Acceptance inspection tool for mounting dimension of small-amount standalone product

Abstract

The invention discloses an acceptance inspection tool for mounting dimension of a small-amount standalone product. The tool comprises a bottom plate, and measuring cylinders which are arranged on the bottom plate; each measuring cylinder comprises a cylinder section and a thread section; a plurality of threaded holes, which are screwed through the thread sections of the measuring cylinders, are arranged in the upper surface of the bottom plate; the arrangement mode of the threaded holes and the space between the threaded holes are consistent with those of mounting holes of the inspected standalone product; the measuring cylinders are in clearance fit with the mounting holes of the inspected standalone product. According to the acceptance inspection tool for the mounting dimension of the small-amount standalone product, the mounting dimension of the inspected standalone product can be judged to be qualified under the conditions that corresponding measuring cylinders can smoothly pass through all mounting holes of the inspected standalone product can smoothly and the mounting surface of the inspected standalone product is closely clung to the bottom plate of the tool.

Description

technical field [0001] The invention belongs to the technical field of mechanical measurement, and in particular relates to a tool suitable for checking and accepting the installation size of small-batch stand-alone products of spacecraft. Background technique [0002] With the mass development of spacecraft, the workload of checking and accepting the installation dimensions of small-batch stand-alone products is gradually increasing. Whether the installation dimensions are qualified or not directly affects the work quality and progress of spacecraft. [0003] In the past, the acceptance tool for checking and accepting the installation size of small-batch stand-alone products was a vernier caliper. Acceptance personnel use vernier calipers to measure at least eight times to complete the acceptance of the installation size of a stand-alone product. When accepting small batches of stand-alone products, the acceptance personnel need to repeatedly measure the same installation s...

AI Technical Summary

Problems solved by technology

[0005] 1. Use vernier calipers to measure at least eight times to complete the installation size acceptance of a stand-alone product, and the number of small-batch stand-alone products is large, and the acceptance efficiency is low;

[0006] 2. The installation holes are arranged in a non-rectangular shape, and the data of the installation size needs to be obtained through mathematical calculations, and the cumulative error is relatively large
