Description
Technical Field
The utility model belongs to the technical field of machining, concretely relates to friction weld frock that welding adds long joint.
Background
The heavy weight drill rod product for oil drilling is composed of an internal thread joint, a pipe body and an external thread joint through welding. Along with the requirement of customers on the length of the joint is longer and longer, the joint is overhung out of equipment too long when a conventional welding tool is used, so that the problems of overlarge equipment vibration, influence on welding quality, reduction in machine tool precision and the like are easily caused.
Disclosure of Invention
In view of this, the utility model aims at providing a friction weld frock that welding extension connects realizes the friction weld who adds the extension joint effectively, solves the equipment vibration that appears when current frock welding, problem that welding quality is low.
In order to achieve the purpose, the technical scheme is as follows:
a friction welding tool for welding an extended joint comprises a spring clamping block arranged on the rotating end of a machine tool, a cushion block is arranged inside the rotating end of the machine tool, a clamping tool is clamped on the inner wall of the spring clamping block, and the cushion block and the clamping tool are arranged at the same axial line position;
a conical curved surface is processed at the contact position of the inner wall of the cushion block and the chamfer angle of the lengthened joint and is used as a positioning surface of the lengthened joint;
the clamping tool comprises a plurality of clamping blocks of tile-shaped structures, the clamping blocks are spliced to form the clamping tool, a fixing belt connected with the spring clamping block is arranged on the waist portion of the outer wall of each clamping block, the clamping blocks penetrate through the fixing belt through bolts to be fixed on the spring clamping block, and one end of each clamping block is exposed out of the spring clamping block.
As a further improvement of the present invention, the inclined angle of the conical curved surface is 45 °.
As a further improvement, the length of the end of the clamping block exposed out of the spring clamping block is 90mm.
The utility model has the advantages that:
(1) The cushion block is provided with a 45-degree inclined surface according to the chamfer size of the threaded end of the joint, the inclined surface and the chamfer surface are matched to serve as a positioning surface of the joint, and compared with a conventional cushion block which needs a threaded end surface as a positioning surface, the length of the suspended joint is shortened, so that the vibration of the joint during welding can be reduced;
(2) The clamping block is lengthened according to the length of the joint hanging-out equipment, and the lengthened design of the clamping block is beneficial to reducing the vibration of the joint under the condition that the joint rotates at a high speed during welding;
(3) The tool expands the processing range of equipment, obviously reduces the vibration of the equipment in the process of processing the lengthened joint, and improves the welding quality.
