Embodiment Construction

[0016] Such as figure 2 As shown, the cylindrical single-line rectangular thread of the present invention includes a cylindrical single-line rectangular internal thread 1 and a cylindrical single-line rectangular external thread 2. The thread adopts a cylindrical single-line rectangular thread, and the single-line thread has good self-locking performance; The cylindrical body spirals upwards in the axial direction, and the tooth shape of the axial section is a rectangular concave-convex straight tooth; the tooth flank of the thread is a smooth working screwing sliding surface; the thread of the joint has only a major diameter and a minor diameter without a pitch diameter, so The tooth groove W and tooth crest thickness F of the cylindrical single-line rectangular internal thread 1 are respectively screwed with the tooth top thickness f and tooth groove w of the cylindrical single-line rectangular external thread 2, and the rings are tightly locked. buckle and screw it securel...

Abstract

The invention relates to a connection thread between drilling tool systems of a blasthole drill, and aims to solve the problem of processing of special inch tapered threads of an existing slender-shaft drilling rod: a lengthened lathe with a tilted profiling device is used for processing the thread, and the thread is required to be checked with a special thread ring or feeler gauge, but a general numeric control machine tool cannot be used for processing the thread, so that a certain difficulty in the processing of the thread and inconvenience in user maintenance are caused. The connection thread between the drilling tool systems of the blasthole drill comprises internal and external threads. The connection thread adopts a cylindrical single-line rectangular thread for connection, only has a large diameter and a small diameter without a medium diameter, and is a concave-convex straight tooth with a rectangular axial section taking a tooth shape; the tooth side surface of the connection thread is a working engagement sliding face with a smooth surface; the connection thread adopts small-diameter centered clearance fit. The processing bottleneck of the slender-shaft drilling rod is solved; furthermore, the production period is shortened, and the manufacturing cost is reduced; the precision of the rectangular straight tooth shape is easy to guarantee.

Description

technical field [0001] The invention relates to a threaded joint between the drilling tool systems of a roller-cone drilling rig, which is mainly used for the threaded connection of the joints between the drilling tool systems of the roller-cone drilling rig, and can also be used for the joint threaded connection between the drilling tool systems of the rock drilling machine. Background technique [0002] as attached figure 1 As shown, the threads of the joints between the drilling tool systems used by the roller cone drilling rigs in the existing mines in my country are all special imperial conical threads. It is composed of device, drill string, rod stabilizer and drill bit, and the interconnection between them is a special imperial tapered thread, that is to say, one end of their interconnection is a special imperial tapered internal thread or external thread; processing the Threads need to be machined on a horizontal lathe with a beveling device, and special thread rings,...
