Description
Technical field
The utility model belongs to measuring technique, relates to a kind of multifunction depth chi.
Background technology
Do in real work, can often need measure former hole slot position, measuring method commonly used is mainly precision equipment and measures and general gage measuring.Wherein, mainly through taking some special measuring equipments or accurate observation instrument to measure, its measuring accuracy is high, but generally exists testing process very loaded down with trivial details in the precision equipment measurement, the higher problem that gets of cost.General measurer then structure is simple relatively, and it is comparatively convenient to measure, and is widely used in the measurement of physical length.Like pit gauge, both in linear measure longimetry, served as important role.
The many of prior art only are equipped with straight-plate-type angle gauge head with pit gauge, connect the location through 2 of single faces.See also Fig. 1, it is the many synoptic diagram of measuring with pit gauge of prior art.It can only survey near side (ns) groove position L1, and testing process is simple and efficient, and cost is low, and measuring accuracy is high, but can't measure distal edge groove position L2, requires 100 < Φ D1>20, length range is 300mm, has bigger limitation.
Yet along with development of science and technology; Many high-grade, precision and advanced products are more and more; Quality cost becomes very important problem; And endoporus number of slots amount occupies the larger proportion that shell part is measured, and how to improve groove position measuring accuracy, solves the important topic that measurement requirement diversity and simplified measurement flow process or the like become present research.
The utility model content
The purpose of the utility model is: propose a kind of convenient measurement, multifunction depth chi that measuring accuracy is high.
The technical scheme of the utility model is: a kind of multifunction depth chi, its preceding end-grain cutting has stepped portions, and this stepped portions connects removable L type gauge head through connecting hole.
Said L type gauge head is made up of mutual measuring junction connected vertically and link, and wherein, the measuring junction inside surface is parallel with the outside surface strictness.
The width of said measuring junction is less than the width of link.
The connecting hole of said stepped portions is two threaded holes.
The corresponding threaded hole diameter of position and pit gauge stepped portions screw is greater than the stepped portions screwhole diameter on the link, and is connected with circular groove.
The utility model has the advantages that: the utility model multifunction depth chi adopts two-sided two point measurements, and face contacts, and repeatability is high, and its precision can reach 0.03mm, can satisfy the actual measurement requirement.In addition, measuring process is quick, can directly survey and read near side (ns) groove position, and can obtain distal edge groove position through calculating, and can realize expanding measurement range through changing gauge head, and it can measure bottom outlet greater than 10mm, the measurer that the big 0.2mm of bottom land boring ratio bottom outlet is above.Simultaneously, can measure the size of endoporus, cylindrical step, chamfering groove and straight trough near side (ns) groove position, distal edge groove position, low to the requirement of rooved face roughness, applied range has bigger actual application value.

Embodiment
Explain further details in the face of the utility model down.
See also Fig. 2, it is the front-end view of the utility model pit gauge.The preceding end-grain cutting of said pit gauge has stepped portions, and this stepped portions is provided with two vertical connecting holes, is generally threaded hole.In this embodiment, the stepped portions of said pit gauge and screw machining precision are high, wherein; This stepped portions length dimension is 13.0mm, thickness 3.8mm, half the less than pit gauge (pit gauge thickness 8.5mm); The diameter in two holes is 2.5mm, and the center is at a distance of 5.00mm.
See also Fig. 3 and Fig. 4, wherein, Fig. 3 is the side view of pit gauge, and Fig. 4 is its A-A cut-open view.Said gauge head is made up of with link 7 orthogonal measuring junction 6, and the two crotch structure that meets at right angles becomes the L type.The long 9.0mm of this measuring junction, wide 2.0mm, the long 12.7mm of link, wide 4.0mm.In addition, link is provided with position and the corresponding threaded hole of pit gauge stepped portions screw, but this threaded hole diameter is 2.6mm, also has the circular groove of diameter 3.5mm simultaneously.During measurement, the inside surface of said measuring junction will with the seamless applying of measurer reference field, measuring junction outside surface and tested part are fitted, it is strict parallel with outside surface that measuring junction gets inside surface, with the assurance precision.
During actual the use, gauge head is locked on the pit gauge stepped portions through screw.See also Fig. 5, it is the use synoptic diagram of the utility model pit gauge.After gauge head is locked in the pit gauge stepped portions through screw 3, earlier the measuring junction crotch is put into the groove of tested part 1, measuring junction 2 inside surfaces are fitted in a side in the groove, and attention must not be tilted.Then pit gauge 4 blades are pushed or pull on the end face that measurement face (outside surface of measuring junction) until the chi frame is fitted in the tested degree of depth of workpiece and contact with tested deep feel; (which is two-sided to realize two-sided two point locations; Preferably describe clear at which 2), get final product reading this moment.
In addition, the gauge head material of the utility model pit gauge adopts qualitative higher tool steel CrWMn, and through thermal treatment HRC＞57, therefore not yielding, reliability is good.And owing to adopt two-sided two point measurements, face contacts, and repeatability is high, and its precision can reach 0.03mm, can satisfy the actual measurement requirement.In addition, measuring process is quick, can directly survey and read near side (ns) groove position, and can obtain distal edge groove position through calculating, and can realize expanding measurement range through changing gauge head, and it can measure bottom outlet greater than 10mm, the measurer that the big 0.2mm of bottom land boring ratio bottom outlet is above.Simultaneously, can measure the size of endoporus, cylindrical step, chamfering groove and straight trough near side (ns) groove position, distal edge groove position, low to the requirement of rooved face roughness, applied range has bigger actual application value.
