A wear test device for excavator bucket

Abstract

The invention discloses a wear test device of an excavator bucket, belongs to the field of mechanical manufacture, and is suitable for a wear test of the excavator bucket 5. The bucket 5 comprises a front hinge point hole and a rear hinge point hole. The wear test device of the excavator bucket comprises a test bracket 1, a driving mechanism, a material tank 2 and a material. The front hinge point hole of the bucket 5 is hinged with the test bracket 1, and the rear hinge point hole of the bucket 5 is connected with the driving mechanism. The driving mechanism drives the bucket 5 to rotate around the front hinge point hole, so as to simulate a digging process of the bucket 5. The material tank 2 is arranged below the bucket 5, and the material is placed in the material tank 2 and located in a bucket 5 rotating region, namely a digging region. The wear test device takes the friction and wear life of the bucket as a main test purpose, also gives consideration on the structure fatigue life, performs a bench test, can accurately collect bucket wear information, facilitates analysis and improvement, and besides, also greatly saves the time and cost required by whole-machine tests and customer tests.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a test device, in particular to a wear test device of an excavator bucket. Background technique [0002] Among the current construction machinery, the use of excavators has been greatly promoted and applied, and the excavation work of buckets accounts for a large part. When general customers use buckets, wear is the main failure mode. The main engine factory carries out the durability test of the whole machine and collects market feedback on various wear and tear faults, and continuously designs and improves the bucket to increase the actual service life of the bucket. [0003] However, the wear of the bucket is a long-term process. In different time periods, the wear parts and wear degrees are different. The durability of the whole machine and market feedback cannot allow designers to completely collect the above information, and thus cannot obtain reasonable ana...

[0003] However, the wear of the bucket is a long-term process. In different time periods, the wear parts and wear degrees are different. The durability of the whole machine and market feedback cannot allow designers to completely collect the above information, and thus cannot obtain reasonable analysis and improvement; and The durability of the whole machine requires specialized personnel to operate, which consumes a lot of manpower and material resources; market feedback is also obtained through service personnel, and information collection is delayed and missing, which is not conducive to the analysis and improvement of buckets
