Claims
- 1. An arrangement for assembling vacuum tube bases comprising: continuously moving chain conveyor means, rotors each provided with a respective group of actuating means, each of said actuating means performing a different one of assembling operations comprising moving bases into clamps, shaping of electrodes and bases, flattening end bending of electrode ends, clamping cathode with electrode bent ends, oxidixing of cathodes; clamp means attached to links of said chain conveyor means in a cantilevered manner for receiving, holding and transporting bases from one rotor to another; stationary former means each arranged in proximity to a respective group of actuating means to cooperate therewith and to actuate said actuating means for performing respective assembling operations in the process of interaction with bases; chain conveyor means for discharging assembled bases, said rotors being in the form of sprockets formed by two rigidly interlinked toothed discs and disposed intermediate of fixed upper and lower plates, groups of actuating means each performing one of assembling operations arranged on rotors and interacting with clamp means holding bases and arranged on the chain conveyor means both on the outer side and inside of a sprocket through holes in said discs, actuating means for cathode oxidixing and containing a vessel for a suspension, mixer means in the form of a cone, spatula means for applying the suspension onto a cathode, and auxiliary former means for imparting reciprocal movement to said mixer means and said spatula means.
- 2. An arrangement as claimed in claim 1, wherein said endless chain conveyor means engages all sprockets, at least two of said sprockets being driving sprockets and kinemtically linked with drive means, the remaining sprockets being driven ones, movement being imparted to said driven sprockets from the chain conveyor means actuated into movement by said driving sprockets.
- 3. An arrangement as claimed in claim 1, wherein said rotors disposed intermediate said fixed plates are biased with respect to one another, the endless chain conveyor means being in form of a zigzag contacting said sprockets both on the outer and inside sides.
- 4. An arrangement as claimed in claim 1, including through holes in the discs of said sprockets, said clamp means of said conveyor means being disposed therebetween, the holes in a top one of said discs accomodating spring-loaded rods each having one end interacting with a former means, the other end of said rod interacting with clamp means enabling it to be lowered, holes in a bottom one of said discs being a passage therethrough of said bases.
- 5. An arrangement as claimed in claim 1, wherein said sprockets are disposed intermediate of said fixed plates with said former means interacting with said clamp means disposed on the top plate, said former means interacting with said actuating means disposed on the bottom plate.
- 6. An arrangement as claimed in claim 1, wherein the actuating means for oxidizing cathodes has vessels for a suspension, mixer means made in the form of cones reciprocating up and down and arranged with a clearance inside said vessels, spatula means for applying said suspension into a cathode, former means having a corrugated portion of reciprocating the mixers for mixing said suspension, and a flat portion to withdraw said spatula means for said vessel when applying said suspension onto a cathode.
