Description

A Drilling Fixture for Shafts Convenient for Disassembly and Replacement

technical field

The utility model belongs to the technical field of a shaft drilling jig that is easy to disassemble and replace, in particular to a shaft drilling jig that is easy to disassemble and replace.

Background technique

Track rollers and guide wheels are an integral part of crawler-type traveling mechanisms such as bulldozers and excavators. They either bear the weight of the fuselage, or guide the chain crawler to run, so they play a vital role in the normal operation of the crawler walking mechanism. Because the crawler-type walking mechanism is widely used in construction machinery, it is mostly used in harsh environments such as ore mining and construction excavation. In order to ensure the service life of the rollers and guide wheels, their processing has strict and systematic requirements.

In the current operation of the shaft drilling jig, the fixed clamp block cannot be replaced separately. In the later use process, the fixed clamp block cannot be repaired separately after it is damaged. This will cause inconvenience in future use and is also a waste. Therefore, there is a need for a shaft drilling jig that is easy to disassemble and replace, so as to solve the deficiencies in the prior art.
