Description

Technical Field

[0001] The utility model relates to the technical field of excavator parts production equipment, in particular to a positioning mechanism for excavator parts production. Background Art

[0002] An excavator, also known as an excavating machine or backhoe, is an earth-moving machine that uses a bucket to dig up materials above or below the surface and load them onto transport vehicles or unload them into a stockpile. Excavators primarily dig soil, coal, silt, and pre-loosened soil and rock. The production and processing of an excavator requires gears, an engine, a hydraulic pump, a distribution valve, a center slewing bearing, a travel drive, a cab, control valves, a relief valve, a bucket, and a main control multi-way valve.

[0003] When installing and producing traditional buckets and tooth tips, the bucket needs to be positioned and then the tooth tips are welded to the bucket. Due to the large size of the bucket, the bucket position cannot be adjusted during welding, which makes the tooth tip welding inconvenient and affects production efficiency and yield. Therefore, it is necessary to design a positioning mechanism for the production of excavator parts. Utility Model Content

[0027] When the utility model is implemented, Figure 1 As shown. Mirror images of the support block 3 are mounted on both sides of the support block 3, with adjustable support devices 4 for assisting in supporting the bucket 1. The adjustable support devices 4 include support arms 401 hingedly connected to the side walls of the support block 3. A first rubber wheel 402 is mounted on the end of the support arm 401 away from the support block 3. A first telescopic rod 403 is hingedly connected to the base 2. The telescopic end of the first telescopic rod 403 is hingedly connected to the middle portion of the support arm 401. The telescopic end of the first telescopic rod 403 is hingedly connected to the middle portion of the support arm 401 via an axis and an axis hole. Specifically, when the first telescopic rod 403 is extended or retracted, it drives the first rubber wheel 402 on the support block 3 closer to the bucket 1, thereby supporting the bucket 1.
