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

Abstract

The invention relates to the technical field of automobiles, and discloses a grease quantitative device, which includes a grease injection mechanism and a quantitative adjustment mechanism. The grease injection mechanism includes a cavity body, a piston assembly slidably arranged inside the cavity body, and a hydraulic pressure connected to the cavity body. An electric control valve and a cavity end cover fixed at the front end of the cavity body, the piston divides the interior of the cavity body into a first cavity and a second cavity, and the cavity end cover is provided with an oil inlet and an oil outlet ; The quantitative adjustment mechanism includes a bracket, a drive mechanism fixed on the bracket, a screw drive connected to the drive mechanism, a fixed sleeve threadedly connected with the screw, and a plunger chuck slidably arranged in the fixed sleeve. The rear end of the cavity body is fixedly connected; the front end of the plunger chuck is connected with the piston rod, and the rear end is in contact with the screw rod. The grease injection of the invention has high precision, low cost, small volume and stable output, and can meet the requirements of a grease injection system with high quantitative speed and a controllable and adjustable range of grease injection.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a grease quantitative 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 grease injection on the market, and there are two methods: manual and mechanical. The manual grease injection method is that workers use a quantitative spoon to inject the corresponding amount to specific parts each time, mainly used in parts that cannot be covered by mechanical equipment. The general method of mechanical grease injection is 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 is large in size, high in cost, and provides high pressure and high pr...
