The invention relates to the technical field of sealant testing, in particular to sealant fatigue resistance testing equipment which comprises a first concave plate, a clamping piece, a second electric cylinder, a transverse rod, a guide rod, a rack, a local gear, a rotating ring plate and a fixing plate. A plurality of sealant workpieces are respectively clamped in the first concave plate and the clamping piece; The second electric cylinder drives the transverse rod and a guide rod to move left and right, the rack is pushed to move front and back, then the local gear and the rotating ring plate are driven to rotate back and forth around the fixing plate, and a first tension adjusting piece is driven to do reciprocating motion close to the clamping piece and away from the clamping piece; and according to the invention, repeated pulling force application and pulling force elimination are carried out on the sealant workpiece, fatigue resistance testing is realized, and the working efficiency of testing is improved by simultaneously carrying out a plurality of workpieces.
Description
technical field [0001] The invention relates to a sealant fatigue resistance testing device, which belongs to the technical field of fatigue resistance testing. Background technique [0002] The common sealant fatigue tester is generally composed of a servo machine, a tensile mechanism and a control system, which can perform rapid loading, unloading, and reloading continuous cycle fatigue tests within a certain load range. [0003] Chinese Patent Publication No. CN105486599B is a building sealant anti-fatigue test equipment in which the two clamps are reversely stretched to realize the anti-fatigue test of the sealant clamped on the two clamps, and then the structure is changed once Only one piece of sealant can be tested, the work efficiency is low, and the control of the tensile force of the sealant cannot be smoothly adjusted according to the needs, and the flexibility of use is poor. Contents of the invention [0004] Aiming at the problems in the prior art, the inven...
