An automatic and precise assembly of an oil pump

Abstract

The invention provides an automatic accurate assembling assembly for an oil pump. The automatic accurate assembling assembly for the oil pump comprises a base, an assembling cylinder, an extrusion mechanism, a compression groove and a rotary suction mechanism. The extrusion mechanism comprises an extrusion block and an overturning assembly. The rotary suction mechanism comprises a rotary assemblyand a discharging assembly. According to the automatic accurate assembling assembly for the oil pump, the extrusion block is rotatably connected to a pushing end of the assembling cylinder, and the extrusion block can rotate to be horizontal. After one-time assembling of oil pump springs and an oil pump shell, an oil pump cylinder retracts, and the extrusion block is driven to be horizontal by theoil pump cylinder; and besides, the extrusion block is magnetized through an electromagnet, and the oil pump springs output by the discharging assembly is sucked by the extrusion block. When the assembling cylinder pushes, the extrusion block is vertically arranged and loses magnesium; the oil pump springs fall onto a bearing base accurately; the technical problem of accurate feeding of the oil pump springs is solved; horizontal placement of the oil pump springs is achieved; moreover, the oil pump springs are fed automatically; and working efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of oil pump assembly, in particular to an automatic and precise assembly assembly of an oil pump. Background technique [0002] In the prior art, the assembly of the spring in the oil pump is usually a special tool, which includes a housing seat, a pressure block and an adjusting bolt. The housing seat has a housing hole that can accommodate the spring. In the hole, the adjusting bolt is threadedly connected to the receiving seat and one end of the adjusting bolt is connected with the pressing block. When assembling the spring, first slide the pressure block to one end of the accommodation hole through the threaded connection between the adjustment bolt and the accommodation seat, then place the spring in the accommodation hole of the accommodation seat, and then tighten the adjustment bolt to make the pressure The block gradually compresses the spring until the spring is compressed enough to fit into the s...

Problems solved by technology

[0003] But, there is following problem in the mounting device of the spring in the oil pump of above-mentioned structure: one, because when spring is transferred in the spring installation groove of oil pump, accommodating seat is only placed on the housing end face of oil pump, and There is no connection structure, so it is easy for the receiving seat to slip when the spring is transferred, resulting in the phenomenon that the spring cannot be smoothly transferred to the spring installation groove on the oil pump, which in turn leads to low assembly efficiency; 2. In addition , after the spring is compressed by the pressure block, both the adjusting 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 under the reaction force of the spring As a result, the spring cannot be compressed properly 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, resulting in the spring not being able to Completely 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

[0005] However, the above-mentioned patent still has the following technical problems in the process of compressing and assembling the spring. The spring needs to be manually placed into the press-in seat, which is time-consuming and laborious. At the same time, it cannot ensure that the spring is placed horizontally in the press-in seat. , it is very easy to cause assembly failure due to placement problems
