Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of testing devices, in particular to a ball drop impact testing machine. Background Art
[0002] The ball drop impact testing machine is applicable to the impact strength testing of products such as plastics, ceramics, acrylic, glass, lenses, and hardware. During operation, the test product is placed on the test bench, and the drop key is pressed. The steel ball falls freely and impacts the test sample. The steel ball with a specified weight is freely dropped from a specified drop height onto the product to impact the product, and then the appearance and various performances of the product are checked. However, for the existing ball drop impact testing machines, the height of the steel ball is mostly adjusted manually by workers, which is not easy to operate and has low adjustment efficiency. Moreover, the traditional ball drop impact tester does not have a timely protection mechanism. When the worker's reaction is slow, the rebounding ball will continue to impact the surface of the test sample, resulting in the invalidation of this detection. Content of the Utility Model
[0003] The purpose of the utility model is to provide a ball drop impact testing machine to solve the technical problems in the background art.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

The first main body is provided with a first accommodating groove with an opening in the direction close to the second clamping arm and communicates with the second clamping arm. The first clamping arm and the second clamping arm contact to form a box body with an open top for accommodating the impact ball.
