Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a debugging fixture and machine tool mechanism for an automatic tool changer. Background Technology

[0002] With the development of modern manufacturing, CNC machine tools are being used more and more widely. Among them, machining centers have become the fastest-growing and most in-demand CNC machine tools due to their high efficiency and high precision in machining complex parts. The most significant feature that distinguishes machining centers from ordinary CNC machine tools is the presence of an automatic tool changer (ATC, commonly known as a tool magazine). In medium and large-sized machining centers, where the internal space is large, the automatic tool changer is usually a cam box + chain tool magazine, and the debugging process for this type of tool magazine is relatively mature. However, compact machining centers, due to their limited internal space, typically use self-pickup chain tool magazines if a larger capacity tool magazine is required.

[0003] The traditional method for adjusting a robotic arm-type tool magazine requires installing adjustment fixture A onto the tool holder and matching adjustment fixture B onto the robotic arm. Then, the tool magazine and robotic arm are rotated, and adjustment fixture C is used to check the concentricity of fixture A and fixture B, ultimately ensuring the concentricity of the tool holder and robotic arm.

[0004] However, the inherent structure and compact layout of the self-pickup chain tool magazine dictate that the tool magazine adjustment operation is quite confined. Using traditional adjustment methods would be extremely cumbersome. First, the tool holder must be raised (tooling A cannot be directly installed onto the tool holder due to interference, requiring the removal of some parts from the tool magazine). Then, tooling C is used to check the concentricity of tooling A and tooling B. Next, the tool holder must be lowered to rotate the tool magazine. After rotating a certain distance, it needs to be raised again so that tooling C can be used to check the concentricity of tooling A and tooling B. This process needs to be repeated multiple times to find the appropriate position, which is very time-consuming and labor-intensive. Utility Model Content

[0005] This utility model provides a debugging fixture and machine tool mechanism for an automatic tool changer, which solves the defects of the existing self-pickup chain tool magazine, which is subject to additional cumbersome operation, time and labor consumption and inaccurate debugging results due to space limitations. It simplifies the debugging operation process and improves the debugging accuracy and efficiency.

[0006] This utility model provides a debugging fixture for an automatic tool changer, including: A tool position adjustment fixture is installed on the tool holder mounting position of the tool magazine to be adjusted. The tool position adjustment fixture has a center hole, which is coaxially arranged with the center hole of the tool holder. A test ring fixture, which has the same shape and size as the tool holder, is mounted on the jaws of a robotic arm used for tool changing on a machine tool, and the test ring fixture is coaxially arranged with the clamping jaws of the robotic arm. A central shaft fixture is installed on the central hole, with both ends of the central shaft fixture extending along a first direction, and one end of the central shaft fixture being coaxially and movably connected to the debugging ring fixture.

[0007] According to the present invention, an automatic tool changer debugging fixture is provided, wherein the central shaft fixture and the debugging ring fixture are coaxially connected.

[0008] According to the present invention, an automatic tool changer debugging fixture has a first end face and a second end face arranged opposite to each other, the first end face and the second end face being flush with the end face corresponding to the clamping jaw of the robotic arm.

[0009] According to the present invention, an automatic tool changer debugging fixture is provided, the tool position debugging fixture includes a fixture body and a lifting rod, the fixture body is connected to the tool sleeve mounting position through the lifting rod, and the center hole is formed on the fixture body.

[0010] According to the present invention, an automatic tool changer debugging fixture is provided, wherein the fixture body has a lifting hole, the lifting hole is opened along a first direction, and the lifting rod passes through the lifting hole.

[0011] According to the present invention, an automatic tool changer debugging fixture is provided, the fixture body includes a fixed section, a transition section and a mating section, the fixed section is provided with the lifting hole, the fixed section is connected to the lifting rod through the lifting hole, the transition section is arc-shaped and connects the fixed section and the mating section, and the mating section is provided with the center hole.

[0012] According to the present invention, an automatic tool changer debugging fixture is provided, wherein the fixture body is arranged in a stepped manner, and the fixture body is arranged in an upward trend from the mating section to the fixing section.

[0013] According to the debugging fixture of the automatic tool changer provided by this utility model, there are two lifting rods, and the fixed section is provided with two lifting holes arranged side by side along the second direction, and the two lifting rods are respectively inserted into the two lifting rods.

[0014] This utility model also provides a machine tool mechanism, which includes a tool magazine, a robot arm, an ejection mechanism, and a debugging fixture for the automatic tool changer as described above. The robot arm is mounted on the output shaft of the ejection mechanism, the tool position debugging fixture is mounted on the tool sleeve mounting position of the tool magazine to be debugged, the central shaft fixture is connected to the tool position debugging fixture, and the debugging ring fixture is mounted in the jaw of the robot arm facing the tool magazine.

[0015] The automatic tool changer debugging fixture and its machine tool mechanism provided by this utility model can directly replace the tool holder installation by adjusting the tool position, eliminating the need to remove interfering parts and simplifying the process by eliminating the "disassembly-installation-reassembly" steps. Its center hole is concentric with the tool holder, ensuring that the debugging benchmark is consistent with the actual situation, thus improving accuracy from the source. The debugging ring fixture simulates a standard tool holder, forming an equivalent "tool holder-tool holder" scenario with the tool position debugging fixture, avoiding the accuracy loss caused by differences in traditional fixture structures, and is compatible with various robotic arm grippers of the same specifications, reducing reliance on special fixtures and lowering operational complexity to improve efficiency. The central shaft can be directly checked for concentricity by inserting into the center holes of the two fixtures, replacing the repeated measurement with traditional complex measuring tools, thus simplifying the process.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0026] The following is combined Figures 1 to 3 The present invention will provide a detailed description of the debugging fixture and machine tool mechanism of an automatic tool changer provided by the present invention through specific embodiments and application scenarios.

[0027] In this utility model example, such as Figure 1 and Figure 3 As shown, an automatic tool changer debugging fixture 10 and a machine tool mechanism are disclosed. The debugging fixture 10 includes a tool position debugging fixture 100, a debugging ring fixture 200, and a central shaft fixture 300. The tool position debugging fixture 100 is installed on the tool holder mounting position of the tool magazine 40 to be debugged. The tool position debugging fixture 100 has a central hole 1131, which is coaxial with the central hole 1131 of the tool holder. The debugging ring fixture 200 has the same shape and size as the tool holder. The debugging ring fixture 200 is installed on the jaw of the robotic arm 20 for tool changing on the machine tool, and the debugging ring fixture 200 is coaxial with the clamp of the robotic arm 20. The central shaft fixture 300 is installed on the central hole 1131. Both ends of the central shaft fixture 300 extend along a first direction, and one end of the central shaft fixture 300 is coaxially and movably connected to the debugging ring fixture 200.

[0028] The tool position adjustment fixture 100 is installed on the tool holder mounting position of the tool magazine 40 to be adjusted, directly replacing the original tool holder of the tool magazine 40. The installation can be completed without removing the protective plate, chain and other interfering parts on the tool magazine 40. This solves the problem of traditional fixtures requiring disassembly due to space limitations, simplifies the installation process, and provides basic installation conditions for subsequent adjustment.

[0029] The tool position adjustment fixture 100 has a center hole 1131. The center hole 1131 is coaxial with the center hole 1131 of the tool holder. The center hole 1131 serves as a reference hole during adjustment. Its coaxial design with the center hole 1131 of the tool holder ensures that the fixture can accurately simulate the axis position of the tool holder, making the adjustment reference completely consistent with the actual working state of the tool holder. This avoids calibration errors caused by the fixture's own deviation and ensures adjustment accuracy from the source.

[0030] The debugging ring fixture 200 has the same shape and size as the tool holder. By simulating the shape and size of the standard tool holder, the debugging scenario is completely equivalent to the working condition of "the tool holder being held by the robotic arm 20" during actual tool changing. This ensures that the test data can truly reflect the concentricity requirements during actual tool changing and avoids the test distortion caused by structural differences in traditional fixtures.

[0031] The debugging ring fixture 200 is installed on the jaws of the robotic arm 20 used for tool changing on the machine tool. The debugging ring fixture 200 and the clamp of the robotic arm 20 are set coaxially. On the one hand, the matching installation with the jaws of the robotic arm 20 ensures the stable fixation of the fixture. On the other hand, the coaxial design with the clamp ensures that the axis of the debugging ring is consistent with the rotation center of the robotic arm 20, providing an accurate side reference of the robotic arm 20 for concentricity detection, and further improving the debugging accuracy.

[0032] The central shaft fixture 300 is installed on the central hole 1131 and positioned with the central hole 1131 of the tool position adjustment fixture 100 as a reference to ensure that the initial position of the central shaft is consistent with the axis of the tool holder, providing a reference axis for subsequent detection of the relative position relationship between the robotic arm 20 and the tool holder.

[0033] The two ends of the central shaft fixture 300 extend along the first direction. The extension structure can cross the gap between the tool magazine 40 and the robotic arm 20, so that the central shaft can simultaneously connect the tool position adjustment fixture 100 and the adjustment ring fixture 200, forming a rigid detection shaft that runs through both, providing a physical carrier for concentricity judgment.

[0034] One end of the central shaft fixture 300 is coaxially and movably connected to the debugging ring fixture 200. The concentricity of the two can be directly judged by the movable connection. If the connection is smooth and the gap is uniform, it means that the concentricity of the tool holder and the robotic arm 20 is qualified. If the connection is difficult or the gap deviation is large, the deviation position can be quickly located by the offset direction of the central shaft, which replaces the repeated measurement of traditional complex measuring tools, simplifies the operation and improves the judgment efficiency.

[0035] This application simplifies the process by allowing the tool holder to be directly replaced by the tool position adjustment fixture 100, eliminating the need to remove interfering parts and simplifying the process by removing the "disassembly-tooling-reassembly" steps. Its center hole 1131 is concentric with the tool holder, ensuring that the adjustment benchmark matches the actual tool, thus improving accuracy from the source. The adjustment ring fixture 200 simulates a standard tool holder, forming an equivalent "tool holder-tool holder" scenario with the tool position adjustment fixture 100. This avoids accuracy loss caused by differences in traditional fixture structures and is compatible with various robotic arm 20 jaws of the same specification, reducing reliance on dedicated fixtures and lowering operational complexity to improve efficiency. The central shaft is directly inspected for concentricity by inserting into the center holes 1131 of the two fixtures, replacing repeated measurements with traditional complex measuring tools and simplifying the process. Its extended structure can quickly locate the deviation direction and quantify the deviation in the gap value, reducing manual judgment time and improving accuracy controllability and adjustment efficiency.

[0036] Reference Figure 1 According to the present invention, an automatic tool changer debugging fixture 10 is provided, wherein the central shaft fixture 300 and the debugging ring fixture 200 are coaxially connected.

[0037] It is understandable that by connecting the concentric axes, the central axis fixture 300 can maintain a coaxial reference with both the tool position adjustment fixture 100 (simulating the tool holder) and the adjustment ring fixture 200 (simulating the tool holder), forming a rigid detection chain of "tool holder side reference - central axis - robotic arm 20 side reference", which directly maps the actual concentricity relationship between the tool holder and the robotic arm 20.

[0038] Reference Figure 1 and Figure 2 According to the present invention, an automatic tool changer debugging fixture 10 is provided, and the debugging ring fixture 200 has a first end face and a second end face that are arranged opposite to each other. The first end face and the second end face are respectively flush with the end face corresponding to the clamping jaw of the robotic arm 20.

[0039] Understandably, during automatic tool changing, the robotic arm 20 needs to accurately clamp and release the tool holder. The first and second end faces of the adjustment ring fixture 200 are flush with the end faces corresponding to the clamping jaws of the robotic arm 20, providing a precise positioning reference for the robotic arm 20. When the clamping jaws of the robotic arm 20 close to clamp the adjustment ring fixture 200, it ensures accurate clamping position, just as it does during actual tool changing. This precise clamping avoids problems such as tool changing failure and tool collision caused by clamping position deviations, thus ensuring the tool changing accuracy of the automatic tool changer in subsequent actual operation.

[0040] The flush end face design allows commissioning personnel to visually observe the contact between the gripper of the robotic arm 20 and the commissioning ring fixture 200. If the end faces are completely flush, it indicates that the gripping action of the robotic arm 20 is accurate and the commissioning status is good; if there is obvious misalignment or unevenness, it indicates that the gripping position of the robotic arm 20 is deviated and needs adjustment. This intuitive judgment method facilitates timely identification and resolution of problems by commissioning personnel, improving the efficiency and accuracy of commissioning work.

[0041] Reference Figure 1 and Figure 2 According to the present invention, an automatic tool changer debugging fixture 10 is provided. The tool position debugging fixture 100 includes a fixture body 110 and a lifting rod 120. The fixture body 110 is connected to the tool sleeve mounting position through the lifting rod 120, and the center hole 1131 is opened on the fixture body 110.

[0042] Understandably, the lifting rod 120, as a connecting structure, provides a quick assembly method for the tool body 110 with the tool holder mounting position. Installation can be completed without additional modification to the tool magazine 40 structure. It adapts to the tool holder mounting position design of the tool magazine 40 to be debugged, ensuring that the tool can be stably fixed on the tool magazine 40, and replaces the tool holder to realize the establishment of the debugging benchmark.

[0043] Reference Figure 1 and Figure 2 According to the present invention, an automatic tool changer debugging fixture 10 is provided, wherein a lifting hole 1111 is provided on the fixture body 110, the lifting hole 1111 is opened along a first direction, and the lifting rod 120 passes through the lifting hole 1111.

[0044] Understandably, the lifting hole 1111 is opened along the first direction, providing a clear and fixed guide for the movement of the lifting rod 120. During the debugging of the automatic tool changer, the fixture body 110 needs to be lifted to simulate the tool changing action. The first direction is usually consistent with the lifting direction of the tool during tool changing. Through this design, the lifting rod 120 can only move linearly along the first direction under the constraint of the lifting hole 1111, thereby ensuring that the fixture body 110 can be lifted in the predetermined direction, avoiding deviation and shaking during the lifting process, realizing precise lifting operation, and making the debugging process closer to the actual tool changing condition.

[0045] Reference Figure 1 and Figure 2According to the present invention, an automatic tool changer debugging fixture 10 is provided. The fixture body 110 includes a fixed section 111, a transition section 112 and a mating section 113. The fixed section 111 is provided with a lifting hole 1111 and is connected to the lifting rod 120 through the lifting hole 1111. The transition section 112 is arc-shaped and is connected between the fixed section 111 and the mating section 113. The mating section 113 is provided with a center hole 1131.

[0046] It is understandable that the fixed section 111 serves as the connecting carrier between the tooling body 110 and the lifting rod 120. By cooperating with the lifting rod 120 through the preset lifting hole 1111, the axial and radial positions of the tooling body 110 on the tool holder mounting position can be strictly controlled, ensuring that the tooling body 110 as a whole is aligned with the reference of the tool holder mounting position.

[0047] The arc-shaped transition section 112 is mainly used to adapt to the spatial structure between the tool magazine 40 and the robotic arm 20.

[0048] As the direct load-bearing structure of the center hole 1131, the shape and size design of the mating section 113 must ensure the coaxiality accuracy between the center hole 1131 and the original center hole 1131 of the tool holder. After being connected to the fixed section 111 through the transition section 112, the mating section 113 can accurately simulate the core functional reference of the tool holder (i.e., the central axis of the tool holder installation), providing a stable insertion foundation for the central shaft tooling 300, and ensuring that the debugging reference on the tool magazine 40 side is consistent with the actual working state.

[0049] In this way, by setting the tooling body 110 into a three-section structure, the clear division of functions can not only meet the precise connection between the tooling body 110 and the tool holder mounting position, but also avoid spatial interference through the arc transition. Ultimately, it ensures that the center hole 1131 of the mating section 113 is in the optimal position for docking with the debugging ring tooling 200 of the robotic arm 20, thereby improving the adaptability and detection accuracy of the entire debugging tooling.

[0050] Reference Figure 1 and Figure 2 According to the present invention, an automatic tool changer debugging fixture 10 is provided, the fixture body 110 is arranged in a stepped manner, and the fixture body 110 is arranged in an upward trend from the mating section 113 to the fixing section 111.

[0051] Understandably, the stepped-up tooling body 110 design creates a spatial hierarchy between the mating section 113 and the fixed section 111, providing operators with a better viewing angle. During debugging, operators need to observe the tool changing action, the movement status of various components, and the data fed back by sensors. The stepped-up tooling body 110 makes the structure and movement of different parts more clearly visible, allowing operators to observe from different angles and promptly identify problems during debugging, such as tool jamming or component collisions, for timely adjustments and repairs.

[0052] Reference Figure 1 and Figure 2 According to the debugging fixture 10 of the automatic tool changer provided by this utility model, there are two lifting rods 120. The fixed section 111 is provided with two lifting holes 1111 arranged side by side along the second direction, and the two lifting rods 120 are respectively inserted into the two lifting rods 120.

[0053] Understandably, the two lifting rods 120 are arranged side by side along the second direction (perpendicular to the first direction, i.e., transverse), forming a stable "dual-axis positioning" structure through two-point support, which can effectively limit the radial rotation and offset of the tooling body 110 after installation. Compared with the single-point support of a single lifting rod 120, the design of double lifting rods 120 with double lifting holes 1111 can eliminate the rotational degree of freedom of the tooling body 110 around the axis of the lifting rods 120, ensuring that the relative angle between the center hole 1131 (fitting section 113) of the tooling body 110 and the tool holder mounting position is fixed, avoiding the reference offset caused by tool rotation, and providing a stable spatial posture for concentricity detection.

[0054] Reference Figure 3 This utility model also provides a machine tool mechanism, which includes a tool magazine 40, a robot arm, an ejection mechanism 30, and an adjustment fixture 10 for the automatic tool changer as described above. The robot arm is mounted on the output shaft of the ejection mechanism 30. The tool position adjustment fixture 100 is mounted on the tool sleeve mounting position to be adjusted in the tool magazine 40. The central shaft fixture 300 is connected to the tool position adjustment fixture 100. The adjustment ring fixture 200 is mounted in the jaw of the robot arm 20 facing the tool magazine 40.

[0055] The tool positioning adjustment fixture 100 is installed on the tool holder mounting position of the tool magazine 40 to be adjusted, providing a precise positioning reference for the entire adjustment process. The tool magazine 40 is a key component for storing tools. By accurately installing the adjustment fixture on the tool holder mounting position, the actual position of the tool in the tool magazine 40 can be simulated. When adjusting the tool positioning accuracy of the tool magazine 40, the adjustment fixture can serve as a standard reference, ensuring that the position of each tool holder in the tool magazine 40 accurately corresponds to the predetermined coordinates, thereby guaranteeing the accuracy of subsequent tool picking and placing actions by the robotic arm.

[0056] The robotic arm is mounted on the output shaft of the ejection mechanism 30, which provides power and motion control for the robotic arm. During tool changing and debugging, the ejection mechanism 30 can precisely control the extension and retraction of the robotic arm according to a preset program. For example, when the robotic arm needs to grab a tool from the tool magazine 40, the ejection mechanism 30 pushes the robotic arm to the designated position so that its grippers can accurately grasp the tool; after the tool change is completed, the ejection mechanism 30 retracts the robotic arm, completing the reset of the entire tool changing action. This tight connection ensures the stability and accuracy of the robotic arm's movement, which is an important guarantee for realizing the automatic tool changing function.

[0057] The central axis fixture 300 is connected to the tool position adjustment fixture 100, and the adjustment ring fixture 200 is installed in the jaws of the robotic arm 20 facing the tool magazine 40. These two components together constitute the key links in the interactive adjustment between the robotic arm and the tool magazine 40. The central axis fixture 300 provides precise positioning and guidance for the robotic arm's gripping action, ensuring that the robotic arm's jaws can accurately align with the center position of the tool. The adjustment ring fixture 200 can be used to detect the gripping force and positional accuracy of the robotic arm's jaws. By observing the cooperation between the adjustment ring fixture 200 and the central axis fixture 300 during the adjustment process, the operator can promptly identify problems in the robotic arm's gripping action and make corresponding adjustments and optimizations, thereby achieving high-precision interactive adjustment between the robotic arm and the tool magazine 40.

[0058] The debugging method of the debugging fixture 10 of the automatic tool changer of this utility model is as follows: Remove tool holder No. 1 and install tool position adjustment fixture 100 into the position of tool holder No. 1; Install the test ring fixture 200 into the chuck of the robotic arm 20 on the side facing the tool magazine 40; The universal dial indicator holder is attached to the base of the tool magazine 40 by the magnetic attraction of the magnetic base, and the dial indicator is attached to the side of the robotic arm 20. Control the ejection mechanism 30 to eject and retract, and adjust the parallelism of the side of the robotic arm 20 and the ejection direction until it is qualified; Alternately control the rotation of the tool magazine 40 and the movement of the ejection mechanism 30, while using the central shaft fixture 300 to measure the coaxiality of the center hole 1131 of the tool position adjustment fixture 100 and the adjustment ring fixture 200, and repeatedly adjust until a suitable tool changing position is found. Remove the tool position adjustment fixture 100 and the adjustment ring fixture 200, and reinstall the No. 1 tool holder back into its original position.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
