Embodiment
[0029] like figure 1 and figure 2 As shown, the automobile door sealing strip durability test device includes a base 1 and a power mechanism, and two support columns 2 are fixed on the base, and the upper and lower two sides that can bite and clamp the automobile door sealing strip are arranged opposite to each other on the support column. The clamp, wherein the upper clamp 3 is fixed to the support column, and the lower clamp 4 is slid along the axial direction of the support column, and the power mechanism drives the two clamps to engage through the cam mechanism.
[0030] The power mechanism is a servo motor 5, and the cam mechanism includes an eccentric wheel 6 fixed to the output shaft of the servo motor and a follower 7 fixed to a clamp. The rotation of the eccentric wheel pushes the corresponding clamp to reciprocate along the support column. An upper fixture and a lower fixture are arranged on the support column, and the upper fixture is fixed to the support column. ...

The invention provides a durability testing device for an automobile door sealing strip, which comprises a base and a power mechanism, and is characterized in that the base is fixed with a plurality of support columns, two clamps capable of engaging and clamping the automobile door sealing strip are oppositely arranged on the support columns, one of the clamps is fixed with the support columns, the other clamp is slidably arranged along the axial direction of the support columns, and the power mechanism drives the two clamps to engage through a cam mechanism. The device overcomes the problemsof defects brought about by chain driving and the single test product. The new device is wider in application range and adopts an automatic control system. The device is higher in intelligentization,higher in accuracy and more convenient to operate. The adopted structure is simple to operate, the movement is convenient, and the flexibility is high.
Description
technical field [0001] The invention relates to the technical field of durability testing of automobile parts, in particular to a durability testing device for automobile door sealing strips. Background technique [0002] The door assembly is one of the most frequently used parts in the process of vehicle use, the reliability of the assembly and the performance of related parts are very important. The door seal strip (autodoor rubber seal strip) is mainly used for the fixing, dustproof and sealing of the car door. It is mainly composed of EPDM rubber with good elasticity, compression deformation resistance, aging resistance, ozone, chemical action, and wide service temperature range (-40 ° C ~ +120 ° C) and dense compounding , contains a unique metal clip and tongue buckle, durable and easy to install. It is mainly used in door frames, side windows, front and rear windshields, engine covers and trunk lids to play the roles of waterproof, dustproof, sound insulation, temper...
