Radial run-out verification device for bearing body

Abstract

The invention discloses a radial run-out verification device for a bearing body. The radial run-out verification device for the bearing body has the characteristics that the radial run-out verification device for the bearing body is provided with a base, a verification platform, a dial indicator bracket, a dial indicator and rolling positioning devices, wherein the verification platform is aslant arranged on the base; the side surface of the verification platform is provided with the dial indicator bracket; the verification platform is provided with I-shaped grooves; the upper end of the dial indicator bracket is provided with the dial indicator; each I-shaped groove consists of an upper groove and a lower groove, wherein the upper groove and the lower groove of each I-shaped groove are arranged in parallel; the centers of the upper groove and the lower groove of each I-shaped groove are communicated via connecting holes; the I-shaped groove is provided with the two rolling positioning devices; each rolling positioning device comprises deep groove ball bearings, a set screw, gaskets and a nut, wherein each set screw is arranged in the upper groove and passes through the connecting holes via the gaskets to be fixedly connected with the nuts in the lower groove; the deep groove ball bearings are fixedly arranged on the end surfaces of the set screws to cause a bearing to be detected to carry out supporting and positioning rolling on the two rolling positioning devices without clamping and centering. The radial run-out verification device for the bearing body has the advantages of high measurement precision, high measurement speed and high efficiency.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a radial runout testing device for a bearing body. Background technique [0002] As we all know, the runout of the notch and end face of the bearing body is an important parameter index to determine the machining accuracy of the bearing body, and the machining accuracy of the bearing body directly affects the assembly of the bearing body. The amount of runout between the notch of the bearing body and the end surface not only determines the left and right alignment of the shaft, but also affects the adjustment of the shaft lift. The amount of runout between the spigot and the end face of the bearing body directly affects the clearance fit of the components in the bearing body. If the control is not good, it will affect the vibration and temperature rise of the bearing body. At present, the general trend of the development of the pump industry is to produce high-end pump...

Problems solved by technology

At present, the general trend of the development of the pump industry is to produce high-end pumps. The shape and position tolerance inspection of the bearing body is an important part of the pump assembly process control. At present, many bearing body runout inspection methods are directly clamped and aligned on the machine tool. Then check with a meter, this method is inefficient, time-consuming and laborious, and there are large operational errors
