Description

Technical Field

[0001] This invention relates to the field of polishing and grinding technology, and in particular to a polishing and grinding device for processing convex lenses for automotive headlights. Background Technology

[0002] A convex lens for automotive headlights has one convex side and one concave side. In actual use, it is fixed to a lens frame and installed on both sides of the driver's cab to observe blind spots, enhancing driving safety. To enable polishing of both sides of the convex lens, Chinese Patent Application No. 202210865273.7 discloses a polishing device for processing automotive headlight convex lenses. This device includes a horizontally mounted base plate, on which are respectively provided a support assembly, a clamping mounting assembly, a concave surface polishing assembly, and a convex surface polishing assembly. The support assembly includes two vertical support side plates symmetrically fixed to the upper surface of the mounting base plate. The support assembly also includes a support base fixed to the center of the upper surface of the mounting base plate. The clamping mounting assembly includes a clamping cylinder rotatably mounted above the support base. The clamping cylinder has an open upper end and a closed lower end. Several centrally symmetrical clamping telescopic cylinders are fixed to the inner bottom surface of the clamping cylinder. Several detachable clamping blocks are provided on the outer wall of the open end of the clamping cylinder.

[0003] While the aforementioned patent addresses the issues of low polishing efficiency and poor polishing effect in traditional polishing and grinding devices for automotive headlight convex lenses, its structure requires numerous telescopic cylinders with various clamping structures to hold both sides of the convex lens, resulting in a complex mechanical structure. Furthermore, ensuring the segmented polishing brushes are evenly applied to the lens surface necessitates high precision in the telescopic cylinders' extension and retraction, making assembly difficult. Additionally, the polishing fluid is quickly depleted when added, leading to high polishing costs. Summary of the Invention

[0004] To address the issues of high equipment cost, complex structure, and difficulty in controlling polishing fluid usage, the present invention provides the following technical solution based on the principle of steel grit polishing: A polishing and grinding device for processing convex lenses for automotive headlights includes a base, a vibration mechanism within the base, a first spring seat mounted on the top of the base, a vibration plate mounted on the top of the first spring seat, a second spring seat mounted on the top surface of the vibration plate, a vibration chamber mounted on the top of the second spring seat, a polishing cavity within the vibration chamber, a polishing fluid supply chamber within the polishing cavity, a controllable mechanism surrounding the polishing fluid supply chamber, and several leakage holes formed on the chamber wall of the polishing fluid supply chamber. The controllable mechanism includes a controllable plate, one end of which is connected to the base, and the other end of which surrounds the outer surface of the polishing fluid supply chamber with a movable gap between it and the outer surface of the polishing fluid supply chamber. The controllable mechanism also includes... The system includes a rubber tube fixed to each of the leakage holes, and several insertion tubes fixed to the inner wall of the controllable plate. Each insertion tube corresponds to one rubber tube. The controllable plate deflects along the movable gap toward the outer surface of the polishing fluid supply chamber. When the insertion tube is inserted into the corresponding rubber tube, the polishing fluid supply chamber is connected to the insertion tube through the rubber tube, so that the polishing fluid in the polishing fluid supply chamber flows into the polishing chamber. The polishing chamber is filled with fine steel grit as a polishing medium. When the fine steel grit vibrates through the polishing chamber, it not only polishes the surface of the convex lens, but also transmits the vibration to the controllable plate through the fine steel grit, so that the controllable plate deflects relative to the polishing fluid supply chamber along the movable gap.

[0005] As a further preferred embodiment, the vibration mechanism includes a vibration motor fixed in the base and a connecting rod structure connected to the eccentric wheel of the vibration motor. The other end of the connecting rod structure is hinged upward to the bottom surface of the vibration plate to provide vibration to the vibration plate.

[0006] As a further preferred embodiment, the vibration chamber has a partial discharge port, the vibration chamber is provided with a discharge plate, the discharge plate is located in the polishing cavity, the discharge end of the discharge plate reaches the discharge port, and the inlet end of the discharge plate is close to the middle of the polishing cavity.

[0007] As a further preferred embodiment, the bottom surface of the discharge plate is higher than the bottom of the polishing chamber, and a material storage space is formed between the discharge plate and the bottom of the polishing chamber. The fixed end of the controllable plate is close to the feed end of the discharge plate, and the free end of the controllable plate is close to the discharge port.

[0008] As a further preferred embodiment, a ramp plate is provided between the feed end of the discharge plate and the bottom of the polishing cavity. The ramp plate is a ladder structure, with one end of the ramp plate inclined downward and placed at the bottom of the polishing cavity, and the other end of the ramp plate inclined upward and connected to the feed end of the discharge plate.

[0009] As a further preferred embodiment, both the discharge plate and the ramp plate are provided with a large number of drainage holes.

[0010] As a further preferred embodiment, a rubber plate is installed on the inner wall of the vibration chamber, with one end of the rubber plate close to the feed end of the discharge plate and the other end of the rubber plate close to the discharge end of the discharge plate. The controllable plate is disposed opposite to the inner circumference of the rubber plate, and the inner surface of the rubber plate is an inclined surface that gradually slopes inward toward the free end of the controllable plate, so that the polishing cavity gradually narrows from the fixed end of the controllable plate to the free end.

[0011] As a further preferred embodiment, the outer wall of the polishing fluid supply chamber is provided with a semi-circular recessed cavity, the polishing fluid supply chamber is located in the recessed cavity, an ear seat is fixed on the base, the ear seat is on the same side as the fixed end of the controllable plate, a vertically upward support rod is fixed on the ear seat, a carrier plate is fixed at the top of the support rod, a vertically downward connecting rod is fixed along the top of the discharge plate to the top of the polishing fluid supply chamber, and the controllable plate is a spring plate, the fixed end of the controllable plate is connected to the connecting rod.

[0012] The advantages of this invention compared to the prior art are: 1. The lens is inserted into the steel grit, so the steel grit will thoroughly polish the mirror surface when it vibrates in the polishing chamber 7. This polishing method does not require the lens to be clamped by a complex clamping structure as in the prior art, nor does it require a large number of complex telescopic cylinders to push the polishing brush on the mirror surface according to the concave and convex shape of the mirror surface. In comparison, the steel grit in this invention has better fluidity, and the polishing effect generated by vibration can accelerate the polishing efficiency of the mirror surface. Moreover, the structure of this invention is simple.

[0013] In addition, the steel shot inevitably impacts the control plate when it vibrates within the polishing chamber. Each vibration causes the control plate to deflect back and forth once relative to the outer surface of the polishing fluid supply chamber. The control plate has numerous insertion tubes, while the polishing fluid supply chamber has numerous rubber tubes positioned relative to these tubes. These rubber tubes have slits in the middle; when the slits open, the tubes are unblocked, allowing the polishing fluid in the supply chamber to flow into the polishing chamber. The control plate performs this function. When the control plate deflects towards the polishing fluid supply chamber… Simultaneously, insert cannulas are inserted into each rubber tube to fully expand all the rubber tubes. The inner ends of all cannulas are inserted into the polishing fluid supply chamber, allowing the polishing fluid in the supply chamber to flow into the polishing cavity in a controllable manner until most of the steel grit is coated with polishing fluid. As vibration continues, the polishing fluid is applied to the mirror surface, assisting in the rapid polishing of the lens. Compared with the prior art, the polishing fluid in this invention is controlled and will not be used up at once. In addition to most of the steel grit being coated with polishing fluid as it vibrates, the coating is relatively uniform when the steel grit polishes the mirror surface, thus accelerating the polishing efficiency.

[0016] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] In one implementation, such as Figures 1-6As shown: This embodiment provides a polishing and grinding device for processing automotive headlight convex lenses, including a base 1, a vibration mechanism 2 inside the base 1, a first spring seat 3 mounted on the top of the base 1, a vibration plate 4 mounted on the top of the first spring seat 3, a second spring seat 5 mounted on the top surface of the vibration plate 4, a vibration chamber 6 mounted on the top of the second spring seat 5, a polishing cavity 7 inside the vibration chamber 6, a polishing fluid supply chamber 8 inside the polishing cavity 7, a controllable mechanism 9 around the polishing fluid supply chamber 8, and several leakage holes 10 opened on the chamber wall of the polishing fluid supply chamber 8. The controllable mechanism 9 includes a controllable plate 91, one end of which is connected to the base 1. The other end of the controllable plate 91 surrounds the outer surface of the polishing fluid supply chamber 8 and leaves an movable gap 11 between it and the outer surface of the polishing fluid supply chamber 8. The controllable mechanism 9 also includes a rubber tube 92 fixed on each leakage hole 10, and a number of insertion tubes 93 fixed on the inner wall of the controllable plate 91. Each insertion tube 93 corresponds to a rubber tube 92. When the controllable plate 91 deflects towards the outer surface of the polishing fluid supply chamber 8 along the movable gap 11 and inserts the insertion tube 93 into the corresponding rubber tube 92, the polishing fluid supply chamber 8 can be connected to the insertion tube 93 through the rubber tube 92 to allow the polishing fluid in the polishing fluid supply chamber 8 to flow into the polishing chamber 7. The polishing chamber 7 is filled with fine steel grit as a polishing medium. When the fine steel grit vibrates through the polishing chamber 7, it not only polishes the surface of the convex lens, but also transmits the vibration to the controllable plate 91 through the fine steel grit, so that the controllable plate 91 deflects relative to the polishing liquid supply chamber 8 along the movable gap 11. The vibration mechanism 2 includes a vibration motor 201 fixed in the base 1 and a connecting rod structure 202 connected to the eccentric wheel of the vibration motor 201. The other end of the connecting rod structure 202 is hinged upward to the bottom surface of the vibration plate 4 to provide vibration to the vibration plate 4.

[0018] In use, fine steel grit is poured into the polishing chamber 7, and the lens to be polished is inserted into the steel grit. The vibration motor 201 is energized, causing the eccentric wheel to rotate. The eccentric wheel drives the vibration plate 4 to vibrate through the connecting rod structure 202. The vibration plate 4 drives the vibration chamber 6 to vibrate, and the vibration chamber 6 drives the fine steel grit in the polishing chamber 7 to vibrate. Since the lens is inserted into the steel grit, the steel grit will thoroughly polish its mirror surface when it vibrates in the polishing chamber 7. This polishing method does not require the lens to be clamped by a complex clamping structure as in the prior art, nor does it require a large number of complex telescopic cylinders to push the polishing brush against the mirror surface according to the concave and convex shape of the mirror surface. In comparison, the steel grit in this invention has better fluidity, and the polishing effect generated by vibration can accelerate the polishing efficiency of the mirror surface. Moreover, the structure of this invention is simple.

[0019] In addition, when the steel grit vibrates within the polishing chamber 7, it inevitably impacts the controllable plate 91. One end of the controllable plate 91 is fixed, while the other end is free, leaving a movable gap 11 between it and the outer surface of the polishing fluid supply chamber 8. Therefore, the vibration generated by the steel grit, besides polishing the mirror surface, also transmits the vibration effect to the controllable plate 91. As the vibration frequency increases, the controllable plate 91 vibrates. Since the controllable plate 91 surrounds the polishing fluid supply chamber 8, it deflects relative to the outside of the chamber. That is, when the outer surface of the controllable plate 91 is vibrated by the steel grit, it deflects towards the polishing fluid supply chamber 8. When this vibration frequency disappears, the controllable plate 91 rotates away from the polishing fluid supply chamber 8. Each time the steel grit vibrates, the controllable plate 91 deflects back and forth once relative to the outer surface of the polishing fluid supply chamber 8. Because the controllable plate 91 is equipped with a large number of insertion tubes 93, and the polishing... The liquid supply chamber 8 is equipped with a large number of rubber tubes 92 relative to these insertion tubes 93. These rubber tubes 92 have slits in the middle (similar to rubber plugs). When the slits in the middle are opened, the rubber tubes 92 are opened, and the polishing liquid in the polishing liquid supply chamber 8 flows into the polishing chamber 7 through the rubber tubes 92. The control plate 91 can realize this function. When the control plate 91 deflects in the direction of the polishing liquid supply chamber 8, it will insert the insertion tubes 93 into each rubber tube 92, open the slits of the rubber tubes 92, and at the same time, the inner end of the insertion tube 93 is inserted into the polishing liquid supply chamber 8. As the vibration disappears, the free end of the control plate 91 will automatically spring back and pull the insertion tube 93 out of the rubber tube 92. The slits of the rubber tubes 92 will close again due to the rubber properties, and the polishing liquid in the polishing liquid supply chamber 8 will no longer be supplied. Waiting for the next vibration, when the control plate 91 moves towards the outer wall of the polishing liquid supply chamber 8 again, it will open the slits of the rubber tubes 92 again and supply liquid to the outside again. The polishing slurry flows into the polishing chamber 7 through the insertion tube 93. When the steel grit tumbles in the polishing chamber 7 due to vibration, it will pick up the polishing slurry onto the grit. As the number of vibrations increases, the deflection of the control plate 91 also increases. The control plate 91, along with the insertion tube 93, inserts into the rubber tube 92, and the number of times it draws liquid from the polishing slurry supply chamber 8 into the polishing chamber 7 also increases. By utilizing the vibration frequency of the steel grit on the control plate 91, the polishing slurry in the polishing slurry supply chamber 8 flows into the polishing chamber 7 in a controllable manner until most of the steel grit is covered with polishing slurry. With continued vibration, the polishing slurry is coated onto the mirror surface, assisting in the rapid polishing of the lens. Compared with the prior art, the polishing slurry in this invention is controlled and will not be used up at once. In addition to most of the steel grit being covered with polishing slurry due to vibration, the coating of the slurry is relatively uniform when the steel grit polishes the mirror surface, thus accelerating the polishing efficiency.

[0020] like Figure 1 , Figure 2 as well as Figure 6As shown, a discharge port 12 is provided at a local location in the vibration chamber 6. A discharge plate 13 is provided inside the vibration chamber 6 and is located inside the polishing chamber 7. The discharge end of the discharge plate 13 reaches the discharge port 12, and the feed end of the discharge plate 13 is close to the middle of the polishing chamber 7. The bottom surface of the discharge plate 13 is higher than the bottom of the polishing chamber 7, forming a storage space 14 between them. The fixed end of the controllable plate 91 is close to the feed end of the discharge plate 13, and the free end of the controllable plate 91 is close to the discharge port 12. A ramp plate 16 is provided between the feed end of the discharge plate 13 and the bottom of the polishing chamber 7. The ramp plate 16 has a ladder structure. One end of the ramp plate 16 is inclined downward and placed at the bottom of the polishing chamber 7, and the other end of the ramp plate 16 is inclined upward and connected to the feed end of the discharge plate 13. Both the discharge plate 13 and the ramp plate 16 have a large number of drainage holes 17. After polishing for a period of time, the ramp plate 16 is pressed down... Figure 1 The sample is placed on the feed end of the discharge plate 13 as shown. When the vibration chamber 6 vibrates, it will vibrate the ramp plate 16 together. The steel shot will also move towards the ramp plate 16. However, the steel shot has a smaller mesh size and will pass through the hole 17 to continue into the storage space 14. The lens size is larger than the hole 17, so the lens will move up the ramp plate 16 to the discharge plate 13 with the vibration. The discharge plate 13 gradually tilts downward towards the discharge port 12, and the lens will be discharged from the discharge port 12 along the discharge plate 13, completing the discharge.

[0021] It should be noted that when filling the polishing chamber 7, the steel grit is filled throughout the entire circumference, that is, the storage space 14 is also filled with steel grit. When the ramp plate 16 is not placed, the vibration effect generated by the vibration chamber 6 is transmitted to the steel grit, and then to the lens to polish the mirror surface. The lens will also vibrate with the steel grit, but the steel grit will flow along the mirror surface, and the steel grit accumulated on the mirror surface has a large gravity, so it can polish the mirror surface.

[0022] A rubber plate 18 is installed on the inner wall of the vibration chamber 6. One end of the rubber plate 18 is close to the feed end of the discharge plate 13, and the other end of the rubber plate 18 is close to the discharge end of the discharge plate 13. The control plate 91 is arranged on the inner circumference of the rubber plate 18. The inner surface of the rubber plate 18 is a slope that gradually slopes inward toward the free end of the control plate 91, so that the polishing chamber 7 gradually narrows from the fixed end of the control plate 91 to the free end. The steel grit in the narrower area generates a larger force when vibrating, which acts on the control plate 91 and makes the control plate 91 deflect and float more obviously toward the polishing liquid supply chamber 8. There is enough deflection force to make the control plate 91 insert the insertion tube 93 into the corresponding rubber tube 92. At the same time, the rubber plate 18 uses its flexibility to prevent premature wear of the steel grit.

[0023] The outer wall of the polishing fluid supply chamber 8 is provided with a semi-circular recessed cavity 19. The polishing fluid supply chamber 8 is located inside the recessed cavity 19. An ear seat 20 is fixed on the base 1. The ear seat 20 is on the same side as the fixed end of the controllable plate 91. A vertically upward support rod 21 is fixed on the ear seat 20. A carrier plate 22 is fixed to the top of the support rod 21, extending along the top of the discharge plate 13 to the top of the polishing fluid supply chamber 8, and a vertically downward connecting rod 23 is fixed thereon. The controllable plate 91 is a spring plate, and the fixed end of the controllable plate 91 is connected to the connecting rod 23. Since the controllable plate 91 is connected to the connecting rod 23, and since the connecting rod 23 is connected to the ear seat 20, and since the ear seat 20 is fixed to the base 1, the base 1 is fixed to the foundation. When the vibration chamber 6 vibrates, the vibration effect is not directly transmitted to the controllable plate 91. Only when the steel grit vibrates is the vibration effect transmitted to the controllable plate 91 by the steel grit. This is to prevent the controllable plate 91 from vibrating at the same frequency as the vibration chamber 6, which would cause the controllable plate 91 to lose its deflection effect relative to the outside of the polishing fluid supply chamber 8. This ensures that when the controllable plate 91 is deflected by the vibration of the steel grit, the insertion tube 93 is inserted into the corresponding rubber tube 92 on the rubber plate 18, so that the polishing fluid in the polishing fluid supply chamber 8 flows to the steel grit in a controlled manner.
