Abstract

The invention provides spindle sleeve part inner/outer diameter detection equipment. The spindle sleeve part inner/outer diameter detection equipment comprises a work station, a pressure spring, a positioning sleeve, a sliding sleeve, a positioning mandrel, an inner diameter sensor probe, an outer diameter sensor probe and a handle, wherein the positioning sleeve and the positioning mandrel are mounted on the work station, the sliding sleeve is arranged between the positioning sleeve and the positioning mandrel, clearance fit is realized externally and internally, the positioning mandrel is arranged at a center of the sliding sleeve, a lower end of the sliding sleeve is provided with the pressure spring, the outer portion of the sliding sleeve is the positioning sleeve, the positioning sleeve is provided with a limit ring groove in a vertical direction, the limit ring groove is internally provided with the handle, the handle is connected with the sliding sleeve, and the inner sensor probe and the outer sensor probe are arranged on the positioning mandrel and the positioning sleeve. The detection equipment has properties of high display value precision and good detection data consistency, an inner diameter, an outer diameter, inner/outer circle roundness and conicity of workpieces can be detected through one-times operation, manpower cost is low, and the detection equipment is suitable for detecting dimensions, roundness and conicity of spindle sleeve circular ring products which are made through batch-scale production and have high inner-hole and outer-circle precision requirements.

Description

technical field [0001] The invention relates to testing equipment for hard alloy mechanical finishing products, in particular to testing equipment for inner and outer diameters of shaft sleeve parts. Background technique [0002] The precision assembly parts used for power transmission of centrifugal pumps, separators, and electric pumps in submersible electric pump units are wear-resistant parts of hard alloy shaft sleeves with a central axis as the center. The product has an inner hole and an outer circle. with steps. [0003] The existing equipment for testing the outer diameter, inner diameter, height and runout of this type of product is: the outer circle is tested with an outer diameter micrometer and a vernier caliper. When the tolerance of the outer circle is above 0.10, use a vernier caliper and an outer micrometer for detection; when the tolerance of the outer circle is 0.025 to 0.10, use an outer micrometer; when the tolerance of the outer circle is below 0.025, ...
