Abstract

The invention discloses an automatic production line of a seat tray, which is characterized in that a locking mechanism assembling device is used for assembling a torsional spring assembly and a connecting rod on a tray to be assembled at a first assembling station and assembling the torsional spring assembly and the connecting rod on the tray to be assembled at a second assembling station; the threaded rod assembling device is used for assembling the threaded rod onto the tray to be assembled at a third assembling station; the plastic sleeve assembling device is used for hollowly sleeving the threaded rod with a plastic sleeve at a fourth assembling station, the spring assembly assembling device is used for sleeving the threaded rod with a pressure spring, a forming gasket and a flat gasket at a fifth assembling station, and the plastic cover assembling device is used for matching an adjusting nut in a plastic cover with the threaded rod in a threaded manner at a seventh assembling station; the handle assembly device sleeves the adjusting rod with a handle piece at a ninth assembly station; according to the technical scheme, automatic assembly of the seat tray can be achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to an automatic production line for seat trays. Background technique [0002] For existing office chairs and leisure chairs, the reclining function and reclining adjustment are often realized through the seat tray. [0003] The Chinese patent document with the publication number CN201542121U discloses a tray for double-locking chairs, which includes a chassis mounted on a swivel chair. There is a movable seat in the body, and a tapered tube is inserted into the movable seat. There is a tapered fixed plate between the tapered tube and the movable seat. The side wall of the chassis and the shell is connected with an adjusting rod that can rotate and move axially. The inner end of the adjusting rod is plugged into the movable seat and is connected with an adjusting plate that can contact the air pressure bar. [0004] Due to the goodness of its structure, the seat tray ...
