[0034] In an embodiment of the utility model, as shown in Figures 1-4 The cutter pre-adjusting mechanism for machining center comprises a cutter 1, a cutter holder 2, an axial detector 3, a radial detector 4 and a lifting source 5. The cutter holder 2 is installed on the top of the cutter 1, and is used for mounting and positioning the cutter 1. The axial detector 3 is arranged on the center line of the cutting edge of the cutter 1, and the detection head of the axial detector 3 irradiates along the cutting edge of the cutter 1. The axial detector 3 is used for measuring the length of the cutter 1. The radial detector 4 is positioned on the side of the cutter 1, and the detection head of the radial detector 4 moves and measures the irradiation along the radial direction of the cutter 1. The radial detector 4 is used for measuring the diameter of the cutter 1. The lifting source 5 is positioned on the side of the cutter holder 2, and the lifting end of the lifting source 5 is fixedly connected with the cutter holder 2. The axial detector 3 is electrically connected with the lifting source 5. The lifting source 5 can pre-adjust the axial length of the cutter 1 through the axial detector 3.

[0035] The cutter pre-adjusting mechanism for machining center provided by the utility model realizes the rapid pre-adjustment and accurate measurement of the cutter 1 through the accurate measurement of the axial detector 3 and the radial detector 4 and the automatic adjustment function of the lifting source 5, improves the machining precision and efficiency, and reduces the complexity and error of manual operation. Specifically as follows:

[0036] (1) The axial detector 3 is arranged on the center line of the cutting edge of the cutter 1, and the detection head of the axial detector 3 irradiates along the cutting edge of the cutter 1, which is used for measuring the length of the cutter 1. This design enables the axial detector 3 to accurately measure the length of the cutter 1, thereby ensuring the accuracy of the cutting depth of the cutter 1 in the machining process. At the same time, the axial detector 3 can monitor the wear of the cutter 1 in real time during the machining process, timely find the change of the length of the cutter 1, and adjust the machining parameters accordingly, thereby effectively reducing the machining error caused by the length error of the cutter 1 and improving the machining precision.

[0037] (2) The radial detector 4 can accurately measure the diameter of the cutter 1, thereby ensuring the accuracy of the cutting size of the cutter 1 in the machining process. In addition, the radial detector 4 can also detect the wear and damage of the cutter 1, and timely find the change of the radial size of the cutter 1. The measurement data of the radial detector 4 provides a reference for the operator, so that the operator can timely adjust the cutter 1 or replace the cutter 1, thereby optimizing the machining process parameters, and improving the machining efficiency and quality.

[0038] (3) The lifting source 5 can automatically adjust the axial position of the tool 1 through the measurement data of the axial detector 3, thereby ensuring that the extension length of the tool 1 meets the processing requirements. This automatic adjustment function not only reduces the time and error of manual adjustment, but also improves the efficiency of tool 1 pre-adjustment.

[0039] Preferably, the axial detector 3 includes a first moving source 31 and a first laser displacement sensor 32. The first moving source 31 is arranged in the axial direction of the tool 1, and the first laser displacement sensor 32 is positioned at the sliding end of the first moving source 31 and irradiates along the tool tip of the tool 1. The first moving source 31 can move along the axial direction of the tool 1, driving the first laser displacement sensor 32 to different measurement positions, thereby realizing accurate measurement of the extension length of the tool 1.

[0040] Preferably, the first laser displacement sensor 32 adopts high-precision laser triangulation method, which can accurately measure the axial displacement of the tool 1. This sensor calculates the distance between the tool tip of the tool 1 and the sensor by emitting a laser beam and receiving a reflected signal using the principle of triangulation. Its measurement accuracy can reach micrometer level, with fast response speed, suitable for dynamic measurement scenarios. During the tool 1 pre-adjustment process, the first laser displacement sensor 32 can provide real-time feedback on the extension length of the tool 1, ensuring the accuracy of the cutting depth of the tool 1 during the machining process. Through this high-precision measurement, the efficiency and accuracy of tool 1 pre-adjustment can be improved, and the processing error caused by the length error of the tool 1 can be reduced.

[0041] Preferably, the radial detector 4 includes a second moving source 41 and a second laser displacement sensor 42. The second moving source 41 is arranged in the radial direction of the tool 1, and the second laser displacement sensor 42 is positioned at the sliding end of the second moving source 41 and irradiates along the radial direction of the tool 1. The second laser displacement sensor 42 adopts high-precision laser triangulation method, which can accurately measure the radial size of the tool 1. This sensor calculates the distance between the surface of the tool 1 and the sensor by emitting a laser beam and receiving a reflected signal using the principle of triangulation, with measurement accuracy up to micrometer level. During the tool 1 pre-adjustment process, the second laser displacement sensor 42 can provide real-time feedback on the radial size of the tool 1, ensuring the accuracy of the cutting size of the tool 1 during the machining process. Through this high-precision measurement, the efficiency and accuracy of tool 1 pre-adjustment can be significantly improved, and the processing error caused by the diameter error of the tool 1 can be reduced.

[0042] The tool pre-adjusting mechanism for the machining center further comprises a turnover mechanism 6 arranged between the axial detector 3 and the radial detector 4. The main function of the turnover mechanism 6 is protection. It can effectively block the debris generated in the machining process from entering the inside of the axial detector 3 and the radial detector 4, thereby preventing these precision components from being damaged due to debris accumulation or collision. The turnover mechanism 6 not only enhances the durability of the tool 1 pre-adjusting mechanism, but also ensures the accuracy of the detection results, thereby improving the efficiency of the tool 1 pre-adjusting and ensuring the stable operation of the subsequent machining process.

[0043] Specifically, the turnover mechanism 6 comprises a middle connecting plate 61, a bottom connecting plate 62, a top connecting plate 63, a top plate 64, and a rotation source 65. The middle connecting plate 61 is arranged between the bottom connecting plate 62 and the top connecting plate 63. The top plate 64 is arranged on the top of the top connecting plate 63. The rotation source 65 is connected between the top plate 64 and the top connecting plate 63. The axial detector 3 is arranged on the bottom connecting plate 62. The radial detector 4 is arranged on the middle connecting plate 61.

[0044] The turnover mechanism 6 of the embodiment drives the top plate 64 and the connecting plate to rotate through the rotation source 65, realizes the turnover action of the axial detector 3 and the radial detector 4, thereby hiding the detectors in the protection state, preventing debris from entering and protecting the detectors, ensuring detection accuracy and equipment durability, and thereby improving the efficiency of the tool 1 pre-adjusting.

[0045] Specifically, the top connecting plate 63 comprises an upper plate a and a lower plate b. The upper plate a and the lower plate b are connected by a third movement source. The upper plate a is connected with the top plate 64, and the lower plate b is connected with the middle connecting plate 61. The third movement source pushes the upper plate a and the lower plate b to move relative to each other through its power output end, thereby realizing the telescopic movement of the top connecting plate 63 in the vertical direction. This process enables the turnover mechanism 6 to adjust its overall height when needed to adapt to different sizes of tools 1 or machining requirements, while providing more flexible space adjustment for the axial detector 3 and the radial detector 4, ensuring that the detectors can accurately and efficiently measure in different working conditions, thereby further improving the efficiency of the tool 1 pre-adjusting.

[0046] The tool pre-adjusting mechanism for the machining center further comprises a rotation mechanism 7 for rotating the tool 1 to a specified angle to measure and adjust each side of the tool 1. The rotation mechanism 7 is arranged on the lifting source 5. Through the cooperation with the lifting source 5, the rotation mechanism 7 realizes the rotation operation of the tool 1 at different height positions, further improving the flexibility and accuracy of the tool 1 pre-adjusting.

[0047] Specifically, the rotating mechanism 7 includes an image collector 71, a rotating driving source 72 and a rotating connecting plate 73. The image collector 71 is arranged at the bottom of the tool 1, and is used for irradiating the tool 1 to position the tool 1, and ensuring accurate positioning of the tool 1 during rotation. The rotating connecting plate 73 is connected to one end of the lifting source 5, and the rotating driving source 72 is arranged at the other end of the rotating connecting plate 73. The rotating driving source 72 accurately rotates the tool 1 to a specified angle through the feedback signal of the image collector 71. Then, the image collector 71 transmits the collected tool 1 position information to the control system, and the control system adjusts the motion parameters of the rotating driving source 72 according to the information, so as to realize high-precision angle adjustment of the tool 1, and ensure cutting accuracy of the tool 1 during machining.

[0048] Preferably, the image collector 71 can adopt a high-resolution camera to provide clearer tool 1 position images, so as to improve the positioning and rotating accuracy. Then, the high-precision image data is transmitted to the control system, and the control system processes the data through a complex algorithm, further optimizes the action of the rotating driving source 72, and ensures that the tool 1 can be accurately rotated to the required angle, so as to improve the pre-adjustment efficiency of the tool 1 in the angle.

[0049] Specifically, the bottom of the tool tip is provided with a positioning member, which is convenient for the image collector 71 to recognize. Preferably, the positioning member can adopt a high-contrast marker, for example, a layer of high-contrast paper or coating is attached to the bottom of the tool tip, such as a black film on a white paper. In this way, the recognition accuracy of the image collector 71 to the tool tip position can be improved, and the image collector 71 can quickly and accurately position the tool tip in a complex machining environment, so as to realize high-precision pre-adjustment and rotation of the tool 1.

[0050] Preferably, the bottom of the rotating driving source 72 is provided with a positioning plate 8, which is used for connecting the equipment. Through the stable connection of the positioning plate 8, the rotating driving source 72 can accurately pre-adjust the tool 1 to a specified position, and provide a reliable positioning basis for subsequent measurement and machining operations.
