Description
Technical field
The utility model is related to a kind of detection device of thickness of workpiece, the bottom ends of more particularly to a kind of groove on workpiece
The device that the wall thickness at place measures.
Background technology
When being measured to work grooves bottom end wall thickness, the measurer of use is usually vernier caliper and outside micrometer,
But the measuring jaw of vernier caliper can only measure plane, and outside micrometer gage button is plane, can not also touch the bottom of groove.It is existing
What is had can measure size 1.50-0.2 various survey tools of range, exist and fathom the problem of inadequate, such as make measurement deep
Degree is more than 38 millimeters, it is necessary to existing measurer is improved, and the measurer for meeting above-mentioned condition only has outside micrometer, needs
The position of restructuring is at the ruler frame and gage button two of outside micrometer.Outside micrometer is according to made of worm drive principle, is divided
Distinguish to be 0.01-0.001 millimeters, measurement accuracy is very high, and the especially some effects such as ruler frame, micrometric screw, gage button are smart to measuring
Degree.How the accurate measurement of groove is completed using existing outside micrometer, and do not damage micrometer, it is badly in need of in Site Detection
It solves the problems, such as.
Invention content
The utility model provides a kind of outside micrometer of detectable work grooves bottom end wall thickness, solves depth and is more than
The measurement problem of 38 millimeters of groove base end wall thickness.
The utility model is to solve more than technical problem by the following technical programs：
A kind of outside micrometer of detectable work grooves bottom end wall thickness, including micrometer gage button, band groove workpiece and survey
Micro- screw rod, movable sleeve is connected to bearing sleeve on micrometer gage button, is connected in bearing sleeve and lengthens tip measuring rod, added
Band groove workpiece is provided between long tip measuring rod and micrometric screw, lengthens the tip apical grafting of tip measuring rod in band groove work
On the groove bottom end medial surface of part, the end apical grafting of micrometric screw is on the bottom surface with groove workpiece.
The outer diameter of micrometer gage button is identical with lengthening the outer diameter of tip measuring rod.
The utility model does not damage the original measurer for measuring characteristic and self structure, taking full advantage of micrometer itself of measurer
Precision measures size accurately, has certain versatility, can measure variously-shaped groove and plate-like class product, concave are thin
Wall pieces etc.；Bearing sleeve and lengthening tip measuring rod can use on the micrometer of different range abilities, and interchangeability is good.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of outside micrometer of detectable work grooves bottom end wall thickness, including micrometer gage button 1,4 and of band groove workpiece
Micrometric screw 5, movable sleeve is connected to bearing sleeve 2 on micrometer gage button 1, is connected in bearing sleeve 2 and lengthens tip measurement
Bar 3 is provided with band groove workpiece 4 lengthening, lengthens the tip top of tip measuring rod 3 between tip measuring rod 3 and micrometric screw 5
It is connected on the groove bottom end medial surface with groove workpiece 4, the end apical grafting of micrometric screw 5 is on the bottom surface with groove workpiece 4.
The outer diameter of micrometer gage button 1 is identical with lengthening the outer diameter of tip measuring rod 3；Locking machine on outside micrometer
Structure 6, fixed sleeving 7 and microdrum 8 remain unchanged.
Measurement range is 50-75 millimeters of outside micrometer, and it is 50 millimeters that its minimum, which measures size, such as measure size for
1.5 millimeters, it is necessary to increase by one and lengthen tip measuring rod 3, minimum length is 50 millimeters；Lengthen the outer diameter of tip measuring rod 3
Consistent with the outer diameter of micrometer gage button 1, one end is contacted for plane with micrometer gage button, and the other end needs to make according to measuring point
Into different shape, such as conical, trapezoidal, U-shaped, cone angle is made as 60 degree of cones according to arc groove；Micrometer gage button 1 is
It is fixed on ruler frame, can not take out, need to make a quill, be socketed on gage button, point is lengthened for supporting and fixing
Head measuring rod, can make stairstepping, endoporus is through-hole, and diameter is consistent with gage button, hole according to the specification of micrometer by bearing sleeve 2
It is gap-matched with axis.
Outside micrometer is first subjected to zero adjustment with check and correction gauge rod, retaining mechanism 6 is unclamped, rotates microdrum 8, make measurement
Distance is more than 50 millimeters；The plane one end for lengthening tip measuring rod 3 is put into bearing sleeve 2, then, by bearing sleeve 2
Big end is inserted into micrometer gage button, and end face is made tightly to be bonded with ruler frame end face；Microdrum 8 is rotated, makes micrometric screw 5 with lengthening point
Head measuring rod 3 is contacted to zero, the zero curve on microdrum 8 with the datum line on fixed sleeving 7 point-blank；It, will during measurement
Two measuring surface of micrometer by the measuring method of micrometer with after tested location contacts, being measured and direct reading.
