technical field
[0001] The invention relates to the technical field of riveting equipment, in particular to a volute oil guiding groove positioning device and a riveting system. Background technique
[0002] TOX riveting technology is a rivetless riveting technology, which can complete the connection of two or more layers of plates of the same or different materials, and the thickness of the plates can be the same or different. Under the same conditions, the static connection strength of TOX single point is 50%-70% of spot welding, and the double point is the same as spot welding.
[0003] Oil and water will accumulate in the volute of the range hood during use. In order not to affect normal use and facilitate cleaning, the oil and water need to be discharged. Therefore, there are oil drain holes and oil guide grooves at the bottom of the volute; The oil groove is generally welded or riveted on the volute. When the existing oil guide groove and the volute are riveted, ther...
