AI Technical Summary

Problems solved by technology

At present, the mainstream clamping and positioning scheme is mainly based on the shape and structure of the part itself for positioning and clamping. When processing the peripheral surface of the part, the mandrel is used for positioning. The center positioning hole of the shell cooperates with the outer circle of the mandrel to achieve centering and the shell The hole cooperates with the positioning pin to achieve orientation, and the shell I surface cooperates with the positioning surface to achieve height determination, but because the sizes of the centering hole 01 and the orientation hole 02 are different between different shells, and the distance between the centering hole 01 and the orientation hole 02 Due to the different positional relationship, the supporting positioning mandrel tooling can only be applied to a single product, and cannot be shared by multiple models.

In the automatic production mode, in order to achieve 24-hour unmanned continuous processing of multi-model mixed lines, a large number of mandrel tooling is required. The cost of tooling matching and management is high, which cannot meet the needs of automated production lines.

Therefore, how to design a generalized positioning and clamping method that can meet the positioning and clamping requirements of a series of electromechanical actuator shells, and a universal clamping device that can be quickly replaced has always been a constraint to the multi-model electromechanical actuator shells. Mixed line automatic processing, reducing the technical bottleneck of tooling and management costs
