A fully automatic assembly process for oil pump accessories

Abstract

The invention relates to the technical field of oil pump assembling, in particular to a full-automatic oil pump accessory assembling process which comprises the following steps of loading a pump body,enabling the pump body to be in butt joint, compressing a spring, centering the spring, and pushing and resetting the spring, wherein during the spring compressing step and the spring centering step,the spring is compressed to the preset length and is centered with a spring installation slot; during the spring compressing step, two ends of the spring are carried by carrying seats, so that the spring is prevented from being bent and inclined due to compression; and in addition, after the spring is installed, during the pushing air cylinder resetting process, the next spring is automatically fed. The technical problem that the spring cannot be accurately and high-efficiently assembled o the oil pump is solved, the levelness of the spring is ensured during the installation process, and theassembling error caused by the inclining and the bending of the spring is avoided.

Description

technical field [0001] The invention relates to the technical field of oil pump assembly, in particular to a fully automatic assembly process for oil pump accessories. Background technique [0002] When the automobile engine is working, each moving part acts on another part with a certain force, and high-speed relative motion occurs. With relative motion, friction will inevitably occur on the surface of the parts, thereby accelerating wear. Therefore, in order to reduce wear and tear, reduce friction resistance and prolong service life, there must be lubrication system parts on the engine. The main components of the lubrication system are various equipment such as an oil pump. The function of the oil pump is to increase the oil to a certain pressure and then forcefully send it to the moving surface of each part of the engine. It generally includes a pump cover and a pump body. It is connected with the pump body by screws, and the pump body is equipped with an inner rotor, a...

Problems solved by technology

[0005] 1) Since when the spring is transferred to the spring installation groove of the oil pump, the receiving seat is only placed on the end face of the oil pump housing without any connection structure, so it is easy to remove the receiving seat when the spring is transferred. The phenomenon of slipping occurs, which causes the spring to not be smoothly transferred to the spring installation groove on the oil pump, which in turn leads to low assembly efficiency;

[0006] 2) In addition, after the spring is compressed by the pressure block, both the adjustment bolt and the pressure block are subjected to the reaction force of the spring, and when the spring is knocked into the spring installation groove on the oil pump, the vibration generated by the knock will make the adjustment bolt in the spring Under the action of the reaction force, the receiving seat is unscrewed, so that the spring is not compressed enough before it enters the spring installation groove on the oil pump. In other words, the compression of the spring does not reach the preset length. As a result, the spring cannot fully enter the spring installation groove of the oil pump, and the adjusting bolt has to be screwed in again until the compression of the spring reaches the preset span, which affects the assembly efficiency

[0009] 1. The spring still needs to be manually placed in the compression groove by the worker, but the space between the compression groove and the pressing block is narrow, and the manual placement of the spring is difficult and the accuracy is low;

[0010] 2. The two ends of the spring are not supported or limited. Due to the uneven force applied during the extrusion process, it is easy to cause the spring to tilt during the compression process. As a result, when the spring is pressed into the spring installation groove, due to the spring tilt , causing the spring to pop out of the spring mounting groove, and the installation fails
