Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to internal burr grinding equipment for lens barrel processing. Background Art

[0002] Burrs refer to the residual chips and fine particles generated on the surface of components after production due to cutting, demolding, cutting, etc. These burrs are noticeable to the touch and will interfere with the installation of other components, resulting in reduced installation accuracy.

[0003] After the production of existing lens barrels, the inner surface of the barrel will have residual flash and fine particles, collectively known as burrs, due to various factors. In order to remove these burrs, the inner wall of the lens barrel needs to be polished and ground to reduce the impact of the burrs on the components. The existing polishing method directly inserts a cylindrical polishing rod into the interior of the lens barrel for polishing. The size of the polishing rod is often fixed and cannot be adjusted according to needs. When polishing lens barrels of different sizes, a large number of polishing rods of different sizes are required, which is very costly.

[0004] Therefore, we propose an internal burr grinding device for lens barrel processing. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an internal burr grinding device for lens barrel processing, comprising a motor, the output end of the motor is fixedly connected to a turntable, the outer surface of the upper end of the turntable is provided with three groups of supporting plates, the supporting plates are designed as an arc-shaped structure, and a woven grinding layer is attached to the arc-shaped outer surface.

[0007] The outer surface of the upper end of the supporting plate is fixedly connected with a guide rod with an inclined structure, and the supporting plate and the guide rod are in three groups.

[0008] Among them, a slider with a T-shaped structure is fixedly connected to the outer surface of the lower end of the supporting plate, and a sliding groove matching the slider is opened at the corresponding positions of the turntable and the slider. The slider is located inside the sliding groove, and a spring is fixedly connected between the two.

[0009] Among them, a connecting rod is fixedly connected to the center position of the outer surface of the upper end of the turntable, and the connecting rod has an annular outer surface with an adjustment ring sleeved on it. The annular outer surface of the adjustment ring is rotatably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the adjustment ring is rotatably connected to the support plate.

[0010] The spring is located inside the sliding slot near one end of the connecting rod.

[0011] Wherein, a guide groove is provided on the annular outer surface of the connecting rod, and a guide block is fixedly connected to the corresponding position of the adjusting ring and the guide groove.

[0012] Wherein, a thread groove is provided on the annular outer surface of the connecting rod, and a pressing sleeve is threadedly connected to the surface.

[0013] The utility model has at least the following beneficial effects:

[0014] By arranging multiple groups of supporting plates with arc-shaped structures on the surface of the turntable, which are driven by a motor, the lens barrel is put on the surface of the supporting plates to polish and grind the inner wall of the lens barrel. By arranging an inclined guide rod, the user can directly align the lens barrel with the guide rod and squeeze it downward, so that the supporting plates move inward and make the outer wall fit the inner wall of the lens barrel. The above structure can polish and grind lens barrels with different inner diameters, thereby improving versatility and reducing usage costs. BRIEF DESCRIPTION OF THE DRAWINGS
