Description

Technical Field

[0001] This utility model belongs to the field of AGV wheel assembly tooling technology, and more specifically, it relates to a forklift mechanism for assembling AGV support wheels. Background Technology

[0002] In the AGV industry, complete machines are generally solution-based products, mainly developed according to the customer's usage scenario. They belong to the non-standard customization field, and there are basically no mass-produced AGV complete machines. In the current technology, most AGV complete machine manufacturers adopt the following assembly method: use support fixtures to support the AGV frame. The support fixtures are about 700mm high. Operators assemble support wheels, contact edges and other mechanical materials at the bottom of the support fixtures, and assemble the electronic control system and related safety obstacle avoidance components at the top.

[0003] However, the above-mentioned support fixture has the following drawbacks: the working space under the support fixture is relatively narrow. When assembling the support wheel, two operators are required to work together. One operator holds the support wheel while the other uses a wrench to assemble the support wheel to the bottom of the AGV frame. This results in high labor intensity and low work efficiency. In addition, some larger support wheels weigh around 50 kg, which cannot be held by one operator alone and requires two operators to hold them together. As a result, three operators are required to assemble the support wheel at the bottom of the fixture, making the assembly operation very difficult. Utility Model Content
