AI Technical Summary

Technical Problem

The existing clipper shear blade locking structure is prone to seal damage and hydraulic oil leakage in high temperature environments, resulting in failure of the locking structure, requiring frequent maintenance, and the scope of application of hydraulic oil circuits is limited.

Method used

The structure of the driving rod and the inclined surface of the locking block is adopted, and the movement of the locking block is achieved through the rotation of the driving rod, instead of the traditional hydraulic cylinder driving, and a cover plate is added to prevent iron filings from entering the sliding chute.

Benefits of technology

It improves the convenience and scope of application of the locking structure, reduces maintenance frequency, extends the service life of the drive rod, and avoids the limitation of the hydraulic oil circuit.

Abstract

The invention provides a flying shear blade locking structure which comprises a blade frame, a shear blade is detachably connected with the blade frame, and a dovetail-tenon-shaped mounting seat is arranged at the lower end of the blade frame; a limiting boss is fixedly arranged at one end of the base; a clamping position for clamping the mounting base is formed between the locking block and the limiting boss, and the end face, away from the clamping position, of the locking block is an inclined face; and the driving rod is rotationally connected with the base, the driving rod is in threaded connection with the locking block, and the driving rod is arranged in the inclination direction of the inclined surface of the locking block. The locking device has the beneficial effects that compared with a traditional mode that a hydraulic cylinder drives the locking block to move, movement of the locking block can be completed by matching rotation of the driving rod with arrangement of the inclined face of the locking block, operation is more convenient and faster, and the application range is wider.
