Abstract

The utility model relates to an intermediate diameter runout detection device used for a precise screw rod. The front part of a detection table is a horizontal working face. The rear part of the detection table is provided with a detection table wall board. A guide rail extending in the length direction of the detection table is fixed on the front end face of the upper part of the detection table wall board. A slide base capable of moving along the guide rail is installed on the guide rail. A dial indicator is fixed on the slide base. Adjustable support bases are arranged on two ends of the horizontal working face of the detection table. The adjustable support bases are equipped with a V-shaped support base each. Two ends of the to-be-detected screw rod are supported by the V-shaped support bases and the axial line of the to-be-detected screw rod is made parallel to the axial line of the guide rail. A guide sleeve is also fixed on the slide base. A guide rod capable of sliding up and down along the guide sleeve is arranged in the guide sleeve. The upper end of the guide rod is planar and contacts with a detection contact of the dial indicator. The lower end of the guide rod is connected with a screw rod testing head fitting threads of the to-be-detected screw rod. A knurling hand wheel is installed on a shaft end on a side of the to-be-detected screw rod. The intermediate diameter runout detection device can be used for detecting the screw rod independently and production equipment such as a lathe and the like are not needed to use.
