Chuck is one of the key parts of coal mine tunnel drill, its performance directly affects the performance of the machine. In view of the existing problems of the hydraulic chuck, the structure of the new hydraulic chuck is designed and its working principle is briefly described. The strength of slips is analyzed by finite element method. The calculation results show that the initial design of slips meets the requirements of tunnel drilling rigs.
