AI Technical Summary

Technical Problem

Existing truss structure positioning and clamping devices require manual operation, which is inconvenient. Electric clamping methods are prone to damaging the truss and the pressure sensors are prone to failure, making it difficult to meet the requirements of low cost, high quality and short delivery time in modern manufacturing.

Method used

It adopts a clamping method that uses friction wheels and friction parts. The friction wheel is driven by a drive motor to rotate, and the clamping block is brought closer by friction. Stable clamping is achieved through a transmission structure and adjustment mechanism. It can adapt to different specifications of trusses. It is equipped with compression springs and adjustment screws to ensure friction stability and wear compensation.

Benefits of technology

It achieves an automated and stable truss clamping process, avoids clamping damage, adapts to irregularly shaped trusses, and meets the high-efficiency positioning and clamping needs of modern manufacturing.

Abstract

This utility model discloses a truss structure positioning and clamping device, relating to the field of clamping equipment technology. It includes a supporting base plate, a supporting frame, clamping blocks, a drive motor, and a reciprocating transmission assembly. The reciprocating transmission assembly includes a friction wheel and two friction parts. The friction wheel is coaxially fixed to the output end of the drive motor. Both friction parts are horizontally slidably mounted on the lower end of the supporting base plate, and each friction part contacts the opposite side of the friction wheel. The two friction parts are fixed to the clamping blocks. This utility model utilizes the cooperative arrangement of the friction wheel and friction parts. The rotating friction wheel uses the friction between itself and the friction parts to move the two friction parts towards each other, thereby bringing the two clamping blocks closer together until the two clamping blocks clamp the truss. Even if the drive motor continues to drive the friction wheel to rotate thereafter, because the friction between the friction wheel and the friction parts is constant, the clamping force transmitted from the friction parts to the clamping blocks on the truss remains almost unchanged, making it unlikely to damage the truss.
