Connecting pin assembly and wear system for connecting wear parts to implements

Abstract

The invention relates to the technical field of connecting pins, and discloses a connecting pin assembly and a wearing system for connecting wearing parts to a machine tool. The connecting pin assembly includes: a connecting pin and a pin sleeve, and the pin sleeve is set on the connecting pin; One end of one end has a first end surface, and the side of the connecting pin close to the first end surface is provided with a second end surface; wherein, one of the first end surface and the second end surface is provided with a plurality of installation grooves, and the other of the two is provided with a plurality of installation grooves. One has a plurality of card slots; the installation slots and the card slots are four, eight or twelve, and are evenly distributed on the first end surface or the second end surface; a plurality of elastic fasteners, elastic fasteners It is arranged in the installation groove; the connecting pin can rotate relative to the pin sleeve, so that the elastic engaging part snaps into or disengages from the slot. The advantages of the present invention are that the connecting pin assembly is easy to process, is not susceptible to failure due to the influence of mud, sand and water, and has high structural strength.

Description

technical field [0001] The invention relates to the technical field of connecting pins, in particular to a connecting pin assembly and a wearing system for connecting wearing parts to implements. Background technique [0002] Excavation machines move soil, rocks, sundries or other materials by digging, splitting or otherwise. Such machines are usually equipped with buckets, and the teeth on the buckets, such wearing parts, are worn out during repeated operations. It is easy to be worn, so after such wearing parts are worn to a certain extent, they need to be replaced in time. [0003] Existing wear parts of this type are fixed to the machine tool by welding, but it is inconvenient to replace after wear; there are also wear parts that are fixed to the machine tool by hammering, usually the hammering is not in place, And at the scene of machine tool operation, usually there is no hammering tool, it is inconvenient to install. Therefore, as disclosed in the patent "CN10636826...

Problems solved by technology

In this scheme, the outer cylindrical surface of the center pin is provided with a plurality of braking grooves along its axial direction, which are used to cooperate with the elastic braking parts. During the long-term operation of the machine tool, muddy water, Sand and soil will fill the brake groove, resulting in the failure of the brake structure, and it is easy to get stuck. The processing of the brake groove is inconvenient, and because the center pin is a directly stressed part, the brake groove setting weakens the strength of the center pin
