Detailed Description
The utility model is described in detail with the following figures, as shown in the figures, the utility model comprises a frame, a motor 1 is arranged on the frame, the motor is connected with one end of a flexible coupling 3 through a speed reducer 2, the other end of the flexible coupling is connected with one end of a rotating shaft 4, the rotating shaft 4 is arranged on a vertical plate 5, a thread go-no-go gauge 6 is arranged on the other end of the rotating shaft, and a measured nut 7 is screwed on the thread go-no-go gauge; the gauge head of the dial gauge 8 abuts against the radial outer side of the measured nut.
The rotating shaft is fixed on the vertical plate 5 through a bearing. The vertical plate is vertically fixed on a bottom plate of the frame; the riser sets up the through-hole, sets up the bearing in the through-hole, and the pivot setting is on the hole of bearing.
The motor 1 is connected with a motor controller, and the motor controller is connected with a forward and reverse rotation switch 10 and a speed regulation switch 9; the positive and negative rotation switch and the speed regulation switch are both arranged on the frame.
The principle of the utility model is that: the measured nut and the thread go gauge are integrally or detachably installed by utilizing the positive and negative rotation of the motor; the screw thread go gauge is installed and is surveyed the nut and then rotate along with the pivot, detects by the amesdial radial runout of being surveyed the nut. In order to reduce the influence of the generated micro vibration on the precision of the rotating shaft when the motor and the speed reducer rotate, the speed reducer is connected with the rotating shaft through a flexible connection coupler. The flexible connection coupling can be a commercially available product, such as the product of the weghai sanfeng electronic technology limited.
