A mechanism for testing bonding strength of lamp brackets comprises an upper member and a lower member. The lower portion of the upper member is provided with a threaded hole used for being fittingly connected with a screw of a part to be tested. The upper portion of the upper member is provided with an upper cavity used for being connected with a fixed body of a testing device. The upper portion of the lower member is provided with a thread fixedly connected with a lower board of the part to be tested, and the lower portion of the lower member is provided with a lower cavity connected with a movable body of the testing device. The part to be tested and the testing device can be conveniently connected, operation is easy, measured data are stable, and reproducibility is high. Reuse can be realized, and cost is reduced. The mechanism is simple and compact in structure, convenient to integrate and standardized in manufacture.
Description
technical field [0001] The invention relates to a mechanism for testing the rubber bonding strength of a lamp bracket. Background technique [0002] The component to be tested - the lamp bracket, consists of an upper plate 1, a rubber body 2, a screw 3, a cavity 4, and a lower plate 5 (such as figure 1 , figure 2 shown). Except that the rubber body 2 is a non-metallic material, the materials of the other parts are all metal parts. The vulcanization manufacturing process is adopted between the rubber body 2 and the upper plate 1 and the lower plate 2, and the three are firmly connected together. [0003] During the use of the lamp bracket, it needs to bear certain load and impact. If there is a problem with the bonding between the rubber and the metal, it may cause the overall failure of the lamp bracket. Therefore, testing the bonding strength between the rubber and the metal of the lamp bracket is an important basis for measuring the quality of the lamp bracket produc...
