Abstract

The invention discloses manufacture and assembly technology of an annular self-locking lifting hook. The technology comprises following steps: adopting precision casting technology is adopted to cast a lifting ring, a hook body, a lifting hook body, a rough block of a lifting hook lock; eliminating the casting internal stress; removing casting burr and corners by grinding; drilling the lifting ring, the hook body, the lifting hook body, the lifting hook lock, sleeving a lifting hook bolt with an external thread; finishing surfaces of the lifting ring, the hook body, the lifting hook body and the lifting hook lock, performing de-oiling, rust-removing and phosphating operation and spraying plastics with yellow electrostatic powder to surfaces; utilizing No.45 round steel to turn a connecting shaft and a lock shaft with a bluing surface on a lathe; loading the lifting ring to the lifting hook bolt of the lifting hook body, adding a spring cushion, screwing a locking nut; employing the connecting shaft to assembly the lifting hook body and the hook body together; riveting the connecting shaft; and utilizing the lock shaft to load the lifting hook lock to the upper end of the side surface of the hook body. The manufacture and assembly technology of the annular self-locking lifting hook has following beneficial effects: manufacture quality of parts and requirements of products can be ensured.

Description

The manufacture packaging technology of ring type self-locking hook

Technical field

The present invention relates to the manufacture packaging technology of the rigging ring type self-locking hook that the industries such as a kind of applicable mining machinery, shipbuilding navigation use.

Background technology

Self-locking hook is not belonging to seriation and standard series product, and belong to product that is special special or that establish one's own system, so the manufacturing of parts is all unicity, particularity, this manufacturing just determining parts all must have its special manufacturing process, is otherwise it cannot be guaranteed that the function of the prescription of product and product.

Summary of the invention

In order to solve problem set forth above, the present invention provides the manufacture packaging technology of a kind of ring type self-locking hook, the manufacture packaging technology of this ring type self-locking hook, it is possible to ensure workmanship and the product requirement of parts.

The object of the present invention is achieved like this, the manufacture packaging technology of ring type self-locking hook, adopts precision cast steel cast to become suspension ring, Hook, hook, suspension hook lock dog blank eliminates suspension ring, Hook, hook, suspension hook lock dog blank casting internal stress suspension ring, Hook, hook, suspension hook lock dog takes out stains, feather wedge angle suspension ring are removed in grinding, Hook, hook, suspension hook lock dog boring hook on bolt overlaps external screw thread suspension ring processed, Hook, hook, suspension hook lock dog surface finish, deoil, rust cleaning, phosphatization suspension ring, Hook, hook, No. 45 round steel of the yellow electrostatic powder plastic-blasting turning on lathe of suspension hook lock dog surface connects axle, lock dog axle connects axle, turn blue and suspension ring load the hook on bolt of hook in lock dog axle surface, add spring pad, lock nut of screwing on connects axle and hook and Hook is fitted together, riveted connects axle lock dog axle and suspension hook lock dog is contained in upper end, the Hook side qualified warehouse for finished product that is packaged into of checkout facility, and suspension ring rotate freely in hook on bolt, and suspension hook lock dog is moved rear hanger body and rotated flexibly without clamping stagnation along being connected axle with Hook, Hook opens mouth mounting object, and suspension hook lock dog rebounds and blocks hook, hook seals the opening of Hook so that it is mounted object can not be deviate from.

It is a feature of the present invention that manufacture, assemble continuous-flow type operation, be suitable for producing processing in enormous quantities, guarantee both quality and quantity.
