Problems solved by technology

Due to the heavy weight of the lead cone itself, and it will be deformed due to impact extrusion during the impact process, if it is not fixed firmly, it will affect the implementation of the test. Therefore, how to securely fix the plumb weight is the prerequisite for the successful implementation of the impact test.
At the present stage, bonding is usually used to fix the lead vertically on the mounting surface. When flexible glue is used, the lead cone will easily slip or fall off after a long time, which will affect the smooth progress of the test and even cause accidents and dangers; When using super glue, it will make it difficult to replace the plumb weight after the impact test, and the residual glue is difficult to remove, which will affect the next impact test

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] The present invention designs a lead cone fixing device for horizontal impact tests, and its structural schematic diagram is as follows figure 1 shown.

[0016] There are mounting holes on the mounting surface of the waveform generator, combined with figure 2 The test process is shown as follows:

[0017] 1. Before the horizontal impact test, install and fix the lead cone on the installation surface through the thin end of the step pin protruding from the installation surface;

[0018] 2. During the test, the lead cone will be subjected to the impact force from the impact table body and the test piece, and will be deformed under the action of the impact force. At the same time, the step pin is completely pressed into the installation hole by the impact force, so that It is automatically separated from the deformed lead cone, so that the plumb bob f...

Abstract

The invention belongs to the field of mechanical structure design, and relates to a plumb bod fixing device for a horizontal impact test. The invention provides a mode to realize the fixing and falling of a plumb bod, wherein the mode is characterized in that a mounting hole is formed in a mounting face of a waveform generator, and an automatic reset mechanism is mounted in the mounting hole. Thefixing device not only can avoid the problems that the plumb bod slips and the residual glue is difficult to remove caused by usual adhesion and mounting mode, but also can realize that the plumb boddeforms after the impact test and automatically separates from the mounting table board, furthermore, the fixing mode is easy to operate, and the rapid and sound replacing and mounting of the plumb bod is realized.

Description

technical field [0001] The invention belongs to the field of mechanical structure design and provides a lead cone fixing device for horizontal impact tests. Background technique [0002] The impact test bench generally uses lead cones to generate the peak sawtooth wave waveform, while the lead cones used in the horizontal impact test need to be mounted on the mounting surface of the vertical waveform generator. Since the lead cone itself is heavy, and it will be deformed by impact extrusion during the impact process, if it is not fixed firmly, it will affect the implementation of the test. Therefore, how to securely fix the plumb weight is a prerequisite for the successful implementation of the impact test. At the present stage, bonding is usually used to fix the lead vertically on the mounting surface. When flexible glue is used, the lead cone will easily slip or fall off after a long time, which will affect the smooth progress of the test and even cause accidents and dange...
