Description

Technical Field

[0001] The utility model belongs to the technical field of optical lens processing devices, and particularly relates to a mirror surface grinding device for optical lenses. Background Art

[0002] An optical lens is an optical component that uses optical principles to control and manipulate light transmission through refraction and reflection. Optical lenses are based on Snell's law, which states that light refracts when it passes from one medium to another. Optical lenses exploit the phenomenon of refraction at the boundary between materials with different refractive indices to change the direction and path of light. Optical lenses can also redirect light through reflection. For example, a plane mirror reverses the direction of light by reflecting it off its surface.

[0003] In the precision manufacturing process of optical lenses, fine grinding of surface defects is a crucial step, and this process relies on polishing equipment. However, the polishing equipment currently widely used in the market generally has a design limitation: the overall height is mostly fixed and cannot be adjusted. This design ignores the significant height differences between different polishers. As a result, in actual operation, both tall workers and relatively short operators face difficulties in finding a comfortable working posture that is both ergonomic and ensures operational precision.

[0004] Specifically, for taller grinders, fixed-height grinding devices may require them to bend over or adjust to unnatural postures for extended periods of time. This not only increases the workload but can also cause fatigue and injury to the waist and neck. Conversely, shorter workers may face the dilemma of having to raise their feet or overextend their arms, which is also detrimental to improving work efficiency and ensuring safety. Utility Model Content

[0005] The purpose of this utility model is to provide a mirror polishing device for optical lenses. This device aims to address the problem that for taller workers, fixed-height polishing devices may require them to bend over or adjust to unnatural postures for extended periods of time. This not only increases the workload but can also cause fatigue and injury to the waist and neck. Conversely, shorter workers may face the dilemma of needing to elevate their feet or overextend their arms, which is also detrimental to improving work efficiency and ensuring work safety.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a mirror polishing device for an optical lens, comprising a polishing machine, grinding discs being mounted on output shafts on both sides of the polishing machine, an inner base being mounted on the bottom of the polishing machine, and the inner base being movably mounted inside the outer base;

[0007] An adjusting bolt is installed through the thread on the surface of the outer base, and the bottom of the adjusting bolt is fixedly installed in the inner ring of the bearing. The bottom outer ring of the bearing is fixedly installed on the surface of the side plate, and one side of the side plate is fixedly installed on the outer wall of the inner base.

[0008] In order to reduce the impact of vibration generated by the grinder during grinding on the optical lens, as a mirror grinding device for optical lenses of the utility model, preferably, an inward recess is opened inside the inner base, and a buffer plate is movably connected to the upper inner wall of the recess, and a convex column is connected to the bottom outer wall of the buffer plate, and the bottom of the convex column is fixedly connected to the force plate, and a spring is installed at the bottom of the force plate, and the bottom of the spring is connected to the inner wall of the inner cavity. Two groups of springs are symmetrically installed at the bottom of the force plate, and a group of convex columns are installed at equal intervals between the buffer plate and the force plate, and the convex columns are made of flexible rubber material.

[0009] In order to enable the inner base to be stably height-adjusted within the outer base, as a mirror polishing device for an optical lens of the present invention, preferably, an inner cavity is defined within the outer base, and a side groove is defined on each outer wall of the inner cavity. The inner dimensions of the inner cavity match those of the inner base, and the lateral dimensions of the side groove match those of the side plates. The vertical length of the maximum stroke of the adjustment bolt is greater than the maximum longitudinal vertical length of the side groove, and the maximum lateral vertical length of the two side plates is greater than the maximum lateral vertical length between the inner walls of the inner cavity opening.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] During use, the grinder can adjust the height of the grinder according to his or her own height. The adjustment process is as follows:

[0012] The grinder can adjust the adjustment bolt alone or in pairs. When operating alone, each adjustment bolt needs to be adjusted gradually in turn. The adjustment bolt will move outward from the inside through the threaded structure between the adjustment bolt and the outer base. When the adjustment bolt moves outward, it will drive the inner base to move outward through the bearing and the side plate. When the inner base moves outward, the height of the grinder can be adjusted upward. After the adjustment is completed, the grinder can use the grinder to grind the optical lens more comfortably, thereby improving the comfort when grinding the optical lens.

[0019] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-4 The utility model provides the following technical solutions: a mirror polishing device for an optical lens, comprising a polishing machine 1, grinding discs 2 being mounted on output shafts on both sides of the polishing machine 1, an inner base 3 being mounted at the bottom of the polishing machine 1, and the inner base 3 being movably mounted inside an outer base 4;

[0021] During use, the grinder starts the grinder 1 through the switch on the grinder 1, and the grinder 1 will drive the grinding discs 2 on both sides to rotate. At this time, the grinder can place the optical lens on the corresponding side of the grinding disc 2 for grinding according to needs, so that the defects on the optical lens can be processed.

[0022] An adjusting bolt 5 is installed through the thread on the surface of the outer base 4. The bottom of the adjusting bolt 5 is fixedly installed in the inner ring of the bearing 6. The bottom outer ring of the bearing 6 is fixedly installed on the surface of the side plate 7. One side of the side plate 7 is fixedly installed on the outer wall of the inner base 3.

[0023] Preferably: an inward recess is opened inside the inner base 3, a buffer plate 301 is movably connected to the upper inner wall of the recess, a boss 302 is connected to the bottom outer wall of the buffer plate 301, the bottom of the boss 302 is fixedly connected to the force plate 303, a spring 304 is installed at the bottom of the force plate 303, the bottom of the spring 304 is connected to the inner wall of the inner cavity 401, two groups of springs 304 are symmetrically installed at the bottom of the force plate 303, a group of bosses 302 are installed at equal intervals on the buffer plate 301 and the force plate 303, and the bosses 302 are made of flexible rubber material.

[0024] When in use, the grinder can operate the grinder 1 alone by adjusting the gap of each adjusting pin 5 in turn multiple times to gradually adjust the adjusting pin 5 upwards. When the adjusting pin 5 moves upwards, it drives the side plate 7 to move upwards through the bearing 6. When the side plate 7 moves upwards, it drives the inner base 3 to move.

In this way, the height of the grinder 1 can be adaptively adjusted, so that grinders of different heights can also comfortably operate the grinder 1 to grind optical lenses.

[0025] When the grinder 1 grinds the optical lens, it will generate vibrations. The vibrations generated by the grinder 1 will be transmitted to the buffer plate 301, the boss 302, the force plate 303 and the spring 304 through the inner base 3. After this round of transmission, the vibration force of the grinder 1 will be greatly weakened. In this way, the stability of the grinder 1 during operation can be improved through this structure.

The internal size of the inner cavity 401 is adapted to the size of the inner base 3 , and the lateral size of the side groove 402 is adapted to the lateral size of the side plate 7 .

[0027] During specific use, when the adjusting bolt 5 drives the side plate 7 to move upward, the outer wall of the side plate 7 will move along the outer wall of the side groove 402, which can ensure the stability of the inner base 3 when moving in the outer base 4.

[0028] Preferably, the vertical length of the maximum stroke of the adjusting bolt 5 is greater than the maximum longitudinal vertical length of the side groove 402 , and the maximum transverse vertical length of the two side plates 7 is greater than the maximum transverse vertical length between the inner walls of the opening of the inner cavity 401 .
