Description
Technical field
The present invention relates to roll test equipments, particularly, are related to a kind of roll crown measuring device.
Background technique
In the production of the plate band of steel industry and non-ferrous metal industry, roll is in one of plate rolling process
Important part of appliance, it is the pressure that generates when being rolled in opposite directions using a pair of or one group of roll to roll stone roller Strip.Roll
Working condition directly affects the effect of Rolling Production.During rolling processing, due to factors such as temperature, abrasions, roll can
It can deform, this deformation includes mainly the roll middle part generated due to the intermediate position of roll than axial ends serious wear
Position diameter is small, and the big situation of two-end part diameter (i.e. roll wear convexity) makes the axial profile curve of roll also change,
And then affect the effect of rolling of roll.In order to guarantee the quality of processing, roll is before upper milling train and after a period of use
It has to roll crown (roll shape) by measurement and inspection, therefore it is very heavy for correctly detecting roll whether to meet required precision
It wants.In the measuring device traditional using such as micrometer and saddle instrument, part is economical real for domestic also many producers at this stage
The strong large enterprises of power then use external roll shape measuring instrument, and instrument is huge, and cost is also high.
Chinese patent 201210408108.5 discloses a kind of roll profile measuring device, and the program needs to be rolled according to tested
The different-diameter size of roller designs and makes the measuring device of different measurement ranges, and versatility is not strong, is unfavorable for cost control；Separately
Outside, the program needs to live the diameter envelope of entire roll, i.e., two support rod needs to keep 90 degree of angle in measurement
And keep two support rods tangent with roll surface simultaneously, therefore, which need to occupy larger space in measurement, grasp
It is inconvenient to make, in addition, the program needs to remove roll from milling train in measurement, and need to clear up roll radially opposite sides when measurement
Space enables two support rods to extend to roll radially opposite sides simultaneously, could normally measure, and therefore, the program is not suitable for place
Inadequate situation and the case where be not suitable for in-site measurement, influences production efficiency.
With steel industry and and metallurgical technology continuous development, the measuring mechanism of roll is also correspondingly proposed higher
Requirement, in order to adapt to measure small in size, precision is high, cost is low, it is high-efficient, easy to operate, do not influence production etc. require,
The new roller measure mechanism of one kind is developed to be necessary.
Summary of the invention
It is an object of that present invention to provide a kind of roll crown measuring devices, to solve the problems, such as to propose in background technique.
To achieve the above object, the present invention provides a kind of roll crown measuring device, including support frame 1,1 bottoms of support frame
