Abstract

Uniformly process by circumferencial direction that there are three charge levels under the spiral mutually disconnected the utility model discloses a kind of pump body chamfering step processing gang tool, including cutter hub, cutter head, on cutter head;There are two step knife faces for the top processing of charge level under each spiral, are ramped shaped chamfering knife face between two step knife faces of charge level under each spiral;Charge level under each spiral it is upper under step knife face above and spiral at the top of charge level between be also machined with ramped shaped chamfering knife face.The utility model avoids bring precision problem due to repeatedly replacing cutter and generates, and also improves working efficiency.

Description

Gang tool is used in a kind of processing of pump body chamfering step
Technical field
The utility model relates to a kind of pump body chamfering step processing gang tools, belong to oil pump machining apparatus neck Domain.
Background technique
The main supporting body of oil pump is exactly the pump housing, in pump housing machining, specifically to the pump housing plunger hole bored When top surface processes, two kinds of cutters are at least needed: another one is for processing two steps to the plunger hole top surface bored It is for carrying out chamfering to step.The use of much knives tool needs in process repeatedly replacement, and processing efficiency is to be improved, And be easy to produce because of machining accuracy problem brought by replacement cutter, in addition, existing gang tool structure is not compact, and adding Working hour, clast are not easy to fall from processing place, influence machining accuracy, are not suitable for the processing of fuel feed pump plunger hole top surface.
Summary of the invention
In view of the deficiency of the prior art, the purpose of the utility model is to provide a kind of design of structure is more reasonable Pump body chamfering step processing use gang tool.
Pump body chamfering step processing combination that in order to achieve the above purposes, the technical solution adopted by the utility model is: Cutter, including cutter hub, cutter head, which is characterized in that uniformly process by circumferencial direction that there are three under the spiral mutually disconnected on cutter head Charge level, one side opposite with charge level under adjoining spiral on charge level is inclined-plane under each spiral, the outside of charge level under each spiral Spiral reinforcing rod is machined on face;There are two step knife faces for the top processing of charge level under each spiral, under each spiral It is ramped shaped chamfering knife face between two step knife faces of charge level;Charge level is upper in step knife above under each spiral Ramped shaped chamfering knife face is also machined between charge level top under face and spiral.
Compared with prior art, the beneficial effect that the utility model has is: 1, by by step knife face, chamfering knife face Deng design on a knife, avoids bring precision problem due to repeatedly replacing cutter and generate, and also improve work effect Rate;2, charge level side is designed to inclined-plane under spiral, and convenient in processing, clast caused by cutting can be discharged in time without influencing knife Matching between head and workpiece to be added, ensure that machining accuracy;3, the spiral reinforcing rod setting under spiral on charge level, ensure that knife The intensity of head.In addition, also reducing processing cost.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
Presently in connection with attached drawing, the utility model is further described.Obviously, therefore the utility model cannot be limited in Among the embodiment described range.Based on the embodiments of the present invention, those of ordinary skill in the art are not making wound Every other embodiment obtained under the premise of the property made is worked, is within the scope of protection of the invention.It should be noted that When building block is referred to as " being machined with " another component, the two be can be by the usual manners connection such as being integrally formed, welding It forms.Term used in this specification " left side ", " right side ", "front", "rear" and similar expression for illustrative purposes only, Model, size, condition are not specified in following embodiments, conventionally, or selects according to product manual.
As shown in Figure 1, pump body chamfering step, which is processed, uses gang tool, including cutter hub 1, cutter head 2, by circle on cutter head 2 Circumferential direction is uniformly processed there are three charge level 2.1 under the spiral that mutually disconnects, under each spiral on charge level 2.1 with adjoining spiral blanking The opposite one side in face 2.1 is inclined-plane 2.11, is machined with spiral reinforcing rod 2.12 on the lateral surface of charge level 2.1 under each spiral, 2.12 lower end of spiral reinforcing rod extends on cutter hub 1;There are two step knife faces for the top processing of charge level 2.1 under each spiral 2.2, it is ramped shaped chamfering knife face 2.3 between two step knife faces 2.2 of charge level 2.1 under each spiral;In each spiral On lower charge level 2.1 step knife face 2.2 located above be also machined with ramped shaped between the top of charge level 2.1 under corresponding spiral Chamfering knife face 2.3.
When processing, the utility model cutter head is directed at downwards pump housing plunger hole upper surface, the pump housing is put upside down, high speed rotation knife Head, step knife face processes two adjacent steps, while rose reamer carries out chamfering on the inside of step, processes the broken of generation Bits are discharged from inclined-plane in time.
