Technical field

It is especially a kind of for being evenly distributed with drilling jig in the circumferential direction of revolution body cone the present invention relates to a kind of drill jig.

Background technique

Using drill jig, cooperating drilling machine drilling is the most important processing method of machinery industry.On many revolving parts, warp Be commonly present some such circular holes: they are present on the conical surface, are evenly distributed in the circumferential, and the axis and revolving body in hole The bus of part is vertical.For this pores, due to that the axis in hole can not be made in a vertical state by the method for simple rotation, because This method that must take special process equipment or hand drill could complete the processing in hole, and there are processing cost height, hole table The disadvantage that face surface quality is poor, production efficiency is low.Therefore, there is an urgent need to a kind of drill jigs passes through letter under the cooperation of common driller Single operation, can be realized the requirement of the circumferential cloth hole of low cost, such conical surface of highly-efficient processing, and meet the need of mass production It wants.

Currently, there are two kinds for the basic processing method of the circumferential cloth hole of revolution body cone.One is use special fixture to incite somebody to action The cylindrical body part of revolving parts clamps, and disposably carries out the porose processing of institute using five expensive axis equipment.It is another It is to be fixed on revolving parts on simple drill jig；Combination body is clamped with rotatable chuck, holds hand drill Add first hole out；Then continuous rotary chuck successively processes second hole, third and the 4th etc..

Major defect is:

1, hole is processed using five axis equipment, although not needing special fixture, since five axis equipment prices are extremely expensive, Processing charges is high；Additionally need programming, it is desirable that worker has higher quality.

2, match the processing method of hand drill using simple drill jig, there are the technology water that hole surface quality is limited by operator Flat disadvantage.

3, there is the shortcomings that processing efficiency is low and is not suitable for mass production in above two method.

Summary of the invention

The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of drill jig, it is circumferential that revolution body cone may be implemented The processing of equal cloth hole.

In order to achieve the above object, present invention employs following technical proposals:

A kind of drill jig, including support base, hollow bushing；The support base two sides are provided with perforative revolving body cavity, empty Cavity axis is horizontal by angle；Revolution body component is inlayed in cavity；The bushing is rotary structure, is socketed in bearing On diameter；Bushing left side is provided with several uniformly distributed location holes；Bushing right end is hollow circular cone structure, and conical surface level is set It sets；It is provided with several uniformly distributed holes in conical surface circumferential direction, has drill bushing in hole, secure component is set by any hole；On the conical surface The hole of cloth and the hole location of location hole correspond；Support base and any location hole hole location corresponding section are provided with second location hole； Bushing left side is fixed with Internal baffle.

Drill jig using the above structure, bushing the axis of revolving body cavity can rotate in support base.It will need to punch Revolution body cone part be put into from bushing left end, tighten Internal baffle.Rotary liner, when being provided with fastening on the bushing conical surface by hole The drill bushing of component vertically upward when, the first positioning pin is sequentially inserted into second location hole, location hole, is able to rotate bushing not, this When the drill bushing axis will vertically upward.

The a whole set of drill jig installed is placed on the workbench of upright drill, adjusts the position of drill jig in the horizontal plane, when When the central axis coaxial of the axis of drill bushing vertically upward and drill bit, drill jig and drilling machine are assembled together.

Start drilling machine, after first hole is processed on the revolving parts conical surface, is immediately inserted into the second positioning pin, second is fixed First hole that position pin has processed bushing and product fixes, then tightens secure component, and the second positioning pin is compressed, is kept away Exempt from product in bushing internal shift.It takes out the first positioning slightly, rotates Internal baffle, bushing rotation is driven, when next positioning of bushing Hole is aligned with second location hole, again insertable into the first positioning pin, then starts lathe, is processed on revolving parts next Hole.This step is repeated, the porose processing of institute can be completed.

Drilling Jig Structure of the present invention is simple, can be manufactured using simple machining equipment, manufacturing cost is low.Operating process ten It is point simple, drilling time is short, high production efficiency, processing metapore surface quality is high, does not have particular/special requirement to worker.Using common The processing in hole can be completed in upright drill, does not need expensive numerical control device, and cost of goods manufactured is low, is suitble to the mass of product Production.

It is preferred that drill jig further includes mandrel, the bushing is socketed in rotation by mandrel close to conical surface outer peripheral surface On component.Bushing fixes stronger with rotary part.

It is preferred that the rotary part is bearing, bushing is socketed on bearing inner race.

It is preferred that revolving body cavity and bushing are coaxial.When ensuring rotary liner, drill bushing axially can be vertically upward.

It is preferred that cavity axis angle with horizontal plane is 15 °, frustum of a cone cone element and axis are in 15 °.

It is preferred that the bushing left side setting is fluted, the boss of Internal baffle and the groove gap of bushing are matched It closes.It fixes stronger.Second location hole corresponding with the location hole is arranged on Internal baffle.

It is preferred that further including being connected in the outer ring baffle for fixing lower rotary part on the left of cavity.
