Description

Technical Field

[0001] This utility model relates to the field of rotary tiller production, specifically a welding fixture for rotary tiller production. Background Technology

[0002] Rotary tiller blades are an important working component of rotary tillers, frequently used for tilling operations in agriculture. They are characterized by their strong soil-breaking ability and ease of replacement. Because tilling operations easily cause wear on the rotary tiller blades, a wear-resistant layer needs to be welded onto the blade edges during the manufacturing process. Currently, the welding of this wear-resistant layer to rotary tiller blades faces the challenge of rapid and precise clamping, resulting in low welding efficiency and impacting the production efficiency of rotary tiller blades. Utility Model Content

[0009] Preferably, three positioning sliders are provided, and rotary tillage blades are fixedly connected to the upper surface of the positioning sliders.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The feeding device proposed in this utility model can initially clamp and position the rotary tiller blade before welding, restricting it to the running trajectory of the positioning guide groove. During operation, it can quickly move along the positioning guide groove to the welding working position.

[0012] 2. The positioning device proposed in this utility model can quickly position and further clamp the feeding device after it reaches the working position, ensuring that it no longer moves along the positioning guide groove and guaranteeing the accuracy of the clamping operation; the clamping device is driven by a cylinder, which can clamp the rotary tiller blade in the positioning device that has reached the working position more quickly, thereby improving the clamping efficiency.
