Abstract

A positioning device for a standard inner ring of a locomotive bearing radial play measuring instrument is used for positioning of a bearing radial play measurement. The positioning device is characterized in that: a cylinder is connected with a flange seat, the flange seat is provided with a panel thereon, an inner bore of the panel has a tapered structure, a tower seat is arranged in a cavity of the flange seat, a standard bearing inner ring is sleeved outside the tower seat, an upper end face of the standard bearing inner ring is provided with a pressing plate, a cylinder lengthening screw presses the standard bearing inner ring outside the tower seat through the pressing plate and an adjusting plate in the tower seat, the tower seat has a step-type tower-shaped structure on which the standard bearing inner rings with different bearing types and different internal diameters can be installed, and the step has a tapered structure. The positioning device of the utility model effectively avoids the deficiency that the personnel moves outer components of the bearing up and down to measure the play, and effectively avoids the defect that the personnel is injured due to accidentally dropping the outer components in the carrying process, thus the positioning device has a high measurement safety performance; at the same time, by adopting taper fit, the positioning is performed quickly, accurately, stably and reliably, thereby ensuring accuracy and quality of the bearing radial play measurement, reducing labor intensity of operators, raising a measuring efficiency, and widening a measuring range of the measuring instrument.

Description

Locomotive bearing end-play measuring instrument standard inner ring locating device

Technical field

The utility model relates to the detecting instrument technical field, is a kind of locating device of large size bearing end-play measuring instrument standard inner ring specifically.

Background technology

As shown in Figure 2, the installing and locating mode of locomotive bearing end-play measuring instrument (like X294T bearing end-play measuring instrument) commonly used is following: be surface plate 11 on the measuring instrument, bearing standard inner ring 10 is fixed on the surface plate 11.In measuring process, operating personnel need the outer assembly of bearing is removed, and the height that surpasses bearing standard inner ring 10 just can be put outer assembly well, and measurement need be taken out outer assembly again after accomplishing.Labour intensity is big, and efficient is low, and also existing accidentally drops in the handling process is pounded injured danger.

Summary of the invention

For overcoming the deficiency of operation installing and locating in the prior art; The goal of the invention of the utility model is to provide a kind of locomotive bearing end-play measuring instrument standard inner ring locating device; Through changing the mode of bearing standard inner ring location; Thereby raise labour efficiency, quick, accurate alignment bearing standard inner ring carries out bearing end-play and measures.

For realizing above-mentioned purpose; The utility model technical scheme is: can realize that the cylinder that the standard rolling bearing inner ring moves up and down is connected with flange seat, panel is housed on the flange seat, the endoporus of panel is a pyramidal structure; The tower seat is contained in the cavity of flange seat; The standard rolling bearing inner ring is sleeved on outside the tower seat, and there is pressing plate the upper surface of standard rolling bearing inner ring, cylinder add long bolt in the tower seat pressing plate and can adjust disalignment and hold the adjustment plate of model standard rolling bearing inner race width difference the standard rolling bearing inner ring is fitted in outside the tower seat; The tower seat is for installing the notch cuttype tower structure of different bearing designation different inner diameters mark standard rolling bearing inner rings, and its ladder is a pyramidal structure.

Flange seat of the utility model and panel form a cavity; Sink in the cavity under the bearing standard inner ring; Drive the bearing standard inner ring through cylinder and move up and down, utilize the taper fit location of panel and tower seat simultaneously, the stepped design of adjustment plate and tower seat can satisfy different bearing designation standard rolling bearing inner rings and install; Widened the measurement range of detector, to realize the convenient and swift purpose that bearing end-play is measured of carrying out.

The utility model has compared with prior art effectively been avoided moving the outer assembly of bearing up and down through personnel and has been carried out the deficiency that play is measured, and accidentally drops in the handling process and pounded injured defective, and it is high to detect security performance; Simultaneously, adopt taper fit, fast and accurate for positioning, secure has guaranteed accuracy and detection quality that bearing end-play detects, has reduced operating personnel's operation intensity, has improved detection efficiency.

Embodiment

As shown in Figure 1; Cylinder 1 is connected with flange seat 2, and cylinder 1 can be realized moving up and down of standard rolling bearing inner ring 8, and panel 4 is housed on the flange seat 2; The endoporus of panel 4 is a pyramidal structure; Tower seat 3 is contained in the cavity of flange seat 2, and standard rolling bearing inner ring 8 is sleeved on outside the tower seat 3, and there is pressing plate 5 upper surface of standard rolling bearing inner ring 8; Cylinder adds pressing plate 5, the adjustment plate 9 of long bolt 7 in tower seat 3 standard rolling bearing inner ring 8 is fitted in outside the tower seat 3 through nut 6; Adjustment plate 9 can be done corresponding adjustment according to the height of different bearing designation bearing standard inner rings 8, and tower seat 3 is for installing the notch cuttype tower structure of different bearing designation different inner diameters mark standard rolling bearing inner rings 8, and its ladder is a pyramidal structure; The tapering of the hole taper of panel 4 and tower seat 3 each ladder is 1:10, conveniently to make bearing standard inner ring 8 be positioned at suitable height and different bearing designation different inner diameters mark standard rolling bearing inner rings 8 are sleeved on outside the tower seat 3, realizes accurately location.

The installation of the utility model: the former panel of locomotive bearing end-play detector (the X294T bearing end-play measuring instrument with commonly used is an example) is pulled down; The panel 4 that taper hole is arranged in the middle of being replaced by; Cylinder 1 is installed on flange seat 2; Connect cylinder in the inner space of flange seat 2 successively and add long bolt 7, adjustment plate 9, tower seat 3, the standard rolling bearing inner ring 8 that will use, pressing plate 5, clamp nut 6, again flange seat 2 is mounted to the below of panel 4 after connecting.

The use of the utility model: cylinder 1 is acted on the down stroke; Bearing standard inner ring 8 moves to below the panel 4, then the outer assembly of the bearing for preparing is pushed into the measuring position, cylinder 1 is acted on the up stroke again; The conical surface of the conical surface of tower seat 3 and panel 4 is accurate fits; Bearing standard inner ring 8 protrudes panels 4, is positioned at the endoporus of the outer assembly of bearing, begins to carry out the measurement of bearing end-play; After measure accomplishing, cylinder 1 is acted on the down stroke, tower seat 3 separates with panel 4, after driving bearing standard inner ring 8 and getting back to panel 4 following, will survey the outer assembly release of measured bearing measuring position.
