A kind of steel plate non-planeness measurement instrument
The utility model is specifically related to a kind of steel plate non-planeness measurement instrument, belongs to steel sheet product Quality Inspection Tool technical field.
Unevenness refers to the wave height that flat rolled piece waveform is bending and length ratio, the inspection of steel plate unevenness is requisite link in the quality control of production Wide and Thick Slab, the method of inspection generally takes range estimation or straight steel ruler and tape measure or ruler conjunction measuring, GB " the size of GB/T709-2006 hot-rolled steel plates and sheets, profile, weight and permissible variation " in regulation detect the method for unevenness and be, steel plate is freely put in the plane, any pressure is not applied except the weight of steel plate own, be the ruler of 1000mm or 2000mm by a length, apart from single rolled steel plate longitudinal edge at least 25mm and be at least any direction in 200mm region apart from horizontal edge, measure the ultimate range between upper surface of steel plate and ruler, the shortcoming of current steel plate non-planeness measurement decision method is: 1. because Plate Production rhythm is fast, checking measurements speed is difficult to meet production requirement, 2. straight steel ruler and tape measure or ruler conjunction measuring one people are difficult to operate, 3. survey instrument is not easy to carry with.
Utility model content
Therefore, the utility model object is to provide that a kind of structure is simple, cost is low, simple to operate, safe and reliable and be convenient to the steel plate non-planeness measurement instrument carried with, comprise straight steel ruler, it is characterized in that, described steel plate non-planeness measurement instrument also comprises two neodymium iron boron suspension ring suckers and a crystal line, and described crystal line is connected between two neodymium iron boron suspension ring suckers.
Further, described neodymium iron boron suspension ring sucker is circular magnetic chuck, and diameter is 25mm.
Further, described crystal line length is 1m or 2m, and diameter is at more than 0.8mm.
Further, described straight steel ruler length is 150mm.
The beneficial effects of the utility model are: steel plate non-planeness measurement instrument of the present utility model, have that structure is simple, cost is low, simple to operate, safe and reliable and be convenient to features such as carrying with, realize a people to operate easily, steel plate unevenness can be measured rapidly and accurately, improve rhythm of production and detection efficiency, be applicable to Plate Production enterprise and use as checking measurements instrument.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of steel plate non-planeness measurement of the utility model instrument.
Reference numeral is as follows:
1, straight steel ruler;
2, neodymium iron boron suspension ring sucker;
3, crystal line.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
As shown in Figure 1, a kind of steel plate non-planeness measurement instrument, comprises straight steel ruler 1, it is characterized in that, steel plate non-planeness measurement instrument also comprises two neodymium iron boron suspension ring suckers 2 and a crystal line 3, and crystal line 3 is connected between two neodymium iron boron suspension ring suckers 2.Neodymium iron boron suspension ring sucker 2 magnetic force is strong, and firmly can adsorb on steel plate, crystal line 3 transparency is good, is easy to observed reading, and has certain elasticity, can tighten.
Preferably, neodymium iron boron suspension ring sucker 2 is circular magnetic chuck, and diameter is 25mm.Circular magnetic chuck is convenient to measurement operation more.
Preferably, according to actual service condition, by Standard, the crystal line 3 in survey instrument can be fixed on the length of 1m or 2m, be convenient to make a determination efficiently and effectively when measuring unevenness.Also can need according to enterprise practical the length adjusting crystal line 3, crystal line 3 diameter, at more than 0.8mm, ensures that crystal line 3 can not be pulled off.
Preferably, straight steel ruler 1 length is 150mm.Select shorter straight steel ruler 1 just can meet non-planeness measurement requirement, be easy to carry.
When actual enforcement is measured, in measurement of the steel plate position, 2 neodymium iron boron suspension ring suckers 2 can be adsorbed on steel plate according to standard-required, under making the crystal line 3 between two neodymium iron boron suspension ring suckers 2 be in tensioned state, the maximum gap between crystal line 3 and steel plate measured by use straight steel ruler 1, can measure uneven angle value.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
