Plastic shell strength testing device

Abstract

The invention relates to a plastic shell strength testing device. The plastic shell strength testing device comprises a box body and a testing mechanism installed in the box body, wherein the testingmechanism comprises a motor, an impact element driven by the motor and a clamping element used for clamping a plastic shell, the clamping element further comprises a transverse moving arm and a vertical moving arm, the vertical moving arm clamps the plastic shell, the vertical moving arm is installed on the transverse moving arm and can move vertically relative to the transverse moving arm, and the transverse moving arm can transversely move relative to the box body. The plastic shell strength testing device is accurate and safe to test.

Description

technical field [0001] The invention relates to a testing device for the strength of a plastic case. Background technique [0002] At present, in order to test the impact strength of the plastic case, a lead ball with a fixed weight (500g, 2000g) is generally used for normal temperature impact, and it is freely dropped from a height of 1.8m to impact the corresponding position of the plastic case shell. The problems of this method are: when the shot ball falls freely, the impact position cannot be accurately grasped, and the test point often deviates, which affects the test result; the impact area cannot be determined during impact, that is, there is no standard impact head, and the test method has no standard, which is easy to produce poor tests. The results are different; the shot ball will rebound after falling from a height of 1.8m and impacting the plastic case, which has certain safety hazards. At present, there is no better method or device to replace it. Contents o...
