Description

Technical Field

[0001] This application relates to the field of cutting tool inspection technology, and in particular to a cutting tool inspection device and processing equipment. Background Technology

[0002] Currently, existing tool inspection devices have relatively limited detection functions, making it impossible for operators to directly assess the condition of the tools. For example, most existing tool inspection devices can only detect the length of the tool. When the bottom edge of the tool is worn or chipped, it does not affect the device's ability to detect the tool's length. This allows the device to record the tool's length in the machining program during the inspection process, leading to the machine tool using the damaged tool during the machining of the workpiece, thus directly impacting the workpiece yield. Utility Model Content

[0003] In view of this, this application provides a tool inspection device and processing equipment to solve the technical problem of the limited inspection function of tool inspection devices in the prior art.

[0004] This application provides a tool detection device, which includes a base, a first support, a second support, a probe, and a detection element. The first support and the second support are connected to the same side of the base and are spaced apart along a first direction. The first support and the second support are respectively provided with a first through hole and a second through hole extending along the first direction. At least a portion of the probe is located in the first through hole, and at least a portion of the detection element is located in the second through hole, and is fixedly connected to the second support. The probe and the detection element are center-aligned.

[0005] The probe is mounted on the first bracket via a connector, which includes a ball and a rod connected together. The ball is rotatably connected to the probe, and the rod is fixedly connected to the first bracket, so that there is a first gap between the probe and the sidewall of the first through hole.

[0006] In this embodiment, the probe is used to contact the tool to be inspected and to move under the drive of the tool. By movably connecting the probe to the first support, the probe has a high degree of freedom to meet the multi-functional inspection requirements of the tool inspection device. The detection element is used to detect the displacement of the probe. By fixing the detection element to the second support, the detection element has high installation stability, thereby improving the detection accuracy and the overall accuracy of the tool inspection device's results. Furthermore, by aligning the probe and the detection element along the first direction, the projections of the probe's axis and the detection element's axis coincide along the first direction, ensuring that the initial displacement of the probe is zero. This allows the detection element to accurately measure the displacement of the probe after it has moved, improving the sensitivity of the detection and further enhancing the detection accuracy, thus ensuring the accuracy of the tool inspection device's results.

[0007] Meanwhile, the probe is mounted on the first bracket via a connector, and a first gap exists between the outer surface of the probe and the sidewall of the first through hole along the second and third directions. This first gap serves as the probe's movement space, allowing it to rotate around the ball as a fulcrum in the second direction, the third direction, or the first direction after contact with the tool to be inspected. This enables the probe to achieve multi-directional displacement, allowing the tool inspection device to inspect the same tool from different directions and obtain different parameters through displacement in different directions. This allows for a more accurate deduction of the tool's working state, improving the versatility of the tool inspection device's detection functions.

[0008] In one possible implementation, the first bracket has a first opening at one end away from the base, the first opening communicating with the first through hole, and the tool detection device further includes a top cover connected to the side of the first bracket and the second bracket away from the base to block the first opening.

[0009] In one possible implementation, the tool detection device further includes a third bracket mounted on the base and located between the first bracket and the second bracket.

[0010] The third bracket is provided with a third through hole extending along the first direction, at least a portion of the probe is located in the third through hole, and the tool detection device further includes an elastic element, through which the probe is elastically connected to the third bracket.

[0011] In one possible implementation, the sidewall of the third through hole is provided with a plurality of first mounting grooves spaced apart circumferentially, and the sidewall of the probe is provided with a plurality of second mounting grooves spaced apart circumferentially, with the plurality of first mounting grooves and the plurality of second mounting grooves being provided in a one-to-one correspondence.

[0012] There are multiple elastic elements. One end of each elastic element is located in the first mounting groove and connected to the third bracket. The other end of each elastic element is located in the second mounting groove and connected to the probe.

[0013] In one possible implementation, the third bracket is further provided with a recess on either side of the first direction, the recess communicating with each of the second mounting slots, and the tool detection device further includes a fixing member, at least a portion of which is located within the recess to block each of the second mounting slots.

[0014] In one possible implementation, the third support has a second gap L2 between it and the first support, and the third support has a third gap L3 between it and the second support, and L2 and L3 satisfy 0.2≤L2 / L3≤0.8; wherein L2 satisfies 10mm≤L2≤20mm, and L3 satisfies 25mm≤L3≤35mm.

[0015] In one possible implementation, the first gap is L1, and L1 satisfies 1mm≤L1≤3mm.

[0016] In one possible implementation, along the first direction, there is a fourth gap L4 between the probe and the detection element, and L4 satisfies 1mm≤L4≤1.5mm.

[0017] In one possible implementation, the detector includes a detector part and a main body part. The detector part is connected to the end of the main body part away from the detector part along a first direction. The main body part is connected to the ball part. The main body part includes a first mating part and a second mating part. Both the first mating part and the second mating part are provided with receiving grooves. The two receiving grooves form a receiving space for accommodating the ball part.

[0018] This application also provides a processing device, which includes a work platform, a machining spindle, and a tool detection device. Along a third direction, the machining spindle is located above the work platform, and a tool to be detected is disposed on the side of the machining spindle facing the work platform. The tool detection device is mounted on the work platform, and the tool detection device is any of the tool detection devices described above, used to detect the working state of the tool to be detected.

[0019] In this embodiment, the top cover is provided with a positioning ring, which has a fourth through hole extending along a third direction. The center of the fourth through hole coincides with the projection of the axis of the tool detection device along the third direction. Since the probe is installed in the first through hole of the first bracket and the detection element is installed in the second through hole of the second bracket, the probe and the detection element are aligned along the center of the first direction, allowing the axis of the probe, the axis of the detection element, and the center of the second through hole to be aligned along the first direction, thereby forming the axis of the tool detection device extending along the first direction. When the first gap between the probe and the sidewall of the first through hole is equal everywhere along the second and third directions, the axis of the probe, the center of the first through hole, the axis of the detection element, and the center of the second through hole can be aligned along the first direction, also forming the axis of the tool detection device extending along the first direction. Therefore, in this embodiment, by setting the center of the fourth through hole to coincide with the projection of the axis of the tool detection device along the third direction, the tool detection device can be positioned, which is beneficial for improving the positioning accuracy of the tool detection device.

[0020] The machining equipment also includes a control system, which is electrically or signal-connected to the machining spindle and the tool detection device. The machining spindle is equipped with a probe, and the top cover of the tool detection device has a positioning ring with a fourth through hole. During positioning, the operator can manually control the movement of the machining spindle, thereby moving the probe to insert it into the fourth through hole for positioning. Specifically, the operator first controls the probe to extend into the fourth through hole along a third direction, and then controls the probe to move along a first direction and a second direction, allowing the probe to make multiple contacts with the sidewall of the fourth through hole. The coordinates of each contact are recorded so that the center coordinates of the fourth through hole can be calculated using multiple sets of coordinate data. Simultaneously, the center coordinates of the fourth through hole are set as the reference coordinates (X0, Y0) and recorded in the control system to achieve the positioning of the tool detection device.

[0058] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0059] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0060] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0061] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0062] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0063] Embodiments of this application provide a tool detection device, installed on the work platform of a machining equipment, for detecting the tool to be inspected, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this application, the length direction of the tool detection device is defined as the first direction x, the width of the tool detection device is defined as the second direction y, and the height direction of the tool detection device is defined as the third direction z.

[0064] Specifically, the tool detection device includes a base 8, a first bracket 1, a second bracket 2, a probe 4, and a detection element 5. The first bracket 1 and the second bracket 2 are mounted on the same side of the base 8 along a third direction z and are spaced apart along a first direction x. The first bracket 1 and the second bracket 2 are respectively provided with a first through hole 11 and a second through hole 21 extending along the first direction x. The probe 4 and the detection element 5 are respectively mounted on the first bracket 1 and the second bracket 2, wherein at least a portion of the probe 4 is located within the first through hole 11, and at least a portion of the detection element 5 is located within the second through hole 21, and are fixedly connected to the second bracket 2. The probe 4 and the detection element 5 are aligned at their centers along the first direction x.

[0065] In this embodiment, the probe 4 is used to contact the tool to be inspected and to move under the drive of the tool. By movably connecting the probe 4 to the first bracket 1, the probe 4 can have a high degree of freedom to meet the multi-functional inspection requirements of the tool inspection device. The detector 5 is used to detect the displacement of the probe 4. By fixing the detector 5 to the second bracket 2, the detector 5 can have high installation stability, thereby improving the detection accuracy of the detector 5 and the accuracy of the inspection results of the tool inspection device. Furthermore, by aligning the probe 4 and detector 5 along the first x-direction, the projections of the axis of the probe 4 and the axis of the detector 5 can coincide along the first x-direction, ensuring that the displacement of the probe 4 is zero in the initial state. This allows the detector 5 to accurately measure the displacement of the probe 4 after it moves, which helps to improve the detection sensitivity of the detector 5 and further improves the detection accuracy, thus ensuring the accuracy of the inspection results of the tool inspection device.

[0066] The detection element 5 can be a displacement sensor, and the processing equipment can also include a processing spindle and a control system. The processing spindle is equipped with a tool to be tested, and the control system can be electrically or signal-connected to the detection element 5 so as to determine whether the displacement of the detection element 4 is within a preset range based on the detection result of the detection element 5, thereby determining whether the tool to be tested meets the working conditions.

[0067] Specifically, the tool to be tested can move towards the tool detection device under the drive of the machining spindle, so that the tool to be tested can come into contact with the detector 4 and drive the detector 4 to move. The detector 5 can detect the displacement of the detector 4 in real time and transmit the detection result to the control system in real time, so that the control system can determine whether the displacement of the detector 4 is within the preset range based on the detection result of the detector 5, thereby determining whether the tool meets the working conditions.

[0068] More specifically, when the control system determines that the displacement of the probe 4 is within the preset range, the tool meets the working conditions, and the control system can control the machining spindle to move the tool to the machining area so that the workpiece to be machined can be machined by the tool; when the control system determines that the displacement of the probe 4 is not within the preset range, the tool does not meet the working conditions, and the control system can control the machining spindle to move the tool to the maintenance area so that the staff can repair or replace the tool.

[0069] Meanwhile, the tool detection device may also include a connector 6, and the probe 4 is mounted on the first bracket 1 through the connector 6. The connector 6 includes a ball part 61 and a rod part 62 connected together. The rod part 62 is connected to the first bracket 1 so that there is a first gap between the probe 4 and the side wall of the first through hole 11. The ball part 61 is connected to the probe 4 so that the probe 4 can move relative to the first bracket 1 in the second direction y and / or the third direction z.

[0070] Specifically, the probe 4 is mounted on the first bracket 1 via the connector 6, and has a first gap between its outer surface and the sidewall of the first through hole 11 along the second direction y, the third direction z, and the second direction z. This first gap serves as the movement space for the probe 4, allowing it to rotate around the ball 61 as a fulcrum along the second direction y, the third direction z, or the first direction x after contacting the tool to be detected. This enables the probe 4 to achieve multi-directional displacement, allowing the tool detection device to detect the same tool from different directions and obtain different parameters through displacement in different directions. This allows for a more accurate deduction of the working state of the tool, improving the versatility of the tool detection device's detection functions.

[0071] In addition, a third mounting groove 111 is provided on the side wall of the first through hole 11. One end of the rod 62 is connected to the ball 61, and the other end of the rod 62 is connected to the third mounting groove 111 to realize the fixed connection between the connector 6 and the first bracket 1.

[0072] Specifically, along the third direction z, at least a portion of the rod 62 can extend out of the third mounting groove 111, so that there is at least a partial distance between the ball 61 and the side wall of the first through hole 11, so as to realize the movable connection between the probe 4 and the ball 61, thereby enabling the probe 4 to move within the first through hole 11 with the ball 61 as the fulcrum.

[0073] In one possible implementation, the ball portion 61 and the rod portion 62 are integrally formed, which helps to improve the overall structural stability of the connector 6, thereby providing effective support for the detector 4 and ensuring the installation reliability of the detector 4.

[0074] In one specific implementation, such as Figure 4 As shown, the first gap is L1, and L1 satisfies 1mm≤L1≤3mm.

[0075] In this embodiment of the application, the first gap L1 can specifically be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, etc.

[0076] When the first gap L1 is too small (e.g., L1 is less than 1 mm), the outer surface of the probe 4 is too close to the sidewall of the first through hole 11 along the second direction y and the third direction z. This results in a small range of motion for the probe 4, making it easy for its displacement to exceed its range of motion during the detection of the tool, thus causing the measurement of the tool detection device to fail. Simultaneously, the probe 4 is also prone to contact with the sidewall of the first through hole 11 under the drive of the tool, posing a risk of damage to the probe 4.

[0077] When the first gap L1 is too large (e.g., L2 is greater than 3mm), the outer surface of the probe 4 is too far from the side wall of the first through hole 11 along the second direction y and the third direction z. Although this makes the range of motion of the probe 4 larger, since most tool detection devices are installed near the machining platform, chips and other impurities on the machining platform can easily enter the interior of the tool detection device through the first gap, which poses a risk of contaminating or damaging the internal components of the tool detection device.

[0078] Therefore, when the first gap L1 satisfies 1mm≤L1≤3mm, the distance between the outer surface of the probe 4 and the sidewall of the first through hole 11 along the second direction y and the third direction z is moderate, thus ensuring that the probe 4 has a range of motion that meets its displacement requirements, which is beneficial to improving the accuracy of the tool detection device. At the same time, it also avoids the risk of chips and other impurities entering the tool detection device through the first gap and causing contamination or damage to internal components, which is beneficial to improving the stability and reliability of the tool detection device during operation, extending its service life, and reducing its maintenance costs.

[0079] In one specific implementation, such as Figure 2 , Figure 7 and Figure 8 As shown, the detector 4 includes a detector part 41 and a main body part 42. The detector part 41 is connected to the end of the main body part 42 away from the detector 5 along the first direction x. The main body part 42 is connected to the ball part 61. The main body part 42 includes a first mating part 421 and a second mating part 422. Both the first mating part 421 and the second mating part 422 are provided with a receiving groove 423. The two receiving grooves 423 form a receiving space for receiving the ball part 61.

[0080] In this embodiment, the detector 4 includes a detector part 41 and a main body part 42 connected together. The detector part 41 is used to contact the tool to be detected and drive the main body part 42 to rotate relative to the connector 6 under the drive of the tool to be detected. The main body part 42 is used to be movably connected to the connector 6.

[0081] Specifically, the main body 42 includes a first mating part 421 and a second mating part 422. The first mating part 421 and the second mating part 422 can be detachably connected along the second direction y to realize the assembly or disassembly of the main body 42, so as to maintain or replace the detector 4, which helps to reduce the maintenance cost of the tool detection device.

[0082] Meanwhile, both the first mating part 421 and the second mating part 422 are provided with receiving grooves 423. The receiving grooves 423 are hemispherical structures, so that after the first mating part 421 and the second mating part 422 are assembled, the two hemispherical receiving grooves 423 can form a spherical receiving space to accommodate the ball part 61 of the connector 6, thereby realizing the movable connection between the probe 4 and the connector 6. Then, after the probe 4 touches the tool to be detected, it can rotate along the second direction y, or along the third direction z, or around the first direction x, with the ball part 61 as the fulcrum, which is beneficial to improving the diversity of detection functions of the tool detection device.

[0083] More specifically, both the first mating part 421 and the second mating part 422 are provided with a second opening 424. The second opening 424 is located on the side of the receiving groove 423 along the third direction z close to the connector 6 and communicates with the receiving groove 423, so that after the first mating part 421 and the second mating part 422 are assembled, the two second openings 424 can form a fifth through hole (not shown in the figure) for receiving the rod part 62. Along the first direction x and the second direction y, there is a fifth gap (not shown in the figure) between the outer surface of the rod part 62 and the side wall of the fifth through hole, so as to provide the probe 4 with the moving space relative to the connector 6, thereby enabling the probe 4 to rotate along the second direction y with the ball part 61 as the fulcrum, or rotate along the third direction z, or rotate around the first direction x.

[0084] In one possible implementation, the main body 42 may include a first mating part 421 and a second mating part 422 with the same structure, or it may include a first mating part 421 and a second mating part 422 with different structures.

[0085] When the first mating part 421 and the second mating part 422 have the same structure, the first mating part 421 and the second mating part 422 can be processed simultaneously, which helps to simplify the production process of the main body part 42 and improve the production efficiency of the main body part 42.

[0086] When the structures of the first mating part 421 and the second mating part 422 are different, such as Figure 2 , Figure 7 and Figure 8 As shown, the first mating part 421 is provided with a fourth mounting groove 421b, and the receiving groove 423 of the first mating part 421 is provided on the bottom wall of the fourth mounting groove 421b, and the fourth mounting groove 421b communicates with the receiving groove 423 of the first mating part 421. The fourth mounting groove 421b is used to receive the second mating part 422, and after the first mating part 421 and the second mating part 422 are assembled, the receiving groove 423 of the first mating part 421 and the receiving groove 423 of the second mating part 422 can still form a receiving space for receiving the ball part 61.

[0087] In one specific implementation, such as Figure 1 , Figure 2 , Figure 4 and 5 As shown, along the third direction z, the end of the first bracket 1 away from the base 8 is also provided with a first opening 12, which is connected to the first through hole 11. The tool detection device also includes a top cover 9, which is connected to the side of the first bracket 1 and the second bracket 2 away from the base 8 to block the first opening 12.

[0088] In this embodiment, the first opening 12 is used to provide a space for the connection between the connector 6 and the first bracket 1, so as to avoid interference between the connector 6 and the first bracket 1, which helps to reduce the assembly difficulty between the connector 6 and the first bracket 1, thereby improving the overall assembly efficiency of the tool detection device.

[0089] Meanwhile, the tool inspection device also includes a first sidewall (not shown in the figure), a second sidewall (not shown in the figure), and a top cover 9. Along the second direction y, the first and second sidewalls are distributed on both sides of each bracket. Along the first direction x, one end of each sidewall is connected to the first bracket 1, and the other end is connected to the second bracket 2. Along the third direction z, one end of each sidewall is connected to the base 8, and the other end is connected to the top cover 9, so that the first sidewall, the second sidewall, the base 8, and the top cover 9 can form a shell for the tool inspection device, preventing external impurities from entering the interior of the tool inspection device, thereby reducing the possibility of contamination or damage to the internal components of the tool inspection device, and improving the stability and reliability of the tool inspection device during operation.

[0090] Specifically, along the third direction z, a sealing part (not shown in the figure) is provided on the side of the top cover 9 facing the first opening 12. After the housing of the tool detection device is assembled, at least part of the sealing part is located inside the first opening 12 and abuts against the side wall of the first opening 12 to seal the first opening 12, thereby reducing the possibility of external impurities entering the tool detection device through the first opening 12 and improving the safety of the tool detection device during operation.

[0091] More specifically, along the third direction z, a sealing surface (not shown in the figure) is provided on the side of the sealing part facing the first through hole 11, and the sealing surface can be either a plane or a curved surface. When the sealing surface is curved, the curvature of the sealing surface can be equal to the curvature of the side wall of the first through hole 11, so that after the sealing part seals the first opening 12, the sealing surface and the side wall of the first through hole 11 can together form the first through hole 11. In the embodiment where the sealing surface is plane, the curved sealing surface can not only increase the displacement range of the probe 4 along the third direction z toward the top cover 9, but also make the displacement of the probe 4 in all directions with the ball part 61 as the fulcrum equal, which is beneficial to improve the aesthetics of the tool detection device while ensuring the protective effect of the shell.

[0092] In one possible implementation, the size of the first opening 12 along the second direction y is larger than the size of the probe 4 along the second direction y, so that the connector 6 is assembled with the probe 4 first, and then assembled with the first bracket 1, which is beneficial to further improve the assembly efficiency of the tool detection device.

[0093] In other embodiments, the first opening 12 may be located in other directions of the first through hole 11 and communicate with the first through hole 11. For example, when the first opening 12 is located on the side of the first through hole 11 facing the base plate 8 along a third direction z, the sealing part may be located on the base 8; or, when the first opening 12 is located on any side of the first through hole 11 along a second direction y, the sealing part may be a separate component and may be detachably connected to the first bracket 1.

[0094] In one specific implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the tool detection device also includes a third bracket 3, which is mounted on the base 8 and located between the first bracket 1 and the second bracket 2. The third bracket 3 has a third through hole 31 extending along the first direction x, and at least a portion of the probe 4 is located within the third through hole 31. The tool detection device also includes an elastic element (not shown in the figure), through which the probe 4 is elastically connected to the third bracket 3.

[0095] In this embodiment of the application, along the first direction x, the detector 4 may include a first end (not shown in the figure) and a second end (not shown in the figure) arranged opposite to each other. The first end of the detector 4 is connected to the first bracket 1 through the connector 6, and the second end of the detector 4 extends toward the direction close to the detection element 5 to shorten the distance between the detector 4 and the detection element 5 so that the detection element 5 can more accurately detect the displacement of the detector 4.

[0096] However, as the second end extends, the probe 4 cannot remain horizontal and gradually shifts towards the base 8 along the third direction z. This causes the axis of the probe 4 in the initial state to not coincide with the axis of the detection element 5 along the first direction x, thus affecting the detection effect of the tool detection device. Therefore, in this embodiment, the above problem can be solved by setting a third support 3 between the first support 1 and the second support 2 to support the second end of the probe 4.

[0097] Specifically, along the first direction x, the first end of the probe 4 is connected to the first bracket 1 via the connector 6, and the second end of the probe 4 is connected to the third bracket 3 via the elastic member, so that both the first bracket 1 and the third bracket 3 are used to support the probe 4, thereby improving the installation stability of the probe 4.

[0098] When the probe 4 is in the initial state, the axis of the probe 4 can be aligned with the axis of the detector 5, so that the displacement of the probe 4 in the initial state is zero. This allows the detector 5 to accurately measure the displacement of the probe 4 after it is displaced, which helps to improve the sensitivity of the detector 5 and further improve the detection accuracy, so as to ensure the accuracy of the detection results of the tool detection device.

[0099] More specifically, along the second direction y and the third direction z, a plurality of elastic elements are provided between the probe 4 and the third support 3, and the plurality of elastic elements are distributed at intervals along the axial direction of the third through hole 31, so that after the probe 4 is displaced in any direction under the drive of the tool to be tested, it can be reset under the action of the elastic elements.

[0100] When the probe 4 is displaced under the drive of the tool to be tested, the probe 4 can rotate along the second direction y, or along the third direction z, or around the first direction x, with the ball portion 61 of the connector 6 as the fulcrum. During the rotation, it compresses the elastic element in the corresponding direction, causing the elastic element to contract under pressure. When the tool to be tested is no longer in contact with the probe 4, the contracted elastic element can release its rebound force to drive the probe 4 to reset, so that the axis of the probe 4 re-aligns with the axis of the detector 5 along the first direction x, ensuring that the tool detection device can proceed to the next step. Therefore, in this embodiment, by setting an elastic element between the probe 4 and the third support 3, it is ensured that the probe 4 automatically resets after each displacement, thereby reducing the need for manual calibration after each displacement, which helps to reduce the number of calibrations and improve detection efficiency. At the same time, the automatic reset of the probe 4 driven by the elastic element can also improve the automation level of the tool detection device, reduce manual intervention, and better meet the actual use requirements.

[0101] In one specific implementation, such as Figure 6 and Figure 7 As shown, the sidewall of the third through hole 31 is provided with a plurality of first mounting grooves 312 spaced apart circumferentially, and the sidewall of the probe 4 is provided with a plurality of second mounting grooves 421a spaced apart circumferentially. Along the second direction y and the third direction z, each first mounting groove 312 is aligned with each second mounting groove 421a, that is, the plurality of first mounting grooves 312 and the plurality of second mounting grooves 421a are provided in a one-to-one correspondence. There are multiple elastic elements, so that one end of each elastic element is located in the first mounting groove 312 and connected to the third bracket 3, so as to improve the stability and reliability of the connection between the elastic element and the third bracket 3, and the other end of each elastic element is located in the second mounting groove 421a and connected to the probe 4, so as to improve the stability and reliability of the connection between the elastic element and the probe 4.

[0102] In this embodiment, the first mounting groove 312 and the second mounting groove 421a provide deformation space for the elastic element, allowing the second end of the probe 4 to move as far as possible along the second direction y and the third direction z toward the sidewall of the third through hole 31, which helps to expand the detection range of the tool detection device. Simultaneously, the first mounting groove 312 and the second mounting groove 421a restrict the deformation of the elastic element, reducing the possibility of displacement or bending during deformation, thereby improving the stability of the elastic element during deformation and ensuring the stability and reliability of the tool detection device during operation.

[0103] In one specific implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the third bracket 3 is provided with a recess 311 on any side along the first direction x. The recess 311 communicates with each of the second mounting slots 421a. The tool detection device also includes a fixing member 7. At least a portion of the fixing member 7 is located in the recess 311 to block each of the second mounting slots 421a.

[0104] In this embodiment of the application, by providing a recess 311 on either side of the third through hole 31 along the first direction x, it is convenient to process the second mounting groove 421a on the side wall of the third through hole 31, which helps to reduce the processing difficulty of the second mounting groove 421a and improve the production efficiency of the third bracket 3.

[0105] Specifically, during the production process of the third bracket 3, a third through hole 31 can be first machined at a preset position of the third bracket 3. Then, a recess 311 can be machined on any side of the third through hole 31 along the first direction x. Then, a plurality of second mounting grooves 421a distributed circumferentially along the bottom wall of the recess 311 can be machined, such that each second mounting groove 421a has a third opening (not shown in the figure) on the side facing the recess 311 and a fourth opening (not shown in the figure) on the side facing the third through hole 31, so that each second mounting groove 421a can communicate with the recess 311 through the third opening and with the third through hole 31 through the fourth opening.

[0106] The third opening facilitates the installation of the elastic element, and the fourth opening facilitates the elastic element to undergo elastic deformation along the radial direction of the third through hole 31.

[0107] In addition, along the first direction x, the recess 311 can be provided on the side of the third through hole 31 facing the first bracket 1, or it can be provided on the side of the third through hole 31 facing the second bracket 2.

[0108] More specifically, the tool detection device also includes a fixing member 7. Along the first direction x, the fixing member 7 can be installed in the recess 311 and abut against the bottom wall of the recess 311, so that the fixing member 7 can block the third opening of each second mounting groove 421a, thereby reducing the possibility of the elastic member disengaging from the second mounting groove 421a along the first direction x, and improving the stability and reliability of the connection between the elastic member and the third bracket 3.

[0109] In one specific implementation, such as Figure 3 As shown, there is a second gap L2 between the third support 3 and the first support 1, and a third gap L3 between the third support 3 and the second support 2. L2 and L3 satisfy 0.2≤L2 / L3≤0.8, where L2 satisfies 10mm≤L2≤20mm and L3 satisfies 25mm≤L3≤35mm.

[0110] In this embodiment, the ratio of the second gap L2 to the third gap L3 can specifically be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, etc. When the ratio of the second gap L2 to the third gap L3 satisfies 0.2≤L2 / L3≤0.8, the distances between the first support 1, the second support 2, and the third support 3 along the first direction x are within a suitable proportional range. This makes the internal structure of the tool detection device more compact, avoiding the possibility of interference with other components on the work platform due to the excessive size of the tool detection device, and facilitating the miniaturization of the tool detection device.

[0111] Specifically, the second gap L2 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc. When the second gap L2 satisfies 10mm≤L2≤20mm, the distance between the third support 3 and the first support 1 is appropriate, allowing the probe 4 to remain horizontal under the support of the first support 1 and the third support 3. This ensures that the axis of the probe 4 in the initial state coincides with the axis of the detection element 5 along the first direction x, thereby improving the detection effect of the tool detection device.

[0112] Meanwhile, the third gap L3 can specifically be 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, etc. When the third gap L3 satisfies 25mm≤L3≤35mm, the distance between the third support 3 and the second support 2 is moderate, ensuring that at least a portion of the probe 4 and at least a portion of the detection element 5 can be located between the second support 2 and the third support 3, further shortening the distance between the detection element 5 and the probe 4, thereby guaranteeing the measurement effect of the detection element 5.

[0113] In one specific implementation, such as Figure 3 As shown, along the first direction x, there is a fourth gap L4 between the probe 4 and the detection 5, and L4 satisfies 1mm≤L4≤1.5mm.

[0114] In this embodiment of the application, the fourth gap L4 can specifically be 1mm, 1.02mm, 1.04mm, 1.06mm, 1.08mm, 1.1mm, 1.12mm, 1.14mm, 1.16mm, 1.18mm, 1.2mm, 1.22mm, 1.24mm, 1.26mm, 1.28mm, 1.3mm, 1.32mm, 1.34mm, 1.36mm, 1.38mm, 1.4mm, 1.42mm, 1.44mm, 1.46mm, 1.48mm, 1.5mm, etc.

[0115] When the fourth gap L4 is too small (e.g., L4 is less than 1 mm), along the first direction x, the probe 4 and the detection element 5 are too close. The fourth gap L4 is likely to be less than or close to the minimum detection range of the detection element 5, causing the detection element 5 to be unable to accurately detect the displacement of the probe 4, thus affecting the detection accuracy of the tool detection device. Simultaneously, when the probe 4 and the detection element 5 are too close, the probe 4 is also prone to contacting the detection element 5 during movement, thus affecting the working performance of the detection element 5.

[0116] When the fourth gap L4 is too large (e.g., L4 is greater than 1.5 mm), the distance between the probe 4 and the detection element 5 along the first direction x is too far, which can easily affect the ability of the detection element 5 to receive or transmit signals, resulting in a decrease in the stability and accuracy of the measurement of the detection element 5, and thus making it impossible to accurately detect the displacement of the probe 4.

[0117] Therefore, when the fourth gap L4 satisfies 1mm≤L4≤1.5mm, along the first direction x, the distance between the probe 4 and the detection element 5 is moderate, the fourth gap L4 can be located within the detection range of the detection element 5, and it will not touch the detection element 5 during the movement of the probe 4, so that the probe 5 can stably receive or transmit signals, thereby accurately measuring the displacement of the probe 4, so as to improve the accuracy and reliability of the detection effect.

[0118] An embodiment of this application also provides a processing device, which includes a work platform, a machining spindle, and a tool detection device. Along a third direction z, the machining spindle is located above the work platform, and a tool to be detected is disposed on the side of the machining spindle facing the work platform. The tool detection device is mounted on the work platform and is used to detect the working state of the tool to be detected. This tool detection device is any of the tool detection devices described above.

[0119] In this embodiment of the application, the top cover 9 of the tool detection device is provided with a positioning ring 91, such as Figure 1 As shown, the positioning ring 91 has a fourth through hole 911, and the center of the fourth through hole 911 coincides with the projection of the axis of the tool detection device along the third direction z, so that the machining spindle can be positioned by the positioning ring 91.

[0120] Since the detector 4 is installed in the first through hole 11 of the first bracket 1 and the detector 5 is installed in the second through hole 21 of the second bracket 2, the detector 4 and the detector 5 are aligned along the center of the first direction x, so that the axis of the detector 4, the axis of the detector 5, and the center of the second through hole 21 can be aligned along the first direction x, thereby forming the axis of the tool detection device extending along the first direction x. When the first gap between the detector 4 and the sidewall of the first through hole 11 is equal everywhere along the second direction y and the third direction z, the axis of the detector 4, the center of the first through hole 11, the axis of the detector 5, and the center of the second through hole 21 can be aligned along the first direction x, thereby also forming the axis of the tool detection device extending along the first direction x. Therefore, in this embodiment, by setting the center of the fourth through hole 911 to coincide with the projection of the tool detection device axis along the third direction z, the positioning of the tool detection device can be achieved, and the positioning accuracy of the tool detection device can be improved.

[0121] The machining equipment also includes a control system, which is electrically or signal-connected to the machining spindle and the tool detection device. The machining spindle is equipped with a probe (not shown in the figure), and the top cover 9 of the tool detection device is equipped with a positioning ring 91, which has a fourth through hole 911. During positioning, the operator can manually control the movement of the machining spindle, thereby moving the probe so that it can extend into the fourth through hole 911 for positioning.

[0122] Specifically, the operator first controls the probe to extend into the fourth through hole 911 along the third direction z, and then controls the probe to move along the first direction x and the second direction y so that the probe can make multiple contacts with the side wall of the fourth through hole 911. The coordinates at each contact are recorded so that the center coordinates of the fourth through hole 911 can be calculated through multiple sets of coordinate data. At the same time, the center coordinates of the fourth through hole 911 are set as the reference coordinates (X0, Y0) and recorded in the control system to realize the positioning of the tool detection device.

[0123] During the inspection of the tool by the tool inspection device, the control system of the machining equipment can control the machining spindle to move towards the probe 4, so as to drive the tool to be inspected to move synchronously. When the tool to be inspected comes into contact with the probe 4, the probe 4 will be displaced with the connecting member 6 as the fulcrum under the drive of the tool to be inspected. The detection member 5 can detect the displacement of the probe 4 in real time and transmit the detection result to the control system in real time, so that the control system can determine whether the displacement of the probe 4 is within the preset range based on the detection result of the detection member 5, thereby determining whether the tool meets the working conditions.

[0124] Specifically, when the control system determines that the displacement of the probe 4 is within the preset range, the tool meets the working conditions, and the control system can control the machining spindle to move the tool to the machining area so that the workpiece to be machined can be machined by the tool; when the control system determines that the displacement of the probe 4 is not within the preset range, the tool does not meet the working conditions, and the control system can control the machining spindle to move the tool to the maintenance area so that the staff can repair or replace the tool.

[0125] In one specific implementation, the tool detection device is capable of detecting the diameter of the tool to be detected.

[0126] Before inspecting the cutting tool, the control system first controls the machining spindle to move the cutting tool to either side of the probe 4 along the second direction y, and ensures that the cutting tool can contact the probe part 41 during the subsequent movement of the machining spindle towards the probe 4 along the second direction y. It should be noted that the above steps can be performed by a preset program or manually.

[0127] First, the control system controls the machining spindle to move from one side of the tool detection device along the second direction y towards the probe 4. When the tool to be detected touches the probe 41, the control system controls the machining spindle to stop moving. At this time, the probe 4 is displaced under the drive of the tool to be detected. The detection unit 5 can transmit the detected displacement result to the control system in real time and record the first coordinate (X1, Y1). After recording, the control system controls the machining spindle to move along the second direction y towards the direction away from the probe 4.

[0128] Then, the control system controls the machining spindle to move from the other side of the tool detection device along the second direction y towards the probe 4. When the tool to be detected touches the probe 41, the control system controls the machining spindle to stop moving. At this time, the probe 4 is displaced under the drive of the tool to be detected. The detection unit 5 can transmit the detected displacement result to the control system in real time and record the second coordinate (X2, Y2). After recording, the control system controls the machining spindle to move along the second direction y towards the direction away from the probe 4.

[0129] After the measurement is completed, the control system can calculate the diameter D1 of the tool to be tested using a preset diameter formula and compare it with the preset tool diameter D0. The preset diameter formula is D1 = Y1 - Y2 - D2, where D2 is the radial dimension of the detection unit 41.

[0130] When D0-D1 satisfies 0.015mm≤D0-D1, the tool meets the working conditions, and the control system can control the machining spindle to move the tool to the machining area so that the workpiece to be machined can be machined by the tool.

[0131] When D0-D1 satisfies -0.016mm≤D0-D1≤-0.035mm, the tool does not meet the working conditions and the tool wear is low. The control system can control the machining spindle to move the tool to the maintenance area so that the staff can repair the tool.

[0132] When D0-D1 meets the condition of 0.36mm≤D0-D1, the tool does not meet the working conditions and the tool wear is high. The control system can control the machining spindle to move the tool to the maintenance area so that the operator can replace the tool and remeasure the new tool after the replacement is completed.

[0133] In one specific implementation, the tool inspection device is capable of detecting the length difference of the tool to be inspected before and after processing.

[0134] Before inspecting the cutting tool, the control system first controls the machining spindle to move the cutting tool to be inspected above the probe 4 along the third direction z, and ensures that the cutting tool can contact the probe part 41 during the subsequent movement of the machining spindle towards the probe 4 along the third direction z. It should be noted that the above steps can be performed by a preset program or manually.

[0135] First, the control system controls the machining spindle to move from above the tool detection device along the third direction (z) towards the probe 4. When the tool to be detected contacts the probe 41, the control system controls the machining spindle to stop moving. At this time, the probe 4 is displaced under the drive of the tool to be detected. The detection unit 5 can transmit the detected displacement result to the control system in real time and record the third coordinate (X3, Z1). After recording, the control system controls the machining spindle to move along the third direction (z) away from the probe 4 to move the tool to the machining area so that the workpiece to be machined can be machined using the tool.

[0136] After the tool has worked a preset number of times, the control system controls the machining spindle to move the tool away from the machining area and bring it back above the tool detection device so that the depth of the tool can be measured again.

[0137] Then, the control system controls the machining spindle to move from above the tool detection device along the third direction toward the probe 4. When the tool to be detected touches the probe 41, the control system controls the machining spindle to stop moving. At this time, the probe 4 is displaced under the drive of the tool to be detected. The detection unit 5 can transmit the detected displacement result to the control system in real time and record the fourth coordinate (X4, Z2). After recording, the control system controls the machining spindle to move along the third direction z toward the direction away from the probe 4.

[0138] After the measurement is completed, the control system can calculate the length difference H1 of the tool to be tested using a preset length difference formula. The preset length difference formula is H1 = Z1 - Z2.

[0139] When H1 satisfies -0.005mm≤H1≤-0.015mm, the tool meets the working conditions, and the control system can control the machining spindle to move the tool to the machining area so that the workpiece to be machined can be machined by the tool.

[0140] When H1 satisfies -0.016mm≤H1≤-0.035mm, the tool does not meet the working conditions and the tool wear is low. The control system can control the machining spindle to move the tool to the maintenance area so that the staff can repair the tool.

[0141] When H1 satisfies 0.36mm≤H1, the tool does not meet the working conditions and the tool wear is high. The control system can control the machining spindle to move the tool to the maintenance area so that the staff can replace the tool and remeasure the new tool after replacement.

[0142] In one specific implementation, the tool detection device is capable of detecting chipping on the tool to be tested.

[0143] Before inspecting the cutting tool, the control system first controls the machining spindle to move the cutting tool to either side of the probe 4 along the second direction y, and ensures that the cutting tool can contact the probe 41 during the subsequent movement of the machining spindle towards the probe 4 along the second direction y. It should be noted that the above steps can be performed by a preset program or manually. The following explanation uses a cutting tool with four cutting edges as an example.

[0144] First, the control system controls the machining spindle to move from either side of the tool detection device along the second direction y towards the detector 4. When the first cutting edge of the tool to be detected contacts the detector 41, the control system controls the machining spindle to stop moving. At this time, the detector 4 is displaced under the drive of the first cutting edge. The detector 5 can transmit the detected displacement result to the control system in real time and record the fifth coordinate (X5, Y5). After recording, the control system controls the machining spindle to move along the second direction y towards the direction away from the detector 4.

[0145] Then, the control system controls the machining spindle to rotate the tool to be tested by a first preset angle, and then moves again from the same side of the tool detection device along the second direction y towards the detector 4. When the second cutting edge of the tool to be tested contacts the detector 41, the control system controls the machining spindle to stop moving. At this time, the detector 4 is displaced under the drive of the second cutting edge. The detector 5 can transmit the detected displacement result to the control system in real time and record the sixth coordinate (X6, Y6). After recording, the control system controls the machining spindle to move along the second direction y towards the direction away from the detector 4. The first preset angle is 90°.

[0146] Complete the detection of the third and fourth cutting edges of the tool to be tested by following the above steps, and record the coordinates of the third cutting edge as the seventh coordinate (X7, Y7) and the coordinates of the fourth cutting edge as the eighth coordinate (X8, Y8).

[0147] After measurement, the control system can determine the chipping condition of the tool under test based on preset chipping conditions. Specifically, when Y5 is at its maximum value and Y8 is at its minimum value, the preset chipping condition is 0.05mm < Y5 - Y8. If Y5 - Y8 satisfies 0.05mm < Y5 - Y8, the tool does not meet the working conditions, and the chipping condition is severe. The control system can then control the machining spindle to move the tool to the maintenance area so that the operator can replace it. After replacement, the new tool under test will be measured again.

[0148] It should be noted that when the number of blades of the tool to be tested is two, the first preset angle is 180°; when the number of blades of the tool to be tested is three, the first preset angle is 120°, and so on. The first preset angle is obtained by dividing 360° by the number of blades of the tool to be tested, thereby ensuring that each blade on the tool to be tested can come into contact with the detection unit 41.

[0149] In one specific implementation, the tool detection device is capable of detecting the runout of the tool to be tested.

[0150] Before inspecting the cutting tool, the control system first controls the machining spindle to move the cutting tool to either side of the probe 4 along the second direction y, and ensures that the cutting tool can contact the probe part 41 during the subsequent movement of the machining spindle towards the probe 4 along the second direction y. It should be noted that the above steps can be performed by a preset program or manually.

[0151] First, the control system controls the machining spindle to move from either side of the tool detection device along the second direction y towards the probe 4. When the tool to be detected contacts the probe 41, the control system controls the machining spindle to stop moving. At this time, the probe 4 is displaced under the drive of the tool to be detected. The detection unit 5 can transmit the detected displacement result to the control system in real time and record the ninth coordinate (X9, Y9). After recording, the control system controls the machining spindle to move along the second direction y towards the direction away from the probe 4.

[0152] Then, the control system controls the machining spindle to rotate the tool under test by a second preset angle, and then moves again from the same side of the tool detection device along the second direction y towards the probe 4. When the tool under test contacts the probe 41, the control system controls the machining spindle to stop moving. At this time, the probe 4 is displaced under the drive of the tool under test. The detection component 5 can transmit the detected displacement result to the control system in real time and record the tenth coordinate (X10, Y10). After recording, the control system controls the machining spindle to move along the second direction y towards the direction away from the probe 4. The second preset angle is 15°.

[0153] Repeat the above steps until the machining spindle has rotated a total of 360° (i.e., 24 measurements) and then stop to complete the inspection of the tool to be inspected, and record the coordinates of each measurement in sequence.

[0154] Specifically, the eleventh coordinate is (X11, Y11), the twelfth coordinate is (X12, Y12), the thirteenth coordinate is (X13, Y13), the fourteenth coordinate is (X14, Y14), the fifteenth coordinate is (X15, Y15), the sixteenth coordinate is (X16, Y16), the seventeenth coordinate is (X17, Y17), the eighteenth coordinate is (X18, Y18), the nineteenth coordinate is (X19, Y19), the twentieth coordinate is (X20, Y20), the twenty-first coordinate is (X21, Y21), the twenty-second coordinate is (X22, Y22), the twenty-third coordinate is (X23, Y23), and the twenty-fourth coordinate is (X24, Y24).

[0155] After measurement, the control system can determine the runout of the tool under test based on preset runout conditions. Specifically, when Y9 is at its maximum value and Y24 is at its minimum value, the preset runout condition is 0.015mm < Y9 - Y24. Furthermore, if Y9 - Y24 satisfies 0.015mm < Y9 - Y24, the tool does not meet the working conditions, and the tool runout is severe. The control system can then control the machining spindle to move the tool to the maintenance area so that the operator can adjust the tool and perform a new measurement after adjustment.
