Heart point clamps calibration bolt and reads data, then carry out tension test to calibration bolt and pass through vernier caliper or thousand points again to it
Ruler carries out linear measure longimetry to calibration bolt, last reads data and obtains the difference of test front and back.It is measured in this way to inspection
The skill requirement of survey personnel is very high, and in measurement, the slight oscillatory of the slight oscillatory of calibration bolt and vernier caliper or micrometer is all
The accuracy of reading data can be seriously affected, unfamiliar testing staff is difficult to measure accurate data, and measure
Overlong time efficiency is extremely low.So that there is time of measuring is long for the calibration bolt length after measurement tension test at present, wave is detected
Dynamic big, operating difficulties, reading is inconvenient, and the error of measurement is big, and the probability of outcome of measuring error is high, the low problem of measurement efficiency.
The disclosure of background above technology contents is only used for the design and technical solution that auxiliary understands the utility model, not
The prior art for necessarily belonging to present patent application shows above content in the applying date of present patent application in no tangible proof
In the case where having disclosed, above-mentioned background technique should not be taken to the novelty and creativeness of evaluation the application.
Utility model content
There is detection operating difficulties for existing measurement calibration bolt test anterior-posterior length in the utility model, error is big and wrong
The accidentally high problem of rate provides a kind of calibration bolt length and simply detects assembly.The assembly is equipped with pedestal, guide rod, gauge stand, magnet,
Calibration bolt can be quickly located on pedestal by magnet, guide rod both ends connect pedestal and gauge stand, and gauge stand both ends have equipped with table
Installation position is for installing dial gauge or amesdial, and easy to operate using the assembly, time of measuring is fast, and data are accurate, detection efficiency
It is high.
In order to achieve the goal above, this technical solution adopted is as follows:
A kind of calibration bolt length simply detects assembly, including pedestal, magnet, guide rod, gauge stand；The middle of the base is equipped with
One guide rod installing hole；The tail end of the guide rod is equipped with screw thread, and the top of screw thread is equipped with limited block, for limiting guide rod and pedestal
Excessive connection, the guide rod is vertical with pedestal to be connect；The distribution of magnets is in guide rod installing hole both sides, for adsorbing calibration spiral shell
Bolt quickly positions；The gauge stand both ends are equipped with table and have mounting hole, for installing dial gauge or amesdial, are equipped with guide rod in the middle part of gauge stand
Connecting hole, for connecting with guide rod, the gauge stand is connect with guide rod and gauge stand can be up and down in guide rod.
Further, the pedestal is round or rectangular；The base bottom is set there are four fixing support, is used to support total
At firm placement.
Further, the magnet and pedestal in the same plane, are stably placed at calibration bolt to be measured on pedestal.
Further, the guide rod is that the mode that threaded screw bore tightens or nut is fixed is connect with pedestal.
Further, the table tool mounting hole of the gauge stand and the side of guide rod connecting hole are equipped with locking screw keyhole, use spiral shell
Bolt cooperation is for locking table tool and gauge stand.
Further, it is respectively equipped with an opening copper sheathing in the table tool mounting hole, prevents locking screw in locking table tool
Bolt accidentally injures table tool.
Compared with prior art, it the advantages of the utility model and has the beneficial effect that
1, it by the way that two magnet are arranged in pedestal both sides, can quickly positioning and demarcating bolt, realization fast accurate measure.
2, table being equipped at gauge stand both ends and having installation position, mountable dial gauge or amesdial are carried out to calibration bolt measurement, behaviour
Make simply, reading is fast.
3, it is equipped with opening copper sheathing in table tool mounting hole, can prevents clamping screw accidental injury table from having.
4, this assembly can measure bolt of different specifications and sizes.
5, this assembly framework is simple, at low cost, easily operated, and measurement accuracy is high, and detection efficiency is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail With reference to embodiment.It is stated under it is emphasized that
It is bright to be only exemplary, rather than in order to limit the scope of the utility model and its application.
As shown in Figure 1, a kind of calibration bolt length simply detects assembly, including pedestal 1, magnet 2, guide rod 3, gauge stand
4；The pedestal 1 be it is round or rectangular, the middle of the base is equipped with a guide rod installing hole 5, and base bottom sets that there are four fixed
Pedestal 8 is used to support the firm placement of assembly；The tail end of the guide rod is equipped with screw thread 6, and the top of screw thread is equipped with limited block 7, is used for
The excessive connection of guide rod 3 and pedestal 1 is limited, the guide rod 3 is vertical with pedestal 1 to be connect, and guide rod 3 and pedestal 1 are threaded screw bore torsion
