Device and method for assembling chain integrally

Abstract

The invention discloses a device and method for assembling a chain integrally. The device comprises a hydraulic machine, a hydraulic machine work panel, an upper template, an upper die and a bottom board. The top face of the upper template is fixed to the bottom of a hydraulic rod of the hydraulic machine and the bottom of the upper template is fixed to the upper die. The bottom board is fixed to the upper side of the hydraulic machine work panel. A lower bolster is installed above the bottom board. A left supporting block cushion block, a right supporting block cushion block, a left supporting block and a right supporting block are arranged at the two sides of the lower bolster, wherein the left supporting block cushion block, the right supporting block cushion block, the left supporting block and the right supporting block are perpendicular to the bottom board. A core base is installed between the left supporting block cushion block and the right supporting block cushion block. Multiple locating holes are formed in the core base at intervals. Each locating hole is provided with a core base cushion block and a spring. The top end of each spring is provided with a mandrel. The method comprises the steps that firstly, localization is conducted simultaneously through the mandrels; secondly, half outer links to be assembled are arranged in located inner link sleeve holes; thirdly, hinge pins are pressed downwards; finally, the hinge pins bounce up. According to the device and method for assembling the chain integrally, operation is simple, controllability is good, and safety performance is high.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a chain forming assembly equipment and an assembly method. Background technique [0002] The chain generally consists of outer chain plates, inner chain plates, pin shafts, sleeves, rollers, locking parts and other parts; to form a complete chain, it needs to go through semi-outer link assembly, inner chain link assembly, strips, pin shafts, etc. Outcrop and riveting head, installation of locking parts and other processes; the existing half-outer link assembly and inner link assembly are all accurately positioned on the press through tooling molds, and the strip-forming process is generally done by manual work. The chain link and the small hole outer chain plate are connected together, and finally the exposed rivet head of the pin shaft and the locking piece are installed; while the hand-made strip pin and the small hole outer chain plate do not have accurate positioning equi...

[0002] The chain generally consists of outer chain plates, inner chain plates, pin shafts, sleeves, rollers, locking parts and other parts; to form a complete chain, it needs to go through semi-outer link assembly, inner chain link assembly, strips, pin shafts, etc. Outcrop and riveting head, installation of locking parts and other processes; the existing half-outer link assembly and inner link assembly are all accurately positioned on the press through tooling molds, and the strip-forming process is generally done by manual work. The chain link and the small hole outer chain plate are connected together, and finally the exposed rivet head of the pin shaft and the locking piece are installed; while the hand-made strip pin and the small hole outer chain plate do not have accurate positioning equipment, when the pin shaft enters the hole of the small hole outer chain plate, The chain plate hole is easy to produce trimming burrs, the gap between the pin shaft and the small hole outer chain plate is poor, and the pin shaft often has rough phenomenon, resulting in very hot wear, the service life of the chain will be reduced, and the labor intensity of the workers is high.
