Abstract
The utility model discloses a kind of more eccentric shaft centre bore classification processing drilling jig tool, the drilling jig tool includes a bushing plate with multiple drill jig holes, there are on the positioning reference plane of the bushing plate at least two location-plates for extending forward, angle between the center line of adjacent positioned plate is less than 180 °, and the locating surface of each location-plate is planar structure.This utility model forms two location-plates that face contact with more eccentric shaft outer wall plane by arranging on bushing plate, ensure that the accuracy of drill jig positioning, realize each drill jig hole and the accurate corresponding center hole machined of each shaft part on bushing plate, rule of operation, safe and reliable is not only conformed with by processing of the drilling jig tool to multi-eccentric centre bore, realize the classification processing of centre bore in processing technique, and ensure that crudy, simple structure, easy to use.
Description
Technical field
This utility model is related to the drill jig field in machining, and specifically a kind of more eccentric shaft centre bore classification processing is bored
Die craft equipment.
Background technology
Eccentric shaft is the core part on gearing, therefore the crudy of eccentric shaft part directly affects gearing
Normal operation and service life.
In the processing of axial workpiece, its centre bore is the positioning datum for processing clamping in operation；Due to more eccentric shaft class
Part has multiple shaft parts, and the centre bore of each shaft part is not on same position, more so as to define in the clamping end face of workpiece
Individual intensive arrangement positioning datum again together, the positioning datum of this multiple intensive arrangements can be produced in the processing of more eccentric shaft again
Interfere, so as to affect being smoothed out for center processing, maloperation is caused to crudy easily, do not meet safety operation rule
Journey.
The content of the invention
Goal of the invention of the present utility model is：For above-mentioned the deficiencies in the prior art, there is provided one kind meet rule of operation,
More eccentric shaft centre bore classification processing drilling jig tool that is safe and reliable, avoiding generation mismachining tolerance, ensure crudy.
The technical scheme adopted by this utility model is：A kind of more eccentric shaft centre bore classification processing drilling jig tool, it is described
Drilling jig tool include one have multiple drill jig holes bushing plate, on the positioning reference plane of the bushing plate have extend forward to
Few two location-plates, the angle between the center line of adjacent positioned plate are less than 180 °, and the locating surface of each location-plate is planar structure.
Further, drill jig sleeve is axially equipped with the drill jig hole.
Further, the drill jig sleeve and drill jig hole are elastic conjunction.
Further, the location-plate on the bushing plate is two pieces.
Further, the angle on the bushing plate between the center line of adjacent positioned plate is 90 °.
The beneficial effects of the utility model are：This utility model is by arranging and more eccentric shaft outer wall plane on bushing plate
Two location-plates of formation face contact, it is ensured that the accuracy of drill jig positioning, realize each drill jig hole and each axle on bushing plate
The accurate corresponding center hole machined of section, not only conforms with rule of operation, peace by processing of the drilling jig tool to multi-eccentric centre bore
It is complete reliable, realize the classification processing of centre bore in processing technique, and ensure that crudy, simple structure, easy to use.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Code name implication in figure：1-location-plate；2-screw；3-bushing plate；4-drill jig hole；5-drill jig sleeve.
Specific embodiment
Processing drilling jig tool of this utility model for more eccentric shaft clamping centre bore, which is according to the different shaft part of more eccentric shaft
Cover half processes corresponding centre bore.The clamping end of the more eccentric shaft involved by this utility model has two planes, the two
Angle between the center line of plane should be less than 180 °, and in the present embodiment, the angle between the center line of the two planes is preferred
90°。
Referring to Fig. 1 and Fig. 2：This utility model includes bushing plate 3 and two location-plates 1.
Wherein, bushing plate 3 is platy structure, with the positioning reference plane fitted with more eccentric shaft clamping end.In drill jig
Offered according to the shaft part of more eccentric shaft on plate 3 and multiple meet design requirement, theoretical position drill jig hole 4, i.e. bushing plate 3
On each drill jig hole 4 should correspond to the axle center of one section of shaft part on more eccentric shaft；Each drill jig hole be through-hole structure, each drill jig
Drill jig sleeve 5 is axially equipped with elastic conjunction mode in hole 4.
Two location-plates 1 are platy structure, and they have smooth positioning plane respectively.Two location-plate intervals are fixed
In the periphery of bushing plate, extend from the positioning reference plane of bushing plate；Position of the two location-plates on bushing plate should
Corresponding with two planes of more eccentric shaft clamping end, i.e., the angle between two 1 center lines of location-plate is 90 °, so as at this
When utility model is applied to the clamping end of more eccentric shaft, two location-plates are able to and two locating surfaces on more eccentric shaft
Form corresponding face contact.
Above-mentioned concrete technical scheme only to illustrate this utility model, rather than a limitation.Although with reference to above-mentioned concrete skill
Art scheme has been described in detail to this utility model, it will be understood by those within the art that：Which still can be right
Above-mentioned concrete technical scheme is modified, or carries out equivalent to which part technical characteristic（For example, on more eccentric shaft
Positioning plane is multiple, it is desirable to which the angle between the center line of adjacent positioned plane is less than 180 °, accordingly, the positioning on bushing plate
Plate is also multiple, and the angle between the center line of adjacent positioned plate is less than 180 °, corresponding with the positioning plane on more eccentric shaft）；
And these modifications or replacement, do not make the essence of appropriate technical solution depart from the spirit and model of technical solutions of the utility model
Enclose.
