Technical field

The present invention relates to lubricating oil pump mounting technology fields, especially a kind of to be convenient for mounted elastically lubricating oil pump.

Background technique

In the assembling process of lubricating oil pump, need pump cover and the pump housing carrying out installation connection, due to lubricating oil pump it is generally necessary to Safety valve, control valve or pressure limiting valve are set, are typically provided with plunger, spring and blocking, in valve opening in order to optimize machine oil The structure of pump, certain designs can make pump cover directly play the role of blocking, specifically, one end of spring can be made to resist column Plug, the other end lie directly against pump cover then to realize the function of pressure limiting valve, block this components to save, reduce the life of product It produces cost, while improving machining accuracy (blocking bring dimensional tolerance problem is bigger).

The lubricating oil pump of above structure often suffers a problem that during assembly, is installed on the pump housing in its pump cover Before, it is necessary first to spring is placed in the mounting hole of the pump housing, and a part of spring can be stretched out from mounting hole, extension For the height of the spring divided much higher than the height of the positioning pin on pump housing mounting surface, this makes pump cover when being installed on the pump housing, pump The mounting surface of lid can first encounter spring, and since spring has elasticity, when stress easily shakes and deflection, this makes determining for pump cover The positioning pin of position hole and the pump housing increases difficulty during being assembled together, and assembly in this way not only reduces production efficiency, Also increase worker labour.

Summary of the invention

Problem to be solved by this invention is to provide one kind convenient for mounted elastically lubricating oil pump, can be used tooling first by bullet The height of spring is forced down, and further takes out tooling after having good positioning to pump cover and pump housing assembly, and spring can be under own resilient effect at this time So that one end is resisted pump cover, so that the assembly work of lubricating oil pump be rapidly completed, improves production efficiency, reduce labour.

In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of be convenient for mounted elastically lubricating oil pump, Including the pump housing and pump cover, the mounting surface of the pump cover is equipped with the limit hole for being packed into spring, opens on the side wall of the pump housing Equipped with the through-hole for being connected to mounting hole, correspondence offers slot on the inner wall of the mounting hole, by the way that spring is pressed into mounting hole It is interior, tooling can be made to pass through through-hole and be inserted into slot to which limited spring stretches out mounting hole.

Preferably, the mounting surface of the pump housing is equipped with the mounting hole for placing spring.

Preferably, the height of the slot and the height of through-hole are corresponding consistent.

It is highly preferred that the through-hole is strip-shaped hole, the slot is strip groove.

It is highly preferred that the length of the strip-shaped hole is less than the diameter in inner wall of the hole installing face.

The present invention also provides another kinds to be convenient for mounted elastically lubricating oil pump comprising the pump housing and pump cover, the peace of the pump housing Dress face is equipped with the mounting hole for placing spring, and the side of the pump cover, which offers, to be lacked for tooling by what is be caught in inside outside Mouthful, the notch is corresponding with the position of mounting hole, and the width of the notch is less than the diameter of spring.

Preferably, the mounting surface of the pump cover is equipped with the limit hole for being packed into spring, and the notch is connected to limit hole.

Preferably, the length of the notch is greater than the diameter of limit hole.

It is highly preferred that the notch is strip notch.

The beneficial effects of the present invention are: for the first above-mentioned scheme, before pump cover is installed on the pump housing, Spring is placed in mounting hole, and the top of spring is stretched out outward, can be used casting die tooling that the top of spring is pressed into installation at this time Kong Zhong, and the top of spring is made to be located at the lower section of through-hole and slot, it reuses positive stop strip tooling and is penetrated from through-hole and be inserted into slot In, after withdrawing from casting die tooling, spring can withstand positive stop strip tooling upwards, to be restricted and can not stretch out outward, at this time will Pump cover is assembled on the pump housing, and the location hole of pump cover and the positioning pin of the pump housing can quickly form cooperation, and pump cover is connect with the pump housing After good, positive stop strip tooling is pulled, spring makes its top resist the mounting surface of pump cover to complete to fill under own resilient effect Match.

For above-mentioned second scheme, it can first be caught in positive stop strip tooling in the notch of pump cover, make positive stop strip tooling Bottom end stretch out notch down, in this way when pump cover is toward when installing on the pump housing, positive stop strip tooling can touch spring and first by bullet Spring compression makes height of the tip height of spring lower than the positioning pin of pump housing mounting surface or is substantially flush with pump housing mounting surface, Just first the location hole of the positioning pin of the pump housing and pump cover can be assembled in this way, then pulled positive stop strip tooling outward, spring exists Its top is set to resist the mounting surface of pump cover to complete to assemble under own resilient effect.

For existing installation method, the lubricating oil pump of the structure can be obviously shortened the assembly time of pump housing pump cover, mention High efficiency reduces labour.
