Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in Figure 1, Figure 2 with shown in Fig. 3, the utility model is a kind of offset measuring instrument, comprises holder 1, eccentric reading device, measurement mechanism and locating device; Described eccentric reading device is made up of stem stem 2, slider pad 3, survey key seat 4 and survey pin 5, and have the mesopore longitudinally run through in the middle part of described holder 1, stem stem 2 is slidably mounted in mesopore; Described holder 1 has and laterally runs through groove and longitudinally run through groove, described slider pad 3 is fixed through stem stem 2 and is arranged at and laterally runs through in groove, slider pad 3 and the transverse direction on holder 1 run through groove bottom land and contact and energy relative sliding, described survey pin 5 is fixedly mounted on to be surveyed in key seat 4 mesopore, surveys pin 5 and is fixedly mounted on slider pad 3 by surveying key seat 4; Described measurement mechanism is made up of dial gauge 6, dial indicator holder 7 and dynamometry stage clip 8, dial gauge 6 clamping is arranged on dial indicator holder 7, dial gauge 6 is fixedly connected on one end of holder 1 by dial indicator holder 7, dial gauge 6 gauge head contact with stem stem 2 end face and dial gauge 6 gauge head center just to stem stem 2 center; Described dial gauge 6 front end installs dynamometry stage clip 8 and dynamometry stage clip 8 is arranged between mandrel 2 end face and dial indicator holder 7; Described locating device is made up of mandrel seat 9 and positioning core axle 10, and positioning core axle 10 is fixedly mounted in the mesopore of mandrel seat 9, and positioning core axle 10 is slidably mounted on holder 1 by mandrel seat 9 and longitudinally runs through in groove; Described positioning core axle 10 and the axial line surveying pin 5 are parallel to each other and perpendicular to the upper surface of holder 3.
Measured workpiece is located by positioning core axle 10 and is arranged on holder 1 upper surface.Before apparatus measures, first select the positioning core axle 10 of corresponding external diameter according to tested part median pore diameter size, and be fit in mandrel seat 9 also fixing.According to tested part eccentric orfice pore size, adjustment mandrel seat 9 and the distance surveying key seat 4; First survey key seat 4 is fixedly mounted in slider pad 3 groove, again mandrel seat 9 is installed to holder 1 and longitudinally runs through in groove and shift position, measured workpiece is installed to when positioning core axle 10 rotates can make survey pin 5 contact with eccentric orfice inner hole wall all the time, and make slider pad 3 be in holder 1 laterally the two limit positions run through in groove all can not collide with both sides cell wall, namely gap, both sides is substantially identical.After meeting this condition, fastening positioning core axle 10, then adjust dial gauge 6 clip position, when making slider pad 3 and stem stem 2 be displaced to two limit positions, dial gauge 6 all can not exceed its range with stem stem 2 end contact.Measured workpiece is rotated again after measuring instrument has adjusted, stop operating when maximum (or minimum) measured value turning point appears in indicating value on dial gauge 6 workpiece, dial scale is stirred, calibrates dial gauge 6 scale value zero-bit to turning point, in this, as workpiece misalignment measurement starting point; Rotate measured workpiece again to measure, and write down the indicator rotation number of turns and little dial scale, stop operating when again going out to reveal minimum (or maximum) measured value turning point, now on dial gauge 6, measured value and zero-bit difference are two times of values of workpiece offset.During measurement, measured piece mesopore is felt relieved by the positioning core axle 10 in locating device and is located and rotate around it; Survey pin 5 on measurement mechanism contacts with tested eccentric hole wall all the time under dynamometry stage clip 8 acts on, and its displacement shows on the dial gauge 6 of eccentric reading device, and the difference of its maximum measured value and minimum measured value is the diploidy number value of measured piece offset.Locating device and measurement mechanism all have micro-adjusting mechanism, and its relative distance is adjustable.Described mandrel seat 9 and survey the adjustment part that key seat 4 is measuring instruments, between relative distance adjustable; Described positioning core axle 10 is renewal parts of measuring instrument, and its diameter is replaceable.Measured to adapt to the workpiece different with offset to different pore size with replacing by the adjustment of the two.Positioning core axle 10 is renewal parts of measuring instrument, and the tested part according to different median pore diameter is equipped with; Positioning core axle 10 and measured piece mesopore are slidably matched and locates, unidirectionally under dynamometry stage clip 8 effect eliminate clamping gap that part mesopore dimension deviation causes to the impact of measured value, guarantee accurate positioning.
Slider pad 3 can move along stem stem 2 axis direction in holder 1 horizontal running through between groove translot, and dynamometry stage clip 8 can ensure that surveying pin 5 fully fits with tested part when piece test and slider pad 3 can be resetted when nothing detects part.The function of measuring instrument: when being arranged on measured workpiece on positioning core axle 10 toward same direction rotation measuring, the dial gauge 6 of eccentric reading device demonstrates ascending, descending again measured value, and the difference of maximum measured value and minimum measured value is the diploidy number value of measured piece offset.Slider pad 3 drives dial gauge 6 pointer beat with the displacement of stem stem 2, and indicating value is changed.Mandrel seat 9 can move in holder 1 longitudinal running through in groove and fix; Surveying key seat 4 fixedly mounts in slider pad 3 groove, and this surveys key seat and also can move to adapt to different tested parts in slider pad 3 groove according to aperture and eccentric size.Measuring instrument adopt the positioning core axle 10 of axis parallel and survey pin 5, positioning core axle 10 and plane positioning workpieces, survey pin 5 displacement tested defeat spring 8 act on and stablely with tested eccentric hole wall all the time to contact, stem stem 2 and the unidirectional blind-mate of pore wall, the measuring error because workpiece size deviation causes can be eliminated.Offset between the pump housing class mesopore that measuring instrument can be parallel to each other for measuring center line quickly and easily and eccentric orfice.
Embodiment 2, the basis of embodiment 1 is optimized design to survey key seat 4 and mandrel seat 9, and described survey key seat 4 and mandrel seat 9 can reverse 180 ° of installations; According to eccentric orfice aperture, reverse 180 ° of installations are carried out to survey key seat 4 and mandrel seat 9, to adapt to different tested part apertures, strengthen measuring instrument versatility.
Embodiment 3, the basis of embodiment 1 is optimized design to the fixed part of positioning core axle 10, and for detecting different parts, the fixed part that positioning core axle 10 is arranged in mandrel seat 9 is all constant; Positioning core axle 10 is renewal parts of measuring instrument, and the tested part according to different median pore diameter is changed; The bottom mounting part size of various positioning core axle 10 is unified, saves material while strengthening equipment interoperability; The positioning core axle 10 of different size is all slidably matched with measured piece mesopore, guarantees accurate positioning, stability of rotation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
