since the rotating cover 302 blocks the upper left side of the tool holder turntable 2, even if a foreign object falls from the robotic arm 100, it can only fall onto the rotating cover 302 and then slide down along the rotating cover 302, instead of falling directly onto the tool 200 of the second chuck 402 located on the left side of the tool holder turntable 2. This avoids the problem of foreign objects sticking to the tool 200 on the left side of the tool holder turntable 2 when the robotic arm 100 is picking up the tool 200 on the right side of the tool holder turntable 2.

[0082] S204: After the robotic arm 100 clamps the tool 200, it rises up and detaches from the cover assembly 3, allowing the workpiece to be machined.

[0083] In this embodiment, the power module 303 includes a linear drive mechanism 3031, a rotating component 3032, a transmission connector 3033, and a sliding bolt 3034. The rotating component 3032 includes a bearing seat 3032a rotatably connected to the supporting shaft 1 via a bearing, a first connecting plate 3032b fixed to the bearing seat 3032a and fastened to the rotating cover 302, and a second connecting plate 3032c with one end fixed to the bearing seat 3032a. One end of the transmission connector 3033 is provided with a strip-shaped groove 3033a, and the other end is connected to the drive end of the linear drive mechanism 3031. One end of the sliding bolt 3034 is hinged to the other end of the second connecting plate 3032c, and the other end of the sliding bolt 3034 slides along the strip-shaped groove 3033a.

[0084] Understandably, when the linear drive mechanism 3031 drives the transmission connector 3033 to move upward, the sliding bolt 3034 will slide along the strip groove 3033a away from the rotating member 3032 while moving upward with the transmission connector 3033. This causes the rotating member 3032 to rotate forward, thereby driving the rotating cover 302 to rotate forward, so that the second tool changing hole 3022 is opposite to the tool changing window 3013. Similarly, when the linear drive mechanism 3031 drives the transmission connector 3033 to move downward, the sliding bolt 3034 will slide along the strip groove 3033a towards the rotating member 3032 while moving upward with the transmission connector 3033. This causes the rotating member 3032 to rotate backward, thereby driving the rotating cover 302 to rotate backward, so that the first tool changing hole 3021 is opposite to the tool changing window 3013.

[0085] Of course, in some other embodiments, a rotary drive mechanism such as a motor or a rotary cylinder can be used to drive the rotating cover 302 to rotate back and forth. Compared with using a rotary drive mechanism, using a linear drive mechanism 3031 to drive the rotating cover 302 to rotate can reduce transmission components such as a gearbox, and reduce the volume and weight of the rotating cover type double-sided tool magazine.

[0086] Optionally, the linear drive mechanism 3031 can be a telescopic cylinder, a rodless cylinder, an electric cylinder, or a hydraulic cylinder, etc.

[0087] In this embodiment, a first air blowing pipe 601 is provided corresponding to one side of the tool holder turntable 2, and a second air blowing pipe 602 is provided corresponding to the other side of the tool holder turntable 2. Further, a recycling box 7 is provided below the tool holder turntable 2, the recycling box 7 having a collection groove opening towards the tool holder turntable 2 and an external discharge port 701 connecting the collection groove to the external space of the recycling box 7.

[0088] If the robotic arm 100 is changing a tool on the left side of the tool holder turntable 2, the first air pipe 601 will continuously blow the tool 200 on the left side. If there are foreign objects on the robotic arm 100 that fall down through the first tool changing hole 3021, they will also be blown away and fall into the collection tank, and finally be discharged through the external discharge port 701.

[0089] Similarly, if the robotic arm 100 changes the tool on the right side of the tool holder turntable 2, the second air pipe 602 continuously blows the tool 200 on the right side. If there are foreign objects on the robotic arm 100 that fall down through the second tool changing hole 3022, they will also be blown away and fall into the collection tank, and finally be discharged through the external discharge port 701.

[0090] The rotary cover type double-sided tool magazine and CNC machine tool provided in this embodiment have the following advantages:

[0091] ① By using the first tool change hole 3021 and the second tool change hole 3022 which are set in a staggered manner, one side of the tool holder turntable 2 is covered so as to ensure that when the robotic arm 100 takes the tool 200 on one side of the tool holder turntable 2, foreign objects will not fall onto the tool 200 on the other side of the tool holder turntable 2.

[0092] ② A linear drive mechanism 3031 is used to drive the rotating cover 302 to rotate back and forth, reducing the volume and size of the rotating cover type double-sided tool magazine;

[0093] ③ Install an air blowing pipe and a recovery box 7 to recover foreign objects that fall from the robotic arm 100, preventing them from scattering everywhere.

[0094] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0095] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
