Problems solved by technology
[0004] The bullet chain is used to fix the fireworks bombs. The bullet chain can fix a large number of fireworks bombs in series, which is convenient to use and easy to carry. Most of the bullet chains are made of steel; the bullet chains are equipped with clips to fix the fireworks bombs , The magazine is used to hold the fireworks bomb. The magazine is made of elastic steel, and the fireworks bomb is mostly made of non-magnetic materials such as paper. The size of the holding force, the clamping force of the magazine should be moderate. If the clamping force is too small, the shells will easily fall from the magazine during the transportation and shaking, which will easily cause accidents. If the clamping force is too large, the fireworks will fall off. The loading and unloading of the ammunition is difficult and inconvenient to use
[0005] In the prior art, there is no automatic test device for clip performance, which is used to measure the clamping force of the clip on the bullet chain

The invention discloses a shell clip performance auto-test device and a control method thereof. The shell clip performance auto-test device comprises a workbench; a clamp to fix a shell chain is arranged on the workbench; a clamping force detection mechanism is also fixed onto the workbench and includes a screw nut mechanism; a nut of the screw nut mechanism is arranged on the workbench in front-rear sliding manner; a screw of the screw nut mechanism is rotationally arranged on the workbench and is connected with a driving device; a force measuring device is fixedly connected to the front endof the nut of the screw nut mechanism; the driving device drives the screw to rotate forwardly and reversely; when the nut slides forward, the force measuring device pushes a fake shell on a shell clip to slide, thereby measuring clamping force of the shell clip. The shell clip performance auto-test device provided herein is used for measuring clamping force of a firework shell on a shell chain and providing clamping force test data for a user so that it is convenient for the user to detect whether the clamping force of the shell clip on the shell chain is qualified.
Description
technical field [0001] The invention relates to the technical field of fireworks bombs, in particular to an automatic testing device for the performance of a magazine clip and a control method thereof. Background technique [0002] Firework bombs are a kind of fireworks. After being launched into the air, they burst out with various light colors, flower patterns or other effects. Large-scale performances generally use fireworks bombs and some ground fireworks and small fireworks, but the most important thing to render the scene is the fireworks bombs. [0003] Fixing the fireworks bombs on the bullet chain is neat and convenient for transportation and use, and it is not easy to drop or collide with each other. [0004] The bullet chain is used to fix the fireworks bombs. The bullet chain can fix a large number of fireworks bombs in series, which is convenient to use and easy to carry. Most of the bullet chains are made of steel; the bullet chains are equipped with clips to ...
