Automatic screw rod valve riveting assembling machine

Abstract

The invention relates to valve body assembling equipment, in particular to an automatic screw rod valve riveting assembling machine which comprises a rack, a power distribution control cabinet, as well as a rotary table and a rotary table slicer arranged on the rack and matched with each other, wherein carrier assemblies matched with screw rod valves are arranged on the upper edge of the rotary table at equal intervals; a support shaft fixedly connected with the rack is vertically arranged in the center of the rotary table in a penetrating manner; an upper support disc is fixedly connected with the upper end of the support shaft; a valve tube loading device, a valve tube prepressing device and a valve tube riveting device matched with the carrier assemblies are sequentially arranged on therack in the rotating direction of the rotary table; the valve tube loading device places screw rod valve tubes in the carrier assemblies; the carrier assemblies rotate anticlockwise along with the rotary table and sequentially rotate to the valve tube prepressing device to press the screw rod valve tubes in valve body caps, and the valve tube riveting device carries out riveting on the screw rodvalve tubes and the valve body caps to complete the riveting assembling process of the screw rod valve tubes; and the assembling and positioning precision is high and the sealing effect is excellent.

Description

technical field [0001] The invention relates to valve body assembly equipment, in particular to an automatic riveting assembly machine for screw valves. Background technique [0002] The structure of a screw valve 17 is as Figure 11 As shown, it includes a valve seat 22, the lower end of the valve seat 22 communicates with a lower valve pipe 24, the side communicates with a "Γ"-shaped side valve pipe 19, and the upper end is fixedly connected with a valve body cover 20, the valve body cover The upper end of 20 is riveted with screw valve tube 21 , and the side of valve body seat 20 is provided with side positioning plate 23 . [0003] The existing three-way screw valve is usually manually assembled by the operator, the assembly efficiency is low, and the precision after assembly is poor, resulting in insufficient sealing, affecting the product qualification rate, and further affecting the production efficiency. Contents of the invention [0004] The object of the present...
