In the production process flow of the ceramic dielectric filter, the frequency modulation test is one of the most time-consuming and labor-consuming processes, and becomes a bottleneck influencing the production performance of the dielectric filter. One method for solving the bottleneck problem is to replace manpower with a robot, and polish and remove a plating layer on the surface of the ceramic dielectric filter through a high-speed electric spindle clamping diamond grinder so as to realize automatic frequency modulation test. Because the ceramic surface has higher hardness, the robot needs to have certain floating when clamping the grinding pin and grinding, otherwise the grinding pin is easy to break. Therefore, a floating mechanism is needed to avoid breaking of the grinding pin to ensure continuity of the automated frequency modulation test.
The existing floating flexible polishing mechanisms in the market are mainly divided into two types, namely an axial floating polishing mechanism and a radial floating polishing mechanism. The frequency modulation test of the ceramic dielectric filter is to polish the bottom or the side wall of a small cylindrical hole on a product of the ceramic dielectric filter, and the ceramic dielectric filter needs to have the axial and radial floating functions; and the grinding pin is allowed to bear small floating force, and the magnitude of the floating force needs to be subjected to fine adjustment control.
