Multi-functional fixing rack for welding test piece

Abstract

The invention discloses a multi-functional fixing rack for a welding test piece. The multi-functional fixing rack for the welding test piece comprises a bottom plate, a column which is fixed on the bottom plate, a T-shaped sleeve which is matched with the column and is fixed on the upper part of the column by a first fastening bolt, and a three-way pipe which is sleeved on the column and the T-shaped sleeve, wherein the three-way pipe is fixed on the column or T-shaped sleeve by a second fastening bolt, and a 45-degree pipe butt welding auxiliary rack is arranged at one end of the T-shaped sleeve; and an pipe plate angle welding auxiliary rack and a pipe horizontal butt welding auxiliary rack are arranged at the other end of the T-shaped sleeve, and the three-way pipe is provided with a transverse plate welding auxiliary clamp. The multi-functional fixing rack for the welding test piece realizes multi-position conversion, is very convenient to disassemble, carry and store, and has a lower manufacturing cost.

Description

Technical field [0001] The invention relates to a welding auxiliary tool, in particular to a fixing frame for a multifunctional welding test piece. Background technique [0002] The "Examination and Management Rules for Welders of Boiler, Pressure Vessel and Pressure Pipeline" promulgated by the State Administration of Quality Supervision, Inspection and Quarantine has been implemented since October 1, 2002. The form of the test piece and the welding position of the test piece have been greatly changed compared with the "Regulations for the Examination of Boiler and Pressure Vessel Welders" promulgated by the Ministry of Labor and Human Resources in 1988. The test piece welding racks usually used in welder examinations are all single-function or less-function. Its main structure is to fix a column on the bottom plate, and an extension arm and a chuck are provided on the column. The workpiece is clamped in the clamp. On the head, the extended arm can only be raised and lowered ac...

AI Technical Summary

Problems solved by technology

The test piece welding frames usually used in welder examinations are all single-function or less-functional. On the head, the extension arm can only be raised and lowered according to the height of the person. If you want to perform welding work in other positions, you need to replace the welding frame or the parts on the welding frame. Not only the operation is troublesome, but also the production cost is high and the production cycle is long Long, difficult to pile up in the assessment site
