Description
Technical field
The utility model belongs to a kind of Machining of Connecting Rod instruments of inspection, is mainly used in the dowel hole position measurement of gonnecting rod body.
Background technology
Connecting rod is the core component of engine, is made up of gonnecting rod body and connecting rod cap, gonnecting rod body（See Fig. 1,2）, gonnecting rod body
Dowel hole A, is the position portion for accurately being combined gonnecting rod body and connecting rod cap by alignment pin, dowel hole A site error
It is whether qualified, direct shadow to the overall technical performance of connecting rod, it can cause abnormal conditions occur in engine to cause power failure.
In view of the importance of connecting rod dowel hole, needs to control the position chi of the dowel hole during Machining of Connecting Rod
Very little, the position of gonnecting rod body dowel hole is mainly examined in locating and machining pin-and-hole process and assembling gonnecting rod body and connecting rod cap
Survey.Conventional detection is to use the method to workpiece sampling observation, with three coordinate measurement instruments or multiple detection dowel hole position dimensions
Cubing carry out detection judgement.This detection, efficiency is low, cumbersome, and cost is high, it is impossible to be used in gonnecting rod body is determined on production line
The tracing detection of position pin-and-hole position dimension, causes defective work to flow out.Therefore, it is necessary to a kind of reliable efficiently detection side need to be sought
Formula, to detect gonnecting rod body dowel hole position dimension, to solve the technical barrier on production line.
Utility model content
The technical problems to be solved in the utility model and purpose are：Surveyed according to the existing gonnecting rod body dowel hole position that is used for
It is insufficient existing for amount, design a kind of new instrument for gonnecting rod body dowel hole position measurement.Fundamentally overcome former detection
Low, the cumbersome phenomenon of mode efficiency, reaches and effectively improves detection efficiency, can be used in tracing detection on production line, makes
Workpiece is protected in the quality of this procedure.
Main technical schemes of the present utility model are：Kit for gonnecting rod body dowel hole position measurement is containing connection
Plate, pedestal, positioning core axle, side locating piece, pin, screw, left interchangeable locating piece, right interchangeable locating piece, trip bolt, limit plug
Rule, concrete structure：Along center line right part on pedestal, interference fit installation positioning core axle, along center line left part on pedestal, lead to
Pin and screw seating side locating piece and connecting plate are crossed, connecting plate is threadedly coupled with trip bolt, passes through pin, spiral shell
Left interchangeable locating piece and right interchangeable locating piece are connected by nail, then along center line left part on pedestal
End.
The utility model is proved by practical application：Purpose of design is fully achieved, the position measurement tool construction is simple, easily
Make；It is easy to operate, more than 15 times of efficiency is improved, is fully able to be used for tracing detection on production line, detection accuracy reaches
100%, prevent not conforming to product outflow；Efficiently solve the technical barrier of connecting rod on a production line.

Embodiment
Main technical schemes of the present utility model are illustrated by reference picture 2,3：The utility model includes connecting plate 1, base
It is seat 2, positioning core axle 4, side locating piece 5, pin 6, screw 7, left interchangeable locating piece 8, right interchangeable locating piece 9, trip bolt 10, fixed
Position feeler gauge 11, concrete structure：On the base 2 along center line right part, interference fit installation positioning core axle 4, on the base 2 along center
Line left part, by pin 6 and the seating side locating piece 5 of screw 7 and connecting plate 1, connecting plate is threadedly coupled with trip bolt 10, passed through
Left interchangeable locating piece 8 and right interchangeable locating piece 9 are connected by pin 6, screw 7, then install on the base 2 along center line left part
End.
Reference picture 1,2, the utility model must be according to the size L of gonnecting rod body1、L2、L3Carry out manufacture installation.Left interchangeable positioning
The position dimension at the pilot hole center of block 8 and right interchangeable locating piece 9, it is ensured that with gonnecting rod body dowel hole size L1Unanimously（See
Fig. 6,7）；The distance between pilot hole center of left interchangeable locating piece 8 and right interchangeable locating piece 9 and gonnecting rod body dowel hole center
Size L2Unanimously（See Fig. 3）；Ensure the pilot hole center of left interchangeable locating piece 8 to the size and position chi of side locating piece 5
Very little L3Unanimously（See Fig. 3）；The size that seating side locating piece 5 is manufactured to the big aperture line of centres of connecting rod 3 is L2/2（See Fig. 3）.With
The φ of upper dimensional accuracy and positioning feeler gauge 111、φ2Dimensional accuracy ensures within ± 0.005mm.
Reference picture 5, operation principle of the present utility model：3 small head bore of connecting rod is loaded into positioning core axle 4, makes connecting rod macropore
End face is bonded with the upper surface of pedestal 2, by trip bolt 10, the side of connecting rod 3 is bonded with side locating piece 5 and is consolidated connecting rod
It is fixed；Feeler gauge 11 will be positioned to insert in the pilot hole of left interchangeable locating piece 8, right interchangeable locating piece 9, if two positioning feeler gauges can insert
In the dowel hole of connecting rod 3, then dowel hole size L is judged1、L2、L3It is qualified, on the contrary it is unqualified.Need to readjust processing journey
