Part fixed plate, encoder fixed plate surround box frame shape, there is upper and lower runner in box frame, and upper and lower runner has middle shaft through-hole, have and turn
Axis passes through middle shaft through-hole, and upper runner is fixed in shaft, and lower runner is fixed on the rotary axle box of encoder, test specimen sensing
The output shaft of device is fixedly connected with upper runner, and the rotary axle box of encoder is fixedly connected with the shaft other end.
Upper runner is bolted in shaft, and upper runner is provided with loose slot along center, has movable holddown in loose slot,
There is baffle on loose slot, movable holddown is limited in loose slot by baffle, is had and is adjusted screw across upper runner and press against activity
On briquetting, adjusts screw and upper runner is fixedly connected with the output shaft of test specimen sensor by movable holddown, there is bolt to wear
It crosses down the rotary axle box of runner and encoder and they is fixedly connected with shaft.
The utility model has the beneficial effects that: the output shaft of tested sensor and the upper runner of device can be made closely to connect
Touching guarantees to keep same axle center when sensor rotation, improves the accuracy of test, while the structural member of the device is secured, install
It is convenient, it is easy to adjust.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model,
Fig. 2 is the top view of Fig. 1.
Specific embodiment
