Abstract

The present invention provides a cylindrical shape automatic riveted-joint apparatus which riveted joints a screen drum U-shaped loop with a screen bar in manufacturing a pressure screen. The apparatus is mainly used for solving problem of micro deformation caused by welding the screen drum U-shaped loop with the screen bar in the prior art. The apparatus comprises a transmission pair composed bya bidirectional leading screw and a positioning block nut, the positioning block nut is fixed on an outer wall of a main body through a guide rail and a support, a positioning block guide rail and a positioning block are arranged on the positioning block nut, a pneumatic-rivet gun nut is fixed on an inner wall of the main body through the guide rail and the support, the pneumatic-rivet gun nut and the bidirectional leading screw comprise the transmission pair, the pneumatic-rivet gun is arranged on the pneumatic-rivet gun nut through the pneumatic-rivet gun positioning block and the guide rail; an U-shaped loop positioning rule holder is arranged on the outer wall of the main body of the riveted-joint apparatus, an U-shaped loop limiter is arranged on the U-shaped loop positioning rule holder through the U-shaped loop positioning rule and a slide block, the U-shaped loop limiter is arranged on a slide block holder of an U-shaped loop limiting pile through the U-shaped loop limiting pile and the slide block. The apparatus has advantages of processing circumference riveted joint automatically and no deformation.

Description

Technical field: [0001] The invention relates to a device for riveting a U-shaped ring of a screen drum and a screen bar when manufacturing a pressure screen for papermaking equipment. Background technique: [0002] At present, when manufacturing pressure screens at home and abroad, the U-shaped ring of the screen drum and the screen bars are mostly welded together. The disadvantage is that welding heating causes slight deformation, which affects product accuracy. Invention content: [0003] The technical problem to be solved by the present invention is to provide a cylindrical automatic riveting device for riveting the U-shaped ring of the screen drum and the screen bars together when manufacturing the pressure screen. [0004] The purpose of the present invention is achieved in this way: it includes a two-way lead screw, the two-way lead screw and the positioning block nut form a transmission pair, the positioning block nut is installed on the guide rail, the guide rail ...
