A crawler chain first joint inspection tool and its inspection method

Abstract

A crawler chain first section inspection tool and its detection method are used to quickly and accurately detect the machining accuracy of the first chain section. The first section of the chain has two oppositely arranged chain pieces, and the chain pieces have large and small shaft holes and installation grooves. It includes a checker body, the checker body includes a detection head adapted to the installation groove and a detection rod adapted to the small shaft hole, the detection head is formed with a The first reference plane and the second reference plane are in contact with the side wall of the installation groove, and the detection rod is a cylinder vertically connected to the first reference plane of the detection head.

Description

technical field [0001] The invention relates to a detection tool for the first section of a crawler chain and a detection method thereof. Background technique [0002] refer to figure 1 and figure 2 As shown, the chain piece 1 requires the blank end faces A and B of the dust-proof hole, the large shaft hole 12 and the small shaft hole 11. 1. The process of the small shaft hole 11 did not control the shape tolerance well, resulting in out-of-tolerance parallelism and verticality. These problems can be overcome by assembling equipment in the factory, but as the first section of the crawler chain, that is, the chain is assembled into a closed ring. The chains have installation grooves for connection and need to be assembled on site. Without the support of assembly equipment in the factory, if the processing accuracy of the chains cannot meet the requirements, it will be difficult to assemble. At present, there is no It is a checking tool for testing the installation accurac...

AI Technical Summary

Problems solved by technology

[0002] refer to figure 1 and figure 2 As shown, the chain piece 1 requires the blank end faces A and B of the dust-proof hole, the large shaft hole 12, and the small shaft hole 11 to have a verticality of 0.15 and a parallelism of the rail surface C to be 0.2. 1. The process of the small shaft hole 11 did not control the shape tolerance well, resulting in out-of-tolerance parallelism and verticality. These problems can be overcome by assembling equipment in the factory, but as the first section of the crawler chain, that is, the chain is assembled into a closed ring. The chain pieces have installation grooves for connection, and they need to be assembled on site. Without the support of assembly equipment in the factory, if the machining accuracy of the chain pieces cannot meet the requirements, it will be difficult to assemble. At present, there is no Inspection tool for detecting the installation accuracy and machining accuracy of the first section of the crawler chain
