Floating oil seal inner spherical surface automatic grinding and polishing machine

Abstract

This invention provides a floating oil seal inner spherical surface automatic grinding and polishing machine which can effectively improve processing efficiency of a floating oil seal inner spherical surface on the premise that processing accuracy of the floating oil seal inner spherical surface is ensured. The automatic grinding and polishing machine comprises a rack, a clamping mechanism, a feeding mechanism and a grinding mechanism, wherein the clamping mechanism and the feeding mechanism are installed on the rack, the feeding mechanism comprises two vertically arranged lead screws which are respectively provided with lead screw nuts matched with the lead screws, a movable plate is fixed between the two lead screw nuts, and the two lead screws are respectively driven by corresponding servo motors; and the grinding mechanism is installed on the movable plate and is controlled by the feeding mechanism to grind work pieces on the clamping mechanism. After quenching for the work pieces is finished, the floating oil seal inner spherical surface automatic grinding and polishing machine can be fixed on the clamping mechanism to grind, producing efficiency is greatly improved, product quality is improved, energy consumption is reduced, and production period of a floating oil seal is shortened.

Description

technical field [0001] The invention relates to the technical field of production equipment for floating oil seals, in particular to an automatic grinding and polishing machine for inner spherical surfaces of floating oil seals. Background technique [0002] The floating oil seal was born in the late 1950s and was originally used to replace the rubber oil seal on the bulldozer chassis. The original rubber oil seal was damaged very quickly due to the immersion, wear and corrosion of sediment. The floating oil seal is a compact mechanical seal device designed for such a harsh working environment. It can prevent the leakage of lubricating oil and prevent external muddy water, sand and other pollutants from invading the interior of the equipment. It has the advantages of simple structure, dirt resistance, wear resistance, vibration resistance, movement, swing and impact, reliable operation, long service life and convenient maintenance. At present, floating oil seals are widely...

Problems solved by technology

The defect of this process is: the workpiece will have a large deformation after quenching. Since the grinding process is a precision machining process, the amount of processing is small. For the deformation caused by quenching, grinding cannot be completed in a short time, resulting in a very long grinding process. , generally 4-6 hours, resulting in low production efficiency, long production cycle, waste of materials, high energy consumption, and environmental pollution
