Description

Technical Field

[0001] The utility model belongs to the technical field of clamps and relates to a capacitor rubber clamp, in particular to a capacitor rubber polishing clamp. Background Art

[0002] Capacitor rubber is usually made of high-performance insulating materials such as silicone rubber, ethylene propylene rubber, butyl rubber, etc. These materials have good insulation properties, high temperature resistance and aging resistance, which can ensure that the capacitor maintains stable electrical performance during long-term use.

[0003] Polishing can remove the oxide film and other impurities on the capacitor rubber surface, thereby improving the adhesion performance of the metal or other material surface. This is crucial for capacitors because good adhesion ensures that the various components inside the capacitor are tightly combined, thereby improving its overall performance and reliability.

[0004] During traditional polishing, the rubber is fixed to a ring fixture. Impurities and foreign matter generated by water-abrasive polishing will enter through the mounting holes on the rubber, causing foreign matter to get stuck during subsequent installation of the rubber, resulting in installation gaps. Long-term use can easily cause aging and damage, so it is necessary to improve the mounting fixture to reduce foreign matter in the mounting holes. Summary of the Invention

[0005] The purpose of the utility model is to provide a capacitor rubber polishing fixture which is foreign body-proof and easy to clean in order to solve the above problems in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a capacitor rubber polishing fixture, characterized in that it includes a fixture base, the fixture base is provided with a rubber plug that is engaged with the fixture base, and the rubber plug is provided with a plurality of wire mounting holes, the fixture base is provided with a guide column corresponding to the wire mounting hole, the top of the guide column is provided with a mounting cavity, the mounting cavity is provided with a support spring, and the top of the support spring is provided with a rolling ball, the end of the mounting cavity is provided with an inwardly inclined water collecting funnel, and a protruding blocking gear ring is provided on the water collecting funnel.

[0007] In the above capacitor rubber polishing fixture, drainage holes communicating with the mounting cavity are provided in the guide columns, and water collection holes communicating with a plurality of drainage holes are provided on the fixture base.

[0008] In the above capacitor rubber polishing fixture, a downwardly extending horn hole is provided in the wire installation hole, a protruding limiting boss is provided on the guide column, and a trapezoidal spring is provided on the limiting boss.

[0009] In the above capacitor rubber polishing fixture, an open groove is provided on the side wall of the fixture base, a convex ring is provided on the side wall of the rubber plug, and the bottom of the convex ring is in conflict with the fixture base.

[0010] In the above-mentioned capacitor rubber polishing fixture, a transmission unit is provided at the bottom of the fixture base, a mounting rod is provided at the end of the transmission unit, a stripping hook is provided on the mounting rod, and a CNC water grinding device is provided on one side of the transmission unit.

[0011] Compared with the existing technology, this capacitor rubber polishing fixture uses a guide column to position and install the rubber plug for grinding, reducing surface twisting during grinding and increasing surface smoothness. By collecting and removing water and foreign matter, foreign matter inside the rubber plug is reduced, thereby increasing the qualified rate of the capacitor after installation. The open groove facilitates the disassembly and assembly of the rubber plug, and can cooperate with the stripping hook to conveniently disassemble the rubber plug after processing, reducing manual operation and increasing work efficiency. The trapezoidal spring lifts the rubber plug upward after the grinding process is completed, which can reduce the difficulty of disassembly during unloading. BRIEF DESCRIPTION OF THE DRAWINGS
