Large workpiece detection platform with inner hole

Abstract

The invention relates to a large workpiece detection platform with an inner hole, and effectively solves the problems that measurement and adjustment are disjointed during detection of a large-sized workpiece, and time and labor are wasted. According to the technical scheme, the device comprises a horizontal base, a plurality of vertical blind holes are uniformly distributed in the circumference of the upper surface of the base; an oil supply pipe communicated with the bottoms of the blind holes is arranged below the base, a plug block attached to the inner wall of each blind hole is installedin each blind hole, a ball capable of rolling freely is embedded in the upper end of each plug block, a horizontal annular carrying plate is arranged above the base, and the multiple plug blocks moveupwards so that the multiple ball carrying plates can be supported. A vertical rotating shaft is installed in the center of the base, the upper end of the rotating shaft penetrates through an annularhole of the carrying plate, a horizontal rhombus structure is installed on the rotating shaft, and the rhombus structure can stretch out and draw back to adjust the length in the left-right direction. According to the invention, measurement and adjustment are combined, the measurement reference and the installation reference are unified, the reliability of the detection result is higher, and theworkpiece can be flexibly adjusted and stably locked.

Description

technical field [0001] The invention relates to the field of workpiece detection, in particular to a large workpiece detection platform with inner holes. Background technique [0002] Large parts with inner holes are widely used in large equipment, such as large gears, large shaft sleeves, large washers, etc. Before installation and use, the parts need to be tested on the testing platform. The testing requires the parts to be aligned with the testing platform. At present The benchmark generally used in centering is the theoretical center of the inner hole of the workpiece, and repeated measurements and adjustments are made until the concentricity meets the detection requirements. This method of measurement and adjustment is carried out independently, and is out of touch with each other. The human error is relatively large, and it needs to be repeated. Measurement and adjustment, the time to adjust the workpiece is much longer than the detection time; in addition, the current...
