Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for optical lens polishing, and in particular to an optical lens polishing workbench. Background Technology

[0002] Grinding is a crucial process in optical lens manufacturing. When polishing optical lenses, a polishing tank is required. The polishing tank is a hemispherical structure with its opening facing upwards. A drive motor is located at the bottom, which is connected to a connecting shaft. The connecting shaft rotates and extends into the polishing tank, so the drive motor drives the connecting shaft to rotate. A clamp is connected to the upper end of the connecting shaft, and the optical lens is clamped onto the clamp for polishing. Polishing fluid is used during actual polishing, and it is collected in the polishing tank. To prevent the polishing fluid from leaking out from the connection between the connecting shaft and the polishing tank, a rotating seal structure is installed between the polishing tank and the connecting shaft. After a period of use, some impurities mixed in with the waste polishing fluid may enter the rotating seal structure, causing it to jam (during the polishing process, debris is removed and carried away by the polishing fluid, generating waste fluid into the polishing tank. A drain pipe is installed at the bottom of the polishing tank to drain the waste fluid, but some waste fluid will remain in the polishing tank for a period of time), ultimately affecting the normal polishing operation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an optical lens grinding workbench, which solves the problem that impurities in the grinding waste liquid may cause jamming and affect normal grinding operations.

[0004] According to an embodiment of this utility model, an optical lens polishing workbench includes a workbench body, which includes a horizontally arranged mounting plate. A pair of upright plates are fixedly connected to the mounting plate to make it stand on the ground. A polishing groove is also fixedly connected to the mounting plate. The polishing groove is a hemispherical structure with its opening facing upwards and a vertical cylinder is fixedly connected to the center of its bottom. A drain pipe communicating with the inside and outside of the polishing groove is also fixedly connected to the bottom of the polishing groove. The workbench also includes a connecting shaft, which is rotatably disposed inside the vertical cylinder. The lower end of the connecting shaft extends below the polishing groove, and the upper end of the connecting shaft extends above the vertical cylinder. A balancing sleeve is fixedly fitted on the upper end of the connecting shaft. The balancing sleeve is also rotatably fitted on the upper end of the vertical cylinder. A drive motor for driving the connecting shaft to rotate is installed on one of the upright plates. The solution features a vertical cylinder with its lower end fixedly connected to the grinding groove, and a connecting shaft that passes through the bottom of the grinding groove and the vertical cylinder. This moves the position of the connecting shaft's rotational sealing from the bottom of the grinding groove to the top of the vertical cylinder. A larger amount of grinding waste liquid can be filled below the top of the vertical cylinder without contacting the connecting shaft, and it also prevents impurities in the grinding waste liquid from entering the connecting shaft and the vertical cylinder and causing jamming. Therefore, it solves the problem in the prior art where impurities in the grinding waste liquid may cause jamming and affect normal grinding operations.

[0005] Furthermore, a first rotating wheel is fixedly connected to the lower end of the connecting shaft, and the drive motor has an output shaft with a second rotating wheel fixedly connected to it. The first and second rotating wheels are arranged horizontally and connected by belt drive.

[0006] Furthermore, a mounting ring is fixedly connected to the upper end of the grinding groove, and the mounting ring is fixedly connected to the upper surface of the mounting plate.

[0007] Furthermore, an annular transition section with an arc shape is provided between the lower end of the vertical cylinder and the inner bottom surface of the grinding groove, and the drain pipe is connected to the transition section.

[0008] Furthermore, a fixed sleeve is fixedly connected to the upper inner wall of the balance sleeve, and the fixed sleeve is fixedly connected to the connecting shaft. A rotating ring is fixedly connected to the vertical cylinder, and the lower rotating sleeve of the balance sleeve is located outside the rotating ring.

[0009] Furthermore, the inner ring wall of the rotating ring is recessed with multiple notches.

[0010] Furthermore, the upper ring surface of the mounting ring is higher than the grinding groove, and an inclined transition surface is provided between the two.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up a vertical cylinder fixedly connected to the grinding groove for the connecting shaft to pass through, the position of the rotating seal is raised to a higher position inside the grinding groove. This way, even if a large amount of grinding fluid is transferred into the grinding groove, it will not enter between the vertical cylinder and the connecting shaft. Therefore, it avoids impurities in the grinding fluid from entering between the vertical cylinder and the connecting shaft, and solves the problem in the prior art that impurities in the grinding waste fluid may cause jamming and affect normal grinding operations.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] In an exemplary implementation, such as Figure 1As shown, this embodiment provides an optical lens polishing workbench, which includes a workbench body. The workbench body includes a horizontally arranged mounting plate 1. The mounting plate 1 is fixedly connected to a pair of upright plates 2, which make it stand upright on the ground. A polishing groove 3 is also fixedly connected to the mounting plate 1 (the mounting plate 1 has holes for the polishing groove 3 to be installed). The polishing groove 3 is a hemispherical structure with its opening facing upwards, and a vertical cylinder 4 is fixedly connected to the center of its bottom. A drain pipe 5 connecting the inside and outside of the polishing groove 3 is also fixedly connected to the bottom of the polishing groove 3. The vertical cylinder 4 extends upwards so that its upper end is located at a higher position inside the polishing groove 3. The workbench also includes a connecting shaft 6. The connecting shaft 6 is similar to that in the prior art, and its upper end is used to connect with a clamp. The difference from the prior art is that the connecting shaft 6 rotates. The connecting shaft 6 is set inside the vertical cylinder 4, with its lower end extending below the grinding groove 3 and its upper end extending above the vertical cylinder 4. A balance sleeve 7 is also fixedly fitted on the upper end of the connecting shaft 6. The upper end of the connecting shaft 6 extends above the balance sleeve 7 for clamping. The balance sleeve 7 is also rotatably fitted on the upper end of the vertical cylinder 4. A drive motor 8 that drives the connecting shaft 6 to rotate is installed on one of the vertical plates 2. The drive motor 8 has an upwardly extending output shaft. A first rotating wheel 9 is fixedly connected to the end of the connecting shaft 6 located below the grinding groove 3. A second rotating wheel 10 is fixedly connected to the output shaft. The first rotating wheel 9 and the second rotating wheel 10 are set horizontally and are connected by a belt 11. In this way, when the drive motor 8 runs, it can drive the connecting shaft 6 to rotate. In this design, the lower end of the vertical cylinder 4 is fixedly connected to the grinding groove 3, while the connecting shaft 6 passes through the bottom of the grinding groove 3 and the vertical cylinder 4. This allows the rotating sealing position of the connecting shaft 6 to move from the bottom of the grinding groove 3 to the upper end of the vertical cylinder 4. A larger amount of grinding waste liquid can be filled below the upper end of the vertical cylinder 4 without contacting the connecting shaft 6, and it will not cause impurities in the grinding waste liquid to enter the connecting shaft 6 and the vertical cylinder 4 and directly cause jamming. Therefore, this solves the problem in the prior art where impurities in the grinding waste liquid may cause jamming and affect normal grinding operations.

[0021] like Figure 1 As shown, a mounting ring 12 is fixedly connected to the upper end of the grinding groove 3. The mounting ring 12 is fixedly connected to the upper plate surface of the mounting plate 1. That is, the upper end of the grinding groove 3 is supported on the mounting plate 1 by the mounting ring 12. Furthermore, the upper ring surface of the mounting ring 12 is higher than the grinding groove 3 and an inclined transition surface 13 is provided between the two. This allows even if there is a small amount of liquid at the upper end of the grinding groove 3, it can return to the grinding groove 3 through the transition surface 13.

[0022] like Figure 1 As shown, an annular transition section 14 with an arc transition is provided between the lower end of the vertical cylinder 4 and the inner bottom surface of the grinding groove 3. The drain pipe 5 is connected to the transition section 14, that is, the drain pipe 5 is located below the transition section 14, so that the grinding waste liquid can smoothly enter the drain pipe 5 and be discharged.

[0023] like Figure 1-3As shown, in a further embodiment, a balancing sleeve 7 is provided at the upper end of the vertical cylinder 4, which can maintain a more stable rotational connection between the upper auxiliary connecting shaft 6 and the vertical cylinder 4. More specifically, a fixing sleeve 15 is fixedly connected to the upper inner wall of the balancing sleeve 7, and the fixing sleeve 15 is fixedly connected to the connecting shaft 6. A rotating ring 16 is fixedly connected to the vertical cylinder 4, and the lower end of the balancing sleeve 7 is rotatably sleeved outside the rotating ring 16. That is, the connecting shaft 6 achieves a rotational fit with the outer wall of the vertical cylinder 4 through the balancing sleeve 7. In other words, the rotational sealing point of the two is located outside the upper end of the vertical cylinder 4. At the same time, the connecting shaft 6 and the vertical cylinder 4 can also be rotatably fitted inside the vertical cylinder 4, so that the rotational fit is more stable. The rotating ring 16 is rotatably fitted with the inner wall of the balancing sleeve 7. At the same time, multiple notches are provided in the recess of the inner ring wall of the rotating ring 16. These notches can connect the inside and outside of the balancing sleeve 7, which facilitates the replenishment of lubricant to the internal structure.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
