Abstract
A rotation angle measuring device belongs to angle measuring devices and comprises a mounting base, an angle sensor, a crank, a first pin shaft, a connecting rod, a second pin shaft, a support seat, a movable arm connecting rod, a mounting plate and a connecting shaft; the angle sensor is fixed on a frame through the mounting base; the angle sensor is connected to the support seat; the output shaft of the angle sensor is connected with the crank through the connecting shaft; the crank is connected with a measured piece through the connecting rod; the crank is hinged with the first pin shaft through the connecting rod; the connecting rod is hinged with the movable arm connecting rod through the second pin shaft; the movable arm connecting rod is hinged with the mounting plate; and the mounting plate is connected to a movable arm. The utility model has the advantages that the angle sensor in the angle measuring mechanism is mounted and fixed conveniently and set to zero flexibly; by virtue of a four-bar mechanism, the proportion of the output angle of the angle sensor in the angle measuring mechanism to the rotation angle of the measured piece is 1 to 1, so that signals can be processed conveniently after being collected.
Description
Technical field
The utility model relates to a kind of angle measurement unit, particularly a kind of rotating angle measurement apparatus.
Background technology
At present, general angle measurement unit all requires to be directly installed on the measured piece, directly drives the installation shaft rotation of angular transducer by the rotation of measured piece, the variation that can record angle, and this angle measurement unit is effectively practical under normal conditions.But this mounting means brings very big inconvenience under the part situation, and it is inconvenient that angular transducer installs and fixes zeroing.
The utility model content
The purpose of this utility model is to provide a kind of: install and fix flexible, zero-bit adjusting rotating angle measurement apparatus freely.
The purpose of this utility model is achieved in that this angle measurement unit comprises: mounting base, angular transducer, crank, first bearing pin, connecting rod, second bearing pin, supporting base, swing arm connecting rod, installing plate and coupling shaft, angular transducer is fixed on the frame by mounting base, angular transducer is connected on the supporting base, the angular transducer output shaft links to each other with crank by coupling shaft, crank is connected with measured piece by connecting rod, and crank and connecting rod are hinged by first bearing pin; Connecting rod and swing arm connecting rod are hinged by second bearing pin, and swing arm connecting rod and installing plate are hinged, and installing plate is connected on the swing arm.
Beneficial effect, owing to adopted such scheme, angular transducer is fixed on the frame by mounting base, the output shaft of angular transducer is connected with crank by the coupling shaft that is supported by supporting base, crank, connecting rod, swing arm connecting rod are hinged by first bearing pin, the swing arm connecting rod is fixed on the measured piece by installing plate, and angular transducer, crank, connecting rod, pivot arm, frame have just been formed a four-bar mechanism like this.In the measured piece motion process, the variation of its angle is converted to the rotation of angular transducer output shaft by this linkage assembly, exports corresponding electric signal by sensor.
By the mechanism of four connecting rods, make unnecessary being installed on the test specimen of angular transducer in this measurement of angle mechanism, this make the installing and fixing of angular transducer, returning to zero brings great convenience, and has very practical effect.Angular transducer goes out the variation of measured piece position with the angle variables signal conveys, and the output signal of measured piece and angular transducer is 1: 1 relation, and angular transducer is transformed into electric signal to angle signal and is transported in the various controllers.Install and fix flexible, zero-bit and regulate freely, reached the purpose of this utility model.
Advantage: angular transducer installs and fixes conveniently, returns to zero flexibly in the measurement of angle mechanism; Four-bar mechanism makes that the output angle of angular transducer becomes 1: 1 relation with the angle of measured piece rotation in the measurement of angle mechanism, and this can bring after acquired signal, to the convenience of signal Processing.
