Abstract

The invention relates to an agricultural machine transverse transmission rod limiting support welding device and a welding positioning device thereof. The agricultural machine transverse transmissionrod limiting support welding positioning device comprises a machine frame, a shaft part positioning seat is arranged on the machine frame, and a shaft part positioning structure is arranged on the shaft part positioning seat; an arc part positioning seat is further arranged on the machine frame, and a positioning piece and a stop positioning structure are arranged on the arc part positioning seat;and the welding positioning device further comprises a pressure contact driving mechanism, a shaft part feeding mechanism and an arc part feeding mechanism, wherein the shaft part feeding mechanism and the arc part feeding mechanism are arranged on the machine frame, and an in-place controller is arranged on the arc part feeding mechanism. The shaft part and the arc part are accurately conveyed to the shaft part positioning seat and the arc part positioning seat correspondingly, the shaft part positioning structure is used for positioning the shaft part, a positioning pin and the positioningpiece are used for positioning the arc part, the pressure contact driving mechanism applies acting force on the shaft part and / or the arc part to enable the shaft part and the arc part to be close toeach other, and finally, the arc part and the shaft part are welded through a welding mechanism. In this way, the positioning precision of the shaft part and the arc part is greatly improved, and thewelding efficiency is also improved.

Description

technical field [0001] The invention relates to a welding device for a limit bracket of an agricultural machinery transverse transmission rod and a welding positioning device thereof. Background technique [0002] Agricultural machinery cross drive rods are used in the power transmission of modern agricultural machinery, most commonly found in tractors and agricultural implements, or used in the power transmission between the power output and input ends of the agricultural machinery itself, so that the agricultural machinery can achieve a normal working relationship , and the limit bracket applied to the horizontal transmission rod of agricultural machinery plays an important role in the installation limit of the horizontal transmission rod of agricultural machinery. Such as figure 1 As shown, the limit bracket of the horizontal transmission rod of agricultural machinery mainly includes the shaft part 2 and the arc part 7 arranged at the end of the shaft part 2. The arc par...

Problems solved by technology

[0003] The shaft part and the arc part of the limit bracket are connected by welding. When the limit bracket is mass-produced in the factory, the welding between the shaft part and the arc part needs to be precisely positioned to achieve accurate welding of the two. Specifically, In the prior art, when welding the shaft part and the arc part, the shaft part and the arc part need to be positioned first, and then the welding is performed manually after the positioning is completed. After the welding is completed, the limit bracket is removed, and then the lower A group of shafts and arcs are positioned separately, and manually welded, followed by mass production of limit brackets. This will cause low processing efficiency due to high manual participation in the actual production process, and manpower is invested in production. At the same time, since the shaft and arc are manually positioned, there will inevitably be some errors in positioning accuracy, which results in poor consistency of the produced limit brackets, and manual welding has large welding deformation, Low strength, easy to crack and other bad phenomena
