Abstract
The invention discloses a pair of integrated double calipers, which is a size measuring tool. Two caliper legs of the integrated double calipers are rotatablely connected through a rotating shaft and are fixed by an outer washer in the axial direction. Each caliper leg is in the shape of outside calipers on one side of the rotating shaft and is in the shape of inside calipers on the other side of the rotating shaft; one side of the assembled calipers is used as the outside calipers, and the other side of the assembled calipers is used as the inside calipers; measuring points at two ends of each caliper leg of the calipers are collinear with the center of the rotating shaft on the middle part to guarantee that the positions of zero sizes for measuring at the two ends of the calipers are the same; and meanwhile, the distances from the measuring points at the two ends of the caliper legs to the center of the rotating shaft are equal or in multiple relationship to guarantee determination relationship of detection size of the measuring points of the inside calipers and the detection size of the measuring points of the outside calipers. The pair of integrated double calipers has the functions of the inside calipers and the outside calipers and is convenient to carry and manage on a surveying and mapping field; particularly, the size of an internal large surface of a part can be more conveniently detected by directly utilizing the inside calipers; and meanwhile, the pair of integrated calipers is easy to manufacture and low in cost.
Description
Technical field
The present invention relates to a kind of survey instrument that integrates internal calliper and external callipers function.
Background technology
Inside and outside clamp all are simple survey instruments.External callipers is used for measuring external diameter and surface, and internal calliper is used for measuring internal diameter and groove.At present, inside and outside clamp are to use separately, usually need the two to have both in measure field.And when using internal calliper to measure the size on the inner big surface of part, pass through the less surface of part side dimension, not by additive method, use internal calliper to measure separately.
Summary of the invention
The present invention provides a kind of integral type hermaphrodite caliper that integrates internal calliper and external callipers function, is convenient to carrying and managing of clamp, and it can overcome the shortcoming that independent use internal calliper can't be measured the inner big surface size of part simultaneously.
The technical scheme that the present invention adopts is: a kind of integral type hermaphrodite caliper, and it comprises pincers leg, rotating shaft and packing ring, said pincers leg has two; Article two, said pincers leg all has external callipers leg, turntable structure and internal calliper leg; Said external callipers leg and said internal calliper leg lay respectively at the both sides of said turntable structure, and the middle part of said turntable structure is provided with circular hole, and said rotating shaft is passed said circular hole so that two said pincers leg correspondences are linked together; Be separately installed with a said packing ring in the outside of two said pincers legs; And said packing ring is fixed in the said rotating shaft, can relatively rotate to guarantee two said pincers legs, thereby measure.
Two said pincers legs also have external callipers leg measurement point and internal calliper leg measurement point respectively, and the center conllinear of the said external callipers leg measurement point of each said pincers leg, said internal calliper leg measurement point and said circular hole.
The distance of said pincers leg external callipers leg measurement point to the distance at the center of said circular hole and internal calliper leg measurement point to the center of said circular hole equates that perhaps multiple concerns each other.When measuring the inner big surface size of part with the internal calliper leg, will not take out by clamp, the distance of directly measuring between other end external callipers leg measurement point gets final product.
The invention has the beneficial effects as follows; The integral type hermaphrodite caliper possesses the function of internal calliper and two kinds of clamp of external callipers; Be convenient to survey and draw on-the-spot carrying and manage; Especially can directly detect the size on the inner big surface of part eaily, integral type hermaphrodite caliper processing and manufacturing simultaneously is easy, with low cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is an integral type hermaphrodite caliper planimetric map.
Fig. 2 is integral type hermaphrodite caliper STRUCTURE DECOMPOSITION figure.
Fig. 3 is that the integral type hermaphrodite caliper is measured the inner large scale of part surface enforcement illustration.
1 pincers leg among the figure, 2 rotating shafts, 3 packing rings.
Embodiment
In Fig. 1 and Fig. 2, the integral type clamp are made up of with rotating shaft 2 and two identical packing rings 3 two identical pincers legs 1.Article two, the pincers leg all has external callipers leg, turntable structure and internal calliper leg; As shown in the figure, external callipers leg and internal calliper leg lay respectively at the both sides of said turntable structure, and the middle part of turntable structure is provided with circular hole; Rotating shaft 2 is passed circular hole and is stretched out outside two pincers legs; Be separately installed with a packing ring 3 in the outside of two said pincers legs, and two packing rings 3 are separately fixed on the outer end of rotating shaft 2, two pincers legs 1 are compressed and correspondence links together; Guarantee that simultaneously two pincers legs 1 can relatively rotate, thereby measure.
Two said pincers legs also have external callipers leg measurement point B and internal calliper leg measurement point A respectively, and internal calliper leg measurement point A is arranged on the outside place, tip of internal calliper leg, so that a side at internal calliper leg place plays the effect of internal calliper, is used to measure internal diameter and groove; External callipers leg measurement point B is arranged on the inside place, tip of external callipers leg, so that the external callipers leg belongs to the effect that a side plays external callipers, is used to measure external diameter and surface.On each bar pincers leg, the circular hole center conllinear at internal calliper leg measurement point A, external callipers leg measurement point B and clamp middle part is identical to guarantee clamp two-sided measurement zero size positions.
In the embodiment shown in fig. 3, two-dot chain line is depicted as tested part.When accuracy requirement was not high, dimension D can be directly with the internal calliper leg measurement point A detection of clamp, after promptly internal calliper leg measurement point A contacts measured surface; Needn't take out; But directly detect the size d between external callipers leg measurement point B, if internal calliper leg measurement point A measurement point equals external callipers leg measurement point B to circular hole centre distance, then D=d to the distance at the center of the circular hole at middle part; If the distance at A measurement point circular hole center to the middle part is B measurement point n times to circular hole centre distance, then D=nd.For the ease of user's measurements and calculations, can indicate the numerical value of n on the surface of clamp pincers leg, general round numbers is calculated to simplify.
