[0013] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0014] According to an embodiment of the present invention, a grinding wheel feed device for a lens grinding machine is provided.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-9 As shown, the grinding wheel feeding device of the lens grinding machine according to an embodiment of the present invention includes a worktable 1, a work chamber 2 is provided on one side of the top of the worktable 1, a base 3 and a stand 4 are provided on the other side of the top of the worktable 1, a moving clamping mechanism 5 is provided between the work chamber 2 and the base 3; an angle flipping mechanism 6 is provided at the top of the base 3, a grinding wheel driving mechanism 7 is provided at the top of the angle flipping mechanism 6, and a pushing and positioning mechanism 8 is provided at the top of the stand 4.

[0016] By employing the aforementioned technical solution, and by setting up the pushing and positioning mechanism 8 and the angle flipping mechanism 6, the angle of the grinding wheel drive mechanism 7 can be manually adjusted, thereby changing the angle and position of the grinding wheel before, during, or after grinding. Furthermore, with the aid of calibrated scale lines, high-precision feed and adjustment of the grinding wheel can be achieved, meeting the needs of different grinding processing scenarios. By setting up the moving clamping mechanism 5 and the working chamber 2, microscope lenses of different thicknesses and sizes can be clamped, ensuring the stability of the lenses during the grinding process. Simultaneously, the protective function of the working chamber 2 prevents the spillage of lens material dust and contamination from external impurities, maximizing the safety of microscope lens processing and improving lens processing quality.

[0017] In one embodiment, the movable clamping mechanism 5 includes a hydraulic cylinder support 501 disposed at the top of the worktable 1. A push cylinder 502 is disposed at the top of the hydraulic cylinder support 501. A push shaft 503 is disposed at the output end of the push cylinder 502. The push shaft 503 extends into the interior of the work chamber 2, and a movable clamp 504 is disposed at one end of the push shaft 503. Thus, the movable clamp 504 can be pushed close to the fixed clamp 14 by the action of the push cylinder 502 to clamp and fix the microscope lens, ensuring stability during the grinding process.

[0018] In one embodiment, the angle flipping mechanism 6 includes a fixed base plate 601 disposed at the top of the base 3. Fixed tripods 602 are disposed on both sides of the top of the fixed base plate 601. A fixed shaft 603 is disposed between the two fixed tripods 602. Multiple flipping tripods 604 are sleeved on the outer circumference of the fixed shaft 603. A flipping top plate 605 is disposed at the top of the flipping tripods 604. A push plate 606 is disposed in the middle of the side of the flipping top plate 605 near the stand 4. A movable rod frame 607 is disposed on one side of the push plate 606. A movable lifting ring 608 is disposed at the bottom of the push plate 606. Thus, the fixed base plate 601 and the flipping top plate 605 are connected by the action of the fixed shaft 603, so that the flipping top plate 605 moves and drives the grinding wheel drive mechanism 7 at the top to rotate, thereby realizing the feeding of the grinding wheel.

[0019] In one embodiment, the grinding wheel drive mechanism 7 includes a drive motor 701 disposed at the top of the flip-top plate 605. The output end of the drive motor 701 is provided with a coupling 702, and the output end of the coupling 702 is provided with a rotating shaft 703. The rotating shaft 703 extends into the interior of the working chamber 2, and a grinding wheel 704 is disposed at one end of the rotating shaft 703. Thus, the drive motor 701 and the coupling 702 drive the grinding wheel 704 to rotate, thereby grinding the edge of the microscope lens.

[0020] In one embodiment, the aforementioned pushing and positioning mechanism 8 includes an internally threaded box 801 disposed at the top of the base 4. A threaded push rod 802 is disposed through the internally threaded box 801. A knob 803 is disposed at the end of the threaded push rod 802 away from the base 3, and a pushing end 804 is disposed at the end of the threaded push rod 802 near the base 3. An annular groove 805 is formed in the middle of the threaded push rod 802. A bearing 806 is sleeved on the outer circumference of the annular groove 805. An indicator arrow 807 is disposed at the top of the bearing 806. A through groove 808 is formed at the top of the internally threaded box 801, which cooperates with the indicator arrow 807. A bar scale 809 is disposed on both sides of the through groove 808. Thus, the pushing end 804 can be driven to slide laterally by the action of the threaded push rod 802 and the internally threaded box 801, and rotate and adjust by abutting the pushing plate 606 on one side of the flipping top plate 605.

[0021] In one embodiment, for the aforementioned stand 4, a side base plate 9 is provided on one side of the top of the stand 4, and a fixed support rod 10 is provided on the side of the side base plate 9 near the base 3. An L-shaped support rod 11 is provided between the fixed support rod 10 and the movable support rod 607. A fixed lifting ring 12 is provided at the bottom of the side of the stand 4 near the base 3, and a tension spring 13 is provided between the fixed lifting ring 12 and the movable lifting ring 608. Thus, by means of the tension spring 13, the flipping top plate 605 is always pulled towards the stand 4, so that the pushing end 804 and the pushing plate 606 are kept in close contact.

[0022] In one embodiment, for the aforementioned working chamber 2, a fixed clamp 14 that cooperates with the movable clamp 504 is provided on one side inside the working chamber 2, a floor drain plate 15 is provided at the bottom of the working chamber 2, and an arc-shaped guide groove 16 that cooperates with the rotating shaft 703 is provided on the top side of the working chamber 2, thereby ensuring a sealed processing space. At the same time, the working chamber 2 can cooperate with the external rotating shaft 703 to realize the feeding of the grinding wheel.

[0023] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0024] In practical applications, the device is placed in the processing area. The top of the working chamber 2 is pre-installed with mounting holes (not shown in the figure), through which a coolant pipe (not shown in the figure) can be connected. During the lens grinding process, coolant is sprayed from the top to prevent dust from being stirred up and to prevent lens deformation or damage during the lens grinding process. At the same time, the drain plate 15 at the bottom of the working chamber 2 can collect coolant. The bottom of the working chamber 2 has a hollow design, and waste liquid can be collected through the drain port on the outside side (not shown in the figure).

[0025] Before the lens is placed, the L-shaped support rod 11 is inserted between the movable support rod 607 and the fixed support rod 10. Due to the supporting effect of the L-shaped support rod 11 and the tensioning effect of the tension spring 13, the flipping top plate 605 remains horizontal and stable and will not rotate. Until grinding is ready, the L-shaped support rod 11 is removed, and the pushing end 804 acts on the pushing plate 606 on one side of the flipping top plate 605, ultimately changing the angle of the flipping top plate 605.

[0026] During preparation for grinding, the microscope lens is clamped securely between the fixed clamp 14 and the movable clamp 504, and the hydraulic cylinder 502 is driven to gradually clamp the lens. Since both the fixed clamp 14 and the movable clamp 504 are circular, the grinding wheel 704 will grind the lens extending beyond the edge of the fixed clamp 14. After the lens is clamped, the knob 803 is manually adjusted. By rotating the threaded push rod 802, it slides inside the internal thread box 801. Due to the action of the bearing 806 and the annular groove 805, the indicator arrow 807 does not rotate but slides along the through groove 808, displaying the direction indicated by the bar scale 809 in real time, allowing the operator to easily read the movement distance. During the movement of the threaded push rod 802, the pushing end 804 continuously abuts against the pushing plate 606, pushing the flipping top plate 605 to rotate away from the stand 4. Simultaneously, the tension spring 13 pulls the flipping top plate 605 in the opposite direction, ensuring it remains stable until the flipping top plate 605 is adjusted to the specified distance. Then, the grinding wheel 704 is driven to grind the lens. It should be noted that the position design of the arc-shaped guide groove 16, i.e., the rotation path of the grinding wheel 704, can be changed according to actual needs (design changes are made during the production stage but cannot be changed during use). For example, when the center of the arc-shaped guide groove 16 is the same as the center of the fixed clamp 14, the grinding wheel 704 will move in a circular motion along the fixed clamp 14. When the center of the arc-shaped guide groove 16 is different from the center of the fixed clamp 14, the distance between the grinding wheel 704 and the fixed clamp 14 can be changed by adjusting the pushing positioning mechanism 8.

[0027] In summary, by utilizing the above-described technical solution of the present invention, the angle of the grinding wheel drive mechanism 7 can be manually adjusted by setting the pushing and positioning mechanism 8 and the angle flipping mechanism 6, thereby changing the angle and position of the grinding wheel 704 before, during, or after grinding. Furthermore, by using the calibrated scale lines, high-precision feed and adjustment of the grinding wheel 704 can be achieved, meeting the needs of different grinding processing scenarios. By setting the moving clamping mechanism 5 and the working chamber 2, microscope lenses of different thicknesses and sizes can be clamped, ensuring the stability of the lenses during the grinding process. Simultaneously, the protective function of the working chamber 2 prevents the spillage of lens material dust and contamination by external impurities, maximizing the safety of microscope lens processing and improving lens processing quality.
