Description

Multi-station processing machine for water injection hole of rock drilling column tooth bit

Technical field

The invention relates to processing equipment for rock drilling cylindrical bits, and in particular to a multi-station processing machine for processing multiple water injection holes of rock drilling cylindrical bits at one time.

Background technique

The drill bit used for rock drilling is equipped with a water injection hole, and the cooling water is used to cool and discharge the drill bit to avoid damage to the drill bit due to high temperature during rock drilling, and to discharge the drilled rock fragments in a timely manner. Existing rock drilling bits use electric bench drills to process water injection holes. When the electric bench drill is working, the operator pulls the handle with his hand, and the downward pressure of the handle causes the rotating drill bit to move downward to complete the drilling. Each processing There is only one hole, but there are two water injection holes in one drill bit. Each drill bit needs to be manually clamped and fixed on the bench drill workbench for each drill bit. Therefore, the disadvantages of existing bench drills for processing water injection holes in drill bits are high labor intensity, low work efficiency, high labor wages, uneven manual pressure, large loss of drill bits, poor accuracy in processing water injection holes, and easy product scrapping.
