Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to a tool changing device and a machining system having the same. Background Technology

[0002] Currently, vertical machining centers are widely used in various precision machining processes. To improve machining efficiency and accuracy, vertical machining centers are usually equipped with a tool magazine system for storing and changing different tools. As an important part of the tool magazine system, the tool changer arm is mainly responsible for taking the tool out of the tool magazine and installing it onto the machine tool spindle to complete the tool change.

[0003] In the existing technology, when the tool changer arm is used to change to different types of tools, in order to ensure that the tool changer arm can stably clamp different types of tools, the operator usually needs to manually adjust the position of some structural parts of the tool changer arm to adapt to tools of different specifications and sizes, thereby ensuring the reliability of the tool changer arm.

[0004] However, manual adjustment is easily affected by the working environment, making adjustments inconvenient. Furthermore, manual adjustment is time-consuming and labor-intensive, reducing work efficiency and consequently decreasing the tool-changing efficiency of the tool-changing arm.

[0006] To achieve the above objectives, according to one aspect of the present invention, a tool changing device is provided, comprising: a main body structure having a receiving recess; an abutting structure movably disposed on the main body structure, the abutting structure having an abutting position for abutting a part to be replaced within the receiving recess and a separating position for separating from the part to be replaced; a driving assembly drivingly connected to the abutting structure to drive the abutting structure to move toward or away from the receiving recess; and a locking structure disposed on the main body structure to limit and stop the part to be replaced.

[0007] Furthermore, the locking structure has a locking protrusion that extends into the recess of the replacement part during the process of the receiving recess accommodating the replacement part.

[0008] Furthermore, the driving component includes: a pushing structure disposed on the main structure; and a reset structure disposed on the main structure and connected to the abutting structure; wherein the pushing structure has a pushing position and a yielding position. When the pushing structure is in the pushing position, the pushing structure contacts the abutting structure to drive the abutting structure to move toward the part to be replaced; when the pushing structure is in the yielding position, the pushing structure yields to the abutting structure so that the reset structure drives the abutting structure away from the part to be replaced.

[0009] Furthermore, the main structure has an installation cavity, and at least part of the abutment structure is located within the installation cavity; wherein, the reset structure is sleeved on the abutment structure and located within the installation cavity, one end of the reset structure is connected to the cavity wall of the installation cavity, and the other end of the reset structure is connected to the end of the abutment structure near the receiving recess.

[0010] Furthermore, the main structure also has a through hole and a receiving cavity, the through hole and the receiving cavity are connected, at least part of the pushing structure extends out of the receiving cavity through the through hole, and the driving component also includes: a driving structure, which is drivenly connected to the pushing structure to drive the pushing structure to move along the extension direction of the through hole; wherein, the pushing structure has a connecting inclined surface, the connecting inclined surface cooperates with the abutting structure to push the abutting structure to move through the connecting inclined surface during the movement of the pushing structure.

[0011] Furthermore, the tool changing device also includes a limiting structure, which is located at one end of the main structure near the receiving recess, and the abutting structure passes through the limiting structure to abut against the part to be replaced.

[0013] Furthermore, the tool changing device also includes: a detection module, which is installed on the main structure to detect the position of the contact structure; and a control module, which is connected to both the detection module and the drive component to control the operation or shutdown of the drive component based on the detection value of the detection module.

[0014] Furthermore, the tool changing device also includes: an alarm module for issuing an alarm signal, the alarm signal including at least one of an audible signal and a visual signal; wherein, the control module is connected to the alarm module to control the operation or shutdown of the alarm module based on the detected value.

[0016] The present invention provides a tool changing device with a receiving recess in its main structure. A contact structure is movably mounted on the main structure, having a contact position where the tool to be replaced is contacted within the receiving recess and a separation position where it is separated from the tool. A drive assembly is connected to the contact structure to drive it to move toward or away from the receiving recess. A locking structure is mounted on the main structure to limit and stop the tool to be replaced.

[0034] To address the problem of low tool changing efficiency in existing tool changing arms, this application provides a tool changing device and a machining system incorporating it.

[0035] like Figures 1 to 6 As shown, the tool changing device includes a main structure 10, an abutment structure 30, a drive assembly 40, and a locking structure 50. The main structure 10 has a receiving recess 11. The abutment structure 30 is movably disposed on the main structure 10, and has an abutment position where the replacement part 1 is abutted in the receiving recess 11 and a separation position where it is separated from the replacement part 1. The drive assembly 40 is drivenly connected to the abutment structure 30 to drive the abutment structure 30 to move toward or away from the receiving recess 11. The locking structure 50 is disposed on the main structure 10 to limit and stop the replacement part 1.

[0036] Applying the technical solution of this embodiment, the main structure 10 of the tool changing device has a receiving recess 11. An abutment structure 30 is movably disposed on the main structure 10, and the abutment structure 30 has an abutment position where the replacement part 1 abuts against the receiving recess 11 and a separation position where it separates from the replacement part 1. A drive assembly 40 is drivenly connected to the abutment structure 30 to drive the abutment structure 30 to move towards or away from the receiving recess 11. A locking structure 50 is disposed on the main structure 10 to limit and stop the replacement part 1. Thus, when the tool changing device needs to replace the tool on the machine tool spindle, the drive assembly 40 drives the abutment structure 30 to move, causing the abutment structure 30 to switch between the abutment position and the separation position. This also allows the receiving recess 11 to accommodate tools of different specifications and sizes, ensuring the versatility of the tool changing device, avoiding manual operation by the operator, reducing the difficulty of operation, improving the operator's work efficiency, and thus improving the tool changing efficiency of the tool changing arm, thereby solving the problem of low tool changing efficiency in the prior art. Meanwhile, the locking structure 50 is designed so that after the receiving recess 11 receives the tool and the abutting structure 30 abuts the tool, the locking structure 50 can limit and stop the tool, further fixing the tool to ensure the clamping stability of the tool changing device and the reliability and stability of the tool changing device.

[0037] In this embodiment, the component to be replaced, 1, is a cutting tool.

[0038] In this embodiment, there are two receiving recesses 11, which are arranged on opposite sides of the main structure 10.

[0039] like Figure 4 As shown, the locking structure 50 has a locking protrusion 51. During the process of the receiving recess 11 accommodating the replacement part 1, the locking protrusion 51 extends into the recess 101 of the replacement part 1. In this way, the locking structure 50, through the locking protrusion 51 extending into the recess 101 of the tool, achieves a snap-fit ​​engagement between the locking structure 50 and the tool, ensuring the locking reliability of the locking structure 50 and further ensuring the clamping reliability of the tool changing device on the tool.

[0040] like Figure 1 and Figure 3As shown, the drive assembly 40 includes a pushing structure 41 and a reset structure. The pushing structure 41 is disposed on the main body structure 10. The reset structure is disposed on the main body structure 10 and connected to the abutment structure 30. The pushing structure 41 has a pushing position and a yielding position. When the pushing structure 41 is in the pushing position, it contacts the abutment structure 30, driving the abutment structure 30 towards the replacement part 1. When the pushing structure 41 is in the yielding position, it yields to the abutment structure 30, allowing the reset structure to move the abutment structure 30 away from the replacement part 1. Thus, the drive assembly 40 drives the abutment structure 30 towards the tool via the pushing structure 41 and drives it away from the tool via the reset structure, achieving reliable driving of the abutment structure 30 and ensuring its operational reliability. Simultaneously, the reset structure configuration reduces the use of drive energy, lowers the operating and maintenance costs of the drive assembly 40, and improves its economic efficiency.

[0041] In this embodiment, the reset structure is a spring.

[0042] Specifically, the main structure 10 has a mounting cavity, and at least part of the abutment structure 30 is located within the mounting cavity. The reset structure is sleeved on the abutment structure 30 and located within the mounting cavity. One end of the reset structure is connected to the cavity wall, and the other end is connected to the end of the abutment structure 30 near the receiving recess 11. Thus, both the reset structure and the abutment structure 30 are located within the mounting cavity, saving installation space and further optimizing the structural design of the tool changing device. Simultaneously, when the pushing structure 41 pushes the abutment structure 30 towards the tool, one end of the reset structure is positioned on the mounting cavity, and the other end moves with the abutment structure 30, causing the reset structure to be stretched. When the pushing structure 41 avoids the abutment structure 30, the reset structure resets and moves the abutment structure 30 away from the tool, thereby realizing the reciprocating motion of the abutment structure 30.

[0043] like Figures 1 to 3As shown, the main structure 10 also has a through hole 12 and a receiving cavity. The through hole 12 communicates with the receiving cavity. At least a portion of the pushing structure 41 extends out of the receiving cavity through the through hole 12. The drive assembly 40 also includes a drive structure, which is drivenly connected to the pushing structure 41 to drive the pushing structure 41 to move along the extension direction of the through hole 12. The pushing structure 41 has a connecting inclined surface 411, which cooperates with the abutting structure 30 to push the abutting structure 30 during the movement of the pushing structure 41. In this way, the main structure 10 accommodates the pushing structure 41 through the receiving cavity, reducing the volume occupied by the main structure 10 and achieving a miniaturized design of the tool changing device. Simultaneously, the cooperation between the connecting inclined surface 411 and the abutting structure 30 transforms the movement of the pushing structure 41 along the extension direction of the through hole 12 into the movement of the abutting structure 30 towards the tool, ensuring the reliability of the transmission of the driving force of the drive structure. At the same time, the above settings reduce the energy demand of the drive structure, save on the cost of the drive structure, and improve the economic efficiency of the drive structure.

[0044] In this embodiment, the driving structure includes a driving member and an elastic member. The elastic member is disposed in the receiving cavity. The driving member drives the pushing structure 41 to move toward the receiving cavity along the extension direction of the through hole 12. The elastic member is compressed. After the tool is inserted into the receiving cavity, the driving member stops driving. The rebound force of the elastic member drives the pushing structure 41 to move away from the receiving cavity along the extension direction of the through hole 12, so that part of the pushing structure 41 extends out of the through hole 12 and pushes the abutting structure 30 toward the tool.

[0045] like Figures 1 to 4 As shown, the tool changing device also includes a limiting structure 60, which is located at one end of the main structure 10 near the receiving recess 11. The abutting structure 30 passes through the limiting structure 60 and abuts against the part 1 to be replaced. Thus, during the movement of the abutting structure 30, the limiting structure 60 can limit the movement of the abutting structure 30, ensuring that the abutting structure 30 always moves in a predetermined direction. This prevents the abutting structure 30 from shifting or dislodging due to external forces or the action of the reset structure, further ensuring the reliability of the movement of the abutting structure 30 and improving the tool changing reliability and efficiency of the tool changing device.

[0046] like Figures 1 to 4As shown, the abutment structure 30 includes a main body 31, a connecting part 32, and an abutment part 33. The main body 31 is disposed within the mounting cavity for housing the reset structure. The connecting part 32 is fitted onto the end of the main body 31 near the receiving recess 11 for connection with the reset structure. The abutment part 33 is disposed on the end of the main body 31 near the receiving recess 11 for abutting against the replacement part 1. Thus, the arrangement of the main body 31 provides support and guidance for the reset structure, ensuring the operational reliability and stability of the reset structure. Simultaneously, the arrangement of the connecting part 32 achieves the connection between the reset structure and the abutment structure 30, ensuring the reliability of the connection and thus the reliability of the movement of the abutment structure 30. Furthermore, the arrangement of the abutment part 33 achieves the connection between the abutment structure 30 and the cutting tool, ensuring the reliability of the clamping of the cutting tool by the abutment structure 30 and the receiving recess 11.

[0047] Specifically, the tool changing device also includes a detection module and a control module. The detection module is mounted on the main structure 10 to detect the position of the abutment structure 30. The control module is connected to both the detection module and the drive assembly 40 to control the operation or shutdown of the drive assembly 40 based on the detection value from the detection module. In this way, the detection module can detect in real time whether the abutment structure 30 is abutting the tool, and the control module controls the drive assembly 40 to move the abutment structure 30 based on the detection value, ensuring that the abutment structure 30 abuts the tool. This guarantees the reliability of the clamping of the tool by the abutment structure 30 and the receiving recess 11, improving the tool changing reliability and efficiency of the tool changing device.

[0048] Specifically, the tool changing device also includes an alarm module. The alarm module is used to issue alarm signals, which include at least one of audible and visual signals. The control module is connected to the alarm module to control its operation or shutdown based on detected values. In this way, the alarm module can remind operators to check whether the abutment structure 30 and the receiving recess 11 are stably clamping the tool, enabling timely inspection and maintenance of the tool changing device and further improving its tool changing efficiency.

[0049] This application also provides a machining system, which includes the tool changing device described above.

[0050] In this embodiment, the machining system includes a main equipment, a tool magazine equipment, and a machine tool equipment. The main equipment is used to install the tool changing device, the tool magazine equipment provides a variety of cutting tools, and the machine tool equipment is used for machining and production. The main equipment includes a drive device, which is drivenly connected to the main structure 10 of the tool changing device to drive the tool changing device to move.

[0051] In this embodiment, the machining system also includes an identification module to identify the type and size of the tool to be replaced, and to identify the specific location of the tool. The control module is connected to both the identification module and the drive device. The control module controls the drive device to move the tool changing device up, down, and translating to the tool position based on the identification data from the identification module. Then, the drive structure of the drive assembly 40 drives the pushing structure 41 to move. The connecting inclined surface 411 of the pushing structure 41 engages with the abutting structure 30, causing the abutting structure 30 to move towards the tool. The locking structure 50 engages with the tool. During this process, the reset structure is stretched. When the detection module detects that the abutting structure 30 is in contact with the tool, the control module controls the drive structure to stop driving and controls the drive device to move the tool changing device up, down, and rotate to remove and rotate the tool. This removes the old tool from the machine tool and installs a new tool in the tool magazine, thus achieving tool replacement.

[0052] In this embodiment, the identification module is either a sensor or a camera.

[0053] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0054] The main structure of the tool changer has a receiving recess. A contact structure is movably mounted on the main structure, having a contact position where the tool to be replaced is abutted against the receiving recess and a separation position where it is separated from the tool. A drive assembly is driven by the contact structure to move it toward or away from the receiving recess. A locking structure is mounted on the main structure to limit and stop the tool to be replaced. Thus, when the tool changer needs to change the tool on the machine tool spindle, the drive assembly drives the contact structure to switch between the contact and separation positions. This allows the receiving recess to accommodate tools of different specifications and sizes, ensuring the versatility of the tool changer, eliminating manual operation, reducing operator difficulty, and improving work efficiency. This, in turn, increases the tool changing efficiency of the tool changing arm, solving the problem of low tool changing efficiency in existing tool changing arms. Meanwhile, the locking structure is designed so that after the receiving recess accommodates the tool and the abutting structure abuts the tool, the locking structure can limit and stop the tool, further fixing the tool to ensure the clamping stability of the tool changing device and the reliability and stability of the tool changing device.
