Abstract
The invention discloses an instrument for measuring the diameters of a journal and a wheel seat, in particular to a device for detecting the diameters of a journal of an axle and a wheel seat of a rail wagon, which comprises a measuring part, a data converting part and a digital display, wherein the measuring part consists of a V-shaped groove, a sensor installation seat and a sensor; the sensor installation seat is positioned on an angular bisector of the V-shaped groove; and the sensor is arranged on the sensor installation seat. With the structure, the positioning of workpieces can be realized by the sensor through the V-shaped groove; the sensor transmits the measured signal to the digital display through a data converter; and the measured signal is displayed by the digital display, so the problems that a micrometer cannot accurately position and artificial read has errors in the prior art are solved.
Description
Affiliated technical field:
The present invention relates to a kind of axle journal of lorry axle and device of wheel seat diameter measured.
Background technology:
At present, lorry axle surveying work of axle journal and wheel seat diameter in process all is to be carried out with milscale by the workman, has the inaccurate and artificial big problem of reading error in location in measuring process.
Summary of the invention:
In order to address the above problem, the high precision axle journal and the wheel seat diameter measuring device that the invention provides a kind of accurate location that can realize and the measurement result numeral is shown.
The technical solution adopted for the present invention to solve the technical problems is: instrument for measuring diameters of journal and wheel seat comprises measurement section, data converter and digital indicator three parts.Measurement section is made up of V-type groove, sensor mount pad and sensor, the sensor mount pad is on the angular bisector of V-type groove, sensor is installed on the sensor mount pad, during measurement, the V-type groove positions the position of the relative axle journal of sensor, wheel seat, utilizes the diameter of sensor measurement axle journal or wheel seat; Data converter is connected with sensor, and sensor signal is become the signal that mates with numeric display unit, and digital indicator is connected with DTU (Data Transfer unit), realizes that final data shows.
When measured workpiece was axle journal, the length of sensor mount pad and axle journal diameter were complementary.
When measured workpiece was wheel seat, the length of sensor mount pad and wheel seat diameter were complementary.
The invention has the beneficial effects as follows, improved the measuring accuracy of diameters of journal and wheel seat, realized that the digitizing display structure of measurement data is simple, easy to use.
Description of drawings:
Fig. 1 is a diameters of journal and wheel seat detector synoptic diagram;
Fig. 2 is the measurement section structural representation;
Fig. 3 is the measuring operation synoptic diagram.
1. measurement section among the figure, 2.V type groove, 3. sensor, 4. sensor mount pad, 5. data converter, 6. digital indicator, 7. connecting line, 8. measured workpiece.
Embodiment:
In Fig. 3, the V-type groove (2) of measurement section (1) is stuck on the measured workpiece (8), and sensor (3) will be aimed at the center of circle of measured workpiece (8) automatically, promptly measure the radius of measured workpiece (8), by data converter (5), in digital indicator (6), show measured workpiece (8) diameter at last.
