Summary of the invention
The technical matters that the present invention will solve provides a kind of shaft extension pick-up unit, can measure the axial dimension of Motor Shaft end face to groove floor easily and accurately.
For solving the problems of the technologies described above; Technical scheme provided by the invention is a kind of shaft extension pick-up unit; Comprise body and be connected the dial gauge on the body; Be provided with the axially extending bore that cooperates with Motor Shaft in the said body, the lower surface of body is against on the groove floor of electric motor end cap, and the thimble of dial gauge is against on the end face of Motor Shaft.Adopt this programme, effectively improved and measured the convenience of Motor Shaft end face to the axial dimension of groove floor, the step that operates is easy, saves man-hour, has improved work efficiency, has reduced production cost.
As a kind of improvement, said body is provided with the securing member that body is fixedly connected with Motor Shaft.Relative stability being provided with on the body after securing member has guaranteed to connect between Motor Shaft and the body is convenient for measuring.
As a kind of improvement, said securing member is a bolt, and body is provided with the radial screw bore that cooperates with bolt, and bolt passes radial screw bore and is against on the Motor Shaft.If bolt is the connection securing member between body and the shaft, bolt is selected for use conveniently, and is threaded stability better.
As a kind of improvement, be provided with web member between said body and the dial gauge, the lower end of web member is connected with body-fixed, and the upper end of web member is fixedly connected with dial gauge.Between body and dial gauge, establish web member, improved the convenience of installing between body and the dial gauge.
As a kind of improvement; Said web member is the L shaped plate part; Said L shaped plate part comprises orthogonal side plate I and side plate II; Said dial gauge is provided with and supplies the thimble thimble sleeve pipe of slippage up and down, and the thimble sleeve pipe is fixed on the side plate I and the parallel axes of the axis of thimble sleeve pipe and body, and the side plate II is connected with body-fixed.If the L shaped plate part is done web member, profile is comparatively attractive in appearance, and orthogonal side plate I and side plate II couple together body and dial gauge, can guarantee the position relation that the axis of axis and the body of thimble parallels simultaneously.
As a kind of improvement, the lower end of said body is provided with boss, and the end face of said boss is against on the bottom surface of groove of end cap.The body lower end is provided with the groove fit on boss and the end cap, guarantees the compactedness that cooperates between end cap groove and the body easily.
The invention provides a kind of shaft extension pick-up unit, its beneficial effect is: effectively improved and measured the convenience of Motor Shaft end face to the axial dimension of groove floor, the step that operates is easy, saves man-hour, has improved work efficiency, has reduced production cost.
