Description
Technical field
The present invention relates to Production of Crankshaft technical fields, in particular to a kind of bent axle to index scribing tooling.
Background technology
It is well known that bent axle is made of trunnion and connecting rod neck, connecting rod neck usually decentered distribution at a certain angle, every time
Its center must go to main shaft rotation center when processing connecting rod neck, swing back and forth biography equipped with crank mechanism on each grade of connecting rod neck
Graduating power.So as soon as the number of bent axle upper connecting rod neck is more, the power transmitted is bigger.Such as six-cylinder engine bent axle
Connecting rod neck number refer to just there are six, usually in 120 ° distribution, this angular phase distribution precision it is higher, the property of bent axle
Energy, quality are better.If otherwise indexing positioning is inaccurate, it is domestic generally to require indexing accuracy in scholar 15 ', more than connecting rod neck can be caused
Center and main shaft rotation center are misaligned, cause larger mismachining tolerance, such as lose circle, or even bent axle is caused to scrap.It is existing common
The grinding crank-shaft link neck fixture used on crankshaft grinding machine includes eccentricity adjustment mechanism and clamp system, indexing mechanism etc..For
Adjustment eccentricity need to install a series of parts, and the leading screw that is mounted in terminal pad such as terminal pad, by fixing sleeve is mounted on folder
The nut mating with leading screw particularly, terminal pad one end are installed on machine tool chief axis, and the other end passes through dovetail or rectangular guideway
It is connected with clamp body, rotational lead screw drives clamp body to be moved relative to terminal pad by nut, adjusts required by different bent axles
Eccentricity.Indexing mechanism generally use is index dial, using index dial to the method for positive groove, when this structure operation not only
It is time-consuming, also it is difficult to ensure required precision.
Another indexing mechanism is to realize that indexing, indexing mechanism are equipped with distribution using the location hole on crankshaft flange end face
Several taper location holes in fixture base, the taper positioning column in one taper location hole of left clamp body and its operation
Device, T-bolt clamping fixture, it includes the positioning being mounted on left clamp body that need to separately be equipped with detent mechanism detent mechanism
Disk, positioning disk are equipped with the positioning pin coordinated with crankshaft flange end face location hole and positioning pin telescopic control device.This structure
It needs to increase by one layer of fixture base between disk in clamp body and as transition couple with connecing, and in order to realize circular index, fixture
A pair of of rolling bearing must also be installed to be used for supporting between body and fixture base.From the above, it can be seen that being manufactured by above structure
Entire clamp body have that layer of structure is more, the long, poor rigidity of overhanging, processing part amount are big, and the dovetail of adjustment eccentricity
Or rectangular guideway processing trouble purchases outsourcing piece bearing again to ensure that precision will also carry out scraping to guide pass, it is with high costs
The shortcomings of, it would be highly desirable to it improves.
Invention content
The technical problem to be solved by the present invention is to overcome prior art disadvantage, provide a kind of bent axle indexing scribing tooling, knot
Structure is reasonable, easy to operate, efficiently and accurately.
In order to solve the above technical problems, technical solution provided by the invention is：A kind of bent axle indexing scribing tooling, including bottom
Seat, the base body shape are cuboid, are equipped with midfoot support block at the pedestal central upper portion, on the midfoot support block
Rotation is equipped with rocking arm at portion center, and the initial bit of the rocking arm is placed parallel to the longer sides of pedestal, the pedestal upper rocker arm
It is respectively equipped with horizontal concrete chute at end positions, matched sliding block is equipped in the horizontal concrete chute, the slider body is Shang shapes,
The both sides of the horizontal concrete chute are respectively equipped with sliding block pressing plate, and the sliding block slides between horizontal concrete chute and sliding block pressing plate, described
The both ends bottom of rocking arm is by the lower part of two connection sliding block of straight pin, and one end and sliding block opposite side are equipped with rotation on the rocking arm
Block, for the moving block by one connecting rocker arm of straight pin, the horizontal concrete chute is equipped with supporting block holder in moving block one end,
The supporting block pedestal upper end is connected with leading screw support briquetting, and the supporting block holder and leading screw support briquetting junction are equipped with recessed
Mouthful, it is equipped with leading screw supporting block in the recess, matched drive lead screw, the drive lead screw are equipped in the leading screw supporting block
One end connects moving block, and the other end is fixed with runner.
As an improvement, two horizontal concrete chutes are mutually parallel and are each perpendicular to the longer sides of pedestal, facilitate sliding laggard
Row indexing.
As an improvement, the upper surface of the sliding block pressing plate is less than the lower surface of rocking arm, rocking arm will not encounter sliding block when rotating
Pressing plate.
As an improvement, the sliding block is respectively arranged at the not homonymy of rocking arm, homonymy can not clamp bent axle conveniently.
As an improvement, on the drive lead screw and moving block junction is equipped with bearing, rotation is more smooth, reduces abrasion.
The advantages of the present invention over the prior art are that：Rapidly crankshaft-link rod can be indexed by sliding block, it is non-
Chang Gaoxiao, while process is simple, reduces error caused by human factor influences, present inventive concept is ingenious, simple in structure, user
Just, it is with a wide range of applications, is suitble to promote and apply.
