Abstract

The utility model relates to a measuring and testing technology, in particular to a measuring tool for shaft diameter which solves the problems of the measuring tool for shaft diameter with small range of radial and discloses a portable measuring instrument for shaft diameter, being characterized in that the utility model comprises a controlling box, two displacement sensor units, a wireless radio station, an antenna and a battery box, a shell at bottom of the controlling box which provides two displacement sensor units on two sides and the wireless radio station with the battery box beside and the antenna, and two locating blocks on two inclined planes of the shell which form a V-shaped body. The utility model has the advantages of being structured intensely and processed easily, being operated conveniently, being measured precisely and reliably because of the employment of the displacement sensor, and having a small measuring range and a high accuracy.

Description

The portable shaft cable diameter gauge
Technical field
The utility model relates to metrological testing technology, belongs to the diameter measurement device especially.
Background technology
The measurement of train wheel shaft diameter, most important to vehicle safe driving, the diameter of axle cooperated pine or tension all can cause overturn accident.Because the measurement range of train wheel shaft diameter is little, precision is high, and existing traditional measurement all is to use the external diameter kind of calliper, the measurement range is big, precision is low.
Summary of the invention
For solving the diameter measurement measurer of radially little range, the utility model provides a kind of portable shaft cable diameter gauge, and it can improve measuring accuracy effectively, improves and measures benefit.
The utility model is to realize by following technical scheme, it is made up of control enclosure, displacement sensor component, wireless station, antenna, battery case, its structural feature is that the control enclosure below is provided with housing, the inside surface of housing is semicircle, outside surface is half octagon, on the two sides of housing, respectively be provided with two displacement sensor components, the transducer probe assembly of this assembly is located in the through hole of housing two sides, the place ahead at housing is provided with wireless station, the wireless station top is provided with antenna, and wireless station is provided with battery case on one side.
Respectively be provided with two holes on two inclined-planes of above-mentioned housing, be provided with locating piece in the hole, this two sides locating piece forms a V-arrangement body on the semicircle in housing.
Above-mentioned displacement sensor component is made up of sensor drive box, sensor, accent piece installing, sensor comprises sensor body, transducer probe assembly, transfer piece installing to constitute by guide pin bushing, fastening screw nut, guide pin bushing nut, the threaded one end of sensor body links to each other with two fastening screw nuts, one end of guide pin bushing is connected with housing by screw, and the guide pin bushing other end is connected with the guide pin bushing nut by screw thread.
Above-mentionedly on two inclined-planes of housing, respectively be provided with a handle.
The utility model compact conformation is processed simply, and is easy to operate, owing to adopt displacement sensor, measures accurately and reliably, and the measurement range is little, precision is high.
Description of drawings
The utility model is described in further detail below with reference to the embodiment of accompanying drawing.
Fig. 1 is the utility model external form vertical view.
Fig. 2 is a structural profile synoptic diagram of the present utility model.
Embodiment
Among Fig. 1, control enclosure 3 is equipped with in the top of housing 5.The two sides of housing 5 respectively are equipped with and 7, two sensors of sensor drive box are housed between 6, two displacement transducers of two displacement transducers are linked to each other with the sensor drive box, and present embodiment adopts Beijing DA-1 of Beijing Inst. of Water Conservancy and Water and Power Science type sensor.In the place ahead of housing 5 wireless station 2 is housed, present embodiment adopts Shenzhen fast FC201/E of communication apparatus company limited type wireless station that reaches of friend, antenna 1 is equipped with in the top in wireless station, and the battery case 4 of rechargeable lithium ion batteries is equipped with on one side in wireless station, does the power supply of measuring instrument and uses.Handle 8 is used for portable.When measuring, earlier the axle of measured axis number is input in the control enclosure by the keyboard on the control enclosure 3.Again the diameter of axle of measured axis is measured.Sensor 6 is delivered to control enclosure to the diameter of axle signals that record by sensor drive box 7, and control enclosure shows axle number and measurement data.And the axle of input number and the diameter of axle digital signal surveyed handled, signal sends by the antenna in the wireless station 21 more then, can be for the data server that is located at far-end.And at the data server of far-end, receive by the antenna in the wireless station that is located at its next door, be sent to data server receiving signal, by data server data-in storehouse.
Among Fig. 2, two fastening screw nuts 9 are housed on the threaded one end of sensor body 10, regulate the axial location of transducer probe assembly 11 by fastening screw nut.Must be adjusted to the diameter of axle nominal size of measured axis before measurement earlier, because this diameter measurement instrument is to be only limited to the special measuring tool of measuring a kind of specification diameter of axle, the radial measurement range of its measured axis is very little, and present embodiment is a train wheel shaft diameter measurement.Sensor guide pin bushing 12 is housed on the sensor body cylindrical, and an end of guide pin bushing is fixed by screw and housing, and the other end of guide pin bushing is equipped with guide pin bushing nut 13 outward.When regulating the axial location of transducer probe assembly 11, earlier guide pin bushing nut 13 is backed out, regulated fastening screw nut then.Two locating pieces 14 respectively are housed on two inclined-planes of housing, and the two sides locating piece constitutes a V-arrangement body on the semicircle in housing, to be used for the measured axis measurement and positioning.
