Description
Technical field
The utility model relates to a kind of junction box levelling device.
Background technology
Shaft coupling, as a kind of coupling of shaft system part, is widely used in mechanical drive industry.When shaft coupling is installed, center centering to be carried out to two half a couplers, make diaxon axle system deviation reach minimum.At present, existing junction box levelling device mainly contains two kinds of forms: one relies on magnetic force to be adsorbed on half a coupler by alignment device to detect, and its shortcoming is: during measurement, need to rotate shaft coupling, magnetic-adsorption is more weak, causes dial framework often movement, affects measurement accuracy.Another kind of survey instrument is made up of surveying instrument, instrument hoop, measurement bay and holding frame usually, and the shortcoming of this survey instrument is: each measurement all will make special instrument hoop according to the external diameter of shaft coupling, and specification is not general, inconvenient operation.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to propose a kind of junction box levelling device, can measure the shaft coupling of various outer diameter, for the centering of shaft coupling, measure fast and accurately property high, have use and easy accessibility, highly versatile feature.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of junction box levelling device, comprise main shaft three-jaw holding frame 3, main shaft three-jaw holding frame 3 comprises spindle rod 9, the axle head cover of spindle rod 9 has the setting nut 2 of band pad, setting nut 2 is fixed on spindle rod 9 by screw thread, on spindle rod 9, cover has set collar 12 and slip ring 13, set collar 12 is fixedly connected with spindle rod 9, slip ring 13 and spindle rod 9 are slidably connected, set collar 12 clamps movable claw 10 by moving rotary is secondary be connected with three, three clamping movable claws 10 are connected with three movable push bars 11 respectively by moving rotary pair, movable push bar 11 is connected with slip ring 13 by moving rotary pair, the spindle rod 9 of main shaft three-jaw holding frame 3 is connected by screw thread is vertical with axial holding frame 5, on axial holding frame 5, axially measurement dial gauge 4 held by geometrical clamp, axial holding frame 5 is connected by screw thread is vertical with radial holding frame 7, on radial holding frame 7, radial measurement dial gauge 6 held by geometrical clamp.
The front end of described three clamping movable claws 10 is narrow support bar 14 with the position contacted with reference to shaft coupling 1 inside surface.
Described three clamping movable claws 10 are separated by respectively 120 ° and are arranged around spindle rod 9, and three clamping movable claws 10 are large with footpath etc.
Described three movable push bars 11 are measure-alike.
Because existing junction box levelling device is justified as examination criteria mainly with the outside surface of shaft coupling, and the cause of shaft coupling owing to coordinating with axle, the machining precision of its inside surface circle is often higher than outside surface circle, therefore, the utility model with shaft coupling inside surface for measure reference standard, can find the central axis with reference to shaft coupling more accurately, thus improve the concentric centering precision of shaft coupling, measurement accuracy is high, adjustability is strong; The component structural that the utility model adopts is simple, easily manufactured, processing cost is low, operation and easy accessibility; By calculating, regulating movable push bar and the length dimension clamping movable claw, the measurement of the central axis of large footpath shaft coupling can being realized, lengthening the length of spindle rod by regulating, can the centering work of remote shaft coupling in fact, the shaft coupling of various outer diameter can be measured, highly versatile.
