DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-5 A polishing device for aspheric optical components includes a base 1, a side plate 2 is arranged on the top of the base 1, a displacement mechanism 3 is arranged on the right side of the side plate 2, an angle adjustment mechanism 4 is arranged on the bottom of the displacement mechanism 3, a fixture 5 is arranged on the left side of the angle adjustment mechanism 4, and a polishing liquid spraying member 6 is arranged on the top of the fixture 5.

[0035] Embodiment 1:

[0036] like Figure 2 As shown, the displacement mechanism 3 includes a mounting box 301, a motor 302, a threaded rod 303, a fixed rod 304, a slide 305 and an opening 306. Through the operation of the motor 302, the slide 305 can be moved horizontally in the opening, thereby driving the angle adjustment mechanism 4 and the clamp 5 to move horizontally, adjusting the distance between the device and the electric polishing disk 7 to facilitate the polishing operation.

[0037] like Figure 3 and Figure 4As shown, the angle adjustment mechanism 4 includes a shell 401, an electric telescopic rod 402 is fixedly mounted on the inner top wall of the shell 401, a rack 403 is fixedly mounted on the driving end of the electric telescopic rod 402, a gear 404 is meshed with the left side of the rack 403, a support rod 405 rotatably connected between the front and rear inner walls of the shell 401 is fixedly mounted inside the gear 404, and a connecting rod 406 connected to the clamp 5 is fixedly mounted on the outer surface of the support rod 405.

[0038] By utilizing the extension and retraction of the electric telescopic rod 402 and the meshing between the rack 403 and the gear 404, the support rod 405 can be driven to rotate left and right. Since the clamp 5 is fixedly mounted on the connecting rod 406, the rotation of the connecting rod 406 can drive the clamp 5 to rotate up and down to adjust the angle of the clamp 5 and adjust the device to the required polishing angle.

[0039] A guide block 407 is provided on the right side of the rack 403, and a guide groove 408 adapted to the guide block 407 is opened on the right inner wall of the shell 401, and a spring 409 is provided between the rack 403 and the inner bottom wall of the shell 401. The rack 403 can slide up and down stably in the guide groove 408 through the guide block 407, and the expansion and contraction of the spring 409 further improves the stability of the rack 403 when moving.

[0040] like Figure 1 and Figure 5 As shown, the polishing liquid spraying part 6 includes a U-shaped rod 601, a focusing tube 602, a bellows 603, a nozzle 604 and a limiting ring 605. Since the U-shaped rod 601 is fixedly installed between the clamp 5 and the focusing tube 602, when the angle of the clamp 5 changes, the angle of the focusing tube 602 is changed accordingly, ensuring that the nozzle 604 can be accurately aligned with the polishing position to improve the flushing effect.

[0041] like Figure 1 As shown, the collection assembly 8 includes a slot 801 , a filter screen 802 , a liquid collection box 803 , a groove 804 and a debris collection box 805 .

[0042] Under the action of the filter 802, and the installation position of the filter 802 is set to an inclined surface, the coolant that is flushed and falls enters the liquid collection box 803 under its own gravity, and the debris can enter the debris collection box 805 along the inclined surface, so that it can be classified and collected for subsequent processing.

[0043] Embodiment 2:

[0044] A polishing process for an aspherical optical component, comprising the following polishing processes:

[0045] 1) First, fix the aspheric optical device by the fixture 5, start the displacement mechanism 3 to adjust the distance between the device and the electric polishing plate 7, drive the threaded rod 303 to rotate by the motor 302, drive the slide 305 to move left, and the slide 305 drives the angle adjustment mechanism 4 to move left, so as to adjust the optical device on the fixture 5 to a suitable position;

[0046] 2) When polishing at other angles is required, the rack 403 is first moved up and down by the extension and retraction of the electric telescopic rod 402, and the rack 403 drives the gear 404 meshing therewith to rotate forward and reversely, and the gear 404 drives the support rod 405 to rotate forward and reversely, and the support rod 405 drives the connecting rod 406 to rotate forward and reversely, so that the angle of the clamp 5 can swing up and down, and the device is polished at different angles by the electric polishing disc 7;

[0047] 3) During the polishing operation, ensure that the bellows 603 is connected to the storage source of the external polishing liquid, and the polishing liquid is introduced into the central tube 602 through the bellows 603 and sprayed out through the nozzle 604. When the angle of the fixture 5 is changed by the angle adjustment mechanism 4, the up and down swing of the fixture 5 drives the U-shaped rod 601 to swing up and down, and the U-shaped rod 601 drives the central tube 602 to swing up and down, so that the nozzle 604 and the device swing synchronously, ensuring that the nozzle 604 can be accurately aligned with the polishing position;

[0048] 4) When the polishing liquid washes down the debris, it is filtered by the filter 802 and flows into the liquid collection box 803, while the debris intercepted on the filter 802 falls along the slope into the debris collection box 805, and the polishing liquid and debris are classified and collected.

[0049] In summary, the aspheric optical component polishing device and its polishing process, through the design of the angle adjustment mechanism 4, enable the fixture 5 to flexibly adjust the angle, thereby realizing multi-angle polishing of the aspheric optical component. This design greatly improves the diversity and flexibility of the polishing process, can meet the polishing requirements of various different angles, and improves the polishing efficiency and polishing quality.

[0050] Furthermore, the polishing liquid spraying member 6 is connected to the fixture 5 via the U-shaped rod 601, ensuring that when the angle of the fixture 5 changes, the spray head 604 can swing accordingly, maintaining accurate spraying on the polishing area and improving the utilization rate of the polishing liquid.

[0051] Furthermore, the collection component 8 realizes the classified collection of the debris and polishing liquid generated during the polishing process through the design of the filter 802 and the debris collection box 805, which not only simplifies the subsequent processing work, but also contributes to the recycling of resources and environmental protection.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
