The measurement instrument is characterized by comprising an elastic iron block with a cavity structure, an electromagnetic induction output mechanism is mounted inside one end of the elastic iron block, a measurement terminal is fixedly connected to one end face of the elastic iron block, and the measurement terminal is a cavity structure, ceramic balls are distributed on the circumference of the measurement side of the measurement terminal, and a guide seat is connected to the outer end face of the measurement terminal.
Description
Technical field
The utility model relates to bearing and detects mechanical apparatus field, is specially a kind of surveying instrument of inner bore of miniature bearing.
Background technology
The detection of existing inner bore of miniature bearing, it is generally measured by manual, and it is wasted time and energy, and the precision that detects is low, efficient is low.
Summary of the invention
At the problems referred to above, the utility model provides a kind of surveying instrument of inner bore of miniature bearing, precision height, efficient height that it is time saving and energy saving, as to detect.
A kind of surveying instrument of inner bore of miniature bearing, its technical scheme is such:
It is characterized in that: it comprises elasticity iron, described elasticity iron is hollow core structures, the electromagnetic induction output mechanism is equipped with in the inside of one end of described elasticity iron, the end face of described elasticity iron one end is fastenedly connected with the mensuration terminal, described mensuration terminal is a hollow core structures, the periphery of the measurement side of described mensuration terminal is evenly equipped with Ceramic Balls, and the outer face of described mensuration terminal is connected with guide holder.
It is further characterized in that: described electromagnetic induction output mechanism specifically comprises insulation loop bar, little cover, coil, the afterbody of described insulation loop bar is fixedly installed in the periphery of described elasticity iron, described little cover is fixedly installed in the opposite side periphery corresponding to the described elasticity iron of described insulation loop bar installation site, described mounting coil is inner in described little cover, and the formed cavity inside of described coil wraps up described insulation loop bar;
Described coil is connected with lead, and described lead connects data output end after passing the fitting recess, hollow core structures of described elasticity iron inside;
Described insulation loop bar afterbody is connected in the installation screw thread of described elasticity iron by nut thread;
The periphery of the other end of described elasticity iron has arc groove;
The middle part of the hollow core portion of described elasticity iron is equipped with spring, and described spring is mounted in the mounting groove of elasticity iron inside.
After adopting structure of the present utility model, the bearing that needs is detected endoporus is set in the periphery of the measurement side of measuring terminal along guide holder, make Ceramic Balls contact with the endoporus that needs to detect bearing, the endoporus that needs to detect bearing acts on Ceramic Balls, Ceramic Balls is passed to the mensuration terminal with power, because measuring terminal is hollow core structures, be passed to an end that is fastenedly connected elasticity iron so measure the radially deformation of terminal measurement side, again because elasticity iron is hollow core structures, the electromagnetic induction output mechanism is equipped with in the inside that its elastic deformation is passed to an end of elasticity iron, the electromagnetic induction output mechanism changes into data output with deformation quantity, collect data by computing machine, get rid of those off-limits inner rings automatically, collect and be organized in the inner ring in the scope, when utilizing this structure detection inner ring, time saving and energy saving, the precision height that detects, the efficient height.
Description of drawings
Fig. 1 is a front view structural representation of the present utility model.
Embodiment
See Fig. 1, it comprises elasticity iron 1, elasticity iron 1 is hollow core structures, electromagnetic induction output mechanism 2 is equipped with in the inside of one end of elasticity iron 1, the end face of elasticity iron 1 one ends is fastenedly connected with measures terminal 3, measuring terminal 3 is hollow core structures, and the periphery of measuring the measurement side of terminal 3 is evenly equipped with Ceramic Balls 4, and the outer face of measuring terminal 3 is connected with guide holder 5.
Electromagnetic induction output mechanism 2 specifically comprises insulation loop bar 6, little cover 7, coil 8, the afterbody of insulation loop bar 6 is fixedly installed in the periphery of elasticity iron 1, insulation loop bar 6 afterbodys are connected in by nut 9 screw threads for fastening in the installation screw thread 10 of elasticity iron 1, and the periphery that screw thread 10 is positioned at a side of elasticity iron 1 is installed; Little cover 7 is fixedly installed in the opposite side periphery corresponding to the elasticity iron 1 of insulation loop bar 6 installation sites, and coil 8 is set in little cover 7 inside, coil 8 formed cavity inside wrap insulate loop bars 6;
Coil 8 is connected with lead 11, and lead 11 connects data output end 13 after passing the fitting recess 12, hollow core structures of elasticity iron 1 inside;
The periphery of the other end of elasticity iron 1 has arc groove 14;
The middle part of the hollow core portion of elasticity iron 1 is equipped with spring 15, and spring is mounted in the mounting groove of elasticity iron inside.
Its principle of work is as follows: the bearing that will need to detect endoporus is set in the periphery of the measurement side of measuring terminal 3 along guide holder 5, make Ceramic Balls 4 contact with the endoporus that needs to detect bearing, the endoporus that needs to detect bearing acts on Ceramic Balls 4, Ceramic Balls 4 is passed to power and measures terminal 3, measure the radially generation deflection of terminal 3, deflection is passed to elasticity iron 1, the insulation loop bar 6 of elasticity iron inside produces cutting magnetic line movement with coil 8, cause coil 8 to produce induction current, and be passed to data output end 13 by lead 11, screen according to output data then.The spring 15 of the hollow core portion of elasticity iron 1 plays the effect that adds severe deformation, play the function of having amplified output signal, the periphery of the other end of elasticity iron 1 has arc groove 14, has alleviated the weight of elasticity iron 1, make that the deflection of elasticity iron 1 is bigger, play the function of having amplified output signal.
