Grease quantifying device

Abstract

The invention relates to the related technical field of automobiles, and discloses a grease quantifying device which comprises a grease injection mechanism and a quantitative adjusting mechanism. The grease injection mechanism comprises a cavity body, a piston assembly arranged in the cavity body in a sliding mode, a hydraulic electric control valve connected with the cavity body and a cavity end cover fixed to the front end of the cavity body, the interior of the cavity body is divided into a first cavity and a second cavity by the piston, and an oil inlet and an oil outlet are formed in the cavity end cover; the quantitative adjusting mechanism comprises a bracket, a driving mechanism fixed on the bracket, a screw rod in transmission connection with the driving mechanism, a fixed sleeve in threaded connection with the screw rod, and a plunger chuck arranged in the fixed sleeve in a sliding manner, and the fixed sleeve is fixedly connected with the rear end of the cavity body; and the front end of the plunger chuck is connected with a piston rod, and the rear end of the plunger chuck abuts against the screw rod. The grease quantifying device is high in grease injection precision, low in cost, small in size, stable in output and capable of meeting the requirements of a grease injection system for quantification, high speed and controllable and adjustable grease injection range.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to a grease metering device. Background technique [0002] In the assembly process of auto parts, there are many places that need to be greased and installed, and there are strict requirements on the amount of grease added. At present, there are various methods of fat injection on the market, and there are currently two methods: manual and mechanical. The manual grease injection method is to use a quantitative spoon to add the corresponding amount to specific parts each time, and it is mainly used in parts that cannot be covered by mechanical equipment. The mechanical grease injection method is now commonly used to use compressed air as the power source or electric cylinder as the power source through the grease injection system; the air power source needs to be equipped with an independent air source device, which has a large shape and high cost The pressure output of...

Problems solved by technology

The mechanical grease injection method is now commonly used to use compressed air as the power source or electric cylinder as the power source through the grease injection system; the air power source needs to be equipped with an independent air source device, which has a large shape and high cost The pressure output of the pneumatic booster pump with viscous sealing grease is unstable due to the compressibility of the gas; the grease injection system with the electric cylinder as the power source, due to the precision limitation of the output rod of the electric cylinder or the extension rod, will lead to limited grease injection accuracy , unable to meet the requirements of quantitative high-speed grease injection system and controllable and adjustable grease injection range
