Offer pilot hole on the described measurement shank, putting on the shelf at base plate is provided with the guide pole that stretches in the pilot hole.
Offer pilot hole on the described measurement shank, putting on the shelf at base plate is provided with the guide pole that stretches in the pilot hole.
Described base plate two ends bottom face is respectively equipped with second reference block and first reference block, and stretch out in the datum hole of second reference block first bottom of measuring shank, and stretch out in the datum hole of first reference block second bottom of measuring shank.Described base plate upper surface is provided with handle.
The present invention is simple, compact and reasonable for structure; The center in two holes can be located fast, and bearing accuracy can be improved; Can make checkout equipment can check more high-grade size; Measure easyly, quick, can when guaranteeing measuring accuracy, increase work efficiency greatly.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present invention.
Fig. 2 is the A-A cut-open view of Fig. 1.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 2: the present invention is mainly measured shank 4, guide pole 5, endoporus 6 is installed, pilot hole 7, handle 8, base plate 9, first reference block 10, chute 11, endoporus 12, measuring head 13, datum hole 14, cover plate 15, guide rail 16, datum hole 17, handle 18, slide block 19, back-moving spring 20, second are installed are measured shank 21, guide pole 22, second guide pin bushing 23, pilot hole 24, second reference block 25 etc. and form by first guide pin bushing 1, plug screw 2, back-moving spring 3, first.
Center distance measurement of the present invention mechanism, comprise base plate 9, hole internal fixation in an end of base plate 9 is provided with first guide pin bushing 1, first guide pin bushing 1 is provided with installs endoporus 6, plug screw 2 spins in the upper end of this installation endoporus 6, the lower end sliding plug of this installation endoporus 6 has first to measure shank 4, the first and measure shanks 4 bottoms and be inverted round platform or coniform and stretch out base plate 9 lower surfaces, is provided with back-moving spring 3 in first endoporus of measuring between shank 4 and the plug screw 2; The other end of base plate 9 offers the chute 11 along its length direction, be provided with the cover plate 15 that covers chute 11 in base plate 9 upper surfaces, cover plate 15 is provided with guide rail 16, slidely connect slide block 19 on the guide rail 16, slide block 19 lower ends connect second guide pin bushing 23 that stretches in the chute 11, second guide pin bushing 23 is provided with installs endoporus 12, the lower end sliding plug that endoporus 12 is installed has second to measure shank 21, second measures shank 21 bottoms is inverted round platform or coniform and stretch out base plate 9 lower surfaces, between the second measurement shank 21 and slide block 19, be provided with back-moving spring 20, on base plate 9, be provided with the measuring head 13 that is against second guide pin bushing, 23 outside wall surface.
As shown in Figure 1, it is clearance fit that first guide pin bushing 1 and first is measured shank 4, and tolerance clearance is less, and purpose is that the radial missing that shank 4 produces when mobile is measured in control first in first guide pin bushing 1; The cooperation of second guide pin bushing 23 and the second measurement shank 21 is the same; The pretightning force of back-moving spring 3 and back-moving spring 20 is wanted and can smoothly register pin be bound to extreme position, when measuring register pin is had certain elastic force, register pin is found can be stuck in the aperture behind the center, hole can not break away from easily; The purpose of mounting knob 8, handle 18 is to make things convenient for personnel's both hands to pick up cubing to operate; The effect of guide pole 5, guide pole 22 is that the moving range that shank 4 and second is measured shank 21 is measured in control first; Comprise some rollers between slide block 19 and the guide rail 16, after guide rail 16 and cover plate 15 were connected and fixed, slide block 19 can move flexibly along the roller direction; Hold out against with screw between guide rail 16 and the slide block 19, slide block 19 is not relatively moved in vertical direction.
The principle of work of the present invention and the course of work:
In work reference block 10 is placed on the calibrating device reference field, first measures shank 4 inserts a hole, when first measure under the screen resilience effect of shank 4 at back-moving spring 3 can not be again in the hole before so that when being stuck in the position, aperture, represent that this hole has been located to finish.Suitably regulate mobile cover plate 15 and make second to measure shank 21 another holes of insertion, block the location equally, two hole centre distance variable quantities pass by measuring head 13, 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 the variable quantity of the relative and calibrating device of centre distance.
