Abstract
The utility model provides an inside caliper belongs to one type on machining measuring tool commonly used, has overcome the prior art calliper in the great problem of measurement process error of mean square. Its structure contains: arc fixed bolster 1, spring 2, screw rod 3, handle 4, set nut 5, masuring jaw 6, masuring jaw 6, arc support 1 rivet connection: handle 4 and arc support 1 welded connection: screw rod 3 is connected with spring 2, set nut 5, screw rod 3 passes 6 claw waist position swing joint of masuring jaw, and spring 2 is in two masuring jaws, 6 centres, masuring jaw 6 is convex, claw point position slabbing. These calliper simple structure, the simple operation, it is accurate to measure, low cost, the range of application is wide.
Description
Technical field
This utility model belongs to measurer one class that machining is conventional.
Background technology
In the parts measurement work of machining scene, have some parts physical dimension due to by special form
Shape impact, and less demanding for its scale error of the drawing of parts own, and conventional survey tool such as vernier
Slide calliper rule, straight steel ruler, tape measure etc. cannot be carried out measuring, and inside plain calipers must be used to measure.But the inside plain calipers of prior art is being measured
Time measuring jaw between not location to measurement size, affected relatively big by external force, its measurement size error rate is bigger.
Summary of the invention
The purpose of this utility model is to overcome prior art clamp bigger problem of error during measuring.
A kind of inside plain calipers, its structure contains: arc fixed support 1, spring 2, screw rod 3, handle 4, location nut 5, measuring jaw
6；Described measuring jaw 6, arc fixed support 1 rivet interlacement: handle 4 is welded to connect with arc support 1: screw rod 3 and spring 2, fixed
Position nut 5 connects；Screw rod 3 is flexibly connected through measuring jaw 6 pawl loin, and spring 2 is in the middle of two measuring jaws 6；Described measuring jaw 6 is round
Arc, hook tip position slabbing.
The advantage of these clamp is: simple in construction, simple operation, measures accurately, with low cost, applied range.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and working method schematic diagram,
In figure: 1 arc fixed support, 2 springs, 3 screw rods, 4 handles, 5 location nut, 6 measuring jaws, 7 workpiece.
Detailed description of the invention
A kind of clamp, its structure has: arc fixed support 1, spring 2, screw rod 3, handle 4, location spiral shell
Mother 5, measuring jaw 6；Described measuring jaw 6, arc support 1 rivet interlacement: handle 4 is welded to connect with arc support 1: screw rod 3 and spring
2, location nut 5 connects, and screw rod 3 is flexibly connected through measuring jaw 6 pawl loin, and spring 2 is in the middle of two measuring jaws 6；Described measuring jaw 6
Being circular arc, hook tip position slabbing, angle of nip is the top of two measuring jaws.
Workpiece 7 endoporus groove is as measurand.Pawl point and workpiece 7 inner hole wall point cantact when measuring jaw 6 measures aperture, pawl
Will not collide with hole wall and interfere in both sides.
Using method:
1. all parts debugging these clamp is the most intact, and movable normal.
2. workpiece 7 internal diameter measured by inside plain calipers, first adjusts measuring jaw 6 aperture of inside plain calipers, sees the internal diameter size of measured part
Whether in the range of the measurement of these clamp.
The two of clamp measuring jaws 6 the most first are tightened to easily to enter with hands the size of workpiece 7 endoporus, put endoporus into, use
The thumb of left hand and forefinger grapple the bottom card base of two card bases, and the elastic force by spring 2 makes it open, and should make the survey of two angle of nips
The on line in amount face is just vertically intersected on the two-end-point that two measuring surface of the axis of endoporus, i.e. angle of nip should be diameter of bore.
4. the measuring surface of following angle of nip should be parked on workpiece 7 inner hole wall when measuring as fulcrum, angle of nip above to
Aperture is the most outwards soundd out, and along hole wall circumferencial direction swing, when can swing along hole wall circumferencial direction away from
From for time minimum, then it represents that two measuring surface at inside plain calipers angle have been in the two-end-point of diameter of bore, then will location nut 5
It is locked to this position.
5. tighten up two claws with hands, gently clamp are removed, it is to avoid collide with the inwall in aperture；The most afterwards by clamp amount
Pawl unclamps gently, and now behind location, distance between two angle of nips is exactly the internal diameter size in measured aperture.
6. it should be noted that several aspect when measuring:
Inside plain calipers tightness in hole in piece part is compared when a. measuring.As inside plain calipers has bigger freely swinging in hole
Time, mean that caliper size is less than internal orifice dimension；
B. it is not placed into such as inside plain calipers, or puts into after in hole so the tightest that can not to freely swing, mean that inside plain calipers size compares aperture
Big；
C. hole put into by inside plain calipers, can have the distance that freely swings of 1～2mm, at this moment aperture according to above-mentioned measuring method
The most equal with inside plain calipers size；
D. measure time do not hold clamp measuring jaw measure, such feel just without, it is difficult to compare inside plain calipers zero
Tightness in piece bores, and make clamp deformation produce measurement error.
These clamp are owing to being the opening and closing using spring regulation measuring jaw, by the nut location to measurement size, location, thus right
Measurement result impact is little.
