Testing device for rubber body of insert

Abstract

The invention provides a detection device for a rubber body of an insert. The detection device comprises a mounting base for fixing the insert, a push rod capable of pushing the inner-layer piece of the insert to move in the axial direction so as to drive the rubber body to extend out of an outer-layer piece of the insert as well as a first driving device connected with the push rod and driving the push rod to reciprocate, wherein the push rod can be separated from the inner-layer piece. The detection device for the rubber body of the insert realizes detection of the tension performance of the rubber body of the insert under the premise that the insert is not damaged; when the tension performance of the rubber body meets the requirement, the insert can be still used after detection, so that detection damage is avoided, and resource waste is avoided; and meanwhile, the insert is not required to be treated, and the detection efficiency is increased effectively.

Description

technical field [0001] The invention relates to the technical field of testing the tensile performance of rubber bodies of inserts, and more specifically, to a testing device for rubber bodies of inserts. Background technique [0002] In order to meet the functional and mechanical properties of the workpiece, inserts are usually used, that is, other materials are embedded inside and / or outside the workpiece, such as copper inserts, plastic inserts and rubber inserts. [0003] The rubber insert usually includes: an inner layer, an outer layer, and a rubber body arranged between the inner layer and the outer layer, such as a blade insert (the blade insert includes: an inner metal sleeve, an outer metal sleeve and the rubber body arranged between the inner metal sleeve and the outer metal sleeve). For the above inserts, it is necessary to check whether the tensile performance of the rubber body meets the requirements. [0004] At present, the method for testing the tensile pe...
