[0036] In one embodiment, for the above-mentioned push-to-position positioning mechanism 8, the push-to-position positioning mechanism 8 includes an internal thread box 801 arranged at the top of the stand 4, a threaded push rod 802 is arranged inside the internal thread box 801, a knob 803 is arranged at the end of the threaded push rod 802 away from the base 3, a push-to-position end 804 is arranged at the end of the threaded push rod 802 close to the base 3, an annular groove 805 is provided in the middle position of the threaded push rod 802, a bearing 806 is sleeved on the outer side of the circumference of the annular groove 805, an indication arrow 807 is arranged on the top of the bearing 806, a through groove 808 matching the indication arrow 807 is provided on the top of the internal thread box 801, and bar scales 809 are arranged on both sides of the through groove 808, so that the threaded push rod 802 and the internal thread box 801 can be used to drive the push-to-position end 804 to slide horizontally and resist the push-to-position plate 606 on one side of the flip top plate 605 for rotation adjustment.

[0037] In one embodiment, for the above-mentioned stand 4, a side bottom plate 9 is provided on one side of the top of the stand 4, and a fixed rod frame 10 is provided on the side of the side bottom plate 9 close to the base 3, and an L-shaped support rod 11 is provided between the fixed rod frame 10 and the movable rod frame 607; a fixed lifting ring 12 is provided on the bottom of the side of the stand 4 close to the base 3, and a tensioning spring 13 is provided between the fixed lifting ring 12 and the movable lifting ring 608, so that with the help of the tensioning spring 13, the flip top plate 605 is always pulled close to the stand 4, so that the push end 804 and the push plate 606 maintain close contact.

[0038] In one embodiment, for the above-mentioned working bin 2, a fixed clamp 14 cooperating with the movable clamp 504 is provided on one side inside the working bin 2, a floor drain plate 15 is provided at the bottom of the working bin 2, and an arc-shaped guide groove 16 cooperating with the rotating shaft 703 is opened on the top of one side of the working bin 2, thereby ensuring a sealed processing space. At the same time, the working bin 2 can cooperate with the external rotating shaft 703 to realize grinding wheel feeding.

[0039] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0040] In actual application, the device is placed in the area to be processed. The top of the working chamber 2 is pre-installed with a mounting hole (not marked in the figure), which can be connected to a coolant pipe (not shown in the figure). During the lens grinding process, the top is sprayed with coolant to avoid dust from being raised and to avoid deformation or damage to the lens during the lens grinding process. At the same time, the floor drain plate 15 at the bottom of the working chamber 2 can collect coolant. The bottom of the working chamber 2 is a hollow design, and waste liquid can be collected through a sewage outlet (not marked in the figure) on one side of the outside.

[0041] Before the lens is placed, the L-shaped support rod 11 is inserted between the movable rod rack 607 and the fixed rod rack 10. Due to the support of the L-shaped support rod 11 and the tension of the tension spring 13, the flip top plate 605 remains horizontal and stable and does not rotate. When grinding is ready, the L-shaped support rod 11 is removed, and the push plate 606 on one side of the flip top plate 605 is acted on by the push end 804, and finally the angle of the flip top plate 605 is changed.

[0042] When preparing for grinding, the microscope lens is completely clamped between the fixed clamp 14 and the movable clamp 504, and the oil cylinder 502 is driven to gradually clamp the lens. Since both the fixed clamp 14 and the movable clamp 504 are circular in design, the grinding wheel 704 will grind the lens beyond the edge of the fixed clamp 14. After the lens is clamped, the knob 803 is manually adjusted, and the threaded push rod 802 is rotated to slide 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, and displays the pointing bar scale 809 in real time, so that the operator can read the moving distance. During the movement of the threaded push rod 802, the push end 804 contacts the push plate 606 in real time, and pushes the flip top plate 605 to rotate in the direction away from the stand 4, and at the same time, the tension spring 13 tightens the flip top plate 605 in the opposite direction to ensure that it is always in a stable state until the flip top plate 605 is adjusted to a specified distance, and then the lens is ground by driving the grinding wheel 704. It should be noted that the position design of the arc guide groove 16, that is, the rotation path of the grinding wheel 704, can be changed according to actual needs (design changes are made in the production stage and cannot be changed during use). For example, when the center of the arc guide groove 16 is the same as the center of the fixed clamp 14, the movement of the grinding wheel 704 will make a circular motion along the fixed clamp 14. When the center of the arc 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 push positioning mechanism 8.

[0043] In summary, with the aid of the above technical solution of the utility model, by setting the push positioning mechanism 8 and the angle flip mechanism 6, the angle of the grinding wheel driving mechanism 7 can be manually adjusted, thereby changing the angle and position of the grinding wheel 704 before and after grinding or during the grinding process, and with the aid of the calibrated scale line, the high-precision feeding and adjustment of the grinding wheel 704 can be achieved to meet different grinding processing scenarios. By setting the mobile clamping mechanism 5 and the working chamber 2, it is possible to clamp microscope lenses of different thicknesses and sizes to ensure the stability of the lenses during the grinding process. At the same time, with the aid of the protective effect of the working chamber 2, it is possible to avoid the spillage of lens material dust and the pollution of external impurities, thereby ensuring the safety of microscope lens processing to the greatest extent and improving the lens processing quality.
