Abstract

The invention discloses a concentric drilling tool hole-reaming sleeve component assembling tool and method. The assembling tool comprises a connecting plate, an upper pressing die and a hole-reamingsleeve positioning ring, and the connecting plate is fixedly connected with a hydraulic cylinder of a pressing machine; the upper pressing die is connected with the lower end face of the connecting plate, and a guiding conical face is arranged on the inner side face of the lower end of the upper pressing die; and the hole-reaming sleeve positioning ring is arranged on a pressing machine base located under the upper pressing die, the central axis of the upper pressing die and the central axis of the hole-reaming sleeve positioning ring coincide with the central axis of the hydraulic cylinder, and it is guaranteed that when the hydraulic cylinder of the pressing machine presses downwards, a pipe shoe is linearly pressed downwards along the central axis and arranged on the hole-reaming sleevein a sleeved mode. The concentric drilling tool hole-reaming sleeve component assembling tool is simple in structure and convenient to use, the machining process of all parts of the assembling tool is simple, the equipment investment cost is low, industrial large-scale production and use are facilitated, and assembled hole-reaming sleeve components are good in mechanical performance.

Description

technical field

[0001] The invention relates to the assembly technology of reaming sleeve components, in particular to a reaming sleeve assembly assembly tool for a concentric drilling tool and an assembly method thereof. Background technique

[0002] Concentric drilling tools are usually composed of a heel tube, a central drill bit, a reaming sleeve, a pipe shoe, and alloy teeth, among which the reaming sleeve is covered with alloy teeth to ream the hole; The pipes are connected; the alloy teeth are used to impact and break the rock formation, and the reaming sleeve is embedded in the pipe shoe to form a reaming sleeve assembly.

[0003] CN105921630A discloses an assembly process of a reaming sleeve assembly of a concentric drilling tool. Firstly, the pipe shoe is processed into shape, the inner hole of the reaming sleeve is reserved, and the connecting part of the pipe shoe is set outside the connecting part of the reaming sleeve. Heat the pipe shoe and reaming sleeve tog...
