Here the chip portion of drill bit is the equal of the installation portion for installing alloy cutting head, can be by alloy by positioning port Cutting head is stable to be connected in chip portion.
In above-mentioned planetary drilling equipment, corresponding to mode that the alloy cutting head is connected through a screw thread is fixed on At positioning port.
The mode being connected through a screw thread can enable alloy cutting head be stably connected with chip portion.
In above-mentioned planetary drilling equipment, the alloy cutting head includes cutter head and in shaft-like connecting rod, in connecting rod End is connected with cutter head, and connecting rod outer end has the breach for extending to middle part by its end together, the both sides shape of connecting rod outer end indentation, there Into flexible card, above-mentioned two card is elastically engaged at positioning port by itself.
Card itself at connecting rod outer end has certain elasticity, therefore, after the card inserted at positioning port is suitably extruded, By the elastic force of card itself with regard to that can make alloy cutting head is stable to be connected at chip portion.
Axially there is the injection channel run through in above-mentioned planetary drilling equipment, in described rotating shaft along it, it is described Rotating shaft lower end has the playpipe relative with above-mentioned drill bit.
The setting that spray sets passage can be such that blending agent enters at the hole of shaping, make hole wall smooth.
Compared with prior art, this planetary drilling equipment is due to drill bit energy rotation, while drill bit can also be relative to actively Wheel circumferentially rotates, and therefore, its borehole stability is higher, has very high practical value.
Meanwhile the planarization of processing hole wall to injection blending agent at drill bit, can be also improved in boring procedure.
