Description
Technical field
The present invention relates to detecting tool technical field, more particularly to a kind of piston ring detecting tool.
Background technology
Piston ring (Piston Ring) is the becket for being embedded in inside piston groove, and piston ring is divided into two kinds：Compression
Ring and machine oil ring.Compression ring can be used to the burning mixture in sealing combustion room；Machine oil ring is then unnecessary on cylinder for striking off
Machine oil.Piston ring is a kind of with the larger metallic elastic ring for expanding outwardly deformation, and it is its corresponding that it is mounted to section
In annular groove, the piston ring of reciprocal and rotary motion, by the pressure differential of gas or liquid, in ring periphery and cylinder and ring
Sealing is formed between a side of annular groove.The assembly precision of piston ring requires very high, therefore the circle of the outer ring to piston ring
Degree requires very high, is generally all to judge whether its circularity accords with by the external diameter of vernier caliper measurement piston ring different parts at present
Close and require, this detection side has larger error, and piston ring is relatively large in diameter, and axial width is smaller, common vernier calliper
Chi is difficult to find diameter accurately, therefore accuracy of detection is low, detection efficiency is low.Also it is to press from both sides piston ring by scroll chuck to have a kind of method
Detected again with amesdial head after holding, because piston ring diameter is big, axially very short, scroll chuck can only clamp seldom portion
Position, this circumference for resulting in piston ring is difficult concentric with scroll chuck, and detection error is big；It is living and the thickness of piston ring is smaller
Plug ring is easily deformed after being clamped by scroll chuck, causes testing result very big with actual deviation；For the ease of the folder of piston ring
Hold, generally also position piston ring by fixture, then scroll chuck clamping fixture is detected, the assembling of piston ring and fixture,
Dismounting is wasted time and energy, and detection efficiency is low.
The content of the invention
There is provided one in order to solve the problem of piston ring detection efficiency of the prior art is low, accuracy of detection is low by the present invention
