Automatic welding machine for cutter shaft and tool magazines of rotary cultivator

Abstract

The invention relates to an automatic welding machine for a cutter shaft and tool magazines of a rotary cultivator. The automatic welding machine comprises a main frame; a rotary indexing mechanism, acutter shaft jacking mechanism and a transverse movement mechanism are arranged on the main frame, wherein the rotary indexing mechanism is used for controlling the cutter shaft to rotate, and the transverse movement mechanism can move back and forth in the direction of the cutter shaft; a transverse tool magazine feeding mechanism, a longitudinal tool magazine feeding mechanism and a welding mechanism are arranged on the transverse movement mechanism, wherein the transverse tool magazine feeding mechanism is used for storing and supplying the tool magazines, and the longitudinal tool magazine feeding mechanism is used for pushing the tool magazines to the specified positions of the cutter shaft; and a welding gun capable of adjusting the welding angle is arranged on the welding mechanism. According to the automatic welding machine, the welding requirements of different angles of the welding gun can be met, the tool magazines and the cutter shaft are completely welded, in addition, welding is uniform, the firmness is good, the welding quality can be effectively improved, and the adaptability is wider.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery equipment, and in particular relates to an automatic welding machine for a rotary cultivator cutter shaft and cutter magazine. Background technique [0002] In recent years, with the continuous deepening of agricultural mechanization, rotary tillers have been widely used in land cultivation, and the market demand and annual output are both large. The knife shaft is the main part of the rotary tiller. A certain number of knife magazines are welded on the knife shaft according to a certain rotation angle and spacing, and the rotary tiller is loaded into the knife magazine according to the needs of forward rotation and reverse rotation. [0003] For the welding of the rotary tiller cutter shaft tool magazine, the traditional manual welding method has a huge workload, low efficiency, and the welding quality cannot be guaranteed. In principle, the existing automatic welding machine can ...

[0003] For the welding of the rotary tiller cutter shaft tool magazine, the traditional manual welding method has a huge workload, low efficiency, and the welding quality cannot be guaranteed

In principle, the existing automatic welding machine can realize the welding between the tool shaft and the tool magazine, but most of the welding between the tool shaft and the tool magazine is not uniform, and there are even many gaps left, the degree of firmness is poor, and when it breaks during use happened

This is because the contact surface between the tool magazine and the tool shaft is arc-shaped, and the tool magazine supply device of the existing automatic welding machine cannot smoothly send the tool magazine to the designated position of the knife shaft. At the same time, the angle of the welding torch needs to be adjusted and changed at different positions. The angle of the existing automatic welding machine welding torch is generally fixed, which cannot meet the technological requirements of the angle change during welding. At the same time, a large number of manual assistance is required in welding.
