Description
Technical field
The utility model relates to electric fittings technical field, the fixation device of specifically a kind of Hall magnetic-sensing code.
Background technique
Encoder is to work out signal or data, be converted to the signal form that can be used to communication, transimission and storage
Equipment.The form of encoder is various, for Hall magnetic-sensing code comprising circuit board and magnetic grid two parts, need by
It is mounted on realization on motor tailing axle and tests the speed to motor.But currently without dedicated fixing device for installing, cause Hall magnetic
The installation accuracy of quick encoder is not high, to influence the accuracy to test the speed.
Utility model content
The purpose of this utility model is to provide a kind of fixation device of Hall magnetic-sensing code, which being capable of essence
Hall magnetic-sensing code really is installed on to the tailing axle of motor, it is convenient and efficient, improve the accuracy to test the speed.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of fixation device of Hall magnetic-sensing code, including extending shaft and installation cushion block, installation cushion block center are equipped with dress
Distribution, pilot hole aperture, which is greater than, extends shaft diameter；The tailing axle axis connection of the extending shaft and motor, installs cushion block and extending shaft is same
The heart, which assembles and passes through fixing bolt, is fixed on motor tail portion；The assembly bore edges for installing cushion block are equipped with annular card convex, install cushion block
It is additionally provided with mounting hole；The centre bore and annular snap of Hall magnetic-sensing code circuit board convex into clamping engagement, Hall magnetosensitive coding
The fixation hole of device circuit board and the mounting hole corresponding matching of installation cushion block；The magnetic grid of Hall magnetic-sensing code can be sheathed on extension
Axis periphery, and formed and cooperated with the circuit board of Hall magnetic-sensing code.
The utility model has the beneficial effects that being extended through tailing axle of the extending shaft to motor, the peace of extended coding device
Fill space；Installation medium of the cushion block as Hall magnetic-sensing code circuit board is installed, encodes Hall magnetosensitive by annular card convex
Device circuit board is accurately positioned, and makes magnetic grid that can keep best with the magnetic head on Hall magnetic-sensing code circuit board after mounting
Spacing obtains the optimal effect that tests the speed；The utility model structure is simple, easy to use.
