Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.Should be understood that embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
Referring to Fig. 2 and Fig. 4, the parallelism measuring apparatus that the utility model relates to comprises fabricated section 11 and is used at least two measuring pieces of measuring height that fabricated section 11 is platy structure, but is not limited to platy structure.Described measuring piece is installed on the fabricated section 11, in order to simultaneously the difference of unit under test 4 is measured.
For example, as shown in Figure 4, parallelism measuring apparatus is in measuring state.Unit under test 4 comprises A part and B part, the B part take A partly as the depth of parallelism requirement of benchmark below 0.04mm/100mm.Now need to measure tested part B part take A partly as the depth of parallelism of benchmark.
Therefore, the process of carrying out the measurement of paralleism by said structure is: at first obtain height value K1 and the K2 of the difference of unit under test by measuring piece, then calculate 2 height difference H=|K1-K2|, according to computing formula
Draw the depth of parallelism of unit under test
(wherein, M is two distances between the measuring piece, P be the B part of unit under test take A partly as the depth of parallelism value of benchmark).
As mentioned above, owing to do not need to regulate the position of measuring piece, thereby parallelism measuring apparatus of the present utility model has easy to operate advantage, and avoided affecting because regulating measuring piece the problem of measuring accuracy.Wherein, in the situation that comprises two measuring pieces, can a plurality of measuring pieces be installed at fabricated section 11, thereby can according to measuring accuracy, select any two measuring pieces to carry out the measurement of paralleism.In addition, parallelism measuring apparatus of the present utility model can move arbitrarily, is not subjected to the restriction of test desk during measurement, thereby has higher measurement dirigibility.
Fig. 2 to Fig. 4 has shown preferred implementation of the present utility model.Wherein, parallelism measuring apparatus comprises magnetic part 12, and this magnetic part 12 is fixed on the downside of the end of fabricated section 11.By increasing magnetic part 12, when measuring the unit under test 4 of metal material, magnetic part 12 and unit under test 4 adhesives, thus unit under test 4 can be fixed, avoided unit under test 4 to move and the measuring error that produces.
Be appreciated that magnetic part 12 can be polytype magnetic part, other magnetic instruments that form such as magnetic patch, magnetic stand or by magnet etc.The preferred magnetic stand that adopts is as magnetic part 12 in the utility model.As known to those skilled in the art, be provided with rotary switch at magnetic stand.When measuring when operation, rotary switch is placed the open site, magnetic stand produces the magnetic line of force, thus with unit under test 4 adhesives of metal species, and then fixing unit under test 4.When measuring end, rotary switch is placed off-position, magnetic stand no longer produces the magnetic line of force, in order to separate with the unit under test 4 of metal species.Be known in those skilled in the art for the inner structure of magnetic stand and the principle etc. that produces the magnetic line of force, do not elaborate at this.In addition, for improving the measuring accuracy of the depth of parallelism, Magnetic gauge stand and fabricated section 11 are formed as one.
In a kind of embodiment of the present utility model, two measuring pieces are installed on the fabricated section 11 movably, like this by regulating measuring piece in fabricated section 11 positions, the length that can adapt on the one hand actual unit under test 4, the distance between the measuring piece can be regulated on the other hand, thereby different parallelism precisions can be obtained.Wherein, measuring piece is installed in movably fabricated section 11 and can be accomplished in several ways, and does not repeat them here.
In Fig. 2 and embodiment illustrated in fig. 3, two measuring pieces are fixed on the fabricated section 11, in order to accurate measurement of paralleism value is provided.
Particularly, described measuring piece can be the polytypes such as milscale, pit gauge.Be preferably pit gauge 13 in the utility model, this pit gauge 13 comprises chi head 13a and perpendicular to the dip stick of fabricated section 11, wherein chi head 13a is fixed on the fabricated section 11, and dip stick 13b is installed on the chi head 13a movably.By vertical mobile dip stick 13b, thereby record the height of the difference of unit under test 4.
Be appreciated that the side that chi head 13a is fixed on fabricated section 11 just can realize measuring.In the utility model, be preferably at fabricated section 11 fixed installation pieces 14, chi head 13a is fixed on the fabricated section 11 indirectly by being fixed on the mounting blocks 14.Movement and measurement in order to realize dip stick 13b are provided with through hole at fabricated section 11, after dip stick 13b passes this through hole, can contact with unit under test 4, to measure.Usually, pit gauge 13 is marked with scale, can directly read measured value.
Preferably, when pit gauge 13 is the digital display pit gauge, can comprise the display screen 13c for the display measurement value, this display screen 13c is installed on the chi head 13a.Adopt the digital display pit gauge can read the exact value of measurement, to improve the precision of the measurement of paralleism.And along with the raising of the measuring accuracy of digital display pit gauge self, the measurement of paralleism precision of parallelism measuring apparatus of the present utility model also can improve thereupon.
In addition, before carrying out the measurement of paralleism, preferably include whole depth of parallelism device is carried out initialization operation.Referring to Fig. 3, parallelism measuring apparatus of the present utility model can comprise standard 15, as long as this standard 15 has the higher plane of the depth of parallelism and namely can be used for the parallelism measuring apparatus initialization, being about to magnetic part 12 is placed on the standard 15, dip stick 13b contacts with standard 15, and with the registration zero setting of display screen 13c, finish initialization operation, measure again afterwards operation.
In addition, standard 15 can also have the function of depositing.Preferably, standard 15 comprises and the first reference field 15a and the second reference field 15b that the first reference field 15a is lower than the second reference field 15b, and magnetic part 12 can be supported on the first reference field 15a.Because magnetic part 12 is fixed on the downside of fabricated section 11, be not easy to deposit, thereby make standard 15 comprise the reference field that height is different, in the time of on magnetic part 12 being supported on lower reference field (the first reference field 15a), just can reaching and deposit easily effect.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove in addition, each concrete technical characterictic described in above-mentioned embodiment in reconcilable situation, can make up by any suitable mode, for fear of unnecessary repetition, the utility model is to the no longer separately explanation of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
