Abstract
The invention relates to a test board capable of simultaneously measuring multiple rotational speed sensors. The test board comprises a support, a gear, a strip-shaped circular arc outer cover, a plurality of cylindrical sensor mounting seats and a control box; the gear is fixed onto the support and is driven by a motor, the strip-shaped circular arc outer cover is arranged on the outside of the gear, the cylindrical sensor mounting seats are fixed onto the outer cover and are used for mounting the rotational speed sensors, and the control box is used for controlling the motor when the motor rotates; openings on inner sides of the mounting seats are aligned with teeth on the gear along the radial direction of the gear; and transparent check blocks are arranged at the openings on the inner sides of the mounting seats. The test board has the advantage that technical problems of test differentiation and long test cycle due to the fact that an existing rotational speed sensor testing system only can test one sensor at a time are solved.
Description
Technical field
The present invention relates to a kind of speed probe test board.
Background technology
Existing speed probe test macro can only be tested a sensor at every turn, and after rewiring after emat sensor more, test condition may change thereupon.So can't know the difference with a collection of sensor.In addition, rewiring and take out stitches and also affected test period.
Summary of the invention
The purpose of this invention is to provide a kind of test board that can measure simultaneously a plurality of speed probes, its solved existing speed probe test macro can only test testing differentia that a sensor causes and test period long technical matters.
Technical solution of the present invention: a kind of test board that can measure simultaneously a plurality of speed probes is characterized in that: comprise support, be fixed on support by motor-driven gear, be arranged on the outer strip circular arc outer cover of gear, be fixed on a plurality of cylindrical-tube transducer mount pads that are used for installing speed probe on outer cover, the control box that is used for controlling electric machine rotation; The interior side opening of described mount pad is all radially aimed at tooth on gear along gear; The inboard opening part of described mount pad is provided with transparent catch.
Above-mentioned transparent catch is glass sheet or plastic sheet.
Advantage of the present invention:
1, the present invention can test a plurality of speed probes simultaneously, and testing efficiency significantly improves.
2, the tested object of all sensor of the present invention is the number of teeth of the gear that same average rate rotates, and has the effect of test result favourable identity.
Description of drawings
Fig. 1 is structural representation of the present invention;
Wherein: 1-support, 2-control box, 3-motor, 4-gear ,-5-mount pad, 6-speed probe, 7-sensor extension line, the transparent catch of 8-, 9-outer cover.
Embodiment
The present invention can measure the test board of a plurality of speed probes simultaneously, comprises support, is fixed on support by motor-driven gear, is arranged on the outer strip circular arc outer cover of gear, is fixed on 7 cylindrical-tube transducer mount pads that are used for installing speed probe on outer cover, the control box that is used for controlling electric machine rotation; The interior side opening of mount pad is all radially aimed at tooth on gear along gear; The inboard opening part of mount pad is provided with transparent catch; Transparent catch can be selected glass sheet or plastic sheet.In order to test large-scale rotating speed, control box should comprise that generally the motor frequency conversion control circuit changes motor speed to the number of teeth of gear between 180 to 200.
The principle of the invention: the present invention the outer circumferential sides of gear arrange one with the concentrically ringed outer cover of gear, fix a plurality of sensor installation seats on outer cover, at the interior side opening of mount pad, transparent catch is set, be used for preventing that sensor from inwardly dropping.When all placing a speed probe in each mount pad, a plurality of sensors just can carry out measurement of rotating speed to the number of teeth of a gear simultaneously.
Claims (2)
1. the test board that can measure simultaneously a plurality of speed probes is characterized in that: comprise support, be fixed on support by motor-driven gear, be arranged on the outer strip circular arc outer cover of gear, be fixed on a plurality of cylindrical-tube transducer mount pads that are used for installing speed probe on outer cover, the control box that is used for controlling electric machine rotation; The interior side opening of described mount pad is all radially aimed at tooth on gear along gear; The inboard opening part of described mount pad is provided with transparent catch.
2. the test board that can measure simultaneously a plurality of speed probes according to claim 1, it is characterized in that: described transparent catch is glass sheet or plastic sheet.
