[0002] Hard alloy cutter is widely used in metal processing, woodworking and other high-precision manufacturing fields due to its high hardness, high wear resistance and excellent cutting performance. In order to ensure the service life and cutting performance of the cutter, welding between the hard alloy blade and the cutter body is usually required to form a whole cutter structure. Currently, the welding process of hard alloy cutter mainly relies on manual operation or semi-automatic equipment, which has low welding precision, low efficiency, high labor cost and other problems, and is difficult to meet the needs of modern industrial automation production.

[0003] Traditional hard alloy cutter welding equipment usually adopts single-station or few-station design, and manual feeding, cutter position adjustment and manual cutter removal after welding are required during the welding process. This method not only affects the consistency of welding, but also easily leads to unstable product quality due to manual misoperation. In addition, in the environment of multi-batch and large-scale production, the production capacity of single-station welding equipment is limited, which is difficult to meet the needs of modern manufacturing for high-efficiency automatic welding.

[0004] To solve the above problems, multi-station rotary welding machines have been gradually developed in the industry, and the core feature is to use a multi-station rotary table structure to enable the to-be-welded cutter to rotate to different stations for continuous welding in sequence, combined with automatic feeding, positioning and welding system, to greatly improve the welding efficiency and quality. However, there are still many optimization spaces in the structure design and automation degree of existing multi-station welding equipment, for example:

[0005] Insufficient automation in the welding process: some equipment still needs manual intervention to complete the feeding, positioning or post-welding removal of the cutter, which is difficult to form a fully automated production process.

[0006] Welding precision and consistency are difficult to guarantee: the indexing positioning accuracy of the rotary table is limited, which may cause the cutter welding position to deviate, affecting the final welding quality.

[0009] Therefore, how to design a kind of high-efficiency rotary welding equipment capable of realizing automatic feeding, accurate positioning, multi-station continuous welding and automatic discharging becomes an urgent problem to be solved in the hard alloy cutter manufacturing industry.

[0025] More specifically, as shown in Figure 1 Support seat 1 is the body base, and the whole constitutes the bearing and installation base of equipment;Workbench 2 is fixed above support seat 1, for installing the transmission, rotation and fixture etc. functional components of welding machine. Workbench 2 side is provided with first conveying device 6, and the other side is provided with second conveying device 7, and first conveying device 6 and second conveying device 7 are respectively used to send the hard alloy cutter to be welded and output the cutter welded, and the direction of feeding and discharging can be set according to specific requirements, so that the transmission flow of cutter on workbench 2 is more smooth. The welding process is mainly completed by welding device 3, and the welding device 3 is fixed on workbench 2, which can effectively weld the hard alloy cutter positioned on rotary table 8.

[0026] In the above embodiment, as shown in Figure 1 Rotary table 8 is used in cooperation with rotary pedestal 5, and driving mechanism is arranged in rotary pedestal 5, which can drive telescopic link 51 and gripper 52 installed thereon to rotate and grab. The top of rotary table 8 can be provided with multiple stations according to the shape of cutter and welding requirements, and each station can correspond to welding device 3 when rotating to a predetermined position, to complete the welding operation of hard alloy cutter.

[0027] More specifically, as shown in Figure 1 Telescopic link 51 and gripper 52 jointly constitute automatic grabbing mechanism. The bottom of telescopic link 51 is connected with rotary pedestal 5, and gripper 52 is installed at the end of telescopic link 51. During work, gripper 52 grabs hard alloy cutter from first conveying device 6 through up-down (or front-back) movement of telescopic link 51, and places the cutter to corresponding station after rotary table 8 is indexed in position;After the completion of cutter welding, gripper 52 transfers the cutter to second conveying device 7, to realize the whole automatic feeding, welding and discharging process.
