Problems solved by technology

[0002] The glass and stone drilling machines of the prior art need to use a secondary transmission mechanism (such as a belt drive) to drive the drill bit to perform rotary drilling during use. The structure of the transmission mechanism is complex, and the maintenance workload of the subsequent secondary transmission mechanism is large. It is inconvenient. At the same time, the radial runout of the drill bit is large, the drilling accuracy is not high, and the waterproof effect of the rear end of the motor shaft that is internally conducted is not good, and water leakage is prone to occur.

Abstract

The invention discloses an integrated high-precision water passing motorized spindle structure. The integrated high-precision water passing motorized spindle structure comprises a motor shaft, motor front end bearings, a motor rotor, a motor rear end bearing, a drill bit, a rotary joint and a water passing pipe; the motor shaft sequentially penetrates through the motor front end bearings, the motor rotor and the motor rear end bearing, and the two ends of the motor shaft stretch out; the drill bit is provided with an axial through hole and connected with the front end of the motor shaft; the rotary joint is provided with an axial through hole, one end of the rotary joint is connected with the rear end of the motor shaft, and the other end of the rotary joint is rotationally connected withthe water passing pipe; and the motor shaft is internally provided with an axial through hole which communicates with the axial through holes of the water passing pipe, the rotary joint and the drillbit. The integrated high-precision water passing motorized spindle structure replaces a conventional drill bit two-stage transmission structure and is simple in structure, high in drilling precision and good in leakage-proof effect.

Description

technical field [0001] The invention relates to the technical field of glass and stone drilling machines, in particular to an integrated high-precision water-through-electric spindle structure, including a motor shaft, a motor front-end bearing, a motor rotor, a motor back-end bearing, a drill bit, a rotary joint and a water pipe. Background technique [0002] The glass and stone drilling machines of the prior art need to use a secondary transmission mechanism (such as a belt drive) to drive the drill bit to perform rotary drilling during use. The structure of the transmission mechanism is complex, and the maintenance workload of the subsequent secondary transmission mechanism is large. Inconvenient, and its drill bit radial runout is big simultaneously, and drilling precision is not high, and the motor shaft rear end waterproof effect of its internal conduction is not good, and water seepage occurs easily. Contents of the invention [0003] Aiming at the deficiencies of t...
