Heat insulation sleeve pressing mechanism of heat insulation piston pin of air compressor

Abstract

The invention discloses a heat insulation sleeve pressing mechanism of the heat insulation piston pin of an air compressor. The heat insulation sleeve pressing mechanism comprises a fixing bottom plate, a lower fixing block is fixed to the top face of the middle of the fixing bottom plate, a lower clamping block is fixed to the top face of the lower fixing block, a lower arc-shaped groove is formed in the top face of the lower clamping block, a rear supporting plate is fixed to the top face of the fixing bottom plate behind the lower fixing block, an upper horizontal plate is fixed to the topface of the rear supporting plate, an upper pressing air cylinder is fixed to the top face of the upper horizontal plate, a push rod of the upper pressing air cylinder penetrates through the bottom face of the upper horizontal plate and is fixedly provided with an upper pressing plate, an upper clamping block is fixed to the bottom face of the upper pressing plate, an upper arc-shaped groove is formed in the bottom face of the upper clamping block, a to-be-installed pin shaft is located between the upper arc-shaped groove and the lower arc-shaped groove, and heat insulation sleeves are clampedat the end parts, connected with the shaft parts, of the two ends of the pin shaft. According to the heat insulation sleeve pressing mechanism of the heat insulation piston pin of the air compressor,the heat insulation sleeves can be automatically and completely pressed into the connecting shaft parts at the two ends of the pin shaft, so that the heat insulation sleeves are stressed uniformly, and the installing effect is good.

Description

technical field [0001] The invention relates to the technical field of air compressor equipment manufacturing, and more specifically relates to a heat insulating sleeve pressing mechanism of a heat insulating piston pin of an air compressor. Background technique [0002] In the existing piston-type air compressor, a piston is installed in the cylinder body, and a piston pin needs to be installed between the piston and the connecting rod for connection, and the piston pin conducts heat, transferring the heat of the piston to the roller on the connecting rod. The needle bearing affects its service life, so a heat insulation sleeve is designed to fix the two ends of the piston pin to reduce heat conduction; [0003] The existing method is to manually put the heat insulation sleeve on the connecting shaft at the end of the piston pin, and then push it down manually. It is easy to be damaged and affects the installation effect. Contents of the invention [0004] The purpose o...
