Description

Technical Field

[0001] This utility model relates to the field of tool changing equipment technology, and in particular to a rapid tool changing device based on workpiece machining. Background Technology

[0002] Workpiece machining refers to the process in manufacturing where raw materials (i.e., workpieces) are altered in shape, size, surface quality, etc., through various mechanical or non-mechanical means to obtain parts or products that meet design requirements. It is a core process in many fields such as machinery manufacturing, mold making, aerospace, and the automotive industry. During workpiece machining, different workpieces require different cutting tools for different machining areas. Therefore, when machining a complete workpiece, it is necessary to constantly change tools. For this reason, we urgently need a rapid tool changer based on workpiece machining.

[0003] Currently, the tool storage area and the workpiece machining area are set up independently. When it is necessary to change the tool, the tool needs to be taken from the storage area to the machining area before the tool can be changed. However, this operation makes the tool changing process cumbersome, which will affect the tool changing efficiency and thus the workpiece machining efficiency. Utility Model Content

[0004] To address the shortcomings of existing production technologies, the applicant provides a rapid tool changer based on workpiece machining. By improving the structure of the tool changer, the tool storage mechanism and the tool changing mechanism are placed on one side of the workpiece machining area, thereby simplifying the tool changing process and improving tool changing efficiency.

[0005] The technical solution adopted in this utility model is as follows: A rapid tool changer based on workpiece machining is provided. The tool changer is located on one side of the workpiece machining area. The tool changer includes a tool storage section and a tool changing mechanism. The tool storage section stores multiple tools. The tool changing mechanism is located between the tool storage section and a first driving member. The tool changing mechanism is used to remove the tools from the tool storage section, remove the tools from the first driving member, install the tools removed from the tool storage section onto the first driving member, and place the tools removed from the first driving member back onto the tool storage section, thereby realizing the tool replacement operation on the first driving member.

[0006] Therefore, by placing the tool storage unit and tool changing mechanism on one side of the workpiece machining area, compared to the existing method of setting the tool storage area and workpiece machining area separately, this method has a simpler structure and is easier to operate. During the tool changing process, there is no need to carry the tool over a long distance, which shortens the tool transport distance, simplifies the tool changing process, improves the tool changing efficiency, and improves the workpiece machining efficiency. In addition, during the tool changing process, both the tool changing mechanism and the first driving component can move, so that the tool changing can be completed at a position away from the workpiece, ensuring that the workpiece will not interfere with the tool changing on the first driving component.

[0007] As a further improvement to the above technical solution: the tool storage section has multiple storage slots; wherein: when storing the tool, the tool is slidably inserted into the storage slot and slidably connected to the tool storage section. Thus, multiple storage slots can store multiple tools; by providing storage slots in the tool storage section, when retrieving a tool, it is only necessary to pull the tool away from the tool storage section under the action of external force; when placing a tool, it is only necessary to insert the tool closer to the tool storage section under the action of external force, thus facilitating quick retrieval and placement of tools and further improving tool replacement efficiency.

[0008] As a further improvement to the above technical solution: the tool changing mechanism includes a second driving member and a tool changing part, the tool changing part is installed on the driving end of the second driving member, and the second driving member is used to drive the tool changing part to move so as to realize the tool changing operation on the first driving member.

[0009] As a further improvement to the above technical solution: the tool changing unit includes: a first changing blade and a second changing blade, the first changing blade and the second changing blade are connected, and both the first changing blade and the second changing blade are connected to the driving end of the second driving member; wherein: the first changing blade is used to remove the tool from the tool storage unit and then install the tool removed from the tool storage unit onto the first driving member; and / or, the second changing blade is used to remove the tool from the first driving member and then place the tool removed from the first driving member back onto the tool storage unit.

[0010] As a further improvement to the above technical solution, a first tool changing groove is formed on the side of the first tool changing blade away from the second tool changing blade. Therefore, by creating the first tool changing groove on the side of the first tool changing blade away from the second tool changing blade, when retrieving the tool, the first tool changing blade only needs to be inserted into the tool with the side closest to the tool under external force to retrieve it; when placing the tool, the first tool changing blade only needs to be pulled out of the tool with the side away from the tool under external force to place it, thus facilitating quick retrieval and placement of tools and further improving tool changing efficiency.

[0011] As a further improvement to the above technical solution, a second tool changing groove is provided on the side of the second tool changing blade away from the first tool changing blade. Therefore, by creating a second tool changing groove on the side of the second tool changing blade away from the first tool changing blade, when retrieving the tool, the tool can be retrieved simply by inserting the second tool changing blade onto the tool with the side closest to the tool under external force; when placing the tool, the tool can be placed simply by pulling the second tool changing blade away from the tool with external force. This facilitates quick retrieval and placement of tools, further improving tool changing efficiency.

[0012] As a further improvement to the above technical solution: the first and second changing blades are perpendicular to each other, and the driving end of the second driving member is installed at the connection between the first and second changing blades. Thus, the perpendicular design of the first and second changing blades ensures that their tool changing operations do not interfere with each other, facilitating rapid tool replacement and further improving tool replacement efficiency. Furthermore, the design of the second driving member's driving end being installed at the connection between the first and second changing blades ensures that a certain distance is maintained between the first and second driving members, thereby ensuring that the movements of the first and second driving members do not interfere with each other, facilitating rapid tool replacement and further improving tool replacement efficiency.

[0013] As a further improvement to the above technical solution: multiple first driving components are provided, and the tool storage unit and the tool changing mechanism are located in the central area of ​​the multiple first driving components. Therefore, the multiple first driving components can share the tool storage unit and the tool changing mechanism, reducing the number of components in the entire quick tool changer and thus lowering the overall production cost of the quick tool changer.

[0014] As a further improvement to the above technical solution: the tool storage unit, the tool changing mechanism, and the first driving component are all located on the same side of the worktable. Therefore, by having the tool storage unit, the tool changing mechanism, and the first driving component all located on the same side of the worktable, tool changing operations do not require crossing the worktable, thereby improving tool changing efficiency and workpiece machining efficiency.

[0015] As a further improvement to the above technical solution: the worktable is used to support the workpiece. Thus, the cutting tool is driven by the first driving component to move, thereby realizing the machining operation of the workpiece.

[0016] The beneficial effects of this utility model are as follows: This invention places the tool storage unit and tool changing mechanism on one side of the workpiece processing area. Compared with the existing method of setting the tool storage area and workpiece processing area independently, this method has a simple structure and is easy to operate. During the tool changing process, there is no need to carry the tool over a long distance, which shortens the tool transport distance, simplifies the tool changing process, improves the tool changing efficiency, and improves the workpiece processing efficiency. In addition, during the tool changing process, both the tool changing mechanism and the first driving component can move. In this way, the tool changing can be completed at a position away from the workpiece, ensuring that the workpiece will not interfere with the tool changing on the first driving component.

[0017] This utility model also has the following advantages: 1. This utility model has multiple storage slots that can store multiple cutting tools. By opening storage slots in the cutting tool storage section, when taking out a cutting tool, it is only necessary to pull the cutting tool away from the cutting tool storage section under the action of external force. When placing a cutting tool, it is only necessary to insert the cutting tool into the side closer to the cutting tool storage section under the action of external force. This facilitates quick taking out and placing of cutting tools and further improves the efficiency of cutting tool replacement.

[0018] 2. This utility model employs a design where the first and second changing blades are perpendicular to each other to ensure that their changing operations do not interfere with each other, facilitating rapid tool replacement and further improving tool replacement efficiency. Furthermore, the design where the driving end of the second driving component is installed at the connection point between the first and second changing blades ensures that a certain distance is maintained between them, thus guaranteeing that the movements of the first and second driving components do not interfere with each other, further facilitating rapid tool replacement and improving tool replacement efficiency.

[0019] 3. The multiple first driving components of this utility model can work together in the tool storage section and the tool changing mechanism, which can reduce the number of the entire quick tool changing device and thus reduce the production cost of the entire quick tool changing device.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figures 1 to 7 The diagram shows the preferred embodiment of this utility model. This embodiment is a rapid tool changer based on workpiece machining. The tool changer is located on one side of the workpiece machining area. The tool changer includes a tool storage section 1 and a tool changing mechanism 3. The tool storage section 1 stores multiple tools 2. The tool changing mechanism 3 is located between the tool storage section 1 and the first driving member 4. The tool changing mechanism 3 is used to remove the tools 2 from the tool storage section 1, remove the tools 2 from the first driving member 4, install the tools 2 removed from the tool storage section 1 onto the first driving member 4, and place the tools 2 removed from the first driving member 4 back onto the tool storage section 1, so as to realize the tool 2 replacement operation on the first driving member 4. Therefore, by placing the tool storage unit 1 and the tool changing mechanism 3 on one side of the workpiece processing area, compared with the existing method of setting the tool storage area and the workpiece processing area independently, this method has a simple structure and is easy to operate. During the tool changing process, there is no need to carry the tool 2 over a long distance, which shortens the tool 2 transport distance, simplifies the tool 2 changing process, improves the tool 2 changing efficiency, and improves the workpiece processing efficiency. In addition, during the tool 2 changing process, both the tool changing mechanism 3 and the first driving member 4 can move. In this way, the tool 2 can be changed at a position away from the workpiece, ensuring that the workpiece will not interfere with the tool 2 changing on the first driving member 4.

[0024] In other words, this application places the tool storage unit 1 and the tool changing mechanism 3 on one side of the workpiece processing area. When changing the tool 2, the path for transporting the tool 2 between the tool storage unit 1 and the first driving member 4 is greatly shortened. Thus, by shortening the tool changing path, the tool changing process of the tool 2 is simplified, thereby improving the tool changing efficiency and thus improving the workpiece processing efficiency.

[0025] Specifically, the installation of the tool 2 on the first drive member 4 means that the tool 2 is installed on the drive end of the first drive member 4. The drive end of the first drive member 4 is provided with a clamp (not shown in the figure, for example: a gripper cylinder). The tool 2 is installed and removed by clamping and releasing the clamp (that is, when the clamp is clamped, the tool 2 is installed on the first drive member 4, and when the clamp is released, the tool 2 is removed from the first drive member 4).

[0026] For example, the first drive unit 4 uses a six-axis robot.

[0027] In this embodiment, the tool storage unit 1 has multiple storage slots 101. When storing a tool 2, the tool 2 is slidably inserted into the storage slot 101 and slidably connected to the tool storage unit 1. Thus, the multiple storage slots 101 can store multiple tools 2. By providing storage slots 101 in the tool storage unit 1, when retrieving a tool 2, it is only necessary to pull the tool 2 away from the tool storage unit 1 under the action of external force. When placing a tool 2, it is only necessary to insert the tool 2 into the side closer to the tool storage unit 1 under the action of external force. This facilitates the quick retrieval and placement of the tool 2, further improving the tool replacement efficiency.

[0028] It should be noted that: 1. The taking of tool 2 from tool storage unit 1 refers to the action of removing tool 2 from tool storage unit 1, detaching it from tool storage unit 1, and placing it on tool changing mechanism 3. 2. Placing the tool 2 on the tool storage unit 1 refers to the action of removing the tool 2 from the tool changing mechanism 3, separating it from the tool changing mechanism 3, and placing it on the tool storage unit 1.

[0029] In this embodiment, the tool changing mechanism 3 includes a second driving member 301 and a tool changing part 302. The tool changing part 302 is installed on the driving end of the second driving member 301. The second driving member 301 drives the tool changing part 302 to move, thereby realizing the tool changing operation on the first driving member 4. The tool changing part 302 includes a first changing blade 303 and a second changing blade 304. The first changing blade 303 and the second changing blade 304 are connected and perpendicular to each other. The driving end of the second driving member 301 is installed at the connection between the first changing blade 303 and the second changing blade 304. Both the first blade 303 and the second blade changer 304 are connected to the drive end of the second drive member 301. The first blade changer 303 has a first blade changer groove 305 on the side away from the second blade changer 304, and the second blade changer 304 has a second blade changer groove 306 on the side away from the first blade changer 303. The first blade changer 303 is used to remove the blade 2 from the tool storage unit 1 and then install the blade 2 removed from the tool storage unit 1 onto the first drive member 4. And / or, the second blade changer 304 is used to remove the blade 2 from the first drive member 4 and then place the blade 2 removed from the first drive member 4 back onto the tool storage unit 1. Therefore, by starting the first tool changing groove 305 on the side of the first tool changing blade 303 away from the second tool changing blade 304, when picking up the tool 2, it is only necessary to insert the first tool changing blade 303 onto the tool 2 with the side closer to the tool 2 under the action of external force to achieve tool 2 retrieval. When placing the tool 2, it is only necessary to pull the first tool changing blade 303 off the tool 2 with the side away from the tool 2 under the action of external force to achieve tool 2 placement, so as to facilitate quick retrieval and placement of the tool 2 and further improve the tool 2 replacement efficiency; by starting the second tool changing groove 306 on the side of the second tool changing blade 304 away from the second tool changing blade 304, when picking up the tool 2, it is only necessary to insert the second tool changing blade 304 onto the tool 2 with the side closer to the tool 2 under the action of external force to achieve tool 2 retrieval. When placing the tool 2, it is only necessary to pull the first tool changing blade 303 off the tool 2 with the side closer to the tool 2 under the action of external force to achieve tool 2 retrieval. The second blade 304 is pulled away from the tool 2 by the action of the blade, which allows the tool 2 to be placed, so as to facilitate the quick picking and placing of the tool 2 and further improve the tool 2 replacement efficiency. The design of the first blade 303 and the second blade 304 being perpendicular to each other ensures that the tool changing operations of the first blade 303 and the second blade 304 do not interfere with each other, so as to facilitate the quick replacement of the tool 2 and further improve the tool 2 replacement efficiency. The design of the second drive member 301 being installed at the connection between the first blade 303 and the second blade 304 ensures that the first drive member 4 and the second drive member 301 maintain a certain distance. In this way, it can be ensured that the movement of the first drive member 4 and the movement of the second drive member 301 do not interfere with each other, so as to facilitate the quick replacement of the tool 2 and further improve the tool 2 replacement efficiency.

[0030] It should be noted that the tool changing unit 302 of this application adopts a single first tool changing blade 303, a single second tool changing blade 304, or a combination of the first tool changing blade 303 and the second tool changing blade 304. If a single first tool changing blade 303 or a single second tool changing blade 304 is used, the tool changing action is as follows: the first tool changing blade 303 or the second tool changing blade 304 first removes the original tool 2 (i.e., the old tool 2) from the first drive member 4 and places it on the tool storage unit 1, and then removes the tool 2 to be replaced (i.e., the new tool 2) from the tool storage unit 1. If the first blade changer 303 and the second blade changer 304 are combined and placed on the first drive member 4, the blade changing action is as follows: the first blade changer 303 removes the blade 2 to be replaced (i.e., the new blade 2) from the blade storage section 1. The first blade changer 303 and the second blade changer 304 move to the position of the first drive member 4. The second blade changer 304 first removes the original blade 2 (i.e., the old blade 2) from the first drive member 4. Then the first blade changer 303 places the blade 2 to be replaced (i.e., the new blade 2) onto the first drive member 4.

[0031] It should be noted that: 1. The action of the first blade changer 303 or the second blade changer 304 taking the blade 2 refers to the action of taking the blade 2 off the blade storage unit 1 or the first driving member 4 and separating it from the blade storage unit 1 or the first driving member 4, and placing it on the first blade changer 303 or the second blade changer 304. 2. The placement of the tool 2 by the first blade changer 303 or the second blade changer 304 refers to the action of removing the tool 2 from the first blade changer 303 or the second blade changer 304 and placing it on the tool storage unit 1 or the first drive unit 4.

[0032] For example, the second drive unit 301 uses a six-axis robot.

[0033] In this embodiment, multiple first driving members 4 are provided, and the tool storage unit 1 and the tool changing mechanism 3 are located in the central area of ​​the multiple first driving members 4. Therefore, the multiple first driving members 4 can share the tool storage unit 1 and the tool changing mechanism 3, reducing the number of components in the entire quick tool changer and thus lowering the overall production cost of the quick tool changer.

[0034] It should be noted that: such as Figure 5 , 6As shown, the following example illustrates a tool storage unit 1, two tool changing mechanisms 3, and four first driving components 4: the two tool changing mechanisms 3 are denoted as A tool changing mechanism 3 and B tool changing mechanism 3, and the four first driving components 4 are denoted as A first driving component 4, B first driving component 4, C first driving component 4, and D first driving component 4. The four first driving components 4 are arranged in a circle, with the tool storage unit 1 located at the center of the four first driving components 4. The two tool changing mechanisms 3 are located on both sides of the tool storage unit 1. A tool changing mechanism 3 is used for tool changing operations of A first driving component 4 and B first driving component 4, and B tool changing mechanism 3 is used for tool changing operations of C first driving component 4 and D first driving component 4.

[0035] In this embodiment, the tool storage unit 1, the tool changing mechanism 3, and the first driving member 4 are all located on the same side of the worktable 5, which is used to support the workpiece. Therefore, by having the tool storage unit 1, the tool changing mechanism 3, and the first driving member 4 all located on the same side of the worktable 5, the tool 2 can be changed without crossing the worktable 5, thus improving the tool 2 changing efficiency and the workpiece machining efficiency. The first driving member 4 drives the tool 2 to move, thereby realizing the workpiece machining operation.

[0036] The replacement process of the cutting tool 2 of this utility model (taking the combination of the first changing blade 303 and the second changing blade 304 as an example) is as follows: First, the first changing blade 303 removes the cutting tool 2 to be replaced (i.e., the new cutting tool 2) from the cutting tool storage unit 1; then, the second driving member 301 drives the cutting tool changing unit 302 from the position of the cutting tool storage unit 1 to the position of the first driving member 4 (if the first driving member 4 remains in its original position, it will interfere with the cutting tool replacement operation, so the first driving member 4 and the second driving member 301 are started simultaneously to ensure that the cutting tool replacement position is not interfered with); then, the second changing blade 304 removes the original cutting tool 2 (i.e., the old cutting tool 2) from the first driving member 4; finally, the cutting tool 2 to be replaced (i.e., the new cutting tool 2) on the first changing blade 303 is placed on the first driving member 4, and then the second driving member 301 drives the cutting tool changing unit 302 from the position of the first driving member 4 to the position of the cutting tool storage unit 1, so as to place the original cutting tool 2 (i.e., the old cutting tool 2) on the first driving member 4 onto the cutting tool storage unit 1.

[0037] In summary, this utility model places the tool storage unit 1 and the tool changing mechanism 3 on one side of the workpiece processing area. Compared with the existing method where the tool storage area and the workpiece processing area are set up independently, this method has a simple structure and is easy to operate. During the tool changing process, there is no need to carry the tool 2 from a long distance, which shortens the transport distance of the tool 2, simplifies the tool changing process, improves the tool changing efficiency, and improves the workpiece processing efficiency. In addition, during the tool changing process, both the tool changing mechanism 3 and the first driving member 4 can move. In this way, the tool changing can be completed at a position away from the workpiece, ensuring that the workpiece will not interfere with the tool changing on the first driving member 4.
