Fig. 2 is the C-C cut-open view of Fig. 1.
Fig. 3 is the B-B cut-open view of Fig. 1.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
Such as Fig. 1～shown in Figure 3: the present invention mainly is comprised of folder dial gauge 1, latch segment 2, tong-test ammeter cover 3, upper regulator 4, screw 5, lower guage body 6, screw 7, chaining pin 8, lever 9, stop screw 10, extension rod 11, the first Compress Spring 12, split washer 13, stop screw 14, spacer pin 15, button 16, the second Compress Spring 17, pin 18, push rod 19, the 3rd Compress Spring 20 etc.
Undercut groove axial depth measuring mechanism of the present invention, described upper end in upper regulator 4 are press-fitted tong-test ammeter cover 3, by the fixing dial gauge 1 of latch segment 2.Dial gauge 1 head is equipped with extension rod 11, and extension rod 11 is provided with split washer 13, the first Compress Spring 12, the first Compress Springs 12 is housed on the split washer acts on the split washer 13.Lever 9 is contained in regulator 4 lower ends, and described lever 9 and upper regulator 4 clearance fit with pin 18 clearance fit, rotate around pin 18.Described lever 9 contacts with extension rod 11 by the steel ball that press fit in the lever 9.Chaining pin 8 is equipped with in lever 9 lower ends, clamps by screw 7.Upper regulator 4 is connected by screw 5 with lower guage body 6.Stop screw 14 and button 16 are equipped with in lower guage body 6 upper ends, and the 2nd Compress Spring 17 is housed behind the button, and button 16 is limited in lower guage body 6 interior activities by spacer pin 15, and Compress Spring acts on the button 16.There are 19, two push rods of two push rods 19 lower guage body 6 lower ends by stop screw 10, are limited in lower guage body 6 interior activities.The 3rd Compress Spring 20 is housed behind two push rods 19, and push rod 19 is limited in the lower guage body 6 by stop screw.
Described tong-test ammeter cover 3 is contained in upper regulator 4 by interference fit.Upper regulator 4 and lever 9 are by clearance fit, and tolerance clearance is less, and purpose is rocking of control lever 9, and lever 9 rotates around pin 18.It is to adjust the scope of activities of lever 9 that stop screw 14 purposes are equipped with in lower guage body 6 upper ends.It is to withstand lever 9 that button 16 purposes are equipped with in lower guage body 6 upper ends, conveniently gauge is inserted in the workpiece, and described button and lower guage body are clearance fit.As shown in Figure 4, push rod 19 is equipped with in lower guage body 6 lower ends, and purpose is to promote gauge to be adjacent to workpiece to a direction when work, is convenient to measure.
Principle of work of the present invention and the course of work:
Measuring state, release button 16, button 16 resets under the Compress Spring effect.Thereby the lower split washer 13 that promotes of Compress Spring 12 effect promotes extension rods 11, and extension rod 11 moves downward force transmission to lever 9, and lever 9 rotates around pin 18, and the chaining pin 8 on the lever 9 contacts with workpiece.
The recovery state, press push button 16 overcomes the acting force of the first Compress Spring 12, and lever 9 is upwards lifted, and lever 9 rotates around pin 18, and the chaining pin 8 on the lever 9 breaks away from workpiece, at this moment whole gauge can be taken out or insert workpiece from workpiece.
In school zero, at first then press push button 16 is placed on whole gauge in the calibrating device, release button 16, and chaining pin 8 ejects, and by lever 9 and extension rod 11 the axial depth variable quantity is passed, with the numerical value zeroing that shows.
After finish in school zero, just can measure workpiece with same procedure, the numerical value that surveying instrument shows is exactly that the undercut groove axial depth is with respect to the variable quantity of calibrating device.
