The invention provides an opposite horn producing device based on an automatic induction pressure gauge machine. The opposite horn producing device based on the automatic induction pressure gauge machine comprises a workbench and a press-fitting device. According to the opposite horn producing device based on the automatic induction pressure gauge machine, due to the fact that four upper movable blocks are arranged in a radial shape based on the press-fitting device; four lower movable blocks are correspondingly arranged on the lower end face of the press-fitting device, the novel structure ismade distinct, and combined fixing for a horn is more reasonable; due to the fact that a fixing plate is arranged into an arc shape with an opening facing the press-fitting device; a fixing block isin a rubber arc shape equal to that of the fixing plate, and the fixing block and the fixing plate are fixedly connected; when the novel structure works, fixing of the horn has certain buffering performance, and no damage can be caused; due to the fact that the sum of the length of the lower movable blocks and the maximum length of a built-in spring is equal to 2/3 of the length of a fixed slide groove, a positioning rod is located at the upper ends of the upper movable blocks, and a threaded rod is arranged at the lower ends of the lower movable blocks, when the novel structure works, an upper shell and a lower shell of the horn are connected smoothly.
