Abstract

The invention discloses a special fixture for a hydraulic experiment of a cylinder type part with threads at two ends, relates to a special fixture, and particularly relates to a special fixture for ahydraulic experiment of a cylinder type part with threads at two ends. The problem that currently no fixture is special for a hydraulic experiment of a cylinder type part with threads at two ends issolved. The special fixture comprises a first screwed plug, a connecting pipe, a second screwed plug, a plurality of first bolts, a plurality of second bolts and a flange plate; and one end of a workpiece is connected with the first screwed plug, the other end of the workpiece is connected with the second screwed plug, the connecting pipe is installed on the second screwed plug and located in theother end of the workpiece, the second screwed plug is connected with the flange plate through the multiple first bolts, and the flange plate is connected with hydraulic equipment through the multiplesecond bolts. The invention belongs to the field of machining.

Description

technical field [0001] The invention relates to a special fixture, in particular to a special fixture for hydraulic testing of threaded cylinder parts at both ends, and belongs to the field of mechanical processing. Background technique [0002] Usually pressure test equipment, one uses water as the medium, and the other uses air as the medium. The scope of use is different. The water pressure is generally used to test the pressure resistance performance, and the air pressure is generally used to test the airtight performance. [0003] The workpiece is a cylindrical part threaded at both ends. After the workpiece is processed, the pressure test should be carried out on the workpiece according to the design requirements, that is, the strength test and the tightness test. Generally, the hydraulic test is used. The procedures, steps and methods of the hydrostatic test are as follows: 1. Connection: Connect the workpiece with a special fixture to ensure that the thread is firmly...
