【Utility model content】
The in-site measurement of diameter height is determined for solution, the utility model devises a kind of lock pin and determines diameter height measurement inspection
Tool, the detection method has important directive significance to same type size detection with testing fixture design.
To achieve the above object, the utility model uses following technical scheme：
A kind of lock pin determines diameter height measurement cubing, including bottom plate, swivel nut, guide pin bushing and axle sleeve, described swivel nut top
Jam nut is threaded with, axle sleeve is set in swivel nut upper end；Guide pin bushing one end is stretched into inside swivel nut, and the other end passes through spring and axle sleeve
Cavity top contact；It is provided with the top of axle sleeve at the top of dial gauge, the gauge head contact guide pin bushing of dial gauge；During measurement, lock pin or mark
The bottom of quasi- part is arranged in the through hole on bottom plate, and swivel nut is enclosed on lock pin or standard component, the upper end of lock pin or standard component
Stretch into inside guide pin bushing；Described guide pin bushing bottom matches and contacted with the conical surface of standard component.
Via depth on described bottom plate is more than the bottom length of lock pin or standard component.
Described swivel nut internal diameter matches with lock pin or standard component mid diameter, guide pin bushing external diameter.
The cavity depth of described guide pin bushing is more than the upper end level of lock pin or standard component.
The bushing of described dial gauge is arranged in axle sleeve top mounting holes, and fixed by holding screw.
Described jam nut is locking nut, mainly prevents swivel nut from being loosened with axle sleeve.
The inner conical surface taper of described guide pin bushing bottom is 35 °.
The utility model compared with prior art, with advantages below：
The utility model constitutes fixing and limiting structure by bottom plate, swivel nut, guide pin bushing and axle sleeve, by the gauge head of dial gauge with leading
Top contact transmission metrical information is covered, standard component is first passed through and is returned to zero, then lock pin is actual to determine diameter height by measuring
Read dial gauge measurement data, looked into limit error, then be judged as it is unqualified, otherwise it is qualified.The measurement device is accurate, quick,
Measurement efficiency is greatly improved.By practical proof, using the cubing detection efficiency effectively lifting 95%, live survey in real time is realized
Amount, detection method is simple, effective, direct, and scene can adjust lathe parameter in time, for part high-volume processing On-line Control chi
It is very little to provide strong guarantee, achieve direct economic benefit.
Further, swivel nut internal diameter matches with lock pin or standard component mid diameter, guide pin bushing external diameter, and actual measurement was installed
Journey avoids that gap is excessive to rock the error caused.
Further, axle sleeve is threadedly attached on swivel nut, and axle sleeve and swivel nut pine are further prevented by locking jam nut
It is dynamic so that guide pin bushing will not slide inside axle sleeve, it is possible to achieve first assemble and measure afterwards, improve efficiency.

【Embodiment】
The utility model is described in detail below in conjunction with the accompanying drawings：
As shown in Figures 2 and 3, the utility model devise lock pin determine diameter height measurement cubing.Including bottom plate 1, spiral shell
Set 3, guide pin bushing 5 and axle sleeve 6, the described top of swivel nut 3 are threaded with jam nut 4, and axle sleeve 6 is set in the upper end of swivel nut 3；Guide pin bushing 5
One end is stretched into inside swivel nut 3, and the other end passes through spring 7 and the cavity top contact of axle sleeve 6；The top of axle sleeve 6 is provided with dial gauge 10,
The top of gauge head contact guide pin bushing 5 of dial gauge 10；During measurement, the bottom of lock pin or standard component 2 is arranged on the through hole on bottom plate 1
Interior, swivel nut 3 is enclosed on lock pin or standard component 2, and the upper end of lock pin or standard component 2 is stretched into inside guide pin bushing 5；Described guide pin bushing 5
Bottom matches and contacted with the conical surface of standard component 2.
