Abstract
The invention provides a link plate hole perpendicularity detecting gauge having convenient use and reliable detection. The link plate hole perpendicularity detecting gauge comprises a gauge body and a gauge pin, wherein the gauge body is at least provided with a plane, and the gauge pin is perpendicularly connected to the plane. The link plate hole perpendicularity detecting gauge has a simple structure, is convenient to use and reliable to detect, and can meet the detection requirements when matched with basic detection tools such as a caliper and a filler gauge.
Description
Technical field
The present invention relates to the testing tool of chain intermediate plate, specifically, is the squareness measuring gauge on chain plate hole and carrier bar surface.
Background technology
At present, along with improving constantly of requirements such as chain product precision, intensity, quality to chain part just seems particularly important, its intermediate plate is as the important component part of chain, playing the part of important role on the performance of chain, its each size, parameter all can exert an influence to the performance of chain.In quality control, often need the verticality on chain plate hole and carrier bar surface be detected, also mainly be to observe but it is detected by eyes.Therefore the verticality for the chain plate hole also lacks the suitable method of inspection and testing tool, and also can't reflect the quality state of the verticality of chain plate hole objectively, thereby cause and go up quality problems such as in time to find, correct carrier bar verticality difference at the scene with data.
Summary of the invention
The purpose of this invention is to provide a kind of easy to use, detect reliable verticality detection gauge for chain-plate hole.
This verticality detection gauge for chain-plate hole, the amount of comprising body and amount post, the amount body has a plane at least, and the amount post is vertically connected on the plane.
To measure during detection that post inserts highly is that measuring pin diameter and carrier bar bore dia match in the chain plate hole of carrier bar of H; The tilt quantity post makes the plane of connection amount post contact with the carrier bar surface to maximum angle (till promptly can not tilting) simultaneously again then.Record the maximal clearance C that forms between the plane of carrier bar surface and the amount of connection post with survey instrument, so the angle a=tan between the surperficial plane with the amount of connection post of carrier bar
-1(C/H), thus calculate angle a '=90-a between chain plate hole and the carrier bar surface.If the maximal value a ' max to the angle a ' between chain plate hole and the carrier bar surface during design has requirement, angle amax=90-a ' the max between carrier bar surface and the gauge edge of a knife face then, we just can instead obtain Cmax=H*tan (90-a ' max) so, whether we just can check the clearance C that forms between carrier bar surface and the gauge edge of a knife face qualified with clearance gauge then, and promptly whether the carrier bar hole perpendicularity is qualified.The present invention is simple in structure, easy to use, detection is reliable, cooperates basic testing tool such as slide calliper rule, clearance gauge just can reach the detection requirement.
As improvement, the plane of described connection amount post is circular, is evenly equipped with four projections at the periphery of circular flat, and the end face of four projections is on the same plane perpendicular to the amount post.For the convenience of narrating, we claim that the end face of four projections is an edge of a knife face.By 4 equally distributed edge of a knife faces, reduction body and carrier bar surface contact area improve measuring accuracy.
As improvement, the amount body is a right cylinder, and the external diameter of amount body is greater than the height of detected carrier bar.
As improvement, described amount post is two different amount posts of diameter, on the both ends of the surface of two the amount post amount of being connected to bodies.Two the different amount of diameter posts can cooperate to detect different carrier bars with the chain plate hole of different-diameter respectively.

Embodiment
Referring to verticality detection gauge for chain-plate hole shown in Fig. 1-3, comprise that external diameter is two different amount posts 1 of diameter of two end faces of cylinder scale of construction body 2 and overhang body of D, in the amount post amount of the being contained in body, and interference fit; Amount post and amount body are coaxial.Periphery on the amount body both ends of the surface respectively is evenly equipped with the end face of 3, four projections of four projections on the same plane (edge of a knife face) 5 perpendicular to the amount post.The outer diameter D of amount body flies height H (be D〉H) greater than carrier bar 4.
Two measuring pin diameter A, B process according to the carrier bar hole dimension.To measure post during detection and insert highly in the chain plate hole for the carrier bar of H, the tilt quantity post be to maximum angle (till promptly can not tilting) again then, makes simultaneously that edge of a knife face and carrier bar are surperficial to contact.Record the maximal clearance C that forms between carrier bar surface and the edge of a knife face with survey instrument, so the angle a=tan between carrier bar surface and the edge of a knife face
-1(C/H), thus calculate angle a '=90-a between chain plate hole and the carrier bar surface; If the maximal value a ' max to the angle a ' between chain plate hole and the carrier bar surface during design has requirement, angle amax=90-a ' the max between carrier bar surface and the edge of a knife face then, we just can instead obtain Cmax=H*tan (90-a ' max) so, whether we just can check the clearance C that forms between carrier bar surface and the gauge edge of a knife face qualified with clearance gauge then, and promptly whether the carrier bar hole perpendicularity is qualified.
By the projection 3 of respectively processing 4 equally distributed formation edge of a knife faces at amount body two ends, reduction body and carrier bar surface contact area improve measuring accuracy.
The present invention only is made of amount body and amount post, and is simple in structure, with low cost, cooperates basic testing tool such as slide calliper rule, clearance gauge just can reach the detection requirement.
