Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting equipment, and more specifically to a carrier introduction mechanism which is convenient for press-fitting. Background Art

[0002] Three-way catalysis refers to the process of converting harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The carrier component of the three-way catalytic converter is a porous ceramic material installed in a special exhaust pipe.

[0003] Based on the above, the inventors have found that: when installing the three-way catalytic converter carrier, the traditional method is to press the carrier directly into the workpiece. Due to the lack of a certain guiding mechanism, the carrier cannot be accurately aligned with the workpiece, and position deviation is likely to occur during the pressing process, which leads to difficulties in installing the carrier. In severe cases, it may cause damage to the three-way catalytic converter carrier. Therefore, in view of this, the existing structure is studied and improved, and a carrier introduction mechanism that is easy to press-fit is provided, in order to achieve a more practical purpose. Utility Model Content
