Description

TECHNICAL FIELD

[0001] The application relates to the technical field of high-precision processing of gas wall-hanging stove parts, and particularly relates to a high-precision processing device for gas wall-hanging stove parts. BACKGROUND

[0002] The gas wall-hanging stove is a high-efficiency and energy-saving household heating device, and a burner for mixing and igniting gas and air in the gas wall-hanging stove is also called a fire grate. A plurality of groups of fire grate pieces in the form of a harmonica are usually installed in the fire grate, and the fire grate piece is usually formed by welding a symmetrical split metal shell and a nozzle in the metal shell.

[0003] In the prior art, the fire grate piece welding process usually adopts a man-machine cooperative operation mode, and the operation mode is as follows: first, the pair of metal shells forming the fire grate piece are assembled manually, and then the nozzle is positioned and placed in the inner cavity of the metal shell, finally, the assembled fire grate piece is positioned and fed to the rotary disc conveying equipment to realize work station conversion, and the multi-stage welding of the fire grate piece is realized by synchronously cooperating with the welding equipment and the automatic unloading of the welded fire grate piece is realized by cooperating with the mechanical clamping jaw, so that the batch continuous processing of the fire grate piece is realized.

[0004] However, the traditional man-machine cooperative operation for welding the fire grate piece has the following problems: 1. In the prior art, although the rotary disc conveying equipment, the welding equipment and the mechanical clamping jaw can realize automatic multi-stage welding and unloading of the fire grate piece, the front end still needs to be assembled and fed manually, so that the operation rhythm of the whole equipment needs to be coordinated with manual operation, resulting in low operation efficiency of the whole equipment, long idle time, limited production capacity of the fire grate piece, heavy work burden of the workers and high labor cost, and the workers are also prone to mechanical injury; 2. In the prior art, the rotary disc conveying equipment for conveying the fire grate piece generally needs to be arranged in a ring shape, but due to the requirement of the rotation radius of the rotary disc conveying equipment and the spacing of the work stations, a large amount of invalid space will be formed in the central region of the rotary disc conveying equipment, resulting in waste of space resources, and since the multi-stage welding equipment needs to be arranged along the outer edge of the rotary disc, a device maintenance channel and a safety isolation zone need to be reserved, so that the space occupied by the whole equipment is further expanded, resulting in high space cost of the whole fire grate piece welding process.
