Excavator bucket tooth drilling clamping device for earth-rock construction engineering machine

Abstract

The invention discloses an excavator bucket tooth drilling clamping device for an earth-rock construction engineering machine. The device comprises a shell, two springs are connected to each of two sides of the inner wall of the shell through bolts, the ends, away from the shell, of the four springs are connected with two clamping blocks through bolts, the two clamping blocks are distributed in amirror symmetry manner, the bottoms of the two clamping blocks are connected with clamping block rotating shafts through bearings, sides, away from each other, of the two clamping block rotating s hafts are welded to the bottom of the shell, a sliding block is welded to one side of the bottom of the shell, the bottom of the sliding block is in sliding connection with a sliding rail, the sides, close to each other, of the two clamping blocks are clamped with the same bucket tooth holder, and a bucket tooth tip is welded to the bottom of the bucket tooth holder. The device is good in fixing effect, the taking-out work of the bucket tooth holder is simplified, the operation step is simple, the number and density of bucket teeth can be conveniently adjusted, batched clamping of the bucket teeth can be achieved, and the drilling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering machinery, in particular to an excavating bucket tooth drilling clamping device for earthwork construction engineering machinery. Background technique [0002] At present, excavator bucket teeth are an important part of the excavator. Similar to human teeth, they are also vulnerable parts. They are combined bucket teeth composed of tooth seats and tooth tips. The bucket teeth and the excavation bucket are connected by pin shafts. The bucket teeth need to be drilled to insert the pin shafts. In the bucket tooth drilling process, a clamping device is needed to fix the bucket teeth, and then The fixed bucket teeth are drilled. The existing bucket tooth clamping device is fixed by a combination of clamps and bolts. The steps of picking and placing bucket teeth are complicated, and the clamp can only fix one bucket tooth at a time, which cannot realize the The batch drilling process o...
