Description

The multinomial order instrument for measuring bearings of hand-held
One, technical field:
The utility model relates to a kind of measurer of measuring bearing, the multinomial order instrument for measuring bearings of a kind of hand-held is particularly disclosed, be applied to the measurement of large-scale, heavy revolving parts (as bearing, bearing ring etc.), particularly the tested part placement is motionless, and multinomial range estimation amount is carried out in the multinomial order instrument for measuring bearings rotation of hand-held.
Two, background technology:
Bearing is the high precision standard part, has both required high dimension precision, more exigent shape and positional precision.So adopt the bearing special testing instrument to come each special detection project is compared measurement usually.
Its advantage is: various bearing special testing instruments existing standard in bearing industry is used regulation, can guarantee every accuracy detection of bearing.
Its shortcoming is: general bearing special testing instrument only is fit to the measurement on a surface, as internal diameter, external diameter, width, raceway, wall thickness etc., so making a cover large size bearing needs several bearing instrumentations to carry out surveying work.Particularly because measurement data above can the obtaining that workpiece need be rotated a circle on instrument, because the large size bearing part not only greatly but also heavy, can cause during measurement:
1, because workpiece is too heavy, the end face fulcrum on the instrument can grind vestige to workpiece, influences the workpiece presentation quality;
2, since the large size bearing part not only greatly but also heavy, the improper bump toward instrument on during placement can cause the instrument misalignment;
3 by the very heavy workpiece of artificial rotation then labour intensity is very big;
4, when bearing parts was big or heavier, bearing parts had been difficult for moving, even when bearing parts was big especially or heavy especially, bearing parts had been removed motionless, common bearing special testing instrument and can't have been used.Can only use simple and easy measurers such as slide calliper rule, bridge chi, pipe chi to do the measurement of dimensional accuracy, these measurer repeatable accuracys are not high, so measuring accuracy is not high.These measurers can't be measured the accuracy of form and position simultaneously.
Large size bearing is because in batches less, the cost per unit height, and for avoiding producing waste product, frequent measuring workpieces, and loading and unloading repeatedly, artificial labour intensity is very big.
Three, summary of the invention:
The purpose of this utility model is to overcome the weak point that prior art exists, and it is few to solve special bearing detecting instrument measurement project, and Workpiece Rotating labour intensity is big, even the problem that at all can't rotate, discloses the multinomial order instrument for measuring bearings of a kind of hand-held.
The utility model is achieved in that the multinomial order instrument for measuring bearings of a kind of hand-held, comprise the mobile jib, the secondary bar that constitute the basic frame of instrument, it is characterized in that: the secondary bar of described instrument stand is perpendicular to mobile jib, interface point is at the mobile jib mid point, three termination point casings of major and minor bar are equipped with the end face locating device and the measurement bay of adjustable distance on bar, three measurement bay vertical lower side are equipped with main fixedly gauge head, secondary fixedly gauge head and main gauge head respectively, the other end of main gauge head measuring junction connects main meter, and the main fixedly vertical lower side of gauge head also is equipped with secondary meter.The master of described three measurement bay vertical lower side fixedly gauge head, secondary fixedly gauge head and main gauge head is separately positioned in the groove beam with three measurement bay elongated slots connected vertically, and three gauge heads upper and lower vertical range in the groove beam of elongated slot is adjustable, and with groove beam axis normal.Described three end face locating devices and the position of measurement bay on major and minor bar, end face locating device in the outside, measurement bay is in the inboard; After also can the measurement bay Rotate 180 ° measurement bay in the outside, the end face locating device is in the inboard.
The utility model adopts lightweight apparatus structure, and workpiece is placed motionless and with the method that detecting instrument rotates, come the multiple parameter project of large size bearing is measured.Can be implemented in simultaneously and needn't unload workpiece on the lathe and measure.Particularly the utility model can substitute existing multiple bearing special testing instrument, alleviates the labour intensity when measuring, and is implemented on the lathe and measures, and reduces the resetting error.
Measuring method of the present utility model is: the basic framework of instrument comprises mobile jib, secondary bar, determined the benchmaring plane of instrument by adjusting 3 end face locating devices, determined a radial measurement plane and measured diameter by adjusting main fixedly gauge head, secondary fixedly gauge head and main gauge head, at this moment by on standard component or exemplar, demarcating the zero-bit of main meter, the dimensional accuracy that can read tested part from main meter.Particularly: it is above under this measurement situation instrument to be rotated a circle, and can read the deviation from circular from of tested part from main meter, can read the vertical difference and the angle precision of tested part from secondary meter.The multinomial order instrument for measuring bearings of hand-held according to position shown in the accompanying drawing is adjusted is used for the bearing bore diameter parameter measurement; As 3 measurement bays in the multinomial order instrument for measuring bearings of hand-held and annex Rotate 180 ° are installed on outside the end face locating device, can be used for the bearing outside diameter parameter measurement.In addition, annex and meter can be increased again if needed, other parameter detecting projects of bearing can be measured.
Advantage of the present utility model is:
1, realized the function of hand-held instrument.Because basic framework has adopted tubular structure, has effectively alleviated the weight of instrument, has kept due rigidity simultaneously, is achieved hand-held function;
2, measuring principle be according in the existing national standard about the measuring principle of bearing, be the same with common use ground bearing special detection instrument, so measured value also can be equivalent.Normally used bearing special detection instrument is that bearing parts is placed on the instrument, read the numerical value of measured parameter by the swivel bearing part, and the measuring principle of the utility model design is the same with using ground bearing special detection instrument usually, so measured value also can be equivalent, difference is to read the numerical value of measured parameter by rotary apparatus.Particularly when bearing parts was big or heavier, bearing parts had been difficult for moving, and when bearing parts was big especially or heavy especially, bearing parts can't be moved, and common bearing special testing instrument can't use.Can only use simple and easy measurers such as slide calliper rule, bridge chi, pipe chi to do the measurement of dimensional accuracy, these measurer repeatable accuracys are not high, so measuring accuracy is not high.These measurers can't be measured the accuracy of form and position simultaneously.And advantage of the present utility model will fully show;
3, adjustment is easy to use;
4, can realize the measurement of multiple test item.
