Abstract
The utility model relates to a device for measuring the diameter of a shaft disk like workpiece with a large diameter, composed of distance measuring sensor (1), a measuring mechanism (2) and a measuring control and data processing device (3). The measuring mechanism (2) is composed of a measuring rule (21), four auxiliary wheels (22), two positioning shafts (23), a positioning magnet (24) and a connecting rod (25). The utility model has the advantages of non-contact type measurement, in-line type measurement in processing workshops, off-line type measurement in installing fields and high measuring precision, measuring results are automatically displayed, are outputted through voice and are printed on a printer, and the utility model can carry out the size off-normal alarm.
Description
The utility model relates to a kind of measurement mechanism of major diameter shaft-disc-like diameter of work.
In the prior art, the measurement of major diameter shaft-disc-like diameter of work is paid close attention to by people always, slide calliper rule, milscale, gauge or the employing roller mensuration measuring instruments of adopting more, exist heavy, time-consuming and problem such as measuring error is bigger, the roller method also can cause certain scratch to the machined surface of workpiece.Also has a kind of method (patent No.: ZL92226317.5) that adopts non-cpntact measurement, this method needs at surface of the work measurement markers to be set, utilize the rotation of workpiece to measure, only be applicable to online measurement, for transporting out of the workshop after the processing, and during the offline mode of installing at the construction field (site), then can't measure.
The purpose of this utility model provides a kind ofly not only to be measured applicable to online measurement but also applicable to off-line type, and the measurement mechanism of the high major diameter shaft-disc-like diameter of work of measuring accuracy.
The purpose of this utility model is achieved by the following scheme:
The measurement mechanism of major diameter shaft-disc-like diameter of work is made up of with data processor (3) distance measuring sensor (1), measuring mechanism (2) and measurement control.Measuring mechanism (2) is made up of dip stick (21), four auxiliary wheels (22), two locating shafts (23), phase magnet (24) and connecting rod (25).Distance measuring sensor (1) is contained in the midpoint of dip stick (21).
The utlity model has non-contact measurement, not only can carry out online measurement but also can carry out off-line type in the erecting stage and measure and the high advantage of measuring accuracy in job shop.

Embodiment:
As shown in Figure 1, the auxiliary wheel (22) that measuring method of the present utility model is based on and on the surface of large-diameter workpiece (4) two known radius is set is r, the centre distance L of two auxiliary wheels (22) is a known set, measure the mid point of two auxiliary wheels (22) circle center line connecting and surface of the work apart from x, and then according to formula:
D=(L
2/ 4 (r-x))-(r+x) obtain diameter of work D.Shown in Fig. 2,3, the measurement mechanism of major diameter shaft-disc-like diameter of work is made up of with data processor (3) distance measuring sensor (1), measuring mechanism (2) and measurement control.Measuring mechanism (2) is made up of dip stick (21), four auxiliary wheels (22), two locating shafts (23), phase magnet (24) and connecting rod (25).Two locating shafts (23) are contained in the two ends of dip stick (21) respectively, auxiliary wheel (22) is installed at two ends at two locating shafts (23), guarantee during assembling that parallel to each other and distance axial line of two locating shafts (23) is known length L, the radius of auxiliary wheel (22) is r.Two connecting rods (25) are contained in the outside of locating shaft (23) at the two ends of dip stick (21) respectively.Phase magnet (24) is contained in the lower end of two connecting rods (25), which is provided with handle (26).Distance measuring sensor (1) is contained in the midpoint of dip stick (21), and this point equates with the distance of two locating shafts (23).The lead-in wire of distance measuring sensor (1) is connected with data processor (3) with measuring to control.As shown in Figure 4, measure control and comprise that with data processor (3) signal amplifies and reshaper (31), single-chip microcomputer (32), display (33), phonetic synthesis acoustical generator (34) and printer (35).
During measurement, the measuring mechanism (2) of measurement mechanism is placed on (as surveying external diameter is outside surface on the measured surface of workpiece (4), as to survey internal diameter be inside surface), four auxiliary wheels (22) are all contacted with measured surface, pull handle (26) and phase magnet (24) is fallen be adsorbed on the measured workpiece (4), thereby measurement mechanism and measured workpiece are fixed.
At first send measuring-signal by measuring the single-chip microcomputer (32) of control with data processor (3), control distance measuring sensor (1) carries out continuous automatic measurement, thereby draw the vertical signal apart from x of one group of center (i.e. the mid point of the vertical range of the axial line of two locating shafts (23)) to the measured workpiece surface by dip stick (21), the signal that at every turn records amplifies with reshaper (31) by signal to be handled, and enters automatically in the single-chip microcomputer (32) as data.Measure control and the single-chip microcomputer (32) of data processor (3) and receive last group data, just enter data handling procedure automatically from distance measuring sensor (1), according to formula:
D=(L
2/ 4 (r-x))-and (r+x) calculating, result of calculation D is the diameter of measured workpiece.The value of D shows by display (33) as a result, by phonetic synthesis acoustical generator (34) output, also can go up at printer (35) and print, and can carry out the size warning of crossing the border.
