Description
Technical field
The utility model belongs to electronic devices and components checkout equipment technical field, especially relates to a kind of ceramic insertion core length detection frock.
Background technology
Ceramic insertion core is the core parts of the optical communication passive device joints of optical fibre, is widely used in optical communication field.It is cylindric that ceramic insertion core is, and must control its length dimension in the production run, so must examine entirely its length dimension.Usually, the length of ceramic insertion core is less than 10.5MM, and external diameter is 1.5-3.5MM, is the less precision element of size, and the metering system of conventional lengths is the mode that adopts as described in Figure 4 at present: utilize micrometer caliper 12 to measure the length of lock pin.Have shortcoming: this kind measurement is by rotation adjustment knob the both ends of the surface of micrometer caliper to be contacted to measure lock pin length with the lock pin both ends of the surface, and there are two significant disadvantages in this metering system.
1, each position of all wanting the centering workpiece of measuring makes the axle center of workpiece vertical with the both ends of the surface of micrometer caliper so that measurement is more accurate, influences work efficiency.
2, through long-time, the repeatedly measurement of Shuoing, the both ends of the surface that are used for holding out against lock pin will be worn and torn, and cause the result of measurement inaccurate, and this moment, need carry out maintenance process to the both ends of the surface of micrometer caliper, and maintenance difficulty is bigger.
The utility model content
The purpose of this utility model provides a kind of accuracy that can effectively guarantee the ceramic insertion core linear measure longimetry, and the ceramic insertion core length detection frock that can increase work efficiency greatly.
In order to achieve the above object, the utility model is to adopt following structure:
Ceramic insertion core length detection frock, this frock comprises base, the dial gauge holder, sounding rod is fixed, V-type locating piece holder and dial gauge, described dial gauge holder and V-type locating piece holder are fixed on the two ends of described base in opposite directions, described dial gauge holder is provided with mounting hole, fix described sounding rod holder on the described dial gauge holder wall corresponding with this mounting hole, the middle part of this sounding rod holder has cavity, described dial gauge is sleeved in the mounting hole that is provided with on the dial gauge holder and its gauge outfit is inserted in the cavity of described sounding rod holder, being inserted with the cross section in the end of described sounding rod holder is "T"-shaped sounding rod, is provided with spring between the cavity inner wall of this sounding rod and described sounding rod holder; Described V-type locating piece holder is provided with the V-type locating piece, and the described V-type locating piece holder that is positioned at this V-type locating piece outside is provided with gag lever post.
Adopt the said structure key to be: adopted V-type locating piece and removable sounding rod and gag lever post,
1, adopts the fixedly position of lock pin automatic capturing lock pin of V-type locating piece, can measure fast and increase work efficiency.
2, sounding rod and gag lever post all are Replacement Parts, and when wearing and tearing took place its end face, can change it was that economy has guaranteed the accuracy of measuring again.
The utility model very convenient needs that operate are put in workpiece in the V-type locating piece in addition, promote dial gauge and can finish measurement.
Between the mounting hole of described dial gauge holder and described dial gauge, split ring is housed, is provided with screw in described dial gauge holder upper end.
Screw makes it hold the dial gauge gauge outfit tightly by compressing split ring.
Beneficial effect is: measure convenient, as to guarantee measurement when can improve efficiency of measurement accuracy.
