Polishing device for engine piston insert ring machining

Abstract

The invention discloses a polishing device used for engine piston insert ring machining. The polishing device comprises a box body and two clamping mechanisms, a mounting hole is formed in the middleof the outer wall of the top of the box body, a casing pipe is inserted into the circumference inner wall of the mounting hole, a connecting rod is inserted into the circumference inner wall of the casing pipe, the circumference outer wall of the connecting rod is sleeved with an L plate, the outer wall of one side of the L plate is fixedly provided with a second electric telescopic rod through abolt, one end of an extension rod of the second electric telescopic rod is fixedly provided with a polishing machine through a bolt, and a polishing sheet is hinged to the outer wall of one side of the polishing machine. The connecting rod is rotated in the casing pipe, the polishing machine is driven to do circumference motion, the piston insert ring inner ring is polished, the polishing sheet ofthe polishing machine moves downwards, the piston insert ring outer ring is polished, and for difference sizes of piston insert rings, corresponding polishing is carried out through adjusting the length of the second electric telescopic rod.

Description

Technical field [0001] The invention relates to the technical field of polishing devices, and in particular to a polishing device for machining engine piston inserts. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. One of the components of the engine is the piston insert. The piston insert needs to be polished during the production process to ensure its smooth surface and the normal use of the piston insert and the engine. [0003] At present, most of the existing polishing devices for engine piston insert processing on the market have the following shortcomings during use: it is troublesome to polish the inner and outer rings of the piston insert. In summary, most existing engine piston inserts The polishing device for ring proce...
