Description

Technical Field

[0001] The utility model relates to the field of grinding devices, in particular to a high-precision surface grinding device for processing a coaxial connector shell. Background Art

[0002] At present, a Chinese utility model with announcement number CN218397479U discloses a high-precision surface grinding device for processing a coaxial connector shell, comprising: a movable plate, a movable groove is arranged inside the movable plate; a cylinder, the cylinder is located inside the movable groove, the upper end of the cylinder is fixedly connected to a push plate, a limit rod is arranged inside the push plate, and a rack is fixed at one end of the push plate; a clamping block, the clamping block is located at one end of the movable plate, a rotating rod is arranged inside one end of the clamping block, the inner end of the rotating rod is movably connected to a first extrusion block, the outer end of the rotating rod is fixedly connected to the rotating block, and a transmission rod is movably arranged at one end of the clamping block, the inner end of the transmission rod is fixedly connected to the second extrusion block, and the outer end of the transmission rod is fixedly connected to a transmission wheel; the beneficial effect is that the cylinder in the high-precision surface grinding device for processing a coaxial connector shell proposed in the utility model cooperates with the rack, which can drive the transmission wheel to rotate, so that the coaxial connector shell can rotate during grinding.

[0003] Although the existing grinding device can make the connector shell rotate during grinding through the driving component, there are still other problems in actual use, such as the poor fixing effect of the grinding belt. The grinding belt is a consumable and needs to be clamped at both ends when in use. Although the torsion spring clamping method is convenient, it is easy to shift and fall when it is affected, and it does not have dust collection and filtration function. The coaxial connector shell is a metal product, and powder will be generated during grinding. The powder with lower density will be lifted and dispersed with the air. If it is accidentally inhaled by people, it will cause damage to the respiratory tract. The practicality is low. In order to solve the above-mentioned problems, we propose a high-precision surface grinding device for coaxial connector shell processing. Utility Model Content
