An automatic welding system and method for comb teeth and small ring parts

Abstract

The invention discloses an automatic welding system and method for comb teeth and small ring parts. Finished welding products of the comb teeth and small rings are used for yarn penetrating of a textile machine. The system is provided with an annular vibration feeder and a spot welder; the spot welder and a linear vibration feeder are arranged on the right side of the annular vibration feeder; the right end of the annular vibration feeder is in seamless connection with a linear vibration feeder; and the right end of the linear vibration feeder is in seamless joint with a welding table which is located under a welding head of the spot welder. When a comb tooth clamp moves leftwards to reach the limit position, the right end of the welding table is in seamless joint with the left end of the comb tooth clamp; a four-phase rotary working table with four table faces is arranged in front of a comb tooth conveyor; the table face closest to the comb tooth conveyor is located at the first phase; a hydraulic propeller is arranged under the table face at the first phase; each table face is provided with a comb tooth material frame; and the comb teeth are stacked into the comb tooth material frames from bottom to top. According to the automatic welding system and method, feeding, welding and discharging of the comb tooth and the small ring parts are organically combined, and automatic welding of the comb teeth and the small ring parts is achieved.

Description

technical field [0001] The invention belongs to the fields of mechanical manufacturing automation and welding automation, and in particular relates to a welding system and method capable of welding comb-tooth parts and small ring parts together. The welded products of comb teeth and small rings are mostly used in textile machinery for yarn threading of textile machines. The welded products of comb teeth and small rings are called threading tension sheets. Comb teeth and small rings are used on every textile machine. There are many of them, and each yarn needs a comb and small ring. Background technique [0002] The yarn threading on the textile machine is realized by the threading tension sheet welded by the comb teeth and the metal small ring. The yarn on the pan head of the textile machine passes through the threading tension sheet to the weaving opening. There is elasticity, otherwise the yarn will break easily. Therefore, the comb teeth are all thin iron sheets, and the...

Problems solved by technology

[0003] At present, in the textile machinery industry, manual welding is used for the welding of such parts. Since the number of comb teeth is at least 10, manual welding is used when welding with the corresponding number of small rings. Long working hours, low production efficiency and low accuracy

And the welding production of this kind of parts belongs to the production method of large batches, and a single product requires many welding points. Therefore, the automatic welding system of this kind of parts is urgently needed in this field to solve the problem of low production efficiency.
