Description

Technical Field

[0001] This application relates to lens processing apparatus, and more particularly to a base device for increasing the processing range and a lens grinding processing device. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. As the application of various optical lenses in various fields becomes increasingly widespread, the requirements for various optical lens specifications are also becoming higher. To continuously improve the overall lens effect, the design of optical paths increases the processing difficulty of lenses. This increasing processing difficulty is mainly reflected in the special characteristics of their materials and angular size. In the application of optical path design, the angular structure of lenses tends to be biased towards both extremes, with the optimal lens processing difficulty half-angle being 18–38°. In related technologies, lens processing equipment is mostly designed with the optimal angular size of 18–38° initially. Common processing equipment adapters have a cylindrical extension wall in the center of the upper surface, with a groove in the middle. The protrusion of the mold is placed into the groove, and then a bolt is engaged with a threaded hole in the extension wall that extends radially into the groove for fixation.

[0003] In the process of implementing the technical solutions of the present application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: Since the extension wall is a protruding structure, the space occupied by the extension wall is large, which will affect the processing of some extreme lenses. During the processing of lenses with a half-angle exceeding 18 to 38°, the aperture and yss cannot be in a stable state, which cannot meet the processing requirements of such lenses. Summary of the Invention

[0004] In view of this, this application provides a base device and lens grinding equipment that increase the processing range, which can compress the length of the entire base device, thereby increasing the processing range.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A base device for increasing the processing range, characterized in that: it includes a base, an adapter detachably fixedly mounted on the base, and a grinding fixture mounted on the adapter; the grinding fixture includes a grinding head and a mounting post fixedly disposed at the bottom of the grinding head and extending downward, the upper surface of the grinding head is provided with a grinding groove for placing a lens; the adapter includes a body, a first mounting hole extending vertically through the middle of the body, a second mounting hole recessed downward on the upper surface of the base, the mounting post of the grinding fixture passing through the first mounting hole from top to bottom and extending into the second mounting hole, the grinding head abutting against the upper surface of the body, at least one first threaded hole extending radially into the first mounting hole is provided on the outer peripheral wall of the body, a first screw is threadedly connected in the first threaded hole, the shank of the first screw abutting against the mounting post of the grinding fixture and locking the grinding fixture.

[0007] The aforementioned base device for increasing the processing range, by removing the protruding cylindrical structure on the adapter and providing a second mounting hole on the base, allows the mounting post of the grinding fixture to sink into the base, and the grinding head of the grinding fixture to reach the upper surface of the main body. This minimizes the overall length of the base device, thereby increasing the processing range to suit the processing of some extreme lenses. Furthermore, the grinding fixture is secured to the adapter with a first screw, and the grinding fixture can be replaced as needed during use, making it convenient to operate.

[0008] In some embodiments, the diameter of the first mounting hole is the same as the outer diameter of the mounting post, used for coaxial positioning of the grinding fixture. Since the grinding fixture may need to be replaced during use, ensuring coaxial mounting of the grinding fixture and the adapter through the first mounting hole improves replacement efficiency. Preferably, the mounting post is a cylindrical structure.

[0009] In some embodiments, the upper surface of the body is provided with at least one downwardly recessed stepped portion, the stepped portion having a through hole extending vertically, and the base having a second threaded hole corresponding to the through hole. The base and the adapter are connected by a second screw, the shank of the second screw passing through the through hole and threadedly connected to the second threaded hole, the screw head pressing against the stepped portion, and the height of the screw head being lower than the upper surface of the body. Since the base and the adapter are also connected by screws, to prevent the screw head of the second screw from protruding and hitting the grinding head, a downwardly recessed stepped portion is provided on the body. This ensures that the grinding fixture can be accurately installed and minimizes the length of the entire base device.

[0010] In some embodiments, the diameter of the through hole is larger than the diameter of the second threaded hole to allow for alignment between the base and the adapter. The diameter of the through hole is slightly larger than the second threaded hole. When the second screw is partially loosened while still connected to the second threaded hole, the relative positions of the adapter and the base can be adjusted to ensure they are on the same axis.

[0011] In some embodiments, the number of stepped portions is three, spaced apart along the circumference of the body, and the number of first threaded holes is also three, spaced apart along the circumference of the body, with the first threaded holes positioned between adjacent stepped portions. The first threaded holes and stepped portions are staggered to prevent interference between the first screw and the second screw. The number is not limited to three; it can also be four, five, or others as needed.

[0012] In some embodiments, the base, adapter, and grinding fixture are made of stainless steel or copper. These materials ensure greater stability of the base device during use.

[0013] This application also provides a lens grinding processing equipment, which has the above-mentioned base device for increasing the processing range. The equipment is characterized by further including a frame, a swing mechanism, a clamp, and a lifting mechanism. The swing mechanism is mounted on the frame, and the base of the base device is fixedly mounted on the swing mechanism. The clamp is used to hold the lens and is positioned above the grinding fixture. The lifting mechanism is connected between the frame and the clamp to drive the clamp to move up and down. When the clamp descends, it presses the lens into the grinding groove of the grinding fixture. The swing mechanism causes the entire base device to swing, thereby grinding the lens through the swing of the grinding groove.

[0014] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0015] This application discloses a base device and lens grinding equipment to increase the processing range. By removing the protruding cylindrical structure on the adapter and providing a second mounting hole on the base, the mounting post of the grinding fixture can be lowered into the base, and the grinding head of the grinding fixture reaches the upper surface of the main body. This minimizes the overall length of the base device, thereby increasing the processing range to suit the processing of some extreme lenses. Furthermore, the grinding fixture is secured to the adapter with a first screw, allowing for easy replacement of the grinding fixture as needed during use.

[0016] 2. Using this device can increase the processing range to R20 based on the original tooling, and it is applicable to different types of equipment with the same processing mode. It is also suitable for all lens processing equipment and has a wide range of applications. Using this device can achieve the optimal design value of the equipment, fundamentally solving the problem of not being able to achieve the design value of the equipment due to tooling issues. This device can save nearly 50% or more of the cost on the original products. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0024] See Figures 1 to 3This application provides a base device for increasing the processing range, including a base 1, an adapter 2 detachably fixedly mounted on the base 1, and a grinding fixture 3 mounted on the adapter 2. The grinding fixture 3 includes a grinding head 31 and a mounting post 32 fixedly disposed at the bottom of the grinding head 31 and extending downward. The upper surface of the grinding head 31 is provided with a grinding groove 33 for placing a lens 4. The adapter 2 includes a body 21, with a first mounting hole 22 extending vertically through the middle of the body 21. The upper surface of the base 1 is provided with a second mounting hole 11 recessed downward. The mounting post 32 of the grinding fixture 3 passes through the first mounting hole 22 from top to bottom and extends into the second mounting hole 11. The grinding head 31 abuts against the upper surface of the body 21. At least one first threaded hole 23 extending radially into the first mounting hole 22 is provided on the outer peripheral wall of the body 21. A first screw is threaded into the first threaded hole 23. The shank of the first screw abuts against the mounting post 32 of the grinding fixture 3 and locks the grinding fixture 3.

[0025] This base device, which increases the processing range, removes the protruding cylindrical structure on the adapter 2 and provides a second mounting hole 11 on the base 1. This allows the mounting post 32 of the grinding fixture 3 to sink into the base 1, and the grinding head 31 of the grinding fixture 3 to press against the upper surface of the body 21. This minimizes the overall length of the base device, thereby increasing the processing range to suit the processing of some extreme lenses 4. Furthermore, the grinding fixture 3 is secured to the adapter 2 with a first screw, and the grinding fixture 3 can be replaced as needed during use, making it convenient to operate.

[0026] The diameter of the first mounting hole 22 is the same as the outer diameter of the mounting post 32, used for coaxial positioning of the grinding fixture 3. Since the grinding fixture 3 may need to be replaced during use, the first mounting hole 22 ensures that the grinding fixture 3 and the adapter 2 are coaxially installed, which improves replacement efficiency. Preferably, the mounting post 32 is a cylindrical structure.

[0027] The upper surface of the body 21 is provided with at least one downwardly recessed stepped portion 24, and a through hole 25 is provided on the stepped portion 24. The base 1 is provided with a second threaded hole 12 corresponding to the through hole 25. The base 1 and the adapter 2 are connected by a second screw. The shank of the second screw passes through the through hole 25 and is threaded into the second threaded hole 12. The screw head of the second screw presses on the stepped portion 24, and the height of the screw head is lower than the upper surface of the body 21. Since the base 1 and the adapter 2 are also connected by screws, in order to avoid the screw head of the second screw protruding and hitting the grinding head 31, a downwardly recessed stepped portion 24 is provided on the body 21. This ensures that the grinding fixture 3 can be accurately installed in place and minimizes the length of the entire base device.

[0028] The diameter of the through hole 25 is larger than the diameter of the second threaded hole 12, so that the base 1 and the adapter 2 can be aligned. The diameter of the through hole 25 is slightly larger than that of the second threaded hole 12. When the second screw is loosened part of the way and is still connected to the second threaded hole 12, the relative positions of the adapter 2 and the base 1 can be adjusted to ensure that they are on the same axis.

[0029] The number of stepped portions 24 is three, spaced apart along the circumference of the body 21. The number of first threaded holes 23 is also three, spaced apart along the circumference of the body 21, and the first threaded holes 23 are located between two adjacent stepped portions 24. The first threaded holes 23 and the stepped portions 24 are staggered to avoid interference between the first screw and the second screw. The number is not limited to three; it can also be four, five, or other numbers as needed.

[0030] The base 1, adapter 2, and grinding fixture 3 are made of stainless steel or copper. These materials ensure greater stability of the base device during use.

[0031] The base device is assembled as follows: the base 1 is fixedly installed on the processing equipment, the adapter 2 is placed on the base 1, the adapter 2 and the base 1 are connected by three second screws, the coaxiality of the adapter 2 and the base 1 is adjusted and the second screws are tightened, then the mounting post 32 of the grinding fixture 3 is placed into the first mounting hole 22 and inserted into the second mounting hole 11, and the three first screws are tightened.

[0032] See Figures 4 to 5 This diagram illustrates the usage state of another embodiment of the present application. This embodiment provides a lens grinding processing device, which includes a base device for increasing the processing range as described above, and further includes a frame, a swing mechanism, a clamp 5, and a lifting mechanism. The swing mechanism is mounted on the frame, and the base 1 of the base device is fixedly mounted on the swing mechanism. The clamp 5 is used to hold the lens 4 and is positioned above the grinding fixture 3. The lifting mechanism is connected between the frame and the clamp 5 to drive the clamp 5 to move up and down. When the clamp 5 descends, it presses the lens 4 into the grinding groove 33 of the grinding fixture 3. The swing mechanism causes the entire base device to swing, thereby grinding the lens 4 through the swing of the grinding groove 33.

[0033] During use, the lifting mechanism drives the clamp 5 and lens 4 downward into the grinding groove 33, and the swing mechanism is activated to grind the lens 4 by reciprocating the swing motion of the grinding fixture 3. See [link to relevant documentation]. Figure 4 and Figure 5 The grinding process is as follows: After grinding is complete, the oscillating mechanism stops, and the lifting mechanism returns to its original position.
