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) clinometer rule (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).Clinometer rule (1) comprises stepper motor (11), variator (12), fork (13) and displacement transducer (14), displacement transducer (14) is contained on the fork (13), fork (13) is installed in the locating shaft (23) of measuring mechanism (2) one sides and locates, and its swinging center is by the center of locating shaft (23).
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 the measuring method of major diameter shaft-disc-like diameter of work 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 line in two auxiliary wheels (22) center of circle and the angle x of auxiliary wheel (22) center and workpiece centre line, and then according to formula:
D=(L/cos x)-2r obtains 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) clinometer rule (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).Clinometer rule (1) comprises stepper motor (11), variator (12), fork (13) and displacement transducer (14), displacement transducer (14) is contained on the fork (13), fork (13) is installed in the locating shaft (23) of measuring mechanism (2) one surveys and locates, and its swinging center is by the center of locating shaft (23).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).The control signal of stepper motor (11) is provided by single-chip microcomputer (32), and amplification is connected with reshaper (31) lead-in wire of displacement transducer (14) with signal.
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 step motor (11) is started working, stepper motor (11) uniform rotation, thereby driving fork (13) by variator (12) at the uniform velocity swings, control bit displacement sensor (14) carries out continuous automatic measurement simultaneously, draw one group from the axle center of locating shaft (23) distance signal to the measured workpiece surface, 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.In the process that fork (13) is at the uniform velocity swung, find out the minor increment that displacement transducer (14) is measured, the pairing point of minor increment is the point of contact of auxiliary wheel (22) and workpiece (4).Because fork (13) at the uniform velocity swings, therefore utilize fork (13) the used time of swing can obtain the angle x of two auxiliary wheel (22) circle center line connectings and auxiliary wheel (22) center and workpiece centre line, and then according to formula:
D=(L/cos x)-2r calculates, and 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.
