Description

Technical Field

[0001] This utility model relates to the field of eyeglasses processing technology, specifically to a grooving tool for processing eyeglass frames. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct various vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia, strabismus, and amblyopia. Depending on their purpose, eyeglasses are categorized as nearsighted glasses, farsighted glasses, reading glasses, and astigmatism glasses, among others.

[0003] Eyeglass frames consist of parts such as the frame and temples. The inner wall of the frame typically has slots for lens mounting, which require cutting tools. Since users have different eye prescriptions and require different lens thicknesses, sometimes the slots need to be widened during the fitting process. Current cutting tools for machining lens slots usually lack positioning and limiting functions. If the operator is careless, they may damage the slots, leading to a mismatch between the slot and the lens, making lens installation inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a grooving tool for processing picture frames, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grooving tool for processing eyeglass frames, comprising a handle and a cutting tool assembly disposed on the handle. The cutting tool assembly includes a rotating shaft, a circular cutting blade, limiting discs A and B respectively located on the left and right sides of the circular cutting blade, a positioning disc fixedly disposed on the left end of the handle, a screw, and a grinding assembly. The handle is hollow, and the rotating shaft is located inside the handle and rotatably connected to it. A mounting sleeve extending out of the handle is fixedly disposed on the left end of the rotating shaft. The circular cutting blade, limiting discs A and B are all provided with through holes on the left and right sides. The mounting sleeve is inserted into the through holes and contacts and connects with the circular cutting blade, limiting discs A and B. The inner side of the mounting sleeve is threaded, and the screw is screwed into the mounting sleeve and fixedly connected to the limiting disc A. The positioning disc abuts against the limiting disc B. The diameter of the positioning disc is larger than the diameter of the circular cutting blade, and the diameter of the circular cutting blade is larger than the diameters of the limiting discs A and B.

[0006] Preferably, the grinding assembly includes a grinding disc, a connecting disc, and a plurality of screws. The limiting disc A has a plurality of screw holes extending through it in both the left and right directions. Both the grinding disc and the connecting disc have a plurality of through holes A extending through it in both the left and right directions. The screws are inserted into the through holes A and then screwed into the screw holes to fix them to the grinding disc. The connecting disc is located between the grinding disc and the limiting disc A. Both the grinding disc and the connecting disc have through holes B extending through it in both the left and right directions. The diameter of the through holes B is larger than the diameter of the screws.

[0007] Preferably, a plurality of positioning pins A and B are fixedly provided on the left and right sides of the connecting plate, and a plurality of positioning holes A and B are respectively opened on the right side wall of the grinding plate and the left side wall of the limiting plate A. The positioning pins A and B are respectively inserted into the positioning holes A and B and contact and connect with the grinding plate and the limiting plate A. After the positioning pins A and B are respectively inserted into the positioning holes A and B, the through hole A is aligned with the screw hole.

[0008] Preferably, the cutter assembly further includes several bearings fixedly disposed inside the handle, the rotating shaft is rotatably connected to the handle through the bearings, and the handle is provided with a drive component for driving the rotating shaft to rotate, the rotating shaft being connected to the drive component.

[0009] Preferably, the cutter assembly further includes a flat washer and a spring washer sleeved on the screw, the spring washer being located between the screw head and the flat washer, and the flat washer being fixedly connected to the limiting plate A after the screw is screwed into the mounting sleeve.

[0010] Preferably, the mounting sleeve is fixedly provided with an insert block, and the circular cutter, limiting plate A and limiting plate B are all provided with slots that extend through to the left and right. The insert block is inserted into the slot and abuts against the circular cutter, limiting plate A and limiting plate B.

[0011] Preferably, the outer side of the handle is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are as follows: When using this utility model, the starter drives the rotating shaft to rotate, which in turn rotates the mounting sleeve and the circular cutter mounted on it. The circular cutter is placed into the frame, and the positioning plate contacts and connects with the right side wall of the frame. Then, the handle is moved downwards to move the circular cutter downwards, allowing it to insert into the frame's groove for cutting and widening. When moving the circular cutter, the positioning plate remains in contact with the frame, thus preventing the circular cutter from tilting and avoiding damage to the groove. If the operator accidentally moves the circular cutter downwards excessively, the limiting plates A and B will abut against the inner side wall of the frame, preventing the circular cutter from damaging the inner side wall. The excessive cutting of the lens groove prevents it from being cut through. After cutting, the edge of the lens groove is relatively sharp, which is not conducive to lens installation and requires grinding. Since the grinding disc and connecting disc are fixed to the limiting disc A, the rotation of the shaft will drive the grinding disc to rotate, moving the grinding disc to the lens groove, so that the edge of the lens groove can be ground. In summary, this utility model has the beneficial effect of avoiding damage to the lens groove, and solves the problem that existing tools for processing lens grooves usually do not have positioning and limiting functions. If the operator is not careful, the lens groove may be damaged, resulting in the lens groove and lens mismatch, which makes it inconvenient to install the lens. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figure 1-5As shown, this utility model discloses a grooving tool for processing eyeglass frames, including a handle 1, a cutting tool assembly disposed on the handle 1, the cutting tool assembly including a rotating shaft 2, a circular cutter 3, limiting plates A4 and B5 respectively located on the left and right sides of the circular cutter 3, a positioning plate 6 fixedly disposed on the left end of the handle 1, a screw 7, and a grinding assembly. The handle 1 is hollow, the rotating shaft 2 is located inside the handle 1 and rotatably connected to the handle 1, and a protruding part is fixedly disposed on the left end of the rotating shaft 2 extending out of the handle 1. The mounting sleeve 8 has insertion holes 9 through the circular cutter 3, the limiting plate A4, and the limiting plate B5 on both sides. The mounting sleeve 8 is inserted into the insertion holes 9 and makes contact with the circular cutter 3, the limiting plate A4, and the limiting plate B5. The mounting sleeve 8 has threads on its inner side. The screw 7 is screwed into the mounting sleeve 8 and fixedly connected to the limiting plate A4. The positioning plate 6 is in contact with the limiting plate B5. The diameter of the positioning plate 6 is larger than the diameter of the circular cutter 3. The diameter of the circular cutter 3 is larger than the diameter of the limiting plate A4 and the limiting plate B5. During assembly, the mounting sleeve 8 is inserted into the insertion hole 9 to connect with the circular cutter 3, the limiting plate A4, and the limiting plate B5. The insert block 23 is then inserted into the slot 24 to abut against the circular cutter 3, the limiting plate A4, and the limiting plate B5. Next, the screw 7 is screwed into the mounting sleeve 8 to fix it to the limiting plate A4. The screw 7 will press the circular cutter 3, the limiting plate A4, and the limiting plate B5 against the left end of the rotating shaft 2, completing the installation of the circular cutter 3. After inserting the screw 12 into the through hole A14, it is screwed into the screw hole 13 for grinding. The grinding disc 10 is fixedly connected, and the screw 12 will press the grinding disc 10 and the connecting disc 11 against the left end of the limiting disc A4, completing the installation of the grinding disc 10 and thus completing the assembly of this utility model. When using this utility model, the starter drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the mounting sleeve 8 and the circular cutter 3 mounted on it to rotate, placing the circular cutter 3 into the frame and making the positioning disc 6 contact and connect with the right side wall of the frame. Then, the handle 1 is moved downward to move the circular cutter 3 downward, so that the circular cutter 3 is inserted. The lens groove of the lens frame is widened by cutting. When the circular cutter 3 is moved, the positioning plate 6 is kept in contact with the lens frame to prevent the circular cutter 3 from tilting and thus avoid damaging the lens groove. If the operator accidentally moves the circular cutter 3 too far downward, the limiting plate A4 and the limiting plate B5 will abut against the inner wall of the lens frame to prevent the circular cutter 3 from over-cutting the lens groove and thus prevent the lens groove from being cut through. After the lens groove is cut, the edge is relatively sharp, which is not conducive to lens installation and requires grinding. Since the grinding plate 10 and the connecting plate 11 are fixed to the limiting plate A4, the rotation of the rotating shaft 2 will drive the grinding plate 10 to rotate, move the grinding plate 10 to the lens groove, and then grind the edge of the lens groove. In summary, this utility model has the beneficial effect of avoiding damage to the lens groove and solves the problem that the existing tools for processing lens grooves usually do not have positioning and limiting functions. If the operator is not careful, the lens groove may be damaged, resulting in the lens groove not matching the lens and making it inconvenient to install the lens.

[0017] Preferably, the grinding assembly includes a grinding disc 10, a connecting disc 11, and a plurality of screws 12. The limiting disc A4 has a plurality of threaded holes 13 extending through it horizontally. Both the grinding disc 10 and the connecting disc 11 have a plurality of through holes A14 extending through it horizontally. The screws 12 are inserted into the through holes A14 and then screwed into the threaded holes 13 to fix them to the grinding disc 10. The connecting disc 11 is located between the grinding disc 10 and the limiting disc A4. Both the grinding disc 10 and the connecting disc 11 have through holes B15 extending through it horizontally. The diameter of the through hole B15 is larger than the diameter of the screws 7. Because the screws 12 are inserted into the through holes A14 and then screwed into the threaded holes 13 to fix them to the grinding disc 10, this facilitates the disassembly and assembly of the grinding disc 10. Because the diameter of the through hole B15 is larger than the diameter of the screws 7, when disassembling and assembling the circular cutter 3, inserting a tool into the through hole B15 allows for the unscrewing of the screws 7, thus facilitating the disassembly and assembly of the circular cutter 3 and enabling the replacement of circular cutters 3 of different sizes.

[0018] Preferably, the connecting disc 11 is fixedly provided with a plurality of positioning posts A16 and B17 on its left and right sides, respectively. The right side wall of the grinding disc 10 and the left side wall of the limiting disc A4 are respectively provided with a plurality of positioning holes A18 and B19. The positioning posts A16 and B17 are inserted into the positioning holes A18 and B19, respectively, to contact and connect with the grinding disc 10 and the limiting disc A4. After the positioning posts A16 and B17 are inserted into the positioning holes A18 and B19, respectively, the through hole A14 is aligned with the screw hole 13. Since the positioning posts A16 and B17 are inserted into the positioning holes A18 and B19, respectively, and the through hole A14 is aligned with the screw hole 13, this facilitates the positioning and installation of the grinding disc 10.

[0019] Preferably, the cutter assembly further includes several bearings 20 fixedly disposed inside the handle 1. The rotating shaft 2 is rotatably connected to the handle 1 through the bearings 20. The handle 1 has a drive component for driving the rotating shaft 2 to rotate, and the rotating shaft 2 is connected to the drive component. The drive component is an electric motor (not shown in the figure). The rotating shaft 2 is fixedly connected to the output shaft of the drive component. The drive component is connected to a switch and a power supply through wires. (The functions to be achieved by each piece of hardware in this utility model are supported by a large number of mature technologies. The essence of this utility model is that for specific application scenarios, the above connection and control methods are all existing technologies and do not involve the modification of the internal software of the hardware.)

[0020] Preferably, the cutter assembly further includes a flat washer 21 and a spring washer 22 sleeved on the screw 7. The spring washer 22 is located between the screw head of the screw 7 and the flat washer 21. After the screw 7 is screwed into the mounting sleeve 8, the flat washer 21 is fixedly connected to the limiting plate A4. Since the spring washer 22 is located between the screw head of the screw 7 and the flat washer 21, it plays a role in preventing loosening and resisting vibration.

[0021] Preferably, the mounting sleeve 8 is fixedly provided with an insert block 23. The circular cutter 3, the limiting plate A4, and the limiting plate B5 are all provided with slots 24 extending through to the left and right. The insert block 23 is inserted into the slot 24 and abuts against the circular cutter 3, the limiting plate A4, and the limiting plate B5. Since the insert block 23 is inserted into the slot 24 and abuts against the circular cutter 3, the limiting plate A4, and the limiting plate B5, when the rotating shaft 2 rotates, it drives the mounting sleeve 8 to rotate. The mounting sleeve 8 drives the circular cutter 3, the limiting plate A4, and the limiting plate B5 to rotate through the insert block 23, which facilitates the rotation of each part.

[0022] Preferably, the outer side of the handle 1 is provided with anti-slip texture 25. Because the outer side of the handle 1 is provided with anti-slip texture 25, it plays a role in preventing slippage.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
