Detailed description of the invention
This utility model utilizes floating diclinic to carve clearance measurement principle, and measurement portion includes the measurement wedge 1 on two band inclined-planes
With calibration wedge 2, according to range and accuracy of detection needs, measure wedge 1 and become certain difference, i.e. with calibration wedge 2 angle design
Measure wedge 1 different with the bevel angle of calibration wedge 2, preferably measure the angle angle less than calibration wedge 2 of wedge 1.Dynamic
Measuring mechanism 5 is fixed on base 6, dynamic hollow and have the sliding sleeve slided for flute profile slide rail 3 between measuring mechanism 5 and base 6
Structure, flute profile slide rail 3 can slide in shift sleeve structure, and flute profile slide rail 3 is affixed with measurement wedge 1, and calibration wedge 2 is fixed on sliding sleeve
Structure, the bottom surface measuring wedge 1 and calibration wedge 2 is generally aligned in the same plane, and flute profile slide rail 3 sets towards the side of dynamic measuring mechanism 5
There is location survey measuring mechanism 4 with matching.For convenience of operation, flute profile slide rail 3 other end also stretches out shift sleeve structure, and this end slot shape
It is fixed with handle on slide rail 3, both can serve as spacing, also can conveniently operate.
By cooperating of dynamic measuring mechanism 5 and location survey measuring mechanism 4, the displacement readings measuring wedge 1 can be read, dynamic
Measuring mechanism 5 and location survey measuring mechanism 4 can use following two embodiment:
Embodiment 1, location survey measuring mechanism 4 are the displacement transducer fixed grid for detecting shift value, and dynamic measuring mechanism 5 is detection
The moving grid of shift value and digital display device, moving grid output is relative to the shift length of fixed grid, and it is aobvious to output signal to digital display device
Show, thus shown measured gap length by digital display device；
Embodiment 2, location survey measuring mechanism 4 are scale with a scale, and dynamic measuring mechanism 5 is vernier, can be containing carving on vernier
Degree.Different with the bevel angle of calibration wedge 2 owing to measuring wedge 1, insert gap length different, measure wedge 1 and carve with calibration
There is relative displacement in block 2, relative displacement is proportional with gap width, by vernier position on scale, it is thus achieved that tested
The gap length of amount.
For guaranteeing the reliability that device operates, measure wedge 1 and calibration wedge 2 contact (can relative displacement), it is possible to
Adapt to narrower clearance measurement, the most also there is the effect of guide and limit；Calibration wedge 2 one end has guide rod, flute profile
Being provided with the chute matched with guide rod in slide rail 3, guide rod is affixed with dynamic measuring mechanism 5 or base 6, can be further by guide rod
Limit calibration wedge 2 and keep straight-line displacement, between the shift sleeve structure that flute profile slide rail 3 and dynamic measuring mechanism 5 and base 6 are constituted simultaneously
Also there is straight-line guidance effect, so that it is guaranteed that the movement locus of two wedge, improve certainty of measurement.
In gap measuring apparatus, the most advanced and sophisticated angle measuring wedge 1 is α 1, and the most advanced and sophisticated angle of calibration wedge 2 is α 2, location survey amount
Relative displacement when mechanism 4 and dynamic measuring mechanism 5 are measured is Y, the most measured gap H:H=K*Y, wherein K=1/tan α 1-
1/tanα2。
During measurement, measure wedge 1 and calibration wedge 2 is all inserted into gap, until measuring wedge 1 and the inclined-plane of calibration wedge 2
All fit the end face edge line in gap, measure wedge 1 and calibration wedge 2 phase para-position by electronic digital display apparatus (or vernier) detection
Shifting value shows gap numerical value.This utility model avoids the impact on measurement result of the gap oral area shape, improves measurement essence
Degree, it is adaptable to band chamfering in engineering reality, fall garden, do not advise the accurate measurement in the gap of side port portion shape.
Above in conjunction with accompanying drawing, this utility model is exemplarily described, it is clear that this utility model implements and is not subject to
The restriction of aforesaid way, as long as have employed changing of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out
Enter, or the most improved design of the present utility model and technical scheme are directly applied to other occasion, all at this utility model
Protection domain within.
