Description
Technical field
The utility model relates to the pick-up unit of a kind of numerically-controlled machine, digital display machine tool linear axis positioning precision and repetitive positioning accuracy, also can be used as a kind of standard instruments in other length dimension metering detection, specifically a kind of combined type horizontal-vertical double-purpose step gage, belong to machinery standard product manufacturing technology field.
Background technology
The step gage used now is to measure by pottery the length dimension material standard gauge that gauge block, steel gauge block and step gage base body are spliced.Whether it accurately directly affects tested length dimension levels of precision.
The national standard " JB/T10977-2010 " of step gage issued in 7 labourer hired by the month letter radicals by which characters are arranged in traditional Chinese dictionaries in 2010.In September, 2010, the State Bureau of Quality Supervision issued step gage calibrating standard " JJF1258-2010 ".Should belong to a kind of new product.
1, the structure of existing step gage:
The structure of using now step gage is to be spliced by several 10mm pottery measurement gauge blocks and steel gauge block.
2, now use the accuracy class (in Table 1) of step gage:
3, now use the defect of step gage:
We find in detecting numerically-controlled machine, and the step gage of 300mm of take is example, and the step gage dimensional stability in use is bad.Subsequently in the time more than a year to this step gage the thermal expansion amount under the natural temperature condition, carried out a large amount of detection research, find that step gage has two large defects.
The firstth, fault of construction, it is to be spliced by 16 10mm pottery measurement gauge blocks and 15 10mm steel gauge blocks (cushion block), each gauge block inevitably exists planarity, collimation, size, installation error factors, it after splicing, can not be a rigid body, while varying with temperature and the thermal expansion amount of standard gauge block very big difference is arranged, return less than original size when temperature rises and descends, therefore at different temperature, produce the larger creep of difference.
Second defect is that pottery is different from the thermal expansion coefficient of steel material, and pottery is 9.5 * 10
-6℃, steel is 11.5 * 10
-6℃, two large defects all affect the step gage dimensional accuracy, in use, can produce very large measuring error.
The accuracy class of table 1 step gage
the utility model content
The utility model purpose just is to overcome existing step gage, rigidity deficiency structurally, and thermal expansion coefficient difference on material, produce creep and the bad defect of dimensional stability with temperature, thereby a kind of new technical scheme be provided.
For achieving the above object, the utility model can be realized by following scheme:
The dual-purpose step gage of the sleeping step of a kind of Combined vertical, it is by the step gage base body, step pitch is measured piece and is formed, the step gage base body is " work " character form structure, be provided with the entire body groove on I-shaped step gage base body, be inlaid with step pitch and measure piece in the entire body groove, be provided with the base body through hole on the step gage base body; Described step gage base body one end is provided with the step gage positioning seat, and the other end is provided with the step gage top board, and step gage positioning seat and step gage top board and step gage base body are fixedly connected by attachment screw and top board jackscrew.
The step pitch that is equipped with on the entire body groove of step gage base body is measured on piece and is provided with the concavo-convex notch that corresponding measurement size uses is the rectangular strip toothing.
Be provided with the step gage positioning seat that can be used for adjusting verticality at step gage base body one end.
The advantage that the utility model compared with prior art had is: the globality structure, good rigidly, cheap, easy to assembly, can stand sleeping installing and using, thermal expansion coefficient is identical with tested lathe, use error is little, and measuring accuracy is high, can overcome the measuring error caused because of temperature variation fully, can adapt to the testing requirement under normal temperature, greatly improve quality and the detection efficiency of product.
The accompanying drawing explanation
Embodiment
To be embodied as example, the utility model is described in further details by reference to the accompanying drawings now:
A kind of combined type horizontal-vertical double-purpose step gage, it is by step gage base body 4, the steel step pitch is measured piece 3 and is formed, step gage base body 4 is " work " character form structures, be provided with the entire body groove on I-shaped step gage base body 4, the step pitch that is inlaid with steel material in the entire body groove is measured piece 3, the step pitch that is equipped with on the entire body groove of described step gage base body 4 is measured piece 3, and to be provided with the concavo-convex notch that corresponding measurement size uses be the rectangular strip toothing, be provided with base body through hole 5 on step gage base body 4, can alleviate the overall weight of step gage and reduce distortion; Be provided with the step gage positioning seat 6 of capable of regulating verticality at an end of step gage base body 4, for adjusting and step gage base body 4 verticality by the depth of parallelism of grinding or scraping step gage positioning seat 6 when assembling, the other end is provided with step gage top board 1, its objective is that step pitch is measured to piece 3 to be pressed on step gage base body 4.Step gage positioning seat 6 and step gage top board 1 are fixedly connected by attachment screw 7 and top board jackscrew 2 with step gage base body 4.
