Description

Technical Field

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

[0002] Before machining a part, tool setting is a crucial step in ensuring machining accuracy and efficiency. The purpose of tool setting is to determine the position of the tool relative to the workpiece, ensuring that the tool tip or reference point is aligned with the workpiece coordinate system. The accuracy of tool setting directly affects the dimensions and geometry of the machined part. Precise tool setting ensures that the tool can accurately cut the workpiece according to the programmed path, avoiding dimensional deviations and shape errors. It avoids remapping or adjustments due to incorrect tool positioning, reducing machining time and improving production efficiency. Therefore, tool setting must be performed before machining to ensure the accuracy of the tool position, laying a solid foundation for subsequent machining.

[0003] Currently, there are two methods for tool setting in CNC machine tools: tool setting with a tool setter and manual tool setting. However, tool setters are expensive and mostly used in high-end CNC machine tools. Manual tool setting, on the other hand, relies on the operator's experience and skill, and is prone to errors and low tool setting accuracy. Therefore, how to design a tool setting detection component that balances economy and measurement accuracy has become an urgent problem to be solved in the current technology. Utility Model Content

[0004] This invention provides a tool setting detection component and a machining center having the same, to solve the problem in the prior art of how to combine the economy and accuracy of a tool setting detection component.

[0005] According to one aspect of the present invention, a tool setting detection assembly is provided, comprising: a base having a first connecting portion located at the center of an end face of the base; a top cover covering the base, the top cover having a body and a side plate, the surface of the body away from the base being a detection surface for contacting the test piece, the side plate being located on the side of the body near the base and surrounding the outer periphery of the base, a movable gap between the top cover and the base, the top cover having a second connecting portion located on the side of the body facing the base and at the center of the end face of the body near the base, the first connecting portion and the second connecting portion being ball-jointed, the top cover being able to swing relative to the base in the height direction through the cooperation of the first connecting portion and the second connecting portion; and a plurality of displacement sensors evenly spaced along the circumference on the base, the displacement sensors being able to detect the offset of the side plate when the top cover swings.

[0006] Furthermore, the top cover has an offset position and an initial position relative to the base in the height direction. The tool setting detection assembly also includes an elastic reset member disposed between the base and the top cover. The elastic reset member is used to provide an elastic force to the top cover to move to the initial position.

[0007] Furthermore, the outer contour of the base is adapted to the outer contour of the top cover.

[0008] Furthermore, the sidewall of the base is provided with multiple first end corners at circumferential intervals. The multiple first end corners are symmetrically arranged on the base with respect to the center of the base. Displacement sensors are provided in one-to-one correspondence with the first end corners. The side plate has multiple second end corners, which are provided in one-to-one correspondence with the first end corners. The displacement sensors are used to detect the distance to the second end corner corresponding to the displacement sensor.

[0009] Furthermore, the base is provided with multiple mounting structures, each corresponding to a displacement sensor, and the mounting structures are used to fix the position of the displacement sensor on the base.

[0010] Furthermore, the mounting structure includes a mounting groove and a guide hole. The displacement sensor is installed in the mounting groove, one end of the guide hole is connected to the mounting groove, and the other end of the guide hole is connected to the outside. The displacement sensor detects the distance to the side plate through the guide hole.

[0011] Furthermore, the displacement sensor includes a dial indicator, which includes a body, a test rod, and a spring. The test rod is telescopically mounted on the body and has a test end and a connecting end that are positioned opposite each other. The spring is sleeved on the test rod, with the test end located on the outside of the body and used to abut against the side plate. The spring can provide an elastic force to the test rod to move away from the body.

[0012] Furthermore, multiple test protrusions are provided on the inner wall of the side plate, and each test protrusion corresponds to a displacement sensor. The test end of the test rod abuts against the corresponding test protrusion.

[0013] Furthermore, the first connecting part is a support column, which is located at the center of the end face of the base. The end of the support column away from the base is a spherical structure. The second connecting part includes a limiting groove, which is located at the center of the end face of the body near the base. The spherical structure is rotatably located in the limiting groove.

[0014] According to another aspect of the present invention, a machining center is provided, which includes a spindle, a cutting tool, a worktable, a control system, and the aforementioned tool setting detection component. The tool setting detection component is disposed on the worktable. The spindle is driven and connected to the cutting tool. The control system is electrically connected to multiple displacement sensors of the spindle and the tool setting detection component respectively. The spindle drives the cutting tool to abut against the detection surface of the tool setting detection component. The multiple displacement sensors can detect the position information of the cutting tool. The control system controls the spindle to work according to the position information to perform zeroing processing on the cutting tool.

[0015] By applying the technical solution of this utility model, a first connecting part is set at the center of the base and ball-jointed with the second connecting part of the top cover, allowing the top cover to swing flexibly in the height direction. When the tool contacts the detection surface, if the tool is not at the center of the detection surface, the top cover will shift due to pressure. At this time, displacement sensors evenly distributed on the base can detect the offset of the top cover side plate, thereby detecting the position information of the tool relative to the workpiece. The operator can adjust the tool to a suitable position based on the offset data until the tool setting operation is completed. The tool setting detection component proposed in this application not only avoids the dependence and error of traditional manual tool setting, but also reduces the cost of using expensive tool setting instruments, combining economy and accuracy.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0043] like Figure 1 and Figure 2As shown, this utility model embodiment provides a tool setting detection component, which includes a base 10, a top cover 20 and a plurality of displacement sensors 40. The base 10 has a first connecting part 31, which is located at the center of the end face of the base 10. A top cover 20 is mounted on a base 10. The top cover 20 has a body 21 and a side plate 22. The surface of the body 21 away from the base 10 is a detection surface 211, which is used to abut against the test piece. The side plate 22 is located on the side of the body 21 closest to the base 10 and surrounds the outer periphery of the base 10. There is a movable gap between the top cover 20 and the base 10. The top cover 20 has a second connecting part 32, which is located on the side of the body 21 facing the base 10 and is located at the center of the end face of the body 21 closest to the base 10. The first connecting part 31 and the second connecting part 32 are ball-jointed. The top cover 20 can swing relative to the base 10 in the height direction through the cooperation of the first connecting part 31 and the second connecting part 32. Multiple displacement sensors 40 are evenly distributed on the base 10 in the circumferential direction. When the top cover 20 swings, the displacement sensors 40 can detect the offset of the side plate 22.

[0044] By applying the technical solution of this utility model, a first connecting part 31 is provided at the center of the base 10 and ball-jointed with the second connecting part 32 of the top cover 20, allowing the top cover 20 to swing flexibly in the height direction. When the tool contacts the detection surface 211, if the tool is not at the center of the detection surface 211, the top cover 20 will shift due to pressure. At this time, the displacement sensors 40, which are evenly distributed on the base 10, can detect the offset of the side plate 22 of the top cover 20, and thus detect the position information of the tool relative to the workpiece. The operator can adjust the tool to a suitable position based on the offset data until the tool setting operation is completed. The tool setting detection component 103 proposed in this application not only avoids the dependence and error of traditional manual tool setting, but also reduces the cost of using expensive tool setting instruments, combining economy and accuracy.

[0045] Specifically, in this embodiment, four displacement sensors 40 are provided, and the four displacement sensors 40 are respectively located at the four corners of the base 10. This allows the displacement sensors 40 to detect the displacement information of the top cover 20 from all directions and multiple angles, further increasing the accuracy of the tool setting detection component.

[0046] like Figure 3As shown, the top cover 20 has an offset position and an initial position relative to the base 10 in the height direction. The tool setting detection assembly also includes an elastic reset member 50. Specifically, the elastic reset member 50 is disposed between the base 10 and the top cover 20, and is used to provide an elastic force to the top cover 20 to move to the initial position. By setting the elastic reset member 50, it is ensured that the top cover 20 can be stably in the initial position, i.e., the tool setting zero point position, when no external force is applied. This provides an accurate reference point for the tool setting process and enhances the stability of tool setting detection. Furthermore, the elastic force of the elastic reset member 50 can reset the top cover 20 after the tool setting pressure is released, avoiding errors in the next tool setting operation caused by deformation or positional displacement of the top cover 20, thereby ensuring the accuracy and consistency of each tool setting detection operation.

[0047] Specifically, at least one elastic reset element 50 is provided to ensure that the top cover 20 is in its initial position under the elastic force of the elastic reset element 50. In this embodiment, the elastic reset element 50 is a spring, and four elastic reset elements 50 are provided, evenly distributed on the base 10. One elastic reset element 50 is provided between two adjacent displacement sensors 40, and both ends of each elastic reset element 50 are connected to the base 10 and the top cover 20, respectively. Through the above arrangement, the force generated when the tool touches the top cover 20 can be effectively dispersed, effectively reducing local stress concentration, avoiding deformation or damage to the top cover 20, extending the service life of the device, and ensuring that the top cover 20 can be effectively reset after being touched by the tool.

[0048] In this embodiment, the outer contour of the base 10 is adapted to the outer contour of the top cover 20. This matching shape provides sufficient support area, allowing the pressure applied by the tool to be distributed more evenly on the top cover 20, reducing localized excessive stress and thus protecting the top cover 20 from damage. Furthermore, the matching contour structure ensures sufficient space for the top cover 20 to move relative to the base 10, while the base 10 provides some restraint on the top cover 20, preventing excessive deflection and damage.

[0049] The base 10 can have a circular or polygonal outline, or other centrally symmetrical structures. In this embodiment, the sidewalls of the base 10 are circumferentially spaced with multiple first end angles 60, which are symmetrically arranged around the center of the base 10. Displacement sensors 40 are correspondingly arranged with each of the first end angles 60. The side plate 22 has multiple second end angles 70, which are also correspondingly arranged with each of the first end angles 60. The displacement sensors 40 are used to detect the distance to the second end angle 70 corresponding to them. By providing multiple centrally symmetrically distributed first end angles 60 on the sidewalls of the base 10 and correspondingly providing multiple second end angles 70 on the side plate 22 of the top cover 20, the displacement sensors 40 can correspond one-to-one with both the first end angles 60 and the second end angles 70. This design ensures that during tool setting detection, when the tool touches the top cover 20, the relative distance between the second end corner 70 on its side plate 22 and the first end corner 60 of the base 10 changes. The displacement sensor 40 can immediately detect the minute change in distance between the corresponding end corners, thus accurately capturing the tool's displacement relative to its initial position. This design not only improves the sensitivity and accuracy of tool setting detection but also ensures the stability and reliability of the detection process. In this embodiment, four first end corners 60 are provided, evenly distributed at the four corners of the base 10.

[0050] Specifically, the base 10 is provided with multiple mounting structures 80, each corresponding to a displacement sensor 40. The mounting structures 80 are used to fix the position of the displacement sensor 40 on the base 10. By using the mounting structures 80, the displacement sensor 40 can be securely connected to the base 10. This ensures the stability and accuracy of the displacement sensor 40 during the tool setting detection process, avoids positional changes of the displacement sensor 40 due to vibration or external forces, thereby eliminating measurement errors and further increasing the accuracy and stability of the tool setting detection component.

[0051] Specifically, the mounting structure 80 includes a mounting groove 81 and a guide hole 82. The displacement sensor 40 is disposed within the mounting groove 81. One end of the guide hole 82 communicates with the mounting groove 81, and the other end communicates with the outside. The displacement sensor 40 detects the distance to the side plate 22 through the guide hole 82. The mounting groove 81 provides an embedding space for the displacement sensor 40, ensuring that the displacement sensor 40 is securely installed without unnecessary contact or interference with other structures of the base 10. This not only protects the displacement sensor 40 from damage caused by collisions or compression but also optimizes the internal spatial layout of the base 10, making the entire tool setting detection assembly more compact. The guide hole 82 provides a detection channel between the displacement sensor 40 and the side plate 22 of the top cover 20, ensuring that the displacement sensor 40 can accurately detect the minute displacement of the side plate 22 relative to the base 10.

[0052] Specifically, the mounting slot 81 and the displacement sensor 40 can be connected by interference fit, bolts, or adhesive bonding. In this embodiment, the mounting slot 81 and the displacement sensor 40 are connected by bolts to facilitate the disassembly of the displacement sensor 40 from the mounting slot 81, and to facilitate the maintenance, repair, and replacement of the displacement sensor 40.

[0053] Furthermore, the displacement sensor 40 can be a laser sensor, a mechanical sensor, etc. In this embodiment, the displacement sensor 40 is a dial indicator 41, which includes a main body 42, a test rod 43, and a spring 44. The test rod 43 is telescopically mounted on the main body 42 and has a test end and a connecting end that are arranged opposite to each other. The spring 44 is sleeved on the test rod 43, with the test end located outside the main body 42 and used to abut against the side plate 22. The spring 44 can provide an elastic force to the test rod 43 to move away from the main body 42.

[0054] By fitting a spring 44 onto the test rod 43, the spring 44 consistently applies an elastic force that keeps the test rod 43 away from the main body 42 and in its original position. This design ensures that, in the absence of external force, the test end of the test rod 43 can accurately align with its preset monitoring position, namely the second end angle 70 on the side plate 22. When the top cover 20 shifts due to contact with the tool, the test end contacts the side plate 22 and displaces accordingly. The dial indicator 41 can instantly record and report this change, achieving high-precision detection of the relative position of the tool. Furthermore, the restoring force provided by the spring 44 ensures that the test rod 43 can quickly reset after the test, ready for the next measurement, effectively improving the consistency and accuracy of each measurement of this tool-setting detection assembly.

[0055] Specifically, multiple test protrusions 90 are provided on the inner wall of the side plate 22. Each test protrusion 90 corresponds to a displacement sensor 40, and the test end of the test rod 43 abuts against the corresponding test protrusion 90. The test protrusion 90 serves as a fixed reference point, ensuring that even under slight vibrations or changes in ambient temperature during the operation of the machining center, the displacement sensor 40 can still perform displacement measurement stably and reliably, avoiding measurement errors caused by unstable contact points or inaccurate positioning.

[0056] like Figure 4As shown, the first connecting part 31 is a support column, located at the center of the end face of the base 10. The end of the support column away from the base 10 has a spherical structure. The second connecting part 32 includes a limiting groove, located at the center of the end face of the body 21 near the base 10. The spherical structure is rotatably disposed within the limiting groove. By designing the first connecting part 31 as a support column at the center of the end face of the base 10, and setting its end away from the base 10 as a spherical structure, while setting the second connecting part 32 as a limiting groove adapted to the spherical structure, and fixing it at the center of the body 21 of the top cover 20, the spherical structure and the limiting groove can rotate relative to each other. This connection structure allows the top cover 20 and the base 10 to be center-aligned and have free rotation capability. Furthermore, this allows the top cover 20 to deflect flexibly and unimpeded after being touched by a tool, thereby accurately reflecting the actual positional deviation of the tool relative to the tool setting zero point.

[0057] like Figure 5 As shown, in another embodiment of this application, a machining center is provided. The machining center includes a spindle 100, a cutting tool, a worktable 102, a control system, and the aforementioned tool setting detection component. The tool setting detection component 103 is disposed on the worktable 102. The spindle 100 is driven and connected to the cutting tool. The control system is electrically connected to multiple displacement sensors 40 of the spindle 100 and the tool setting detection component 103. The spindle 100 drives the cutting tool to abut against the detection surface 211 of the tool setting detection component 103. The multiple displacement sensors 40 can detect the position information of the cutting tool. The control system controls the spindle 100 to work according to the position information to perform zeroing processing on the cutting tool. Specifically, the machining center has a tool magazine 101, in which the cutting tool is placed.

[0058] In this embodiment, when the machining center initiates the tool setting program, the spindle 100, under the command of the control system, moves the tool toward the tool setting detection assembly on the worktable 102. The tool moves downward until its tip touches the detection surface 211. At this time, multiple displacement sensors 40 within the tool setting detection assembly respond. By contacting the test boss 90, they acquire the overall offset of the tool, collect and convert the offset data of the tool relative to the zero point position, and transmit this offset data to the control system via electrical connection. Based on the received offset data, the control system analyzes the actual position deviation of the tool and then adjusts the motion parameters of the spindle 100, such as position compensation and rotation angle, to achieve automatic zeroing of the tool.
