Abstract
The utility model discloses wide utensil of examining of crankshaft journal shelves, including go side model and not -go -end model, the go side model is the same with not -go -end model shape, and characterized by constitutes by convex model (1) with at convex model (1) up end middle part fixedly connected with handle (2), and interior arc surface (11) the diameter of convex model (1) is unanimous with crankshaft journal's diameter. Its simple structure uses the influence of testing process human factor little, and the accuracy is high, and the testing process can be slided along the circumferencial direction and detected, does not need the pointwise to detect, and the convenience saves time.
Description
Technical field
The utility model relates to the device for being detected wide to crankshaft journal shelves.To judge the wide chi of crankshaft journal shelves
It is very little whether to reach design requirement.
Background technology
The wide cubing of existing crankshaft journal shelves is a kind of straight panel plate cubing, and straight panel is in I shape, and one end is go side model, separately
One end is not-go-end model（Accompanying drawing 1）, the go side model width of model side is the lower limit of the wide design size of crankshaft journal shelves,
High limit of size model of the not-go-end model width of model opposite side for the wide design size of crankshaft journal shelves, its using method is：
The first step, it is wide to crankshaft journal shelves first to carry out test run and cut a knife, as long as last process knife festooned vehicle is fallen；
Second step, test run are inserted into crankshaft journal shelves sipes with the go side A of model after cutting, and such as insert not enter, then
Again feed carries out turnery processing, then reexamines, until the go side A of model can be inserted in crankshaft journal shelves sipes；
3rd step：Inserted into crankshaft journal shelves sipes with the not-go-end B of model, such as insert not enter, illustrate to have reached
To design size, if can insert explanation has been above design size.
This model detection mode, in detection process, template surface is on the axial line tangent plane of axle journal, anthropic factor shadow
Sound is larger, and accuracy is poor；And deform as bent axle is present in the course of processing, therefore circumferentially will examine in detection process
Many places are surveyed, detection time is long.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, easy, the easy to use wide inspection of crankshaft journal shelves of manufacture
With convenient and swift, tool, accurately detects whether the wide size of crankshaft journal shelves is qualified.
The wide cubing of this utility model crankshaft journal shelves, including go side model and not-go-end model, go side model and not-go-end model
Shape is the same, by circular arc model 1 and is fixedly connected with handle 2 in the middle part of 1 upper surface of circular arc model and constitutes, circular arc model
1 11 diameter of inner arc surface is consistent with the diameter of crankshaft journal, in the left side 12 and right edge 13 and inner circle of circular arc model 1
Chamfering 12 ', 13 ' is provided between cambered surface 11, the width of the circular arc model 1 of go side model is under the wide design size of crankshaft journal shelves
Limit size；The high limit of size of the width of the circular arc model 1 of not-go-end model for the wide design size of crankshaft journal shelves.
The wide detection tool structure of this utility model crankshaft journal shelves is simple, and manufacture is easy.
When this utility model is used：
The first step, it is wide to crankshaft journal shelves first to carry out test run and cut a knife, as long as last process knife festooned vehicle is fallen；
Second step, test run are inserted into crankshaft journal shelves sipes with go side model after cutting, and such as insert not enter, then again
Feed carries out turnery processing, then reexamines, until the go side A of model can be inserted in crankshaft journal shelves sipes；
3rd step：Inserted into crankshaft journal shelves sipes with not-go-end model, such as insert not enter, illustrated to have reached and set
Meter size, if can insert explanation has been above design size.
In this utility model detection process, model aligns axial line tangent plane without manual operation, and anthropic factor affects little, accurate
Really property is high；And detection process circumferentially can be slided detection, it is not necessary to which pointwise is detected, saved time conveniently.
This utility model quickly can be detected to the wide size of crankshaft journal shelves online, so that it is determined that further cut
The depth of cut, detects whether to have reached design size requirement.

Specific embodiment
The wide cubing of this utility model crankshaft journal shelves, including a go side model and a not-go-end model, go side model and
Not-go-end model shape is the same, by circular arc model 1 and is fixedly connected with handle 2 in the middle part of 1 upper surface of circular arc model and constitutes, circle
11 diameter of inner arc surface of arc model 1 is consistent with the diameter of crankshaft journal, in the left side 12 and right edge of circular arc model 1
Chamfering 12 ', 13 ' is provided between 13 and inner arc surface 11, the width of the circular arc model 1 of go side model is the wide design of crankshaft journal shelves
The lower limit of size；The high limit of size of the width of the circular arc model 1 of not-go-end model for the wide design size of crankshaft journal shelves.
Claims (1)
1. the wide cubing of crankshaft journal shelves, including go side model and not-go-end model, as not-go-end model shape, which is special for go side model
