Description

Technical Field

[0001] The utility model relates to the technical field of lens barrel processing, in particular to a fixing device for processing an optical instrument lens barrel. Background Art

[0002] ‌The optical lens barrel is an important component for supporting and protecting the internal components of the optical lens.‌ It is usually made of metal or alloy and has a thin-walled cylindrical structure.‌ During the processing of the optical lens barrel, if the position of the lens barrel is unstable, it will lead to rough processing and affect the optical performance of the final product. By fixing the lens barrel, the assembly quality of the lens barrel after processing can be ensured.

[0003] For example, a clamping device for lens barrel processing with the publication number of CN219987265U disclosed in the Chinese patent. By placing the left clamping block and the right clamping block on the lifting table, the left clamping block and the right clamping block can clamp and fix the lens barrel. And the lifting table is placed in the embedding groove, and an inclined slider is arranged below the embedding groove. The inclined slider is threadedly connected with the threaded rod. When the threaded rod is rotated, the inclined slider will move, thereby pushing the lifting table to move up and down, thus realizing the fine adjustment of the height of the lens barrel, so that during the processing of the lens barrel, only the height of the lifting table needs to be adjusted and there is no need to adjust the processing tool anymore, reducing the processing difficulty.

[0004] When the above clamping device is actually used, the lens barrel is clamped by the left clamping block and the right clamping block. When holes need to be drilled on the outer walls at both ends of the lens barrel, the left clamping block and the right clamping block form an obstruction and do not completely expose the outer wall of the lens barrel. And there is no limit mechanism during height adjustment, resulting in the lens barrel being able to move upward and the overall being unstable. Content of the Utility Model

The operation of the motor 2 drives the frame 3 to rotate.

[0024] One end of the output shaft of the motor 2 is fixedly connected to the frame 3. An electric push rod 4 is fixedly connected to the inside of the frame 3. The top of the output end of the electric push rod 4 is fixedly connected to a U-shaped frame 5. The electric push rod 4 drives the U-shaped frame 5 to lift. Two guide rods 6 are fixedly connected to the outer wall of the U-shaped frame 5. Two moving plates 8 are slidably sleeved on the outer walls of the two guide rods 6. Two sliding holes are opened on the outer wall of the moving plate 8. The inner walls of the two sliding holes are respectively slidably connected to the outer walls of the two guide rods 6. The two moving plates 8 slide through the two guide rods 6.

[0025] The outer wall of the U-shaped frame 5 is fixedly connected with a back-to-back cylinder 7. The two output ends of the back-to-back cylinder 7 are connected through a three-way joint between the pipelines. The outer walls of the two output ends of the back-to-back cylinder 7 are respectively fixedly connected with the outer walls of two moving plates 8. The tops of the two moving plates 8 are both fixedly connected with docking sleeves 9.

[0026] A pushing mechanism is arranged inside the docking sleeve 9. The pushing mechanism includes a bolt 13. A threaded hole is opened on the outer wall of the docking sleeve 9. The inner wall of the threaded hole is threadedly connected with the outer wall of the bolt 13. One end of the bolt 13 is rotatably connected with a double-cone column 11 through an existing bearing. A bearing is fixedly sleeved on the outer wall of the bolt 13. The outer ring of the bearing is fixedly connected with the outer wall of the double-cone column 11. The outer wall of the double-cone column 11 is slidably connected with the outer wall of a sliding extrusion block 10. A plurality of mounting holes 14 are opened on the outer wall of the T-shaped frame 1.

[0027] An expansion mechanism is arranged on the outer wall of the docking sleeve 9. The expansion mechanism includes a plurality of sliding extrusion blocks 10. A plurality of rectangular grooves are evenly opened on the outer walls of the two docking sleeves 9. The inner walls of the plurality of rectangular grooves are respectively slidably connected with the outer walls of the plurality of sliding extrusion blocks 10. The contact surface between the sliding extrusion block 10 and the double-cone column 11 is an inclined surface.

Rotate the corresponding two bolts 13 to drive the double-cone column 11 to move in the docking sleeve 9. When the double-cone column 11 continuously presses on the outer walls of the plurality of sliding extrusion blocks 10, the plurality of sliding extrusion blocks 10 expand outwards through their own inclined surfaces. The plurality of sliding extrusion blocks 10 press on the inner wall of the lens barrel to form an inner support effect to fix the position of the lens barrel. During the expansion process, the elastic rubber rings 12 are elastically expanded. Subsequently, when the double-cone column 11 no longer presses, the elastic force drives the plurality of sliding extrusion blocks 10 to reset along the rectangular grooves. The motor 2 operates to rotate the frame 3. The rotation of the frame 3 drives the electric push rod 4 and the U-shaped frame 5 to rotate to adjust the rotation of the lens barrel. The electric push rod 4 operates to drive the U-shaped frame 5 to lift. The lifting of the U-shaped frame 5 drives the lens barrel to lift, changing the position of the lens barrel during processing and improving applicability.
