[CN 201910693046.9] A Hydraulic-Mechanical Integrated Drilling and Cutting Radial Grooving Device


[CN 201910693046.9] Title of a hydraulic-mechanical combined drilling and cutting integrated radial grooving device: Application number of a hydraulic-mechanical combined drilling and cutting integrated radial grooving device: CN 201910693046.9 Applicant: China University of Mining and Technology Application Date: 2019-7-30 Patent Type: Invention Application The present invention discloses a hydraulic-mechanical combined drilling and cutting integrated radial grooving device, including a housing body; The main drive shaft and the secondary drive shaft are arranged inside the housing body; the common boring bit is connected with the housing body through a connector; the hollow part of the common boring bit forms a high-pressure water outlet; the connector is an axial hollow structure, the hollow part forms a main shaft travel channel, and the connector is connected with the main drive shaft through the main shaft travel channel; the front end of the main drive shaft is arranged with a primary spring; the front end of the secondary drive shaft is arranged with a secondary spring; an oblique cutter groove is provided on both sides of one end of the main transmission shaft close to the secondary transmission shaft; the grooving blade is arranged in the oblique cutter groove through a fixed pin. The use of hydraulic way to achieve the groove cutting blade extension and recovery. Compared with the prior art, the efficiency and stability of the groove cutting are improved, and the time and labor cost of the groove cutting process are reduced.
