Abstract
The utility model relates to a wobbler testing apparatus for metal bellows, which comprises a bellows fatigue testing machine, a wobbler structure and a pressure charging structure. The utility model is characterized in that: the wobbler structure is positioned between a door shape framework of the testing machine and a pressure charging cylinder base on a workbench. Two ends of a beam are connected to the pressure charging cylinder base through a socket head screw, a double-head nut, a rod end joint bearing and a bearing support. The rod end joint bearing component is vertically arranged on the beam, one end of the rod end joint bearing component is connected with a terminal disc in the middle of the beam through a lever hinge, while the other end is connected with a collet in the middle of an upper beam of the testing machine framework through a collet hinge. The device can satisfy the limit and pressure charging requirements during testing, and realize the oscillating wobbler requirements of the bellows along a pitch arc; therefore, the utility model is applicable to wobbler tests of the bellows of different specifications.
Description
Technical field
The utility model relates to the equipment that uses in the metallic bellows fatigue life test, a kind of metallic bellows rolling test device.
Background technology
Metallic bellows is a kind of flexible, thin-walled, the tubular parts of transverse wave is arranged.Its existing elastic property has sealing characteristics again, can produce under external force and moment loading axially, angle, side direction and combination displacement thereof, is widely used in many industrial circles, and at present domestic technical standard is mainly observed the regulation of JB/T6169-92.
The fatigue life test of metallic bellows is that corrugated tube is installed on the fatigue tester, and shift reciprocately stops test during to mission life, checks that corrugated tube has or not the fatigure failure phenomenon.Owing to failure symptom occurred in the production application, increasing user proposes the rolling test requirement: promptly under the test pressure of regulation, corrugated tube is swung in certain angular range, reached to test after the mission life of design and stop, checking that corrugated tube has or not the fatigure failure phenomenon.
Rolling test requires the length of corrugated tube to immobilize, and carries out reciprocally swinging after the pressurising in certain angular range, and swinging track is a camber line.And the movement locus of present corrugated tube fatigue tester is a straight line, can't satisfy and wave requirement, does not also see related process report, and domestic still do not have actual tests experience and a specialized equipment.
Summary of the invention
The purpose of this utility model provides a cover metallic bellows rolling test device, both can satisfy the spacing and pressurising requirement in the test, can realize the wave requirement of corrugated tube along the camber line reciprocally swinging again.
The design's metallic bellows rolling test device, comprise the corrugated tube fatigue tester, wave structure and pressurising structure, it is characterized in that waving structure between the door-shaped frame of testing machine and the pressurising cylinder seat on the worktable: the crossbeam two ends are connected on the pressurising cylinder seat by socket head cap screw, double end nut, spherical plain bearing rod end, bearing seat, perpendicular to spherical plain bearing rod end assembly one end of crossbeam setting by lever hinge and crossbeam middle part take over a business to be connected, the other end is connected on the testing machine chuck by the chuck hinge.
Metallic bellows rolling test device is the equipment that increases on the basis of existing fatigue tester, the pressurising cylinder can be changed joint according to the different requirements of air pressure and hydraulic pressure, according to the different corrugated tube specifications and the spherical plain bearing rod end of pressure limit choice criteria, and design parts such as corresponding crossbeam, pressurising cylinder, make this device be applicable to the rolling test of the corrugated tube of different size.
