Description
Technical field
The present invention relates to Bearing testing technical field of mechanical equipment, be specially the 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 detected is low, efficiency is low.
Summary of the invention
For the problems referred to above, the invention provides the surveying instrument of inner bore of miniature bearing, its precision that is time saving and energy saving, that detect is high, efficiency is high.
The 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, 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 mensuration terminal, described mensuration terminal is 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 of the described elasticity iron corresponding to described insulation loop bar installation site, described mounting coil is inner in described little cover, and the cavity inside that described coil is formed wraps up described insulation loop bar;
Described coil is connected with wire, and described wire is through connection data output terminal after the fitting recess of described elasticity iron inside, hollow core structures;
Described insulation loop bar afterbody is connected to by nut thread in the installation screw thread of described elasticity iron;
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 provided with spring, and described spring top is loaded in the mounting groove of elasticity iron inside.
After adopting structure of the present invention, the periphery of measurement side measuring terminal is set in along guide holder by needing the bearing detecting endoporus, make Ceramic Balls and need to detect the endoporus of bearing and contact, the endoporus detecting bearing is needed to act on Ceramic Balls, power is passed to mensuration terminal by Ceramic Balls, because mensuration terminal is hollow core structures, so the radial deformation measuring terminal measurement side is passed to the one end being fastenedly connected elasticity iron, again because elasticity iron is hollow core structures, electromagnetic induction output mechanism is equipped with in the inside that its elastic deformation is passed to one end of elasticity iron, deformation quantity is changed into data and exports by electromagnetic induction output mechanism, data are collected by computing machine, those off-limits inner rings of automatic eliminating, collect and be organized in the inner ring in scope, when utilizing this structure detection inner ring, time saving and energy saving, the precision detected is high, efficiency is high.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
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 end is fastenedly connected with and measures terminal 3, measuring terminal 3 is hollow core structures, and the periphery measuring the measurement side of terminal 3 is evenly equipped with Ceramic Balls 4, and the outer face 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 afterbody is connected in the installation screw thread 10 of elasticity iron 1 by nut 9 screw threads for fastening, installs the periphery that screw thread 10 is positioned at the side of elasticity iron 1; Little cover 7 is fixedly installed in the opposite side periphery of the elasticity iron 1 corresponding to insulation loop bar 6 installation site, and it is inner that coil 8 is set in little cover 7, the cavity inside wrap insulate loop bar 6 that coil 8 is formed;
Coil 8 is connected with wire 11, and wire 11 is through connection data output terminal 13 after the fitting recess 12 of elasticity iron 1 inside, hollow core structures;
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 provided with spring 15, and spring top is loaded in the mounting groove of elasticity iron inside.
Its principle of work is as follows: be set in needing the bearing detecting endoporus the periphery of measurement side measuring terminal 3 along guide holder 5, make Ceramic Balls 4 and need to detect the endoporus of bearing and contact, the endoporus detecting bearing is needed to act on Ceramic Balls 4, power is passed to and measures terminal 3 by Ceramic Balls 4, the radial direction measuring terminal 3 produces deflection, deflection is passed to elasticity iron 1, insulation loop bar 6 and the coil 8 of elasticity iron inside produce cutting magnetic line movement, coil 8 is caused to produce induction current, and be passed to data output end 13 by wire 11, then screen according to output data.The spring 15 of the hollow core portion of elasticity iron 1 plays the effect adding severe deformation, play the function being exaggerated output signal, the periphery of the other end of elasticity iron 1 has arc groove 14, alleviates the weight of elasticity iron 1, make the deflection of elasticity iron 1 larger, play the function being exaggerated output signal.
