[0026] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-7 As shown, this embodiment discloses a laser precision machining head for diamond tools, including a housing 1. From top to bottom, an isolator 2, a dichroic mirror 3, a plano-concave mirror 4, and a focusing objective lens 5 are arranged on the housing 1. The top of the isolator 2 extends through to the top of the housing 1 and corresponds to the laser source. The dichroic mirror 3 is connected to the inner wall of the housing 1 through a connecting component 6. The plano-concave mirror 4 is arranged with its flat surface facing upward and is connected to a micro-moving platform 8 through a connecting component 7. The micro-moving platform 8 is connected to the inner wall of the housing 1. The bottom of the focusing objective lens 5 extends movably through to the bottom of the housing 1, and the top is connected to an objective lens adjustment component 9, which is connected to the housing 1.

[0028] In this embodiment, the laser source is set to a 1064nm infrared nanosecond laser, the dichroic mirror 3 can completely transmit the 1064nm infrared nanosecond laser, and the micro moving platform 8 is set to a high-precision piezoelectric ceramic displacement platform. Through changes in external input voltage, the plano-concave mirror 4 can be driven to move rapidly and precisely up and down through the connecting component 2 7.

[0029] The working principle of the above technical solution is as follows: the laser beam first enters the interior of the housing 1 through the isolator 2, then enters the focusing objective lens 5 through the dichroic mirror 3 and the plano-concave mirror 4 in sequence, and finally forms a light spot through the focusing objective lens 5.

[0030] This design utilizes a miniature moving platform 8 to move the plano-concave mirror 4 up and down, forming a beam adjustment system with the focusing objective lens 5. This system allows for rapid and precise adjustment of the laser beam's focal position and spot size, flexibly addressing the machining needs of diamond-coated tools with varying thicknesses and complex curved surfaces. While ensuring machining accuracy, it improves machining efficiency, reduces thermal damage, and optimizes laser energy distribution under different materials and machining tasks. Through this structural design, this invention enables more efficient, precise, and controllable diamond-coated tool machining, effectively improving the performance and machining quality of diamond-coated tools.

[0031] In a further optimized design, the dichroic mirror 3 is arranged at an angle, with a beam splitter 10, a focusing lens 11, and a collecting head 12 arranged sequentially on its reflected light path. The beam splitter 10 is connected to the inner wall of the housing 1 via a connecting component 3 13, the focusing lens 11 is connected to the inner wall of the housing 1 via a connecting component 4 14, and the collecting head 12 is connected to the outer wall of the spectrometer 15 via a fixing bracket 17. The spectrometer 15 is connected to the inner wall of the housing 1, and the collecting head 12 is connected to the spectrometer 15.

[0032] In this embodiment, the light beam reflected from the tool processing area is reflected to the beam splitter 10 by the dichroic mirror 3. The visible light beam transmitted through the beam splitter 10 enters the focusing lens 11, is collected by the collecting head 12, and is transmitted to the spectrometer 15 for analysis.

[0033] By adopting this scheme and setting up the above structure, various spectral signals reflected from the processing area can be acquired and analyzed in real time, thereby reflecting the processing status of diamond-coated tools in real time, so as to accurately control the processing process.

[0034] The scheme is further optimized by arranging the beam splitter 10 at an angle, and setting a CCD camera 16 on its reflected light path. The CCD camera 16 is fixedly connected to the housing 1.

[0035] In this embodiment, a portion of the light beam reflected by the dichroic mirror 3 to the beam splitter 10 passes through the beam splitter 10, while another portion is reflected by the tilted beam splitter 10 to the CCD camera 16. The CCD camera 16 can acquire images of the reflected visible light beam in real time. The images acquired by the CCD camera 16 are transmitted to the subsequent analysis system in the form of signals, enabling real-time monitoring of tool morphology changes and machining quality during the machining process.

[0036] Further optimization of the scheme: the objective lens adjustment assembly 9 includes an objective lens fixing plate 91 connected to the top of the focusing objective lens 5. The objective lens fixing plate 91 is connected to the actuating end of the linear module 93 through the objective lens fixing suspension plate 92. The linear module 93 is connected to the housing 1 through the fixing seat 94.

[0037] In this embodiment, the top of the focusing objective lens 5 is connected to the objective lens fixing plate 91 by a threaded connection, the objective lens fixing plate 91 is fixedly connected to the objective lens fixing suspension plate 92, and the objective lens fixing suspension plate 92 is connected to the actuating end of the linear module 93.

[0038] The housing 1 includes a box 101 with an opening on one side and a side plate 102 provided at the opening. The side plate 102 is connected to the box 101 by bolts. The fixing seat 94 is fixed on the outer side wall of the side plate 102. The linear module 93 is fixedly installed on the fixing seat 94. One end of the objective lens fixing plate 92 passes through the clearance opening provided on the side plate 102 to the outside and is fixedly connected to the moving end of the linear module 93. The clearance opening can meet the needs of the objective lens fixing plate 92 to move up and down.

[0039] Using this scheme, the linear module 93, along with the objective lens fixing plate 92, the objective lens fixing plate 91, and the focusing objective lens 5, can be moved up and down as a whole to adjust the focal position of the laser beam. Moreover, the linear module 93 has a larger adjustment range than the micro moving platform 8, thus making this invention suitable for processing large and irregularly shaped tools.

[0040] The scheme is further optimized. The connecting component 6 includes a frame 61 that is fixedly connected to the dichroic mirror 3. The frame 61 is connected to the inner wall of the housing 1 through a pad 62.

[0041] In this embodiment, the eyeglass frame 61 is fixedly connected to the pad 62 by screws, and the pad 62 is fixedly connected to the inner wall of the side plate 102 by screws.

[0042] The scheme is further optimized. The connecting component 2 7 includes a mirror frame 2 71 that is fixedly connected to the plano-concave mirror 4. The mirror frame 2 71 is connected to the micro mobile platform 8 through a pad 2 72.

[0043] In this embodiment, the second frame 71 is fixedly connected to the second pad 72 by screws, the second pad 72 is fixedly connected to the micro mobile platform 8 by screws, and the micro mobile platform 8 is fixedly connected to the inner wall of the side plate 102 by screws.

[0044] Further optimization of the scheme: the connecting component 3 13 includes a lens frame 3 131 fixedly connected to the beam splitter 10, and the lens frame 3 131 is connected to the inner wall of the housing 1 through a pad 3 132.

[0045] In this embodiment, the frame 3 131 is fixedly connected to the pad 3 132 by screws, and the pad 3 132 is fixedly connected to the inner wall of the side plate 102 by screws.

[0046] In a further optimized design, the connecting component 4 14 includes a frame 4 141 fixedly connected to the focusing lens 11, and the frame 4 141 is connected to the inner wall of the housing 1 via a pad 4 142.

[0047] In this embodiment, the frame 4 141 is fixedly connected to the pad 4 142 by screws, and the pad 4 142 is fixedly connected to the inner wall of the side plate 102 by screws.

[0048] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
