Abstract
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
The present invention relates to a kind of lamp bracket rubber bonding strength testing machine structure.
Background technology
Parts to be tested--lamp bracket constitutes (as shown in Figure 1 and Figure 2) by upper plate 1, rubber bodies 2, screw 3, cavity 4, lower plate 5.Except rubber bodies 2 is the nonmetallic materials, the material of remaining parts is metalwork.Adopt the sulfuration manufacturing process between rubber bodies 2 and upper plate 1, the lower plate 2, with firm being linked together between the three.
Lamp bracket in use need bear certain load and impact.If bonding the going wrong between rubber and the metal might be caused the global failure of lamp bracket.Therefore, the rubber of test lamp bracket and the bonding strength between the metal are to weigh an important evidence of lamp bracket product quality.The test of bonding strength has relevant national standard between metal and the rubber, by the data of its specifying measurement, the performance of the use state of reaction measured piece that can only be indirect.The properties data of measured piece in the time of can reacting more near practical application in order to obtain, the necessary technical measures that adopt other.In the past, in order to test this data, the method for use was: in cavity 4, penetrate iron wire respectively and connect with fixed body 7, the mobile 16 of testing apparatus.There is following defective in this method: the disposable use of iron wire, cause waste; Iron wire is connected difficult the grasp and popularization of wasting time and energy with lamp bracket and testing apparatus; Uncertainty when connecting with lamp bracket and testing apparatus because of iron wire and not repeated causes the fluctuation of measured value big, does not have reappearance.
Summary of the invention
The object of the present invention is to provide a kind of for connection lamp bracket and testing apparatus, reusable, convenient connection, can make the stable lamp bracket rubber bonding strength testing machine structure of test result.
Technical scheme of the present invention is: comprise upper member, lower member; Described upper member bottom is provided with the threaded hole that is connected for the screw fit of parts to be tested, and upper member top is provided with the upper plenum that is connected for the fixed body of testing apparatus; Described lower member top is provided with the threaded body that the lower plate with parts to be tested is connected and fixed, and the lower member bottom is provided with the following cavity that is connected with the mobile of testing apparatus.
Described threaded hole axis and upper plenum axis are positioned at same straight line.
Described threaded body axis is positioned at same straight line with following cavity axis.
Also comprise for cooperate the fixedly last connecting rod of fixed body with upper plenum; Described upper member is provided with upper plenum and connects the last mounting hole that is used for installing connecting rod.
Described upward connecting rod is screw.
The described mounting hole axis of going up is vertical mutually with the upper plenum axis.
Also comprise for cooperating the fixedly lower link of mobile with following cavity; Described lower member is provided with following cavity and connects the following mounting hole that is used for installing lower link.
Described lower link is screw.
It is described that the mounting hole axis is vertical mutually with following cavity axis down.
The present invention both can realize that parts to be tested were connected with facility between the testing apparatus; Operation easily simultaneously; Data stabilization, the reappearance height measured; Can reuse, reduce cost.The present invention's compactness simple for structure is convenient to integrated, standardization manufacturing.
