In the prior art, sealing strip needs to carry out the test of compression load and compression set before the supply of material.The test of sealing strip compression load and compression set is undertaken by the test fixture of compression load and the test fixture of compression set respectively, complete test procedure need carry out the compression load test earlier, carry out the test of compression set again, then the repeated compression Road test.Therefore, sealing strip needs the dismounting of the sealing strip adapted seat from compression set frock and compression load test fixture repeatedly and installs, and introduced test error to test, and this test error can not be accepted now.
Summary of the invention:
The purpose of this utility model is to provide a kind of sealing strip test fixture, and described this sealing strip test fixture will solve the technical matters that has test error in the test process of sealing strip compression load and compression set in the prior art.
This sealing strip test fixture of the present utility model is by last increased pressure board, following increased pressure board, sealing strip adapted seat and sealing strip applied voltage test piece constitute, described sealing strip adapted seat is fixedly installed on the described increased pressure board down, wherein, the described increased pressure board of going up is provided with following increased pressure board parallel interval, the two ends of following increased pressure board are respectively arranged with screw rod, described screw rod is all perpendicular to the upper side plane that descends increased pressure board, be provided with axial screw in the lower surface of screw rod, be provided with tight fixed bolt in the downside bottom surface of following increased pressure board, the axial screw that described tight fixed bolt is upward through down behind the increased pressure board with the screw rod lower surface is connected, the two ends of last increased pressure board are respectively arranged with through hole, screw rod all is upward through described through hole, the circumference of screw rod all is arranged with a limited block outward, described limited block is all between last increased pressure board and following increased pressure board, be provided with nut on the screw rod of last increased pressure board top, described sealing strip applied voltage test piece is connected with last increased pressure board by securing member.
Further, be provided with the slide block that the cross section is the T type in pressurization version and the down pressurization version on the described sealing strip.
Further, the bottom of described screw rod is provided with screw, guarantees that screw rod is detachable.
Principle of work of the present utility model is: when the test of compression load that carries out sealing strip and compression set begins, sealing strip is installed on the sealing strip adapted seat.When carrying out the compression load test, sealing strip applied voltage test piece is connected on the increased pressure board, sealing strip applied voltage test piece is the pressurized part of simulation sealing strip operating mode, as the exert pressure face of simulation car door frame to sealing strip.Remove nut and limited block from screw rod,, will descend increased pressure board, last increased pressure board or sealing strip applied voltage test piece to be connected, can carry out the compression load test of sealing strip with pressure testing machine perhaps further from descending increased pressure board to remove screw rod.When carrying out the compression set test, remove sealing strip applied voltage test piece, nut and limited block are installed on the screw rod, utilize nut that last increased pressure board is produced pressure, can carry out the compression set test of sealing strip from last increased pressure board.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model is provided with dismountable limited block, screw bolt and nut in the sealing strip test fixture, select to use limited block, screw bolt and nut according to test objective, thereby realized the merging of compression set test fixture and compression load test fixture, in compression set test and compression load test process, sealing strip can remain on the sealing strip adapted seat, need not to dismantle repeatedly and install, reduced test error, improved testing efficiency simultaneously.
